the helium method, it is noteworthy that the individuals using the helium method are significantly younger than the individuals who choose other, related, methods.Physical sciences are often overlooked in the field of cancer research. The Physical Sciences in Oncology Initiative was launched to integrate physics, mathematics, chemistry, and engineering with cancer research and clinical oncology through education, outreach, and collaboration. Here, we provide a framework for education and outreach in emerging transdisciplinary fields.Implementation science is the study of methods to ensure the uptake and integration of evidence-based interventions in cancer control. Three key approaches to effective implementation include multilevel approaches, stakeholder engagement, and sustainability. This commentary describes the use and benefits of implementation science as well as opportunities for cancer researchers.Leishmaniasis is caused by several protozoan species of Leishmania, and being endemically present in 98 countries around the world, it is also a severe public-health problem. The available antileishmanial drugs are toxic and yet present risks of recurrent infection. Efforts to find new, effective, and safe oral agents for the treatment of leishmaniasis are continuing throughout the world. This work aimed to evaluate the antileishmania activity of cordiaquinone E (CORe), isolated from the roots of Cordia polycephala (Lam.) I. M. Johnston. Cytotoxicity, and possible mechanisms of action against promastigote and amastigote forms of Leishmania amazonensis were examined. CORe was effective in inhibiting promastigote (IC50 4.5 ± 0.3 µM) and axenic amastigote (IC50 2.89 ± 0.11 µM) growth in concentrations found non-toxic for the host cell (CC50 246.81 ± 14.5 µM). Our results revealed that CORe presents direct activity against the parasite, inducing cell death by apoptosis. CORe present greater activity against intracellular amastigotes (EC50 1.92 ± 0.2 µM), yet with much higher selectivity indexes than the reference drugs, being respectively more benign towards RAW 264.7 macrophages than meglumine antimoniate and amphotericin B, (respectively by 4.68 and 42.84 fold). The antiamastigote activity was associated with increased TNF-α, IL-12, NO, and ROS levels, as well as decreased IL-10 levels. These results encourage the progression of studies on this compound for the development of new leishmanicidal agents.

Understanding the immunological responses in COVID-19 patients during their recovery period is essential to the development of a vaccine and herd immunity.

This retrospective cohort study screened 233 patients admitted to the First Hospital of Changsha, China with COVID-19 from January 17th to February 29th, 2020. After completion of SARS-CoV2-specific immunoglobulins, and T cells tests at 2-week and 3-month follow-up points after discharge, 87 were enrolled. Wilcoxon signed-rank test was performed to assess changes in the values of IgG and IgM, the number of CD3+, CD4+ and CD8+ T cells, and CD4+/CD8+ ratio during the 3-month follow-up. Linear regressions were used to evaluate the associations of immunological changes and medications during hospitalization.

The positive rate of IgG decreased from 98.6% (40/41) to 85.4% (35/41) in men and 100% (43/43) to 76.7% (33/43) in women, whereas IgM declined from 34.1% (14/41) to 12.2% (5/41) in men and 37.2% (16/43) to 27.9% (12/43) in women during the follow-up. CD4+ T cells increased from (median (IQR), 484 (384-635)) cells/ul to 543 (414-657) cells/ul (P=0.01). ADH-1 mouse Antibiotic use was negatively associated with IgG change (mean change [95%CI], 8.08 [0.80-15.37] U, P=0.03), and glucocorticoid use was positively related to increased CD4+ T cells (100.85 [16.56-185.15] cells/ul, P=0.02).

This study demonstrated that the positive rates and values of IgG and IgM decreased in COVID-19 patients over a 3-month follow-up, while CD4+ T cells significantly increased. Moreover, we found that antibiotic use during hospitalization was associated with IgG decrease, and glucocorticoid use was associated with increases in CD4+ T cells.

Since current treatment available for OA has limited efficacy, it is urgent to elucidate the pathogenesis of OA. Therefore, we aimed at elucidating the specific regulatory role of LINC00671 in OA progression. Differentially expressed lncRNAs were initially screened using the OA profile. LINC00671, ONECUT2, and Smurf2 expression in OA cartilage tissues were determined, while their interaction was verified by RNA-pull down assay, ChIP, and dual-luciferase reporter gene assay. After chondrocytes were transfected with shRNA and overexpressed plasmids, the proliferation and apoptosis were determined. Meanwhile, extracellular matrix (ECM)-related proteins were detected by Western blot analysis. Establishment of the OA model was performed by surgical destabilization of the medial meniscus (DMM) surgery in mice. Upregulation of LINC00671, ONECUT2, and Smurf2 expression were detected in OA cartilage. LINC00671 was bound to ONECUT2 and ONECUT2 was conjugated to Smurf2. Overexpression of LINC00671 resulted in inhibited chondrocytes proliferation, enhanced apoptosis, and ECM degradation, which was readily reversed by silencing ONECUT2 or Smurf2. Furthermore, LINC00671 induced GSK-3β ubiquitination and upregulated β-catenin expression through Smurf2. In vivo experiment revealed that silencing of LINC00671 or GSK-3β activator resulted in alleviated ECM degradation and ameliorated OA progression. Collectively, these data demonstrated that LINC00671 exacerbates OA progression through GSK-3β ubiquitination by upregulating ONECUT2-mediated Smurf2.
