Precision oncology, despite achieving identifying the putative origin of the CUP, so far failed to globally improve outcomes of patients. Targeting molecular pathways based on molecular analysis in CUP management is under investigation. Immunotherapy has not shown ground-breaking results, to date. Accrual is also a crucial issue in CUP trials. Herein we review CUP history, biological features and remaining questions in CUP biology, the two main approaches of molecular oncology in CUP management, in order to draw perspectives in the enormous challenge of improving CUP patient outcomes.
Initiation of e-cigarette use by young adults is a significant public health issue within the debate on vaping. The current study is an exploratory evaluation of brief educational information among young adults and investigated outcomes as a function of JUUL use and smoking status.

Participants (N=947) were young adults (<30years old) recruited from Amazon's Mechanical Turk based on smoking and JUUL use status. Participants completed baseline assessments, viewed a brief JUUL educational handout, and completed post-assessments.

There was a significant TimeXGroup interaction for JUUL-related knowledge (p<.001), with never JUUL/never smokers showing the greatest increase in knowledge. Brief education increased JUUL-related knowledge and risk perceptions and had a modest impact on commitment to quitting and readiness to quit JUUL (all p≤0.001; ds=0.06-0.74; time×group p>.05 for all contrasts except JUUL-related knowledge). Participants showed modest decreases in interest in future JUUL use, interessuggest current JUUL use status is more important in informing JUUL-related attitudes than smoking status.Most published studies, regarding students' participation in drinking games (DGs), originate from the United States of America (USA). This study extends research to the United Kingdom (UK) and countries of mainland Europe. University students from five countries completed an anonymous online questionnaire which included measures of the frequency of DG participation, along with types, contexts and motives for participation. Responses are compared by the gender, and country of domicile of the participants. The study is based on the results of the questionnaire administered to 306 Social Work students from five universities/countries of which 72.2% are females, with a mean age of 22.6 years. This included students in Austria, Germany, the Netherlands, the UK and the USA. A high proportion of students, irrespective of gender, or country of domicile, stated that they participated in DGs. To 'meet people' and 'to get drunk' are the most important reasons stated for DG participation. Less benign motives, to 'control others' or 'get other people drunk', are reported as 'not important'. The most common types of DGs were consumption and team DGs. The pre-partying involved in DGs and associated consequences show important targets in alcohol harm minimization interventions. Harm minimization/public health messages regarding safer drinking need to recognize that younger students often feel they are immortal and do not fully appreciate risks and adverse effects of DGs and drink to have fun and be sociable.
This study examined the associations between alcohol-related cognitions within the social reaction pathway of the Prototype Willingness Model and concurrent (use of two or more substances within a specified time period) use of 1) alcohol and marijuana and 2) alcohol and prescription stimulant misuse.

A convenience sample of 1,062 emerging adults in the U.S. (18-20years old; 54.5% female) who reported past 3-month alcohol use completed a baseline survey as part of a larger randomized controlled trial.

Results indicate that controlling for age, biological sex, race, ethnicity, and college enrollment, perceived descriptive norms and willingness to drink were associated with past 3-month concurrent alcohol and marijuana use and concurrent alcohol and prescription stimulant misuse. However, alcohol prototype similarity and alcohol-related perceived vulnerability were not associated with either concurrent use outcome examined.

These findings suggest that alcohol-related perceived descriptive norms and willingness to drink are associated with concurrent substance use among young adults. Thus, it is possible that existing efficacious alcohol interventions that target descriptive norms and willingness to drink may have the added benefit of also reducing concurrent substance cognitions and ultimately use.

