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.

Factors influencing the likelihood of dental service checkup: results from a survey in Saudi Arabia.

Background: The funding and delivery of healthcare including dental care in the Kingdom of Saudi Arabia (KSA, or Saudi Arabia) is undergoing a process of reform. To inform this process, it is important that policymakers are aware of the relationships between service use, specific types of use, and the factors that influence this. Currently, there is a paucity of research in this area in KSA that examines dental service use for checkups at a national level and none that examines differences in this use across regions or that examines explicitly the role of income.

Influence of dietary mannan-oligosaccharides supplementation on hematological characteristics, blood biochemical parameters, immune response and histological state of laying hens.

This study aimed to determine the influence of dietary mannan-oligosaccharides (MOS) on the immune system, hematological traits, blood biochemical parameters, and histological state of laying hens. At 34 wk of age, The Mandarah chicken strain's 120 laying hens and 12 cocks were divided into 4 groups, each with 30 hens and 3 cocks. The first group performed as a control group, which nourished on a basal diet.

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.

Impacts of Changing the Curriculum Design on the Examination Results of Anatomy and Physiology Course.

Introduction Innovating strategies have become a compulsion in all fields associated with improved outcomes. Similarly, an innovation was introduced in the curriculum design and content to be tested for the Anatomy and Physiology course at the College of Science and Health Professions (COSHP), King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS), in the spring semester of 2020. Before the COVID-19 pandemic, until the spring semester of 2019, two examinations were conducted as continuous assessments (Midterm I and II), followed by a comprehensive Final examination.
