BACKGROUND AND PURPOSE An increasing body of literature suggests a role for clinically "silent" cerebrovascular disease in the pathogenesis of cognitive impairment. Such pathology commonly occurs in the absence of stroke. The main aim of the study was to examine neuropsychological impairment associated with cerebrovascular and peripheral vascular disease (PVD) and to compare cognitive deficits ...

When overt pulmonary hypertension arises in interstitial lung disease (ILD), it contributes to exercise intolerance. We sought to determine the functional significance of abnormal pulmonary arterial pressure (PAP) responses to exercise in ILD.27 ILD patients and 11 age-matched controls underwent invasive cardiopulmonary exercise testing (iCPET). Mean PAP (mPAP) was indexed to cardiac output (Q'...

Steganography, derived from Greek, literally means “covered writing”. It includes a vast array of secret communications methods that conceal the message’s very existence. These methods include invisible inks, microdots, character arrangement, digital signatures, covert channels, and spread spectrum communications. This paper proposes a new improved version of Least Significant Bit (LSB) method....

PURPOSE The aim of this study was to evaluate the relationship between oxidative stress and human vitreous degeneration, using the presence of an evident posterior vitreous detachment (PVD) as a clinical sign and thiobarbituric acid-reactive substances (TBARS) and nitrite as oxidative biomarkers. METHODS We collected 42 vitreous samples from patients undergoing pars plana vitrectomy for two g...

In the past several years, monoclonal antibodies have been developed that distinguish between resting and activated platelets in vitro. These antibodies recognize epitopes expressed on membrane proteins or soluble proteins, such as factor XIIIa and thrombospondin, that bind only to activated platelets. We have used fluorescence flow cytometry to determine whether three such antibodies can detec...

Sputtering is an important physical vapor deposition (PVD) method in the manufacture of many products. However, sputtering processes are prone to arcing, which can cause damage to the work piece. Therefore, arcs must be detected and extinguished in a timely manner to minimize damage. Instantaneous arc rate and total arcs per process step are useful data for assessing PVD chamber health, and det...

I discuss the effect of non-radial motions on the small-scale pairwise peculiar velocity dispersions of galaxies (PVD) in a CDM model. I calculate the PVD for the SCDM model by means of the refined cosmic virial theorem (CVT) (Suto & Jing 1997 (hereafter SJ97)) and taking account of non-radial motions by means of Del Popolo & Gambera (1998) (hereafter DG98) model. I compare the results of the p...

MicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expression by post-transcriptional inhibition of mRNA translation. Dysregulation of miRNAs, including circulating miRNAs, has been reported to play an important role in the development of various diseases, including fibrotic diseases. Aberrant expression of miRNAs in the vitreous humor of vitreoretinal diseased eyes has been reporte...

The peripheral nerve pathology in ischaemic limbs with atherosclerotic peripheral vascular diseases (PVD) is difficult to ascertain because of the limited number of reports. In addition, it has been debated whether chronic ischaemia per se could cause morphological abnormalities in peripheral nerves. In this prospective study, we examined pathological findings in the sural, saphenous, deep pero...

Provoked vestibulodynia (PVD) refers to vulvar pain of at least 3 months duration, localized to the vestibule, provoked by touch and sexual activity and occurring in the absence of a clear identifiable cause. The clinical spectrum ranges from mild with distressing discomfort through to severe and disabling pain. Current understanding is that PVD is one of many chronic pain conditions characteri...
