Immunoglobulins in Tibetans

Observations on the blood pressure of Tibetans.

New aspects of altitude adaptation in Tibetans: a proteomic approach.

A prolonged sojourn above 5500 m induces muscle deterioration and accumulation of lipofuscin in Caucasians, probably because of overproduction of reactive oxygen species (ROS). Because Sherpas, who live at high altitude, have very limited muscle damage, it was hypothesized that Himalayan natives possess intrinsic mechanisms protecting them from oxidative damage. This possibility was investigate...

Fractional Exhaled Nitric Oxide in Healthy Tibetans at High Altitude

BACKGROUND Fractional exhaled NO (FENO) is a marker of airway inflammation. For successful use of this marker it is important to have reference ranges from different healthy populations. The aim of this study was to establish these in healthy Tibetan adults who had always lived at high altitude on the Qinghai-Tibet Plateau. MATERIAL AND METHODS The study included 145 healthy Tibetan subjects,...

Serum immunoglobulins in hypertension.

We measured serum immunoglobulins in 52 persons whose blood pressure was higher than 140/90 mm Hg, and 52 normotensive controls matched for age, sex and race. All were selected from a population of actively employed persons undergoing a routine health evaluation. Contrary to previous reports, the hypertensive subjects did not have higher levels of IgG or IgA than the controls. Sixteen hypertens...

Development of anti-Helicobacter pylori immunoglobulins Y (IgYs) in quail

Helicobacter pylori (H. pylori) is a gram-negative, microaerophilic bacterium that cause the stomach infection in more than 50% of human population worldwide. The aim of this study was to examine the possibility of anti-H. pylori immunoglobulins Y (IgYs) production in quails and evaluate the effect of the different methods of immunization on titers of IgY in egg yolks. Whole cell bacterial anti...
