Sleep Deprivation Activates a Conserved Lactate‐H3K18la‐RORα Axis Driving Neutrophilic Inflammation Across Species

Advanced Science, EarlyView.
Sleep deprivation triggers systemic immune activation characterized by neutrophil accumulation and cytokine release. This study reveals a conserved metabolic‒epigenetic mechanism whereby lactate‐induced H3K18 lactylation upregulates RORα expression, promoting neutrophilic inflammation.

Fecundación in vitro : millorant la crioconservació [PDF]

, 2008
En el camp de la fecundació in vitro es poden utilitzar oòcits frescos o crioconservats (congelats). Els avantatges de la crioconservació són evidents, però té un desavantatge important : l'eficàcia de la fecundació és molt menor.

Post-copulatory opportunities for sperm competition and cryptic female choice provide no offspring fitness benefits in externally fertilizing salmon [PDF]

, 2016
There is increasing evidence that females can somehow improve their offspring fitness by mating with multiple males, but we understand little about the exact stage(s) at which such benefits are gained.

Long-term GnRH agonist therapy before in vitro fertilisation (IVF) for improving fertility outcomes in women with endometriosis.

Cochrane Database of Systematic Reviews, 2019
BACKGROUND Endometriosis is known to have an impact on fertility and it is common for women affected by endometriosis to require fertility treatments, including in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI), to improve the ...

Implantable Ion‐Selective Organic Electrochemical Transistors Enable Continuous, Long‐Term, and In Vivo Plant Monitoring

Advanced Science, EarlyView.
This work explores ion‐selective organic electrochemical transistors for real‐time, long‐term potassium monitoring in the xylem sap of living trees. This bioelectronic approach provides new insights into plant physiology and has the potential to revolutionize forest, agricultural, and ecological monitoring for smarter, more sustainable plant management.

Gene expression analysis of bovine embryonic disc, trophoblast and parietal hypoblast at the start of gastrulation [PDF]

, 2017
In cattle early gastrulation-stage embryos (Stage 5), four tissues can be discerned: (i) the top layer of the embryonic disc consisting of embryonic ectoderm (EmE); (ii) the bottom layer of the disc consisting of mesoderm, endoderm and visceral hypoblast

PCSK9 Loss‐of‐Function Disrupts Cellular Microfilament Network via LIN28A/HES5/JMY Axis in Neural Tube Defects

Advanced Science, EarlyView.
PCSK9 acts as a molecular chaperone promoting LIN28A lysosomal degradation. LIN28A elevates transcription factor HES5, increasing JMY expression. PCSK9 loss causes neural tube defects (NTDs) by disrupting the LIN28A/HES5/JMY axis, and high JMY disorganizes the neural progenitor cell microfilament network, leading to incomplete neural tube structure in ...

Should We Be Offering Intracytoplasmic Sperm Injection to All Couples with Unexplained Infertility: A Cohort Study

Journal of Human Reproductive Sciences
Background: In unexplained infertility (UI), the use of intracytoplasmic sperm injection (ICSI) has been increased to prevent total fertilisation failure (TFF). However, there is little evidence to support improved clinical outcomes.
