The Correlation between Small Placental Volume Measured by Three-dimensional Ultrasonography and Adverse Pregnancy Outcomes: An Observational Study

Objective: The placenta is a vital organ in the growth and development of fetuses within the uterus. The size of the placenta is positively associated with fetal well-being. The aim of this study was to investigate any potential correlation between placental volume and negative pregnancy outcomes. Materials and Methods: This prospective cohort study was conducted at the department of obstetrics and gynecology, Bhumibol Adulyadej Hospital, Thailand between October 2023 and February 2024. Subjects were singleton pregnant women ever the age of 18 without underlying diseases, namely: diabetes mellitus, hypertension, and autoimmune diseases. Ultrasonography was performed between the gestational ages of 28 and 36 weeks. Placental volume was measured via 3-dimensional ultrasonography and analyzed with maternal and neonatal outcomes. Results: A total of 132 participants were recruited. The mean age of participants was 28.6 years old. The abnormal (AV) and normal (NV) placental volume groups consisted of 14 and 118 cases, respectively. The AV group was older, with higher parity, cesarean delivery rate, and estimated blood loss. This group’s newborns had lower Apgar scores rated at 1 and 5 minutes and more neonatal complications than the NV group (with statistical significance). Maternal age exceeding 34 years could also be used to predict abnormal placental volume with sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) at percentages of 57.1, 81.4, 26.7 and 94.1, respectively. Conclusion: There is a correlation between placental volume abnormality and certainly adverse outcomes for newborns. Maternal age greater than 34 is associated with higher occurrence of placental volume abnormality.

Anti-atrial Fibrillatory and Cardiorenal Protective Effects of the Combination of Valsartan and Cilnidipine in Dahl Salt-Sensitive Rats.

The current study aimed to investigate the anti-atrial fibrillatory (AF) effects of a combination of valsartan and a calcium channel blocker (cilnidipine or amlodipine) in Dahl salt-sensitive (Dahl S) rats. Seven-week-old male Dahl S rats were fed an 8% salt diet. Six weeks later, valsartan (60 mg/kg, Val group), cilnidipine + valsartan (10 + 60 mg/kg, CV group), amlodipine + valsartan (3 + 60 mg/kg, AV group), or vehicle was orally administered daily for 5 weeks. Echocardiography and atrial electrophysiological evaluations were performed on the last day of treatment. Blood pressure in each drug treatment group was lower than in the Vehicle group. The duration of AF induced by atrial burst stimulation was shorter in the Val group (3.2 ± 1.6 s) than in the Vehicle group (11.2 ± 6.0 s), which was further shortened in the CV and AV groups (1.1 ± 0.3 and 1.3 ± 0.3 s, respectively). Left ventricular ejection fraction and left ventricular fractional shortening were greater in the CV and AV groups than those in the Vehicle group. Urinary albumin excretion in the CV group was the lowest among the drug-treated groups. The results collectively suggest that the combination of a calcium channel blocker with valsartan could be useful in terms of its anti-AF action as well as for improving cardiac and renal functions.

Креативные индустрии в муниципальных и региональных стратегиях Ивановской области и Краснодарского края

A methodology has been developed to assess the level of reflection of the topic of creative industries (CI) in municipal and regional strategies, tested in two regional (Ivanovo region and Krasnodar Territory) and ten municipal strategies (Krasnodar, Anapa, Gelendzhik, Novorossiysk, Tuapse and Ivanovo, Vichuga, Palekh, Privolzhsk , Shuya). The methodology provides for scoring the strategy text based on five characteristics: mention of the term CI; mention of activities related to CI; level of elaboration of the CI topic; attention to the types of activities included in the CI; availability of target indicators for CI. The strategy of the Krasnodar Territory and its municipalities, especially Anapa, Tuapse and Krasnodar, received high marks. In the Ivanovo region, only the strategies of Ivanovo and the region have good ratings. The remaining municipal strategies did not score even half of the possible points. Additionally, assessments of the objective level of CI development and the level of reflection of the CI theme in strategies were compared. The level of reflection of the CI topic in strategies is influenced by two factors: 1) the qualifications of the developers, their familiarity with the CI topic; 2) the objective significance of CI for the development of the city (region). The coincidence of both factors in the case of the Krasnodar Territory and its municipal district led to high estimates. Here the strategies were developed with the participation of a highly professional team of the Leontief Center Consortium - AV Group. The municipal district of Ivanovo region, significantly smaller in size and economic potential, could not afford to attract consultants, so the assessment of the level of development of CI is ahead of the assessment of the reflection of the topic in CI in the strategies of Palekh and Shuya. Recommendations are given on ways to strengthen the elaboration of the topic of CI in strategies.

