Ssa proteins function in protein translocation into organelles and regulation of the heat shock response (2). Ssb1 and Ssb2 are 99% identical and are associated with translating ribosomes (17); ⌬ssb1 ⌬ssb2 cells are sensitive to cold and to certain translation-inhibiting drugs such as hygromycin B. Reduced numbers of polysomes, previously reported in ⌬ssb1… (More)
Although the mechanism underlying C-type natriuretic peptide (CNP) beneficial effects is not entirely understood, modulating the expression of matrix metalloproteinases (MMPs)/tissue inhibitors of metalloproteinases (TIMPs) may play an important role. The study presented herein was designed as a first demonstration of the regulative effects of CNP on… (More)
Enterovirus 71 (EV71), as a member of the Picornaviridae family, is characterized by a single positive-strand genomic RNA known to cause hand, foot, and mouth disease (HFMD) in children. Since the first identification of EV71 infection in California in 1969, periodic epidemics have broken out worldwide . In China, the first EV71 strain was isolated in… (More)
OBJECTIVE AND METHODS This study established a simple stereological method to obtain quantitative information about two- or three-dimensional structures based on observations from kidney sections in the unilateral ureteral obstruction(UUO) model. RESULTS Tubulointerstitial area(TA) and TA/the area of a rectangular field(RA) were raised gradually, but… (More)
Acupoints, the local initial site of signals of acupuncture or moxibustion stimulation, play an important role in producing clinical therapeutic effects. The whole process of acupuncture stimulation induced improvement of the related visceral dysfunction or regional disorders includes 3 key links: 1) initiation of acupuncture/moxibustion signals from the… (More)
The outstanding experiences of Professor LI Zhi-dao in acupuncture clinic practices are stated in this paper. He believes acupoint and manipulation are the key factors which determine the clinical efficacy. He explains that the accurate acupoint location is the basis of acupuncture manipulation. He clarifies that acupoint location is located by tactile… (More)
Mandibular first molars generally have three or four root canals and rarely have five root canals. This paper described a mandibular first molar with five canals, three mesial and two distal. The detection, treatment and X-ray features were provided to help achieve successful root canal therapy in similar cases.
The study was carried out on the animal model of traumatic shock which induced by ligating bilateral hind legs. The contents of enkephalins in hippocampus, striatum, hypothalamus, diencephalon and brain stem were determined with radioimmunoassay. The results show that: (1) when traumatic shock occurs, the contents of Met-enkephalin are not obvious change in… (More)
