While cisplatin is an effective anti-tumor treatment, it induces ototoxicity through mechanisms involving DNA damage, oxidative stress, and programmed cell death. Rho-associated coiled-coil-containing protein kinase (ROCK) is essential for numerous cellular processes, including apoptosis regulation. Studies have suggested that ROCK inhibitors could prevent apoptosis and promote regeneration.

Background: Atrial fibrillation (AF) is common in COVID-19 patients. The impact of AF on major-adverse-cardiovascular-events (MACE defined as all-cause mortality, myocardial infarction, ischemic stroke, cardiac failure or coronary revascularisation), recurrent AF admission and venous thromboembolism in hospitalised COVID-19 patients is unclear.

Methods: Patients admitted with COVID-19 (1-January-2020 to 30-September-2021) were identified from the New South Wales Admitted-Patient-Data-Collection database, stratified by AF status (no-AF vs prior-AF or new-AF during index COVID-19 admission) and followed-up until 31-Mar-2022.

Introduction: Australian breast cancer survivors are at increased risk of cardiovascular disease and mortality, partly due to behavioural risk factors, including unhealthy diet and physical inactivity. Guidelines recommend health promotion delivered by general practitioners (GPs), but resources (ie, time and funding) are limited. Text message interventions sent from general practice to survivors may offer a low-resource solution but have not been evaluated.

Histone post-translational modifications play pivotal roles in eukaryotic gene expression. To date, most studies have focused on modifications in unstructured histone N-terminal tail domains and their binding proteins. However, transcriptional regulation by chromatin-effector proteins that directly recognize modifications in histone globular domains has yet to be clearly demonstrated, despite the richness of their multiple modifications.

Article Synopsis
  • Major advancements in medical and surgical treatment for cardiovascular disease (CVD) over the past century have led to improved survival rates and shorter hospital stays, increasing the need for ongoing cardiovascular risk management.
  • Despite these advancements, post-discharge care often relies on outdated rehabilitation models that don't adequately address the long-term needs of survivors living with CVD.
  • The paper advocates for reframing cardiac rehabilitation into a broader concept of supporting cardiovascular health through the "5 P's": personalization, processes, patient-centered care, parlance, and partnership, to better engage survivors and improve their outcomes.

Article Synopsis
  • Tumescent anesthesia is linked to longer operation times and increased postoperative issues, prompting a study on tumescentless radiofrequency ablation (RFA) using an internal cooling system.
  • The research compared two patient groups: those receiving conventional tumescent anesthesia (50 patients) and those undergoing non-tumescent RFA (59 patients), finding significantly shorter operation times for the non-tumescent group.
  • Results showed no severe complications in either group, and postoperative pain and minor complications were comparable, suggesting that tumescentless RFA is a safer and more efficient option.

This study proposed an optimized histogel construction method for histological analysis by applying lung cancer patient-derived organoids (PDOs) to the developed histo-pillar strip. Previously, there is the cultured PDOs damage problem during the histogel construction due to forced detachment of the Matrigel spots from the 96-well plate bottom. To address this issue, we cultured PDO on the proposed Histo-pillar strips and then immersed them in 4% paraformaldehyde fixation solution to self-isolate PDO without damage.

Biological assays involve the lysis of biological particles, enzyme reactions, and gene amplification, and require a certain amount of time for completion. Microfluidic chips are regarded as powerful devices for biological assays and diagnostics; however, they cannot achieve a high mixing efficiency, particularly in some time-consuming biological reactions. Herein, we introduce a microfluidic reverse-Tesla (reTesla) valve structure in which the fluid is affected by vortices and branch flow convergence, resulting in flow retardation and a high degree of mixing.

Background: Coronary heart disease (CHD) is the leading cause of deaths and disability worldwide. Cardiac rehabilitation (CR) effectively reduces the risk of future cardiac events and is strongly recommended in international clinical guidelines. However, CR program quality is highly variable with divergent data systems, which, when combined, potentially contribute to persistently low completion rates.