An exploration of the relationship between loneliness, the severity of eating disorder-related symptoms and the experience of the 'anorexic voice'.

Many individuals with eating disorders (EDs) report the experience of an 'Anorexic voice' (AV). Negative experiences of loneliness are also often associated with EDs. This study sought to explore the relationship between experiences of loneliness, the frequency of the AV and the impact of this on ED symptom severity. 165 individuals (mean age 27.54 years) who accessed online forums relating to EDs participated in this study. The sample included individuals who have experienced an AV [AV group (N = 141)] and those who have not [non-AV group (N = 23)]. The study utilised self-report measures via an online questionnaire to explore the predictive validity of loneliness and frequency of the AV on ED symptom severity. Confirmatory analysis (AV group only) demonstrated the significance of the independent variables individually predicting ED symptom severity. However, a significant interaction was not found between the two primary variables in predicting ED symptom severity, more significantly than the influence of either variable alone. Exploratory analysis considered the differences between the two groups (AV and Non-AV), as well as considering alternate predictors. The findings offer insight into possible drivers behind engagement with the AV, as part of ED presentations in the community.

Outcomes of leadless pacemaker implantation after cardiac surgery and transcatheter structural valve interventions.

Permanent pacing indications are common after cardiac surgery and transcatheter structural valve interventions. Leadless pacemakers (LPs) have emerged as a useful alternative to transvenous pacemakers. However, current commercially available LPs are unable to provide atrial pacing or cardiac resynchronization and relatively little is known about LP outcomes after cardiac surgery and transcatheter valve interventions. This retrospective study included patients who received a Micra VR (MicraTM MC1VR01) or Micra AV (MicraTM MC1AVR1) (Medtronic) leadless pacemaker following cardiac surgery or transcatheter structural valve intervention between September 2014 and September 2022. Device performance and clinical outcomes, including ventricular pacing burden, ejection fraction, and need for conversion to transvenous pacing systems, were evaluated during follow-up. A total of 78 patients were included, of whom 40 received a Micra VR LP implant, and 38 received a Micra AV LP implant. The mean age of the cohort was 65.9 ± 17.9 years, and 48.1% were females. The follow-up duration for the entire cohort was 1.3 ± 1.1 years: 1.6 ± 1.3 years for the Micra VR group and 0.8 ± 0.5 years for the Micra AV group. Among the cohort, 50 patients had undergone cardiac surgery and 28 underwent transcatheter structural valve interventions. Device electrical performance was excellent during follow-up, with a small but clinically insignificant increase in ventricular pacing threshold and a slight decrease in pacing impedance. The mean right ventricle pacing (RVP) burden significantly decreased over time in the entire cohort (74.3% ± 37.2% postprocedure vs. 47.7% ± 40.6% at last follow-up, p < .001), and left ventricle ejection fraction (LVEF) showed a modest but significant downward trend during follow-up (55.0% ± 10.6% vs. 51.5% ± 11.2% p < .001). Patients with Micra VR implants had significantly reduced LVEF during follow-up (54.1% ± 11.9% vs. 48.8% ± 11.9%, p = .003), whereas LVEF appeared stable in the Micra AV group during follow-up (56.1% ± 9.0% vs. 54.6% ± 9.7%, p = .06). Six patients (7.7%) required conversion to transvenous pacing systems, four who required cardiac resynchronization for drop in LVEF with high RVP burden and two who required dual-chamber pacemakers for symptomatic sinus node dysfunction. Leadless pacemakers provide a useful alternative to transvenous pacemakers in appropriately selected patients after cardiac surgery and transcatheter structural valve interventions. Device performance is excellent over medium-term follow-up. However, a significant minority of patients require conversion to transvenous pacing systems for cardiac resynchronization or atrial pacing support, demonstrating the need for close electrophysiologic follow-up in this cohort.

