During hematogenous metastasis, the arrest of tumor cells in microvasculature is a prerequisite for extravasation from circulation to distant host organ. To reveal such behavior, we implement three-dimensional numerical simulations on motion single cell microvessels at cellular scale and mainly investigate interactions among mechanical entrapment, adhesion, stiffness, their effects arrest. Two ...

Changes in retinal geometric parameters predict risk and progression of diabetic retinopathy (DR). We have shown that vitamin D deficiency (VDD) is associated with DR. We hypothesized that VDD mediates changes in retinal geometric parameters. Retinal vascular geometric parameters were assessed using a semiautomated computer program in photographs from young people with type 1 diabetes (T1D) (n ...

Between January 1995 and December 2000, 112 children with a closed displaced supracondylar fracture of the humerus without vascular deficit, were managed by elevated, straight-arm traction for a mean of 22 days. The final outcome was assessed using clinical (flexion-extension arc, carrying angle and residual rotational deformity) and radiographic (metaphyseal-diaphyseal angle and humerocapitell...

Kidneys are the organs that remove the waste products of the metabolic activities. A smooth blood flow to the kidneys is essential to maintain their function. Abnormalities of the renal vasculature may result not only in impairing the renal function but can lead to conditions like varicocele. During an autopsy of an adult male, we observed renal vascular variations. The left renal vein had a re...

statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...

conclusion metallic stent placement is a safe and effective procedure for salvage of native hemodialysis fistula after unsuccessful balloon angioplasty. results twenty-one stents were applied. the anatomical and clinical success rate was 100%. seventeen additional interventions were done for 11 (55%) patients due to stent thrombosis or stenosis during follow-up. our 1- and 2-year secondary pate...

PURPOSE There is some indirect evidence for altered autoregulation in patients with glaucoma, but only a few studies have measured ocular blood flow directly during changes in ocular perfusion pressure. The present study was designed to compare pulsatile choroidal blood flow and optic nerve head (ONH) blood flow during moderate increases in intraocular pressure (IOP) in patients with primary op...

Objectives. To determine if hyperopia is a risk factor for primary angle-closure glaucoma (PACG) in the Dutch population and to identify other biometrical parameters as risk factors for PACG including axial length (AL), anterior chamber depth (ACD), and k values. Methods. The study population consisted of PACG patients that had undergone a laser peripheral iridotomy (LPI). The control group con...

To perform a narrow anterior chamber angle (NACA) and angle-closure glaucoma (ACG) screening using the Van Herick’s method, the width of the peripheral anterior chamber depth (PACD) and corneal thickness have to be measured. These are the key parameters to identify a patient who may be suffering from ACG. Therefore, to develop an automatic screening algorithm for NACA and ACG based on slit-lamp...

AIM Using the newly developed scanning peripheral anterior chamber depth analyser (SPAC), the effects of peripheral laser iridotomy (PLI) on peripheral anterior chamber depth (PACD) were determined quantitatively as was the association between PACD and chronic elevation of intraocular pressure (IOP) after PLI. METHODS 16 eyes of 15 patients with acute primary angle closure glaucoma (PACG) att...
