Published: June 2016

Introduction:Recurrent lower back pain (rLBP) and neuromuscular fatigue are independently thought to increase the risk of lower extremity (LE) injury. Volitional preemptive abdominal contraction (VPAC) is thought to improve lumbar spine and pelvis control in individuals with rLBP. The effects of VPAC on fatigued landing performance in individuals with rLBP are unknown.Objectives:To determine the effects of VPAC and LE fatigue on landing performance in a rLBP population.Design:Cross-sectional pretest-posttest cohort control design.Setting:A clinical biomechanics laboratory.Subjects:32 rLBP (age 21.2 ± 2.7 y) but without current symptoms and 33 healthy (age 20.9 ± 2.3 y) subjects.Intervention(s):(i) Volitional preemptive abdominal contraction using abdominal bracing and (ii) fatigue using submaximal free-weight squat protocol with 15% body weight until task failure was achieved.Main Outcome Measure(s):Knee and ankle angles, moments, electromyographic measurements from semitendinosus and vastus medialis muscles, and ground reaction force (GRF) were collected during 0.30 m drop-jump landings.Results:The VPAC resulted in significantly earlier muscle onsets across all muscles with and without fatigue in both groups (mean ± SD, 0.063 ± 0.016 s earlier; P ≤ .001). Fatigue significantly delayed semitendinosus muscle onsets (0.033 ± 0.024 s later; P ≤ .001), decreased GRF (P ≤ .001), and altered landing kinematics in a variety of ways. The rLBP group exhibited delayed semitendinosus and vastus medialis muscle onsets (0.031 ± 0.028 s later; P ≤ .001) and 1.8° less knee flexion at initial contact (P ≤ .008).Conclusion:The VPAC decreases some of the detrimental effects of fatigue on landing biomechanics and thus may reduce LE injury risk in a rLBP population.

Published: June 2016

Context:Whole-body vibration (WBV) is a type of weight-bearing exercise used in the field of sport and rehabilitation. There is no study on the effects of WBV on muscle recovery after a fatiguing activity.Objective:To determine the effects of a single WBV session on lower-extremity fatigue.Design:Randomized controlled pilot study.Setting:University Physiotherapy Clinic.Subjects:A total of 13 healthy young men volunteered to participate in this study. Subjects were randomly assigned into the WBV group (n = 7, mean age: 21 y) or control group (CG; n = 6, mean age: 20 y).Intervention:Subjects in the WBV group participated in a single-session WBV (30 Hz, amplitude 4 mm, 2 min) after lower-extremity fatigue.Main Outcome Measures:Peak force of quadriceps muscle, single leg hop test, and Y-test were measured before inducing muscle fatigue (T0), immediately after completing the fatigue protocol (T1), after WBV (T2), and 15 min following the application of WBV (T3). The same method was applied in the CG while the WBV machine was turned off.Results:Repeated-measure ANOVA revealed no significant differences between groups in any of the outcomes.Conclusions:The findings indicated that WBV was not effective in the recovery of lower-extremity fatigue in healthy young men.
Percutaneous endoscopic transgastric jejunostomy (PEG-J): a retrospective analysis on its utility in maintaining enteral nutrition after unsuccessful gastric feeding

Published: June 2016

Background/aimsAlthough percutaneous endoscopic gastrostomy (PEG) is the method of choice for long-term enteral nutrition, feeding-related adverse events such as aspiration pneumonia and peristomal leakage can impede the use of PEG. Percutaneous endoscopic transgastric jejunostomy (PEG-J) using large-bore jejunal tubes may help by circumventing gastric passage during enteral nutrition and improving drainage of gastric secretions.Methods20 patients (12 males and 8 females) who received PEG-J after unsuccessful PEG feeding during a 6-year period in our institution were analysed retrospectively to evaluate the efficacy of large-bore jejunal feeding tubes in maintaining enteral nutrition.ResultsThe median age was 83.5 (71–96) years. The median period between PEG and PEG-J was 33 (14–280) days. Indications were aspiration due to gastro-oesophageal reflux in 18 patients and severe peristomal leakage in 2 patients. Tube placements were successful in all patients. There were 6 (30%) in-hospital mortalities, with 3 (15%) occurring within 30 days after procedure.ConclusionsPEG-J can be performed safely in patients with PEG and may facilitate the maintenance of enteral nutrition in most of the patients. Patients with unsuccessful PEG feeding can be offered the option of jejunal feeding before considering termination of enteral nutrition.

