The cleavage stage plays a crucial role in embryo development, characterized by a swift surge in cell proliferation alongside the accurate genetic material transmission to offspring. To delve into the characteristics of sex development during the cleavage stage of embryos, we generated the full-length transcriptome of male and female cleavage-stage embryos using Oxford Nanopore Technologies (ONT). Notably, this investigation represents the first sequencing effort distinguishing between genders in embryos.

From the Department of Medicine, University of Toronto, Toronto, Ont. (Nabavian); the Department of Surgery, University of Toronto, Toronto, Ont. (Bubis, Jayaraman, Tsang); Hepatobiliary and Pancreatic Surgery Program, St. Joseph's Health Centre Toronto - Unity Health Toronto, Toronto, Ont. (Jayaraman, Tsang).

Background: At the beginning of the COVID-19 pandemic, access to "planned" surgical care was restricted as the health care system responded to the coronavirus. We hypothesized that the pandemic resulted in diagnostic and therapeutic delays, leading to stage migration among patients with malignancies treated with a Whipple procedure.

Background: Follow-up protocols after total hip or knee arthroplasty (THA or TKA, respectively) have little uniformity, which can lead to emergency department (ED) visits for postoperative complications. We sought to determine the incidence and timing of postoperative complications after THA or TKA.

Methods: We conducted a population-based retrospective cohort study of all adults in Ontario who underwent primary THA or TKA between 2010 and 2019.

Integrative Science Center of Germplasm Creation in Western China (CHONGQING) Science City and Southwest University, College of Agronomy and Biotechnology, Southwest University, Chongqing 400715, China.

Background: Sweet orange (Citrus sinensis Osbeck) is a fruit crop of high nutritional value that is widely consumed around the world. However, its susceptibility to low-temperature stress limits its cultivation and production in regions prone to frost damage, severely impacting the sustainable development of the sweet orange industry. Therefore, developing cold-resistant sweet orange varieties is of great necessity.

Little influence of DNA quality on the direct sequencing output of non-human primates' faecal samples.

J Virol Methods

February 2025

Molecular Pathology Unit, Cancer Research Centre, Institute for Medical Research, National Institutes of Health, Ministry of Health Malaysia, Selangor, Malaysia.

Article Synopsis
  • DNA samples for long read sequencing (LRS) are typically expected to be of high purity and concentration, but this study explores the effectiveness of lower quality samples for sequencing Adenovirus from non-human primate feces using Oxford Nanopore Technologies.
  • The analysis revealed that traditional DNA quality indicators, like DNA concentration and freshness, did not significantly influence the sequencing outcomes, suggesting other factors may be more relevant for ONT suitability.
  • Out of 34 DNA samples tested, 21 produced Adenovirus reads, indicating potential avenues for improving sample selection based on identity similarity from preliminary PCR screenings.

The tomato hind (Cephalopholis sonnerati) is an emerging economically important grouper in recent years. With the increasing maturity of sequencing technologies and assembly methodologies, a higher quality reference genome has become both accessible and necessary. In this study, we present two telomere-to-telomere (T2T) gap-free haplotype assemblies of the tomato hind with lengths of 1039.

After the near-complete cessation of commercial whaling, ship collisions have emerged as a primary threat to large whales, but knowledge of collision risk is lacking across most of the world's oceans. We compiled a dataset of 435,000 whale locations to generate global distribution models for four globally ranging species. We then combined >35 billion positions from 176,000 ships to produce a global estimate of whale-ship collision risk.

Switzerland already suffers from the long-predicted shortage of physicians. Moreover, the latter often face long and meandering postgraduate training. At the beginning of their career, most doctors work on internal medicine hospital wards, even though their future may just as well lie in an outpatient or inpatient setting, in general internal medicine or in other disciplines.

Inhaled treatments are essential for obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). However, pressurized metered-dose inhalers (pMDI) use propellant gases, contributing to greenhouse gas (GHG) emissions and thereby to climate change. The use of dry powder inhalers (DPI) or soft mist inhalers (SMI) when clinically appropriate is a way to reduce these emissions.

Sickle cell anemia is the world's most common monogenic disease, with a steady rise in the number of cases also in Switzerland. It presents as regenerative anemia and recurrent vaso-occlusive episodes, which can impact all organs. Acute and chronic complications increase morbidity and mortality, significantly reducing life expectancy compared to the general population.
