element detector module and still yield a practical design. In this paper we report results of measurements made on a 64 element detector module made with LSO scintillator crystal. We present performance results for a prototype PET detector module consisting of 64 LSO scintillator crystals (3x3x20 mm) coupled on one end to a single photomultiplier tube and on the opposite end to a 64 pixel arra...

background: skin cancer is a serious public health problem in the world. its prevalence in many countries has been increased in recent years. this study aimed to assess the effects of a theory-based educational intervention to promote skin cancer preventive behaviors (scpbs) among rural farmers in chalderan county, iran.   methods: this was a quasi-randomized controlled field trial study conduc...

The protein toxin Pasteurella multocida toxin (PMT) is the causative agent of atrophic rhinitis in pigs, leading to atrophy of the nasal turbinate bones by affecting osteoblasts and osteoclasts. The mechanism of PMT-induced intoxication is a deamidation of α-subunits of heterotrimeric G proteins, including Gαq, Gα13, and Gαi, thereby causing persistent activation of the G proteins. Here we util...

Two micro crystal element (MiCE) detector unit designs are evaluated. The detector units are built using highly packed arrays of 0.8 0.8 6 mm mixed lutetium silicate (MLS) crystals. The first detector unit, MiCE1, consists of a 5 5 array of 0.8 mm 0.8 mm 6 mm MLS crystals. The detector unit is coupled to four channels of a Hamamatsu multichannel photomultiplier tube (PMT) via a 2 2 array of 2 m...

BACKGROUND The aim of this study is to evaluate the clinical value of a prophylactic minitracheostomy (PMT) in patients undergoing an esophagectomy for esophageal cancer and to clarify the indications for a PMT. METHODS Ninety-four patients who underwent right transthoracic esophagectomy for esophageal cancer between January 2009 and December 2013 were studied. Short surgical outcomes were re...

The potent mitogenic toxin from Pasteurella multocida (PMT) is the major virulence factor associated with a number of epizootic and zoonotic diseases caused by infection with this respiratory pathogen. PMT is a glutamine-specific protein deamidase that acts on its intracellular G-protein targets to increase intracellular calcium, cytoskeletal, and mitogenic signaling. PMT enters cells through r...

We discuss the estimation of random errors due to shot noise in backscatter lidar observations that use either photomultiplier tube (PMT) or avalanche photodiode (APD) detectors. The statistical characteristics of photodetection are reviewed, and photon count distributions of solar background signals and laser backscatter signals are examined using airborne lidar observations at 532 nm using a ...
