RESUMEN

Stress is described as a noxious stimulus that affects the health of an individual and alters body homeostasis resulting in changes the individual behavioural and metabolic condition. Synthesis of drug from plants has main interest due the significant medicinal values. The recent investigation was designed to examine the pharmacological impacts of Ficus carica leaves extract on stress. In this experiment, the rodents were randomly distributed as (n=6) control rats were kept at standard condition, second group of rats were exposed with different stressors and Third group of rodents was exposed to stress and treated with extract of ficus carica leaves at the dose of 100 mg/kg. Acute behavioural alteration was observed after 7 days and prolonged impact was monitored after the 28 days. The current finding showed that administration of Ficus carica leaves extract produced anxiolytic behaviours and decreased depression like symptoms in CUMS treated rats. It also increased stimulatory, ambulatory, locomotor activity and enhanced spatial working memory and recognition memory in CUMS exposed rats. So, it can be concluded from recent study that leaves of Ficus carica can be utilized as secure drug for curing physiological stress with less side effect profile.

RESUMEN

Niacin had long been understood as an antioxidant. There were reports that high fat diet (HFD) may cause psychological and physical impairments. The present study was aimed to experience the effect of Niacin on % growth rate, cumulative food intake, motor activity and anxiety profile, redox status, 5-HT metabolism and brain histopathology in rats. Rats were administered with Niacin at a dose of 50 mg/ml/kg body weight for 4 weeks following normal diet (ND) and HFD. Behavioral tests were performed after 4 weeks. Animals were sacrificed to collect brain samples. Biochemical, neurochemical and histopathological studies were performed. HFD increased food intake and body weight. The exploratory activity was reduced and anxiety like behavior was observed in HFD treated animals. Activity of antioxidant enzymes was decreased while oxidative stress marker and serotonin metabolism in the brain of rat were increased in HFD treated animals than ND fed rats. Morphology of the brain was also altered by HFD administration. Conversely, Niacin treated animals decreased food intake and % growth rate, increased exploratory activity, produced anxiolytic effects, decreased oxidative stress and increased antioxidant enzyme and 5-HT levels following HFD. Morphology of brain is also normalized by the treatment of Niacin following HFD. In-silico studies showed that Niacin has a potential binding affinity with degradative enzyme of 5-HT i.e. monoamine oxidase (MAO) A and B with an energy of ~ - 4.5 and - 5.0 kcal/mol respectively. In conclusion, the present study showed that Niacin enhanced motor activity, produced anxiolytic effect, and reduced oxidative stress, appetite, growth rate, increased antioxidant enzymes and normalized serotonin system and brain morphology following HFD intake. In-silico studies suggested that increase 5-HT was associated with the binding of MAO with Niacin subsequentially an inhibition of the degradation of monoamine. It is suggested that Niacin has a great antioxidant potential and could be a good therapy for the treatment of HFD induced obesity.

RESUMEN

Alzheimer's disease (AD) is the common type of dementia and is currently incurable. Existing FDA-approved AD drugs may not be effective for everyone, they cannot cure the disease nor stop its progression and their effects diminish over time. Therefore, the present review aimed to explore the role of natural alternatives in the treatment of AD. A systematic search was conducted using Ovid MEDLINE, CINAHL, Cochrane and PubMed databases and reference lists up to November 30, 2021. Only randomized control trials were included and appraised using the National Institute of Health framework. Data analysis showed that herbs like Gingko Biloba, Melissa Officinalis, Salvia officinalis, Ginseng and saffron alone or in combination with curcumin, low-fat diet, NuAD-Trail, and soy lecithin showed significant positive effects on AD. Moreover, combination of natural and pharmaceuticals has far better effects than only allopathic treatment. Thus, different herbal remedies in combination with FDA approved drugs are effective and more promising in treatment of AD.

