Alzheimer᾽s disease is characterized by cognitive deficits, impaired long-term potentiation of learning and memory. A progressive reduction in cholinergic neurons in some areas of the brain such as cortex and hippocampus is related to the deficits in memory and cognitive function in Alzheimer's disease (AD). In the current project a new series of phthalimide derivatives were synthesized. Phthal...

Methods Our study included six patients with acquired infection from central catheter; the microbial pathogens were Streptococcus viridans (n = 3) and Staphyloccocus aureus (n = 3). The diagnosis of IE was based on positive blood culture (2 positive cultures of blood samples drawn > 12 hours), evidence of endocardial involvement (positive ECHO), measuring raised erythrocyte sedimentation rate a...

We report a case of multiple fistulae in ano [8 external openings] in a 45-yrs-old man, who had a history of episodes of pain and pus discharge from openings around the anus since 4 years. Biopsy from the tract of one of the fistula confirmed tubercular infection. He underwent radiofrequency fistulotomy using a Ellman radiofrequency device along with anti-tubercular treatment, which resulted in...

As I have noted, these calculations yield the expected observed accuracy of S s and S c , counting a prediction model as successful when its predictions match the apparent class of new objects. To calculate the accuracy of these strategies in predicting the true class of new objects, simply let n 0 c =0. 8 Acknowledgements Thanks to Tom Ellman, who suggested viewing noise as a model shift in th...

OBJECTIVE To introduce a new simple surgical approach with high-frequency radio-wave electrosurgery to reduce conjunctivochalasis (CCh). DESIGN Prospective, noncomparative, interventional case series analysis. PARTICIPANTS Twelve patients (20 eyes) with CCh were recruited from the outpatient service of the Department of Ophthalmology, Kangbuk Samsung Hospital, Seoul, Korea. METHODS On the...

Background and the purpose of the study: The amount of elder people who suffer from Alzheimer disease is continuously increasing every year. Cholinesterase inhibitors have shown to be effective in alleviating the symptoms of the disease, thus opening a field of research for these treatments. Herbal products, owning a reputation as effective agents in many biological studies are now drawing atte...

The characteristic cutaneous rheumatoid nodule, described fully by Collins (1937) and Bennett, Zeller, and Bauer (1940), is composed of a central area of fibrinoid necrosis around which develops an encircling corona of closely packed mesenchymal cells, the great majority of which appear to be fibroblasts (Collins, 1937), and external to this is a zone of inflammatory tissue. Lesions with simila...
