Solid lipid nanoparticles (SLNs), the potential novel vehicle for enhanced in vivo efficacy of hesperidin as an anti-inflammatory agent.

Hesperidin (C28H34O15), a flavanone glycoside abundantly present in citrus fruits, has proven therapeutic effects including anti-inflammatory activities. Herein, we report a novel formulation of HESP loaded solid lipid nanoparticles (SLNs) using hot homogenization and ultrasound to improve the poor solubility and bioavailability. In the present study, the formulation was developed and optimized by response surface method and then characterized by scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy (FT-IR), and dynamic light scattering (DLS). Encapsulation efficiency was determined and the anti-inflammatory effect was assessed through in vivo ear edema inflammation model. According to the electron microscopy results, the product has a spherical shape. The optimized parameters produced small size (179.8 ± 3.6 nm) HESP-SLNs with high encapsulation efficiency (93.0 ± 3.8 %). The outcomes exhibited that encapsulation in SLNs carriers improves the anti-inflammatory potential of HESP.

A review on pain-relieving activity of berberine.

As isoquinoline alkaloid naturally occurs in Coptis and Berberis species, berberine (BER) has shown anti-oxidant, anti-tumour, anti-bacterial and hepatoprotective activities and beneficial effects against digestive, cardiovascular and neurological conditions. Also, BER antiinflammatory, pain-relieving and anti-cholinesterase activities were widely studied. The present overview discusses the analgesic effects of BER. Based on the literature, BER exerted pain-relieving activity against diabetic and chemotherapy-induced neuropathy, and sciatic nerve injury-induced pain via down-regulation of transient receptor potential vanilloid 1, suppression of NF-κB and modulation of µ and δ opioid receptors. Besides, BER could repress inflammatory markers tumour necrosis factor-α, interleukin-6 and IL-1ß, as well as prostaglandin E2, inducible nitric oxide synthase and cyclooxygenase-2. The modulatory effects of BER on dopamine and N-methyl d-aspartate systems were also noted. Moreover, BER could induce Nrf2 expression but inhibits p38-MAPK and STAT3 phosphorylation. Noteworthy, anti-cholinesterase activity, which may potentially contribute to BER analgesic properties, warrants particular attention.

Cardioprotective effects of hesperidin on carbon monoxide poisoned in rats.

Carbon monoxide (CO) poisoning causes cardiotoxicity and so far, no definite antidote has been proposed to overcome CO-induced adverse outcomes. Hesperidin, a citrus flavonoid, has shown cardio-protective effects in cardiac ischemia/reperfusion models. This study investigated the protective effects of hesperidin against CO-induced cardiac injury. To induce CO poisoning, rats were exposed to CO at 3000 ppm for 60 min. On the exposure day and the four following days, hesperidin (at three different doses of 25, 50, and 100 mg/kg/day) was administered intraperitoneally. A group of animals received normal saline and served as the control group. The electrocardiogram (ECG) was recorded and evaluated with special focus on S-T segment changes (depression or elevation), T-wave alterations, AV block and ventricular and supraventricular arrhythmias. On day 6 (i.e., the day after the last injection day), the animals were sacrificed and the hearts were harvested and evaluated for necrosis using hematoxylin and eosin staining. In addition, Akt protein expression levels and BAX/BCL2 ratio were determined by western blotting. Our results showed that hesperidin decreased cardiac necrosis. In animals treated with hesperidin 100 mg/kg, Akt protein expression was increased, while the BAX/BCL2 ratio was significantly decreased. ECG changes were reversed in all groups 2 h following CO exposure, regardless of hesperidin administration. Overall, hesperidin decreased the deleterious cardiac effects of CO poisoning in rats.

Knowledge, attitude, and practice of pharmacy and medical students regarding self-medication, a study in Zabol University of Medical Sciences; Sistan and Baluchestan province in south-east of Iran.

