The accuracy of sentinel lymph node biopsy in the treatment of multicentric invasive breast cancer using a subareolar injection of tracer.
2008
BACKGROUND: The aim of this study was to evaluate the feasibility and the accuracy of sentinel lymph node biopsy in multicentric breast cancer (MBC) performed by means of a subareolar (SA) injection of both 99Tc-labeled human albumin colloid and lymphazurin. METHODS: Between January 2002 and October 2007, 34 patients with MBC with clinically negative axilla underwent sentinel lymph node biopsy (SLNB) followed by total axillary node dissection (AD). Overall successful identification rate of SLN was 100%; there were no false negatives and overall accuracy rate was 100%. RESULTS: The mean number of sentinel lymph nodes (SLNs) identified was 1.8 +/- 0.88 (range = 1-4); the mean number of axilla…
Infracyanine Green vs. Brilliant Blue G in Inverted Flap Surgery for Large Macular Holes: A Long-Term Swept-Source OCT Analysis
2020
Background and Objectives: To compare the long-term toxicity of infracyanine green (IFCG) to brilliant blue G (BBG) in inverted internal limiting membrane flap surgery (I-ILMFS) for large, full-thickness macular holes (FTMHs). Materials and Methods: Prospective randomized study including 39 eyes with &ge
Control of freshwater fish louse Argulus coregoni: a step towards an integrated management strategy
2008
Harmful infections by ectoparasites of the genus Argulus occur repeatedly in freshwa- ter fish farming operations where the management has largely been ineffective. Preventative meth- ods and regular monitoring are rarely applied, so that chemical interventions become necessary. According to the Integrated Pest Management (IPM) approach, a sustainable management or control program for a parasite should be based on knowledge of the ecology of the parasite along with adop- tion of several prevention and control methods, the application of which is dependent upon the pre- vailing infection level. The application of multiple management tactics is especially important because parasites can devel…
Neuronal nitric oxide synthase is involved in CB/TRPV1 signalling: Focus on control of hippocampal hyperexcitability
2017
Cannabinoids (CB), transient receptors potential vanilloid type 1 (TRPV1) and nitric oxide (NO) were found to be interlinked in regulating some neuronal functions such as membrane excitability and synaptic transmission. TRPV1 play a fundamental role since it represents a synaptic target for CB that triggers several downstream cellular pathways. In this regard, recent evidence report that TRPV1 could influence NO production by modulating neuronal NO synthase (nNOS) activity. In the present research, we pointed to manipulate nNOS function to assess its role on TRPV1 signalling in hyperexcitability conditions elicited in the dentate gyrus of hippocampal formation. The activation of TRPV1 recep…
Decarboxylation and alkaline colour fading reactions in presence of humic substances.
2002
Humic substances (HSs) can substantially influence velocity of reactions in the environment as shown on example of decarboxylation and alkaline colour (e.g., malachite green and crystal violet) fading reactions. In colour fading and decarboxylation reactions of 6-nitrobenzisoxazole-3-carboxylic acid HS act as inhibitors, but additions of surfactants change the pattern of reaction. The inhibitory activity of HSs much depends on their origin. The velocity of studied reactions depends also on pH, temperature and concentration of HS used. Possible micellar catalysis mechanism has been suggested.
