Effects of prolonged immunocontraception on the breeding behavior of American bison

In late 2009, the Catalina Island Conservancy began using fertility control to replace periodic removals to manage an introduced population of American bison (Bison bison) on the island. Through the application of the immunocontraceptive vaccine porcine zona pellucida (PZP), population growth was slowed within 1 year, and halted over time. In response to lingering questions about the use of PZP to manage large, free-ranging wildlife populations, we sought to determine the reversibility of PZP by ceasing the annual application to a subset of 15 bison cows and monitoring for subsequent calf arrival, and to document changes in the timing and length of the breeding season in response to PZP by monitoring breeding behavior and assessing fecal progesterone (FP) levels for all 60 resident cows over a 13-month period. As of June 2017, no new calves had been observed on the island, suggesting that, following repeated annual treatment with PZP (3 or 4 years), bison do not resume normal reproduction for at least 4 or 5 years, and that fewer treatments would be advisable if a faster return to fertility is desired. Based on observations of bull and cow behavior, and FP levels, cows displayed estrous cycles consistently throughout the study period, indicating that bison may ovulate year-round when conception and its consequences, e.g., lactation and presence of calves, are blocked. Because there is little evidence that an extended breeding season would negatively impact the health of bulls or result in large numbers of out-of-season births on Catalina, PZP appears to be a highly effective tool for managing the population of introduced bison on the island. However, the extended period of contraception and breeding activity of both cows and bulls may make PZP less suitable in high-latitude, predator-rich environments where bison conservation remains a top priority.
Defining conservation priorities for freshwater fishes according to taxonomic, functional, and phylogenetic diversity

To date, the predominant use of systematic conservation planning has been to evaluate and conserve areas of high terrestrial biodiversity. Although studies in freshwater ecosystems have received recent attention, research has rarely considered the potential trade-offs between protecting different dimensions of biodiversity and the ecological processes that maintain diversity. We provide the first systematic prioritization for freshwaters (focusing on the highly threatened and globally distinct fish fauna of the Lower Colorado River Basin, USA) simultaneously considering scenarios of: taxonomic, functional, and phylogenetic diversity; contemporary threats to biodiversity (including interactions with nonnative species); and future climate change and human population growth. There was 75% congruence between areas of highest conservation priority for different aspects of biodiversity, suggesting that conservation efforts can concurrently achieve strong complementarity among all types of diversity. However, si.
Direct-To-Consumer Telehealth May Increase Access To Care But Does Not Decrease Spending.

The use of direct-to-consumer telehealth, in which a patient has access to a physician via telephone or videoconferencing, is growing rapidly. A key attraction of this type of telehealth for health plans and employers is the potential savings involved in replacing physician office and emergency department visits with less expensive virtual visits. However, increased convenience may tap into unmet demand for health care, and new utilization may increase overall health care spending. We used commercial claims data on over 300,000 patients from three years (2011-13) to explore patterns of utilization and spending for acute respiratory illnesses. We estimated that 12 percent of direct-to-consumer telehealth visits replaced visits to other providers, and 88 percent represented new utilization. Net annual spending on acute respiratory illness increased $45 per telehealth user. Direct-to-consumer telehealth may increase access by making care more convenient for certain patients, but it may also increase utilization and health care spending.
Early Development of Functional Network Segregation Revealed by Connectomic Analysis of the Preterm Human Brain

Abstract Human brain functional networks are topologically organized with nontrivial connectivity characteristics such as small‐worldness and densely linked hubs to support highly segregated and integrated information processing. However, how they emerge and change at very early developmental phases remains poorly understood. Here, we used resting‐state functional MRI and voxel‐based graph theory analysis to systematically investigate the topological organization of whole‐brain networks in 40 infants aged around 31 to 42 postmenstrual weeks. The functional connectivity strength and heterogeneity increased significantly in primary motor, somatosensory, visual, and auditory regions, but much less in high‐order default‐mode and executive‐control regions. The hub and rich‐club structures in primary regions were already present at around 31 postmenstrual weeks and exhibited remarkable expansions with age, accompanied by increased local clustering and shortest path length, indicating a transition from a relatively random to a more organized configuration. Moreover, multivariate pattern analysis using support vector regression revealed that individual brain maturity of preterm babies could be predicted by the network connectivity patterns. Collectively, we highlighted a gradually enhanced functional network segregation manner in the third trimester, which is primarily driven by the rapid increases of functional connectivity of the primary regions, providing crucial insights into the topological development patterns prior to birth.
Influence of surface based cohesive parameters on static performance of concrete composite T-shaped beams

