Fluctuations of the Empirical Measure of Freezing Markov Chains [PDF]

open access: yes, 2017
In this work, we consider a finite-state inhomogeneous-time Markov chain whose probabilities of transition from one state to another tend to decrease over time. This can be seen as a cooling of the dynamics of an underlying Markov chain.

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+.

Effect of Centrifugation on Motility, Sperm Capacitation and Acrosome Reaction in Soy Bean and Avocado Seed Milk Extenders of Cryopreserved Goat Spermatozoa

open access: yesAgricultura Tropica et Subtropica, 2017
Removal of seminal plasma by centrifugation (0 centrifugation, 1 centrifugation, 2 centrifugations, 3 centrifugations) and preservation in two different tris-extenders viz., avocado seed milk (ASM) and soy bean milk (SBM) based extenders were studied for

Comparison of Varying Tissue Freezing Methods on Murine Colonic Tissue [PDF]

open access: yes, 2018
Histology often requires a tissue specimen to be embedded so that it may be sectioned, stained, and mounted on a microscope slide for viewing. One common method of tissue embedding for rapid histology is freezing, since freezing allows tissue to be ...

Lattice model study of the thermodynamic interplay of polymer crystallization and liquid-liquid demixing

open access: yes, 2003
We report Monte Carlo simulations of a lattice-polymer model that can account for both polymer crystallization and liquid-liquid demixing in solutions of semiflexible homopolymers.

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.

Combined Effects of Different Freezing and Thawing Rates on Meat Quality Characteristics of Aged Lamb Loins

open access: yesMeat and Muscle Biology
The objective of this study was to determine the combined effects of different freezing and thawing rates on the quality characteristics of aged lamb loins. A total of 105 lamb loins at 1 d postmortem were vacuum-packaged and aged for 2w kat −1.5°C.

Some biological aspects of the weed Lesser celandine (Ranunculus ficaria) [PDF]

open access: yesPlanta Daninha, 2013
Lesser celandine (Ranunculaceae) is a perennial weed with tuberous root. Tubers are the most important means of reproduction and dispersion of this weed. In recent years, it has spread into wheat fields in Western Iran, mainly in the Lorestan province. A

Restartable heat pipe [PDF]

open access: yes, 1972
Inclusion in heat pipe of auxiliary working fluid which has considerably lower freezing point than main working fluid enables easy starting after main working fluid has been cooled to or below freezing ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
