Effect of rest duration between sets on fatigue and recovery after short intense plyometric exercise

Plyometric training is characterized by high-intensity exercise which is performed in short term efforts divided into sets. The purpose of the present study was twofold: first, to investigate the effects of three distinct plyometric exercise protocols, each with varying work-to-rest ratios, on muscle fatigue and recovery using an incline-plane training machine; and second, to assess the relationship between changes in lower limb muscle strength and power and the biochemical response to the three exercise variants employed. Forty-five adult males were randomly divided into 3 groups (n = 15) performing an exercise of 60 rebounds on an incline-plane training machine. The G0 group performed continuous exercise, while the G45 and G90 groups completed 4 sets of 15 repetitions, each set lasting 45 s with 45 s rest in G45 (work-to-rest ratio of 1:1) and 90 s rest in G90 (1:2 ratio). Changes in muscle torques of knee extensors and flexors, as well as blood lactate (LA) and ammonia levels, were assessed before and every 5 min for 30 min after completing the workout. The results showed significantly higher (p < 0.001) average power across all jumps generated during intermittent compared to continuous exercise. The greatest decrease in knee extensor strength immediately post-exercise was recorded in group G0 and the least in G90. The post-exercise time course of LA changes followed a similar pattern in all groups, while the longer the interval between sets, the faster LA returned to baseline. Intermittent exercise had a more favourable effect on muscle energy metabolism and recovery than continuous exercise, and the work-to-rest ratio of 1:2 in plyometric exercises was sufficient rest time to allow the continuation of exercise in subsequent sets at similar intensity.

The Protective Role of Nigela Sativa Volatile Oil on Antioxidant and Oxidative Stress Enzymes

Hepatotoxicity is the outcome of a paracetamol overdose.In this study, 40 adult male rats, weighing 180–260 gm and aged between 9 and 13 weeks, were given doses of Nigela sativa oil and their liver enzymes were examined to see how paracetamol affected them. The rats were kept in an environment at a temperature of 25 Co in an animal house. ,There were four groups of rats, and food was provided for them. (G). (G1) The only injections given to the control group are food and regular saline (0.9% of the time). (G2) 200 mg/kg of N. sativa and (G3) 400 mg/kg of paracetamol Addition of 400 mg/kg body weight of paracetamol. supplying 300 mg/kg B.W. of N. sativa to (G4)400 milligrams/kg B.W. of aspirin. Rat G2, GPT 87.80 IUL, and GOT hepatic enzyme concentration (129.32 IUL) all exhibit significant increases in comparison to the control. Furthermore, the levels of the liver GSH enzyme in rats (G2 )1.24 IUL shown a substantial increase, whereas G3 ( GOT ) 91.9 IUL, (GPT )76.70 IUL, and group (G4) GOT 109.88 IUL and enzyme (GPT ) 55.66 IUL exhibited significant declines as compared with control. While MDA enzyme in rats G2 (0.259 IUL) shows a major increase in comparison to the control, rats G3 (0.139 IUL) and G4 (0.112) show a noticeable decrease in comparison to G2. While body weight indicates that G2's outcomes are significantly lower than those of the other three groups. Groups G3 (2.55 gm) and G4 (2.7 gm) demonstrated a significant rise in liver weight compared to controls and G2, whereas groups G2 (24.23 gm) demonstrated a significant increase in liver weight compared to controls and group G2. Male rats in groups G2 (1.7 gm) demonstrated a significant drop in liver weight compared to controls.

The effect of the HMGB1/RAGE/TLR4/NF-κB signalling pathway in patients with idiopathic epilepsy and its relationship with toxoplasmosis.

