[PMID: 34542833 DOI: 10.1007/s12017-021-08690-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 09/13/2021] [Indexed: 10/20/2022]
Abstract
Mainly found in brussels sprouts, broccoli, and black mustard seeds, sinigrin (2-propenyl glucosinolate) has enjoyed some attention currently for its effects on health and disease prevention. The present research design is aimed at investigating the effects of sinigrin on inflammation, oxidative stress (OS) and memory. Randomly, six groups of male Wistar rats were categorized into the control and experimental groups. The experimental groups were treated with sinigrin (10 and 20 mg/kg, orally). The control positive group was given the pentylenetetrazole (PTZ) treatment and the control negative one was given normal saline. All groups were kindled by the sub-threshold dose (35 mg/kg, i.p.) of PTZ for 12 times in one month. When the kindling procedure was done, the seizure behaviors and the behavioral function were evaluated. For cognitive parameters, the shuttle box test was employed. When the experiment was terminated, the rats were euthanized and their blood serum as well as brain samples were isolated for respective measuring of OS and gene expression parameters. The treatment with sinigrin significantly delayed the appearance of the seizure symptoms in comparison to that of the PTZ group. It also significantly increased the memory parameters like retention latency and the total time having been spent in the light compartment in the epileptic rats. In addition, sinigrin increased the superoxide dismutase and catalase levels. Treatment with sinigrin suppressed the Il1b and Nlrp3 gene expression at hippocampal level. In sum, sinigrin prevents inflammation, OS and memory impairment against the PTZ-kindling epilepsy in rats.

Rapamycin alleviates memory deficit against pentylenetetrazole-induced neural toxicity in Wistar male rats. Mol Biol Rep 2021; 48:5083-5091. [PMID: 34165769 DOI: 10.1007/s11033-021-06504-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 06/17/2021] [Indexed: 10/21/2022]
Abstract
Numerous studies have reported that epilepsy causes memory deficits. The present study was aimed at studying the effect of rapamycin against the memory deficiency of the pentylenetetrazole (PTZ)-kindled animal model of epilepsy. In the present experiment, we randomly chose thirty male rats from the species of Wistar and categorized them in groups of control and experiment (6 for each group). The groups of experiment received the injection of rapamycin (0.5, 1 and 2 mg/kg) intraperitoneally (i.p.) and the group of control received normal saline (0.9%) treatment. Through the PTZ's sub-threshold dose (35 mg kg-1, i.p.), all groups were kindled 12 times. Passive avoidance test (PAT) was used for gauging the memory function and the seizure behaviors after the kindling procedure. The rodents were sacrificed at the end of the trial and their brains were scooped for measuring the expression of Gabra1 and Pras40 genes. Statistical analysis unveiled that rapamycin delayed the kindling development and the onset of seizures which are tonic-clonic. Moreover, the administration of rapamycin significantly prevented memory dysfunction in epileptic rats. Finally, it was shown that rapamycin resulted in an increase in the expression levels of Gabra1 and Pras40 genes at the brain tissues. The current research design indicated that rapamycin has beneficial effects for the prevention of memory impairment against PTZ-kindling epilepsy in rats. Such promising outcomes could be attributed to its impact on the Gabra1 and Pras40 genes.

Abstract
Abstract
Background
Some chemotherapy drugs such cyclophosphamide (CP) has destructive effects on hematopoietic cells in the bone marrow tissue. Due to antioxidant and anti-inflammatory features, medicinal herbs have protective effects on the bone marrow tissue. The aim of this experimental study is to examine the protective effects of Rubus fruticosus L. extract (RF) on blood parameters in male rats treated with CP.
Methods
In this experimental study, 35 male Wistar rats (220–250 g) were randomly divided into 5 groups (n = 7): Control (0.5 mL normal saline), CP (15 mg/kg), positive control (RF per se 200 mg/kg), treatment 1 (CP 15 mg/kg + RF 100 mg/kg), and treatment 2 (CP 15 mg/kg + RF 200 mg/kg). All drugs and extracts were given intraperitoneally for 15 consecutive days. At the end of the intervention, all animals were euthanized and their blood samples were collected by cardiac puncture in anti-coagulant tubes for blood parameters evaluation.
Results
The data analysis showed that CP has decreased significantly in RBC, WBC, Platelets number, hemoglobin and hematocrit in rats (p < 0.05). RF could protect hematopoiesis in CP-induced rats (p < 0.05).
Conclusion
The use of RF can protect the blood hematopoietic tissue in bone marrow and prevent CP toxic effects.

