A RP-HPLC method was established for simultaneous determination of phellodendrine hydrochloride (PH1), magnoflorine hydrochloride (MH), jatrorrhizine hydrochloride (JH), palmatine hydrochloride (PH2) and berberine hydrochloride (BH) in Phellodendri Chinensis Cortex by using ionic liquids as mobile phase additives. The separation was performed on a Kromasil C18 (4.6 mm x 250 mm, 5 μm) coupled with ultraviolet (UV) detection. The effect of extraction solvent, detection wavelength, length of alkyl chain on different imidazolium ionic liquids and concentration of ionic liquids on the separation and determination of alkaloids were investigated. Ionic liquid, [BMIm] BF4, can obviously improve the resolution and peak shape. This ILs-HPLC method is simple, rapid, and reliable, which can be used for determination of alkaloids in Phellodenddri Chinensis Cortex.

Acute kidney injury (AKI) is a group of common clinical syndromes characterized by a rapid decline in renal function over a short period of time. At present, the treatment methods are limited, and research is needed to identify drugs that could alleviate renal ischemia-reperfusion (I/R) injury. Tetramethylpyrazine (TMP) is a bioactive alkaloid extracted from the Chinese herbal medicine Chuanxiong.

Over 1200 heavy feedlot cattle presented with severe tongue lesions during a 7-month interval. Review of the literature and discussions with colleagues revealed previous similar outbreaks had occurred in Canada and the USA, with extensive investigations conducted and no cause identified. In the current outbreak, examination of the environment, feed, water, cattle behavior, and husbandry systems were conducted, as well as diagnostic testing including necropsy, histopathology, bacteriology, virology, and toxicology.

Pleural effusions (PLEF) in pulmonary arterial hypertension (PAH), particularly in patients with isolated right heart failure, are associated with poor prognosis and increased mortality. This study investigates changes in alveolar fluid clearance (AFC) transporter expression in relation to lung fluid accumulation and PLEF formation during PAH progression, as well as the effects of terbutaline (TER) and riociguat (RIO) treatment. Using a monocrotaline (MCT)-induced pulmonary hypertension (PH) rat model, we performed a detailed molecular analysis of AFC transporter expression at different disease stages, both before and after PH development.

The PR10 (Pathogenesis-Related Protein 10) family plays a crucial role in plant defense and growth regulation, with unique hydrophobic cavities that bind various ligands, including phytohormones and alkaloids. Among them, Norcoclaurine Synthases (NCS) are key enzymes in benzylisoquinoline alkaloid (BIAs) biosynthesis, catalyzing the Pictet-Spengler reaction to form the precursor (S)-norcoclaurine. However, the evolutionary origins and functions of the PR10 family in BIA biosynthesis remain unclear.
