In the title hydrate, C(10)H(10)O(4)·H(2)O, the six-membered aliphatic ring that is fused to the benzene ring has a sofa shape, with the hy-droxy group in the 3-position (that represents the sofa back) of the aliphatic ring occupying a quasi-axial position. The hy-droxy group of the aromatic ring is hydrogen-bond donor to the carbonyl O atom; other O-H⋯O hydrogen bonds link the organic mol-ecul...

The Movement Disorder Society Task Force for Rating Scales for Parkinson's disease (PD) prepared a critique of the Hoehn and Yahr scale (HY). Strengths of the HY scale include its wide utilization and acceptance. Progressively higher stages correlate with neuroimaging studies of dopaminergic loss, and high correlations exist between the HY scale and some standardized scales of motor impairment,...

An electroanalytical method has been introduced for highly sensitive determination of hydralazine hydrochloride (Hy-HCl) based on its oxidation at a glassy carbon electrode modified with multiwalled carbon nanotubes (MWCNT/GCE). Studies showed that the electrochemical oxidation of Hy-HCl was accompanied by adsorption and highly sensitive responses could be achieved by adsorptive stripping volta...

The escalating cost of Pt metal has prompted researchers to incorporate other metals into Pt/catalysts reduce the amount Pt. In this work, several bimetallic Pt-Zr/HY-zeolite catalysts were prepared by incorporating small amounts inexpensive Zr Pt/HY-zeolite form an active and selective catalyst. Results showed that although half required platinum was used, catalytic activity Pt-Zr/HY catalyst ...

CONTEXT Hypoxia and muscle contraction stimulate glucose transport in vitro. We have previously demonstrated that exercise and hypoxia have an additive effect on insulin sensitivity in type 2 diabetics. OBJECTIVES Our objective was to examine the effects of three different hypoxic/exercise (Hy Ex) trials on glucose metabolism and insulin resistance in the 48 h after acute hypoxia in type 2 di...

In recent years, much evidence has accumulated which demonstrates that an animal's immune system has the capacity to recognize its own antibody idiotypes. These findings suggest that self-idiotypic recognition may potentially play a role in the regulation of B-cell responses. The experiments presented in this report were carried out to determine if an animal develops the ability to specifically...

Lipid catabolism disorder is the primary cause of atherosclerosis. Transcription factor EB (TFEB) prevents atherosclerosis by activating macrophage autophagy to promote lipid degradation. Hypericin-mediated sonodynamic therapy (HY-SDT) has been proved non-invasively inducing THP-1-derived macrophage apoptosis; however, it is unknown whether macrophage autophagy could be triggered by HY-SDT to i...

In the title mol-ecule, C(11)H(12)N(2)O(4), the dihedral angle between the benzene ring and imidazolidine ring is 7.1 (5)°. In the crystal structure, the hy-droxy groups are involved in the formation of inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules related by translation into C(2) chains along the b axis.
