Exercise ameliorates muscular excessive mitochondrial fission, insulin resistance and inflammation in diabetic rats via irisin/AMPK activation

This study aimed to investigate the effects of exercise on excessive mitochondrial fission, insulin resistance, and inflammation in the muscles of diabetic rats. The role of the irisin/AMPK pathway in regulating exercise effects was also determined. Thirty-two 8-week-old male Wistar rats were randomly divided into four groups (n = 8 per group): one control group (Con) and three experimental groups. Type 2 diabetes mellitus (T2DM) was induced in the experimental groups via a high-fat diet followed by a single intraperitoneal injection of streptozotocin (STZ) at a dosage of 30 mg/kg body weight. After T2DM induction, groups were assigned as sedentary (DM), subjected to 8 weeks of treadmill exercise training (Ex), or exercise training combined with 8-week cycloRGDyk treatment (ExRg). Upon completion of the last training session, all rats were euthanized and samples of fasting blood and soleus muscle were collected for analysis using ELISA, immunofluorescence, RT-qPCR, and Western blotting. Statistical differences between groups were analyzed using one-way ANOVA, and differences between two groups were assessed using t-tests. Our findings demonstrate that exercise training markedly ameliorated hyperglycaemia, hyperlipidaemia, and insulin resistance in diabetic rats (p < 0.05). It also mitigated the disarranged morphology and inflammation of skeletal muscle associated with T2DM (p < 0.05). Crucially, exercise training suppressed muscular excessive mitochondrial fission in the soleus muscle of diabetic rats (p < 0.05), and enhanced irisin and p-AMPK levels significantly (p < 0.05). However, exercise-induced irisin and p-AMPK expression were inhibited by cycloRGDyk treatment (p < 0.05). Furthermore, the administration of CycloRGDyk blocked the effects of exercise training in reducing excessive mitochondrial fission and inflammation in the soleus muscle of diabetic rats, as well as the positive effects of exercise training on improving hyperlipidemia and insulin sensitivity in diabetic rats (p < 0.05). These results indicate that regular exercise training effectively ameliorates insulin resistance and glucolipid metabolic dysfunction, and reduces inflammation in skeletal muscle. These benefits are partially mediated by reductions in mitochondrial fission through the irisin/AMPK signalling pathway.

Is the cardioprotective effect of pre-infarction angina blunted by age?

Abstract Funding Acknowledgements None. Background Pre-infarct angina (PIA) has been demonstrated to reduce infarct size and improve prognosis in ST-elevation myocardial infarction (STEMI). However, the effects of ischemic preconditioning with aging are still controversial. Purpose We aimed at comparing the effect of pre-infarction angina (PIA) on infarct size between two age groups. Methods We retrospectively studied consecutive STEMI patients treated by primary percutaneous coronary intervention (PCI) from January 2008 to December 2017. PIA was diagnosed if a patient had arm, jaw, or chest pain in the preceding eight days. Peak creatine kinase (CK) concentration was used as a surrogate of infarct size. Patients were divided into two groups, based on the median age: ≤62 years and &amp;gt;62 years. Multiple linear regression was used to identify independent predictors for infarct size that included total ischemic time and classic cardiovascular risk factors (hypertension, diabetes, dyslipidaemia, and smoking). Interaction between age and PIA was evaluated by 2-way factorial ANOVA. Results From the 1131 patients included in the study, 590 (52,2%) had ≤62 years and 541 (47,8%) had &amp;gt;62 years. Older patients were more often women (17.2% vs 8.6%, p&amp;lt;0.001) and had longer total ischemic time [4.6(3.0-9.0) vs 3.5(2.3-6.0) hours, p&amp;lt;0.001]. They also had higher prevalence of hypertension (32.8% vs 22.8%, p&amp;lt;0.001), diabetes (30.7% vs 18.7%, p&amp;lt;0.001) and were less likely to be smokers (26.9% vs 71.4%, p&amp;lt;0.001). The prevalence of PIA was similar across age groups (≤62Y 31.2% vs &amp;gt;62Y 32.0%, p=0.668). In older patients, PIA was associated with smaller infarct size [1.29(0.72-2.33) vs. 1.76(0.97-2.91) U/Lx103, p&amp;lt;0.001]. This difference was not observed for younger patients [1.72(0.95-3.40) vs. 1.81(0.94-3.37) U/Lx103, p=0.392]. There was no significant interaction between the existence of PIA and age on peak CK (p=0.280 for interaction) (Figure 1). In multivariate analysis, overall, PIA was associated with reduced peak CK (β=-0,320, p=0.011). On subgroup group analysis, PIA was a predictor of infarct size only in the older patients (β=-0,459, p=0.005), but not in the younger group (β=-0,182, p=0.394). Conclusion Older patients with PIA had significantly lower infarct size compared to patients in the same age group without PIA. After adjustment for risk factors and total ischemic time, PIA was a predictor of lower infarct size only for the older patients. These results suggest that the effect of pre-ischemic conditioning is not blunted by age, indicating that older patients should not be excluded from clinical trials investigation of cardioprotective strategies in STEMI patients.

