Various studies have been conducted on the effect of medicinal plants in the treatment of different diseases, including diabetes. Nigella Sativa (N. sativa) is a plant with edible and medicinal properties that are of interest to scientists in traditional and complementary medicine, and much research has been conducted on this plant. Comprehensive reports are used to investigate the effect of N. sativa in vitro, animal models, and clinical trials in the treatment of diabetic diseases. An online database search was conducted to investigate the potential anti-diabetic effect of N. sativa. The results of various studies indicate that this plant can act as hypoglycemic, and due to antioxidant properties, it can have positive results in reducing blood sugar and glycosylated hemoglobin levels and controlling insulin secretion and glucose homeostasis. The effect of N. sativa in animal models has shown that N. sativa oil can eliminate oxygen-free radical species similar to hydroxyl free radicals and superoxide radical anions. Therefore, in this review study, we intend to address all the therapeutic aspects and effects of the black seed plant in the cellular and animal environment and clinical trial studies for the optimal use of this medicinal plant. In conclusion, the antidiabetic activities of N. sativa are indeed well established. However, in some cases, the molecular modulation underlying these activities remains unknown. N. sativa has been demonstrated to improve blood glucose and insulin levels, mitigate diabetes complications, and stimulate glucose absorption. Its antioxidant function, flavonoid and triterpenoid components, and potency to modulate insulin secretion in pancreatic cells introduced it as a safe medicinal herb for dietary adjuvant with antidiabetic medications. However, it has been declared to a decline in blood lipid profiles, and risk factors for cardiovascular diseases in Type 2 Diabetes patients. Further research must concentrate on patients unresponsive to available anti-diabetic drugs and hyperlipidemia T2D. Thus, further studies into its medicinal effects are recommended.

Zeaxanthin, an oxygenated form of carotenoid, is a well-known natural pigment and an anti-oxidant agent. Its anti-oxidant function has been shown in many studies, and it has shown no significant signs of toxicity, making it safe for therapeutic use against biologicals, chemicals, and radiation-induced toxicities. The objective of this study was to provide a comprehensive analysis and evaluation of the protective and antidotal effectiveness of zeaxanthin in mitigating the toxic effects generated by biological agents, chemical substances, natural toxins, and radiation exposure. Many studies suggest the protective effects of zeaxanthin against chemical, natural, and radiation-induced toxicities. Zeaxanthin can decrease apoptosis and inflammation, oxidative stress, pathological changes, and other effects of toxins. Besides an anti-oxidant agent, zeaxanthin can be used against many other toxicities and toxins. However, prior to utilizing zeaxanthin as a therapeutic agent for various disorders, it is imperative to conduct more clinical trials and human investigations.

Hesperidin ,Hesperetin ,Cardiovascular ,Inflammation ,Heart ,Nutrition. Foods and food supply ,TX341-641 - Abstract
This investigation aims to determine how hesperidin and hesperetin, natural flavonoids found abundantly in citrus fruits, affect cardiovascular diseases. From inception until January 2024, relevant literature was reviewed using a systematic review methodology and databases such as Scopus, PubMed, and Web of Science. Hesperidin and hesperetin counteract atherosclerosis, a key contributor to heart disease, by ameliorating lipid profiles, inhibiting plaque formation, and reducing inflammation. These flavonoids protect against drug-induced cardiotoxicity, safeguarding the heart from injury developed by arsenic trioxide, cisplatin, and doxorubicin. They enhance endothelial function, regulate blood pressure, and counteract oxidative stress. Furthermore, clinical trials also support the potential benefits of hesperidin supplementation in improving blood pressure, endothelial function, and inflammatory markers. This thorough review presents significant evidence advocating the inclusion of hesperidin and hesperetin as supplementary, innovative, and cost-efficient remedies for cardiovascular diseases.

Abstract The objective of the present investigation was to compare the coronary angiography results in diabetic patients with and without end‐stage kidney disease (ESKD). We included prolonged diabetic patients with ESKD (93 patients) and without ESKD (control group, 126 patients). Angiography of the coronary arteries was performed on all patients. Our results revealed that the ESKD patients tended to have a higher degree of coronary artery stenosis in all parts of LAD (p = 0.001, 0.024, and 0.005), proximal and distal RCA (p = 0.013, and 0.008), and proximal and distal LCX artery (p = 0.001, 0.008) than non‐ESKD patients. Furthermore, we found that the ESKD group had higher significant coronary artery stenosis in the LAD artery (60.5% vs. 39.5%, p

We aimed to evaluate the effects of seven weeks of aerobic exercise training and piperine on paraquat-induced lung damage. Forty-eight male Wistar rats (230 g, six-eight weeks old) were randomly divided into six groups (n = 8): sham, paraquat (5 mg/kg three times a week; intraperitoneally), paraquat + piperine (10 mg/kg/day; orally), paraquat + aerobic exercise training, paraquat + piperine + aerobic exercise training; and paraquat + vitamin E (20 mg/kg/day; orally) as a positive control. Rats were sacrificed on day 50, and both lung tissues were isolated to measure oxidative (MDA), anti-oxidative (GSH), inflammatory (TNF-α), anti-inflammatory (IL-10) markers, and histological evaluations (hematoxylin-eosin staining). The results of the present study revealed that paraquat significantly decreased body weight, GSH, GSH/MDA ratio, IL-10, and IL-10/TNF-α ratio while increasing MDA, TNF-α, and histopathological damage in lung tissue (P

