Development And Characterization Of Anti-Nitr9 Antibodies, Radhika N. Shah, Ivan Rodriguez-Nunez, Donna D. Eason, Robert N. Haire, Julien Y. Bertrand, Valērie Wittamer, David Traver, Shila K. Nordone

Pediatrics Faculty Publications

The novel immune-type receptors (NITRs), which have been described in numerous bony fish species, are encoded by multigene families of inhibitory and activating receptors and are predicted to be functional orthologs to the mammalian natural killer cell receptors (NKRs). Within the zebrafish NITR family, nitr9 is the only gene predicted to encode an activating receptor. However, alternative RNA splicing generates three distinct nitr9 transcripts, each of which encodes a different isoform. Although nitr9 transcripts have been detected in zebrafish lymphocytes, the specific hematopoietic lineage(s) that expresses Nitr9 remains to be determined. In an effort to better understand the role of …

Advancing Our Understanding Of The Inheritance And Transmission Of Pectus Excavatum, Lisa Horth, Michael W. Stacey, Virginia K. Proud, Kara Segna, Chelsea Rutherford, Donald Nuss, Robert E. Kelly

Bioelectrics Publications

Pectus excavatum is the most common congenital chest wall abnormality expressed in children, yet its inheritance is poorly understood. Here we present the first comprehensive assessment of the inheritance of this disorder. After evaluating 48 pedigrees and 56 clinical traits of probands and family members, we find strong evidence of autosomal recessive, genetic control for this disorder. Additionally there is likely more than one pectus disease-associated allele, as well as a relatively large number of disease allele carriers in the human population. Some clinical traits appear important and may serve as reliable indicators for predicting the likelihood of pectus excavatum …

The age of adolescence is the time when most adolescents in the world begin to be sexually active with resultant millions of pregnancies and sexually transmitted diseases (STDs). This chapter considers methods of contraception for these adolescents, including oral contraceptives, transdermal contraception, minipills, intra-vaginal ring, injectable contraception, intrauterine devices (IUDs), barrier contraceptives, implants, and others. It is important for clinicians caring for sexually active youth to provide information regarding contraception and appropriate contraceptive prescriptions.

Community Based Weighing Of Newborns And Use Of Mobile Phones By Village Elders In Rural Settings In Kenya: A Decentralised Approach To Health Care Provision, Peter Gisore, Evelyn Shipala, Kevin Otieno, Betsy Rono, Irene Marete, Constance Tenge, Hillary Mabeya, Sherri Bucher, Janet Moore, Edward Liechty, Fabian Esamai

Paediatrics and Child Health, East Africa

Background: Identifying every pregnancy, regardless of home or health facility delivery, is crucial to accurately estimating maternal and neonatal mortality. Furthermore, obtaining birth weights and other anthropometric measurements in rural settings in resource limited countries is a difficult challenge. Unfortunately for the majority of infants born outside of a health care facility, pregnancies are often not recorded and birth weights are not accurately known. Data from the initial 6 months of the Maternal and Neonatal Health (MNH) Registry Study of the Global Network for Women and Children’s Health study area in Kenya revealed that up to 70% of newborns did …

Augmented Annotation And Orthologue Analysis For Oryctolagus Cuniculus: Better Bunny, Douglas B. Craig, Sujatha Kannan, Alan A. Dombkowski

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The rabbit is an important model organism used in a wide range of biomedical research. However, the rabbit genome is still sparsely annotated, thus prohibiting extensive functional analysis of gene sets derived from whole-genome experiments. We developed a web-based application that provides augmented annotation and orthologue analysis for rabbit genes. Importantly, the application allows comprehensive functional analysis through the use of orthologous relationships.

Results

Using data extracted from several public bioinformatics repositories we created Better Bunny, a database and query tool that extensively augments the available functional annotation for rabbit genes. Using the complete set of target genes …

Use Of A Video Game Based Balance Training Intervention On The Balance And Function Of Children With Developmental Disabilities, Gina C. Siconolfi-Morris

Theses and Dissertations--Rehabilitation Sciences

Many children with developmental disabilities (DD) have physical impairments and limitations in their participation. Rehabilitation research often focuses on either physical impairments or participation restrictions, when both need to be investigated. The purposes of these two studies were to evaluate an at home therapist directed video game balance training intervention on balance, gait velocity (GV), hip strength and activities of children with DD. The pilot study was a single-subject non-concurrent multiple baseline design. Balance measures included: weight bearing symmetry; center of pressure area and velocity; time to boundary mean minima and standard deviation; and timed up and go. The participant’s …
