~~IGI-IT, FRED s. Increasing magnitude of electrical potential along the renal distal tubule. Am. J. Physiol. 220(3): 624-638. 1971.The magnitude of the transepithelial electrical potential (PD) was examined along the length of the distal tubule of rats. To determine whether the PD is constant along the length of the tubule, several methods were used to identify distance from the beginning of t...

BACKGROUND An estimated 30-50% of essential tremor (ET) diagnoses are incorrect, and the true diagnosis in those patients is often Parkinson's disease (PD) or other tremor disorders. There are general statements about the tremor in these ET and PD, but published data on the more subtle characteristics of tremor are surprisingly limited. Postural tremor may occur in both disorders, adding to the...

Angiosarcomas are rare malignant endothelial-cell tumors of vascular or lymphatic origin, and are among the most aggressive subtypes of soft-tissue sarcomas. The prognosis is poor and treatment is challenging in many cases. PD-1/PD-L1 pathway plays a critical role in immune escape of tumor cells. Recent studies described that PD-L1 is widely expressed in various types of cancer, providing the b...

Different types of classifiers for acoustic partial discharge (PD) pattern classification have been widely discussed in the literature. The classifier performance mainly depends on measurement conditions (location and type PD, sensor position frequency response) as well extracted features. Recent research posits that features by singular value decomposition (SVD) can exhibit natural characteris...

Bifunctional catalysts containing a dehydrogenation–hydrogenation function and an acidic are widely applied for the hydroconversion of hydrocarbon feedstocks obtained from both fossil renewable resources. It is well known that distance between two functionalities important performance catalyst. In this study, we show heat treatment catalyst precursor can be used to steer location Pd with respec...

OBJECTIVE Deep brain stimulation (DBS) has been used for more than a decade to treat Parkinson's disease (PD); however, its mechanism of action remains unknown. Given the close proximity of the electrode trajectory to areas of the brain known as the "germinal niches," we sought to explore the possibility that DBS influences neural stem cell proliferation locally, as well as more distantly. ME...

Parkinson’s disease (PD) is a progressive and chronic nervous system disease that impairs the ability of speech, gait, and complex muscle-and-nerve actions. Early diagnosis of PD is quite important for alleviating the symptoms. Cost effective and convenient telemedicine technology helps to distinguish the patients with PD from healthy people using variations of dysphonia, gait or motor skills. ...

The specific aspects of cognition contributing to balance and gait have not been clarified in people with Parkinson's disease (PD). Twenty PD participants and twenty age- and gender-matched healthy controls were assessed on cognition and clinical mobility tests. General cognition was assessed with the Mini Mental State Exam and Addenbrooke's Cognitive Exam. Executive function was evaluated usin...
