BACKGROUND Advances in techniques have left very few indications for open surgical extraction of urinary stones currently. These advances notwithstanding, the search continues for medical approaches to urinary stone management. In this study, we perform an in vitro study analyzing the efficiency and prospect of two new complex solutions in urological calcium phosphate calculi dissolution. MET...

OBJECTIVE To report preliminary information on urinary stone composition in patients who are either overweight or obese with kidney stone disease. METHODS A cohort of patients (n = 138) with nephrolithiasis were prospectively followed from January 2011 for 18 months. Of those, 64 (46%) were found to be overweight with body mass index ≥ 25 kg/m(2) and 74 (54%) were obese with body mass index ≥...

this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...

To get complete information about the chemical composition and physicochemical principles underlying the formation of stone there is a need for more precise information. At present there is no single analytical procedure that provides an exact quantitative analysis of urinary calculi. In this present procedure it is assumed that only calcium oxalate monohydrate, hydroxyapatite, or magnesium amm...

Received 7, December, 2014 Received in revised form 19, December, 2014 Accepted 10, January, 2015 Published online 28, January, 2015 The gall stone formation (cholelithiasis) is well known global health problem since very early times. Various biochemical and patho-physiological factors have been reported to be associated with gall stone disease such as stasis of bile, obstruction in bile duct, ...

Stone tool transport leaves long-lasting behavioural evidence in the landscape. However, it remains unknown how large-scale patterns of stone distribution emerge through undirected, short-term transport behaviours. One of the longest studied groups of stone-tool-using primates are the chimpanzees of the Taï National Park in Ivory Coast, West Africa. Using hammerstones left behind at chimpanzee ...

Capuchins living in Boa Vista (Piauì, Brazil) crack open hard palm nuts on hard, level surfaces (anvils) using stones (hammers) as percussive tools. This activity leaves diagnostic physical remains: distinctive shallow depressions (pits) on the surface of the anvil, cracked shells, and stone hammers on the anvil. To initiate comparison of percussive stone tool use and interpretation of the arti...

We prove that every continuum of weight א1 is a continuous image of the Čech-Stone-remainder R of the real line. It follows that under CH the remainder of the half line [0,∞) is universal among the continua of weight c. We complement this result by showing that 1) under MA every continuum of weight less than c is a continuous image of R, 2) in the Cohen model the long segment of length ω2 + 1 i...
