Diagnostic and prognostic value of cystatin C as an early marker of renal dysfunction in patients with cardiovascular pathology
|
Disorders of the kidneys often occur in cardiovascular diseases. They are connected with the heart by complex hemodynamic and neuroendocrine bonds. The structure, functions, and possibilities of using an endogenous indicator of the functional state of the kidney - cystatin C are discussed in the article. Available data allow the use of cystatin C as a predictor of renal dysfunction in patients with cardiovascular pathology and arterial hypertension, in particular. However, the widespread use of cystatin C in routine clinical practice requires further study and improvement.

Abstract Some unexpected promiscuous inhibitors were observed in a virtual screening protocol applied to select cruzain inhibitors from the ZINC database. Physical–chemical and pharmacophore model filters were used to reduce the database size. The selected compounds were docked into the cruzain active site. Six hit compounds were tested as inhibitors. Although the compounds were designed to be nucleophilically attacked by the catalytic cysteine of cruzain, three of them showed typical promiscuous behavior, revealing that false positives are a prevalent concern in VS programs.

The relationship between angiotensin-converting enzyme gene polymorphism and essential hypertension in Chongqing
|
Objective :To study the association of the angiotensin converting enzyme (ACE) insertion/deletion (I/D) polymorphism with essential hypertension in Chongqing. Methods:We use polymerase chain reaction (PCR) method to amplify sixteenth intron of ACE gene to analyse 114 healthy controls and 75 patients with essential hypertension. Polymorphism was characterized by three genotypes: homozygous alleles DD, II, and heterozygous alleles ID. Results:The frequency of homozygous alleles DD and the frequency of deletion alleles were significantly higher in the essential hypertension group than in the healthy controls (P0.005). Conclusion:The results indicate that a deletion polymorphism of ACE gene is associated with essential hypertension in Chongqing.

Thiazide diuretics (water pills) are medications that are used to treat high blood pressure (hypertension) and reduce fluid accumulation in the body. They work by reducing the ability of the kidneys to reabsorb salt and water from the urine and into the body thereby increasing the production and output of urine (diuresis).

The term oncology literally means a branch of science that deals with tumours and cancers. The word âoncoâ means bulk, mass, or tumor while â-logyâ means study. Each of the cells of the body have a tightly regulated system that controls their growth, maturity, reproduction and eventual death. Cancer begins when cells in a part of the body start to grow out of control. There are many kinds of cancer, but they all start because of out-of-control growth of abnormal cells.

A Study of Social Regulatory Mechanisms in Controlled Illicit Drug Users
|
An ongoing study of controlled marihuana, psychedelic, and opiate users shows that long-term, moderate illicit drug use is primarily supported by rituals and social sanctions. These guidelines for use, developed by segments of the drug subculture, militate against compulsive use. This work demonstrates the necessity of viewing quality of drug use as a function of sociocultural as well as pharmacological and psychological factors. Findings suggest that a system of social controls similar to that operating for alcohol use could be a more reasonable means of preventing compulsive use than the present prohibition of any and all illicit drug use.

We consider the following dynamic tax-rebate program. In each period, a (fixed) quantity tax is imposed on each unit of the good consumed and the tax revenue is rebated back to the consumer in the next period. The program lasts for infinite number of periods. We consider consumer's dynamic consumption behavior, the consumption behavior in the long-run steady state, and the welfare effects of the program. Under the standard continuity and strict convexity assumption on consumer preference, we show that the tax will strictly reduce the consumption of the good being taxed in each period as well as in the steady state, and consumer is strictly worse off. We also provide analytical solutions when consumer has quasilinear or Cobb-Douglas utility function.