Published: June 2016

With the help of photoluminescence Spectroscopy (PLS), we have investigated the optoelectronic properties of two different families of InAs quantum dashes (QDashes) grown on misoriented InP(001) substrate with 2[Formula: see text]off miscut angle toward the [110] direction (2[Formula: see text]F type). The lowest full width at half maximum (FWHM) of the PL spectrum measured at 12 K indicates the good self organization of InAs QDashes. The weak ratio of the integrated PL measured in 12–300 K temperature range denotes the good spatial confinement of the photogenerated carriers in InAs QDashes. The fast redshift of the PL peaks energy and the anomalous decrease of the FWHM with the increase of the temperature are attributed to an efficient thermal relaxation process of photogenerated carriers in the vicinal sample. This result is highlighted with the help of theoretical modeling of the PL peak energy as a function of the temperature, using three models (Varshni, “Vina, Logothetidis and Cardona” and Pässler). From experimental and theoretical results, we have evidenced the contribution of longitudinal acoustic-phonons (LA-phonons) in the PL of InAs/InP QDashes, via the deformation potential, especially in high temperatures range. We have attributed this behavior to the strained InAs/InP QDashes and/or to the topography of the vicinal InP(001) substrate which favors the presence of stepped phonons polarized along the steps. These vibrational modes can further interact with the excitons at high temperatures. The measured thermal activation energies of each family of InAs QDashes demonstrate that the InAs wetting layer act as a barrier for the thermoionic emission of photogenerated carriers. This result confirms the good spatial confinement of excitons in this sample.

Published: June 2016

We report a systematic study of large-scale growth of high-quality WSe2 atomic layers directly on SiO2/Si substrates using a convenient method. Various parameters, especially growth temperatures, flow rate of carrier gas and tube pressure, are investigated in affecting the properties of as-grown WSe2 flakes in terms of their sizes, shapes and thickness. The pre-annealing step is demonstrated to be a key role in achieving the large-scale growth. Under an optimized condition, the lateral size of triangular single-crystal monolayer WSe2 is up to 30 [Formula: see text]m and the area of the monolayer thin film can be up to 0.25 mm2. And some other interesting features, such as nanoflowers, are observed, which are a promising for catalyzing research. Raman spectrum and microphotoluminescence indicate distinct layer dependent efficiency. Auger electron spectroscopy (AES) studies demonstrate the atomic concentration of the as-grown WSe2. Electrical transport further shows that the [Formula: see text]-type WSe2 field-effect transistors exhibit excellent electrical properties with carrier mobility of [Formula: see text][Formula: see text]64 cm[Formula: see text]V[Formula: see text]s[Formula: see text] and current on/off ratio over 105. These results are comparable to the exfoliated materials.

Published: June 2016

In this work, vitreous samples were prepared in two series by normal melt-quenching technique and under controlled conditions. The amorphous nature of specimens was confirmed using XRD spectra. To perform FT-IR and UV-vis studies, the thin blown films were also prepared. Different ratios of transition metals are assumed to cause depolymerization of the phosphate glass network. Infrared spectra showed absorption bands related to characteristic bonds of phosphate. The P=O bond at about 1200 cm[Formula: see text] was observed, as a direct consequence of meta-phosphate bond group. The almost unchanged peak position and intensity of P=O bond (in the presence of two transition metal ions) indicated the glass modifying nature of transition metal oxides (TMOs). The spectra of two series are almost identical, except for 890–1100 cm[Formula: see text] range, which can be attributed to presence of second TMO in the first glass series. UV-vis spectra also showed that the absorption edge, optical band gap and Urbach energy of the prepared samples are highly dependent on the kind and percentage of their reagents. The most striking result of UV-vis measurements was increasing and decreasing of optical band gap in the first and the second series with MoO3 content, respectively. The shape of the absorption edge (a plot of [Formula: see text] versus [Formula: see text]) demonstrated the indirect nature of the band gap in the prepared specimens.

