Among several adaptive explanations proposed to account for variation in avian egg color, that related to sexual selection is of particular interest because of its possible generality. Briefly, it proposes that because biliverdin (the pigment responsible for blue-green eggshell coloration) is an antioxidant, deposition in the eggshell by laying females may signal the capacity of females to cont...

one hundred and eighty 28-days-old arbor acres broiler birds were utilized in a 28 day experiment to investigate the effect of replacing bone ash with eggshell meal in the diet of broiler birds on their nutrient digestibility and blood parameters. five experimental diets tagged t1, t2, t3, t4 and t5 were formulated to be isocaloric (2865.53 kcal me/kg) and isonitrogenous (20% crude protein) suc...

results there was no statistical difference between the 2 groups with respect to the recurrence rate (p > 0.05). although the recurrence interval was longer for the metformin group, this increase was not statistical significant (p > 0.05). furthermore, tumor recurrence had no correlation with sex or the grade of the tumors. conclusions according to our findings, it seems that metformin has no c...

The formation of coordination polymers (CuCl)P4Se3 (1), (CuBr)3(P4Se3)2 (2), (CuI)3(P4Se3)2 (3) and (CuI)P4Se3 (4), from solutions of copper(I) halides and P4Se3 by diffusion methods has been studied. The new compounds were characterized by X-ray crystallography, solid-state P MAS NMR and Raman spectroscopy. Theoretical studies on the DFT level in the crystalline phase allowed the unequivocal a...

background: metformin is used to lower blood sugar in patients with type ii diabetes. recent research showed that metformin has effects on cancer cell growth. studies show that metformin can induce apoptosis in certain cancer cell lines. in this study, we examined the effect of metformin on apoptosis in the t47d breast cancer cell line. methods : the t47d breast cancer cell line was selected an...

Ever since Czech writer Karel Capek's well-known play " R.U.R. – Rossum's universal robots " [Capek], first published in 1920 and performed in 1921, man-made robots of human-like shape have inspired fiction writers to envision worlds with artificial creatures far superior to human beings – either in friendly coexistence or taking over by eliminating their creators and leaving them behind as an ...

AIMS Increases in the prevalence of type 2 diabetes will likely be greater in the Middle East and other developing countries than in most other regions during the coming two decades, placing a heavy burden on regional healthcare resources. METHODOLOGY Medline search, examination of data from major epidemiological studies in the Middle Eastern countries. RESULTS The aetiology and pathophysio...

Introduction To facilitate radiotracers' development, a screening methodology using a biomathematical model and clinical usefulness index (CUI) was proposed to evaluate radiotracers' diagnostic capabilities. Methods A total of 31 amyloid positron emission tomography radiotracers were evaluated. A previously developed biomathematical model was used to simulate 1000 standardized uptake value ra...

This study evaluated whether metformin might reduce lung cancer risk. The reimbursement database of the Taiwan's National Health Insurance was used. A sample of 15414 never users and 280159 ever users of metformin (original sample) and a 1:1 matched-pairs of ever and never users (n=15414 in each group, matched sample) were recruited from patients with newly diagnosed type 2 diabetes mellitus du...
