O Cerrado brasileiro possui uma grande diversidade florística ainda pouco estudada sobre os efeitos e possíveis atividades biológicas de interesse humano, como a inibição da acetilcolinesterase (AChE). Extratos florais liofilizados diferentes espécies vegetais produzidos entre 2017-2022, mantidos -12 °C, foram utilizados. método utilizada, foi proposto por Ellman, modificado Miloševića colabora...
Thiols play vital roles in cellular metabolism knowledge of which may be important the design future anticancer drugs. Previous work on composition thiols present human cancer cell lines has shown presence an unknown low molecular weight species, deemed to a “Conthiol”, could this respect. This was prepared and isolated from prostate line (LNCaP) form adduct 2-mercuri-4-nitrophenol; it accounts...
The purpose of the present study was to employ two methods-square wave voltammetry (SWV) performed on screen printed sensors and ferric reducing antioxidant power (FRAP)-as suitable tools for the assay of low-molecular-weight antioxidants (LMWAs). LMWAs were assayed by both methods and the resulting data were statistically compared. Plasma samples from five Cinereous vultures accidentally intox...
INTRODUCTION Malathion is one of organophosphate poisons (OPPs) that inhibit cholinesterase activity and induce oxidative stress in target organs, such as the reproductive system. The aim of this study was to assess the effects of Malathion on serum and erythrocyte cholinesterase activity in male rats and also to assess the protective effects of vitamin C in this regard. METHODS This experime...
ObjectivesTo study the long-term effect of tonsillotomy and tonsillectomy in young children after two years in comparison to the results after six months.MethodChildren, age 4-5 with Sleep Disordered Breathing (SDB) and tonsil hyperplasia, were randomized to TE (32) or TT (35). TT was performed ad modum Hultcrantz with radiofrequency technique (Ellman). An adenoidectomy with cold steel was perf...
The 30 cases of essential pulmonary haemosiderosis hitherto published supply ample data to present not only the classical pattern of this disease but also its latent form. The condition mostly affects children; in adolescents (16 to 20 years of age) it was observed in two instances only (Waldenstrom, 1944; Walton and Williams, 1951) and the true nature of the adult cases reported by BorsosNacht...
Data on blood cholinesterase levels in the Malaysian population is lacking. The spectrophotometric method of Ellman was used to determine the red cell, plasma and whole blood cholinesterase (ChE) levels in 407 Malaysian blood donors. The mean+1SD for plasma ChE in females (n = 48) was 2.37 + 0.70 umol/min/ml and 2.76 + 0.75 umol/min/ml in males (n = 359). The mean plasma ChE in males was higher...
BACKGROUND Alzheimer's disease (AD) is a progressively developing neurodegenerative disorder of the brain in the elderly people. Vanda roxburghii Rbr. root has been used traditionally in Bangladesh as tonic to brain and in the treatment of nervous system disorders including AD. Therefore, we aimed to investigate the cholinesterase inhibitory activities and antioxidant properties of the extracts...
In a study of transaminase systems Braunstein (1) learned that cr-aminoadipic acid takes part in transamination. Both pigeon breast muscle mince and a purified glutamic transaminase extracted from it were active in transferring an amino group from alanine to a-ketoadipic acid. A plant aspartic transaminase was inactive with the same substrate. Experiments by Borsook and Dubnoff (2) on the synth...
BACKGROUND Human butyrylcholinesterase (huBChE) has been shown to be an effective antidote against multiple LD50 of organophosphorus compounds. A prerequisite for such use of huBChE is a prolonged circulatory half-life. This study was undertaken to produce recombinant huBChE fused to human serum albumin (hSA) and characterize the fusion protein. RESULTS Secretion level of the fusion protein p...
