A variety of neurological disorders and polyglutamine (polyQ) diseases are caused by misfolded proteins. The common feature of these diseases is late-onset cellular degeneration that selectively affects neurons in distinct brain regions. polyQ diseases, including Huntington's disease (HD), present a clear case of selective neurodegeneration caused by polyQ expansion-induced protein misfolding, ...

Ubiquitin-proteasome system (UPS) mediated proteolysis is responsible for the degradation of majority of cellular proteins, thereby playing essential roles in maintaining cellular homeostasis and regulating a number of cellular functions. UPS dysfunction was implicated in the pathogenesis of numerous disorders, including neurodegenerative disease, muscular dystrophy, and a subset of cardiomyopa...

Alterations in cellular structure and synapse composition are central to proper nervous system function. Recent work has identified the ubiquitin-proteasome system (UPS) as a key regulator of neuronal biology. The UPS is essential for the growth and development of immature neurons and is a critical mediator of synaptic adaptability in mature neurons. Furthermore, proteinaceous deposits that acc...

BACKGROUND Alexithymia is thought to be associated with the development of medically unexplained physical symptoms (UPS). So far little research has been published on alexithymia as a risk factor for the persistence of UPS. OBJECTIVE To determine the clinical outcome in UPS patients and to study the relative importance of alexithymia in predicting that outcome. METHODS A follow-up study was...

Postoperative epidural analgesia often needs rate readjustment using top-ups. Patient-controlled epidural analgesia (PCEA) is said to reduce the requirement of epidural top-ups when compared to continuous epidural analgesia (CEA). We compared CEA and PCEA in major thoracic and abdominal surgery, in a cohort study. The primary endpoint was the required number of epidural top-ups. Secondary endpo...

New technology based start-ups play a very important role in developing the economy of a country. In India, telecom sector has seen unprecedented growth over the last decade and this has led to emergence of several telecom related start-ups. However, product based B2B start-ups are rare and existing ones have to undergo several challenges in commercializing. Surprisingly not much research work ...

The topic of distinguishing atypical fibroxanthoma (AFX) from undifferentiated pleomorphic sarcoma (UPS), formerly malignant fibrous histiocytoma, is highly controversial. Although their clinical behavior is disparate, AFX and UPS commonly appear nearly identical on routine histopathologic examination. Although conceptually useful, subcategorization of UPS into superficial (confined to the derm...

Surface nanostructuring enables the fabrication of materials with highly desirable properties. Nanostructured tungsten surfaces have potential applications in solar water splitting. Exposing a polished surface to helium plasma induces various morphological changes. Depending on ion energy, temperature, and fluence, clusters, bubbles foam-like nanostructures develop surface. In this study, were ...
