R software (version 3.6.0) was used to perform the statistical analysis.Results We included 74 patients and 40 controls in the cross-sectional study. Plasma calprotectin levels were higher in uveitis patients compared to those of controls (p = .003), being higher in younger patients and patients with posterior uveitis. No correlation between calprotectin and anterior chamber inflammation degree was found (p = .198). For the prospective study, we included 36 patients. We found no significant differences in calprotectin levels between active and inactive uveitis (p = .344).Conclusions Plasma calprotectin levels are elevated in uveitis patients and are influenced by age and anatomical location of uveitis. Further investigation is needed to assess the relationship between calprotectin and uveitis activity.San Huang Decoction (SHD), a Chinese herb formula, has been popularly prescribed in the clinical treatment of patients suffering from breast cancer. The aim of this study was to explore the anti-angiogenic effects of SHD in breast cancer and explain the underlying mechanism. Transwell and Matrigel assays showed that SHD reduced human umbilical vein endothelial cell migration and tubule formation and ELISA and qRT-PCR assays demonstrated its mediation of vascular endothelial growth factor (VEGF) expression. siRNA silencing of aurora kinase A (AURKA) produced results similar to those obtained by inhibition of AURKA with SHD. In addition, a chorioallantoic membrane assay was carried out to directly examine the effect of SHD on breast cancer anti-angiogenesis and immunofluorescence and immunohistochemical staining analysis showed that SHD reduced the expression of CD31, AURKA, and VEGF in a xenograft model. Furthermore, SHD regulated extracellular signal-regulated kinase expression in breast cancer cells, which was examined by western blotting. In conclusion, our findings indicated that SHD treatment mimicked the decrease in tumor neovascularization in breast cancer cells after the siRNA-mediated knockdown of AURKA. Thus, SHD may inhibit tumor angiogenesis in breast cancer by targeting AURKA and downregulating the ERK signaling pathway.

Three million African patients need a neurosurgical consultation every year, but there are not enough neurosurgeons to meet this need. Efforts have been made to increase the neurosurgical capacity through the creation of training programs in Africa. Although these programs have been successful, there is still a long way to go. Aspiring African neurosurgeons (AANs) will become neurosurgeons in the future if they are given the resources and opportunities. The authors set out to understand the perceptions, needs, and difficulties faced by AANs.

An e-survey containing 45 questions was created using Google Forms and distributed via social media. The survey was anonymous, and it was distributed from June 2, 2020, to June 16, 2020. Summary descriptive statistics and the Chi-Square test were calculated. The

-value was considered to be significant below .05.

A total of 221 AANs aged 23.5 ± 3.3 years and from 22 African countries responded to the survey. Most were male (66.1%) and medical students (84.6%). Few had assisted a neurosurgical intervention in-person (24.9%), had a mentor (29.0%) or attended a journal club (10.3%). A small proportion was unwilling to train in their home country (19.5%) or a neighboring country (16.3%). The top three reasons for choosing neurosurgery were prestige, advice from a family member, and projected income. Also, respondents felt neurosurgery was expensive.

AANs are passionate about neurosurgery but lack the information, guidance, or opportunities to fulfil their wish.

The National Cancer Institute (NCI) has selected six compounds to evaluate their antiproliferative activity in vitro against 60 human cancer cells lines. Preliminary screening of the examined compounds indicated promising anticancer activity against number of cell lines. The enzyme inhibitory activity against VEGFR-2 was evaluated and IC50 of the tested compounds ranged from 0.57 µM to 1.48 µM. The most potent derivatives Vd and Ve were subjected to further investigations. A cell cycle analysis showed that both compounds mainly arrest HCT-116 cell cycle in the G2/M phase. Annexin V-FITC apoptosis assay showed that Vd and Ve induced an approximately 18.7-fold and 21.2-fold total increase in apoptosis compared to the control. Additionally, molecular docking study was performed against VEGFR (PDB ID 4ASD) using MOE 2015.10 software and Sorafenib as a reference ligand.This study examined the association between coffee consumption and all-cause mortality in patients with a prior acute myocardial infarction or unstable angina. Data were from the prospective study ERICO, totalising 928 patients with Acute Coronary Syndrome (ACS). During 4 years' follow-up, a total of 111 deaths occurred. Quinine ic50 Moderate coffee consumption (1-2 and 2-3 cups/day) was inversely associated with total mortality (HR 0.13, 95% CI 0.06-0.29 and 0.22, 95% CI 0.13-0.39, respectively). For patients with higher coffee consumption (>3 cups/day), there was a positive association with mortality (HR 2.12, 95% CI 1.06-4.24). After stratification by smoking status, the analysis revealed lower risk of mortality in never and former smokers, drinking 1-2 and 2-3 cups/day. Among current smokers there was a positive association between >3 cups/day and mortality. The moderate consumption of coffee was associated with lower risk of all-cause mortality in patients with a prior ACS, particularly in non-smokers.The usage of the chemotherapeutic agent methotrexate (MTX) was associated with hepatotoxicity that minimized its clinical use. The Ginkgo biloba extract (GBE) was used before to alleviate the MTX-induced liver injury through its antioxidant activity. This work was carried out to elucidate other molecular hepatoprotective mechanisms of GBE via examining the IL-6/STAT3 pathway in addition to the miRNA-21 expression in hepatic tissue. Sprague Dawley rats were allocated into four groups normal control (NC); Ginkgo biloba extract control (GBEC); methotrexate (MTX); and Ginkgo biloba extract and methotrexate (GBE + MTX) group. GBE was administered orally 60 mg/kg/day for 10 days while MTX was intraperitoneally injected with 20 mg/kg on day 5. After the experiment, the serum was separated for liver enzyme determination while liver tissues were collected for biochemical and histopathological examinations. MTX induced marked elevation in the liver enzymes, hepatic IL-6, and HGF mRNA expressions, phospho-STAT3/STAT3 ratio, and miRNA-21 hepatic expression when compared with the NC group.
