Elastography is based on the estimation of strain due to tissue compression or expansion. Conventional elastography involves computing strain as the gradient of the displacement (time-delay) estimates between gated pre- and postcompression signals. Uniform temporal stretching of the postcompression signals has been used to reduce the echo-signal decorrelation noise. However, a uniform stretch of the entire postcompression signal is not optimal in the presence of strain contrast in the tissue and could result in loss of contrast in the elastogram. This has prompted the use of local adaptive str

Background. Crush syndrome is manifested by the activation of the pituitary-hypothalamic-adrenal system, what is confirmed by a significant increase in the blood levels of catecholamines, cortisol and corticosterone. Its antagonist is the atrial natriuretic peptide, which is synthesized by the myoendocrine cells of the heart, but the question of its participation in the implementation of the adaptation syndrome under the conditions of the postcompression period of crush syndrome remains unresolved.

High-efficiency, high-quality biomedical image compression is desirable especially for the telemedicine applications. This paper presents an adaptive coding pass scanning (ACPS) algorithm for optimal rate control. It can identify the significant portions of an image and discard insignificant ones as early as possible. As a result, waste of computational power and memory space can be avoided. We replace the benchmark algorithm known as postcompression rate distortion (PCRD) by ACPS. Experimental results show that ACPS is preferable to PCRD in terms of the rate distortion curve and computation t

To determine the acute effects of increased pulmonary artery pressure and flow on the fetal pulmonary circulation, we studied the response of pulmonary blood flow and vascular reactivity to partial compression of the ductus arteriosus in 22 chronically prepared late-gestation fetal lambs. An inflatable occluder was placed loosely around the ductus arteriosus for compression. Partial compression of the ductus rapidly increased mean pulmonary artery pressure from 45 +/- 1 to 60 +/- 1 mmHg (mean +/- SE) and left pulmonary artery blood flow from 65 +/- 6 to 151 +/- 11 ml/min at 30 min (P less than

Elastography is a method for imaging the elastic properties of compliant tissues which produces gray scale elasticity images called elastograms. The elastograms of phantoms with homogeneous elastic properties exhibit a noisy appearance. We demonstrate that this noisy appearance of the elastograms is due to the nonstationary relationship between the pre- and postcompression signals that results in an artifactual modulation of the strain estimates by the amplitude variations of the envelope of the rf signal. We have identified two methods to reduce the strain modulation artifact. The first metho

Poroelastography has been recently introduced as a new elastographic technique that may be used to describe the spatial and temporal behavior of poroelastic materials. The experimental methodology proposed thus far for phantoms and tissues in vitro requires the acquisition of a precompression rf frame, the application of a unit step strain compression to the sample and the acquisition of subsequent post-compression frames from the material. Elastograms and poroelastograms are generated by cross-correlating the sequentially-acquired postcompression frames with the reference precompression frame

Ebastine is a long-acting, nonsedating, second-generation antihistaminic drug that prevents histamine action, mainly in immediate hypersensitivity. This project was aimed to formulate and characterize orodispersible tablets of ebastine, utilizing different proportions of three disintegrants, namely crospovidone, sodium starch glycolate, and coprocessed superdisintegrant. Initially, fifteen trial batches of ebastine orodispersible tablets were outlined using the central composite design of Minitab software. The tablets were formulated by the direct compression method.

This study aims to improve the biopharmaceutical, mechanical, and tableting properties of a poorly soluble drug, ibuprofen (IBP), by preparing amorphous solid dispersion (ASD) followed by a sustained-release tablet formulation. A suitable polymer to develop an ASD system was chosen by utilizing the apparent solubility of IBP in various polymer solutions. ASDs containing various ratios of IBP and selected polymer were prepared by the melt fusion (MF) method. ASD containing optimized drug-polymer ratio prepared by freeze-drying (FD) method was characterized and compared physicochemically. The so

ABSTRACT Context: Chronotherapeutic delivery of antihypertensives plays a potential role in the treatment by providing a therapeutic amount of drug at the target site in the body. Sacubitril–valsartan (SV), an angiotensin receptor neprilysin inhibitor, has been indicated for the treatment of hypertension. The study explores the formulation and evaluation of compression-coated tablets (CCTs) of SV using a natural super disintegrant in the core tablet for chronotherapeutic drug delivery.
