On-line measurement of respiration plays an important role in monitoring human physical activities. Such measurement commonly employs sensing belts secured around the rib cage and abdomen of the test object. Affected by the movement of body tissues, respiratory signals typically have a low signal-to-noise ratio. Removing tissue artifacts therefore is ...

Diagnosis of dysglycemic states is likely delayed as current diagnostic criteria apply absolute threshold values to a process that is continuous. The importance of this relates to forestalling opportunities for earlier diagnosis when prevention and reversibility are more likely to occur by preventing further β cell dysfunction. Although the optimal ...

Oxidative stress and apoptosis play key role in the pathogenesis of acute kidney injury (AKI). We hypothesize that Astragaloside IV(AS-IV) prevents AKI through inhibiting oxidative stress and apoptosis. The rats were divided into sham control, saline-,vehicle-, or AS-IV-treated groups. AS-IV (20 mg/kg) was orally administered once daily to the rats for ...

The infrared spectrum of the disilane cation, Si(2)H(6)(+), in its (2)A(1g) ground state is inferred from photodissociation of cold Si(2)H(6)(+)-Ar(n) complexes (n = 1, 2). Vibrational analysis is consistent with a D(3d) symmetric structure of H(3)SiSiH(3)(+) generated by ionization from the bonding σ(SiSi) orbital. Structural, vibrational, and electronic properties of ...

We have shown that two multidomain adaptor proteins, p140Cap and vinexin, interact with each other and are likely to be involved in neurotransmitter release. Because the basic molecular mechanism governing neurotransmitter and insulin secretion is conserved, these two proteins may also to play pivotal roles in insulin secretion. We therefore ...

Both vitamin D (VD) signaling and Nur77 are implicated in dopaminergic neurotransmission and dopamine-related neuropsychiatric disorders, such as schizophrenia and Parkinson's disease. Developmental vitamin D (DVD) deficiency rats exhibit schizophrenia-like behaviors and disturbance of dopamine system, which could be partly normalized by haloperidol treatment. By blocking dopamine D(2) receptor, haloperidol ...
