In patients with ST-segment elevation myocardial infarction (STEMI), it is unclear if combined assessment of left ventricular end-diastolic pressure (LVEDP) and left ventricular ejection fraction (LVEF) improves prediction of major adverse cardiac events (MACE). We analyzed data from 266 STEMI patients who underwent successful percutaneous coronary intervention and subsequent left ventriculography (LVG). Patients were divided into 4 groups, as follows: Group 1, LVEDP < 21 mmHg and LVEF ≥ 55%; Group 2, LVEDP < 21 mmHg and LVEF < 55%; Group 3, LVEDP ≥ 21 mmHg and LVEF ≥ 55%; and Group 4, LVEDP ≥ 21 mmHg and LVEF < 55%...

With a growing variety of nanoparticles available, research probing the influence of particle deformability, morphology, and topology on the behavior of all polymer nanocomposites is also increasing. In particular, the behavior of soft polymeric nanoparticles in polymer nanocomposites has displayed unique behavior, but their precise performance depends intimately on the internal structure and morphology of the nanoparticle. With the goal of providing guidelines to control the structure and morphology of soft polymeric nanoparticles, we have examined monomer starved semi-batch nano-emulsion polymerizations that form organic, soft nanoparticles, to correlate the precise structure of the nanoparticle to the rate of monomer addition and crosslinking density...

Extracolonic involvement of the gastrointestinal tract is extremely uncommon in ulcerative colitis (UC) and rarely found in the upper gastrointestinal tract or in postoperative cases since it typically responds to steroids. Here we report a case of UC complicated by extensive ileal inflammation that was refractory to steroids. A 20-year-old man was diagnosed with UC of typical pancolitis without ileal involvement and started treatment with pH-dependent mesalazine and oral prednisolone. Although his symptoms transiently resolved, the condition flared when the steroid dose was tapered down...

OBJECTIVE: Combined therapy with bevacizumab and paclitaxel (BP regimen) as a first-line treatment has proven highly effective with good tolerance for patients with metastatic breast cancer (MBC). The objective of this study was to examine the efficacy and safety of the BP regimen for Japanese patients with MBC in real-world clinical settings. METHODS: From June 2012 through May 2014, we recruited 94 patients at 10 medical institutions. The primary endpoint was time to treatment failure (TTF), and the secondary endpoints were overall survival (OS) and safety...

To obtain background data of NOD/Shi-scid IL-2Rγ(null) (NOG) mice, severely immunedeficient mice, a total of 120 animals were examined at 7, 26 and 52 weeks-old (20 mice/sex/group). The survival rate at 52 weeks-old was 95% (19/20) in both sexes. Clinically, circling behavior in one direction along the cage wall was observed in males after 8 weeks and females after 47 weeks-old, and hunchback position was found in males after 32 weeks-old. Hematologically, lymphocyte count markedly decreased at all ages, while white blood cell count increased in several mice at 52 weeks-old...

A reliable diagnostic device for free-electron lasers (FELs) is essential for both users and the evaluation of FEL sources and beamline optics. Here, we propose a compact bolometric radiometer (CBR) that can operate at room temperature. The CBR is mainly designed for FELs in the wavelength range from the extreme-ultraviolet (EUV) to x-rays; moreover, we confirmed that the proposed device can also be applied to synchrotron radiation. As an application of the CBR, we evaluated an FEL beamline transmission by means of bolometric technique in the EUV range for the first time, to the best of our knowledge...

Pilocytic astrocytomas and low-grade gliomas are more common compared with glioblastomas in patients with neurofibromatosis 1 (NF1). A recent genome-wide analysis has shown frequent NF1 gene alterations in the mesenchymal subtype of a glioblastoma; however, little is known about clinicopathological features of glioblastomas in NF1 patients (NF1 glioblastomas). We analyzed four NF1 glioblastomas. Radiographical and intraoperative findings showed well-circumscribed tumors from surrounding brain. Pathological analysis presented a paucity of processes with an eosinophilic cytoplasm, bizarre nuclei, xanthomatous-like appearance, multinucleated giant cells, and histiocytoid appearance...

It has been reported that chemo-radiotherapy can induce immunogenic tumor cell death (ICD), which triggers T-cell immunity mainly mediated by high-mobility group box 1 protein (HMGB1) and calreticulin. However, there is still limited information to support this theory relating to chemotherapy alone. In the present study, the expression of HMGB1 and calreticulin was evaluated by immunohistochemistry in pre-treatment biopsy specimens and surgically resected specimens, which were obtained from patients with breast cancer (n=52) and esophageal squamous cell carcinoma (ESCC) (n=8) who had been treated with neoadjuvant chemotherapy (NAC)...

Objective: The superior cluneal nerve (SCN) may become entrapped where it pierces the thoracolumbar fascia over the iliac crest; this can cause low back pain (LBP) and referred pain radiating into the posterior thigh, calf, and occasionally the foot, producing the condition known as "pseudo-sciatica." Because the SCN was thought to be a cutaneous branch of the lumbar dorsal rami, originating from the dorsal roots of L1-L3, previous anatomical studies failed to explain why SCN causes "pseudo-sciatica"...

BACKGROUND: Antenatal steroids (ANS) are standard of care for women at risk of preterm delivery; however ANS dosing and formulation have not been adequately evaluated. The standard clinical 2-dose treatment with betamethasone-acetate+betamethasone-phosphate (Beta-P+Beta-Ac) is more effective than 2 doses of Beta-P for inducing lung maturation in preterm fetal sheep. We hypothesized that the slowly-released Beta-Ac component induces similar lung maturation to Beta-P+Beta-Ac with decreased dose and fetal exposure...

We report the mechanical strength of native chitin nanofibrils. Highly crystalline α-chitin nanofibrils were purified from filaments produced by a microalgae Phaeocystis globosa, and two types of β-chitin nanofibrils were purified from pens of a squid Loligo bleekeri and tubes of a tubeworm Lamellibrachia satsuma, with relatively low and high crystallinity, respectively. These chitin nanofibrils were fully dispersed in water. Strength of individualized nanofibrils was estimated using cavitation-induced tensile fracture of nanoscale filaments in a liquid medium...

Never-dried and dried crab shell chitin and squid pen chitin samples were acid-hydrolyzed in 1M HCl at 85 °C for up to 2 h. The crystallinities, crystal sizes, and degrees of N-acetylation of the acid-hydrolyzed chitin samples are almost unchanged the same before and after acid hydrolysis. The original and acid-hydrolyzed chitin samples were dissolved in 8% (w/w) lithium chloride/N,N,-dimethylacetamide and the solutions were subjected to size-exclusion chromatography with multi-angle laser-light scattering analysis to determine their molar masses and molar mass distributions...
