BACKGROUND Decompressive hemicraniectomy (DHC) is a life-saving procedure for treatment of large malignant middle cerebral artery (MCA) strokes. Post-stroke epilepsy is an additional burden for these patients, but its incidence and the risk factors for its development have been poorly investigated. OBJECTIVE To report the prevalence and risk factors for post-stroke seizures and post-stroke ep...

Retroviral capsid (CA) cores undergo uncoating during their retrograde transport (toward the nucleus), and/or after reaching the nuclear membrane. However, whether HIV-1 CA core uncoating is dependent upon its transport is not understood. There is some evidence that HIV-1 cores retrograde transport involves cytoplasmic dynein complexes translocating on microtubules. Here we investigate the role...

This paper describes our experience in using a multimedia project management and software engineering environment, Decision-based Hyper-multimedia CASE (DHC), to support the Low-Visibility Landing and Surface Operations (LVLASO) project at the NASA Langley Research Center. 1 The purpose of the LVLASO project is to allow pilots to land and taxi airplanes when visibility is impeded due to adverse...

BACKGROUND Decompressive hemicraniectomy (DHC) reduces mortality and improves outcome after malignant middle cerebral artery infarction (MMI) but early in-hospital mortality remains high between 22 and 33%. Possibly, this circumstance is driven by cerebral herniation due to space-occupying brain swelling despite decompressive surgery. As the size of the removed bone flap may vary considerably b...

Cholesterol is the most representative sterol present in vertebrate membranes and is the end product of the long and multistep sterol biosynthetic pathway. 7-Dehydrocholesterol (7-DHC) and desmosterol are the immediate biosynthetic precursors of cholesterol in the Kandutsch-Russell and Bloch pathway. In this article, we have monitored the effect of cholesterol and its two immediate biosynthetic...

BACKGROUND Little if any cutaneous production of vitamin D3 occurs at latitudes above and below 35° N and 35° S during the winter months. It was postulated that those residing in tropics synthesize enough vitamin D3 year round. Several studies have documented the effect of latitude, season and time of the day on the cutaneous production of vitamin D3 in an ampoule model. Studies from India have...

BACKGROUND There is controversy as to whether coumarin, an ingredient in cosmetics and fragrances, is a contact allergen involved in fragrance allergy. We recently showed that the purity of coumarin is a critical parameter for its allergenicity because coumarin preparations containing trace amounts of contaminants induced cell proliferation in the local lymph node (LN) assay whereas pure coumar...

Human skin, and its isolated cells, respond to insults with a variety of repair and protective mechanisms. One such mechanism is the production of heat shock proteins (HSPs). Heat shock proteins help the other cellular proteins fold correctly into their active three-dimensional structures. Therefore, they can enhance the survival of cells under harsh, denaturing conditions. In order to develop ...

INTRODUCTION The aim of this study was to evaluate the effect of malocclusion severity on oral health-related quality of life and food intake ability in adult patients, controlling for sex, age, and the type of dental clinic visited. METHODS The sample consisted of 472 Korean patients (156 male, 316 female) with a mean age of 21.1 (SD, 8.6) years in a dental hospital and a private clinic. The...