RESUMEN

BACKGROUND: The current study utilizes in silico molecular docking/molecular dynamics to evaluate the binding affinity of apigenin and safranal with 5HT1AR/5HT2AR, followed by assessment of in vivo effects of these compounds on depressive and anxious behavior. METHODS: The docking between apigenin and safranal and the 5HT1A and 5HT2A receptors was performed utilizing AutoDock Vina software, while MD and protein-lipid molecular dynamics simulations were executed by AMBER16 software. For in vivo analysis, healthy control (HC), disease control (DC), fluoxetine-, and apigenin-safranal-treated rats were tested for changes in depression and anxiety using the forced swim test (FST) and the elevated plus-maze test (EPMT), respectively. RESULTS: The binding affinity estimations identified the superior interacting capacity of apigenin over safranal for 5HT1A/5HT2A receptors over 200 ns MD simulations. Both compounds exhibit oral bioavailability and absorbance. In the rodent model, there was a significant increase in the overall mobility time in the FST, while in the EPMT, there was a decrease in latency and an increase in the number of entries for the treated and HC rats compared with the DC rats, suggesting a reduction in depressive/anxiety symptoms after treatment. CONCLUSIONS: Our analyses suggest apigenin and safranal as prospective medication options to treat depression and anxiety.

RESUMEN

INTRODUCTION: Diabetes mellitus is a chronic metabolic disorder with an increasing prevalence worldwide. Reduction in blood insulin level alters brain function by inducing oxidative stress with changes in dopamine and norepinephrine neurotransmission, ultimately leading to neuropsychological symptoms. The efficacy of currently available psychotropic drugs is not satisfactory. Therefore, this study was conducted to explore the beneficial effects of a combination of the natural herbs, saffron and chamomile, in treating diabetes and its resultant neuropsychological effects using a rodent model of diabetes mellitus. METHOD: The rats were randomly divided in to eight groups (n = 10), healthy control (HC), diabetic control (DC) and six groups of diabetic rats treated with various concentrations and combinations of saffron and chamomile. Diabetic treatment groups individually received methanolic extract and water decoction of chamomile (30 mg/kg) and saffron (10mg/kg) and their combined half doses (saffron 5mg/kg and chamomile 15mg/kg) for two weeks. Open field test (OFT) and forced swim test (FST) were used to measure the anxiolytic and antidepressant effects of herbs, respectively. Finally, biochemical, and neurochemical estimations were made. RESULTS: The present study suggests the therapeutic effects of herbs especially in co-administrated decoction, against diabetes with improved antioxidant profile and enhanced levels of dopamine and norepinephrine. Anxiolytic and antidepressant effects were evident with improvements in the OFT and FST. Examination of the cortex of the diabetic group revealed cellular damage and tangle formation, which indicates advanced stages of dementia. CONCLUSION: This study shows that the use of a combination of saffron and chamomile improves diabetes control and reduces its related psychiatric effects.

RESUMEN

Fungal transformation of a norethisterone (17α-ethynylestra-4-en-17ß-ol-3-one) (1) by using Macrophomina phaseolina and Paecilomyces variotii was studied. A new metabolite, 17α-hydroxymethyl-androst-4-en-11ß-ol-3-one-17ß-acetate (2) with novel changes and a known metabolite, 17α-ethynylestradiol (3) were obtained from 1 by using M. phaseolina and P. variotii, respectively. Based on various spectroscopic techniques, the structures of both metabolites were characterized. The antimicrobial activities of 1-3 were also evaluated. Compound 1 was found to be moderately active against Salmonella paratyphi while 1-3 were almost inactive against other microorganisms.

RESUMEN

Diabetes is a group of metabolic disorder effecting health of wide number of population and cause neuropsychological decline. In the present study, effect of AI leaves extract on neuropsychological behaviors was observed in diabetic rat's model. Rats were divided into 4 groups as control (saline treated healthy rats), positive control (pioglitazone treated diabetic rats), diabetic control (untreated diabetic rats) and AI leaves extract treated diabetic rats. Diabetes was induced by giving 35% fructose for 6 weeks and a single dose of Streptozotocin (40 mg/kg). After 3 weeks of treatment behavioral and biochemical analysis were done. Behavioral results revealed that induction of type 2 diabetes produced anxiety, depression, decreased motor activity and impaired recognition memory in rats. Treatment with AI leaves extract in diabetic rats significantly decreased anxiety, depression, increased motor activity, enhanced recognition memory. Biochemical investigation revealed that AI leaves extract treat diabetes via improving the levels of fasting insulin and HbA1c and a significant decrease in CK and SGPT levels were observed in AI leaves treated diabetic rats. So, AI besides treating diabetes, helps in lowering the risk of co-occurring diabetic diseases and found effective in lowering neuropsychological decline observed in type 2 diabetes.

