OBJECTIVES
The study provides a thorough examination of the rhizomes of Roxb., which is a medicinal substance sometimes referred to as black turmeric and has not been well studied.
METHODS
The study examines the pharmacognostical characteristics, GC-MS profiling, and elemental analysis of the substance to determine its potential for use in medicine. The presence of heavy metal contamination in herbal products is a significant issue, which necessitates the use of Atomic Absorption Spectrophotometry to quantitatively analyze eight elements.
RESULTS
The investigation validates the existence of crucial trace elements while guaranteeing that the levels of heavy metals are within the toxicity limits set by the World Health Organization. This indicates that the rhizome is safe for medicinal purposes. The selection of a solvent has a substantial impact on the efficiency of extraction. Acetone has the highest extraction yield, followed by ethanol and ethyl acetate. The GC-MS analysis uncovers a wide range of phytochemicals, such as alkaloids, flavonoids, phenols, tannins, steroids, and proteins. Additionally, particular solvents exclusively detect specific molecules. Epicurzerenone and zederone are chemicals that show promise for use in reducing inflammation and fighting cancer.
CONCLUSIONS
On the basis of results it can be concluded that rhizome's quality based on acceptable physicochemical characteristics and provides a strong basis for future pharmacological research. The research has potential for the development of novel organic drugs, utilizing the abundant phytochemical composition of Roxb. rhizomes.

We read with interest the article by Kulesza et al. about a narrative review on the question of whether cannabidiol is really effective in treating lower back pain [1]. After a literature search using suitable search terms and application of inclusion and exclusion criteria, the authors included 10 studies in the analysis [1]. One of the articles included was an editorial and four papers were reviews [1]. Cannabidiol has been found to be ineffective in treating lower back pain and further studies are needed to answer the question of interest. The review is impressive, but several points require discussion.

A 1-year-old Miniature Horse filly was presented for chronic lethargy and hyporexia. Elevated liver enzymes, bile acids, and ammonia were noted on bloodwork. The primary differential diagnosis was a portosystemic shunt (PSS). Three-phase computed tomographic angiography findings were consistent with a transhepatic portosystemic shunt. Percutaneous liver biopsy confirmed severe diffuse hepatic changes, most likely due to chronic pyrrolizidine alkaloid toxicosis, and medical management was elected. Based on an extensive literature review, this is the first report of a transhepatic portosystemic collateral vessel in a horse. Computed tomographic angiography is feasible and useful for the diagnosis of PSS in miniature horses.

BACKGROUND
Persistent hyperuricemia can lead to the generation and deposition of monosodium urate (MSU) crystals. This can trigger gouty arthritis (GA), which in turn induces inflammation. Activation of the Nod-like receptor pyrin domain containing 3 (NLRP3) inflammasome plays a critical role in the onset and progression of GA. Autophagy may have a dual effect on GA with regard to the NLRP3 inflammasome. Therefore, the present study aimed to gain a deeper comprehension of the interaction between autophagy and NLRP3 inflammasome activation is imperative for developing more efficacious treatments for GA.
METHODS
Peripheral blood monocytes (PBMCs) were first isolated from GA patients and healthy controls and underwent bulk RNA sequencing analysis. Overexpression and knockdown of dual specificity phosphatase 1 (DUSP1) was performed in THP-1 monocytes to investigate its role in the immune response and mitochondrial damage. The luciferase assay and Western blot analysis were used to study the interaction between autophagy and NLRP3 inflammasome activation.
RESULTS
Bulk RNA sequencing analysis showed significant upregulation of DUSP1 expression in PBMCs from GA patients compared to healthy controls. This result was subsequently verified by reverse transcription quantitative polymerase chain reaction (RT-qPCR). DUSP1 expression in human THP-1 monocytes was also shown to increase after MSU treatment. Downregulation of DUSP1 expression increased the secretion of inflammatory cytokines after MSU treatment, whereas the overexpression of DUSP1 decreased the secretion levels. Lipopolysaccharides (LPS) combined with adenosine-triphosphate (ATP) led to mitochondrial damage, which was rescued by overexpressing DUSP1. DUSP1 overexpression further increased the level of autophagy following MSU treatment, whereas downregulation of DUSP1 decreased autophagy. Treatment with the autophagy inhibitor 3-Methyladenine (3-MA) restored inflammatory cytokine secretion levels in the DUSP1 overexpression group. MSU caused pronounced pathological ankle swelling . However, DUSP1 overexpression significantly mitigated this phenotype, accompanied by significant downregulation of inflammatory cytokine secretion levels in the joint tissues.
CONCLUSIONS
This study revealed a novel function and mechanism for DUSP1 in promoting autophagy to mitigate the MSU-induced immune response in GA. This finding suggests potential diagnostic biomarkers and anti-inflammatory targets for more effective GA therapy.

