Objectives: In this research, our goal was to assess the anti-parasitic effect of silver nanoparticles (Ag-NPs) based on ginger extract on T. gondii tachyzoites. Methods: This study was conducted to assess the effects of various concentrations of nanoparticles on the parasite using light microscopy. The MTT assay was also conducted to evaluate the toxic effects of silver nanoparticles based on ginger extract on macrophage cells. In addition, the potential apoptosis of T. gondii by silver NPs was assessed using the flow cytometry technique. Results: Based on the tachyzoite assay using microscopic examination, it was observed that the higher the NPs concentration and the longer the parasite’s exposure to NPs, the greater the lethal effect of NPs on tachyzoites. The IC50 (inhibitory concentration) for NPs against T. gondii tachyzoites was 2 ppm. Also, according to the MTT assay, the 40 ppm concentration of nanoparticles had the most toxic impact on macrophages. Moreover, silver NPs led to apoptosis in approximately 55.22% of tachyzoites based on the flow cytometry technique. Conclusions: Based on the above results, it is concluded that silver nanoparticles based on ginger extract have a lethal effect on T. gondii and induce apoptosis in this parasite. This study encourages further studies in vivo.","PeriodicalId":15058,"journal":{"name":"Journal of Archives in Military Medicine","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83328549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: Therefore, the current study aimed to determine the effect of two eccentric resistance training methods with and without blood flow restriction on serum IL6 and MMP9 levels in active young men. Methods: In this quasi-experimental study, 16 healthy men with a mean age of 27.8 ± 2.85 (years), the weight of 79.4 ± 12.4 (kg), and a body mass index of 25.5 ± 3.7 (kg/m2) were randomly assigned to either low-intensity eccentric group with BFR or the high-intensity eccentric without BFR. The high-intensity (70% - 80% maximum voluntary contraction MVC) eccentric exercise without BFR included 3 - 5 cycles of eccentric contraction of the quadriceps muscles, up to exhaustion, whereas low-intensity eccentric exercise executed similar exercise modality at intensity of 20% - 30% MVC with blood flow restriction up to exhaustion. Blood samples were taken from antecubital both before and after the exercise to measure serum IL6 and MMP9 values using the ELISA method. Data were analyzed using paired t-test and analysis of variance with repeated measure test in SPSS version 22. A P value of < 0.05 was defined as statistically significant. Results: High-intensity resistance per se and low-intensity resistance exercise with BFR similarly resulted in a non-significant reduction of IL-6 and elevated levels of MMP-9 serum levels in active young men. Conclusions: Overall, the results indicated that a low-intensity resistance exercise session with restricted blood flow and a high-intensity resistance exercise without blood flow restriction equally did not affect IL6 and MMP9 serum of active young men. Further studies are needed to clarify the exact exercise modality that sufficiently stimulates angiogenesis.","PeriodicalId":15058,"journal":{"name":"Journal of Archives in Military Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90606593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Twelve female subjects (age 22.5 ± 2.24, hight159 ± 0.06, weight 55.22 ± 12.73) participated in this cross-design study and were tested randomly after either 30- minute of pre-cooling using ice jackets or under control conditions (no pre-cooling) in two separate sessions with three days interval between each session. This was immediately followed by the RAST anaerobic power test. Buerer FT-70digital thermometer, polar-FT60 heart rate monitoring, micro lifeblood pressure monitoring, hp-cosmos lactometer, and ELISA technique were used to measure core body temperature, heart rate, blood pressure, blood lactate, and Lactate dehydrogenase, respectively. T-independent and dependent tests were also applied to compare changes both between and within groups. Results: Data on core temperature, heart rate, maximum power output, and fatigue index after pre-cooling were significantly higher in the pre-cooling group than the control group (P < 0.05), but no significant difference was observed between the groups concerning the blood lactate levels, mean and minimum power output, and blood pressure (P < 0.05).

