The effect of mild sleep restriction on cognitive functioning in young children is unclear, yet sleep loss may impact children's abilities to attend to tasks with high processing demands. In a preliminary investigation, six children (6.6 - 8.3 years of age) with normal sleep patterns performed three tasks: attention (“Oddball”), speech perception (conconant-vowel syllables) and executive function (Directional Stroop). Event-related potentials (ERP) responses were recorded before (Control) and following one-week of 1-hour per day of sleep restriction. Brain activity across all tasks following Sleep Restriction differed from activity during Control Sleep, indicating that minor sleep restriction impacts children's neurocognitive functioning.

Center for Brain, Biology, and Behavior: Faculty and Staff Publications
Typically developing (TD) preschoolers and age-matched preschoolers with specific language impairment (SLI) received event-related potentials (ERPs) to four monosyllabic speech sounds prior to treatment and, in the SLI group, after 6 months of grammatical treatment. Before treatment, the TD group processed speech sounds faster than the SLI group. The SLI group increased the speed of their speech processing after treatment. Post-treatment speed of speech processing predicted later impairment in comprehending phrase elaboration in the SLI group. During the treatment phase, change in speed of speech processing predicted growth rate of grammar in the SLI group.
Heifers With Low Antral Follicle Counts Have Low Birth Weights And Produce Progeny With Low Birth Weights, Adam F. Summers, Robert A. Cushman, Karl Moline Moline, Jeff Bergman, Andrea S. Cupp
Heifers With Low Antral Follicle Counts Have Low Birth Weights And Produce Progeny With Low Birth Weights, Adam F. Summers, Robert A. Cushman, Karl Moline Moline, Jeff Bergman, Andrea S. Cupp
Nebraska Beef Cattle Reports
To determine the relationship of antral follicle count and heifer BW, reproductive tract characteristics, and first-calf performance, Red Angus-composite heifers were used over three years. High antral follicle count heifers had greater BW from birth through pre-breeding. Progeny birth BW was greater for calves born to high antral follicle count heifers compared to low antral follicle count heifers. Taken together these data indicate a relationship between antral follicle counts and BW through the first breeding season and corresponding progeny, and continues to support a possible link between genes that influence growth and development and establishment of ovarian reserve.
Effect Of Two Estrus Synchronization Protocols On Reproductive Performance Of May Calving Cows, John D. Harms, Adam F. Summers, Jacqueline Musgrave Musgrave, Rick Funston
Effect Of Two Estrus Synchronization Protocols On Reproductive Performance Of May Calving Cows, John D. Harms, Adam F. Summers, Jacqueline Musgrave Musgrave, Rick Funston
Nebraska Beef Cattle Reports
The objective of this experiment was to determine the effectiveness of fixed-time AI utilizing one of two estrus synchronization protocols, CO-Synch or CO-Synch + CIDR, in May-calving cows. Cows synchronized with the CO-Synch + CIDR protocol had increased AI and overall pregnancy rates compared to cows synchronized utilizing the CO-Synch protocol. Due to increased AI pregnancy rates, CO-Synch + CIDR cows calved earlier, resulting in a greater proportion of cows calving within the first 21 days of the calving season compared to CO-Synch cows.

Efficacy Of Newborn Bovine Dna Samples Taken Via Different Mediums In Assigning Paternity, Jeremy T. Howard, Lynsey K. Whitacre, Matthew L. Spangler Spangler
Nebraska Beef Cattle Reports
DNA samples from 25 newborn calves taken via hair, ear notch, and nasal swabs were used to determine the efficacy of sampling method in assigning parentage. Nasal swab samples were collected at six time points from birth to 120 hours post-birth. Calf samples and all candidate sires were genotyped with a 99 SNP parentage panel. Nasal swab collection time did not result in significant differences in the ability to assign the correct sire, although differences were seen in apparent cleanliness of the sample. Clean nasal swab samples are comparable in efficacy to hair and ear notch samples in assigning parentage.

Effect Of Winter Supplementation Level On Yearling System Profitability, Kari L. Gillespie, Brandon L. Nuttelman, Cody J. Schneider Schneider, Terry J. Klopfenstein
Nebraska Beef Cattle Reports
Calves backgrounded in a forage-based system at a high winter supple- mentation level maintained a performance advantage through finishing. High level supplemented cattle gained an additional 0.2 lb. daily during finishing, consumed less total feed in the feedlot, required fewer days on feed to reach a common finish point and produced an additional 85 lb. of saleable live weight compared to cattle backgrounded at a low supplementation level. High level supplemented cattle returned $56.01 more than cattle fed a low level of supplementation during the winter backgrounding phase.

