Effects of nanocapsules containing lumefantrine and artemether in an experimental model of cerebral malaria.

Background: Malaria, a tropical neglected disease, imposes a significant burden on global health, leading to the loss of thousands of lives annually. Its gold standard treatment is a combination therapy of lumefantrine (LUM) and artemether (ART). Nanotechnology holds significant potential for improving drug bioavailability and potency while reducing adverse effects.

Effects of Extended Treatment with Liposomes on Metabolic Parameters of Obese Rats.

(), popularly known as "almacega" or "white pitch", is widely used in folk medicine due to its antioxidant, anti-inflammatory and healing properties, attributed to its richness in flavonoids and terpenes. Therefore, this study aimed to evaluate the effects of treatment for 28 days with liposomes containing leaf extract in obese animals. Male Wistar rats, subjected to a hypercaloric diet for 8 weeks to induce obesity (hypercaloric chow and water enriched with 30% sucrose, ad libitum), were treated with the plant formulation (1 mg kgday, via gavage) for 28 days.

Effect of Liposomal (Alb.) March Extract in the Treatment of Obesity Induced by High-Calorie Diet.

Obesity, a chronic disease, resulted from excessive consumption of high-calorie foods, leading to an energy imbalance. () was used in folk medicine for its analgesic, anti-inflammatory, and healing properties. The association of the extract from with nanotechnology was innovative for combining high technology with active ingredients that are easily accessible in the Amazon region.

Potential of nanoformulations in malaria treatment.

Malaria is caused by the protozoan and affects millions of people worldwide. Its clinical form ranges from asymptomatic to potentially fatal and severe. Current treatments include single drugs such as chloroquine, lumefantrine, primaquine, or in combination with artemisinin or its derivatives.

Artemether-loaded polymeric lipid-core nanocapsules reduce cell viability and alter the antioxidant status of U-87 MG cells.

Glioblastomas are tumors that present a high mortality rate. Artemether (ART) is a lactone with antitumor properties, demonstrating low bioavailability and water solubility. In the present study, we developed lipid-core nanocapsules (LNC) containing pequi oil ( Cambess) as the oily core for ART-loaded LNCs (LNC) and evaluated their effect on human glioblastoma cells (U-87 MG).

Pequi ( Cambess)-Loaded Nanoemulsion, Orally Delivered, Modulates Inflammation in LPS-Induced Acute Lung Injury in Mice.

Pequi is a Brazilian fruit used in folk medicine for pulmonary diseases treatment, but its oil presents bioavailability limitations. The use of nanocarriers can overcome this limitation. We developed nanoemulsions containing pequi oil (pequi-NE) and evaluated their effects in a lipopolysaccharide (LPS)-induced lung injury model.

Healing of dermal wounds property of Caryocar brasiliense oil loaded polymeric lipid-core nanocapsules: formulation and in vivo evaluation.

Cutaneous lesions lead to complications in patients, since they may be recurrent and also represent risk of progression to infection and/or amputation. Therefore, effective, protective, and topical treatments of easy application and removal need to be developed to provide effective alternatives to patients. The Caryocar brasiliense Cambess (CBC) presents important pharmacological activities and proved in the healing process.

Encapsulation in lipid-core nanocapsules improves topical treatment with the potent antileishmanial compound CH8.

Cutaneous leishmaniasis (CL) is a neglected parasitic disease conventionally treated by multiple injections with systemically toxic drugs. Aiming at a more acceptable therapy, we developed lipid-core nanocapsules (LNCs) entrapping the potent antileishmanial chalcone (CH8) for topical application. Rhodamine-labeled LNC (Rho-LNC-CH8) was produced for imaging studies.

Acaricidal activity of limonene, limonene oxide and beta-amino alcohol derivatives on Rhipicephalus (Boophilus) microplus.

Limonene, limonene oxide and eight beta-amino alcohol derivatives obtained by synthesis were investigated for the effect on egg hatchability and mortality rates of newly hatched larvae of the cattle tick Rhipicephalus (Boophilus) microplus. At the doses between 10 microg/ml and 2.5 microg/ml all the compounds were highly lethal to the larvae and some of them showed activity at lower concentrations.

Acaricidal activity of the hyacinthacine analogues derived from pyrrolizidine alkaloids on Rhipicephalus (Boophilus) microplus.

This study reports the effect of six hyacinthacine analogues derived from pyrrolizidine alkaloids on egg hatchability and mortality rates of newly hatched larvae of the cattle tick Rhipicephalus (Boophilus) microplus. All the compounds were toxic to the larvae of the ticks and inhibited the eggs hatchability in the higher concentration tested (5 microg/ml). Even in the lowest concentration (0.
