Objectives: To examine and summarize the current literature on the effects of therapeutic plasma exchange on medication levels. Methods: Literature review was performed via searches of the Cochrane Database and PubMed-MEDLINE (1996 to August 2016) looking for all case reports, case series, and human randomized controlled trials involving therapeutic plasma exchange (TPE)-associated drug removal. Results: Approximately 60 peer-reviewed articles were identified with the majority being case reports; no randomized controlled trials were identified...

An unambiguous structural characterization of the water-soluble Aureobasidium pullulans β-(1→3, 1→6)-glucan is yet to be achieved, although this β-(1→3, 1→6)-glucan is expected to exhibit excellent biofunctional properties. Thus, we herein report the elucidation of the primary structure of the A. pullulans β-(1→3, 1→6)-glucan using nuclear magnetic resonance spectroscopy, followed by comparison of the obtained structure with that of schizophyllan (SPG). Structural characterization of the A. pullulans β-(1→3, 1→6)-glucan revealed that the structural units are a β-(1→3)-d-glucan backbone with four β-(1→6)-d-glucosyl side branching units every six residues...

Dextrans synthesised by three Leuconostoc mesenteroides strains, isolated from mammalian milks, were studied and compared with dextrans produced by Lc. mesenteroides and Lactobacillus sakei strains isolated from meat products. Size exclusion chromatography coupled with multiangle laser light scattering detection analysis demonstrated that the dextrans have molecular masses between 1.74×10(8)Da and 4.41×10(8)Da. Rheological analysis of aqueous solutions of the polymer revealed that all had a pseudoplastic behaviour under shear conditions and a random, and flexible, coil structure...

In this study, as-synthesized curdlan sulfate (CRDS) with a flexible random coil chain was selected as a polyanion to construct nanosized polyelectrolyte complexes (PECs) with a polycation, chitosan (CS), via electrostatic interactions. Nanosized PECs were formed simply by mixing CRDS (0.5mg/mL) and CS (0.5mg/mL) at a mass ratio of 2:1 at pH 3.5. The CRDS/CS PECs exhibited a spherical morphology with a Z-average diameter of around 180nm and a zeta potential value of about -38mV. Subsequently, zidovudine (AZT) as a model antiviral drug was successfully encapsulated into the nanosized PECs with a favorable drug loading efficiency...

BACKGROUND: Buruli ulcer (BU), caused by Mycobacterium ulcerans, is increasing in incidence in Victoria, Australia. To improve understanding of disease transmission, we aimed to map the location of BU lesions on the human body. METHODS: Using notification data and clinical records review, we conducted a retrospective observational study of patients diagnosed with BU in Victoria from 1998-2015. We created electronic density maps of lesion locations using spatial analysis software and compared lesion distribution by age, gender, presence of multiple lesions and month of infection...

We for the first time confirmed that the low concentrations of Ag(I) could induce a silver specific aptamer probe (SAP) from a random coil sequence form to G-quadruplex structure. Thereby, a novel highly sensitive fluorescence strategy for silver(I) assay was established. The designed multifunctional SAP could act as a recognition element for Ag(I) and a signal reporter. The use of such a SAP can ultrasensitively and selectively detect Ag(I), giving a detection limit down to 0.64nM. This is much lower than those reported by related literatures...

We have previously shown that incorporation of a second intradomain disulfide linkage into camelid VHH and human VH/VL single-domain antibodies confers increased thermostability. Here, we explored the effects of introducing an additional disulfide linkage, formed between Cys48 and Cys64 (Kabat numbering), into a phage-displayed synthetic human VL library. In comparison to an identical library bearing only the highly conserved Cys23-Cys88 disulfide linkage, the disulfide-stabilized VL library tolerated a similar degree of randomization but retained a higher level of functional diversity after selection with protein L...

Pressures on freshwater biodiversity in Southeast Asia are accelerating yet the status and conservation needs of many of the region's threatened fish species are unclear. This impacts the ability to implement conservation activities and to understand the effects of infrastructure developments and other hydrological changes. We used Local Ecological Knowledge from fishing communities on the Mekong River in the Siphandone waterscape, Lao PDR to estimate mean and mode last capture dates of eight rare or culturally significant fish species in order to provide conservation monitoring baselines...

BACKGROUND: Reactive case detection (RACD) around passively detected malaria cases is a strategy to identify and treat hotspots of malaria transmission. This study investigated the unproven assumption on which this approach is based, that in low transmission settings, infections cluster over small scales. METHODS: A prospective case-control study was conducted between January 2013 and August 2014 in Ohangwena and Omusati regions in north central Namibia. Patients attending health facilities who tested positive by malaria rapid diagnostic test (RDT) (index cases) were traced back to their home...

BACKGROUND: Intestinal iron is a nutritional compound, which is essential for enteric microbiota. We evaluated the hypothesis that polymorphisms which are known modifiers of intestinal iron uptake in adults are associated with necrotizing enterocolitis (NEC) in preterm infants. METHODS: Preterm infants (birth weight below 1,500 grams) were studied. Single nucleotide polymorphisms with known effects on serum iron levels (rs1800562, rs1799945, rs855791) were determined by polymerase chain reaction...

Cannabidiol has recently been proposed as an antipsychotic for schizophrenia. However, its clinical use and safety is controversial. To answer this question, we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We identified six systematic reviews incorporating four primary studies overall, including two randomized trials. We extracted data from the systematic reviews, reanalyzed data from primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach...