Post-operative peritoneal adhesions (PA) are a common and important clinical problem. In this study, we focused on the ameliorative efficacy of ginger and gingerol compounds on surgical-induced peritoneal adhesion, and their strategies that disrupted the PA formation pathways to suppress their incidence. First, liquid chromatography-mass spectrometry (LC-MS) was established to separate and identify several chemical groups of ginger rhizome extract. In the next steps, male Wistar albino rats were randomly selected and divided into various groups, namely sham, control, ginger extract (0.6, 1.8, 5 %w/v), and gingerol (0.05, 0.1, 0.3, and 1 %w/v). Finally, we investigated the macroscopic parameters such as wound healing, body weight as well as spleen height and weight. In addition, visual peritoneal adhesion assessment was performed via Nair et al and Adhesion Scoring Scheme. Moreover, the microscopic parameters and biological assessment was performed via and immunoassays. The present findings revealed significant improvement in wound healing and reduction of the adhesion range, as Nair et al. and Adhesion Scoring Scheme scoring, in both the ginger and gingerol groups compared to the PA group (P

Niosomes are drug delivery systems with widespread applications in pharmaceutical research and the cosmetic industry. Niosomes are vesicles of one or more bilayers made of non-ionic surfactants, cholesterol, and charge inducers. Because of their bilayer characteristics, similar to liposomes, niosomes can be loaded with lipophilic and hydrophilic cargos. Therefore, they are more stable and cheaper in preparation than liposomes. They can be classified into four categories according to their sizes and structures, namely small unilamellar vesicles (SUVs), large unilamellar vesicles (LUVs,), multilamellar vesicles (MLVs), and multivesicular vesicles (MVVs). There are many methods for niosome preparation, such as thin-film hydration, solvent injection, and heating method. The current study focuses on the preparation methods and pharmacological effects of niosomes loaded with natural and chemical anti-inflammatory compounds in kinds of literature during the past decade. We found that most research was carried out to load anti-inflammatory agents like non-steroidal anti-inflammatory drugs (NSAIDs) into niosome vesicles. The studies revealed that niosomes could improve anti-inflammatory agents' physicochemical properties, including solubility, cellular uptake, stability, encapsulation, drug release and liberation, efficiency, and oral bioavailability or topical absorption.

Hesperidin and hesperetin, two flavonoids with potential therapeutic value, have been extensively studied in the context of diabetes management. The main objective of this research is to ascertain their potential as therapeutic options for managing diabetes and its complications. The present study utilized a systematic review methodology and comprehensively explored relevant literature from databases, including PubMed, Scopus, and Web of Science, from inception until July 2023. The review summarized the outcomes related to the molecular, cellular, and metabolic effects of hesperidin and hesperetin in diabetes and its complications. Hesperetin exhibits a potential treatment for preventing diabetes and its associated complications through modulation of inflammatory cytokine release and expression via the pathway of signaling through Toll-like receptor/Myeloid differentiation factor 88/Nuclear factor-kappa B. Hesperidin shows promise as a biomolecule for treating diabetic neuropathy, primarily through activation of nuclear factor erythroid 2-related factor 2 (Nrf-2), as an antioxidant-response element signaling, leading to neuroprotective effects. Both compounds demonstrated the ability to normalize blood glucose levels and reduce serum and liver lipid levels, making them potential candidates for managing hypoglycemia and hypolipidemia in diabetes. Hesperidin also showed potential benefits against diabetic nephropathy by suppressing transforming growth factor-β1-integrin-linked kinase-Akt signaling and enhancing renal function. Furthermore, hesperidin's antioxidant, anti-inflammatory, and anti-depressant effects in diabetic conditions expanded its potential therapeutic applications. This systematic review provides substantial evidence supporting the consideration of hesperidin and hesperetin for diabetes and its complications. It offers exciting possibilities for developing novel, cost-effective treatment options to enhance diabetes management and patient outcomes.

The crucial roles of innate and acquired immunity in the pathogenesis of allergic diseases have been well highlighted based on molecular mechanisms. Thus, the modulation of unregulated and unabated inflammatory responses is a therapeutic strategy in allergic diseases. One of the most important natural compounds with a high immune modulation and anti-inflammation potency is quercetin, found in various fruits and vegetables, namely onions, shallots, apples, and berry crops. Therefore, in this study, we reviewed the influences of quercetin against allergic conditions, including asthma, allergic rhinitis, atopic dermatitis, conjunctivitis, and anaphylaxis. Scientific databases, including PubMed, Scopus, the Web of Sciences, and EMBASE, were searched in English until March 2024. Quercetin’s beneficial effects have been attributed to its anti-cancer, anti-viral, anti-oxidant, and anti-inflammatory activities, and also a decrease in pro-inflammatory cytokines, leukotrienes production, inhibition of histamine release, and suppression of interleukin IL-4 production. It can reduce the production of antigen-specific IgE antibodies and improve the Th1/Th2 balance. These qualities of quercetin can be used as a strategy to treat asthma, allergic rhinitis, atopic dermatitis, conjunctivitis, and anaphylaxis. According to the findings of these investigations, quercetin may have a beneficial influence on allergy illnesses.

