NIH researchers identify new genetic disorder that affects brain, craniofacial skeleton

Researchers at the National Institutes of Health have discovered a new genetic disorder characterized by developmental delays and malformations of the brain, heart and facial features. Named linkage-specific-deubiquitylation-deficiency-induced embryonic defects syndrome (LINKED), it is caused by a mutated version of the OTUD5 gene, which interferes with key molecular steps in embryo development.

Obesity – overlooked epidemic of the XXIst century

Nowadays, the fashion trends and cosmetics industry promote fitness and “perfect” body types. Strict following of these “recommendations” may have harmful consequences. Social media do not help, promoting standards – to stay healthy and beautiful, measured in clothing sizes. Usually, there is no room for being “just average”. A larger […]

Study reveals links between fatty liver disease, liver cancer

The United States is facing an epidemic of liver disease linked to obesity. Cases of nonalcoholic fatty liver have more than doubled in the past two decades, now affecting around one-quarter of the country’s population. The condition leads to inflammation and scarring in the liver, similar to that caused by […]

Discovery could lead to more precise way to treat symptoms of advanced Parkinson’s disease

University of Alberta researchers have discovered a potential biomarker—the response of a particular reflex in the body dubbed the Hoffmann reflex—that would help surgeons deliver deep brain stimulation (DBS) more precisely and effectively to patients with advanced Parkinson’s disease. The work, led by U of A neurosurgeon Tejas Sankar, was recently published in […]

STRANGE COLON DISCOVERY EXPLAINS RACIAL DISPARITIES IN COLORECTAL CANCER

The colons of African Americans and people of European descent age differently, new research reveals, helping explain racial disparities in colorectal cancer – cancer that killed beloved “Black Panther” star Chadwick Boseman at only 43. Scientists led by UVA Health’s Dr Li Li and Graham Casey, along with Matt Devall […]

AI-Based Urine Test Diagnoses Prostate Cancer with Almost 100% Accuracy

Although prostate cancer is one the most common types of malignancy in men, diagnosis is typically made on the basis of the Prostate-specific antigen (PSA), with an accuracy as low as 30%. Given how unreliable PSA-based testing can often be, many patients require invasive biopsy which often leaves them with […]

Proteomic analysis reveals when and how which proteins are degraded in cancer cells by Autophagy pathways

A fundamental process by which cellular components are degraded is Autophagy. Defects in Autophagy pathways are strongly associated with multiple human diseases, including neurodegenerative disorders and cancer. Despite their importance, to date, a comprehensive characterization of the extent and selectivity for Autophagic degrades has remained largely uncharacterized. Researchers at Karolinska […]

New discovery in breast cancer treatment

Liverpool cancer researchers have contributed to important new findings of the positive role of androgens in breast cancer treatment, with immediate implications for women with oestrogen receptor-positive (ER-positive) advanced disease. ER-positive breast cancer is the most common type of breast cancer diagnosed today, accounting for around 75 out of every […]

Fatty acid may help combat multiple sclerosis

The abnormal immune system response that causes multiple sclerosis (MS) by attacking and damaging the central nervous system can be triggered by the lack of a specific fatty acid in fat tissue, according to a new Yale study. The finding suggests that dietary change might help treat some people with […]

An Example of High Dose Fisetin Exhibiting Senolytic Effects in Mice

Fisetin is perhaps the most intriguing of the first generation senolytic compounds, those capable of selectively destroying senescent cells in old tissues and thus producing rejuvenation to a meaningful degree. Senolytics have been demonstrated in animal studies to reverse many age-related conditions to a greater degree than any other approaches. […]

The immune system mounts a lasting defense after recovery from COVID-19

As the number of people who have fought off SARS-CoV-2 climbs ever higher, a critical question has grown in importance: How long will their immunity to the novel coronavirus last? A new Rockefeller study offers an encouraging answer, suggesting that those who recover from COVID-19 are protected against the virus […]

Personalized Brain Stimulation Alleviates Severe Depression Symptoms

Targeted neuromodulation tailored to individual patients’ distinctive symptoms is an increasingly common way of correcting misfiring brain circuits in people with epilepsy or Parkinson’s disease. Now, scientists at UC San Francisco’s Dolby Family Center for Mood Disorders and Weill Institute for Neurosciences have demonstrated a novel personalized neuromodulation approach that – at least in […]

Where do our minds wander? Brain waves can point the way

Anyone who has tried and failed to meditate knows that our minds are rarely still. But where do they roam? New research led by UC Berkeley has come up with a way to track the flow of our internal thought processes and signal whether our minds are focused, fixated or […]

Arterial Stiffening with Age Correlates with Structural Damage to the Brain

Today's open access research paper is a reminder of one of the more direct mechanistic links between vascular aging and brain aging. Blood vessels stiffen with age, becoming progressively worse at the necessary task of contracting and relaxing in response to circumstances. This is in part due to cross-linking in […]

Acute itching in eczema patients linked to environmental allergens

In addition to a skin rash, many eczema sufferers also experience chronic itching, but sometimes that itching can become torturous. Worse, antihistamines — the standard treatment for itching and allergy — often don’t help. New research from Washington University School of Medicine in St. Louis indicates that allergens in the environment often […]

UNH Researchers Discover New Inhibitor Drug Combination for Rare Form of Cancer

Waldenström macroglobulinemia (WM), a rare form of lymphoma, does not have any known cure and only one FDA-approved treatment making it challenging to treat patients. Researchers at the University of New Hampshire took the novel approach of targeting specific cell proteins that control DNA information using inhibitors, or drugs, that […]

Moonshots for the Treatment of Aging: Less Incrementalism, More Ambition

There is far too much incrementalism in the present research and development of therapies to treat aging. Much of the field is engaged in mimicking calorie restriction or repurposing existing drugs that were found to increase mouse life span by a few percentage points. This will not meaningfully change the […]

Why cancer cells waste so much energy

In the 1920s, German chemist Otto Warburg discovered that cancer cells don’t metabolize sugar the same way that healthy cells usually do. Since then, scientists have tried to figure out why cancer cells use this alternative pathway, which is much less efficient. MIT biologists have now found a possible answer […]

Artificial intelligence tool for reading MRI scans could transform prostate cancer surgery and treatment

Researchers at the Center for Computational Imaging and Personalized Diagnostics (CCIPD) at Case Western Reserve University have preliminarily validated an artificial intelligence (AI) tool to predict how likely the disease is to recur following surgical treatment for prostate cancer. The tool, called RadClip, uses AI algorithms to examine a variety of data, […]

Frail Older Individuals Exhibit a Worse Response to Vaccination

Frailty is usually accompanied by greater immune dysfunction, given that chronic inflammation is a strong component of both immune aging and the various dysfunctions of frailty. Thus frail individuals exhibit a worse response to vaccinations intended to prevent infectious disease. This is unfortunate, as this is the population in greatest […]
