Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (NTAD). We aimed to find a correlation between the length of this polymorphic tract and azoospermia or oligozoospermia in infertile men living in Khuzestan, Iran. MaterialsAndMethods In this case-control study during two years till 20...

BACKGROUND To date, the only estimate of the heritability of telomere length in wild populations comes from humans. Thus, there is a need for analysis of natural populations with respect to how telomeres evolve. METHODOLOGY/PRINCIPAL FINDINGS Here, we show that telomere length is heritable in free-ranging sand lizards, Lacerta agilis. More importantly, heritability estimates analysed within, ...

An experiment was carried out to determine the length, weight, and Length-Weight Relationship of mature hilsa, Tenualosa ilisha, in Bangladesh better manage fish species. Total 480 Samples were collected from Meghna River, Chandpur, July 2012 June 2013 Tentulia Barisal, 2014. length (TL) measured using a measuring scale, body weight (BW) taken an electric balance. Length-weight relationship (LW...

The crystal structure of a synthetic sulfosalt, TlsAsS4, has been refined. The crystal is orthorhombic with space group Pnma .. Four formula units are contained in a unit cell of dimensions a = 0.8893(3), b = 1.0868(5) and c = 0.9088(3) nm. The final R-value is 0.04 for 759 observed reflections. The Tl(l) has seven nearest S atoms with a mean Tl-S bond length of 0.329 nm. Tl(2) has five nearest...

onion is one of the important strategic crop plants of a highly valuable nutritional food source, consumed almost around the whole world. thus, the genetically oriented studies around the plant are valuable and inevitable. for a following of these studies, some onion masses from various regions throughout iran, including: kashan-white, azarshahr-red, isfahan-dorcheh, ghom-white, zanjan-gholighe...

This is the first study of growth and age of Sardinella sindensis from coastal waters of Qeshm Island (Persian Gulf) based on the sectioned otolith reading method. In total, 128 fishes were collected randomly from purse seine commercial nets during March 2011 to February 2012. The annual formation of the growth rings were determined by counting the opaque and translucent zones occurrence at the...

in order to genetic analysis of rice seed vigour, a cross was carried out between tarom mahalli (tolerant to osmotic stress) and khazar (sensitive to osmotic stress) crosses. linkage map based on ssr markers was derived using 74 polymorphic markers and 192 f2 individuals. germination rate, radicale and plumule length were recorded from 20 plants per 192 f3 families. the loci related to germinat...

early body shape changes of beluga sturgeon were studied using landmark-based geometric morphometric approach to recognize its allometric growth pattern. sampling was done from hatching up to 50 days post hatching (dph). left side of specimens were photographed using digital camera and nine landmark points were digitized on two-dimensional images. total length (ti) was measured using the softwa...