This study aims to investigate the relationship between toxoplasmosis and this pathway, which may be effective in the formation of epilepsy by acting through the HMGB1/RAGE/TLR4/NF-κB signalling pathway in patients with idiopathic epilepsy. In the study, four different experimental groups were formed by selecting Toxoplasma gondii IgG positive and negative patients with idiopathic epilepsy and healthy controls. Experimental groups were as follows: Group 1: Epilepsy+/Toxo- (E+, T-) (n = 10), Group 2: Epilepsy-/Toxo- (E-, T-) (n = 10), Group 3: Epilepsy-/Toxo+ (E-, T+) (n = 10), Group 4: Epilepsy+/Toxo+ (E+, T+) (n = 10). HMGB1, RAGE, TLR4, TLR1, TLR2, TLR3, IRAK1, IRAK2, IKBKB, IKBKG, BCL3, IL1β, IL10, 1 L8 and TNFα mRNA expression levels in the HMGB/RAGE/TLR4/NF-κB signalling pathway were determined by quantitative simultaneous PCR (qRT-PCR) after collecting blood samples from all patients in the groups. Statistical analysis was performed by one-way ANOVA followed by LSD post-hoc tests, and p < 0.05 was considered to denote statistical significance. The gene expression levels of HMGB1, TLR4, IL10, IL1B, IL8, and TLR2 were significantly higher in the G1 group than in the other groups (p < 0.05). In the G3 group, RAGE and BCL3 gene expression levels were significantly higher than in the other groups (p < 0.05). In the G4 group, however, IRAK2, IKBKB, and IKBKG gene expression levels were significantly higher than in the other groups (p < 0.05). HMGB1, TLR4, IRAK2, IKBKB, IL10, IL1B, IL1B, and IL8 in this signalling pathway are highly expressed in epilepsy patients in G1 and seizures occur with the stimulation of excitatory mechanisms by acting through this pathway. The signalling pathway in epilepsy may be activated by HMGB1, TLR4, and TLR2, which are considered to increase the level of proinflammatory cytokines. In T. gondii, this pathway is activated by RAGE and BCL3.

Impact of ginger powder (Zingiber officinale) supplementation on the performance, biochemical parameters, antioxidant status, and rumen fermentation in Ossimi rams.

Ginger (Zingiber officinale) has great potential as a growth promoter and immunostimulant in ruminant nutrition. This study assessed the impact of ginger powder supplementation on Ossimi rams' rumen fermentation, biochemical parameters, and antioxidant levels. Fifteen Ossimi rams, aged 10 ± 1.3 months and weighing 30 ± 1.5 kg. Rams were randomly divided into three experimental groups: The control group (G1) received standard feed, while ginger powder (5 g and 7 g/kg body weight [BW] for G2 and G3, respectively) mixed in water was administered to groups G2 and G3 before their standard feed. The control group recorded higher dry matter (DM) intake values (p < 0.05) than the ginger-treated groups. The ginger-treated groups showed superiority (p < 0.05) in weight gain and feed conversion compared to the control group. The digestion coefficients of DM, crude protein, and crude fiber were significantly (p < 0.05) increased by a high dose (7 g/Kg BW) of ginger supplementation, whereas organic matter, ether extract, and nitrogen-free extract digestibility remained unchanged. Compared to the control group, the rams given 5 g of ginger had significantly less (p < 0.05) total protein and globulin in their serum, but the rams given 7 g of ginger had significantly more (p < 0.05) of these proteins. In the ginger groups, these levels were significantly (p < 0.01) lower than those in the control group for serum creatinine, uric acid, urea, total lipids, triglycerides, total cholesterol, glucose, serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and gamma-glutamyl transferase. Rams given ginger had significant growth hormone, insulin-like growth factor-1, total superoxide dismutase, GSH-Px, TAC, immunoglobulin (Ig) A, and IgG enhancement (p < 0.01), and a decrease (p < 0.01) in malondialdehyde concentration compared to the control group. Significant increases in total short-chain volatile fatty acids, acetic, propionic, and isovaleric acids (p < 0.05), and significant decreases in NH3N and protozoa (p < 0.01). Ginger powder (5 g and 7 g) can improve growth, immune responses, antioxidant status, and ruminal parameters in rams. Further study is needed to evaluate the effect of ginger on different types of animals (cow, buffalo, and goat) to develop new feed additives.

Modified method of producing sciatic nerve crush injury model in Wistar rats: A pilot study

The production of a standard and reproducible experimental mode of peripheral nerve injury, has been a long-time quest in nerve regeneration research. The aim of this pilot study was to reproduce sciatic nerve crush injury model in Wistar rats and also use the established method for broader and future research. Materials and Methods: twenty (20) rats grouped into five (5) of five (5) rats each. Normal control (G1), the sciatic was not exposed nor crushed; Sham (G2), the sciatic nerve were surgically exposed but not crushed; Crushed (G3), the sciatic nerve were surgically exposed and uniformly crushed, using a non-serrated heamostatic forceps that exerted a compressive force of 33N for a duration of 30 seconds and Transected (G4), the sciatic nerve were exposed and completely transected. Sciatic nerves were harvested at seven (7) days (post-injury) for histological evaluation and the groups were compared for histopathological changes. Results: Transverse sections of toluidine blue (TB) stained sciatic nerve micrograph, showed degenerative changes in the axons, myelin ballooning and surveiling white blood cells, all of which were consistent with Wallerian degeneration in G3, when compared with groups G1 and G2. The G4 group showed more severe degenerative changes when compared with group G3. Conclusion: The histopathological analysis suggest that the modified induction method used in this study, caused Axonotmetic lesion in the crushed sciatic nerves of the Wistar rats.

