The role of Interleukin-21 (IL-21) in allergic disorders: Biological insights and regulatory mechanisms.

In recent decades, allergic diseases subsequent from an IgE-mediated response to specific allergens have become a progressively public chronic disease worldwide. They have shaped an important medical and socio-economic burden. A significant proportion of allergic disorders are branded via a form 2 immune response relating Th2 cells, type 2 natural lymphoid cells, mast cells and eosinophils.

Detection of Methylene Tetrahydrofolate Reductase (MTHFR C677T) Mutation among Acute Lymphoblastic Leukemia in Sudanese Patients.

Background: A genetic polymorphism that causes abnormal folate metabolism may lead to genomic instability and increase susceptibility to malignancies such as Acute Lymphoblastic leukemia (ALL). The purpose of this research is to identify methylene tetrahydrofolate reductase (MTHFR C677T) (NCBI ID: 4524) mutation in ALL patients.

Methods: The study was a descriptive case-control hospital-based study with one hundred Sudanese participants divided equally into fifty (50) Sudanese ALL diagnosed patients as cases and fifty (50) Sudanese individuals as controls.

Comparative analysis of immunological biomarkers in COVID-19 and bacterial pneumonia.

Coronavirus disease 2019 (COVID-19) is a severe and infectious respiratory condition caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This case-control study aimed to evaluate serum levels of various immunological markers in patients with COVID-19 compared to those with bacterial pneumonia and a healthy control group. Serum samples were collected from adult participants across various COVID-19 isolation centers, including Kassala State and Ahmed Gasim Hospital, between April and June 2021.

High expression of angiotensin-converting enzyme 2 receptor (ACE-2), transmembrane protease serine (TMPRSS), and P-selectin in platelets lead to thrombosis formation in COVID-19 patients.

Objective: The purpose of the present study is to see if the presence of angiotensin-converting enzyme 2 (ACE-2), transmembrane serine protease 2 (TMPRSS), and P-selectin in platelets increases the risk of thrombosis in COVID-19 patients.

Patients And Methods: This was a cross-sectional study conducted in the COVID-19 isolation center between January and September 2021 and comprised 61 COVID-19-infected patients, 21 of whom were in the intensive care unit (ICU) and 40 of whom were non-ICU patients (non-ICUP) in the isolation center. The coagulation profile, as well as the ACE-2, TMPRES, and P-selectin receptors, were all assessed in addition to the complete blood count (CBC).
