Analytical and clinical validation of diagnostic tests for the detection of leucospermia in beef bulls.

The objectives of this study were to validate diagnostic tests to detect polymorphonuclear cells (PMNs) in bull semen, and to determine the prevalence of leucospermia in beef bulls with varying semen quality. We hypothesized that all tests have comparable diagnostic value, and that leucospermia is more prevalent in unsatisfactory breeders in association with poor semen quality. For the analytical validation, one ejaculate was obtained from five bulls.

Digital home care interventions and quality of primary care for older adults: a scoping review.

Background: Population aging is forcing the transformation of health care. Long-term care in the home is complex and involves complex communication with primary care services. In this scenario, the expansion of digital health has the potential to improve access to home-based primary care; however, the use of technologies can increase inequalities in access to health for an important part of the population.

Shelf-Life Management and Ripening Assessment of 'Hass' Avocado () Using Deep Learning Approaches.

Avocado production is mostly confined to tropical and subtropical regions, leading to lengthy distribution channels that, coupled with their unpredictable post-harvest behavior, render avocados susceptible to significant loss and waste. To enhance the monitoring of 'Hass' avocado ripening, a data-driven tool was developed using a deep learning approach. This study involved monitoring 478 avocados stored in three distinct storage environments, using a 5-stage Ripening Index to classify each fruit's ripening phase based on their shared characteristics.

Machine learning determines stemness associated with simple and basal-like canine mammary carcinomas.

Simple and complex carcinomas are the most common type of malignant Canine Mammary Tumors (CMTs), with simple carcinomas exhibiting aggressive behavior and poorer prognostic. Stemness is an ability associated with cancer initiation, malignancy, and therapeutic resistance, but is still few elucidated in canine mammary tumor subtypes. Here, we first validated, using CMT samples, a previously published canine one-class logistic regression machine learning algorithm (OCLR) to predict stemness (mRNAsi) in canine cancer cells.

Observation of a single protein by ultrafast X-ray diffraction.

The idea of using ultrashort X-ray pulses to obtain images of single proteins frozen in time has fascinated and inspired many. It was one of the arguments for building X-ray free-electron lasers. According to theory, the extremely intense pulses provide sufficient signal to dispense with using crystals as an amplifier, and the ultrashort pulse duration permits capturing the diffraction data before the sample inevitably explodes.

Structure of the Tpp49Aa1 pesticidal protein elucidated from natural crystals using MHz-SFX.

The proteins Tpp49Aa1 and Cry48Aa1 can together act as a toxin toward the mosquito and have potential use in biocontrol. Given that proteins with sequence homology to the individual proteins can have activity alone against other insect species, the structure of Tpp49Aa1 was solved in order to understand this protein more fully and inform the design of improved biopesticides. Tpp49Aa1 is naturally expressed as a crystalline inclusion within the host bacterium, and MHz serial femtosecond crystallography using the novel nanofocus option at an X-ray free electron laser allowed rapid and high-quality data collection to determine the structure of Tpp49Aa1 at 1.

Methods: Tomographic scans of first molars (1M) were performed in dry skulls in the absence and presence of titanium (TI) and zirconia (ZI) dental implants. FI grades were simulated in the alveoli of the 1Ms.

Screening for diminished ovarian reserve in Portugal: a cost-saving answer to shorten the fertility journey.

Assess the budget impact of nationwide screening for diminished ovarian reserve (OR), via anti-Müllerian hormone (AMH) levels, to the Portugal National Health System (NHS). The clinical journey was determined using literature and the family planning decision-making process/response using survey results. A panel of four local clinicians validated all assumptions/inputs.

Low Expression Loci and the Use of Pronase in Flow Cytometry Crossmatch.

Pronase treatment of lymphocytes has been used to improve the specificity and sensitivity of flow cytometric crossmatch, especially B-cell flow cytometric crossmatch, due to the presence of Fc receptors on the cell surface. Some limitations have been reported in the literature: false negatives due to the reduction of major histocompatibility complex expression and false-positive T cells in HIV+ patients due to exposure to cryptic epitopes. This study aimed to evaluate the effect of pronase in our assays, using untreated and treated cells with 2.

