Anemia is defined as a decreased capacity of the blood to carry oxygen and is recognized by packed cell volume, erythrocyte, and hemoglobin values below reference ranges. Causes of anemia in birds include blood loss, heavy metal toxicosis, parasitic infection, and chronic disease. Several differences exist between avian and mammalian physiology, including the avian ability to tolerate greater l...

In 1953, the doctor draft interrupted Dr. Severinghaus' anesthesia and physiology training and sent him to the National Institutes of Health as director of anesthesia research at the newly opened Clinical Center. He developed precise laboratory partial pressure of carbon dioxide (PCO(2)) and pH analysis to investigate lung blood gas exchange during hypothermia. Constants for carbon dioxide solu...

The renin-angiotensin system (RAS) plays a central role in body physiology, controlling blood pressure and blood electrolyte composition. ACE.1 (null) mice are null for all expression of angiotensin-converting enzyme (ACE). These mice have low blood pressure, the inability to concentrate urine, and a maldevelopment of the kidney. In contrast, ACE.2 (tissue null) mice produce one-third normal pl...

The neurovascular unit, composed of neurons, brain endothelial cells, pericytes, microglia, and astrocytes, regulates cerebral blood flow. physical chemical signals govern the physiology unit within network its cellular components. Astrocytes have an essential role in this since they a privileged anatomical relationship with rest cells. They are capable sensing released by their neighboring rel...

NK cells are lymphocytes involved in the innate and adaptative immune response. These located peripheral blood tissues with ample functions, from vigilant to tolerogenic reactions. In endometrium, cell populations vary depending on age, hormones, inflammation. When pregnancy occurs, tissue-resident conventional recruited protect fetus, a On contrary, inflamed various inflammatory down-regulate ...

Pregnancy is a normal but altered physiologic state that results in significant hormonal,mechanical, and circulatory changes. The increases in progesterone and estrogen associated with pregnancy contribute to vascular and central nervous system effects, changes in the balance of bronchoconstrictor and bronchodilator prostanoids, and increases in peptide hormones that alter connective tissue cha...

Despite the promise of hematological parameters and blood chemistry in monitoring the health of marine fishes, baseline data is often lacking for small fishes that comprise central roles in marine food webs. This study establishes blood chemistry and hematological baseline parameters for the pinfish Lagodon rhomboides, a small marine teleost that is among the most dominant members of near-shore...

Food and habitat are important environmental factors, which play significant role in the physiology of fish. The present experiment was conducted to ascertain effects food on hematological parameters rohu Labeo rohita reared from first feeding pond with natural foods aquarium using formulated feed for three months (90 days). Fish were sacrificed after rearing period hemato-biochemical (hemoglob...
