Cancer therapy: Integration of reactive oxygen species generation and prodrug activation

2021-07-06
(Press-News.org) Announcing a new article publication for BIO Integration journal. In this article the authors Xiao'en Shi, Xu Zhang, Xinlu Zhang, Haizhen Guo and Sheng Wang from Tianjin University, Tianjin, China discuss the integration of reactive oxygen species generation and prodrug activation for cancer therapy. The combination of chemotherapeutic drugs and reactive oxygen species (ROS) can improve cancer treatment outcome. Many ROS-generation strategies can specifically consume tumor-inherent oxygen and generate ROS, resulting in amplified ROS level and aggravated hypoxia. Therefore, the ROS generation strategy can integrate with prodrug activation strategy to realize synergetic therapy. In recent years, stimuli-responsive nanomedicines have been developed to realize the integration of ROS generation and prodrug activation. Triggered by a stimulus, nanomedicines can generate ROS at the tumor site, which can further activate the release of active drugs. The authors of this article summarize the latest progress of these nanomedicines and discuss the perspectives and challenges.

Satellite galaxies can carry on forming stars when they pass close to their parent galaxies

Satellite galaxies can carry on forming stars when they pass close to their parent galaxies
2021-07-06
Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the larger galaxy would remove the gas from it, leaving it shorn of the material it would need to make new stars. However, for the first time, a team led by the researcher at the Instituto de Astrofísica de Canarias (IAC), Arianna di Cintio, has shown using numerical simulations that this is not always the case. The results of the study were recently published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS). Using sophisticated simulations of the whole of the Local Group of galaxies, including the Milky Way, the Andromeda galaxy and their respective satellite ...

The evolution of vinegar flies is based on the variation of male sex pheromones

The evolution of vinegar flies is based on the variation of male sex pheromones
2021-07-06
By analyzing the genomes of 99 species of vinegar flies and evaluating their chemical odor profiles and sexual behaviors, researchers at the Max Planck Institute for Chemical Ecology show that sex pheromones and the corresponding olfactory channels in the insect brain evolve rapidly and independently. Female flies are able to recognize conspecific males through their specific odor profiles. Interestingly, closely related species show distinct differences in odor profiles, which helps to prevent mating between different species. Males, in turn, chemically mark females during mating so that they become less attractive to other males. The ...

High risk of divorce after TBI? Not necessarily, study suggests

2021-07-06
July 6, 2021 - Traumatic brain injury (TBI) has a major impact on the lives of affected patients and families. But it doesn't necessarily lead to an increased risk of marital instability, as two-thirds of patients with TBI are still married to the same partner 10 years after their injury, reports a study in the July/August issue of the Journal of Head Trauma Rehabilitation (JHTR). The official journal of the Brain Injury Association of America, JHTR is published in the Lippincott portfolio by Wolters Kluwer. For marriages that do end, divorce most often occurs within the first year after TBI, according to the new research by Flora M. Hammond, MD, of Indiana University School of Medicine, Indianapolis, and colleagues. "Our data dispel ...

Improved prediction of Indian Monsoon onset three months in advance using machine learning

Improved prediction of Indian Monsoon onset three months in advance using machine learning
2021-07-06
The onset of the Indian summer monsoon has been predicted three months ahead for the last 40 years with the highest precision up until today. The result indicates longer seasonal forecasts based on machine learning may be a way to mitigate the consequences of an erratic monsoon system under future global warming. Dr. Takahito Mitsui and Dr. Niklas Boers of the Potsdam Institute of Climate Impact Research (PIK Potsdam), Germany, published the results in Environmental Research Letters. The work is part of the European TiPES project, Coordinated from The Niels Bohr Institute, University of Copenhagen, Denmark and PIK Potsdam. Millions of people as well as natural habitats depend on the ...

Doctors warn against off-label use of new Alzheimer's drug for cerebral amyloid angiopathy

2021-07-06
BOSTON - A novel therapy recently approved by the U.S. Food and Drug Administration for patients with Alzheimer's disease amid considerable controversy should not be prescribed by physicians off-label for cerebral amyloid angiopathy (CAA), a similar cerebrovascular condition, according to Steven Greenberg, MD, PhD, director of the Hemorrhagic Stroke Research Program at Massachusetts General Hospital (MGH) and president of the International Cerebral Amyloid Angiopathy Association (ICAAA). In a letter published in The Lancet Neurology, Greenberg and eight other officers of the association wrote that there is no clinical evidence that the monoclonal antibody aducanumab is beneficial to patients with CAA, a condition in which proteins known ...

Relationship between chromosomal instability and senescence revealed in the fly Drosophila

Relationship between chromosomal instability and senescence revealed in the fly Drosophila
2021-07-06
Chromosomal instability is a feature of solid tumours such as carcinoma. Likewise, cellular senescence is a process that is highly related to cellular ageing and its link to cancer is becoming increasingly clear. Scientists led by ICREA researcher Dr. Marco Milán at IRB Barcelona have revealed the link between chromosomal instability and cellular senescence. "Chromosomal instability and senescence are two characteristics common to most tumours, and yet it was not known how one related to the other. Our studies indicate that senescence may be one of the intermediate links between chromosomal alterations and cancer," says Dr. Milan, head of the Development and Growth Control laboratory at IRB Barcelona. "The behaviour we saw in cells with chromosomal instability ...

Digital pens provide new insight into cognitive testing results

2021-07-06
(Boston)--During neuropsychological assessments, participants complete tasks designed to study memory and thinking. Based on their performance, the participants receive a score that researchers use to evaluate how well specific domains of their cognition are functioning. Consider, though, two participants who achieve the same score on one of these paper-and-pencil neuropsychological tests. One took 60 seconds to complete the task and was writing the entire time; the other spent three minutes, and alternated between writing answers and staring off into space. If researchers ...

Study reveals source of remarkable memory of "superagers"

2021-07-06
BOSTON -- As we age, our brains typically undergo a slow process of atrophy, causing less robust communication between various brain regions, which leads to declining memory and other cognitive functions. But a rare group of older individuals called "superagers" have been shown to learn and recall novel information as well as a 25-year-old. Investigators from Massachusetts General Hospital (MGH) have now identified the brain activity that underlies superagers' superior memory. "This is the first time we have images of the function of superagers' brains as they actively learn and remember new information," says Alexandra Touroutoglou, PhD, director of Imaging ...

Developing new techniques to build biomaterials

Developing new techniques to build biomaterials
2021-07-06
Scientists at the University of Leeds have developed an approach that could help in the design of a new generation of synthetic biomaterials made from proteins. The biomaterials could eventually have applications in joint repair or wound healing as well as other fields of healthcare and food production.   But one of the fundamental challenges is to control and fine tune the way protein building blocks assemble into complex protein networks that form the basis of biomaterials.   Scientists at Leeds are investigating how changes to the structure and mechanics of individual protein building blocks - changes at the nanoscale - can alter the structure and mechanics of the biomaterial ...

Studies add to concern about climate tipping

Studies add to concern about climate tipping
2021-07-06
Two model studies document the probability of climate tipping in Earth subsystems. The findings support the urgency of restricting CO2 emissions as abrupt climate changes might be less predictable and more widespread in the climate system than anticipated. The work is part of the European TiPES project, coordinated by the University of Copenhagen, Denmark but was conducted by Professor Michael Ghil, Ecole Normale Supérieure, Paris, France and coauthours from The Royal Meteorological Institute of Belgium and Parthenope University of Naples, Italy. Tipping could be imminent It is often assumed climate change will proceed gradually as we increase the amounts of CO2 in ...
