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...

Anton V Chizhov
The conductance-based refractory density (CBRD) approach is an efficient tool for modeling interacting neuronal populations. The model describes the firing activity of a statistical ensemble of uncoupled Hodgkin-Huxley-like neurons, each receiving individual Gaussian noise and a common time-varying deterministic input. However, the approach requires experimental validation and extension to cases of distributed input signals (or input weights) among different neurons of such an ensemble. Here the CBRD model is verified by comparing with experimental data and then generalized for a lognormal (LN) distribution of the input weights...

In order to realize a combination of chemotherapy and selective drug release into tumor cells, novel pH-sensitive prodrugnanoparticles were designed and prepared via the self-assembly of a synthetic amphiphilic macromolecular prodrug for the selective co-delivery of doxorubicin (Dox) and curcumin (Cur). Dox was covalently conjugated to the oxidized sodium alginate through a Schiff base reaction to produce an amphiphilic macromolecular prodrug, and the prodrug was subsequently self-assembled into nanoparticles (Dox-NPs) in an aqueous solution, which were responsive to the acidic environment in tumor cells...

BACKGROUND AND AIMS: The brain reward system is key to understanding adolescent obesity in the current obesogenic environment, rich in highly appetising stimuli, to which adolescents are particularly sensitive. We aimed to examine the association between body fat levels and brain reward system responsivity to general (monetary) rewards in male and female adolescents. METHOD: Sixty-eight adolescents (34 females; mean age [standard deviation]=16.56 [1.35]) were measured for body fat levels with bioelectric impedance, and underwent a functional magnetic resonance imaging (fMRI) scan during the Monetary Incentive Delay (MID) task...

The inflammatory response can produce damage to host tissues and in several infectious diseases the most severe symptoms are due to immunopathology rather than a direct effect of pathogen multiplication. One hypothesis for the persistence of inflammatory damage posits that the benefits of protection towards infection outweigh the costs. We used data on knocked-out (KO) cytokine models [and the corresponding wild-type (WT) controls] to test this hypothesis. We computed differences in pathogen load and host survival between WT and KO and divided them by the WT values...

In dose ranging clinical trials, it is critical to investigate the dose-response profile and to identify a minimum effective dose (MED) to guide the dose selection for phase 3 confirmatory trials. Traditional dose ranging trials focus on pairwise comparisons between placebo and each investigational dose, while in recent years MCP-Mod (Multiple Comparison Procedures & Modeling) arose and gained popularity in the design and analysis of dose ranging trials. Comprehensive comparison between MCP-Mod and other methods have been made on continuous variables assuming a normal distribution...

Partition coefficients between human stratum corneum lipids and water (K(sclip/w)) are collected or deduced from a variety of sources in a manner that approximately doubles the available data compared to the current state-of-the-art model [Hansen et al., Adv Drug Deliv Rev 65:252-264 (2013)]. An additional datum for water itself in porcine SC that considerably extends the molecular size and lipophilicity range of the dataset is considered. The data are analyzed in terms of an extended linear free energy relationship involving octanol/water partition coefficients, Abraham solvation parameters and a secondary, power law molecular weight dependence...

Human milk contains essential micronutrients for growth and development during early life. Environmental pollutants, such as potentially toxic metals, can also be transferred to the infant through human milk. These elements have been well-studied, but changing diets and environments and advances in laboratory technology require re-examining these elements in a variety of settings. The aim of this study was to characterize the concentrations of essential and toxic metals in human milk from four diverse populations...

Medical schools in the United States continue to undergo curricular change, reorganization, and reformation as more schools transition to an integrated curriculum. Anatomy educators must find novel approaches to teach in a way that will bridge multiple disciplines. The cadaveric extraction of the central nervous system (CNS) provides an opportunity to bridge gross anatomy, neuroanatomy, and clinical neurology. In this dissection, the brain, brainstem, spinal cord, cauda equina, optic nerve/tract, and eyes are removed in one piece so that the entire CNS and its gateway to the periphery through the spinal roots can be appreciated...

Erythropoietin (EPO) has been well known as a hematopoietic cytokine over the past decades. However, recent reports have demonstrated that EPO plays a neuroprotective role in the central nervous system, and EPO has been considered as a therapeutic target in neurodegenerative diseases such as ischemic stroke. Despite the neuroprotective effect of EPO, clinical trials have shown its unexpected side effects, including undesirable proliferative effects such as erythropoiesis and tumor growth. Therefore, the development of EPO analogs that would confer neuroprotection without adverse effects has been attempted...
