The mitochondriotropic antioxidants AntiOxBEN and AntiOxCIN are structurally-similar but differentially alter energy homeostasis in human skin fibroblasts.

Mitochondrial dysfunction and increased reactive oxygen species (ROS) generation play an import role in different human pathologies. In this context, mitochondrial targeting of potentially protective antioxidants by their coupling to the lipophilic triphenylphosphonium cation (TPP) is widely applied. Employing a six‑carbon (C) linker, we recently demonstrated that mitochondria-targeted phenolic antioxidants derived from gallic acid (AntiOxBEN) and caffeic acid (AntiOxCIN) counterbalance oxidative stress in primary human skin fibroblasts by activating ROS-protective mechanisms.

Macrofouling on marine litter in a Southwest Atlantic urban tropical bay and surrounds.

Rafting is the transport of marine litter by organisms, influenced by substrate characteristics such as degradation, shape, surface orientation, color, and polymer type. This study focuses on rafting in the Southwest Atlantic, characterizing biofouling on different materials across high- and low-energy beaches. Conducted in Guanabara Bay and Niteroi's oceanic beaches, sampling focused on strandlines.

In Vitro Antitumor Effect of Oils Rich in CBD and THC Cannabis Extract in Canine Prostate Carcinoma Cell Lines.

Prostate cancer is one of the leading causes of cancer-related deaths worldwide, even when diagnosed at an early stage in humans and dogs. Dogs have a significant incidence of spontaneous prostate cancer, which is highly similar to human androgen-independent prostate cancer and represents a valuable model for comparative studies. Cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC) are the two main cannabinoids extracted from and have demonstrated antiproliferative and anti-invasive properties in different tumor types.

Clinical and pathological findings of Africanized bee (Apis mellifera) envenomation in horses.

Africanized crossbred bees (Apis mellifera) originated in Brazil in 1957, and since then, the number of accidents involving humans and animals has significantly increased. Although they are considered clinical emergencies, there are few reports describing the clinical and pathological aspects of bee envenomation in horses. In this context, this report aims to describe the clinical and pathological features of bee toxicity after massive bee envenomation in three horses.

Portuguese version of the Literacy Independent Cognitive Assessment (LICA) instrument in the evaluation of individuals aged 50 years or older with Itabaianinha syndrome.

Objectives: Individuals with congenital isolated growth hormone deficiency (IGHD) in Northeastern Brazil have a normal lifespan with a prolonged healthspan. We hypothesize that their increased healthspan is accompanied by a reduced cognitive decline during aging. We have recently shown that these individuals have a similar total cognitive function and better attention and executive function than controls.
