BACKGROUND Epistaxis is one of the commonest ENT emergencies and is experienced by up to 60% of people in their lifetime, with 6% requiring medical attention. The objective of the study was to determine the frequency of primary epistaxis and its relationship with temperature and relative humidity. METHODS This cross sectional study included 460 patients with epistaxis attending the ENT Depart...

Many plants are grown outside their natural ranges. Plantings adjacent to native ranges provide an opportunity to monitor community assembly among associated insects and their parasitoids in novel environments, to determine whether gradients in species richness emerge and to examine their consequences for host plant reproductive success. We recorded the fig wasps (Chalcidoidea) associated with ...

The collision of India with Asia, one of the most profound tectonic events to have occurred in past 100 m.y., is thought to have had geological, geochemical, and climatological consequences of global extent. Surprisingly the age of initiation of this collision remains poorly constrained. Estimates range from the Late Cretaceous (.65 Ma) to latest Eocene (,40 Ma), with little consensus in betwee...

The effect of exogenously applied auxins on oxidative stress was studied in six rootstock selections of Prunus cerasus, P. mahaleb and P. fruticosa aiming at the effect of phytohormones on the level of the lipid peroxidation (LP). Standard rootstock PHL-A was used as a control. Leaves were collected on 0, 1, 3 and 7 day of inserting cuttings into the rooting substrate. Auxin mixture consisted o...

A partial linkage map was constructed for the sweet cherry (Prunus avium L.) cultivar Emperor Francis from a population of 56 microspore-derived callus culture individuals. The callus cultures were genotyped for two allozymes and 90 random amplified polymorphic DNA (RAPD) markers using 79 random decanucleotide DNA primers and the polymerase chain reaction (PCR). Eighty-nine markers mapped to 10...

ABSTRACT Radiocarbon ( 14 C) in natural samples undergoes changes due to variations atmospheric CO 2 resulting from anthropogenic activities. To analyze the variation of C ratio , deciduous tree leaves were collected Gyeongju, a popular tourist city South Korea. Leaf Prunus subg. Cerasus trees at five different sampling points throughout over 3 years (2018, 2020, and 2021). The data categorized...
