Antioxidant Defenses in the Kidneys and Heart of the Freshwater Fish Astyanax lacustris Subjected to High (31°C) and Low (15°C) Temperatures. [PDF]

Cell Biochem Funct
ABSTRACT Aquatic ecosystems have their abiotic and biotic factors constantly altered by various factors. Among them, water temperature is an abiotic factor that can significantly affect fish physiology, increasing energy demand, which can impact homeostasis and survival. Endocrine and metabolic changes and enzymatic modulation are referred to as stress

Novel Helical Trp‐ and Arg‐Rich Antimicrobial Peptides Locate Near Membrane Surfaces and Rigidify Lipid Model Membranes

Advanced NanoBiomed Research, Volume 3, Issue 5, May 2023., 2023
To provide alternatives to traditional antibiotics, six rationally designed antimicrobial peptides (AMPs) are studied. Circular dichroism (CD) measurements reveal that increased helicity correlates with increased efficacy (lower minimum inhibitory concentrations [MICs]) in G(–) and G(+) lipid model membranes (LMMs). X‐ray diffuse scattering (XDS) shows

Noncanonical metabolite RNA caps: Classification, quantification, (de)capping, and function

WIREs RNA, Volume 13, Issue 6, November/December 2022., 2022
Metabolite caps are distinct 5′‐terminal modifications of RNA that occur in prokaryotes and eukaryotes. Abundant metabolites such as NAD, CoA, or NpnNs serve as noncanonical initiating nucleotides during transcription. Turnover, stability, and function are tightly regulated for specific subgroups of metabolite‐capped RNAs.

A comprehensive coverage insurance for cells: revealing links between ribosome collisions, stress responses and mRNA surveillance [PDF]

, 2022
Cells of metazoans respond to internal and external stressors by activating stress response pathways that aim for re-establishing cellular homoeostasis or, if this cannot be achieved, triggering programmed cell death. Problems during translation, arising

Progressive Transient Photon Beams [PDF]

, 2018
In this work we introduce a novel algorithm for transient rendering in participating media. Our method is consistent, robust, and is able to generate animations of time-resolved light transport featuring complex caustic light paths in media.

Zinc finger proteins of Plasmodium falciparum

Cellular Microbiology, Volume 23, Issue 12, December 2021., 2021
Schematic of a C2H2‐type zinc finger motif comprising a two‐stranded antiparallel β‐sheet and an α‐helix coordinated by a zinc ion. The zinc ion is depicted by a Plasmodium falciparum ring stage. In the ring stages, C2H2‐type zinc finger proteins are mainly involved in cell cycle regulation and mRNA metabolism.

Massively parallel cis-regulatory analysis in the mammalian central nervous system [PDF]

, 2015
Cis-regulatory elements (CREs, e.g., promoters and enhancers) regulate gene expression, and variants within CREs can modulate disease risk. Next-generation sequencing has enabled the rapid generation of genomic data that predict the locations of CREs ...

Dopamine receptors in GtoPdb v.2023.1 [PDF]

, 2023
Dopamine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Dopamine Receptors [373]) are commonly divided into D1-like (D1 and D5) and D2-like (D2, D3 and D4) families, where the endogenous agonist is ...
