The population-ecology approach (the natural-selection model) used to be a major orientation in consideration of organizational change and transformation. It is presented by its proponents as a theory distinct from structural contingency theory. This theory begins by rejecting the claim of contingency theory that organizations are adaptive. Contingency theory understands that the social and bus...

The primary education sector in Pakistan faces many challenges relating to access to education and quality of resources. This paper evaluates the Educational Voucher Scheme (EVS) in Lahore, Pakistan aimed at increasing access to primary schooling for low income families residing in the underdeveloped areas of Lahore by using the four criteria for evaluating privatization plans in education outl...

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) confer substantial morbidity and mortality, and have no specific therapy. The accessibility of the distal lung epithelium via the airway route, and the relatively transient nature of ALI/ARDS, suggest that the disease may be amenable to gene-based therapies. Ongoing advances in our understanding of the pathophysiology of ALI...

Activation of the coagulation cascade resulting in alveolar fibrin deposition is recognized as a hallmark of acute lung injury (ALI). Anticoagulant treatment with recombinant human activated protein C (rhAPC) appears promising, because - like in sepsis - there is a deficiency of protein C in ALI, which is correlated with poor outcome in both syndromes. Recently in Critical Care, Waerhaug and co...

BACKGROUND Sepsis could induce indirect acute lung injury(ALI), and pulmonary vasomotor dysfunction. While low tidal volume is advocated for treatment of ALI patients. However, there is no evidence for low tidal volume that it could mitigate pulmonary vasomotor dysfunction in indirect ALI. Our study is to evaluate whether low tidal volume ventilation could protect the pulmonary vascular functio...

We solve the integral equation describing the propagation of light in an isothermal plane-parallel atmosphere of optical thickness τ∗, adopting a uniform thermalization parameter ǫ. The solution given by the ALI method, widely used in the field of stellar atmospheres modelling, is compared to the exact solution. Graphs are given that illustrate the accuracy of the ALI solution as a function of ...

VEGFs and their receptors have been implicated in the regulation of vascular permeability in many organ systems, including the lung. Increased permeability and interstitial and pulmonary edema are prominent features of acute lung injury (ALI)/acute respiratory distress syndrome (ARDS). Extrapolating data from other organ systems and animal experiments have suggested that overexpression of VEGF ...

BACKGROUND Acute lung injury (ALI) is characterized by rapid induction of inflammation at the alveolar-capillary membrane, and immunosuppressive mechanisms were shown to contribute to its resolution. Despite the central role of lymphocytes in initiating and mediating an inflammatory response, their influx dynamics in ALI has not been examined. METHODS We collected mini-BAL samples from the lu...

Transcription factor cAMP response element modulator (CREM)α contributes to various cellular and molecular abnormalities in T cells, including increased IL-17 and decreased IL-2 expression. For development of acute lung injury (ALI), the invasion and regulation of immune cells are highly important, but the role of T cells remains unclear. In this study, we show that CREMα is upregulated in LPS-...

Pulmonary surfactant abnormalities have consistently been documented in patients with acute lung injury (ALI), however, there is little evidence directly correlating them to altered respiratory mechanics. To explore this further, surfactant composition was measured in lung aspirate fluid collected on 15 occasions from 10 patients with ALI. The composition was compared with lung aspirate fluid f...
