It is also responsible for retardation in growth and poor mental development in growing children, which is the worst attacked age group. Its prevalence varies from geographical regions like tropical and subtropical and also varies from populations like in urban, suburban, and rural. Periodic monitoring of prevalence to set control programs for that locality is needed. Aim To study the prevalence of various parasitic intestinal infections in a rural population in Central India. Materials and methods This descriptive and retrospective study was done in a 350-bed tertiary care hospital located in Central India serving a rural population. We have extensively studied all stool samples collected and reported between August 2019 and May 2022. Results A total of 1120 stool samples were reported during our study period, of which 518 were of females and 602 were of males. Of these 1120 stool samples, 91 samples showed the presence of parasite. The overall prevalence of intestinal parasitic infection in our study population is 8.13%, whereas the prevalence of the same in males and females is 8.63 and 7.53%, respectively. Conclusion We have found no association or effect of sex on intestinal parasitic infections in our study population. The prevalence of the same was lower in our rural population compared with various other studies, indicating good hygiene level in the society. The prevalence was highest in 21–40-year age group. Age group had a significant association with intestinal parasitic infections in our study population.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48920221","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}

This study discussed the effectiveness of iron-depriving strategy on growth, survival, and virulence of S. pyogenes. Materials and methods Some comparisons between different iron-saturated and iron-depleted forms of the main human iron reservoirs (hemoglobin, hemin, transferrin, lactoferrin, and human milk) were tested for their effect on growth and pathogenicity of S. pyogenes. Results and conclusion Although the iron-saturated forms enhanced the growth and survival, the iron-free forms had a bacteriostatic/bactericidal activity against the microbe, and these results were emphasized by the in vivo study. Finally, the bacterial surface proteins as virulence factors were secreted upon iron depletion as indicated by sodium dodecyl sulfate polyacrylamide gel electrophoresis. This study proved that iron-depletion environment increased the resistance and virulence factors of S. pyogenes.

Conventional therapies have adverse effects, which affect human life quality. Tumor microenvironment (TME), also known as surrounding stroma, has a contributory role in cancer development. Understanding the interaction between TME and cancer progression is a challenge and helps to develop new therapeutic strategies that neutralize the tracks taken by cancer cells to grow, spread, and resist therapy. Therefore, targeting TME components may be effective in improving tumor therapy. Using nanotechnology for drug delivery is of great interest, where it overcomes some obstacles such as solubility and absorption of drugs and delivering them to the appropriate place of action. The main target of nanotechnology for drug delivery is the ability to differentiate between normal and cancer cells. It can be concluded that TME is an important complementary strategy for the development of anticancer drugs. Multitargeted therapy has better efficient potential than individual therapy against cancer.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41817167","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}

There is a significant correlation between obesity rates with metabolic syndrome and coronavirus disease-19 in children worldwide. Owing to the high expression in adipose tissue, angiopoietin-like protein 5 (ANGPTL5) might be assumed to have a broad range of physiological processes in lipid, glucose homeostasis, and inflammatory responses. Objective To examine the association between childhood obesity and plasma ANGPTL5 levels in an attempt to demonstrate the probable relationships of plasma levels of ANGPTL5 with unacylated ghrelin and obestatin and its relevance to metabolic parameters in obese versus normal-weight children and adolescents. Patients and methods A total of 90 children between 5 and 15 years of age were randomly enrolled in this cross-sectional case–control study. They were classified into obese patients (n=45) and nonobese controls (n=45). BMI for age was calculated following WHO guidelines. Serum levels of ANGPTL5, obestatin, and unacylated ghrelin were measured and correlated with the anthropometric measurements and biochemical markers of metabolic syndrome. Results A highly significant positive correlation was observed between the serum level of ANGPTL5 and the weight z score. Moreover, a significant positive correlation between ANGPTL5 and the investigated diabetic parameters (glucose, insulin, and homeostasis model assessment for insulin resistance) and high sensitivity C-reactive protein was detected. The increased weight in children was associated with a higher level of ANGPTL5 in parallel with the observed elevated insulin resistance. Conclusion ANGPTL5 might be considered a promising sensitive assessment biomarker to be applied for early diagnosis and prognosis of obese children with a high risk of cardio-metabolic diseases.","PeriodicalId":11568,"journal":{"name":"Egyptian Pharmaceutical Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43272126","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}

The potent strain was identified using 16 s rRNA sequence analysis. Plackett–Burman and central composite sequential designs were used to investigate cultural variables influencing PHB production (central composite sequential design). Results and conclusion Of a total of nine different isolates, three were found to be PHB positive based on the color using Nile Red stain. The potent strain was identified as Bacillus safensis (NR_113945.1). Using one factor at a time experiments, sugar molasses and ammonium sulfate, respectively, were the best carbon and nitrogen sources, whereas the best inoculum was 10 ml/100 ml of fermentation medium. Cultural variables influencing PHB production were studied using Plackett–Burman and central composite sequential designs. Accordingly, the most influential factors on PHB production were sugarcane concentration, inoculum size, and KH2PO4. Under the optimized conditions, a PHB content (93% cell dry weight) of 1.17 folds was attained. Furthermore, the Fourier transform infrared spectroscopy and 1H-NMR results confirmed the produced polymer as PHB.

Objective This work demonstrates the effect of the number of irrigation times per week and foliar spraying of different concentrations of salicylic acid and the interaction between them on the hyssop planted in sandy soil and under the drip irrigation system. Materials and methods In the 2-year experiment, three irrigation treatments, that is, once, twice, and three times per week, were applied with three concentrations of salicylic acid (0, 100, and 200 ppm). The growth parameters, photosynthetic pigments, antioxidant activity, total phenolics, proline content, essential oil percentage, and yield along with the main constituents of the essential oil were studied in hyssop herb to find out the relationship between these characteristics and the applied treatments. Results and conclusion It was observed that increasing the number of irrigation times from once to twice and three times per week increased growth, yield, essential oil percentage (%), content (ml/plant), and yield (l/ha) significantly in both seasons, except essential oil (%) from plants irrigated twice per week in the first season, which increased insignificantly. The essential oil showed the main compounds as 3-pinanone, cis in most treatments, except plants irrigated twice and three times per week and sprayed with tap water, where the main component was trans-3-pinanone (38.70 and 32.94 %, respectively). 3-pinanone, cis relative percent ranged from 40.81 to 63.47% in plants irrigated once per week and from 16.78 to 58.49 % in plants irrigated at twice per week, and then from 30.17 to 47.56 % in plants irrigated three times per week. Oxygenated compounds increased under water deficit (once per week) and decreased with increasing salicylic acid concentration.
