The ubiquitin-proteasome system in glioma cell cycle control
(2012)A major determinant of cell fate is regulation of cell cycle. Tight regulation of this process is lost during the course of development and progression of various tumors. The ubiquitin-proteasome system (UPS) constitutes ... -

UGT1A1 promoter polymorphism as a predisposing factor of hyperbilirubinaemia in neonates with acute pyelonephritis
(2006)We describe 4 jaundiced neonates with acute pyelonephritis of whom family history was positive for or pointed to Gilbert's syndrome (GS). Uridine diphosphate glucuronosyltransferase 1A1 (UGT-1A1), ( TA) 7 polymorphism, ... -
Ultimate bending capacity and buckling of pressurized 90 deg steel elbows
(2006)The paper examines the nonlinear elastic-plastic response of internally pressurized 90 deg pipe elbows under in-plane and out-of-plane bending. Nonlinear shell elements from a general-purpose finite element program are ... -
Ultimate capacity of pipe bends under bending and pressure
(2008)The structural capacity of pressurized pipe elbows under in-plane bending is examined. The investigation is conducted through advanced finite element analysis tools. The numerical results are successfully compared with ... -
Ultimate capacity of pressurized 90 DEG elbows under bending
(2004)In this paper the response of internally pressurized pipe elbows under bending loads (in-plane and out-of-plane) is examined. The investigation is conducted through advanced finite element analysis tools, supported by ... -
Ultimate capacity of welded-slip joints under axial compression
(2006)Using advanced numerical tools, which account for the cold-expansion manufacturing process, the axial capacity of welded slip pipeline joints under compressive loading is investigated. The numerical results are in good ... -
Ultimate compressive strength of CHS members with flattened edges
(2003)The paper studies circular hollow members which have been submitted to a procedure for the formation of a flattened edge. Two different ways of formation of flattened edges are investigated, one involving a single-step ... -
The ultimate limits of wireless networks
(2012)This paper discusses the grand challenges associated with the holy grail of understanding and reaching the ultimate performance limits of wireless networks. Specifically, the next goal in the networking community is to ... -
Ultra wideband, low-power, 3-5.6 GHz, CMOS voltage-controlled oscillator
(2009)In this paper, a low-power inductorless ultra wideband (UWB) CMOS voltage-controlled oscillator is designed in TSMC 0.18 mu m CMOS technology as a part of a ultra wideband FM (UWBFM) transmitter. The VCO includes a ... -
Ultra-early planting effects on maize crop development, yield, and weed control
(2006)Field experiments were conducted in 2001 and 2002 at the University of Thessaly Research Farm in Velestino, using three planting dates, namely: ultra-early (U-E, March 1 or 2), early (E), and normal (N) that were at least ... -
Ultra-real or symbolic visualization? the case of the city through time
(2006)The distinctive character of digital technology has created new conditions of approach and processing. The city as the object of visualization has its own peculiarities as a separate object, notwithstanding the demands ... -
Ultra-Wideband, Low-Power, Inductorless, 3.1-4.8 GHz, CMOS VCO
(2011)A low-power, inductorless, UWB CMOS voltage controlled oscillator is designed in 0.18 mu m CMOS technology targeting to a UWBFM transmitter application. The VCO is a Double-Cross-Coupled Multivibrator and generates output ... -
Ultrasonic monitoring of bone fracture healing
(2008)Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an ... -
Ultrasonographic appearance of clinically healthy testicles and epididymides of rams
(2003)The clinically healthy testicles and epididymides of 31 rams were imaged inside and outside the breeding period, by using a real time ultrasound scanner. A scanning technique based on multiple imaging planes from the caudal ... -
Ultrasonographic evidence of inflammation is frequent in hands of patients with erosive osteoarthritis
(2009)Objective: Erosive osteoarthritis (OA) (EOA) is considered an aggressive form of primary OA that is defined radiographically by intra-articular erosions of the inter-phalangeal joints of the hand and characteristic ... -
Ultrasonographic findings in the ovine udder during involution
(2014)The objective of the study was to record, by means of ultrasonographic examination, changes occurring in the udder of ewes during involution and to compare differences between progressive or abrupt udder drying-off. In ... -
Ultrasonographic findings in the ovine udder during lactogenesis in healthy ewes or ewes with pregnancy toxaemia
(2015)Objective of the study was to record, by means of ultrasonographic examination, changes occurring during lactogenesis in the udder of healthy ewes and of ewes with pregnancy toxaemia. The work was carried out in 28 ewes, ... -
Ultrasonography in differentiation between chronic viral hepatitis and compensated early stage cirrhosis
(2008)AIM: To assess the value of gray scale (GS) and colour Doppler ultrasonography (CDU) in differentiating the progression of chronic viral hepatitis (CVH) and compensated liver cirrhosis (CIR). METHODS: Seventy-two patients ...