RESUMEN

Nanotechnology is a field of science that consists of atoms, molecules and supramolecular molecules that create nanoparticles ranging in size from 1-100nm. Silver nanoparticles are widely used that are considered as effective antimicrobial agents. In this paper, the antioxidant activity of biosynthesized SNPs were analyzed by the DPPPH activity, hydrogen peroxide activity, hydroxyl RSA, TAC, TFC; their results confirmed that the phenolic compounds of this plant peels extracts enhanced the antioxidant and antiglycation activity with respect to silver nanoparticles. Biosynthesized nanoparticles of this plant extracts also showed strong zone of inhibition against the different Xanthomas, Pseudomonas and E. coli. This study concluded that biosynthesized nanoparticles of Mukia maderaspatna (M.M) plant peels extracts have the great biological activities i.e. antiglycation, antioxidant and antibacterial. More research is needed to know the exact dose rate and to compare the different dose combination of the plant with the strong antibiotic agents against these bacteria.

RESUMEN

Reserpine (Res)-induced depletion of monoamines and altered neurotransmission and produces oxidative stress. Tryptophan (TRP) regulated the serotonin neurotransmission. Because systemically injected Res induced behavioral deficits and oxidative stress, while, dietary components prevented these adverse effects, we used TRP a pharmacological tool to prevent Res- induced changes in behavior, memory impairments, oxidative stress and regulation of serotonin neurotransmission in rats. Anxiolytic, antidepressant, cognitive functions, lipid peroxidation, antioxidant enzymes serotonin metabolism were studied in Res and vehicle treated animals following administration of 50 and 100 mg/ml/kg of tryptophan. Following administration of TRP [50 and 100mg/ml/kg], Res induced anxiety-and/or depression like behaviors normalized. Res-induced impaired cognitive function and increased acetylcholinesterase activity also improved following administration of TRP at both doses. Res induced increased brains' malondialdehyde (MDA) and decreased antioxidant enzymes activity also normalized by TRP. Res-induced decreased 5-HT metabolism also regulated by administration of TRP at both doses. In conclusion it can be recommended that administration/supplementation of TRP in daily life can aid in battling the anxiety, depression, modulating serotonergic activity and oxidative stress. Study also exhibits the anti-acetylcholinesterase role of TRP which may be possible reason for improved cognition following stress situation.

RESUMEN

The study is aimed to evaluate the protective impact of banana peel extract (BPE) following noise induce behavioral deficits in male mice. Animals were separated into two groups (control and test, 12 in each). Control mice were given drinking water, at the same time test group was given BPE (400 mg/kg; oral administration). Animals have received their respective treatment for 14 days. Mice were subdivided (n=6) into unstressed and stressed groups on day 15. Noise stress was given to the respective group for 4-h. Behavioral activities were monitored 24-h after the 4-h noise stress. Forced-swim-test, Elevated-plus-maze and light-dark-activity-box tests were performed for depression/anxiety-like behaviors respectively. Morris-water-maze assessment was used for memory. After behavioral tests animals were sacrificed and brain was detached for biochemical estimations and histopathological studies. In the present study, BPE produced anxiolytic and antidepressant-like effects and enhanced memory. Activity of antioxidant enzymes increased while levels of AChE and MDA decreased in BPE treated animals. Histopathological alterations induced by noise stress were also normalized by BPE. It is concluded that supplementation/administration of banana peel has preventive effects against anxiety, depression and memory impairment via its strong antioxidant potential following NS.

