Probing spin effects in phycocyanin using Janus-like ferromagnetic microparticles.

In an era of interdisciplinary scientific research, new methodologies are necessary to simultaneously advance several fields of study. One such case involves the measurement of electron spin effects on biological systems. While magnetic effects are well known in biology, recent years have shown a surge in published evidence isolating the dependence on spin, rather than magnetic field, in biological contexts.

Pharmacological Enhancement of Adult Hippocampal Neurogenesis Improves Behavioral Pattern Separation in Young and Aged Male Mice.

Background: Impairments in behavioral pattern separation (BPS)-the ability to distinguish between similar contexts or experiences-contribute to memory interference and overgeneralization seen in many neuropsychiatric conditions, including depression, anxiety, posttraumatic stress disorder, dementia, and age-related cognitive decline. Although BPS relies on the dentate gyrus and is sensitive to changes in adult hippocampal neurogenesis, its significance as a pharmacological target has not been tested.

Methods: In this study, we applied a human neural stem cell high-throughput screening cascade to identify compounds that increase human neurogenesis.

Constellations of Depressive Symptoms, Substance Use, and Risky Sexual Behavior Among Higher Education Students: A Moderated Mediation Analysis of Mask-Wearing Practice During COVID-19.

Mental health and substance use emerged as critical factors associated with health risk behaviors during the COVID-19 pandemic, and its importance has only grown in the post-pandemic period, particularly among priority groups like higher education students. To enhance our understanding of how mental health and substance use factors interact with preventive measures like mask-wearing to affect risky sexual behaviors (RSBs), our study examined the associations between depressive symptoms, substance use, and RSBs among college and university students in the United States. We specifically aimed to assess the impact of mask-wearing on the association between depressive symptoms, binge drinking and marijuana use, and RSBs during the pandemic.

The Role of the Six-Minute Walk Test in the Functional Evaluation of the Efficacy of Rehabilitation Programs After COVID-19.

Patients with COVID-19 suffering in the acute phase from both the sequelae of the disease and prolonged immobilization require a rehabilitation phase for functional recovery and a comprehensive functional evaluation. This study proposes using the 6-Minute Walk Test (6MWT) as a global functional assessment tool to quantify rehabilitation outcomes in post-COVID patients. Additionally, investigating the effect of High-Intensity Laser Therapy (HILT) on patients with musculoskeletal comorbidities was another key research question.

Adaptation of the normative rating procedure for the International Affective Picture System to a remote format.

Background: The Self-Assessment Manikin (SAM), a pictorial scale for the measurement of pleasure and arousal dimensions of emotions, is one of the most applied tools in the emotion research field.

Objective: We present a detailed description of a remote method to collect affective ratings in response to pictures by using the SAM scale.

Methods: To empirically validate our remote method, we conducted a study using a digitized version of the SAM scale and delivered online didactic instructions that followed the normative rating procedure for the International Affective Picture System (IAPS) to the participants.

Altered Brain Reactivity to Food Cues in Undergraduate Students with Disordered Eating Behaviors.

Purpose: A growing body of evidence has shown that electroencephalography (EEG) is an interesting method of assessing the underlying brain physiology associated with disordered eating. Using EEG, we sought to evaluate brain reactivity to hyper-palatable food cues in undergraduate students with disordered eating behavior (DEB).

Methods: After assessing the eating behaviors of twenty-six undergraduate students using the Eating Attitudes Test (EAT-26), electroencephalographic signals were recorded while the participants were presented with pictures of hyper-palatable food.

Beyond the needle: a qualitative exploration of Sierra Leonean healthcare workers' post COVID-19 vaccination experiences.

The global health crisis precipitated by the COVID-19 pandemic underscored the necessity of swift vaccine development and distribution to curb virus transmission. However, discussions on vaccine acceptance and hesitancy have predominantly focused on pre-vaccination attitudes, often overlooking the significance of post-vaccination experiences in shaping individual and communal attitudes toward vaccines. This oversight is particularly critical among healthcare workers in low- and middle-income countries (LMICs), who play a dual role in combating the pandemic and influencing public vaccine sentiment.

Primiparous sow behaviour on the day of farrowing as one of the primary contributors to the growth of piglets in early lactation.

