Postnatally derived cultures of ventral mesencephalic neurons offer several crucial advantages over embryonic ventral mesencephalic cultures, including a higher content of TH-positive cells and the ability to derive cells from the substantia nigra, which contains the neurons most vulnerable to Parkinson's disease. On the other hand, these cultures are more challenging to produce consistently. H...

The role of ventricular ectopic beats (VEBs) in identifying patients who die of cardiac cause in the posthospital phase of myocardial infarction was evaluated in 940 patients who survived an acute coronary event. Six-hour Holter ECG recordings were obtained before hospital discharge, and VEBs were classified as complex (bigeminal, multiform, repetitive or R on T), simple (one or more VEBs that ...

Solitary rectal ulcer syndrome (SRUS) is a chronic, multiform, non-cancerous disorder of the rectum, the final diagnosis of which is based upon histopathological criteria. This disorder is often accompanied by latent proctoptosis. We present a patient who (in 1996) was the first case in which argon plasma coagulation (APC) was used for SRUS treatment. In the years 2004-2005 the same patient und...

We provide conceptual introductions to missingness mechanisms--missing completely at random, missing at random, and missing not at random--and state-of-the-art methods of handling missing data--full-information maximum likelihood and multiple imputation--followed by a discussion of planned missing designs: Multiform questionnaire protocols, 2-method measurement models, and wave-missing longitud...

A Mn(II) metal-organic framework {[MnL2(NCS)2]·(H2O)4}n (1) with L = bis(pyridin-3-ylmethylene)biphenyl-2,2′-dicarbohydrazide has been synthesized and characterized by IR spectroscopy, elemental analysis, UV spectroscopy, thermogravimetric (TG) analysis, powder X-ray diffraction, and single-crystal X-ray structure determination. The Mn(II) atom has a distorted octahedral coordination environmen...

Digital Libraries continue to evolve towards research environments supporting access and management of multiform Information Objects spread across multiple data sources and organizational domains. This evolution has introduced the need to deal with Information Objects having traits different from those characterizing Digital Libraries at their early stages and to revise the services supporting ...

The perirhinal cortex in the dog's brain is composed of two traditional Brodmann's areas: 35 and 36. Area 35 is situated along the entire rostro-caudal extent of the fundus of the posterior rhinal sulcus, whereas area 36 occupies its lateral bank. In this study, four subdivisions were distinguished in area 35 based on cytoarchitectonic differentiation. Area 36 is poorly developed in the dog's b...

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by infiltration of the myocardium by adipose and fibrous tissue. The disease is an important cause of sudden death in humans, but has rarely been described in animals. This report describes ARVC in two cats with right-sided congestive heart failure. One cat had also experienced previous episodes of syncope. Standa...

Social welfare is one of the accepted goals of the United States and of the entire free world. Great interest attaches, therefore, both in this country and elsewhere, to the status of social wegare programs in the United States today. The standard of living and general welfare of the American people derive from the multiform activities of a free people, working individually, through voluntary g...
