Nicotine Effects and the Endogenous Opioid System

Journal of Pharmacological Sciences, 2014
.: Nicotine (NIC) is an exogenous ligand of the nicotinic acetylcholine receptor (nAChR), and it influences various functions in the central nervous system. Systemic administration of NIC elicits the release of endogenous opioids (endorphins, enkephalins,

Mass Spectrometry Imaging Combined With Single‐Cell Transcriptional Profiling Reveals the Multidimensional Spatial Distributions and Biosynthetic Pathways of Medicinal Components in Andrographis paniculata

Plant Biotechnology Journal, Volume 24, Issue 5, Page 2876-2890, May 2026.
ABSTRACT The synthesis and accumulation of active ingredients in medicinal plants are distributed in specific organs, tissues, and cell types, which are important for the exploitation of medicinal plants. However, the fine distribution of active ingredients is difficult to know. Here, the system of mass spectrometry imaging (MSI) integrated with single‐

Recent Advancements in the Characterization of D‐Amino Acid and Isoaspartate Post‐Translational Modifications

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 218-230, March/April 2026.
ABSTRACT One of the great triumphs of mass spectrometry‐based peptide and protein characterization is the characterization of their modifications as most modifications have a characteristic mass shift. What happens when the modification does not change the mass of the peptide?

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐

Hyperpolarization Modulation of the T‐Type hCav3.2 Channel by Human Synenkephalin [1–53], a Shrew Neurotoxin Analogue without Paralytic Effects

Angewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

Cerebrospinal Fluid Proenkephalin Predicts Striatal Atrophy Decades before Clinical Motor Diagnosis in Huntington's Disease

Movement Disorders, Volume 41, Issue 1, Page 95-106, January 2026.
Abstract Background Huntington's disease (HD) is characterized by early, selective, progressive vulnerability of striatal medium spiny neurons (MSNs). Proenkephalin (PENK), a precursor of opioid peptides abundantly expressed in MSNs, is a promising biomarker of striatal integrity, but region‐specific associations and its potential for early‐stage ...

Metabolic signatures of the integrated profile of cardiovascular autonomic modulation and cardiorespiratory fitness in apparently healthy individuals

Physiological Reports, Volume 14, Issue 2, January 2026.
Abstract Cardiovascular autonomic modulation (CAM) and cardiorespiratory fitness (CRF) are well‐established predictors of health. Identifying metabolites associated with integrated CAM‐CRF profiles may help characterize healthy physiological states.

Characterization and Identification of Potential Antioxidant, Antidiabetic, and Antihypertensive Peptides From Hydrolysates of Tenebrio molitor Flour and Its Protein Concentrate

Journal of Food Science, Volume 90, Issue 10, October 2025.
ABSTRACT Insects are recognized as a potential alternative source of proteins and have been studied in recent years as a substrate for enzymatic hydrolysis to obtain bioactive peptides. This study aimed to evaluate the production of hydrolysates with antioxidant, antidiabetic, and antihypertensive properties from mealworm (Tenebrio molitor) flour and ...

Lentil Flours as Sustainable Source of Proteins for the Food Industry

Sustainable Food Proteins, Volume 3, Issue 3, September 2025.
Lentils, due to their accessibility, sustainability, and high nutritional value, emerge as a promising option as protein flour for food development. This study evaluated different functional and nutritional properties of lentil flours. ABSTRACT The growing transition toward a plant‐based diet, coupled with the need for sustainable dietary protein ...
