To investigate the effects of heparin on deep second-degree burn in scalded rats. Thirty Sprague-Dawley rats inflicted with 20% TBSA deep second-degree scalding on the back were employed as the model and were randomly divided into two groups. i,e heparin (H) and normal saline groups (N). Heparin (100 U . kg(-1) . day(-1)) was injected subcutaneously to the rats in H group while normal saline to those in N group once a day. Wound healing rate and immunological indices were determined simultaneously. (1) The wound healing time was much shorter in H group than that in N group (P < 0.005). The granulation tissue growth condition examined by LM and EM was much better in H group that than in N group. (2) The lymphocytic transforming ratio in H group was evidently increased (P < 0.005). And the phagocytic function of the macrophages increased significantly (P < 0.05). But there was no difference between the two groups in terms of hemoltytic plaque test (P > 0.05). Injection of heparin subcutaneously could accelerate burn wound healing and strengthen the systemic cellular immune potential and the macrophage phagocytic capacity of the host, but exerted no effect on the humoral immunity.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.
