F ollowing myocardial infarction, left ventricular (LV) remodeling is characterized by increased LV end-diastolic and end-systolic volumes (ESV) and decreased LV ejection fraction (EF) (1). This process is driven by elongation of infarcted zones and changes within the unaffected myocardium, including myocyte hypertrophy and interstitial collagen deposition. With medical therapy, revascularizati...

In this paper, we study two new methods for approximating the viability kernel of a given set for a HH olderian diierential inclusion. We approximate this kernel by viability kernels for discrete dynam-ical systems. We prove a convergence result when the diierential inclusion is replaced by a sequence of recursive inclusions. Furthermore , when the given set is approached by a sequence of suita...

Cell viability may be judged by morphological changes or by changes in membrane permeability and/or physiological state inferred from the exclusion of certain dyes of the uptake and retention of others. This unit presents methods based on dye exclusion, esterase activity, and mitochondrial membrane potential, as well as protocols for determining the pre-fixation viability of fixed cells either ...

Necessary and sufficient conditions for a set-valued map K : R ։ R to be GDQ-differentiable are given. It is shown that K is GDQ differentiable at t0 if and only if it has a local multiselection that is Cellina continuously approximable and Lipschitz at t0. It is also shown that any minimal GDQ of K at (t0, y0) is a subset of the contingent derivative of K at (t0, y0), evaluated at 1. Then this...

The ultimate challenge for all in vitro fertilisation (IVF) clinics is to develop the ability to select for transfer the best single embryo first, from the patient’s cohort of embryos, thereby maximising the chance of pregnancy while the incidence of multiple pregnancies is kept to a minimum and fewer transfer cycles are required. This ambition has driven extensive research and development into...

introduction: sperm viability test is important in diagnosis and treatment of male infertility. the common test is e&n; and host which they are based on membrane permeability and integrity. the aim of this study was to evaluate mtt assay as a sperm viability test based on mitochondrial activity. materials and methods: washed sperm samples were co-incubated with mtt in different media and differ...
