We studied a family with Gorlin-Goltz syndrome. The novel mutations of our cases were located on the 21st exon of the PTCH1 gene (c.3450C>G). The father, who received a strategic 56-day vismodegib treatment for disease control, was the first patient with Gorlin syndrome treated with the hedgehog inhibitor in Taiwan. The lesions regressed gradually, with scar formation, and were subsequently removed via a wide excision. Further details are provided below. (Ann Dermatol 30(5) 597∼601, 2018)

This study proposes an application of the classical rock mass classification concept on the estimation of in situ hydraulic conductivity of regolith and fractured bedrock which can be utilized to evaluate groundwater potential in mountainous areas. On the basis of boring logs, borehole televiewer image data, and double packer hydraulic test data conducted in the Basin of Jhuoshuei River of central Taiwan with the aid of bivariate analysis, two rock mass permeability classification systems (Hydro-Potential value for Regolith (HPR) and Hydro-Potential value for Bedrock (HPB) System) were developed. By regression analysis, the dependence of HPB/HPR on in situ hydraulic conductivity was performed, and two empirical models for estimating in situ hydraulic conductivity were derived. Meanwhile, two derived models were validated through the comparison against results from other types of hydraulic test data (pumping and single packer tests). Therefore, the development of the empirical models for a groundwater-related project enables to help the planning of detailed investigations for the determination of hydraulic conductivity with cost-effectiveness.

<P>Two new semiconducting polymers based on indacenodithiophene and thiadiazolo[3,4-<I>c</I>]pyridine units were synthesized <I>via</I> Stille coupling polymerization. The polymers, PIDTPyT and PIDTDTPyT, exhibited main absorption bands in the range of 550–800 nm while their absorption maxima were located at around 700 nm in films. With two additional thiophene spacers, PIDTDTPyT showed a broader absorption band but a 20 nm blue-shifted maximum peak compared to that of PIDTPyT. Both of the polymers possess low bandgaps (∼1.6 eV) and deep energy levels for both the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO). Organic field-effect transistors (OFETs) device measurements indicate that PIDTPyT and PIDTDTPyT have high hole carrier mobilities of 0.066 and 0.045 cm<SUP>2</SUP> V<SUP>−1</SUP> s<SUP>−1</SUP>, respectively, with the on/off ratio on the order of 10<SUP>6</SUP>. Bulk heterojunction photovoltaic devices consisting of the copolymers and PC<SUB>71</SUB>BM gave power conversion efficiencies (PCE) as high as 3.91% with broadband photo-response in the range of 300–800 nm.

<P>A detailed model study has shown that thin film morphology and bulk-heterojunction solar cell performance can be significantly improved by systematic tuning of the surface energy of the conjugated donor polymer through side-chain functionalization. Thiophene-flanked diketopyrrolopyrrole (DPP) moieties with different contents of cyanohexane side chains were incorporated into three low band-gap conjugated copolymers (<B>PIDTDPP1</B>, <B>PIDTDPP2</B> and <B>PIDTDPP3</B>) consisting of indacenodithiophene (IDT) donors and DPP acceptors. The resulting polymers possessed good solubility in common organic solvents and showed similar energy levels, bandgaps, and hole mobilities. However, the introduction of cyano groups onto the terminal of side-chains significantly changed their surface energy. Topographical images obtained from atomic force microscopy (AFM) proved that a better matched surface energy between polymer and PC<SUB>71</SUB>BM had led to enhanced miscibility, which resulted in better BHJ film morphology. Consistent with the surface energy enhancement, the performance of BHJ photovoltaic devices increased from 0.97% for <B>PIDTDPP1</B>, to 2.16% for <B>PIDTDPP2</B> then to 3.67% for <B>PIDTDPP3</B>. These results clearly reveal that tuning surface energy is an effective way to improve the morphology of the BHJ active layer and efficiency of the photovoltaic device.</P> <P>Graphic Abstract</P><P>We have shown that significantly improved thin film morphology and bulk-heterojunction solar cell performance can be achieved by systematically tuning the surface energy of conjugated polymer donors through side-chain functionalization. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c2jm15517f'> </P>

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.

