Cordyceps militaris, a member of Ascomycota, a mushroom referred to as caterpillar Dong-chung-ha-cho, is commercially valuable because of its high content of bioactive substances including cordycepin and its potential for artificial cultivation. Cordycepin (3'-deoxyadenosine) is highly associated with the pharmacological effects of C. militaris. C. militaris is heterothallic in that two mating type loci, idiomorph MAT1-1 and MAT1-2, exist discretely in two different spores. In this study, nine C. militaris strains were mated with each other to prepare new strains that produced a larger amount of cordycepin than the parent strains...

This paper investigates the health effects of the introduction of a near universal paid parental leave (PPL) scheme in Australia, representing a natural social policy experiment. Along with gender equity and workforce engagement, a goal of the scheme (18 weeks leave at the minimum wage rate) was to enhance the health and wellbeing of mothers and babies. Although there is evidence that leave, especially paid leave, can benefit mothers' health post-partum, the potential health benefits of implementing a nationwide scheme have rarely been investigated...

The MS 8.0Wenchuan Earthquake in 2008 caused huge damage to land cover in the northwest of China's Sichuan province. In order to determine the nutrient loss and short term characteristics of change in soil chemical properties, we established an experiment with three treatments ('undestroyed', 'destroyed and treated', and 'destroyed and untreated'), two climate types (semi-arid hot climate and subtropical monsoon climate), and three slope positions (upslope, mid-slope, and bottom-slope) in 2011. Ten soil properties-including pH, organic carbon, total nitrogen, total phosphorus, total potassium, Ca(2+), Mg(2+), alkaline hydrolysable nitrogen, available phosphorus, and available potassium-were measured in surface soil samples in December 2014...

Estimating dispersal - a key parameter for population ecology and management - is notoriously difficult. The use of pedigree assignments, aided by likelihood-based softwares, has become popular to estimate dispersal rate and distance. However, the partial sampling of populations may produce false assignments. Further, it is unknown how the accuracy of assignment is affected by the genealogical relationships of individuals and is reflected by software-derived assignment probabilities. Inspired by a project managing invasive American mink (Neovison vison), we estimated individual dispersal distances using inferred pairwise relationships of culled individuals...

We studied differentiation and gene flow patterns between enantiomorphic door-snail species in two hybrid zones in the Bucegi Mountains (Romania) to investigate the effects of intrinsic barriers (complications in copulation) and extrinsic selection by environmental factors. A mitochondrial gene tree confirmed the historical separation of the examined populations into the dextral Alopia livida and the sinistral Alopia straminicollis in accordance with the morphological classification, but also indicated gene flow between the species...

The heterozygosity status of polymorphic elements of the immune system, such as the Major Histocompatability Complex (MHC), are known to increase the potential to cope with a wider variety of pathogens. Pre- and post-copulatory processes may regulate MHC heterozygosity. In a population where mating occurs among individuals that share identical MHC-haplotypes, post-copulatory selection may disfavour homozygous offspring or ones with two MHC-haplotypes identical to its mother. We tested these ideas by determining the incidence of MHC-heterozygous and MHC-homozygous individuals in a pedigreed, partially consanguineous captive rhesus monkey colony...

Since 2008, Brazil is the largest consumer of agrochemicals, which increases production costs and risks of agricultural products, environment, and farmers' contamination. Sweet pepper, which is one of the main consumed vegetables in the country, is on top of the list of the most sprayed crops. The bacterial spot, caused by Xanthomonas spp, is one of the most damaging diseases of pepper crops. Genetic resistant consists of a suitable way of disease control, but development of durable resistant cultivars as well as understanding of plant-bacterium interaction is being a challenge for plant breeders and pathologists worldwide...

BACKGROUND: Mind-body therapies are often used by people with autism spectrum disorders (ASD). However, there has been little examination into which types of mind-body therapies have been investigated for people with ASD and for what purposes. A systematic review was conducted to evaluate the existing evidence for mind-body therapies for people with ASD, particularly to determine the types of mind-body therapies used and the outcomes that are targeted. METHODS: PubMed, PsychInfo, and Scopus were searched using terms for ASD and mind-body therapies...

Prescription drug misuse is a growing public health concern and has been understudied in Latino populations. The current study tests the relationships between childhood and family characteristics and prescriptions drug misuse among adult Latinos. A subsample of 8,308 Latinos from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were examined. Logistic regression analyses tested associations between parental alcoholism, parental divorce before age 18, and parental death before age 18 and prescription drug misuse and prescription drug use disorder...

Hypoxia plays a critical role during the evolution of malignant cells and tumour microenvironment (TME).Tumour-derived exosomes contain informative microRNAs involved in the interaction of cancer and stromal cells, thus contributing to tissue remodelling of tumour microenvironment. This study aims to clarify how hypoxia affects tumour angiogenesis through exosomes shed from lung cancer cells. Lung cancer cells produce more exosomes under hypoxic conditions than do parental cells under normoxic conditions. miR-23a was significantly upregulated in exosomes from lung cancer under hypoxic conditions...

