Water hardness is known to control the uptake and toxicity of zinc and other metals through either chemical competition, biological acclimation, or both processes. The dominant process controlling zinc uptake has not been previously elucidated, nor has the effect of calcium been investigated independently of other cations. We determined zinc uptake by rainbow trout acclimated and exposed to fou...

Satellite DNA profiles have been characterized in the congeneric species Palorus ratzeburgii, Palorus subdepressus, Palorus genalis, and Palorus ficicola (Coleoptera, Insecta), each of which contains a single, A + T-rich satellite DNA comprising a considerable portion of the genome (20%-40%). These satellites exhibit insignificant mutual sequence similarity. Using PCR assay, it has been shown t...

Background: Sagittal imbalance is known as the main radiographic driver of disability in adult spinal deformity (ASD).In this study, the association of radiological spinopelvic parameters and clinical outcomes was evaluated following thecorrective surgery of sagittal imbalance, in order to explore the predictive ability of each parameter.Methods: A total of 23 patients, who underwent corrective...

BACKGROUND We used high-frequency stimulation delivered during the refractory period of the atrium and pulmonary veins (PVs) to induce focal firing and atrial fibrillation (AF). This study was designed to demonstrate that bilateral low-level vagosympathetic nerve stimulation (LL-VNS) could suppress high-frequency stimulation-induced focal AF at atrial and PV sites. METHODS AND RESULTS In 23 d...

Low earth orbit (LEO) satellite has the advantages of global coverage, low propagation delay and low path losses, etc. Combined with orthogonal frequency division multiplexing (OFDM) transmission, LEO satellite system can support very high capacity suitable for wideband multimedia traffic. This paper analyzes the channel model and throughput for LEO OFDM satellite communication system. First, s...

OBJECTIVES We sought to validate 4 angiographic measures as potential surrogates for clinical restenosis (target lesion revascularization [TLR]) after stent implantation. BACKGROUND Given the low revascularization rates with drug-eluting stents (DES), an angiographic surrogate of TLR is desirable to reduce the sample size required to demonstrate efficacy in future trials of antirestenosis dev...

We have previously shown that concanavalin A (ConA) induction of suppressor cell activity is impaired in patients with lepromatous leprosy (LL). In this study, we demonstrated that the proportion of cells bearing the Leu8 antigen (associated with suppressor-inducer cells) is low in LL patients and tends to normalize during the erythema nodosum leprosum (ENL) episode. Antigen-induced suppressor ...

Myogenesis and adipogenesis are the important processes determining muscle growth fat accumulation livestock, which ultimately affecting their meat quality. Hanwoo is a popular breed its has been exported to other countries. Providing consumers in beef importing countries with mechanisms related quality necessary promote commercialization of beef. This study aimed compare myogenesis properties ...