Anti-inflammatory effects of banana (Musa balbisiana) peel extract on acne vulgaris: In vivo and in silico study

ObjectiveAcne vulgaris (AV) is a common problem with a relatively high incidence rate among Asian people. The potential antimicrobial and anti-inflammatory properties of banana peels have been demonstrated in previous studies but have not been studied in cases of AV. Therefore, this study was aimed at investigating the protective effects of banana (Musa balbisiana) peel extract (MBPE) against AV. MethodsThirty rats were divided into five groups (n = 6 rats per group): an AV group, AV group treated with 0.15% MBPE, AV group administered 0.30% MBPE, AV group administered 0.60% MBPE, and AV group administered clindamycin (the standard drug treatment). We assessed nodule size, bacterial count, histopathology, and cytokine levels (IL-1α, IFN-γ, tumor necrosis factor (TNF)-α, and IL-8). Enzyme linked immunoassays were used to measure the cytokine levels. In addition, we performed molecular docking studies to determine the interactions between phytochemicals (trigonelline, vanillin, ferulic acid, isovanillic acid, rutin, and salsolinol) via the Toll-like receptor 2 (TLR2) and nuclear factor-kappa B (NF-κB) pathways. ResultsAll MBPE treatment groups, compared with the AV group, showed suppression of both bacterial growth and proinflammatory cytokine production, as well as resolved tissue inflammation. The nodule size was significantly suppressed in the groups receiving the two highest doses of MBPE, compared with the AV group. However, the pharmacological action of MBPE remained inferior to that of clindamycin. Docking studies demonstrated that rutin was the phytocompound with the most negative interaction energy with TLR2 or NF-κB. ConclusionsOur results indicated that MBPE has anti-inflammatory effects against AV, by suppressing nodule formation, inhibiting bacterial growth, and decreasing proinflammatory cytokine production.

Comparison of first- and second-generation leadless pacemakers in patients with sinus rhythm and complete atrioventricular block.

The efficacy and safety of leadless cardiac pacemakers (LPMs) as an alternative to conventional transvenous cardiac pacing have been largely reported. The first generation of the MicraTM transcatheter pacing system (VR; Medtronic) was able to provide single-chamber VVI(R) pacing mode only, with a potential risk of pacemaker syndrome in sinus rhythm patients. A second-generation system (AV) now provides atrioventricular synchrony through atrial mechanical (Am) sensing capability (VDD mode). We sought to compare VR and AV systems in sinus rhythm patients with chronic ventricular pacing (Vp) for complete atrioventricular block. All consecutive patients implanted with an LPM in our department for complete atrioventricular block were retrospectively screened. Patients with atrial fibrillation, sinus dysfunction, or Vp burden <20% at 1 month postimplantation were excluded. Patients were systematically followed with a visit at 1 month, and then at least once a year. A total of 93 patients-45 VR (2015-2020) and 48 AV (2020-2021)-were included. VR and AV patients had similar baseline characteristics, except for VR patients being older (80 ± 8 vs. 77 ± 9 years, p = 0.049). The mean Vp burden was 77% in the VR and 82% in the AV group (p = 0.38). In AV patients, the median AV synchronous beats rate was 78%, with 65% having a >66% rate. An E/A ratio <1.2 as measured on echocardiography was the only independent predictor of accurate atrial mechanical tracking (p = 0.01). One-year survival rate was similar in both groups. Five patients in the VR and 0 in the AV group eventually developed pacemaker syndrome within 1 year post-implantation (p = 0.02). In sinus rhythm patients with chronic Vp for complete atrioventricular block implanted with an LPM, the atrial mechanical sensing algorithm allowed significant atrioventricular synchrony in most patients and was associated with no occurrence of-otherwise rare-pacemaker syndrome.

