Microwave drying was found to be the optimum choice for drying apples.As an endpoint of community response to contaminants, average periodic density of populations (APDP) has been introduced to model species interactions in a community with 4 planktonic species. An ecological model for the community was developed by means of interspecific relationship including competition and predation to calculate the APDP. As a case study, we reported here the ecotoxicological effects of petroleum hydrocarbons (PHC) collected from Bohai oil field on densities of two algae, Platymonas subcordiformis and Isochrysis galbana, a rotifer, Brachionus plicatilis, and of a cladocera, Penilia avirostris, in single species and a microcosm experiment. Time scales expressing toxic effect increased with increasing levels of toxic effect from molecule to community. Remarkable periodic changes in densities were found during the tests in microcosm experiment, revealing a strong species reaction. The minimum time scale characterizing toxic effect at a community level should be the common cycle of population densities of the microcosm. In addition, the cycles of plankton densities shortened in general with increasing PHC, showing an evident toxic effect on the microcosm. Using APDP as the endpoint, a threshold concentration for the modeled microcosm was calculated to be 0.404 mg-PHC L-1. The APDP was found to be more sensitive and reliable than the standing crops of populations as the endpoint. This indicated that the APDP, an endpoint at the community level, could be quantitatively related to the endpoints at the population level, and led to the quantitative concentration-toxic effect relationship at the community level.Microcystis aeruginosa (MA) is a primary hazardous cyanobacteria species in aquatic ecosystems that can produce microcystin-LR (MC-LR), which harms aquatic animals. The intestine is an important target tissue for MA and MC-LR. In this study, we investigated the effects of MA and MC-LR exposure on the intestinal microbiota variation and immune responses of Litopenaeus vannamei. Shrimp were experimentally exposed to MA and MC-LR for 72 h. The results showed that both MA and MC-LR exposure caused marked histological variation and apoptosis characteristics and increased oxidative stress in the intestine. Furthermore, the relative expression levels of antimicrobial peptide genes (ALF, Crus, Pen-3) decreased, while those of pro-inflammatory cytokines (MyD88, Rel, TNF-a), a pattern-recognition receptor (TLR4) and a mediator of apoptosis (Casp-3) increased. MA and MC-LR exposure also caused intestinal microbiota variation, including decreasing microbial diversity and disturbing microbial composition. Specifically, the relative abundance of Proteobacteria decreased in the two stress groups; that of Bacteroidetes decreased in the MA group but increased in the MC-LR group, while Tenericutes varied inversely with Bacteroidetes. Our results indicate that MA and MC-LR exposure causes intestinal histopathological and microbiota variations and induces oxidative stress and immune responses in L. vannamei. In conclusion, this study reveals the negative effects of MA and MC-LR on the intestinal health of shrimp, which should be considered in aquaculture.Italy is among the most severely hit nations in terms of hospital patients’ overload, and its healthcare workforce is struggling to cope with challenges that could threaten their own wellbeing. In this scenario, understanding the health-related consequences of COVID-19 outbreak on Italian frontline healthcare professionals is urgent. Our study provides a first account of the huge psycho-physical impact of COVID-19 outbreak for healthcare workers in Italy. PP1 manufacturer Italian healthcare professionals reported relevant work-related psychological pressure, emotional burnout and somatic symptoms. This result requires attention as previous studies showed that emotional distress is associated with long-lasting effect on professionals’ health, including risk of post-traumatic stress disorder.We examined narrative identity as a possible transdiagnostic marker of psychopathology by interviewing individuals with schizophrenia, individuals with depression and a nonclinical control group about past and future chapters in their life stories. Participants were 20 patients with schizophrenia, 20 patients with depression, and 20 nonclinical control participants matched on age, gender, and education. Participants described up to 10 chapters in their past and future life stories and self-rated chapters on emotional tone and self-event connections. In addition, cognitive function and current levels of symptoms was assessed. Both patient groups self-rated their past chapters as more negative and less positive compared to the control group, but did not differ from each other. There were no group differences in positivity of future chapters, but both patient groups identified fewer future chapters with shorter temporal projections. The results are consistent with the notion that negative past aspects of narrative identity are a transdiagnostic marker of psychopathology, while also suggesting that individuals with mental illness construct a positive future, which may support hope.Cognitive forms of Theory of Mind (ToM) have been linked to social function in Bipolar Disorder (BD). To explore this social functioning was assessed with the GAF and cognitive ToM was assessed with the Hinting Task and the Picture Sequencing Task (PST) in 45 patients with BP and 45 healthy controls. As predicted, the BD group took longer to complete the PST. The BD group did not offer more incorrect responses to either cognitive ToM task. Greater latency on the PST predicted poorer social function after controlling for symptoms, partially supporting a relationship between ToM and social function in BD.Pharmacogenomic tests used to guide clinical treatment for major depressive disorder (MDD) must be thoroughly validated. One important assessment of validity is the ability to predict medication blood levels, which reflect altered metabolism. Historically, the metabolic impact of individual genes has been evaluated; however, we now know that multiple genes are often involved in medication metabolism. Here, we evaluated the ability of individual pharmacokinetic genes (CYP2C19, CYP2D6, CYP3A4) and a combinatorial pharmacogenomic test (GeneSight Psychotropic®; weighted assessment of all three genes) to predict citalopram/escitalopram blood levels in patients with MDD. Patients from the Genomics Used to Improve DEpression Decisions (GUIDED) trial who were taking citalopram/escitalopram at screening and had available blood level data were included (N=191). In multivariate analysis of the individual genes and combinatorial pharmacogenomic test separately (adjusted for age, smoking status), the F statistic for the combinatorial pharmacogenomic test was 1.
