UNLABELLED PREMISE OF THE STUDY Nuclear microsatellite markers were developed for Lobelia inflata (Campanulaceae), an obligately self-fertilizing plant species, for use in the study of temporal fluctuation in allele frequency and of the genetic structure within and among populations. • METHODS AND RESULTS We developed 28 primer pairs for L. inflata, all of which amplify CT dinucleotide rep...

The Mab 4B12 produced by us against capacitated boar spermatozoa was found to recognize a protein located in the acrosome portion of capacitated boar spermatozoa which is shared by different animal species, dogs included. It was shown that Mab 4B12 might affect fertilizing ability in vitro of boar spermatozoa. Using indirect immunofluorescence (IIF) test, we provide evidence here that Mab 4B12 ...

The yield of ratoon rice technology has the potential to match production main crop or first crop. As a result continuous chemical fertilization, paddy soil becomes acidic. This study aims obtain information on effectiveness neutralizing pH and fertilizing nutrients N, P, K in increasing rice. design used was randomized block with one factor, namely there were 7 types fertilization treatment fo...

Terpenoid production (emission and storage) within foliage plays direct and indirect defensive and protective functions for the plant, mediates complex trophic relationships and controls the oxidation capacity of the atmosphere. Both biotic and abiotic conditions alter terpenoid production, with herbivory, light and temperature effects being reasonably well understood. In this manuscript, the s...

The aim of this study is to underline the role of transmission and scanning electron microscopy analysis in the diagnosis of human sperm pathologies. Among the possible causes of male infertility, defects of sperm morphology represent an important factor that may explain decreased fertilizing potential of sperm. Electron microscopy allowed us to identify systematic sperm defects that affect the...

The carbon footprint is an index used to assess the impact of activity in terms greenhouse gas emissions. Viticulture contributes emissions due use fuels, fertilizers and pesticides, consequent soil erosion. Organic viticulture differs from conventional viticulture, mainly because absence synthetic products, tillage, level organic soil. purpose study was determine actual differences between vin...

Mounting an immune response against pathogens incurs costs to organisms by its effects on important life-history traits, such as reproductive investment and survival. As shown recently, immune activation produces large amounts of reactive species and is suggested to induce oxidative stress. Sperm are highly susceptible to oxidative stress, which can negatively impact sperm function and ultimate...

Mating multiply may incur costs, such as exposure to predators and to sexually transmitted diseases. Nevertheless, it may be favored, in spite of these costs, as a way to increase the genetic diversity of offspring through fertilization by multiple males. Here, we tested for multiple paternity in a freshwater snail (Potamopyrgus antipodarum), which is host to several species of sterilizing trem...

Internet of Things (IoT) data are mostly cloistered in closed IoT infrastructures and vertically integrated applications, failing to leverage the potential interlinking of corresponding APIs. We propose a data model based on JSON-LD, in which semantics are added to Web of Things (WoT) APIs, enhancing their interoperability and evolvability by the composition of nested contexts factoring out sha...