Therapeutic Effect of Avishan-e-Shirazi (Zataria Multiflora Boiss) Root Extract on Oxidative Stress Markers in Moderate Asthmatic Patients

Avishan-e-Shirazi (Zataria Multiflora Boiss) is a plant widely recognised for its medicinal and culinary purposes. Objectives: To evaluate the therapeutic effect of plant’s root extract on pulmonary function tests and oxidative stress markers among moderate Asthma tic patients. Methods: A total participant of 66 patients with pulmonary disease, 30-40 age, were selected for the 2-month research trial. Individuals were enrolled and distributed equally in two groups, 33 each. In the control group, 53.8% of individual were man, and 46.2% were women. In the treatment group, 49.1% of participants were man, and 50.9% were women. The groups G0 was considered as a control group with no root extract, and group G1 where conventional treatment and root extract were advised to participants. The participants were selected from the Jinnah Hospital, Pakistan. The 5mg/kg/day dried root extract supplements 3 times a day were given to the individuals daily for 2 months. Results: The mean age group of Asthma tic patients enrolled in the study was 35 ± 2.98 years in G0, and in G1, it was 34 ± 3.05. The mean BMI was 31.34 and 30.98 kgm-2 in both groups, respectively. There was a significant improvement in FEV1 levels and MDA enzyme levels with a p-value less than 0.05. The NO2 levels were also better. Similarly, the enzymes thiolase and SOD levels also improved with a p-value less than 0.05 in the treatment group. Conclusions: The current study concluded that Avishan-e-Shirazi root extract could improve the pulmonary function and inflammation among Asthma patients.

Evaluation of Mechanical Properties of Self-cured, Heat-cured, and Photosensitive 3D Printing Resins After the Addition of Silica Nanoparticles

This study evaluated investigate the addition of silica nanoparticles in autopolymerizable resin and into liquid resin for 3D printing and compare them with CAD-CAM blocks and thermopolymerizable resin, regarding flexural strength and surface roughness. Eight groups (n=12) were created according to the types of materials: autopolymerizable resin (G1-G4), photosensitive resin for 3D printing (G5-G6), PMMA block (G7) and thermopolymerizable resin (G8). Functionalized silica nanoparticles (0.5-1.5 wt%) were added in groups G2-G4 and G6. Mechanical flexural strength, surface roughness and morphological analysis were carried out to evaluate the properties of the samples. One-way ANOVA, followed by Tukey's post-hoc test, was used to evaluate the data. The average surface roughness was higher in group G7 and lower in the G8 group, with a statistical difference (p &lt; 0.001). The G8 and G1-G4 showed no significant difference in surface roughness. The G5 and G6 presented surface roughness higher than that recommended by Borchers and Bollen (Ra=0.2 µm). The incorporation of nanoparticles into self-polymerizing acrylic resins negatively affected the mechanical properties of the material, reducing flexural strength. The G5 and G6 demonstrated the lowest flexural strength (p&lt;0.001), presenting values lower than those recommended by ISO (σ &gt;60 MPa) regardless of the incorporation or not of silica nanoparticles. The G7 presented the highest flexural strength value followed by the G8. Within the limits of this study, it may be concluded that the addition of silica nanoparticles did not improve the flexural strength the G6 and also affected negatively the mechanical properties of self-polymerizing acrylic resins.

Effect of Age on Sexual Behaviour, Scrotal Circumference and Scrotal Surface Temperature in Sahiwal Bulls

Age of the bull influences the sexual behaviour and quality of semen. The present study was conducted to find out the age window at which the bull shows best reproductive performance. Fifteen Sahiwal bulls were selected and classified into three age groups (n=5, in each group) - G1(2- 3.5), G2 (&gt;3.5-8) and G3 (&gt;8-12) years. The sexual behaviour was recorded at the time of semen collection by CCTV camera at 15 days interval. Scrotal circumference (by scrotal tape) and scrotal surface temperature (by IRT) were also taken at monthly interval. The data so obtained in the experiment was subjected to statistical analysis by one-way analysis of variance (ANOVA) using SPSS software version 26.0 to draw scientific interferences. The results revealed that the mean value of scrotal circumference was significantly (p&lt;0.05) low in G1 as compared to the other two groups. No significant difference was observed among the groups for scrotal surface temperature and scrotal temperature gradient. Most of the sexual behaviour parameters were significantly high in the G2 (&gt;3.5-8) group except for the time to enter arena from preparation site and total number of mountings. Therefore, it can be concluded from this study that sexual behaviour is influenced by age and adult (middle) aged bulls performed better as compared to young and old groups.

