Objective: The aim of the present study was to identify the impact of early weaning of lambs at approximately seven weeks of age onto a herb-clover mix on the liveweight gain of lambs and their dams. Methods: In 2015, twin-born lambs that weighed a minimum of 16 kg (n = 134) were randomly allocated to one of three treatments: i) Early-weaned (58 days after the midpoint of lambing) onto an unrestricted allowance (>1,200 kg dry matter/ha) of herb-clover mix (HerbEW); ii) Lambs+dams unweaned onto an unrestricted allowance of herb-clover mix until conventional weaning (95 days after the midpoint of lambing) (HerbCW); iii) Lambs+ dams unweaned onto an unrestricted allowance of grass-clover pasture until conventional weaning (GrassCW). In 2016, twin-born lambs that weighed a minimum of 16 kg (n = 170) were randomly allocated to one of four treatments: i), ii), iii) (similar to 2015) and iv) Lambs+ dams unweaned onto a restricted allowance (<1,200 kg dry matter/ha) of grass-clover pasture until conventional weaning (93 days after the midpoint of lambing) (Restricted-GrassCW). Results: In 2015, liveweight gain from L58 to L95 of HerbCW and GrassCW lambs did not differ (p>0.05), but were greater than HerbEW lambs. In 2016, HerbCW lambs had greater (p<0.05) liveweight gains from L51 to L93 than GrassCW followed by HerbEW and Restricted-GrassCW lambs. In 2015, liveweight gain from L58 to L95 of HerbEW ewes were greater than both GrassCW and HerbCW ewes while in 2016, liveweight gain of from L51 to L93 GrassCW and HerbCW ewes did not differ (p>0.05) but were greater (p<0.05) than those of HerbEW and Restricted-GrassCW ewes. Conclusion: These results indicate that when grass-clover pasture supply can be maintained at unrestricted intake level, there may be no benefit of weaning lambs early. However, at restricted pasture conditions lambs can achieve greater liveweight gains when weaned early onto a herb-clover mix.

To develop a potent hypoxia-inducible promoter, we evaluated the usefulness of chimeric combinations of the (Egr-1)-binding site (EBS) from the Egr-1 gene, the metal-response element (MRE) from the metallothionein gene, and the hypoxia-response element (HRE) from the phosphoglycerate kinase 1 gene. In transient transfection assays, combining three copies of HRE (3 × HRE) with either EBS or MRE significantly increased hypoxia responsiveness. When a three-enhancer combination was tested, the EBS–MRE-3 × HRE (E–M–H) gave a hypoxia induction ratio of 69. The expression induced from E–M–H-pGL3 was 2.4-fold higher than that induced from H-pGL3 and even surpassed the expression from a human cytomegalovirus promoter-driven vector. The high inducibility of E–M–H was confirmed by validation studies in different cells and by expressing other cDNAs. Gel shift assays together with functional overexpression studies suggested that increased levels of hypoxia-inducible factor 1α, metal transcription factor-1 and Egr-1 may be associated with the high inducibility of the E–M–H chimeric promoter. E–M–H was also induced by hypoxia mimetics such as Co<SUP>2+</SUP> and deferoxamine (DFX) and by hydrogen peroxide. Gene expression from the E–M–H was reversible as shown by the reduced expression of the transgene upon removal of inducers such as hypoxia and DFX. In vivo evaluation of the E–M–H in ischemic muscle revealed that erythropoietin secretion and luciferase and LacZ expression were significantly higher in the E–M–H group than in a control or H group. With its high induction capacity and versatile means of modulation, this novel chimeric promoter should find wide application in the treatment of ischemic diseases and cancer.Gene Therapy (2006) 13, 857–868. doi:10.1038/sj.gt.3302728; published online 9 February 2006

Several plants are used in folk medicine to treat gastrointestinal disorders. Ananas ananassoides(Baker) L.B.Smith (Family Bromeliaceae) is a medicinal plant commonly used in the central region of Brazil against gastric pain. Weevaluated two extracts (methanol [MeOH] and dichloromethane [DCM]) obtained from the leaves of A. ananassoidesfor theirability to protect the gastric mucosa against injuries caused by necrotizing agents (0.3 M HCl/60% ethanol, absolute ethanol,non-steroidal anti-inflammatory drugs, and pylorus ligation) in mice and rats. The best results were obtained after pretreat-ment with the DCM extract, whereas the MeOH extract did not show any significant anti-ulcerogenic activity but presentedmutagenic action. The mechanism of action of the DCM extract suggested the effective participation of endogenous sulfhydrylgroup in the gastroprotective action. The data, taken together with the absence of acute toxicity and mutagenicity, indicatethe apolar extract, instead of the polar, extract of A. ananassoides as a safe and potential new anti-ulcerogenic drug.

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.

IPTV 서비스는 기존 단방향 지상파 TV보다 다양한 채널의 다양한 콘텐츠를 제공하므로 사용자가 빠르고 쉽게 원하는 콘텐츠를 찾기 위한 개인화 IPTV 사용자 인터페이스 개발이 요구되고 있다. 하지만 기존의 연구는 단방향 TV 서비스 인터페이스를 그대로 이용하거나 단순 카테고리 별로 분류된 정보 제공에 머물러 개인화된 인터페이스로는 아직 미흡하다. 본 논문에서는 협력적 여과, 내용기반 여과 등 기존 개인화 추천 기법을 이용하여 사용자가 원하는 정보를 빠르게 제공하고, 사용자의 편의성을 증대하는 SmarTVi 인터페이스와 개인화된 검색 결과를 제공하는 검색 모듈 SmarTVi-Search를 제안한다.