Taste alteration and its relationship with nutritional status among cancer patients receiving chemotherapy, cross-sectional study

The aim of this study is to determine the prevalence of taste alterations (TAs) during chemotherapy and their association with nutritional status and malnutrition. In addition to the associated factors with TA, including sociodemographic health-related factors and clinical status, and to investigate coping strategies to manage TA. A multicenter cross-sectional design study was conducted on 120 cancer patients aged at least 18 who had been undergoing at least one round of chemotherapy. TAs were evaluated using the chemotherapy-induced taste alteration scale (CiTAS), the malnutrition universal screening tool (MUST) was used for nutritional screening, the antineoplastic side effects scale (ASES) was used for subjective assessment of chemotherapy side effects, and the Charlson comorbidity index (CCI) was used for comorbidity assessment. SPSS21 software was used to analyze the data, and the independent T-test and one-way ANOVA test were used to determine the association between TAs and a variety of related variables. The prevalence of TAs was 98.3%. Among participants, 48.3% were at low risk of malnutrition, 20% at medium risk, and 31.7% at high risk. Malnutrition risk was associated with taste disorders (p&lt;0.05). Patients’ age, gender, educational level, and physical status were associated with TAs (p&lt;0.05). Type of cancer, chemotherapy regimen, and number of chemotherapy cycles were also associated with TAs (p&lt;0.05). A variety of antineoplastic side effects were associated with TAs (p&lt;0.05), including nausea, vomiting, dry mouth, sore mouth and throat, excessive thirst, swallowing difficulty, appetite changes, weight loss, dizziness, lack of energy, disturbed sleep, anxiety, and difficulty concentrating. TAs were associated with an increased number of comorbidities, and individuals with diabetes, pulmonary diseases, and hypertension were associated with TAs (P&lt;0.05). Patients in this study rarely practice self-management strategies to cope with TAs. A high prevalence (98.3%) of TAs in cancer patients receiving chemotherapy was found, and it was linked to a variety of negative outcomes. Chemotherapy-induced TAs are an underestimated side effect that requires more attention from patients and health care providers.

The effect of intraoperative low-dose ketamine versus dexmedetomidine infusion on postoperative bowel recovery in patients undergoing gastrointestinal malignancy surgeries: Placebo-controlled, randomized trial

Abstract Background and Aims: No studies have compared the effects of ketamine and dexmedetomidine on bowel recovery. We evaluated the effects of intraoperative low-dose ketamine or dexmedetomidine infusion on postoperative bowel recovery in patients undergoing gastrointestinal (GI) malignancy surgeries. Material and Methods: This placebo-controlled, randomized study was carried out in 84 American Society of Anesthesiologists II patients, aged 18–70 years, of either gender, undergoing elective open GI malignancy surgeries. Patients received intraoperative infusion of ketamine @ 0.1 mg kg-1 h-1 (KET), dexmedetomidine @ 0.25 μg kg-1 h-1 (DEX), or normal saline (placebo). Primary outcome was the time to first flatus and/or stool. Secondary outcomes included time to extubation, total analgesic requirement, postoperative pain scores, time to feeds, duration of intensive care unit (ICU) and hospital stay, and the incidence of adverse events. Continuous data were analyzed by the one-way analysis of variance (ANOVA) or the Kruskal–Wallis test. Categorical data were analyzed by the Chi-square test or the Fisher’s exact test. Results: Median time to passage of flatus and/or stool was 3 [interquartile range (IQR) 2–3] days in the KET group, 2 [IQR 2–3] days in the DEX group, and 2 [IQR 2–3] days in the placebo group (P = 0.53 for placebo vs. KET, 0.81 for placebo vs. DEX, and 0.99 for KET vs. DEX). Pain scores and analgesic consumption were significantly less in the intervention groups versus placebo (P &lt; 0.001). No difference was seen in other secondary outcomes. Conclusion: Low-dose ketamine or dexmedetomidine did not result in early bowel recovery despite lower pain scores and opioid consumption in patients undergoing open GI malignancy surgeries. Key Message: What is known: Ketamine and dexmedetomidine may promote bowel recovery by improving analgesia and decreasing opioid usage.Main findings: This randomized controlled trial found no evidence of earlier bowel recovery with ketamine or dexmedetomidine versus placebo despite lower pain scores and analgesic consumption in the ketamine and dexmedetomidine groups.