Protein level alteration and micronuclei induction in Channa punctatus fish exposed to chlorpyrifos and their alleviation by Melissa officinalis and Mentha piperita extracts

Aim: To assess alteration in the protein levels of major organs and induction of micronuclei in the freshwater fish, Channa punctatus following exposure to chlorpyrifos, while also investigating the potential mitigating effects of extracts from Melissa officinalis and Mentha piperita on the adverse impacts induced by this pesticide. Methodology: Two weeks of acclimatized healthy fish were divided into four different groups. Group G1 served as the control group, while G2 contained chlorpyrifos (LC50/10, 96 hr). Group G3 was exposed to chlorpyrifos (LC50/10, 96 hr) along with 8 mg l-1 of Melissa officinalis ethanolic extract, and similarly, G4 contained chlorpyrifos (LC50/10, 96 hr) along with 8 mg l-1 ethanolic extract of Mentha piperita. Sampling was conducted over various durations of 7, 14, 21, and 28 days. The ethanolic extracts of Melissa officinalis and Mentha piperita were used as remedial compounds as they are rich in several bioactive compounds, primarily polyphenols. Results: The investigation revealed a notable decrease in the total protein content of kidney, liver, gills and muscles following exposure to chlorpyrifos after each sampling duration. While, upon exposure to remedies containing the ethanolic extracts of Melissa officinalis and Mentha piperita, the protein levels exhibited a significant recovery (p &lt; 0.05) in a duration-dependent manner, compared to the control group. This suggests a promising ameliorative capability of Melissa officinalis and Mentha piperita against chlorpyrifos toxicity. Further, the induction of micronuclei by chlorpyrifos and their subsequent recovery through the application of phytoextracts Melissa officinalis and Mentha piperita displayed a similar pattern, indicating the potential protective effects of these extracts against chlorpyrifos-induced genotoxicity. Interpretation: It is plausible to conclude that standardized doses of Melissa officinalis and Mentha piperita hold the potential to enhance aquaculture practices and safeguard fish production in agriculturally contaminated water bodies. These findings emphasize their valuable contribution in sustaining fish health amidst toxic environments. Key words: Channa punctatus, Chlorpyrifos, Melissa officinalis, Mentha piperita

Objectives: To identify some biochemical parameters that help predict LV remodelling after STEMI. By determining serum levels of Resisten and IL-6 in patients with ST-segment elevation MI (STEMI) and apparently healthy controls. Patients &amp; Methods: This prospective case-controlled study was conducted from beginning May 2023 to end of October 2023. This study was conducted on 110 individuals, including sixty-two patients (50 males and 12 females) who had undergone a STEMI and forty-eight healthy control subjects. The information about patients in this study was retrieved from patients' hospital records. The samples were collected from Azadi Teaching Hospital/ Kirkuk on patients with STEMI. Forty-eight of apparently healthy sex and age-matched controls were included in this study. The data were collected from the cases group as (G2) means: From the moment the patient arrives to internal resuscitation and up to 48 hours and at the baseline of the STEMI (ST elevation of the myocardial fraction), and (G3) means: After 4-6 months follow up, These states were also compared to the control group composed of (48) individuals who were apparently healthy. About five ml of blood was collected from the antecubital vein for both patients and healthy individuals in an anticoagulant tube to estimate the Resisten and IL-6 levels. Results: The results of the study showed that the serum level of resisten were significantly higher in group G2 (patients group) in comparison to those of the A1 (control group) P &lt;0.01. The current research demonstrated non-significant differences in IL-6 levels between (G1 and G2), while showing highly significant differences between A1 and A3; this was also applicable for G2 and G3. Conclusion: The current study concluded that there are significantly increasing of Resistin levels in patients in matching to control groups. Also, it was noticed that IL-6 mean concentration levels were lower in A2 in comparison to A1 but higher than in A3.

Exploring botulinum toxin’s impact on masseter hypertrophy: a randomized, triple-blinded clinical trial

The present study aimed to assess the effectiveness and functional adverse effects of a single and multiple injections of botulinum toxin A (BoNT-A) for masseter hypertrophy (MH). Twenty-six women complaining about lower third facial enlargement due to MH, received 75 U of BoNT-A (abobotulinum toxin) in each masseter muscles. After 3 months, patients were randomly assigned to receive a second treatment session of Saline Solution: (G1; n = 11) or BoNT-A: (G2; n = 12). Muscle thickness (ultrasound), electrical activity (electromyography; EMG), masticatory performance, and subjective perception of MH were evaluated. Follow-up was performed at 1, 3 and 6 months. Muscle thickness, EMG activity, and masticatory performance were analyzed using ANOVA two-way and Sidak test as post-hoc. Masticatory performance was analyzed by the Friedman’s test and Mann–Whitney test. Regarding inter-groups comparisons, there was a significant decrease in the left masseter muscle thickness in the G2 group at the 6 month follow-up (p < 0.02). For EMG, significant differences were evident at the 6 month assessment, with higher masseter activity for G1 (p < 0.05). For masticatory performance, no significant differences were observed throughout the study (p > 0.05) and a higher improvement in subjective perception of MH was observed in the 1 month follow-up for G2 (p < 0.05). In conclusion, BoNT-A is effective for MH, however multiple injections cause functional adverse effects in masseter muscle.

