Using multiple assessments to evaluate medical students' clinical ability in psychiatric clerkships.

Background: No single assessment method can successfully evaluate the clinical ability of medical students in psychiatric clerkships; however, few studies have examined the efficacy of multiple assessments, especially in psychiatry. The aim of this study was to examine the relationship among different types of assessments of medical students' clinical ability in psychiatric clerkships and whether it is reasonable to use multiple assessments.

Method: A group of 196 students were enrolled during their psychiatric clerkship between September 2008 and May 2009 in Kaohsiung, Taiwan.

Long-term outcomes of distant metastasis from differentiated thyroid carcinoma.

Background:   The aim of this study was to identify the prognostic factors of long-term survival and optimal therapeutic protocol for patients with distant metastasis secondary to differentiated thyroid carcinoma (DTC).

Methods:   A retrospective review of 1665 patients with DTC treated at a regional tertiary hospital in Taiwan between 1986 and 2010 was performed. Among them, 207 patients were found to have distant metastasis.

Inhibition of Rac GTPase signaling and downstream prosurvival Bcl-2 proteins as combination targeted therapy in MLL-AF9 leukemia.

The Rac family of small Rho GTPases coordinates diverse cellular functions in hematopoietic cells including adhesion, migration, cytoskeleton rearrangements, gene transcription, proliferation, and survival. The integrity of Rac signaling has also been found to critically regulate cellular functions in the initiation and maintenance of hematopoietic malignancies. Using an in vivo gene targeting approach, we demonstrate that Rac2, but not Rac1, is critical to the initiation of acute myeloid leukemia in a retroviral expression model of MLL-AF9 leukemogenesis.

Cdc42 regulates extracellular matrix remodeling in three dimensions.

Extracellular matrix (ECM) actively participates in normal cell regulation and in the process of tumor progression. The Rho GTPase Cdc42 has been shown to regulate cell-ECM interaction in conventional two-dimensional culture conditions by using dominant mutants of Cdc42 in immortalized cell lines that may introduce nonspecific effects. Here, we employ three-dimensional culture systems for conditional gene targeted primary mouse embryonic fibroblasts that better simulate the reciprocal and adaptive interactions between cells and surrounding matrix to define the role of Cdc42 signaling pathways in ECM organization.

Relationships among Constitution, Stress, and Discomfort in the First Trimester.

The purpose of this study was to explore correlations among constitution, stress, and discomfort symptoms during the first trimester of pregnancy. We adopted a descriptive and correlational research design and collected data from 261 pregnant women during their first trimester in southern Taiwan using structured questionnaires. Results showed that (1) stress was significantly and positively correlated with Yang-Xu, Yin-Xu, and Tan-Shi-Yu-Zhi constitutions, respectively; (2) Yin-Xu and Tan-Shi-Yu-Zhi constitutions had significant correlations with all symptoms of discomfort, while Yang-Xu had significant correlations with all symptoms of discomfort except for "running nose"; (3) Tan-Shi-Yu-Zhi constitution and stress were two indicators for "fatigue"; Tan-Shi-Yu-Zhi was the indicator for "nausea"; Yang-Xu and Yin-Xu were indicators for "frequent urination.

Matriptase is inhibited by extravascular antithrombin in epithelial cells but not in most carcinoma cells.

Antithrombin, a major anticoagulant, is robustly transported into extravascular compartments where its target proteases are largely unknown. This serpin was previously detected in human milk as complexes with matriptase, a membrane-bound serine protease broadly expressed in epithelial and carcinoma cells, and under tight regulation by hepatocyte growth factor activator inhibitor (HAI)-1, a transmembrane Kunitz-type serine protease inhibitor that forms heat-sensitive complexes with active matriptase. In the current study, we detect, in addition to matriptase-HAI-1 complexes, heat-resistant matriptase complexes generated by nontransformed mammary, prostate, and epidermal epithelial cells that we show to be matriptase-antithrombin complexes.

Steric zipper formed by hydrophobic peptide fragment of Syrian hamster prion protein.

Steric zippers, where the residues of two neighboring β-sheet layers are tightly interdigitated, have been proposed as fundamental structural units of amyloid fibrils by Eisenberg and co-workers. The steric zipper formed by polypeptides containing the palindromic sequence AGAAAAGA has a distinctive feature that the distance between two interdigitated β-sheet layers is comparable to the interstrand distance of the individual β-sheet. This structural motif is of great interest in the study of prion disease because the AGAAAAGA sequence is highly conserved in prion proteins of different species.

