The requirement for correct dosage of the transcription factor Pax6 during corneal growth and development was investigated using the Pax6-overexpressing (PAX77) transgenic mouse. Transgenics had a microcornea phenotype due to failure of postnatal growth, associated with reduction in the number of cells layers in the corneal epithelium. Cell cycle progression was monitored using bromodeoxyuridin...

BACKGROUND The aim of this retrospective study was to explore the relationship between psychotropic medication dosage and birth outcomes. METHODS A total of 136 women were enrolled, who had an active mental disorder, were taking medication to prevent a relapse, or had a history of postpartum depression or psychosis. Medication use was evaluated for the three trimesters and during labor. Based...

Vasoconstriction of the uterine arteries, hypertonus of the uterus, and the direct toxic effects of a local anesthetic on the fetus or a combination of the above have been presented as etiological factors of fetal bradycardia following paracervical block. The reduce fetal side-effects a superficial and lowdosage technique of PCB have been advocated. We have studied the effects of 25 mg of bupiv...

heavy metal contamination in the environment could cause harmful effects both to human health and aquatic life. numerous remediation methods had been developed to encounter with the contamination problem prior to degrade, decrease and to purify the contaminated water at minimal concentration as low as possible. therefore, in current study, commercialized chicken eggshells and hybrid akar putra ...

To obtain insights into similarities and differences in the biological actions of related drugs or toxic agents, their transcriptomal signature profiles (TSPs) have been examined in a large number of studies. However, many such reports did not provide proper justification for the dosage criteria of each agent. Using a well characterized cell culture model of estrogen-dependent proliferation of ...

Diabecon (D-400), a herbal formulation with hypoglycaemic effect, was studied for 12 weeks in 43 patients of maturity-onset diabetes. Diabecon (D-400) significantly reduced fasting (FBS) and twohour postprandial blood sugar (PPBS) in newly diagnosed diabetics and in those already stabilised on antidiabetic medication. Oral hypoglycaemic agents could be omitted in 80% of cases, and the dosage co...

Thirty-one patients with acute cerebral infarction were treated with the thrombolytic agent urokinase for either a single or a double infusion period, each of ten hours. The effects of urokinase therapy administered at dosage rates of 1,200, 1,500 or 1,700 CTA urokinase units per pound of body weight per hour were followed by serial blood coagulation and other biochemical studies. In the dosage...

The genetic basis of hybrid vigor or heterosis has been debated for more than a century. A popular hypothesis to explain this phenomenon is that there are different slightly deleterious recessive homozygous alleles in the two parents and that these alleles are complemented in the hybrid so that the biomass and fertility exceed both parents. To address the complementation hypothesis in a direct ...

It is well established that concentration gradients of signaling molecules (the so-called "morphogens") organize and pattern tissues in developing animals. In particular, studies in Drosophila and different vertebrates have shown that gradients of the Wnt, Hedgehog (Hh) and transforming growth factor-beta (TGF-beta) families of morphogens play critical roles in limb patterning. Morphogens are o...
