Phytochemicals, which are bioactive compounds contained in fruits, vegetables, and teas, have a positive effect on human health by having anti-inflammatory, antioxidant, and anticarcinogenic effects. Several studies have highlighted the ability of bioactive compounds to activate key cellular enzymes associated with important signaling pathways related to cell division and proliferation, as well as their role in inflammatory and immunological responses. Some phytochemicals are associated with increased proliferation, differentiation, and expression of markers related to osteogenesis, bone formation, and mineralization by activating various signaling pathways.

Leishmaniasis is a neglected tropical disease caused by a protozoan of the genus Leishmania, which has visceral and cutaneous forms. The symptoms of leishmaniasis include high fever and weakness, and the cutaneous infection also causes lesions under the skin. The drugs used to treat leishmaniasis have become less effective due to the resistance mechanisms of the protozoa.

The South American Transcontinental Drainage Divide (TDD) is roughly oriented NE-SW from its Atlantic termination in SE Brazil to its NW termination in the limits between the southwestern edges of the Amazon Craton and the Andean Foreland. Based on a weak spatial coincidence with 90 - 70 Ma igneous intrusions, the origin and stability of the TDD have been attributed to intraplate magmatic activity. Using geomorphic analysis of drainage divides, we infer an overall southward migration of the TDD, even in areas with constrained uplift associated with intrusions.

The iliotibial band originates from the iliac crest and the hip joint capsule, extending along the entire lateral surface until it inserts onto tuberculum anterolateralis tibiae on the anterolateral tibia. It acts as an agonist of the anterior cruciate ligament. In short, the iliotibial band primarily contributes to the lateral stabilization of the knee joint.

Hemosporidians are intracellular pathogens that infect a range of endothermic and ectothermic hosts and are transmitted by dipteran vectors. These parasites are grouped into four families: Haemoproteidae, Plasmodiidae, Leucocytozoidae, and Garniidae, with the genera Haemoproteus, Plasmodium, and Leucocytozoon being the most common in birds. Therefore, the objectives of this study were to detect the infection frequency of hemosporidians and to perform hematological and biochemical analyses in free-living turkey vultures (Cathartes aura) in the Amazon biome, Brazil.

Bioassays and Cellular Dynamics Lab, Department of Chemical and Biological Sciences, Institute of Biosciences, UNESP: São Paulo State University, São Paulo, Brazil.

Calcium phosphates, notably monetite, are valued biomaterials for bone applications owing to their osteogenic properties and rapid uptake by bone cells. This study investigates the enhancement of these properties through Cobalt doping, which is known to induce hypoxia and promote bone cell differentiation. Heat treatments at 700°C, 900°C, and 1050°C are applied to both monetite and Cobalt-doped monetite, facilitating the development of purer, more crystalline phases with varied particle sizes and optimized cellular responses.

Freshwater ecosystems under the influence of human activities are subject to multiple environmental stressors that lead to biodiversity loss and habitat modification. In recent years, various organisms have been used as bioindicators to detect environmental changes by their ability to perceive changes in community attributes. A good example is the semiaquatic bugs (Hemiptera, infra order Gerromorpha) that act as predators and are sensitive to subtle changes in environmental conditions.