Exposure to chronic constant light (CCL) has been reported to impair cognition, yet whether the underlying mechanism involves m6A remains unknown. In this study, mice exposed to CCL for 3 weeks show impaired cognitive behavior, which was associated with increased m6A level in hippocampus. Accordingly, the m6A demethylase FTO was inhibited while the methyltransferases METTL3, METTL14 and WTAP, as well as the reader protein YTHDF2, were elevated in the hippocampus of CCL-exposed mice. CCL exposure significantly activated hippocampal expression of circadian regulator cryptochrome 1 and 2 (CRY1 and 2). Meanwhile, hippocampal neurogenesis was impaired with suppression of BDNF/TrκB/ERK pathway. To further delineate the signaling pathway and the role of m6A, we altered the expression of CRY1/2 in hippocampus neuron cells. CRY1/2 overexpression inhibited FTO and increased m6A levels, while CRY1/2 knockdown led to opposite results. Luciferase reporter analysis further confirmed CRY1/2-induced FTO suppression. Furthermore, FTO knockdown increased m6A on 3'UTR of TrκB mRNA, and decreased TrκB mRNA stability and TrκB protein expression, in a YTHDF2-dependent manner. These results indicate that CCL-activated CRY1/2 causes transcriptional inhibition of FTO, which suppresses TrκB expression in hippocampus via m6A-dependent post-transcriptional regulation and contributes to impaired cognitive behavior in mice exposed to constant light.Maintaining the safety and quality of food are major concerns while developing biomaterial based food packaging. It offers a longer shelf-life as well as protection and quality control to the food based on international standards. Nano-biotechnology contributes to a far extent to make advanced packaging by developing multifunctional biomaterials for potential applications providing smarter materials to consumers. Applications of nano-biocomposites may thus help to deliver enhanced barrier, mechanical strength, antimicrobial and antioxidant properties to novel food packaging materials. Starch derived bioplastics, polylactic acid and polyhydroxybutyrate are examples of active bioplastics currently in the food packaging sector. This review discusses the various types of biomaterials that could be used to improve future smarter food packaging, as well as biomaterials' potential applications as food stabilizers, pathogen control agents, sensors, and edible packaging materials. The regulatory concerns related to the use of biomaterials in food packaging and commercially available biomaterials in different fields are also discussed. Development of novel biomaterials for different food packaging applications can therefore guarantee active food packaging in future.Perfluorobutane sulfonate (PFBS), an emerging pollutant, is associated with disruption of placental functions and adverse birth outcomes. However, the precise mechanism of this disruption remains unclear. Extravillous trophoblasts make up the majority of cells in the placenta, and have invasive abilities, which plays a critical role in a successful pregnancy. It has been reported that inducible nitric oxide (iNOS) and nitric oxide (NO) signaling is associated with trophoblast migration and invasion. In this study, PFBS exposure was found to enhance trophoblast invasion and increase matrix metalloproteinase 9 (MMP-9) levels. Additionally, PFBS upregulated iNOS levels and stimulated NO generation. iNOS inhibitor treatment attenuated the increased invasion of trophoblasts and MMP-9 expression induced by PFBS. learn more Extracellular signal-regulated kinase (ERK) phosphorylation was also enhanced by PFBS exposure. In the presence of an ERK pathway inhibitor, however, the increases in trophoblast invasion, the induction of NO production, iNOS expression and MMP-9 expression induced by PFBS were attenuated. Taken together, these results suggest that iNOS/NO signaling is triggered by activation of the ERK signaling pathway, and that iNOS/NO signaling mediates PFBS-induced stimulation of trophoblast invasion.Moxidectin is an antiparasitic drug belonging to the class of the macrocyclic lactones, subgroup mylbemicins. It is used worldwide in veterinary practice, but little is known about its potential environmental risks. Thus, we used the zebrafish embryo as a model system to study the potential effects of moxidectin on aquatic non-target organisms. The analyses were performed in two experimental sets (1) acute toxicity and apical endpoints were characterized, with biomarker assays providing information on the activity levels of catalase (CAT), glutathione S-transferase (GST), lactate dehydrogenase (LDH), and acetylcholinesterase (AChE); and (2) internal concentration and spatial distribution of moxidectin were determined using ultraperformance liquid chromatography quadrupole-time-of-flight mass spectrometry (UPLC-QToF-MS) and matrix-assisted laser desorption/ionization-MS imaging (MALDI-MSi). The acute toxicity to zebrafish embryos (96 hpf) appeared mainly as a decrease in hatching rates (EC50 = 20.75 μg/L). It also altered the enzymatic activity of biomarker enzymes related to xenobiotic processing, anaerobic metabolism, and oxidative stress (GST, LDH, and CAT, respectively) and strongly accumulated in the embryos, as internal concentrations were 4 orders of magnitude higher than those detected in exposure solutions. MALDI-MSi revealed accumulations of the drug mainly in the head and eyes of the embryos (72 and 96 hpf). Thus, our results show that exposure to moxidectin decreases hatching success by 96 h and alters biochemical parameters in the early life stages of zebrafish while accumulating in the head and eye regions of the animals, demonstrating the need to prioritize this compound for environmental studies.1-Nitropyrene (1-NP) is one component of atmospheric fine particles. Previous report revealed that acute 1-NP exposure induced respiratory inflammation. This study aimed to investigate whether chronic 1-NP exposure induces pulmonary fibrosis. Male C57BL6/J mice were intratracheally instilled to 1-NP (20 μg/mouse/week) for 6 weeks. Diffuse interstitial inflammation, a-smooth muscle actin (a-SMA)-positive cells, a marker of epithelial-mesenchymal transition (EMT), and an extensive collagen deposition, measured by Masson staining, were observed in 1-NP-exposed mouse lungs. Pulmonary function showed that lung dynamic compliance (Cydn-min) was reduced in 1-NP-exposed mice. Conversely, inspiratory resistance (Ri) and expiratory resistance (Re) were elevated in 1-NP-exposed mice. Mechanistically, cell migration and invasion were accelerated in 1-NP-exposed pulmonary epithelial cells. In addition, E-cadherin, an epithelial marker, was downregulated, and vimentin, a-SMA and N-cadherin, three mesenchymal markers, were upregulated in 1-NP-exposed pulmonary epithelial cells.
