The structure and relations of the mesoglea, muscle-fibres, aitd cell layers were examined by several histological techniques. Evidence is given that the muscle-fibres represent specializations of the mesogleal substance, and they are therefore referred to as mesogleal fibres. The longitudinal fibrous system is regularly demonstrable in the body of the animal and the circular system in its tent...

We present results of our search for X-ray line emission associated with the radiative decay of the sterile neutrino, a well-motivated dark matter candidate, in Suzaku Observatory spectra of the Ursa Minor dwarf spheroidal galaxy. These data represent the first deep observation of one of these extreme mass-to-light systems and the first dedicated dark matter search using an X-ray telescope. No ...

Katakori is a symptom name that is unique to Japan, and refers to myofascial pain syndrome-like clinical signs in the shoulder girdle. Various methods of pain relief for katakori have been reported, but in the present study, we examined the clinical effects of multi-acupuncture point injections (MAPI) in the acupuncture points with which we empirically achieved an effect, as well as the anatomi...

Propagation of incoherently soliton pairs in photorefractive crystals under steady-state conditions is studied. These soliton states can be generated when the two mutually incoherent optical beams with the same polarization and wavelength incident on the biased photorefractive crystal. Such soliton pairs can exist in bright-bright, dark-dark, gray-gray as well as in bright-dark types. In this p...

Lotty Ackerman, Matthew R. Buckley, Sean M. Carroll, and Marc Kamionkowski California Institute of Technology, Pasadena, California 91125, USA (Received 16 December 2008; published 23 January 2009) We explore the feasibility and astrophysical consequences of a new long-range Uð1Þ gauge field (‘‘dark electromagnetism’’) that couples only to dark matter, not to the standard model. The dark matter...

background: increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. while, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. objectives: the present study was designed to investigate a comparative study on the infl...

muscle biopsy has been used for a long time for diagnosis of muscular, nerurogenic and systemic disorders with muscle involvement, because only very few of these disorders show sufficient specific clinical features for definite diagnosis. since the presence of difficulties in the screening of numerous genes, muscle biopsy could be a time and cost effective procedure for solving the diagnostic p...

introduction hemangiomas are the most common benign tumor of infancy that can occur anywhere in the body. intramuscular hemangiomas (imh) are accounting for approximately 1% of all cases and the muscles of extremities are the most common sites. because of scarcity and variable clinical features of these tumors, we decided to report a case of imh in the upper lip mucosa. case report the patient ...
