BACKGROUND The purpose of the present study was to evaluate safety and efficiency of the semi-sterile technique used in recent years in treatment of pediatric supracondylar humeral fractures (SHF). METHODS Total of 712 patients who were treated for SHF via closed reduction and percutaneous fixation with semi-sterile technique were enrolled in present study. Patients were evaluated for postope...

PURPOSE Fracture of orthodontic mini-implants during insertion is a limiting factor for their clinical success. The purpose of this study was to determine the fracture potential of commonly used self-drilling orthodontic mini-implants when placed into simulated thick, dense mandibular bone. MATERIALS AND METHODS Six mini-implant systems were assessed for the potential for fracture (Aarhus, Me...

Regnase-1 is an RNase that directly cleaves mRNAs of inflammatory genes such as IL-6 and IL-12p40, and negatively regulates cellular inflammatory responses. Here, we report the structures of four domains of Regnase-1 from Mus musculus-the N-terminal domain (NTD), PilT N-terminus like (PIN) domain, zinc finger (ZF) domain and C-terminal domain (CTD). The PIN domain harbors the RNase catalytic ce...

Coating is one of the innovative approaches used to improve the wear resistance and load-carrying capacity of surfaces in rolling-sliding contact, such as gears and rolling element bearings. In this study, the tribological performance of standard gear material (EN 16MnCr5) and two kinds of powder metallurgy (PM) gear material (Distaloy AQ + 0.2% C and Astaloy 85Mo +0.2% C) with and without trib...

Aluminum is a material that soft, lightweight, resistant to corrosion, and has good electrical thermal conductivity. specific gravity of about 2.65-2.8 kg/dm³, melting point 658ºC, tensile strength 90 MPa. 1100 series an aluminum alloy mixed with other materials, such as copper, iron, chrome, manganese, zinc, content 99,0%. Welding the joining two metals in liquid state or without filler. FSW (...

Several vulnerabilities have been found in the EMV system (also known as Chip and PIN). Saar Drimer and Steven Murdoch have successfully implemented a relay attack against EMV using a fake terminal. Recently the same authors have found a method to successfully complete PIN transactions without actually entering the correct PIN. The press has published this vulnerability but they reported such s...

OBJECTIVE To assess the magnitude and causes of over-diagnosis of prostatic intraepithelial neoplasia (PIN), as large differences are reported in the incidence of high-grade PIN, probably because of the variance in diagnosis and interpretation. PATIENTS AND METHODS Two urological pathologists prospectively reviewed 251 consecutive patients, received in consultation and who were diagnosed and ...

Plant development displays an exceptional plasticity and adaptability that involves the dynamic, asymmetric distribution of the phytohormone auxin. Polar auxin flow, which requires polarly localized transport facilitators of the PIN family, largely contributes to the establishment and maintenance of the auxin gradients. Functionally overlapping action of PIN proteins mediates multiple developme...
