Nagoya University researchers say they have designed a laser diode that emits the shortest-wavelength ultraviolet light to-date, with potential applications in disinfection, dermatology, and DNA analyses.

Examining the visual acuity of children who are younger than three years old is important for the early discovery of abnormal visual development, potential ophthalmic diseases, and neurological disease.
If the visual abnormal development is not diagnosed in time, later development will be affected, but performing visual examination in children is challenging due to their lack of understanding of instructions. Evaluating the visual acuity of children remains difficult since many children are unable to effectively express their understanding, especially with respect to directions (i.e., up, down, left and right). In addition, it is difficult for children to concentrate for a long time during the vision examination. The Teller visual acuity (TVA) card can be used to evaluate the visual acuity of children, but not all the operations are recorded and can be reviewed.
Abstract
A common and inexpensive drug may be used to counteract treatment resistance in patients with acute myeloid leukemia (AML), one of the most common forms of blood cancer. This is the conclusion of a study in mice and human blood cells performed at Karolinska Institutet and SciLifeLab and published in the medical journal EMBO Molecular Medicine. The researchers will now launch a clinical study to test the new combination treatment in patients.
Leukemia is a group of blood cancers that results in excess amounts of white blood cells. There are both chronic forms of leukemia that progress slowly over many years and acute types of leukemia that evolve rapidly. AML affects more than 20,000 people in the United States each year, and the mortality rate is high especially in older patients.
One of the most common drugs to treat AML is cytarabine (ara-C), a cytotoxic drug that interferes with DNA replication. However, many patients do not respond to the treatment because their leukemic cells express high levels of the enzyme SAMHD1, which breaks down the active metabolite of cytarabine, ara-CTP. These patients have a significantly worse survival rate than patients with low leukemic levels of SAMHD1. Therefore, one promising strategy to improve the treatment of AML is to inhibit the effects of this enzyme on cytarabine.
Marilyn had extensive fusion surgery all the way from her midback to the entire lower back. The surgery was done to fix her curvature in her spine.
Unfortunately, it did not help and she continued to have pain.
She has tried numerous injections and even strong pain killers which not only failed but also gave her side effects.
Her own bone marrow stem cells were extracted and after concentrating, they were injected back into her thoracic and lumbar discs.
The chemicals, known as PFAS, have been associated with cancer, liver damage, and developmental issues.
Advancements in neurotechnology are blurring the line between biology and technology. There is an emerging push to implant electronic devices inside the human body, hardwire them to our brains, and allow us to not only overcome disadvantages or injury but open up entirely new avenues of human experience.

Tau accumulation is associated with disease progression in Alzheimer’s disease. Here the authors use resting state fMRI and tau-PET to demonstrate that baseline connectivity in Alzheimer’s disease is associated with tau spreading.

During the last Alzheimer’s disease support meeting I attended at my mother’s assisted living center, I sheepishly asked if anyone else was worried about their own risk for the disease.
A lot of hands went up.
POHANG, South Korea, Jan. 15, 2020 — A research team from Pohang University of Science and Technology in South Korea (POSTECH) developed technology that allows diagnosis of diabetes and treatment of diabetic retinopathy by wearing smart light-emitting diode (LED) contact lenses.
