Background/Aims: Treatment-naive GT 1b-infected patients from mainland China, South Korea and Russia were assessed for SVR at follow-up week 12 (SVR12) after receiving daclatasvir (60 mg, QD) and asunaprevir (100 mg, BID) (DCV+ASV). Methods: Patients were randomized 3:1 to receive DCV+ASV (24 weeks; immediate treatment [IM]) or 12 weeks of placebo followed by DCV+ASV (24 weeks; placebo-deferred treatment [PD]). The primary endpoint was to evaluate SVR12 in the IM arm to the historical rate for peginterferon/ribavirin (70%). Secondary endpoints included overall safety and safety comparisons between the treatment arms during the first 12 weeks. Results: 207 patients were randomized to IM (n=155) or PD (n=52); Asian (86%), female (59%), IL28B CC genotype (68%) and median age 49 (range 18-73) years; cirrhosis (13%), HCV RNA ≥6x106 IU/mL (53%). SVR12 in the IM arm was 92% and broadly unaffected by most baseline factors assessed (Figure); SVR12 was higher in patients without (96%) baseline NS5A-L31M/V or Y93H polymorphisms. There were 6 virologic breakthroughs, 6 relapses and 1 detectable HCV RNA at end-of-treatment in the IM arm. Safety was mostly comparable between the two arms during the first 12 weeks. The most frequent adverse events (AEs; ≥5%) during DCV+ASV (24 weeks) treatment in both arms were aminotransferase, bilirubin and INR elevations, hypertension, fatigue and respiratory tract infections; the most frequent treatment-emergent grade 3/4 laboratory abnormalities were aminotransferase (≤4.5%) and hematologic, lipase and total bilirubin abnormalities (≤2%); one patient (IM) discontinued DCV+ASV for aminotransferase elevations, nausea and jaundice (all reversible); one patient PD) discontinued DCV+ASV for a fatal AE unrelated to treatment. Conclusions: These data demonstrate that DCV+ASV is a highly efficacious and well tolerated treatment for treatment-naive HCV GT 1b-infected patients. Those treated immediately with DCV+ASV achieved a 92% SVR12 rate which was unaffected by factors known to attenuate response to interferon.

This study was conducted to investigate the protective effect of genistein on the antioxidative defence system and membrane fluidity in chick skeletal muscle cells after supplementation with 0, 20, 40, and $80{\mu}mol/L$ genistein in $50{\mu}mol/L$ $FeSO_4/H_2O_2$ treated cells for 24 h. Genistein supplementation recovered the decreased activity of total superoxide dismutase induced by $FeSO_4/H_2O_2$, significantly increased glutathione peroxidase activity (p<0.05) and decreased malondialdehyde production (p<0.05). The treatment of 80 mol/L genistein in $FeSO_4/H_2O_2$ treated cells decreased the secretion of creatine kinase (p<0.05). Fluorescence polarization values and microviscosities observed with $FeSO_4/H_2O_2$ treated cells were significantly higher than those observed with no $FeSO_4/H_2O_2$ treated cells. The addition of $80{\mu}mol/L$ genistein improved the increased fluorescence polarization value (p<0.05) caused by $FeSO_4/H_2O_2$ treatment. The microviscosity value was significantly decreased by adding genistein (p<0.05). In conclusion, genistein protected skeletal muscle cells from oxidative damage by improving antioxidative status and membrane fluidity.

The surface potential and drain current of double-gate metal-ferroelectric-insulator-semiconductor (MFIS) field-effect transistor were investigated by using the ferroelectric negative capacitance. The derived results demonstrated that the up-converted semiconductor surface potential and low subthreshold swing S = 34 (<60 mV/dec) can be realized with appropriate thicknesses of ferroelectric thin film and insulator layer at room temperature. What’s more, a reduction gate voltage about 260 mV can be reached if the ON-state current is fixed to 600 mA/mm. It is expected that the derived results can offer useful guidelines for the application of low power dissipation in ongoing scaling of FETs.

The aim of this study was to evaluate protein expression patterns of liver in response to subacute ruminal acidosis (SARA) induced by high-concentrate diet. Sixteen healthy mid-lactating goats were randomly divided into 2 groups and fed either a high-forage (HF) diet or a high-concentrate (HC) diet. The HC diet was expected to induce SARA. After ensuring the occurrence of SARA, liver samples were collected. Proteome analysis with differential in gel electrophoresis technology revealed that, 15 proteins were significantly modulated in liver in a comparison between HF and HC-fed goats. These proteins were found mainly associated with metabolism and energy transfer after identified by matrix-assisted laser desorption ionization/time of flight. The results indicated that glucose, lipid and protein catabolism could be enhanced when SARA occurred. It prompted that glucose, lipid and amine acid in the liver mainly participated in oxidation and energy supply when SARA occurred, which possibly consumed more precursors involved in milk protein and milk fat synthesis. These results suggest new candidate proteins that may contribute to a better understanding of the mechanisms that mediate liver adaptation to SARA.

The tyrosinase gene was selected as a candidate for uncovering genetic mechanism causing 'black ear' coat color in rabbits. A PCR-SSCP detection method was established for the $881^A{\rightarrow}881^G$ mutation located in the central region of the tyrosinase gene between the CuA and CuB binding region signatures, and this was confirmed by sequencing and alignment. Fully consistent associations between the SNP and 'black ear' coat color were observed by analysis in a "black ear" pedigree and on 61 unrelated individuals. This SNP can serve as a molecular marker for use in "back ear" wool rabbit breeding.

This study was conducted to determine the effect of dietary soy isoflavone (ISF, 0 and 20 mg/kg) on performance, meat quality and antioxidative property in male broilers. Six replicates of 45 birds (42 d old) were used for each treatment. The birds were fed soybean meal-free diets containing 3% oxidized fish oil (acid value, 6.76 mg potassium hydroxide/g; and peroxide value, 6.18 meq/kg) for 3 wk. The results showed that average daily gain, feed intake, feed conversion and carcass traits were not affected by soy ISF. Compared with the control group, breast muscle color redness value and water holding capacity were increased (p<0.05) by ISF supplementation. The activity of plasma catalase was increased by supplementing with 20 mg ISF/kg diet. In breast muscle, Broilers fed 20 mg ISF/kg had decreased production of malondialdehyde and lactic acid. The ISF supplementation elevated total antioxidative capacity and activities of total superoxide dismutase and glutathione peroxidase. The results indicated that dietary ISF could increase redness and water holding capacity of meat, and antioxidative property of meat in male broilers fed oxidized fish oil diet.
