Synthesis, molecular docking study and biological evaluation of new pyrrole scaffolds as potential antitubercular agents for dual targeting of enoyl ACP reductase and dihydrofolate reductase.

In this study, new series of N'-(2-(substitutedphenoxy)acetyl)-4-(1H-pyrrol-1-yl)benzohydrazides (3a-j) 4-(2,5-dimethyl-1H-pyrrol-1-yl)-N'-(2-(substitutedphenoxy)acetyl)benzohydrazides (5a-j) were synthesized, characterized and assessed as inhibitors of enoyl ACP reductase and DHFR. Most of the compounds exhibited dual inhibition against the enzymes enoyl ACP reductase and DHFR. Several synthesized substances also demonstrated significant antibacterial and antitubercular properties.

Cluster of Differentiation 38 Protein Significantly Adds to the Prognostic Value of Cytogenetic Risk in Patients with Acute Myeloid Leukemia.

Objectives: There is some controversy regarding the clinical significance of cluster of differentiation 38 (CD38) protein in acute myeloid leukemia (AML). We aimed to study the prognostic value of CD38 expression in relation to the standard cytogenetic risk stratification in AML patients.

Methods: In this prospective study, adult patients with AML were diagnosed based on the finding of ≥ 20% blasts in the bone marrow and the flow cytometry.

Perceptions of Parents towards COVID-19 Vaccination in Children, Aseer Region, Southwestern Saudi Arabia.

Vaccines are an important part of the COVID-19 pandemic response plan. This cross-sectional study aims to assess the attitude and perception levels of parents toward COVID-19 vaccines for children aged 0-18 years in the Aseer region of Saudi Arabia. Data were analyzed using SPSS version 16.

Effect of the Hydoxyurea in Yemeni Transfusion-Dependent β-Thalassemia Patients.

The response to hydroxyurea (HU) therapy of 44 Yemeni transfusion-dependent β-thalassemia (β-thal) patients in Sana'a City, Yemen, was assessed. All patients were treated with a dose of 15 mg/kg/day HU for 4-10 months. Thirty-six patients responded partially to HU with clinical improvement of anemia and extramedullary hematopoiesis features, whereas the rest remained almost at the same baseline levels of transfusion dependency.

Proposed low-cost premarital screening program for prevention of sickle cell and thalassemia in Yemen.

In Yemen, the prevalence of sickle cell trait and β-thalassemia trait are high. The aim of this premarital program is to identify sickle cell and thalassemia carrier couples in Yemen before completing marriages proposal, in order to prevent affected birth. This can be achieved by applying a low-cost premarital screening program using simple blood tests compatible with the limited health resources of the country.
