Ultrasonographic computer-assisted quantification of the intraluminal uterine content in female dogs.

In dogs, the characterization of intraluminal uterine contents has been subjectively carried out by the operators. The aims of this study were: 1) To ultrasonographically describe and compare the echogenicity and heterogeneity of the intraluminal uterine contents in bitches using digital analysis; 2) To assess the cytology of the uterine contents; 3) To evaluate the effect of clinical, ultrasonographic, bacteriological and cytological parameters on intraluminal contents echogenicity and heterogeneity. Twenty-one intact, 3-24 kg, 1-12 years of age, female dogs with ultrasonographically detected uterine content were included.

Crystalline silica on the lung-environment interface: Impact on immunity, epithelial cells, and therapeutic perspectives for autoimmunity.

Crystalline silica (the most abundant form of silicon dioxide) is a natural element that is ubiquitous in the Earth's crust. Chronic personal or professional exposure has been implicated in various pathologies, including silicosis and autoimmune diseases since the early 20th century. More recently, a specific pathogenic role for crystalline silica has been identified through its impact on lung epithelial cells as well as immune cells present at this organism barrier.

Flexor Tendon Rupture After a Cat Bite - A Case Report of An Uncommon Sequela.

Introduction: Cat bites are a remarkably common injury seen in the emergency department setting . Due to the morphology of feline teeth and anatomy of the human hand, seemingly innocuous surface bites can seed infections in deeper structures of the hand that can result in adverse outcomes. We report on a case of a rare complication of a flexor tendon rupture that occurred well after the initial treatment of a superficial infection.

When can flexible weak polyelectrolytes be treated as effective rigid objects?

Conformational and ionization equilibria of flexible weak polyelectrolytes (PEs) are, in general, strongly coupled. In this article, we analyze the effect of averaging over (or "contracting") the conformational degrees of freedom so that the original flexible molecule is replaced by an effective rigid object with the same ionization properties. As a result, one obtains the so-called Site Binding (SB) model, much easier to treat both theoretically and computationally, and extensively used to characterize the ionization properties of PE.

Inflammasome-targeted therapy might prevent adverse perinatal outcomes of recurrent chronic intervillositis of unknown etiology.

Chronic histiocytic intervillositis of unknown origin (CHI) is a rare placental disorder associated with adverse pregnancy outcomes, frequent recurrence, and a lack of effective preventive strategies. Recent insights indicate a potential link between CHI-associated inflammatory lesions and the inflammasome pathway, suggesting innovative therapeutic avenues. Here we show a potential role of the inflammasome pathway in CHI through comprehensive transcriptomic analysis of grade 2 or 3 histopathologic CHI samples, paired with placental controls.
