Objectives: This study aimed to explore the impact of aerobic interval training (AIT) combined with Ginkgo biloba (GB) supplementation on passive avoidance memory function and the expression of the glial cell-derived neurotrophic factor (GDNF) gene in rats afflicted with AD. Methods: A total of forty-four male Wistar rats, each weighing approximately 250 ± 20 g, were maintained in a controlled environment at a specified temperature. Over 8 weeks (5 days per week), they underwent AIT and received GB supplements at a dosage of 100 mg/kg. The rats were randomly assigned into six groups: healthy control (HC) with 7 rats, AD control (AC) with 8 rats, amyloid-β (Aβ) injection plus GB supplement (Aβ + GB) with 8 rats, Aβ injection plus GB supplement plus AIT (Aβ + GB + AIT) with 8 rats, Aβ injection plus AIT (Aβ + AIT) with 8 rats, and sham surgery (SS) with 5 rats. The shuttlebox apparatus was utilized to assess the effect of Aβ on passive avoidance memory and to confirm disease induction. GDNF gene expression was measured using the qRT-PCR method. Results: The study found significant improvements in passive avoidance memory in the Aβ + AIT and Aβ + GB + AIT groups compared to the AC group after 8 weeks of AIT and GB supplementation (P = 0.02 and P = 0.000, respectively). Long-term memory performance was notably enhanced in the Aβ + GB + AIT group (P = 0.000). Additionally, GDNF expression significantly increased in the Aβ + GB + AIT and Aβ + GB groups in comparison to the AC group (P = 0.000 and P = 0.01, respectively). Conclusions: A synergistic effect of AIT and GB supplementation was observed, leading to an increase in GDNF gene expression and improvements in both passive avoidance memory and long-term memory in male rats with AD.","PeriodicalId":17745,"journal":{"name":"Jundishapur Journal of Natural Pharmaceutical Products","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140246708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One crucial signaling pathway involved in wound healing is the Wnt signaling pathway. This study aimed to investigate the effects of a cocktail consisting of L-carnosine, zinc sulfate, and B-complex vitamins on the modulation of the Wnt signaling pathway during wound healing. Methods: The optimal dosages of L-carnosine, zinc sulfate, and B-complex were used to prepare the cocktail. Then, the cocktail-mediated wound healing was measured through scratch assay on human dermal fibroblast (HDF) cells. Finally, the effects of the cocktail on the expression of SFRP1, SFRP2, SFRP4, MMP7, and RSPO2 genes involved in the Wnt signaling pathway were measured during the wound closure phenomenon by real-time quantitative polymerase chain reaction (RT-qPCR). Results: The scratch assay demonstrated the wound-healing effects of the prepared cocktail on HDF cells. Additionally, the RT-qPCR results showed that the cocktail can activate the Wnt signaling pathway by down-regulating the expression of SFRP1, SFRP2, SFRP4, and MMP7 and up-regulating the expression of RSPO2. Conclusions: The data suggest that the L-carnosine, zinc sulfate, and B-complex vitamin cocktail exhibits wound healing properties by increasing fibroblast proliferation via the activation of the Wnt pathway.","PeriodicalId":17745,"journal":{"name":"Jundishapur Journal of Natural Pharmaceutical Products","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140247348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been shown to have cardiovascular, metabolic, neuroendocrine, and urinary effects on the body. There is abundant scientific evidence that establishes a strong correlation between arsenic exposure and kidney-related disorders. Objectives: The present study aimed to investigate the potential protective effect of citicoline against NaAsO2-induced nephrotoxicity. Methods: The groups included a control group, a group treated with NaAsO2 at a concentration of 50 ppm, a group treated with Cit at a dosage of 1000 mg/kg, and three groups of NaAsO2 (50 ppm) co-treated with Cit at doses of 250, 500, and 1000 mg/kg, respectively. Results: Citicoline decreased the activity level of blood urea nitrogen (P < 0.001), creatinine levels (P < 0.001), thiobarbituric acid reactive substances (P < 0.001), nitric oxide (P < 0.001), inflammatory factors such as tumor necrosis factor-α (P < 0.001) and interleukin-6 (P < 0.001 and P < 0.001). Furthermore, Cit increased total thiol (P < 0.001) and activity levels of catalase (P < 0.05 and P < 0.001), superoxide dismutase (P < 0.01 and P < 0.001), and glutathione peroxidase (P < 0.001). Therefore, Cit reduced the harmful effects caused by the imbalance in oxidative and antioxidant systems and histopathological damage in NaAsO2-intoxicated mice, improving the damage caused by oxidative stress and inflammation. Conclusions: Our research indicates that Cit can shield the kidneys from the damaging effects of NaAsO2 by leveraging its antioxidant and anti-inflammatory properties.","PeriodicalId":17745,"journal":{"name":"Jundishapur Journal of Natural Pharmaceutical Products","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140417570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The well diffusion method revealed the inhibitory effect of the extract, with the highest activity observed against Streptococcus salivarius. Subsequently, MIC and MBC values were determined, indicating that the hydroalcoholic extract had MIC and MBC values of 3.12 mg/mL against Streptococcus sanguinis and 6.25 mg/mL against other strains (Streptococcus mitis, Streptococcus mutans, Streptococcus sanguinis, and Streptococcus salivarius). Chlorhexidine exhibited significantly lower MIC and MBC values of 0.0003%. Based on literature reviews, Allium species exhibit antimicrobial properties. The findings highlight the potential of Allium atroviolaceum extract as an alternative or complementary antimicrobial agent and warrant further investigation to identify its bioactive components and explore their mechanisms of action.

