Microcrystalline cellulose acetate (MCC) was incorporated in poly (ethylene-co-vinyl acetate) (EVA) at different loading. The morphology, swelling properties and drug release profile were studied with respect to MCC loading to study its potential application as ocular inserts. The XRD patterns showed a good compatibility between the components. However swelling ratio and in-vitro degradation of...

BACKGROUND A new virus called the Merkel Cell Polyomavirus (MCPyV) has recently been found in Merkel Cell Carcinoma (MCC). MCC is a rare aggressive small cell neuroendocrine carcinoma primarily derived from the skin, morphologically indistinguishable from small cell lung carcinoma (SCLC). So far the actual presence of the virus in MCC tumour cells on a morphological level has not been demonstra...

Acute inhalations of beta 2-adrenergic receptor agonists increase mucociliary clearance (MCC). Less is known about the effect of long-term inhalations of these agents on MCC, or cough clearance (CC). We hypothesized that chronic inhalations of nebulized levalbuterol, the R-isomer of albuterol, would enhance MCC and/or CC in healthy subjects, compared to albuterol or placebo. This was a randomiz...

The Saccharomyces cerevisiae plasma membrane has been proposed to contain two stably distributed domains. One of these domains, known as MCC (membrane compartment of Can1) or eisosomes, consists of furrow-like membrane invaginations and associated proteins. The other domain, called MCP (membrane compartment of Pma1), consists of the rest of the membrane area surrounding the MCC patches. The rol...

BACKGROUND Merkel cell polyomavirus (MCV) was discovered by digital transcriptome subtraction as a monoclonal infection of Merkel cell carcinoma (MCC) tumors. Subsequent studies have repeatedly confirmed that MCV is the likely cause for most MCC. Polymerase chain reaction-based detection of the virus in other nonmelanoma skin cancers, however, has been inconsistent and controversial. OBJECTIV...

Merkel cell carcinoma (MCC) is a rare potentially fatal skin tumor affecting older and immunosuppressed individuals. It is highly malignant with high rates of metastasis and poor survival.We present a case of a 67-year-old woman with a palpable mass in the upper abdomen. An abdominal CT revealed a mass in the tail of the pancreas. Two weeks before, lumpectomy of a 3.5 cm tumor of the left breas...

Merkel cell carcinoma (MCC) is one of the most aggressive cancers of the skin. RASSFs are a family of tumor suppressors that are frequently inactivated by promoter hypermethylation in various cancers. We studied CpG island promoter hypermethylation in MCC of RASSF2, RASSF5A, RASSF5C and RASSF10 by combined bisulfite restriction analysis (COBRA) in MCC samples and control tissue. We found RASSF2...

Influence of some commercially available types of microcrystalline cellulose (MCC) on the stability of certain active pharmaceutical ingredients (APIs), when in contact, has been investigated. Two structurally similar APIs, perindopril erbumine (PER) and enalapril maleate (EM), both well-known angiotensin-converting enzyme inhibitors were used. The main properties of an MCC that could determine...

The multiple choice cloze (MCC) question format is commonly used to assess students' comprehension. It is an especially useful format for ITS because it is fully automatable and can be used on any text. Unfortunately, very little is known about the factors that influence MCC question difficulty and student performance on such questions. In order to better understand student performance on MCC q...

Merkel cell carcinoma (MCC) is an uncommon cutaneous malignant tumor that presents as a rapidly growing skin nodule on sun-exposed areas of the body. MCC is aggressive with regional nodal and distant metastases to the skin, lung, and bones. There have been no reports of metastatic MCC to the mesentery and 6 reports describing metastasis to the small intestine. We present a case of metastatic MC...
