However, the limited availability of data for specific enzyme functions, such as conversion efficiency and stereoselectivity, presents challenges for prediction accuracy.

The Mediating Role of Sexual Boredom in Women's Sexual Desire and Satisfaction.

Sexual boredom in women is associated with various levels and dimensions of sexual desire, as well as lower sexual and relationship satisfaction. However, the directionality of these relationships remains unclear. This study aimed to investigate whether sexual boredom mediates the relationship between partner and attractive-other sexual desire and sexual and relationship satisfaction in a sample of 1155 Portuguese women in long-term monogamous relationships.

Transcriptional responses of blastospores after UV-B irradiation.

is widely known for its role as an arthropod biocontrol agent and plant bioinoculant. By using mass-production industrial methods, it is possible to produce large amounts of fungal single-celled propagules (including blastospores) to be applied in the field. However, in the environment, the solar ultraviolet components (particularly UV-B) can harm the fungus, negatively impacting its pathogenicity toward the arthropod pest.

Aging promotes an increase in mitochondrial fragmentation in astrocytes.

Introduction: Brain aging involves a complex interplay of cellular and molecular changes, including metabolic alterations and the accumulation of senescent cells. These changes frequently manifest as dysregulation in glucose metabolism and mitochondrial function, leading to reduced energy production, increased oxidative stress, and mitochondrial dysfunction-key contributors to age-related neurodegenerative diseases.

Methods: We conducted experiments on two models: young (3-4 months) and aged (over 18 months) mice, as well as cultures of senescent and control mouse astrocytes.

Intranasal influenza-vectored vaccine expressing pneumococcal surface protein A protects against Influenza and Streptococcus pneumoniae infections.

Streptococcus pneumoniae and influenza A virus (IAV) are significant agents of pneumonia cases and severe respiratory infections globally. Secondary bacterial infections, particularly by Streptococcus pneumoniae, are common in IAV-infected individuals, leading to critical outcomes. Despite reducing mortality, pneumococcal vaccines have high production costs and are serotype specific.

Characteristics and outcomes of in-hospital patients with Covid-19 and history of tuberculosis: a matched case-control from the Brazilian Covid-19 Registry.

Background: The Covid-19 pandemic caused a negative impact on other infectious diseases control, prevention, and treatment. Consequently, low and middle-income countries suffer from other endemic diseases, such as tuberculosis. This study was designed to compare Covid-19 manifestations and outcomes between patients with previously treated tuberculosis and controls without this condition.

Intercostal Nerve Cryoablation as an Effective Pain Management Strategy in the Nuss Procedure: Reducing Opioid Use and Hospital Stay.

Introduction:  Erector spinae plane (ESP) blocks, thoracic epidural, and patient-controlled analgesia (PCA) have all been used for perioperative pain management in the Nuss procedure without a consensus on what modality produces the best outcomes. Intercostal nerve cryoablation (INC) is a relatively new modality that involves freezing the nerves to prevent pain during recovery. Our hypothesis is that using INC for the Nuss procedure will decrease opioid use, pain scores, and length of stay (LOS) but will increase cost compared with ESP block, thoracic epidural, and PCA.

Well-managed grass is a key strategy for carbon storage and stabilization in anthropized Amazon soils.

Soils under anthropic use in the Amazon region are often associated with soil carbon (C) stock losses. More recently, the restoration of degraded pastures and the introduction of integrated systems have changed this pattern, and soil C accumulation is often observed. This study evaluated an 11-year field experiment to quantify soil C changes and elucidate C stabilization mechanisms in areas under anthropic uses in the southern Amazon of Brazil.