This article presents findings from a qualitative study concerning drug injectors' constructs of human immunodeficiency virus (HIV) risk behavior. Analysis of data obtained from in-depth interviews (some with a vignette) of drug injectors found that when individuals needed an injection of drugs and were experiencing drug withdrawal they were more likely to take drug injecting risks. This was often discussed within an overall preoccupation with drug use. The substantive focus of the analysis goes on to explore drug injectors' desire to think about the consequences of HIV risk behavior at a later point in time. These exploratory findings highlight how further research needs to be undertaken in order to improve understanding of the temporal issues concerning drug injecting HIV risk behavior.

This resulted in increased per cent emergence and lower mean day of emergence of wheat plants. Per cent emergence (.v) was negatively correlated with penetrometer resistance (x). ::: ::: ::: ::: The increased germination was followed by greater plant growth, including increased plant height and yield. The Fe polycation treatments had no significant effect on root length measured at harvest.

The article examines the general affirmation that communication networks and mobility are important to science by examining how these factors played a relevant role in one specific case, that is, research on the embryology of certain species of armadillos in the early twentieth century. As we show, access to pregnant females of the species and transport time from the wild to the laboratory were significant issues in the early days of such research. The strategies used to obtain field samples, the temporality of certain phenomena, the commercial circuits of which the organisms under study were a part, and the transformations they underwent in the laboratory all afford a glimpse at some aspects of how these scientists approached their work and what problems they faced in producing new knowledge.

How and why more secure technologies succeed in legacy markets: Lessons from the success of SSH
|
SSH provided superior security while maintaining current functionality. SSH’s acceptance is demonstrated by the fact that installing SSH as an alternative to telnet is now widely considered to be a minimal security practice. The removal of telnet clients is now seen as a best practice [Fenzi, 2002], and this view has further increased the adoption of SSH.

The article examines the general affirmation that communication networks and mobility are important to science by examining how these factors played a relevant role in one specific case, that is, research on the embryology of certain species of armadillos in the early twentieth century. As we show, access to pregnant females of the species and transport time from the wild to the laboratory were significant issues in the early days of such research. The strategies used to obtain field samples, the temporality of certain phenomena, the commercial circuits of which the organisms under study were a part, and the transformations they underwent in the laboratory all afford a glimpse at some aspects of how these scientists approached their work and what problems they faced in producing new knowledge.

Semiconductor technology and the changing world of computing

The rapid development of the microprocessor has overshadowed developments in minicomputer and mainframe computer technology, and some commentators have forecast the eclipse of these older types of computer. However, significant developments are taking place in mini and mainframe computers, and an analysis of the needs of the three fundamental approaches to the use of computers suggests that there will always be a need for the three very different types of computer.

What species did Darwin study for dispersal across oceans>
|
Darwin's barnacle studies convinced him that variation arose constantly and not just in response to changed circumstances. In 1854, he completed the last part of his Beagle-related writing and began working full-time on evolution. His thinking changed from the view that species formed in isolated populations only, as on islands, to an emphasis on speciation without isolation; that is, he saw increasing specialisation within large stable populations as continuously exploiting new ecological niches. He conducted empirical research focusing on difficulties with his theory. He studied the developmental and anatomical differences between different breeds of many domestic animals, became actively involved in fancy pigeon breeding, and experimented (with the help of his son Francis) on ways that plant seeds and animals might disperse across oceans to colonise distant islands. By 1856, his theory was much more sophisticated, with a mass of supporting evidence.

According to Mendelian inheritance, variations in an organism's phenotype (observable physical and behavioral characteristics) are due in part to variations in its genotype (particular set of genes). Each gene specifies a particular trait with different sequence of a gene (alleles) giving rise to different phenotypes. Most eukaryotic organisms (such as the pea plants Mendel worked on) have two alleles for each trait, one inherited from each parent.:20

How many millions of years ago had Homo erectus spread throughout Europa and Asia?
|
Today, all humans are classified as belonging to the species Homo sapiens and sub-species Homo sapiens sapiens. However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, are theorized to have evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time. Homo erectus is theorized to have evolved more than 1.8 million years ago, and by 1.5 million years ago had spread throughout Europe and Asia. Virtually all physical anthropologists agree that Archaic Homo sapiens (A group including the possible species H. heidelbergensis, H. rhodesiensis and H. neanderthalensis) evolved out of African Homo erectus ((sensu lato) or Homo ergaster).

