Molecular docking of daunorubicin and etoposide drugs against Leishmania donovani : A theoretical study.

Background Objectives: The human blood parasite Leishmania donovani causes visceral leishmaniasis or grayish discoloration of the skin (black fever/kala-azar). Antitumor drugs such as daunorubicin and etoposide can help to treat such diseases. The computational approach is used to find a better interaction of drugs with the active site of the protein and help to design new drugs.

Immune response, hematological traits, biochemical blood parameters, and histological status of laying hens influenced by dietary chitosan-oligosaccharides.

This experiment aimed to examine the effect of chitosan-oligosaccharides (COS) supplementation in laying hens' diets affected their immune response, hematological characteristics, blood biochemical parameters, and histological status. At the age of 34 wk, 200 laying hens and 20 cocks of the Mandarah chicken strain were allotted into four groups, each consisting of 50 hens and five cocks. The first group acted as a control group, fed on a basal diet.

Lactoferrin: Antimicrobial impacts, genomic guardian, therapeutic uses and clinical significance for humans and animals.

Lactoferrin (LF) is a protein found in several bodily fluids, such as milk. This protein has a diverse range of functions and is evolutionarily conserved. Lactoferrin is a multifunction protein with distinct biological abilities affecting mammals' immune structures.
