Mesoscale computational studies of membrane bilayer remodeling by curvature-inducing proteins [PDF]

open access: yesPhysics Reports,543, 1, 1-60, 2014, 2015
Biological membranes constitute boundaries of cells and cell organelles. Physico-chemical mechanisms at the atomic scale are dictated by protein-lipid interaction strength, lipid composition, lipid distribution in the vicinity of the protein, shape and amino acid composition of the protein, and its amino acid contents.

Plasma membrane transport of thyroid hormones and its role in thyroid hormone metabolism and bioavailability.

open access: yesEndocrine reviews, 2001
Although it was originally believed that thyroid hormones enter target cells by passive diffusion, it is now clear that cellular uptake is effected by carrier-mediated processes.

PGC‐1α Activation by Polyphenols: A Pathway to Thermogenesis

open access: yesMolecular Nutrition &Food Research, EarlyView.
Polyphenols, derived from dietary sources such as berries, undergo digestion and interact with gut microbiota, leading to their metabolization in the liver. This process influences bile acid composition, which in turn activates PGC1α, a key regulator of mitochondrial biogenesis and thermogenesis.

Intestinal gluconeogenesis and glucose transport according to body fuel availability in rats [PDF]

open access: yesJ Physiol 566 (15/07/2005) 575-86, 2007
Intestinal hexose absorption and gluconeogenesis have been studied in relation to refeeding after two different fasting phases: a long period of protein sparing during which energy expenditure is derived from lipid oxidation (phase II), and a later phase characterized by a rise in plasma corticosterone triggering protein catabolism (phase III).

Role of STARD4 in sterol transport between the endocytic recycling compartment and the plasma membrane

open access: yesMolecular Biology of the Cell, 2017
The kinetics of sterol transport between the plasma membrane and the endocytic recycling compartment is measured using fluorescence microscopy. STARD4, a small, soluble sterol transport protein, is responsible for 25% of the total transport and 33% of ...

Near‐Infrared Fluorescent Single‐Walled Carbon Nanotubes for Biosensing

open access: yesSmall, EarlyView.
Near‐infrared fluorescent single‐walled carbon nanotubes (SWCNTs) stand out as versatile biosensors due to their spectral overlap with the biological transparency window, surface‐sensitive fluorescence emission, and chemical modularity. This review offers a concise guide to understanding the photophysics of SWCNTs, various functionalization strategies,

Neurotransmitter release: Variations on a theme [PDF]

open access: yes, 1998
Similarities between the ways that synaptic vesicles and large dense-core vesicles release their contents have been emphasized, but recent studies have revealed important mechanistic differences between these two exocytotic ...

Distinct transport vesicles mediate the delivery of plasma membrane proteins to the apical and basolateral domains of MDCK cells

open access: yesJournal of Cell Biology, 1990
Immunoisolation techniques have led to the purification of apical and basolateral transport vesicles that mediate the delivery of proteins from the trans-Golgi network to the two plasma membrane domains of MDCK cells.

Is methamphetamine blood concentration in emergency department patients associated with the clinical picture?

open access: yesAddiction, Volume 120, Issue 5, Page 1007-1015, May 2025.
Abstract Aims This study aimed to describe clinical features and outcomes of patients presenting to the emergency department with analytically confirmed methamphetamine intoxication, to determine the blood concentration of methamphetamine and to test its association with clinical findings.

Understanding the molecular pharmacology of the serotonergic system : using fluoxetine as a model [PDF]

open access: yes, 2011
Objectives: Serotonin is a monoamine neurotransmitter that is widely distributed in the body and plays an important role in a variety of psychological and other body functions such as mood, sexual desire and function, appetite, sleep, memory and learning,