Darwin and Wallace unveiled evolution in the late 1850s. There was an immediate rush to bring it into the social sciences. Paul Broca in Paris was in the process of breaking away from the Société de biologie to form the first of the explicitly anthropological societies, the Société d'Anthropologie de Paris, meeting for the first time in Paris in 1859.[n 4] When he read Darwin he became an immediate convert to Transformisme, as the French called evolutionism. His definition now became "the study of the human group, considered as a whole, in its details, and in relation to the rest of nature".

what is the heterotroph hypothesis

The Heterotroph Hypothesis is the proposal that the first living organism was a HETEROTROPH. Before there were other organisms, they would feed on surrounding âleft-oversâ of their origin. There is evidence that the pre-life atmosphere and water environment was a reducing one, (no oxygen).

Heterozygosityâthe condition of having two different alleles at a locusâis fundamental to the study of genetic variation in populations. Indeed, Mendelâs original work was based on tracing the transmission to progeny of the two alleles present in heterozygous individuals at individual loci or combinations of loci.

which theory says that populations change slowly over time?
|
Evolution is a scientific theory used by biologists. It explains how living things change over a long time, and how they have come to be the way they are. Earth is very old. By studying the layers of rock that make up Earth's crust, we can find out about its past. This kind of research is called historical geology.
|
Population Evolution Smallest Unit of Evolution One misconception is that organisms evolve during their lifetimes. Natural selection acts on individuals, but only populations evolve. Consider, for example, a population of medium ground finches on Daphne Major Island; Microevolution is a change in allele frequencies in a population over generations.

What did sociology in science explain?
|
Much of the study of the history of science has been devoted to answering questions about what science is, how it functions, and whether it exhibits large-scale patterns and trends. The sociology of science in particular has focused on the ways in which scientists work, looking closely at the ways in which they "produce" and "construct" scientific knowledge. Since the 1960s, a common trend in science studies (the study of the sociology and history of science) has been to emphasize the "human component" of scientific knowledge, and to de-emphasize the view that scientific data are self-evident, value-free, and context-free. The field of Science and Technology Studies, an area that overlaps and often informs historical studies of science, focuses on the social context of science in both contemporary and historical periods.

Hunter-gatherer societies manifest significant variability, depending on climate zone/life zone, available technology and societal structure. Archaeologists examine hunter-gatherer tool kits to measure variability across different groups. Collard et al. (2005) found temperature to be the only statistically significant factor to impact hunter-gatherer tool kits. Using temperature as a proxy for risk, Collard et al.'s results suggest that environments with extreme temperatures pose a threat to hunter-gatherer systems significant enough to warrant increased variability of tools. These results support Torrence's (1989) theory that risk of failure is indeed the most important factor in determining the structure of hunter-gatherer toolkits.

Who was thought to be the original believer of humanism in of the Renaissance period?
|
Renaissance humanism was an intellectual movement in Europe of the later Middle Ages and the Early Modern period. The 19th-century German historian Georg Voigt (1827–91) identified Petrarch as the first Renaissance humanist. Paul Johnson agrees that Petrarch was "the first to put into words the notion that the centuries between the fall of Rome and the present had been the age of Darkness". According to Petrarch, what was needed to remedy this situation was the careful study and imitation of the great classical authors. For Petrarch and Boccaccio, the greatest master was Cicero, whose prose became the model for both learned (Latin) and vernacular (Italian) prose.
|
In later editions of the book, Darwin traced evolutionary ideas as far back as Aristotle; the text he cites is a summary by Aristotle of the ideas of the earlier Greek philosopher Empedocles. Early Christian Church Fathers and Medieval European scholars interpreted the Genesis creation narrative allegorically rather than as a literal historical account; organisms were described by their mythological and heraldic significance as well as by their physical form. Nature was widely believed to be unstable and capricious, with monstrous births from union between species, and spontaneous generation of life.

