Membrane nanotubes are ancient machinery for cell-to-cell communication and transport. Their interference with the immune system.

Nanotubular connections between mammalian cell types came into the focus only two decades ago, when "live cell super-resolution imaging" was introduced. Observations of these long-time overlooked structures led to understanding mechanisms of their growth/withdrawal and exploring some key genetic and signaling factors behind their formation. Unbelievable level of multiple supportive collaboration between tumor cells undergoing cytotoxic chemotherapy, cross-feeding" between independent bacterial strains or "cross-dressing" collaboration of immune cells promoting cellular immune response, all via nanotubes, have been explored recently.

Association of clozapine-related metabolic disturbances with CYP3A4 expression in patients with schizophrenia.

Clozapine is effective in treatment-resistant schizophrenia; however, adverse effects often result in discontinuation of clozapine therapy. Many of the side-effects are associated with pharmacokinetic variations; therefore, the expression of major clozapine-metabolizing enzymes (CYP1A2, CYP3A4) in patients may predict development of adverse effects. In patients with schizophrenia (N = 96), development of clozapine concentration-dependent metabolic side-effects was found to be associated with pharmacokinetic variability related to CYP3A4 but not to CYP1A2 expression.

Procognitive profiling of a serotonin 5-HT receptor antagonist in a complex model system in rats: A novel translational approach for clinical prediction.

Introduction: The serial clinical failures of novel cognitive enhancer candidates point out the lack of predictive power in the preceding animal experimentation. For a more predictive profiling of putative procognitive drugs in rodents, we recently elaborated a methodical approach which consists of three fundamental steps: 1. teaching various learning tasks representing different cognitive domains to the same cohort of animals with the aim to create a population with 'widespread knowledge'.

Development and Validation of an LC-MS-MS Method for the Quantification of Cyanate in Rat Plasma and Its Application to Toxicokinetic Bioanalysis.

Lactobacillus salivarius BP121 prevents cisplatin‑induced acute kidney injury by inhibition of uremic toxins such as indoxyl sulfate and p‑cresol sulfate via alleviating dysbiosis.

The gut microbiota is important for maintaining the integrity of the intestinal barrier, promoting immunological tolerance and carrying out metabolic activities that have not evolved in hosts. Intestinal dysbiosis is associated with chronic kidney disease and probiotic supplementation has been shown to be beneficial. However, it is not known whether gut microorganisms‑specifically, lactic acid bacteria (LAB) can protect against acute kidney injury (AKI).

Buprenorphine to reverse respiratory depression from methadone overdose in opioid-dependent patients: a prospective randomized trial.

Background: Naloxone is the usual drug used in opioid-induced respiratory depression but it has a short half-life, precipitates withdrawal in dependent patients, and thus for persistent reversal of long-acting opioids has to be given by titrated doses and infusions. The partial agonist buprenorphine has a much longer duration of action and causes less severe withdrawal, but still should largely reverse respiratory depression induced by full agonist opioids. We aimed to compare the efficacy/safety of buprenorphine and naloxone in reversing respiratory depression in methadone-poisoned opioid-dependent patients.
