Penetrating captive bolt (PCB) is widely used for stunning and on-farm dispatch of livestock, yet its efficacy can vary, with the potential for animal welfare compromise. This study investigated the pathophysiology of PCB-induced trauma in horned and polled sheep (), focusing on factors contributing to incomplete concussion. Thirty-seven ( = 18 horned Scottish blackface and = 19 polled North Country mule) mature ewes (aged 4-10 years) were shot with PCB with varying cartridge power and PCB modifications, followed by clinical assessment and post-mortem analysis using magnetic resonance imagining (MRI) and gross pathology.

Campylobacter is a major cause of foodborne gastroenteritis worldwide, with the mishandling of contaminated chicken meat among the main pathways for human infection. Granted the disease burden due to this pathogen, systematic assessments of its potential impact are necessary. The aims of this study were to evaluate both presence and load of Campylobacter in chicken meat sold in traditional markets, assess risk factors related with the infrastructure and hygienic conditions of market stalls, and evaluate control strategies for campylobacteriosis in Peru through a quantitative microbiological risk assessment (QMRA), a data-driven, systematic approach to quantitatively assess risks by integrating empirical contamination levels, microbial behavior, and consumer exposure.

This review explores the advancements in additive manufacturing (AM) of biodegradable iron (Fe) and zinc (Zn) alloys, focusing on their potential for medical implants, particularly in vascular and bone applications. Fe alloys are noted for their superior mechanical properties and biocompatibility but exhibit a slow corrosion rate, limiting their biodegradability. Strategies such as alloying with manganese (Mn) and optimizing microstructure via laser powder bed fusion (LPBF) have been employed to increase Fe's corrosion rate and mechanical performance.

Due to its inbuilt ability to release biocompatible materials encapsulating living cells in a predefined location, 3D bioprinting is a promising technique for regenerating patient-specific tissues and organs. Among various 3D bioprinting techniques, extrusion-based 3D bioprinting ensures a higher percentage of cell release, ensuring suitable external and internal scaffold architectures. Scaffold architecture is mainly defined by filament geometry and width.

In Alzheimer's disease (AD), the propagation and spreading of CNS tau pathology closely correlates with cognitive decline, positioning tau as an attractive therapeutic target. Amyloid beta (Aβ) has been strongly implicated in driving tau spread, whereas primary tauopathies such as primary age-related tauopathy (PART)-which lack Aβ pathology-exhibit limited tau spread and minimal-to-no cognitive decline. Emerging evidence converges on a trans-synaptic mechanism of tau spread, facilitated by the transfer of misfolded tau aggregates (e.

Background: Delayed cerebral injury (DCI) after aneurysmal subarachnoid hemorrhage (SAH) is a preventable injury that would improve patient outcomes if an effective treatment can be developed. The most common long-term disability in patients with SAH is cognitive dysfunction. Contrary to the common theory that damage from DCI originates solely from ischemia caused by cerebral vasospasm, inflammation has been shown to be an important independent mediator of DCI.

Background: Patients with microsatellite-instability-high (MSI-H) or mismatch-repair-deficient (dMMR) metastatic colorectal cancer have poor outcomes with standard chemotherapy with or without targeted therapies. Nivolumab plus ipilimumab has shown clinical benefit in nonrandomized studies of MSI-H or dMMR metastatic colorectal cancer.

Methods: In this phase 3 open-label trial, we randomly assigned patients with unresectable or metastatic colorectal cancer and MSI-H or dMMR status according to local testing to receive, in a 2:2:1 ratio, nivolumab plus ipilimumab, nivolumab alone, or chemotherapy with or without targeted therapies.

Eco-friendly materials must replace pure synthetic materials to protect the environment and improve human welfare. This study uses a blow room-integrated carding machine to create a filmy web by properly mixing modified jute and polyester fibers. Jute-polyester fiber blended carded webs have been utilized to produce jute-based hybrid nonwoven fabrics (JHNFs), which are subsequently given an antibacterial treatment by spraying a solution of silver nitrate, ethanol, and ammonia.

Background: This study aims to compare the effectiveness of the long-arm cast (LAC) and the single sugar-tong splint (SSTS) in the non-operative treatment of distal radius fractures in the geriatric population.

Methods: Patients consulted at the Orthopedics and Traumatology Department within the Emergency Department (ED) were reviewed through the electronic archives of a tertiary university hospital over a five-year period. The study included patients aged 65 years and older with a distal radius fracture who required reduction, had successful closed reduction, and had at least six weeks of X-ray follow-up.

Prospective university students experience substantial academic stressors and psychological vulnerabilities, yet their mental health literacy (MHL) remains inadequately explored. This study investigates four dimensions of MHL - help-seeking behaviors, stigma, knowledge about mental health and understanding of mental illnesses. Besides, Geographic Information System (GIS) techniques are employed to analyze spatial disparities in MHL, which is the first in the context of MHL research.

Multiple transboundary animal diseases (TADs) circulate in Plateau State, Nigeria, where livestock keeping is common and contributes to both the physical and socio-economic well-being of a large proportion of the population. In this study, we explored the potential for environmental sampling to detect viruses causing TADs circulating in the region. Electrostatic dust cloths were used to swab areas of the environment likely to have contact with secretions and excretions from infected animals.

  • Pneumothorax (PTX) is a significant concern in trauma centers, with up to 20% of patients presenting with it, and about 5% of combat casualties dying from tension PTX (tPTX), making rapid diagnosis and treatment critical.
  • The Donaldson Decompression Needle (DDN) is designed to improve safety during decompression by preventing over-insertion and reducing the risk of causing new injuries while still effectively alleviating pressure in the chest.
  • A study comparing the DDN to a standard needle found that while setup times were similar, the DDN had a significantly longer decompression time, highlighting a trade-off between safety and speed in handling PTX.

Alkali metal anodes paired with solid ion conductors offer promising avenues for enhancing battery energy density and safety. To facilitate rapid ion transport crucial for fast charging and discharging of batteries, it is essential to understand the behavior of point defects in these conductors. In this study, we investigate the heterogeneity of defect distribution in two prototypical solid ion conductors, LiOCl and LiPON (LiPON), by quantifying the defect formation energy (DFE) as a function of distance from the surface and interface through first-principles simulations.

Introduction: Previous studies have demonstrated the benefits of tranexamic acid (TXA) administration in combination with packed red blood cell (PRBC) transfusion in trauma patients without increasing the risk of venous thromboembolism (VTE). However, the effect of TXA in combination with whole blood (WB) has not been studied. Injury, abbreviated injury severity scores (ISS and AIS) and the need for blood transfusions are historically associated with VTE.
