Super continuum generation in water doped with Homeopathic medicines

Int. j. high dilution res; 19 (1/2), 2020
We have carried out systematic studies to investigate the effect on supercontinuumgeneration in water using 40 fs laser pulses when doped with Homeopathic medicines. We perform these studies using five series of medications with different levels of dilution (10-30 to 10-100000). We measure su...

Efficacy of Azadirachta indica (Neem) leaf extract and hypertonic saline solution as intratesticular chemical sterilizing agents in dogs

Castration refers to induced sterility via physical, chemical, or hormonal methods. Chemical castration is an efficient and reliable technique in contrast to other sterilization procedures as it is less painful to physical methods and cost‑effective to hormonal methods. Azadirachta indica (neem), ...

Complete essential oils of Laurus nobilisinducing antinociceptiveaction by opioid mechanism in C-Reflex and spinal Wind-Up model in rat

The essential oil of Laurus nobilis L. was used to test their antinociceptive efficacy. It was applied intraperitoneally (i.p.) to rats subjected to a nociception test (C reflex and spinal wind-up). The results showed that the essential oil applied at higher doses (0.06 mg/Kg) causes a complete aboliti...

Ocotea pulchellaas an alternative against schistosomiasis: chemical analysis, development of nanoemulsion and biological control activity

The aim of this work was to evaluate the potential of the essential oil (EO) from Ocotea pulchella leaves as an alternative in the control of schistosomiasis. It was tested O. pulchella EO nanoformulation to assess its activity against adult Biomphalaria glabrata, their spawning and Schistossoma mansoni...
