Nicotine is a psychostimulant that induces neurochemical and behavioral changes upon chronic administration, leading to neurodegenerative conditions associated with smoking. As of now, no preventive or therapeutic strategies are known to counteract nicotine‑induced neurodegeneration. In this study, we explore the neuroprotective effects of crocin, a bioactive agent commonly found in saffron - a spice derived from the flower of Crocus sativus - using a rat model. The dose‑dependent effects of crocin were evaluated in nicotine‑induced neurodegeneration and compared with a control group...

Areca nut (AN) is a carcinogen; its chewing cessation is, therefore, of worldwide interest. However, cessation biomarkers are lacking. We sought to establish arecoline in chewers' buccal cells (BCs) as a biomarker for AN dose. Self-reported AN doses, expressed as the average AN load ("AANL"), the product of AN amount, chewing time, and chewing frequency, were correlated by regression analysis with chewers' BC arecoline, measured by liquid chromatography mass spectrometry. We then determined whether associations differed between Class 1 chewers (who consume AN alone or with slaked lime, leaf, and/or spices) and Class 2 chewers (who consume any combination of the aforementioned ingredients plus tobacco)...

BACKGROUND: The determination of genome size is a fundamental step which provides a basis to initiate studies aimed at deciphering the genetic similarity of a species and to carry out other genomics based investigations. Fenugreek (Trigonella spp.) is an important spice crop which has numerous health promoting phytochemicals. Many species within this genus are known for their various health benefits owing to the presence of a wide diversity of important phytochemicals like diosgenin, trigonelline, fenugreekine, galactomannan, 4-hydroxy isoleucine, etc...

Aroma profiling using HS-SPME coupled to GC-MS analysis and in the context of autoclave treatment led to the detection of a total of 52 volatiles with an abundance of β-caryophyllene at 82% and 59% in black and white pepper, respectively...

Crocus sativus (saffron) is a globally autumn-flowering plant, and its stigmas are the most expensive spice and valuable herb medicine. Crocus specialized metabolites, crocins, are biosynthesized in distant species, Gardenia (eudicot) and Crocus (monocot), and the evolution of crocin biosynthesis remains poorly understood. With the chromosome-level Crocus genome assembly, we revealed that two rounds of lineage-specific whole genome triplication occurred, contributing important roles in the production of carotenoids and apocarotenoids...

In order to maintain the dynamic physiological balance, plants are compelled to adjust their energy metabolism and signal transduction to cope with the abiotic stresses caused by complex and changeable environments. The diterpenoid natural compound and secondary metabolites, sclareol, derived from Salvia sclarea, has gained significant attention owing to its economic value as a spice material and diverse physiological activities. Here, we focused on the roles and regulatory mechanisms of the sclareol diterpene synthase gene SsdTPS in the resistance of S...

Recreational use of synthetic cannabinoid agonists (i.e., "Spice" compounds) that target the Cannabinoid Type 1 receptor (CB 1 ) can cause respiratory depression in humans. However, Δ 9 -tetrahydrocannabinol (THC), the major psychoactive phytocannabinoid in cannabis, is not traditionally thought to interact with CNS control of respiration, based largely upon sparse labeling of CB1 receptors in the medulla and few reports of clinically significant respiratory depression following cannabis overdose. The respiratory effects of CB 1 agonists have rarely been studied in vivo , suggesting that additional inquiry is required to reconcile the conflict between conventional wisdom and human data...

BACKGROUND: Carvone is a monoterpene ketone in mint plants and some Mediterranean spices. In Carvone, chemical compounds occur in two enantiomers, S (+) carvone and R (-) carvone. These two enantiomeric forms of carvone are identical in terms of their physical and chemical characteristics and only differ in terms of their rotatory power based on their smell. Caraway has also been utilized to treat newborns' flatulent colic and to treat adults' anxious cardiac- gastric symptoms, spasmodic gastrointestinal complaints, flatulence, irritated stomach, indigestion, lack of appetite, and dyspepsia...

BACKGROUND AND OBJECTIVES: The potential for synthetic cannabinoids (SCs) to function as an alternative to marijuana without the same risk of a positive urinalyses led to claims of pervasive military SC use. Case studies confirm use among veterans, but no study has adequately explored SC use in the military using detailed interview data. METHODS: Interviews (1-2 h) were conducted with 318 justice-involved veterans. Recruitment was attempted with all participants in eight veterans treatment courts in three U...
