virtual learning is a new idea that has gotten a new form with the emergence of new technologies such as the wireless networks. the mobile phone (cell phone) is a device that is used by most people nowadays. therefore, one can use the mobile phone for virtual learning on a wide scale. one of the popular and at the same time simple and inexpensive services on the mobile phone is the sms (short m...

Abstract Background Melatonin (MEL) is a powerful antioxidant molecule with anti-androgenic property. A microemulsion (ME) system loaded MEL was designed for treatment of androgenic alopecia. Pseudo-ternary phase diagram constructed, and ME formulae were developed using coconut oil, Tween 80 PEG 400. In the present study, characterized evaluated droplet size, polydispersity index, zeta potentia...

BACKGROUND From birth, the functional properties of the neonatal epidermal barrier mature whereby the stratum corneum (SC) hydrates and the skin surface acidifies. The identification of a thinner infant SC compared with adults suggests underdeveloped mechanisms underlying differentiation and desquamation. OBJECTIVES To assess the functional properties of the neonatal SC from birth, in conjunc...

Animal studies indicate Salacia reduces body weight, possibly due to its α-glucosidase inhibitor (α-GI) properties, but this has not been examined previously. In this study, a randomized, placebo-controlled, three-way cross-over design was used to evaluate whether Salacia Chinensis (SC) reduces appetite in healthy overweight/obese individuals (body mass index 28.8 ±3.6 kg/m²; 32 ± 12 years). Fo...

It is shown that the magnetic moments of Sc atoms can be significantly enhanced by combining them with alkali atoms. We present results of first principles electronic structure calculations of ScNa(n) (1 < or = n < or = 12) clusters that indicate that a ScNa(12) cluster consisting of a Sc atom surrounded by 12 Na atoms forming a compact icosahedral structure has a spin magnetic moment of 3 micr...

BACKGROUND Because of the slow pharmacokinetics of subcutaneous (SC) insulin, avoiding postprandial hyperglycemia has been a major challenge for an artificial pancreas (AP) using SC insulin without a meal announcement. METHODS A semiautomated AP with Technosphere® Insulin (TI; MannKind Corporation, Valencia, CA) was designed to combine pulmonary and SC insulin. Manual inhalation of 10 U ultra...

The explosion in the number of students taking online courses warrants a deeper understanding of instructor strategies that meet rhetorical and relational goals. Guided by social presence theory and rhetorical and relational goals theory, 329 participants were randomly assigned into one of three manipulated social presence online learning conditions to watch a short lecture. The student percept...

Telomerase expression is silenced in most adult somatic tissues with the exception of adult stem cell (SC) compartments, which have the property of having the longest telomeres within a given tissue. Adult SC compartments suffer from telomere shortening associated with organismal aging until telomeres reach a critically short length, which is sufficient to impair SC mobilization and tissue rege...

Physics Education Research (PER) is currently facing significant difficulties in disseminating research-based knowledge and instructional strategies to other faculty. Co-teaching is a promising and cost-effective alternative to traditional professional development that may be applicable in many situations. This paper discusses the rationale for coteaching and our initial experience with co-teac...
