A culture vessel for maintaining cells at high density

Journal of Tissue Culture Methods, 1994
The Sykes-Moore and Rose chambers have been used for many years in time lapse studies of subconfluent cell cultures. Unfortunately, use of a Sykes-Moore chamber for the time lapse studies of cells maintained at very high cell density was found to be unsatisfactory even if a medium perfusion system was employed.

Lymphatic vessel density, microvessel density and lymphangiogenic growth factor expression in colorectal cancer

Colorectal Disease, 2007
AbstractObjective  Microvessel density (MVD) has been studied as a prognostic marker in human cancers. Quantification of lymphatic vessel density (LVD) is now possible by using new antibodies. Expression of the lymphangiogenic growth factors, VEGF‐C and VEGF‐D, is associated with poorer clinicopathological outcomes in various tumours.

Increased gingival blood vessel density in SLE patients.

Quintessence international (Berlin, Germany : 1985), 2012
Systemic lupus erythematosus (SLE) is a serious multisystem disease with a variety of cutaneous and oral manifestations. It is an autoimmune disorder whereby patients develop autoantibodies to many of their cells, cell components, and tissue. The microvascular changes in SLE play a role in the pathogenesis of this disease.

Valsalva Maneuver and Peripapillary OCT Angiography Vessel Density

Journal of Glaucoma, 2018
Purpose: To investigate the potential influence of breath holding on the results of peripapillary vessel density (VD) measurement with optical coherence tomography angiography. Materials and Methods: Three peripapillary VD measurements were made at 2-minute intervals on the right ...

Predicting the impact of retinal vessel density on retinal vessel and tissue oxygenation using a theoretical model

Mathematical Biosciences
Vascular impairments, including compromised flow regulation, have been identified as significant contributors to glaucomatous disease. Recent studies have shown glaucoma patients with significantly reduced peripapillary, macular, and optic nerve head vessel densities occurring with early glaucomatous structural changes prior to detectable visual field ...

Chemotherapy of vascularised tumours: Role of vessel density and the effect of vascular “pruning”

Journal of Theoretical Biology, 2010
In this work we propose to model chemotherapy taking into account the mutual interaction between tumour growth and the development of tumour vasculature. By adopting a simple model for this interaction, and assuming that the efficacy of a drug can be modulated by the vessel density, we study the constant continuous therapy, the periodic bolus-based ...

OCTA vessel density changes in the macular zone in glaucomatous eyes

Graefe's Archive for Clinical and Experimental Ophthalmology, 2018
To evaluate whether macular optical coherence tomography angiography (OCTA) can detect altered vessel density (VD) in the superficial and deep vascular plexus in glaucomatous eyes and to compare the diagnostic utility of the individual VD parameters.The macular VD of 135 eyes, comprising 85 eyes diagnosed with glaucoma and 50 healthy control eyes, was ...

The density and dimensions of exchange vessels in Octopus pallidus

Journal of Zoology, 1982
The microvasculature of the brachial muscle and neuropil tissues of Octopus pallidus was investigated quantitatively with the aid of electron microscopy. Morphometrically the microvascular beds of the two tissue types proved very similar. The average lumenal diameter of the exchange vessels was approximately 8·0 μm, and the average minimum vessel wall (
