A Correlational Study on Cerebral Microbleeds and Carotid Atherosclerosis in Patients with Ischemic Stroke.

Purpose: This study aimed to investigate the correlation between cerebral microbleeds and carotid atherosclerosis in patients with ischemic stroke.

Subjects And Methods: Patients with ischemic stroke treated in a hospital in China from 2016 to 2017 were enrolled in the study. Based on the results from susceptibility-weighted imaging, the patients were divided into cerebral microbleed and noncerebral microbleed groups.

Postoperative iodine-125 interstitial brachytherapy for the early stages of minor salivary gland carcinomas of the lip and buccal mucosa with positive or close margins.

Background: The purpose of this study was to present our preliminary exploration of safety and efficacy of postoperative low-dose-rate brachytherapy for the early clinical stages of minor salivary gland carcinomas of the lip and buccal mucosa.

Methods: Twenty-seven patients with the early stages of minor salivary gland carcinomas of the lip and buccal mucosa received postoperative I seed interstitial brachytherapy from March 2005 to May 2015. Actuarial likelihood estimates for local control, overall survival, and disease-free survival were calculated by Kaplan-Meier method.

[Effect of bivalent alkaline earth fluorides introduction on thermal stability and spectroscopic properties of Er3+/Tm3+ /Yb3+ co-doped oxyfluorogermanate glasses].

Transparent Er3+/Tm3+ /Yb3+ co-doped oxyfluorogermanate glasses alone containing MgF2, CaF2, SrF2 or BaF2 and nano-glass-ceramics only containing BaF2 were prepared. The thermal stabilities and the up-conversion emission properties of the samples were investigated. Analyses of absorbance spectra reveal that the UV cutoff band moves slightly to shortwave band with the doping bivalent cation mass increasing.

Functional expression of guinea pig growth hormone receptor and its mutants in mammalian cells.

The cDNA of guinea pig (Cavia porcellus) growth hormone receptor (gpGHR) was cloned using RT-PCR in our laboratory. By sequence alignment, substitutions of amino acids conserved in other mammalian GHRs were found. For example, histidine-168 and tyrosine-332 equivalent to positions 170 and 333 in other mammalian GHRs, which were considered to be necessary for the dimerization of GHR and the specific GH-stimulated functions respectively, were replaced by tyrosine and serine in gpGHR.

cDNA Cloning of the Cytoplasmic Domain of Growth Hormone Receptor from guinea Pig and Homology Comparison.

The evolutionary position of guinea pig has not been unequivocally clarified, and it appears to show abnormalities in GH response. The cDNA of GHR cytoplasmic domain from guinea pig was cloned and sequenced. By homology comparison, it was found that the sequence we obtained was different markedly from that of rat or mouse.

cDNA Cloning of the Guinea Pig Growth Hormone Receptor.

cDNA cloning and 1 899 bp sequence of growth hormone receptor (GHR) from guinea pig liver are described. The guinea pig GHR consists of 610 amino acids. The structural feature and homology comparison of guinea pig GHR are also reported.

Effects of Divalent Cations and Disulfide Bond Reducing Agents on Specific Binding of Growth Hormone to Liver Membrane Receptors from Snakehead Fish (Ophiocephalus argus, Cantor).

Divalent cations, Ca(2 ), Mg(2 ) and Mn(2 ) enhance the binding of bream growth hormone (brGH) to snakehead fish liver membrane, and their optimum concentration was found to be 8 12 mmol/L, at which Ca(2 ), Mg(2 ) and Mn(2 ) could increase, respectively, the specific binding to 230%, 180%, and 200%, compared with the binding in the absence of ions. The Eadie-Scatchard plot was used for the dynamic analysis of the Ca(2 ) binding site. A low affinity Ca(2 ) binding site was found in the GH-receptor complex with K(m)=0.
