We report on electrical transport and magnetic properties of quaternary single crystals of Sb 1.98–x V 0.02 Cr x Te 3 and Sb 1.984–y V 0.016 Mn y Te 3 with x ranging from 0 to 0.022 and y ranging from 0 to 0.034 over temperatures from 2 K to 300 K. Ternary crystals Sb 2–z V z Te 3 were reported to have rather small magnetization in the ferromagnetic state due to low spin of vanadium ions. There...
Reactions of diphenyltellurium oxide with organostibonic acid and polymeric triphenylantimony oxide have been investigated independently. Single crystal X-ray diffraction studies have revealed the formation of novel and rare mixed valent Sb(v)/(iii) containing polyoxostibonates {(C6H5)3Te}2{Na2(H2O)2(p-Br-C6H4Sb(V))10(Sb(III))4[(C6H5)2Te]4(O)30(OH)4} and {(C6H5)3Te}4{[(C6H5)2Sb(V)]4(Sb(III))4(O...
BACKGROUND Noninvasive ventilation (NIV) has been recognized as an effective strategy in preventing endotracheal intubation in subjects with acute respiratory failure (ARF). Some interface-related complications have also been recognized, such as skin breakdown (SB). The aim of this study was to determine the frequency of SB and identify potential treatment-related risk factors for its developme...
BACKGROUND The evaluation of solitary pulmonary lesions (SPL) requires a balance between procedure-related morbidity and diagnostic yield, particularly in areas where tuberculosis (TB) is endemic. Data on ultrathin bronchoscopy (UB) for this purpose is limited. To evaluate feasibility and safety of UB compared to SB for diagnosis of SPL in a TB endemic region. METHODS In this prospective rand...
Schisandra chinensis is a traditional Chinese medicine that has multiple biological activities, including antioxidant, anticancer, tonic, and anti-aging effects. Deoxyschisandrin (SA) and schisandrin B (SB), the two major lignans isolated from S. chinensis, exert high antioxidant activities in vitro and in vivo by scavenging free radicals, such as reactive oxygen species (ROS). Ultraviolet B-ra...
The pharmacological and pharmacokinetic profile of SB-222200 [(S)-(-)-N-(alpha-ethylbenzyl)-3-methyl-2-phenylquinoline-4-car boxami de], a human NK-3 receptor (hNK-3R) antagonist, was determined. SB-222200 inhibited (125)I-[MePhe(7)]neurokinin B (NKB) binding to Chinese hamster ovary (CHO) cell membranes stably expressing the hNK-3 receptor (CHO-hNK-3R) with a K(i) = 4.4 nM and antagonized NKB-...
Vanilloid receptor-1 (TRPV1) is a nonselective cation channel, predominantly expressed by sensory neurons, which plays a key role in the detection of noxious painful stimuli such as capsaicin, acid, and heat. TRPV1 antagonists may represent novel therapeutic agents for the treatment of a range of conditions including chronic pain, migraine, and gastrointestinal disorders. Here we describe the i...
Controlled mechanical ventilation (CMV) is known to result in rapid and severe diaphragmatic dysfunction, but the recovery response of the diaphragm to normal function after CMV is unknown. Therefore, we examined the time course of diaphragm function recovery in an animal model of CMV. Healthy rats were submitted to CMV for 24-27 h (n = 16), or to 24-h CMV followed by either 1 h (CMV + 1 h SB, ...
The restriction endonuclease from E. coli B is both an endonuclease and a DNA methylase. Both activities either require or are stimulated by Mg(+2), adenosine triphosphate, and S-adenosyl-L-methionine. The particular activity which the enzyme exhibits depends upon the nature of the SB sites, the genetic sites that identify substrate DNA. Enzymatic treatment of DNA that has an unmodified, wild-t...
