RESULTS Nuclear immunoreactivity for CDK9 protein was more pronounced in human HB samples and YAP/β-catenin mouse HB tumor tissues than in corresponding surrounding nontumorous liver tissues. CDK9 protein was also expressed in human HB cell lines. Silencing of CDK9 in human HB cell lines did not lead to consistent effects on HB cell growth or YAP target gene expression. Surprisingly, silencing of Cdk9 led to accelerated liver tumorigenesis in YAP/β-catenin mice. CONCLUSION CDK9 is not a major downstream mediator of YAP oncogenic function in HB development and progression. © 2020 Wiley Periodicals, Inc.BACKGROUND To evaluate risk of prostate cancer biochemical recurrence following radical prostatectomy in men receiving versus not receiving testosterone therapy. PATIENTS AND METHODS 850 patients underwent radical prostatectomy by a single surgeon. All patients had preoperative testosterone and sex hormone binding globulin levels drawn; free testosterone was calculated prospectively.152 (18%) patients with low preoperative calculated free testosterone levels and delayed post-operative sexual function recovery were placed on testosterone therapy and proportionately matched to 419 control patients by pathologic Gleason Grade Group and stage. Rates and time to biochemical recurrence (two consecutive prostate specific antigen ≥ 0.2 ng/dl) were compared in univariate and multivariate regression; Cox regression was used to generate a survival function at the mean of covariates. RESULTS Median follow-up was 3.5 years. There were no statistically significant differences in demographics or general health complications All rights reserved.OBJECTIVE To evaluate the functional outcomes of arthroscopic anatomical repair of anterior talofibular ligament (ATFL) in the treatment of chronic lateral ankle instability (CLAI) during medium- and long-term follow-up. METHODS From September 2014 to August 2017, the data of 37 patients (23 males, 14 females; 12 left ankles, 25 right ankles) aged between 21 and 56 years, with an average age of 32.17 ± 6.35 years, presenting with CLAI, was retrospectively analyzed. Among them, 32 injuries were caused by sprain and five injuries were caused by car accidents. The course of the disease lasted for 12 to 60 months, with an average of 26.07 ± 13.29 months. All patients had intact skin around the ankle and no skin lesions. All patients underwent arthroscopic anatomical repair of ATFL, with the fixation of one to two anchors. Pre- and post-operative visual analogue scales (VAS), the American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Score (AOFAS), and the Karlsson Ankle Functional Score (KAFS) were compared tto 1.12 ± 0.13, the AOFAS score increased to 92.53 ± 4.87, and the KAFS score increased to 93.36 ± 6.15. All the follow-up indexes were significantly different from those before surgery. CONCLUSION Arthroscopic anatomical repair of ATFL for CLAI is precise, with less surgical trauma and reliable medium- and long-term effect. © 2020 The Authors.

However, light absorption and scattering significantly prevents penetration to deep brain regions. Herein, we describe the use of gold-coated mechanoresponsive nanovesicles, which consist of liposomes made from the artificial phospholipid Rad-PC-Rad as a tool for the delivery of bioactive molecules into brain tissue. Near-infrared picosecond laser pulses activated the gold-coating on the surface of nanovesicles, creating nanomechanical stress and leading to near-complete vesicle cargo release in sub-seconds. Compared to natural phospholipid liposomes, the photo-release was possible at 40 times lower laser energy. This high photosensitivity enables photorelease of molecules down to a depth of 4 mm in mouse brain. This promising tool provides a versatile platform to optically release functional molecules to modulate brain circuits. © 2020 Wiley-VCH Verlag GmbH & Co.