SummaryWe investigated three-month clinical outcomes in patients with venous thromboembolism (VTE) treated with rivaroxaban or conventional anticoagulation in routine clinical practice. Between November 2012 and February 2015, 2,062 consecutive patients with VTE from 11 acute care hospitals in Switzerland were enrolled in the SWIss Venous ThromboEmbolism Registry (SWIVTER). Overall, 417 (20 %) patients were treated with rivaroxaban. In comparison to 1,645 patients on conventional anticoagulation, patients on rivaroxaban were younger (56 ± 18 vs. 65 ± 17 years; p<0.001), less often had pulmonary embolism (38 % vs 66 %; p<0.001), hypertension (26 % vs 41 %; p<0.001), cancer (10 % vs 28 %; p<0.001), congestive heart failure (10 % vs 17 %; p=0.001), diabetes (8 % vs 15 %; p<0.001), chronic lung disease (7 % vs 13 %; p=0.001), renal insufficiency (7 % vs 13 %; p=0.001), recent surgery (7 % vs 14 %; p<0.001), and acute coronary syndrome (1 % vs 4 %; p=0.009). VTE reperfusion therapy was more frequently used (28 % vs 9 %; p<0.001) and indefinite-duration anticoagulation treatment less often planned (26 % vs 39 %; p<0.001), respectively. In the propensity score-adjusted population, the risk of recurrent VTE was similar in patients on rivaroxaban vs conventional anticoagulation (1.2 % vs 2.1 %, hazard ratio [HR] 0.55, 95 % confidence interval [CI] 0.18–1.65; p=0.29); the risk of major bleeding was also similar, respectively (0.5 % vs 0.5 %, HR 1.00, 95 %CI 0.14–7.07; p=1.00). Conventional anticoagulation is still frequently used for the treatment of VTE, particularly in the elderly and those with comorbidities. Early clinical outcomes were comparable between propensity score-adjusted patient populations on rivaroxaban and conventional anticoagulation.

Authors: Khot Mayura 
Published: June 2016

The present work was carried out in Malgaon-Bagayat (16009’04.35”N & 73033’04.7”E) and Malvan Taluka (16005’00”N & 73030’00”E) of Sindhudurg District. The paper represents the first document on birds as there are no published records from Sindhudurg District. The study was conducted for a period of two years to explore the avifauna as no records have been published yet from this area. A total of 101 species of birds belonging to 17 orders and 45 families and were recorded in the study areas inhabiting different types of habitats. The Order Passeriformes contributed the maximum species (44.9%) followed by Pelecaniformes (9.2%), Charadriiformes (8.2%) and Accipitriformes (6.1%). The species such as the Asian Paradise Flycatcher, Common Hoopoe, and Pied Kingfisher were observed only once in the study area. The common occurrence of the Near Threatened Malabar Pied Hornbill in Bagayat signifies the ornithological importance of this site. Long-term studies on distribution and abundance are required to prepare a conservation plan for avifauna in Sindhudurg District. The data generated can be considered as baseline data for future conservation and management of existing species.
Egg parasitoids from the subfamily Scelioninae (Hymenoptera: Platygastridae) in irrigated rice ecosystems across varied elevational ranges in southern India.
Authors: Shweta M , Rajmohana K. 
Published: June 2016

Platygastridae (Hymenoptera) is the most abundant family of parasitic Hymenoptera in rice ecosystems in southern India. Members belonging to the subfamily Scelioninae were assessed in rice ecosystems along three elevation ranges, a highland (737m), midland (54m) and lowland (1.5m) in northcentral Kerala (southern India) during the pre-flowering to the milky-grain stage of paddy. Malaise traps were employed as the standard specimen collection methodology with collections made for four weeks, using two malaise traps per field, from August 2008 to January 2009, serviced once a week. The study recorded a total of 198 individuals belonging to 38 species in 21 genera. The species diversity, richness, evenness as well as beta diversity were computed for the three sites along with ANOVA and it was concluded that, contrary to other studies on different taxa, elevation did not have any major effect on the overall diversity patterns in Platygastridae even though there was a difference in species assemblages.
Low genetic diversity in Clarias macrocephalus Günther, 1864 (Siluriformes: Clariidae) populations in the Philippines and its implications for conservation and management

