We applied the Luria and Delbruck fluctuation test to analyze high-frequency changes in the phenotype of rat cells transformed by a plasmid carrying the polyomavirus middle T (pmt) gene. All of the transformed cell lines analyzed were capable of switching to the normal state with rates ranging from 10(-3) to 10(-2) per cell per generation. Analysis of both middle T antigen and middle T transcri...

A simple and cost-effective integrated synthesizer of fast light pulses has been designed, analyzed and tested for the characterization of the time response of photo-multipliers (PMT). This synthesizer consists of an integrated pulse generator based on Schmidt Trigger Inverters, a broadband matching network and a high speed LED. It enables the generation of pulses as short as less than 10 ns wi...

Malnutrisi dan obesitas merupakan masalah yang sering dialami oleh anak usia dini, untuk mengurangi tersebut perlu adanya pemberian makanan sehat dengan menu seimbang melalui program tambahan sekolah (PMT-AS). Sebagai salah satu Langkah mendukung keberhasilan PMT-AS maka peningkatan pengetahuan keterampilan guru PAUD walimurid edukasi. Metode pelaksanaan kegiatan ini yaitu partisipasi masyaraka...

UNLABELLED Pasteurella multocida toxin (PMT) induces atrophic rhinitis in animals, which is characterized by a degradation of nasal turbinate bones, indicating an effect of the toxin on bone cells such as osteoblasts and osteoclasts. The underlying molecular mechanism of PMT was defined as a persistent activation of heterotrimeric G proteins by deamidation of a specific glutamine residue. Here,...

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 conducte...

Reducing tobacco use among adolescents in China represents a significant challenge for global tobacco control. Existing behavioral theories developed in the West - such as the Protection Motivation Theory (PMT) - may be useful tools to help tackle this challenge. We examined the relationships between PMT factors and self-reported cigarette smoking behavior and intention among a random sample of...

This work deals with the statistical restoration of a hidden signal using Pairwise Markov Trees (PMT). PMT have been introduced recently in the case of a discrete hidden signal. We first show that PMT can perform better than the classical Hidden Markov Trees (HMT) when applied to unsupervised image segmentation. We next consider a PMT in a linear Gaussian model with continuous hidden data, and ...

BACKGROUND The coefficient of variation (CV) is defined as the standard deviation (sigma) of the fluorescent intensity of a population of beads or pixels expressed as a proportion or percentage of the mean (mu) intensity (CV = sigma/mu). The field of flow cytometry has used the CV of a population of bead intensities to determine if the flow cytometer is aligned correctly and performing properly...

INTRODUCTION Knee osteoarthritis (KOA) is a common, disabling and costly medical condition. The patellofemoral joint is a critical source of pain in individuals with KOA, and coexistence of patellofemoral osteoarthritis (PFOA) and tibiofemoral osteoarthritis (TFOA) is sometimes observed. The identification of subgroups with PFOA and customised interventions to correct underlying pathomechanics ...
