Diapause is a physiological adaptation that allows an organism to survive adverse environmental conditions. Diapause occurs at a specific developmental stage in each species. There are few reports regarding the molecular regulatory mechanism of nymphal diapause in Laodelphax striatellus, which is an important graminaceous crop pest. Our previous studies identified the conditions for nymphal diapause in this species. Here, we combined RNA sequencing transcriptomics and quantitative proteomic analyses to identify nymphal diapause-related genes and proteins...

PURPOSE: To determine if jumping performance changes during a peaking phase differed between returners and new players in a female collegiate volleyball team and to determine which variables best explained the variation in performance changes. METHODS: Fourteen volleyball players were divided into two groups: returners (n=7) and new players (n=7) who completed a 5-week peaking phase prior to conference championships. Players were tested at baseline prior to the pre-season on measures of vastus lateralis cross-sectional area using ultrasonography, estimated back squat one repetition maximum (1-RM), and countermovement jump height (JH) and relative peak power (PPa) on a force platform...

Hydrogen bonds involving the backbone phosphate groups occur with high frequency in functional RNA molecules. They are often found in well-characterized tertiary structural motifs presenting powerful probes for the rapid identification of these motifs for structure elucidation purposes. We have shown recently that stable hydrogen bonds to the phosphate backbone can in principle be detected by relatively simple NMR-experiments, providing the identity of both the donor hydrogen and the acceptor phosphorous within the same experiment (Duchardt-Ferner et al...

Insulin-like peptides (ILPs) sense and transduce nutritional information and are linked to female reproduction in many insect species. Our previous studies have shown that "Target of rapamycin" (TOR) pathway functions through juvenile hormone (JH) to regulate amino acids-mediated vitellogenesis in the brown planthopper, Nilaparvata lugens, one of the most destructive rice pests in Asia. Recent reports have demonstrated that DNA methyltransferases (Dnmts) are also involved in female reproduction of N. lugens...

Juvenile hormone (JH) plays important roles in insect development and physiology. JH titer is tightly regulated to coordinately adjust systemic physiology and development. Although control of JH titer is explained by the expression of JH biosynthetic enzymes in the corpora allata (CA), molecular mechanisms that regulate the expression of these genes remain elusive. In the present study, to identify novel regulators of JH biosynthetic genes, we conducted a gene expression screen using the CA and corpora cardiaca (CC) of the silkworm, Bombyx mori, in the JH synthesis period...

The innate immune response shapes the development of adaptive immunity following infections and vaccination. However, it can also induce symptoms such as fever and myalgia, leading to the possibility that the molecular basis of immunogenicity and reactogenicity of vaccination are inseparably linked. To test this possibility, we used the yellow fever live-attenuated vaccine (YFLAV) as a model to study the molecular correlates of reactogenicity or adverse events (AEs). We analyzed the outcome of 68 adults who completed a YFLAV clinical trial, of which 43 (63...

Insulator-based dielectrophoresis (iDEP) is known as a powerful technique for separation and manipulation of bioparticles. In recent years, iDEP designs using arrays of insulating posts have shown promising results towards reaching high-efficiency bioparticle manipulation. Joule heating (JH) and electrothermal (ET) flows have been observed in iDEP microdevices and significantly affecting their performances. In this research, we utilize mathematical modeling to study, in detail, iDEP technique and the effects of JH and ET flow on device performance and propose our separation scenario for selective trapping of circulating tumor cells (CTCs)...

Many hybridoma researchers have lost an important hybridoma because of instability, mechanical breakdown of a freezer, or contamination. In many cases, however, it is possible to retrieve the heavy- and light-chain sequences from those hybridomas. Although most cloning methods associated with isolation of VH or VL gene sequences require the isolation of intact, nondegraded mRNA, alternative approaches based on genomic DNA have been reported. With genomic DNA, the DNA sample can remain relatively intact in cases in which the mRNA has been degraded...

Arterial stiffness, a marker for cardiovascular risk, is increased in patients with Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA). The specific influence of both on arterial stiffness during sleep is unknown. Nocturnal arterial stiffness (Pulse Propagation Time (PPT) of the finger pulse wave) was calculated in 142 individuals evaluated for sleep apnea: 27 COPD patients (64.7 ± 11y, 31.2 ± 8 kg/m(2)), 72 patients with cardiovascular disease (CVD group, 58.7 ± 13y, 33.6 ± 6 kg/m(2)) and 43 healthy controls (HC group 49...

