Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Preparation and evaluation of microspheres with dual polymeric film to minimize burst effect of highly water soluble drug

open access: yesJournal of Contemporary Pharmacy, 2021
Double-layered controlled release microspheres of venlafaxine were prepared using ethyl cellulose (EC) as a wall forming hydrophobic polymer. Usually, it is difficult to control initial sudden release of highly water-soluble drugs.

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

open access: yesFEBS 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 ...

Jus in bello a operace Irácká svoboda

open access: yesObrana a strategie, 2010
War is a constant feature of human affairs and a permanent topic of ethical debates. Moral reasoning about war and peace known as just war theory has its roots in Christian ethics and is connected to positive international law.

Nonresponse Effect in Double Sampling: A Simulation Study [PDF]

open access: yesThe Egyptian Statistical Journal, 1995
We consider estimation of the population total in double sampling for regression in the presence of nonresponse. Two estimators were examined, one allowing for nonresponse and the other based only on respondents'set.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS 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

Evolution of correlated electrons in La3Ni2O7 at ambient pressure: a study of double-counting effect

open access: yesAAPPS Bulletin
We employ cluster extension of dynamical mean-field theory (CDMFT) to systematically investigate the impact of double counting corrections on the correlated electronic structure of La3Ni2O7 under ambient pressure. By adjusting double-counting parameters,