BACKGROUND: Self-medication is defined as using medicinal products to treat the disorders or symptoms diagnosed by oneself. Although informed self-medication is one of the ways to reduce health care costs, inappropriate self-treatment can pose various risks including drug side effects, recurrence of symptoms, drug resistance, etc. The purpose of this study was to investigate the knowledge, attitude, and practice of pharmacy and medical students toward self-medication. METHODS: This study was conducted in Zabol University of Medical Sciences in 2018. Overall, 170 pharmacy and medical students were included. A three-part researcher-made questionnaire was designed to address the students' knowledge, attitude, and practice. Statistical analysis was performed in SPSS 25 software. RESULTS: According to the results, 97 (57.1%) students had carried out self-medication within the past 6 months. Overall, the students self-medicated on average 4.2 ± 2.9 times per year. Self-medication was more common in male students (65.4%, P = 0.043). Cold was the most common ailment treated with self-medication (93.2%), and antibiotics (74.4%) were the most commonly used drugs. The primary information sources used by the students were their previous prescriptions (47.4%). Pharmacy students had a higher level of drug information (P < 0.001). There was a statistically significant association between the level of drug information and the tendency for self-medication (P = 0.005). Disease recurrence was the most common negative complication of self-medication. CONCLUSION: There is a need to educate pharmacy and medical students regarding self-medication and its side effects. The high prevalence of self-medication and the overuse of antibiotics can pose a significant risk of drug resistance.

Colon cancer therapy by focusing on colon cancer stem cells and their tumor microenvironment.

Despite many advances and optimization in colon cancer treatment, tumor recurrence and metastases make the development of new therapies necessary. Colon cancer stem cells (CCSCs) are considered as the main triggering factor of cancer progression, recurrence, and metastasis. CCSCs as a result of accumulated genetic and epigenetic alterations and also complex interconnection with the tumor microenvironment (TME) can evolve and convert to full malignant cells. Mounting evidence suggests that in cancer therapy both CCSCs and non-CCSCs in TME have to be regarded to break through the limitation of current therapies. In this regard, stem cell capabilities of some non-CCSCs may arise inside the TME condition. Therefore, a deep knowledge of regulatory mechanisms, heterogeneity, specific markers, and signaling pathways of CCSCs and their interconnection with TME components is needed to improve the treatment of colorectal cancer and the patient's life quality. In this review, we address current different targeted therapeutic options that target cell surface markers and signaling pathways of CCSCs and other components of TME. Current challenges and future perspectives of colon cancer personalized therapy are also provided here. Taken together, based on the deep understanding of biology of CCSCs and using three-dimensional culture technologies, it can be possible to reach successful colon cancer eradication and improvise combination targeted therapies against CCSCs and TME.

Thrombolytic Agents: Nanocarriers in Controlled Release.

Thrombosis is a life-threatening pathological condition in which blood clots form in blood vessels, obstructing or interfering with blood flow. Thrombolytic agents (TAs) are enzymes that can catalyze the conversion of plasminogen to plasmin to dissolve blood clots. The plasmin formed by TAs breaks down fibrin clots into soluble fibrin that finally dissolves thrombi. Several TAs have been developed to treat various thromboembolic diseases, such as pulmonary embolisms, acute myocardial infarction, deep vein thrombosis, and extensive coronary emboli. However, systemic TA administration can trigger non-specific activation that can increase the incidence of bleeding. Moreover, protein-based TAs are rapidly inactivated upon injection resulting in the need for large doses. To overcome these limitations, various types of nanocarriers have been introduced that enhance the pharmacokinetic effects by protecting the TA from the biological environment and targeting the release into coagulation. The nanocarriers show increasing half-life, reducing side effects, and improving overall TA efficacy. In this work, the recent advances in various types of TAs and nanocarriers are thoroughly reviewed. Various types of nanocarriers, including lipid-based, polymer-based, and metal-based nanoparticles are described, for the targeted delivery of TAs. This work also provides insights into issues related to the future of TA development and successful clinical translation.

Effects of curcumin on ion channels and pumps: A review.

Curcumin, an orange-yellow lipophilic polyphenolic molecule, is the active component of Curcuma longa, which is extensively used as a spice in most of the Asian countries. This natural compound is able to interact with a large number of molecular structures like proteins, enzymes, lipids, DNA, RNA, transporter molecules, and ion channels. It has been reported to possess several biological effects such as antioxidant, anti-inflammatory, wound healing, antimicrobial, anticancer, antiangiogenic, antimutagenic, and antiplatelet aggregation properties. These beneficial effects of curcumin are because of its extraordinary chemical interactions such as extensive hydrogen and covalent bonding, metal chelation, and so on. Therefore, the aim of this review was to outline the evidence in which curcumin could affect different types of ion channels and ion channel-related diseases, and also to elucidate basic molecular mechanisms behind it. © 2019 IUBMB Life, 2019.

