Article Synopsis
  • The MR1 molecule is a specialized antigen presenter that interacts with T cells, particularly mucosal-associated invariant T (MAIT) cells, by presenting various metabolites.
  • Researchers discovered distinct MR1-restricted T cell receptors (TCRs) in tumor-infiltrating lymphocytes from breast cancer patients, which responded specifically to certain breast cancer cell lines but not others.
  • The study indicates that these TCRs can recognize antigens in breast cancer without being affected by a known MR1 ligand antagonist, suggesting a unique interaction that relies on a specific residue of MR1 (K43).

This case series describes the wide spectrum of clinical presentation, laboratory findings, and morbidity/mortality associated with dengue fever in hematopoietic stem cell transplant recipients, treated in a dengue endemic region. The risk of acquiring viral infections increases manifold after transplant due to the severely immunocompromised state amid conditioning toxicity and immunosuppressive therapy. The classical warning signs of dengue viremia are often masked in posttransplant patients, leading to a missed diagnosis of dengue and grave consequences observed in some of the patients.

() and () are widely found in flora of the Cholistan Desert of Bahawalpur, Pakistan and are traditionally used to treat pain and chronic disease. The current study aimed to evaluate their phytochemical screening, antioxidant activity, phagocytic activity, and analgesic activity. Both the plant extracts were investigated for phytochemical screening, Fourier Transform Infrared (FTIR) analysis, antioxidant by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) method, immunomodulatory activity by macrophages phagocytosis using carbon clearance rate assay and analgesic activity by acetic acid produced writhing method.

Amla () has long been used in traditional folk medicine to prevent and cure a variety of inflammatory diseases. In this study, the antioxidant activity (DPPH scavenging and reducing power), anti-inflammatory activity (RBC Membrane Stabilization and 15-LOX inhibition), and anticoagulation activity (Serin protease inhibition and Prothrombin Time assays) of the methanolic extract of amla were conducted. Amla exhibited a substantial amount of phenolic content (TPC: 663.

In this innovative research, a novel series of thiazolidin-4-one analogues having a 1,3,4-oxadiazole/thiadiazole moiety were derived and the structures of all the newly obtained molecules were established using different physicochemical and analytical means (H-NMR, FTIR, mass spectra, and elemental analyses). The synthesized molecules were then investigated for their antiproliferative, antimicrobial, and antioxidant potential. The cytotoxicity screening studies revealed that analogues D-1, D-6, D-15, and D-16 possessed comparable efficacy, within the IC range (1 to 7 μM), when taking doxorubicin as a reference drug (IC = 0.

By exploiting the ample biological potential of 1,3,4-oxadiazole/thiadiazole ring, 4-substitutedphenyl-1,3,4-oxadiazol/Thiadiazol-2-yl)-4-(4-substitutedphenyl) azetidin-2-one derivatives were prepared. Various substituted azetidin-2-one derivatives have been identified as immunostimulating and antimicrobial, as well as their antioxidant activity. 2-amino 1,3,4 oxadiazole/thiadiazole conjugates were synthesized by mixing semi/thio carbazides and sodium acetate with water and stirring well, followed by adding aldehydes in methanol at room temperature.

Varicose veins are convoluted, expanded, and stretched subcutaneous veins of the lower leg and are the most frequently reported medical condition. This condition has a higher prevalence in Western and developed countries. Inadequacy of the valves results in reflux of blood in the veins of the lower leg.

Tumor-infiltrating lymphocytes (TILs) are a potent source for obtaining tumor-reactive T cell receptors (TCRs). Although comprehensive methods to analyze the TCR repertoire in TILs have been reported, the evaluation system for TCR-reactivity to endogenously expressed antigen in tumor cells remains laborious and time consuming. Consequently, very limited numbers of TCRs in TILs have been analyzed for their reactivity to tumor cells.

The present study was conducted to evaluate the antibacterial activity, ro and cytotoxicity, cell viability and safety of Eastern Medicine coded medicinal formulation Eczegone comprising extracts of (Azin) (Fuin) (Spin) and (Lain). This work also evaluated antibacterial activity of Eczegone formulation having above mentioned plants ethanolic extracts against different bacteria's by disk diffusion method. toxicity of Eczegone formulation was investigated by using human skin keratinocytes HaCaT cell line, crystal violet stained cells, and methyl tetrazolium cytotoxicity (MTT) assay.

The present work was carried out to assess the anxiolytic and antidepressant properties. Swiss albino mice (male) were fed orally with hydroalcoholic extract at different doses 50, 100, and 200 mg 1 hour prior to test with the standard diazepam and fluoxetine. Anxiolytic and antidepressant activities were evaluated by using open field, elevated plus maze, force swimming, and tail suspension test.
