The crude testicular cells (CTCs) contain many cell types, such as Sertoli cells, leydig cells, spermatogonial stem cells (SSCs), spermatocytes, and other somatic testicular cells, that secrete various growth factors needed in spermatogenesis. The objective of this study was to characterize development of 5-day-old mice testicular cells cultured. Crude testicular cells prepared from the testes of 5-day-old male mice were cultured in Dulbecco's Modified Eagle Medium and incubated at 37°C in a 5% CO2 atmosphere for 6 days. The results demonstrated that the testicular cells developed rapidly with a population doubling time (PDT) of 0.63 days and more than 90% of cells were viable after being cultured for 3 days. The number of Sertoli-like cells increased significantly over days 1, 3, and 6 to 22.1%, 34.6%, and 50.1%, respectively. A significant increase was also observed in fibroblast-like cells (15.5% on day 1 to 28.8% on day 3 and to 26.6% on day 6). In contrast, the number of spermatogonia-like cells decreased significantly (54.3%, 30.4%, and 18.7%, on days 1, 3, and 6, respectively). These data indicated that the developmental pattern of the testicular cell in this study might be affected by the niche provided by the cultured testicular cells. © 2020 Japanese Society of Animal Science.Silicon-containing compounds are widely used as synthetic building blocks, functional materials, or bioactive reagents, and silyl radicals are important intermediates for syntheses and transformations of organosilicons. Here we describe the first protocol for the generation of silyl radicals by photo-induced decarboxylation of silacarboxylic acids, which can be easily prepared in high yield on a gram scale and are very stable to air and moisture. Irradiation of silacarboxylic acids with blue LEDs (455 nm) in the presence of a commercially available photo-catalyst releases silyl radicals, which can further react with various alkenes to give corresponding silylated products in good to high yields with broad functional group compatibility. This reaction proceeds in the presence of water, enabling efficient deuterosilylation of alkenes with D 2 O as the deuterium source. Germyl radicals were similarly obtained. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The influx of sodium (Na+ ) ions into a resting cell is regulated by Na+ channels and by Na+ /H+ and Na+ /Ca2+ exchangers, whereas Na+ ion efflux is mediated by the activity of Na+ /K+ -ATPase to maintain a high transmembrane Na+ ion gradient. Dysfunction of this system leads to changes in the intracellular sodium concentration that promotes cancer metastasis by mediating invasion and migration. In addition, the accumulation of extracellular Na+ ions in cancer due to inflammation contributes to tumor immunogenicity. Thus, alterations in the Na+ ion concentration may potentially be used as a biomarker for malignant tumor diagnosis and prognosis. However, current limitations in detection technology and a complex tumor microenvironment present significant challenges for the in vivo assessment of Na+ concentration in tumor. 23 Na-magnetic resonance imaging (23 Na-MRI) offers a unique opportunity to study the effects of Na+ ion concentration changes in cancer. Although challenged by a low signal-to-noise ratio, the development of ultrahigh magnetic field scanners and specialized sodium acquisition sequences has significantly advanced 23 Na-MRI. 23 Na-MRI provides biochemical information that reflects cell viability, structural integrity, and energy metabolism, and has been shown to reveal rapid treatment response at the molecular level before morphological changes occur. Here we review the basis of 23 Na-MRI technology and discuss its potential as a direct noninvasive in vivo diagnostic and prognostic biomarker for cancer therapy, particularly in cancer immunotherapy. We propose that 23 Na-MRI is a promising method with a wide range of applications in the tumor immuno-microenvironment research field and in cancer immunotherapy monitoring.

The present study aims to comprehensively detect all polymorphisms in the candidate region using whole-genome resequencing data. Based on whole-genome resequencing of eight animals, we detected 127,090 polymorphisms within the region. Of these, 31,945 were located within the genes. We further narrowed the polymorphisms to 6,044 with more than five allele differences between the high and low FAR groups that were located within 179 genes. We subsequently investigated the functions of these genes and selected 170 polymorphisms in eight genes as possible candidate polymorphisms. We focused on SLC27A6 K81M as a putative candidate polymorphism. We genotyped the SNP in a Japanese Black population (n = 904) to investigate the effect on FAR. Analysis of variance revealed that SLC27A6 K81M had a lower p-value (p = .0009) than the most significant SNP in GWAS (p = .0049). Although only SLC27A6 K81M was verified in the present study, subsequent verification of the remaining candidate genes and polymorphisms could lead to the identification of genes and polymorphisms responsible for FAR. © 2020 Japanese Society of Animal Science.The aim of this study was to investigate the effect of different feeding methods on blood biochemical parameters by using a total of 32 Japanese Black breeding cows. The diet (silage) was distributed at a rough estimate for 18 days (FN period), and stanchions were not used in this period. After the FN period, the cows were separated in stanchions for feeding and were fed specified amount of silage by using scales on a feeder wagon, which was determined according to the diet formulation and average body weight of cows, for 30 days (FW period). On the last day of the two experiment periods, the body weight of all cows was recorded and blood samples were collected from 10 randomly selected cows. β-hydroxybutyric acid and albumin (Alb) levels were significantly higher after the FW period than after FN period. The variation of glucose, Alb, calcium and lactic acid was significantly smaller after the FW period. Several blood parameters of the FW period were approximately the appropriate range of a Japanese Black breeding herd in the dry period.
