Can Magnoflorine Improve Memory? Immunohistochemical Studies on Parvalbumin Immunoreactive Neurons and Fibers of Mice Hippocampus.

: We assessed the influence of long-term injection of magnoflorine (MAG) on memory acquisition in mice for the first time. : This isoquinoline alkaloid that belongs to the aporphines was isolated from the roots of by centrifugal partition chromatography (CPC) using a biphasic solvent system composed of chloroform: methanol: water in the ratio 4:3:3 (//) with 20 mM of hydrochloric acid and triethylamine, within 64 min. : Our results indicated that long-term injection of MAG 20 mg/kg dose improve the long-term memory acquisition in mice that were evaluated in the passive avoidance (PA) test with no toxicity records.

Cocaine- and Amphetamine-Regulated Transcript (CART) Peptide Is Co-Expressed with Parvalbumin, Neuropeptide Y and Somatostatin in the Claustrum of the Chinchilla.

Although for many years, researchers have been working on understanding the function of the cocaine- and amphetamine-regulated transcript (CART) peptide at the central- and peripheral-nervous-system level, data describing the presence of CART in the claustrum are still missing. Therefore, the aim of the present study was to immunohistochemically investigate the CART expression in the claustrum neurons in chinchillas as well as the CART co-localization with somatostatin (SOM), parvalbumin (PV), and neuropeptide Y (NPY) using double-immunohistochemical staining. The claustrum is divided into two main parts: the dorsal segment (CL), which is located above the rhinal fissure, and the ventral segment (EN), located below the rhinal fissure.

Magnoflorine from Roots-Impact on Hippocampal Neurons in Mice after Short-Term Exposure.

In search of novel potential drug candidates that could be used as treatments or prophylactics for memory impairment, an aporphine alkaloid magnoflorine (MAG) isolated from the root of was proven to exhibit beneficial anti-amnestic properties. Its effects on immunoreactivity to parvalbumin in the mouse hippocampus were assessed together with a study on its safety and concentration in the brain and plasma. For this purpose, four experimental groups were created: the MAG10 group-treated with 10 mg MAG/kg b.

Impact of Thermal Processing on the Composition of Secondary Metabolites of Ginger Rhizome-A Review.

Ginger ( Rosc.) is both a commonly used spice, and an ingredient of various dietary supplements and medications. Its diverse applications result from the range of health benefits that this plant brings thanks to the presence of active compounds (secondary metabolites) in the matrix.

Can Bioactive Compounds in Beetroot/Carrot Juice Have a Neuroprotective Effect? Morphological Studies of Neurons Immunoreactive to Calretinin of the Rat Hippocampus after Exposure to Cadmium.

Cadmium ions (Cd) penetrate the blood-brain barrier and can, among other effects, influence intracellular calcium metabolism, leading to neurodegeneration. In the presented work, we estimated the effect of Cd on the expression of calretinin in the neurons of the rat hippocampus and analyzed the reverse effect of freshly pressed beetroot/carrot juice in this context. In the 12-week lasting experiment, 32 8-week-old male Wistar rats were divided into four experimental groups (n = 8): the control group (C) received pure tap water; the Cd group (Cd)-received Cd dissolved in tap water (5 mg Cd/kg b.

Insulin receptors in the CA1 field of hippocampus and selected blood parameters in diabetic rats fed with bilberry fruit.

Introduction: Bilberry fruit is believed to be a promising factor in the treatment of diabetes mellitus. Chronic hyperglycaemia affects the function of the central nervous system, which may be manifested as changes in hypothalamic insulin signalling.

Material And Methods: Using DPPH and ABTS assays, total phenolic content in bilberry fruit and its antioxidant activities were examined.

Effect of Berberine Isolated from Barberry Species by Centrifugal Partition Chromatography on Memory and the Expression of Parvalbumin in the Mouse Hippocampus Proper.

Neurodegenerative diseases associated with memory disturbances are important health issues occurring due to a prolonged life span. This article presents the results of a study targeting the emergence of a drug candidate with antiamnesic properties. The effect of berberine (BBR), an isoquinoline alkaloid isolated from the overground parts of Pall.

The Evaluation of Pro-Cognitive and Antiamnestic Properties of Berberine and Magnoflorine Isolated from Barberry Species by Centrifugal Partition Chromatography (CPC), in Relation to QSAR Modelling.

Civilization diseases associated with memory disorders are important health problems occurring due to a prolonged life span. The manuscript shows the results of an in vivo study targeting the emergence of two drug candidates with anti-amnestic properties. The preceding quantitative structure-activity relationship (QSAR) studies provided information on the ability of berberine and magnoflorine to cross the blood-brain barrier (BBB).

Co-expression patterns of cocaine- and amphetamine-regulated transcript (CART) with neuropeptides in dorsal root ganglia of the pig.

In the present study the neuronal distribution of CART was evaluated immunohistochemically in porcine dorsal root ganglia (DRGs). In co-localization studies the co-expression patterns of CART with SP, CGRP, galanin, CALB and LENK were investigated by means of triple immunohistochemical stainings. In porcine DRGs, the expression of CART was found in approximately 5% of primary sensory neurons.
