Safety and efficacy of L-Glutamine in reducing the frequency of acute complications among patients with sickle cell disease: A randomized controlled study.

To evaluate the safety and efficacy of L-glutamine in reducing vaso-occlusive crisis (VOC) and improving cerebral arterial blood flow in children with sickle cell disease (SCD). This is an interventional randomized controlled trial that recruited sixty SCD patients, aged 9.2 ± 3.

Synthesis of π-conjugated polycyclic compounds by late-stage extrusion of chalcogen fragments.

The "" has proved particularly valuable for the preparation of insoluble and unstable π-conjugated polycyclic compounds (π-CPCs), which cannot be synthesized via in-solution organic chemistry, for their improved processing, as well as for their electronic investigation both at the material and single-molecule scales. This method relies on the synthesis and processing of soluble and stable direct precursors of the target π-CPCs, followed by their final conversion in situ, triggered by thermal activation, photoirradiation or redox control. Beside well-established reactions involving the elimination of carbon-based small molecules, i.

Impact of serum IL 10 on prediction of early allograft rejection in liver transplantation.

Tissue transplantation is the preferred treatment for end organ failure such as heart, lung, kidney, and liver. The immune system recognizes the transplant as non self if the donor and recipient are not genetically identical. Multiple cytokines are involved in this process; however, little is known about their predictive role in rejection.

Neutrophil Respiratory Burst: an immunological indicator of post stroke infection.

Stroke is long known to be followed by a series of immunosuppressive events, and infections might be a cause of death after an acute insult of stroke. The aim of our work was to assess the percentage of neutrophils showing spontaneous oxidative burst in patients with acute ischemic stroke. The study included 30 patients with acute cerebral infarction subjected to the following: magnetic resonance imaging of the brain immediately on admission, and blood sampling on day one of admission (baseline) and after 3 days of admission.

Asymmetry Matters: Diffusion Tensor Tractography of the Uncinate Fasciculus in Children with Verbal Memory Deficits.

Background And Purpose: Verbal declarative memory performance relies on frontotemporal connectivity. The uncinate fasciculus is a major association tract connecting the frontal and temporal lobes. Hemispheric asymmetries contribute to various cognitive and neurobehavioral abilities.

Comparison of hemoglobin level and neutrophil to lymphocyte ratio as prognostic markers in patients with COVID-19.

Background: Anemia can negatively affect the outcome of many diseases, including infections and inflammatory conditions.

Aim: To compare the prognostic value of hemoglobin level and the neutrophil/lymphocyte ratio (NLR) for prediction of coronavirus disease 2019 (COVID-19) severity.

Methods: In this retrospective cohort study, clinical data from patients with laboratory-confirmed COVID-19 were collected from hospital records from 10 April 2020 to 30 July 2020.

The interplay between tumor necrosis factor alpha, disease activity, and depressive symptoms among Egyptian female patients with systemic lupus erythematosus.

One of the most remarkable presentations of systemic lupus erythematosus (SLE) is depression. Our aim was to elucidate the potential relationship between disease activity, depressive symptoms, and tumor necrosis factor alpha (TNF-α) in patients with SLE. Sixty female patients with SLE and thirty comparable healthy controls were recruited.

Neutrophil/lymphocyte ratio and lymphocyte/monocyte ratio in ulcerative colitis as non-invasive biomarkers of disease activity and severity.

Background: Apart from endoscopic interventions, readily attainable cost-effective biomarkers for ulcerative colitis (UC) assessment are required. For this purpose, we evaluated differential leucocytic ratio, mainly neutrophil-lymphocyte ratio (NLR) and lymphocyte-monocyte ratio (LMR) as simple available indicators of disease activity in patients with ulcerative colitis.

Methods: Study conducted on 80 UC patients who were classified into two groups of 40 each according to Mayo score and colonoscopic findings.

Autonomous RFID Sensor Node Using a Single ISM Band for Both Wireless Power Transfer and Data Communication.

This paper addresses the implementation of autonomous radiofrequency identification sensor nodes based on wireless power transfer. For size reduction, a switching method is proposed in order to use the same frequency band for both supplying power to the nodes and wirelessly transmitting the nodes' data. A rectenna harvests the electromagnetic energy delivered by the dedicated radiofrequency source for charging a few-mF supercapacitor.

Study of Possible Relation between Fasting Plasma Glucagon, Gestational Diabetes and Development of Type 2 DM.

Background And Aims: Women who develop GDM (gestational diabetes mellitus) have a relative insulin secretion deficiency, the severity of which may be predictive for later development of diabetes. This study aimed to investigate the role of fasting plasma glucagon in the prediction of later development of diabetes in pregnant women with GDM.

Materials And Methods: The study was conducted on 150 pregnant women with GDM after giving informed oral and written consents and being approved by the research ethical committee according to the declaration of Helsinki.

Expanded peripheral CD4CD28 T cells and its association with atherosclerotic changes in patients with end stage renal disease on hemodialysis.

End-stage renal disease (ESRD) patients, including those on hemodialysis, possess a high risk for cardiovascular diseases, as the first leading cause of death among them. Traditional risk factors do not utterly elucidate this. Throughout the last two decades, CD4CD28 T cells; an unusual subset of T lymphocytes, was detected high with excess cardiovascular (CV) mortality.

Fecal microbiota profile in atopic asthmatic adult patients.

Studies proposed a link between gut microbiota and airway tract. Study the diversity and density of gut microbiota in healthy and asthmatic patients. Semi-quantitative stool cultures were performed from fecal samples collected from 80 adult asthmatic patients and 40 healthy individuals.

Valorization of functional properties of extract and powder of olive leaves in raw and cooked minced beef meat.

Background: Olive leaves (OL), available in huge amounts from pruning, are known to be a useful source of biologically active compounds. This study investigated the potential application of OL as a supplement to minced beef meat in order to develop a functional product. The effect of OL extract or powder (100 and 150 µg phenols g meat) on the quality and stability of raw and cooked meat during refrigerated storage was examined.

Antihypertensive treatment and blood pressure control in patients with hypertension in daily clinical practice: a cross-sectional, multicenter, observational study in Egypt.

Objective: Management of hypertension in Egypt is difficult because of various reasons. This real-life study was conducted to determine BP control rate, treatment modalities, factors influencing the choice of antihypertensive drugs, physicians' satisfaction with the treatment, and demographics of patients with uncontrolled BP who were treated for hypertension in daily clinical practice in Egypt.

Methods: This was a cross-sectional, multicenter, observational study conducted in patients treated for hypertension in out-patient private clinics in Egypt, during October 2011 to June 2012.

Antibacterial action of acetic acid soluble material isolated from Mucor rouxii and its application onto textile.

Acetic acid soluble material (AcSM) is a chitosan-rich fraction isolated from the fungal cell wall materials. The final step in the traditional production of fungal chitosan is the separation of chitosan from the cell wall AcSM via raising the pH to 9-10 followed by centrifugation. This step results in further undesirable economic and environmental effects.