Large White and Meishan sows differ in maternal ability and early piglet growth. We investigated the relationships between 100 maternal traits, grouped into 11 blocks according to the biological function they describe and litter growth over three successive periods after birth (D0-D1, D1-D3 and D3-D7; D0 starting at the onset of farrowing), as a measure of sow investment in early piglet production. Within- and between-breed variation was exploited to cover a maximum of the variability existing in pig maternal populations.

The Active Tumor Vaccination in Combination With CDK4/6 Inhibitor Treatment: A Case Report.

Background: Current standard treatment for metastatic breast cancer (MBC) involves cyclin-dependent kinase 4/6 (CDK4/6) inhibitors with endocrine therapy, showing potential in enhancing anti-tumor immune responses.

Case Report: This report details a clinical case of MBC where palbociclib was co-administered with letrozole. The integration of allogeneic tumor vaccination to this treatment led to heightened interferon-γ production, expansion of CD8+ and NK cell populations, and positive delayed-type hypersensitivity reactions, indicating successful development of anti-tumor immunity.

Genetic parameters of feeding behaviour traits in ducks bred for foie gras production.

The mule duck accounts for over 90% of French foie gras production, a sector where feed represents two-thirds of production costs. This study focuses on analysing the feeding behaviours of the mule duck and its parental populations (Pekin and Muscovy) using automated feeders. To assess feed efficiency, feed conversion ratio and residual feed intake were analysed, along with six traits derived at the daily and meal levels.

Successfully physical therapy program for functional respiratory rehabilitation after lung transplant surgery - case report.

The first lung transplant (LT) was made in Romania in 2018 at a 36-year-old male patient with chronic obstructive pulmonary disease (COPD). The study follows the first LT rehabilitation by describing the physical therapy program (PTP), the measurements of body mass and appendicular skeletal muscle mass (ASM) by bio-impedancemetry analysis (BIA) and the functional capacity assessment realized by the six-minute walk test (6MWT) and by the functional respiratory tests (FRTs) in order to evaluate the effectiveness of functional respiratory rehabilitation in this case during a period of one year. In parallel, repeated transbronchial biopsies were performed after six weeks, three months, six months and one year since the transplant.

Integrating computer vision algorithms and RFID system for identification and tracking of group-housed animals: an example with pigs.

Precision livestock farming aims to individually and automatically monitor animal activity to ensure their health, well-being, and productivity. Computer vision has emerged as a promising tool for this purpose. However, accurately tracking individuals using imaging remains challenging, especially in group housing where animals may have similar appearances.

Background: This systematic review and meta-analysis investigates the relationship between successful aging (SA) and resilience in older adults, focusing on individuals aged 60 and above, to address a significant gap in understanding how resilience contributes to SA.

Methods: Following the Cochrane review guidelines, we conducted searches in databases such as Web of Science, PsycNet, and PubMed up to December 2021 and used PRISMA as a tool for reporting the results. Our inclusion criteria were studies on psychological resilience and SA in older adults aged 60 and above.

A Social-ecological Perspective on Understanding Facilitators to Access Primary Health Care Services among Ethiopian Immigrant Women in the United States.

Using a social-ecological model (SEM), this qualitative study explored the facilitators of access to primary health care (PHC) among Ethiopian immigrant women in the U.S. Data were collected through in-depth interviews (N=21, ≥18 years) and analyzed thematically using Nvivo12.

CAG repeat mosaicism is gene specific in spinocerebellar ataxias.

Expanded CAG repeats in coding regions of different genes are the most common cause of dominantly inherited spinocerebellar ataxias (SCAs). These repeats are unstable through the germline, and larger repeats lead to earlier onset. We measured somatic expansion in blood samples collected from 30 SCA1, 50 SCA2, 74 SCA3, and 30 SCA7 individuals over a mean interval of 8.

Threat directionality modulates defensive reactions in humans: cardiac and electrodermal responses.

Identification and characterization of unknown disturbances in a structured population using high-throughput phenotyping data and measurement of robustness: application to growing pigs.

Improving the robustness of animals has become a priority in breeding due to climate change, new societal demands, and the agroecological transition. Components of animal robustness can be extracted from the analysis of the adaptive response of an animal to disturbance using longitudinal data. Nonetheless, this response is a function of animal robustness as well as of disturbance characteristics (intensity and duration).