The study presented constitutes the next step of authors’ investigations on the concrete composite T-shaped beams. The comparison of the failure modes and crack patterns of numerical models and beams tested was performed previously. In this paper, analyses concentrate on determination the proper values of cohesive surface parameters ensuring the high conformity of deformation and strains of the numerical model to the experimental results. In the particular series of beams the interfaces between concrete parts are varied as follows: reinforced joint with normal and tangential interactions only (BZ/S2/A), non-reinforced joint with adhesion (BZ/P), and reinforced joint with adhesion (BZ/P+S). Material properties used in numerical model are based on obtained in the laboratory ones. Furthermore, the ‘traction–separation’ law in the ABAQUS software defining the cohesion surface is used and analysis of the cohesive parameters response to interface roughness is carried out. The results show a strong dependence between the cohesion surface parameters and the response of the composite beam. A very good convergence of the numerical model with the experimental results in terms of ‘force-displacement’ relationship is achieved. Finally the parameters defined in the ABAQUS are determined, which have a key impact on the beams response.
Semantic Single-Image Dehazing

Single-image haze-removal is challenging due to limited information contained in one single image. Previous solutions largely rely on handcrafted priors to compensate for this deficiency. Recent convolutional neural network (CNN) models have been used to learn haze-related priors but they ultimately work as advanced image filters. In this paper we propose a novel semantic ap- proach towards single image haze removal. Unlike existing methods, we infer color priors based on extracted semantic features. We argue that semantic context can be exploited to give informative cues for (a) learning color prior on clean image and (b) estimating ambient illumination. This design allowed our model to recover clean images from challenging cases with strong ambiguity, e.g. saturated illumination color and sky regions in image. In experiments, we validate our ap- proach upon synthetic and real hazy images, where our method showed superior performance over state-of-the-art approaches, suggesting semantic information facilitates the haze removal task.
Rho kinase regulates neurite outgrowth of hippocampal neurons via calcium dependent cytoskeleton regulation.

OBJECTIVE To investigate whether calcium is involved in downstream signal transduction in neurite outgrowth regulated by Rho kinase. METHODS In vitro primary hippocampal neurons were cultured and treated with Rho kinase agonist (LPA) or antagonist (Y-27632). Then, the cytoskeleton and neurite outgrowth were observed. After addition of calcium antagonist BAPTA/AM to reduce intracellular calcium, the cytoskeleton distribution and neurite outgrowth were observed. RESULTS The activation or inhibition of Rho kinase could significantly alter the number and length of neurites of hippocampal neurons. Rho kinase regulated the cytoskeleton to regulate the neurite outgrowth, and LPA could significantly increase intracellular calcium. After BAPTA/AM treatment, the length and branch number of neurites of neurons reduced markedly. BAPTA/AM was able to reduce intracellular calcium and decrease neuronal cytoskeleton. Treatment with both BAPTA/AM and LPA could stop the retraction of neurites, but the length and branch number of neurites remained unchanged after treatment with Y-27632 and LPA. CONCLUSION Calcium may affect the cytoskeleton arrangement to regulate neurite outgrowth, and calcium is involved in the downstream signal transduction of Rho kinase regulated neurite outgrowth of hippocampal neurons.
Association between serum soluble CD14 and IL‐8 levels and clinical outcome in primary biliary cholangitis

Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by portal inflammation and immune‐mediated destruction of intrahepatic bile ducts that often leads to liver decompensation and liver failure. Although the biochemical response to ursodeoxycholic acid (UDCA) can predict disease outcome in PBC, few biomarkers have been identified as prognostic tools applicable prior to UDCA treatment. We therefore sought to identify such indicators of long‐term outcome in PBC in the Japanese population.
Analgesic effects of lidocaine-ketorolac compared to lidocaine alone for intravenous regional anesthesia

Background: Intravenous regional anesthesia is a simple and reliable method for upper extremity surgery. In order to increase the quality of blocks and reduce the amount of pain, many drugs are used with lidocaine. In this study, the effect of ketorolac-lidocaine in intravenous regional anesthesia was investigated. Methods: 40 patients undergoing elective upper limb with America Society of Anesthesiologists class I and II were selected and randomly divided into two groups. The first group of 20 patients received 200 mg of lidocaine, and the second group, 200 mg of lidocaine with 20 mg of ketorolac. In both groups, the drug was diluted to 40 ml. In both groups, the onset of sensory block, onset of tourniquet pain, the onset of pain after opening the tourniquet, score of postoperative pain and analgesic prescription in the first 24 hours, during 1, 6, 12 and 24 hours were studied. A measure of the quality of analgesia was evaluated by VAS. Results: The mean onset of tourniquet pain in the two groups was not significantly different (P=0.443). In the ketorolac group, the onset of pain after opening the tourniquet was significantly longer than lidocaine group (p<0.001). The mean postoperative pain score during the first 24 hours after surgery in the ketorolac group was significantly lower than lidocaine group (p<0.001). The average number of analgesia prescription during the 24 hours after operation was significantly lower in ketorolac group than lidocaine group (p<0.001). Conclusions: Adding ketorolac to lidocaine for regional anesthesia can reduce the postoperative pain for up to 24 hours after opening the tourniquet.
Physical Responses of Convective Heavy Rainfall to Future Warming Condition: Case Study of the Hiroshima Event

An extreme precipitation event happened at Hiroshima in 2014. Over 200 mm of total rainfall was observed on the night of August 19th, which caused floods and many landslides. The rainfall event was estimated to be a rare event happening once in approximately 30 years. The physical response of this event to the change of the future atmospheric condition, which includes a temperature increase on average and convective stability change, is investigated in the present study using a 27-member ensemble experiment and pseudo global warming downscaling method. The experiment is integrated using the Japan Meteorological Research Institute non-hydrostatic regional climate model. A very high-resolution horizontal grid, 500 m, is used to reproduce dense cumulonimbus cloud formation causing heavy rainfall in the model. The future climate condition determined by a higher greenhouse gas concentration is prescribed to the model, in which the surface air temperature globally averaged is 4 K warmer than that in the preindustrial era. The total amounts of precipitation around the Hiroshima area in the future experiments are closer to or slightly lower than in the current experiments in spite of the increase in water vapor due to theatmospheric warming. The effect of the water vapor increase on extreme precipitation is found to be canceled out by the suppression of convection due to the thermal stability enhancement. The fact that future extreme precipitation like the Hiroshima event is not intensified is in contrast to the well-known result that extreme rainfall tends to be intensified in the future. The results in the present study imply that the response of extreme precipitation to global warming differs for each rainfall phenomenon.
Clinical application of the sinus tarsi approach in the treatment of intra-articular calcaneal fracture