Abstract
Introduction: Diabetic neuropathy (DN) is one of the major complications arising from hyperglycaemia in diabetic patients. In recent years polyphenols present in plants have gained attention to treat DN. The main advantages associated with them are their action via different molecular pathways to manage DN and their safety. However, they failed to gain clinical attention due to challenges associated with their formulation development such as lipophilicity,poor bioavailability, rapid systemic elimination, and enzymatic degradation.Area covered: This article includes different polyphenols that have shown their potential against DN in preclinical studies and the research carried out towards development of their nanoformulations in order to overcome aforementioned issues.Expert opinion: In this review various polyphenol based nanoformulations such as nanospheres, self-nanoemulsifying drug delivery systems, niosomes, electrospun nanofibers, metallic nanoparticles explored exclusively to treat DN are discussed. However, the literature available related to polyphenol based nanoformulations to treat DN is limited. Moreover, these experiments are limited to preclinical studies. Hence, more focus is required towards development of nanoformulations using simple and single step process as well as inexpensive and non-toxic excipients so that a stable, scalable, reproducible and non-toxic formulation could be achieved and clinical trials could be initiated.

J Food Biochem 2020; 45:e13427. [PMID: 32779754 DOI: 10.1111/jfbc.13427] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 07/16/2020] [Accepted: 07/17/2020] [Indexed: 12/21/2022]
Abstract
The effect of Editan (Lasianthera africana) leaf inclusive diet (ELD) on neuronal cholinesterases (ChE), ecto-5'-nucleotidase, and endogenous antioxidant indices [superoxide dismutase (SOD), catalase (CAT), glutathione (GSH)] in cyclophosphamide (CYP)-administered albino rats were investigated. Thirty male albino Wistar rats were dissevered appropriately (n = 6). Group I-normal control rats (NC), II-untreated CYP-administered rats, III-CYP-administered rats pre-treated with donepezil (DON), group IV-CYP-administered rats fed ELD, and V-normal rats fed with ELD for 21 days. Results obtained revealed that CYP-administered rats significantly (p < .05) had elevated activities of ChE, ecto-5'-nucleotidase and thiobarbituric acid reactive species (TBARS), and concomitantly decreased in the antioxidant indices. However, pre-treatment with either DON or ELD reversed these effects, thereby eliciting a therapeutic effect which could be linked to the rich polyphenol and alkaloid constituents in the studied leaf, and could be responsible for the potential ethnopharmacological actions of the ELD in the management neurodegeneration. PRACTICAL APPLICATIONS: Currently, the use of plant-food to control diseased conditions due to their phytochemicals has been explored, most especially, the indigenous edible vegetables from the Southwestern part of Nigeria. "Editan" leafy vegetable scientifically known as Lasianthera africana is commonly used in soups preparation and in folklore for the management of some human ailments. Editan leaf is a rich source of alkaloid and phenolic compounds, which could be used to treat and or manage neurological diseases. This study, therefore, unravels the fact that the studied leafy vegetable possesses therapeutic potentials toward the management of neurological disorders.