Phase behaviour and adsorption of deoxyribonucleic acid onto an azobenzene liquid crystalline ligand at the interfaces.

Azobenzene liquid crystalline (ALC) ligand contains a cholesteryl group linked to an azobenzene moiety through a carbonyl dioxy spacer (C7) and terminated with an amine group as a polar head. The phase behaviour of the C7 ALC ligand at the air-water (A-W) interface is investigated employing surface manometry. The surface pressure-area per molecule isotherm shows that C7 ALC ligand exhibit two different phases following the phase sequence viz.

Digital health interventions and quality of home-based primary care for older adults: A scoping review protocol.

Introduction: The use of digital health interventions has expanded, particularly in home-based primary care (HBPC), following the increase in the older adult population and the need to respond to the higher demand of chronic conditions, weakness and loss of autonomy of this population. There was an even greater demand with COVID-19 and subsequent isolation/social distancing measures for this risk group. The objective of this study is to map and identify the uses and types of digital health interventions and their reported impacts on the quality of HBPC for older adults worldwide.

Lung Injury Is Induced by Abrupt Increase in Respiratory Rate but Prevented by Recruitment Maneuver in Mild Acute Respiratory Distress Syndrome in Rats.

Background: Gradually changing respiratory rate (RR) during time to reduce ventilation-induced lung injury has not been investigated. The authors hypothesized that gradual, compared with abrupt, increments in RR would mitigate ventilation-induced lung injury and that recruitment maneuver before abruptly increasing RR may prevent injurious biologic impact.

Methods: Twenty-four hours after intratracheal administration of Escherichia coli lipopolysaccharide, 49 male Wistar rats were anesthetized and mechanically ventilated (tidal volume, 6 ml/kg; positive end-expiratory pressure, 3 cm H2O) with RR increase patterns as follows (n = 7 per group): (1) control 1, RR = 70 breaths/min for 2 h; (2) and (3) abrupt increases of RR for 1 and 2 h, respectively, both for 2 h; (4) shorter RR adaptation, gradually increasing RR (from 70 to 130 breaths/min during 30 min); (5) longer RR adaptation, more gradual increase in RR (from 70 to 130 breaths/min during 60 min), both for 2 h; (6) control 2, abrupt increase of RR maintained for 1 h; and (7) control 3, recruitment maneuver (continuous positive airway pressure, 30 cm H2O for 30 s) followed by control-2 protocol.

Effects of trying to conceive using an every-other-day strategy versus fertile window monitoring on stress: a 12-month randomized controlled trial.

Study Question: Can animation videos on how to optimize the chances of pregnancy influence stress, anxiety, depression and sexual functioning of individuals trying to conceive (TTC)?

Summary Answer: There were no differences between those educated to have intercourse every other day, on the fertile window and a control group (CG), and depression and sexual dysfunction significantly increased over time for all arms.

What Is Known Already: Recent findings indicate that time to pregnancy can be significantly shortened by targeting the fertile period, but some reproductive care guidelines recommend instead the practice of intercourse every other day on the basis that it is less stressful to the couple. Evidence to support guidelines on how to preserve well-being and psychosocial adjustment and optimize pregnancy chances is lacking.

A Screening of Epigenetic Therapeutic Targets for Non-Small Cell Lung Cancer Reveals PADI4 and KDM6B as Promising Candidates.

Despite advances in diagnostic and therapeutic approaches for lung cancer, new therapies targeting metastasis by the specific regulation of cancer genes are needed. In this study, we screened a small library of epigenetic inhibitors in non-small-cell lung cancer (NSCLC) cell lines and evaluated 38 epigenetic targets for their potential role in metastatic NSCLC. The potential candidates were ranked by a streamlined approach using in silico and in vitro experiments based on publicly available databases and evaluated by real-time qPCR target gene expression, cell viability and invasion assays, and transcriptomic analysis.
