Evidencing nickel biosorption capacity of cyanobacteria Chroococcidiopsis sp.: potential metallo-protective agents.

The increasing prevalence of toxic elements such as nickel (Ni) in the environment poses a significant threat to human health due to its carcinogenic effect. The study investigates the Ni biosorption potential of three cyanobacteria strains: Euhalothece sp., Halospira sp.

Intracholecystic papillary neoplasm: A case report.

Introduction And Importance: More needs to be understood concerning the natural progression and visual attributes of intracholecystic papillary neoplasm. Its longevity, especially the rate at which it transitions from benign to malignant growths, remains ambiguous. Consequently, it is imperative to elucidate the intrinsic progression of this precancerous lesion in the gallbladder.

Vaccination strategies for Ebola in the democratic republic of Congo: the who-Ebola modeling collaboration.

Objectives: Assess the effectiveness of ring vaccination in controlling an Ebola virus outbreak in the Democratic Republic of Congo.

Methods: This analysis focuses on two areas of the Democratic Republic of Congo, Beni and Butembo/Katwa, which were affected during the 2018-2020 Ebola outbreak. To simulate Ebola virus transmission, we used a spatially explicit agent-based model with households, health care facilities, and Ebola treatment units.

[Coronarography and etiologies of heart failure with impaired left ventricular ejection fraction in Senegal].

Introduction: Heart failure is a major public health problem because of the number and duration of hospitalizations. Patients with heart failure may have mixed etiologies that are not mutually exclusive, and etiologies vary between high-income and developing countries. The aim of our work was to study the contribution of coronary angiography in the etiological investigation of heart failure with impaired LVEF in the cardiology department of HPD.

2-Cyanopyrimidine-Containing Molecules for N-Terminal Selective Cyclization of Phage-Displayed Peptides.

Current methods for the macrocyclization of phage-displayed peptides often rely on small molecule linkers that nonspecifically react with targeted amino acid residues. To expand tool kits for more regioselective macrocyclization of phage-displayed peptides, this study explores the unique condensation reaction between an N-terminal cysteine and nitrile along with the reactivity of an internal cysteine. Five 2-cyanopyrimidine derivatives were synthesized for this purpose and evaluated for their selective macrocyclization of a protein-fused model peptide.