Comparison of 1st and 2nd generation leadless pacemaker in sinus rhythm patients with chronic ventricular pacing for complete atrioventricular block

Abstract Funding Acknowledgements Type of funding sources: None. Background Leadless pacemakers (LPMs) represent a seductive alternative to conventional pacing. First generation of Micra transcatheter pacing system was able to provide single-chamber VVI(R) pacing mode only, with a potential risk of pacemaker syndrome in sinus rhythm patients. A 2nd generation system (AV) now provides atrioventricular synchrony through atrial mechanical sensing capability (VDD mode). Purpose We sought to compare VR and AV systems in patients with sinus rhythm and chronic ventricular pacing for complete atrioventricular block. Methods All consecutive patients implanted with an LPM in our department for complete atrioventricular block were retrospectively screened. Patients with atrial fibrillation, sinus dysfunction, or ventricular pacing burden &amp;lt;20% at 1-month post-implantation were excluded. Results A total of 80 patients – 35 VR (2015-2020) and 45 AV (2020-2021) – were included. VR and AV patients had similar baseline characteristics, except for that VR patients being older (82±8 versus 77±9 years, p=0.01). Mean ventricular pacing burden was 75% in the VR and 79% in the AV group (p=0.63). In AV patients, median atrioventricular synchronous beats rate was 77%, 67% having a &amp;gt;66% rate. An E/A ratio &amp;lt;1 as measured on echocardiography was the only independent predictor of accurate atrial mechanical tracking (adjusted OR=13, p=0.006). One-year survival rate was 86% in the VR group and 95% in the AV group (adjusted p=0.21). Two patients in the VR and 0 in the AV group eventually developed pacemaker syndrome in the 1st year post-implantation (p=0.07). Conclusion In sinus rhythm patients with chronic ventricular pacing for complete atrioventricular block implanted with an LPM, atrial mechanical sensing algorithm allowed significant atrioventricular synchrony in most patients, and was associated with no occurrence of – otherwise rare – pacemaker syndrome.

Construction and efficacy of Aeromonas veronii mutant Δhcp as a live attenuated vaccine for the largemouth bass (Micropterus salmoides)

Aeromonas veronii is a human and animal co-pathogenic bacterium that could have a significant negative impact on both human health and aquaculture. In this study, a mutant strain of A. veronii with deletion of the hemolysin co-regulated protein (hcp) gene was constructed (Δhcp-AV). Compared with the wild strain, Δhcp-AV showed significantly reduced growth capacity and biofilm formation ability. Motility tests showed that the hcp gene had no significant effect on the swimming and swarming ability. In addition, the pathogenicity was also reduced. To evaluate the efficacy of Δhcp-AV as a live attenuated vaccine for prevention of Aeromonas veronii infection, we compared the immune response of largemouth bass (Micropterus salmoides) after immunization with 500 μL of 1.47 × 105 CFU/mL of Δhcp-AV and 4 × 108 CFU/mL of inactivated A. veronii. Obvious increases of serum immune related enzyme activity were observed in immunization groups. Expression levels of immune-related genes in Δhcp-AV group were up-regulated, and higher than those in inactivated A. veronii group. After challenging with live A. veronii, the relative percent survival (RPS) was 100% in Δhcp- AV group, whereas the RPS was 76.67% in inactivated A. veronii group. Our data suggest that the live attenuated vaccine Δhcp- AV could elicit a stronger immune response and provide a higher RPS than inactivated A. veronii. These data suggest that hcp gene is an important virulence factor of A. veronii, and the live attenuated vaccine Δhcp-AV is safe and effective for prevention A. veronii infection in M. salmoides farming.

Whole body vibration activates AMPK/CPT1 signaling pathway of skeletal muscle in young and aging mice based on metabolomics study.