The Effect of Brain Anodal and Cathodal Transcranial Direct Current Stimulation on Psychological Refractory Period at Different Stimulus-Onset Asynchrony in Non-Fatigue and Mental Fatigue Conditions

The psychological refractory period (PRP) effect occurs when two stimuli that require separate responses are presented sequentially, particularly with a short and variable time interval between them. Fatigue is a suboptimal psycho-physiological state that leads to changes in strategies. In recent years, numerous studies have investigated the effects of transcranial direct current stimulation (tDCS) on motor control. The present study aimed to investigate the effects of two tDCS methods, anodal and cathodal, on PRP in ten different conditions of stimulus-onset asynchronies (SOAs) under non-fatigue and mental fatigue conditions. The participants involved 39 male university students aged 19 to 25 years. In the pre-test, they were assessed using the PRP measurement tool under both non-fatigue and mental fatigue conditions. The mental fatigue was induced by a 30-min Stroop task. The test consisted of two stimuli with different SOAs (50, 75, 100, 150, 300, 400, 600, 900, 1200, and 1500 ms). The first was a visual stimulus with three choices (letters A, B, and C). After a random SOA, the second stimulus, a visual stimulus with three choices (colors red, yellow, and blue), was presented. Subsequently, participants were randomly assigned to the anodal, cathodal, and sham stimulation groups and underwent four consecutive sessions of tDCS stimulation. In the anodal and cathodal stimulation groups, 20 min of tDCS stimulation were applied to the PLPFC area in each session, while in the sham group, the stimulation was artificially applied. All participants were assessed using the same measurement tools as in the pre-test phase, in a post-test phase one day after the last stimulation session, and in a follow-up phase four days after that. Inferential statistics include mixed ANOVA, one-way ANOVA, independent, and dependent t-tests. The findings indicated that the response time to the second stimulus was longer at lower SOAs. However, there was no significant difference between the groups in this regard. Additionally, there was no significant difference in response time to the second stimulus between the fatigue and non-fatigue conditions, or between the groups. Therefore, tDCS had no significant effect. There was a significant difference between mental fatigue and non-fatigue conditions in the psychological refractory period. Moreover, at lower SOAs, the PRP was longer than at higher SOAs. In conditions of fatigue, the active stimulation groups (anodal and cathodal) performed better than the sham stimulation group at higher SOAs. Considering the difference in response to both stimuli at different SOAs, some central aspects of the response can be simultaneously parallel. Fatigue also affects parallel processing. This study supports the response integration phenomenon in PRP, which predicts that there will be an increase in response time to the first stimulus as the interval between the presentation of the two stimuli increases. This finding contradicts the bottleneck model. In this study, the effectiveness of cathodal and anodal tDCS on response time to the second stimulus and PRP was found to be very small.

Evaluating the Effectiveness of Phellodendron Amurense Ruprecht Extract as a Natural Anti-Caries Material

Background: This study aimed to investigate the antibacterial and cytotoxic potential of Phellodendron amurense Ruprecht (PAR) extract against Streptococcus mutans (S. mutans) and explore the possibility of using PAR extract as an anticariogenic agent. Methods: Mixed extracts were prepared at 0, 1.25, 2.5, and 5 mg/mL concentrations, and an S. mutans-containing solution of 100 μL was inoculated into the medium. The survival rate of human keratinocyte (HaCaT) cells was assessed to confirm stability. One-way ANOVA was performed to evaluate the antibacterial activity against S. mutans and the proliferation of HaCaT cells. Results: Higher concentrations of the PAR extract showed more growth inhibition of S. mutans over time, with the complete inactivation of S. mutans at 5 mg/mL. HaCaT cell density was reduced at a PAR extract concentration of 1.25 mg/mL, but IC50 was not observed, confirming that the concentration used did not affect the cytotoxicity and proliferation. Conclusions: Results showed that the PAR extract was excellent as a natural substance with anticariogenic effects that inhibited the growth of S. mutans and did not affect the cell viability, thus indicating the potential for clinical application.

