In the present study, a novel sample preparation method based on magnetic core-mesoporous shell microspheres with C8-modified interior pore walls (C8-Fe3O4@mSiO2) was established for the identification of 20(S)-protopanaxadiol (PPD) metabolites in rat plasma by UPLC-Q-TOF-MS/MS analysis. C8-Fe3O4@mSiO2 allowed selective extraction of PPD metabolites from rat plasma by excluding macromolecules in the plasma owing to size exclusion effect. Five extraction conditions including the amount of C8-Fe3O4@mSiO2 microspheres used, extraction time, elution solvents, elution volume, and elution time were investigated and optimized...

For many donor-conceiving heterosexual parents, the process of deciding whether and what to tell children about their genetic origin is challenging. We hypothesized that incomplete couple agreement about disclosure could be associated with parenting stress. The aim of the study was to investigate (1) parenting stress levels among heterosexual parents of young children following gamete donation and (2) whether parenting stress is related to perceived agreement about disclosure of the donor conception to the children MATERIAL AND METHODS: This study is part of the longitudinal multicenter Swedish Study on Gamete Donation and included a total of 213 heterosexual parents with children age 1-4 years following oocyte donation (n = 103) and sperm donation (n = 110)...

Lekking males aggregate to attract females and contribute solely to egg fertilization, without any further parental care. Evolutionary theory therefore predicts them to be non-choosy towards their mates, because any lost mating opportunities would outweigh the benefits associated with such preferences. Nevertheless, due to time costs, the production of energetically costly sexual displays, and potential sperm limitation, the mating effort of lekking males is often considerable. These factors, combined with the fact that many females of varying quality are likely to visit leks, could favor the evolution of male mate preferences...

A 42-residue polypeptide conjugated to a small organic molecule capable of targeting the phosphorylated side chain of Ser-15 was shown to bind glycogen phosphorylase a (GPa) with a KD of 280 nM. The replacement of hydrophobic amino acids by Ala reduced affinities, whereas the incorporation of L-2-aminooctanoic acid (Aoc) increased affinities. Replacing Nle-5, Ile-9 and Leu-12 by Aoc reduced the KD from 280 nM to 27 nM. Downsizing the 42-mer to an 11-mer gave rise to an order of magnitude lower affinity for GPa but the 11-mer where Nle-5, Ile-9 and Leu-12 were replaced by Aoc showed a KD of 550 nM, comparable to that of the parent 42-mer...

BACKGROUND: Conjugating amino acid and glucose fragments with existed pesticide structures has been proven to be an effective way to introduce phloem mobility to non-phloem mobile species. However, the resulting derivatives always suffered from lower bioactivity compared to their parent compound. To solve this problem, herein, we designed and synthesized a series of ester-capped amino acid conjugated chlorantraniliprole. RESULTS: The systemic test showed that all conjugates exhibited excellent phloem mobility and xylem mobility in a Ricinus communis model...

Dentatorubro-pallidoluysian atrophy (DRPLA) is a spinocerebellar ataxia (SCA) very rare in non-Asian populations. To date, DRPLA was undetected in the general Brazilian population. Adult-onset ataxic patients have been recruited from several Brazilian neurology and neurogenetics centers. CAG lengths at SCA1, SCA2, SCA3/MJD, SCA6, SCA7, SCA12, SCA17 and DRPLA associated genes, and ATTCT expansions at SCA10 gene were studied. A single DRPLA case detected is reported. Proband was a 69-year-old Brazilian woman of mixed ancestry, with a late-onset pure ataxia: her alleles at the associated gene, ATN1, presented 14/52 CAG repeats...

Although difficulty conceiving a child has long been a major medical and social preoccupation, it has not been considered as a predictor of long-term outcomes in children ultimately conceived. This is consistent with a broader gap in knowledge regarding the consequences of parental health for educational performance in offspring. Here we address that omission, asking how resolved parental infertility relates to children's academic achievement. In a sample of all Swedish births between 1988 and 1995, we find that involuntary childlessness prior to either a first or a second birth is associated with lower academic achievement (both test scores and GPA) in children at age 16, even if the period of infertility was prior to a sibling's birth rather than the child's own...

