CXCR4, stromal cell-derived factor-1α(SDF 1α) receptor, stimulates growth and metastasis of hepatocellular carcinoma (HCC). Alpha-fetoprotein(AFP) governs the expression of some metastasis-related genes. Here we report that AFP and CXCR4 levels correlated in HCC tissues. AFP-expressing vectors induced CXCR4. In agreement, AFP depletion by siRNA decreased CXCR4. AFP co-localized and interacted with PTEN, thus inducing CXCR4 by activating AKT(Ser473) phosphorylation. In turn, phospho-mTOR(Ser2448) entered the nucleus and bound the CXCR4 gene promoter...

INTRODUCTION: Postoperative urinary retention requiring urethral catheterisation increases the risk of joint sepsis following arthroplasty. Spinal anaesthesia with opiate administration is used widely in lower limb arthroplasty. We sought to establish whether the choice of opiate agent had any effect on the incidence of postoperative retention and therefore the risk of joint sepsis. METHODS: A total of 445 consecutive patients who underwent primary elective lower limb arthroplasty were reviewed retrospectively...

PURPOSE OF THE STUDY: Surgical incision closure, as well as total joint replacement itself, plays a key role in the overall outcome of an arthroplasty procedure. Uncomplicated wound healing is the essential condition of successful rehabilitation and the patient's return to normal activities. Although there are many innovative suturing techniques which offer advantages, their safety is still being discussed. The aim of this prospective non-blind randomised study was to evaluate wound healing and complications in relation to skin incision closure with either conventional suture or metal staples...

Using data from a daily diary study of hourly hotel employees in the U.S. and their children, this study examined links between youth supervision arrangements and maternal worry while at work, examining both differences between individuals and day-to-day variation within individuals. Multilevel model analyses revealed both between- and within-person effects linking youth supervision to maternal worry. Mothers' partner status functioned as moderator, and maternal knowledge also emerged as a protective factor when youth were in self-care, highlighting a potential target for future work-family interventions, particularly those for hourly employees with limited access to family-friendly workplace policies...

Abstract Elderly patients with acute myeloid leukemia (AML) have a poor prognosis. The authors examined the in vitro and clinical activity of the histone deacetylase inhibitor valproic acid (VA) combined with cytosine arabinoside (AraC) in elderly patients with AML unsuited to intensive therapy. For the in vitro studies, primary AML cells from 11 patients were treated with AraC and VA and analyzed for apoptosis, cytostatic effects, differentiation and acetyl histone H3 induction. VA (alone and with AraC) enhanced apoptosis and induced acetyl histone H3...

AIMS: To audit all patients admitted to a New Zealand (NZ) Hospital with an acute coronary syndrome (ACS) over a 14-day period, to assess their number, presentation type and patient management during the hospital admission and at discharge. To compare patient management in 2007 with the 1st NZ Cardiac Society ACS Audit from 2002. METHODS: We updated the established NZ ACS Audit group of 36 hospitals to 39 hospitals now admitting ACS patients across New Zealand. A comprehensive data form was used to record individual patient information for all patients admitted between 00...

We study the impact of wall corrugations in microchannels on the process of capillary filling by means of three broadly used methods: computational fluid dynamics (CFD), lattice Boltzmann equations (LBE), and molecular dynamics (MD). The numerical results of these approaches are compared and tested against the Concus-Finn (CF) criterion, which predicts pinning of the contact line at rectangular ridges perpendicular to flow for contact angles of theta > 45 degrees . Whereas for theta = 30, 40 (no flow), and 60 degrees (flow) all methods are found to produce data consistent with the CF criterion, at theta = 50 degrees the numerical experiments provide different results...

Spontaneous capillary flow (SCF) of a drop in a groove with an ideally sharp corner is possible when the Concus-Fin (CF) condition is fulfilled. However, since ideally sharp corners do not exist in reality, it is important to understand the effect of finite corner curvature on SCF. This effect is analytically studied for long drops in a V-shaped groove with a curved corner, leading to a generalization of the CF condition for such drops. The generalized condition implies that SCF depends on the geometry of the corner as well as on the dimensionless length of the drop, in addition to its dependence on the opening angle and contact angle that is covered by the CF condition...

Estimates above and below are obtained for the height of the equilibrium-free surface of a liquid when the liquid partially fills a cylindrical container whose cross section contains a corner with interior angle 2alpha. The surface is characterized by the condition that its mean curvature be proportional to its height above a reference plane (or, in the case of zero gravity, that the mean curvature be constant), and by the requirement that it meet the container wall with prescribed contact angle gamma. It turns out that the qualitative behavior of such a surface near the vertex changes markedly, according as alpha + gamma < (1/2)pi, or alpha + gamma >/= (1/2)pi...

OBJECTIVES: Radiosurgery precisely delivers a single high dose or a few fractionated doses of radiation to a localized tumor via the stereotactic approach. Some head and neck sites are suitable for radiosurgery since there is minimal or no organ motion. The clinical studies were carried out to determine the accuracy of stereotactic radiosurgery and to demonstrate the effectiveness of radiosurgery in head and neck cancers. MATERIALS AND METHODS: Thirteen patients were treated with either single-dose or fractionated radiosurgery to the tumor...

OBJECTIVE: To identify altered gene targets that characterize disease progression in squamous cell carcinoma (SCC) of the head and neck (HNSCC). Genetic alterations in HNSCC cell lines reflect the tumor in vivo and can serve as valuable tools to study the development and progression of HNSCC. Identification of key molecular events may be useful for more accurate distinction of prognostic groups for selection and targeting of therapy. DESIGN: Individual gene loci were analyzed for genetic alterations using a novel genomewide strategy...

Postirradiation sarcomas of the head and neck are rare. When they do occur, most appear at least 10 years following radiation therapy. We report three cases of early-onset (1, 2, and 7 yr) postirradiation sarcoma. Physicians who care for previously irradiated patients should consider the possibility of a postirradiation sarcoma whenever they see a suspicious lesion, regardless of the amount of time that has passed since radiation therapy was administered. The original pathology should be reexamined to ensure that the original tumor was diagnosed correctly...
