In vitro studies on cancer cell lines still constitutes a major part of cancer research. It is very important that the researchers consider the importance of basic conditions of working with different cell lines. To the best of authors knowledge, this study is the first one to report the effect of seeding density on the growth curve of three human cancer cell lines. These cell lines include hum...

In this contribution, linearized dynamic model of Cumulative Mass Fraction (CMF) of Potassium Nitrate-Water Seeded Continues Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer is approximated by a simplified model in frequency domain. Frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. However, the CM...

tillage and press wheel weight play an important role in seedling emergence, crop establishment and growth. an optimal combination of tillage implements and suitable press wheel weights should increase grain yield. this study investigated the effect of tillage systems and press wheel weights on dry land wheat (triticum aestivum l.) seedling emergence and grain yields in izeh, khuzestan province...

The consideration of virulence must distinguish between infectivity and the ability to cause progressive disease once the infection is established. Several investigators have reported the presence of naturally occurring isolates which differ in virulence for guinea pigs. Isolates from south India which differed with respect to gross disease and number of bacilli recovered from spleen after an i...

background: despite major progress in our general knowledge related to the application of adult stem cells, finding alternative sources for bone marrow mesenchymal stem cells (mscs) has remained to be challenged. in this study successful isolation, multilineage differentiation, and proliferation potentials of sheep mscs derived from bone marrow, adipose tissue, and liver were widely investigate...

introduction: meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. it can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. as a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. trauma and viruses are possible e...

In Experiment 1, five adult female impala were fitted with harnesses that restrained oral self-grooming of the anterior part of the body. At the same time, six cohoused female impala were fitted with control harnesses that allowed normal oral grooming. The impala were allowed to habituate to the harnesses for 10 days, and both groups were then exposed to larval ticks (Boophilus decoloratus) by ...

We have demonstrated a 0.7 microm - 1.9 microm wavelength-tunable light source based on a single-pass optical parametric amplification (OPA) in a multiperiod magnesium oxide-doped periodically poled lithium niobate crystal. The OPA pump was a frequency-doubled ultrafast ytterbium-doped fiber oscillator, and the residual 1040 nm laser power after frequency doubling was recycled to generate a sup...