The PI3K-AKT signalling cascade has a highly conserved role in a variety of processes including cell growth and glucose homoeostasis. Variants affecting this pathway can lead to one of several segmental overgrowth disorders. These conditions are genetically heterogeneous and require tailored, multidisciplinary involvement throughout life. Hypoglycaemia is common in other overgrowth syndromes but has been described only sporadically in association with PIK3CA and CCND2 variants. We report a cohort of 6 children with megalencephaly-capillary malformation syndrome (MCAP) and megalencephaly-polydactyly-polymicrogyria-hydrocephalus syndrome (MPPH) who developed clinically significant hypoglycaemia...

BACKGROUND: Elderly patients with somatic symptom disorder (SSD) put a great burden on the health care delivery system. Cognitive behavioral therapy (CBT) is effective in adults with SSD. However, no studies have been conducted yet into CBT for SSD in later life. OBJECTIVES: We explored the feasibility of CBT for SSD in the elderly. METHODS: This is a prospective pilot study comparing two outpatient specialty mental health settings for adults (<60 years; n=13) and for elderly patients (≥60 years; n=9) with SSD...

Formation and expression of memories are critical for context-dependent decision making. In Drosophila, a courting male rejected by a mated female subsequently courts less avidly when paired with a virgin female, a behavioral modification attributed to "courtship memory." Here we show the critical role of hormonal state for maintenance of courtship memory. Ecdysis-triggering hormone (ETH) is essential for courtship memory through regulation of juvenile hormone (JH) levels in adult males. Reduction of JH levels via silencing of ETH signaling genes impairs short-term courtship memory, a phenotype rescuable by the JH analog methoprene...

Hormones play essential roles during development and maintaining homeostasis in adult organisms, regulating a plethora of biological processes. Generally, hormones are secreted by glands and perform a systemic action. Here we show that Juvenile Hormones (JHs), insect sesquiterpenoids synthesized by the corpora allata, are also synthesized by the adult Drosophila gut. This local, gut specific JH activity, is synthesized by and acts on the intestinal stem cell and enteroblast populations, regulating their survival and cellular growth through the JH receptors Gce/Met and the coactivator Tai...

BACKGROUND & AIMS: Chronic gastrointestinal inflammation increases the risk of cancer by mechanisms that are not well understood. Indoleamine-2,3-dioxygenase 1 (IDO1) is a heme-binding enzyme that regulates the immune response via catabolization and regulation of tryptophan availability for immune cell uptake. IDO1 expression is increased during the transition from chronic inflammation to gastric metaplasia. We investigated whether IDO1 contributes to the inflammatory response that mediates loss of parietal cells leading to metaplasia...

The BIOMED-2 PCR protocol for targeting the IGH gene is widely employed for detecting clonality in B-cell malignancies. Unfortunately, the detection of clonality with this method is not very sensitive when paraffin sections are used as a DNA source. To increase the sensitivity, we devised a semi-nested modification of a JH consensus primer. The clonality detection rates of three assays were compared: the standard BIOMED-2, BIOMED-2 assay followed by BIOMED-2 re-amplification, and BIOMED-2 assay followed by semi-nested BIOMED-2...

The rice brown planthopper, Nilaparvata lugens, is an important migratory pest in many rice planting areas of Asia. The typical wing dimorphism of N. lugens gives them flexibility to adapt to different environmental cues. As an important hormone in the insect's endocrine regulation, juvenile hormone (JH) has previously been shown to participate in the wing morph determination of N. lugens. In this paper, we investigated the possible wing morph determination roles of two JH metabolic enzymes, JH esterase (JHE) and JH epoxide hydrolase (JHEH)...

Eusocial insect colonies are defined by extreme variation in reproductive activity among castes, but the ancestral conditions from which this variation arose are unknown. Investigating the factors that contribute to variation in reproductive physiology among solitary insects that are closely related to social species can help to fill this gap. We experimentally tested the role of nutrition, juvenile hormone (JH) and social cues on reproductive maturation in solitary alkali bees (Halictidae: Nomia melanderi)...
