Association Of Brain-Derived Neurotrophic Factor (Val66met) Genetic Polymorphism With Methamphetamine Dependence In A Malaysian Population, Zahurin Mohamed 2009 University of Malaya

Association Of Brain-Derived Neurotrophic Factor (Val66met) Genetic Polymorphism With Methamphetamine Dependence In A Malaysian Population, Zahurin Mohamed

Zahurin Mohamed

Methamphetamine is a highly addictive psychostimulant that has surged in popularity worldwide in the last decade. Brain-derived neurotrophic factor (BDNF), a member of the neurotrophic factor family, is widely expressed in the adult mammalian brain and plays an important role in the long-term survival, differentiation, and outgrowth of neurons. Previous studies suggested that the BDNF gene may be involved in the mechanisms underlying substance dependence. This study investigated the association of the BDNF gene Val66Met polymorphism with methamphetamine dependence and with psychosis in a Malaysian population with different ethnicities. The BDNF Val66Met polymorphism was genotyped by PCR-RFLP in 186 male ...


Testing Soil Phytolith Analysis As A Tool To Understand Vegetation Change In The Sagebrush Steppe And Pinyon-Juniper Woodlands Of The Great Basin Desert, Usa, Neil E. West 2009 Utah State University

Testing Soil Phytolith Analysis As A Tool To Understand Vegetation Change In The Sagebrush Steppe And Pinyon-Juniper Woodlands Of The Great Basin Desert, Usa, Neil E. West

Neil E. West

Better biological proxy methods are needed to understand changes in arid ecosystems over the recent past. Our objective in this study was to examine the utility of soil phytolith analysis to reflect vegetation changes over the past 200 years, from the end of the 'Little Ice Age' to present. The sensitivity of phytoliths to record vegetation changes for this time period was tested by sampling in locations where vegetation changes were known to have occurred based on human records. We used extraction weights to test for the trend in reduction of grasses and increase in woody vegetation over time. We ...


Can Soil Phytolith Analysis And Charcoal Be Used As Indicators Of Historic Fire In The Pinyon-Juniper And Sagebrush Steppe Ecosystem Types Of The Great Basin Desert, Usa?, Neil E. West 2009 Utah State University

Can Soil Phytolith Analysis And Charcoal Be Used As Indicators Of Historic Fire In The Pinyon-Juniper And Sagebrush Steppe Ecosystem Types Of The Great Basin Desert, Usa?, Neil E. West

Neil E. West

Wildland fire intensity and area are increasing across the Intermountain West, USA, in a variety of ecosystem types including the pinyon-juniper woodlands and sagebrush steppe of the Great Basin Desert. Unfortunately, we do not know if there were historic analogues for these high-intensity stand-replacing fires because of the lack of fire scars that record evidence of them. Soil-charcoal and phytolith analyses have been successfully employed in other regions to garner information about fire regimes through the Holocene. We studied the utility of these methodologies and related taphonomic issues in soils in the Great Basin Desert...

High Cortisol Levels In The Offspring Of Parents With Bipolar Disorder During Two Weeks Of Daily Sampling, Jonathan Bruce Santo 2009 University of Nebraska at Omaha

High Cortisol Levels In The Offspring Of Parents With Bipolar Disorder During Two Weeks Of Daily Sampling, Jonathan Bruce Santo

Jonathan B. Santo

Objectives: The hypothalamic-pituitary-adrenal (HPA) axis is compromised in major depression, bipolar disorder (BD), and in the offspring of parents with major depression. Less is known about the offspring of parents with BD (FH+). The present project provides follow-up to a previous study showing that the adolescent (mean age 16.7 years) FH+ offspring had higher salivary cortisol levels than theoffspringofparentswithnomentaldisorder(FH))throughouttheday in their natural environment, and that girls had higher cortisol levels than boys (Ellenbogen MA, Hodgins S, Walker C-D, Adam S, Couture S. Daytime cortisol and stress reactivity in the offspring of parents with bipolar disorder. Psychoneuroendocrinology 2006 ...

