Researchers add serum to a classical medium at concentrations of 5 to 10% (v/v) to grow cellsin-vitro culture media. Unfortunately, serum is a poorly defined culture medium componentas its composition can vary considerably while serum-free cell culture media are an excellentalternative to standard serum-containing media and offer several major advantages. Advantagesof us...

  Humans suffer transient or persistent starvation due to a lack of food intake, either because of fasting, voluntary dieting, or due to the scarcity of available food. At the cellular level it is possible to possess pathological starvation during ischemia and solid tumors. Blood provides many nutrients to our cells, and researchers provide these nutrients to cells in culture in the form of en...

background: hyperglycemia is one of the important featurs of diabetes. in cell culture studies different methods are used to mimic the hyperglycemia condition. in this study we investigate response of human liver cancer cell line (hepg2) to high insulin, high glucose, and high insulin/ high glucose medium exposure. methods: hepg2 cells were settled in dmem+0.1% fbs or dmem free-serum medium wit...

abstract   background: regarding the variety of tests present for detecting and also screening prostate cancer and also bearing in mind the advantages and disadvantages of these tests we decided to re-evaluate these tests (total prostate specific antigen and all of its modifications) in detecting prostate cancer in men with intermediate serum psalevels.   methods: following a cross sectional st...

To study the variability of the fraction of CPK released from the infarcted heart which enters the serum (serum entry ratio, or SER) with size and model of infarction, nine dogs underwent homogeneous infarctions (LAD ligation) of varying sizes, and 10 dogs underwent scattered infarctions (left coronary embolization). In homogeneous infarcts there was an inverse linear relationship of SER to inf...

Steady state fluorescence measurements have been used for the investigation of interaction between the bovine serum albumin (BSA) and fluorescence probes: 3-hydroxy-2,4- bis[(3-methyl-1,3-benzoxazol-2(3H)-ylidene)methyl]cyclobut-2-en-1-one (SQ6), 3-hydroxy- 2,4-bis[(3-methyl-1,3-benzothiazol-2(3H)-ylidene)methyl]cyclobut-2-en-1-one (SQ7) and 3-hydroxy-2,4-bis[(1,3,3-trimethyl-1,3-dihydro-2H-ind...

human peripheral blood monocytes (hpbm) were cultured in the absence of human serum and were converted into a state exhibiting a high accessory function expressed by their ability of supporting lymphocyte proliferation. after a prolonged culture in serum free media the monocyte derived cells were highly viable, increased in size and developed veils and dendritiform elongatio'l1s. paralleli...
