Over past several years, the cold plasma-stimulated medium (PSM) has shown its remarkable anti-cancer capacity in par with the direct cold plasma irradiation on cancer cells or tumor tissues. Independent of the cold plasma device, PSM has noticeable advantage of being a flexible platform in cancer treatment. Currently, the largest disadvantage of PSM is its degradation during the storage over a...

Dear Editor, Propriospinal myoclonus (PSM) is characterized by jerks arising in axial muscles that spread to more caudal and rostral segments along propriospinal pathways. PSM at sleep onset is a subtype of PSM that occurs during the sleep–awake transition and causes severe sleep-onset insomnia.1 Previous case reports have focused on the etiology and mechanism of PSM, but have not evaluated tre...

There has been a recent surge in the number of disasters and incidents in occurring in the process industry (e.g. the petrochemical, chemical, food and pharmaceutical industries). The reasons include defects in process-safety management (PSM); inadequate safety management systems in companies; inadequate knowledge among managers and insufficient information about the tasks undertaken and result...

PSM-E is a newly discovered alternatively spliced variant of prostate-specific membrane antigen (PSMA). In the current study, its role on the proliferation, invasiveness and migration in prostate cancer cell lines was analyzed. PSM-E and PSMA (as a comparison) eukaryotic expression vectors pcDNA3.0/PSM-E and pcDNA3.0/PSMA were constructed, validat...

When we use a PSM what is it we are actually doing? An answer to this question would enable the PSM community to considerably enlarge the available source of case studies by the inclusion of examples of non-codified PSM use. We start from Checkland’s own proposal for a “constitutive definition” of SSM, which originated from trying to answer the question of knowing when a claim of SSM use was le...

CONTEXT This review focuses on positive surgical margins (PSM) in radical prostatectomy (RP). OBJECTIVE To address the etiology, incidence, and oncologic impact of PSM and discuss technical points to help surgeons minimize their positive margin rate. An evidence-based approach to assist clinicians in counseling patients with a PSM is provided. EVIDENCE ACQUISITION A literature search in Eng...

Purpose: To compare the outcomes of prognosis of positive surgical margins (PSM) and negative surgical margins (NSM) after partial nephrectomy (PN). We performed this study to assess local recurrence, distant recurrence and survival rates after PN. Materials and Methods: We searched PubMed, Web of science and the Cochrane Library. Three independent reviewers extracted data using a standardized ...

PURPOSE The study was undertaken to identify factors affecting perception of the importance and practice of patient safety management (PSM) among hospital employees in Korea. METHODS This study was conducted using a descriptive design and a self-report questionnaire. Two hundred and eighty employees were recruited from three hospitals using a convenience sampling method. Measures were percept...

a r t i c l e i n f o This research aims to evaluate the state of the art of Purchasing and Supply Management (PSM). This is carried out through a wide, in-depth, and structured examination of published works. More than one thousand papers (i.e., 1055) published in 20 peer-reviewed journals were collected and analyzed to provide a snapshot of PSM research, including the extent of the overall pr...
