background: it has been reported that the chronic oral administration of garlic homogenate protected the rat heart from in vitro ischemic reperfusion injury. however, the biological effects of garlic juice on the heart are expected to be different from oral administration of it. objective: the present study was designed to investigate the effect of garlic juice on the isolated rat heart in isch...

here, we have synthesized vertically aligned carbon nanotubes (va-cnts), using chemical vapor deposition (cvd) method. cobalt and ethanol are used as the catalyst and the carbon source, respectively. the effects of ethanol flow rate, thickness of co catalyst film, and growth time on the properties of the carbon nanotube growth are investigated. the results show that the flow rate of ethanol and...

tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. on the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant e. coli, and consequently fed-batch culture have received less attention....

Growth at the proximal tibial epiphyseal plate of the rat has been measured following three different growth-stimulating procedures. These were proximal periosteal release, distal periosteal release and full periosteal stripping of the diaphysis. A new radiographic method using a photographic technique has made it possible to take accurate measurements of the rate of long-bone growth in small e...

The growth of the R3327-G rat prostatic adenocarcinoma was significantly reduced when implanted in orchiectomized male rats (ORCH tumors). Tumors grown in intact animals (control tumors) had a doubling time of 7.4 days as compared to 9.2 days in ORCH tumors. A computer-based analysis of flow cytometric DNA histograms also detected significant dif ferences between control and ORCH tumors. ORCH t...

Clonal cell lines were derived from rat liver epithelial cells following their transformation with either v-raf or v-raf/v-myc. Cells transformed with v-raf alone showed reduced tumor incidence and tumor growth rates when implanted into nude mice, compared to cells also expressing the v-myc oncogene. A series of additional clones isolated from a tumor obtained following inoculation of an athymi...

BACKGROUND The adverse effects of cigarette smoking on human fertility have been well documented. However, the mechanism(s) underlying the detrimental effects of cigarette smoking are unknown. Using a novel isolated rat follicle culture assay, we tested the hypothesis that benzo-[a]-pyrene (B[a]P), a constituent of cigarette smoke, can inhibit follicle growth. METHODS B[a]P levels were quanti...

The influence of sympathetic innervation on the growth and intrinsic rate of beating established by fetal rat heart was studied by culturing fetal atrial tissue in sympathetically innervated and denervated anterior eye chambers of adult Sprague-Dawley rats. One anterior eye chamber in each host rat was sympathetically denervated by removing the ipsilateral superior cervical ganglion. In oculo, ...
