Musca domestica is one of the most important pests of human health, and has developed strong resistance to many chemicals used for its control. One important approach for creating new pesticides is the exploration of novel compounds from plants. During a wide screening of plants with insecticidal properties that grow in southern China, we found that the methanolic extracts of Myrsine stolonifera had insecticidal activity against the adults of M. domestica. However, the insecticidal constituents and mechanisms of the M...

Hymenopteran species in which sex is determined through a haplo-diploid mechanism known as complementary sex determination (CSD) are vulnerable to a unique form of inbreeding depression. Diploids heterozygous at one or more CSD loci develop into females but diploids homozygous at all loci develop into diploid males, which are generally sterile or inviable. Species with multiple polymorphic CSD loci (ml-CSD) may have lower rates of diploid male production than species with a single CSD locus (sl-CSD), but it is not clear if polymorphism is consistently maintained at all loci...

In order to investigate the sleep quality and influencing factors in patients with Parkinson's disease (PD), 201 PD patients were enrolled and underwent extensive clinical evaluations. Subjective sleep evaluation was assessed using the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). It was found that poor sleep quality (77.11%) and excessive daytime sleepiness (32.34%) were commonly seen in PD patients and positively correlated with disease severity. Then 70 out of the 201 PD patients and 70 age- and sex-matched controls underwent a polysomnographic recording...

BACKGROUND: Evidence suggests treadmill training (TT) and body-weight supported treadmill training (BWSTT) are effective strategies to improve gait in Parkinson's disease (PD) patients. However, few researchers have investigated the spatiotemporal parameters during TT or BWSTT. OBJECTIVE: The goal of this study is to determine gait adaptations in PD and healthy subjects during positive pressure BWSTT and post-intervention overground walking. METHODS: Ten PD and ten healthy individuals participated in this study...

We study the band discontinuity at the GaN/single-layer (SL) WSe2 heterointerface. The GaN thin layer is epitaxially grown by molecular beam epitaxy on chemically vapor deposited SL-WSe2/c-sapphire. We confirm that the WSe2 was formed as an SL from structural and optical analyses using atomic force microscopy, scanning transmission electron microscopy, micro-Raman, absorbance, and micro-photoluminescence spectra. The determination of band offset parameters at the GaN/SL-WSe2 heterojunction is obtained by high-resolution x-ray photoelectron spectroscopy, electron affinities and the electronic bandgap values of SL-WSe2 and GaN...

INTRODUCTION: Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommend vitamin D supplementation in hemodialyzed patients to monitor 25(OH)-vitamin D 25(OH)D levels. However, patient-to-patient inconsistency can be observed in response to the treatment. In this study, we aimed to evaluate the impact of the dialysis membrane on 25(OH)D, albumin (Alb) and vitamin D-binding protein (VDBP), the major players of vitamin D transport and storage. MATERIAL AND METHODS: Alb (Cobas), VDBP (R&D) and 25(OH)D (liquid chromatography-tandem mass spectrometry) were measured in 75 patients before and after a 4-hour dialysis session...

Mohammad Ehsanul Karim, Robert W Platt
Correct specification of the inverse probability weighting (IPW) model is necessary for consistent inference from a marginal structural Cox model (MSCM). In practical applications, researchers are typically unaware of the true specification of the weight model. Nonetheless, IPWs are commonly estimated using parametric models, such as the main-effects logistic regression model. In practice, assumptions underlying such models may not hold and data-adaptive statistical learning methods may provide an alternative...

Post-fire management can have an additional impact on the ecosystem; in some cases, even more severe than the fire. Salvage logging (SL) is a common practice in most fire-affected areas. The management of burnt wood can determine microclimatic conditions and seriously affect soil properties. In some cases, the way of doing it, using heavy machinery, and the vulnerability of soils to erosion and degradation can make this management potentially aggressive to soil. Research was done in "Sierra de Mariola Natural Park" (E Spain)...

Rifaximin is a BCS class IV (low-solubility, low-permeability) drug and also a P-gp substrate. The aims of this work were to assess the efficiency of different rifaximin amorphous solid dispersion (ASDs) formulations in achieving and maintaining supersaturation and to investigate the consequent solubility-permeability interplay. Spray-dried rifaximin ASDs were prepared with different hydrophilic polymers and their ability to achieve and maintain supersaturation was assessed. Then, rifaximin's apparent intestinal permeability was investigated as a function of increasing supersaturation both in vitro using the parallel artificial membrane permeability assay (PAMPA) and in vivo using the single-pass rat intestinal perfusion (SPIP) model...

Replication of linear chromosomes is facilitated by firing of multiple replication origins that ensures timely duplication of the entire chromosome. The Smc5/6 complex is thought to play an important role in replication by its involvement in the restart of collapsed replication forks. Here, we present genetic evidence for functional interaction between replication origin distribution and two subunits of the Smc5/6 complex, Smc6 and Mms21, as well as Top1. An artificial chromosome that has a long arm having low origin density (5ori∆YAC) is relatively unstable compared to the YAC having normal origin distribution in wild-type cells, but is partially stabilized in smc6-56 and top1∆ mutants...

Persistent B cell responses in mucosal tissues are crucial to control infection against sexually transmitted pathogens like human immunodeficiency virus 1 (HIV-1). The genital tract is a major site of infection by HIV. Sublingual (SL) immunization in mice was previously shown to generate HIV-specific B cell immunity that disseminates to the genital tract. We report here the immunogenicity in female cynomolgus macaques of a SL vaccine based on a modified gp41 polypeptide coupled to the cholera toxin B subunit designed to expose hidden epitopes and to improve mucosal retention...

Firmness, one of the major determinants of postharvest quality and shelf life of fruits is determined by the mechanical resistance imposed by the plant cell wall. Expansins (EXP) are involved in the non-hydrolytic metabolic disassembly of plant cell walls, particularly in processes where relaxation of the wall is necessary, such as fruit development and ripening. As many carbohydrate-associated proteins, expansins have a putative catalytic domain and a carbohydrate-binding module (CBM). Several strategies have been pursued to control the loss of fruit firmness during storage...

Changes in range of motion affect the magnitude of the load during the squat exercise and, consequently may influence muscle activation. The purpose of this study was to evaluate muscle activation between the partial and full back squat exercise with external load equated on a relative basis between conditions. Fifteen young, healthy, resistance trained men (age: 26±5 years, height: 173±6 cm) performed a back squat at their 10 repetition maximum using two different ranges of motion (partial and full) in a randomized, counterbalanced fashion...