Abstract Opium abuse and exposure to heavy metals elevate the risk of coronary artery disease (CAD). Therefore, we aimed to determine the association between opium abuse and blood lead levels (BLLs) and the CAD complexity. We evaluated patients with acute coronary symptoms who underwent coronary angiography, and those with >50% stenosis in at least one of the coronary arteries were included. Furthermore, Synergy between PCI with Taxus and Cardiac Surgery I (SYNTAX I) score and BLLs were measured. Based on the opium abuse, 95 patients were subdivided into opium (45) and control (50) groups. Differences in demographics and CAD risk factors were insignificant between the two groups. The median BLLs were remarkably higher in the opium group than in controls (36 (35.7) and 20.5 μg/dL (11.45), respectively, p = 0.003). We also revealed no significant differences in SYNTAX score between the two groups (15.0 (9.0) and 17.5 (14.0), respectively, p = 0.28). Additionally, we found no significant correlation between BLLs and the SYNTAX scores (p = 0.277 and r = −0.113). Opium abuse was associated with high BLLs. Neither opium abuse nor high BLLs were correlated with the complexity of CAD. Further studies are warranted to establish better the relationship between opium abuse, BLLs, and CAD.

Autism spectrum disorder (ASD) is a group of heterogeneous neurodevelopmental disabilities with persistent impairments in cognition, communication, and social behavior. Although environmental factors play a role in ASD etiopathogenesis, a growing body of evidence indicates that ASD is highly inherited. In the last two decades, the dramatic rise in the prevalence of ASD has interested researchers to explore the etiologic role of epigenetic marking and incredibly abnormal DNA methylation. This review aimed to explain the current understanding of the association between changes in DNA methylation signatures and ASD in patients or animal models. We reviewed studies reporting alterations in DNA methylation at specific genes as well as epigenome-wide association studies (EWASs). Finally, we hypothesized that specific changes in DNA methylation patterns could be considered a potential biomarker for ASD diagnosis and prognosis and even a target for pharmacological intervention.

Objective: Psoriasis is a chronic inflammatory autoimmune disease. The effectiveness of noscapine has been employed as a helpful treatment for various disorders and subjected to recent theoretical breakthroughs.Materials and Methods: Psoriasis-like lesions were induced by topical application of 5% imiquimod (IMQ) (10 mg/cm2 of skin) in male Balb/c mice and then medicated with a single oral dose of methotrexate (MET) as a positive control or daily oral treatment of noscapine (5, 15 and 45 mg/kg). In this way, skin inflammation intensity, psoriatic itchiness, psoriasis area severity index (PASI) score, ear length, thickness, and organ weight were daily measured. At the end of the study, histological and immunohistochemical and enzyme-linked immunosorbent assays (ELISA, for pro-/anti-inflammatory factors) were performed in each ear.Results: IMQ caused psoriasis-like lesions. Noscapine markedly alleviated macroscopic parameters, namely ear thickness, ear length, skin inflammation, itching, and organ weight, as well as microscopic parameters including, pathology and Ki67 and p53, and tissue immunological mediators, such as tumour necrosis factor (TNF-α), interleukin (IL)-10, transforming growth factor (TGF-β), interferon-g (IFN-g), IL-6, IL-17, and IL-23p19 in the psoriatic skin in a concentration manner (p

Psoriasis is a chronic inflammatory skin disease characterized by thickening the epidermis with erythema, scaling, and proliferation. Noscapine (NOS) has several anti-inflammatory, anti-angiogenic, and anti-fibrotic effects, but its low solubility and large size results in its lower efficacy in the clinic. In this regard, solid lipid nanoparticles (SLN) encapsulated NOS (SLN-NOS) were fabricated using the well-known response surface method based on the central composite design and modified high-shear homogenization and ultrasound method. As a result, Precirol® was selected as the best lipid base for the SLN formulation based on Hildebrand-Hansen solubility parameters, in which SLN-NOS 1 % had the best zeta potential (−35.74 ± 2.59 mV), average particle size (245.66 ± 17 nm), polydispersity index (PDI, 0.226 ± 0.09), high entrapment efficiency (89.77 %), and ICH-based stability results. After 72 h, the SLN-NOS 1 % released 83.23 % and 58.49 % of the NOS at pH 5.8 and 7.4, respectively. Moreover, Franz diffusion cell’s results indicated that the skin levels of NOS for SLN and cream formulations were 46.88 % and 13.5 % of the total amount, respectively. Our pharmacological assessments revealed that treatment with SLN-NOS 1 % significantly attenuated clinical parameters, namely ear thickness, length, and psoriasis area and severity index, compared to the IMQ group. Interestingly, SLN-NOS 1 % reduced the levels of interleukin (IL)-17, tumor necrosis factor-α, and transforming growth factor-β, while elevating IL-10, compared to the IMQ group. Histology studies also showed that topical application of SLN-NOS 1 % significantly decreased parakeratosis, hyperkeratosis, acanthosis, and inflammation compared to the IMQ group. Taken together, SLN-NOS 1 % showed a high potential to attenuate skin inflammation.

