Parametric And Non-parametric Analysis Of Carotid Sinus Baroreflex System Using Electrically Induced Muscle Contraction
(Biomedical Engineering, 2007-08-23)
The arterial pressure is an important physiological parameter which if not maintained at desired level may lead to fatal disorders or in worst situations even death. The physiological feedback control mechanism in order ...
Flow Rate Measurement Of In Situ Perfusion Through The Aqueous Humor Outflow Network
(Biomedical Engineering, 2007-08-23)
A system was developed to measure the instantaneous perfusate flow rate through the aqueous humor outflow network of a human eye, while under constant pressure. The system monitors real-time weight changes of a perfusate ...
A Novel Approach In The Detection Of Obstructive Sleep Apnea From Electrocardiogram Signals Using Neural Network Classification Of Textural Features Extracted From Time-frequency Plots
(Biomedical Engineering, 2007-08-23)
Sleep-Disordered Breathing (SDB) is estimated to have a prevalence of 5% in middle-aged population. The population is widely thought to be under diagnosed, since the present method to detect and diagnose SDB, Nocturnal ...
Optimization Of Methods For In-vitro Expansion And Cryopreservation Of Mammalian Stem Cells
(Biomedical Engineering, 2007-08-23)
The recent advances in the field of Tissue Engineering have given rise to the need for a tremendous quantity of cells. The search for and use of an appropriate multipotent or pluripotent stem cells in tissue engineering ...
MR Susceptibility Weighted Imaging And Its Clinical Applications
(Biomedical Engineering, 2007-08-23)
Susceptibility Weighted Imaging (SWI) is a new T2* weighted Gradient Echo sequence that exploits the magnetic properties of tissues due to local inhomogeneities in the magnetic field. This technique was originally called ...
Resolution And Localization In Single Molecule Microscopy
(Biomedical Engineering, 2007-09-19)
Rayleigh's criterion is extensively used in optical microscopy to determine the resolution of microscopes. Despite its widespread use, it is well known that this criterion is based on heuristic notions and can be surpassed ...
Gas Permeation Through Nanoporous Polycarbonate Track- Etched Membranes: Pulsed Plasma Polymerization Of Thin Coatings To Modulate Gas Permeability
(Biomedical Engineering, 2007-09-17)
Polycarbonate track-etched membranes (PCTE) of 50nm and 100nm pore size, precoated with Poly Vinyl Pyrrolidone (PVP), were surface treated with either Vinyl Acetic acid (VAA) or Perfluorohexane (C6F14) using a low duty ...
Implantable Drug Delivery System With In-plane Micropump
(Biomedical Engineering, 2007-08-23)
A MEMS based Implantable Drug Delivery System (IDDS) is discussed. The heart of the system is an in-plane MEMS micropump enables us to make a compact, inexpensive system. A conceptual IDDS design is proposed. This design ...
Phenotypic Differences In The Behavior Of Immortalized Human Bronchial Epithelial Cells In Three Dimensional Culture Systems
(Biomedical Engineering, 2007-08-23)
Human Bronchial Epithelial Cells (HBECS) immortalized with viral oncoproteins E6/E7, are potentially malignant due to numerous chromosomal aberrations. Recently a model system was established in which HBECS were immortalized ...
Tissue And Vascular Oxygenation Dynamics Determined By Optical Approaches And MRI
(Biomedical Engineering, 2007-09-17)
Tumor oxygenation is a crucial factor to determine the efficiency of non-surgery therapy, such as radiotherapy and chemotherapy. Therefore, various approaches have been applied to tumor in order to improve the tumor oxygen ...
