Anti-microbial activities of novel nanoformulated lactoferrin through oral administration

A biomolecular delivery system consisting of a novel alginate enclosed, chitosan coated ceramic antimicrobial nanocarrier containing lactoferrin (AEC-CP-Fe-bLf) and development of this multifunctional bovine iron saturated lactoferrin nanotechnology based drug delivery systems for finding treatment to parasitic and bacterial diseases was prepared. Since lactoferrin is a naturally occurring molecule its clinical application would be welcome.

An international survey of daily disposable contact lens prescribing

The aim was to determine the extent of daily disposable contact lens prescribing worldwide and to characterise the associated demographics and fitting patterns. Up to 1,000 survey forms were sent to contact lens fitters in up to 40 countries between January and March every year for five consecutive years (2007 to 2011). Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Survey data collected since 1996 were also analysed for seven nations to assess daily disposable lens fitting trends since that time. Data were collected in relation to 97,289 soft lens fits, of which 23,445 (24.1 per cent) were with daily disposable lenses and 73,170 (75.9 per cent) were with reusable lenses. Daily disposable lens prescribing ranged from 0.6 per cent of all soft lenses in Nepal to 66.2 per cent in Qatar. Compared with reusable lens fittings, daily disposable lens fittings can be characterised as follows: older age (30.0 ± 12.5 versus 29.3 ± 12.3 years for reusable lenses); males are over-represented; a greater proportion of new fits versus refits; 85.9 per cent hydrogel; lower proportion of toric and presbyopia designs and a higher proportion of part-time wear. There has been a continuous increase in daily disposable lens prescribing between 1996 and 2011. The proportion of daily disposable lens fits (as a function of all soft lens fits) is positively related to the gross domestic product at purchasing power parity per capita (r(2) = 0.55, F = 46.8, p < 0.0001). The greater convenience and other benefits of daily disposable lenses have resulted in this modality capturing significant market share. The contact lens field appears to be heading toward a true single-use-only, disposable lens market.

Airplane grows in the tummy of clouds: living through relations in the early years of life

Using a child's expression that illustrates his mental image of constituted relations of living things, the author conceptualizes relationality, an interrelated view of being, and its importance for early childhood education. The difference between relation and interaction, and the significance of inter-human relationship are discussed as significant aspects for early childhood teachers to understand as they work with children. In particular, this paper seeks to provide insights into the potential contribution of relationality towards early childhood teaching practice.

Activities between activities of focus-Relevant when assessing DNA transfer probabilities

Consideration of the indirect transfer of 'touch DNA' is increasingly becoming part of criminal investigations. Focus is often concentrated on the actions relating to the pick-up of the relevant DNA and key actions associated with transfer to the exhibit from which the sample in question was collected. There is often a time lapse between such actions. As any contact can influence the gain and/or loss of DNA, it is relevant to have an awareness of what hands touch during everyday activities in order to assist consideration of what may be occurring during potential time lapses within contemplated scenarios. To gain an appreciation of the manner and frequency of hands contacting various surfaces during everyday activities, we analysed several videos of individuals performing a variety of general activities. The findings indicate that several items are touched over a relatively short period of time. Appreciation and consideration of general activities that may have occurred between key focus activities are necessary to assess any impact these may have on what is deposited at the final collection site. The information this provides is imperative when weighting alternative transfer scenario propositions.
