Simple and sustainable three- and four-step sequences of di-OH-protection/mono-OMe-deprotection/OrgRC and di-OH-protection/mono-OMe-deprotection/OrgRC/OMe-deprotection protocols were developed to construct biologically active natural products of irisoquin, irisoquin A, irisoquin D, irisoquin F, sorgoleone-364, embelin, rapanone, 5--methylembelin, 5--methylrapanone and their analogues from the commercially available 2,5-dihydroxy-1,4-benzoquinone, aliphatic aldehydes and Hantzsch ester (1,4-DHP) in very good to excellent yields by using organocatalytic reductive coupling (OrgRC) as key reaction. Many of these natural compounds exhibited a broad spectrum of biological activities including antioxidant, anti-inflammatory, anticonvulsant, anxiolytic, analgesic, anthelmintic, antitumor, antibacterial, and antifertility properties. At the same time, simple and readily available 2,5-dihydroxy-1,4-benzoquinone was transformed into a functionally rich library of 2,5-dihydroxy-3,6-dialkyl-1,4-benzoquinones in very good yields by using sequential OrgRC followed by deprotection reactions and resulting natural/unnatural products would be excellent targets for investigation to show their biological activities compared to known natural products.

The assessment of measurement uncertainty of an analytic method is a requirement for forensic toxicologists and drug chemists. There are two main methods for estimating measurement uncertainty: the bottom-up and the top-down approaches. The bottom-up approach has been suggested in current practice guides including 'Guide to the Expression of Uncertainty in Measurement (GUM)' published by ISO, and a guide to 'Quantifying Uncertainty in Analytical Measurement' published by EURACHEM.

Since ancient times many countries have employed medicinal plants as part of traditional medicine. Anethole is a substance found in various plants and has two isomers, cis-anethole (CA) and trans-anethole (TA). Currently, the food industry extensively use anethole as an aromatic and flavoring component.

Postherpetic neuralgia (PHN) is a common chronic pain disease that persists after the rash (clusters of clear blisters on the surface of the skin) has healed, adversely affecting the quality of life of affected patients. Gabapentin (GPT) and pregabalin (PGB) are two commonly used drugs for the treatment of PHN, but there have been broad concerns regarding their efficacy and safety. Thus, this retrospective cohort study was conducted to investigate the effectiveness and safety of GPT versus PGB in the treatment of PHN.

Aims: To assess and compare the effectiveness of pharmacological and cognitive-behavioral modalities-behavioral methods (BM), nitrous oxide inhalation sedation (NOIS), and premedication with Diazepam-for alleviating anxiety during dental treatment, using completed treatment sessions and adverse outcomes as indicators.
Methods And Results: For 239 patients (515 dental records), 18-53 y/o, who underwent dental treatments under anxiety reduction measures, sessions under NOIS were categorized as "nitrous group" (456 sessions) versus premedication with Diazepam or behavioral strategies (control, 59 sessions). Outcomes were completed treatment sessions considering demographic and clinical parameters, and adverse outcomes during and between sessions.
