Cause Or Effect: Misregulation Of Microrna Pathways In Neurodegeneration, Eduardo Gascon, Fen-Biao Gao 2012 University of Massachusetts Medical School

Cause Or Effect: Misregulation Of Microrna Pathways In Neurodegeneration, Eduardo Gascon, Fen-Biao Gao

Neurology Publications

During normal aging or neurodegenerative diseases, neuronal survival and function depend on protein homeostasis, which is regulated by multiple mechanisms, including the microRNA (miRNA) pathway. In different cells types, the absence of Dicer, a key miRNA processing enzyme, leads to neurodegeneration through cell-autonomous and non-cell-autonomous mechanisms. Loss of certain miRNAs also causes neurodegeneration in some model organisms. On the other hand, miRNA expression is misregulated in patients with different neurodegenerative diseases. Thus, the miRNA pathway appears to be essential in the pathogenesis of several age-dependent neurodegenerative conditions; however, our understanding of the underlying mechanism remains rudimentary. The precise causal relationships ...


Cold Injury To Alfalfa, Stephen K. Barnhart 2012 Iowa State University

Cold Injury To Alfalfa, Stephen K. Barnhart

Integrated Crop Management News

Alfalfa fields are growing well across most of Iowa. The next few nights have frost or freeze warnings, with predictions of night low temperatures as low as low 20s. Low temperatures, whether visible frost is present or not, may affect the growth of both established forage plants, as well as newly emerged seedlings.


A Streamlined Dna Tool For Global Identification Of Heavily Exploited Coastal Shark Species (Genus Rhizoprionodon), D. Pinhal, Mahmood S. Shivji, Pedro G. Nachtigall, Demian D. Chapman, Cesar Martins 2012 Sao Paolo State University - Brazil

A Streamlined Dna Tool For Global Identification Of Heavily Exploited Coastal Shark Species (Genus Rhizoprionodon), D. Pinhal, Mahmood S. Shivji, Pedro G. Nachtigall, Demian D. Chapman, Cesar Martins

Marine & Environmental Sciences Faculty Articles

Obtaining accurate species-specific landings data is an essential step toward achieving sustainable shark fisheries. Globally distributed sharpnose sharks (genus Rhizoprionodon) exhibit life-history characteristics (rapid growth, early maturity, annual reproduction) that suggests that they could be fished in a sustainable manner assuming an investment in monitoring, assessment and careful management. However, obtaining species-specific landings data for sharpnose sharks is problematic because they are morphologically very similar to one another. Moreover, sharpnose sharks may also be confused with other small sharks (either small species or juveniles of large species) once they are processed (i.e., the head and fins are removed). Here ...


Determining When To Harvest First Crop Alfalfa In A Warm Spring, Brian J. Lang 2012 Iowa State University

Determining When To Harvest First Crop Alfalfa In A Warm Spring, Brian J. Lang

Integrated Crop Management News

The exceptionally warm spring has alfalfa growth well ahead of normal, with some farmers expecting to harvest first crop in April. Those that normally harvest first crop alfalfa by calendar date, often harvest in mid to late May. Harvest should be much sooner this spring, but when? Consider using the Predictive Equations of Alfalfa Quality (PEAQ) to determine when to harvest. PEAQ is a simple management tool to estimate alfalfa quality in the field to help predict the best time to harvest first crop.


The Context Of Gene Expression Regulation, Johan H. Gibcus, Job Dekker 2012 University of Massachusetts Medical School

The Context Of Gene Expression Regulation, Johan H. Gibcus, Job Dekker

Program in Gene Function and Expression Publications

Recent advances in sequencing technologies have uncovered a world of RNAs that do not code for proteins, known as non-protein coding RNAs, that play important roles in gene regulation. Along with histone modifications and transcription factors, non-coding RNA is part of a layer of transcriptional control on top of the DNA code. This layer of components and their interactions specifically enables (or disables) the modulation of three-dimensional folding of chromatin to create a context for transcriptional regulation that underlies cell-specific transcription. In this perspective, we propose a structural and functional hierarchy, in which the DNA code, proteins and non-coding RNAs ...


