Wearables such as smartwatches, fitness trackers, or data glasses have become an integral part of our everyday lives. They record health data, monitor your sleep, or calculate your calorie consumption. Researchers from Karlsruhe Institute of Technology (KIT) have developed the open-source platform “OpenEarable.” It integrates a multitude of sensors into wireless earphones with the aim to enhance health measurements and safety applications in medicine, industry, and everyday life. The scientists are currently presenting their platform at Hannover Messe from March 31 to April 4.

Wearable technologies have made significant progress in recent years, but many of the existing systems are either proprietary, i.e. not customizable by others, or their measurement capabilities are limited. With OpenEarable 2.0, a research team headed by Dr. Tobias Röddiger from KIT’s TECO research group moves one step further: The open-source platform for ear-based sensor applications enables developers to create customized software. With a unique combination of sensors, more than 30 physiological parameters can be measured directly at the ear – from heart rate and breathing patterns to fatigue and body temperature. “Our aim was to create an open and high-precision solution for health monitoring that goes far beyond what is possible with today’s commercial wearables,” says Röddiger. “OpenEarable 2.0 provides a platform for researchers and developers that is easily customizable and scalable. This allows them to program the earphones individually for specific requirements.

MicroRNAs (miRNAs) serve as key regulators of enteric nervous system development, orchestrating migration, proliferation, and differentiation of enteric nervous system progenitors.

Aberrant miRNA expression underpins the pathogenesis of several enteric neuropathies, including Hirschsprung’s disease.

A convergence of miRNA activity across distinct enteric neuropathies highlights shared molecular pathways, exemplified by the miR-200 family.

Modulating the expression of miRNAs to influence their associated gene expression networks has therapeutic potential for enteric neuropathies. https://sciencemission.com/MicroRNA-regulation-of-enteric-ne…nd-disease

The enteric nervous system (ENS), an elaborate network of neurons and glia woven through the gastrointestinal tract, is integral for digestive physiology and broader human health. Commensurate with its importance, ENS dysfunction is linked to a range of debilitating gastrointestinal disorders. MicroRNAs (miRNAs), with their pleiotropic roles in post-transcriptional gene regulation, serve as key developmental effectors within the ENS. Herein, we review the regulatory dynamics of miRNAs in ENS ontogeny, showcasing specific miRNAs implicated in both congenital and acquired enteric neuropathies, such as Hirschsprung’s disease (HSCR), achalasia, intestinal neuronal dysplasia (IND), chronic intestinal pseudo-obstruction (CIPO), and slow transit constipation (STC).

Health care providers can use small devices to hover over moles or lesions and immediately check for common skin cancers, such as melanoma and basal cell carcinoma.

The most significant benefit is that health care professionals who do not specialize in dermatology could perform these checks during a routine visit, making early detection easier and quicker.

Skin cancer is the most common form of cancer in the United States, with one in five Americans expected to be affected in their lifetime, according to the City of Hope Cancer Center.

Researchers at Ben-Gurion University of the Negev have developed a machine-learning algorithm that could enhance our understanding of human biology and disease. The new method, Weighted Graph Anomalous Node Detection (WGAND), takes inspiration from social network analysis and is designed to identify proteins with significant roles in various human tissues.

Proteins are essential molecules in our bodies, and they interact with each other in , known as (PPI) networks. Studying these networks helps scientists understand how proteins function and how they contribute to health and disease.

Prof. Esti Yeger-Lotem, Dr. Michael Fire, Dr. Jubran Juman, and Dr. Dima Kagan developed the algorithm to analyze these PPI networks to detect “anomalous” proteins—those that stand out due to their unique pattern of weighted interactions. This implies that the amount of the protein and its protein interactors is greater in that particular network, allowing them to carry out more functions and drive more processes. This also indicates the great importance that these proteins have in a particular network, because the body will not waste energy on their production for no reason.

Individuals who were conceived in colder seasons are more likely to show higher brown adipose tissue activity, increased energy expenditure and a lower body mass index (BMI), and lower fat accumulation around internal organs, compared with those conceived in warmer seasons, suggests a study published in Nature Metabolism. The findings, based on an analysis involving more than 500 participants, indicate a potential role for meteorological conditions influencing human physiology.

Although eating habits and exercise are key indicators of fat loss, exposure to cold and warmth also plays a part. In colder temperatures, the body generates more heat (cold-induced thermogenesis) via brown adipose tissue activity and stores less fat in the form of white adipose tissue than it does in hotter temperatures. However, underlying factors contributing to in brown adipose tissue activity remain poorly understood, particularly in humans.

Takeshi Yoneshiro and colleagues analyzed brown adipose tissue density, activity and thermogenesis in 683 healthy male and female individuals between ages 3 and 78 in Japan, whose parents were exposed to (defined in the study as between 17 October and 15 April) or warm temperatures (between 16 April and 16 October) during the fertilization and birth periods.

Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny chemicals relevant to human health.

Research by Rutgers University-New Brunswick scientists centers on RNA, a nucleic acid that plays a crucial role in most cellular processes. Their work is expected to have applications in the surveillance of environmental chemicals and, ultimately, the diagnosis of critical diseases including neurological and cardiovascular diseases and cancer.

“Imagine that people will go to the hospital and give a sample of cells from their own bodies for regular check-ups,” said Enver Cagri Izgu, an assistant professor in the Department of Chemistry and Chemical Biology in the Rutgers School of Arts and Sciences and the corresponding author of the study.
