The emulsions assayed exhibited a different backscattering profiles regarding creaming destabilization hyperbolic and sigmoid one. Hyperbolic behavior can be described by a second order kinetics, where k_h could be equaled to a rate constant that describes the creaming process and its values would indicate the stability of emulsions. While for the sigmoid BS pattern, kinetics with two terms, is adequate to describe the creaming process in contrast to kinetics previously reported in the literature. The kh value has the same meaning as before, and ks indicates the delaying effect on the creaming rate.展开更多

The main aim was to evaluate the preliminary effects of Ocoxin cream® in the prevention of radiation therapy. Methods: Fifty patients were enrolled in an observational, longitudinal, prospective, single-centre clinical trial in the Department of Radiation Therapy at the National Institute of Oncology and Radiobiology in Havana, Cuba. The Radiation Therapy Oncology Group (RTOG) toxicity criteria were used to classify the radiation therapy, and the Dermatology Life Quality Index (DLQI) instrument was used to assess quality of life. Results: Patients who met the inclusion criteria were enrolled consecutively and were treated with teletherapy using a 60Co source with 1.25 MeV energy. 70.0% of the patients were head and neck cancer patients. No grade 3 - 4 radiation therapy was reported, nor were there any interruptions in radiation treatment due to skin toxicity. Radiation therapy was observed in only 14.0% of patients, and of these, only two patients developed grade 2 toxicity. The perception of quality of life before vs. after radiation therapy remained within an average range of “no effect” (at the start of radiation therapy) to “small effect” (at the end of radiation therapy). Conclusions: This clinical study is the first report of the use of Ocoxin cream® in cancer patients and demonstrates that it is able to prevent radiation therapy and reduce the severity of toxicity of treatment with ionising radiation.展开更多
