Evaluation of the Antioxidant Properties and Biological Effects of a Novel Combined Barberry Root-Propolis Extract on HEK293T Cells.

The health benefits of honeybee products and herbs are well known, and their appropriate combination may enhance their biological efficacy. This study investigated the biological properties of a combined barberry root and propolis extract (PBE) in comparison to a propolis extract (PE), a barberry root extract (BE), and pure berberine (BN). The antioxidant properties were evaluated using DPPH and FRAP methods and total phenolic contents (TPC) were assessed by the Folin-Ciocalteu method.

Prevalence of spp. in Lithuanian Wild Boars ().

is a bacteria responsible for a widespread zoonosis that affects both humans and animals. Leptospirosis is a challenging pathology to diagnose and treat since its signs are unspecific and symptoms vary greatly. The disease seems to be highly prevalent in environments where reservoir animals such as rats and small mammals are common.

Impact of eggshell membrane on metabolism and cell adhesion in oxidatively stressed canine chondrocytes.

Eggshell membrane (ESM) is a rich source of bioactive compounds, including proteins, peptides, and antioxidants, contributing to its potential therapeutic benefits. These natural antioxidants might help neutralize reactive oxygen species (ROS) and modulate inflammatory responses, which are often linked with chondrocyte damage in osteoarthritis. In this study, we investigated the functional effects of ESM proteins on HO-induced oxidative stress in a neonatal canine chondrocytes.

This prospective randomised study compared two balanced crystalloid solutions regarding their effect on acid-base status, electrolytes and LAC concentrations in dehydrated cats after intravenous fluid therapy.

Assessment of Extracellular Particles Directly in Diluted Plasma and Blood by Interferometric Light Microscopy. A Study of 613 Human and 163 Canine Samples.

Extracellular nanoparticles (EPs) are a subject of increasing interest for their biological role as mediators in cell-cell communication; however, their harvesting and assessment from bodily fluids are challenging, as processing can significantly affect samples. With the aim of minimizing processing artifacts, we assessed the number density () and hydrodynamic diameter () of EPs directly in diluted plasma and blood using the following recently developed technique: interferometric light microscopy (ILM). We analyzed 613 blood and plasma samples from human patients with inflammatory bowel disease (IBD), collected in trisodium citrate and ethylenediaminetetraacetic acid (EDTA) anticoagulants, and 163 blood and plasma samples from canine patients with brachycephalic obstructive airway syndrome (BOAS).

Thirty cats were included in the study.

Effect of Gentamicin-Loaded Calcium Phosphate Coating and Polymeric Coating on the Degradation Properties of Biodegradable Iron-Based Biomaterials.

In the past decades, iron has been one of the intensively studied biodegradable metals due to its suitable mechanical properties, but it suffers from slow degradation in a physiological environment and low bioactivity. In this work, the beneficial properties of ceramic and polymer coatings were merged to enhance the corrosion properties and biological compatibility of Fe-based biomaterials. A new bilayer coating for Fe-based biomaterials that speeds up degradation while offering controlled, localized drug release to prevent infections was prepared.

Complement Evasion Protects FCoV from Virus Clearance Within Prototypic FIP Lesions.

Feline infectious peritonitis (FIP) is a fatal disease in cats caused by infection with feline coronavirus (FCoV). Despite severe inflammatory changes, defense mechanisms fail to achieve virus clearance. Some studies focused on various immune evasion mechanisms, but none of these studies elucidated the inefficacy of the complement system, which is one major player in FIP-associated immune pathogenesis.

A comparison of cognitive decline in aged mice and mice treated with aftin-4.

Dementia, especially Alzheimer's disease, presents a major clinical challenge, and researchers are still searching for an optimal animal model. To address this gap, we compared male and ovariectomized female C57BL/6 mice treated with 30 mg/kg aftin-4, which induces neurodegeneration, with naturally aged (15-16 months old) mice not treated with aftin-4. We performed a series of behavioral tests; measured postmortem plasma β-amyloid levels (Aβ1-40 and Aβ1-42) and the levels of the oxidative stress indicators glutathione peroxidase (GPx), superoxide dismutase (SOD) and malondialdehyde (MDA); and evaluated astrocytic reactivity in the brain using glial fibrillary acid protein (GFAP) levels.