The study in which ecologists examine the way predators interact with their prey is called what?
|
Classification of predators by the extent to which they feed on and interact with their prey is one way ecologists may wish to categorize the different types of predation. Instead of focusing on what they eat, this system classifies predators by the way in which they eat, and the general nature of the interaction between predator and prey species. Two factors are considered here: How close the predator and prey are (in the latter two cases the term prey may be replaced with host) and whether or not the prey are directly murdered by the predator is considered, with true predation and parasitoidism involving certain death.

Waitz was influential among the British ethnologists. In 1863 the explorer Richard Francis Burton and the speech therapist James Hunt broke away from the Ethnological Society of London to form the Anthropological Society of London, which henceforward would follow the path of the new anthropology rather than just ethnology. It was the 2nd society dedicated to general anthropology in existence. Representatives from the French Société were present, though not Broca. In his keynote address, printed in the first volume of its new publication, The Anthropological Review, Hunt stressed the work of Waitz, adopting his definitions as a standard.[n 5] Among the first associates were the young Edward Burnett Tylor, inventor of cultural anthropology, and his brother Alfred Tylor, a geologist. Previously Edward had referred to himself as an ethnologist; subsequently, an anthropologist.

What is evolutionary anthropology based in?
|
Evolutionary anthropology is the interdisciplinary study of the evolution of human physiology and human behaviour and the relation between hominins and non-hominin primates. Evolutionary anthropology is based in natural science and social science, combining the human development with socioeconomic factors. Evolutionary anthropology is concerned with both biological and cultural evolution of humans, past and present. It is based on a scientific approach, and brings together fields such as archaeology, behavioral ecology, psychology, primatology, and genetics. It is a dynamic and interdisciplinary field, drawing on many lines of evidence to understand the human experience, past and present.

Hume and other Scottish Enlightenment thinkers developed a 'science of man', which was expressed historically in works by authors including James Burnett, Adam Ferguson, John Millar, and William Robertson, all of whom merged a scientific study of how humans behaved in ancient and primitive cultures with a strong awareness of the determining forces of modernity. Modern sociology largely originated from this movement, and Hume's philosophical concepts that directly influenced James Madison (and thus the U.S. Constitution) and as popularised by Dugald Stewart, would be the basis of classical liberalism.

What was a way that theologians compromised with the information in Darwin's book?
|
Baden Powell praised "Mr Darwin's masterly volume [supporting] the grand principle of the self-evolving powers of nature". In America, Asa Gray argued that evolution is the secondary effect, or modus operandi, of the first cause, design, and published a pamphlet defending the book in terms of theistic evolution, Natural Selection is not inconsistent with Natural Theology. Theistic evolution became a popular compromise, and St. George Jackson Mivart was among those accepting evolution but attacking Darwin's naturalistic mechanism. Eventually it was realised that supernatural intervention could not be a scientific explanation, and naturalistic mechanisms such as neo-Lamarckism were favoured over natural selection as being more compatible with purpose.

Over the years, various attempts have been made to synthesize a single Buddhist text that can encompass all of the major principles of Buddhism.

The use of Sino-Brazilian satellite images to study small cities of the Brazilian Amazon Region is also discussed. A HCR image was used to classify the image of the study area into four classes: urban, forest, clouds, and shadows, by visual interpretation. This map was compared with another map produced with unsupervised classification. A confusion matrix was produced to evaluate the accuracy of unsupervised classification. Comparison between the reference map (visual interpretation) and the unsupervised classification map verified that 82.8% of the areas were classified correctly. This ability to recognize and delimitate small cities in Amazonia demonstrates the quality of the CBERS – HCR image.

