Higher neutrophil count, higher lymphocyte-to-monocyte ratio, and lower platelet-to-lymphocyte ratio are independently associated with postpartum depression symptoms in twin pregnancies

Frontiers in Immunology
IntroductionPostpartum depression (PPD) is a common complication with adverse maternal and child outcomes. Immune−inflammatory dysregulation has been implicated in its pathogenesis, but evidence from twin pregnancies is limited.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Cast Microstructure and Crystallographic Features of Al₃Sc Dendrites in High Sc-Contained Al-Sc Alloys

Crystals
Al-Sc alloys containing high Sc content are employed as sputtering targets for the fabrication of high-performance piezoelectric films during magnetic sputtering. Due to the high proportion of the Al3Sc phase, their workability is quite limited, and they

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Extra-uterine twin pregnancy: case report of spontaneous bilateral tubal ectopic pregnancy

The Pan African Medical Journal, 2015
Spontaneous bilateral ectopic pregnancy is the rarest form of ectopic pregnancy. Bilateral tubal pregnancies in the absence of preceding induction of ovulation are a rare occurrence, with an estimated incidence of 1 in 725 to 1 in 1580 ectopicpregnancies.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Paternal age and the risk of cerebral palsy

Anthropological Review, 2020
In the literature there are no unequivocal assessments of the effect of paternal age on the risk of cerebral palsy (CP). The objective of the studies was the analysis of the influence of paternal age on this risk, considering all the important risk ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

FEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
