The inward rectifier K(+) channel Kir2.1 contributes to the maintenance of the resting cell membrane potential in excitable cells. Loss of function mutations of KCNJ2 encoding Kir2.1 result in Andersen-Tawil syndrome, a disorder characterized by periodic paralysis, cardiac arrhythmia, and dysmorphic features. The ubiquitously expressed protein kinase B (PKB/Akt) activates ...

Chronic lymphocytic leukemia (CLL) with 17p deletion or mutations of the TP53 gene has a very poor outcome. Optimal treatment of these patients remains a major clinical challenge, and disagreement on the optimal treatment approach exists. Conventional chemo-immunotherapy with rituximab in combination with purine analogues yields lower response-rates and less ...

Deletions of the chromosomal region 2q37 cause brachydactyly-mental retardation syndrome (BDMR), also known as Albright hereditary osteodystrophy-like syndrome. Recently, histone deacetylase 4 (HDAC4) haploinsufficiency has been postulated to be the critical genetic mechanism responsible for the main clinical characteristics of the BDMR syndrome like developmental delay and behavioural abnormalities in ...

Nonstructural protein 1 (NS1) is a non-structural protein of avian influenza virus. It can interact with a variety of proteins of the host cells, enhancing the expression of viral proteins and changing the growth and metabolism of the host cells, thereby enhancing the virus' pathogenicity and virulence. To investigate whether ...

We have successfully synthesized S = 1/2 kagome antiferromagnets MCu(3)(OH)(6)Cl(2) (M = Ni and Co) by a hydrothermal method with a rotating pressure vessel. Structural characterization shows that both compounds have similar crystal structure to ZnCu(3)(OH)(6)Cl(2) with [Formula: see text] symmetry. As with ZnCu(3)(OH)(6)Cl(2), the compounds show no obvious hysteresis at 2 K. ...

Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause. IPF is associated with an increased risk of lung cancer, and lung cancer patients with IPF undergoing pulmonary resection for non-small cell lung cancer have increased postoperative morbidity and mortality. Especially, ...

BACKGROUND: Laparoscopic adjustable gastric banding (LAGB) is one of the most frequently performed bariatric surgeries. Even with a high failure rate, revisional procedures such as re-banding or laparoscopic Roux-en-Y gastric bypass (LRYGB) were commonly performed. Recently, conversions of LAGB to laparoscopic sleeve gastrectomy (LSG) were reported. We will review our ...

Microscopic polyangiitis (MPA) frequently involves the lungs. However, as opposed to granulomatosis with polyangiitis (Wegener's), limited forms are not recognised. In recent years, cases have been reported in which the lungs were affected without other organ manifestations. For years, many have been labelled as idiopathic pulmonary fibrosis (IPF). In this ...

BACKGROUND: Given the significant side-effects and healthcare costs associated with telaprevir- or boceprevir-combination therapy, identifying patients likely to respond to dual therapy peg-interferon (Peg-IFN)/ribavirin is highly desirable. Since the perception of how large the pool of patients who may achieve rapid virologic response (RVR) is vaguely ascertained, we searched the ...

Environmental factors, such as storage time, frequency of bottle reuse and temperature, have been shown to facilitate antimony (Sb) leaching from water- and food-packaging materials. The globally escalating consumption of water packaged in Sb-containing bottles, such as that of polyethylene terephthalate (PET), could increase human daily Sb doses. This study ...

ABSTRACT: BACKGROUND: Japanese gentians (Gentiana triflora and Gentiana scabra) are amongst the most popular floricultural plants in Japan. However, genomic resources for Japanese gentians have not yet been developed, mainly because of the heterozygous genome structure conserved by outcrossing, the long juvenile period, and limited knowledge about the inheritance of ...

We report a case of nocardiosis in a patient with several risk factors for this rare infection. Radiologically, the patient's multiple lung abscesses were misinterpreted as pulmonary metastases. Diagnosis was finally reached by the growth of Nocardia asteroides in two different blood culture sets. Nocardia bacteraemia is a rare clinical ...

The potential atheroprotective effects of glucagon-like peptide-1 (GLP-1), long-acting GLP-1 analogues and inhibitors of the enzyme dipeptidyl peptidase 4 (DPP-4) are currently the subject of intense research. Recent evidence suggests the effects of DPP-IV inhibitors, may, in-part, be mediated by GLP-1 independent molecular mechanisms. In this report we demonstrate that ...

Despite near universal vaccine coverage, the bacterial pathogen Bordetella pertussis has re-emerged as a major public health concern. We recently developed a baboon (Papio anubis) model of pertussis that provides an excellent model of human pertussis. Using this model, the immune response to pertussis was characterized by measuring cytokines in ...

We investigated the physiological mechanism of grapheme-color synesthesia using metacontrast masking. A metacontrast target is rendered invisible by a mask that is delayed by about 60 ms; the target and mask do not overlap in space or time. Little masking occurs, however, if the target and mask are simultaneous. This effect ...

Radionuclide cardiac imaging has potential to assess underlying molecular, electrophysiologic, and pathophysiologic processes of cardiac disease. An area of current interest is cardiac autonomic innervation imaging with a radiotracer such as (123)I-meta-iodobenzylguanidine ((123)I-mIBG), a norepinephrine analogue. Cardiac (123)I-mIBG uptake can be assessed by planar and SPECT techniques, involving determination of ...

In Western populations, male gender atypicality (i.e., cross-gender behavior and identity) and male androphilia (i.e., sexual attraction to adult males) tend to cluster in particular families. Here, we examined whether this familial clustering effect extended to non-Western populations by examining the genealogical relationships of 17 Samoan transgendered androphilic males, known ...

Franz Schneider (13.09.1812-29.11.1897) in 1850 was appointed the first lecturer on "Chemistry for physicians" by the Viennese university. Two years later he accepted the professorship in the military medical schools in the "Josephinum" from where he shifted to the philosophical faculty as professor of "Common and medical chemistry". Soon after ...

The antiapoptotic factor Livin has been considered critical for tumor progression and poor prognosis for variant types of tumors. However, there are only limited reports regarding its expression and biological functions in colon cancer. Here, we examined Livin expression in four colon cancer cell lines (HCT116, RKO, KM12C, and SW620) ...
