Since the advent of deep brain stimulation (DBS) for the treatment of Parkinson's disease (PD), subsequent cognitive and neuropsychiatric effects of this procedure have become well-chronicled. Yet, thermolitic lesion of the subthalamic nucleus (STN) is still a valid option when DBS cannot be applied, and little has been published regarding its impact on(More)
There is an increasing number of children with traumatic and congenital hand amputations or reductions. Children's prosthetic needs are complex due to their small size, constant growth, and psychosocial development. Families’ financial resources play a crucial role in the prescription of prostheses for their children, especially when private insurance and(More)
A code ${\cal C}$ is $\Z_2\Z_4$-additive if the set of coordinates can be partitioned into two subsets $X$ and $Y$ such that the punctured code of ${\cal C}$ by deleting the coordinates outside $X$ (respectively, $Y$) is a binary linear code (respectively, a quaternary linear code). In this paper $\Z_2\Z_4$-additive codes are studied. Their corresponding(More)
The biogenesis of peptide hormone secretory granules involves a series of sorting, modification, and trafficking steps that initiate in the trans-Golgi and trans-Golgi network (TGN). To investigate their temporal order and interrelationships, we have developed a pulse-chase protocol that follows the synthesis and packaging of a sulfated hormone,(More)
PURPOSE To evaluate whether veterans with posttraumatic stress disorder (PTSD) or depression have differences in dry eye symptoms and signs compared to a population without these conditions. METHODS Male patients aged ≥50 years with normal eyelid, conjunctival, and corneal anatomy were recruited from the Miami Veterans Affairs Eye Clinic (N = 248). We(More)
PURPOSE Poor vision may detrimentally impact functional status and affect allostatic load (AL), a measure of cumulative physiological wear and tear on the body's regulatory systems. We examined the direct effects of visual acuity (VA) on mortality and its indirect effect on mortality through its impact on functional status and AL in older adults. METHODS(More)
OBJECTIVE To estimate the prevalence of, and factors associated with, dilated eye examination guideline compliance among patients with diabetes mellitus (DM), but without diabetic retinopathy. RESEARCH DESIGN AND METHODS Utilizing the computerized billing records database, we identified patients with International Classification of Diseases (ICD)-9(More)
Some kinetic properties of the microsomal cholesterol ester hydrolase (CEH) have been examined in rat liver. The reaction was linear with time up to 60 min and with enzyme concentration up to 0.3 mg/mL, and a pH optimum of 6.7 for enzyme activity was observed. Cholesterol esterase exhibited the following apparent kinetic constants: Km, 68.88 microM and(More)