Abstract To observe the clinical outcome of the sinus tarsi approach in the operative treatment of intra-articular calcaneal fractures. Forty-nine intra-articular calcaneal fractures in 45 patients were managed surgically with sinus tarsi approach. The anatomical plate and compression bolts were applied in 14 feet. The anatomical plate and screws were applied in 35 feet. Maryland foot score system was used to evaluate the function of the hindfoot at the followup. The reduction of the posterior facet was graded as nearly anatomical (less than 2 mm articular displacement) in 46 feet (93.9%). The width, height, and Böhler angle were significantly improved in all patients (P < .01). After a mean follow-up period of 18.7 months (14.5–29 months), the Maryland foot scores were: 34 feet scored 90–100 points (excellent), 6 feet scored 80–90 points (good), 6 feet scored 70–80 points (fair), and 3 feet scored 60–70 points (poor). Incision-edge necrosis occurred in 2 cases. One case suffered from incomplete medial plantar nerve injury. One case suffered from heel pad branch of the tibial nerve injury. Six cases suffered from sural nerve injury, and 4 cases sustained a lateral wound dehiscence due to a hematoma. No case suffered from lateral impingement syndrome. Up to now, no patient had to accept subtalar arthrodesis. Sinus tarsi approach provides good exposure to the subtalar joint. Open reduction and internal fixation of calcaneus fractures through a sinus tarsi approach allows adequate reduction with low risk of wound-healing complications.
Can disorder act as a chemical pressure? An optical study of the Hubbard model

The optical properties have been studied using the dynamical mean-field theory on a disordered Hubbard model. Despite the fact that disorder turns a metal to an insulator in high dimensional correlated materials, we notice that it can enhance certain metallic behavior as if a chemical pressure is applied to the system resulting in an increase of the effective lattice bandwidth (BW). We study optical properties in such a scenario and compare results with experiments where the BW is changed through isovalent chemical substitution (keeping electron filling unaltered) and obtain remarkable similarities vindicating our claim. We also make the point that these similarities differ from some other forms of BW tuned optical effects.
Similarity of babbling in Spanish- and English-learning babies

ABSTRACT Infants from a variety of linguistic backgrounds have been reported to babble similarly. The present study considers this possibility in detail, offering a concrete characterization of how babbling of Spanish- and English-learning babies is similar. Babbling of a group of Spanish- and another of English-learning infants (12 months of age) was recorded and transcribed by two experimenters, one a primarily Spanish speaker and one a primarily English speaker. Results show that in spite of gross phonetic differences between the adult phonologies of Spanish and English, babies from both groups produce predominantly CV syllables with voiceless, unaspirated plosive consonants. Vowel production is also perceived as notably alike. In the light of such similarities, possible differences in babbling of the two groups may be hard for even sophisticated listeners to notice.
[Molecular typing of Leishmania (Leishmania) amazonensis and species of the subgenus Viannia associated with cutaneous and mucosal leishmaniasis in Colombia: A concordance study].

INTRODUCTION Multilocus enzyme electrophoresis (MLEE) is the reference standard for the characterization of Leishmania species. The test is restricted to specialized laboratories due to its technical complexity, cost, and time required to obtain results. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) is used to identify Leishmania species. OBJECTIVE To establish the concordance between the two tests as identifying methods for circulating species in Colombia. MATERIALS AND METHODS A total of 96 isolates from patients with cutaneous or mucosal leishmaniasis were selected and identified by MLEE and PCR-RFLP with miniexon and hsp70 as the molecular targets, which were used sequentially. Restriction enzymes HaeIII and BccI were similarly applied. Cohen's kappa coefficient and the 95% confidence interval (CI) were calculated. RESULTS The kappa coefficient and the 95% CI between MLEE and PCR-RFLP displayed "very good" concordance with a coefficient of 0.98 (CI95%: 0.98 to 1.00). The identified species were Leishmania Viannia braziliensis, Leishmania Viannia panamensis, Leishmania Viannia guyanensis and Leishmania Leishmania amazonensis. A total of 80 of the 96 isolates were sequenced and the results obtained by PCR-RFLP were confirmed. CONCLUSION Due to the concordance obtained between tests results with the amplification of the genes miniexon and hsp70, PCR-RFLP is proposed as an alternative for identifying circulating Leishmania species in Colombia.
Incomplete resection rate of cold snare polypectomy: a prospective single-arm observational study

