Treating an open wound or surgical incision with stitches can potentially cause a variety of side effects: infection, scars, or dehiscence (the reopening of a wound). In a currently developing prototype, a new form of wound treatment externally and internally acts as a bandage, combining the knowledge of gecko adhesion, and a sugar-based glue. Created by Professor Robert Langer and Jeff Carp of the Massachusetts Institute of Technology, this gecko-inspired adhesive is biodegradable, biocompatible (does not cause inflammation), and flexible for the movement of tissues and muscles (Dougherty). As a result, nanoscale adhesive suggests a promising future for simplifying surgeries and implementing an easier recovery for patients through a chemically supported design. A gecko’s ability to climb a vertical surface relies solely on the geometrical makeup of hairs on each toe. In a grid-like pattern, each toe contains microscopic hairs called setae. These setae, once again magnified, split into triangular shaped hairs called spatulae at the tips. Millions of spatulae come into close contact to the surface, as each hair fits into the “ridges” and “peaks” of the molecular landscape. In both the surface, and the hairs of the gecko, protons and electrons continually move within the molecules. However once in extremely close proximity, an induced dipole occurs, and the molecules become either partially negative or positive. These attractions, when magnified by the millions of other spatulae contacting the surface, create stability for the gecko to climb the wall. Moving its feet parallel to the surface, the gecko is able to easily adhere to the surface, and then quickly detach its feet by pulling away perpendicularly from the surface - or at ... ... middle of paper ... ...ellar, and Anne M.

There are two types of chemical cross-linkers; synthetic and naturally derived reagents. The most commonly employed cross-linking reagent for collagen-based biomaterials is glutaraldehyde (GA), a five carbon bifunctional aldehyde, bridging ɛ-amino group of lysyl residues present in the protein over a varying range of distances owing to its less expensive and higher efficiency properties [16]. The mechanical properties of glutaraldehyde-treated tissue is quite different from non-cross-linked, showing more stiffness and increased tensile strength. However, GA is associated
Tissue engineering uses nanotechnology for tissue regeneration in order to fix damage tissue. In order to succeed tissue engineering utilizes two different methods: in vivo or in vitro regeneration of living tissue. Both methods use Nano scale scaffolds that are loaded with cells in order to regenerate a damage cell in the organ system. The scaffold can also be loaded with different molecules to assist in cell function lik...
In this regard, it is notable that News Corp Australia and Fairfax titles are, on average, read each week by around ‘60 per cent and 36 per cent respectively of the newspaper reading public in Australia’ (McKnight 2012). Fairfax publishes some of the country’s most influential newspapers, including The Australian Financial Review, The Sydney Morning Herald (SMH) and The Age.

When the physician applies the suture he/she uses a thread to perform the wound closure. Sutures can be nonabsorbable or absorbable. Absorbable sutures are when the body breaks down the suture over time and eventually dissolve. But usually nonabsorbable sutures are preferred because then the physician knows that the suture won’t dissolve before the full healing process is done. When the staples are used they may be circular staples to close the wound it depends on the wound.

The curcumin (197±14), laser (243±20), and laser + curcumin (231 ±33) treated groups significantly enhanced wound closure. compared to the control group (329 ±6.7),(One-way ANOVA, LSD test for all groups, p=0.000). We have observed that the curcumin group had significantly enhanced wound closure, compared to the laser, and laser + Curcumin treatedgroups ( LSD test, p=0.009, p=0.040, respectively)(Figure 2).

A Gecko’s foot contains, “dense clumps of projections” (Lewis, Tanya. “Biomimetics: 7 clever technologies inspired by nature.” Live Science. Purch. 22 Apr. 2013. Web). This allows the lizard to latch onto surfaces with no problem since the spatula like hairs dig into whatever surface they’re climbing. Such technology that gets “even stronger with use” (Lewis, Tanya. “Biomimetics: 7 clever technologies inspired by nature.” Live Science. Purch. 22 Apr. 2013. Web) can be used on climbing equipment to aid them and make climbing slightly easier. Generally 143 people a year get hurt while rock climbing, but if the Gecko’s method is used, it would greatly affect climbers and reduce their casualties

It’s a question that keeps floating around in the public sphere: is print advertising and newspapers dead? The world is becoming more and more fast-paced and although, our want and need for the up-to-date news and breaking stories has not changed, the way in which we consume it has. This background report investigates and explains the downfall of the newspaper and the technological shift to online news. It will also discuss differing opinions of this relevant topic of the future of journalism from a range of reliable primary sources and investigative data.
Newspapers: this is an old type of media that informs us of the news that is happening in the world around us. It is a document that is issued daily c...
