Article Synopsis
  • - The study aimed to evaluate how stable a hip resurfacing prosthesis is in dog cadaver femurs using various biomechanical tests.
  • - Twenty canine femurs were tested, with one femur receiving the prosthesis and the other remaining intact; the tests measured load capacity and displacement during stress.
  • - Results showed that the prosthesis had lower maximum load and load at collapse values compared to intact femurs, but similar behavior in terms of displacement and stiffness, indicating some limitations in the prosthesis's performance.

Background: Non-syndromic orofacial cleft (NSOC) is a complex phenotype, involving multiple genetic and environmental factors. Association studies exploring the genetic susceptibility to this prevalent oral malformation show variability of results in different populations. Using a candidate gene approach, we aimed to verify the role of four single-nucleotide polymorphisms (SNPs) in the susceptibility to NSOC in Portuguese patients.

A four-month-old domestic shorthair cat with no clinical signs was referred for further examination of a heart murmur. An echocardiogram revealed marked right atrial dilation, extending into the left hemithorax. Computed tomography angiography was conducted to investigate further, which revealed a balloon-shaped, contrast-filled cavity on the cranial and left side of the chest that connected to the right atrium through a narrow passage.

Aims: In rats, stress-induced hyperthermia caused by social interaction depends on brown adipose tissue (BAT) thermogenesis and peripheral vasoconstriction. However, the peripheral mechanisms responsible for regulating the level of hyperthermia during social stress are still unknown. The transient receptor potential vanilloid 1 (TRPV1) subfamily, expressed in sensory and visceral neurons, can serve as a thermoreceptor.

Topical preparations of hydrocortisone can be used for the anti-inflammatory treatment of the female genital area. Although the drug is a low-strength corticosteroid, systemic absorption and distribution of the drug are the most common safety risks associated with this therapy. In the current investigation, we elucidate the physicochemical properties of lipid-based drug carrier systems that govern the local bioavailability of hydrocortisone for intravaginal administration.

There is ongoing and rapid advancement in approaches to modelling the fate of exhaled particles in different environments relevant to disease transmission. It is important that models are verified by comparison with each other using a common set of input parameters to ensure that model differences can be interpreted in terms of model physics rather than unspecified differences in model input parameters. In this paper, we define parameters necessary for such benchmarking of models of airborne particles exhaled by humans and transported in the environment during breathing and speaking.

Although Brazilian livestock is considered one of the most productive in the world, the losses caused by parasites still greatly limit these activities and its incorrect control through traditional synthetic chemicals has caused problems such as parasitic resistance. The present study evaluated the anthelmintic and acaricidal action of ethanolic extract (EE) and essential oil (OE) obtained from Achyrocline satureioides inflorescences against an endo and an ectoparasite of great importance in sheep and cattle. The action against Haemonchus contortus was evaluated by the Larval Development Test (LDT) and the Egg Hatching Test (EHT), while the acaricidal potential against Rhipicephalus (Boophilus) microplus was evaluated by the Adult Immersion Test (AIT) and Larval Package Test (LPT).

In this paper, the statistical distributions of the position and the size of the evaporating droplets after a cough are evaluated, thus characterizing the inherent stochasticity of respiratory releases due to turbulence. For that, ten independent realizations of a cough with realistic initial conditions and in a room at 20 °C and 40% relative humidity were performed with large eddy simulations and Lagrangian tracking of the liquid phase. It was found that although turbulence decreases far from the emitter, it results in large variations in the spatial distribution of the droplets.