Genetic diversity of H5N1 and H5N2 high pathogenicity avian influenza viruses isolated from poultry in Japan during the winter of 2022–2023

High pathogenicity avian influenza viruses (HPAIVs) of the H5N1 and H5N2 subtypes were responsible for 84 HPAI outbreaks on poultry premises in Japan during October 2022–April 2023. The number of outbreaks during the winter of 2022–2023 is the largest ever reported in Japan. In this study, we performed phylogenetic analyses using the full genetic sequences of HPAIVs isolated in Japan during 2022–2023 and those obtained from a public database to identify their genetic origin. Based on the hemagglutinin genes, these HPAIVs were classified into the G2 group of clade 2.3.4.4b, whose ancestors were H5 HPAIVs that circulated in Europe in late 2020, and were then further divided into three subgroups (G2b, G2d, and G2c). Approximately one-third of these viruses were classified into the G2b and G2d groups, which also included H5N1 HPAIVs detected in Japan during 2021–2022. In contrast, the remaining two-thirds were classified into the G2c group, which originated from H5N1 HPAIVs isolated in Asian countries and Russia during the winter of 2021–2022. Unlike the G2b and G2d viruses, the G2c viruses were first detected in Japan in the fall of 2022. Importantly, G2c viruses caused the largest number of outbreaks throughout Japan over the longest period during the season. Phylogenetic analyses using eight segment genes revealed that G2b, G2d, and G2c viruses were divided into 2, 4, and 11 genotypes, respectively, because they have various internal genes closely related to those of avian influenza viruses detected in wild birds in recent years in Asia, Russia, and North America, respectively. These results suggest that HPAIVs were disseminated among migratory birds, which may have generated numerous reassortant viruses with various gene constellations, resulting in a considerable number of outbreaks during the winter of 2022–2023.

Optimizing Tilapia (Oreochromis niloticus) Growth through a Comparative Evaluation of EM4 and Homemade Probiotics in Pellets

One alternative approach to facilitate the utilization of feed by tilapia is the addition of probiotic in feed. In this study, we compare the effects of commercial probiotic EM4 and homemade probiotics on tilapia growth. This research was conducted in PT. Sahaja Berkah Abadi at wonosalam, jawatimur, indonesia. The study was designed as a completely randomized design with 3 treatments and 4 replications, encompassing control group (C), commercial probiotics (G1), and homemade probiotic (G2). The commercial probiotics (G1) contained Rhodopseudomonas sp., Lactobacillus sp., Streptomyces sp., and Actinomycetes sp. while the homemade probiotic (G2) contained starter bacteria Lactobacillus casei and herbal plant such as ginger, curcuma, and tumeric. Parameters observed during the study included weight gain (WG), specific growth rate (SGR), and survival rate (SR). The results revealed that both G1 and G2 performed better than the control group. The weight gain for the control, G1, and G2 groups were 2.38±0.03 g, 3.09± 0.01 g, and 3.13 ± 0.03 g, respectively. Similarly, the specific growth rates for the control, G1, and G2 groups were 4.25±0.03%, 5.52± 0.02%, and 5.59 ± 0.03%, respectively, while the survival rate remained at 100% across all groups. The water quality in all treatments during maintenance met the standard requirements for tilapia, with temperatures ranging from 25.5 to 26.7 °C and pH levels between 6.7 and 6.9. These findings suggest that the probiotics incorporated in G2 present a cost-effective alternative to those in G1, offering a promising option for tilapia cultivation.

