Lipoma is a common soft-tissue tumor. There are only very few reported cases of intraosseous lipoma of the jaws in the literature. Intraosseous angiolipomas are even rarer. The exact nature of these lesions is debatable, but it is widely accepted that they represent true benign tumors. These are slow-growing tumor consisting of a mass of mature fat cells.(More)
Poly(ADP-ribose) polymerase-1 (PARP-1) (ADP, adenosine diphosphate) has a modular domain architecture that couples DNA damage detection to poly(ADP-ribosyl)ation activity through a poorly understood mechanism. Here, we report the crystal structure of a DNA double-strand break in complex with human PARP-1 domains essential for activation (Zn1, Zn3, WGR-CAT).(More)
The growing prevalence of broadband Internet access around the world has made understanding the performance and reliability of broadband access networks extremely important. To better understand the performance anomalies that arise in broadband access networks, we have deployed hundreds of routers in home broadband access networks around the world and are(More)
In the small intestine, epithelial cells are derived from stem cells in the crypts, migrate up the villus as they differentiate and are ultimately shed from the villus tips. This process of proliferation and shedding is tightly regulated to maintain the intestinal architecture and tissue homeostasis. Apoptosis regulates both the number of stem cells in the(More)
Villin is a tissue-specific, actin-binding protein involved in the assembly and maintenance of microvilli in polarized epithelial cells. Conversely, villin is also linked with the loss of epithelial polarity and gain of the mesenchymal phenotype in migrating, invasive cells. In this study, we describe for the first time how villin can switch between these(More)
BACKGROUND Delivery of essential newborn care is key to reducing neonatal mortality rates, yet coverage of protective birth practices remains incomplete and variable, with or without skilled attendance. Evidence of changes over time in newborn care provision, disaggregated by care practice and delivery type, can be used by policymakers to review efforts to(More)
BACKGROUND The aim of the present article is to report a case of ameloblastic carcinoma and use a marker alpha smooth muscle actin as a tool to differentiate cases of ameloblastic carcinoma from that of ameloblastoma. METHODS Case study reporting a case of ameloblastic carcinoma (AC) with expression of alpha smooth muscle actin (alpha-SMA) as a marker for(More)
OBJECTIVE Keratocystic odontogenic tumor (KCOT) has an aggressive clinical course and a high tendency of recurrence, while orthokeratinized odontogenic cyst (OOC) has different characteristics and does not show aggressive behaviour. Even the treatment of these two lesions varies considerably. A large number of epithelial molecules have been studied in order(More)
