Acute Exacerbation of Rheumatoid Arthritis-Associated Interstitial Lung Disease After Thoracic Surgery in the Absence of Usual Interstitial Pneumonia Pattern on CT.

The usual interstitial pneumonia (UIP) pattern observed on chest computed tomography (CT) is considered a risk factor for the development of postoperative acute exacerbation in interstitial lung disease (ILD). However, the risk factors for acute exacerbation in patients with rheumatoid arthritis (RA)-associated ILD have not been adequately investigated. We present a case of postoperative acute exacerbation after thoracic surgery in a 73-year-old man with RA-ILD and non-UIP pattern on chest CT.

Incidence of perioperative hypotension in patients undergoing transurethral resection of bladder tumor after oral 5-aminolevulinic acid administration: a retrospective multicenter cohort study.

Purpose: Tumors can be visualized using 5-Aminolevulinic acid hydrochloride (5-ALA) during transurethral resection of bladder tumors (TURBT). Hypotension is an adverse effect of 5-ALA; however, its incidence and morbidity rates are unknown. This study aimed to describe the incidence of perioperative hypotension and identify risk factors for hypotension among patients after 5-ALA administration in TURBT.

Mechanical Positive Pressure Ventilation and Voice Training via the Blom® Tracheostomy Tube: A Case Study.

Patients with a Blom® tracheostomy tube (containing a cuff) can vocalize while on mechanical ventilation, which can significantly improve the patient's quality of life. This is brought by the purpose-built structure of the tracheostomy tube that allows the expiration to be expelled through the glottis. However, this characteristic may complicate the measurement of the patient's tidal volume, as most of the expiration does not return to the ventilator.

-Methylamide-structured SB366791 derivatives with high TRPV1 antagonistic activity: toward PET radiotracers to visualize TRPV1.

Transient receptor potential cation channel subfamily V member 1 (TRPV1)-targeted compounds were synthesized by modifying the structure of SB366791, a pharmaceutically representative TRPV1 antagonist. To avoid amide-iminol tautomerization, structurally supported -methylated amides (, 3-alkoxy-substitued -meythylamide derivatives of SB366791) were evaluated using a Ca influx assay, in which cells expressed recombinant TRPV1 in the presence of 1.0 μM capsaicin.

Monitored Anesthesia Care of Two Patients with Highly Elevated Subpulmonic Ventricular Pressure due to Adult Congenital Heart Disease.

Procedural sedation and analgesia for patients with adult congenital heart disease (ACHD) and highly elevated subpulmonic ventricular pressure require proper anesthesia care to prevent a pulmonary hypertensive crisis. We describe the monitored anesthesia care (MAC) of two patients with ACHD (a complete atrioventricular septal defect and congenitally corrected transposition of the great arteries) and highly elevated subpulmonic ventricular pressure. In both patients, preprocedural transthoracic echocardiography was useful for detecting severely elevated subpulmonic ventricular pressure.

Severe and Prolonged Hypotension After Oral 5-Aminolevulinic Acid Administration in a Patient With End-Stage Renal Disease Undergoing Transurethral Resection of a Bladder Tumor: A Case Report.

A 72-year-old man with end-stage renal disease (ESRD) undergoing transurethral resection of a bladder tumor experienced severe and prolonged hypotension after receiving oral 5-aminolevulinic acid (5-ALA). Continuous infusions of norepinephrine and vasopressin ultimately resolved the hypotension over the course of 26 hours. It is uncertain whether 5-ALA is causative or is a contributing factor that influences other factors, such as hypovolemia after hemodialysis and autonomic nerve dysfunction associated with ESRD.

Solubility-Improved 10-O-Substituted SN-38 Derivatives with Antitumor Activity.

With the objective of improving the poor water solubility of the potent antitumor compound SN-38, 10-O-substituted SN-38 derivatives were developed by the introduction of fluoroalkyl, fluorobenzoyl, or bromobenzoyl groups. The 10-O-fluoropropyl-substituted compound 2 {(S)-4,11-diethyl-9-(3-fluoropropoxy)-4-hydroxy-1H-pyrano[3',4':6,7]indolizino[1,2-b]quinoline-3,14(4H,12H)-dione} was found to be 17-fold more soluble than SN-38 in phosphate-buffered saline, and it exhibited a level of biological activity ≈50 % that of SN-38 in a cytotoxicity assay using the prostate cancer cell line PC-3. Five other derivatives did not show solubility improvements to the same extent, but their activities in cytotoxicity assays were nearly the same as that of SN-38.

[Benefit of Intraoperative Mannitol Use during Endoscopic Surgery for Intracerebral Hemorrhage].

Background: Endoscopic hematoma evacuation is an established treatment option for patients with intra- cerebral hemorrhage (ICH). The purpose of this study is to investigate the benefit of mannitol use during en- doscopic hematoma evacuation.

Methods: One hundred patients with ICH treated by endoscopic surgery from June 2009 to November 2014 were retrospectively reviewed.

Novel plant immune-priming compounds identified via high-throughput chemical screening target salicylic acid glucosyltransferases in Arabidopsis.

Plant activators are compounds, such as analogs of the defense hormone salicylic acid (SA), that protect plants from pathogens by activating the plant immune system. Although some plant activators have been widely used in agriculture, the molecular mechanisms of immune induction are largely unknown. Using a newly established high-throughput screening procedure that screens for compounds that specifically potentiate pathogen-activated cell death in Arabidopsis thaliana cultured suspension cells, we identified five compounds that prime the immune response.

Quadruple click: a facile pathway leading to tetrakis(4-(1,2,3-triazolyl)methyl)-ethylenediamine derivatives as a new class of extracting agents for soft metal ions.

Tetrakis(triazolylmethyl)ethylenediamine, which is a class of tetrakis(2-pyridylmethyl)ethylenediamine (TPEN) analogue, is synthesized by a quadruple click reaction of tetrapropargylated ethylenediamine and four equivalents of alkyl azide. The obtained compound efficiently extracted the soft metal cadmium(II) ions by solvent extraction. It is also found that an N-isopropylacryl amide (NIPA) gel using the triazole ethylenediamine as a cross-linker exhibits a temperature-dependent extraction performance.

Facile Sc(OTf)3-catalyzed generation and successive aromatization of isobenzofuran from o-dicarbonylbenzenes.

Isobenzofuran can be prepared from o-phthalaldehyde using hydrosilane. The formed isobenzofuran is trapped by an alkene via a Diels-Alder reaction. Further dehydration proceeds to furnish the conjugated aromatic compound.
