DICER1 germline mutations cause DICER1 syndrome, in which multinodular goiter is a common feature. Recently, somatic DICER1 mutations have been reported in sporadic thyroid carcinomas, of which the newly described macro-follicular variant of follicular thyroid carcinoma (MV-FTC) seems particularly enriched for this aberrancy. We here report histological and genetic findings in five follicular thyroid tumors with macrofollicular architecture (four carcinomas and one adenoma).

We have diagnosed five cases during a year-long period at the Karolinska University Hospital, a tertiary thyroid cancer center with a catchment area of approximately 2.3 million inhabitants. Tumor DNA was interrogated using a commercially available massive parallel sequencing platform. All cases were female patients ranging from 13-33 years at surgery. A single patient was a DICER1 syndrome carrier; the others were sporadic cases. All tumors displayed a macrofollicular architecture with a broad capsule. The MV-FTCs displayed capsular
Measuring food-related quality of life (FRQoL) quantifies the psychosocial impact of eating and drinking. FRQoL and associated factors are not well explored in people with inflammatory bowel disease (IBD), despite IBD being a chronic disease affecting the digestive tract. The present study aimed to characterise and identify any patient or disease-related predictors of FRQoL in individuals with IBD.

Adults with a formal diagnosis of IBD were recruited to a prospective multicentre cross-sectional study between April 2018 and December 2019. Participants completed questionnaires measuring FRQoL (FRQoL-29), clinical disease activity (Harvey Bradshaw Index and Simple Clinical Colitis Activity Index), restrictive eating behaviour (Nine-Item Avoidant/Restrictive Food Intake Disorder Screen), mental health (Depression Anxiety Stress Scale-21) and other patient and disease-related variables. A multivariable regression was performed to identify factors associated with FRQoL.

One hundred and eight participants compFRQoL in people with IBD is poorer in those with restrictive eating behaviours and clinically active disease. Interestingly, it was greater in those with previous IBD surgery. Further research is required to validate these associations and explore longitudinal effects of poor FRQoL on patient outcomes and potential strategies for prevention or management of impaired FRQoL in IBD.Development and maintenance of diverse organ systems require context-specific regulation of stem cell behaviour. We hypothesize that this is achieved via reciprocal regulation between the cell cycle machinery and differentiation factors. This idea is supported by the parallel evolutionary emergence of differentiation pathways, cell cycle components and complex multicellularity. In addition, the activities of different cell cycle phases have been found to bias cells towards stem cell maintenance or differentiation. Finally, several direct mechanistic links between these two processes have been established. Here, we focus on interactions between cyclin-CDK complexes and differentiation regulators of the Notch pathway and Sox family of transcription factors within the context of pluripotent and neural stem cells. Thus, this hypothesis formalizes the links between these two processes as an integrated network. Since such factors are common to all stem cells, better understanding their interconnections will help to explain their behaviour in health and disease.A novel virus, severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19) worldwide appeared in 2019. BMS-502 mouse Detailed scientific knowledge of the members of the Coronaviridae family, including the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is currently lacking. Structural studies of the MERS-CoV proteins in the current literature are extremely limited. We present here detailed characterization of the structural properties of MERS-CoV macro domain in aqueous solution. Additionally, we studied the impacts of chosen force field parameters and parallel tempering simulation techniques on the predicted structural properties of MERS-CoV macro domain in aqueous solution. For this purpose, we conducted extensive Hamiltonian-replica exchange molecular dynamics simulations and Temperature-replica exchange molecular dynamics simulations using the CHARMM36m and AMBER99SB parameters for the macro domain. This study shows that the predicted secondary structure properties including their propensities depend on the chosen simulation technique and force field parameter. We perform structural clustering based on the radius of gyration and end-to-end distance of MERS-CoV macro domain in aqueous solution. We also report and analyze the residue-level intrinsic disorder features, flexibility and secondary structure. Furthermore, we study the propensities of this macro domain for protein-protein interactions and for the RNA and DNA binding. Overall, results are in agreement with available nuclear magnetic resonance spectroscopy findings and present more detailed insights into the structural properties of MERS CoV macro domain in aqueous solution. All in all, we present the structural properties of the aqueous MERS-CoV macro domain using different parallel tempering simulation techniques, force field parameters and bioinformatics tools.Maintaining Na+ /K+ homeostasis is a critical feature for plant survival under salt stress, which depends on the operation of Na+ and K+ transporters. Although some K+ transporters mediating root K+ uptake have been reported to be essential to the maintenance of Na+ /K+ homeostasis, the effect of K+ long-distance translocation via phloem on plant salt tolerance remains unclear. Here, we provide physiological and genetic evidence of the involvement of phloem-localized OsAKT2 in rice salt tolerance. OsAKT2 is a K+ channel permeable to K+ but not to Na+ . Under salt stress, a T-DNA knock-out mutant, osakt2 and two CRISPR lines showed a more sensitive phenotype and higher Na+ accumulation than wild type. They also contained more K+ in shoots but less K+ in roots, showing higher Na+ /K+ ratios. Disruption of OsAKT2 decreases K+ concentration in phloem sap and inhibits shoot-to-root redistribution of K+ . In addition, OsAKT2 also regulates the translocation of K+ and sucrose from old leaves to young leaves, and affects grain shape and yield.