Whole-body vibration (WBV) can improve skeletal muscle function in aging mice, but whether the effect on young and aging skeletal muscle is consistent has not been studied. We selected C57BL/6J mouse models, which were divided into young control group (YC), young vibration group (YV), aging control group (AC) and aging vibration group (AV). After 12 weeks of WBV, we found that compared with the YC group, the pathways of linoleic acid metabolism, biosynthesis of unsaturated fatty acids, arachidonic acid metabolism, nicotinate and nicotinamide metabolism, glycine, serine and threonine metabolism, and arginine and proline metabolism improved significantly in the YV group. Compared with the AC group, the pathways of arachidonic acid metabolism, alpha-linolenic acid metabolism, biosynthesis of unsaturated fatty acids, pentose and glucuronate interconversions and pentose phosphate pathway improved significantly in the AV group. Furthermore, we found that WBV decreased triglyceride (TG), total cholesterol (TC), and free fatty acid (FFA) levels in aging mice, improved mitochondrial membrane potential, and increased the expression of phosphorylated activated protein kinase (p-AMPK), peroxisome proliferator-activated receptor coactivator-1α (PGC-1α) and carnitine palmitoyl transferase 1B (CPT1B) in the skeletal muscle of young and aging mice. Our study revealed that WBV mainly improved lipid metabolism and amino acid metabolism pathways of skeletal muscle in young mice and mainly improved lipid metabolism and glucose metabolism pathways of skeletal muscle in aging mice. WBV can activate the AMPK/CPT1 signaling pathway and improve mitochondrial function in skeletal muscle in both young and aging mice.

Assessment of Serum Level of VASPIN in Acne Patients

Background: Acne vulgaris is a prevalent chronic skin condition with pilosebaceous blockages and/or inflammation (hair follicles and their accompanying sebaceous gland). Aim: to investigate vaspin levels in serum of acne sufferers in comparison with normal controls and to link their levels with the severity of the illness. Methods: 30 instances of AV and 31 healthy control groups have been examined and each patient has been submitted to comprehensive history; complete clinical examination and levels of serum vaspine were calculated. Methods: Results: The level of vaspin was much greater in the AV group than the control group (medium=2785.2 vs 155.4 against p < 0.001). For discriminating between AV patients and control groups, the Vaspin level receiver operating characteristic curve (ROC) has been performed. Vaspin exhibited o.989 AUC. At a cut-off of 212.2, sensitivity was 96.7%, the specificity of 96.8%, 96.7%, NPV was 96.7% and the accuracy of 96.8%. ROC Vaspin-level curve has been performed for discriminating between mild to moderate and severe AV patients. Vaspin exhibited o.93o AUC. At a cut-off value of 3,911.5, sensitivity was 9%, the specificity was 9%, PPV was 81.8%, NPV was 94.7%, and accuracy was 9%. Conclusion: The level of Vaspin in the AV group was considerably greater than that of the control group with 96.7% susceptibility and 96.8% characteristics. Adipose and severity of AV were linked substantially with a greater vaspin level; the Vaspin level was proposed as a separate AV susceptibility and severity predictor.

Comparison between selective caudal fixed screw construct and all variable screw construct in anterior cervical discectomy and fusion

This retrospective comparative study aimed to compare the efficacy of selective caudal fixed screw constructs with all variable screw constructs in anterior cervical discectomy and fusion (ACDF). Thirty-five patients who underwent surgery using selective caudal fixed screw construct (SF group) were compared with 44 patients who underwent surgery using all variable constructs (AV group). The fusion rate, subsidence, adjacent level ossification development (ALOD), adjacent segmental disease (ASD), and plate-adjacent disc space distance were assessed. The one-year fusion rates assessed by computed tomography bone bridging and interspinous motion as well as the significant subsidence rate did not differ significantly between the AV and SF groups. The ALOD and ASD rates and plate-adjacent disc space distances did not significantly differ between the two groups at both the cranial and caudal adjacent levels. The number of operated levels was significantly associated with pseudarthrosis in the logistic regression analysis. The stability provided by the locking mechanism of the fixed screw did not lead to an increased fusion rate at the caudal level. Therefore, the screw type should be selected based on individual patient’s anatomy and surgeon’s experience without concern for increased complications caused by screw type.

Study of Serum Calprotectin Level in Patients with Acne Vulgaris and its Correlation to Disease Severity