Reversing the detrimental effects of high stocking density in Oreochromis niloticus juveniles using coenzyme Q10 and l-carnitine dietary supplementation

A 14-week trial was undertaken to examine the effects of coenzyme Q10 (CQ10) and l-carnitine (LC) dietary supplementation, either individually or in combination, on the feed intake, growth, blood biochemistry, immunity, economic viability, and body composition of Nile tilapia fingerlings reared at a high stocking density. The study involved eight groups of 450 tilapia juveniles, with an average weight of 6.083 ± 0.09 g, assigned to different treatments. Two groups were fed a basal diet and stocked at densities of 30 and 60 fish per m3, respectively. The remaining groups were reared at a high stocking density of 60 fish/ m3 and fed diets fortified with LC at 150 mg (G3), LC at 300 mg (G4), CQ10 at 20 mg (G5), CQ10 at 40 mg (G6), LC at 150 mg + CQ10 at 20 mg (G7), or LC at 300 mg + CQ10 at 40 mg (G8) per kg of diet. The findings revealed that high stocking density had an adverse impact on tilapia growth performance. Nevertheless, the inclusion of LC and CQ10 in the diet, whether separately or in combination, significantly improved growth parameters and enhanced survival rates. The G6, G7, and G8 groups showed the most significant improvements in growth and survival. High stocking density resulted in decreased moisture and crude protein content, while LC and CQ10 supplementation increased these components and reduced crude fat and ash content. High stocking density negatively impacted blood metabolites, leading to elevated levels of aspartate aminotransferase, alanine aminotransferase, creatinine, and urea-N, as well as decreased total protein and albumin. However, supplementation with LC and CQ10 effectively alleviated these effects, improving the levels of these parameters. All supplemented groups showed enhanced lysozyme activity and IgM concentration, with the greatest improvements observed in the G6, G7, and G8 groups. Economic analysis indicated that LC and CQ10 supplementation improved final and relative margin, except in the G4 group. In conclusion, the combined supplementation of LC and CQ10 shows promise in enhancing productivity and profitability in tilapia farming under high stocking density conditions, particularly in concrete tanks.

Evaluation of Myostatin and Some Biochemical Variables in Both Type 2 Diabetic and Diabetic Nephropathy Patients

Background: The kidneys are essential organs that keep blood pH stable and eliminate excess water, salts, and aid in the body's waste removal. Aim of the study: The study aims to investigate the importance of myostatin in the development of diabetic nephropathy patients. In addition, the level of urea, creatinine, sodium, potassium, and phosphorus. Materials and methods: A Case-Control study lasted from- November 2023 to January 2024, at Al-Amal Kidney Dialysis Center and Azadi Teaching Hospital in Kirkuk Governorate. The 135 blood samples, their ages (25-70), were divided into three groups. The first group G1 (n:50) patients with T2DM. The second group G2 (n:55) with diabetic nephropathy. The third group G3 for control. Serum samples were utilized to measure MSTN by ELISA, blood urea, serum creatinine, S.PO4, S. Na+, S. K+, and S. Ca++ by spectrophotometer. Results: Significant variations (P&lt;0.05) in MSTN were seen between study groups (8.43±4.69, 10.99±7.05, 5.63±3.38) ng/ml. Additionally, significant differences exist between (G1 vs G2), (G1 vs G3), and (G2 vs G3) with p-value &lt;0.05 Diabetic nephropathy G2 had the highest mean urea and creatinine levels (136.69±38.21, 5.99±1.87), followed by G1 (34.92±9.06, 0.89±0.26) and control group G3 (31.00±4.72), with significant differences (p ≤ 0.001) among three groups. Additionally, G1 with G2, G2 with G3, and G1 with G3 had significant differences (p-value&gt;0.01). Conclusion: This study found higher myostatin, urea, and creatinine in diabetic nephropathy and diabetic patients. The data also showed hyponatremia, hypocalcemia, hyperkalemia, and hyperphosphatemia in diabetic nephropathy and diabetic patients.

A comparative evaluation of fracture resistance of three recent composite systems in Class II mesio occluso distal cavities - An in vitro study

Though composite resins have received popularity as restorative materials because of their physical properties, there was a dearth in the research about fracture resistance among recently emerged composite systems including Tokuyama Estelite Sigma Quick, Admira Fusion, and Beautifil II LS nanohybrid composite systems. To compare and evaluate the fracture resistance of maxillary premolars with class II mesio occluso distal cavities restored with Tokuyama Estelite Sigma Quick, Admira Fusion, and Beautifil II LS nanohybrid composite systems. Current invitro research was conducted on 44 intact human premolar teeth- Eleven specimens were kept completely intact for control group (Group G1). Class II MOD cavities were done with high-speed handpiece and under constant irrigation in remaining 33 teeth, Group G2, Group G3, Group G4 were restored with Tokuyama Estelite Sigma Quick (Tokuyama Dental, Tokyo, Japan.), Beautifil II LS (Shofu, Germany.), Admira Fusion (Shofu, Germany.) respectively. SPSS version 20 software to analyse the data; and ANOVA followed by Tukey’s post-hoc analysis to compare the fracture resistance were used. With a fracture resistance of 1297.27±10.27 N, Group 1 (Control) had highest fracture resistance. Group 4 has the least fracture resistance (Admira Fusion). Every pairwise comparison was significant too. Among the three materials studied, Beautifil II LS had higher fracture resistance and Admira Fusion had the least fracture resistance.

