The aim of the present study is to determine whether patients with primary spontaneous pneumothorax (PSP) are subject to oxidative stress. For this purpose, we measured the activities of red blood cell superoxide dismutase, which is an antioxidant enzyme, and the level of plasma malondialdehyde, which is one of the lipid peroxidation markers, in a group of patients with PSP. The study was carri...

Progressive supranuclear palsy (PSP) with predominant cerebellar ataxia (PSP-C) is a rare phenotype of PSP. The clinical and radiological features of this disorder remain poorly characterized. Through a retrospective case series, we aim to characterize the clinical and radiological features of PSP-C. Four patients with PSP-C were identified: patients who presented with prominent cerebellar dysf...

A 67-year-old woman presented with falls, cognitive impairment, mild upgaze palsy and parkinsonism for 3 years. A MRI was unremarkable. A PET-CT with fluorodeoxyglucose (FDG) disclosed reduced metabolism in thalami, midbrain and frontal cortex (Figure 1), suggesting progressive supranuclear palsy (PSP). Posterior MRI showed typical features observed in PSP (Figure 2). PSP is a neurodegenerative...

The Personal Software Process (PSP) is a framework for individual software engineers to improve the quality, predictability and productivity of their work. It consists of a family of seven personal processes that progressively introduce data collection and analysis techniques. This paper presents a PSP tool that is integrated into the Eclipse environment. Currently it includes an Eclipse plug-i...

Ovulation and pseudopregnancy (psp) can be induced by cervical stimulation in persistent estrous rats maintained in a constant lighting condition (LL-psp rats). Different from the pattern of prolactin (PRL) secretion in usual psp rats maintained in a daily light-dark cycle (LD-psp rats), PRL secretion in these rats during the psp period does not occur in the form of two daily surges. The object...

Purpose Progressive supranuclear palsy (PSP) is an akineticrigid syndrome that can be difficult to differentiate from Parkinson’s disease (PD), particularly at an early stage. [Tc]ethyl cysteinate dimer (ECD) SPECT could represent a widely available tool to assist in the differential diagnosis. In this study we used voxel-based analysis and Computerised Brain Atlas (CBA)-based principal compone...

BACKGROUND Clinical features suggesting a diagnosis of progressive supranuclear palsy (PSP) include early falls, axial rigidity, vertical supranuclear ophthalmoplegia, and levodopa unresponsiveness. When these clinical features are present, the diagnosis is almost always PSP, yet vascular disease sometimes has a similar presentation, referred to as vascular PSP. OBJECTIVE To evaluate clinical...

By exploiting our recently derived exact formula for the Lindhard polarization function in the presence of Bychkov-Rashba BR and Dresselhaus D spin-orbit interaction SOI , we show that the interplay of different SOI mechanisms induces highly anisotropic modifications of the static dielectric function. We find that under certain circumstances the polarization function exhibits doubly singular be...

Circuit simulation model for advanced SOI-MOSFETs has been developed by solving Poisson’s equation consistently. It is successfully proven that, as a result of solving the Poisson’s equation considering its device structure, our model is applicable for various variations of SOI-MOSFETs such as partially depleted (PD), fully depleted (FD) and dynamically depleted SOI-MOSFETs, which is the indisp...

We present a new approach to remove monolayer graphene transferred on top of a silicon-on-insulator (SOI) photonic integrated chip. Femtosecond laser ablation is used for the first time to remove graphene from SOI waveguides, whereas oxygen plasma etching through a metal mask is employed to peel off graphene from the grating couplers attached to the waveguides. We show by means of Raman spectro...