is a relatively small genus belonging to the tribe Senecioneae (Fam. Asteraceae), distributed in Asia, Europe, and North Africa. Some of its species are considered toxic due to the presence of pyrrolizidine alkaloids whereas some other ones are largely utilised in the ethnopharmacology of several countries. In the present study, the essential oil composition of a Sicilian accession of M. Bieb (syn. Hoffm.), not previously investigated, is particularly rich in sesquiterpene hydrocarbons (80.3%) with germacrene D (58.9%), -humulene (8.8%), and -caryophyllene (6.5%) as main metabolites. A comparison with all the essential oils from taxa studied so far has been carried out.

Exploring prescribing trends and economic burden of chronic low back pain (cLBP) patients prescribed buprenorphine buccal film (Belbuca®) or transdermal patches. In the MarketScan® commercial insurance claims (employees and their spouses/dependents, 2018-2021), the first film or patch prescription date was an index event. The observation covered 6-month pre-index and 12-month post-index periods. Patients were propensity-score matched (708 per cohort). Buprenorphine initiation had stable cost trends in buccal film and increasing trends in transdermal patch cohort. Between-cohort comparisons of healthcare expenditures, cost trends and resource utilization showed significant differences, mostly in favor of buccal film. Buccal film also had higher daily doses and wider dosing range. Buprenorphine film is more cost-effective cLBP treatment with more flexible dosing.

Review
Fungi are a large group of eukaryotic microorganisms that can readily adapt to diverse environments and occur in almost all climatic zones and continents. Although some fungi are inevitable in the environment for the decay and recycling of organic material, many species are known to produce secondary metabolites, and these mycotoxins, when ingested with food or feed materials, can adversely affect animal and human health. Among the toxigenic fungi, species are recognized as so-called field fungi, invading crops and producing mycotoxins predominantly before harvest. produces a wide array of mycotoxins, causing different plant diseases. Fusariosis causes significant economic losses in a wide range of crops. secondary metabolites, particularly trichothecenes, are potent toxins in mammalian species and cause diverse adverse effects in humans and animals. Other prominent toxins with entirely different chemical structures are zearalenone and its derivatives and fumonisins. With an entirely different life cycle, toxins of endophytes belonging to the genus Epichloë and and comprise an animal health risk, particularly for grazing animals. This review aimed to summarize the adverse effects of selected and toxins, with a special emphasis on their occurrence in roughages and their mechanisms of action, and describe their effect on animal health and welfare and the potentially related public health risks.

Mesaconitine (MA), a diester-diterpenoid alkaloid extracted from the medicinal herb , is commonly used to treat various diseases. Previous studies have indicated the potent toxicity of aconitum despite its pharmacological activities, with limited understanding of its effects on the nervous system and the underlying mechanisms. HT22 cells and zebrafish were used to investigate the neurotoxic effects of MA both and , employing multi-omics techniques to explore the potential mechanisms of toxicity. Our results demonstrated that treatment with MA induces neurotoxicity in zebrafish and HT22 cells. Subsequent analysis revealed that MA induced oxidative stress, as well as structural and functional damage to mitochondria in HT22 cells, accompanied by an upregulation of mRNA and protein expression related to autophagic and lysosomal pathways. Furthermore, methylated RNA immunoprecipitation sequencing (MeRIP-seq) showed a correlation between the expression of autophagy-related genes and N6-methyladenosine (m6A) modification following MA treatment. In addition, we identified METTL14 as a potential regulator of m6A methylation in HT22 cells after exposure to MA. Our study has contributed to a thorough mechanistic elucidation of the neurotoxic effects caused by MA, and has provided valuable insights for optimizing the rational utilization of traditional Chinese medicine formulations containing aconitum in clinical practice.
