Long-Term Implicit Epigenetic Stress Information in the Enteric Nervous System and its Contribution to Developing and Perpetuating IBS.

Psychiatric and mood disorders may play an important role in the development and persistence of irritable bowel syndrome (IBS). Previously, we hypothesized that stress-induced implicit memories may persist throughout life via epigenetic processes in the enteric nervous system (ENS), independent of the central nervous system (CNS). These epigenetic memories in the ENS may contribute to developing and perpetuating IBS.

A Multidisciplinary Hypothesis about Serotonergic Psychedelics. Is it Possible that a Portion of Brain Serotonin Comes From the Gut?

Here we present a complex hypothesis about the psychosomatic mechanism of serotonergic psychedelics. Serotonergic psychedelics affect gut microbes that produce a temporary increase of 5-HT by their host enterochromaffin cells (ECs). This increased 5-HT production-which is taken up and distributed by platelets-may work as a hormone-like regulatory signal that could influence membrane permeability in the host organs and tissues and in the brain.

Non-pharmacological treatment in difficult-to-treat rheumatoid arthritis.

Although the management of rheumatoid arthritis (RA) has improved remarkably with new pharmacological therapies, there is still a significant part of patients not reaching treatment goals. Difficult-to-treat RA (D2TRA) is a complex entity involving several factors apart from persistent inflammation, thereafter requiring a holistic management approach. As pharmacological treatment options are often limited in D2TRA, the need for non-pharmacological treatments (NPT) is even more pronounced.

An Experimental Investigation of Ultraweak Photon Emission from Adult Murine Neural Stem Cells.

Neurons like other living cells may have ultraweak photon emission (UPE) during neuronal activity. This study is aimed to evaluate UPE from neural stem cells (NSC) during their serial passaging and differentiation. We also investigate whether the addition of silver nanoparticles (AgNPs) or enhancement of UPE (by AgNPs or mirror) affect the differentiation of NSC.

Classic psychedelics: the special role of the visual system.

Here, we briefly overview the various aspects of classic serotonergic hallucinogens reported by a number of studies. One of the key hypotheses of our paper is that the visual effects of psychedelics might play a key role in resetting fears. Namely, we especially focus on visual processes because they are among the most prominent features of hallucinogen-induced hallucinations.

[Assessment of health related quality of life among epileptic patients in the context of coping strategies and subjective disease perception].

Background And Purpose: Psychosocial condition and life quality of epileptic patients are greatly determined by the existence of the disease-related comorbid disorders, like depression, anxiety, and the subjective disease perception, as well as the neuropsychological consequences of the seizures.It has been examined in patients living with epilepsy how subjective disease perception and coping strategies influence life quality, comorbid depression and the condition of anxiety.

Methods: Study patients were asked to fill in a self-completion questionnaire, which examined their psychosocial condition (HADS, Beck Depression Scale), life quality (Qolie-31), coping strategies (FKV-LIS), and subjective disease perception (IPQ-R), as well as sociodemographic and disease variables.

Mother-newborn separation at birth in hospitals: A possible risk for neurodevelopmental disorders?

In the 20th century, mother-infant separation shortly after birth in hospitals became routine and unique to humans. However, this hospital birth practice is different from the practice in our evolutionary history, where newborn survival depended on close and essentially continuous maternal contact. This time shortly after birth represents a psychophysiologically sensitive or critical period for programming future physiology and behaviour.