Nitrogen Fertilization And Ddgs Supplementation Reduces Annual Weeds In Pastures, John A. Guretzky, Laura K. Snell, John C. Soper Soper, Walter H. Schacht, Terry Klopfenstein, Stephanie K. Pruitt
Nebraska Beef Cattle Reports
Ongoing research has found body weight (BW) gains of steers supplemented with corn dried distillers grains plus solubles (DDGS) on unfertilized smooth bromegrass pasture (SUPP) to be greater than unsupplemented steers on N fertilized (FERT) and unfertilized, control (CONT) smooth bromegrass pasture. In the seventh year of the study, annual weeds increased to 20%, 9%, and 2% of relative cover within CONT, SUPP, and FERT pastures, respectively. Supplementation of DDGS on unfertilized pastures improves steer BW gains and reduces N inputs while providing intermediate resistance to annual weed invasion. AnnualN fertilization maximizes forage yield and minimizes annual weeds in pasture.

Effects Of Feeding Microbial Feed Additives On Growth Performance And Carcass Traits Of Steers Fed Steam-Flaked Corn-Based Diets With Wet Distillers Grains Plus Solubles, Matt K. Luebbe, Karla H. Jenkins, Stephanie A. Furman Furman, Kelly K. Kreikemeier
Nebraska Beef Cattle Reports
An experiment was conducted to determine the effects of feeding two commercially available direct-fed microbials (DFM) on finishing steer performance fed steam-flaked corn based diets. Dietary treatments included a control diet without DFM, and two commercially available products (10-G and Bovamine). No significant differences were observed among treatments for animal performance or carcass characteristics. However, numeric advantages were observed for ADG and feed efficiency when cattle were fed a DFM.

Twenty-four worms were collected from the bronchioles in both lungs of a male nine-banded armadillo Dasypus novemcinctus Linnaeus, 1758 captured in Teacalco, Morelos, Mexico. The worms, herein named Metathelazia mexicana n. sp., show a constriction in the esophagus at the level of the nerve ring; males of the species have 7 pairs of papillae, fewer than the other species in the genus. Metathelazia capsulata is the most similar species to Metathelazia mexicana; however, the latter has much shorter spicules. This is the fourth species in the genus known to occur in the New World.

Brucellosis is the one of most common livestock zoonoses in Georgia, resulting in significant economic losses. Livestock were sampled in three regions of Georgia (Kakheti, Kvemo Kartli, Imereti). Districts that historically reported high numbers of brucellosis related morbidity were selected for serological, bacteriological and molecular surveys. Surveying efforts yielded samples from 10,819 large and small ruminants. In total, 735 serological tests were positive on Rose Bengal and 33 bacterial isolates were recovered and identified as Brucella melitensis or Brucella abortus by microbiology and AMOS-PCR. A Bayesian framework was implemented to estimate the true prevalence of the disease given an imperfect …

Plagioscion squamosissimus (Heckel, 1840) (Osteichthyes: Sciaenidae) is considered piscivorous and is a generalist species endemic to the Amazon region. This fish is an important part of the natural ecosystems in which it occurs and provides basic functional components in the food web. The genus Neoechinorhynchus Stiles & Hassall, 1905 is distributed worldwide and parasitizes fish and turtles, but there are few reports of parasites of this genus in South America, due to the high diversity of fish that can be found in this region. A new species of thorny-headed worm (Acanthocephala: Neoechinorhynchidae) is described from P. squamosissimus from Guajará Bay, …
On The Morphology And Taxonomy Of Griphobilharzia Amoena Platt And Blair, 1991 (Schistosomatoidea), A Dioecious Digenetic Trematode Parasite Of The Freshwater Crocodile, Crocodylus Johnstoni, In Australia [Critical Comment], Thomas R. Platt, Eric P. Hoberg, Leslie A. Chisholm
On The Morphology And Taxonomy Of Griphobilharzia Amoena Platt And Blair, 1991 (Schistosomatoidea), A Dioecious Digenetic Trematode Parasite Of The Freshwater Crocodile, Crocodylus Johnstoni, In Australia [Critical Comment], Thomas R. Platt, Eric P. Hoberg, Leslie A. Chisholm
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Griphobilharzia amoena Platt and Blair, 1991 was originally described was originally described as a dioecious trematode, parasitic in the circulatory system of the Australian freshwater crocodile, Crocodylus johnstoni, with the female completely enclosed in a gynecophoric chamber of the male and the two worms orientated anti-parallel to each other. A recent publication questions the original description, arguing that G. amoena is monoecious and, as a consequence, the species was transferred to Vasotrema Stunkard, 1928 (Spirorchiidae) as Vasotrema amoena n. comb. We provide photomicrographic evidence that the original description of G. amoena is correct and that Griphobilharzia Platt and Blair, …