Caffeic acid (CA) and its derivatives, caffeic acid phenyl ethyl amide (CAPA) and caffeic acid phenyl ester (CAPE), were shown to have anti-oxidant, anti-inflammatory, and anti-diabetic effects. Therefore, in this systematic review, a literature search was conducted from inception until June 2023 on major electronic databases (ISI Web of Science, MEDLINE/PubMed, Scopus, Cochrane Library, and Google Scholar) to find studies evaluating the impacts of CA and its common derivatives on diabetes and its complications in different cellular, animal, and clinical studies. CA and its derivatives therapy mitigated levels of blood glucose, oxidative stress markers, and inflammatory cytokines while increasing levels of anti-oxidative markers in different cellular and animal models of diabetes. Furthermore, they remarkably propagated insulin secretion and ameliorated insulin resistance. CA and its derivatives also revealed protective effects against diabetes complications, such as diabetic-induced hepatic damage, cardiomyopathy, endothelial dysfunction, retinopathy, cognitive deficit, nephropathy, and neuropathy.

Abstract Background and Aims Coronary artery calcification reduces elasticity and can cause hemodynamic disturbances, increasing the risk of cardiovascular complications. Furthermore, coronary calcifications make cardiovascular interventions difficult. The present study aimed to study the cardiovascular outcomes of the coronary intervention of calcified lesions in the Iranian population. Methods The present cross‐sectional study evaluated patients with moderate to severe calcified coronary artery lesions on angiography who were candidates for percutaneous coronary intervention (PCI). Demographic, echocardiographic, and angiographic data of the patients were recorded. In addition, clinical outcomes, including mortality, myocardial infarction, stroke, and stent thrombosis, were also measured 1 year after the procedure. Results A total of 125 participants (65% male and 35% female) with a median age of 69 (13.0) years old were enrolled. The most common calcification degree was 270° (43.5%), followed by 360° (35.5%) and 180° (21.0%). Most patients had thrombolysis in myocardial infarction (TIMI) score of 3 (47.6%). A more than 10% residual coronary minimum lumen diameter was seen in 25.8% of patients. Puncture site hemorrhage and contrast‐induced nephropathy were observed in 2 (1.6%) and 1 (0.8%) patients, respectively. Following 1 year after PCI, no cases of mortality, cerebrovascular accident, myocardial infarction, and stent thrombosis were reported. Furthermore, we observed one case of heart failure (0.8%) and target lesion revascularization (0.8%). In addition, we revealed a significant relationship between calcification degree and TIMI (p

In addition to the anti-diabetic effect of metformin, a growing number of studies have shown that metformin has some exciting properties, such as anti-oxidative capabilities, anticancer, genomic stability, anti-inflammation, and anti-fibrosis, which have potent, that can treat other disorders other than diabetes mellitus. We aimed to describe and review the protective and antidotal efficacy of metformin against biologicals, chemicals, natural, medications, pesticides, and radiation-induced toxicities. A comprehensive search has been performed from Scopus, Web of Science, PubMed, and Google Scholar databases from inception to March 8, 2023. All in vitro, in vivo, and clinical studies were considered. Many studies suggest that metformin affects diseases other than diabetes. It is a radioprotective and chemoprotective drug that also affects viral and bacterial diseases. It can be used against inflammation-related and apoptosis-related abnormalities and against toxins to lower their effects. Besides lowering blood sugar, metformin can attenuate the effects of toxins on body weight, inflammation, apoptosis, necrosis, caspase-3 activation, cell viability and survival rate, reactive oxygen species (ROS), NF-κB, TNF-α, many interleukins, lipid profile, and many enzymes activity such as catalase and superoxide dismutase. It also can reduce the histopathological damages induced by many toxins on the kidneys, liver, and colon. However, clinical trials and human studies are needed before using metformin as a therapeutic agent against other diseases.

Abstract The World Health Organization stated that 1.6 million deaths worldwide were caused by contact with chemicals and toxins in 2019. In the same year, the Centers for Disease Control and Prevention stated that natural toxins caused 3960 deaths. Myrtus communis, also known as common Myrtle, is a flowering plant native to the Mediterranean region. Myrtle has been traditionally used to treat diarrhea, inflammation, bleeding, headache, pulmonary and skin diseases. This review was performed to assess Myrtle's protective and therapeutic efficacy against various chemical, natural, and radiational noxious. Multiple databases such as PubMed, Web of Sciences, and Scopus were investigated without publication time limitation. Recent studies have demonstrated its potential as a protective agent against both natural and chemical toxins. One of Myrtle's most significant protective properties is its high antioxidant content. Studies have shown that the antioxidant properties of Myrtle can protect against harmful substances such as heavy metals, pesticides, and other environmental toxins. Additionally, Myrtle has anti‐inflammatory properties that can help reduce the damage caused by long‐term exposure to toxins. The anti‐inflammatory and antimicrobial properties of Myrtle have also proven effective in alleviating gastrointestinal conditions such as gastric ulcers.

