“Magnetic fields affect biological systems. However, this is the first study on the effects of permanent magnetic fields (MFs) on the micropropagation of two ornamental plants, Spathiphyllum cv. i.e ‘Merry’ and Cymbidium Music Hour ‘Maria’. Cymbidium and Spathiphyllum shoots cultured in the ‘Miracle Pack’A (R) culture system were exposed PXD101 to MFs of different intensities, polarities, and duration of exposure. The results show that by increasing intensity from 5 x 10(-6) Tesla (T) as the geo-magnetic field to 0.1, 0.15, and 0.2 T negatively
influenced height and fresh mass of roots of Cymbidium plants (except for 0.1 T-S and 0.2 T-N treatments), but had no significant effect on other plantlet parameters. Long-term exposure (1, 2, or 3 mo) of Cymbidium shoots MLN4924 datasheet to 0.15 T-MFs negatively influenced plant
height, positively affected the number of leaves (with the exception of 0.15 T-S-1 mo), and had no clear effect on other parameters compared to the control. MFs (0.1, 0.15, and 0.2 T), regardless of their polarity, increased chlorophyll content (SPAD value) and the number of leaves, but slightly decreased the dry mass of Spathiphyllum shoots. Different exposure duration to 0.15 T (i.e., 2, 4, or 8 wk) had no significant influence on Spathiphyllum plantlet development other than increasing the SPAD value. These two ornamentals could serve as model systems to study plant development, space production, yield maximization, and the development of new morphotypes essential for the floricultural market.”
“Objectives: Selleck Buparlisib To examine the effects of electroacupuncture stimulation on behavioral changes and neuronal nitric oxide synthase expression in the rat spinal cord after nerve injury.\n\nMethods: Under pentobarbital anesthesia, male Sprague-Dawley rats were subjected to neuropathic surgery by tightly ligating and cutting the left tibial and sural nerves.
Behavioral responses to mechanical stimulation were tested for 2 weeks post-operatively. At the end of behavioral testing, electroacupuncture stimulation was applied to ST36 (Choksamni) and SP9 (Eumleungcheon) acupoints. Immunocytochemical staining was performed to investigate changes in the expression of neuronal nitric oxide synthase-immunoreactive neurons in the L4-5 spinal cord.\n\nResults: Mechanical allodynia was observed by nerve injury. The mechanical allodynia was decreased after electroacupuncture stimulation. Neuronal nitric oxide synthase expression was also decreased in L4-5 spinal cord by electroacupuncture treatment.\n\nDiscussion: These results suggest that electroacupuncture relieves mechanical allodynia in the neuropathic rats possibly by the inhibition of neuronal nitric oxide synthase expression in the spinal cord.
