The Empire Of Cancer: Gene Patents And Cancer Voices, Matthew Rimmer Dec 2013

The Empire Of Cancer: Gene Patents And Cancer Voices, Matthew Rimmer

Matthew Rimmer

In his book, The Emperor of All Maladies, Siddhartha Mukherjee writes a history of cancer — ‘It is a chronicle of an ancient disease — once a clandestine, “whispered-about” illness — that has metamorphosed into a lethal shape-shifting entity imbued with such penetrating metaphorical, medical, scientific, and political potency that cancer is often described as the defining plague of our generation’.Increasingly, an important theme in the history of cancer is the role of law, particularly in the field of intellectual property law. It is striking that a number of contemporary policy debates over intellectual property and public health have concerned cancer research ...

Jeffrey Willardson

This study compared two different rest intervals (RI) between sets of resistance exercise. Ten resistance-trained men (M age = 24.3, SD = 3.5 yr.; M weigh t= 80.0 kg, SD = 15.3; M height = 1.75 m, SD = 0.04) performed five sets of Smith machine bench presses at 60% of one repetition maximum, either with 1.5 min. or 3 min. RI between sets. Their repetition performance, total training volume, velocity, fatigue, rating of perceived exertion, and muscular power were measured. All of these measures indicated that performance was significantly better and fatigue was significantly lower in the ...


Differential Habitat Use By Common Watersnakes (Nerodia Sipedon), Lorin A. Neuman-Lee, Andrew M. Durso, Nicholas M. Kiriazis, Melanie J. Olds, Stephen J. Mullin Dec 2013

Differential Habitat Use By Common Watersnakes (Nerodia Sipedon), Lorin A. Neuman-Lee, Andrew M. Durso, Nicholas M. Kiriazis, Melanie J. Olds, Stephen J. Mullin

Stephen J. Mullin

Understanding intraspecific variation in habitat use is important for the management of any species. In many studies of reptiles, habitat use by juveniles is poorly understood when compared to their adult conspecifics because of capture biases and logistical constraints. We compared habitat use between sexes and age classes of Common Watersnakes (Nerodia sipedon) at a reservoir in central Illinois. Juvenile N. sipedon occurred more frequently in habitat with high canopy cover, whereas adult N. sipedon, especially reproductive females, were found exclusively in habitat with no canopy cover. Adult males used both locations equally. We emphasize the need to investigate ontogenetic ...


Ultra-Deep Pyrosequencing Of Partial Surface Protein Genes From Infectious Salmon Anaemia Virus (Isav) Suggest Novel Mechanisms Involved In Transition To Virulence, Torstein Tengs Dr. Nov 2013

Ultra-Deep Pyrosequencing Of Partial Surface Protein Genes From Infectious Salmon Anaemia Virus (Isav) Suggest Novel Mechanisms Involved In Transition To Virulence, Torstein Tengs Dr.

Dr. Torstein Tengs

Uncultivable HPR0 strains of infectious salmon anaemia viruses (ISAVs) infecting gills are non-virulent putative precursors of virulent ISAVs (vISAVs) causing systemic disease in farmed Atlantic salmon (Salmo salar). The transition to virulence involves two molecular events, a deletion in the highly polymorphic region (HPR) of the hemagglutinin-esterase (HE) gene and a Q266→L266 substitution or insertion next to the putative cleavage site (R267) in the fusion protein (F). We have performed ultra-deep pyrosequencing (UDPS) of these gene regions from healthy fish positive for HPR0 virus carrying full-length HPR sampled in a screening program, and a vISAV strain from an ISA ...

Monohybrid Mendelian Segregation In An Interspecific Hybrid Population Of Tetraploid X Diploid Coffea Species- Part 2, Anil Kumar, Subbugan Ganesh, Central Coffee Research Institute

Emily Scott

Coffee possesses normal sexual propagation behaviour and exhibits various characters in a large population. The work on the extent of variation is very limited and not well understood. In this context a study was undertaken during 2008-2011 to study the monohybrid segregation pattern in F2 population of C. arabica cv. ‘Cauvery’x (C. congensis x C. canephora var. robusta) established at Coffee Research Sub Station, Chettalli, Kodagu District, Karnataka in the year 2002. The results revealed that coffee varieties grown under Indian conditions possessed dependent and independent characters. The dependent characters followed the independent assortment along with closely associated characters ...


Zebrafish: An In Vivo Model For The Study Of Human Diseases, Bibhas Kar, Sivamani Subbiah Nov 2013

Zebrafish: An In Vivo Model For The Study Of Human Diseases, Bibhas Kar, Sivamani Subbiah

Emily Scott

The zebrafish (Danio rerio) is a powerful model organism for the study of vertebrate biology, being well suited to both developmental and genetic analysis. More recently, the rapid progress of various zebrafish genomics infrastructure initiatives is facilitating the development of zebrafish models of human disease. Genome organization and the pathways involved into control of signal transduction appear to be highly conserved between zebrafish and humans and therefore zebrafish may be used for modeling of human diseases. This review will highlight and describe the utility of zebrafish in the study of human diseases.