Berberine (BBR) is an isoquinoline alkaloid that can be extracted from herbs such as Coptis, Phellodendron, and Berberis. BBR has been widely used as a folk medicine to treat various disorders. It is a multi-target drug with multiple mechanisms. Studies have shown that it has antioxidant and anti-inflammatory properties and can also adjust intestinal microbial flora. This review focused on the promising antidiabetic effects of BBR in several cellular, animal, and clinical studies. Based on previous research, BBR significantly reduced levels of fasting blood glucose, hemoglobin A1C, inflammatory cytokines, and oxidative stress markers. Furthermore, BBR stimulated insulin secretion and improved insulin resistance through different pathways, including up-regulation of protein expression of proliferator-activated receptor (PPAR)-γ, glucose transporter (GLUT) 4, PI3K/AKT, and AMP-activated protein kinase (AMPK) activation. Interestingly, it was demonstrated that BBR has protective effects against diabetes complications, such as diabetic-induced hepatic damage, cardiovascular disorders, nephropathy, and neuropathy. Furthermore, multiple clinical trial studies have emphasized the ameliorative effects of BBR in type 2 diabetic patients.

Condensed Matter::Materials Science - Abstract
Unusual behavior of pyroelectric current signal polarity near the Curie point ( T-c) was observed for TIGaSe2 a ferroelectric-semiconductor. It has been revealed that the polarity of the spontaneous polarization near T-c depends on the sample poling prehistory. In particular, applying an external electric field only in the temperature range of the paraelectric state during cooling regime in darkness brought to the depolarization current at I with the sign opposite to the external field polarity. Otherwise, if the sample was poled in the temperature interval of the incommensurate phase, pyroelectric current exhibits a peak at T-c with the polarity that is the same as for the external poling electric field. These observations indicate that internal electric field is present in the bulk and near-surface layer regions of the electrically poled single crystal TIGaSe2. Possible mechanisms and origins responsible for the internal electric fields in TIGaSe2 are discussed. It is shown that the formation of internal electric fields in TIGaSe2 is due to charging of intrinsic native defects during the poling process.

Abstract We aimed to determine the effects of isoproterenol on arrhythmia recurrence in atrioventricular nodal re‐entrant tachycardia (AVNRT) patients treated with catheter ablation. The present randomized controlled clinical trial was conducted on AVNRT patients candidates for radiofrequency ablation (RFA). The patients were randomly assigned to receive isoproterenol (0.5–4 μg/min) or not (control group) for arrhythmia re‐induction after ablation. The results of the electrophysiological (EP) study, the ablation parameters, and the arrhythmia recurrence rate were recorded. We evaluated 206 patients (53 males and 153 females) with a mean (SD) age of 49.87 (15.5) years in two groups of isoproterenol (n = 103) and control (n = 103). No statistically significant difference was observed between the two studied groups in age, gender, EP study, and ablation parameters. The success rate of ablation was 100% in both groups. During ~16.5 months of follow‐up, one patient (1%) in the isoproterenol group and four patients (3.8%) in the control group experienced AVNRT recurrence (HR = 0.245; 95% confidence interval [CI], 0.043–1.418; p = .173). Based on the Kaplan–Meier analysis, there was no significant difference in the incidence rate of arrhythmia recurrence during the follow‐up period between the two studied groups (p = .129). Additionally, there were no significant differences between the arrhythmia's recurrence according to age, gender, junctional rhythm, type of AVNRT arrhythmia, and DAVN persistence after ablation. Although isoproterenol administration for arrhythmia re‐induction after ablation did not alleviate the treatment outcomes and arrhythmia recurrence following RFA in AVNRT patients, further studies with a larger sample size and a longer duration of follow‐up are necessary.

Abstract Background and Aim Non‐alcoholic fatty liver disease (NAFLD) is becoming increasingly prevalent worldwide, and cardiovascular diseases are the most common cause of death in NAFLD patients. The present study aimed to evaluate the possible relationship between the presence and severity of NAFLD and coronary artery disease (CAD). Methods A cross‐sectional study was conducted on 296 patients (122 men and 174 women, with mean age 54.10 ± 9.33 years) referred to the catheterization laboratory of Imam Reza Hospital affiliated to the Mashhad University of Medical Sciences, Mashhad, Iran, for elective coronary angiography to investigate the presence and severity of CAD. Additionally, all patients underwent abdominal ultrasonography (USG) to detect NAFLD and its severity. Results Among the 296 patients, 187 (63.2%) had CAD and 160 (50.1%) had NAFLD. NAFLD patients had significantly higher prevalence of obesity (odds ratio [OR] = 1.047, 95% confidence interval [CI] = 1.002–1.094), hypertension (OR = 1.909, 95% CI = 1.027–3.55), hyperlipidemia (OR = 3.474, 95% CI = 1.862–6.482), and CAD (OR = 2.009, 95% CI = 1.100–3.669).

Abstract Peritoneal adhesion is a significant problem following gastrointestinal surgeries, accompanied by a significant economic burden and morbidity for patients. Punica granatum seed oil (PSO) possesses antioxidative, anti‐inflammatory, and anticancer effects. Thus, we aimed to evaluate the antiperitoneal adhesive properties of PSO in rats. Forty‐eight Wistar rats (200–250 g) were randomly and equally divided into six groups: sham group, control group; peritoneal adhesion without any treatment, vehicle group; peritoneal adhesion with saline + Tween‐80.5% treatment, and experimental groups; peritoneal adhesion with 0.5%, 1.5%, and 4.5% v/v PSO treatment. In addition, peritoneal adhesion was examined macroscopically along with evaluating the oxidative stress (malondialdehyde [MDA], nitric oxide [NO], and glutathione [GSH]) inflammatory (interleukin [IL]‐6, IL‐1β, and tumor necrosis factor‐α [TNF‐α]), fibrotic (transforming growth factor‐β [TGF‐β]), and angiogenic (vascular endothelial growth factor [VEGF]) factors. Our results revealed that the levels of adhesion scores, MDA, NO, IL‐6, TNF‐α, IL‐1β, TGF‐β, and VEGF, were propagated in the vehicle group while the GSH level was alleviated (p