RESUMEN

Noise has always been an important environmental factor that induces health problems in the general population. Due to ever increasing noise pollution, humans are facing multiple auditory and non-auditory problems including neuropsychiatric disorders. In modern day life it is impossible to avoid noise due to the rapid industrialization of society. Continuous exposure to noise stress creates a disturbance in brain function which may lead to memory disorder. Therefore, it is necessary to find preventive measures to reduce the deleterious effects of noise exposure. Supplementation of taurine, a semi essential amino acid, is reported to alleviate psychiatric disorders. In this study noise-exposed (100 db; 3 h daily for 15 days) rats were supplemented with taurine at a dose of 100 mg/kg for 15 days. Spatial and recognition memory was assessed using the Morris water maze and novel object recognition task, respectively. Results of this study showed a reversal of noise-induced memory impairment in rats. The derangements of catecholaminergic and serotonergic levels in the hippocampus and altered brain antioxidant enzyme activity due to noise exposure were also restored by taurine administration. This study highlights the importance of taurine supplementation to mitigate noise-induced impaired memory via normalizing the neurochemical functions and reducing oxidative stress in rat brain.

RESUMEN

Maltol capped silver nanoparticles (McAgNPs) were synthesized using maltol (3-hydroxy-2-methyl-4-pyrone) as reducing and capping agent. McAgNPs were characterized by Visible and FTIR (Fourier transform infrared) spectroscopy, dynamic light scattering (DLS), and atomic force microscopy (AFM). Bright yellow color McAgNPs showed surface plasmon resonance (SPR) band at 436 nm, spherical shape and the average size between 35 to 50 nm. McAgNPs revealed higher stability against varying storage time, temperature, pH and salt concentrations. McAgNPs were successfully utilized for the selective and highly sensitive colorimetric detection of cysteine (Cys). Addition of Cys in a solution of McAgNPs, resulted a rapid change in color from yellow to orange because of the formation of nanoaggregates as confirmed by Visible/FTIR spectroscopy, DLS, and AFM studies. The estimated limit of detection (0.043 µM) was found to be more sensitive than previously reported other optical methods. The practical applicability of probe was also established by spiking the known concentrations of Cys in biological (blood plasma and urine) and environmental (tap and lake water) samples with significant recovery rates (92-104.6%). Despite being nontoxic to various tested cell lines, McAgNPs demonstrated potent antimicrobial, antibiofilm, and biofilm eradicating activities, thus potentially valuable in diagnostics and/or the synthesis of other nanocomposite material for broader applications.

RESUMEN

The aging process is concerned with oxidative stress and causing malfunction of various organs such as the liver, kidney and heart. Lithium (Li) salts have shown anti-manic, anti-suicidal, and antioxidant properties. The current study is aimed to evaluate the possible inhibitory effects of various doses (10, 20 & 40mg/ml/kg) of Lithium chloride (LiCl) on D-galactose (D-gal)-produced aging model and explore the underlying mechanism. In the study 40 male rats were randomly alienated into 8 groups i.e. saline, LiCl (10, 20 & 40mg/ml/kg), D-gal and D-gal+LiCl (10, 20 & 40 mg/ml/kg). D-gal was given at a dosage of 300mg/ml/kg$ and animals received their respective treatment for 6 weeks [intraperitoneally (I.P), once daily]. After 2 weeks animals were decapitated and organs (liver, kidney, and heart) were removed for antioxidant assays. Blood was also collected for biochemical parameters. LiCl substantially decreased oxidative strain marker and increased enzymatic antioxidants in the liver, kidney, and heart of D-gal treated rats. LiCl also decreased serum alanine aminotransferase (ALT), aspartate transaminase (AST), creatine, urea, CK-MB, triglyceride, cholesterol, low-density lipoprotein (LDL) and increased high-density lipoprotein (HDL) in D-gal treated animals. High dose (80mg/ml/kg) of LiCl observed as the most effective dose against D-gal induced alterations. These finding LiCl inhibits D-gal induced liver, kidney and heart damages via its antioxidant potential.

