Dynamic responses during early development of the sea urchin Strongylocentrotus intermedius to CO-driven ocean acidification: A microRNA-mRNA integrated analysis.

Key Laboratory of Mariculture & Stock Enhancement in North China's Sea, Ministry of Agriculture and Rural Affairs, Dalian Ocean University, Dalian, Liaoning 116023, PR China. Electronic address:
To explore the dynamic molecular responses to CO-driven ocean acidification (OA) during the early developmental stages of sea urchins, gametes of Strongylocentrotus intermedius were fertilized and developed to the four-armed larva stage in either natural seawater (as a control; pH = 7.99 ± 0.01) or acidified conditions (ΔpH = -0.

Research Question: To what extent do legislative measures impact standard reproductive outcome parameters?
Design: Retrospective cohort study using data from the Swiss national IVF registry analysing the outcomes of 13,908 women undergoing embryo transfers resulting from their first lifetime oocyte retrieval before (2014-2016) or after (2020-2022) revision of the legislation, allowing extended culture for 12 zygotes. Live birth rates (LBR) and cumulative LBR (cLBR) were compared in fresh and frozen embryo transfer strategies in both periods. Adjusted multivariable mixed model analyses were performed to determine OR and incidence rate ratios (IRR).
Small RNA sequencing analysis provides novel insights into microRNA-mediated regulation of defense responses in chickpea against Fusarium wilt infection.

ICAR-National Institute for Plant Biotechnology, New Delhi, 110012, Delhi, India.
Small RNA sequencing analysis in two chickpea genotypes, JG 62 (Fusarium wilt-susceptible) and WR 315 (Fusarium wilt-resistant), under Fusarium wilt stress led to identification of 544 miRNAs which included 406 known and 138 novel miRNAs. A total of 115 miRNAs showed differential expression in both the genotypes across different combinations. A miRNA, Car-miR398 targeted copper chaperone for superoxide dismutase (CCS) that, in turn, regulated superoxide dismutase (SOD) activity during chickpea-Foc interaction.

Background: Glycosylation is the most common post-translational modification in the brain. Aberrant glycosylation patterns are present in cerebrospinal fluid and brain tissue from Alzheimer's disease (AD) patients. Specifically, dysregulation of a particular form of terminal glycoconjugate modification, sialylation, has been identified in AD.

Background: Alzheimer's disease (AD) features stereotypical spread of hyperphosphorylated tau (p-tau) and beta-amyloid. Although other pathological tau posttranslational modifications (PTMs) have been described in AD, a prevalent disease model preconizes that other tau PTMs always coincide with p-tau, making the latter an excellent marker of pathological tau burden. We showed in experimental studies that truncated tau (tr-tau), a pathological tau PTM generated via cleavage by active caspases, is as common as p-tau in neurons at late AD stages; however, only about 40% of tr-tau positive neurons also show p-tau positivity.