The regulatory role of curcumin on platelet functions.

Curcumin, the main ingredient of Curcuma longa L., has been used as a spice and as a herbal medicine with different therapeutic characteristics for centuries in Asian countries. This phytochemical has been shown to possess beneficial antiplatelet activity that has introduced it as a promising candidate for the treatment of thromboembolism, atherothrombosis, and inflammatory diseases. Platelet dysfunction under different circumstances may lead to cardiovascular disease, and curcumin has been shown to have beneficial effects on platelet dysfunction in several studies. Therefore, this narrative review is aimed to summarize available evidence on the antiplatelet activity of curcumin and related molecular mechanisms for this activity.

Neuro-Protective Effects of Resveratrol on Carbon Monoxide-Induced Toxicity in Male Rats.

Acute carbon monoxide (CO) poisoning causes neurotoxicity through induction of necrosis, apoptosis, lipid peroxidation and oxidative stress. Resveratrol (RES) is a natural polyphenolic phytoalexin that exhibits neuroprotective effects in ischemia/reperfusion due to its anti-apoptotic, anti-necrotic and strong anti-oxidant properties as well as its ability to activate pro-survival pathways. In this study, rats were exposed to CO 3000 ppm for 1 h. Immediately after poisoning and on the next four consecutive days, RES (1, 5 and 10 mg/kg) was administered intraperitoneally. On the fifth day, animals' brains were excised, and necrosis, lipid peroxidation level and the level of Akt, BAX and BCL2 expression were evaluated. The results showed that RES 10 mg/kg significantly reduced lipid peroxidation, but RES 1 and 5 mg/kg had no significant effect on this parameter. Furthermore, RES 5 and 10 mg/kg significantly increased Akt expression level, while BAX/BCL2 ratio was reduced by RES 1, 5 and 10 mg/kg. Moreover, RES reduced necrotic foci in the brain, but the best results were seen following treatment with RES 10 mg/kg. In summary, RES showed neuroprotective effect in CO-poisoned rats as it decreased necrosis and BAX/BCL2 ratio and increased Akt expression levels. Copyright © 2017 John Wiley & Sons, Ltd.

G-CSF administration attenuates brain injury in rats following carbon monoxide poisoning via different mechanisms.

Acute severe carbon monoxide (CO) poisoning induces hypoxia that leads to cardiovascular and nervous systems disturbances. Different complex mechanisms lead to CO neurotoxicity including lipid peroxidation, inflammatory and immune-mediated reactions, myelin degeneration and finally neuronal apoptosis and necrosis. Granulocyte colony-stimulating factor (G-CSF) is considered to be a novel neuroprotective agent. In this study, we evaluated the efficacy of G-CSF therapy on CO neurotoxicity in rats with acute CO poisoning. Rats were exposed to 3000 ppm CO in air (0.3%) for 1 h, and then different doses (50,100, and 150 µg/kg) of G-CSF or normal saline were administrated intraperitoneally. Water content of brain as an indicator for total edema and blood brain barrier integrity (Evans blue extravasation) were evaluated. Malondialydehyde was determined in order to evaluate the effect of G-CSF on CO-induced lipid peroxidation in brain tissues. Also, the effect of G-CSF on myeloperoxidase activity in the brain tissue was evaluated. The effect of G-CSF administration on induced apoptosis in the brain was measured using TUNEL method. To evaluate the level of MBP, STAT3 and pSTAT3 and HO-1 proteins and the effect of G-CSF on these proteins Western blotting was carried out. G-CSF reduced water content of the edematous poisoned brains (100 µg/kg) and BBB permeability (100 and 150 µg/kg) (P < 0.05). G-CSF (150 µg/kg) reduced the MDA level in the brain tissues (P < 0.05 as compared to CO poisoned animals). G-CSF did not decrease the MPO activity after CO poisoning in any doses. G-CSF significantly reduced the number of apoptotic neurons and Caspase 3 protein levels in the brain. Western blotting results showed that G-CSF treatment enhanced expression of HO-1 and MBP, STAT3 and pSTAT3 proteins in the brain tissues. Based on our results, a single dose of G-CSF immediately after CO poisoning significantly attenuates CO neurotoxicity via different mechanisms. © 2015 Wiley Periodicals, Inc.

