Leaves of Maytenus robusta (Celastraceae) were subjected to phytochemical investigation mainly directed at the isolation of pentacyclic triterpenes. The compounds friedelin (1), β-friedelinol (2), 3-oxo-21β-H-hop-22(29)-ene (7), 3,4-seco-friedelan-3,11β-olide (8), 3β-hydroxy-21β-H-hop-22(29)-ene (9), 3,4-seco-21β-H-hop-22(29)-en-3-oic acid (10), 3,4-seco-friedelan-...

In many countries, people are becoming more concerned about pesticide residues which are present in or on food and feed products. For this reason, several methods have been developed to monitor the pesticide residue levels in food samples. In this study, a bioactive paper-based sensor was developed for detection of acetylcholinesterase (AChE) inhibitors including organophosphate and carbamate p...

Alzheimer is an age-dependent disease mostly with genetic origin. In this disorder, acetylcholine is decreased which results in deterioration of short-term memory. Many researches have been focused on finding new sources of medications with more potency and less side effects and investigating acetylcholinesterase inhibitors (AChEIs) has been the center of many researches. In the present study, ...

The clinical evidence for the harmful effect of cortisone on patients infected with tubercle bacilli (American Trudeau Society, 1952; Fred et al., 1951; Traut and Ellman, 1952) has been supported by a series of laboratory studies on mice (Hart and Ress, 1950), rats (Cummings et al., 1952; Michael et al., 1950), guinea pigs (Spain and Molomut, 1950), and rabbits (Lurie et al., 1951). In the prec...

Background: for advance grades of symptomatic hemorrhoids (grade III and IV) the author has innovated a procedure called radiofrequency ablation and fixation of hemorrhoids. The procedure is performed as a day care surgery. Patients and methods: the surgical technique and clinical follow-up of patients operated by this technique are presented. An Ellman dual frequency radiofrequency generator w...

Rheumatoid disease is a systemic disorder, the widespread extra-articular manifestations of which have been reviewed by Dudley Hart (1969, 1970) in his Ellman and Davidson lectures. The tissues clinically involved are those not usually associated with disturbances of metabolism, so that abnormalities of serum chemistry might not be anticipated. Increased use of biochemical investigations in mod...
