Introduction. Several studies showed an association of overweight and obesity with calcium oxalate stone disease (CaOx). However, there are no sufficient data on the influence of body weight on the course of the disease and the recurrence rate. Patients and Methods. N = 100 consecutive stone formers with pure CaOx were studied. Different parameters were investigated. According to the BMI, patie...

Recently, Bennett, English and Talanda-Fisher introduced the vertex-induced weighted Turán problem. In this paper, we consider their open problem under sum-edge-weight function characterize extremal structure of K ℓ -free graphs. Based on these results, propose a generalized version Erdős–Stone theorem for graphs two types weight functions.

which are quite intelligible to an old hand in the game. His article suggests to me a few points of general interest. Sounding for Stone.?You can detect a large stone with any instrument you pass. It is the small ones of a few grains weight which are of interest. I have frequently failed to sound them in a patient, anaesthetised and with the bladder distended, with a sound. The moment I passed ...

Archaeologists are increasingly in need of quantitative measures of stone artefact retouch. Existing techniques fail to provide a generic measure of retouching for all chipped stone artefacts. A fast and reliable index is proposed which measures retouch in terms of the invasiveness of flake scars on the surfaces of complete stone artefacts. Unlike other measures, the index of invasiveness is we...

OBJECTIVE To examine whether hypertension predicts the incidence of kidney stone disease. DESIGN Prospective cohort study (the Olivetti Prospective Heart Study). SETTING The Olivetti factory in Southern Italy. SUBJECTS Five hundred and three male workers, aged 21 - 68 years, with no evidence of kidney stone disease at baseline. Follow-up 8 years. MAIN OUTCOME MEASURES Anthropometry, blo...

hairball in a urethral diverticulum has rarely been reported. these hairballs are usually formed in the diverticulum coated with a hair bearing epithelium and can lead to urinary obstruction or infection. using laser is a safe way to ablate such stones.

BACKGROUND Outcome of Extracorporeal Shockwave Lithotripsy (SWL) is determined by physical factors that affect stone fragmentation and clearance. PURPOSE To evaluate the predictive value of the Lithotripsy Table Height (LTH) in SWL outcome. Lithotripsy Table Height (LTH) is a variable that represents skin to therapy head distance, and it is proportional to the energy that reaches the stone. ...

BACKGROUND Percutaneous nephrolithotomy (PCNL) has been widely used to treat renal stones. The application of PCNL in obese patients results in the emergence of a number of challenges. This study compared the effect of obesity on the outcomes of PCNL in kidney stone treatment. METHODS Eligible studies were searched in PubMed, Web of Science, and Cochrane Library databases. Data were analyzed ...

This article focuses on the complex processing of quarry tuffs-stone to extract metals (iron, titanium, copper, silver, etc.) and obtain raw materials for construction agriculture. The issue tuff-stone softening was investigated analytical dependence regularity at water saturation established, which indicates that increases with increasing mass sample according logarithmic law, dehydration proc...
