In the last years important advances have been made in the development of drugs for the treatment of alcohol addiction. Acamprosate (calcium bis-acetylhomotaurine) is one of the better established drugs in this field on the European market. This review focuses first on the pharmacokinetics of acamprosate. The published data and the recent advances in our knowledge on the mechanisms involved in the intestinal absorption and elimination of this drug are summarized. The importance of pharmacokinetics for the proper clinical use of acamprosate is highlighted. The anti-relapse as well as the well-known effects of acamprosate on ethanol intake are discussed. The recent experiments in animal models of conditioned withdrawal are reviewed. These experiments, explored for the first time the anticraving effect of the drug. Finally, the proposed hypotheses on the neuropharmacological mechanism of action of acamprosate are discussed. The discussion deals with the relative importance of various hypotheses as well as with the recent experiments that support them. It is pointed out that further research is necessary in order to clearly understand the mode of action of acamprosate as well as the neurobiological mechanisms involved in alcohol dependence.

Membrane fusion is central to fundamental cellular processes such as exocytosis, when an intracellular machinery fuses membrane-enclosed vesicles to the plasma membrane for contents release. The core machinery components are the SNARE proteins. SNARE complexation pulls the membranes together, but the fusion mechanism remains unclear.

Translocation across barriers and through constrictions is a mechanism that is often used in vivo for transporting material between compartments. A specific example is apicomplexan parasites invading host cells through the tight junction that acts as a pore, and a similar barrier crossing is involved in drug delivery using lipid vesicles penetrating intact skin. Here, we use triangulated membranes and energy minimization to study the translocation of vesicles through pores with fixed radii.

Plants possess remarkably durable resistance against non-adapted pathogens in nature. However, the molecular mechanisms underlying this resistance remain poorly understood, and it is unclear how the resistance is maintained without coevolution between hosts and the non-adapted pathogens. In this study, we used Phytophthora sojae (Ps), a non-adapted pathogen of N.

Background: Ovarian cancer (OC), particularly high-grade serous ovarian carcinoma (HGSOC), is the leading cause of mortality from gynecological malignancies worldwide. Despite the initial effectiveness of treatment, acquired resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) represents a major challenge for the clinical management of HGSOC, highlighting the necessity for the development of novel therapeutic strategies. This study investigated the role of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3), a pivotal regulator of glycolysis, in PARPi resistance and explored its potential as a therapeutic target to overcome PARPi resistance.

Fluoride (F), as a natural element found in a wide range of sources such as water and certain foods, has been proven to be beneficial in preventing dental caries, but concerns have been raised regarding its potential deleterious effects on overall health. Sodium fluoride (NaF), another form of F, has the ability to accumulate in reproductive organs and interfere with hormonal regulation and oxidative stress pathways, contributing to reproductive toxicity. While the exact mechanisms of F-induced reproductive toxicity are not fully understood, this review aims to elucidate the mechanisms involved in testicular and ovarian injury.