RESUMEN

Spirulina platensis (blue-green algae) is a nutritional supplement. It constitutes of high content of protein, antioxidants, various phytopigments and possesses neuroprotective activities. Schizophrenia (SZ) is recognized as a neuropsychiatric disorder in humans with a reduced lifespan followed with impairments in social as well as vocational functioning. Major psychotic symptoms of SZ cluster into three categories: positive, negative and cognitive dysfunctions. Dizocilpine recognized as one of the best drugs to mimic full spectrum of SZ can develop an animal model of the disorder. Various antipsychotics are considered as approved treatment therapy for the psychotic symptoms of SZ but they also exert adverse effects. Thus, there is an excessive need for novel treatment(s) with negligible adverse effects. Present study was designed to evaluate the neuroprotective effects of spirulina in ameliorating the psychosis- like symptoms in dizocilpine-induced rat model of SZ. Spirulina was tested at the dose of 180 mg/kg. Results showed that administration of spirulina improved behavioral deficits and combated the oxidative damage evident by a significant reduction in lipid peroxidation and increase in antioxidant level. Thus, from present findings it may be suggested that spirulina can be used as a therapy for preventive or therapeutic measures.

RESUMEN

The current study was designed to determine the outcome of banana fruit pulp (BFP) on repeated noise stress exposure (NSE)-induced behavioral deficits and oxidative stress in male mice. BFP (600mg/kg b.w) was administered orally once daily for 2 weeks prior exposure to noise stress. Mice were exposed to NS for 4 h after administration of BFP for 2 weeks. Control mice were administered drinking water and similar treatment as given to test animals. At the end of the treatment behavioral changes were monitored. Animals were sacrificed following behavioral assessment and the brain and plasma samples were collected for biochemical analysis. Repeated NS-induced behavioral deficits (anxiety and depression), impaired learning and memory and produced oxidative stress. Administration of BFP inhibited NS-induced behavioral deficits (anxiolytic and antidepressant effects) and improved cognitive abilities. Brain lipid per oxidation was also decreased with concomitant increase of antioxidant enzyme activities. Repeated noise stress increased plasma corticosterone levels. A significant decrease of plasma corticosterone was observed on unstressed BFP treated animals while this decrease was comparable in stressed + BFP animals. Decreased levels of acetylcholinesterase in BPF+NS treated animals indicated increased cholinergic function which improves learning and memory. Repeated oral administration of BFP induced cognitive improving ability, anti-stress effect and potentiated antioxidant defence mechanism in both control and NS mice. Thus, it is suggested that dietary supplementation of BFP has a curative effect against NS-induced psychiatric and cognitive related disorders which merits deliberation and additional appraisal.

RESUMEN

This work explored the in-vitro phytochemical contents and antidiabetic activity of crude seeds powder of Persea americana (CSSPa) and their in-vivo biochemical effects on glycated hemoglobin, lipid profile and other parameters in type 2 diabetic rats (fructose-STZ model). There were 2 groups of over night fasted rats, control (normal diet) and diabetic (35% Fructose for 6 weeks followed with injection (i.p.) of streptozotocin (STZ) (40mg/kg bw). Diabetic group was further divided into diabetic control, positive control (pioglitazone 15mg) and test (CSSPa 500mg) groups. After the appropriate treatments in each group for 2 weeks fasting glucose level (FGL), serum lipids, insulin, alanine aminotransferase (ALT), creatine Kinase (CK) & uric acid were determined. CSPPa showed presence of alkaloids, flavonoids, phenols etc and potent antidiabetic activity with IC50 13.23±0.76µM. CSPPa treatment showed a significant (p<0.01) decline in lipid profile, while HDL showed significant increase (p<0.01) in test group as compared with positive and diabetic control groups. The serum ALT, CK, uric acid, bilirubin & fasting glucose (fbg) showed significant improvements in test group (p<0.01). Coronary risk index (CRI), Fasting insulin resistance index (FIRI), Percent glycemic change (PGC) and HbA1c values also significantly (p<0.01) improved.