Abstract
Type 2 diabetes mellitus is associated with complications such as Alzheimer disease (AD). Tropical eggplant (Solanum gilo, Solanum kumba, and Solanum aethiopicum) fruits have been extensively used for the treatment of different ailments. This study assesses the effect of an eggplant supplemented-diet on purinergic, monoaminergic, and cholinergic enzyme systems in diabetic male rats, besides determining the presence of alkaloids using GC-MS chromatography. Results from this study show that eggplant fruit diet modulates the activities of the enzymes in purinergic, monoaminergic, and cholinergic enzyme systems associated with AD-like symptoms. Solanum kumba-supplemented diet significantly (p < 0.05) reduced enzyme activities better than S. gilo and S. aethiopicum, which could be due to its rich phytochemical constituents. In conclusion, eggplant fruits could serve as a holistic measure in the prevention of diabetes-related complications such as neurodegenerative disease. PRACTICAL APPLICATIONS: The therapeutic management of diabetes fails to holistically address inflammatory response which likely contributes to type 2 diabetes mellitus (T2DM) occurrence by causing insulin resistance; this, in turn, is intensified in the presence of hyperglycemia to promote long-term complications such as neurodegenerative disorders. The health benefit of a tropical eggplant fruit diet inform a nutritional and therapeutic approach for the prevention and treatment of T2DM and its associated complications such as neurodegenerative disorders has been proved. The eggplant fruit-supplemented diet, which is cost-effective with little or no side effect, could substantially increase the antioxidant status and also modulate the activities of neuronal enzymes in a diabetic model with dementia, as well as Alzheimer's-like symptoms. This study, therefore, revealed more of the benefits of tropical eggplant fruits vis-à-vis their management in hyperglycemia-mediated neurodegeneration.

Abstract
This research work aimed to obtain blackberry pulp powder by spray drying and, by an experimental design, evaluated the effect of inlet air temperature (100-150 °C) and blackberry pulp solids:arrowroot starch/gum arabic solids ratio of 1:0.5-1:2 on the physicochemical properties of the powders. Arrowroot starch and gum arabic present glass transition temperature (Tg) values above 100 °C; hence it was possible to employ them as carriers in blackberry pulp spray drying in order to increase Tg of the system. Powder yield and solubility increased with increasing blackberry pulp solids:arrowroot starch/gum arabic solids ratio of 1:0.5-1:2, whereas hygroscopicity decreased. Yield, solubility and hygroscopicity of the powders increased and water activity decreased, with increasing inlet air temperature. The powders presented low moisture content and water activity. Temperature of 143 °C and blackberry pulp solids:arrowroot starch/gum arabic solids ratio of 1:1.78 were the optimal conditions to obtain high yield and blackberry powders that are soluble in water and less hygroscopic.

Abstract
A high-fat diet (HFD) causes deficits in learning and memory by increasing oxidative stress. Antioxidants are known to improve learning and memory. Since Hypericum scabrum (H. scabrum) extract is rich in antioxidants, the aim of this study was to investigate the effects of the administration of H. scabrum extract on passive avoidance learning (PAL), novel object recognition (NOR), and locomotor activity in male rats on a HFD. Fifty-four male Wistar rats (weighing 220 ± 10 g) were divided into the following six groups: (1) Control (standard diet), (2) Ext100 (standard diet supplemented with 100 mg/kg extract once/day), (3) Ext300 (standard diet supplemented with 300 mg/kg extract once/day), (4) HFD (high-fat diet), (5) HFD + Ext100, and (6) HFD + Ext300. Rats in these groups were maintained on their respective diets for 3 months. In the PAL test, the step-through latencies in the retention test (STLr) were significantly higher in the HFD + extract group than in the HFD group. The time spent in the dark compartment (TDC) was significantly lesser and the time spent in exploring the novel object was significantly greater in the HFD + extract group than in the HFD group. In the HFD-fed rats, the activity of catalase had significantly decreased, and level of malondialdehyde had significantly increased; H. scabrum extract administration significantly reversed these changes. In conclusion, these results suggested that the administration of H. scabrum extract and its strong antioxidant properties enhanced learning and memory and reversed the memory impairment induced by chronic HFD consumption.