Wecompared population suppression of the phytophagous mites, Tetranychus kanzawai Kishida and Panonychus citri (McGregor), on papaya by second instar larvae of the green lacewing, Mallada basalis (Walker), at various predator:prey release ratios in the laboratory. Initially, we presented M. basalis with mixed age classes of each mite species separately at a density of approximately 30 mites per seedling. After 3 days, predator:prey ratios of 1:30, 1:15, and 1:10 resulted in reductions of T. kanzawai of 66.8%, 82.6%, and 83.3%, respectively, and reductions of P. citri of 41.8%, 75.5%, and 77.2%, respectively. Predation on individual age classes was approximately equal in both species, reinforcing previous findings that this predator does not show a preference among age classes. We next presented M. basalis with mixed populations of the two mite species in which there were equal numbers of each species and the density was as in the single species tests. Total mite reduction with both mite species present was 48.5%, 71.9%, and 74.5% at ratios of 1:30, 1:15, and 1:10, respectively; T. kanzawai was reduced by 50.5%, 77.4%, and 79.5%, respectively, and P. citriwas reduced by 44.1%, 60.3%, and 63.2%, respectively. This study suggests that M. basalis has the potential for substantially suppressing populations of both T. kanzawai and P. citri on papaya at a predator:prey ratio of 1:15 or greater. However, evaluation under realistic agricultural settings is needed before specific recommendations about predator release rates can be made.

Exotoxins produced by Actinobacillus (A.) pleuropneumoniae(Apx) play major roles in the pathogenesis of pleuropneumoniain swine. This study investigated the role of ApxI in hemolysisand cellular damage using a novel apxIA mutant, ApxIA336,which was developed from the parental strain A. pleuropneumoniae serotype 10 that produces only ApxI in vitro. The genotype of ApxIA336 was confirmed by PCR, Southernblotting, and gene sequencing. Exotoxin preparation derivedfrom ApxIA336 was analyzed for its bioactivity towardsporcine erythrocytes and alveolar macrophages. Analysisresults indicated that ApxIA336 contained a kanamycinresistantcassette inserted immediately after 1005 bp of theapxIA gene. Phenotype analysis of ApxIA336 revealed nodifference in the growth rate as compared to the parentalstrain. Meanwhile, ApxI production was abolished in thebacterial culture supernatant, i.e. exotoxin preparation. Theinability of ApxIA336 to produce ApxI corresponded to the lossof hemolytic and cytotoxic bioactivity in exotoxin preparation,as demonstrated by hemolysis, lactate dehydrogenase release,mitochondrial activity, and apoptosis assays. Additionally, thevirulence of ApxIA336 appeared to be attenuated by 15-fold inBALB/c mice. Collectively, ApxI, but not other components inthe exotoxin preparation of A. pleuropneumoniae serotype 10,was responsible for the hemolytic and cytotoxic effects onporcine erythrocytes and alveolar macrophages.

Aims: The current study aims to elucidate the treatment efficacy (defined as undetectable HCV RNA throughout 12 weeks of post-treatment follow-up, SVR12) and safety DCV/ASV plus ribavirin for 12 weeks in HCV-1b patients without NS5A RAS. Methods: This is a single-arm, open-label phase 2 study. Seventy directly acting antivirals (DAA)-naïve HCV-1b patients without L31/Y93 RAS are planned to receive daclatasvir (60 mg/ day) and asunaprevir (100 mg twice daily) plus weight-based ribavirin (1000-1200 mg/day) for 12 weeks. After treatment they were followed up for 12 weeks. Results: As of 31 Oct 2017, 58 eligible patients are allocated to treatment, with a mean age of 59.3 years and female predominance (67.2%, 39/58). The mean HCV RNA was 5.87+0.77 log10 IU/mL; 23 patients (39.7 %) had significant hepatic fibrosis (>F2). In the modified intention-to-treat analysis, the rate of undetectable HCV at week 1, week 2, week 4, week 8 and endof- treatment was 25 % (14/56), 84.8 % (39/46), 100 % (46/46), 100 % (38/38) and 100 % (27/27), respectively. Undetectable HCV RNA were observed in all of the patients with HCV RNA assessable 4 weeks (SVR4, 18/18) and 12 weeks (SVR12, 12/12) post treatment. None of the 18 patients who completed the 12-week treatment experienced relapse during post-treatment follow-up. The most common adverse event was fatigue (78.3 %), followed by pruritus (65.2 %) and dizziness (52.2 %), of which were considered as ribavirin related. None of the participating subjects withdrew treatment or follow-up throughout the trial peroid. Three serious adverse events were reported which included urosepsis, appendicitis and left ureteral stone. All were unrelated to the investigating drugs. Conclusions: 12 weeks of DCV/ASV plus ribavirin was highly effective and safe in HCV-1b patients without NS5A RAS in the interim analysis. The satisfactory results would be anticipated in the full patient set.
