An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Cerebrospinal Fluid Proenkephalin Predicts Striatal Atrophy Decades before Clinical Motor Diagnosis in Huntington's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Huntington's disease (HD) is characterized by early, selective, progressive vulnerability of striatal medium spiny neurons (MSNs). Proenkephalin (PENK), a precursor of opioid peptides abundantly expressed in MSNs, is a promising biomarker of striatal integrity, but region‐specific associations and its potential for early‐stage ...

Cerebrospinal Fluid Biomarkers of NLRP3 Pathway, Immune Dysregulation, and Neurodegeneration in Parkinson's Disease: A Meta‐Analysis

open access: yesMovement Disorders, EarlyView.
Abstract Background The activation of the NOD‐, LRR‐ and pyrin domain‐containing protein 3 (NLRP3) inflammasome and associated immune dysregulation is one of the key pathological processes preceding and accompanying α‐synuclein pathology, neuronal damage, and cell death in Parkinson's disease (PD).

Screening of high chitinase-producing stains from Trichoderma harzianum and conditions for enzyme production

open access: yes浙江大学学报. 农业与生命科学版, 2010
Trichoderma harzianum wild-type strains were implanted by N+ to produce mutagenesis. A mutant stain H-13 with higher activity of chitinase was obtained by screening the mutants with transparent zone, and analyzing chitinase activity by DNS method. Single-

Defense heterosis as a novel plant protection strategy: From theory to breeding practice

open access: yesNew Plant Protection, EarlyView.
Defense heterosis, the enhanced disease resistance of hybrids compared to their parents, has evolved from early observations of hybrid vigor to a novel research concept. Advances are now clarifying its diverse genetic and molecular mechanisms across various plant–pathogen interactions.

Chitinases and lung diseases

open access: yesTuberkuloz ve Toraks, 2013
Chitinase enzymes that hydrolize chitin and some articficial substrates are expressed in human despite lacking of the endogenous chitin within the body. Chitinases phatophysiological functions within human are not fully known. Recent evidence revealed that chitinases may have role into some processes of immune responses and inflammatory system. In this
