The use of speckle laser to identify canopy variations in plants subjected to ultra-high diluted substances

:The reaction of plants to ultra-high dilute substances (UHD) is well known, however, the signaling of the immediate effect still doesn't have a widely accepted methodology. The objective of this experiment was to use non-destructive sampling to find signs of UHD soon after application to plants. Methods:The control consisted of untreated purslane [Pilea microphylla (L.) Liebm] plants and imaged with a digital cameraMobius (CMOS 1270x720 pixels) directed at a laser beam (±680 nm) emitted over the plant canopy for 220 seconds, with 6-second intervals. Then, the same plants were treated with Fluoricum acidum30CH (Fl. ac.30),and ten minutes later, new images of the leaves were taken to verify the possible existence of reaction patterns of the plants generated by Biospeckle Laser (1,2). Results:Several types of imaging were performed to choose the image pattern, and the NIR type was chosen, generated by the Mobius camera connected directly to a laptop (Figure 1). The images were treated using the THSP algorithm, which generated data to compare the variation of pixel intensity with and without the presence of UHD. Conclusion:Research has shown that "Fl. ac. 30" is identified in purslane plants soon after application and this sign persists for at least 180 minutesafter application, with a significant difference from the control at the 1% probability level.

Anti-hyperalgesic properties of ethanolic crude extract from the peels of Citrus reticulata (Rutaceae).

The therapeutic effects from Citrus reticulata on painful inflammatory ailments are associated to its flavonoids constituent and phytochemical studies with Citrus genus affirm that the peels have important amounts of it. These bioactive compounds have been a considerable therapeutic source and evaluate potential application of the peel extract is significant. This research aims to investigate the influence of ethanolic crude extract from the peels of Citrus reticulata and its possible mechanism of action in different animal models of pain. The extract reduced hyperalgesia in the second phase of formalin test (vehicle: 501.5 ± 40.0 s; C. reticulata extract 300 mg/kg: 161.8 ± 41.1 s), in the carrageenan model (vehicle at 4th h: 82.5 ± 9.6 %; C. reticulata extract 300 mg/kg at 4th h: 47.5 ± 6.5 %) and in Complete Freund's Adjuvant model (vehicle: 501.5 ± 40.0 s; C. reticulata extract 300 mg/kg: 161.8 ± 41.1 s). The possible contribution of opioidergic and adenosinergic systems in the anti-hyperalgesic effect of C. reticulata extract was observed after treatment, with non-selective antagonists for both systems, which produced reversal effects. In conclusion, these properties of C. reticulata extract suggest a potential therapeutic benefit in treating painful conditions.
