Comprehensive Evaluation of Changes in Placentomes in the Second and Third Trimesters of Pregnancy in Cross-Bred Hamdani Sheep.
Vet Med Sci

Department of Anatomy, Faculty of Veterinary Medicine, Siirt University, Siirt, Turkey.
Background: A proper placentation is required for establishment and continuity of pregnancy. In sheep, placentomes are unique structures that enable nutrition and gas exchange between the mother and the foetus. Although placentomes are dynamic formations, there is limited knowledge of changes in placentomes during pregnancy.

Despite the advances in paleogenomics, red cell blood group systems in ancient human populations remain scarcely known. Pioneer attempts showed that Neandertal and Denisova, two archaic hominid populations inhabiting Eurasia, expressed blood groups currently found in sub-Saharans and a rare "rhesus", part of which is found in Oceanians. Herein we fully pictured the blood group genetic diversity of 22 Homo sapiens and 14 Neandertals from Eurasia living between 120,000 and 20,000 years before present (yBP).

We analyse mathematical models of blood flow in two simple vascular networks in order to identify structural features that lead to the formation of multiple equilibria. Our models are based on existing rules for blood rheology and haematocrit splitting. By performing bifurcation analysis on these simple network flow models, we identify a link between the changing flow direction in key vessels and the existence of multiple equilibria.

Department of Medicine, Ordos Institute of Technology, Ordos, 017000, China.
Objective: To observe how cognitive behavioral intervention affects physical symptoms, B-type Natriuretic Peptide (BNP), Red Cell Distribution Width (RDW), and C-reactive Protein (CRP) in elderly patients with heart failure.
Methods: Convenient sampling method was used to select 98 elderly heart failure patients who visited our hospital from January 2022 to December 2020. Patients were divided into a control group and an observation group using the red and blue ball method, with 49 cases in each group.
Spatiotemporal analysis of Plasmodium falciparum erythrocyte binding antigen-175 gene dimorphism in Ghana.

West African Centre for Cell Biology of Infectious Pathogens, Accra University of Ghana, Volta Rd, Accra, Ghana.
Background: Malaria remains a leading cause of death worldwide, claiming over 600,000 lives each year. Over 90% of these deaths, mostly among children under 5 years, occur in sub-Saharan Africa and are caused by Plasmodium falciparum. The merozoites stage of the parasite, crucial for asexual development invade erythrocytes through ligand-receptor interactions.
