Synergy of photoacoustic and fluorescence flow cytometry of circulating cells with negative and positive contrasts.
In vivo photoacoustic (PA) and fluorescence flow cytometry were previously applied separately using pulsed and continuous wave lasers respectively, and positive contrast detection mode only. This paper introduces a real-time integration of both techniques with positive and negative contrast modes using only pulsed lasers. Various applications of this new tool are summarized, including detection...
متن کاملFunctional synergy between antimicrobial peptoids and peptides against Gram-negative bacteria.
Antimicrobial peptides (AMPs) are integral components of innate immunity and are typically found in combinations in which they can synergize for broader-spectrum or more potent activity. Previously, we reported peptoid mimics of AMPs with potent and selective antimicrobial activity. Using checkerboard assays, we demonstrate that peptoids and AMPs can interact synergistically, with fractional in...
متن کاملPredictors of PTSD symptoms in brazilian police officers: the synergy of negative affect and peritraumatic dissociation.
BACKGROUND Exposure to traumatic events is a necessary but not a sufficient condition for the development of posttraumatic stress disorder (PTSD). Pretrauma, peritrauma and posttrauma factors interact to impact on symptom severity. The aim of the present study is to determine risk factors for PTSD symptoms in Brazilian police officers. METHOD In a cross-sectional sample of active duty officer...
متن کاملSouthern synergy.
Aflatoxin B, (AFB,) induced rat liver cancer is a well studied system of hepatocarcinogenesis. AFBI has also been used to transform cultured rat liver derived cells in vitro. Cells in culture often have a reduced capacity to metabolise the AFB, to its active metabolite, and often prolonged periods of exposure to the toxin have to be employed, with a long latency in the appearance of transformed...
متن کاملUnderstanding synergy.
Analysis of the interactive effects of combinations of hormones or other manipulations with qualitatively similar individual effects is an important topic in basic and clinical endocrinology as well as other branches of basic and clinical research related to integrative physiology. Functional, as opposed to mechanistic, analyses of interactions rely on the concept of synergy, which can be defin...