Association between NDUFS1 from urinary extracellular vesicles and decreased differential renal function in children with ureteropelvic junction obstruction

BackgroundUreteropelvic junction obstruction (UPJO) is the most common cause of pediatric congenital hydronephrosis, and continuous kidney function monitoring plays a role in guiding the treatment of UPJO. In this study, we aimed to explore the differentially expressed proteins (DEPs) in the urinary extracellular vesicles(uEVs) of children with UPJO and determine potential biomarkers of uEVs proteins that reflect kidney function changes.MethodsPreoperative urine samples from 6 unilateral UPJO patients were collected and divided into two groups: differential renal function (DRF) ≥ 40% and DRF < 40%.We subsequently used data-independent acquisition (DIA) to identify and quantify uEVs proteins in urine, screened for DEPs between the two groups, and analyzed biofunctional enrichment information. The proteomic data were evaluated by Western blotting and enzyme-linked immunosorbent assay (ELISA) in a new UPJO testing cohort.ResultsAfter one-way ANOVA, a P adj value < 0.05 (P-value corrected by Benjamin–Hochberg) was taken, and the absolute value of the difference multiple was more than 1.5 as the screening basis for obtaining 334 DEPs. After analyzing the enrichment of the DEPs according to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment combined with the protein–protein interaction (PPI) network results, we selected nicotinamide adenine dinucleotide-ubiquinone oxidoreductase core subunit S1 (NDUFS1) for further detection. The expression of NDUFS1 in uEVs was significantly lower in patients with DRF < 40% (1.182 ± 0.437 vs. 1.818 ± 0.489, P < 0.05), and the expression level of NDUFS1 was correlated with the DRF in the affected kidney (r = 0.78, P < 0.05). However, the NDUFS1 concentration in intravesical urine was not necessarily related to the change in DRF (r = 0.28, P = 0.24).ConclusionsReduced expression of NDUFS1 in uEVs might indicate the decline of DRF in children with UPJO.

The Effect of Technological Pedagogical Content Knowledge (TPACK) on Rural Area Students’ English Writing

This research was conducted to examine the impact of the Technological Pedagogical Content Knowledge (TPACK) and Direct Learning (DL) model on the learning outcomes of students in rural areas concerning English descriptive text composition. The models introduced a meaningful learning experience within conventional classroom settings, enabling students to connect prior knowledge with new information in creating innovative ideas. TPACK model played an essential role in the educational system, facilitating teachers in integrating technological, pedagogical, and content knowledge throughout the instructional process. Therefore, students became more engaged, active, and enthusiastic participants in their learning. An authentic experimental and control group design was carried out in two parallel classes at a senior high school. Meanwhile, ANOVA Factorial (2-way ANOVA) was used to analyze the data. The results showed that the learning outcomes of TPACK were significantly different from those of the DL group. Therefore, TPACK substantially affected the learning outcomes of students in writing English descriptive text. This research reported the valuable contribution of the model in equipping future teachers with the knowledge necessary to integrate content, learning theories, teaching models, methods, and technology into their instructional practices.

Assessing Saudi EFL Learners’ Use and Understanding of English Idioms: Perceptions, Problems, and Patterns of Learning

This study aims to investigate Saudi EFL learners’ perceptions of English idioms, their problems, and the patterns of their learning and understanding of English idioms. 458 students (around 10%) were selected through a random sampling method from the undergraduate learners in different levels of programs at the College of Business Administration and the College of Science &amp; Humanities, Prince Sattam bin Abdulaziz University, Al-Kharj, KSA. As the study looked at how certain independent variables (gender, level/year of study, and parents’ profession) shaped dependent variables (perceptions/attitudes), a questionnaire was self-developed which includes modified items from existing research. A quantitative approach (descriptive statistics) was used to analyze the data. The findings revealed that Saudi EFL learners’ perceptions were very positive about English idioms and their impact on enhancing their English proficiency. It was found that lack of background information, unfamiliarity, variation in literal interpretation, lack of Arabic parallels, and insufficient EFL classroom training made learning English idioms challenging for respondents. It was also revealed that Saudi EFL learners acquired and comprehended English idioms via using them in sentences, consulting a dictionary, guessing from contexts, group discussions, and breaking them down into their constituent parts. One-way ANOVA analysis found no statistically significant difference among the respondents based on their demographic differences. The study holds implications for both teachers and students as it will help them teach and learn English idioms effectively. The most common method is translating English idioms into their language.

AN ASSOCIATION OF METABOLIC SYNDROME WITH NONALCOHOLIC FATTY LIVER DISEASE

Objectives: Nonalcoholic fatty liver disease is strongly linked with hepatic fatty infiltration and visceral adiposity, therefore, being a cause and a result of metabolic syndrome. The objective of the study is to find an association of metabolic syndrome (MetS) with nonalcoholic fatty liver disease (NAFLD). Methods: A total of 342 subjects from which 86 NAFLD 86 control were suitably selected for study duration of 1 year. Diagnosis of nonalcoholic fatty liver disease was done by liver imaging and based on liver enzymes. MetS assessment was done by the national cholesterol education program adult treatment panel III (NCEP ATP III) criteria. Estimation of all biochemical and hematological parameters and liver enzymes was done following standard guidelines. Mean comparison of quantitative data in different groups was analyzed with one-way analysis of variance. Results: There were significant high levels of body mass index, waist circumference, and lipid profiles in NAFLD patients in comparison to control population (p&lt;0.001). According to the NCEP ATP III criteria, 59.3% of NAFLD were present with MetS where risk estimate was significant (odds ratio=2.15). Conclusion: This study suggests that there is an increased in all the components of MetS and gross changes in biochemical markers in cases of NAFLD. Therefore, whenever MetS factors are met in the clinical checkups, patients must be diagnosed for NAFLD by imaging (fatty liver).

