Skeletal Muscle Myofilament Adaptations To Aging, Disease And Disuse And Their Effects On Whole Muscle Performance In Older Adult Humans, Mark S. Miller, Damien M. Callahan, Michael J. Toth
Skeletal Muscle Myofilament Adaptations To Aging, Disease And Disuse And Their Effects On Whole Muscle Performance In Older Adult Humans, Mark S. Miller, Damien M. Callahan, Michael J. Toth
Mark S. Miller
Skeletal muscle contractile function declines with aging, disease, and disuse. In vivo muscle contractile function depends on a variety of factors, but force, contractile velocity and power generating capacity ultimately derive from the summed contribution of single muscle fibers. The contractile performance of these fibers are, in turn, dependent upon the isoform and function of myofilament proteins they express, with myosin protein expression and its mechanical and kinetic characteristics playing a predominant role. Alterations in myofilament protein biology, therefore, may contribute to the development of functional limitations and disability in these conditions. Recent studies suggest that these conditions are associated …

Elite Female Tae Kwon Do Athletes Have Faster Reaction Time And Longer Movement Time Than Males During A Striking Kick, Ulysses Fernandes Ervilha, Valmar Fernandes Da Silva, Rubens Correa Araújo, Luis Mochizuki, Joseph Hamill
Elite Female Tae Kwon Do Athletes Have Faster Reaction Time And Longer Movement Time Than Males During A Striking Kick, Ulysses Fernandes Ervilha, Valmar Fernandes Da Silva, Rubens Correa Araújo, Luis Mochizuki, Joseph Hamill
Joseph Hamill
Background & Study Aim: An important aspect of ap bal ap dolio tchagui kick in tae kwon do is that it is usually performed in reaction to a signal or event. That is, given a specific stimulus (i.e. the movement of the opponent), the tae kwon do athlete must react as quickly and accurately as possible to the stimulus. Reacting to a stimulus requires preparation and it is essential to determine this preparation of an elite athlete to perform a task. Therefore, to investigate this movement a reaction time paradigm is appropriate wherein the athlete accomplishes the kick in response …

Acute Effect Of Different Minimalist Shoes On Foot Strike Pattern And Kinematics In Rearfoot Strikers During Running, Roberto Squadrone, Renato Rodano, Joseph Hamill, Ezio Preatoni
Joseph Hamill
Despite the growing interest in minimalist shoes, no studies have compared the efficacy of different types of minimalist shoe models in reproducing barefoot running patterns and in eliciting biomechanical changes that make them differ from standard cushioned running shoes. The aim of this study was to investigate the acute effects of different footwear models, marketed as “minimalist” by their manufacturer, on running biomechanics. Six running shoes marketed as barefoot/minimalist models, a standard cushioned shoe and the barefoot condition were tested. Foot–/shoe–ground pressure and three-dimensional lower limb kinematics were measured in experienced rearfoot strike runners while they were running at 3.33 …

Insect Visitation Of Peduncular And Petiolar Extrafloral Nectar Glands On Castor Bean (Ricinus Communis L.) Plants In Southern California, Victor D. Carmona
Insect Visitation Of Peduncular And Petiolar Extrafloral Nectar Glands On Castor Bean (Ricinus Communis L.) Plants In Southern California, Victor D. Carmona
Victor D. Carmona-Galindo
Castor bean (Ricinus communis L.) is a myrmecophytic plant species with specialized extrafloral nectar (EFN) glands that serve to attract predatory insects, which in return defend plant-tissues against herbivores. The EFN glands on castor bean plants are located along the leaf petioles as well as on the peduncles of its imperfect (unisexual) flowers. This field-project evaluates the richness, diversity, and species assemblage of insects visiting EFN glands located on (female and male) flower peduncles and leaf petioles on castor bean plants growing in a Southern California coastal landscape. We detected that EFN glands on female-flower peduncles were visited by an …

Environmental Sustainability Criteria In The Coffee Sector – Lessons That Can Be Learnt, Evgenia Pavlovskaia
Evgenia Pavlovskaia
In the article, the issue of environmental sustainability criteria in the coffee sector is researched. Such important aspects in this topic are highlighted and discussed as reasons for the emergence of sustainability criteria for coffee and factors that make the production of coffee sustainable. Two widely used sustainability standards for coffee, the Fair Trade Coffee sustainability standard and the Utz Certified Coffee sustainability standard, are investigated more precisely. The environmental requirements of these standards in the form of environmental sustainability criteria, and mechanisms to control their fulfilment are outlined. The issue of control is separately highlighted, because it is considered …

Introduction To Genome Browsers, Rolando Garcia-Milian
Rolando Garcia-Milian
In this workshop we will learn how to navigate the genome browsers from NCBI's Genome Workbench, UCSC Genome Browser, and Ensembl. These browsers are valuable tools when identifying, localizing genes, and looking at their information in the genomic context. By using concrete examples, it will be shown how to locate a human gene, download a gene sequence and its upstream sequence, locate Single Nucleotide Polymorphisms (SNPs) and conserved regions, and use the browsers to download results in a batch.

Visualization Of Temporal Change In Soundscape Power Of A Michigan Lake Habitat Over A 4-Year Period, Stuart H. Gage, Anne C. Axel
Anne C. Axel
Soundscape Ecology is an emerging area of science that does not focus on the identification of species in the soundscape but attempts to characterize sounds by organizing them into those produced by biological organisms such as birds, amphibians, insects or mammals; physical environmental factors such as thunder, rainfall or wind; and sounds produced by human entities such as airplanes, automobiles or air conditioners. The soundscape changes throughout the day and throughout the seasons. The soundscape components that create the sound occur at different frequencies. A set of metrics termed soundscape power was computed and visualized to examine the patterns of …

Patty S. Freedson
Purpose Gathering contextual information (i.e., location and purpose) about active and sedentary behaviors is an advantage of self-report tools such as previous day recalls (PDR). However, the validity of PDR’s for measuring context has not been empirically tested. The purpose of this paper was to compare PDR estimates of location and purpose to direct observation (DO). Methods Fifteen adult (18–75 y) and 15 adolescent (12–17 y) participants were directly observed during at least one segment of the day (i.e., morning, afternoon or evening). Participants completed their normal daily routine while trained observers recorded the location (i.e., home, community, work/school), purpose …

Can They Dig It? Functional Morphology And Degrees Of Semifossoriality Among Some American Shrews (Mammalia, Soricidae)., Neal Woodman, Sarah A. Gaffney
Neal Woodman
Small-eared shrews (Mammalia: Soricidae: Cryptotis), exhibit modifications of the forelimb skeleton that have been interpreted as adaptations for semifossoriality. Most species inhabit remote regions, however, and their locomotory and foraging behaviors remain mostly speculative. To better understand the morphological modifications in the absence of direct observations, we quantified variation in these species by measuring 151 individuals representing 18 species and populations of Cryptotis and two species of moles (Talpidae) for comparison. From our measurements, we calculated 22 indices, most of which have been used previously to characterize substrate use among rodents and other taxa. We analyzed the indices using 1) …
