Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

A dimeric inhibitor of insect a-amylase from barley. Cloning of the cDNA and identification of the protein [PDF]

open access: yes, 1988
A cDNA clone, designated pUP-44, whose longest open reading frame codes for a protein that is homologous to the wheat α-amylase inhibitors, has been isolated from a library obtained from developing barley endosperm.

Impact of Raw Materials and Drying Temperatures on In Vitro Starch Digestibility of Durum Wheat Pasta

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives The starch digestibility of pasta is influenced by both formulation and processing conditions. However, the effect of increasing drying temperature on the nutritional properties—particularly slowly digestible starch (SDS)—remains controversial.

Cytologic Findings in Esophageal Perforation: An Institutional Experience With Pleural Fluid Specimens

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Introduction Esophageal perforation (EP) is a rare but life‐threatening condition, and most cases are due to iatrogenic causes. The rest occur spontaneously, due to malignancies, or trauma. The mortality rates can approach 50%, and delayed diagnosis of EP exacerbates patient outcomes.

Effect of Metal Ions, Chelating Agent and SH-Reagents on Radish (Raphanus sativus L.) Root β-Amylase [PDF]

open access: yes, 2012
Metal ions play vital roles in enzymes. They may also show sensitivity to various sulfhydryl reagents and chelating reagents. Effect of some metal ions, EDTA and sulfhydryl reagents on the activity of partially purified β-amylase of radish root were ...

Substrate induction and glucose repression of maltose utilization by Streptomyces coelicolor A3(2) is controlled by malR, a member of the lacI-galR family of regulatory genes [PDF]

open access: yes, 1997
malR of Strepomyces coelicolor A3(2) encodes a homologue of the Lacl/Galr family of repressor proteins, and is divergently transcribed from the malEFG gene cluster, which encodes components of an ATP-dependent transport system that is required for ...

Covalent Immobilization of Laccase on Mesoporous Bismuth Silicate for High‐Performance Biodegradation of Contaminants

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Myceliophthora thermophila laccase covalently immobilized on bismuth silicate (BiSi‐ext) achieved synergistic adsorption–biodegradation of Tectilon Blue 4R‐01 and ibuprofen. The biocatalyst showed enhanced stability, reusability, and rapid pollutant removal via expanded active‐site accessibility, enabling efficient, eco‐friendly wastewater remediation.
