TL;DR: It is demonstrated that some acute effects and motivational responses elicited by nicotine can be modulated by the endogenous cannabinoid system and support the existence of a physiological interaction between these two systems.

Abstract: The simple translation of a questionnaire may lead to misinterpretation due to language and cultural differences. When using questionnaires developed in other countries and languages in scientific studies it is necessary, besides the translation, to carry out a cross-cultural adaptation and validation. Our objective was to review the literature on cross-cultural adaptation and validation (CCAV) of health questionnaires, and to synthesize and propose recommendations based on the scientific literature to facilitate this process. The CCAV should follow a systematic process. Two steps are recommended: 1) cross-cultural adaptation: direct translation, synthesis, back translation, expert committee consolidation and pre-testing, and 2) validation (with up to seven steps): assessment of internal consistency, reliability, intra- and inter-observer reliability, face, content, criterion and construct validity. Lack of equivalence between questionnaires limits the comparability of results among populations with different cultures and languages and the exchange of information in the scientific community.

TL;DR: In this paper, the authors explored Δ9-tetrahydrocannabinol (THC) activity in mice lacking μ-, δ- or κ-opioid receptor genes.
Abstract: Repeated THC administration produces motivational and somatic adaptive changes leading to dependence in rodents. To investigate the molecular basis for cannabinoid dependence and its possible relationship with the endogenous opioid system, we explored Δ9-tetrahydrocannabinol (THC) activity in mice lacking μ-, δ- or κ-opioid receptor genes. Acute THC-induced hypothermia, antinociception, and hypolocomotion remained unaffected in these mice, whereas THC tolerance and withdrawal were minimally modified in mutant animals. In contrast, profound phenotypic changes are observed in several place conditioning protocols that reveal both THC rewarding and aversive properties. Absence of μ receptors abolishes THC place preference. Deletion of κ receptors ablates THC place aversion and furthermore unmasks THC place preference. Thus, an opposing activity of μ- and κ-opioid receptors in modulating reward pathways forms the basis for the dual euphoric–dysphoric activity of THC.

TL;DR: Somatic TERT promoter mutations are an early, highly prevalent genetic event in UBC and are not associated with TERT mRNA levels or disease outcomes, and a SNaPshot assay in urine may help to detect UBC recurrences.

TL;DR: This study overturns prior notions of the taxon's evolutionary history, as many long-recognized subfamilies and tribes are para- or polyphyletic, and provides a much-needed backbone for a revised classification of butterflies and for future comparative studies including genome evolution and ecology.
