we collected 60 adult males and 85 adult females of trapelus lessonae de filippi, 1863 in early may 2008 from central iranian plateau to study sexual dimorphism in morphological traits as well as female reproductive traits. size-related sexual dimorphism occurred in all the compared body dimensions. the largest female was 83.88 mm in snout-vent length, and the largest male was 73.12 mm. as well...

The Caspian pond turtle, Mauremyscaspica, is a terrapin belonging to family Geoemydidae. Totally 130 specimens (67 males and 63 females) were collected manually and by net from different aquatic habitats in Golestan Province from 2016 through 2017. Morphometric characteristics such as length were measured using digital caliper and weight by electronic weighting scale. Skin of this turtle was da...

The use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. One of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. This research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

Endocytosis modulates cell responses by removing and recycling receptors from the cell surface. Type I angiotensin II receptors (AT1R) are somewhat unique in that they are expressed at apical (AP) and basolateral (BL) membranes in proximal tubule cells and both receptor sites undergo endocytosis. We analyzed AT1R cytoplasmic (-COOH) tail deletion mutants to determine whether classic AT1R endocy...

The goal of this section is to investigate the tilt-length correlations for the following alternative definitions of the tail director: A. Molecular directors, which characterize tilt of an entire molecule, rather than an individual tail. This approach to the director definition was taken in the earlier work [1–3]. Here, we investigate two different definitions of molecular directors (see Fig. ...

Myosin VIIA is an unconventional myosin, responsible for human Usher syndrome type 1B, which causes hearing and visual loss. Here, we studied the molecular mechanism of regulation of myosin VIIA, which is currently unknown. Although it was originally thought that myosin VIIA is a dimeric myosin, our electron microscopic (EM) observations revealed that full-length Drosophila myosin VIIA (DM7A) i...

—White-footed mice raised at 25° C have significantly longer tails at maturity than do mice raised at 15°C. The length of distal caudal vertebrae is more affected by temperature than that of proximal caudal vertebrae, suggesting a direct effect of temperature on tail growth. The results may be invoked to explain variation observed in nature, but extrapolations to free-ranging mice involve unver...

We studied the mechanical properties of deep red aerobic muscle of yellowfin tuna (Thunnus albacares), using both in vivo and in vitro methods. In fish swimming in a water tunnel at 1-3 L s(-1) (where L is fork length), muscle length changes were recorded by sonomicrometry, and activation timing was quantified by electromyography. In some fish a tendon buckle was also implanted on the caudal te...

A new recessive mutation affecting tail length is described. It is unlinked to the Tlt-complex on chromosome 17 and yet it shows cumulative phenotypic effects with several t-complex mutations: T, TCu, tct and Fu". It does not interact with five different nonchromosome I7 mutations that affect tail length. Thus, t-int is a tail modifier with surprisingly specific interactions. HE proximal part o...
