Beneficial Effects of the Ketogenic Diet on Nonalcoholic Fatty Liver Disease (NAFLD/MAFLD).

The prevalence of nonalcoholic fatty liver disease (NAFLD) is likely to be approaching 38% of the world's population. It is predicted to become worse and is the main cause of morbidity and mortality due to hepatic pathologies. It is particularly worrying that NAFLD is increasingly diagnosed in children and is closely related, among other conditions, to insulin resistance and metabolic syndrome.

[Ketogenic diet as a trigger for diabetic euglycaemic ketoacidosis in a patient under treatment with iSGLT2].

Euglycaemic diabetic ketoacidosis is a possible adverse effect of selective sodium-glucose cotransporter inhibitors 2 (isGLT2) in patients with diabetes. However, the main scientific societies have recently recommended low or very low carbohydrate diets for the treatment of diabetes, relating the latter with the onset of ketosis. The combination of treatment with these drugs and following this type of diet can be dangerous.

Role of cannabinoid CB2 receptor in the reinforcing actions of ethanol.

This study examines the role of the cannabinoid CB2 receptor (CB2 r) on the vulnerability to ethanol consumption. The time-related and dose-response effects of ethanol on rectal temperature, handling-induced convulsions (HIC) and blood ethanol concentrations were evaluated in CB2 KO and wild-type (WT) mice. The reinforcing properties of ethanol were evaluated in conditioned place preference (CPP), preference and voluntary ethanol consumption and oral ethanol self-administration.

Decreased cocaine motor sensitization and self-administration in mice overexpressing cannabinoid CB₂ receptors.

The potential involvement of the cannabinoid CB₂ receptors (CB₂r) in the adaptive responses induced by cocaine was studied in transgenic mice overexpressing the CB₂r (CB₂xP) and in wild-type (WT) littermates. For this purpose, the acute and sensitized locomotor responses to cocaine, conditioned place preference, and cocaine intravenous self-administration were evaluated. In addition, we assessed whether CB₂r were localized in neurons and/or astrocytes, and whether they colocalized with dopamine D1 and D2 receptors (D1Dr and D2Dr).

Overexpression of CB2 cannabinoid receptors results in neuroprotection against behavioral and neurochemical alterations induced by intracaudate administration of 6-hydroxydopamine.

The role of CB2 cannabinoid receptors in the behavioral and neurochemical changes induced by intracaudate administration of 6-hydroxydopamine (6-OHDA) was evaluated. 6-OHDA (12 μg/4 μL) or its vehicle was injected in the caudate-putamen (CPu) of mice overexpressing the CB2 cannabinoid receptor (CB2xP) and wild type (WT) mice. Motor impairment, emotional behavior, and cognitive alterations were evaluated.

Lateralized learning and memory effects of vasoactive intestinal peptide infused into the rat hippocampal CA1 area.

The effects of VIP microinjected unilaterally (left or right) and bilaterally (left and right) at a dose of 50 ng into hippocampal CA1 area of male Wistar rats on learning and memory (shuttle-box) were studied. Bilateral VIP microinjections impaired learning and memory, i.e.

Hippocampal asymmetry in exploratory behavior to vasoactive intestinal polypeptide.

The effects of vasoactive intestinal polypeptide (VIP) microinjected uni- or bilaterally into the CA1 hippocampal area of male Wistar rats at a dose of 10, 50 and 100 ng on exploratory behavior were examined. VIP microinjected bilaterally at a high dose (100 ng) significantly decreased the horizontal movements, while at low doses (10 and 50 ng) had no effect on the exploratory activity. Microinjections of VIP into the left hippocampal CA1 area at doses 50 and 100 ng suppressed the exploratory activity, while right-side VIP administration at a dose 100 ng significantly increased horizontal movements compared to the respective controls.

Lateralized learning and memory effects of angiotensin II microinjected into the rat CA1 hippocampal area.

The effects of angiotensin II (ANG II) microinjected unilaterally (left or right) and bilaterally (left and right) at a dose of 0.5 microg (0.5 nmol) into the CA1 hippocampal area of male Sprague Dowley rats on learning and memory (shuttle box) were studied.
