Environmental hypoxia represents a major physiological challenge for Eriocheir sinensis and Palaemonetes sinensis and is a severe problem in aquaculture. Therefore, understanding the metabolic response mechanisms of E. sinensis and P. sinensis, which are economically important species, to
Synchronized Chinese hamster cells were irradiated in air and in nitrogen at various points in the cell cycle. The irradiations were carried out after flushing with air or nitrogen with the medium removed from the mono-layer of cells. Under these conditions the dose-modifying factor, or oxygen
BACKGROUND
Acute inhalation of mercury fumes or vapors is a rare but frequently fatal cause of acute lung injury. This report describes a rare cause of mercury inhalation from Chinese red.
METHODS
An 87-year-old male inhaled the vapors from heating Chinese red (Cinnabar, mercury sulphide) intended
Chinese hamster ovary cells exposed to hypoxia developed an 80-fold resistance to a subsequent 1-hour exposure to doxorubicin (ADR) in air. Recovery in air before drug exposure resulted in loss of resistance. Cells exposed to hypoxia for 20 hours followed by a 15-hour recovery were still twofold to
A retrospective case controlled study was carried out to study the neonatal characteristics, outcome and narcotic withdrawal syndrome in 51 neonates exposed to narcotic antenatally. The birth weight, head circumference and body length were significantly smaller in the study group while the incidence
An herbal medicine widely used in China, anisodamine, was investigated to determine its effect on the tissue PO2 of an important neural tissue, the retina. The anisodamine was injected intravenously over 10 min into anesthetized cats. Although it reduced mean blood pressure an average of 26%,
Incubation of Chinese hamster ovary cells with etanidazole under hypoxic conditions increases cell killing by subsequent treatment with melphalan under aerobic conditions. We report here that this sensitization can be achieved even if periods of hypoxia are interrupted by reoxygenation.
Obstructive sleep apnea syndrome (OSAS) and hypertension commonly coexist. Clinical studies indicate that OSAS plays a key role in increasing the risk of prevalent hypertension. Chronic intermittent hypoxia (CIH) is the core pathological mechanism of OSAS, and has a close relationship with systemic
Chinese hamster V79 cells were exposed to spirogermanium (SG), and their mitotic activity, population growth, plating efficiency, viability (dye exclusion), and clonogenicity were assayed. Mitotic frequency of cultures in SG decreased initially with increasing drug concentration and later plateaued
Accumulating evidence endorses that excessive K(+) efflux is an ionic mechanism underlying apoptosis both in neuronal and non-neuronal cells. K(+) channels play important roles in mediating the pro-apoptotic K(+) efflux. Chinese hamster ovary (CHO) cells have been widely used for gene transfection