Modulation of JAK2, STAT3 and Akt1 proteins by granulocyte colony stimulating factor following carbon monoxide poisoning in male rat.

Carbon monoxide (CO) is an odorless, colorless, tasteless and non-irritating by-product of inefficient combustion of hydrocarbon fuels such as motor vehicle exhausted gases. It is the leading cause of mortality in the USA among all unintentional toxicants. Male rats exposed to CO poisoning in the heart has many cardiovascular effects such as, cardiomyopathy, tachycardia, arrhythmias, and ischemia and in severe cases, myocardial infarction (MI) and cardiac arrest. Cardiomyocyte apoptosis is one of the most frequent consequences in the heart. Granulocyte colony stimulating factor (G-CSF) is a cytokine that mobilizes and differentiates granulocytes from stem cells. It can stimulate many anti-apoptotic pathways such as JAK2-STAT3 and PI3-Akt kinases following cardiac ischemia. G-CSF exerts its anti-apoptotic effects through binding to its specific cell surface receptor. The purpose of this study was to elucidate the mechanism of anti-apoptotic effect of G-CSF following CO poisoning. Rats were exposed to CO 1500 or 3000 ppm for 60 min. Animals received G-CSF 100 µg/kg subcutaneously for five consecutive days after CO intoxication. Western blot analysis was used to evaluate the expression of six proteins namely JAK2, p-JAK2, STAT3, p-STAT3, Akt1 and p-Akt1 following G-CSF 100 µg/kg consecutive dose administration after CO poisoning. There was a significant difference between phosphorylated proteins including p-JAK2, p-STAT3 and p-Akt1 in the G-CSF groups and those in control groups and there were not any significant differences in total protein among the groups.

Hesperidin neuroprotective effects against carbon monoxide-induced toxicity in male rats.

Carbon monoxide (CO) is produced via incomplete combustion of fossil fuels and it may cause long-term neurological sequel upon exposure. Hesperidin (HES), a flavanone glycoside found in citrus plants, exerts diverse beneficial health effects. The present study mechanistically examined the neuroprotective effects of HES in CO-poisoned rats. Thirty male Wistar rats (five groups of six animals) were exposed to 3000 ppm CO for 1 h. Immediately after the exposure and on the next 4 consecutive days (totally five doses), rats intraperitoneally received either normal saline (the control group) or different doses of HES (25, 50, and 100 mg/kg). A sham group that was not exposed to CO was also considered. After evaluation of spatial learning and memory using a Morris water maze (MWM), animals were sacrificed and oxidative stress status in blood samples, and Akt, Bax, Bcl2, and brain-derived neurotrophic factor (BDNF) expression in brain samples were assessed. Western blot analysis indicated increased Akt but decreased Bax/Bcl2 levels in the HES 100 mg/kg, and induced BDNF levels in all HES-treated groups. MWM results showed that HES significantly decreased memory loss. The current findings indicate that HES could alleviate neurological impairments induced by CO in rats.

Hormetic effects of curcumin on oxidative stress injury induced by trivalent arsenic in isolated rat hepatocytes.

Objective: Arsenic (As) poisoning is a worldwide public health problem. Arsenic can cause cancer, diabetes, hepatic problems, etc. Hence, we investigated possible hepatoprotective properties of curcumin against As3+-induced liver damages in freshly isolated rat hepatocytes. Materials and Methods: Isolation of hepatocytes was done by the two-step liver perfusion method using collagenase. The EC50 concentration of As3+ was used in toxicity assessments and curcumin (2, 5, and 10 µM) was added 15 min before As3+ addition to isolated hepatocytes. Curcumin impact was assessed in terms of cytotoxicity, lipid peroxidation induction, reactive oxygen species (ROS) levels, and mitochondrial membrane potential. Results: As3+ significantly increased cytotoxicity, malondialdehyde and ROS levels and induced mitochondrial membrane damage and hepatocyte membrane lysis after 3 hr incubation. Curcumin 2 µM significantly prevented lipid peroxidation induction, ROS formation, and mitochondrial membrane damage; while curcumin 5 µM had no apparent effect on these parameters, curcumin 10 µM potentiated them. Conclusion: Curcumin only at low doses could ameliorate oxidative stress injury induced by As3+ in isolated rat hepatocytes.

