Morphometric Characterization and Condition Factor of Procambarus clarkii (Decapoda: Astacidea: Cambaridae)in Cooling Wells at a Thermoelectric Power Plant in Colombia [PDF]

open access: yesPapéis Avulsos de Zoologia
This study characterized the population dynamics, morphometric traits, and condition status of a red swamp crayfish (Procambarus clarkii) population inhabiting a high-Andean artificial aquatic ecosystem in Colombia.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Relative modulus–relative density relationships in low density polymer–clay nanocomposite foams

open access: yesSoft Matter, 2011
Polymer–clay nanocomposite (PCN) foams represent an important class of new materials in structural engineering, biomedical fields and packaging. This paper reports the relative modulus–relative density relationship, a crucial correlation in cellular solids, for low-density PCN foams. Polyurethane (PU)–natural clay nanocomposite foams with a porosity of

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

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.

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.

RISM clustering algorithm based on relative density and inter-cluster connectivity degree

open access: yesScientific Reports
Clustering complex data structures remains a pivotal challenge in unsupervised learning, particularly when determining the optimal number of clusters in highly non-linear datasets.

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.

Effects of Sand Density and Reinforcement on the Behavior of Buried Tunnel

open access: yesمجلة النهرين للعلوم الهندسية, 2017
This paper aim to study the effects of earth reinforcement on the stresses generated within a semicircular cross-section tunnel lining buried in sandy soil due to surface loading.