Its many beneficial compounds make it a valuable natural remedy for numerous health conditions. Objectives: The present study investigated the preventive effect of castor oil on malathion-induced Parkinson's disease (PD)-like behaviors in rats. Methods: Rats were divided into 8 groups: control (normal saline), malathion (100 mg/kg/day, intraperitoneal injection (IP)), castor oil (0.05, 0.1, or 0.5 mL/kg/day, orally) plus malathion, levodopa (10 mg/kg/day, IP) plus malathion, castor oil (0.5 mg/kg/day, orally), and polyethylene glycol (PEG) (vehicle of levodopa) groups. All treatments were administered for 28 days, after which neurobehavioral tests such as open field, rotarod, and catalepsy were performed. The activity of acetylcholinesterase (AChE) in serum and the levels of malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor α (TNFα), and interleukin (IL)-6 in the striatum were measured at the end of the treatment period to assess the potential effects of castor oil. Results: The finding of this study indicated that malathion-induced neurobehavioral toxicity was together with the increase of MDA, TNFα, and IL-6 levels, a decrease of GSH, and AChE activity that was reversed by treatment with castor oil. Conclusions: Overall, these results suggest that castor oil may have potential therapeutic effects for PD by improving antioxidant status and reducing oxidative stress and inflammation, which are both factors that can contribute to the toxicity of pesticides like malathion.

Probiotics have shown promise as a potential alternative treatment for constipation. Objectives: The main goal of this study is to assess the effects of an Iranian multispecies synbiotic supplement on FC. Methods: This randomized controlled trial (RCT) recruited 115 adult patients who met the Rome IV criteria for FC after fulfilling the inclusion criteria. They were randomly assigned to receive either psyllium (n = 57) or psyllium plus synbiotic (n = 58) daily for 4 weeks. The treatment response was evaluated based on changes in stool consistency (based on the Bristol scale), bloating severity, and constipation intensity (based on the Wexner Constipation Scoring System), and those with a partial to excellent response were considered treatment successes. Results: The two groups did not differ in terms of sex, age, and BMI. The downward trend of stool consistency, bloating, as well as, constipation intensity was significant after 2 weeks of synbiotic-containing intervention. Treatment success after 4 weeks was 75.44% in the synbiotic group, compared to 30.91% in the psyllium-alone group (P < 0.001), indicating the superior efficiency of the synbiotic. Neither treatment exhibited adverse effects (P = 0.924), although psyllium was found to be less tolerable than the synbiotic (P = 0.026).

Objectives: This study investigated the chemical composition, antioxidant activity, and α-glucosidase inhibitory activity of Salvia mirzayanii Rech. f. and Esfand. and Salvia hypoleuca Benth. essential oils (EOs). Additionally, the enzyme inhibitory activity of the mixture of compounds was evaluated to find whether the synergistic effect is responsible for the desired activity or not. Methods: The constituents of S. mirzayanii and S. hypoleuca EOs collected from Fars and Alborz provinces, Iran, were determined using gas chromatography-mass spectroscopy (GC-MS) analysis. They were evaluated for their α-glucosidase inhibitory activity by the determination of para-nitrophenol (pNP), derived from the enzymatic degradation of para-nitrophenol-D-glucopyranoside (pNPG) as the substrate. The activity of the selected components was also tested. Moreover, the antioxidant activity of EOs was evaluated based on the radical scavenging capability (2,2-Diphenyl-1-picrylhydrazyl [DPPH]) assay, and their total phenolic content (TPC) was determined using the Folin-Ciocalteu method in terms of gallic acid equivalent (GAE). Results: In total, 66 compounds were detected in the S. mirzayanii and S. hypoleuca EOs. The results showed that S. mirzayanii EO had more potent antioxidant activity (half-maximal inhibitory concentration [IC50] = 0.77 ± 0.00 mg/mL), higher TPC (78.26 ± 1.26 mg GAE/g EO), and a greater inhibitory effect toward α-glucosidase (IC50 = 55.15 ± 1.60 mg/mL) than S. hypoleuca EO. Furthermore, caryophyllene oxide (IC50 = 19.94 ± 0.26 mg/mL), α-pinene (IC50 = 17.59 ± 0.19 mg/mL), and linalool (IC50 = 38.00 ± 0.22 mg/mL) showed high levels of α-glucosidase inhibitory activity among the major constituents. In addition, the combination of linalool: 1,8-cineole: α-terpineol (40: 35: 25) inhibited this enzyme synergistically (combination index [CI] < 1).