Comparison of surface layer properties of composite resins by ESCA, SEM and X-ray cliffractometry

Abstract Hyperfine surface layer properties of three types of dental composite resins, highly-filled, conventional, and micro-filled resins, were studied using X-ray photoelectron spectroscopy (ESCA) by a combination of X-ray diffractometry and scanning electron microscopy (SEM). X-ray diffraction and SEM analysis showed clearly that each resin has different characteristics of SiO 2 particle size and distribution. ESCA depth resolution with argon ion etching indicated that in contrast to conventional and microfilled resins, carbon due to polymers of highly-filled resin decreases dramatically with increasing depth in the nanometer range of the resin-rich surface layer.

The Role of Credit in Predicting US Recessions
|
We study the role of credit in forecasting US recession periods with probit models. We employ both classical recession predictors and common factors based on a large panel of financial and macroeconomic variables as control variables. Our findings suggest that a number of credit variables are useful predictors of US recessions over and above the control variables both in and out of sample. Especially the excess bond premium, capturing the cyclical changes in the relationship between default risk and credit spreads, is found to be a powerful predictor. Overall, models that combine credit variables, common factors, and classic recession predictors, are found to have the best forecasting performance.

SDS-PAGE was used for establishing the genetic identity of sunflower hybrids and determining percentage genetic purity of F 1 hybrid seeds. The hybrids differed from each other in terms of the total number of protein bands, protein bands in three zones, thickness and intensity of protein bands; and likewise the aberrant were detected within a hybrid. The relative mobility of each protein band, Rm value, provided a basis to distinguish aberrant types within an F 1 hybrid. The hybrids studied differed in both specific and common Rm values, presumably due to the differences in helianthinins in the hybrids. SDS-PAGE and field grow-out test gave largely similar results. The possible use of SDS-PAGE technique in routine testing for determination of percentage genetic purity of sunflower hybrid seed lots for commerce is discussed.

Construction of a Molecular Linkage Map and QTL Analysis of Fertility Restorer of Capsicum annuum L.
|
In this study, a doubled-haploid population with 115 individuals derived from a cross of Yolo wonder×Perennial were test-crossed by 77013A, a stable germ male sterile line, to construct a genetic map and locate QTLs of fertility restorer. Three methods were adopted to investigate the fertility of each line of the tested population. Among 128 AFLP primers pairs, 61 amplified polymorphisms between two parents were found. The map, as the results, included 8 linkage groups and 43 markers. Based on the investigation of fertility of the tested population, 4 main QTLs were located on linkage group 1,3,6,8, respectively.

A genome analysis of endoreplication in the Drosophila ovary.
|
Gene amplification is used by follicle cells to increase the copy number of Drosophila chorion genes, which encode structural components of the eggshell. A new study by Claycomb et al. in this issue of Developmental Cell raises the possibility that gene amplification might also be used for the developmental patterning of the egg chamber and oocyte.

Summary Clonal propagation or apomixis is common in the plant kingdom. Among trees, agamospermy and vegetative propagation are relatively rare in nature. In this paper the roles of different modes of propagation in the survival strategy of three different plant groups are discussed. Conclusions for tree breeding strategies are drawn: clones have an important role to play. Greatest genetic gain and flexibility are attained when both sexual and clonal propagation occur. Genetic diversity should be maintained in any strategy.

Gene Effects for Grain Yield and its Component Characters in Rice (Oryza Sativa L.)
|
Five generations (P1, P2, F1, F2 and F3) of six rice crosses were grown in a randomised block design for estimating the nature and magnitude of gene effects for grain yield and its component characters. The scaling tests indicated that the scales ‘C’ and ‘D’ were significant for all the six characters in all the crosses studied. Gene effects were found to be cross specific. The results indicated the importance of duplicate dominant epistasis for number of productive tillers, number of filled grains and 100 grain weight. For biomass, grain yield and harvest index complementary recessive epistasis was found to be important.