Acne vulgaris is a common skin condition that affects people all over the world. Acne vulgaris is characterised by the presence of open and closed comedones, papules, pustules, and nodules on areas of the body with hormonally sensitive sebaceous glands. Acne is thought to be caused by four key factors: increased sebum production, follicular hyperkeratinization, skin bacterial colonisation, and inflammation. Acne with severe symptoms is painful, disfiguring, scarring, and lowering self-esteem. The aim of this study was to determine the serum level of calprotectin in acne vulgaris patients and its relationship to disease severity. Subjects and Methods: In this sample, 60 people with acne vulgaris were paired with 30 people who appeared to be of similar sex and age as a control group. The patients were chosen from those who attended the Benha University Hospital's Dermatology and Andrology Department's Outpatient Clinic between April 2019 and October 2020. Our findings indicated that the AV group had a statistically significant higher level of serum calprotectin with mean SD (6.291.91ng/dl) than the control group with mean SD (2.040.65ng/dl) (p=0.004). The amount of serum calprotectin had a statistically significant positive relationship with the GAGS score (r=0.854; p0.001). The period of the disease, however, had no meaningful correlation (r=0.163;p=0.212). Conclusion: Serum calprotectin levels are higher in acne vulgaris patients relative to safe controls, and there is a statistically significant relationship between calprotectin levels and disease severity, suggesting that calprotectin may be used as a chemical biomarker to determine disease severity.

Immunomodulatory Effect of Virgin Coconut Oil in Wistar Rats Infected with Staphylococcus aureus

&lt;p class="abstrak1"&gt;Virgin coconut oil (VCO) contains bioactive that induce immunity against infectious diseases. This study aim to determine the immunomodulatory effects of VCO based on the activity of superoxide dismutase (SOD), lymphocyte proliferation, and histopathological examination in liver and kidney of rats infected with &lt;em&gt;Staphylococcus&lt;/em&gt; &lt;em&gt;aureus&lt;/em&gt;. The VCO was given intragastrically to rats with a dose of 250 µL for one week. The rats were infected with &lt;em&gt;S. aureus&lt;/em&gt; at 5x10&lt;sup&gt;2&lt;/sup&gt; bacterial cells intraperitoneally. Twenty (20) female &lt;em&gt;Wistar&lt;/em&gt; rats of one month old were divided into four groups. The negative control group (C-): without treatment, AV group: infected with &lt;em&gt;S. aureus&lt;/em&gt; followed by VCO treatment; VA group: pretreated with VCO followed by &lt;em&gt;S. aureus &lt;/em&gt;infection, and positive control group (C+): were infected with &lt;em&gt;S. aureus&lt;/em&gt; without VCO. All rats were euthanized and necropsied based on the animal ethic standard. Plasma samples were taken to evaluate SOD activity, and lymphocytes were isolated from the spleen to determine their proliferative ability. Livers and kidneys were collected for a histopathology examination. Results showed that the VA group had the highest SOD activity on the 4&lt;sup&gt;th&lt;/sup&gt; week (41.50 ± 3.56 %) and lymphocyte proliferation (0.3018) compared to all treatments, indicating immunomodulatory effects of VCO. Liver of treatments group showed leucocytes infiltration, no hemorrhages (VA); the hepatocytes with normal cells (VA). Kidney of treatments group showed leucocytes infiltration (AV); normal epithelial glomerulus and tubulus cells, still found hemorrhage (VA). These studies indicated that VCO has a potential role as an immunomodulator, hepatoprotectant, and nephroprotectant.&lt;/p&gt;

Protective Effect of Hydroalcoholic Extract of Aloe Vera Supplemented by Zinc on the Testis of Wistar Albino Rats Exposed to Cadmium

Infertility is a major health concern that may be caused due to inadequate fertility hormones or poor quality of reproductive parameters. The environmental pollutants such as cadmium is one of the causative factors for inducing infertility in men. Cadmium accumulates in various tissues and affects reproductive organs, especially testis which is highly sensitive to cadmium poisoning. In this experiment, protective effect of hydroalcoholic extract (HAE) of Aloe vera with and without zinc has been evaluated. Zinc, protects the testes from damages resulting due to cadmium. Aloe vera is a very good source of antioxidants such as vitamin C and E. In this experiment male Wistar albino rats were grouped into 5. The control group received only the vehicle. Experimental groups were administered in Cd group with 10mg/Kg body weight of CdCl2, in Cd+Zn group 40mg/Kg body weight of CdCl2 and 40mg/Kg bodyweight of ZnCl2, in Cd+AV group 10mg/Kg body weight of CdCl2 and 200mg/Kg body weight of HAE of Aloe vera and in Cd+AV+Zn 10mg/Kg body weight of CdCl2, 200mg/Kg body weight of HAE of Aloe vera and 40mg/Kg bodyweight of ZnCl2. The results showed that cadmium caused extensive testicular damage which was protected by HAE of Aloe vera and zinc. Hence, protective effect of HAE of Aloe vera was exhibited clearly in cadmium treated rats, however, supplementing Aloe vera with zinc provided better protection.

