Drug-impaired driving is a complex area of forensic toxicology due in part to limited data concerning the type of drugs involved and the concentrations detected. This study analyzed toxicological findings in drivers from fatal motor vehicle collisions (FMVCs) in Ontario, Canada, over a one-year period using a standardized protocol. Of the 229 cases included in the study, 56% were positive for alcohol and/or drugs. After alcohol, cannabis was the most frequently encountered substance (27%), followed by benzodiazepines (17%) and antidepressants (17%). There were differences in drugs detected by age but no marked difference in drugs detected between single and multiple FMVC's. Not all drugs detected were considered impairing either due to drug type, concentration or case history. The findings indicate the importance of comprehensive drug testing in FMVCs and highlight the need to consider a variety of factors, in addition to drug type and concentration, when assessing the role of drugs in driving impairment.

Background: Skeletal muscle injury caused by excessive exercise is one of the most commonly seen clinical diseases. It is indispensable to explore drugs for treating and relieving skeletal muscle injury. Gallic acid (GA) is a polyphenolic extract that has anti-inflammatory and antioxidant biological activities.

Microbiome science has evolved rapidly in the past decade, with high-profile publications suggesting that the gut microbiome is a causal determinant of human health. This has led to the emergence of microbiome-focused biotechnology companies and pharmaceutical company investment in the research and development of gut-derived therapeutics. Despite the early promise of this field, the first generation of microbiome-derived therapeutics (faecal microbiota products) have only recently been approved for clinical use.

The use of 3D-printed electrodes is reported fabricated from in-house conductive filament composed of a mixture of recycled poly (lactic acid) (rPLA), graphite (Gpt), and carbon black (CB) for fast detection of the abused drug ketamine. Firstly, the performance of these electrodes was evaluated in comparison to 3D-printed electrodes produced employing a commercially available conductive filament. After a simple pretreatment step (mechanical polishing), the new 3D-printed electrodes presented better performance than the electrodes produced from commercial filament in relation to peak-to-peak separation of the redox probe [Fe(CN)]/ (130 mV and 759 mV, respectively), charge transfer resistance (R = 1.

Therapeutic and misuse of veterinary drugs, such as antibiotics, can increase the potential risk of residue contamination in animal-derived food products. For milk, these residual antibiotics can have an impact on efficiency in dairy processing factories, as well as economic loss, and can also cause side effects on consumer health. Lateral flow immunoassays (LFIAs) are gaining popularity for their ease of use, low cost and their fulfilment to the REASSURED (real-time connection/monitoring, easy sampling, affordable, specific, user-friendly, rapid/robust, equipment free, deliverable to end user) criteria.

Health benefit effects of bioactive compounds depend on their bioavailabilities, which could vary according to factors including food matrix and digestion environment. To understand the "bioaccessible" health benefit of red pitay pulp, the INFOGEST static in vitro simulation of gastrointestinal (GI) digestion model and targeted metabolomics method were applied to unravel the fates of bioactive compounds in the whole food of red pitaya pulp during GI digestion. The antioxidant activity as one of the health benefit indices was also assessed to compare the changes in bioactive properties of red pitaya pulp.
