Background Compatibility with Panax notoginseng (PN) reduced the plasma concentration of triptolide and delayed the Tmax of Tripterygium wilfordii (TW), the sovereign medicine of Qing-Luo Tong-Bi decoction, which hinted the absorption process of triptolide might be involved in decreasing the toxicity in liver and kidney. Methods The absorption of triptolide, triptonide, wilforlide and tripter...

Previous studies have shown that molecules related to erythrocyte spectrin are present in the cortical cytoplasm of nonerythroid cells. We report here the localization by immunoelectron microscopy of one such molecule, TW-260/240, in the brush border of intestinal epithelial cells. Using highly specific antibodies against TW-260 and TW-240 as well as antibodies against fodrin, another spectrinl...

BACKGROUND Greater diaphragm fatigue has been reported after hypoxic versus normoxic exercise, but whether this is due to increased ventilation and therefore work of breathing or reduced blood oxygenation per se remains unclear. Hence, we assessed the effect of different blood oxygenation level on isolated hyperpnoea-induced inspiratory and expiratory muscle fatigue. METHODS Twelve healthy ma...

Citizen science projects have a long history in ecological studies. The research usefulness of such projects is dependent on applying simple and standardized methods. Here, we conducted a citizen science project that involved more than 3500 Swedish high school students to examine the temperature difference between surface water and the overlying air (Tw-Ta) as a proxy for sensible heat flux (QH...

The aim of the study was to detect changes of both the QT dispersion and T-loop morphology resulting from the changed spatial position of the heart during pregnancy. Electrocardiographic and vectorcardiographic recordings were obtained from 37 healthy women 19-36 years old in the 36th to 40th week of physiological pregnancy and 2 to 6 days after delivery. The same recordings were obtained from ...

O nly tw o polysaccharides, lam inaran and pectic acid, had e lic­ itor activity. Laminaran, w hich was m ore active than pectic acid, was hydrolyzed by tunicase and the hydrolysate was subjected to charcoal and gel filtration colum ns. Introduction o f the pyridylam in...

Purpose: Rates of HIV infection among transgender women (TW) are higher than rates observed among men who have sex with men (MSM), and black or African American individuals are at a disproportionately higher risk for HIV than individuals of other races. Limited information, however, is available regarding the needs of black TW and their risk for HIV. Numerous scholarly works and surveillance re...
