the most frequently mutated tumor suppressor gene found in human cancer is p53. in a normal situation, p53 is activated upon the induction of dna damage to either arrest the cell cycle or else induce apoptosis. however, when mutated, p53 is no longer able to properly accomplish these functions. our aim was to investigate p53 protein alteration in cases of basal cell carcinoma (bcc) and compare ...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

Microtubules have important roles in intracellular trafficking. The targeted transport of cellulose synthase along microtubule tracks determines the orientation of cellulose microfibrils and hence influences cell shape and elongation (Lloyd, 2006; Paredez et al., 2006). The ability of microtubules to alter their cellular layout in response to various stimuli is central to their function. In the...

in order to determine the value of dipstick analysis of urinary protein in pregnancy induced hypertension, a prospective study analyzing pregnant patients with a diagnosis of hypertensive disorder was conducted to compare the result of urinary protein dipstick analysis with 24hr. urine protein collection in obstetrical clinics affiliated to shiraz university of medical sciences. all patients fu...

conclusion: the newly produced recombinant protein bmk revealed to be immunogenic. moreover, anti-bmk antibodies produced in mice were able to recognize both the recombinant bmk neurotoxin and the one in m. eupeus crude venome. taken together, the molecular characterization and recombinant production of the iranian scorpion m. eupeus venom component can serve as a new probe for further studies ...

sepsis is a significant health problem with an estimated 750,000 new cases in the usa annually. it is also the third leading cause of death in developed countries, equaling the number of fatalities from acute myocardial infarction. the high sepsis-related mortalities mean there is an urgent need to improve the diagnosis and management of sepsis patients. the aim of this study was the evaluation...

in the present study, we investigated total cell protein patterns of ten isolates of epidermophyton floccosum var.pigmented by sds-page on 10% polyacrylamide resolving gels. densitometric analysis of the gels allowed to detect more than 31 clearly detectable mycelial protein bands with molecular weights in the range of 12 to 98 kd proteins of 12.5, 13.5, 14.4, 16, 18.4, 19.7, 20.1, 23.5, 26, 27...

castor bean, peanut, soy bean and safflower protein isolates were prepared. the amino acid content of each of the protein isolates was analysed and the essential amino acid contents were compared with the fao human requirements. the results indicated that castor bean has the highest oil and the protein content of defatted meal. safflower 3148 (marand, iran) has the highest amount of essential a...

abstract         background and objective: hirudin is an anticoagulant polypeptide secreted from the salivary glands of leeches. recombinant hirudin is a strong anticoagulant agent in arterial and venous thrombosis. the aim of this study was to evaluate the effect of inserting protein a signal peptide sequence of pezz18 plasmid on expression and secretion of the recombinant hirudin in e.coli.  ...

the aim of this study was to compare three routine precipitation methods, including: acetone, tca/acetone wash and tca/acetone. 30 plasma samples were precipitated using above mentioned three methods. pellets were dissolved in rehydration solution and protein quantification was done for this solution. according to statistical analysis using spss ver 16.0 software and one-way anova test, the pro...
