479 and XIIIa. Low-grade myxofibrosarcoma is positive for vimentin, but it is negative for CD34 and desmin. Myxoid neurofibroma is a tumor of neural origin, showing positive immunohistochemistry for S100, which is of help in making a differential diagnosis of SAF [1-5]. It is known that SAF has a benign natural course, for which the standard treatment modality is complete surgical removal. Inco...

The 263K strain of scrapie in hamsters (1,2) has become the most important system for experimental research aimed at discovering the slow unconventional agent which natural ly causes the chronic subacute spongiform encephalopathy 'scrapie' in sheep (3). Other unidenti f ied but similar agents cause similar diseases in man (#), mink (3), and captive mule deer (5). In 1981 P. Merz et al. for the ...

BACKGROUND Advanced glycation end products are involved in the vascular complications of diabetes, in chronic kidney disease, and in the aging process. Their accumulation in the elderly people, as reflected by skin autofluorescence (sAF), may be a marker of metabolic memory. We aimed to examine the association of sAF with glycemic and renal status 10 years earlier in older persons. METHODS In...

We are developing hollow fiber-based specific antibody filters (SAFs) that selectively remove antibodies of a given specificity directly from whole blood, without separation of the plasma and cellular blood components and with minimal removal of plasma proteins other than the targeted pathogenic antibodies. A principal goal of our research is to identify the primary mechanisms that control anti...

OBJECTIVE The present study investigated the antioxidant, antiglycation and inhibitory potential of flavonoid fraction of Saraca ashoka flowers (SAF) against alpha-glucosidase and alpha-amylase (the enzymes linked to type 2 diabetes) and LDL oxidation. MATERIALS AND METHODS Antioxidant capacity of SAF was evaluated by estimating total antioxidant activity (TAA) and its protective effects agai...

Pseudomonas aeruginosa (PA) and Staphylococcus aureus (SA) are major respiratory pathogens and can concurrently colonize the airways of patients with chronic obstructive diseases, such as cystic fibrosis (CF). Airway epithelial cell signalling is critical to the activation of innate immune responses. In the setting of polymicrobial colonization or infection of the respiratory tract, how epithel...

Safinamide (SAF) is a new drug developed for the treatment of Parkinson's disease (PD). It is a benzylamino derivative with multiple mechanisms of action and antiparkinsonian, anticonvulsant, and neuroprotective properties. SAF inhibits monoamine oxidase B and dopamine reuptake and glutamate release, blocks voltage-dependent sodium channels, and modulates calcium channels. Although the antipark...

Secalonic acid F (SAF) has been previously identified, however, little is known about its cytotoxic activity and related cytotoxic mechanism. The aim of this study was to evaluate the cytotoxic activity of SAF isolated from a deep sea originated fungus Penicillium sp. F11 in HL60 cells and to analyze the differences in protein expression of HL60 c...

We previously identified the heterogeneous ribonucleoprotein SAF-A/hnRNP U as a substrate for DNA-PK, a protein kinase involved in DNA damage response (DDR). Using laser micro-irradiation in human cells, we report here that SAF-A exhibits a two-phase dynamics at sites of DNA damage, with a rapid and transient recruitment followed by a prolonged exclusion. SAF-A recruitment corresponds to its bi...

Apoptosis is a morphologically distinct form of cell death involved in many physiological and pathological processes. The regulation of Fas/Apo-1 involved in membrane-mediated apoptosis has also been known to play crucial roles in many systems. More and more naturally occurring antisense RNAs are now known to regulate, at least in part, a growing number of eukaryotic genes. In this report, we d...
