(Press-News.org) About The Study: Researchers identified decreases of in situ and invasive melanoma diagnoses during 2020, which may reflect decreased skin cancer screening examinations or access to dermatologic care during the pandemic, both of which may lead to reduced melanoma diagnoses. This study adds to the current literature by highlighting that the relative increase in thick melanomas in 2020 was primarily associated with a marked decrease in thin melanomas, rather than an absolute increase in thicker melanomas.

Cannabis-involved traffic injury emergency department visits after cannabis legalization and commercialization
2023-09-06
About The Study: This study found large increases in cannabis involvement in emergency department visits for traffic injury over time in Ontario, Canada, which may have accelerated following nonmedical cannabis commercialization. Although the frequency of visits was rare, they may reflect broader changes in cannabis-impaired driving. Greater prevention efforts, including targeted education and policy measures, in regions with legal cannabis are indicated.

Furthest ever detection of a galaxy’s magnetic field
2023-09-06
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.
Lots of astronomical bodies in the Universe have magnetic fields, whether it be planets, stars or galaxies. “Many people ...
The first organic oscillator that makes catalysis swing
2023-09-06
Oscillating chemical systems are present at nearly every popular chemistry exhibition – especially the ones that display striking colour changes. But so far there are very few practical uses for these types of reactions beyond timekeeping. In nature, on the other hand, many important life processes such as cell division and circadian rhythms involve oscillations. Scientists at the University of Groningen have now developed an oscillating system that contains a catalyst, and exhibits periodic catalytic activity: this synthetic chemical oscillator can do more than just keep time. A description of this ...
Scripps Research chemists devise a method for C-H activation of alcohols
2023-09-06
LA JOLLA, CA—Scripps Research chemists have extended a powerful molecule-building method—called C-H activation—to the broad class of chemicals known as alcohols.
The synthetic chemistry feat, reported in Nature on September 6, 2023, follows the development of C-H activation techniques for the three other major classes of organic molecule—amines, acids and ketones—that are used to construct pharmaceuticals. It gives chemists a versatile new toolkit for making drugs and other valuable compounds now using the alcohol chemical class; moreover, its ...
Pitt researchers to study Alzheimer’s disease in marmosets
2023-09-06
PITTSBURGH – To reimagine existing preclinical trials for Alzheimer’s disease, University of Pittsburgh School of Medicine neuroscientists created the first non-human primate model of hereditary Alzheimer's in marmoset monkeys, outlining their approach in Alzheimer's & Dementia: Translational Research & Clinical Interventions.
Researchers are now working on characterizing and validating genetic, molecular, functional and cognitive features of aging and Alzheimer’s disease in marmosets that harbor mutations in the same gene that is linked to early-onset disease in humans. Scientists hope to accelerate the pace of the ...
Oral health deteriorates before and after bariatric surgery, study shows
2023-09-06
Oral health deteriorates in morbidly obese people on a diet in preparation for bariatric surgery and patients who have undergone the procedure, with increasing caries, gingivitis and periodontitis. This is the conclusion of a study conducted by researchers at the Federal University of São Paulo (UNIFESP) in Brazil. Articles on the study are published in the Journal of Oral Rehabilitation and Clinical Oral Investigations, stressing the importance of participation by a dentist in the assessment of bariatric patients.
The study was funded by FAPESP (projects 17/26400-6 and 16/10940-9), following 100 patients divided into two groups (dietary ...
Patients with AML who received vitamin C/D supplements had fewer complications, but no overall survival benefit seen
2023-09-06
Patients with acute myeloid leukemia (AML) who received vitamin C and D supplements while undergoing intensive chemotherapy had lower rates of complications, such as infections, bleeding, and inflammation, when compared with similar, previously treated patients who did not receive these supplements. Moreover, while the study showed no difference in survival between the two groups, a subgroup analysis showed that among patients with a genetic mutation known as NPM1 – found in about one in three patients with AML – the risk of death was nearly 50% lower among those ...
University of Colorado ophthalmologists administer novel treatment for single patient facing rare genetic condition
2023-09-06
Thirteen-year-old Grace Hoyt received potentially the best birthday gift ever this month when pediatric ophthalmologists at the University of Colorado School of Medicine and Children’s Hospital Colorado administered the first treatment designed specifically to slow her vision loss associated with posterior column ataxia with retinitis pigmentosa (PCARP), a rare genetic condition that affects vision and the nervous system.
“It’s so incredible that she has this opportunity,” Susan Hoyt says of her daughter, who received the first treatment Aug. 24. “We’ve known that Grace is going to go blind, but to have ...
Novel molecular design for enhanced efficacy and safety in radiotheranostics
2023-09-06
Radiotheranostics embodies the convergence of diagnostic and therapeutic radiopharmaceuticals into a unified platform. In cancer treatment, radiotheranostic procedures typically involve the use of antibodies that bind to proteins abundantly found on the surface of cancerous cells. The antibodies are labeled with a suitable radioisotope, which facilitates imaging procedures used to diagnose cancer and can be used to target cancerous cells and bombard them with deadly radiation as a form of treatment.
Although radiolabeled antibodies show promise as a treatment for cancer, several hurdles impede their clinical translation. ...
Potential target for reversing drug resistance in ovarian cancer identified
2023-09-06
For the 314,000 people diagnosed with ovarian cancer each year, hope often comes in the form of platinum-based drugs such as cisplatin.
Cisplatin causes the death of quick-dividing tumour cells, so it is a potent first-line defence in the treatment of the often fatal disease.
However, over half of ovarian cancer patients develop recurrence and become resistant to cisplatin and other platinum-based chemotherapies, contributing to the five-year survival rate of 31%.
It is unclear why this resistance occurs, but a solution is urgently ...
