In order to plan a dental implant operation and the implant size and position, dentists need to know the exact location of the mandibular canal, a canal located in both sides of the lower jaw that contains the alveolar nerve.
Some solid tumors have a very high growth rate, which often leads to a lack of vascularization due to the impossibility to develop, at the same time, the blood vessels that accompany and nourish it. The team of Dr. Cristina Muñoz Pinedo, from the Bellvitge Biomedical Research Institute (IDIBELL) and the Faculty of Medicine and Health Science of the University of Barcelona (UB), with the collaboration of the Catalan Institute of Oncology (ICO), has studied how tumor cells respond to this lack of nutrients.
With stressed hospital services, and concerns about the spread of COVID-19, experts are reminding carers of children and young people of the importance of adhering to supported chronic condition self-management plans from the safety of their home.
Telehealth options, use of home-monitoring devices, keeping regular medical appointments and positive reinforcement from carers and health professionals are new ways to keep supported self-management plans on track, says Flinders PhD researcher Nicole Saxby, lead author on a study of key tools for program maintenance.
Osaka, Japan - Corneal diseases often require a transplant using corneal tissue from a donor. Now, researchers from Osaka University developed a novel method that could be used to generate corneal tissue in a lab more easily. In a new study published in Stem Cell Reports, they show how culturing eye cells derived from human induced pluripotent stem cells (hiPSCs) on specific proteins helped purify corneal epithelial cells (iCECs), which they then used to manufacture iCEC sheets that could be used for corneal therapy.
Scientists have identified a key step in the process that leads to leaky vessels and harmful swelling in eye diseases, according to a new study published today in eLife.
The discovery could lead to improved treatments for diseases such as age-related macular degeneration and diabetic retinopathy. These diseases cause leaky blood vessels to grow in the eyes, leading to harmful swelling and progressive vision loss.
Charisma can launch professional success and improve leadership skills. It can make a difference in a debate, make people become the center of attention and even be a factor in winning an election. However, humans do not have the monopoly on this inherent magnetism for triumph studied in so many coaching textbooks. It can also turn into an ally for certain living things in order to make their homes in a new ecosystem. Charismatic species have an easier time.
When looking at a left hand in the mirror, it looks like a right hand. However, the left hand never overlaps the right hand. Such a geometrical relationship that an image of the object in a plane mirror cannot be brought to coincide with itself is called chirality. A clockwise or counterclockwise helical staircase is an example of a chiral structure. On the other hand, a round ball is not chiral since its image in a mirror overlaps the original shape.
Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) and the Instituto de Investigación Sanitaria-Fundación Jiménez Díaz (IIS-FJD) in Madrid have demonstrated that a proteins present in early atheroma plaques--accumulations of cholesterol in the wall of arteries--could be used as a biomarker to detect atherosclerosis in the subclinical phase, before the appearance of symptoms.
Researchers from the Biophysics and Bioengineering Unit of the University of Barcelona have created a non-invasive low-cost ventilator, to support patients with respiratory diseases in areas with limited means. Researchers published the results of the study in the European Respiratory Journal together with open source technical features to build it.
Whether activating or silencing genes, breaking down defective cells or building new tissue, our body is constantly working to repair itself, even in cases of illness. To fight a disease, our body sends out signals, often long before we ourselves notice the disease. Such signals are, for example, DNA molecules that are released from the body's own cells, circulate in the blood and are most likely recognised by other cells as a message to stimulate a defence reaction.
