OXYGEN CONSUMPTION BY BOTTOM SEDIMENT

Doboku Gakkai Ronbunshu, 1992
流速の変動する感潮部において堆積した底泥による酸素消費を, 定量的かつ一般的に評価する方法について検討した. 浮遊させた底泥による酸素消費特性について検討した後, その結果を用いて, 河床に堆積した底泥による酸素消費を, 浮遊時の酸素消費特性, 堆積状態, 底泥上の流水の特性により評価する方法を, 実験とモデルにより考察した.

Protocol for quantifying miRNA trafficking across the endosomal membrane

FEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Survival of Escherichia coli in lake bottom sediment [PDF]

Applied and Environmental Microbiology, 1982
The survival of Escherichia coli in bottom sediment (Lake Onalaska, navigation pool no. 7, Mississippi River) was studied by using in situ dialysis culture of sterile (autoclaved) and unsterile sediment samples. Bags made from dialysis tubing were filled with either course sand sediment (28.8% fine) or organic, silty clay sediment (77.2% fine) and ...

Heterotropic regulation and negative homotropic cooperativity

FEBS Open Bio, EarlyView.
We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Chemical and environmental assessment of the bottom sediments in the Irtysh River (Tyumen Region, Russian Federation)

Vestnik MGTU, 2019
The total concentration of Al, Co, Fe, Mn, Pb, Cu, Zn, Sr, As, Cr, Ni has been determined in the test portions of the bottom sediments (sand, loamy sand, sandy loam, silt and clay loam) in the lower reach of the Irtysh River. Atomic emission spectroscopy

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

Impact of Plasma p‐tau181 on Cognition, Motor Phenotypes, and Disease Course in ALS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Phosphorylated tau181 (p‐tau181), an Alzheimer's disease biomarker, was recently evaluated in amyotrophic lateral sclerosis (ALS). We investigated plasma p‐tau181 in 202 ALS/ALS‐FTD patients and 94 healthy controls, assessing cognitive performance, motor function, and longitudinal dynamics.

SPECIAL FEATURES OF THE TECHNOGENIC BOTTOM SEDIMENTS IMPACT ON THE WATER BODIES MERCURY POLLUTION CHARACTER

Водное хозяйство России: проблемы, технологии, управление, 2020
The article studies the impact of mercury-containing bottom sediments on the pollution of the surface water body – the Elkhovka River, which for a long time was affected by the enterprises of the Kirovo-Chepetsk industrial hub, to assess the possibility

T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±
