Artemisinin-based combination therapies are the frontline treatment of Plasmodium falciparum malaria. The circulation of falsified and substandard artemisinin-based antimalarials in Southeast Asia has been a major predicament for the malaria elimination campaign. To provide an update of this situation, we purchased 153 artemisinin-containing antimalarials, as convenience samples, in private drug stores from different regions of Myanmar. The quality of these drugs in terms of their artemisinin derivative content was tested using specific dipsticks for these artemisinin derivatives, as point-of-care devices...

In April, 2017, the United Nations (UN) announced that it will withdraw peacekeeping soldiers from Haiti after 13 years there.(1) Known by its French acronym MINUSTAH, the mission has been controversial in security terms, but in terms of public health, it is not controversial to state that peacekeepers will be leaving a heavy mark on the health of Haitians. The UN has acknowledged that peacekeeping soldiers were responsible for both the introduction of cholera (which sparked a nationwide epidemic) and the sexual abuse and exploitation of Haitians, including minors...

The fibrous skeleton is concentrated at the base of the ventricular mass. It provides electrical insulation at the atrioventricular level and fibrous continuity for the leaflets of the mitral, aortic, and tricuspid valves. Its components include the fibrous trigones, the fibrous area of aortic-mitral continuity, the subvalvar collar of the mitral valve, the membranous septum, the interleaflet triangles, the tendon of Todaro, and likely the conus ligament. The majority of the mitral annulus is fibrous, but the only true fibrous part of the tricuspid annulus is where the valvar leaflets are attached to the central fibrous body...

Melatonin (MEL) has promising medicinal value as an anticancer agent in a variety of malignancies, but there are difficulties in achieving a therapeutic dose due to its short half-life, low bioavailability, poor solubility and extensive first-pass metabolism. In this study chitosan/tripolyphosphate (TPP) nanoparticles were prepared by an ionic gelation method to overcome the therapeutic challenges of melatonin and to improve its anticancer efficacy. Characterization of the melatonin-loaded chitosan (MEL-CS) nanoformulation was performed using transmission and scanning electron microscopies, dynamic light scattering, Fourier transform infrared spectroscopy, Raman spectroscopy and x-ray diffraction...

The studies presented were designed to highlight the impact of pancreatic enzymes on glycemic control and insulin response. Blood glucose and plasma insulin levels were monitored after intravenous, oral or direct gut glucose tolerance tests (GTT) in 6 pigs with an intact gastrointestinal tract and in 12 pigs following duodenal-jejunal bypass (DJB) surgery. In the intact pigs, pancreatic enzymes (Creon®) given orally 1 h prior to the GTT, lowered the blood glucose levels during the oral and meal GTT and reduced the plasma insulin response during the intravenous and meal GTT...

Escape behaviors in peneid shrimp are mediated by large myelinated medial giant fibers which course from the brain to the last abdominal ganglion in the ventral nerve cord. In each abdominal segment the medial giant axons make synaptic connections with paired myelinated giant motor axons that excite the abdominal deep flexor muscles and drive the tailflips that constitute the escape behavior. I examined 1) anatomical features of the abdominal motor giant fibers and 2) electrical properties of both the medial giants and motor giants in the pink shrimp, Farfantepenaeus duoarum...

The challenge of controlling algal blooms and reusing algal biomass remain unsolved worldwide. We introduce a facile method to reuse Nannochloropsis biocrude oil (NBO) for the synthesis of nitrogen and sulfur co-doped carbon dots (N-S-C-dots). N-S-C-dots can pass through the heavily thickened wall of mature Arabidopsis thaliana (A. thaliana) guard cells because of high solubility and excellent biocompatibility. N-S-C-dots exhibit multicolor luminescence and could effectively reduce the interference of autofluorescence in plant cells by changing filters...

Intestinal cytochrome P450 (CYP) enzymes play key role in the first pass metabolism of orally ingested xenobiotics, providing a primary metabolic barrier, being of special importance in maintaining animal health and production. This study was aimed to investigate how intestinal drug-metabolizing CYPs can be modulated by nutritional factors in broiler chicken. We investigated the effects of the natural growth promoter (n-)butyrate of different origin (feed supplementation of protected or non-protected forms and/or inducing caecal microbial production by supporting higher level of dietary non-starch polysaccharides [NSP]) on the activity of duodenal CYPs...

Pyrrolizidine alkaloids (PAs) are a type of natural hepatotoxic compounds. Monocrotaline (MCT), belongs to PAs, is a main compound distributed in medicinal herb Crotalaria ferruginea Grah. ex Benth. This study aims to identify the potential biological signaling pathway associated with MCT-induced liver injury by analyzing the integrative altered hepatic microRNA (miRNA) and mRNA expression profile. C57BL/6 mice were orally given with MCT (270, 330mg/kg). Serum alanine/aspartate aminotransferase (ALT/AST) activity, total bilirubin (TBil) amount and liver histological evaluation showed the liver injury induced by MCT...

Theory of mind (ToM) gradually develops during the preschool years. Measures of ToM usually target visual experience, but auditory experiences also provide valuable social information. Given differences between the visual and auditory modalities (e.g., sights persist, sounds fade) and the important role environmental input plays in social-cognitive development, we asked whether modality might influence the progression of ToM development. The current study expands Wellman and Liu's ToM scale (2004) by testing 66 preschoolers using five standard visual ToM tasks and five newly crafted auditory ToM tasks...

In the last few years, interest in circular synthetic aperture radar (CSAR) acquisitions has arisen as a consequence of the potential achievement of three-dimensional (3D) reconstructions over 360° azimuth angle variation. In real-world scenarios full 3D reconstructions of arbitrary targets need multi-pass data, which makes the processing complex, money-consuming and time-expending. In this paper, we propose a processing strategy for the 3D reconstruction of vehicle, which can avoid using multi-pass data by introducing a priori information of vehicle's shape...

The objective of this paper is to examine the implementation of Colombia's tobacco control law. Methods involved are triangulated government legislation, news sources, and interviews with policy-makers and health advocates in Colombia. Colombia, a middle-income country, passed a tobacco control law in 2009 that included a prohibition on tobacco advertising, promotion, and sponsorship; and required pictorial health warning labels, ingredients disclosure, and a prohibition on individual cigarette sales. Tobacco companies challenged the implementation through litigation, tested government enforcement of advertising provisions and regulations on ingredients disclosure, and lobbied local governments to deprioritise policy responses to single cigarette sales...

A conserved AAA+ ATPase, called Cdc48 in yeast and p97 or VCP in metazoans, plays an essential role in many cellular processes by segregating polyubiquitinated proteins from complexes or membranes. For example, in endoplasmic reticulum (ER)-associated protein degradation (ERAD), Cdc48/p97 pulls polyubiquitinated, misfolded proteins out of the ER and transfers them to the proteasome. Cdc48/p97 consists of an N-terminal domain and two ATPase domains (D1 and D2). Six Cdc48 monomers form a double-ring structure surrounding a central pore...
