Glucose-6-phosphate dehydrogenase and its 3D structures from crystallography and electron cryo-microscopy.

Glucose-6-phosphate dehydrogenase (G6PD) is the first enzyme in the pentose phosphate pathway. It has been extensively studied by biochemical and structural techniques. 13 X-ray crystal structures and five electron cryo-microscopy structures in the PDB are focused on in this topical review.

Chemical and biological versatility of pyrazolo[3,4-]pyrimidines: one scaffold, multiple modes of action.

Plain language summary Pyrazolo[3,4-]pyrimidines are chemical compounds possessing remarkable versatility and significance in both biological and chemical contexts. These compounds are composed of specific arrangements of atoms, forming a unique ring structure, which is able to form bonds in a similar way as purines do. In the realm of chemistry, pyrazolo[3,4-]pyrimidines showcase impressive flexibility due to their ability to easily react with various molecules, opening avenues for the creation of novel compounds with diverse properties for potential applications in medicinal chemistry.

Performance of five serological tests in the diagnosis of visceral and cryptic leishmaniasis: a comparative study.

Introduction: Leishmaniasis is a major health problem and its diagnosis still represents a challenge. Since consistent evidence on the comparison of serological methods is lacking, our work aims to compare five serological tests for the diagnosis of visceral and asymptomatic leishmaniasis in southern France, a region where leishmaniasis is endemic.

Methodology: Serum samples from 75 patients living in Nice, France were retrospectively analyzed.

A Calcium- and GTP-Dependent Transglutaminase in .

While human and animal leishmaniasis affect several millions of people worldwide, is the species responsible for visceral leishmaniasis in Europe, Middle East, and America. Antileishmanial drugs present issues associated with drug toxicity and increasing parasite resistance. Therefore, the study of this parasite with a focus on new potential drug targets is extremely useful.

Host genetics impact on SARS-CoV-2 vaccine-induced immunoglobulin levels and dynamics: The role of , , , , , and genes.

Development and worldwide availability of safe and effective vaccines against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) to fight severe symptoms of coronavirus disease 2019 (COVID-19) and block the pandemic have been a great achievement and stimulated researchers on understanding the efficacy and duration of different vaccine types. We investigated the levels of anti-SARS-CoV-2 antibodies (IgG) and neutralizing antibodies (NAbs) in 195 healthy adult subjects belonging to the staff of the University-Hospital of Ferrara (Italy) starting from 15 days up to 190 days (about 6 months) after the second dose of the BNT162b2 (Pfizer-BioNTech) mRNA-based vaccine (n = 128) or ChAdOx1 (AstraZeneca) adenovirus-based vaccine (n = 67) using a combined approach of serological and genomics investigations. A strong correlation between IgG and NAb levels was detected during the 190 days of follow-up ( = 0.
