Arsenic Transport By Zebrafish Aquaglyceroporins, Mohamad Hamdi, Marco A. Sanchez, Lauren C. Beene, Qianyong Liu, Scott M. Landfear, Barry P. Rosen, Zijuan Liu

HWCOM Faculty Publications

Background

Arsenic is one of the most ubiquitous toxins and endangers the health of tens of millions of humans worldwide. It is a mainly a water-borne contaminant. Inorganic trivalent arsenic (As^III) is one of the major species that exists environmentally. The transport of As^III has been studied in microbes, plants and mammals. Members of the aquaglyceroporin family have been shown to actively conduct As^III and its organic metabolite, monomethylarsenite (MAs^III). However, the transport of As^III and MAs^III in in any fish species has not been characterized.

Automatic Recognition Of Frog Calls Using A Multi-Stage Average Spectrum, Wen-Ping Chen, Song-Shyong Chen, Chun-Cheng Lin, Ya-Zhung Chen, Wen-Chih Lin

Bioacoustics Collection

The automatic recognition of animal sounds is one of the powerful techniques for replacing the traditional ecological survey method that mainly depends on manpower, which is hence both costly and time consuming. This study developed an automatic frog call recognition system based on the combination of a pre-classification method of the syllable lengths and a multi-stage average spectrum (MSAS) method. In this system, the input frog syllables are first classified into one of the four groups determined by the pre-classification method according to syllable length. Then the proposed MSAS method is used to extract the standard feature template to analyze …

Fallow Bucks Get Hoarse: Vocal Fatigue As A Possible Signal To Conspecifics, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Many studies of sexually selected vocal communication assume that calls remain stable throughout the breeding season. However, during this period, physiological and social factors change and these can have strong effects on the structure of calls and calling rates. During the rut, fallow bucks, Dama dama, reduce their feeding and increase the time and energy spent on vocalizing and fighting to gain matings, and consequently their body condition declines greatly. The availability of matings and intensity of competition between males also change. Therefore, we predicted that male vocal signalling would vary over time in response to the changing intersexual and …

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon

Aquaculture Collection

A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. Noxiously stimulated fish did not show antipredator responses, suggesting that pain is the imperative. In the social status experiment, noxiously stimulated fish held individually and undisturbed showed an increase in respiration rate and plasma cortisol. As a comparison, we used the dominant or subordinate fish …

The Effects Of The Acetic Acid “Pain” Test On Feeding, Swimming, And Respiratory Responses Of Rainbow Trout (Oncorhynchus Mykiss): A Critique On Newby And Stevens (2008), Lynne U. Sneddon

Experimentation Collection

Newby and Stevens’ (2008) paper ‘‘The effects of the acetic acid ‘pain’ test on feeding, swimming, and respiratory responses of rainbow trout (Oncorhynchus mykiss)’’ examines the effects of a noxious stimulus on the behaviour of trout in an attempt to replicate research conducted in my laboratory (Sneddon, 2003a; Sneddon, 2007; Sneddon et al., 2003a,b; Reilly et al., 2008). However, the authors used a different protocol to the one already published and I would like to respond to some of their points of discussion to provide scientific explanations for their results using data from my laboratory. The authors show that swimming …

Feedyard Assessment: Assessor's Guide

Nebraska Beef Quality Assurance Program

The BQA Feedyard Assessment is an on-site educational tool that allows for assessing and benchmarking key indicators of animal care and well-being as well as feedyard conditions. The Feedyard Assessment focuses on three main areas – Animals, Records and Best Management Practices (BMP), and Facilities and Equipment.

Stocker And Backgrounding Self Assessment

Nebraska Beef Quality Assurance Program

Cattlemen in stocker operations have long recognized the need to properly care for livestock. Sound animal husbandry practices, based on decades of practical experience and research, are known to impact the well-being of stocker cattle, individual animal health and herd productivity. Stocker cattle operations are located in many diverse environments and geographic locations in the United States. A universal set of production practices can not be recommended for all stocker cattle producers in light of the divergent climate and geographic variations of the stocker and backgrounding segment. Personal experience, training and professional judgment can serve as a valuable resource for …

Primate Phylogenomics: Developing Numerous Nuclear Non-Coding, Non-Repetitive Markers For Ecological And Phylogenetic Applications And Analysis Of Evolutionary Rate Variation, Zuogang Peng, Navin Elango, Derek E. Wildman, Soojin V. Yi

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Genetic analyses are often limited by the availability of appropriate molecular markers. Markers from neutrally evolving genomic regions may be particularly useful for inferring evolutionary histories because they escape the constraints of natural selection. For the majority of taxa however, obtaining such markers is challenging. Advances in genomics have the potential to alleviate the shortage of neutral markers. Here we present a method to develop numerous markers from putatively neutral regions of primate genomes.

Development And Evaluation Of New Mask Protocols For Gene Expression Profiling In Humans And Chimpanzees, Donna M. Toleno, Gabriel Renaud, Tyra G. Wolfsberg, Munirul Islam, Derek E. Wildman, Kimberly D. Siegmund, Joseph G. Hacia

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Cross-species gene expression analyses using oligonucleotide microarrays designed to evaluate a single species can provide spurious results due to mismatches between the interrogated transcriptome and arrayed probes. Based on the most recent human and chimpanzee genome assemblies, we developed updated and accessible probe masking methods that allow human Affymetrix oligonucleotide microarrays to be used for robust genome-wide expression analyses in both species. In this process, only data from oligonucleotide probes predicted to have robust hybridization sensitivity and specificity for both transcriptomes are retained for analysis.

To characterize the utility of this resource, we applied our mask protocols …

The Guinea Pig Ileum Lacks The Direct, High-Potency, M2-Muscarinic, Contractile Mechanism Characteristic Of The Mouse Ileum, Michael T. Griffin, Minoru Matsui, Rennolds S. Ostrom, Frederick J. Ehlert

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

We explored whether the M2 muscarinic receptor in the guinea pig ileum elicits a highly potent, direct-contractile response, like that from the M3 muscarinic receptor knockout mouse. First, we characterized the irreversible receptor-blocking activity of 4-DAMP mustard in ileum from muscarinic receptor knockout mice to verify its M3 selectivity. Then, we used 4-DAMP mustard to inactivate M3 responses in the guinea pig ileum to attempt to reveal direct, M2 receptor-mediated contractions. The muscarinic agonist, oxotremorine-M, elicited potent contractions in ileum from wild-type, M2 receptor knockout, and M3 receptor knockout mice characterized by negative log EC50 (pEC 50 ) values ± …
