Traditional supervised data classification considers only physical features (e. g., distance or similarity) of the input data. Here, this type of learning is called low level classification. On the other hand, the human ...

ABSTRACT Background Altitude exposure causes acute sleep disruption in non-athletes, but little is known about its effects in elite athletes. The aim of this study was to examine the effects of altitude on two groups ...

Excessive erythrocytosis (EE) [hemoglobin (Hb) >21g/dl] observed in natives at high altitude (HA) seems to be due to elevated serum testosterone levels compared with men without EE at HA. The aim of the study was to determine ...

Background: Currently there are no studies on γ-glutamyltransferase (γGT) levels at high altitude or on the relationship between γGT, uric acid and several dysfunctions. The aim of the study was to determine the association ...

Background: Traditional data classification techniques usually divide the data space into sub-spaces, each representing a class. Such a division is carried out considering only physical attributes of the training data ...

Chronic mountain sickness (CMS), a lack of adaptation to altitude characterized by excessive erythrocytosis (EE), is a health problem associated with life at high altitude. The erythropoietic process is regulated by both ...

Abstract Salinas, Carlo E., Mercedes Villena, Carlos E. Blanco, and Dino A. Giusssani. Adrenocortical suppression in highland chick embryos is restored during incubation at sea level. High Alt. Med. Biol. 12:79–87, ...

Enhanced erythropoietic drive and iron deficiency both influence iron homeostasis through the suppression of the iron regulatory hormone hepcidin. Hypoxia also suppresses hepcidin through a mechanism that is unknown. We ...
