No aspects of pre-conception intuitive eating predicted the likelihood of excess GWG. However, in the total sample, unconditional permission to eat (subscale) was inversely related to total GWG (B = -0.16, p  less then  0.05). Among women with obesity (n = 36), eating for physical rather than emotional reasons (subscale) was inversely related to total GWG (B = -0.47, p  less then  0.05). DISCUSSION Some aspects of intuitive eating during the pre-conception period were related to total GWG, particularly for women with obesity. However, intuitive eating scores did not increase or decrease the likelihood of excess GWG. More research is needed to understand the mechanisms for this association before clinical recommendations can be made. LEVEL OF EVIDENCE Level III (Evidence obtained from well-designed cohort or case-control analytic studies).The term regulatory "convergence" is apparently given many meanings in the field of medical products. Originally defined as a process of making regulatory requirements similar across countries, the term can now mean regulatory similarity of any degree, sometimes mixed with regulatory cooperation of almost any kind among countries. More concretely, the term can refer to regulatory authorities' complete or incomplete adoption of global guidelines, joint review/inspection of the dossiers or facilities with other regulatory authorities, accepting other authority's decision critically or uncritically, or any combination thereof. While the term has introduced a useful notion, the acquired ambiguity is causing a certain confusion in the discussion. This article tries to clarify the term's meanings in different contexts and resolve confusions. By going deeper than "convergence" to identify the elements that matters, the regulatory authorities, inter alia, should be able to formulate a more conscious and effective strategy on global medical product regulations.The article Long-term vigabatrin treatment modifies pentylenetetrazole-induced seizures in mice focused on GABA brain concentration.BACKGROUND Irritable bowel syndrome (IBS) is a chronic condition with recurring gastrointestinal (GI) symptoms altered motility and abdominal pain. As endogenous opioid system participates in pain perception and in the control of GI peristalsis, opioids have been proposed as a promising therapy in IBS. In a previous study, we observed that morphiceptin derivative, P-317 (Dmt-cyclo-(D-Lys-Phe-D-Pro-Asp)-NH2), presents promising features to be applied in IBS. In this project, we tested whether modifications in cyclic morphiceptin-based structure fluorination (compound 1) or peptide bond reduction (compound 2) improve pharmacological effect. METHODS We evaluated tested derivatives in the mouse GI system under physiological (GI transit) and pathophysiological (castor oil diarrhea, stress-induced hypermotility, visceral pain) conditions. RESULTS Both compounds prolonged GI transit. Compound 1 and P-317 inhibited upper GI transit and motility of the colon; compound 2 remained inactive. Compound 1 and P-317 inhibited hypermotility in stressed mice and delayed the acute diarrhea in comparison to control. Only P-317 exerted antinociceptive effect. None of tested derivatives, similar to P-317, affected locomotor activity. CONCLUSIONS Compound 1 is equally effective as P-317 in the mouse GI tract. The peptide bond reduction decreased the activity of compound 2. Fluorination appears to be an efficient way to increase the effects of morphiceptin analogs in the GI tract.BACKGROUND Many neurodegenerative disorders include oxidative stress-mediated pathology. Melatonin and its metabolites act as endogenous reactive oxygen species (ROS) scavengers and antioxidants. N,N'-Disubstituted benzimidazole-2-thiones with extended side chains could exert antioxidant and neuroprotective properties due to structural similarities to melatonin. METHODS The toxicological potential of the compounds was evaluated by monitoring the synaptosomal viability and the levels of reduced glutathione (GSH) in isolated rat brain synaptosomes. The neuroprotective effects were assessed in vitro in a model of 6-hydroxydopamine (6-OHDA)-induced neurotoxicity. The capability to decrease superoxide anion radical and hypochlorite was evaluated by luminol-dependent chemiluminescent assays. RESULTS Compounds 5-7 containing residues of veratraldehyde, vanillin, and syringaldehyde at concentration 250 μM, preserved at the highest degree the synaptosomal viability and GSH levels. Further screening of compounds 5-7 at lower concentrations of 100 μM, 10 μM, and 1 μM, respectively, demonstrated that 6 and 7 do not show any toxicity within this concentration range. In the model of 6-OHDA-induced oxidative stress, 6 revealed concentration-dependent, neuroprotective, and antioxidant activities similar to melatonin. All the three compounds demonstrated ability to decrease the chemiluminescent scavenging index (CL-SI) in the hypochlorite containing system. In the superoxide system, the hydrazones exhibited different effects on the signal. CONCLUSIONS Our studies suggest that the benzimidazole-aldehyde hybrids act as direct ROS scavengers and membranes' stabilizers against free radicals. Thus, they play a role in the antioxidative defense system and have a promising potential as therapeutic neuroprotective agents for the treatment of neurodegenerative disorders.Treatment of congenital cytomegalovirus infection is mandatory in cases with severe systemic and/or neurological involvement. PRI-724 inhibitor However, some patients are paucisymptomatic, with very subtle systemic manifestations and/or minimal brain alterations. Current international guidelines do not clearly state whether these children should be treated, and this decision is not straightforward for clinicians. Of a small series of six infants with congenital cytomegalovirus infection admitted to our neonatal unit between 2015 and 2019, half showed paucisymptomatic neurological manifestations. In these cases, the determination of ß2-microglobulin in cerebrospinal fluid and magnetic resonance imaging aided in the decision-making concerning the therapeutic approach to follow.