Histopathological Changes in a Rat Model of Diabetic Neuropathy

This study was done to investigate the histopathological Changes in a Rat Model of Diabetic Neuropathy. The 24 male rats used in this investigation were split into two groups of 12 animals. The first group (G1), which consisted of healthy individuals, was given standard saline. Normal saline was administered after G2 (STZ group) received STZ at a dosage of 60 mg/kg. After rats were starved overnight, a single intraperitoneal injection of 60 mg/kg of freshly produced STZ was given to induce diabetes. (0.1 M, pH 4.5) Sodium Citrate Buffer was used to dissolve STZ. On the third day after the injection of STZ, a digital glucometer was used to measure the blood glucose levels of 12-hour fasting rats; hyperglycemia was defined as values greater than 250 mg/dl. In order to assess neuropathic pain, cold allodynia was calculated by counting the number of times the foot withdrew in response to cold stimuli applied to the back of the hand. The sciatic nerve was carefully removed after the sacrifice (after 2 months) and preserved in 10% formalin for histopathological study. Normal blood glucose levels were maintained in the control rats throughout the study. However, G2 exhibited much greater FBG levels than healthy animals. In the 2-month study, the G2 maintained FBG levels above 250 mg/dl. The score for severity of STZ on sciatic nerves showed a significant difference between treated group as compared with G1. No paw reactions were seen when intact animals were subjected to plantar surface acetone. The experimental groups did not show any notable reactions to acetone on the tenth day after the diagnosis of diabetes. On days 20, 30, 40, 50 and 60 after diabetes confirmation, there were significant differences in paw withdrawal frequency between the G1 and G2 (p&lt;0.001). Within the control group, nerve fibres were found to be regularly arranged and there was no evidence of axonal swelling. However, in the G2 group, nerve fibres were found to be significantly disorganised, and there was a notable increase in the number of Schwann cells in the sciatic nerves, suggesting damage, in comparison to the control group.

Reduction of surface treatment time by combination of citric acid and ascorbic acid while restoring shear bond strength of metal brackets bonded to bleached enamel: a pilot study

BackgroundTo investigate the effect of a 50% ascorbic acid with 50% citric acid solution on the immediate shear bond strength (SBS) of metallic brackets after tooth bleaching. The enamel etching pattern and the required quantity of these combined acids as antioxidants following 35% hydrogen peroxide (HP) bleaching were also determined.MethodsThe stability of the solution at room temperature was assessed at various time intervals. Fifty teeth were randomly divided into five groups: non-bleached (G1), bleached then acid etched (G2), bleached followed by a 10-minute treatment with 10% sodium ascorbate and acid etched (G3), 5-minute treatment with 50% ascorbic acid (G4), and 5-minute treatment with a combination of 50% ascorbic acid and 50% citric acid (G5). Groups G2, G3, G4 and G5 were bleached by 35% HP gel for a total of 32 min. Acid etching in groups G1, G2, and G3 was performed using 37% phosphoric acid (Ormco®, Orange, CA, USA) for 15 s. In all groups, metal brackets were immediately bonded using Transbond™ XT primer and Transbond™ PLUS adhesive, with light curing for 40 s. The SBS was tested with a universal testing machine, and statistical analysis was conducted using one-way ANOVA followed by Tukey’s HSD test. The level of significance was set at p < 0.05 for all statistical tests.ResultsStability tests demonstrated that the combined acids remained effective for up to 21 days. Group G5 significantly increased the SBS of bleached teeth to the level of G1 (p < 0.05), while G3 did not achieve the same increase in SBS (p > 0.05). SEM analysis revealed enamel etching patterns similar to those of both control groups (G1 and G2). Kinetic studies at 6 min indicated that the antioxidation in G5 reacted 0.2 mmole lower than in G3 and G4.Conclusion5-minute application of the combined acids enhanced the SBS of bleached teeth comparable to unbleached teeth. The combined acids remain stable over two weeks, presenting a time-efficient, single-step solution for antioxidant application and enamel etching in orthodontic bracket bonding.

