Vascularity in Red and White Muscle
The voluntary muscles of many animals, including birds, cats, and rabbits, can be clearly divided into two types, (a) red or dark, and (b) white or pale. In the first half of the Eighteenth' century it was generally assumed that the red color found in some muscles was brought about by increased …

Anatomy, Histological Features, Innervation and Vascularity of the Glenoid Labrum
<b>Background</b>: The glenohumeral joint is the articulation between the head of the humerus and the glenoid fossa of the scapula, the latter being deepened and extended by the triangular fibrocartilaginous glenoid labrum attached peripherally to the margin of the glenoid fossa. The glenoid labrum …

PET-MR Imaging of Hypoxia and Vascularity in Breast Cancer
… between imaging biomarkers of tumour vascularity measured by dynamic contrast-enhanced (DCE) MRI, cellularity using diffusion-weighted imaging (DWI) and hypoxic status using 18F-fluoromisonidazole (18F-FMISO) PET. Correlations between functional PET-MRI parameters and …

Anatomical, biomechanical and histological evaluation of the glenoid labrum
… explore the (1) composition and attachment, (2) vascularity, and (3) innervation of the glenoid labrum. Labral degenerative changes were also assessed relative to the changes in labral neurovascularity that were observed. Sixteen cadaveric shoulders were obtained under the supervision of a …

UNDERSTANDING ANATOMICAL PERFUSION AND STRATEGIES TO OPTIMIZE VASCULARITY IN FREE TISSUE TRANSFER FOR AUTOLOGOUS BREAST RECONSTRUCTION USING THE DEEP INFERIOR EPIGASTRIC ARTERY PERFORATOR (DIEP) FLAP
… reconstruction and strategies to augment flap vascularity. For the ex-vivo anatomical studies, three and four-dimensional computed tomographic angiography (CTA) were used to evaluate patterns of the microvascular blood supply of individual perforators and corresponding perfusion patterns in the …

A comparison of the accuracy of various methods of postnatal gestational age estimation; including Ballard score, foot length, vascularity of the anterior lens, last menstrual period and also a clinician's non-structured assessment
… measurements (including foot-length), vascularity of the anterior lens, the New Ballard Score and Last Menstrual Period. Clinicians' non-structured global impression “End of Bed” Assessment was also evaluated. Results 106 babies were included in the study. Median age at birth was 34 …

Imaging Based Prediction of Pathology In Adult Diffuse Glioma With Applications to Therapy and Prognosis
… tumor grade, proliferation, cellularity, and vascularity, representing tumor aggressiveness. We then made voxel-wise predictions to map the tumor heterogeneity and identify high-grade malignancy disease.</p> <p>Next, we used the previously trained models on a cohort of 1,850 glioma patients …

Peptide inhibitors of angiogenesis in endometriosis and the female reproductive system
… vitro. Mice treated with ABT-898 showed reduced vascularity of endometriosis lesions compared with control. Angiogenesis is also an essential process in the female reproductive system. Females with endometriosis are of reproductive age, so it is essential to establish that anti-angiogenic …

THE EFFECTS OF BONE GRAFTING ON CALVARIAL HEALING IN A RAT MODEL
… grafts; and 2) compare effects o f bone graft vascularity on calvarial healing. Thirty-six rats were divided into Control and Experimental (EXP) groups. Parietal defects were left empty on one side. Contralateral defects in Control, EXP1, and EXP2 were partially filled with native parietal bone …

The Extraction of Type II Collagen and the Electrospinning of Nano-Fibrous Scaffolds
… to naturally regenerate due to the absence of vascularity and the inability of the chondrocytes to proliferate at a high rate. It would be ideal to create a mimicking extracellular matrix/scaffold from type II collagen that could possibly be used to replace damaged articular cartilage that has …

Development of Collateral Circulation in Partially Devascularized Feline Sciatic Nerve
… literature in the field of peripheral nerve vascularity has established that nerve function is influenced by vascular supply; however, opinion varies considerably concerning the extent of such dependence. Apparently, influence of vascular supply is unquestioned; its importance is suspected, …

Characterising fat tissue structure and function in response to hypoxia in grey seals, an animal model of extreme fat deposition and mobilisation, using novel <i>in vivo</i> and <i>in vitro</i> approaches
… evidence suggest hypoxia, as result of limited vascularity or impaired diffusion, is the underlying trigger. How seals avoid the potential detrimental effects of large, fluctuating adiposity is unknown.</p><p class="MsoNormal" style="line-height: normal; background-image: initial; …

Examining physiological roles of adipose derived VEGF: Consequences in substrate availability and endurance exercise capacity in adipocyte specific VEGF deficient mice
… factor (VEGF) in adipose tissue alters adipose vascularity and metabolic homeostasis. We hypothesized that this would also affect metabolic responses during exercise-induced stress, and that adipocyte-specific VEGF deficient (adipoVEGF-/-) mice would have impaired endurance capacity. Endurance …

The Vascular Characteristics
… CONCLUSION: These data suggest that increased vascularity is one of the major findings in melasma and VEGF may be a major angiogenic factor for altered vessels in melasma. The relationship between vessel proliferation and melanogenesis needs further research.

Factors Affecting Focal Cerebral Ischemic Infarction: Inferences from Experimental Modelling in Macaques and Murines
… as: injury size, cerebral metabolism, cerebral vascularity and perfusion, and thresholds of cell death. These confounding variables, and various animal models of stroke, are discussed in the background of the thesis. As such, the internal validity of animal models, and the external validity of …

The use of ultrasound in the prediction of endometrial cancer in women with postmenopausal bleeding
… included the variables endometrial thickness, Vascularity index (reflecting the vascularization of the endometrium when using power Doppler ultrasound), age, and use of hormone replacement therapy. The endometrial volume as measured by three-dimensional (3D) ultrasound was larger and the 3D …

The Influence of Human Umbilical Vein Endothelial Cells in the Formation of Glioblastoma Spheroids in Three-Dimensional Microwells
… with a high infiltrative capacity and increased vascularity. Despite current therapies overall patient survival rate is still poor. Therefore, alternative therapies have been considered for GBM treatment such as oncolytic viruses (OVs). The studies with two-dimensional (2D) cell cultures have …
