Quantification of 23 Volatile Organic Compounds with a Single Reference Material Using Post-column Reaction Gas Chromatography Combined with a Stainless-steel Heating Furnace.

We built a heating furnace using stainless-steel instead of aluminum in gas chromatography combined with an oxidation/reduction system; it increased the oxidation temperature to 650°C. At 600°C, it completely oxidized five organochlorine compounds. This system was applied to a standard solution of 23 volatile organic compounds.

Fbxo22-mediated KDM4B degradation determines selective estrogen receptor modulator activity in breast cancer.

The agonistic/antagonistic biocharacter of selective estrogen receptor modulators (SERMs) can have therapeutic advantages, particularly in the case of premenopausal breast cancers. Although the contradictory effects of these modulators have been studied in terms of crosstalk between the estrogen receptor α (ER) and coactivator dynamics and growth factor signaling, the molecular basis of these mechanisms is still obscure. We identify a series of regulatory mechanisms controlling cofactor dynamics on ER and SERM function, whose activities require F-box protein 22 (Fbxo22).

Lower airway obstruction due to a massive clot resulting from late bleeding following mini-tracheostomy tube insertion and subsequent clot removal and re-intubation.

Background: Easier to perform than the conventional procedure, mini-tracheostomy (MT) is widely used in the operating room or intensive care unit to remove sputum or other obstructions of the upper airway. This option, however, does carry the risk of various complications, including malposition, disposition, bleeding, and subcutaneous emphysema. Here, we report a case of endotracheal tube obstruction due to a massive clot resulting from late bleeding around the insertion site of an MT tube.

Disappearing everyday materials: The displacement of medical resources following disaster in Fukushima, Japan.

This study draws upon interviews of medical staff working in the city of Minamisoma, Japan, following the 2011 Triple Disaster. It investigates staff responses to the disruption of material resources as a consequence of the disaster and its management. The disruption of spaces, and the loss of oxygen supplies, food, and medications impacted upon staff experience and the ability of institutions to care for patients.

Impact of a Multidisciplinary Round Visit for the Management of Dysphagia Utilizing a Wi-Fi-Based Wireless Flexible Endoscopic Evaluation of Swallowing.

Objectives: The management of dysphagia requires a multidisciplinary approach, especially in large-scale hospitals. We introduce a novel protocol using a Wi-Fi-based flexible endoscopic evaluation of swallowing (FEES) system and aim to verify its effectiveness in evaluation and rehabilitation of inpatients with dysphagia.

Method: We conducted novel Wi-Fi-based FEES at the bedside using 3 iPads as monitors and recorders.

[Pulmonary Artery Catheter Injured by Ablation Device during Maze Procedure].

We report a case of pulmonary artery catheter (PAC) injury by radio frequency device for maze procedure. A 64-year-old female with severe mitral insufficiency, tricuspid insufficiency and paroxysmal atrial fibrillation was scheduled for mitral valve repair, tricuspid annulo- plasty and maze procedure including right-sided maze. Under general anesthesia, a PAC was inserted to pul- monary artery (PA) uneventfully.

Assessment and refinement of eukaryotic gene structure prediction with gene-structure-aware multiple protein sequence alignment.

Background: Accurate computational identification of eukaryotic gene organization is a long-standing problem. Despite the fundamental importance of precise annotation of genes encoded in newly sequenced genomes, the accuracy of predicted gene structures has not been critically evaluated, mostly due to the scarcity of proper assessment methods.

Results: We present a gene-structure-aware multiple sequence alignment method for gene prediction using amino acid sequences translated from homologous genes from many genomes.

Xnr3 affects brain patterning via cell migration in the neural-epidermal tissue boundary during early Xenopus embryogenesis.

Neural induction and anteroposterior neural patterning occur simultaneously during Xenopus gastrulation by the inhibition of BMP and Wnt signaling, respectively. However, other processes might be necessary for determining the neural-epidermal boundary. Xenopus nodal-related-3 (Xnr3) is expressed in dorsal blastula and plays a role in neural formation.

Combinatorial motif analysis of regulatory gene expression in Mafb deficient macrophages.

Background: Deficiency of the transcription factor MafB, which is normally expressed in macrophages, can underlie cellular dysfunction associated with a range of autoimmune diseases and arteriosclerosis. MafB has important roles in cell differentiation and regulation of target gene expression; however, the mechanisms of this regulation and the identities of other transcription factors with which MafB interacts remain uncertain. Bioinformatics methods provide a valuable approach for elucidating the nature of these interactions with transcriptional regulatory elements from a large number of DNA sequences.
