Although alternative splicing has been shown to give rise to isoforms of a number of transcription factors, such isoforms have not previously been detected for the POU homeodomain protein Pit-1. Screening of a rat pituitary GH3 cell cDNA expression library yielded a clone, termed pCMVPit-1a, encoding a 35.8 kD protein (Pit-1a) containing a 26 amino acid insert in the Pit-1 trans-activation doma...

This study was carried out on olive trees cv. Amygdalifolia, to investigate the effect of spraying potassium nitrate, KnO3, and zinc sulfate, ZnSo4, on the fruit weight, dimension and volume. The plants were sprayed with 0, 0.5, 1.0 and 1.5% KnO3 and 0, 0.25, 0.50 and 0.75% ZnSO4 and their combinations in August about halfway through the fruit growth period. The highest fruit weight was observe...

nowadays, cities are all filled up with improper and chaotic elements and ornaments; and the citizens, being drowned in such a chaos, are deeply in need of facing proper and emotionalizing atmosphere. undoubtedly bringing art and specifically “urban sculptures” into the realm of urban areas is one of the most influential ways to beautify and soften the urban settings and to build emotionalizing...

Measurement of multichannel continuous-wave near-infrared spectroscopy (CW-NIRS) is dependent on the modified Beer-Lambert law, which includes optical pathlength (PL) as an essential parameter. PLs are known to differ across different head regions and different individuals, but the distribution of PLs for the whole head has not been evaluated so far. Thus, using time-resolved near-infrared spec...

Recent studies have suggested that species-specific pit properties such as pit membrane thickness, pit membrane porosity, torus-to-aperture diameter ratio and pit chamber depth influence xylem vulnerability to cavitation. Despite the indisputable importance of using mean pit characteristics, considerable variability in pit structure within a single species or even within a single pit field shou...

The use of polymorphic markers in breeding programmes could make selection more accurate and efficient. A total of 324 individuals from six Iranian cattle populations (Sarabi, Golpayegani, Sistani, Taleshi, Mazandarani, Dashtiyari), F1 Golpayegani × Brown Swiss and Iranian buffalo populations were genotypedfor the Pit-1 HinfI and leptin Sau3AI polymorphisms by the polymerase chain reactio...

The influence of harvesting date on some physicochemical properties of nectarine (Prunus persica var. Red gold) fruit including fruit weight, pigment content, total carbohydrate, total phenol and antioxidant activity were studied. Fruits were harvested in four different stages; a) two weeks after fruit set, b) pit hardening, c) three weeks after pit hardening and 6 weeks after pit hardening. Re...
