1. Avaliação da biocompatibilidade de magnetolipossomas à base de nanopartículas de maghemita
Nanobiotechnology represents an emerging and promising research field. Nanostructured materials, such as magnetic fluids and magnetoliposomes (MLs), have been proposed for drug-delivery systems and thermal-based cancer therapy amongst other several applications in biomedicine. In particular, MLs are physiologically stable structures, consisting of magnetic n

2. Uso de uréia de liberação lenta em suplementos protéico-energéticos fornecidos a bovinos recebendo forragens de baixa qualidade / Slow-release urea in proteic-energetic supplements fed to beef cattle receiving low quality forage
The effects of traditional urea replacement for slow-release urea (SRU) and of two levels of non-protein nitrogen (NPN) in crude protein (CP) fraction of supplements fed at 0.6% of body weight (BW) to Nellore steers consuming Brachiaria brizantha hay (ad libitum) were evaluated. Eight animals, with 374,40kg (± 42Kg) of BW and fitted with rumen cannula

3. Liposomal encapsulation of foscarnet protects against hypocalcemia induced by free foscarnet.
Hypocalcemia and an increase in creatinine level are the most important serious effects associated with foscarnet (PFA) therapy. In an animal model, we have explored the potential protective role of liposome-encapsulated foscarnet (LE-PFA) on these metabolic abnormalities. PFA administered as one bolus injection (0.5 or 1.0 g/kg) caused significant rapid dec

4. Therapeutic evaluation of free and liposome-encapsulated amphotericin B in the treatment of systemic candidiasis in mice.
Various doses of amphotericin B encapsulated into unilamellar vesicles of 0.1 micron diameter (lip-AMB) (1.0 to 20.0 mg/kg of body weight) were compared with free amphotericin B (AMB) (0.5 to 2.0 mg/kg of body weight) in a murine model of disseminated candidiasis. CD2F1 mice injected intravenously with 3 x 10(5) Candida albicans cells were treated with eithe

5. In vivo biodistribution of a radiolabeled blood substitute: 99mTc-labeled liposome-encapsulated hemoglobin in an anesthetized rabbit.
Liposome-encapsulated hemoglobin (LEH) is an erythrocyte substitute that is a potential resuscitative fluid for the in vivo delivery of oxygen. We have noninvasively imaged radiolabeled LEH in vivo with technetium-99m (99mTc) to study the biodistribution in an anesthetized rabbit. Rabbits (2.5 kg, n = 8) were infused with 30 ml of LEH (200 mg of phospholipid
