Objectives The juice extract of Cyperus esculentus commonly known as tiger nuts (TINUT) is widely used for its numerous health promoting effects including alleviation of symptoms associated with neurological disorders. Herein, we investigated the influence of the aqueous extract of C. esculentus on cognitive disorder and the underlying changes in acetylcholinesterase (AChE) activity and oxidative stress biomarkers in mice exposed to scopolamine. Methods C. esculentus (50-200 mg/kg) or saline (10 mL/kg) was given alone or with scopolamine 30 min after, to male Swiss mice (6/group) daily for seven days. We evaluated the cognitive performance using Y-maze and object recognition on day seven post-treatment. Brains of the animals were afterwards processed for spectrophotometric determination of AChE activity and contents of oxidative stress biomarkers (malondialdehyde [MDA], glutathione [GSH], catalase, superoxide dismutase and nitrite). Results The extract improves cognitive function and also upturned scopolamine amnesia in mice. The extract markedly reduced brain AChE, MDA, and nitrite contents in mice injected with scopolamine (p<0.05). It also attenuated scopolamine-induced deregulated GSH contents and antioxidant enzymes in mouse brain. Conclusions The results of this study suggest that regular consumption of TINUT might offer beneficial effects in memory-related disorders.

Exposure to vanadium (V) occurs through the ingestion of contaminated water, polluted soil, V-containing foods and medications, and the toxicity and absorption during the small intestine phase after oral ingestion play crucial roles in the ultimate health hazards posed by V. In this study, the human colon adenocarcinoma (Caco-2) cells were selected as an intestinal absorption model to investigate the uptake and cytotoxicity of vanadyl sulfate (VOSO) and sodium orthovanadate (NaVO). Our results confirmed the cytotoxic effects of V(IV) and V(V) and revealed a greater toxicity of V(IV) than V(V) towards Caco-2 cells.

The study aimed to elucidate the underlying pharmacological mechanism of the traditional Chinese medicine Pue in ameliorating myocardial ischemia-reperfusion injury (MIRI), a critical clinical challenge exacerbated by reperfusion therapy. In vivo MIRI and in vitro anoxia/reoxygenation (A/R) models were constructed. The results demonstrated that Pue pretreatment effectively alleviated MIRI, as manifested by diminishing the levels of serum CK-MB and LDH, mitigating the extent of myocardial infarction and enhancing cardiac functionality.

Loss-of-function mutations in PARK7, encoding for DJ-1, can lead to early onset Parkinson's disease (PD). In mice, Park7 deletion leads to dopaminergic deficits during aging, and increased sensitivity to oxidative stress. However, the severity of the reported phenotypes varies.

Nuclear speckles are membraneless organelles that associate with active transcription sites and participate in post-transcriptional mRNA processing. During the cell cycle, nuclear speckles dissolve following phosphorylation of their protein components. Here, we identify the PP1 family as the phosphatases that counteract kinase-mediated dissolution.

Objective: Electroacupuncture has been shown to play a neuroprotective role following ischemic stroke, but the underlying mechanism remains poorly understood. Ferroptosis has been shown to play a key role in the injury process. In the present study, we wanted to explore whether electroacupuncture could inhibit ferroptosis by promoting nuclear factor erythroid-2-related factor 2 (Nrf2) nuclear translocation.