Abstract The association between uric acid (UA) and cardio‐metabolic conditions has been recognized for a long time. However, recently, a body of evidence has highlighted the independent role of UA in a series of conditions, including renal and cardiovascular diseases. In this light, data regarding the prognostic role of UA in acute coronary syndrome (ACS) is scarce. A total number of 100 patients, 59 males and 41 females, diagnosed with ACS were recruited in this study. At the time of admission to the hospital, the serum level of UA was measured. In addition, the HEART score was calculated based on each patients' profile. Participants were on average 61.37 ± 12.08 years old. The most prevalent risk factors were hypertension (48%), a history of coronary artery disease (40%), and diabetes mellitus (33%). The average serum level of UA was 5.81 ± 1.81 mg/dl, and the calculated HEART score had a median of six (minimum of two and maximum of ten). A positive yet statistically insignificant correlation was found between the measured UA level and the calculated HEART score (R = 0.375, p = 0.090). However, further studies with larger sample size are required to assess the direct association of UA level with major adverse cardiac events in patients with cardiovascular disease.

Abstract The trace elements copper (Cu) and zinc (Zn) are essential for maintaining oxidative balance, and cardiac surgery is known to provoke an increase in oxidative stress. We investigated the variations in serum Zn and Cu concentrations before and after surgery in patients undergoing on‐ and off‐pump CABG and heart valve replacement. We performed a prospective study on patients undergoing on‐ or off‐pump CABG, or heart valve replacement surgery (48, 51, and 47 patients, respectively). Venous blood samples were obtained, and serum Cu and Zn concentrations were measured preoperatively, 24 h postoperatively, and the time of discharge. In addition, echocardiography was carried out on all patients before surgery and again on the day of discharge. We found the temporal changes in Cu, Zn, and Zn/Cu ratio were significantly different in all three groups of surgery (p 0.05). In conclusion, the concentrations of Cu and Zn were markedly reduced after on‐ and off‐pump CABG and valve replacement surgery. This may suggest that supplementary Zn and Cu administration could be beneficial during open‐heart surgeries. However, more long‐term studies with more patients are needed to confirm this hypothesis.

Abstract Background and Aims The present study aimed to evaluate the relationship between serum N‐terminal (NT)‐pro‐brain natriuretic peptide (BNP) levels and incidence of left ventricular (LV) systolic and diastolic dysfunction in patients who underwent low‐dose anthracycline chemotherapy. Methods This observational, prospective study was conducted on all patients with proven breast cancer, Hodgkin lymphoma, or non‐Hodgkin lymphoma and no history of previous cardiac or any chronic diseases who were candidates for low‐dose anthracycline chemotherapy from March 2017 to February 2018. We evaluated the serum NT‐proBNP level and performed trans‐thoracic echocardiography at baseline, 6, and 9 months after the chemotherapy. Results Among 57 patients who successfully finished the study, 13 (22.8%) patients were men and 44 (77.19%) patients were women, and the total mean age was 52 ± 14.86 years. Our results revealed that the LV systolic and diastolic function and NT‐proBNP mean levels were in the normal range at all three measured times. Additionally, no significant differences were observed between the levels of NT‐proBNP, LV systolic, and diastolic function at baseline, 6, and 9 months after chemotherapy with low‐dose anthracycline (p = 0.6, 0.1, and 0.4, respectively). Conclusion Following low‐dose anthracycline chemotherapy, none of our patients encountered LV systolic and diastolic dysfunctions and changes in serum NT‐proBNP level. However, further studies with a larger population, longer follow‐up duration, and higher dosage of anthracyclines are required to determine the effects of low‐dose anthracycline on NT‐proBNP level and LV systolic and diastolic functions.

Multiple Sclerosis (MS) is a prevalent inflammatory disease in which the immune system plays an essential role in the damage, inflammation, and demyelination of central nervous system neurons (CNS). The cannabinoid receptor type 2 (CB2) agonists possess anti-inflammatory effects against noxious stimuli and elevate the neuronal survival rate. We attempted to analyze the protective impact of low doses of β-Caryophyllene (BCP) in experimental autoimmune encephalomyelitis (EAE) mice as a chronic MS model. Immunization of female C57BL/6 mice was achieved through two subcutaneous injections into different areas of the hind flank with an emulsion that consisted of myelin Myelin oligodendrocyte glycoprotein (MOG)35–55 (150 µg) and complete Freund’s adjuvant (CFA) (400 µg) with an equal volume. Two intraperitoneal (i.p.) injections of pertussis toxin (300 ng) were performed on the animals on day zero (immunizations day) and 48 h (2nd day) after injection of MOG + CFA. The defensive effect of low doses of BCP (2.5 and 5 mg/kg/d) was investigated in the presence and absence of a CB2 receptor antagonist (1 mg/kg, AM630) in the EAE model. We also examined the pro/anti-inflammatory cytokine levels and the polarization of brain microglia and spleen lymphocytes in EAE animals. According to our findings, low doses of BCP offered protective impacts in the EAE mice treatment in a CB2 receptor-dependent way. In addition, according to results, BCP decreased the pathological and clinical defects in EAE mice via modulating adaptive (lymphocytes) and innate (microglia) immune systems from inflammatory phenotypes (M1/Th1/Th17) to anti-inflammatory (M2/Th2/Treg) phenotypes. Additionally, BCP elevated the anti-inflammatory cytokine IL-10 and reduced blood inflammatory cytokines. BCP almost targeted the systemic immune system more than the CNS immune system. Thus, a low dose of BCP can be suggested as a therapeutic effect on MS treatment with potent anti-inflammatory effects and possibly lower toxicity.