The need for an extracellular component for cell pairing in Tetrahymena.
|
Abstract Cell pairing in Tetrahymena takes place among cells that have undergone a prepairing interaction, co-stimulation. Pairing does not take place if co-stimulated cells are washed free of their conditioned medium, but washed co-stimulated cells will pair if restored to either co-stimulation conditioned medium or starvation conditioned medium. This demonstrates a need for an extracellular factor in the pairing reaction.

summary ::: Populations of diploid and autotetraploid Anthoxanthum alpinum A. & D. Love formed a narrow hybrid zone in a study area in the Swiss Prealps. Detailed vegetation analyses were performed along transects in several contact zones between the two cytotypes. The vegetation differed according to the position in the hybrid zone. When considering the hybrid zone as a whole, and for one transect that was analysed in detail, there was strong evidence for habitat segregation between the cytotypes. Vegetation transitions, habitat preference and segregation of the two cytotypes differed according to location in the hybrid zone. The origin and dynamics of the hybrid zone are discussed.

EVOLUTION IN OPUNTIA (CACTACEAE)
|
The hypothesized natural interspecific hybrid origin of two cacti, Opuntia Xrooneyi and O. Xspinosibacca, has been investigated by a variety of non-molecular based techniques. Herein I explore DNA sequence and random amplified polymorphic DNA (RAPD) banding pattern data as it relates to these two cases of putative hybridization. Traditional parsimony-based analyses of nuclear ribosomal and chloroplast DNA sequences do not resolve the phylogenetic position of these two species among closelyrelated taxa, but a median network analysis is presented that yields an approach to interpreting these relationships. Finally, an analysis of RAPD banding pattern data provides evidence of the additive genetic pattern expected for these two interspecific hybrids. These results support the inferences of non-molecular based studies.

What is the main grouping of a plant know as?
|
Kingdom Plantae belongs to Domain Eukarya and is broken down recursively until each species is separately classified. The order is: Kingdom; Phylum (or Division); Class; Order; Family; Genus (plural genera); Species. The scientific name of a plant represents its genus and its species within the genus, resulting in a single world-wide name for each organism. For example, the tiger lily is Lilium columbianum. Lilium is the genus, and columbianum the specific epithet. The combination is the name of the species. When writing the scientific name of an organism, it is proper to capitalise the first letter in the genus and put all of the specific epithet in lowercase. Additionally, the entire term is ordinarily italicised (or underlined when italics are not available).

Physician Valerius Cordus (1515–1544) authored a botanically and pharmacologically important herbal Historia Plantarum in 1544 and a pharmacopoeia of lasting importance, the Dispensatorium in 1546. Naturalist Conrad von Gesner (1516–1565) and herbalist John Gerard (1545–c. 1611) published herbals covering the medicinal uses of plants. Naturalist Ulisse Aldrovandi (1522–1605) was considered the father of natural history, which included the study of plants. In 1665, using an early microscope, Polymath Robert Hooke discovered cells, a term he coined, in cork, and a short time later in living plant tissue.

Identification of cultivars and hybrids in Syringa and Cucurbita by DNA fingerprinting.
|
We have tested the applicability of AFLP analysis in varietal identification in Syringa and parentage identification after hybrid breeding in Cucurbita in a practical micropropagation situation. Both in Syringa as well as in Cucurbita, AFLP fingerprints were highly reproducible and produced similar band patterns irrespective of the starting material being either tissue culture-derived or greenhouse material. A single primer combination yielded enough polymorphic bands to unequivocally discriminate among 13 closely related lilac cultivars. Following hybrid production after wide crosses between Cucurbita pepo x C. maxima lines AFLP fingerprints clearly identified the parental genomes in regenerating hybrid plants and could be used to discriminate between true hybrids and gynogenic haploids or spontaneous diploids.

