Beyond the virus: ecotoxicological and reproductive impacts of SARS-CoV-2 lysate protein in C57Bl/6j female mice.

Since the establishment of the COVID-19 pandemic, a range of studies have been developed to understand the pathogenesis of SARS-CoV-2 infection, vaccine development, and therapeutic testing. However, the possible impacts that these viruses can have on non-target organisms have been explored little, and our knowledge of the consequences of the COVID-19 pandemic for biota is still very limited. Thus, the current study aimed to address this knowledge gap by evaluating the possible impacts of oral exposure of C57Bl/6 J female mice to SARS-CoV-2 lysate protein (at 20 µg/L) for 30 days, using multiple methods, including behavioral assessments, biochemical analyses, and histopathological examinations.

Tailoring Cu-SiO Interaction through Nanocatalyst Architecture to Assemble Surface Sites for Furfural Aqueous-Phase Hydrogenation to Cycloketones.

In this contribution, nanocatalysts with rather diverse architectures were designed to promote different intimacy degrees between Cu and SiO and consequently tune distinct Cu-SiO interactions. Previously synthesized copper nanoparticles were deposited onto SiO (NPCu/SiO) in contrast to ordinarily prepared supported Cu/SiO. NPCu@SiO and SiO@Cu core-shell nanocatalysts were also synthesized, and they were all bulk and surface characterized by XRD, TGA, TEM/HRTEM, H-TPR, XANES, and XPS.

Rare manifestation of pulmonary benign metastasizing leiomyoma: Respiratory failure.

We report a case of a 42-year-old woman diagnosed with pulmonary benign metastasizing leiomyomatosis with a random nodular pattern on image and with a rare clinical condition progressing with respiratory failure and severe hypoxemia. This study is relevant due to the rarity of the tomographic pattern and the patient's clinical presentation. There is no treatment guideline for this comorbidity, which further increases the importance of publishing case reports in the literature.

Impact of the Communities That HEAL Intervention on Buprenorphine-Waivered Practitioners and Buprenorphine Prescribing: A Prespecified Secondary Analysis of the HCS Randomized Clinical Trial.

Importance: Buprenorphine significantly reduces opioid-related overdose mortality. From 2002 to 2022, the Drug Addiction Treatment Act of 2000 (DATA 2000) required qualified practitioners to receive a waiver from the Drug Enforcement Agency to prescribe buprenorphine for treatment of opioid use disorder. During this period, waiver uptake among practitioners was modest; subsequent changes need to be examined.

Influence of Patient and Clinician Gender on Emergency Department HEART Scores: A Secondary Analysis of a Prospective Observational Trial.

Study Objective: Clinical decision aids can decrease health care disparities. However, many clinical decision aids contain subjective variables that may introduce clinician bias. The HEART score is a clinical decision aid that estimates emergency department (ED) patients' cardiac risk.

Barriers and Facilitators to Harm Reduction for Opioid Use Disorder: A Qualitative Study of People With Lived Experience.

Study Objective: Although an increasing number of emergency departments (ED) offer opioid agonist treatment, naloxone, and other harm reduction measures, little is known about patient perspectives on harm reduction practices delivered in the ED. The objective of this study was to identify patient-focused barriers and facilitators to harm reduction strategies in the ED.

Methods: We conducted semistructured interviews with a convenience sample of individuals in Massachusetts diagnosed with opioid use disorder.

Validity and reliability of SEIS-3: An instrument for subjective measuring of strength in older adults.

The use of rating of perceived exertion (RPE) has grown substantially, providing a valuable alternative for exercise intensity monitoring, especially for older adults. However, some challenges, such as cross-cultural validity, age-related differences, and reliability issues, necessitate the development of a concise and user-friendly RPE instrument, particularly for strength training in this population. This study aimed to validate the Subjective Effort Induction Scale (SEIS-3), a simplified tool for measuring effort during strength training.

Effects of High-Biotin Sample Interference on Antibody Concentrations in Sandwich Immunoassays.

The use of antimicrobial growth promoters (AGPs) is banned because of problems associated with drug residues in animal products and increased bacterial resistance. The immunization of chickens with specific antigens is a promising strategy for generating specific antibodies that can target a wide range of antibiotic-resistant bacteria and can be used as an alternative to antibiotics. Immunoglobulin Y (IgY) antibodies in a polyclonal antibody (pAb) format, when administered orally, modulate the ruminal microbiome and maintain animal health and performance; however, there are concerns pertaining to protein impurities and biotin concentrations in the samples.

The Performance and Metabolism of Dairy Cows Receiving an Ultra-Diluted Complex in the Diet during the Transition Period and Early Lactation.

This study evaluated the effects of feeding an ultra-diluted complex to dairy cows during the transition period and early lactation. Thirty multiparous pregnant dairy cows were blocked and randomly assigned to either a placebo control (CON) group or ultra-diluted complex (UD) group. The CON group received a placebo (basal diet + 40 g/cow/day of expanded silicate), while the UD group received the ultra-diluted complex (basal diet + 40 g/cow/day of PeriParto Transição-RealH, composed of ultra-diluted substances + vehicle: expanded silicate).

