This study determined the effect of Mango mistletoe Methanolic Extract (MMME) on the cardiac's histopathological profile of hypertensive rats (DOCA-Salt) treated. The MMME was treated on fifty rats for 14 days, divided into five treatments: negative control, positive control, doses 50, 100, and 200 mg/kg BW with five replications. One-way ANOVA analysis was used, namely JAMOVI with version 1.1.9.0, and for cell calculation, diameter using the IMAGE J application. Results showed that there were no significant differences in the histopathological profile of the cardiac in hypertensive rats (DOCA-Salt) treated with MMME for 14 days on the diameter of the heart muscle cells between the control (+) and control groups (-), treatments 1, 2, and 3. This is evidenced by the analysis of p-value> 0.05, namely 0.187 millimeters. Therefore, we concluded that MMME does not affect the diameter of heart/cardiac organ muscle cells. However, there was a significant difference in the amount of necrosis in the cardiac of hypertensive rats between control (+) and control (-) groups, treatments 1, 2, and 3. Based on the results, MMME reduces the number of necrosis in the heart/cardiac organ.

Objective: Our previous studies showed the antihypertensive effect of Ribes khorassanicum (R. khorassanicum), a medicinal herb growing in the North Khorasan Province of Iran. For further evaluation, the present study investigated the effect of n-hexane (HX), ethyl acetate (EA), and aqueous (AQ) fractions of hydroalcoholic R. khorassanicum extract on cardiovascular responses in angiotensin II (AngII) and NG-nitro-L-arginine methyl ester (L-NAME) hypertensive rats. Methods: Wistar rats were randomly divided into 11 groups (n=5): 1) control, 2) AngII (50 ng/kg, i.v), 3) AngII + losartan (10 mg/kg, i.p), 4) L-NAME (10 mg/kg, i.v), 5) L-NAME+ sodium nitroprusside (SNP) (50 mg/kg, i.p), 6,7,8) one dose of each fraction of R. khorassanicum (AQ/EA/HX (50 mg/kg, i.p)) +AngII, and 9,10,11) one dose of each fraction of R. khorassanicum (AQ/EA/HX (50 mg/kg, i.p)) + L-NAME. Treated rats received three fractions 30 min before the injection of L-NAME and AngII in separate groups. The cardiovascular parameters were recorded by the Power Lab instrument via an angiocath inserted into the femoral artery. The peak changes (∆) of mean arterial pressure (MAP), systolic blood pressure (SBP), and heart rate (HR) in treated groups were compared with those of the hypertensive and control groups. Result: AngII and L-NAME significantly increased ∆MAP and ∆SBP and attenuated by pretreatment of LOS and SNP, respectively. Pretreatment with polar (AQ) and semipolar (EA) fractions of R. khorassanicum reduced the peak changes of MAP and SBP in both AngII and L-NAME-treated groups. Only the fraction of the herb attenuated the HR increased in the L-NAME group. The HR in other groups did not demonstrate any significant difference. Conclusion: All fractions of R. khorassanicum have an antihypertensive effect. However, the effect of polar fractions is more salient. It is also conceivable that the antihypertensive effect of fractions is mostly mediated by the inhibition of AngII.

Introduction The aim of this in vitro study was to assess and compare the effect of different intermediary bases on microleakage between tooth and a nanocomposite interface in Class II box cavities in primary teeth. Methods Standard Class II box cavities were prepared in 52 primary molars and randomly divided into 9 groups according to the intermediary base used (Multicore Flow, Fuji II LC, SDR, Smart Dentin Replacement, and Biodentine). All specimens were subjected to thermocycling and prepared for microleakage testing and evaluation. Results There was significant difference in the mean ranks of microleakage between the 9 groups, which was observed in the gingival side (p<0.0001) and the occlusal side (p<0.0001). The mean ranks microleakage was significantly higher with experimental SDR, experimental Multicore Flow, and positive control materials when compared with the other 6 groups. The microleakage mean ranks were statistically significantly lower in experimental Fuji II LC, experimental Biodentine, and all negative control groups when compared with the other 3 groups. Conclusions Microleakage is affected by the application of intermediate material. Experimental Biodentine and Fuji II LC showed the lowest microleakage while experimental SDR and experimental Multicore Flow showed the highest microleakage.

The aim of this randomised, double blind controlled trial was to verify the efficacy of a herbal dentifrice on the reduction of plaque and gingivitis. Forty eight volunteers with established gingivitis were randomly assigned to either a test group (herbal dentifrice) or positive control group (dentifrice with triclosan and fluoride). The dentifrices were distributed in plain white tubes by an independent pharmacy, which revealed the contents of each tube only after the experimental period. Plaque and gingivitis assessments were carried out on baseline and after 28 days of product use. All examinations were conducted by the same calibrated investigator. Subjects were instructed to brush their teeth three times daily using their assigned dentifrice for 28 days. There was a significant reduction in plaque levels in both the test and control groups. However, there was no significant difference between the groups. A significant reduction in gingivitis was observed in both groups, although there was no significant difference between them. No adverse reactions were reported. The authors concluded that both dentifrices were effective in reducing plaque and gingivitis in subjects with established gingivitis.

