Staphylococcal species acquire antibiotic resistance by incorporating the mobile-genetic element SCCmec. We previously found that SCCmec-encoded psm-mec RNA suppresses exotoxin production as a regulatory RNA, and the psm-mec translation product increases biofilm formation in Staphylococcus aureus. Here, we examined whether the regulatory role of psm-mec on host bacterial virulence properties is...

PURPOSE We compared location of positive cores in biopsy and location of positive surgical margin (PSM) following radical prostatectomy. MATERIALS AND METHODS This retrospective analysis included patients who were diagnosed as prostate cancer by standard 12-core transrectal ultrasonography guided prostate biopsy, and who have PSM after radical prostatectomy. After exclusion of number of biops...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

Staphylococcus epidermidis releases factors that activate the HIV-1 long terminal repeat, induce cytokine release, and activate nuclear factor B in cells of macrophage lineage. The active material had a mass of 34,500 daltons, was inactivated by proteases and partitioned into the phenol layer on hot aqueous phenol extraction, and thus was termed phenol-soluble modulin (PSM). High performance li...

Abstract Process Safety Management (PSM) is a management system that is focused on prevention of, preparedness for, mitigation of, response to, and restoration from catastrophic releases of chemicals or energy from a process plant. Existing PSM such as OSHA/PSM guidelines just indicate the elements, but consistency between elements is not ensured and practical level of elements is different eac...

INTRODUCTION RP (radical prostatectomy) technique continues the major treatment option for men with potential cure and life expectancy exceeding 10 years. The aim of the study is to assess the impact of PSM on BR (biochemical relapse), to identify PSM risk factors, to clarify the factors involved in BR in the absence of PSM. MATERIAL AND METHODS Consultation of 171 medical-records from patien...

The miscibility behavior of palmitoyl sphingomyelin (PSM) with phytosterol derivatives of β-sitosterol (SITO), β-sitosteryl glucoside (SG), and β-sitosteryl glucoside palmitate (SGP) was systematically investigated using Langmuir monolayers. The surface pressure (π)-molecular area (A) and surface potential (ΔV)-A isotherms for binary PSM/SITO, PSM/SG, and PSM/SGP systems on 0.02 M Tris buffer w...

BACKGROUND Positive surgical margins (PSM) are recognized as an adverse prognostic sign and are often associated with higher rates of local and systemic disease recurrence. The data regarding the oncological outcome for PSM following radical nephrectomy (RN) is limited. We examined the predictive factors for PSM and its influence on survival and site of recurrence in patients treated with RN fo...

the establishment of good process safety management (psm) is widely considered as the most effective means of improving safety levels in process industries. this study was conducted to evaluate the feasibility of establishing and implementing psm requirements based on occupational health and safety assessment series 18001 standards (ohsas 18001) and health, safety and environment management sys...

Organizing PSM into a some library for reuse reveals two related problems that have thus far received little explicit attention: What is the scope of reuse of a PSM? How distinctive/similar are PSM? In considering the first question, the working hypothesis in constructing such libraries, and in particular the CommonKADS library, has been that PSM are task specific, and that therefore the major ...