Background: Type-one diabetes (T1D), a chronic autoimmune disease with marked inflammatory responses, is associated with infertility complications and implications. Based on the anti-diabetic, antioxidant, and anti-hyperlipidemic potential of Portulaca oleracea (PO), this study aimed to evaluate the protective effect of this plant extract on streptozotocin-induced type-I-diabetes-associated reproductive system dysfunction and inflammation. Methods: Male rats were randomly divided into four experimental groups: control, diabetic, and treatment/s (PO extract at 100 or 300 mg/kg/daily). Then food and water consumption, body, testis and epididymis weights, histopathological evaluation, seminiferous tubules diameter, sperm count and motility, glucose levels, sex hormones, and inflammatory and oxidative stress markers were evaluated. Results: Our results showed that streptozotocin-induced diabetes significantly increased food and water consumption; increased glucose, MDA, TGF-β1, and TNF-α levels; and decreased the seminiferous tubules diameter, sperm count and motility, levels of LH, testosterone, total thiol, VEGF, and SOD activity. Interestingly, PO extract (phytochemically characterized by using liquid chromatography–mass spectrometry to detect bioactive molecules) significantly ameliorated these parameters and histopathological indexes’ damage in rats. Conclusion. Even if more preclinical assessments are needed to better characterize the mechanism/s of action, the results of this study will pave the way for the rational use of PO on diabetic-associated clinical complications and implications.

Background: Recently, there has been much more interest in the use of medicinal plants in search of novel therapies for human neurodegenerative diseases such as epilepsy. In the present study, we investigated the anticonvulsant effects of Viola tricolor (V. tricolor) on seizure models induced by pentylenetetrazol (PTZ) and maximal electroshock stimulation (MES). Methods: Totally, 260 mice were divided into 26 groups (n=10). Thirty minutes after treatment with the hydroalcoholic extract of V. tricolor (VHE 100, 200, and 400 mg/kg) and its ethyl acetate (EAF 50, 100, and 200 mg/kg) and n-butanol (NBF 50, 100, and 200 mg/kg) fractions as well as diazepam (3 mg/kg), seizure was induced by PTZ (100 mg/kg) or by MES (50 Hz, 1 s and 50 mA). Analysis was performed via ANOVA with the Tukey–Kramer post-hoc test using GraphPad Prism 6.01 (La Jolla, CA). Results: The VHE (400 mg/kg) significantly enhanced latency to the first generalized tonic-clonic seizures (GTCs) induced by PTZ in comparison to the control group (P

Therapeutics. Pharmacology ,RM1-950 - Abstract
Today, with the advances in technology and science, more advanced drug delivery formulations are required. One of these new systems is an intelligent hydrogel. These systems are affected by the environment or conditions that become a gel, stay in the circumstance for a certain period, and slowly release the drug. As an advantage, only a lower dose of the drug is required, and it provides less toxicity and minor damage to other tissues. Hydrogels are of different types, including temperature-sensitive, pH-sensitive, ion change-sensitive, and magnetic field-sensitive. In this study, we investigated a kind of temperature-sensitive smart hydrogel, which has a liquid form at room temperature and becomes gel with increasing temperature. Chitosan-β-glycerophosphate hydrogels have been researched and used in many studies. This study investigates the various factors that influence the gelation mechanism, such as gel formation rates, temperature, pH, time, and gel specificity. Hydrogels are used in many drug delivery systems and diseases, including nasal drug delivery, vaginal drug delivery, wound healing, peritoneal adhesion, ophthalmic drug delivery, tissue engineering, and peptide and protein delivery. Overall, the chitosan-β-glycerophosphate hydrogel is a suitable drug carrier for a wide range of drugs. It shows little toxicity to the body, is biodegradable, and is compatible with other organs. This system can be used in different conditions and different medication ways, such as oral, nasal, and injection.

