Valorization of Zingiber officinale Roscoe leaf biomass: phytotoxic potential and chemical profiling toward sustainable weed management

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 8189-8201, October 2026.
Abstract BACKGROUND Zingiber officinale Roscoe is widely cultivated as a spice and functional food, generating substantial amounts of aerial biomass that is commonly discarded after harvest. Within a circular‐economy framework, this study investigated the phytotoxic potential of Z.

Simultaneous mass spectrometry imaging of multiple neuropeptides in the brain and alterations induced by experimental parkinsonism and L-DOPA therapy

open access: yesNeurobiology of Disease, 2020
Neuropeptides are important signalling molecules in the brain and alterations in their expression levels have been linked to neurological disorders such as Parkinson's disease. It is challenging to map neuropeptide changes across and within brain regions

Soybean induced resistance to Spodoptera eridania herbivory

open access: yesPest Management Science, Volume 82, Issue 10, Page 9931-9943, October 2026.
SOD, CAT, APX, PPO, KTI, and MDA levels were higher in the resistant soybean. S. eridania herbivory increased H2O2 and MDA, but decreased SOD and PPO levels. S. eridania herbivory increased KTI activity only in the resistant variety. Isoquercitrin and daidzin were exclusive to resistant and susceptible soybeans.

Fragment‐Based Screening of Heterocyclic Electrophiles Identified Acrylamide Bioisoteres for Covalent KRasG12C Inhibitors

open access: yesArchiv der Pharmazie, Volume 359, Issue 9, September 2026.
We screened acrylamide bioisosteres against KRasG12C and prioritized primary hits by their GSH reactivity, labeling efficiency and specificity. The most promising fragment was combined with a KRas‐binding scaffold. Covalent binding, inhibitory activity and selectivity were confirmed via MS, NMR, biochemical and cell viability assays.

Phytochemical Profile, Antioxidant Activity, and Anti‐Neuroinflammatory Effects of a Novel Dry Extract of Libidibia ferrea in Microglial Cells

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
A dry extract of Libidibia ferrea (DELF) exhibits a phenolic profile associated with antioxidant and anti‐inflammatory activities. Free radical scavenging is demonstrated against DPPH, hydroxyl, and superoxide radicals, together with reduced NO and IL‐6 production in BV2 microglial cells, highlighting DELF as a promising source of bioactive compounds ...

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies

open access: yesFrontiers in Pharmacology, 2015
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes

Protective Effects of Duchesnea chrysantha Ethanol Extract Against UVB‐Induced Skin Damage via Modulation of TAK1‐Associated Signaling Pathways

open access: yesChemistry &Biodiversity, Volume 23, Issue 9, September 2026.
An ethanol extract of Duchesnea chrysantha attenuates UVB‐induced oxidative stress, cell death, and inflammatory responses in keratinocytes while modulating extracellular‐matrix‐related markers in keratinocytes and dermal fibroblasts. These protective effects are associated with reduced TAK1 activation and suppression of NF‐κB, AP‐1, and MAPK signaling,

The enkephalins and opiates: structure-activity relations

open access: yes, 1977
The X-ray structures of 9 ‘opiate’ drugs which exhibit a range of pharmacological activity have been examined in detail leading to the theory that one of the reasons why the enkephalins and related peptides possess morphine-like activity is because they ...

Thrombus Metabolism‐Based Molecular Subtyping for Prognostic Risk Stratification in Acute Ischemic Stroke: A Preliminary Study

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 9, September 2026.
This study identified two metabolically distinct thrombus molecular subtypes in AIS: a lipid metabolism‐enriched subtype (C1) associated with cardioembolic stroke and poor functional outcomes, and a folate metabolism‐enriched subtype (C2) linked to atherothrombotic stroke and better prognosis. A six‐metabolite signature further demonstrated exploratory

Cancer‐related pain: A bidirectional modulator of cancer progression

open access: yesClinical and Translational Medicine, Volume 16, Issue 9, September 2026.
CRP and tumour progression engage in a dynamic, bidirectional circuit mediated by multiple mechanisms involving neuroimmunology and cancer ‐neuroscience. Analgesic interventions may affect tumour progression, while anticancer therapies can influence pain. Targeting pain in cancer may have promising therapeutic value in cancer progression.
