Using phage to detect phospho-tau at position 217
No full textAlzheimer's Disease (AD) remains mostly undiagnosed in the early stages of the disease.
• By the time that AD is clinically observed, it is thought that the damage done to the brain is too severe to be reversible.
• There is significant research suggesting AD-mediated changes to tau exist such as phosphorylation, oxidation, proteolysis and others
• Furthermore, recent data have shown that hyperphosphorylation on the tau protein is a critical post-translational modification (PTM) in AD that appear to manifest up to decades before clinical diagnosis.
• Specifically, tau phosphorylated at the 217-threonine position has shown promising results in other studie

Understanding the significance of the social determinants of health on the outcome of complicated surgical neonates at Red Cross War Memorial Children's Hospital
No full textIncludes bibliographical references.The United Nations Millennium Declaration conference held in September of 2000, set key Millennium Development Goals. Millennium Development Goal 4 requires a reduction in the mortality rate of children under the age of five years by two-thirds by the year 2015, from a baseline in 1990. In South Africa, it has been recognised that without a substantial reduction in neonatal deaths, MDG-4 will not be met. This study will focus on the social determinants of health which play a key role in neonatal outcome in South Africa. It will evaluate the effects of these social determinants of health (Primary caregiver's education level, Primary caregiver's age, and Living Standards Measure) on the outcome of neonates admitted to, and operated on, in the general surgery unit of Red Cross War Memorial Children's Hospital (RCWMCH), within the Western Cape, South Africa. This study is based on the hypothesis that there is an association between Neonatal outcome, and a selection of social variables, namely: primary caregiver's level of education, primary caregiver' age, and LSM. The protocol (Part A) describes the sampling methodology that was used during the intervention. This will be followed by a literature review (Part B), Article (Part C), and Appendix (Part D)
Critical study of the vertical-cavity surface emitting laser electrical access for integrated optical sub-assembly
No full textThe proposal contribution aims at highlighting the consequence of the impedance mismatching in Vertical-Cavity Surface-Emitting laser (VCSEL)-based optical subassembly for optical interconnection applications. The integration of this micro laser diode needs a particular care to avoid electromagnetic coupling which could transform the advantage of the VCSEL technology in a weakness. Indeed, the vertical emission perpendicular to the active layer gives the possibility to achieve the need of planarization of the optoelectronic circuits and the design of VCSEL arrays. That is why it is of great interest to develop an optoelectronic model including the electrical access effect. This model is based on the VCSEL rate equation comparison with a behavioural small-signal equivalent circuit. Scattering parameters of various VCSEL structures and various VCSEL chip submounts are tested. This characterization allows the validation of the laser model and emphasizes the influence of the electrical access in the light transmission. In a particular VCSEL array structure, a crosstalk phenomenon is also observed. In other cases, the frequency rise involves modification of the laser frequency response. Consequently the electrical access of the VCSEL needs to be improved in order to avoid an inadequate utilization of the VCSEL
Rodney King and the Decriminalization of Police Brutality in America: Direct and Judicial Access to the Grand Jury as Remedies for Victims of Police Brutality when the Prosecutor Declines to Prosecute
No full textThis Article begins with the premise that, despite political rhetoric and occasional prosecutions to the contrary, police brutality has been effectively decriminalized in this country. The Article adopts the Rodney King case as the paradigm for examining this phenomenon. Scrutinizing the culture and semantics of police brutality, the author concludes that a double standard of criminality exists in the United States, under which different rules apply to a police than to everyone else. This double standard is socially dysfunctional. Particularly among minorities, it leads to a sense of cynicism about our legal system that can result in civil disorder when properly fueled. More importantly, this double standard is morally wrong.
Because existing measures, including civil suits and civilian review boards, have failed to deter police misconduct, the author suggests that only the realistic threat of criminal prosecution will actually deter police violence. Unfortunately, the close working relationship between the place and prosecutors continues to make it extremely unlikely that many prosecutors will ever mount a credible challenge to systemic police brutality. Although, at first glance, traditional judicial deference to prosecutorial discretion may appear to preclude other avenues for undertaking criminal prosecution of officers who engage in police brutality, the author suggests there is another approach-citizen access to the grand jury- that could help current imbalance. This Article examines the avenues available under current law by which victimized citizens may bring their cases before the grand jury, either directly or through the impaneling judge, even when such action is opposed by the public prosecutor. The author concludes that he only reason that citizens have pursued this option so infrequently is that neither the bar nor the general public is aware of it. Thus, the goal of the Article is to analyze the pertinent law and provide practicing attorneys- and their clients- with information on procedures for gaining access to the grand jury in their jurisdictions

The combined effects of airflow and carbon dioxide on chrysanthemum, dwarf wheat, and soybean
No full textEffects of airflow direction and velocity on plant vegetative production were studied. Three plant species were studied: dwarf wheat (Triticum aestivum), chrysanthemum (Chrysanthemum morifolium), and soybean (Glycine max. L.). Specific objectives of this research were to: (1) Evaluate and improve environmental uniformity within plant growth chambers related to airflow velocity, airflow patterns, and CO\sb2 availability. (2) Quantify effects of horizontal airflow velocity at ambient and enriched CO\sb2, and horizontal versus vertical airflow patterns on plant vegetative growth.A literature review summarizes previous studies on the effects of airflow on plant heat and mass transfer, as well as on mechanical stresses caused by airflow and their effect on plant growth and quality.The development of a proportional and a proportional + integral (PI) CO\sb2 controller is described in detail, including the equipment used and control algorithms. The developed controllers maintained average CO\sb2 concentrations over a 12 hour period to within 3 and 1 mol mol\sp{-1} of set point for the proportional and PI controllers, respectively.Simple chambers were designed to test effects of 0.4, 0.8, and 1.5 m s\sp{-1} airflow velocity on soybeans. Results indicated that velocities between 0.4 and 1.5 m s\sp{-1} affected node number, height, and stem mass after 2 weeks of treatment, but that the plants were of similar size after 4 weeks of treatment.Experiments were performed to compare effects of horizontal and vertical airflow without CO\sb2 enrichment and horizontal airflow with 600 mol mol\sp{-1} CO\sb2 on dwarf wheat, chrysanthemum, and soybean. Soybean had larger leaf and whole plant relative growth rates (RGR) in vertical compared to horizontal airflow, while chrysanthemum had suppressed leaf and plant RGR in vertical compared to horizontal airflow. Vertical airflow appeared to cause mechanical stress in wheat, but evidence of mechanical stress was inconclusive for the other two species.Made available in DSpace on 2011-05-07T14:23:56Z (GMT).