Semiparametric Analysis Of Recurrent Events: Artificial Censoring, Truncation, Pairwise Estimation And Inference, Debashis Ghosh 2009 Penn State University

Semiparametric Analysis Of Recurrent Events: Artificial Censoring, Truncation, Pairwise Estimation And Inference, Debashis Ghosh

Debashis Ghosh

The analysis of recurrent failure time data from longitudinal studies can be complicated by the presence of dependent censoring. There has been a substantive literature that has developed based on an artificial censoring device. We explore in this article the connection between this class of methods with truncated data structures. In addition, a new procedure is developed for estimation and inference in a joint model for recurrent events and dependent censoring. Estimation proceeds using a mixed U-statistic based estimating function approach. New resampling-based methods for variance estimation and model checking are also described. The methods are illustrated by application to ...


Vertical Dispersal Of Aedes (Stegomyia) Spp. In High-Rise Apartments In Putrajaya, Malaysia, Mohd Sofian Bin Azirun 2009 Institute of Biological Sciences, Faculty of Science Building, University of Malaya, 50603 Kuala Lumpur, MALAYSIA

Vertical Dispersal Of Aedes (Stegomyia) Spp. In High-Rise Apartments In Putrajaya, Malaysia, Mohd Sofian Bin Azirun

Mohd Sofian Bin Azirun

A preliminary study on the vertical dispersal of Aedes populations in high-rise apartments was carried out in Presint 9, Putrajaya, Malaysia. Ovitraps were placed indoors within four blocks of high-rise apartments from the ground floors (0.0 - 3.0 m) until up to the tenth floors (28.1 - 30.0 m). Aedes aegypti was the dominant species found in the ovitraps (87.85%), while Aedes albopictus was found in lower numbers. From total number of larvae collected (650), 40.92% of these larvae were obtained from the fourth block; Block D. The peak density of Aedes sp. was observed at ...


Cow-Calf Producer Perceptions Regarding Individual Animal Traceability, Lee L. Schulz, Glynn T. Tonsor 2009 Kansas State University

Cow-Calf Producer Perceptions Regarding Individual Animal Traceability, Lee L. Schulz, Glynn T. Tonsor

Lee Schulz

This study provides valuable insights into cow-calf producer voluntary participation in the National Animal Identification System and producers’ perceptions of several issues critically impacting the success of voluntary traceability systems. Cow-calf producers believe that the most important issues to the U.S. beef industry in designing a national, individual animal traceability system are monitoring/managing disease, maintaining current foreign markets, accessing foreign markets, and increasing consumer confidence. Furthermore, producers are concerned with cost, liability, reliability of technology, failure of system to meet stated goals, and confidentiality of information associated with these systems.

Evaluation Of Measurement Procedures Used To Determine The Bulk Density Of Distillers Dried Grains With Solubles (Ddgs), Clairmont L. Clementson, Klein E. Ileleji, Kurt A. Rosentrater 2009 Purdue University

Evaluation Of Measurement Procedures Used To Determine The Bulk Density Of Distillers Dried Grains With Solubles (Ddgs), Clairmont L. Clementson, Klein E. Ileleji, Kurt A. Rosentrater

Kurt A. Rosentrater

The production of corn-based ethanol in the U.S. has been dramatically increasing in recent years, and consequently so has the quantity of co-products, especially distillers dried grains with solubles (DDGS), generated from this industrial sector. DDGS is sold as a commodity for animal feed, and like corn, its bulk physical and chemical properties are quality attributes that can be used in trading by merchandisers. Consistency in product quality has been a cause for concern in the industry, and the lack of standard methods for physical and chemical property determination potentially confounds the issue, especially when results of attributes measured ...

Reason And Desire: The Case Of Affective Desires, Attila Tanyi 2009 University of Liverpool

Reason And Desire: The Case Of Affective Desires, Attila Tanyi

Attila Tanyi

The paper begins with an objection to the Desire-Based Reasons Model. The argument from reason-based desires holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of this argument by Ruth Chang. Chang invokes a counterexample: affective desires. The aim of the paper is to see if there is a way to accommodate the counterexample to the first premise. I investigate three strategies. I first deal ...
