In spite of rapidly increasing interest in the use of nanoparticle-mediated photothermal therapy (PTT) for treatment of different types of tumors, very little is known on early treatment-related changes in tumor response. Using graphene oxide (GO) as a model nanoparticle (NP), in this study, we tracked the changes in tumors after GO NP-mediated PTT by magnetic resonance imaging (MRI) and quanti...

Different components of the autonomic nervous system may be affected by different disorders to varying degrees. The aim of this study is to report first experiences with a new device (FAN(R), Schwarzer, Germany) which measures heart rate variability (HRV), sympathetic skin responses (SSR) and the pulse wave transit time (PTT). We examined 190 healthy volunteers (102 men, 88 women) and in 89 sub...

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive tumors with low survival rates and the leading cause of death in neurofibromatosis type 1 (NF1) patients under 40 years old. Surgical resection is the standard of care for MPNSTs, but is often incomplete and can generate loss of function, necessitating the development of novel treatment methods for this patient population. Here, w...

BACKGROUND Studies have yet to determine the optimal height at which the posterior tibial tendon (PTT) can be re-routed and the tendon length discrepancy at different height levels in terms of PTT transfer via the circumtibial route. This cadaveric study was conducted to determine the optimal height of PTT subcutaneous transfer and to compare tendon length discrepancies at different heights. ...

An ex vivo photochemical treatment (PCT) process was developed to inactivate pathogens in fresh frozen plasma (PCT-FFP). A prospective, controlled, double-blinded, randomized study was conducted to evaluate the efficacy and safety of PCT-FFP compared with conventional FFP (C-FFP). Patients (n = 121) with acquired coagulopathy, largely due to liver disease, including hepatic transplantation, wer...

The widespread noradrenergic innervation in the brain promotes arousal and learning by molecular mechanisms that remain largely undefined. Recent work shows that the β(2)-adrenergic receptor (β(2)AR) is linked to the AMPA-type glutamate receptor subunit GluA1 via stargazin and PSD-95 (Joiner ML, Lise MF, Yuen EY, Kam AY, Zhang M, Hall DD, Malik ZA, Qian H, Chen Y, Ulrich JD, Burette AC, Weinber...

It has been suggested that the chest-wall (rib-cage, diaphragm, abdominal wall) of a diving animal is nearly incollapsible, and at deep depths can sustain a considerable trans-thoracic pressure PTT (=Pbody surface Pintra-thorax). In strong contrast, we argue on circulatory, blood pooling, biological material strength, and ventilatory grounds that this is incompatible with life. At a PTT of more...

A fosmid library from genomic DNA of Streptomyces viridochromogenes DSM 40736 was constructed and screened for the presence of genes known to be involved in the biosynthesis of phosphinothricin tripeptide (PTT). Eight positives were identified, one of which was able to confer PTT biosynthetic capability upon Streptomyces lividans after integration of the fosmid into the chromosome of this heter...

BACKGROUND While tremor in Parkinson's Disease (PD) can be characterised in the consulting room, its relationship to treatment and fluctuations can be clinically helpful. OBJECTIVE To develop an ambulatory assessment of tremor of PD. METHODS Accelerometry data was collected using the Parkinson's KinetiGraph System (PKG, Global Kinetics). An algorithm was developed, which could successfully ...

Pulse transit time (PTT) is a pivotal marker of vascular stiffness. Because the actual PTT duration in vivo is unknown and the complicated variation in waveform may occur, the robust determination of characteristic point is still a very difficult task in the PTT estimation. Our objective is to devise a method for real-time estimation of PTT duration in pulse wave. It has an ability to reduce th...
