Regional Prediction of Soil Nutrient Availability and Management Using Portable X‐Ray Fluorescence Spectrometry

X-Ray Spectrometry, EarlyView.
ABSTRACT Portable x‐ray fluorescence (pXRF) spectroscopy has emerged as a rapid and cost‐effective technique for soil elemental analysis; however, its application for predicting available nutrients and supporting agronomic decision making remains insufficiently evaluated under field conditions.

Impact of Chelators on FAC Following Interaction With NaOCl: A Focused Evidence Synthesis Based on a Systematic Search

Australian Endodontic Journal, EarlyView.
ABSTRACT This systematic review following PRISMA guidelines evaluated the effects of endodontic chelators on free available chlorine (FAC) in sodium hypochlorite (NaOCl), with emphasis on the influence of concentration, contact time, temperature, and pH. Risk of bias was assessed using the Quality Assessment Tool for In Vitro Studies (QUIN).

Effect of Lime, Humic Acid and Moisture Regime on the Availability of Zinc in Alfisol

The Scientific World Journal, 2007
Lime and humic acid application can play an important role in the availability of zinc in paddy soils. We conducted laboratory incubation experiments on a rice growing soil (Alfisol) to determine the effect of lime, humic acid and different moisture ...

Cisterna Chyli Dilation Is a Risk Factor for Liver Nodules and Hepatocellular Carcinoma in Fontan‐Associated Liver Disease: Pathophysiological Role of Lymphatic Dysfunction

Hepatology Research, EarlyView.
ABSTRACT Aim In Fontan‐associated liver disease (FALD), chronic congestion often confounds conventional fibrosis markers, complicating surveillance for hepatocellular carcinoma (HCC). Although lymphatic dysfunction is fundamental to Fontan physiology, its contribution to hepatocarcinogenesis remains unclear.

Regulation by the Transcriptional Regulator YdcI in E. coli and (p)ppGpp‐Dependent Activation of ydcI Expression

Molecular Microbiology, EarlyView.
YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

Peptide transporter DtpA has two alternate conformations, one of which is promoted by inhibitor binding

, 2013
Peptide transporters (PTRs) of the large PTR family facilitate the uptake of di- and tripeptides to provide cells with amino acids for protein synthesis and for metabolic intermediates.
