Microfluidic technologies have substantially advanced cancer research by enabling the isolation of rare circulating tumor cells (CTCs) for diagnostic and prognostic purposes. The characterization of isolated CTCs has been limited due to the difficulty in recovering and growing isolated cells with high fidelity. Here, we present a strategy that uses a 3D scaffold, integrated into a microfludic d...

The present study was aimed at developing a new strategy to design and anchor custom-fitted implants, consisting of a head fixation device and a chronic recording chamber, on the skull of adult macaque monkeys. This was done without the use of dental resin or orthopedic cement, as these modes of fixation exert a detrimental effect on the bone. The implants were made of titanium or tekapeek and ...

statement of problem: perforations are significant complications that can occur during root canal therapy and may result in the destruction of adjacent periodontal tissues. an ideal material for repairing a perforation should be biocompatible and have a high sealing ability. purpose: the aim of this study was to compare histologic tissue responses of experimentally induced pulp chamber perforat...

We present a design and evaluation of simple easy-to-fabricate conductive heater intended for ultra-high vacuum experiments. demonstrate compact power-dense that has minimal outgassing up to nearly 200 °C. further detail method using the in air heat an object by partially replacing glass chamber wall with silicon, avoiding some possible issues. This successfully loaded 2D magneto-optical trap f...

Introduction: The present study aimed to present a numerical analysis of the penetration depth,  specific absorption rate (SAR), and temperature rise in various eye tissues with varying distance between radiation source and exposed human eye tissues (i.e., cornea, posterior chamber, anterior chamber, lens, sclera, vitreous humor, and iris) at frequencies of 900 and1800 MHz. Materials and Method...

Introduction: Dental turbine chamber is a suitable reservoir for living microorganisms, so chamber sterilization is necessary for reducing cross contamination risk. On the other hand, in non-vacuum autoclaves, steam penetration into turbine chamber is doubtful, while they are still in use in dental clinics. In this study, performance of small non-vacuum autoclave in turbine chamber sterilizatio...

Cardiac ultrasound, or echocardiography, is considered to be the quickest and most cost effective imaging modality for assessment of cardiac function. The modality is unique in that it allows for real-time imaging of the heart, using portable equipment. The latest generation of echocardiography scanners are capable of acquiring dense image volumes in either real time, or over a few heart beats....

Fabrication of macroscopic three-dimensional (3D) structures made nanofibers widely used polymers is reported. 3D have several benefits over conventional flat two-dimensional (2D) by the added dimension. The been fabricated electrospinning technology that can build rapidly due to certain additives in solution and appropriate process conditions. parameters identified investigated better understa...

A 65-year-old woman with severe paravalvular mitral regurgitation and chronic hemolytic anemia was referred for surgical consultation. Her medical history included rheumatic heart disease with mitral valve replacement in 1977, aortic valve replacement in 1988, and repeat mechanical mitral valve replacement in 2002. Predominant symptoms were New York Heart Association function class III dyspnea ...
