They found that Azithromycin was highly effective against both positive and negative bacteria, but its effectiveness decreased when combined with vitamin D. Levofloxacin was the most effective antibiotic, and its efficacy was not affected by the addition of zinc or vitamin D. Acyclovir had a slight effect on bacteria when used alone, but its efficacy improved with zinc. Zinc and Vitamin D had a high degree of effectiveness, but Vitamin D had relatively low efficacy, except against one type of bacteria.\u0000The study aims to evaluate the effectiveness of drugs and vitamins against bacterial infections in COVID-19 patients.

Hereditary hemochromatosis, also known as HFE-related hemochromatosis is carried on by changes in the HFE gene. Investigating the gene mutations of the HFE gene is a way to explore the prevalence of this disease. This study aims to determine the association between hemochromatosis HFE gene mutations (C282Y and H63D) and childhood acute lymphoblastic leukaemia in patients at Basra Specialized Hospital for Children and AL-sadder Teaching Hospital in the Basra governance. QIAamp DNA and Blood Mini Kit were used to isolate and identify Human genomic DNA and detect mutations in the HFE gene using the DNA hybridization method. In this study, the absence of the C282Y mutations in both patients and the control group was identified. However, testing DNA-based hybridization experiments revealed low detection levels of the H63D (homozygous, heterozygous) mutations; in only 12.5% of patients. The H63D (only homozygous) mutations were present in 10% of the control group. The association between patients and the control group is considered statistically significant. The HFE gene mutations (C282Y and H63D), originate in acute lymphoblastic leukaemia in childhood, thus, this study recommends complementary investigations to illustrate this case in more detail with more cases of patients and discover the hidden agents underlying these mutations.","PeriodicalId":23432,"journal":{"name":"University of Thi-Qar Journal of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141275091","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 first pulse is resulted from the passive Q-switching method and the other is resulted from Stokes pulse generated by the laser ray reaction with the Raman medium in the optical system. This study simulated this effect on the characteristics of three pulses (passive Q-switching pulse, Stokes pulse, and anti-Stokes pulse) simultaneously generated from one optical system . The optical system consists of Nd: YVO4, PbWO4, and Cr + 4: YAG as an effective medium, Raman medium, and saturable absorbent material, respectively. The modeling of the rate equations was used, and the Rung-Kutta-Fehelberg numerical method was used to solve the rate equations. The results show increased power of the pulses generated, requiring an increased length of the saturable absorber material used in the system. The results showed that at the shortest length used for the saturated absorbent material, the pulse duration and energy of the three generated pulses were PQS pulse (16.44ns, 1.39mJ), Stokes pulse (12.59ns, 1.148mJ) and anti-Stokes pulse (13.53ns, 1.59mJ), while at the longest length of the saturated absorbent material, the pulse duration and energy were PQS pulse (14.68ns, 1.50mJ), the Stokes pulse (11.41ns, 1.36mJ) and the anti-Stokes pulse (12.38ns, 1.86mJ).","PeriodicalId":23432,"journal":{"name":"University of Thi-Qar Journal of Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141233997","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}

Meanwhile, the rest of the samples showed a complete homology with the corresponding sequences and did not exhibit any detectable nucleic acid variations in comparison with the D. capitatus reference sequences. It was inferred from the tree that the detected nucleic acid substitutions showed a slight effect of the observed variations on the altering evolutionary positioning of the investigated S5 sample in comparison with the other wild-type sequences. This was due to the positioning of the altered samples in the other positions compared with the wild-type counterparts. It was inferred from the tree that our investigated D. capitatus samples were suited in the immediate vicinity to various strains deposited from various multi-national positions.

The highest isolation rate was in urine 25(37.3%), followed by sputum 13(19.4%), and the least isolation was in CSF with one isolate (1.5%). The results revealed that K. pneumonia isolates were multi-drug resistant pathogens (MDR) with high resistance to Ampicillin (97%) and 85% for piperacillin.

K. pneumonia is one of the bacteria that cause urinary tract infections, and it is a widespread multidrug-resistant pathogen, and blaVIM- producing K. pneumoniae are found in clinical samples at Thi-Qar hospitals.
