Endogenous Tissue Inhibitor of Metalloproteinase-2 Levels Are Associated With High-Quality Neat Semen but Unrelated to Sperm Cryoresistance in Bulls.

Tissue Inhibitor of Metalloproteinase-2 (TIMP-2) is part of the tissue inhibitors of the metalloproteinases (TIMPs) family. Its primary function is to regulate the activity of matrix metalloproteinases (MMPs) across various tissues, including those of the reproductive system. This study aimed to quantify the natural levels of TIMP-2 in seminal plasma (SP) and sperm membrane (SM) of bulls, explore potential associations between TIMP-2 levels and semen quality parameters, and examine the relationship between TIMP-2 levels and sperm cryoresistance in bulls.

Penalized estimation in parametric frailty model.

Frailty model examines the effect of observable and non-observable factors on time to event data. Presence of collinearity produces unstable estimates of parameters. Therefore, this research focus on the penalized estimation of frailty model and proposed the new estimator which is the extension of ridge and principal component estimators.

CRISPR/Cas9-induced knockout of an amino acid permease gene (AAP6) reduced Arabidopsis thaliana susceptibility to Meloidogyne incognita.

Background: Plant-parasitic root-knot nematode (Meloidogyne incognita) causes global yield loss in agri- and horticultural crops. Nematode management options rely on chemical method. However, only a handful of nematicides are commercially available.

Estimation of Ultrasonic Velocity, Density, Internal Pressure, and Thermophysical Parameters of Ionic Liquid Mixtures: Application of Flory's Statistical Theory.

Flory's statistical theory (FST) has been employed to estimate the ultrasonic velocity, density, internal pressure, and several important thermophysical parameters such as the energy of vaporization, the heat of vaporization, cohesive energy density, polarity index, and solubility for eight binary mixtures of ionic liquids and water within the temperature range of 288.15 to 308.15 K.

A Draft Transcriptome Announcement of .

, the wheat seed gall nematode, causes the 'ear-cockle' or seed gall disease of wheat (), leading to an extensive decline of yield (30-70%) in underdeveloped wheat cultivating countries of the world. The nematode is known to survive in anhydrobiotic conditions for up to 32 years. Here, we present the first transcriptome assembly of , which will be a valuable resource for understanding the genes responsible for nematode survival and above-ground plant parasitism.
