Cello Repertoire and Performance Practice in Modena under Francesco II d’Este: Giuseppe Colombi, Giovanni Battista Vitali and Domenico Galli

Compared to the attention given to the development of string music in Modena, the development of string music in the nearby city of Bologna in the seventeenth century has always received more focus in musicology. However, the earliest composers who composed solo pieces for cello were instead primarily active in Modena. This study investigates the exchange and development of string music between Modena and Bologna in the mid to late seventeenth century under the leadership of Francesco II d'Este. A critical edition of three compositions for solo cello by Giuseppe Colombi, Giovanni Battista Vitali and Domenico Galli is presented with commentary on the historical background of the period

Overprotection and overcontrol in childhood: An evaluation on reliability and validity of 33-item expanded Childhood Trauma Questionnaire (CTQ-33), Chinese version

Overprotection and overcontrol from parents or other family members, which are not rare in the Chinese culture, have been suggested to be traumatic experiences for some children. However, research on overprotection/overcontrol is much rarer in China compared with other childhood trauma subtypes. One of the possible reasons for this is the lack of easy and feasible screening tools. In this study, we therefore translated and validated a Chinese version of the 33-item Childhood Trauma Questionnaire (CTQ-33), which was expanded from the widely-used 28-item CTQ with an additional overprotection/overcontrol subscale. A total of 248 young healthy participants were recruited and completed the Chinese version of CTQ-33, and 50 of them were retested after an interval of two weeks. At baseline, all participants also completed the 9-item Patient Health Questionnaire and the 7-item Generalized Anxiety Disorder Scale to assess their depression and anxiety, respectively. Our main findings include that: (1) the Chinese version of CTQ-33 showed a good internal consistency (Cronbach\u27s α coefficient = 0.733) and an excellent test-retest reliability over a two-week period (ICC = 0.861); (2) the previously reported significant associations between the overprotection/overcontrol and other subtypes of childhood trauma (abuse and neglect), as well as psychopathological conditions such as depression can all be replicated using the Chinese version of CTQ-33. These results suggest that the Chinese version of CTQ-33 would be a promising tool for assessing various subtypes of childhood adversities, especially the overprotection/overcontrol experiences in Chinese populations

Efficacy and safety of chimeric antigen receptor T cell therapy in relapsed/refractory diffuse large B-cell lymphoma with different HBV status: a retrospective study from a single center

BackgroundChimeric antigen receptor T cell (CAR-T) therapy is an effective salvage treatment in relapsed or refractory(r/r) diffuse large B-cell lymphoma (DLBCL), but the impact of hepatitis B virus (HBV) infection has not been studied.Methods and resultsHere, 51 patients with r/r DLBCL receiving CAR-T therapy were enrolled and analyzed at the First Affiliated Hospital of Soochow University. The overall response rate and the complete remission rate (CR) of CAR-T therapy were 74.5% and 39.2%, respectively. With a median follow-up of 21.1 months after CAR-T, the probabilities of overall survival (OS) and progression-free survival (PFS) at 36 months were 43.4% and 28.7%, respectively. These patients were divided into three cohorts including chronic HBV infection group (n=6), resolved HBV infection group (n=25) and non-HBV infection group (n=20). Bone marrow involvement was significantly higher in the HBV infection group(P<0.001), other basic characteristics before CAR-T therapy were comparable. Subgroup analysis showed that HBV infection status did not affect the efficacy of CAR-T therapy in CR rate, OS or PFS, and there was no significant difference in CAR-T related toxicities between three cohorts. Only one cirrhosis patient with chronic HBV infection experienced HBV reactivation.ConclusionsCAR-T therapy was effective and can be used safely in r/r DLBCL with HBV infection under proper monitoring and antiviral prophylaxis

Conspecific cues that induce spore settlement in the biofouling and green tide-forming alga Ulva tepida provide a potential aggregation mechanism

Abstract(#br)Ulva, an important biofouling and green tide-forming alga, forms aggregations that have adverse economic and ecological impacts. However, little is known regarding the aggregation mechanism of Ulva . Knowledge of Ulva aggregation provides clues for controlling this alga in marine biofouling and green tides. We hypothesized Ulva contains conspecific settlement cue(s). Hexane and dichloromethane extracts of U. tepida fronds were found to induce the settlement of conspecific spores. From these extracts, two bioactive compounds that induce spore settlement in U. tepida were isolated: C16:4 at 5 μg mL −1 and di-n-butyl phthalate at 0.1–10 μg mL −1 . Fatty acids with different carbon chains (C 16 –C 18 ) and degrees of saturation, C16:1 and C18:2, previously reported to be present in U. tepida fronds, showed significant inducing activity for spore settlement. C16:1, C16:4, C18:2, and di-n-butyl phthalate all triggered dense settlements of U. tepida spores. The results support our hypothesis and provide insight into possible aggregation mechanisms for Ulva

Aggregation Pheromone for an Invasive Mussel Consists of a Precise Combination of Three Common Purines

Summary(#br)Most marine benthic invertebrates have a pelagic larval phase, after which they settle preferentially on or near conspecific adults, forming aggregations. Although settlement pheromones from conspecific adults have been implicated as critical drivers of aggregation for more than 30 years, surprisingly few have been unambiguously identified. Here we show that in the invasive dreissenid mussel Mytilopsis sallei (an ecological and economic pest), three common purines (adenosine, inosine, and hypoxanthine) released from adults in a synergistic and precise ratio (1:1.125:3.25) serve as an aggregation pheromone by inducing conspecific larval settlement and metamorphosis. Our results demonstrate that simple common metabolites can function as species-specific pheromones when present in precise combinations. This study provides important insights into our understanding of the ecology and communication processes of invasive organisms and indicates that the combination and ratio of purines might be critical for purine-based signaling systems that are fundamental and widespread in nature

Large-scale Identification of Chemically Induced Mutations in Drosophila melanogaster.

Forward genetic screens using chemical mutagens have been successful in defining the function of thousands of genes in eukaryotic model organisms. The main drawback of this strategy is the time-consuming identification of the molecular lesions causative of the phenotypes of interest. With whole-genome sequencing (WGS), it is now possible to sequence hundreds of strains, but determining which mutations are causative among thousands of polymorphisms remains challenging. We have sequenced 394 mutant strains, generated in a chemical mutagenesis screen, for essential genes on the Drosophila X chromosome and describe strategies to reduce the number of candidate mutations from an average of -3500 to 35 single-nucleotide variants per chromosome. By combining WGS with a rough mapping method based on large duplications, we were able to map 274 (-70%) mutations. We show that these mutations are causative, using small 80-kb duplications that rescue lethality. Hence, our findings demonstrate that combining rough mapping with WGS dramatically expands the toolkit necessary for assigning function to genes
