After partial lesions, uninjured nerve fibers have been shown to sprout and expand their connections within the CNS of adult mammals. The extent of this anatomical plasticity in adults is rather limited in comparison to embryonic or neonatal animals. Factors that might limit sprouting of nerve fibers and suppress anatomical plasticity in the CNS include myelin-associated neurite growth inhibito...

Pertussis is a vaccine-preventable disease that affects people of all ages. Young adults who have lost their immunity to pertussis are the major source of infection in infants. Given the steady increase of pertussis cases, new prevention strategies are required. Objective. To assess pertussis seroprevalence in adult blood donors, post-partum women, and umbilical cords. Metod. Measurement of tot...

In this paper a purely algebraic condition for a word in a free group to be representable by a simple curve on a punctured plane will be given. As an application, an algorithm for simple closed curves on a punctured plane will be obtained. Our solution is different from any algorithm due to Reinhart [12], Zieschang [13] or Chillingworth[2]. Although the study here will be confined to the case o...

BACKGROUND Elastic cords hitting the eyeball as high-speed projectiles can severely damage ocular structures and can produce permanent visual function impairment. OBJECTIVES To evaluate the frequency, mechanics, and severity of eye injuries caused by elastic cords in children to adopt the most appropriate preventive measures. METHODS A retrospective medical records review of hospital admiss...

Testes from 11.5-day-old mouse embryos, with and without attached mesonephroi, were cultured for 7 days. Isolated testes failed to develop well-differentiated testis cords: however, when cultured attached to a mesonephros from either a male or a female donor embryo, testes developed cords that were normal in appearance. Testes cultured next to a mesonephric region but separated from it by a per...

OBJECTIVES The aim of this study is to assess preserved umbilical cords as chemical exposure media to investigatein utero chemical exposure. Furthermore, we aim to apply preserved umbilical cords to retrospective studies of the relationship betweenin utero chemical exposure and neurodevelopment disorders. METHODS Two sets of preserved umbilical cord samples were analyzed for exposure to polyc...

We are presenting a case of a 26 year old healthy male, who came with gradual worsening of dyspnoea following prolonged intubation and ventilation, after a road traffic accident five months back. On arrival in ER, he was hypoxaemic with severe respiratory distress. He was transferred to the operation room (OR) for emergency tracheostomy. During the transfer, he was placed in an upright position...

This report describes an in vitro system that could be useful for investigating corneal neovascularization. When isolated bovine capillary endothelial cells (CEC) were cocultivated with rabbit corneal keratocytes, capillary-like cords extended actively from the endothelial cells in the multilayers of the keratocytes. The developing cords continued to elongate, branch out, and anastomose with ea...

Angiogenesis results in part from the response of endothelial cells to the integrated action of morphogenic factors and extracellular matrix proteins. In this study we identified specific components of the extracellular matrix that were modulated in endothelial cells derived from bovine aorta and rat cerebral microvessels, both of which spontaneously form cords and tubes under standard culture ...