Soybean Yield and Nutrition Grown on the Straw of Grain Sorghum Inoculated with and Intercropped with BRS Paiaguás Grass.

The adoption of diversified agricultural systems that employ integrated cultural practices appears to be the way to sustainably intensify tropical agriculture. Our objectives were to evaluate the dry matter (DM) accumulation of sorghum inoculated with , with or without a nitrogen fertilization split, intercropped with palisade grass ( cv. BRS Paiaguás), and how these practices influenced the nutrition and development of soybean in succession.

Spatial distribution and temporal trends of butyltin compounds (TBT, DBT & MBT) in short sediment cores of the SW Portuguese Shelf (western Iberian Margin, NE Atlantic).

Spatial patterns and temporal trends of the butyltin compounds tributyltin (TBT), dibutyltin (DBT), and monobutyltin (MBT) were investigated in a set of sediment samples collected along the SW Portuguese continental shelf. This region did not reach the Good Environmental Status (GES) in accordance with the Marine Strategy Framework Directive (MSFD) during a first evaluation carried out in 2012. Overall, MBT and DBT were the predominant organotin species detected, but high concentrations of TBT were found in and around disposal sites for dredge sludge derived from the dredging in navigation channels, harbours, and shipyard facilities of the Tagus and Sado estuaries.

Methadone Induction for a Patient With Precipitated Withdrawal in the Emergency Department: A Case Report.

In the era of illicit fentanyl, reports on difficulties with buprenorphine inductions for patients with opioid use disorder are emerging. Methadone is the only other approved medication treatment with efficacy similar to buprenorphine but without risks of precipitated withdrawal. Unfortunately, outpatient methadone inductions can take days to weeks to complete, due in part to regulations that limit administration to opioid treatment programs.

Strength and Bioelectrical Activity of the Pelvic Floor Muscles and Sexual Function in Women with and without Stress Urinary Incontinence: An Observational Cross-Sectional Study.

Stress urinary incontinence (SUI) results from an increase in intravesical pressure, which exceeds the pressure at which the urethra remains closed. Symptoms cause social and sexual intercourse discomfort directly or indirectly, which affect health-related quality of life and are associated with pelvic floor muscle (PFM) dysfunction. We aimed to verify the variation in strength and PFM bioelectrical activity and sexual function in women with SUI.

Influence of the Neuroprotective Properties of Quercetin on Regeneration and Functional Recovery of the Nervous System.

Quercetin is a dietary flavonoid present in vegetables, fruits, and beverages, such as onions, apples, broccoli, berries, citrus fruits, tea, and red wine. Flavonoids have antioxidant and anti-inflammatory effects, acting in the prevention of several diseases. Quercetin also has neuroprotective properties and may exert a beneficial effect on nervous tissue.

Racial and ethnic disparities in emergency department-initiated buprenorphine across five health care systems.

Background: Opioid overdose deaths have disproportionately impacted Black and Hispanic populations, in part due to disparities in treatment access. Emergency departments (EDs) serve as a resource for patients with opioid use disorder (OUD), many of whom have difficulty accessing outpatient addiction programs. However, inequities in ED treatment for OUD remain poorly understood.

Tissue Bioengineering with Fibrin Scaffolds and Deproteinized Bone Matrix Associated or Not with the Transoperative Laser Photobiomodulation Protocol.

Extending the range of use of the heterologous fibrin biopolymer, this pre-clinical study showed a new proportionality of its components directed to the formation of scaffold with a lower density of the resulting mesh to facilitate the infiltration of bone cells, and combined with therapy by laser photobiomodulation, in order to accelerate the repair process and decrease the morphofunctional recovery time. Thus, a transoperative protocol of laser photobiomodulation (L) was evaluated in critical bone defects filled with deproteinized bovine bone particles (P) associated with heterologous fibrin biopolymer (HF). The groups were: BC (blood clot + laser); HF; HF; PHF (P+HF); PHF (P+HF+L).

Sexual Function, Physical Activity, Mean Amplitudes and Maximal Voluntary Contraction of Pelvic Floor Muscles Are Related to Handgrip Strength: A Cross-Sectional Study.

Pelvic floor musculature assessment methods are generally invasive, subjective, and technologically expensive. Therefore, there is a need to identify other methods that can predict changes in the function of these muscles. This study aimed to verify whether the levels of strength and myoelectric activity of pelvic floor muscles (PFM) can be related to handgrip strength (HGS), to ensure faster and earlier identification of possible dysfunctions of this musculature.

Use of Photobiomodulation Combined with Fibrin Sealant and Bone Substitute Improving the Bone Repair of Critical Defects.

In this preclinical protocol, an adjunct method is used in an attempt to overcome the limitations of conventional therapeutic approaches applied to bone repair of large bone defects filled with scaffolds. Thus, we evaluate the effects of photobiomodulation therapy (PBMT) on the bone repair process on defects filled with demineralized bovine bone (B) and fibrin sealant (T). The groups were BC (blood clot), BT (B + T), BCP (BC + PBMT), and BTP (B + T + PBMT).