Pork Quality: Ph Decline And Pork Quality, Steven Lonergan 2012 Iowa State University

Pork Quality: Ph Decline And Pork Quality, Steven Lonergan

Animal Science White Papers, Technical Reports, & Fact Sheets

The properties of fresh and processed pork are dependent on factors related to composition of the product such as moisture, lipid and protein content. It is important to recognize, however, that it is not just the amount of these components, but rather the characteristics of protein, lipid and water that are responsible for differences in pork color, texture, water holding capacity and tenderness. In many cases, it is the proteins in pork that are primarily important in the variations that are observed in these traits. The state and nature of proteins are primarily responsible for pork color, pork texture, pork ...


Diversification Of Organic Cropping Systems With Cover Crop Mixtures: Influence On Weed Communities, Soil Microbial Community Structure, Soil Moisture And Nitrogen, And Crop Yield, Samuel E. Wortman 2012 University of Nebraska-Lincoln

Diversification Of Organic Cropping Systems With Cover Crop Mixtures: Influence On Weed Communities, Soil Microbial Community Structure, Soil Moisture And Nitrogen, And Crop Yield, Samuel E. Wortman

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Organic grain cropping systems typically depend on intensive mechanical cultivation for weed control and manure or compost applications to meet plant nutrient demands. However, cover crops may contribute to weed suppression and soil fertility, potentially increasing crop yield and sustainability of the system. The utility of individual cover crop species have been well documented, but the agronomic benefits of diverse cover crop mixtures have received less attention. Cover crop mixtures are an appealing option for farmers, as increasing species diversity has been shown to increase resource-use efficiency, stability, resiliency, and productivity of plant communities. Despite the growing interest in cover ...

Insecticidal Seed Treatments Can Harm Honey Bees, Erin W. Hodgson, Christian Krupke

Integrated Crop Management News

Neonicotinoids are a relatively new class of chemistry to control insects. They are now widely adopted because they are persistent and systemic in plant tissues. Most field crops in Iowa have a neonicotinoid seed treatment. Common examples of neonicotinoids include: clothianidin (Poncho ®), thiamethoxam (Cruiser ®), and imidacloprid (Gaucho ®). Active ingredient rates range from 0.25-1.25 milligrams per kernel (sold as 250-1,250 rates).

Centipedes And Millipeds (Arthropoda: Diplopoda, Chilopoda) From Saba Island, Lesser Antilles, And A Consolidation Of Major References On The Myriapod Fauna Of “Lesser” Caribbean Islands, Rowland M. Shelley, Derek S. Sikes

Insecta Mundi

The chilopod, Cryptops hortensis (Donovan, 1810) (Scolopendromorpha: Cryptopidae), and the diplopods, Pseudospirobolellus avernus (Butler, 1876) (Spirobolida: Pseudospirobolellidae) and Oxidus gracilis (C. L. Koch, 1847) (Polydesmida: Paradoxosomatidae), are newly recorded from Saba Island, Lesser Antilles, which also harbors one additional scolopendromorph and four more chilognath millipeds. Except for the plausibly native scolopendrid centipede, Scolopendra alternans Leach, 1813, all are human introductions. Concentrated sampling is needed in the cloud/elfin forest atop Mt. Scenery, where indigenous millipeds may reside, and with extraction techniques throughout the island, to potentially document the diplopod subclass Penicillata. Nine small Caribbean islands in addition to Saba have ...


Analysis Of Integrin Α6Β4 Function In Breast Carcinoma: A Dissertation, Kristin D. Gerson 2012 University of Massachusetts Medical School

Analysis Of Integrin Α6Β4 Function In Breast Carcinoma: A Dissertation, Kristin D. Gerson

GSBS Dissertations and Theses

The development and survival of multicellular organisms depends upon the ability of cells to move. Embryogenesis, immune surveillance, wound healing, and metastatic disease are all processes that necessitate effective cellular locomotion. Central to the process of cell motility is the family of integrins, transmembrane cell surface receptors that mediate stable adhesions between cells and their extracellular environment. Many human diseases are associated with aberrant integrin function. Carcinoma cells in particular can hijack integrins, harnessing their mechanical and signaling potential to propagate cell invasion and metastatic disease, one example being integrin α6β4. This integrin, often referred to simply as β4, is ...