Published: June 2016

Clarias macrocephalus Günther, 1864 is a Near Threatened freshwater catfish found in the Philippines and other Southeast Asian countries. Its numbers have dwindled over the past few years because of habitat loss and competition. This study examined the genetic diversity of the remaining viable populations of C. macrocephalus in the Philippines. Primers were designed to amplify via polymerase chain reaction (PCR) the complete mitochondrial DNA (mtDNA) control region (870-bp) in 120 specimens collected from three sites: (1) Buguey, Cagayan; (2) Camalaniugan, Cagayan; and (3) Agusan del Sur. Of the 120 sequences generated, only three haplotypes and two polymorphic sites were found. Overall haplotype and nucleotide diversity (h=0.479, π=0.00058) were alarmingly low, consistent with populations of other freshwater fishes that have experienced a genetic bottleneck. The overall FST value was 0.80050, indicative of large genetic differentiation between populations. The very low genetic variation found in all three C. macrocephalus populations calls for conservation and management efforts for the protection of the remaining populations of this economically important species.
The Nilgiri Tahr (Mammalia: Cetartiodactyla: Bovidae: Nilgiritragus hylocrius Ogilby, 1838) in the Agastyamalai range, Western Ghats, India: population status and threats

Published: June 2016

The Nilgiri Tahr (Nilgiritragus hylocrius Ogilby, 1838) has not been comprehensively surveyed in the southern Western Ghats, India. Here we present results of a survey conducted in 2012 and 2013 in 25 sites where Nilgiri Tahr was reported in Agastyamalai range south of the Shencottah gap. The objectives of the survey were to assess population status; evaluate threats and propose conservation measures. In each site the geographical coordinates were noted. If Nilgiri Tahr (=Tahr) were sighted, the number and herd structure were recorded. Indirect signs of Tahr presence such as faecal pellets and feedback from local informants were noted in sites with no direct sightings of Tahr. The total sightings were 247 Tahr in 10 sites, and indication of Tahr presence in seven sites. Only two populations viz. Kalamalai-Varraiattumudi and Muthukulivayal-Balamore were large (>30 individuals). Tahr were not present in eight sites: of which four had earlier records of Tahr presence, and the other four had no prior data. There was a significant positive association between percentage of young (kids and yearlings) and number of Tahr sighted. Illegal hunting was widespread in the past, and continues to be a serious threat. Loss of Tahr grazing habitat to successional processes resulting in increased tree cover, is a long term threat that could increase with climate change. A landscape level management plan to reconnect small populations, rehabilitate Tahr in sites where they have disappeared, use fire to restore short grass habitats, and stringent curb on illegal hunting is required for the long term viability of the Nilgiri Tahr in this region.

All that glitters is not gold: A projected distribution of the endemic Indian Golden Gecko Calodactylodes aureus (Reptilia: Squamata: Gekkonidae) indicates a major range shrinkage due to future climate change.
Authors: Srinivasulu Aditya , Srinivasulu Chelmala 
Published: June 2016

Climate change has a perceived threat on biodiversity due to its effect on species range. Species with narrow ranges and highly specific climatic and habitat requirements are at higher risk. To understand the influence of climate change on the Indian endemic gekkonid, the Indian Golden Gecko Calodactylodes aureus (Beddome, 1870) we model the present and future predicted distribution (2050 and 2070) under the CMIP5 RCP4.5 and RCP8.5 scenarios using MaxEnt under the HadGEM3-ES Model. Our analysis revealed the negative impact of climate change on the Indian Golden Gecko with a decrease in the amount of climatically suitable areas in the future, and an almost total range shrinkage by 2070. Despite its wide distribution in the eastern Deccan Peninsula, according to our predictions, the species is threatened by a shrinkage in the future range due to climate change.

Description of fourty four new species, taxonomic notes and identification key to Neotropical Trichomyia Haliday in Curtis (Diptera: Psychodidae, Trichomyiinae)
Authors: ARAÚJO MAÍRA XAVIER , BRAVO FREDDY 
Published: June 2016

Trichomyia Haliday in Curtis is distributed worldwide, except in Antarctica. The Neotropical region has the greatest known species richness of Trichomyia, with 76 described species, compared with five in the Nearctic region, nine in the Palearctic, five in the Afrotropical region, six in the Oriental region, and 46 in the Australasian region. Two morphological groups within the genus have been previously recognized: Group A, comprising species with four clearly differentiated palpus segments; and Group B, comprising species with three palpus segments, as well as a group of species with four palpus segments but with the two basal segments not fully articulated (partially fused). We examined 1,330 specimens of Trichomyia that were collected almost exclusively from Brazil, specifically from the states of Amazonas, Pará, Bahia, Roraima, Rondônia, and Minas Gerais. 44 new species have been identified, representing an increase of 37% for this genus in the Neotropical region. In order to facilitate their study, some species are placed in provisional morphological groups. The distributions of five species of Trichomyia are expanded and a key to the males of Neotropical species is presented.
