Objective: The diagnosis of cancer in pregnancy is rare, but might become more relevant even for head and neck cancer patients due to a shift of age of primipara towards the last third of reproductive years. Unsureness exists about the risk and benefit of diagnostic and therapeutic cancer modalities for the unborn and established recommendations are still missing. But, according to recent data, even multimodal therapeutic approaches (e. g. surgery, radiation, chemotherapy) seem possible in face of pregnancy and should be traded against the risk of prematurity...

Professor Emil Redlich (1866-1930) of the University of Vienna was born 150 years ago. Raised in a humble environment, he became an eminent researcher and neurology scholar, and succeeded in laying some of the key foundations of neuroanatomy and neuropathology. His name is linked to medical eponyms that define the dorsal root entry zone into the spinal cord, epidemic disseminated encephalomyelitis, narcolepsy, senile plaques and dementia. As its first director, he managed to organize the Maria-Theresien-Schlössel into a first-class neuropsychiatric hospital...

We aimed to identify an optimum nano-carrier system to deliver tumor antigen to dendritic cells (DCs) for efficient targeting of tumor reinitiating cells (TRICs) in gynecological malignancies. Different lipid based nano-carrier systems i.e. liposomes, ethosomes and solid lipid nanoparticles (SLNPs) were examined for their ability to activate DCs in allogeneic settings. Out of these three, the most optimized formulation was subjected for cationic and mannosylated surface modification and pulsed with DCs for specific targeting of tumor cells...

The efficient coding hypothesis assumes that biological sensory systems use neural codes that are optimized to best possibly represent the stimuli that occur in their environment. Most common models use information-theoretic measures, whereas alternative formulations propose incorporating downstream decoding performance. Here we provide a systematic evaluation of different optimality criteria using a parametric formulation of the efficient coding problem based on the Lp reconstruction error of the maximum likelihood decoder...

Enzyme replacement therapy with intravenous idursulfase (recombinant iduronate-2-sulfatase) is approved for the treatment of Hunter syndrome. Intravenous administration does not, however, treat the neurological manifestations, due to its low central nervous system bioavailability. Using intrathecal-lumbar administration, iduronate-2-sulfatase is delivered directly to the central nervous system. This study investigates the central nervous system biodistribution of intrathecal-lumbar administered iduronate-2-sulfatase in cynomolgus monkeys...

Dengue virus (DENV) is the causative agent of dengue fever and dengue hemorrhagic fever. The virus is endemic in over 120 countries, causing over 350 million infections per year. Dengue vaccine development is challenging because of the need to induce simultaneous protection against four antigenically distinct DENV serotypes and evidence that, under some conditions, vaccination can enhance disease due to specific immunity to the virus. While several live-attenuated tetravalent dengue virus vaccines display partial efficacy, it has been challenging to induce balanced protective immunity to all 4 serotypes...

Expanding access to office-based medication-assisted treatment with buprenorphine/naloxone for opioid dependence is a key part of the national strategy to address the opioid abuse epidemic (1). However, as buprenorphine/naloxone prescribing increased, emergency department (ED) visits and hospitalizations for unsupervised ingestions by young children began to increase, with buprenorphine/naloxone ingestions becoming the most common cause of hospitalization for medication ingestions by young children during 2010-2011 (2)...

Marijuana-based treatment for refractory epilepsy shows promise in surveys, case series and clinical trials. However, literature on their electroencephalography (EEG) effects is sparse. Our objective is to analyze the effect of marijuana on EEG in a 24-year-old patient with idiopathic generalized epilepsy (IGE) treated with cannabis. We blindly reviewed three long-term EEGs-a 24-hour study while only on antiepileptic drugs (AEDs), a 72-hour EEG with Cannabis indica smoked on days one and three in addition to AEDs and a 48-hour EEG with combination C...

When investigating a new catalytic reaction, scientists may wonder if the crude reaction product can be easily separated and purified. We present here a new concept-distillation resistance-to assess the potential of distillation as a purification technique and to guide catalyst formulation or operation at the very early stage of the research. Distillation resistance, which has been developed from the analysis of 15 industrial distillation trains, can be quickly calculated with knowledge of only the product composition and atmospheric boiling points of the components...

The aim of this study was to prepare a solid dispersion formulation of curcumin to enhance its solubility, dissolution rate, and oral bioavailability. The formulation was prepared with d-α-tocopheryl polyethylene glycol 1000 succinate (TPGS) and mannitol using solvent evaporation and freeze-drying methods, which yielded a solid dispersion composed of curcumin, TPGS, and mannitol at a ratio of 1:10:15 (w/w/w). The solubility and dissolution rate of the curcumin solid dispersion markedly improved compared with those of curcumin powder and a physical mixture of curcumin, TPGS, and mannitol...

The work of Herbert Spencer was a crucial influence on the development of Peter Kropotkin's historical sociology. However, scholars have underestimated this relationship; either overlooking it entirely, or minimizing Kropotkin's attachment to Spencer with the aim of maintaining the utility of his political thought in the present. This article contests these interpretations by analyzing Kropotkin's reading of Spencer's epistemological, biological, and political ideas. It argues that Kropotkin was engaged in a critical dialogue with Spencer, incorporating many Spencerian principles in his own system, but also using this reading to articulate a distinctive anarchist politics...