Bacterial leaf spot of peach caused by Xanthomonas arboricola pv. pruni in China
|
AbstractLeaf spot diseases occur widely and pose serious impacts on peach production in China. In this study, 60 symptomatic leaf samples were collected from seven provinces in China. Diseased samples were plated on nutrient agar and sucrose-peptone-agar media and purified colonies were identified as Xanthomonas arboricola pv. pruni (Xap) based on morphological features, molecular identification and pathogenicity test. Hypersensitive response and pathogenicity tests were conducted on inoculated tobacco and peach seedlings. Phylogenetic analysis of 16S rRNA gene sequences indicated that the Xap isolates clustered together with Korean, Japan and Taiwan isolates. This is the first report of bacterial leaf spot caused by Xap on peach in China.

Influence of Multi-Gene Allele Combinations on Grain Size of Rice and Development of a Regression Equation Model to Predict Grain Parameters
|
Background ::: Grain size is one of the key factors determining yield and quality in rice. A large number of genes are involved in the regulation of grain size parameters such as grain length and grain width. Different alleles of these genes have different impacts on the grain size traits under their control. However, the combined influence of multiple alleles of different genes on grain size remains to be investigated. Six key genes known to influence grain size were investigated in this study: GS3, GS5, GS6, GW2, qSW5/GW5, and GW8/OsSPL16. Allele and grain measurement data were used to develop a regression equation model that can be used for molecular breeding of rice with desired grain characteristics.

Morphological Variation, Growth, and Yield of Tomato Plants Vegetatively Propagated by the Complete Decapitation Method
|
AbstractThe complete decapitation method (CDM), a new mass propagation technique in which adventitious shoots are regenerated from cut tomato (Solanum lycopersicum L.) stems, may induce variations similar to those observed in tissue culture. Morphological defect occurrence, growth, and fruit yield of CDM-regenerated clones were compared with those of plants produced from seed. Morphological defect frequencies of seedlings and clones were 3.5% and 6.0%, respectively. Leaf position of first fruit trusses was lower in clones than in seedlings; flower number, fruit set, and yield on first to third trusses were similar between clones and seedlings. The CDM-propagated vegetative clones are suitable for tomato nursery production.

Background ::: Spontaneously metastatic xenograft models of cancer are infrequent and the few that exist are resource intensive. In xenografts, caliper measurements can be used to determine primary tumor burden and response to therapy but in metastatic disease models determination of the presence of metastatic disease, metastatic burden, and response to therapy are difficult, often requiring serial necropsy. In this study we characterized the development of visceral metastases in a patient derived xenograft model (PDXM) using in vivo imaging.

Ovipositional preference of the cotton fleahopper, Pseudatomoscelis seriatus, and distribution of eggs among host plant species
|
Distribution of eggs of cotton fleahopper, Pseudatomoscelis seriatus among wild host plants in a field study area was found to be related to the species and phenology of the plants. On a per plant basis, horsemint, Monarda punctata , accounted for the highest proportion of eggs until mid-July. After July 29 all P. seriatus eggs in the study area were found on Croton capitatus . Other aspects of the distribution of eggs among host plants in the field were investigated. Laboratory studies showed that flowering Monarda punctata , and flowering Croton capitatus were favored over other host species and other phenological stages as oviposition sites. Significantly more eggs were deposited in a pubescent cotton variety than in a glabrous variety.

Summary ::: ::: The addition of 0.07 per cent Fe or more in the form of polycations decreased the total area of cracks and increased the number of transmissive pores of soils after simulated rainfall and drying. This resulted in increased per cent emergence and lower mean day of emergence of wheat plants. Per cent emergence (.v) was negatively correlated with penetrometer resistance (x). ::: ::: ::: ::: The increased germination was followed by greater plant growth, including increased plant height and yield. The Fe polycation treatments had no significant effect on root length measured at harvest.
