The objective of this research was to evaluate the clinical benefits of using a mini-instrument during endoscopic thyroidectomy via a breast approach (ETBA). Surgery-related indices and cosmetic results were compared for 20 patients underwent ETBA with a mini-instrument (ETBA-m) and 20 patients who underwent standard ETBA (sETBA). Patients were closely matched in terms of age, gender, tumor siz...

Rhodococcus sp. RHA1 induces two biphenyl dioxygenases, the BphA and EtbA/EbdA dioxygenases, during growth on biphenyl. Their subunit genes were expressed in R. erythropolis IAM1399 to investigate the involvement of each subunit gene in their activity and their substrate preferences. The recombinant expressing ebdA1A2A3etbA4 and that expressing bphA1A2A3A4 exhibited 4-chlorobiphenyl (4-CB) tran...

The adsorption and the redox behaviour of thrombine binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K and voltammetric behaviour of TBA and eTBA. ...

The adsorption and the redox behaviour of thrombin-binding aptamer (TBA) and extended TBA (eTBA) were studied using atomic force microscopy and voltammetry at highly oriented pyrolytic graphite and glassy carbon. The different adsorption patterns and degree of surface coverage were correlated with the sequence base composition, presence/absence of K(+), and voltammetric behaviour of TBA and eTB...

Introduction: The steel industry is known as the most important consumer of energy and fuel. In doing so, ensuring safety of energy sources of a country needs to expect the risks analysis in order to select a comprehensive approach. This study aimed to identify the energy consumption and control measures available in the Hot Rolling Kavir Steel Complex and to conduct risk assessment by Energy...

background and objective: prevention of accidents—a crucial requirement in oil industries—involves hazard recognition, risk assessment, and corrective actions. the purpose of this study was to compare the etba and hazop techniques for risk assessment in a gasoline refinery unit. methods: in this case study, data were collected using process flow diagram, walking–talking through method, piping a...

introduction: everyone who wants to analyze the safety needs to choose one method among all available ways. this study was carried out to identify energies and barriers in lpg storage spheres in a petrochemical complex using etba method. it also examines the quantitative evaluation of failure modes and their effects as well as evaluation of effect of fmea and comparing the results plus the iden...
