Expression Variations of Chloride Ion Channel Related Genes During Diapause Termination in Silkworm, Bombyx mori.

Instant and refrigerated acid soaking are commonly used in cocoon production to prevent or break diapause, and provide developable silkworm eggs for sericulture, while their mechanisms have not been fully understood. This study aims to investigate the mechanisms by which hydrochloric acid (HCl) or dimethyl sulfoxide (DMSO) promotes embryonic development in silkworm Bombyx mori, focusing on the chloride ion (Cl) related gene expression profiles. Our results revealed that the HCl treatment of up to 6 min enhanced hatchability in freshly picked and cold-stored eggs, whereas a slight decrease in hatchability was observed in those treated with DMSO for 40 min.

Contrasting Multi-Source Temporal Knowledge Graphs for Biomedical Hypothesis Generation.

Hypothesis Generation (HG) aims to expedite biomedical researches by generating novel hypotheses from existing scientific literature. Most existing studies focused on modeling static snapshots of the corpus, neglecting the temporal evolution of scientific terms. Despite recent efforts to learn term evolution from Knowledge Bases (KBs) for HG, the temporal information from multi-source KBs is still overlooked, which contains important, up-to-date knowledge.

Generating Biomedical Hypothesis With Spatiotemporal Transformers.

Generating biomedical hypotheses is a difficult task as it requires uncovering the implicit associations between massive scientific terms from a large body of published literature. A recent line of Hypothesis Generation (HG) approaches - temporal graph-based approaches - have shown great success in modeling temporal evolution of term-pair relationships. However, these approaches model the temporal evolution of each term or term-pair with Recurrent Neural Network (RNN) independently, which neglects the rich covariation among all terms or term-pairs while ignoring direct dependencies between any two timesteps in a temporal sequence.

α-Glucosidase inhibitory flavonol glycosides from Cyclocarya paliurus (Batalin) Iljinskaja and their kinetics characteristics.

Seven previously undescribed flavonol glycosides including four rare flavonol glycoside cyclodimers, dicyclopaliosides A-C (1-3) with truxinate type and dicyclopalioside D (4) with truxillate type, as well as three kaempferol glycoside derivatives cyclopaliosides A-C (5-7), were obtained from the leaves of Cyclocarya paliurus. Their structures were elucidated by extensive spectroscopic methods and chemical analyses. All compounds were evaluated for their inhibitory α-glucosidase activities.

Multidisciplinary team approach to the prenatal management of orofacial clefts: a single center cohort study in Taiwan.

Advances in ultrasound fetal diagnostics and treatment have created a dilemma for doctors and parents: choosing whether to continue with a pregnancy as well as choosing between various treatment options. A multidisciplinary approach has been widely accepted in the management of other prenatally diagnosed anomalies and has shown superior results compared to routine care. We present a retrospective cohort of patients prenatally diagnosed with orofacial clefts who were offered consultation by an expert multidisciplinary team, including: a fetal medicine specialist, an obstetrician, a plastic surgeon, and a case managing nurse.

Differentially expressed microRNAs in diapausing versus HCl-treated Bombyx embryos.

Differentially expressed microRNAs were detected to explore the molecular mechanisms of diapause termination. The total small RNA of diapause-destined silkworm eggs and HCl-treated eggs was extracted and then sequenced using HiSeq high-throughput method. 44 novel miRNAs were discovered.

Low-molecular-weight-heparin can benefit women with recurrent pregnancy loss and sole protein S deficiency: a historical control cohort study from Taiwan.

Background: Heritable thrombophilias are assumed important etiologies for recurrent pregnancy loss. Unlike in the Caucasian populations, protein S and protein C deficiencies, instead of Factor V Lieden and Prothrombin mutations, are relatively common in the Han Chinese population. In this study we aimed to investigate the therapeutic effect of low molecular weight heparin upon women with recurrent pregnancy loss and documented protein S deficiency.

Inactivation and mechanisms of chlorine dioxide on Nosema bombycis.

Biological tests demonstrated that the inactivation of Nosema bombycis (N. bombycis) spores by chlorine dioxide (ClO(2)) occurs very fast and is highly sensitive. The lowest effective inactivation dosage and time was 15mg/mL for 30min.