Abstract Purpose Peripheral neuropathy is a complication of taxane that in severe cases can limit the optimal treatment. The aim of this study was to evaluate the efficacy of memantine in prevention of docetaxel induced peripheral neuropathy in patients with breast cancer. Methods In this randomized clinical trial, 40 women between the ages of 18 and 64 years with non-metastatic breast cancer (stages I to III) were included (registry number: IRCT20160310026998N9 and registry date: 26 March 2019). All patients were treated with the AC-T regimen (with docetaxel). Patients in intervention group received memantine at a dose of 20 mg for 8 weeks at the beginning of the first cycle of docetaxel. Patients in control group did not take any medication for neuropathy prevention. To assess the neuropathy, DN4 and CTCAE questionnaires were used at baseline, one months, three months and six months after the intervention. Results The DN4 questionnaire score was remarkably less in memantine group in follow up one (p-value: 0.033) and three (p < 00.1). The CTCAE follow up score did not change during study. The Neuropathy duration and Neuropathy onset, were shown significant difference between the intervention and control groups, p = 0.050 and p = 0.001, respectively. From 40 patients, 8 (40%) in memantine group and 2 (10%) in control group, did not experience any kind of neuropathy. Conclusion Data showed that prophylactic administration of memantine 20 mg/day has been effective in prevention of severity and incidence of docetaxel induced neuropathy in patients with breast cancer.

Abstract Background The menace of resistance to anti-malarial drugs is a great challenge to malaria control, necessitating the search for new anti-malarial agents. This search has led to the exploration of natural products for efficacy in malaria therapy. Omidun is the supernatant of fermenting maize (ogi) slurry that has been widely investigated and reported to possess several health benefits and it is used traditionally as solvent for preparing anti-malarial herbs. However, there is no information on the anti-malarial activity of omidun itself. This study was conducted to investigate the prophylactic, curative and suppressive anti-malarial potential of omidun. Methods Experimental mice in the curative group were infected with 1 × 106 cells of Plasmodium berghei strain ANKA and treated with either 0.2 ml of omidun containing 3 × 109 cfu/ml of viable lactic acid bacteria or 0.2 ml of 5 mg/kg of chloroquine (positive control) or 0.2 ml of saline (negative control) for 4 days from day 3 post infection. The prophylactic group of mice were pre-treated with either omidun, chloroquine or saline for 4 days before infection with P. berghei, while the suppressive group was treated with omidun or chloroquine or saline and infected with P. berghei simultaneously. A group of mice were uninfected but treated (with omidun and control samples), while a final group was uninfected and untreated (controls). Parasitaemia and histopathology analysis were done in all groups. Results The curative and suppressive groups showed a significant difference between the omidun-treated mice (100% parasitaemia reduction) and the untreated mice (54.5% parasitaemia increase). There was no significance difference between the omidun treatment and chloroquine (positive control) treatment in suppressive group as both treatment had 100% parasitaemia reduction. The omidun prophylactic treatment however did not show any parasitaemia suppression, but a significant difference was observed between the omidun treatment (85% increase) and the chloroquine (positive control) treatment (100% reduction) in the group. Omidun treatment is non-toxic to the kidney. Conclusion This study provides scientific evidence supporting omidun usage in the treatment of malaria. Consequently, further work may yield the specific component of omidun responsible for the anti-malarial activity.

Diabetes is a metabolic disease that can affect the male reproductive system. The condition of hyperglycemia will increase the production of ROS, causing oxidative stress. Oxidative stress causes microangiopathy, triggers cell apoptosis, interferes with spermatogenesis, thereby affecting the diameter of the seminiferous tubules. Kebar grass contains of flavonoid and vitamin E which can be used to reduce ROS reactions and inhibit oxidative stress. This research was to prove that kebar grass extract can increase diameter of the seminiferous tubules of diabetic mice. Total of 30 samples were divided into 5 groups: negative control group (K-) was given CMC-Na, positive control group (K+) was given metformin 2mg/kg, groups P1, P2 and P3 received 2mg/kg metformin and kebar grass extract with different dosages (67.5mg/kg, 135mg/kg and 270mg/kg). The treatment lasted for 35 days. On the 36th day the mice were sacrificed and the testes were taken, then histological observations were made with HE staining to measure the diameter of tubules. The result showed that there was a significant difference in the diameter of seminiferous tubules with p value=0,000. Kebar grass extract can increase the diameter of seminiferous tubules of diabetic mice.
