Alprazolam-associated death: suicide or unintentional overdose?

Alprazolam is a psychoactive triazolo-benzodiazepine, commonly prescribed for the treatment of anxiety disorders and considered safe due to its high therapeutic index. It is frequently detected in polydrug-related deaths but there are very few cases of fatal intoxication by alprazolam not in combination with alcohol or other drugs. A fatal poisoning by alprazolam in a 60-years old male physician has been reported. At autopsy, no evidence of traumatic injuries or diseases was observed except for signs of bronchopneumonia and slight hypertrophy of the left ventricle. Alprazolam and its major metabolite (alpha-hydroxyalprazolam) were detected in biological samples through liquid chromatography-tandem mass spectrometry (LC-MS/MS). High concentrations of alprazolam and alpha-hydroxyalprazolam were found, respectively, in femoral blood 0.45 and 0.03 mg/L, urine 2.12 and 0.42 mg/L, bile 1.33 and 0.56 mg/L, liver 3.81 and 0.28 mg/L. Alprazolam alone was also detected in vitreous humour (0.19 mg/L) and in stomach content (0.34 mg/L). No conclusive information confirmed the hypothesis of a suicidal ingestion of alprazolam. However, an alprazolam drug-related death was assessed based on the pre-existing cardiovascular and respiratory defects. The high levels of alprazolam several times greater than the therapeutic range contributed to death due to its respiratory and central nervous system-depressant effects.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 927-74-2, you can contact me at any time and look forward to more communication. Safety of 3-Butyn-1-ol.

Optimization of pretreatment and enzymatic hydrolysis conditions of tomato pomace for production of alcohols and esters by Kluyveromyces marxianus

Tomato pomace (TP) is generated as a natural by product in a significant amount in the tomato processing industry, and it is a good source of lignocelluloses to produce some high-value products from fermentable sugars (FS). The present study was performed to produce FS by using either ultrasound-assisted dilute acid (UADA) or heat-treated dilute acid (HTDA) pretreatments of TP followed by enzymatic hydrolysis (EH). When HTDA and UADA were compared in terms of FS (g/L) concentration, HTDA pretreatment generally produced more FS content than UADA. The optimum conditions for HTDA pretreatment were the application of 2.5% H2SO4, 10% (w/v) solution of TP, and heating at 121 degrees C for 6 min, which yielded 31 g/L FS concentration. Beside the optimized conditions for EH of HTDA, pretreated TP required 1.5% of enzyme concentration and 6 h of hydrolysis time. In conclusion, the most abundant volatile organic compounds (VOCs) produced by K. marxianus in final tomato pomace hydrolysate (TPH) were isoamyl alcohol, phenyl ethyl alcohol, ethyl acetate and phenyl ethyl acetate in a 5-L bioreactor. Nine descriptive sensory terms were developed to characterize fermented TPH. The rose and sweet floral aromas were defined as aroma characteristics for TPH fermented by K. marxianus.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 927-74-2, in my other articles. SDS of cas: 927-74-2.

The chemical composition and potential role of epicuticular and intracuticular wax in four cultivars of table grapes

Plant cuticular wax is the first barrier to resist biotic and abiotic stress. However, little is known about the compositional differences between the epicuticular and intracuticular wax in grape berry. The compositional, morphological and functional features of cuticular wax in grape berries of Vitis vinifera cv. ‘Kyoho’, ‘Muscat Hamburg’, ‘Redglobe’, and ‘Zuijinxiang’ were investigated. The total and epicuticular wax of four berries were mainly composed of terpenoids, hydrocarbons, alcohols, fatty acids and esters. Oleanolic acid was the most abundant terpenoid among the four cultivars. Scanning electron microscopy revealed the crystalline flakes structure of the cuticular wax. Additionally, the removal of epicuticular wax accelerated the weight loss, browning, and softening of grape berries, indicating the plastic-wrap-like effect of the cuticular wax on postharvest quality. This study provided the theoretical basis for further application of the fruit wax or waxy analogue.

Epidemiology and risk of psychiatric disorders among patients with celiac disease: A population-based national study

Background and Aim Celiac disease (CD) is a chronic disorder resulting from an immune reaction to gluten in genetically predisposed individuals. Although several studies have linked CD to psychiatric diseases, there are limited data on this topic. Using a large database, we sought to describe the epidemiology of several psychiatric disorders in CD. Methods We queried a multicenter database (Explorys Inc), an aggregate of electronic health record data from 26 major integrated healthcare systems from 2016 to 2020 consisting of 360 hospitals in the USA. A cohort of patients with a Systematized Nomenclature Of Medicine – Clinical Terms diagnosis of CD was identified. Multivariate analysis was performed using Statistical Package for Social Sciences version 25. Results Of the 37 465 810 patients in the database between 2016 and 2020, there were 112 340 (0.30%) individuals with CD. When compared with patients with no history of CD, patients with CD were more likely to have a history of anxiety (odds ratio [OR]: 1.385; 95% confidence interval [CI]: 1.364-1.407), depression (OR: 1.918; 95% CI: 1.888-1.947), bipolar (OR: 1.321; 95% CI: 1.289-1.354), attention-deficit hyperactivity disorder (OR: 1.753; 95% CI: 1.714-1.792), eating disorder (OR: 15.84; 95% CI: 15.533-16.154), and childhood autistic disorder (OR: 4.858; 95% CI: 3.626-6.508). Patients with CD and psychiatric conditions were more likely to be smokers, with history of alcohol and substance abuse as well as a history of personality disorder. Conclusions In this large database, patients with CD are at increased risk of having multiple psychiatric diseases including anxiety, depression, bipolar, attention-deficit hyperactivity disorder, eating disorder, and childhood autism. Individual care and referral to psychiatry when appropriate are warranted while taking care of this group of patients.
