The incidence, distribution, and macro- and microscopic structures of left ventricular false tendons (LVFTs) in the cat heart were studied using 25 normal and 57 diseased hearts. The fibrous bands were observed in the left ventricle of all 82 cat hearts examined and most commonly extended between the papillary muscles and the ventricular septum. Histologically, the LVFTs were composed of central Purkinje fibres and surrounding dense collagenous fibres covered by endothelium. There was no appreciable difference in the incidence, distribution or morphology of LVFTs between the normal and the diseased hearts, indicating that LVFTs are a common anatomic variant in the cat heart.

Photosynthetic microbes have evolved and successfully adapted to the ever-changing environmental conditions in complex microhabitats throughout almost all ecosystems on Earth. In the absence of light, they can sustain their biological functionalities through aerobic respiration, and even in anoxic conditions through anaerobic metabolic activity. For a suspension of photosynthetic microbes in an anaerobic environment, individual cellular motility is directly controlled by its photosynthetic activity, i.

The recent COVID-19 pandemic offers a rare opportunity to understand how citizens attribute responsibility for governments' responses to unanticipated negative-and in this case, systemic-exogenous shocks. Classical accounts of responsibility are complicated when crises are pervasive, involve multiple valence dimensions, and where individuals can make relative assessments of performance. We fielded a conjoint experiment in 16 countries with 22,147 respondents.

Using genetic data to infer evolutionary distances between molecular sequence pairs based on a Markov substitution model is a common procedure in phylogenetics, in particular for selecting a good starting tree to improve upon. Many evolutionary patterns can be accurately modelled using substitution models that are available in closed form, including the popular general time reversible model (GTR) for DNA data. For more complex biological phenomena, such as variations in lineage-specific evolutionary rates over time (heterotachy), other approaches such as the GTR with rate variation (GTR ) are required, but do not admit analytical solutions and do not automatically allow for likelihood calculations crucial for Bayesian analysis.

Cancer treatments such as surgery and chemotherapy have several limitations, including ineffectiveness against large or persistent tumors, high relapse rates, drug toxicity, and non-specificity of therapy. Researchers are exploring advanced strategies for treating this life-threatening disease to address these challenges. One promising approach is targeted drug delivery using prodrugs or surface modification with receptor-specific moieties for active or passive targeting.

Background: Given the increasing prevalence of antiplatelet agent use and the lack of high-quality evidence, the CAPTAIN trial aimed to investigate the safety and provide recommendations on continuing acetylsalicylic acid perioperatively in patients undergoing elective laparoscopic totally extraperitoneal inguinal hernia repair (LIHR).
Methods: The CAPTAIN trial was a multicentre, surgeon blind, randomized controlled trial conducted from April 2016 to April 2023. Patients undergoing LIHR were eligible for inclusion.
