The lipolytic processing of triglyceride-rich lipoproteins by lipoprotein lipase (LPL) is the central event in plasma lipid metabolism, providing lipids for storage in adipose tissue and fuel for vital organs such as the heart. LPL is synthesized and secreted by myocytes and adipocytes, but then finds its way into the lumen of capillaries, where it hydrolyzes lipoprotein triglycerides. The mech...

By means of injections made into the coronary arteries of beating hearts it has been possible to determine the number of capillaries in the normal heart muscle. This study has shown a very rich blood supply with an average of approximately one capillary for each muscle fibre in the ventricular walls and papillary muscles, and a less abundant supply in the auricular muscle and Purkinje system. T...

Introduction: Nailfold capillaroscopy is a simple, non-invasive technique used to assess microcirculation in various diseases such as Systemic Sclerosis, Dermatomyositis, Diabetes Mellitus, and Hypertension etc. Microcirculation is the part of the circulation where oxygen, nutrients, hormones, and waste products are exchanged between circulating blood and parenchyma cells through the blood vess...

The purpose of this investigation was to study the fine structure of pulpal capillaries located in the odontoblastic layer and immediate subjacent zone. The observations were from first molars of white mice sacrificed at five day intervals from 25-90 days. Both capillaries and small vessels with an incomplete smooth muscular coating appeared in the zone subjacent to the odontoblastic layer from...

A theory of contact angle hysteresis of a meniscus inside thin capillaries with smooth, homogeneous solid walls is developed in terms of surface forces (disjoining/conjoining pressure isotherm) using a quasi-equilibrium approach. The disjoining/conjoining pressure isotherm includes electrostatic, intermolecular, and structural components. The values of the static receding θr, advancing θa, and ...

Brain microvasculature plays a critical role in the regulation of homeostasis of neural tissues. The present study focuses on characteristic microvascular basement membrane (bm) aberrations in the midbrain periaqueductal gray matter (PAG) and their relation to aging. The PAG can be considered a caudal extension of the limbic system and is a key structure in the regulation of a myriad of autonom...

LARGELY owing to technical difficulties the role of the capillary in human disease is not known. Chambers (1948) stated that an adequate survey of the capillary bed for study of the variations in its functional activity required tissue in which the vessels could be traced from the arteriolar to the venular ends, and at the same time be exposed for observation with a minimum of trauma so as not ...

Terminal extensions of subodontoblastic capillaries have been observed histologically among odontoblasts in coronal pulp in a variety of species, including man. James (J Anat 89:54749, 1955), Adams (I Dent Res 38:968-78, 1959), Klingsberg et al (J Dent Res 38:419, 1959), Adams (Arch Oral Biol 7:773-774, 1962), and Jesson (Atda Odontol Scand 25: 491-523, 1967) observed capillaries at varying dep...

Adsorbed proteins on walls of glass capillaries used for electrospray (ES) can desorb and potentially affect size distributions and, thus, quantification of aggregates of proteins. In this study we use differential mobility analysis (DMA) to investigate the size distribution of various proteins eluting from bare and passivated glass capillaries. We found no significant differences in aggregate ...

Electrocardiographic tracings were performed on 26 strain 2 guinea pigs in which leukemia was induced by inoculation of L2C leukemic cells. All inoculated animals developed leukemia. In terminal phases of this disease significant electrocardiographic changes were observed in 20 of the 26 animals; in 5 animals the electrocardiograms were normal and in 1 guinea pig the changes were borderline. Th...