Correlation analysis between the changes in plasma ghrelin level and weight loss after sleeve gastrectomy combined with fundoplication

BackgroundLaparoscopic sleeve gastrectomy combined with fundoplication (LSGFD) can significantly control body weight and achieve effective anti-reflux effects. The aim of this study is to investigate the correlation between the alteration in Ghrelin levels and weight loss following SGFD, and to compare Ghrelin levels, weight loss and metabolic improvements between SG and SGFD, with the objective of contributing to the existing body of knowledge on SGFD technique in the management of patients with obesity and gastroesophageal reflux disease (GERD).MethodsA retrospective analysis was conducted on the clinical data of 115 obese patients who underwent bariatric surgery between March 2023 and June 2023 at the Department of Minimally Invasivew Surgery, Hernia and Abdominal Wall Surgery, People’s Hospital of Xinjiang Uygur Autonomous Region. The subjects were divided into two groups based on surgical methods: sleeve gastrectomy group (SG group, 93 cases) and sleeve gastrectomy combined with fundoplication group (SGFD group, 22 cases). Clinical data, such as ghrelin levels before and after the operation, were compared between the two groups, and the correlation between changes in ghrelin levels and weight loss effectiveness after the operation was analyzed. Results: Three months after the operation, there was no significant difference in body mass, BMI, EWL%, fasting blood glucose, triglyceride, cholesterol, and uric acid levels between the SG and SGFD groups (P > 0.05). However, the SGFD group exhibited a significant decrease in body weight, BMI, and uric acid levels compared to preoperative levels (P < 0.05), while the decrease in ghrelin levels was not statistically significant (P > 0.05). Logistic regression analysis indicated that ghrelin levels three months after the operation were influential in postoperative weight loss.ConclusionThe reduction of plasma Ghrelin level in patients after SGFD is not as obvious as that in patients after SG, but it can make obese patients get the same good weight loss and metabolic improvement as patients after SG. Ghrelin level at the third month after operation is the influencing factor of postoperative weight loss.

The digital era of pediatric urological clinical care: telemedicine for management of lower urinary tract symptoms and nocturnal enuresis - a comprehensive tertiary center insight.

Lower urinary tract symptoms (LUTS) and nocturnal enuresis (NE) are complex conditions requiring a long-term follow-up. Telemedicine is an emerging technological tool in the surgical field, and its availability exponentially grew during the COVID-19 pandemic, expanding its application fields, optimizing technical aspects, reducing costs, and ensuring high-quality standards. This work describes our experience with telemedicine in a Division of Pediatric Urology for the follow-up of enuresis and LUTS. A retrospective analysis of our telemedicine preliminary experience was conducted at Regina Margherita Children's Hospital in Turin, Italy. This study included all the patients aged <18 years who were monitored for enuresis and LUTS through telemedicine between September 1, 2021 and July 31, 2023. Clinical data and outcomes were analyzed, and patients and families were asked to voluntary fill an evaluation questionnaire on their satisfaction. Additionally, we focused on the post COVID-19 period, between September 2022 and July 2023, analyzing the data of two different patients' populations: the first one (G1) of patients choosing telemedicine outpatients visits (TOVs) and the second one (G2) of those choosing a face-to-face visit. One hundred five patients were enrolled. One hundred sixty-two TOVs were performed. The median age at first visit was 9.7±0.66 years (range 7-16 years). Diagnosis were: 77/105 (67%) NE and 28/105 (33%) LUTS. The average referred distance between the patients' residence and the hospital was 46.35±129.37 km (range 2-1300 kilometers) and the time taken to overcome it was 44.21±77.29 minutes (range 10-780 minutes). In 64/105 cases (61%) the follow-up was interrupted for total healing or symptoms resumption. Only two cases (2%) required the conversion to an in-person ambulatory consult, due to a social-linguistic barrier. 146/162 families (90%) filled the survey questionnaire at the end of each TOV, reporting in 94% of cases a high satisfaction level. In the comparative statistical analysis of the two patient groups, G1 (52 telemedicine office visits, [TOVs]) vs. G2 (25 face-to-face visits), the average referred distance was 17.78±7.98 km (range: 5-35 km) for G1, contrasting with 7.04±3.35 km (range: 2.5-14 km) for G2 (P=0.00001). Additionally, the waiting time before the visit was 3.96±2.90 minutes (range: 0-10 minutes) for G1, in contrast to 26.52±11.22 minutes (range: 5-44 minutes) for G2 (P=0.00001). Furthermore, a higher compliance with behavioral or pharmacological indications was observed in the G1 group, exhibiting lower adherence in only 12 out of 52 cases compared to 14 out of 25 cases in G2 (P=0.0091). Telemedicine is a proper solution and an effective tool to manage the therapeutic follow-up of NE and LUTS, ensuring suitable quality standards and reducing social costs, such as the loss of working days and transport costs. The implementation and complete integration of its use into the healthcare system should be the goals to pursue in order to take full advantage of all its potentials.