Quality of life and its related-influencing factors in patients with cervical cancer based on the scale QLICP-CE(V2.0)

BackgroundQuality of life research can guide clinical workers to adopt more targeted treatment and intervention measures, so as to achieve the purpose of improving patients’ quality of life. The objective of this study was to evaluate health-related quality of life in Chinese patients with cervical cancer and to explore its influencing factors.MethodsA total of 186 patients with cervical cancer were investigated by using the QLICP-CE (V2.0) scale (Quality of Life Instruments for Cancer Patients-Cervical Cancer) developed by our group in China. The data were analyzed by t-test, one-way ANOVA, univariate analysis, and multivariate linear regression.ResultsThe total score of quality of life scale for cervical cancer patients was (62.58 ± 12.69), Univariate analysis of objective clinical indexes showed that creatinine concentration was a negative influence factor in the psychological domain, potassium ion concentration was a negative influence factor in the common symptoms and side effect domain, erythrocyte content was a positive influence factor physical domain and common general domain. Multiple linear regression results suggested that clinical staging was the influencing factor of common symptom and side effect domain, common general module and total score of scale. Marital status has different degrees of influence on the psychological, social, and common general domains. The level of education also influenced scores in the social domain.ConclusionThe total score of quality of life in patients with cervical cancer who received active treatment was acceptable. Marital status, clinical staging, and educational level are the factors that affect the quality of life of patients with cervical cancer. At the same time, potassium ion concentration, red blood cell count and creatinine concentration also have important effects on quality of life in patients with cervical cancer. Therefore, it is very important to give personalized treatment and nursing to patients based on various factors.

Impact of rainfall on the water quality of a tropical river: based on the Nilwala River in the southern province of Sri Lanka between March and October 2019

ABSTRACT The study addresses the pressing need for an effective monitoring system to assess aquatic water quality, given the exacerbating impact of climate change on surface water bodies. Focusing on the Nilwala River, the research pursues three main objectives: comparative analysis of the Weighted Arithmetic Water Quality Index (WAWQI) values across different river locations, exploration of correlations between monthly rainfall and various physicochemical parameters at distinct sampling sites, and examination of notable disparities in the WAWQI between dry and wet months. Data collected from eight river locations from March to October 2019 revealed significant temporal variations in pH, temperature, chemical oxygen demand (COD), electrical conductivity (EC), alkalinity, chloride (Cl−), and nitrate (NO3-) content. The WAWQI increased across all sites during the drought, with only Site 4 (Wellathota) deemed suitable for drinking. Statistical analyses using an one-way ANOVA and multiple linear regressions unveiled significant relationships between rainfall and pH, biological oxygen demand (BOD), EC, and total alkalinity. The total alkalinity is the most affected parameter by the rainfall. Rainfall positively predicted BOD, COD, and NO3- concentration while negatively predicting other parameters.

Relationship between paraspinal muscle properties and bone mineral density based on QCT in patients with lumbar disc herniation

ObjectiveIncreasing research suggests that paraspinal muscle fat infiltration may be a potential biological marker for the assessment of osteoporosis. Our aim was to investigate the relationship between lumbar paraspinal muscle properties on MRI and volumetric bone mineral density (vBMD) based on QCT in patients with lumbar disc herniation (LDH).MethodsA total of 383 patients (aged 24–76 years, 193 females) with clinically and radiologically diagnosed LDH were enrolled in this retrospective study. The muscle cross-sectional area (CSA) and the proton density fat fraction (PDFF) were measured for the multifidus (MF), erector spinae (ES) and psoas major (PS) at the central level of L3/4, L4/5 and L5/S1 on lumbar MRI. QCT was used to measure the vBMD of two vertebral bodies at L1 and L2 levels. Patients were divided into three groups based on their vBMD values: normal bone density group (> 120 mg/cm3), osteopenia group (80 to 120 mg/cm3) and osteoporosis group (< 80 mg/cm3). The differences in paraspinal muscle properties among three vBMD groups were tested by one-way ANOVA with post hoc analysis. The relationships between paraspinal muscle properties and vBMD were analyzed using Pearson correlation coefficients. Furthermore, the association between vBMD and paraspinal muscle properties was further evaluated using multiple linear regression analysis, with age and sex also included as predictors.ResultsAmong the 383 LDH patients, 191 had normal bone density, 129 had osteopenia and 63 had osteoporosis. In LDH patients, compared to normal and osteopenia group, paraspinal muscle PDFF was significantly greater in osteoporosis group, while paraspinal muscle CSA was lower (p < 0.001). After adjusting for age and sex, it was found that MF PDFF and PS CSA were found to be independent factors influencing vBMD (p < 0.05).ConclusionIn patients with LDH, paraspinal muscle properties measured by IDEAL-IQ sequence and lumbar MR scan were found to be related to vBMD. There was a correlation between the degree of paraspinal muscle PDFF and decreasing vBMD, as well as a decrease paraspinal muscle CSA with decreasing vBMD. These findings suggest that clinical management should consider offering tailored treatment options for patients with LDH based on these associations.

