The aim of research was to determine polyphenols bioaccessibility and antioxidant properties thermally-treated skimmed goat milk enriched with sunflower bee-collected pollen through in vitro digestion. HPLC analysis confirmed that pollen-enriched contained flavonols as the main phenolic fraction (80.7–76.2%) followed by acids (14.2–17.4%). Among individual compounds quercetin-3-O-glucoside (155...

low seed yield is a limiting factor for cross breeding and hybrid seed production in cyclamen. this study was performed to investigate pollen germination and its relation to cross-pollination success and fruit set in this plant. in order to achieve a high level of pollen germination, the effect of different concentrations of chemical compounds were examined on in vitro pollen germination of cyc...

iran is one of the main date (phoenix dactylifera) producing countries in the world. however, little information is available on the pollen viability and favorable storage conditions of iranian male date cultivars. this study was conducted to estimate the best in vitro pollen germination of three male date palm cultivars, `ghanami’, `samsmavi’ and `gheibani’ using various doses of boric acid (0...

Background: Alongside hazel, alder and birch pollen allergies, ash pollen allergy is a relevant cause of hay fever during spring in the European region. For some considerable time, ash pollen allergy was not routinely investigated and its clinical relevance may well have been underestimated, particularly since ash and birch tree pollination times are largely the same. Ash pollen extracts are no...

In this study, we discuss an approximate set of equations describing water wave propagating in deep water. These generalized Klein–Gordon (gKG) equations possess a variational formulation, as well as a canonical Hamiltonian and multi-symplectic structures. Periodic travelling wave solutions are constructed numerically to high accuracy and compared to a seventh-order Stokes expansion of the full...

Worldwide, 400 million people suffer from hay fever and seasonal asthma. The major causative agents of these allergies are pollen specific proteins called the group-1 grass pollen allergens. Although details of their antigenicity have been studied for 40 years with an eye towards immunotherapy, their function in the plant has drawn scant attention. Zea m 1 constitutes a class of abundant grass ...

The goal of this research project was oriented around the hypothesis that drifting talc powder from seed hoppers planting in a field causes honey bee mortality. It is known that seed treatment manufacturers are required to examine the toxicity of the individual components but are not required to examine the toxicity of the cocktail that makes up the entire seed treatment. We hypothesized that t...

molecular evidence on the heterogeneity present in the ole e 1 allergen of the olive pollen is emerging. such polymorphism is dependent on the cultivar origin of pollen, which also determines wide differences in the expression of this protein. determination of biochemical and molecular characteristics of ole e 1 pollen allergen in two iranian olive cultivars, namely 'rowghani' and 'zard' is nec...

This study was carried out in order to determine the effects of boron and cold stress on pollen germination of almond hybrids in vitro culture, two different media including the absence and presence of boron (0 mg/l, and 100 mg/l) in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different treatments had a significant effect on the germination percentage. The...
