Introduction: Medications used to treat oral ulcers include corticosteroids, anesthetics, and antihistamines. These can be as gels, mouthwashes, pastes, ointments, etc. Diphenhydramine hydrochloride (DPH) has local anesthetic properties that help the aphthae. One of drawbacks delivery transmucosal is quick turnaround time gel, a mucous form located on epithelial film surface. Methods: Therefore...

BACKGROUND AND OBJECTIVES Low level laser therapy (LLLT) has been used to promote hair growth. A double-blind randomized controlled trial was undertaken to define the safety and physiologic effects of LLLT on males with androgenic alopecia. METHODS Forty-four males (18-48 yo, Fitzpatrick I-IV, Hamilton-Norwood IIa-V) were recruited. A transition zone scalp site was selected; hairs were trimme...

Background: Unlike iron ruthenium is not an essential element for life. However, the behavior of ruthenium compounds in biological systems and, in particular their use as antitumour agents has attracted much attention recently. This study aims to determine antitumour properties against human tumour cell line HeLa of pentamethylcarboxylate ruthenocene. Methods: This is an in vitro study by apply...

Graphene is considered as one of the most promising materials for post silicon electronics, as it combines high electron mobility with atomic thickness [Novoselov et al. Science 2004, 306, 666-669. Novoselov et al. Proc. Natl. Acad. Sci. U.S.A. 2005, 102, 10451-10453]. The possibility of chemical doping and related excellent chemical sensor properties of graphene have been demonstrated experime...
