Virtual Reality for Supporting the Treatment of Depression and Anxiety: Scoping Review

Posted by in categories: biotech/medical, neuroscience, virtual reality

Conclusions: Most studies demonstrated the use of VR to be effective for supporting the treatment of anxiety or depression in a range of settings and recommended its potential as a tool for use in a clinical environment. Even though standalone headsets are much easier to work with and more suitable for home use, the shift from tethered VR headsets to standalone headsets in the mental health environment was not observed. All studies that looked at the use of CBT either in vivo or in a virtual environment found it to be effective in supporting the treatment of anxiety or depression.

Keywords: CBT; anxiety; depression; mental health; virtual reality.

The biological switch that could turn neuroplasticity on and off in the brain

Posted by in categories: biotech/medical, media & arts, neuroscience

The Conversation Weekly podcast is taking a short break in August. In the meantime, we’re bringing you extended versions of some of our favourite interviews from the past few months.

This week, how researchers discovered a biological switch that could turn on and off neuroplasticity in the brain – the ability of neurons to change their structure. We speak to Sarah Ackerman, a postdoctoral fellow at the Institute of Neuroscience and Howard Hughes Medical Institute at the University of Oregon, about what she and her team have found and why it matters.

The Nano Robots Inside You

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

Inside of you, at all times, there are trillions of natural nano robots walking around, taking out the trash, and packaging strands of DNA. Below the calm, ordered exterior of a living organism lies a complex collection of molecular machines working together to create something greater than themselves. Physicist and author of “Life’s Ratchet” Peter Hoffmann shows us the tiny city beneath the surface.

Discovered an aging “brake pedal”?

Posted by in categories: biotech/medical, life extension, neuroscience

How does the research conducted by Lige Leng at the Institute of Neuroscience of Xiamen University in China (I link it to you here)? It all starts with the study of the “inflamed brain”: many diseases of old age are associated with low-level chronic inflammation in the brain, organs, joints and circulatory system. A phenomenon sometimes called “inflammaging”.


You know it: over time all of our body’s repair systems deteriorate, our DNA and proteins accumulate damage, metabolism stumbles and cells stop doing their job. That’s life, beauty.

We’re all on our way to the exit, but research on worms, flies, mice and monkeys show that going at this speed isn’t inevitable. Diet and lifestyle changes (and, perhaps, upcoming anti-aging drugs) can curb decay and give us many more years of life, especially healthy life.

Suppression of FOXO1 attenuates inflamm‐aging and improves liver function during aging

Posted by in categories: biotech/medical, genetics, life extension

Several factors contribute to the development of inflamm-aging, including genetic susceptibility, visceral obesity, microbiota and gut permeability, cellular senescence, NLRP3 inflammasome activation, oxidative stress caused by mitochondrial dysfunction, immune cells dysregulation, and chronic infection (Ferrucci & Fabbri, 2018). The immune system becomes gradually dysregulated during aging, leading to elevated blood levels of pro-inflammatory mediators, such as TNFα, IL6, and C-reactive protein (Harris et al., 1999 ; Mooradian et al., 1991). Energy homeostasis also becomes dysregulated with aging, which results in the redistribution of subcutaneous fat to visceral regions and contributes to inflammation (Bouchard et al., 1993 ; Chumlea et al., 1989 ; Curtis et al., 2005). Metabolism-induced inflammation, also known as metaflammation, shares similarities with inflamm-aging, including the elevation of certain circulating pro-inflammatory cytokines (Prattichizzo et al., 2018). Therefore, the molecules that play a key role in the regulation of metabolic homeostasis potentially mediate the development of chronic inflammation during aging.

