We report a rare case of localized prostate cancer with BRCA2 and RB1 co-loss, which is usually found at a more advanced stage with a poor prognosis. A 59-year-old male with prostate cancer was referred to our hospital for surgical treatment. He had schizophrenia that was well controlled by medicine. He had no family history of prostate cancer, breast cancer, or ovarian cancer. His initial PSA was 4.5 ng/mL, and Gleason score 3 + 4 adenocarcinoma was detected in one of 12 needle biopsy cores. Imaging studies demonstrated the clinical stage to be cT2aN0M0. Therefore, robot-assisted laparoscopic radical prostatectomy (RALP) with bilateral nerve sparing was performed. Based on histopathological analysis, the Gleason score was 4 + 3 and the pathological stage was pT2N0M0 with a negative surgical margin. Genetic sequencing identified BRCA2 and RB1 co-loss with limited loss of heterogeneity (LOH). At 12 months after surgery, his PSA level remained The online version contains supplementary material available at 10.1007/s13691-021-00469-z.

Magnetic resonance imaging revealed a multilocular cystic component with papillary lesions in the background of endometriosis, suggesting a seromucinous borderline tumor or ovarian cancer. A right salpingo-oophorectomy and partial omentectomy were performed at 7 weeks of gestation. Pathological examination demonstrated a serous borderline tumor. The subsequent pregnancy course was uneventful, and she gave birth to a healthy baby at 39 weeks of gestation. She wanted to retain fertility, and close follow-up was performed. Four years later, she became pregnant, and a lesion suggesting recurrence in the left ovary was detected. An abdominal left ovarian cystectomy was performed at 13 weeks of gestation, which demonstrated recurrence of the serous borderline tumor. She gave birth to a healthy baby at 39 weeks of gestation. Two months after delivery, she underwent total abdominal hysterectomy with left salpingo-oophorectomy, which revealed no malignant findings. We also reviewed 10 reports that included 58 cases of borderline ovarian tumors diagnosed during pregnancy. The borderline ovarian tumors diagnosed during pregnancy exhibited different characteristics according to each subtype, suggesting the importance of diagnosing borderline ovarian tumor subtypes preoperatively.In epidemiology, the effective reproduction number R e is used to characterize the growth rate of an epidemic outbreak. If R e > 1 , the epidemic worsens, and if R e less then 1 , then it subsides and eventually dies out. In this paper, we investigate properties of R e for a modified SEIR model of COVID-19 in the city of Houston, TX USA, in which the population is divided into low-risk and high-risk subpopulations. The response of R e to two types of control measures (testing and distancing) applied to the two different subpopulations is characterized. A nonlinear cost model is used for control measures, to include the effects of diminishing returns. Lowest-cost control combinations for reducing instantaneous R e to a given value are computed. We propose three types of heuristic strategies for mitigating COVID-19 that are targeted at reducing R e , and we exhibit the tradeoffs between strategy implementation costs and number of deaths. We also consider two variants of each type of strategy basic strategies, which consider only the effects of controls on R e , without regard to subpopulation; and high-risk prioritizing strategies, which maximize control of the high-risk subpopulation. Results showed that of the three heuristic strategy types, the most cost-effective involved setting a target value for R e and applying sufficient controls to attain that target value. This heuristic led to strategies that begin with strict distancing of the entire population, later followed by increased testing. Strategies that maximize control on high-risk individuals were less cost-effective than basic strategies that emphasize reduction of the rate of spreading of the disease. The model shows that delaying the start of control measures past a certain point greatly worsens strategy outcomes. We conclude that the effective reproduction can be a valuable real-time indicator in determining cost-effective control strategies.Recent COVID-19 pandemic situation caused due to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affected global health as well as economics. There is global attention on prevention, diagnosis as well as treatment of COVID-19 infection which would help in easing the current situation. The use of nanotechnology and nanomedicine has been considered to be promising due to its excellent potential in managing various medical issues such as viruses which is a major threat. Nanoparticles have shown great potential in various biomedical applications and can prove to be of great use in antiviral therapy, especially over other conventional antiviral agents. This review focusses on the pathophysiology of SARS-CoV-2 and the progression of the COVID-19 disease followed by currently available treatments for the same. Use of nanotechnology has been elaborated by exploiting various nanoparticles like metal and metal oxide nanoparticles, carbon-based nanoparticles, quantum dots, polymeric nanoparticles as well as lipid-based nanoparticles along with its mechanism of action against viruses which can prove to be beneficial in COVID-19 therapeutics. However, it needs to be considered that use of these nanotechnology-based approaches in COVID-19 therapeutics only aids the human immunity in fighting the infection. The main function is performed by the immune system in combatting any infection.Waterlogging is a severe abiotic stressor that inhibits crop growth and productivity owing to the decline in the amount of oxygen available to the waterlogged organs. Although melon (Cucumis melo L.) is sensitive to waterlogging, its ability to form adventitious roots facilitates the diffusion of oxygen and allows the plant to survive waterlogging. To provide comprehensive insight into the adventitious rooting in response to waterlogging of melon, global transcriptome changes during this process were investigated. Of the 17,146 genes expressed during waterlogging, 7363 of them were differentially expressed in the pairwise comparisons between different waterlogging treatment time points. A further analysis suggested that the genes involved in sugar cleavage, glycolysis, fermentation, reactive oxygen species scavenging, cell wall modification, cell cycle governing, microtubule remodeling, hormone signals and transcription factors could play crucial roles in the adventitious root production induced by waterlogging.