Taiki Aoshi
Vaccine adjuvants induce innate immune responses and the addition of adjuvants to the vaccine helps to induce protective immunity in the host. Vaccines utilizing live attenuated or killed whole pathogens usually contain endogenous adjuvants, such as bacterial cell wall products and their genomic nucleic acids, which act as pathogen-associated molecular patterns and are sufficient to induce adaptive immune responses. However, purified protein- or antigen-based vaccines, including component or recombinant vaccines, usually lose these endogenous innate immune stimulators, so the addition of an exogenous adjuvant is essential for the success of these vaccine types...

The disposition and metabolism of galunisertib (LY2157299 monohydrate, a TGF-βRI Kinase/ALK5 Inhibitor) was characterized following a single oral dose of 150 mg of [(14)C]-galunisertib (100 µCi) to six healthy human subjects. The galunisertib plasma half-life was 8.6 h, while the (14)C half-life was 10.0 h. Galunisertib was abundant in circulation (40.3% of the (14)C AUC0-24h), with 7 additional metabolites detected in plasma. Two metabolites LSN3199597 (M5, mono-oxidation), and M4 (glucuronide of M3) were the most abundant circulating metabolites (10...

OBJECTIVE: Parental bonding is cited as a determinant of mental health outcomes in childhood, adolescence and early-mid adulthood. Examination of the long-term impact for older adults is limited. We therefore examine the long-term risk of perceived poor parental bonding on mental health across the lifespan and into early-old age. METHODS: Participants (N = 1255) were aged 60-64 years of age and drawn from the Australian Life Histories and Health study. Quality of parental bonding was assessed with the Parental Bonding Instrument (PBI)...

We report the first vibrational circular dichroism (VCD) measurement of spatial heterogeneity in a sample using infrared (IR) microsampling. Vibrational circular dichroism spectra are typically measured using a standard IR cell with an IR beam diameter of 10 mm or greater making it impossible to investigate the spatial heterogeneity of a solid film sample. We have constructed a VCD sampling assembly with either 3 mm or 1 mm spatial resolution. An XY-translation stage was used to measure spectra at different spatial locations producing IR and VCD maps of the sample...

BACKGROUND: Oropharyngeal dysphagia occurs in children without known neurological disorders, increasing their risk for respiratory problems and inadequate intake. Clinicians may recommend thickening nutritive fluids; however, there is little research regarding the impact of thickening nutritive fluids on clinical outcomes in children. METHODS: We used a parental reporting tool to determine whether parents identified changes in signs of dysphagia or volume of intake when thickened fluids were incorporated into an individualized feeding program for dysphagic children without known neurological problems...

A higher competitive advantage of polyploid plants compared with their parental diploids is frequently invoked to explain their establishment success, colonization of novel environments and cytotypic ecological segregation, yet there is scarce experimental evidence supporting such hypotheses. Here, we investigated whether differential competitive ability of species of the Brachypodium distachyon (Poaceae) species complex, a model system for genomic, ecological and evolutionary studies of temperate grasses, contributes to explaining their ecological segregation as well as their coexistence in diploid/allotetraploid contact zones...

Layered 5d transition iridium oxides, Sr2(Ir,Rh)O4, are described as unconventional Mott insulators with strong spin-orbit coupling. The undoped compound, Sr2IrO4, is a nearly ideal two-dimensional pseudospin-1/2 Heisenberg antiferromagnet, similarly to the insulating parent compound of high-temperature superconducting copper oxides. Using polarized neutron diffraction, we here report a hidden magnetic order in pure and doped Sr2(Ir,Rh)O4, distinct from the usual antiferromagnetic pseudospin ordering. We find that time-reversal symmetry is broken while the lattice translation invariance is preserved in the hidden order phase...

BACKGROUND: The liability-threshold model of psychosis risk predicts stronger phenotypic manifestation of the polygenic risk score (PRS) in the healthy relatives of patients, as compared with healthy comparison subjects. METHODS: First-degree relatives of patients with psychotic disorder (871 siblings and 812 parents) and healthy comparison subjects (n = 523) were interviewed three times in 6 years. Repeated measures of two psychosis phenotypes, the Community Assessment of Psychic Experiences (CAPE; self-report - subscales of positive, negative and depressive symptoms) and the Structured Interview for Schizotypy - Revised (SIS-R; clinical interview - subscales of positive and negative schizotypy), were examined for association with PRS...

The aim of this integrative review is to appraise grandparent caregiver interventions that are designed to improve their physical and mental health. A database search was performed to identify relevant studies published between January 1, 1980, and December 31, 2014. Thirteen publications, including 11 studies, met all inclusion and exclusion criteria. All studies included grandparent mental health outcomes with fewer focusing on physical health and social relations. Improvements were found in all three areas with fewer improvements seen in physical health...

There is a constant need for new therapies against multidrug resistant (MDR) cancer. Natural compounds represent a promising class of novel anticancer agents. Recently, we have shown that protoflavones display activity in multidrug resistant cancer cell lines overexpressing the drug efflux pump P-glycoprotein. In the present study, 52 protoflavones, including 22 new derivatives were synthesized and tested against a panel of sensitive parental cells and their MDR derivatives obtained by transfection with the human ABCB1 or ABCG2 genes, or by adaptation to chemotherapeutics...
