Did the UN convention on the rights of the child reduce child mortality around the world? An interrupted time series analysis.

Background: Child mortality has been reduced by more than 50 % over the past 30 years. A range of secular economic and social developments have been considered to explain this phenomenon. In this paper, we examine the association between ratification of the Convention on the Rights of the Child (CRC), which was specifically put in place to ensure the well-being of children, and declines in child mortality.

Rotational Pedicle Myocutaneous Forearm Fillet Flap Used to Fill Forequarter Amputation Defect: Indications and Uses.

A full-thickness fourth-degree burn to a large area of the upper extremity may require a forequarter amputation. Whereas our case describes a burn injury, forequarter amputations may more commonly be done in oncological surgery. In addition to the challenge of providing well-vascularized tissue coverage, the burn patient may also pose the complication of respiratory compromise in a systemically ill person.

Chapter 3. The adenoviral vector angiogenesis/lymphangiogenesis assay.

Adenoviral vectors expressing vascular permeability factor/vascular endothelial growth factor (VPF/VEGF, VEGF-A(164)) offer a powerful method for elucidating the mechanisms of pathological angiogenesis and lymphangiogenesis and for evaluating the effectiveness of pro- and anti-angiogenesis therapies. When injected into any of a variety of tissues in nude mice or rats, adenoviral vectors expressing VEGF-A(164) (Ad-VEGF-A(164)) induce the formation of six structurally and functionally distinct types of new blood vessels: mother vessels (MV), capillaries, glomeruloid microvascular proliferations (GMP), vascular malformations (VM), feeding arteries (FA), and draining veins (DV). Each of these abnormal vessel types may be found in tumors and in other examples of pathological angiogenesis.

Permeability properties of tumor surrogate blood vessels induced by VEGF-A.

Malignant tumors generate new blood vessels by secreting growth factors, particularly members of the vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) family. Overall, the new blood vessels that form are hyperpermeable to plasma proteins, a property that is thought to be important for generating new stroma. However, tumor blood vessels are structurally heterogeneous and include microvessels of at least the following distinct types: mother vessels (MV), glomeruloid microvascular proliferations (GMP), arterio-venous-like vascular malformations and capillaries.

Identification of viral genes essential for replication of murine gamma-herpesvirus 68 using signature-tagged mutagenesis.

Gamma-herpesviruses, Epstein-Barr virus, and Kaposi's sarcoma-associated herpesvirus are important human pathogens, because they are involved in tumor development. Murine gamma-herpesvirus-68 (MHV-68 or gammaHV-68) has emerged as a small animal model system for the study of gamma-herpesvirus pathogenesis and host-virus interactions. To identify the genes required for viral replication in vitro and in vivo, we generated 1,152 mutants using signature-tagged transposon mutagenesis on an infectious bacterial artificial chromosome of MHV-68.
