EFFICIENT MONTE CARLO SIMULATION OF BIOLOGICAL AGING [PDF]

open access: yesInternational Journal of Modern Physics C, 1995
A bit-string model of biological life-histories is parallelized, with hundreds of millions of individuals. It gives the desired drastic decay of survival probabilities with increasing age for 32 age intervals.

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.

The influence of substrate, urea supplementation, and liming on the yield and antioxidant activities of Pleurotus sajor-caju M2345 and Pleurotus ostreatus M2191

open access: yesKuwait Journal of Science
Pleurotus species are grown because of their high yield potential, high nutritional and therapeutic value, and ease of growth. This research aimed to evaluate the yield and antioxidant activities of Pleurotus sajor-caju M2345 and Pleurotus ostreatus ...

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.

Human efficiency in detecting and discriminating biological motion

open access: yesJournal of Vision, 2017
Using an "information meter" provided by ideal observer analysis, we measured the efficiency with which human observers processed different walking stimuli against luminance noise and spatial uncertainty to either detect the presence of a walker or to discriminate the walking direction.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Produtividade e eficiência biológica de sistemas pecuários de cria diferindo na idade das novilhas ao primeiro parto e na taxa de natalidade do rebanho no Rio Grande de Sul Productivity and biological efficiency of beef cow-calf systems differing in age at first calving and herd calving rate in Rio Grande do Sul

open access: yesRevista Brasileira de Zootecnia, 2001
Foi avaliada por intermédio da simulação a produtividade e eficiência de sistemas de criação de bovinos de corte no Rio Grande do Sul diferindo na idade das novilhas ao primeiro parto (IP, anos) e na taxa de natalidade (TN): "Sistema Tradicional" (ST) IP=

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 ...

Valorization of Ginkgo biloba Leaf Powder as a Substrate in King Oyster Mushroom (Pleurotus eryngii) Cultivation

open access: yesLife
Ginkgo biloba is widely planted as a colorful foliage tree, and its leaf can be used as a biomass energy source, but it has been underutilized for a long time.

High-efficient synthesis and biological activities of allosamidins

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2014
The pseudo-trisaccharide allosamidin 1 is a potent inhibitor of all family-18 chitinases, and it is confirmed to have insecticidal and antifungal activities. But the synthesis of allosamidins is very difficult, and it is a challengeable subject. Allosamidins were synthesized in solid-liquid phase, total solid-phase and total liquid-phase, respectively.
