"Mutong" ( in Chinese, and generally known as Akebiae Caulis), which refers to a group of herbal medicines with different biological origins along history, has been used in traditional Chinese medicine for over 2000 years; it is still being frequently used in medicine. In recent decades, Akebiae Caulis has been reported to exhibit apparent toxicity.

To clarify the plant species used as Akebiae Caulis and its synonyms, and to summarize their phytochemistry, pharmacology, and toxicology.

Academic search engines (Google Scholar, Baidu Scholar, CNKI, Science Direct, Springer Link, SciFinder, PubMed, Web of Science, and EBSCO), ancient Chinese herbals, and modern medical monographs were used to obtain phytochemical, pharmacological, toxicological, and quality control information. Furthermore, a field survey was conducted to clarify the associated species.

Akebiae Caulis is derived from eight species belonging to two families. In the 2005 Pharmacopoeia of The People's Republic of China, it has been separateebiae Caulis such as this one would provide solid references for its safe use, as well as drug discovery studies in the future.
Clarifying the biological origin of traditional herbal medicines is critical for their safe and effective use. The present review revealed that the biological origin of Akebiae Caulis is diverse. The traditional uses, phytochemistry, and pharmacology of Akebiae Caulis indicate that it is a useful medical resource. The diversity of its biological and pharmacological activities is associated with the presence of a large number of chemical substances, among which terpenoids are predominant. Systematic reviews on Akebiae Caulis such as this one would provide solid references for its safe use, as well as drug discovery studies in the future.
Anemarrhena asphodeloides is the dry rhizome of Anemarrhena asphodeloides Bge. Anemarrhena Saponins isolated from Anemarrhena asphodeloides are one of the pharmacologically active components of this plant and have blood lipid reduction and blood glucose reduction properties. These facts suggest that these saponins might be helpful in the treatment of insulin resistance.

To determine the therapeutic effect of anemarrhena saponins on insulin resistance and the probable underlying mechanism.

Insulin-resistant rats were used as the experimental subject, to observe the therapeutic effect of anemarrhena saponins. The blood glucose and blood lipid parameters were determined using the relevant kits. We used hematoxylin and eosin (H&E) staining to observe the protective effect of anemarrhena saponins on the livers of insulin-resistant rats and reverser transcripition polymerase chain reaction (RT-PCR) to analyze the mRNA expressions patterns of genes related to glucose metabolism and inflammatory factors. Thay, thereby reducing the damage caused by insulin resistance.Epidemiological studies have associated long-term exposure to environmental air pollution particulate matter (PM) with the development of diverse health problems. They include infectious respiratory diseases related to the deregulation of some innate immune response mechanisms, such as the host defense peptides' expression. Herein, we evaluated in BALB/c mice the effect of long-standing exposure (60 days) to urban-PM from the south of Mexico City, with aerodynamic diameters below 2.5 μm (PM2.5) and 10 μm (PM10) on the lung's gene expression and production of three host defense peptides (HDPs); murine beta-defensin-3, -4 (mBD-3, mBD-4) and cathelin-related antimicrobial peptide (CRAMP). We also evaluated mRNA levels of Il1b and Il10, two cytokines related to the expression of host defense peptides. PD-0332991 research buy Exposure to PM2.5 and PM10 differentially induced lung inflammation, being PM2.5, which caused higher inflammation levels, probably associated with a differential deposition on the airways, that facilitate the interaction with alveolar macrophages. Inflammation levels were associated with an early upregulation of the three HDPs assessed and an increment in Il1b mRNA levels. Interestingly, after 28 days of exposure, Il10 mRNA upregulation was observed and was associated with the downregulation of HDPs and Il1b mRNA levels. The upregulation of Il10 mRNA and suppression of HDPs might facilitate microbial colonization and the development of diseases associated with long-term exposure to PM.Cav3 channels play a critical role in maintaining calcium homeostasis, and its dysregulation is related to age-related diseases, such as age-related hearing loss (AHL). However, the underlying mechanism of the Cav3 channels involved in AHL remains unknown. Previous studies have shown that the degeneration of spiral ganglion neurons (SGNs) plays a critical role in AHL. Here, we explored the involvement of Cav3 channels in the dysregulation of SGNs in AHL. We used C57BL/6 mice as the AHL mouse model and found that the expression of Cav3 channels was increased in SGNs associated with age. The three subtypes of Cav3 channels were present in the apical, middle, and basal SGNs from young and older (AHL) mice. The immunostaining data suggest that Cav3.1 and Cav3.2 may contribute to Cav3 upregulation in SGNs of AHL mice. Additionally, we found that calpain-2 and apoptosis-inducing factor (AIF) were activated in SGNs from AHL mice. The inhibition of Cav3 channels or calpain-2 reduced AIF-activation in SGNs may affect neuronal survival. In conclusion, the findings suggest that Cav3 channels are upregulated in SGNs from AHL mice that may contribute to the degeneration of SGNs through the calpain-2-AIF apoptosis pathway in AHL mice.
This study aimed to examine the cross-sectional and longitudinal associations of three walking parameters (frequency, duration, and intensity) with overall mental health in older adults.

A cross-sectional survey was conducted in 2014 with 1255 community-dwelling older adults aged 65years and older in Taipei, Taiwan. Among them, 408 participants completed the one-year follow-up survey in 2015. Self-reported outdoor walking during the past 7days was measured by asking the frequency, duration, and intensity. Metabolic equivalent (MET) values (<2.5, 2.5-<3.5, 3.5-<4.5, and ≥4.5 MET) were assigned to the four levels of speed (slow pace, average, brisk, and fast pace) based on the average walking distance per minute. Overall mental health was assessed using the Five-item Brief Symptom Rating Scale (BSRS-5). Multivariable linear regression models were conducted to explore the cross-sectional and longitudinal associations between outdoor walking and overall mental health, adjusting for socio-demographic factors, lifestyle behaviors, comorbidity and health status.