Surgical site infections can result in pain, discomfort, prolonged hospital stay, increased exposure to antimicrobials, and consequentially, increased healthcare costs. Objectives: The study intended to characterize the incidence, etiology, and emerging resistance of SSI in a 1000-bed tertiary-care teaching hospital in New Delhi. Methods: The ambispective study was conducted in a 1000-bed tertiary-care teaching hospital in New Delhi. Clinical, laboratory, and environmental surveillance and screening of health care providers (HCPs) were conducted using the National Healthcare Safety Network (NHSN) definitions and methods given by the US Centers for Disease Control and Prevention (CDC). Results: With 3,541 patients admitted to the Gynecology and Obstetrics Ward and General Surgical Ward of the hospital, the total episodes of SSI were 80 (2.26%). The mean rates of superficial, deep, and organ space SSI were 46.25%, 47.5%, and 6.25%, respectively. The most common organisms isolated were Acinetobacter baumannii (23.75%), Pseudomonas aeruginosa (17.5%), Escherichia coli (15%), and Staphylococcus aureus (12.5%). Conclusions: The rate of SSI in our study was comparable to the unadjusted rates in India, lower-middle, upper-middle, and high-income countries worldwide. Patients with pre-existing medical illness, prolonged operation time, and wound contamination are strongly predisposed to surgical site infection.","PeriodicalId":15058,"journal":{"name":"Journal of Archives in Military Medicine","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81468185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: Therefore, the purpose of this study was to determine the effects of type and intensity of muscle contraction with different recovery periods on anaerobic power and peak torque in young trained girls. Methods: Twelve female subjects (age: 22 ± 2.95 years; height: 165.42 ± 5.35 cm; weight: 57.33 ± 9.15 kg) who had at least two years of continuous training experience were randomly selected. The subjects performed the contraction protocols (isometric (3×70/7s), concentric (3 × 90/4), and eccentric (3 × 110/5)) or control conditions in eight sessions with at least 48 hours intervals between the sessions. In this study, the countermovement jump test and Biodex isokinetic device (60°.S-1) model (ISO-1) were used for measuring anaerobic power and maximum peak torque, respectively. Two-way repeated-measures ANOVA and one-way independent ANOVA were used for analyzing the data (P < 0.05). Results: The between-group comparisons showed that the highest anaerobic power and peak torque values in immediate and three-minute recovery periods were seen in the concentric protocol, and the highest values in seven-minute recovery periods were seen in the eccentric protocol (P < 0.05). These variables were also significant in concentric and eccentric contractions in within-group comparisons (P < 0.05). Conclusions: Eccentric contraction, similar to other contractions, can produce PAP. It seems that eccentric contractions due to a higher intensity of contractions can maintain more consistency of PAP than do other contractions.","PeriodicalId":15058,"journal":{"name":"Journal of Archives in Military Medicine","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91190621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is one of the extraesophageal manifestations of gastroesophageal reflux disease (GERD), involving the laryngeal regio. The laryngopharyngeal epithelium is more susceptible to reflux-related tissue injury than the esophageal epithelium. Objectives: This study aimed to test the hypothesis of whether severe vitamin D deficiency results in increased Laryngopharyngeal reflux (LPR) symptoms in Indian females. The objective was to find out the prevalence of LPR in the severe vitamin D deficient Indian female population. Methods: A descriptive observational study was done at a multispecialty polyclinic in New Delhi, India, over a period of one year. Based on a pilot study, a sample size of 185 individuals was taken. All females referring to the general outpatient department (OPD) with vitamin D levels below 20 ng/ml were included. The frequency of LPR symptoms in the study participants was assessed using the reflux symptom index (RSI) and reflux finding score (RFS) given for all symptomatic patients using a validated scoring system. The data were analyzed descriptively with Microsoft Excel and SPSS version 21 using appropriate tests. Results: In this study, 92% of the subjects aged more than 25 years, and the mean vitamin D level was 9.87 (± 3.425) ng/ml. Moreover, 74% of study participants had severe vitamin D deficiency (≤ 10 ng/ml). The mean RSI for our study participants was 14.54 (± 10.353). Also, the mean RFS was 1.77 (± 3.069). No significant correlation was established between the severity of vitamin D deficiency and RSI as well as RFS. The prevalence of LPR was 43%. Conclusions: Hypovitaminosis D does not have any effect on LPR in the Indian female population.","PeriodicalId":15058,"journal":{"name":"Journal of Archives in Military Medicine","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89812728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although bismuth shields can reduce the dose in the right proportions, their use is controversial due to the reduced image quality. Objectives: The aim of this study was to investigate the performance of a new combination of X-ray absorber structures that have less effect on image quality parameters. Methods: First, various shields with different weight percentages of Cu and Bi were made, then the percentage of dose reduction and image quality were evaluated via phantoms. Finally, Shield with the least effect on image quality was evaluated for clinical evaluation on 20 patients. Results: Shielding with thicknesses of 1T and 3T reduced the Entrance skin dose of ovarian by about 52% and 73%, respectively. Shields with 90% cu-10% Bi and 100% Bi structures had the least and most destructive effects on image quality, respectively, and also have the same image quality. The 10% Bi-90% Cu shield provided a 21% greater dose reduction than the bismuth shield. Also, this 1T thick shield did not create an artifact in the reconstructed images. Conclusions: Shields are flexible, inexpensive, and user-friendly for ovarian shielding in abdominal and pelvic CT scans. Unlike bismuth shields, shields do not have the detrimental effects of image quality degradation.","PeriodicalId":15058,"journal":{"name":"Journal of Archives in Military Medicine","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74719615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
