Objective: Magnesium (Mg) deficiency may accelerate neurodegenerative disease progression, but current cognitive impairment biomarkers have significant limitations. This study aimed to investigate the association between Mg depletion score (MDS) and cognitive impairment.

Design: This study is a cross-sectional analysis using data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES) to examine the relationship between MDS and cognitive performance.

Background: Posterior reversible encephalopathy syndrome (PRES) is characterized by headaches, vision loss, confusion, encephalopathy, seizures, and reversible focal edema on neuroimaging. Early recognition and treatment of PRES are essential to prevent severe complications. Lenvatinib is a multi-targeted kinase inhibitor that is used as a first-line treatment for patients with hepatocellular carcinoma (HCC).

Obesity is a major cause of nonalcohol fatty liver disease (NAFLD), which is characterized by hepatic fibrosis, lipotoxicity, inflammation, and apoptosis. Previous studies have shown that an imbalance in the autonomic nervous system is closely related to the pathogenesis of NAFLD. In this study, we investigated the effects of pyridostigmine (PYR), a cholinesterase (AChE) inhibitor, on HFD-induced liver injury and explored the potential mechanisms involving mitochondrial damage and oxidative stress.

Background: The mitochondrial unfolded protein response (UPR) is the first line of defense against mitochondrial dysfunction in several diseases. Baicalein, which is an extract of Scutellaria baicalensis Georgi roots, exerts mitoprotective effects on metabolic disorders and cardiovascular diseases. However, it remains unclear whether baicalein alleviates obesity-induced cardiac damage through the UPR.

Carbapenems are considered the last line of defence against bacterial infections, but their high consumption and the resulting antibacterial resistance are an increasing global concern. In this context, the Chinese health authority issued an expert consensus on the clinical applications of carbapenems. However, the long- and short-term effects of the expert consensus on carbapenem use are not clear.

Lipid droplets (LDs), which are neutral lipid storage organelles, are important for lipid metabolism and energy homeostasis. LD lipolysis and interactions with mitochondria are tightly coupled to cellular metabolism and may be potential targets to buffer the effects of excessive toxic lipid species levels. Acetylcholine (ACh), the major neurotransmitter of the vagus nerve, exhibits cardioprotective effects.

Article Synopsis
  • Mitochondrial dysfunction contributes to heart changes caused by obesity, where cristae (the inner folds of mitochondria) play a key role in cell energy production.
  • The study found that palmitate caused alterations in the structure of cristae in heart cells from neonatal rats, leading to increased cell size and damaged mitochondrial function.
  • Acetylcholine (ACh) was shown to protect against these changes by enhancing mitofilin levels and activating AMPK, which helps maintain mitochondrial integrity and prevents heart cell enlargement caused by palmitate.

Obesity is an important risk factor for cardiovascular diseases, which can lead to a variety of cardiovascular diseases including myocardial remodeling. Obesity may induce myocardial dysfunction by affecting hemodynamics, inducing autonomic imbalance, adipose tissue dysfunction, and mitochondrial dyshomeostasis. The key necessary biochemical functions for metabolic homeostasis are performed in mitochondria, and mitochondrial homeostasis is considered as one of the key determinants for cell viability.

Aims: Obesity is associated with increased cardiovascular morbidity and mortality. It is accompanied by augmented O-linked β-N-acetylglucosamine (O-GlcNAc) modification of proteins via increasing hexosamine biosynthetic pathway (HBP) flux. However, the changes and regulation of the O-GlcNAc levels induced by obesity are unclear.

Article Synopsis
  • Insulin resistance and autonomic imbalance contribute to cardiac remodeling in metabolic syndrome, leading to issues like impaired insulin signaling and lipid metabolism.
  • A study found that a high-fat diet causes irregular mitochondrial cristae structure in the heart, decreasing ATP production and increasing oxidative stress, which worsens cardiac function.
  • Pyridostigmine (PYR) improves autonomic balance and mitochondrial health by enhancing vagal activity, improving mitochondrial cristae shape, and ultimately protecting against cardiac dysfunction and insulin resistance caused by a high-fat diet.

Aims: Cardiac hypertrophy is characterized by a shift in metabolic substrate utilization, but the molecular events underlying the metabolic remodelling remain poorly understood. We explored metabolic remodelling and mitochondrial dysfunction in cardiac hypertrophy and investigated the cardioprotective effects of choline.

Methods And Results: The experiments were conducted using a model of ventricular hypertrophy by partially banding the abdominal aorta of Sprague Dawley rats.

Article Synopsis
  • Ischemic heart disease (IHD) is a serious cardiovascular condition where mitochondria play a critical role in managing cell energy and signaling.
  • Mitochondrial health is maintained through processes like fission, fusion, and mitophagy, which are essential for proper cardiac function.
  • The review explores how disruptions in these mitochondrial processes are linked to ischemic heart conditions and discusses the potential protective effects of the vagal nerve on mitochondrial function.

Autonomic dysfunction and abnormal immunity lead to systemic inflammatory responses, which result in cardiovascular damage in hypertension. The aim of this report was to investigate the effects of choline on cardiovascular damage in hypertension. Eight-week-old male spontaneously hypertensive rats (SHRs) and Wistar-Kyoto rats were intraperitoneally injected with choline or vehicle (8 mg/kg/day).

Article Synopsis
  • - This study investigates how vagal nerve stimulation (VNS) protects against heart damage caused by isoproterenol (ISO) in rats by focusing on mitochondrial dynamics—specifically fission and fusion processes.
  • - Isoproterenol caused increased levels of proteins leading to mitochondrial fission and decreased fusion proteins, resulting in disrupted mitochondrial function and cardiac injury, while VNS restored balance and improved mitochondrial health.
  • - The protective effects of VNS were linked to the activation of a specific signaling pathway (M3 receptor/CaMKKβ/AMPK), suggesting that targeting mitochondrial dynamics could offer a new treatment approach for ischemic heart disease (IHD).

Acetylcholine (ACh) protected against cardiac injury via promoting autophagy and mitochondrial biogenesis, however, the involvement of mitophagy in ACh-elicited cardioprotection remains unknown. In the present study, H9c2 cardiomyocytes were subjected to hypoxia/reoxygenation (H/R) and ACh treatment during reoxygenation. Mitophagy markers PTEN-induced kinase 1 (PINK1) and Parkin translocation were examined using western blot and confocal fluorescence microscopy.
