Involvement of brain peptide dynamics in the pathology of fatty liver disease

GH–IGF-1 axis and brain peptide in MASLD pathology

2023-11-03

(Press-News.org)

Niigata, Japan – The research group of Professor Kamimura in Niigata University have demonstrated the complementary role of peripheral and central nervous system on GH–IGF-1axis activation to prevent MASLD progression. IGF-1 ameliorates fatty infiltration in the liver. Its release is controlled by GH and GH activation is managed by peripheral or central nervous system. However, the role of this axis in MASLD developmental phase has not been well identified. Our study demonstrated that the GH–IGF-1 axis is significant in inhibiting the progression of MASLD. In addition to the peripheral autonomic nervous system activating gastric ghrelin to release GH, hypothalamic BDNF and CRH are keys in central nervous system for GH expression. “IGF-1 release by the nervous system is the key factor in maintaining the pathological homeostasis of MASLD, suggesting its therapeutic potential.” says Prof. Kamimura.

How to measure improvement in Long COVID identified in an international consensus study

2023-11-03

Researchers have reached an agreement on how best to measure the severity and impact of Long COVID by identifying a “Core Outcome Measure Set” (COMS). The research, published in Lancet Respiratory Medicine is co-led by the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London and in collaboration with the World Health Organisation (WHO). COMS are designed to help researchers and clinicians measure symptoms and impacts of disorders such as Long COVID in the same way, which optimises how data can be compared and summarised. Researchers say this will accelerate the understanding of, and the development ...

Human insulin less temperature-sensitive than previously thought

2023-11-03

A new Cochrane review has found that insulin can be kept at room temperature for months without losing potency, offering hope to people living with diabetes in regions with limited access to healthcare or stable powered refrigeration. This affects millions of people living in low- and middle-income countries, particularly in rural areas, as well as people whose lives have been disrupted by conflict or natural disasters. Human insulin is a hormone produced by the body that helps turn food into energy and controls blood sugar levels. People with diabetes cannot make enough insulin and those with type 1 diabetes have to inject insulin several times a day, typically before every meal. ...

Study reveals untapped potential to increase eye donations needed for sight-restoring surgeries

2023-11-03

EMBARGOED: Not for Release Until 00:01 AM (UK Time) on Friday 3 November 2023 New research highlights the need for routine discussions about eye donation in end-of-life care clinical settings Less than four per cent of eligible patients in end-of-life care settings were asked to consider eye donation Patients had positive views about eye donation, but most did not know it could be an option for them Staff need training and guidance to support discussing eye donation with patients A new study has found there is significant scope to increase the number of eye donations from patients cared for in hospice and palliative care settings - donations which are desperately needed for ...

Penn Medicine researchers develop gene editing approaches for phenylketonuria treatment

2023-11-02

PHILADELPHIA— Phenylketonuria (PKU) is a rare newborn genetic disease that impacts between 1 in 10,000 to 1 in 20,000 people, depending on the individuals’ genetic ancestry. PKU causes an amino acid—called phenylalanine (Phe)—to build up in the bloodstream. Uncontrolled PKU can lead to intellectual disability, psychiatric issues, and seizures. While current therapies can partially improve outcomes, they require meticulous, lifelong compliance that is very difficult for most patients. ...

Mount Sinai researchers detail mechanism of a key protein implicated in age-related brain dysfunction

2023-11-02

Mount Sinai researchers have shed valuable light on the mechanism of a key protein that regulates the plasticity and function of the hippocampus, a key brain region involved in memory and learning, and that decreases with age in mice. The team’s findings, published in Molecular Psychiatry, could pave the way for a better understanding of how the protein, known as tissue inhibitor of metalloproteinases 2 (TIMP2), could potentially be targeted in age-related disorders like Alzheimer’s disease to help restore ...

UH researcher tackles mysterious Z-RNA structure and its potential connection to diseases

2023-11-02

University of Houston Assistant Professor of Biology and Biochemistry Quentin Vicens has been awarded a $1.2 million grant from the National Institute of General Medical Sciences to unravel the mystery of Z-RNA – an enigmatic RNA structure within our cells that plays a critical role in immune response. This work is in collaboration with the laboratory of Beat Vögeli, associate professor at the University of Colorado and co-recipient of the award. Vicens, Vögeli and their research teams are on a mission to understand how Z-RNA forms, how often it appears in our genetic material and what it means for ...

Different antibiotics’ effects on gut microbes may impact hypertensive organ damage

Are sodium-glucose cotransporter-2 inhibitors safe for patients with diabetes and cancer?

2023-11-02

Highlights Investigators found that in patients with diabetes and cancer, sodium glucose cotransporter-2 inhibitors were associated with a higher risk of diabetic ketoacidosis and fracture and a lower risk of acute kidney injury and urinary tract infection compared with glucagon-like peptide 1 receptor agonists. Results from the study will be presented at ASN Kidney Week 2023, November 1–November 5. Philadelphia, PA (November 2, 2023) — Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have heart- and kidney-related benefits for patients with and without diabetes ...

Wildfire air pollution may increase risks of hospitalization and death among patients on dialysis

2023-11-02

Results from the study will be presented at ASN Kidney Week 2023 November 1–November 5. Philadelphia, PA (November 2, 2023) — In analyses of data from western US states, increases in wildfire-related air pollution around dialysis clinics were linked to higher rates of hospitalizations and deaths among patients.
