Many of the plant-derived compounds used in chemotherapies are currently produced by semisynthesis, which results in limited supplies at exorbitant market prices. However, the synthetic biology era, which began ca 15 years ago, has progressively yielded encouraging advances by using engineered microbes for the practical production of cheaper plant anticancer drugs.An exponential diffusion of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) prompted Italian Institutions to take extraordinary healthcare restrictive measures since 8th March 2020, declaring quarantine for COVID-19 (1).Programmed death 1 (PD1) has emerged as a major inhibitor of antitumor T cells, and anti-PD1 therapies have demonstrated clinical efficacy in multiple cancers. However, the impact of PD1 on other immune cells had remained unclear. A recent study by Strauss et al. describes how myeloid cell-intrinsic PD1 signaling limits myelopoiesis in cancer pertinent to anti-PD1 therapies.Health care reform continues to be a topic of debate among lawmakers, politicians, physicians, and citizens of the United States. In recent years, proposed changes to the health care industry have grown in both granularity and popularity, with the possibility of adapting a single-payer health insurance system reaching an all-time high. The implications of such a policy are far-reaching and can be challenging to conceptualize, especially in isolation. The purpose of this article is to review some of the anticipated changes under this new system, specifically as they pertain to the field of plastic surgery.Because of the individualized nature of drug and therapeutic treatments, clinical trials require participants who represent the diversity of the patient base. If early trials do not have a broad patient base, it can be difficult to know who may or may not benefit from or respond to a treatment later. learn more In addition to diversity in recruitment, informed consent during participation is also crucial. If participants do not fully understand what they are signing up for, they may become confused, mistrustful, or drop out of a trial altogether, confusing investigators and possibly affecting the generalizability of a study. To explore the incorporation of health literacy practices into clinical trials, the Roundtable on Health Literacy convened a workshop titled Clinical Trials Practice and Impact on April 11, 2019, in Washington, DC. The workshop presentations and discussion centered around issues related to the challenges or barriers for diverse populations' participation in clinical trials, best practices for clinical trial sites and researchers incorporating health literacy practices, and effective health literacy strategies for clear communication with participants. This publication summarizes the presentation and discussion of the workshop.Coronavirus disease 2019 (COVID-19) is a respiratory disorder caused by the highly contagious SARS-CoV-2. The immunopathological characteristics of COVID-19 patients, either systemic or local, have not been thoroughly studied. In the present study, we analyzed both the changes in the number of various immune cell types as well as cytokines important for immune reactions and inflammation. Our data indicate that patients with severe COVID-19 exhibited an overall decline of lymphocytes including CD4+ and CD8+ T cells, B cells, and NK cells. The number of immunosuppressive regulatory T cells was moderately increased in patients with mild COVID-19. IL-6, IL-10, and C-reactive protein were remarkably up-regulated in patients with severe COVID-19. In conclusion, our study shows that the comprehensive decrease of lymphocytes, the elevation of IL-6, IL-10, and C-reactive protein are reliable indicators of severe COVID-19.We present the case of a 65-year-old man, who was diagnosed at colonoscopy with a stenosing sigmoid adenocarcinoma, 30 cm from the anal verge. Further studies included computerized tomography, which showed a large sigmoid colon tumour with signs of a colovesical fistula and no distant metastases. CT Colonography demonstrated no other proximal lesion.Purpose The purpose of this study was to determine if treatment with telmisartan, an angiotensin II type 1 receptor blocker (ARB), protects against retinal ganglion cell (RGC) degeneration in a mouse glaucoma model with induced elevation of intraocular pressure (IOP). Methods IOP elevation was induced by injection of polystyrene microbeads into the anterior chamber of the right eye of 3-month-old C57BL/6J mice, with the left eye serving as contralateral control. Starting the day of microbead injection, mice were maintained on solid food pellets with or without incorporated telmisartan. IOP was measured by Tono Lab tonometry prior to and weekly after microbead injection. Twelve weeks postinjection, mice were euthanized to obtain optic nerves for analysis of RGC axons. The total numbers of optic nerve axons were determined manually and automatedly using AxonJ. Degenerating axons were counted manually. Results IOP elevation induced by microbead injection was similar in magnitude and duration in vehicle and telmisartan-fed mice, although IOP was reduced 5.8% in uninjected mice treated with telmisartan (P = 0.0027). Axon loss determined by manual and automated methods was greater in vehicle compared to telmisartan-treated mice (manual 9.5% vs. 1.8%, P = 0.044; automated 14.2% vs. 2.9%, P = 0.0375). An increase in the percent of axons undergoing degeneration was observed in nerves from microbead-injected eyes that was greater in vehicle-treated compared to telmisartan-treated mice (49.0% vs. -0.58%, P = 0.0019). Conclusions Elevation of IOP by microbead injection led to loss of RGC axons in vehicle-treated mice that was largely prevented by telmisartan treatment, suggesting a neuroprotective effect of telmisartan.Coronavirus disease 2019 (COVID-19) has rapidly spread to more than 200 countries and areas. As of May 11, 2020, more than 4 million cases have been confirmed globally and more than 280000 deaths have been recorded. In China, Italy and America, the mortality was 5.5% (4644/84451), 14.0% (30739/219814) and 6.1% (78652/1298287), respectively.1.
