Research Publications (2011 to 2015)

The cytochrome oxidase subunit I (COXI) gene sequences of three recent (20072008) clinical Plasmodium knowlesi isolates from Klang Valley, peninsular Malaysia, were determined and compared with those of older (1960's) peninsular Malaysia, recent isolates from Sarawak (on Borneo Island), and an isolate from Thailand. Multiple alignment of the sequences showed that the three clinical isolates were more similar to the older peninsular Malaysia isolates than to those from Sarawak and Thailand. Phylogenetic tree based on the COXI sequences revealed three distinct clusters of P. knowlesi. The first cluster consisted of isolates from peninsular Malaysia, the second consisted of Sarawak isolates …

Research Publications (2011 to 2015)

Glucoamylase (EC 3.2.1.3) from Aspergillus niger was used to hydrolyze commercial sago starch into reducing sugars. The energetics of the hydrolysis was studied at optimal substrate concentration, enzyme amount and pH for the process. The ΔH and ΔS estimated via van't Hof analysis were 7.9 J.mole -1 and 6.2 J.mole -1.K -1, respectively. The results indicated that the hydrolysis process is an endothermic reaction and spontaneous within the temperature range tested. It is calculated that 26.3 J.mole -1 of activation energy, E a is required for the enzymatic conversion of sago starch into reducing sugars. The spontaneous reaction with relatively …

Spasmolytic Effect Of Citral And Extracts Of Cymbopogon Citratus On Isolated Rabbit Ileum, Ramachandran Chitra Devi, Si Mui Sim, Rosnah Ismail

Research Publications (2011 to 2015)

Cymbopogon citratus, commonly known as lemongrass, has been shown to have antioxidant, antimicrobial and chemo-protective properties. Citral, a monoterpenoid, is the major constituent of C. citratus that gives off a lemony scent and is postulated to be responsible for most of its actions. In addition, C. citratus has been traditionally used to treat gastrointestinal discomforts, however, the scientific evidence for this is still lacking. Thus, the aim of the present study was to investigate the effect of the extracts of various parts of C. citratus (leaves, stems and roots) and citral on the visceral smooth muscle activity of rabbit ileum. …

Research Publications (2011 to 2015)

Background: Mesenchymal stem cells (MSCs) represent a promising alternative form of cell-based therapy for cartilage injury. However, the capacity of MSCs for chondrogenesis has not been fully explored. In particular, there is presently a lack of studies comparing the effectiveness of MSCs to conventional autologous chondrocyte (autoC) treatment for regeneration of full-thickness cartilage defects in vivo. Hypothesis: Treatment with allogenic undifferentiated MSCs (alloMSCs) results in superior cartilage tissue regeneration profiles when compared with autoC for repair of focal articular cartilage defects. Study Design: Controlled laboratory study. Methods: Full-thickness articular cartilage defects were created on the weightbearing surface of the medial …

The Nature And Nurture Of Violence: Early Intervention Services For The Families Of Maoa-Low Children As A Means To Reduce Violent Crime And The Costs Of Violent Crime Note, Jennifer Brooks-Crozier Jan 2011

The Nature And Nurture Of Violence: Early Intervention Services For The Families Of Maoa-Low Children As A Means To Reduce Violent Crime And The Costs Of Violent Crime Note, Jennifer Brooks-Crozier

Connecticut Law Review

In 1993, scientist Hans Brunner discovered that several male members of a large Dutch family who exhibited behaviors such as impulsive aggression, arson, and attempted rape possessed a mutant copy of the MAOA gene, the gene that codes for the production of the enzyme monoamine oxidase A ("MAOA"). Brunner and his colleagues demonstrated that carrier males produced less MA OA, or were "MAOA-low. " They hypothesized that this MAA deficiency caused abnormal aggressive behavior in MAOA-low males. Subsequent research, however, demonstrated that the genetic mutation, acting alone, does not produce the abnormal, aggressive behavior observed by Brunner and his colleagues. …

Microclimate And Bat Occupation Trends At Gorman Cave, Colorado Bend State Park, San Saba County, Texas During 2010-2011. Jan 2011

Microclimate And Bat Occupation Trends At Gorman Cave, Colorado Bend State Park, San Saba County, Texas During 2010-2011.

KIP Articles

Bats are the only group of vertebrates that have successfully exploited caves for permanent shelter. Suitable bat caves are rare on karst landscapes because cave microclimate must provide certain temperature and humidity ranges for optimal metabolic regulation by roosting bats. Caves that are suitable for maternal bat colonies allow females to conserve stored energy and neonatal bats to develop and mature. Similarly, caves that are suitable as hibernacula allow bats optimal thermoregulation and survival during the cold season. Therefore, bat use at caves should be investigated and monitored, and caves important to long-term population viability should be protected. Colorado Bend …

Genetic Modulation Of Horizontal Cell Number In The Mouse Retina, Irene Whitney, Mary Raven, Daniel Ciobanu, Ross Poché, Qian Ding, Yasser Elshatory, Lin Gan, Robert Williams, Benjamin Reese

Department of Animal Science: Faculty Publications

Neuronal populations display conspicuous variability in their size among individuals, but the genetic sources of this variation are largely undefined. We demonstrate a large and highly heritable variation in neuron number within the mouse retina, affecting a critical population of interneurons, the horizontal cells. Variation in the size of this population maps to the distal end of chromosome (Chr) 13, a region homologous to human Chr 5q11.1–11.2. This region contains two genes known to modulate retinal cell number. Using conditional knock-out mice, we demonstrate that one of these genes, the LIM homeodomain gene Islet-1 (Isl1), plays a role …

Meaning Correlates Of Value Orientations, Shulamith Kreitler

Papers from the International Association for Cross-Cultural Psychology Conferences

The purpose was to explore the relations between value orientations and meaning assignment tendencies. The hypotheses were that values would be related to a certain number of meaning variables that would be similar in three cultural groups. The participants were 150 individuals of both genders living in Israel. They are from three cultural communities (50 participants each): Israeli, French, and Russian. They were administered the values inventory PQ IV by Schwartz (1992) and the Meaning Test by Kreitler and Kreitler (1990a). The relations between the values of hedonism, power, and benevolence and the meaning variables were analyzed by correlations. The …
