The Diagnostic Utility of Natural Killer Cell Subsets in Deep Vein Thrombosis.

Background: Natural killer (NK) cells are important components of adaptive and innate immune responses. NK cell subsets have different functions and may play a role in vascular disorders. This study aimed to evaluate the proportions of NK cells and their subsets to determine whether they can be used as markers of venous thrombosis and to identify whether there was a link between NK cell proportion and citrullinated histone (H3) levels.

Assessment of the natural killer cell, IFN- and IL-10 blood levels in children with attention-deficit/hyperactivity disorder.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder, affects millions of youngsters and typically persists into adulthood. The pathophysiology of ADHD may be due to an impaired immune response, common genetics, and environmental linkages, as all have been suggested as potential underlying mechanisms for ADHD. During systemic inflammation, natural killer (NK) cells can produce pro-inflammatory cytokines like interferon (IFN- ) and anti-inflammatory cytokines like interleukin (IL-10); this demonstrates the importance of both of their roles as regulators to counteract inflammation and prevent immune-mediated host damage.

Ultrastructural changes and IgA modulatory effect of commercial prebiotic and probiotic in murine giardiasis.

Giardiasis, a parasitic infection of the gastrointestinal tract, is prevalent worldwide. The integrity of the intestinal epithelial barrier plays an important defensive role in giardiasis, and as Oral supplementation with prebiotics and probiotics is known to reinforce the intestinal barrier in many gastrointestinal diseases, this study assessed the effects of prebiotic and probiotic supplementation in giardiasis and compared the results with those obtained after nitazoxanide therapy. Swiss albino male lab-bred mice (n = 50) were divided into three major groups; Group I (control group), i.

Toxoplasmosis and cytomegalovirus infection and their role in Egyptian autistic children.

Autism is a neurodevelopmental disorder with a significantly increased incidence rate across the world over the past few years. Toxoplasmosis and cytomegalovirus (CMV) infection are globally prevalent and have been associated with diverse neurological and psychiatric disorders. A few studies have demonstrated the role of toxoplasmosis and CMV as potential etiological factors for autism.

MicroRNA-146a-5p and microRNA-210-3p Correlate with T Regulatory Cells Frequency and Predict Asthma Severity in Egyptian Pediatric Population.

Background: Severe bronchial asthma (BA) affects 5-10% of children, which imposes socioeconomic burden. Therefore, it is crucial to identify biomarkers for risk stratification in children with BA. T regulatory cells (Tregs) play a balancing role in allergic response regulation.

Apoptotic changes in the intestinal epithelium of -infected mice after silver nanoparticles treatment versus nitazoxanide.

has been identified as one of the prevalent opportunistic parasites that cause diarrhea, which may be persistent and fatal. Current chemotherapeutic agents, including nitazoxanide (NTZ), are frequently associated with therapeutic failure, and their roles in the induction of apoptosis in cryptosporidiosis remain to be a topic of debate. Thus, this study aimed to assess the apoptotic changes in cryptosporidiosis in immunocompetent (IC) and immunosuppressed (IS) mice after treatment with silver nanoparticles (AgNPs) and NTZ either alone or after loading.

Study of transforming growth factor beta 1 gene +869T/C polymorphism in Egyptian rheumatoid arthritis patients and its relation to disease activity.

This study intended to explore the relationship between the +869T/C polymorphism of the transforming growth factor-β1 (TGF-β1) gene and rheumatoid arthritis (RA) predisposition and activity in Egyptian patients. The study involved 30 patients suffering from RA and 30 apparently healthy participants as the control group. The +869T/C polymorphism of the TGF-β1 gene was determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) process.

Study of Monocyte Subsets and Their Surface Expression of CD86 and Serum IL-17 Compared to Serum Procalcitonin as Markers of Early Neonatal Sepsis.

Introduction: Neonatal sepsis can quickly progress to multi-organ failure with high morbidity and mortality, making early diagnosis mandatory. Although being the gold standard, the long duration of blood culture may lead to hazardous neonatal complications. Sepsis activates monocytes and changes their subset distribution with the resultant activation of lymphocytes and adaptive immune cells changing the plasma cytokines levels.

Urinary IgG, serum CX3CL1 and miRNA-152-3p: as predictors of nephropathy in Egyptian type 2 diabetic patients.

The purpose of this study was to assess the role of urinary IgG, serum CX3CL1 and miRNA 152-3p levels as predictors of nephropathy in type 2 Egyptian diabetic patients. Sixty type 2 diabetic patients and twenty healthy controls were enrolled in a cross-sectional study. Then they were grouped into: three groups based upon urine albumin excretion (UAE).

Current status of S. mansoni infection in El-Prince village, Alexandria Governorate.

The present work was implemented to determine the current status of Schistosoma mansoni infection in "El-Prince" village, near Alexandria, which was studied before as a control village between 1985 and 1990. Stool examination was performed on 571 of the inhabitants by Kato thick smear technique and intensity of infection was determined. Prevalence was found to be 15.

Vegetable-transmitted parasites among inhabitants of El-Prince, Alexandria and its relation to housewives' knowledge and practices.

In the present study, stool samples were obtained from 575 individuals from El-Prince, a suburban village of Alexandria, Egypt to detect helminthic eggs and protozoan cysts. The results showed that, 35.7% of the sample had at least one vegetable-transmitted parasite, the highest percentage (46.
