l.Testicular tumors are rare in the prepubertal population and often are germ cell tumors. Myofibroma is a rare spindle cell neoplasm composed of myofibroblasts, which are intermediate cells between fibroblasts and smooth muscle cells. Only two prepubertal testicular myofibromas have been previously reported. While cryptorchidism is a risk factor for testicular germ cell tumors, the exact etiology of testicular myofibroma is unknown. We report a case of testicular myofibroma in a six-year-old male with a history of undescended testes, as well as a review of the literature. read more This case suggests a possible connection between undescended testes and testicular myofibroma.Clinical utility of cisplatin based neoadjuvant chemotherapy (NAC) prior to radical cystectomy is limited because of lack of tools that can guide for a better patient selection. We aim to explore if a combination of biomarkers is superior to a single marker. Pretreatment tumor specimens and clinical data from two randomized trials including 250 patients with T2-T4 urothelial bladder cancer, were used. The information on the expressions on tumor tissue of four biomarkers; CCTα, emmprin, survivin, and BCL-2, detected by immunohistochemistry in our previous studies, was used. Cox proportional hazard models, including treatment-by-biomarker interaction terms, were used to assess the predictive value of the biomarkers for efficacy of NAC on overall survival. CCTα provided predictive information about the efficacy of NAC (interaction P=0.009). None of the other biomarkers provided statistically significant information additional to CCTα. The adjusted hazard ratio for NAC treated versus no-NAC was 0.42 (95% CI 0.27-0.64) for patients with negative CCTα expression, when adding information about emmprin it decreased to 0.33 (95% CI 0.19-0.56) for patients with both negative CCTα and emmprin. This corresponds to a decrease in number needed to treat from 4 to 3 patients. The combination of CCTα with survivin or BCL-2 yielded similar results. In a group of patients with muscle invasive bladder cancer a combination of two biomarkers might improve the possibility to identify patients most likely to benefit from the use of NAC. Further studies designed to have sufficient power to detect an interaction effect are needed.T-box transcription factor 3 (TBX3) gene encodes a transcriptional suppressor and plays an important role in embryonic development, which belongs to the T-box family. TBX3 also has been found to be associated with body size traits in horse that is a relative of donkey. Therefore, TBX3 is considered as a promising candidate gene for economic traits of donkey. This study aimed to reveal the significant variation of TBX3 gene in Dezhou donkey and explores the relationship between genotypes and body sizes. In this study, an A > G mutation was found in the intron 2 of TBX3 gene by sequencing, and three genotypes (AA, GG and AG) were identified in 380 Dezhou donkey individuals with Tm-shift method. Association analysis illustrated that there were significant differences between AA and GG genotype in body length, body height, chest depth, chest circumference, body weight, hucklebone width and rump length. Our results demonstrated that the polymorphism of TBX3 is significantly associated with body size traits, which can serve as a marker to improve donkey production performance.The SARS-CoV-2 Variant of Concern 202012/01 (VOC-202012/01) is rapidly spreading worldwide owing to its substantial transmission advantage. The variant has changes in critical sites of the spike protein with potential biological significance. Moreover, VOC-202012/01 has a mutation that inactivates the ORF8 protein, whose absence can change the clinical features of the infection. Why VOC-202012/01 is more transmissible remains unclear, but spike mutations and ORF8 inactivation stand out by their known phenotypic effects. Here I show that variants combining relevant spike mutations and the absence of ORF8 occurred in SARS-CoV-2 and related viruses circulating in other host species. A truncated ORF8 (Q23stop) occurred in a SARS-CoV-2-related virus from a pangolin seized in China in 2017, also with several mutations in critical spike sites. Strikingly, I found that variants without ORF8 (E19stop) and with the N501T spike mutation circulated in farmed mink and humans from Denmark. Although with differences to VOC-202012/01, the identification of these variants highlights the danger of having reservoirs of SARS-CoV-2 and related viruses where more transmissible variants may occur and spill over to humans.
Obesity and metabolic syndrome frequently co-exist and define obese individuals into different obesity phenotypes, such as metabolically healthy obese (MHO), metabolically unhealthy obese (MUO) and metabolically unhealthy normal weight (MUNW). Growing evidence suggests that genetic predisposition and environmental factors can explain the heterogeneity among these phenotypes.

We conducted a case-control study including 130 MHO, 251 MUNW, 208 MUO and 336 health controls by genotyping 2 SNPs (rs2241766, rs1501299) in ADIPOQ to investigate possible associations between SNPs in the ADIPOQ gene with susceptibility to three obese phenotypes respectively in Chinese Han population. Unconditional logistic regressions were used to detect the association between ADIPOQ SNPs and MHO/MUNW/MUO risks.

Variant G allele of rs2241766 was associated with a reduced odds of MUO (additive model Adjusted OR=0.55; 95% CI=0.40-0.75; P<0.001) and no evidence of any significant association between rs2241766 and MHO phenotype (additive model Adjusted OR=0.84; 95% CI=0.61-1.16; P=0.306) or MUNW phenotype (additive model Adjusted OR=0.95; 95% CI=0.73-1.24; P=0.720) was found. Minor allele T of rs1501299 were significantly associated with decreased risk of MHO (Adjusted OR=0.53; 95% CI=0.37-0.76; P<0.001) and MUNW (Adjusted OR=0.63; 95% CI=0.48-0.83; P=0.001) in additive genetic model after correction for multiple testing.

The variant G allele of rs2241766 was negatively associated with risk of MUO and variant T allele of rs1501299 exhibited reduced odds for MHO and MUNW. Beyond that, future studies are warranted to validate and extend our findings.