Effects of granulocyte colony-stimulating factor on electrocardiogram changes after carbon monoxide poisoning in rats.

Carbon monoxide (CO), which is produced by the incomplete combustion of hydrocarbons, has many toxic effects on different organs, especially the brain and heart. CO-induced cardiotoxicity leads to several deleterious effects, including electrocardiogram (ECG) abnormalities. The present study aimed to evaluate the protective effect of recombinant human granulocyte colony-stimulation factor (G-CSF) on ECG after CO poisoning in rats. Single and multiple doses of G-CSF (10, 50, and 100 µg/kg) were administered to groups, each containing 5 male Wistar rats (16 groups for ECG analysis and 16 groups for pathological analysis). Rats were already exposed to CO at either 1,500 or 3,000 ppm concentrations for 60 minutes. ECG findings (e.g., ST-segment and T-wave changes), cardiac arrhythmias (e.g., heart blocks and ventricular and supraventricular arrhythmias), and histological changes were determined after G-CSF administration. At 3,000 ppm, frequencies of ST elevation, depression, and T inversion in ECG were significantly reduced after G-CSF treatment. Also, some of the cardiac arrhythmias (e.g., atrioventricular block type 1 and 2) after CO poisoning were suppressed after G-CSF treatment. However, G-CSF did not show protective effects on cardiomyocyte pathological consequences in CO-poisoned rats. Therefore, G-CSF could protect against ECG changes after CO-induced cardiac ischemia, but did not affect pathological changes.

Effects of gallic acid on intraperitoneal adhesion bands in rats.

Objective: Gallic acid (GA) is an organic acid that possesses anti-inflammatory effects as it inhibits the production of metalloproteinases, tissue plasminogen activator, growth factors and adhesion molecules. Since formation of abdominal surgery-induced adhesion bands is accompanied by inflammation, angiogenesis and cell proliferation, in the current study, we assessed potential beneficial properties of GA against adhesion bands formation in rats. Materials and Methods: Thirty-six adult male rats were assigned into six groups of six animals. After induction of anesthesia, peritoneal injury was induced using a standard method and animals received either GA (10, 25, 50 and 100 mg/kg), or normal saline, while a group of rats remained intact. Seven days after the surgery, animals were decapitated and samples were collected for pathology evaluations. Also, lipid peroxidation (TBARS) and tumor necrosis factor alpha (TNF-α) levels were determined in serum samples. Results: Our results showed that GA significantly reduced lipid peroxidation in serum samples but had no effect on TNF-α levels. Furthermore, microscopic and macroscopic injuries reduced significantly in GA-treated animals. Conclusion: Since GA reduced adhesion bands formation at microscopic and macroscopic levels, it could be considered a treatment against adhesion bands formation.

Intrahippocampal co-administration of nicotine and O-acetyl-L-carnitine prevents the H-89-induced spatial learning deficits in Morris water maze.

OBJECTIVES: H-89 (a protein kinase AII [PKA II] inhibitor) impairs the spatial memory in the Morris water maze task in rats. In the present study, we aimed to study the protective effects of nicotine and O-acetyl-L-carnitine against H-89-induced spatial memory deficits. METHODS: Spatial memory impairment was induced by the bilateral intrahippocampal administration of 10 µM H-89 (dissolved in dimethyl sulfoxide, DMSO) to rats. The rats then received bilateral administrations of either nicotine (1 µg/µL, dissolved in saline) or O-acetyl-L-carnitine (100 µM/side, dissolved in deionized water) alone and in combination. Control groups received either saline, deionized water, or DMSO. RESULTS: The H-89-treated animals showed significant increases in the time and distance travelled to find hidden platforms, and there was also a significant decrease in the time spent in the target quadrant compared to DMSO-treated animals. Nicotine and O-acetyl-L-carnitine had no significant effects on H-89-induced spatial learning impairments alone, but the bilateral intrahippocampal co-administration of nicotine and O-acetyl-L-carnitine prevented H-89-induced spatial learning deficits and increased the time spent in the target quadrant in comparison with H-89-treated animals. CONCLUSIONS: Our results indicated the potential synergistic effects of nicotine and O-acetyl-L-carnitine in preventing protein kinase AII inhibitor (H-89)-induced spatial learning impairments.

