Transitioning gender identities is not linked with depression
2024-05-22
A landmark longitudinal study of LGBTQ+ youths has found that transitioning gender identities is not associated with depression and that about 1 in 3 gender-minority youths change their gender identity more than once. In fact, the study found higher rates of depression among transgender youths are more closely associated with bullying and victimization.
The findings from a team of researchers at The University of Texas at Austin and in Brazil are outlined in a paper in JAMA Network Open.
The study followed 366 LGBTQ+ young people ages 15-21 in two U.S. cities from 2011 to 2015 and measured depressive symptoms ...
Century-old vaccine protects type 1 diabetics from infectious diseases
2024-05-22
BOSTON--In new research, investigators at Massachusetts General Hospital (MGH) show that the 100-year-old Bacillus Calmette-Guérin (BCG) vaccine, originally developed to prevent tuberculosis, protects individuals with type 1 diabetes from severe COVID-19 disease and other infectious diseases.
Two back-to-back randomized double-blinded placebo-controlled trials found that the BCG vaccine provided continuous protection for nearly the entire COVID-19 pandemic in the US, regardless of the viral variant.
“Individuals with type 1 diabetes are highly susceptible to infectious diseases and had worse outcomes when they were infected with the SARS-CoV-2 virus,” ...
How and why different cell division strategies evolve
2024-05-22
Cell division is fundamental to life, enabling growth, reproduction, and survival across all organisms, from single-celled bacteria to complex multicellular animals. While animals and fungi share a common eukaryotic ancestry, their mechanisms of cell division, particularly mitosis, have diverged significantly, raising intriguing evolutionary questions.
Animals typically undergo open mitosis, where the nuclear envelope disassembles during cell division, while fungi exhibit closed mitosis, maintaining an intact nuclear envelope. The evolutionary reasons behind these divergent strategies ...
IPK research team uncovers mechanism for spikelet development in barley
2024-05-22
The inflorescence architecture of crop plants like barley is predominantly regulated by meristem activity and fate, which play a critical role in determining the number of floral structures for grain production. Spikelets are the basic reproductive unit of grass inflorescences. The identity and determinacy of many grass meristems are partially determined by a group of genes expressed specifically at organ boundaries, which can form local signalling centres that regulate adjacent meristem fate and activity.
These genes are critical for establishing and ...
Ancient DNA study reveals population history of Western Tibetan Plateau
2024-05-22
According to a study published in Current Biology on May 22, the genetic components of the ancient populations in the western Tibetan Plateau are closest to ancient populations in the southern Tibetan Plateau, and their major genetic components have been maintained over the past 3,500 years. In addition, these ancient populations in the western Tibetan Plateau had complex and frequent interactions with ancient populations inside and outside the plateau.
The study was conducted by Prof. FU Qiaomei's team from the Institute of Vertebrate Paleontology and Paleoanthropology ...
Exploring diversity in cell division
2024-05-22
Cell division is one of the most fundamental processes of life. From bacteria to blue whales, every living being on Earth relies on cell division for growth, reproduction, and species survival. Yet, there is remarkable diversity in the way different organisms carry out this universal process. A new study from EMBL Heidelberg’s Dey group and their collaborators, recently published in Nature, explores how different modes of cell division evolved in close relatives of fungi and animals, demonstrating, for the first time, the link between an organism’s ...
Sweet move: a modified sugar enhances antisense oligonucleotide safety and efficacy
2024-05-22
Researchers from Tokyo Medical and Dental University (TMDU) and Osaka University find that a newly developed modified sugar increases the efficacy and safety of antisense oligonucleotides designed to treat central nervous system disease
Tokyo, Japan – Diseases that affect the brain and spinal cord can be particularly devastating, and finding new and more effective ways to treat these conditions is an important goal for researchers and clinicians alike. Now, a research group from Japan reports that slightly modifying an existing treatment for central nervous system (CNS) disease dramatically increases its ...
Treatment options for hepatocellular carcinoma using immunotherapy: present and future
2024-05-22
Hepatocellular carcinoma (HCC), a prevalent form of cancer, profoundly influences the progression and prognosis of the disease through immune response mechanisms. The tumor microenvironment plays a pivotal role in fostering immune suppression and maintaining self-tolerance, which are crucial in developing and refining immunotherapy approaches.
In our comprehensive review, we initially delve into the characteristics of the tumor microenvironment in HCC, elucidating the predominant immunosuppressive mechanisms at play and the biomarkers pivotal for tracking the disease progression and therapeutic ...