Abstract Background and study aims Cold snare polypectomy (CSP) is considered to be safe for the removal of subcentimeter colorectal polyps. This study aimed to determine the rate of incomplete CSP resection for subcentimeter neoplastic polyps at our center. Patients and methods Patients with small or diminutive adenomas (diameter 1 – 9 mm) were recruited to undergo CSP until no polyp was visible. After CSP, a 1 – 3 mm margin around the resection site was removed using endoscopic mucosal resection. The polyps and resection site marginal specimens were microscopically evaluated. Incomplete resection was defined as the presence of neoplastic tissue in the marginal specimen. We also calculated the frequency at which the polyp lateral margins could be assessed for completeness of resection. Results A total of 307 subcentimeter neoplastic polyps were removed from 120 patients. The incomplete resection rate was 3.9 % (95 % confidence interval [CI] 1.7 % – 6.1 %); incomplete resection was not associated with polyp size, location, morphology, or operator experience. The polyp lateral margins could not be assessed adequately for 206 polyps (67.1 %). Interobserver agreement between incomplete resection and lateral polyp margins that were inadequate for assessment was poor (κ = 0.029, 95 %CI 0 – 0.04). Female sex was an independent risk factor for incomplete resection (odds ratio 4.41, 95 %CI 1.26 – 15.48; P = 0.02). Conclusions At our center, CSP resection was associated with a moderate rate of incomplete resection, which was not associated with polyp characteristics. However, adequate evaluation of resection may not be routinely possible using the lateral margin from subcentimeter polyps that were removed using CSP.

Management of Blueberry Maggot With High Temperatures

Abstract High temperatures were investigated to manage blueberry maggot (Rhagoletis mendax Curran; Diptera:Tephritidae) in field and postharvest situations. To estimate lethal combinations of high temperatures/duration of exposure, blueberry maggot pupae were immersed in water at various temperatures during either 1 or 30 s in the laboratory. Treatments such as 70°C (1 s) or 55°C (30 s) caused 100% mortality of blueberry maggot pupae. In a lowbush blueberry field, soil temperatures at 0, 1, 2, 3, 4, and 5 cm depth were measured with thermocouples following the passage of a flamethrower attached to a tractor in the fall. While the temperatures reached up to ca. 80°C for ca. 1 s at the soil surface, they were <10°C at depths of 3, 4, and 5 cm. In field situations, the energy required to kill all pupae would be expensive to deliver with a flamethrower and this would also cause environmental concerns. An example of application concerning the use of high temperatures in a postharvest situation is discussed, notably immersion of reusable containers in hot water in compliance with Canadian Food Inspection Agency Directive D-02-04 (2015) to prevent dissemination of R. mendax in uninfested areas.
Interspecific competition promotes habitat and morphological divergence in a secondary contact zone between two hybridizing songbirds

Interspecific competition is assumed to play an important role in the ecological differentiation of species and speciation. However, empirical evidence for competition's role in speciation remains surprisingly scarce. Here, we studied the role of interspecific competition in the ecological differentiation and speciation of two closely related songbird species, the Common Nightingale (Luscinia megarhynchos) and the Thrush Nightingale (Luscinia luscinia). Both species are insectivorous and ecologically very similar. They hybridize in a secondary contact zone, which is a mosaic of sites where both species co‐occur (syntopy) and sites where only one species is present (allotopy). We analysed fine‐scale habitat data for both species in both syntopic and allotopic sites and looked for associations between habitat use and bill morphology, which have been previously shown to be more divergent in sympatry than in allopatry. We found that the two nightingale species differ in habitat use in allotopic sites, where L. megarhynchos occurred in drier habitats and at slightly higher elevations, but not in syntopic sites. Birds from allotopic sites also showed higher interspecific divergence in relative bill size compared to birds from syntopic sites. Finally, we found an association between bill morphology and elevation. Our results are consistent with the view that interspecific competition in nightingales has resulted in partial habitat segregation in sympatry and that the habitat‐specific food supply has in turn very likely led to bill size divergence. Such ecological divergence may enhance prezygotic as well as extrinsic postzygotic isolation and thus accelerate the completion of the speciation process.
