Effect of Danshen for improving clinical outcomes in patients with bladder cancer: a retrospective, population-based study

Introduction: Traditional Chinese Medicine (TCM) has a broad application in healthcare, with Danshen being a notable herb used in Eastern medicine for cancer treatment. This study aims to explore the relationship between Danshen use and cardiovascular risks among bladder cancer patients.Methods: Patients were selected based on a confirmed diagnosis of bladder cancer with specific inclusion and exclusion criteria to control for certain comorbidities and treatments. Utilizing Taiwan’s National Health Insurance data from 2003 to 2013, this retrospective, population-based study identified three groups: 525 patients treated with Danshen, 6,419 patients not treated with TCM, and 4,356 patients treated with TCM but not with Danshen. The Cox proportional hazard model was employed to estimate the risks of Major Adverse Cardiovascular Events (MACE) and mortality while accounting for various confounders.Results: The overall incidence of MACEs was significantly lower in the Danshen group (5%) compared to the TCM (8.1%) and non-TCM (9.9%) groups (p < 0.001). The Cox model revealed that bladder cancer patients treated with Danshen had the lowest risk of MACE (adjusted hazard ratio, 0.56; 95% confidence interval, 0.38–0.84) and all-cause mortality (adjusted hazard ratio, 0.60; 95% confidence interval, 0.44–0.82).Discussion: The findings suggest that Danshen reduces the risk of MACE and all-cause mortality in bladder cancer patients, highlighting its potential benefits. This underpins the necessity for further research to substantiate the cardiovascular benefits of Danshen in bladder cancer patients and potentially broaden its application in oncology healthcare

How Culture Influeneces Consumer Loyalty towards Cosmetic Products. A comparision of UK and Taiwanese Consumers

Abstract Culture is one of the most important factors affecting the marketing department to shape their strategy. This is particularly true when facing global marketing. This project is aimed at examining how the culture influences brand loyalty towards cosmetic products by comparing consumer behaviours of UK and Taiwanese consumers. Semi-structured interviews are conducted in order to collect data. By applying a qualitative approach, this project provides an insight of the cultural factors influencing consumer behaviour. Furthermore, some managerial implication and directions of further research are presented in this project

Improvement on thermal performance of a disk-shaped miniature heat pipe with nanofluid

The present study aims to investigate the effect of suspended nanoparticles in base fluids, namely nanofluids, on the thermal resistance of a disk-shaped miniature heat pipe [DMHP]. In this study, two types of nanoparticles, gold and carbon, in aqueous solution are used respectively. An experimental system was set up to measure the thermal resistance of the DMHP with both nanofluids and deionized [DI] water as the working medium. The measured results show that the thermal resistance of DMHP varies with the charge volume and the type of working medium. At the same charge volume, a significant reduction in thermal resistance of DMHP can be found if nanofluid is used instead of DI water

Development of a Virtual Training Program to Reduce Gun Violence Amidst the Covid-19 Era

Firearm deaths and related health issues have increased and disproportionately affected minorities in the COVID-19 era. We developed an accessible virtual training program, including topics on gun violence epidemiology, depression, substance use, intimate partner violence (IPV), intervention resources, safety planning, and COVID-19-related issues. The training program was distributed to participants from the Northeast region, particularly New Jersey, through text, email, and social media. Among the 202 survey responses from the participants, the mean age was 22.6, 50% were male, and 84.4% were minorities. Only 49.5% of participants were familiar with the related topics before the program, with participants having the least knowledge in gun violence epidemiology (9.5%). The mean test score for knowledge on all related topics after the training was 98.0 out of 100. Most participants were satisfied with the training program (92.1%), felt comfortable seeking help (86.1%), and would promote the program (83.7%). The participants were least comfortable seeking help for depression, particularly among non-African and non-Hispanic minority groups. We concluded that brief online interventions can improve community health outreach, knowledge, awareness, and likelihood of help-seeking and treatment. Tailored training programs are needed to target various populations for prevention and intervention

Coordinate Ascent for Off-Policy RL with Global Convergence Guarantees

We revisit the domain of off-policy policy optimization in RL from the perspective of coordinate ascent. One commonly-used approach is to leverage the off-policy policy gradient to optimize a surrogate objective -- the total discounted in expectation return of the target policy with respect to the state distribution of the behavior policy. However, this approach has been shown to suffer from the distribution mismatch issue, and therefore significant efforts are needed for correcting this mismatch either via state distribution correction or a counterfactual method. In this paper, we rethink off-policy learning via Coordinate Ascent Policy Optimization (CAPO), an off-policy actor-critic algorithm that decouples policy improvement from the state distribution of the behavior policy without using the policy gradient. This design obviates the need for distribution correction or importance sampling in the policy improvement step of off-policy policy gradient. We establish the global convergence of CAPO with general coordinate selection and then further quantify the convergence rates of several instances of CAPO with popular coordinate selection rules, including the cyclic and the randomized variants of CAPO. We then extend CAPO to neural policies for a more practical implementation. Through experiments, we demonstrate that CAPO provides a competitive approach to RL in practice.Comment: 47 pages, 4 figure

T Oligo-Primed Polymerase Chain Reaction (TOP-PCR): A Robust Method for the Amplification of Minute DNA Fragments in Body Fluids.

Body fluid DNA sequencing is a powerful noninvasive approach for the diagnosis of genetic defects, infectious agents and diseases. The success relies on the quantity and quality of the DNA samples. However, numerous clinical samples are either at low quantity or of poor quality due to various reasons. To overcome these problems, we have developed T oligo-primed polymerase chain reaction (TOP-PCR) for full-length nonselective amplification of minute quantity of DNA fragments. TOP-PCR adopts homogeneous "half adaptor" (HA), generated by annealing P oligo (carrying a phosphate group at the 5' end) and T oligo (carrying a T-tail at the 3' end), for efficient ligation to target DNA and subsequent PCR amplification primed by the T oligo alone. Using DNA samples from body fluids, we demonstrate that TOP-PCR recovers minute DNA fragments and maintains the DNA size profile, while enhancing the major molecular populations. Our results also showed that TOP-PCR is a superior method for detecting apoptosis and outperforms the method adopted by Illumina for DNA amplification