Forkhead box O1 (FOXO1) transcription factor has been indicated to be involved in the regulation of nutrient metabolism and energy homeostasis (Cheng et al., 2009 ; InSug et al., 2015 ; Matsumoto et al., 2007 ; Yang et al., 2019 ; Zhang et al., 2012). Deletion of hepatic Foxo1 improves glucose homeostasis in insulin resistant mice (Dong et al., 2008). FOXO1 inhibition by AS1842856 attenuates hepatic steatosis in diet-induced obesity mice (Ding et al., 2020). In mature macrophages, FOXO1 promotes inflammation through the activation of TLR4-and STAT6-mediated signaling pathways (Fan et al., 2010 ; Lee et al., 2022). In invertebrates, DAF-16, the Foxo homolog gene, mediates the effect of insulin/IGF signaling on lifespan (Ogg et al., 1997). Overexpression of FOXO in Drosophila and C.elegans increases their lifespan (Giannakou et al., 2004 ; Henderson & Johnson, 2001). However, studies in mammalians show that FOXO1 does not have a significant correlation with longevity (Chiba et al., 2009 ; Kleindorp et al., 2011). Considering the role of FOXO1 in regulating glucose metabolism and inflammation, we hypothesize that FOXO1 plays an important role in the regulation of aging-induced inflammation and dysregulation of glucose homeostasis.

Liver is an important metabolic organ that plays a key role in maintaining whole-body nutrient homeostasis by regulating energy metabolism, clearing xenobiotic and endobiotic, and synthesizing necessary molecules (Rui, 2014). As a result, aging-induced changes in liver contribute to systemic susceptibility to aging-related diseases. Different types of liver cells, including hepatocytes, endothelial cells, hepatic stellate cells (HSC), and macrophages, are all affected by the aging process (Hunt et al., 2019). However, most studies on liver aging focused on whole-liver tissue, which is mainly composed of parenchymal cells, hepatocytes. Thus, the effects of aging on liver nonparenchymal cells (NPCs) are less understood. In this study, we used bulk RNA-Seq and single-cell RNA (scRNA)-Seq technologies to analyze aging-induced changes, and the role of FOXO1 in aging-related processes in both whole-liver and individual liver cells, particularly liver macrophages. We found that insulin resistance, liver fat accumulation, liver inflammation, and systemic inflammation were significantly aggravated in old mice. Additionally, aging significantly increased pro-inflammatory response in Kupffer cells (KCs) and induced a functional quiescence in monocyte-derived macrophages (MDMs). FOXO1 activity was significantly enhanced in the livers of old mice and FOXO1 inhibition improved insulin resistance, hepatic steatosis, and inflammation in old mice. Furthermore, we found that FOXO1 inhibition attenuated aging-induced pro-inflammation in KCs and had a limited effect on aging-induced functional quiescence in MDMs. Taken together, this study indicates that FOXO1 plays an important role in the liver aging processes and suggests that FOXO1 is a potential therapeutic target for the treatment of aging-induced chronic diseases.

Scientists develop finger sweat test to detect antipsychotic drugs in patients

Posted by in categories: biotech/medical, health

Antipsychotic drugs treat incredibly vulnerable patients. Maintaining a treatment regimen is difficult for many patients, but not taking the medication is associated with a higher risk of poor health outcomes. These drugs are also very powerful with strong side effects, and blood tests are often used to calibrate a patient’s dosage and confirm that they are taking the recommended dose.

However, blood tests are invasive and potentially uncomfortable. Scientists have now discovered a way to test the levels of common in the sweat from patients’ fingerprints, offering a quicker, more comfortable, and more convenient alternative to blood draws for patient monitoring.

“Our test offers patients a quick and dignified way of showing commitment to antipsychotic treatment,” said Katherine Longman of the University of Surrey, first author of the study in Frontiers in Chemistry. “This non-invasive approach can also be adapted to fit other therapeutic regimes.”

Diabetes reversed in mice with genetically edited stem cells derived from patients

Posted by in categories: biotech/medical, genetics

Researchers at Washington University School of Medicine in St. Louis have transformed stem cells into insulin-producing cells. They used the CRISPR gene-editing tool to correct a defect that caused a form of diabetes, and implanted the cells into mice to reverse diabetes in the animals. Shown is a microscopic image of insulin-secreting beta cells (insulin is green) that were made from stem cells produced from the skin of a patient with Wolfram syndrome.


CRISPR corrects genetic defect so cells can normalize blood sugar.