Pathology ,RB1-214 - Abstract
Objective. Peritoneal adhesion (PA) is an abnormal connective tissue that usually occurs between tissues adjacent to damaged organs during processes such as surgery. In this study, the anti-inflammatory and antioxidant effects of Portulaca oleracea (PO) were investigated against postoperative-induced peritoneal adhesion. Methods. Thirty healthy male Wistar rats (220±20 g, 6-8 weeks) were randomly divided into four groups: (1) normal, (2) control (induced peritoneal adhesion), and (3) and (4) PO extracts (induced peritoneal adhesion and received 100 or 300 mg/kg/day of PO extract for seven days). Finally, macroscopic and microscopic examinations were performed using different scoring systems and immunoassays in the peritoneal lavage fluid. Results. We found that the levels of adhesion scores and interleukin- (IL-) 1β, IL-6, IL-10, tumour necrosis factor- (TNF-) α, transforming growth factor- (TGF-) β1, vascular endothelial growth factor (VEGF), and malondialdehyde (MDA) were increased in the control group. However, PO extract (100 and 300 mg/kg) notably reduced inflammatory (IL-1β, IL-6, and TNF-α), fibrosis (TGF-β1), angiogenesis (VEGF), and oxidative (MDA) factors, while increased anti-inflammatory cytokine IL-10, antioxidant factor glutathione (GSH), compared to the control group. Conclusion. Oral administration of PO improved postoperational-induced PA by alleviating the oxidative factors, fibrosis, inflammatory cytokines, angiogenesis biomarkers, and stimulating antioxidative factors. Hence, PO can be considered a potential herbal medicine to manage postoperative PA. However, further clinical studies are required to approve the effectiveness of PO.

Acute venous congestion leads to blood stasis in the tissue and impaired blood perfusion. Using medicinal leech is an old method for reducing tissue congestion. There are numerous factors in leech saliva and hirudin that have important roles in the leeching beneficial effect. In this study, an animal study was performed to compare leech therapy with heparin therapy in the treatment of acute venous congestion. Thirty male rats were divided into three groups. In the first group, an acute venous congestion was induced at the thigh. Decongestion was performed through the touch of hirudo medicinalis leech. In the second group, heparin sodium was injected, after tourniquet removal. Eventually, no treatment or procedure was performed in the third group after opening of tourniquet. Histopathological and biochemical analysis were performed in these rat. Edema size in heparin therapy and control groups was significantly greater than leech therapy group. Creatine phosphokinase blood level in leech therapy group was significantly lower than the control group, but this difference was unobserved between heparin therapy and control. In contrast, the level of lactate dehydrogenase and aldolase greatly increased in the control group, which received no intervention. Also in histopathological assessment, the level of tissue damage in both heparin and leech therapy groups showed a significant decrease as compared to the control group. Leech therapy can probably be more effective in the reducing of cellular damage caused by acute tissue congestion as compare to heparin therapy.

Genetics ,QH426-470 - Abstract
Peroxisome biogenesis disorders (PBD) are a group of multi-system human diseases due to mutations in the PEX genes that are responsible for peroxisome assembly and function. These disorders lead to global defects in peroxisomal function and result in severe brain, liver, bone and kidney disease. In order to study their pathogenesis we undertook a systematic genetic and biochemical study of Drosophila pex16 and pex2 mutants. These mutants are short-lived with defects in locomotion and activity. Moreover these mutants exhibit severe morphologic and functional peroxisomal defects. Using metabolomics we uncovered defects in multiple biochemical pathways including defects outside the canonical specialized lipid pathways performed by peroxisomal enzymes. These included unanticipated changes in metabolites in glycolysis, glycogen metabolism, and the pentose phosphate pathway, carbohydrate metabolic pathways that do not utilize known peroxisomal enzymes. In addition, mutant flies are starvation sensitive and are very sensitive to glucose deprivation exhibiting dramatic shortening of lifespan and hyperactivity on low-sugar food. We use bioinformatic transcriptional profiling to examine gene co-regulation between peroxisomal genes and other metabolic pathways and we observe that the expression of peroxisomal and carbohydrate pathway genes in flies and mouse are tightly correlated. Indeed key steps in carbohydrate metabolism were found to be strongly co-regulated with peroxisomal genes in flies and mice. Moreover mice lacking peroxisomes exhibit defective carbohydrate metabolism at the same key steps in carbohydrate breakdown. Our data indicate an unexpected link between these two metabolic processes and suggest metabolism of carbohydrates could be a new therapeutic target for patients with PBD.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are classified as two lung complications arising from various conditions such as sepsis, trauma, and lung inflammation. Previous studies have shown that the extract of the leaves of Portulaca oleracea (PO) possesses anti-inflammatory and anti-oxidant activities. In the present study, the effects of PO (50–200 mg/kg) and dexamethasone (Dexa; 1.5 mg/kg) on lipopolysaccharide (LPS)-induced ALI were investigated. Subsequentially, the lung wet/dry ratio; white blood cells (WBC); levels of nitric oxide (NO); myeloperoxidase (MPO); malondialdehyde (MDA); thiol groups formation; super oxide dismutase (SOD) and catalase (CAT) activities; and levels of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, IL-6, IL-10, prostaglandin E2 (PGE2), and transforming growth factor (TGF)-β in the broncho alveolar lavage fluid (BALF) were evaluated in order to demonstrate the anti-oxidant and anti-inflammatory activity of PO. Our results show that PO suppresses lung inflammation by the reduction of IL-β, IL-6, TNF-α, PGE2, and TGF-β, as well as by the increase of IL-10 levels. We also found that PO improves the level of WBC, MPO, and MDA, as well as thiol group formation and SOD and CAT activities, compared with the LPS group. The results of our investigation also show that PO significantly decreased the lung wet/dry ratio as an index of interstitial edema. Taken together, our findings reveal that PO extract dose-dependently displays anti-oxidant and anti-inflammatory activity against LPS-induced rat ALI, paving the way for rational use of PO as a protective agent against lung-related inflammatory disease.
