*Recent Applications of Biosensors*🔵📝✒
*Measurement of Metabolites*:⏳⌛
In intensive care units for example, patients frequently show rapid variations in biochemical levels that require an urgent remedial action. Also, in less severe patient handling, more successful treatment can be achieved by obtaining instant assays. At present, the list of the most commonly required instant analyses is not extensive. In practice, these assays are performed by analytical laboratories, where discrete samples are analyzed, frequently using the more traditional analytical techniques
*Diabetes*:💢
Diabetic patients have a relative or absolute lack of insulin, *a polypeptide hormone produced by the beta-cells of the pancreas*, which is essential to the metabolism of a number of carbon sources. This deficiency causes various metabolic abnormalities, including higher than normal blood glucose levels. For such patients, insulin must be supplied externally. This has usually been achieved by *subcutaneous injection*, but fine control is difficult and *hyperglycaemia* cannot be totally avoided, or even *hypoglycaemia* is sometimes induced, causing impaired consciousness and the serious long-term complications to tissue associated with this intermittent low glucose condition.
*Artificial Pancreas*. The introduction of a closed-loop system, where integrated glucose measurements provide feedback control on a pre-programmed insulin administration based on habitual requirement, would therefore relieve the patient of frequent assay requirements and perhaps more desirably frequent injections. Ultimately, the closed-loop system becomes an artificial pancreas, where the glycaemic control is achieved through an *implantable glucose sensor*. Obviously, the requirements for this sensor are very different to those for the discrete measurement kits.✔

Technology Today:
New sensor technology could speed up blood test analysis🔬
Researchers at the University of York have developed a new sensor that is capable of detecting multiple proteins and enzymes in a small volume of blood, which could significantly speed up diagnostic healthcare processes.

Currently tests to detect the presence of infection or disease require a sample of blood from a patient, which is later analysed in a laboratory to detect markers of disease. The presence of particular proteins can give an indication of a health condition and the best course of treatment, but only one type of protein can be identified per sample.
If multiple tests are required, as is the case in the suspected presence of cancer cells or resistant infection, the delivery of results can take longer and the costs of testing increases.

The team at York, however, have developed a biosensor that combines light and electricity, to detect multiple disease biomarkers in one smaller sample of blood.

The technology could make blood tests more comfortable for patients and enable results to be processed quicker.

These sensors can give fast, real time results and at low cost. The length of time and money that it takes laboratory technicians to identify just one protein in a patient sample is a real challenge for the NHS and can result in emotional distress for patients.

Not only can this new technology speed the process up, but it can test for a number of proteins and enzymes together in just one sample, increasing the chances of a successful and timely diagnosis.

Rare electromagnetic bursts called 'sprites' that form above thunderstorms were captured at 10,000 frames per second. Sprites are large-scale electrical discharges that occur high above thunderstorm clouds, or cumulonimbus, giving rise to a quite varied range of visual shapes flickering in the night sky.

That's what we need ;)

La prothèse totale de hanche se compose de cinq parties en matériaux variés selon les exigences et la situation du patient :
• La tige fémorale, insérée dans le fémur percé au préalable. Cette partie est le plus souvent en titane et recouverte d’hydroxyapatite pour la compatibilité. Elle est parfois réalisée sur mesure (malformations notamment).
• Le col, très souvent lié à la tige, lui aussi en titane.
• La tête, qui s’emboîte sur le col, généralement en acier, en cobalt ou en céramique.
• Le cotyle prothétique, fixé dans le bassin du patient, en titane recouvert d’hydroxyapatite (comme la tige. Ce sont en effet les deux parties de la prothèse en contact direct avec l’os).
• L’insert, placé dans le cotyle et chargé de la liaison entre la tête du fémur et le cotyle, en polyéthylène (polymère simple à synthétiser), en céramique ou en métal pour assurer la fluidité de l’articulation.
