TMS and EEG Pharmacodynamic Effects of a Selective Sphingosine-1-Phosphate Subtype 1 Receptor Agonist on Cortical Excitability in Healthy Subjects.

Current anti-epileptic drugs lack efficacy, cause many side effects and one third of all patients are treatment-resistant. Drugs targeting the sphingosine-1-phosphate receptor show potential anti-convulsant effects in animal models and decrease cortical excitability in patients with multiple sclerosis, but available compounds alter lymphocyte trafficking and cause immunosuppression, limiting their clinical anti-epileptic potential. TRV045 is a selective sphingosine-1-phosphate subtype 1 receptor agonist without effects on lymphocyte trafficking, demonstrating efficacy in animal models of epilepsy, with the potential to target abnormal cortical excitability.

Assessment of molecular modulation by multifrequency electromagnetic pulses to preferably eradicate tumorigenic cells.

Physics methods of cancer therapy are extensively used in clinical practice, but they are invasive and often confront undesired side effects. A fully new equipment that allows sustained emission of intense and time-controlled non-ionizing multifrequency electromagnetic pulse (MEMP), has been applied to eukaryotic cells in culture. The equipment discriminates the overall electronegative charge of the cell cultures, and its subsequent proportional emission may thereby become higher and lethal to cancer cells of generally high metabolic activity.

The effect of binaural pulse modulation (B.P.M) on brain state in depression and anxiety: a case series.

Objective: In this pilot study a binaural pulse modulator was tested to see if it leads to a change in self-reported measures of distress. This binaural pulse modulator produces two frequencies that combine to create a binaural pulse to stimulate the nervous system through a differential auditory tone presentation and the response of the user can be adjusted to the appropriate target tone for effective treatment use. Each individual calibrated the binaural pulse to increase the level of emotion experienced while imagining an experience with a similar emotional valence or while engaged in a cognitive function while also listening to the sound.

Development of bombesin-tubulysin conjugates using multicomponent chemistry to functionalize both the payload and the homing peptide.

Peptide-drug conjugates (PDCs) have recently gained significant attention for the targeted delivery of anticancer therapeutics, mainly due to their cost-effective and chemically defined production and lower antigenicity compared to ADCs, among other benefits. In this study, we designed and synthesized novel PDCs by conjugating new thiol-functionalized tubulysin analogs (tubugis) to bombesin, a peptide ligand with a relevant role in cancer research. Two tubulysin analogs bearing ready-for-conjugation thiol groups were prepared by an on-resin multicomponent peptide synthesis strategy and subsequently tested for their stand-alone anti-proliferative activity against human cancer cells, which resulted in IC values in the nanomolar range.
