Halomonas faecis sp. nov., a halophilic bacterium isolated from human faeces.

A novel moderately halophilic, Gram-stain-negative, catalase- and oxidase-positive, strictly aerobic, non-sporulating, non-motile rod, designated strain JSM 104105, was isolated from human faeces. Strain JSM 104105 was able to grow with 0.5-18% (w/v) NaCl (optimum 4-9%), at pH 6-10.

sp. nov., a moderate halophile isolated from non-saline farm soil.

A Gram-stain-positive, moderately halophilic, strictly aerobic, endospore-forming, rod-shaped bacterium, strain JSM 102062, was isolated from a non-saline farm soil sample collected from Dehang Canyon in Hunan, PR China. Growth occurred with 0.5-20 % (w/v) NaCl (optimum 4-7 %) at pH 5.

Artificial cold wave-induced cerebral infarction in rats with carotid atherosclerosis.

To investigate the effects of cold on blood pressure, serum endothelin-1 content, serum nitric oxide content, and morbidity of cerebral infarction, as well as assess the therapeutic effect of nimodipine. A total of 200 rats were initially assigned to a normal group (n = 10), sham group (n = 10), and carotid atherosclerosis group (n = 180), and subsequently the animals in the carotid atherosclerosis group were randomly assigned to three groups: non-cold (n = 59), cold treatment (n = 58), and nimodipine (n = 58). Rats in the cold and nimodipine groups experienced an artificial cold wave.

[Macrostructure of sleep in patients with vascular cognitive impairment-no dementia].

Objective: To investigate the sleep structure in patients with vascular cognitive impairment-no dementia (VCI-ND) and its differences from that of normal individuals.

Methods: The whole night sleep record of 20 patients with VCI-ND were monitored by 32-head video-taped polysomnographic system, and the results were compared with the data of 20 normal subjects.

Results: Compared with normal subjects, patients with VCI-ND showed significantly reduced total sleep duration, increased waking times, increased stage 1 sleep, decreased stage 2 sleep, decreased stage 3 sleep, decreased rapid eye movement stage (REM) and reduced sleep efficiency.

Expression of IL 1betaconverting enzyme in 5-FU induced apoptosis in esophageal carcinoma cells.

AIM:To study the role of interleukin 1beta converting enzyme(ICE)in antitumor drug induced apoptosis in tumor cells.METHODS:Morphological changes in human esophageal carcinoma Eca-109 cells after treated with 5-fluorouracil (5-FU) were observed under light and electron microscope. Expression of ICE in the tumor cells exposed to 5-FU was examined by the immunocytochemical method.
