Artificial neural network for predicting pathological stage of clinically localized prostate cancer in a Taiwanese population
submitted by rozon 37 minutes ago - Topic: Health
We developed an artificial neural network (ANN) model to predict prostate cancer pathological staging in patients prior to when they received radical prostatectomy as this is more effective than logistic regression (LR), or combined use of age, prostate-specific antigen (PSA), body mass index (BMI), digital rectal examination (DRE), trans-rectal ultrasound (TRUS), biopsy Gleason sum, and primar...



Protein profiles secreted from phylloplane of rice leaves free from cytosolic proteins: Application to study rice-M. Oryze interactions
submitted by amish 39 minutes ago - Topic: Agriculture
Magnaporthe oryzae causes rice blast disease, which threatens global rice (Oryzae sativa) production. We identified proteins secreted during rice blast infection by performing proteomics analysis of rice phylloplane secreted proteins. Apoplastic proteins were analyzed by two-dimensional electrophoresis and MALDI-TOF mass spectrometry. The biological functions of proteins induced by M. oryzae in...

Vacuolar Na+/H+ NHX-Type Antiporters Are Required for Cellular K+ Homeostasis, Microtubule Organization and Directional Root Growth
submitted by osebliy 41 minutes ago - Topic: Biology
Na+/H+ antiporters (NHXs) are integral membrane transporters that catalyze the electroneutral exchange of K+ or Na+ for H+ and are implicated in cell expansion, development, pH and ion homeostasis and salt tolerance. Arabidopsis contains four vacuolar NHX isoforms (NHX1–NHX4), but only the functional roles for NHX1 and NHX2 have been assessed thus far. Colocalization studies indicated that NH...

Hydrophilic carbon clusters as therapeutic, high-capacity antioxidants
submitted by osebliy 42 minutes ago - Topic: Biology
Oxidative stress reflects an excessive accumulation of reactive oxygen species (ROS) and is a hallmark of several acute and chronic human pathologies. Although many antioxidants have been investigated, most have demonstrated poor efficacy in clinical trials. Here we discuss the limitations of current antioxidants and describe a new class of nanoparticle antioxidants, poly(ethylene glycol)-funct...

Genetic effect of locus B2 inhibiting awning in double-ditelosomic 6B of Triticum durum DR147
submitted by sajotho 47 minutes ago - Topic: Agriculture
Plentiful awn variations have been discovered in hexaploid wheats, while less were observed in diploid and tetraploid wheats. However, a double ditelosomic line of 6B (dDT6B) in tetraploid wheat cultivar DR147 specifically displayed awnless phenotype, which arised from the presence of awning inhibitor B2 located in telosome 6BL derived from hexaploid wheat cultivar Chinese Spring (CS). B2 locus...



Estimation of mechanical properties of seeds of common vetch accessions (Vicia sativa L.) and their chemical composition
submitted by sajotho 47 minutes ago - Topic: Agriculture
The attempt was made to estimate the mechanical loads on seeds, taking into account their geometric properties and chemical composition. Material chosen for the study comprised 46 samples of common vetch representing collection accessions originated from Europe. Additionally, accessions of other legume species were involved. The study included determinations of seed thickness and weight of 1,00...

Bunium persicum: variability in essential oil and antioxidants activity of fruits from different Iranian wild populations
submitted by sajotho 47 minutes ago - Topic: Agriculture
The fruits of Bunium persicum (Boiss.) B. Fedtsch were collected throughout Iran from ten populations and assessed for their essential oil composition and antioxidant activity. The volatiles were analyzed by GC/MS/FID after microdistillation and SPME. All 10 accessions had the same major volatiles roughly in the order γ-terpinene = cuminal > γ-terpinen-7-al > p-cymene > limonene > ...


Diversity, distribution and horticultural potential of Cordia myxa L.: a promising underutilized fruit species of arid and semi arid regions of India
submitted by sajotho 47 minutes ago - Topic: Agriculture
Cordia myxa L. locally known as Gonda, Lasora or lehsua belongs to family Boraginaceae. It grows throughout India except in high hills and temperate climates. This is a perennial, medium sized tree with crooked stem. It bears small sized fruits in bunches, used as traditional vegetable and pickles. Besides, it has number of other uses including medicine, fuel wood and ornamental wood work. Due ...

Assessing genetic diversity of Egyptian hexaploid wheat (Triticum aestivum L.) using microsatellite markers
submitted by sajotho 47 minutes ago - Topic: Agriculture
Genetic diversity was investigated in a set of thirty-three hexaploid wheat genotypes originated from Egypt, using 17 wheat microsatellites, representatives of fifteen wheat chromosomes. In total, ninety-five alleles were detected among Egyptian wheats. For 17 polymorphic microsatellite markers, the number of alleles per locus varied from 3 for Xgwm261-2DS, Xgwm3-3DL and Xgwm631-7AS to 11 for X...


Diversity and genetic structure of the husk tomato (Physalis philadelphica Lam.) in Western Mexico
submitted by sajotho 47 minutes ago - Topic: Agriculture
Physalis is an American plant genus that includes species of economic importance for their edible fruit. Consumption of this fruit is a historic tradition in Mexico. Physalis philadelphica is one of the most abundant species, which can grow under wild, weedy or cultivated conditions. It presents high morphological variability in terms of vegetative and reproductive traits; however, no study has...

Molecular analysis of diversity of diploid Triticum species in Iran using ISSR markers
submitted by sajotho 47 minutes ago - Topic: Agriculture
Genetic diversity of wild wheats germplasm especially those growing in center of origin is of critical value for breeding proposes. In this study 89 accessions belonging to the three species (T. monococcum, T. urartu, T. boeoticum), collected all around Iran, were analysed using nine inter-simple sequence repeat (ISSR) primers. Polymerase chain reactions amplified 170 DNA fragments, from which,...


Promoting competitiveness of neglected and underutilized crop species: comparative analysis of nutritional composition of indigenous and exotic leafy and fruit vegetables in Ghana
submitted by sajotho 47 minutes ago - Topic: Agriculture
Ghana is endowed with a lot of indigenous leaf and fruit vegetables which are nutritious and are used in the treatment of many ailments. However, current changes in food habits in both rural and urban households have led to overdependence on energy-rich but nutrient poor staple crops. Most of these non-indigenous staple crops are not adapted to local conditions in Ghana as compared to indigenou...

What policies should be implemented to develop a gaseous transport industry in Ireland?
submitted by eve 51 minutes ago - Topic: Environment
Gaseous transport has been successful in European countries such as Germany, Italy and Sweden. However, the majority of European countries have seen little market penetration of gas-powered vehicles. The utilisation of gaseous transport fuels in Ireland, like in many countries, is currently overlooked as a sustainable option to satisfying the European Union renewable transport target of 10% by ...

The role of CO2 emissions from large point sources in emissions totals, responsibility, and policy
submitted by eve 52 minutes ago - Topic: Environment
A large fraction of anthropogenic CO2 emissions comes from large point sources such as power plants, petroleum refineries, and large industrial facilities. The existence and locations of these facilities depend on a variety of factors that include the distribution of natural resources and the economy of scale of operating large facilities. These large facilities provide goods and/or services we...
