Endogenous Substance or Endogenous Process

Texas Senator Bryan Hughes introduced a bill that would require testing wastewater for mifepristone, raising abortion-rights concerns.

The drugs 'work' but may be working against us long-term

To determine how neuronal circuits encode and drive behavior, it is often necessary to measure and manipulate different aspects of neurochemical signaling in awake animals. Optogenetics and calcium sensors have paved the way for these types of studies, ...

A new generation of treatments addresses the trauma that often underlies addiction

A common food dye turned mice see-through, a "stunning" finding that could revolutionize imaging techniques in medicine.

Self-deprecation, a negative self-assessment used in social interaction, is prevalent in Korean reality TV shows. Traditionally, psychology views self-deprecation as indicative of low self-esteem or related psychological disorders, such as depression or eating disorders.

The quest for a guilt-free sweet fix has led us to erythritol and xylitol, those sugar substitutes once hailed as the saviors of our waistlines and blood sugar levels. But hold on to your sugar-free desserts. The latest research suggests that these sweet stand-ins might be doing more than just keeping the calories at bay—they could be inviting a one-way ticket to heart disease. Could this really be true?

Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.

Although nutrition has made significant advances in recent years—such as recognizing the harm caused by trans fats—it is surprising that, even within the academic field, there is still ongoing debate about the most efficient diet. Spoiler alert: any of them can work as long as a diet aligns with your preferences and allows for greater consistency.

Many plans are in preparation to land robotic missions on the surface of the Moon, which will pave the way to return humans to the lunar surface and set the stage for an ongoing human presence. Artemis is a NASA-led international effort to return humans ...

Intranasal oxytocin appears to improve social functioning and quality of life in individuals with autism spectrum disorder, results of a randomized control trial show.

Breast cancer is the most common malignancy in women, posing a serious threat to female health. Due to the high inter- and intra-tumoral heterogeneity of breast cancer, clinical treatment and prognosis can vary greatly in patients.

Extracytoplasmic function sigma factors (ECFs) have been successfully used for constructing predictable artificial gene circuits in bacteria like Escherichia coli, but their transferability between species within the same phylum remained unknown.

Tomato (Solanum lycopersicum L.) is the most widely cultivated and consumed horticultural crop. At present, saline-alkali is an important abiotic stress source that affects tomato production. Exogenous methyl jasmonate (MeJA) can enhance the resistance of tomatoes to various stresses, but its exact mechanism is still unclear.

Proferroptotic activity of 7-dehydrocholesterol reductase is shown along with an unexpected prosurvival function of its substrate, 7-dehydrocholesterol, indicating a cell-intrinsic mechanism that could be used by cancer cells to protect phospholipids from oxidative damage and escape ferroptosis.

The moon's evolutionary history is divided into three distinct phases based on the temporal interplay of exogenic and endogenic processes in altering the moon. These phases are defined as Eon-level time scale units, which provide insights into the temporal dynamics of lunar evolution:

Sharon K. Inouye, MD, MPH, editor in chief of JAMA Internal Medicine, discusses five of the journal's most impactful studies from 2023 and the take-home messages for internists and their colleagues.

A review in Fruit Research by researchers from Henan Agricultural University, China, explores the state of art of research on jujube witches' broom ("Zaofeng") disease, a fruit tree disease associated with phytoplasma.

The ornithine decarboxylase inhibitor α-difluoromethylornithine, used to treat African sleeping sickness and unwanted hair growth, may also protect β cells of people with new-onset type 1 diabetes.