Auditory but Not Audiovisual Cues Lead to Higher Neural Sensitivity to the Statistical Regularities of an Unfamiliar Musical Style.

It is still a matter of debate whether visual aids improve learning of music. In a multisession study, we investigated the neural signatures of novel music sequence learning with or without aids (auditory-only: AO, audiovisual: AV). During three training sessions on three separate days, participants (nonmusicians) reproduced (note by note on a keyboard) melodic sequences generated by an artificial musical grammar. The AV group (n = 20) had each note color-coded on screen, whereas the AO group (n = 20) had no color indication. We evaluated learning of the statistical regularities of the novel music grammar before and after training by presenting melodies ending on correct or incorrect notes and by asking participants to judge the correctness and surprisal of the final note, while EEG was recorded. We found that participants successfully learned the new grammar. Although the AV group, as compared to the AO group, reproduced longer sequences during training, there was no significant difference in learning between groups. At the neural level, after training, the AO group showed a larger N100 response to low-probability compared with high-probability notes, suggesting an increased neural sensitivity to statistical properties of the grammar; this effect was not observed in the AV group. Our findings indicate that visual aids might improve sequence reproduction while not necessarily promoting better learning, indicating a potential dissociation between sequence reproduction and learning. We suggest that the difficulty induced by auditory-only input during music training might enhance cognitive engagement, thereby improving neural sensitivity to the underlying statistical properties of the learned material.

Ischemic Modified Albumin as A Biomarker in Predicting Oxidative Stress in Patients With Acne Vulgaris

Acne vulgaris is a cutaneous chronic inflammatory disorder with complex pathogenesis. The aim of this study was to evaluate the serum level of IMA in patients with AV to evaluate its role in AV pathogenesis and its possible relation with oxidative stress markers in the disease.This study was conducted as a case-control study and was conducted on 30 patients suffering from AV (Group A) and 18 apparently healthy individuals of matched age and sex as a control group (Group B). All studied subjects were tested for Serum level of Ischemia modified albumin (IMA), Serum level of Glutathione-S-Transferase (GST), Serum level of Catalase (CAT) and Serum level of Malondialdehyde (MDA). Serum IMA showed significant positive correlation with GAGS, GSH, MDA and significant negative correlation with CAT. AV grades showed significant positive correlation with GSH, MDA, IMA and significant negative correlation with CAT. No significant correlations were found in IMA with age and duration in AV group Serum IMA then MDA, GSH and CAT might play a role in AV pathogenesis. Moreover, its serum levels could be considered as independent predictor of AV susceptibility, activity and severity.

Association between Satisfaction with Life and Personality Types A and D in Young Women with Acne Vulgaris.

People with acne vulgaris report a lower level of satisfaction with life and are more frequently classified as having Type D personalities than those without acne. This research examined, for the first time, the moderating and mediating role of personality type in the relationship between acne severity and satisfaction with life. Among 300 female nursing and cosmetology students ranging in age from 19 to 24 years (M = 21.28, SD = 1.39), 150 individuals (50%) presented with symptoms of acne vulgaris (AV group), while the other 150 (50%) were categorized as controls without acne vulgaris (WAV sample). A cross-sectional study was conducted using three self-report questionnaires: The Satisfaction with Life Scale (SWLS), the Framingham Type A Scale (FTAS), and the Type D Scale (DS14). Acne vulgaris was clinically diagnosed using the Hellgren–Vincent Scale (HVS). The AV group scored significantly higher on the FTAS and DS14 and lower on the SWLS than the WAV sample. Life satisfaction correlated negatively with both the negative affectivity (NA) and social inhibition (SI) subscales of the DS14. The moderating role of the Type A behavioral pattern (TABP) and the mediating role of both NA and SI subscales of the DS14 were observed in the relationship between acne severity and satisfaction with life. The type of personality may explain the mechanism of the relationship between acne disease and subjective well-being.