Effects of Quercetin and Resveratrol on Zinc Chloride- and Sodium Metavanadate-Induced Passive Avoidance Memory Retention Deficits in Male Mice.

Quercetin and resveratrol are found in a variety of fruits and vegetables and have several biological and pharmacological properties. In this study, the effects of quercetin [50 mg/kg, intraperitoneal (i.p.)] and resveratrol (50 mg/kg, i.p.) on zinc chloride (ZnCl2; 75 mg/kg/d, 2 weeks oral gavage) and sodium metavanadate (SMV; 22.5 mg/kg/d, 2 weeks oral gavage) induced passive avoidance memory retention were investigated in step-through passive avoidance tasks. ZnCl2 was dissolved in saline and SMV was dissolved in drinking water. Mice received ZnCl2 or SMV orally for two weeks and were administered quercetin or resveratrol by i.p. injection on day 14, days 12 and 14, or days 10, 12, and 14. At the end of treatment, animals were trained for one day in a step-through passive avoidance task, then alterations in avoidance memory retention were evaluated after 24, 48, 96, and 168 h. Oral consumption of ZnCl2 and SMV decreased latency time compared with control groups. Both quercetin and resveratrol (50 mg/kg, i.p.) prevented ZnCl2- and SMV-induced avoidance memory retention impairments and did not significantly alter muscle strength, as demonstrated in rotarod tasks. No significant differences were observed between mice who received single, double, or triple doses of quercetin or resveratrol. The results suggest that quercetin and resveratrol may have preventive effects on ZnCl2- and SMV-induced memory impairment in male mice.

Nanoscale Metal-Organic Frameworks: Recent developments in synthesis, modifications and bioimaging applications.

Porous Metal-Organic Frameworks (MOFs) have emerged as eye-catching materials in recent years. They are widely used in numerous fields of chemistry thanks to their desirable properties. MOFs have a key role in the development of bioimaging platforms that are hopefully expected to effectually pave the way for accurate and selective detection and diagnosis of abnormalities. Recently, many types of MOFs have been employed for detection of RNA, DNA, enzyme activity and small-biomolecules, as well as for magnetic resonance imaging (MRI) and computed tomography (CT), which are valuable methods for clinical analysis. The optimal performance of the MOF in the bio-imaging field depends on the core structure, synthesis method and modifications processes. In this review, we have attempted to present crucial parameters for designing and achieving an efficient MOF as bioimaging platforms, and provide a roadmap for researchers in this field. Moreover, the influence of modifications/fractionalizations on MOFs performance has been thoroughly discussed and challenging problems have been extensively addressed. Consideration is mainly focused on the principal concepts and applications that have been achieved to modify and synthesize advanced MOFs for future applications.

Carbon based nanomaterials for the detection of narrow therapeutic index pharmaceuticals.

Precise detection of important pharmaceuticals with narrow therapeutic index (NTI) is very critical as there is a small window between their effective dose and the doses at which the adverse reactions are very likely to appear. Regarding the fact that various pharmacokinetics will be plausible while considering pharmacogenetic factors and also differences between generic and brand name drugs, accurate detection of NTI will be more important. Current routine analytical techniques suffer from many drawbacks while using novel biosensors can bring up many advantages including fast detection, accuracy, low cost with simple and repeatable measurements. Recently the well-known carbon Nano-allotropes including carbon nanotubes and graphenes have been widely used for development of different Nano-biosensors for a diverse list of analytes because of their great physiochemical features such as high tensile strength, ultra-light weight, unique electronic construction, high thermo-chemical stability, and an appropriate capacity for electron transfer. Because of these exceptional properties, scientists have developed an immense interest in these nanomaterials. In this case, there are important reports to show the effective Nano-carbon based biosensors in the detection of NTI drugs and the present review will critically summarize the available data in this field.