RESUMEN

This study was designed to investigate the role of enriched environment in preventing and/or reducing the neurobehavioral deficits produced after nicotine administration in albino Wistar rats. Equal numbers of rat in two groups were either placed in social environment (control group) or social along with physically enriched environment for four weeks before the administration of nicotine. Exposure to different environmental conditions was followed by the intraperitoneal injection of nicotine at the dose of 0.6 mg/kg for seven consecutive days during which addictive behavior was monitored using conditioned placed preference paradigm. Behavioral responses to locomotor activity, anxiety and retention of short term memory were investigated in control and nicotine injected groups exposed to different environments. Results of this study showed that the rats pre-exposed to physical along with social enrichment exhibited a decrease in drug seeking behavior, hyper locomotion, anxiogenic effects along with improvement of working memory as compared to control and nicotine injected groups that were kept in social environment alone. This behavioral study suggests that the exposure to physical enrichment along with socialization in young age can later reduce the chances of compulsive dependence on nicotine and related neurobehavioral deficits.

RESUMEN

Schizophrenia (SZ) is categorized as neuropsychiatric disorder with reduced lifespan and significant impairments in social and vocational functioning. One of the best proposed pharmacological animal models is dizocilpine, as it can mimic the full spectrum of schizophrenic disorder including positive and negative symptoms along with cognitive deficits. Dizocilpine is N-methyl-D-aspartate (NMDA) receptor antagonist known to induce hyper-locomotion and stereotyped behavior in rodents. Present study was designed to develop an animal model of SZ via intraperitoneal administration of dizocilpine in rats (100-150g) at a dose of 0.3 mg/kg for eight days. For the evaluation of positive symptoms, hyperlocomotor behavior was monitored. Negative symptoms were assessed by sucrose preference test (SPT) and social interaction test (SIT). Moreover, Cognitive deficits were evaluated by novel object recognition test (NORT). After behavioral assessments animals were decapitated for further evaluation of biochemical and neurochemical estimations. Present findings revealed that dizocilpine injected rats exhibited significant hyperlocomotor behavior, depressive symptoms and cognitive deficits. Results are further strengthened with a marked increase in lipid per oxidation (LPO) in brain and a decline in reduced glutathione (GSH) levels. Biogenic amine levels (Dopamine, DA; 5-hydroxytryptamine, 5-HT) were also significantly increased and decreased respectively. Thus, present findings suggest that dizocilpine can be used as one of the best drug to develop psychosis-like symptoms in rats and to develop an animal model following a short-term study.

RESUMEN

Ginger (Zingiber Officinale) is known over the centuries for its medicinal properties and has been used worldwide as health supplement and for treatment of several diseases. The purpose of this study was to evaluate the effects of whole ginger extract administration on spatial and recognition memory using experimental animal models. The antimicrobial properties of ginger extract against various pathogenic fungal and bacterial species were also examined. Aqueous extract of ginger at a dose of 500 mg/kg was orally administered to test rats and water was orally given to control rats for 6 weeks. Water Maze task (WM) was used to assess spatial memory and recognition memory of rats was evaluated by the Novel Object Recognition (NOR) task. Time spent with novel object was significantly increased in ginger treated rats as compared to control animals in novel object recognition task exhibiting enhanced recognition memory in ginger treated rats. Ginger treated rats exhibited significantly enhanced both short term memory and long term memory as evidenced by decrease in time to reach the hidden platform 1h and 24 h after training as compared to control rats. Short term memory functions of ginger treated rats were more enhanced than long term memory functions. Our findings suggest that ginger consumption may lead to an improvement in spatial and recognition memory. Significant activity of aqueous ginger extract was observed against pathogenic bacteria as well as fungal species. It is therefore suggested in this study that ginger extract can be used in microbial infections and as a memory enhancing drug in various memory disorders.

RESUMEN

Energy drinks enhance physical endurance and cognitive ability. The ingredients present in these drinks are considered as ergogenic and have memory boosting effects. In the present study effects of taurine administration for one week was monitored on physical exercise and memory performance in rats. Animals were divided into two groups namely control and test. Taurine was injected intraperitoneally to the test group at the dose of 100mg/kg. After one week of treatment rats were subjected to physical exercise and memory task. Results of this study revealed that rats injected with taurine for one week exhibited improved muscular strength as well as enhanced memory performance in Morris water maze and elevated plus maze. Biomarker of lipid peroxidation was significantly reduced in brain and plasma of test animals. Taurine administration also resulted in higher levels of corticosterone in this study. The results highlight the significance of taurine ingestion in energy demanding and challenging situations in athletes and young subjects.
