This design uses virtual reality (VR) tools to conduct detailed examinations of human melanoma and disease progression and possible treatment. The tests will use a ConfocalVR systems. Instead of viewing cell images as a three-dimensional model on a flat computer screen, clinicians and researchers will be able to project cell images from normal and diseased tissue into a VR space, see detailed images of internal structure and directly interact with the three-dimensional images in virtual reality.

Patients themselves can immerse themselves in the VR space and view the VR images using our tools. ImageJ software free from the National Institutes of Health (NIH) is used to convert confocal microscope image stacks into 3D volumetric object files (NIfTI ) that ...

Problem statement:
Detection and calculation of malaria parasitemia in human blood smear

Introduction:
Malaria represents a serious public health problem for humans and animals worldwide. Malaria is endemic in more than 100 countries while the majority of the cases occurs in tropic countries. Estimation of parasitemia (in stained blood smears) is an important parameter in malaria diagnosis and malaria research; however it is being perform manually since binging, which is a time consuming method. In contrast this study proposes a Python (Open CV) based image processing tool for easy, user friendly, accurate and cost effective calculation of parasitemia. During this process, initially the malaria positive blood smear image was acquired and a Python Code for Image Processing was developed ...

Traditionally, orthopedic surgeons have relied upon surgical screws to stabilize bone fractures. However, these screws often need to be removed due to pain and inadequate performances, causing surgical device removal surgeries to account for over 30% of all planned orthopedic surgeries. Screws have protruding heads that make them prone to catching on nearby muscle and nervous tissue, causing immense pain for patients. Additionally, screws occupy a large portion of the medullary canal, impeding bone tissue healing. Screws also often “back out”, or loosen, which requires costly followup surgery to redo them. These concerns would be resolved with our product, FastenPro.

FastenPro fastens a wire perpendicular to the fracture, through the bone, to be secured on either end by stainless ...

"CATCH" is a low cost, user-friendly, self-testing device which detects HIV. In emerging nations, this promotes individuals (who are prevented from travelling for miles to see a physician) to test for HIV at home.

Unfortunately, many individuals lack schooling due to a multitude of variables in emerging nations (including gender inequality, lack of infrastructure, poverty - the list goes on). CATCH is highly intuitive and anyone can use it. It is intended to do all the user's thinking and operates in three simple measures:
1. Sliding the disinfectant sleeve over the finger
2. Push down on the pipette/needle top
3. Press the button to see the result

This simple device has the potential to save millions of lives due ...

We introduce a low-cost pipette tip-based ELISA platform “ELISA in a Tip” as a next generation assay tool with lower cost, better sensitivity, shorter time, low sample and reagent volumes than traditional ELISA. Our platform could serve as a simple microfluidic adaptor that encourages to blend microfluidic advancement, multiplexing and smartphone integration with widely practiced gold standard ELISA without need for major overhaul of current infrastructure in hospitals and testing laboratories.

Pipette-tip adapters represent the first engineering advancement in decades-old well established diagnostic technique "ELISA." Tips were produced using a desktop 3D printer and were designed to fit most commercially available bench-top pipettes. Unlike ELISA which require extensive training and specialized technicians, pipette-tip ELISA users needs to know basic ...

Tests on anchovies show that when plastic is mixed with salt water and begins to disintegrate it releases an odor which is similar to krill. The enticing smell sets off foraging and feeding behaviour in fish, causing them to eat the debris, believing it is food. Previously scientists thought that fish were ingesting tiny particles of plastic by accident when they were hoovering up floating pieces of plankton or krill. But the new study suggests the problem is even more serious because fish are actually attracted to the plastic.

A recent study estimated that nine in 10 of the world’s seabirds now have pieces of plastic in their guts, mainly through eating fish which have ingested plastic. A recent ...

The occurrence of wounds or deep injuries in patients located in very distant places, places in conflict or even, in outer space, where the transportation of the patient can be very complicated or it can take days to carry the patient to an attention place, generates risk for lives of people located in these places or circumstances.

In this context, it is necessary to stop the bleeding, protect the wound or injurie and provide a way for the beginning of the tissue repair from the moment the treatment is started. This implies that, in a device, it is necessary to include a solution for hemostasis, providing support at the cellular level for tissue growth and initiation of repair through ...

Nearly 300,000 Americans have sustained some form of spinal cord injury (SCI), and effective therapies to promote recovery of neural function are lacking. Our vision is to create an off-the-shelf spinal cord implant to replace the injured tissue.

We used the natural spinal cord architecture as a template to design a scaffold that mimics the intact cord. We chose materials with mechanical properties that are similar to the spinal cord properties in order to allow superior integration. We then used rapid 3D printing technology that can fabricate the implant in one continuous print, rather then layers as being done by common inkjet 3D-printers. The interface between each layer is a mechanically weak area; our method produce a more stable ...

It is said that the main causes of sudden death in elder people are heart failures and risk of falling. Diagnosis and prevention of heart diseases and fall detection is more and more important in our daily life. In addition to increased population growth, online telemedicine systems are useful due to the possibility of timely and efficient healthcare services. The rapid growth in technology has remarkably enhanced the scope of remote health monitoring systems. Loss of consciousness and fall-induced injury is one of the leading problems faced by the elderly. They are the leading cause for the transfer of senior citizens from the comfort of their residence to assisted care environments. They also account for 40% of injury related deaths ...

Currently, the bags don't have the best design for our back, because the design of those bags was made a long time ago and until now they were keeping the same parameters about where they had been sewn and its points of tension, I mean: the forces are converging and match with our body, directly with our back, shoulders, and neck. The design of the current bags is not the most accurate for our backs and they are very uncomfortable when you have to carry books, some electronics, or very heavy things, especially the mountain bag; or for long periods of time, as school backpacks! My solution is to make a new bag with a new design to help ...
