BACKGROUND The autonomic imbalance during acute ischemia is involved in the occurrence of life-threatening arrhythmias. OBJECTIVE To investigate the effect of autonomic nervous system (ANS) modulation by low-level carotid baroreceptor stimulation (LL-CBS) on ventricular ischemia arrhythmias. METHODS Anesthetized dogs were received either sham treatment (SHAM group, n = 10) or LL-CBS treatme...

Cystathionine beta synthase (CBS) is the main contributor to the production of hydrogen sulfide (H2S) in the brain. Exogenously administered H2S has been reported to protect neurons against hypoxic injury, ischemia and LPS-induced neuro-inflammation and in the facilitating of long term potentiation (LTP). Dysregulation of CBS leads to different diseases, which all have mental retardation in com...

As a typical ciliate, Tetrahymena thermophila is a unicellular eukaryote that exhibits nuclear dimorphism: each cell contains a diploid, germ line micronucleus (MICN) and a polyploid, somatic macronucleus (MACN). During conjugation, when a new MACN differentiates from a mitotic descendant of the diploid fertilization nucleus, the five MICN chromosomes are site-specifically fragmented into 250 t...

The spliceosomal small nuclear RNAs (snRNAs) are distributed throughout the nucleoplasm and concentrated in nuclear inclusions termed Cajal bodies (CBs). A role for CBs in the metabolism of snRNPs has been proposed but is not well understood. The SART3/p110 protein interacts transiently with the U6 and U4/U6 snRNPs and promotes the reassembly of U4/U6 snRNPs after splicing in vitro. Here we rep...

Previous in vitro experiments have shown that hyperhomocysteinemia leads to oxidative inactivation of nitric oxide, in part by inhibiting the expression of cellular glutathione peroxidase (GPx-1). To elucidate the role of intracellular redox status on homocysteine-induced endothelial dysfunction and oxidant stress, heterozygous cystathionine beta-synthase-deficient (CBS(-/+)) and wild-type (CBS...

Component based system (CBS) development is now a well accepted design approach in software engineering. Although specific tools used for building CBS perform several checks on the built system, few of them provide formal verification of behavioural properties nor performance evaluation. In this context, we have developed a general method associating to a CBS a formal model, based on Stochastic...

Multidisciplinary cancer boards (CBs) for making cancer treatment decisions have become popular in many countries; however, the status of radiotherapy in CBs and the influence of CBs on radiotherapy decisions have not been studied. To clarify these issues, we reviewed the minutes of our CBs from February 2010 to March 2012, and we classified planned treatments discussed at the CBs into five cat...

OBJECTIVE To use the Visual Object and Space Perception Battery (VOSP) to distinguish Alzheimer disease (AD) from non-AD pathology in corticobasal syndrome (CBS). METHODS This clinicopathologic study assessed 36 patients with CBS on the VOSP. All were autopsied. The primary dependent variable was a binary pathologic outcome: patients with CBS who had primary pathologic diagnosis of AD (CBS-AD...

Coherent backscattering (CBS) of light in random media has been previously investigated by use of coherent light sources. Here we report a novel method of CBS measurement that combines low spatial coherence, broadband illumination, and spectrally resolved detection. We show that low spatial coherence illumination leads to an anomalously broad CBS peak and a dramatic speckle reduction; the latte...
