Children with GHD (60) and healthy volunteers (60) participated in this study, and their serum samples are collected from National Diabetes Center- Almustansirya University from the period January to April 2022. Enzyme Linked Immune Sorbent Assay (ELIZA) is used to measure Hep. while Chemiluminescence immunoassay is to measure GH and IGF-1.Results demonstrate significant decrease of p<0.01 in the Hep. level in the sera of GHD patients when compared to healthy individuals, and iron levels increase.

Lytic bacteriophage and its endolysin have the potential to affect and lyse specific bacterial cells making them a possible alternative therapy to antibiotic resistant strains. The study aimed to investigate the synergistic effect of phage/ phage cocktail/ endolysin with vancomycin on E. faecalis isolated from urine samples. The antibioresistant profile 17 E. faecalis was done with an emphasis on the sensitivity to vancomycin. The lytic phages were isolated from the local environment. The infectivity and the coverage rate for the phage and phage cocktail were calculated. The enzyme of the lytic phage was isolated by chromatography. The synergistic effect was tested by turbidity reduction assay to evaluate the growth reduction level. It had been found that 6/17 E. faecalis isolates were resistant to vancomycin, 7/17 isolates were intermediate, and 4/17 were susceptible. Three lytic phages were identified with an infectivity rate of 100%, 76.4%, and 88.2%. The phage cocktail yielded 100% rate of infectivity and 91.6 % coverage rate. The reduction in the growth levels of the 17 E.faecalis after treatment with phage / phage cocktail/ vancomycin/ mixture of vancomycin and phage cocktail was effective. The synergistic effect of vancomcyin together with the phage cocktail significantly reduced the growth of 70.6% of the isolates. The antibacterial activity of vancomycin plus endolysin treatment was revealed in a time dependent manner. Thus, the synergistic effect of vancomycin with phage/ endoloysin illustrated an effective method to treat the antibiotic-resistant strains of E. faecalis to overcome this emerging clinical problem.","PeriodicalId":8687,"journal":{"name":"Baghdad Science Journal","volume":"7 4","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139259745","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 results of the experimental work showed that changing the pH of the suspension has a significant impact on the recovery rate of caffeine. When only water was used as a solvent, the concentration of caffeine increased from 135.061 (mg/L) to 2478.179 (mg/L) by increasing the pH of the suspension to 9. Another promising finding is that by changing the solvent type to an aqueous organic solvent, where the recovery of caffeine augmented remarkably.

The goal of this study was to compare soluble HLA-G (sHLA-G) levels before and after radioactive iodine therapy (RAI) by enzyme immunoassay (ELISA). Immunohistochemistry was used to examine HLA-G protein expression in thyroid tissues from patients with papillary thyroid cancer (PTC) to investigate the relationship between HLA-G expression and patients' clinical variables. Prospective research included 138 blood samples from patients and controls, as well as 25 thyroid paraffin-embedded tissues from individuals suffering from papillary thyroid cancer (PTC) and controls. Our findings demonstrated a significant difference in the means of people who had radioactive iodine therapy against those who did not (Mean SE = 4.19 0.31, 2.216 0.08, respectively).