Background: The Per-Arnt-Sim (PAS) domain represents a ubiquitous structural fold that is involved in bacterial sensing and adaptation systems, including several virulence related functions. Although PAS domains and the subclass of PhoQ-DcuS-CitA (PDC) domains have a common structure, there is limited amino acid sequence similarity. To gain greater insight into the evolution of PDC/PAS domains present in the bacterial kingdom and staphylococci in specific, the PDC/PAS domains from the genomic sequences of 48 bacteria, representing 5 phyla, were identified using the sensitive search method based on HMM-to-HMM comparisons (HHblits).
Results: A total of 1,007 PAS domains and 686 …

Characterizing and understanding the complex spectrum of lipids in higher organisms lags far behind our analysis of genome and transcriptome sequences. Here we generate and evaluate comprehensive lipid profiles (>200 lipids) of 92 inbred lines from five different Drosophila melanogaster populations. We find that the majority of lipid species are highly heritable, and even lipids with odd-chain fatty acids, which cannot be generated by the fly itself, also have high heritabilities. Abundance of the endosymbiont Wolbachia, a potential provider of odd-chained lipids, was positively correlated with this group of lipids. Additionally, we show that despite years of laboratory …

Conformational B-Cell Epitope Prediction On Antigen Protein Structures: A Review Of Current Algorithms And Comparison With Common Binding Site Prediction Methods, Bo Yao, Dandan Zheng, Shide Liang, Chi Zhang
School of Biological Sciences: Faculty Publications
Accurate prediction of B-cell antigenic epitopes is important for immunologic research and medical applications, but compared with other bioinformatic problems, antigenic epitope prediction is more challenging because of the extreme variability of antigenic epitopes, where the paratope on the antibody binds specifically to a given epitope with high precision. In spite of the continuing efforts in the past decade, the problem remains unsolved and therefore still attracts a lot of attention from bioinformaticists. Recently, several discontinuous epitope prediction servers became available, and it is intriguing to review all existing methods and evaluate their performances on the same benchmark. In addition, …

As part of an interdepartmental effort to attract promising young students to research at the interface between mathematics and biology, we created a course in which groups of recent high school graduates and first-year college students conducted a research project in insect population dynamics. The students set up experiments, collected data, used the data to develop mathematical models, tested their models against further experiments, and prepared their results for dissemination. The course was self-contained in that the lecture portion developed the mathematical, statistical, and biological background needed for the research. A special writing component helped students learn the principles of …

Post-operative increases in circulating bile acids have been suggested to contribute to the metabolic benefits of bariatric surgery; however, their mechanistic contributions remain undefined. We have previously reported that ileal interposition (IT) surgery delays the onset of type 2 diabetes in UCD-T2DM rats and increases circulating bile acids, independently of effects on energy intake or body weight. Therefore, we investigated potential mechanisms by which post-operative increases in circulating bile acids improve glucose homeostasis after IT surgery. IT, sham or no surgery was performed on 2-month-old weight-matched male UCD-T2DM rats. Animals underwent an oral fat tolerance test (OFTT) and serial oral …

Bats are hosts to a range of zoonotic and potentially zoonotic pathogens. Human activities that increase exposure to bats will likely increase the opportunity for infections to spill over in the future. Ecological drivers of pathogen spillover and emergence in novel hosts, including humans, involve a complex mixture of processes, and understanding these complexities may aid in predicting spillover. In particular, only once the pathogen and host ecologies are known can the impacts of anthropogenic changes be fully appreciated. Cross-disciplinary approaches are required to understand how host and pathogen ecology interact. Bats differ from other sylvatic disease reservoirs because of …

Dirofilariosis In The Americas: A More Virulent Dirofilaria Immitis?, Filipe Dantas-Torres, Domenico Otranto
Harold W. Manter Laboratory: Library Materials
Dirofilarioses are widespread diseases caused by filarioid nematodes (superfamily Filarioidea) of the genus Dirofilaria, which are transmitted by a plethora of mosquito species. The principal agent of canine dirofilariosis in the Americas is Dirofilaria immitis, which may also occasionally infest humans, resulting in pulmonary nodules that may be confounded with malignant lung tumours. Because human cases of dirofilariosis by D. immitis are relatively frequent in the Americas and rare in Europe and other eastern countries, where Dirofilaria repens is the main causative agent, the existence of a more virulent strain of D. immitis in the Americas …

Parasitism is composed by three subsystems: the parasite, the host, and the environment. There are no organisms that cannot be parasitized. The relationship between a parasite and its host species most of the time do not result in damage or disease to the host. However, in a parasitic disease the presence of a given parasite is always necessary, at least in a given moment of the infection. Some parasite species that infect humans were inherited from pre-hominids, and were shared with other phylogenetically close host species, but other parasite species were acquired from the environment as humans evolved. Human migration …

Nematodes are the most speciose phylum of metazoa on earth. Not only do they occur in huge numbers as parasites of all known animal groups, but also they are found in the soils, as parasites of plants, and in large numbers in the most extreme environments, from the Antarctic dry valleys to the benthos of the ocean.