Our objective was to characterize motor activities throughout the entire colon that possessed persistent rhythmicity and spanning at least 5 cm. METHODS High-resolution colonic manometry using an 84-channel water-perfused catheter was performed in 19 healthy volunteers. Rhythmic activity was assessed during baseline, proximal balloon distention, meal, and bisacodyl administration. KEY RESULTS Throughout the entire colon, a cyclic motor pattern occurred either in isolation or following a high-amplitude propagating pressure wave (HAPW), consisting of clusters of pressure waves at a frequency centered on 11-13 cycles/min, unrelated to breathing. The cluster duration was 1-6 minutes; the pressure waves traveled for 8-27 cm, lasting 5-8 seconds. The clusters itself could be rhythmic at 0.5-2 cpm. The propagation direction of the individual pressure waves was mixed with >50% occurring simultaneous. This high-frequency cyclic motor pattern co-existed with the well-known low-frequency cyclic motor pattern centered on 3-4 cpm. In the rectum, the low-frequency cyclic motor pattern dominated, propagating predominantly in retrograde direction. Proximal balloon distention, a meal and bisacodyl administration induced HAPWs followed by cyclic motor patterns. CONCLUSIONS AND INFERENCES Within cyclic motor patterns, retrograde propagating, low-frequency pressure waves dominate in the rectum, likely keeping the rectum empty; and mixed propagation, high-frequency pressure waves dominate in the colon, likely promoting absorption and storage, hence contributing to continence. Propagation and frequency characteristics are likely determined by network properties of the interstitial cells of Cajal. © 2020 John Wiley & Sons Ltd.PURPOSE Sodium glucose cotransporter 2 (SGLT2) inhibitors are shown to cause small, but significant changes of lipid profiles, we aim to investigate whether such altered lipid profiles can be translated into clinically meaningful changes in dyslipidemia. METHODS PubMed, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for randomized controlled trials (RCTs) that compared SGLT2 inhibitors with placebo or other oral glucose-lowering drugs in patients with type 2 diabetes mellitus and reported the events of dyslipidemia. BL-918 A random-effect meta-analysis was performed to calculate the pooled estimates with risk ratio (RR) for dyslipidemia risk and weighted mean difference for lipid profiles with their 95% confidential intervals (CIs). RESULTS Of 2427 studies identified, 15 RCTs involving 7578 patients were included. This meta-analysis found no association between SGLT2 inhibitors and risk of dyslipidemia (RR 1.13; 95% CI 0.91-1.40). However, SGLT2 inhibitors were significantly associated with increases in total cholesterol by 0.15 mmol/L, low-density lipoprotein cholesterol by 0.12 mmol/L, and high-density lipoprotein cholesterol by 0.07 mmol/L while they can significantly decrease triglycerides by -0.12 mmol/L compared to controls. CONCLUSIONS SGLT2 inhibitors were not associated with increased risk of dyslipidemia. Further trials with longitudinal assessment are needed to assess the effect of SGLT2 inhibitors on trajectories of changes of lipid metabolism. © 2020 John Wiley & Sons Ltd.Discriminative detection of invasive and noninvasive breast cancers is crucial for their effective treatment and prognosis. However, activatable probes able to do so in vivo are rare. Herein, we report an activatable polymeric reporter (P-Dex) that specifically turns on near-infrared (NIR) fluorescent and photoacoustic (PA) signals in response to the urokinase-type plasminogen activator (uPA) overexpressed in invasive breast cancer. P-Dex has a renal-clearable dextran backbone that is linked with a NIR dye caged with an uPA-cleavable peptide substrate. Such a molecular design allows P-Dex to passively target tumors, activate NIR fluorescence and PA signals to effectively distinguish invasive MDA-MB-231 breast cancer from noninvasive MCF-7 breast cancer, and ultimately undergo renal clearance to minimize the toxicity potential. Thus, this polymeric reporter holds great promise for the early detection of malignant breast cancer. © 2020 Wiley-VCH Verlag GmbH & Co.

PATIENTS AND METHODS Men diagnosed with prostate cancer between 1st April 2014 and 2017 in England were identified by the National Prostate Cancer Audit. Administrative hospital data were then used to categorise the type of prostate biopsy and subsequent complications requiring hospital admission. Administrative hospital data were used to identify patients staying overnight immediately after biopsy and those readmitted separately for hospital admissions because of sepsis, urinary retention or haematuria. Procedure related mortality and total length of hospital stay within 30 days was also recorded. Generalised linear models were used to calculate adjusted risk differences (aRD). RESULTS 73,630 men undergoing prostate biopsy were identified. Those having TP biopsy (n=13,723) were more likely to have an overnight hospital stay (12.3% vs 2.4%; aRD 9.7% 95% CI 7.1% to 12.3%), were less likely to be readmitted because of sepsis (1.0% vs 1.4%; aRD -0.4% CI -0.6% to -0.2%), and were more likely to be readmitted with urinary retention (1.9% vs 1.0%; aRD 1.1% CI 0.7% to 1.4%) than those undergoing a TR biopsy (n=59,907). There were no significant differences in the risk of haematuria or mortality. CONCLUSIONS TP biopsy has a lower risk of readmission for sepsis but a higher risk of readmission for urinary retention than TR biopsy. Use of the TP route would prevent one readmission for sepsis in 278 men at the cost of three additional men readmitted for urinary retention. This article is protected by copyright.

The catalytically generated enamine radical cation serves as a carbon radical electrophile that can stereoselectively add to the alkene of an allylic alcohol and initiate ensuing ring-expansion of cyclopropanol or cyclobutanol. This tandem reaction enables the production of a wide range of nonracemic functionalizable α-quaternary-δ-carbonyl cycloketones in high yields and excellent enantioselectivity from simple aldehydes and allylic alcohols. As a key step, the intramolecular reaction was also successfully applied in the asymmetric total synthesis of (+)-cerapicol. © 2020 Wiley-VCH Verlag GmbH & Co.

The underlying assumption is a stationary (time-stable), quasi-linear relationship between tree growth and environment, which however conflicts with basic ecological and evolutionary theory. Indeed, our global assessment of the relevant tree-ring literature demonstrates non-stationarity in the majority of tested cases, not limited to specific proxies, environmental parameters, regions or species. Non-stationarity likely represents the general nature of the relationship between tree-growth proxies and environment. Studies assuming stationarity however score 2 times more citations influencing other fields of science and the science-policy interface. To reconcile ecological reality with the application of tree-ring proxies for climate or environmental estimates, we provide a clarification of the stationarity concept, propose a simple confidence framework for the re-evaluation of existing studies and recommend the use of a new statistical tool to detect non-stationarity in tree-ring proxies.