Water Stress Strengthens Mutualism Among Ants, Trees, And Scale Insects, Elizabeth G. Pringle, Erol Akc¸Ay, Ted K. Raab, Rodolfo Dirzo, Deborah M. Gordon Nov 2013

Water Stress Strengthens Mutualism Among Ants, Trees, And Scale Insects, Elizabeth G. Pringle, Erol Akc¸Ay, Ted K. Raab, Rodolfo Dirzo, Deborah M. Gordon

Ted K. Raab

Abiotic environmental variables strongly affect the outcomes of species interactions. For example, mutualistic interactions between species are often stronger when resources are limited. The effect might be indirect: water stress on plants can lead to carbon stress, which could alter carbon-mediated plant mutualisms. In mutualistic ant–plant symbioses, plants host ant colonies that defend them against herbivores. Here we show that the partners’ investments in a widespread ant–plant symbiosis increase with water stress across 26 sites along a Mesoamerican precipitation gradient. At lower precipitation levels, Cordia alliodora trees invest more carbon in Azteca ants via phloem-feeding scale insects that ...

Rajesh Pati

Mango (Mangifera indica L.) is the most important fruit crop of the world. India ranks first among world’s mango producing countries accounting for 57.18 % of the total world mango production of 19.22 million tones. With the development of rDNA technology, plant breeders have access to a large number of genes that can be integrated into the plant genome.


Histological And Biochemical Changes In Aegle Marmelos, Rajesh Pati Oct 2013

Histological And Biochemical Changes In Aegle Marmelos, Rajesh Pati

Rajesh Pati

Aegle marmelos Corr., belongs to family Rutaceae, is more prized for its pharmacological virtues than its edible quality. Because of pharmacological importance, it’s become potential candidate for developing transgenics to enhance its medicinal properties. Maximum mortality of micropropagated plants occur during acclimatization phase because plantlets undergo rapid and extreme changes in physiological functioning, histological and biochemical changes. In order to investigate the actual reason of this limitation, test samples were collected at different stages of micropropagation of Aegle marmelos Corr. (In vitro stage, acclimation stage, and field established plants).

Somatic Embryogenesis In Mono And Poly Embryonic Cultivars, Rajesh Pati

Rajesh Pati

A standard uniform protocol of regeneration is the prime and foremost prerequisite for not only improve the productivity, the production from the existing area but also development of transgenics in mango for various traits. Polyembryonic cultivars are good rootstock because of moderate canopy, tolerant to draught, salt, environmental stress (wind, high temperature, air pollution), fungal disease (anthracnose, powdery mildew, gummosis) and hoppers.

Genetic Transformation Of Bael (Aegle Marmelos Corr.), Rajesh Pati

Rajesh Pati

Aegle marmelos Corr. is better known for its medicinal values rather than its edible quality. Every part of the plant viz. leaves, fruits, roots, and the bark are used for treating various diseases related to heart, stomach, bacterial, fungal, viral, worms, fertility, fever and cosmetics. Marmelosin is one of the major compounds (coumarin), used to treat various diseases. Till date, there are no varieties developed for commercial orchards of Bael and hence, regarded as one among the underutilized fruits of India. Therefore, there is an urgent need for breeding new and cultivable varieties in Aegle marmelos. But the problem for ...

Micropropagation In Fruit Crops, Rajesh Pati

Rajesh Pati

Micropropagation is a proven means of producing millions of identical plants under a controlled and aseptic condition, independent of seasonal constraints. It not only provides economy of time and space but also gives greater output and allows further augmentation of elite disease free propagules. India is homeland of many important fruit crops such as Indian gooseberry (Emblica officinalis Gaertn), bael (Aegle marmelos Corr.), Guava (, Psidium guajava), jamun or black plum (Syzygium cuminii L. Skeels.), Mango (Mangifera indica) and Papaya (Carica papaya).

Effects Of Deterioration Parameters On Storage Of Maize: A Review, Rashid A. Suleiman Sep 2013

Effects Of Deterioration Parameters On Storage Of Maize: A Review, Rashid A. Suleiman

RASHID A SULEIMAN

Maize (Zea mays L), commonly known as corn in the United States, is the third most important cereal grain worldwide, after wheat and rice. It is a basic staple grain for large groups of people in Africa, Latin America, and Asia. In tropical countries, a large proportion of the maize is harvested and stored under humid and warm climatic conditions, which subsequently results in rapid deterioration of the grains, mainly because of growth of molds and pests. This study reviewed the main factors that lead to deterioration of maize in tropical countries and suggests ways of preventing the identified causes ...

Sequence Analysis Of The Genome Of Piscine Orthoreovirus (Prv) Associated With Heart And Skeletal Muscle Inflammation (Hsmi) In Atlantic Salmon (Salmo Salar), Torstein Tengs Dr. Jul 2013

Sequence Analysis Of The Genome Of Piscine Orthoreovirus (Prv) Associated With Heart And Skeletal Muscle Inflammation (Hsmi) In Atlantic Salmon (Salmo Salar), Torstein Tengs Dr.

Dr. Torstein Tengs

Piscine orthoreovirus (PRV) is associated with heart- and skeletal muscle inflammation (HSMI) of farmed Atlantic salmon (Salmo salar). We have performed detailed sequence analysis of the PRV genome with focus on putative encoded proteins, compared with prototype strains from mammalian (MRV T3D)- and avian orthoreoviruses (ARV-138), and aquareovirus (GCRV-873). Amino acid identities were low for most gene segments but detailed sequence analysis showed that many protein motifs or key amino acid residues known to be central to protein function are conserved for most PRV proteins. For M-class proteins this included a proline residue in μ2 which, for MRV, has been ...
