PA and its modified phospholipids travel between organelle membranes, for example, the endoplasmic reticulum (ER) and mitochondrial inner membrane, to be converted to the other phospholipids. To gain insight into mechanisms of the phospholipid biosynthetic pathways, we searched for factors whose loss affects the phospholipid synthesis using an in vitro phospholipid transport assay. Among the various factors that were tested, we noticed that a lack of Pah1, which is a phosphatidic acid phosphatase, led to severe defects in phospholipid synthesis, which was not rescued by re-expression of wild-type Pah1. These results indicated other mutations in addition to the deletion of Pah1. Interestingly, we found that stress conditions associated with the yeast transformation process triggered a disruption of the INO4 gene by insertion of the Ty1 retrotransposon in pah1∆ strains. Additionally, we noticed that loss of the diacylglycerol kinase Dgk1, which has an opposing function to Pah1, suppressed the insertional mutation of INO4. These findings suggest that normal Pah1 function is critical for the suppression of insertional mutations by retrotransposon elements. © 2020 Federation of American Societies for Experimental Biology.On-demand motion of highly swollen polymer systems can be triggered by changes in pH, ion concentrations, or by heat. Here, shape-programmable, architectured hydrogels are introduced, which respond to ultrasonic-cavitation-based mechanical forces (CMF) by directed macroscopic movements. The concept is the implementation and sequential coupling of multiple functions (swellability in water, sensitivity to ultrasound, shape programmability, and shape-memory) in a semi-interpenetrating polymer network (s-IPN). The semi-IPN-based hydrogels are designed to function through rhodium coordination (Rh-s-IPNH). These coordination bonds act as temporary crosslinks. The porous hydrogels with coordination bonds (degree of swelling from 300 ± 10 to 680 ± 60) exhibit tensile strength σmax up to 250 ± 60 kPa. Shape fixity ratios up to 90% and shape recovery ratios up to 94% are reached. Potential applications are switches or mechanosensors. © 2020 Helmholtz-Zentrum Geestacht.

These range from twofold and fourfold degenerate Weyl and Dirac points, respectively, to sixfold and eightfold degenerate points that are predicted to give rise, under modest magnetic fields or strain, to topological semimetallic behaviors. The present study shows that the nonsymmorphic compound PdSb2 hosts six-component fermions or sextuplets. Using angle-resolved photoemission spectroscopy, crossing points formed by three twofold degenerate parabolic bands are directly observed at the corner of the Brillouin zone. The group theory analysis proves that under weak spin-orbit interaction, a band inversion occurs. © 2020 The Authors. Published by WILEY-VCH Verlag GmbH & Co.

The FOXP3 gene polymorphisms, the rs2232365 A/G and the rs3761548 A/C, were identified to be associated with regulatory T cell-mediated immunosuppression. The response to HBV infection may be affected by FOXP3 polymorphisms. The present study aimed to assess the relationship between FOXP3 gene polymorphisms and chronic HBV infection risk. METHODS FOXP3 gene polymorphisms were explored in 237 chronic HBV patients and in 237 individuals with HBV spontaneous clearance using a real-time polymerase chain reaction. RESULTS The patients with rs2232365 AG and rs3761548 AC genotype had a 1.20- and a 1.58-fold greater HBV risk than non-carriers patients, although they were not significant. Moreover, the AA genotypes of both polymorphisms in the males and females had an increased the persistent HBV risk, although this also was not statistically significant. CONCLUSIONS In conclusion, the present study is the first report to demonstrate that these polymorphisms have no effect on the risk of chronic HBV infection. This results suggest that FOXP3 gene polymorphisms and FOXP3 expression should be evaluated together with frequency of regulatory T cells in HBV infection. © 2020 John Wiley & Sons, Ltd.OBJECTIVES To determine the association between hormone therapy and outcomes in a cohort of prostate cancer patients with a family history of prostate cancer. METHODS Data of patients with prostate cancer who had received hormone therapy were extracted from a nationwide community-based database established by the Japan Study Group for Prostate Cancer. Family history of prostate cancer was available for 13 346 of these patients, who thus comprised the study cohort. Prognostic variables, including progression-free survival, cancer-specific survival and overall survival, were compared between men with familial and men with sporadic prostate cancer. RESULTS A positive family history was identified in 220 patients (1.6%). Patients with a positive family history were younger than those without; however, other clinicopathological characteristics and prognoses were comparable. In subgroup analysis, family history was identified as a possible favorable prognostic factor for overall survival among patients with a prostate-specific antigen level at diagnosis less then 100 ng/mL and those with low or intermediate Japan Cancer of the Prostate Risk Assessment. CONCLUSIONS Our findings show that familial prostate cancer has an early-onset feature or is diagnosed earlier than sporadic prostate cancer. However, the prognosis of individuals with familial prostate cancer undergoing hormone therapy is comparable to those with sporadic prostate cancer. © 2020 The Japanese Urological Association.
