Academic publications have so far hardly paid any attention to the topic of biased medical experts or expert opinions. This is the first attempt to systematically describe and analyze the issue, drawing on the author's many years of giving expert opinions as a neuropsychiatrist on matters relating to social legislation and civil law. In addition to dealing with questions of definition, this article outlines the features of biased expert opinions, particularly focusing on the role of insurance and private experts...

Delivery of neurotrophins and neuropeptides via long-range trafficking of dense core vesicles (DCVs) from the cell soma to nerve terminals is essential for synapse modulation and circuit function. But the mechanism by which transiting DCVs are captured at specific sites is unknown. Here, we discovered that Synaptotagmin-4 (Syt4) regulates the capture and spatial distribution of DCVs in hippocampal neurons. We found that DCVs are highly mobile and undergo long-range translocation but switch directions only at the distal ends of axons, revealing a circular trafficking pattern...

Bacterial infection often leads to suppression of mRNA translation, but hosts are nonetheless able to express immune response genes through as yet unknown mechanisms. Here, we use a Drosophila model to demonstrate that antimicrobial peptide (AMP) production during infection is paradoxically stimulated by the inhibitor of cap-dependent translation, 4E-BP (eIF4E-binding protein; encoded by the Thor gene). We found that 4E-BP is induced upon infection with pathogenic bacteria by the stress-response transcription factor ATF4 and its upstream kinase, GCN2...

ETHNOPHARMACOLOGICAL RELEVANCE: Aconitum carmichaelii (AC) is a common herbal medicine used as anti-inflammatory and analgesic agent in Eastern Asia. In Korea, a commercial processed AC (Aconibal(®)) is traditionally used to treat the symptoms of spondylosis deformans and rheumatic pain. AIM OF STUDY: Rheumatoid arthritis (RA) is systemic and auto-immune disease characterized by chronic inflammation. Methotrexate (MTX) is often the first-line therapy for RA. If MTX monotherapy is ineffective or RA is initially severe, adding a tumor necrosis factor (TNF)-α inhibitor to the treatment can be beneficial...

AIMS: Several experimental studies have demonstrated that removal of the spleen accelerates liver regeneration after partial hepatectomy. While the mechanism of splenectomy promotes liver regeneration by the improvement of the formation of tight junction and the establishment of hepatocyte polarity is still unknown. MAIN METHODS: We analyzed the cytokines, genes and proteins expression between 70% partial hepatectomy mice (PHx) and simultaneous 70% partial hepatectomy and splenectomy mice (PHs) at predetermined timed points...

Ascher's syndrome consists of double lip, blepharochalasis and sometimes non-toxic thyroid enlargement. It is a rare, benign, rarely reported, and sometimes misdiagnosed condition that most often affects patients under 20 years old. The etiology remains unknown, although factors such as trauma, hormonal dysfunction and heredity have been suggested. Treatment based on surgical intervention is indicated to improve aesthetics or function. The presented case shows a patient diagnosed with Ascher's syndrome based on clinical findings such as double lip and blepharochalasis...

An integrated molecular surveillance for tuberculosis (TB) improves the understanding of ongoing TB transmission by combining molecular typing and epidemiological data. However, the implementation of an integrated molecular surveillance for TB is complex and requires thoughtful consideration of feasibility, demand, public health benefits and legal issues. We aimed to pilot the integration of molecular typing results between 2008 and 2010 in the German Federal State of Baden-Württemberg (population 10.88 Million) as preparation for a nationwide implementation...

Under gradual change of a driver, complex systems may switch between contrasting stable states. For many ecosystems it is unknown how rapidly such a critical transition unfolds. Here we explore the rate of change during the degradation of a semiarid ecosystem with a model coupling the vegetation and geomorphological system. Two stable states-vegetated and bare-are identified, and it is shown that the change between these states is a critical transition. Surprisingly, the critical transition between the vegetated and bare state can unfold either rapidly over a few years or gradually over decennia up to millennia, depending on parameter values...

BACKGROUND: The prevalence of hepatitis C (HCV) and HIV among persons who inject drugs (PWID) and the ability of these diseases to spread through injection networks are well documented in urban areas. However, less is known about injection behaviors in rural areas. OBJECTIVES: This study focuses on the association between the number of self-reported injection partners with the PWID's self-reported HCV and HIV status. Injection networks provide paths for infection and information to flow, and are important to consider when developing prevention and intervention strategies...

Quantitative detection of pathogenic viruses in the environmental water is essential for the assessment of water safety. It is known that some of natural organic substances interfere with virus detection processes, i.e., nucleic acid extraction and reverse transcription-PCR. Such substances are carried over into a sample after virus concentration. In this study, inhibitory substances in coastal water samples were characterized in view of their effects on efficiency of virus detection and property as organic matters...

Recently developed tissue-hydrogel methods for specimen expansion now enable researchers to perform super-resolution microscopy with ~65 nm lateral resolution using ordinary microscopes, standard fluores-cent probes, and inexpensive reagents. Here we use the combination of specimen expansion and the optical super-resolution microscopy technique structured illumination microscopy (SIM) to extend the spatial reso-lution to ~30 nm. We apply this hybrid method, which we call ExSIM, to study the cytoskeleton of the im-portant human pathogen Giardia lamblia including the adhesive disc and flagellar axonemes...

Photothermal induced resonance (PTIR), also known as AFM-IR, is a scanning probe technique that provides sample composition information with a lateral resolution down to 20 nm. Interest in PTIR stems from its ability to identify unknown samples at the nanoscale thanks, in first approximation, to the direct comparability of PTIR spectra with far-field infrared databases. The development of rapidly tuning quantum cascade lasers has increased the PTIR throughput considerably, making nanoscale hyper-spectral imaging within a reasonable timeframe possible...