Spontaneous dissection of the vertebral artery: report of three cases.

Purpose: Vertebral artery dissection (VAD), although uncommon, is an important cause of ischemic stroke in young adults. Without prompt diagnosis and treatment, it may cause mortality and morbidity. Spontaneous VAD related to abrupt neck position change, sudden sneezing, or severe cough and vomiting after fish bone choking are rarely reported.

Noninvasive positive pressure ventilation in the management of post-thyroidectomy tracheomalacia.

Background: Post-thyroidectomy tracheomalacia is a rare but complicated problem. It has often been treated with tracheostomy or prolonged endotracheal intubation. However, noninvasive positive pressure ventilation (NPPV) has been successfully employed with increasing frequency in patients with respiratory failure from other causes.

Targeting pre-ligand assembly domain of TNFR1 ameliorates autoimmune diseases - an unrevealed role in downregulation of Th17 cells.

The pre-ligand assembly domain (PLAD) of tumor necrosis factor receptors mediates specific ligand-independent receptor assembly and subsequent signaling. However, the physiological role of PLAD in the regulation of TNFR-mediated immune responses in autoimmunity is still unclear. By using the recombinant PLAD.

Rapid isolation and characterization of bacterial lipopeptides using liquid chromatography and mass spectrometry analysis.

The structural analysis of post-translational modifications (PTMs) of lipoproteins is difficult due to the hydrophobic properties of their fatty acid moieties. At the present time, the relative positions of fatty acid components on the N-acyl-S-diacylglycerylcysteine core structure has not been specifically identified in any natural or bacterial expressed recombinant lipoproteins. In this study, we describe a rapid solid-phase extraction using acetonitrile and isopropanol method that can be performed manually to isolate large amounts of relatively pure lipopeptides generated by the limited tryptic-digestion of recombinant lipoproteins.

BNCT with BPA (400 mg/kg) injected in 2 phases and prescription dose of 12-35 Gy (Eq.)/fraction for 2 fractions at 30 day interval can be given with sustained blood boron concentration and tolerable early toxicities for recurrent H & N cancer.

Singlet-triplet excitations in the unconventional spin-Peierls TiOBr compound.

We have performed time-of-flight neutron scattering measurements on powder samples of the unconventional spin-Peierls compound TiOBr using the fine-resolution Fermi chopper spectrometer (SEQUOIA) at the Spallation Neutron Source at Oak Ridge National Laboratory. These measurements reveal two branches of magnetic excitations within the commensurate and incommensurate spin-Peierls phases, which we associate with n=1 and n=2 triplet excitations out of the singlet ground state. These results represent the first direct measurement of the singlet-triplet energy gap in TiOBr, which has a value of E(g)=21.

Methods: Our population for this study was identified before the end of 1999. The study included 59,257 patients with schizophrenia and 178,156 age- and gender-matched individuals without schizophrenia as controls, who were selected from the 23,981,020 subjects in the National Health Insurance Research Database (NHIRD), which consists of 96% of the entire Taiwanese population.

[Family caregiver issues: gender, privacy, and public policy perspectives].

Due to the phenomenon of Taiwan'saging population has made, long-term care has become an issue of increasingly emphasized importance. According to the statistics, the family takes responsibility for most long-term care duties and more than 70% of primary family caregivers are female. In the past, because of gender-based divisions of labor and gender role expectations made, it was taken for granted that females would be the socially preferred family caregivers.

Sensitizing effect of 3-methyladenine on radiation-induced cytotoxicity in radio-resistant HepG2 cells in vitro and in tumor xenografts.

Many recent efforts have focused on targeting cell death pathways for discovering new cancer therapies. The relative resistance of liver cancer cells to ionizing radiation (IR) and chemotherapeutic agents due to autophagic response limits the available treatment options for this type of cancer. In this study, 3-methyladenine (3-MA), an autophagy inhibitor, was investigated for its potential to enhance radio-sensitivity under radio-resistant conditions both in vitro and in vivo.

Potential of using boric acid as a boron drug for boron neutron capture therapy for osteosarcoma.

Osteosarcoma is a malignant tumor commonly found in human and animals. The ability of boric acid (BA) to accumulate in osteosarcoma due to the mechanism of the bone formation of cancer cells would make boron neutron capture therapy (BNCT) an alternative therapy for osteosarcoma. This study evaluated the feasibility of using BA as the boron drug for BNCT of bone cancer.
