A parabolic dish microphone is like a mirror telescope for sound. A parabolic reflector is used to collect and focus sound waves to a microphone receiver [1, 2]. The parabolic shape has the property that all sound waves impinging parallel to the central axis of the dish are reflected to its focus point. When the dish is aimed at a distant sound source it is safe to assume that all the sound wav...

Motor neuron (MN) diseases are progressive disorders resulting from degeneration of neuromuscular junctions (NMJs), which form the connection between MNs and muscle fibers. NMJ-in-a-dish models have been developed to examine human MN-associated dysfunction with disease; however such coculture models have randomly oriented myotubes with immature synapses that contract asynchronously. Mechanicall...

Over the years it has been an important goal to optimize the treatment of subfertility in order to obtain a better pregnancy rate and baby-take-home rate, usually combined with the goal of decreasing the rate of multiplet pregnancies. This implies optimizing the development of embryos through improved in vitro culture methods. And it also implies optimizing the methods of selection of embryos f...

Background: The aim of the present study was to develop a three-dimensional (3D) collagen gel culture system for the in vitro growth and survival of buffalo preantral follicles with or without growth factors. Materials and Methods: Buffalo ovaries were collected from a local abattoir and preantral follicles were isolated through microdissection. Isolated preantral follicles were put either in c...

this case report illustrates the presence of diffuse idiopathic skeletal hyperostosis (dish) in a fighting bulldog. the dog was referred to the veterinary teaching hospital, university of agriculture faisalabad pakistan, with the presenting complaint of slowly progressing staggering gait, inability to stand on hind limbs and muscle stiffness in lumbo-sacral region. hematological, serobiochemica...

A bioassay for tyrothricin, based on a procedure used by Szybalski in bacterial resistance studies, was developed. Replacement of the tube dilution assay with this procedure represented economy in time and equipment, with a resultant increase in productivity. The procedure involved preparation of special agar plates which provided graded concentrations of tyrothricin along a horizontal axis. A ...

The study aimed at controlling the mycelial growth and germination of Mycosphaerella fijiensis in Petri dish by using three plant defense stimulators. Approximately, 2 mL each stimulator (Vacciplant®, Callel® calliete®) were added to different M. culture media. results obtained show that Vacciplant® promote vitro contrary calliete® which inhibits it. Indeed, it causes total mortality (100%) con...

PURPOSE Extracellular matrices were tested for their ability to support the adhesion and proliferation of human corneal endothelial cells. METHODS Human corneal endothelial cells were plated onto tissue culture dishes coated with purified fibronectin or a matrix elaborated by cultured bovine corneal endothelial cells. The presence of human cells in the cultures was confirmed by karyotyping. C...

STUDY DESIGN Retrospective cohort study. PURPOSE The purpose of this study was to evaluate the prevalence of diffuse idiopathic skeletal hyperostosis (DISH) in patients with spinal diseases determined by roentgen images of the whole spine. OVERVIEW OF LITERATURE Although several studies have investigated the prevalence of DISH in healthy subjects, no detailed data have been reported on the ...

An embryo culture of an inbred strain of Syrian hamster developed into a permanent cell line under the "3T3" 3 X 10-5 cells/60-mm dish. The resulting cell line had properties very similar to those of the mouse 3T3 series and was named HAMS 3T3. The cell showed density-dependent inhibition of division with a saturation density of 1.0 to 1.2 x 10-6 cells/60-mm dish or 4.5 to 5.5 x 10-4 cells/sq c...