Frequency of Erectile Dysfunction in Patients with Type 2 Diabetes Mellitus Presenting with Peripheral Neuropathy at a Tertiary Care Hospital

Background: Erectile dysfunction (ED) is notably prevalent among patients with type 2 diabetes mellitus (T2DM), especially those suffering from peripheral neuropathy. The condition significantly impacts the quality of life and is often exacerbated by diabetes-related complications. Objective: This study aims to ascertain the frequency and severity of ED among patients with T2DM and peripheral neuropathy, and to examine the association between ED and variables such as age, duration of diabetes, and glycemic control. Methods: A prospective cohort study was conducted at the Baqai Institute of Diabetology and Endocrinology, Karachi, from July 2021 to September 2022. We included 115 male patients aged 35-65 years with T2DM and diagnosed peripheral neuropathy. ED was assessed using the Urdu version of the International Index of Erectile Function-5 (IIEF-5) questionnaire. Demographic details, medical history, and laboratory results were collected and analyzed using SPSS version 25. Statistical tests included chi-squared and one-way ANOVA, with a significance level set at p&lt;0.05. Results: The mean age of the participants was 50.97 ± 7.21 years, and the average duration of diabetes was 9.37 ± 6.56 years. The mean IIEF-5 score was 14.33 ± 6.0, indicating moderate ED. Severe ED was observed in 20% of the participants, moderate ED in 19.1%, and mild to moderate ED in 28.7%. The study found a significant association between the duration of diabetes and ED severity (p &lt; 0.001), while age and HbA1c levels did not show a significant correlation with ED status. Conclusion: ED is highly prevalent and severe among patients with T2DM and peripheral neuropathy, with disease duration being a significant predictor of ED severity. These findings underscore the need for early screening and targeted interventions in this population.

Increased Gene Expression of LITAF, TNF-α and BCL6 in Endometrial Tissues of Women with Endometriosis: A Case-Control Study.

Endometriosis, as a common inflammatory chronic disease is characterized by endometrial tissue growth outside the uterine cavity. It was reported that lipopolysaccharides (LPS) activate a transcription factor called LPSinduced tumor necrosis factor-alpha (LITAF) in macrophages, which induced transcription of cytokine genes such as tumor necrosis factor alpha (TNF-α). B-cell lymphoma 6 protein (BCL6) is a transcription factor which expression was increased in endometrial tissues of infertile women with endometriosis. In addition, it was shown that mRNA and protein of LITAF and BCL6 were inversely related in mature B lymphocytes and B-Cell lymphomas. Accordingly, we investigated gene expression of LITAF, BCL6 and ,TNF-α in eutopic and ectopic endometrial tissues of women with endometriosis compared to the controls. In this case-control study, 10 women with endometriosis (endometriosis group) and 10 women without endometriosis (control group) enrolled after diagnostic laparoscopy. Real-time polymerase chain reaction (PCR) technique was used to quantitatively analyze gene expression. One-Way ANOVA was used for data analysis. This study showed that LITAF gene expression was significantly higher in ectopic endometrial tissues compared to the control samples. Expression level of BCL6 gene was significantly increased in the ectopic tissues of women with endometriosis compared to the control and eutopic samples. Although TNF-ɑ gene expression was increased in the ectopic lesions compared to the eutopic and control endometrial samples, these differences were not significant. The results suggested that over-expression of these inflammatory genes in ectopic endometrial lesions can be considered as a molecular scenario in pathophysiology of endometriosis by induction of inflammatory cascades and cellular proliferation.