Duck enteritis virus (DEV) UL54 is a homologue of human herpes simplex virus-1 (HSV-1) ICP27, which plays essential regulatory roles during infection. Our previous studies indicated that DEV UL54 is an immediate-early protein that can shuttle between the nucleus and the cytoplasm. In the present study, we found that UL54-deleted DEV (DEV-ΔUL54) exhibits growth kinetics, a plaque size and a viral DNA copy number that are significantly different from those of its parent wild-type virus (DEV-LoxP) and the revertant (DEV-ΔUL54 (Revertant))...

Eczema in children is a chronic disabling condition. The impact of this condition on the lives of families is often underestimated by conventional physicians. As a consequence parents may investigate complementary treatment options. Close monitoring by a paediatrician is essential, considering that a variety of adverse effects can occur during the use of complementary treatment. We present a 5-year-old girl with eczema. She visited a Chinese herbalist who prescribed an ointment. The parents noticed that the eczema resolved fast, itching decreased and she was finally sleeping well...

Neutrophils are the primary immune cells that respond to inflammation and combat microbial transgression. To thrive, the bacteria residing in their mammalian host have to withstand the antibactericidal responses of neutrophils. We report that enterobactin (Ent), a catecholate siderophore expressed by Escherichia coli, inhibited PMA-induced generation of reactive oxygen species (ROS) and neutrophil extracellular traps (NETs) in mouse and human neutrophils. Ent also impaired the degranulation of primary granules and inhibited phagocytosis and bactericidal activity of neutrophils, without affecting their migration and chemotaxis...

Higher fungiform papillae density (FPD) has been associated with lower taste sensitivity thresholds and greater perceived taste intensity along with consumption of fewer fruit and vegetables (FV). Children exposed to greater variety of FV tend to habitually consume more FV, however, it is unknown whether exposure effects are attenuated by individual differences in FPD or whether these effects vary according to sensory properties of FV. This study examined the links between children's FPD, current variety of FV consumed, and past experiences with variety of fruit and vegetables...

Individuals exposed to adverse childhood experiences (ACEs) are vulnerable to various health problems later in life. This study was designed to determine whether participation in an efficacious program to enhance supportive parenting would ameliorate the association between ACEs and prediabetes status at age 25. Rural African American parents and their 11-year-old children (N=390) participated in the Strong African American Families (SAAF) program or a control condition. Each youth at age 25 provided a total ACEs score and a blood sample from which overnight fasting glucose was assayed...

Doxorubicin (DOX) is one of the most commonly used and effective chemotherapeutic agents. Despite its clinical benefits, the use of DOX is often limited by serious adverse effects, such as severe cardiotoxicity and myelosuppression. Recent progress in chemical synthesis has enabled the design of modified anthracyclines with a sugar moiety being a desirable subject of research. A series of new analogues of DOX has been synthesised, in which the amino group in the daunosamine moiety was replaced by a formamidine system containing the rest of the cyclic secondary amine with gradually increased ring size...

Human fertility is dependent upon the correct establishment and differentiation of the germline. This is because no other cell type in the body is capable of passing a genome and epigenome from parent to child. Terminally differentiated germline cells in the adult testis and ovary are called gametes. However, the initial specification of germline cells occurs in the embryo around the time of gastrulation. Most of our knowledge regarding the cell and molecular events that govern human germline specification involves extrapolating scientific principles from model organisms, most notably the mouse...

INTRODUCTION: The pathomechanism of a single subcortical infarct (SSI) may be better determined by assessing the perfusion status between parent artery and ischemic lesion. We aimed to compare the classifications into branch atheromatous disease (BAD) versus non-BAD based on diffusion-weighted imaging (DWI) or computed tomography perfusion (CTP), and to test whether a CTP-based classification improves the predicting power for progression in SSI (PSSI) compared to that by DWI. METHODS: We enrolled 109 consecutive patients with SSI examined by whole-supratentorial brain CTP and follow-up DWI...
