Increasing life expectancy has led to a rise in hip fractures and an associated increase hemiarthroplasty procedures aimed at restoring mobility preventing muscle loss. Despite the extensive literature on failed hemiarthroplasty, limited data address influence of pre-operative fracture types—intracapsular versus extracapsular—on outcomes, including inpatient mortality. This study investigates revisions uncemented bipolar hemiarthroplasties concerning type identifies risk factors for...

Abstract BACKGROUND: Specific energy consumption (SEC) is an important factor in electrochemical treatment of wastewaters. SEC during food industry wastewaters, specifically deproteinated whey wastewater (DWW), simulated sugar beet factory (SFW) and fruit juice (FJW), were investigated this study. The effects operational parameters applied voltage, electrolyte concentrations on assessed optimized. RESULTS: values found the range 0.27–148.65, 0.94–375.76 0.20–636.40 kWh (kg COD) −1 for DWW,...

In this work, a new random number generator circuit using continuous-time chaos is described. The based on the classical dual oscillator sampling technique. approaches, jittered oscillations used in technique are obtained physical noise. we propose to use generate these oscillations. required chaotic signal from jerk which can very easily be realized. proposed realized laboratory with discrete components and bit sequence generated circuit. level of randomness tested by NIST-800-22. results...

Background The most important cause of patient dissatisfaction following total knee arthroplasty (TKA) is pain. Component rotation an factor in the clinical success TKA. This study aims to determine component rotational errors patients with mobile- and fixed-bearing polyethylene inserts after TKA also evaluate effect possible malrotations on outcomes. Methods Seventy-five knees from sixty-six who underwent were evaluated retrospectively. divided into two groups according whether they...

Abstract Modifying genes play an exclusive role in the genetic regulation of risk breast cancer development women with a pathogenic variation BRCA1 or BRCA2 . Therefore, it has been suggested that TNFRSF11A , which is among those modifying present development, may have significant patients positive variations. In our study, we investigated probable effects single nucleotide polymorphisms (SNPs) gene, such as rs4485469, rs9646629, rs34739845, rs17069904, rs 884205, rs4941129 on A total 23...

The patients characterized with chronic subclinical inflammation even during attack-free periods, are now considered to have an increased risk of atherosclerotic complications as well other autoinflammatory disease. Damage the arterial wall due atherosclerosis causes stiffness. Pulse wave velocity (PWV), a noninvasive measure stiffness, is accepted be indicator atherosclerosis. Cardiovascular disease included various markers; blood biomarkers and genetic markers. Matrix metalloproteinases...