Optimization of Hypericum Perforatum Microencapsulation Process by Spray Drying Method

Hypericum perforatum (HP) contains valuable and beneficial bioactive compounds that have been used to treat or prevent several illnesses. Encapsulation technology offers protection of the active compounds and facilitates to expose of the biologically active compounds in a controlled mechanism. Microcapsulation of the hydroalcoholic gum arabic and maltodextrin have hot been used as wall materials in the encapsulation of HP extract. Therefore, the optimum microencapsulation parameters of Hypericum perforatum (HP) hydroalcoholic extract were determined using response surface methodology (RSM) for the evaluation of HP extract. Three levels of three independent variables were screened using the one-way ANOVA. Five responses were monitored, including total phenolic content (TPC), 2,2-Diphenyl-1-picrylhydrazyl (DPPH), carr index (CI), hausner ratio (HR), and solubility. Optimum drying conditions for Hypericum perforatum microcapsules (HPMs) were determined: 180 °C for inlet air temperature, 1.04/1 for ratio of maltodextrin to gum arabic (w/w), and 1.98/1 for coating to core material ratio (w/w). TPC, antioxidant activity, CI, HR, and solubility values were specified as 316.531 (mg/g GAE), 81.912%, 6.074, 1.066, and 35.017%, respectively, under the optimized conditions. The major compounds of Hypericum perforatum (hypericin and pseudohypericin) extract were determined as 4.19 μg/g microcapsule and 15.09 μg/g microcapsule, respectively. Scanning electron microscope (SEM) analysis revealed that the mean particle diameter of the HPMs was 20.36 µm. Based on these results, microencapsulation of HPMs by spray drying is a viable technique which protects the bioactive compounds of HP leaves, facilitating its application in the pharmaceutical, cosmetic, and food industries.Graphical

Antenatal creatine supplementation reduces persistent fetal lung inflammation and oxidative stress in an ovine model of chorioamnionitis.

Background Chorioamnionitis is a common antecedent of preterm birth and induces inflammation and oxidative stress in the fetal lungs. Reducing inflammation and oxidative stress in the fetal lungs may improve respiratory outcomes in preterm infants. Creatine is an organic acid with known anti-inflammatory and antioxidant properties. Objective To evaluate the efficacy of direct fetal creatine supplementation to reduce inflammation and oxidative stress in fetal lungs arising from an in utero pro-inflammatory stimulus. Methods Fetal lambs (n=51) were instrumented at 90 days gestation to receive a continuous infusion of creatine monohydrate (6 mgkg-1h-1) or saline for 17 days. Maternal chorioamnionitis was induced with intra-amniotic lipopolysaccharide (LPS; 1 mg, O55:H6) or saline seven days before delivery at 110 days gestation. Tissue creatine content was assessed with capillary electrophoresis, and inflammatory markers were analyzed with Luminex Magpix and immunohistochemistry. Oxidative stress was measured as the level of protein thiol oxidation. The effects of LPS and creatine were analyzed using a 2-way ANOVA. Results Fetal creatine supplementation increased lung creatine content by 149% (PCr<0.0001) and had no adverse effects on lung morphology. LPS-exposed groups showed increased levels of interleukin-8 in the bronchoalveolar lavage (PLPS<0.0001) and increased levels of CD45+ leukocytes (PLPS<0.0001) and MPO+ (PLPS<0.0001) cells in the lung parenchyma. Creatine supplementation significantly reduced the levels of CD45+ (PCr=0.045) and MPO+ cells (PCr=0.012) in the lungs and reduced thiol oxidation in plasma (PCr<0.01) and lung tissue (PCr=0.02). Conclusion Fetal creatine supplementation reduced markers of inflammation and oxidative stress in the fetal lungs arising from chorioamnionitis.

An improved diagnostic method for taurodontism and a comparative study on its effectiveness evaluation.

The two commonly used diagnostic methods for taurodontism are susceptible to aging changes, mastication wear and other factors. Therefore, this study proposed an improved diagnostic method for taurodontism, and compared it with the previous two methods as a supplement for taurodontism diagnosis. The included patients were aged 10-89 years and admitted to the Department of Stomatology of Hebei Eye Hospital from June 1, 2022 to May 31, 2023. Eighty cone-beam computed tomography images were divided equally into 4 groups: 10-29, 30-49, 50-69, and 70-89 years old. The right mandibular first molars were selected as measurement objects. Firstly, |BD| and taurodontism index (TI)-related parameters were measured using Shifman and Chanannel's method and crown-body(CB) and root (R) lengths was measured by Seow and Lai's method. The improved method used the length from the cementoenamel junction(CEJ) to the root bifurcation point(body, B)and the root length(root, R)as the measurement objects. Finally, TI, CB/R ratios, and B/R ratios were calculated according to the formulas given below. One-way ANOVA analysis was mainly used to compare the differences in the values, indices and ratios of taurodontism among different age groups (p<0.05). With the increase of age, |BD| and TI values decreased significantly (p<0.01). The CB/R ratios of 70-89 years group were significantly lower than those of the other three groups (p<0.01). Ratios derived from the improved method were significantly lower in the 70-89 years than in 10-29 years group (p<0.05). The |BD| and TI parameters proposed by Shifman and channel are significantly influenced by age. The measurements of Seow and Lai (CB/R ratios) were less affected by age compared with those of the former. The improved method(B/R ratios) was least affected by age, which would reduce error and bias in the measurement of taurodontism and obtain more objective results in older patients.

