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.

A Critical Review of the Literature on Structural Adjustment and the Environment

open access: yes, 2003
This paper analyzes the available literature about the effects of structural adjustment programs (SAPs) on the environment and the convincing evidence for their success or failure.

Associations of heart rates and respiratory rates with lifestyle and environmental factors in toddlers: a nationwide cohort study

open access: yesBMC Pediatrics
Background Heart rate (HR) and respiratory rate (RR) are key vital signs, yet few large studies have reported their normal values in toddlers. We thus assessed HR and RR in two-year-old Japanese children.

Environmental enrichment, age and PPARα interact to regulate proliferation in neurogenic niches

open access: yesFrontiers in Neuroscience, 2016
Peroxisome proliferator-activated receptor alpha (PPARα) ligands have been shown to modulate recovery after brain insults such as ischemia and irradiation by enhancing neurogenesis. In the present study, we investigated the effect of the genetic deletion

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

open access: yesFEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Desert dermatoses (Thar desert, India)

open access: yesIndian Journal of Dermatology, 2017
Desert dermatology describes the cutaneous changes and the diseases affecting those living in the desert. Diurnal variation in temperature is high and is characteristic of the deserts. The lack of water affects daily activities and impacts dermatological

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Sustentabilidad ambiental y contradicciones sociales Environmental sustainability and social contradictions

open access: yesAmbiente & Sociedade, 1999
Neste artigo analisamos as definições e medições de sustentabilidade. Mostramos que enquanto as definições incluem um elemento inter-geração e um outro de equidade intra-geração, a maioria das medições somente recuperam o primeiro elemento. Explicamos as

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 ...
