Dementias is a kind of neurodegenerative disease, which occurs among the aging population. Current therapeutic outcome for dementia is limited. The medical use of herbal plant has a rich history in traditional Chinese medicine practice for thousands of years. Herbal medicine (HM) may provide a positive effect for prevention and treatment in dementia. As an alternative treatment to dementia, there has been a growing interest in HM extracts in scientific community as a result of its promising study results, mainly in animal experiment. At the molecular level, HM extracts trigger autophagy and reduce generation of reactive oxygen species (ROS) while inhibiting inflammation and reduce neurotoxicity. Experiments both and have identified certain potential of HM extracts and natural products as an important regulator factor in mediating autophagy, which might contribute to the improvement of dementia. This brief review not only summarizes the mechanism of autophagy in dementia but also offers a general understanding of the therapeutic mechanism of HM extracts in treating dementia and evaluates the potential clinical practice of HM in general.

Background: Vascular calcification is a detrimental aging pathology markedly accelerated in patients with chronic kidney disease. Prelamin A is a biomarker of vascular smooth muscle cell aging that accelerates calcification however the mechanisms remain undefined.
Methods: Vascular smooth muscle cells were transduced with prelamin A using an adenoviral vector and epigenetic modifications were monitored using immunofluorescence and targeted polymerase chain reaction array.
Swords and shields: the war between Liberibacter asiaticus and citrus.

Citrus Huanglongbing (HLB) represents a significant threat to the citrus industry, mainly caused by the phloem-limited bacterium Liberibacter asiaticus (Las). In this review, we summarize recent advances in understanding the relationship between citrus and Las, particularly examining the functions of Sec-dependent effectors (SDEs) and non-classically secreted proteins (ncSPs) in virulence, as well as their targeted interactions with citrus. We further investigate the impact of SDEs on various physiological processes, including systemic acquired resistance (SAR), reactive oxygen species (ROS) accumulation, vesicle trafficking, callose deposition, cell death, autophagy, chlorosis and flowering.

Background: Parkinson's disease (PD) is characterized by dopaminergic (DA) neuron loss, Lewy body build-up, and motor dysfunction. One of the primary pathogenic mechanisms of PD development is autophagy dysfunction and nitric oxide-mediated neurotoxicity.
Purpose: The current study focuses on autophagy and nitric oxide (NO) signaling roles in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-intoxicated PD mice and their protection by their modulators.
Nature's magic: how natural products work hand in hand with mitochondria to treat stroke.

Background: Mitochondria, as the energy factories of cells, are involved in a wide range of vital activities, including cell differentiation, signal transduction, the cell cycle, and apoptosis, while also regulating cell growth. However, current pharmacological treatments for stroke are challenged by issues such as drug resistance and side effects, necessitating the exploration of new therapeutic strategies.
Objective: This review aims to summarize the regulatory effects of natural compounds targeting mitochondria on neuronal mitochondrial function and metabolism, providing new perspectives for stroke treatment.
