The effect of male factors on embryo morphokinetics: a retrospective analysis of 2726 blastocysts.

Purpose: Male infertility may influence fertilization rates, embryo morphology, and implantation rates in in vitro fertilization (IVF) cycles. Oocyte competence plays a major role in embryo development, but there is a limited understanding of the connection between sperm quality, embryo development, and morphokinetic parameters using donor oocytes. The study evaluated if sperm quality may influence the morphokinetic parameters in IVF cycles.

Clinical validation of SARS-CoV-2 electrochemical immunosensor based on the spike-ACE2 complex.

Background And Aims: Advances in health, especially in prevention, diagnosis, and treatment, have significantly impacted the way of facing emerging infectious diseases. Yet, events such as the COVID-19 pandemic have shown that there is still a long way to go. Therefore, an urgent need exists for portable and easily deployable point-of-care (POC) detection tools.

In Silico and In Vitro Identification of 1,8-Dihydroxy-4,5-dinitroanthraquinone as a New Antibacterial Agent against and .

Increasing rates of bacterial resistance to antibiotics are a growing concern worldwide. The search for potential new antibiotics has included several natural products such as anthraquinones. However, comparatively less attention has been given to anthraquinones that exhibit functional groups that are uncommon in nature.

Detection of COVID-19-related biomarkers by electrochemical biosensors and potential for diagnosis, prognosis, and prediction of the course of the disease in the context of personalized medicine.

As a more efficient and effective way to address disease diagnosis and intervention, cutting-edge technologies, devices, therapeutic approaches, and practices have emerged within the personalized medicine concept depending on the particular patient's biology and the molecular basis of the disease. Personalized medicine is expected to play a pivotal role in assessing disease risk or predicting response to treatment, understanding a person's health status, and, therefore, health care decision-making. This work discusses electrochemical biosensors for monitoring multiparametric biomarkers at different molecular levels and their potential to elucidate the health status of an individual in a personalized manner.

SARS-CoV-2 electrochemical immunosensor based on the spike-ACE2 complex.

Rapid, straightforward, and massive diagnosis of coronavirus disease 2019 (COVID-19) is one of the more important measures to mitigate the current pandemics. This work reports on an immunosensor to rapidly detect the spike protein from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The immunosensing device entraps the spike protein linked to angiotensin-converting enzyme host receptor (ACE2) protein in a sandwich between carboxylated magnetic beads functionalized with an anti-spike antibody and an anti-ACE2 antibody, further labeled with streptavidin (poly)horseradish peroxidase (HRP) reporter enzyme.

Functional Nanocarriers for Delivering Itraconazole Against Fungal Intracellular Infections.

Infectious diseases caused by intracellular microorganisms represent a significant challenge in medical care due to interactions among drugs during coinfections and the development of resistance in microorganisms, limiting existing therapies. This work reports on itraconazole (ITZ) encapsulated into functional polymeric nanoparticles for their targeted and controlled release into macrophages to fight intracellular infections. NPs are based on poly (lactic acid-co-glycolic acid) (PLGA) polymers of different compositions, molecular weights, and lactic acid-to-glycolic acid ratios.

Review of serious events in cases of (suspected) child abuse and/or neglect: A RoSE by any other name?

Child abuse and neglect (CAN) cases presenting to health-services may be complex; when things go seriously wrong such as a child death or near miss, cases are reviewed and health-services and professionals subject to intense scrutiny. While there are a variety of mechanisms to review critical incidents in health-services no formal process for the review of cases where child protection is the primary concern exists in Australia. We aimed to develop a systematic process to review serious events in cases of suspected CAN across two health districts in Sydney, so that shared learnings could fuel system change.

Incidence, Distribution, and Association of Spongospora subterranea and Potato mop-top virus in Costa Rica.

A survey was conducted in 39 potato (Solanum tuberosum) fields in Costa Rica to determine incidence and association of Spongospora subterranea f. sp. subterranea and Potato mop-top pomovirus (PMTV).

[Incidence and altitudinal distribution of 13 virus cultures in Solanum tuberosum (Solanaceae) from Costa Rica].

A survey was conducted in 30 fields located at three different altitudes in Cartago, Costa Rica's main potato producing area. Twenty plants were sampled per farm, for a total of 600 samples with 200 samples per altitude. ELISA was used with commercial reagents to independently test for PVX, PVY, PVM, PVA, PVS, PLRV, PMTV, PAMV, PVV, PVT, APLV, APMoV and TRSV.
