Study of antibiotic resistance and virulence genes in isolated from urinary tract infection patients in Tanta University Hospitals.

This study aimed to investigate the prevalence of antibiotic resistance genes and , as well as the virulence genes , and , in uropathogenic () isolates from the Egyptian population. In this cross-sectional study, a total of 50 isolates were collected from urine samples from patients with urinary tract infections (UTIs) admitted to Tanta University Hospital from December 2020 to November 2021. The isolates were cultured, identified, and tested for antibiotic susceptibility by the disc diffusion method.

Role of Both Protein C and Antithrombin III as Predictors of Stage of Liver Disease in Chronic Viral Hepatitis B or C Infected Patients.

Background & Aims: Chronic liver disease is characterized by complex hemostatic disorders because the liver is the site where most of the coagulation factors and their inhibitors are synthesized. The aim of this study was the evaluation of protein C and antithrombin III in different stages of chronic hepatitis B and C and to determine their possible role as markers of liver cell damage in different clinical stages.

Methods: The study included 60 subjects who were subdivided into 4 groups: (Group I): 15 patients diagnosed as chronic viral hepatitis B or C, (Group II): 15 patients with compensated liver cirrhosis, (Group III): 15 patients with decompensated liver cirrhosis, and (Group IV) (control group): 15 healthy individuals.

Gonadal Hormones in Adolescent Females with β-Thalassemia in Relation to Iron Load.

Background: Beta-thalassemia is 'a hereditary blood disorder characterized by reduced or absent beta globin chain synthesis, resulting in reduced hemoglobin in red blood cells, decreased RBCs production and anemia'. Patients with thalassemia major require repeated blood transfusions which 'lead to accumulation of iron in different tissues, including tissues of endocrine glands'. This study aims to evaluate serum gonadal hormones levels in adolescent females with β-thalassemia in relation to iron overload.

Study of gonadal hormones in Egyptian female children with sickle cell anemia in correlation with iron overload: Single center study.

Objective/background: Sickle cell disease is a hereditary hemoglobinopathy characterized by abnormal hemoglobin production, hemolytic anemia, and intermittent occlusion of small blood vessels, leading to tissue ischemia, chronic organ damage, and organ dysfunction including endocrine organs. The aim of this work was to evaluate some gonadal hormones in female children with sickle cell anemia (SCA) in correlation with iron overload.

Methods: This study was conducted on 40 female children with SCA with a serum ferritin of > 1000ng/mL, who were attendants at the Hematology Unit, Pediatric Department, Tanta University, Tanta, Egypt in the period from May 2012 to April 2014.

Significance of immunoregulatory T cells in different stages of breast cancer patients.

Evidence from breast cancer patients suggests that increased T suppressor cells activity may be associated with poor immune responses to tumor antigens and contribute to immune dysfunction. It was demonstrated that these suppressor cells could be CD4+CD25+ T regulatory cells (Treg cells). FOXP3, a forkhead/winged helix transcription factor was found to be essential for the development and control of Tregs.

Flowcytometric study of expression of perforin and CD134 in patients with systemic lupus erythematosus.

Perforin is a membrane-disrupting protein that allows the entry of granzymes into a target cell inducing degradation of target substances in the cytoplasm and nucleus thus leading to programmed cell death or apoptosis. CD134 was originally described as an activation antigen found on activated T cells. In this work Flowcytometry was used to evaluate the expression of perforin and CD134, as a costimulatory molecule on T cells, in patients with Systemic Lupus Erythematosus (SLE) to elucidate their role in the pathogenesis of SLE and disease severity.
