This paper presents an LC/MS/MS approach for simultaneous qualitative and quantitative analysis of proprietary Chinese medicine products for the presence of toxic ingredient compounds. The target compounds include three C(19)-diterpenoid alkaloids, two quinolizidine alkaloids, two indole alkaloids and four bufadienolide steroids. They were recognized as active compounds of several toxic/potent herbal materials commonly used in the preparation of some proprietary medicine products. These toxic/potent herbal materials include Radix Aconiti Lateralis, Radix Sophorae Tonkinensis, Semen Strychni and Venenum Bufonis. In the analysis, the LC/MS/MS system was set to record the MS spectra and respective multiple reaction monitoring (MRM) signals for different target compounds after they were separated and eluted from the column. The MS spectra were used for the qualitative analysis whereas the MRM signals for the quantitative analysis. In this study, totally 12 proprietary medicine products were tested and found to contain some of the target compounds at different levels.

Background: Wearable sensor technologies, often referred to as "wearables," have seen a rapid rise in consumer interest in recent years. Initially often seen as "activity trackers," wearables have gradually expanded to also estimate sleep, stress, and physiological recovery. In occupational settings, there is a growing interest in applying this technology to promote health and well-being, especially in professions with highly demanding working conditions such as first responders.

Background: Maintaining gut health is a persistent and unresolved challenge in the poultry industry. Given the critical role of gut health in chicken performance and welfare, there is a pressing need to identify effective gut health intervention (GHI) strategies to ensure optimal outcomes in poultry farming. In this study, across three broiler production cycles, we compared the metagenomes and performance of broilers provided with ionophores (as the control group) against birds subjected to five different GHI combinations involving vaccination, probiotics, prebiotics, essential oils, and reduction of ionophore use.

Background: Osteoporosis (OP), often termed the "silent epidemic," poses a substantial public health burden. Emerging insights into the molecular functions of FBXW4 have spurred interest in its potential roles across various diseases.
Methods: This study explored FBXW4 by integrating DEGs from GEO datasets GSE2208, GSE7158, GSE56815, and GSE35956 with immune-related gene compilations from the ImmPort repository.
Emerging strategies for nitric oxide production and their topical application as nanodressings to promote diabetic wound healing.

The challenges associated with prolonged healing or non-healing of chronic diabetic wounds contribute significantly to the increased incidence of lower limb amputation. A pivotal factor in the impediment of healing is the reduced production of endogenous nitric oxide (NO) due to the hyperglycemic microenvironment typical of chronic diabetes. While both endogenous and exogenous NO have been shown to promote the healing process of diabetic wounds, the direct application of NO in wound management is limited due to its gaseous nature and the risk of explosive release.

Background: Lysinuric protein intolerance is a rare autosomal disorder caused by mutations in the Slc7a7 gene that lead to impaired transport of neutral and basic amino acids. The gold standard treatment for lysinuric protein intolerance involves a low-protein diet and citrulline supplementation. While this approach partially improves cationic amino acid plasma levels and alleviates some symptoms, long-term treatment is suggested to be detrimental and may lead to life-threatening complications characterized by a wide range of hematological and immunological abnormalities.