Fracture load of chairside CAD-CAM veneers fabricated with pre-and fully crystalized lithium disilicate ceramics.

To evaluate the fracture load of chairside computer-aided design and computer-aided manufacturing (CAD-CAM) veneers fabricated with two conventional pre-crystallized and two fully crystallized lithium disilicate ceramic materials. Seventy-five chairside CAD-CAM veneers (15 specimens/group) for maxillary right central incisors were fabricated with different lithium disilicate brands: (1) IPS e.max CAD; (2) Amber Mill; (3) Cerec Tessera; (4) n!ce Straumann; and (5) GC Initial LiSi Block. Restorations were cemented with resin luting cement (Variolink Esthetic, Ivoclar) to 3D-printed resin dies. Bonded restorations received 5000 thermal cycles and then were loaded until fracture. Statistical analysis included One-Way ANOVA. Conventional pre-crystallized e.max CAD displayed the highest fracture load value (640 N), followed by fully-crystallized n!ce Straumann (547 N), pre-crystallized Cerec Tessera (503 N), pre-crystallized Amber Mill (476 N), respectively; fully-crystallized GC Initial LiSi Block (431 N) displayed the lowest values. When comparing the fracture load of recent lithium disilicate ceramic material to the e.max group, which acted as the control, significant differences were noted. The LiSi Block GC group, in particular, had considerably higher mean difference values (208.867, p < 0.001, 95% CI [89.63, 328.10]), as did the Amber Mill group (164.200, p = 0.002, 95% CI [44.96, 283.44]) and CEREC Tessera group (137.533, p = 0.016, 95% CI [18.30, 256.77]). The e.max and n!ce Straumann groups had no statistically significant differences in mean scores (92.933, p = 0.198, 95% CI [-26.30, 212.17]). These findings imply that the clinical performance of recent lithium disilicate veneers varies when compared to the e.max CAD group. The fracture load of chairside CAD-CAM lithium disilicate veneers for maxillary central incisors varies according to the type of ceramic brands. Conventional pre-crystallized e.max CAD displayed higher fracture load than the recent pre- and fully-crystallized lithium disilicate materials, emphasizing the significance of choosing the right product based on the desired clinical outcome.

Two-Year Functional Outcomes of Nonsurgical Treatment in Concomitant Anterior Cruciate Ligament and Medial Collateral Ligament Injuries: A Case-Control Study.

The anterior cruciate ligament (ACL) is a common knee injury in high-intensity sports, which can cause early career loss in young athletes. Concomitant damage to other knee stabilizers may occur, such as the medial collateral ligament (MCL). Recent studies have shown that knee stability can increase without surgical intervention in patients with ACL and MCL injuries. Regarding the importance of functional tests in return to exercise prediction, this study aims to measure nonsurgical approach's long-term outcome for concomitant ACL and MCL injuries with a focus on functional tests. This is a case-control study with a 2-year follow-up. The case group consisted of patients who had provided written consent and completed their 2-year follow-up, and the control group was made up of healthy people who did not have any knee medical conditions and were matched by age, gender, and activity level. Physical examinations, Tegner and International Knee Documentation Committee questionnaires, and knee magnetic resonance imaging were conducted, and functional performance tests were performed after a 10-minute warm-up. Lody's index (the ratio of injured-to-uninjured knee results) was calculated. The data were analyzed using independent t-test, one-way analysis of variance, chi-squared test, and Fisher's exact test. The study involved 11 patients in each concomitant ACL and MCL injury cases and healthy control groups with a mean age of 32.4 and 28 years, respectively. None of the patients reported knee instability symptoms in the 2-year follow-up. More than half of the patients continued their sports field without reinjury, with no significant difference in activity levels between case and control groups. The 6-meter hop test and single-leg hop test showed no significant difference between case and control groups (p-value: 0.326, 0.859), and no significant difference was observed in the three Carioca, cocontraction, and Shuttle tests in the 2-year follow-up. Functional tests in ACL and MCL injuries revealed normal outcomes, implying a nonsurgical approach for patients with proximal ACL tears, better knee stability, and no significant differences between the injured and control groups.
