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.

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).

Article Synopsis
  • The article investigates dynapenic abdominal obesity (DAO) in older adults in Macapa, Brazil, through a study of 382 participants.
  • DAO was identified as having low handgrip strength and increased abdominal circumference, with a prevalence of 10.73% among the subjects.
  • The study found that gait speed was a significant predictor of DAO, highlighting its potential as a key indicator for health management in this population.

Background: The aim of this study was to assess the volumetric stability and bone formation in grafts with Bio-Oss and autogenous bone at different proportions in rabbit calvaria. . Ten rabbits received four titanium cylinders in their calvaria and randomly divided into the following groups: Group I: Bio-Oss (100%), Group II: Bio-Oss (75%) + autogenous bone (25%), Group III: Bio-Oss (50%) + autogenous bone (50%), and Group IV: autogenous bone (100%).

Objective: To analyze the performance of a phonatory deviation diagram (PDD) in discriminating the presence and severity of voice deviation and the predominant voice quality of synthesized voices.

Method: A speech-language pathologist performed the auditory-perceptual analysis of the synthesized voice (n = 871). The PDD distribution of voice signals was analyzed according to area, quadrant, shape, and density.

Parasites of the Leishmania genus are the causative agents of leishmaniasis in humans, a disease that affects more than 12 million people worldwide. In this study was evaluated in vitro leishmanicidal activity of 2-N,N'-dialkylamino-1,4-naphthoquinone derivatives, covering a series of fourteen 2-N-morpholino-, 2-N-thiomorpholino, 2-N-piperidino, 2-N-(N-methyl)-piperazino naphthoquinones (1a-n) derived from nor-lapachol and lawsone, belong to some other di-alkyaminoderivatives. At the cytotoxicity assay on peritoneal macrophages, the compounds possessing larger alkyl groups and N-methyl-piperazino moiety (1d, 1h, 1i and 1k), showed toxic effects similar to the standard drug used pentamidine.

Background And Objective: Malnutrition is prevalent in hospitalized patients and causes systemic damage including effects on the respiratory and immune systems, as well as predisposing to infection and increasing postoperative complications and mortality. This study aimed to assess the impact of malnutrition on the rate of postoperative pulmonary complications, respiratory muscle strength and chest wall expansion in patients undergoing elective upper abdominal surgery.

Methods: Seventy-five consecutive candidates for upper abdominal surgery (39 in the malnourished group (MNG) and 36 in the control group (CG)) were enrolled in this prospective controlled cohort study.

An alternative method of magnification for microvascular anastomosis was analyzed using an ordinary video camera and compared with the traditional method under microscope. For this study 20 rats were divided in two groups of 10 each: control group (microscope-assisted [M]) and experimental group (video-assisted [V]). Magnification was accomplished by a surgical microscope in group M, whereas a video system composed of low-cost camera, audiovisual cable, and analogue television in group V.
