Catalytic Autoxidation for Depolymerization of Multilayer Plastic Films

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Catalytic autoxidation using a Co/Mn/Br catalyst system depolymerizes diverse polymers in multilayer plastic films, generating oxygenated small molecules such as dicarboxylic acids. The method tolerates additives and disrupters and converts up to 48 mol% polymer carbon into soluble products, enabling chemical recycling of complex plastic waste ...

Wang-Landau molecular dynamics technique to search for low-energy conformational space of proteins

open access: yes, 2007
Multicanonical molecular dynamics (MD) is a powerful technique for sampling conformations on rugged potential surfaces such as protein. However, it is notoriously difficult to estimate the multicanonical temperature effectively. Wang and Landau developed

Multifactorial Perspective for Greening Solid‐Phase Peptide Synthesis: Rigid Polyacrylate Macroporous Resin in Combination with Green Solvents

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
A rigid, non‐swelling polyacrylate resin enables greener solid‐phase peptide synthesis by allowing various green solvents during the peptide synthesis and significantly reduced process mass intensity without compromising peptide synthesis efficiency/purity.

Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]

open access: yes, 2004
Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential

open access: yesFrontiers in Molecular Neuroscience, 2017
Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.

Effects of Restraint Stress on Circulating Corticosterone and Met Enkephalin in Chickens: Induction of Shifts in Insulin Secretion and Carbohydrate Metabolism

open access: yesAnimals
This study examined the effects of acute restraint stress in the presence or absence of naltrexone on the circulating concentrations of insulin, glucose, Met-enkephalin and corticosterone in 14-week-old chickens [design: 2 sex × 2 stress/non-stress × 2 +/

Capillary HPLC Separation of Selected Neuropeptides [PDF]

open access: yes, 2012
Neuropeptides play a pivotal role in brain and peripheral nervous system function. As high performance liquid chromatography (HPLC) becomes the central tool in the separation and characterization of peptide and protein samples, its selectivity ...

Differential Changes in Striatal Projection Neurons in R6/2 Transgenic Mice for Huntington's Disease

open access: yesNeurobiology of Disease, 2002
In early adult-onset Huntington's disease (HD), enkephalinergic striatopallidal projection neurons show preferential loss, reduced preproenkephalin (PPE) expression in surviving striatopallidal neurons, and loss of fibers in their projection target area.

Double labelling immunohistochemical characterization of autonomic sympathetic neurons innervating the sow retractor clitoridis muscle [PDF]

open access: yes, 2008
Retrograde neuronal tracing and immunohistochemical methods were used to define the neurochemical content of sympathetic neurons projecting to the sow retractor clitoridis muscle (RCM). Differently from the other smooth muscles of genital organs, the RCM

Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]

open access: yes, 1982
A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...
