Cancer is one of the deadliest diseases in the world. Cancer may occur due to gene mutation. Rhaphidophora pinnata is a plant that has many benefits, especially in the leaves which have been used traditionally to treat cancer. The aim of this research is to test the antimutagenic activity of nanoparticles R. pinnata using the micronucleus method. The mice were induced with cyclophosphamide and then followed with the administration of nanoparticles of R. pinnata at the doses of 50, 100, 200 mg/kg for 7 days. The antimutagenic activity was evaluated at the decrease in the number of micronucleus in 200 polychromatic erythrocytes (PCE) cells of mice bone marrow. The result showed that the reduction of amount of micronucleus in PCE of a negative control group, treatment groups, and normal group is 22.65%, 60.3%, 79.6%, 93.8%, and 100%. These results indicate that the antimutagenic activity of nanoparticle of R. pinnata increases proportionally as the doses were increased. It can be concluded that nanoparticles R. pinnata at the doses of 50, 100, and 200 mg/kg have antimutagenic activity.Rice husk nanosilica contains hydroxyl for dentin remineralization. The aim of this study was to analyze and correlate the ability of rice husk nanosilica to induce hydroxyapatite dentin. The detachment of hydroxyl from rice husk nanosilica was analyzed using the sol-gel and pyrolysis methods with Fourier transform infrared spectroscopy. Subsequently, exposing of the demineralized dentin to rice husk nanosilica was performed for a comparison. The formation of hydroxyapatite on dentin was analyzed using X-ray diffraction. The amount of hydroxyl released from the two methods was then correlated with the hydroxyapatite that formed at the dentin. The extraction of hydroxyl on rice husk nanosilica with two methods was the same. Analysis of the amount of hydroxyapatite dentin with both the methods corresponds to each other. The correlation test obtains the value of R = 0.656. Rice husk nanosilica has a similar capability to release hydroxyl compound and form hydroxyapatite dentin using two methods. The creation of hydroxyapatite dentin is not only caused by the exposure of rice husk nanosilica but also owing to other factors that might reinforce the process of hydroxyapatite formation.This study aims to investigate the potential of bioactive secondary metabolites contained in Sphagneticola trilobata (L.) J.F Pruski leaves as novel plant-derived anticancer agent. Qualitative bioactive compound contents in the methanolic extract of S. trilobata leaves were screened using phytochemical method. Antioxidant evaluation was carried out using 2,2-diphenyl-1-picrylhydrazyl assay; antibacterial – using well diffusion method on Escherichia coli and Salmonella typhi; and cytotoxicity – using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay on MCF-7 cell line and Vero Cell. It was found that the methanolic extract exhibited antioxidant activity with an IC50 value of 124.34 μg/mL. The inhibition zone values against E. coli and S. thypi (at extract concentration of 100 mg/mL) were 34.33 and 36 mm, respectively. In vitro MTT assay showed that our extract successfully reached 96% mortality with LC50 = 189.287 μg/mL, where the selective index of 2.5 suggest its selectivity against MCF-7 breast cancer cell line. In conclusion, the data of biological activities suggest the potential development of methanolic extract from S. trilobata leaves as a phytomedicine for breast cancer treatment.Search for an effective and safe vaccine to prevent transmission of current pandemic is an unmet need. This study reviews and compares the available early phase clinical data of vaccine candidates which have reached phase 3 of clinical development. The latest update of „DRAFT landscape of coronavirus (CoV) disease 2019 candidate vaccines (October 2, 2020)” released by the World Health Organization was accessed to identify the potential vaccine candidates. The full text articles (published and/or preprint) of data of early clinical trials of the selected vaccines were accessed from the links provided in the same document, PubMed and/or medRxiv.com. After extraction and synthesis, the data were critically evaluated for the study efficacy and safety outcomes. Of the total 193 candidate vaccines 10 were found to reach phase 3 of the clinical development. Nine of these were included in the evaluation process. In all of the included studies, immunogenicity and serious adverse events/local or systemic adverse events/laboratory parameters abnormality was considered as efficacy and safety outcomes respectively. Immunogenicity response with most of the vaccines was either higher than or similar to the respective controls except one (recombinant adenovirus type 26 COV2 [Ad26.COV2.S]) for which it was less than that in control. Overall adverse events (related and/or unrelated) were more with vaccines than those with respective control(s) in three studies, in other two, these were similar whereas in one study, the events were less in the vaccine group than in control group and in the rest, data described were descriptive only without any mention for the same for the control. In conclusion all studies showed immunogenic response to target protein of severe acute respiratory syndrome CoV-2 and which was higher than the respective control except for Ad26.CoV2.S. Many of the vaccines caused more adverse events than the controls, however most were mild and transient and/or manageable.Intraplacental choriocarcinoma (IC) is a rare disease, occurring in approximately 1 in 50,000 pregnancies. A 33-year-old woman, gravida 2 para 0, sustained an intrauterine fetal death due to fetomaternal haemorrhage (FMH) at 36 weeks of gestation after presenting with decreased fetal movements in the days prior. The placenta macroscopically appeared normal. However, histological examination revealed an intraplacental choriocarcinoma. Assessment of this woman’s quantitative beta human chorionic gonadotropin (bHCG) level was negative and a computerized tomography scan of her chest, abdomen and pelvis revealed no metastatic disease yet a bulky uterus. After discussion at a multidisciplinary tumour board meeting, the patient had endometrial curettings to rule out any uterine pathology and serial bHCG tests until one year post-partum. Following this, the patient successfully carried and delivered a live female term infant. Although FMH is a rare clinical manifestation of IC it should always alert clinicians to investigate the cause further, through urgent and careful histopathological examination of the placenta. This will allow for appropriate management with chemotherapy if indicated and a reduction in maternal morbidity and mortality.Over time, diabetes patients usually need combination therapy involving two or more agents, including phytonutrients to attain therapeutic targets. The purpose of this research is to elucidate the combined effect of metformin and gallic acid (GA) on glucose metabolism, inflammation as well as oxidative and endoplasmic reticulum (ER) stresses in fructose-fed diabetic rats. Thirty-five rats of Wistar strain were arbitrarily distributed into five groups, each containing seven animals as follows normal control, diabetic control, groups administered 100 mg/kg bw metformin only, 50 mg/kg bw gallic acid only and a combination of both. Experimental animals were made diabetic by single injection of 40 mg/kg streptozotocin (intraperitoneally) subsequent to 14 days administration of 10 % fructose prior. Treatment of rats continued for 21 days following diabetes confirmation. Glucose and insulin levels as well as lipid profile were evaluated in the serum, while activities of catalase and superoxide dismutase were estimated in both liver and pancreas. In addition, levels of malondialdehyde, interleukin-6 and tumor necrosis factor-alpha, as well as expression of activating transcription factor-4 were evaluated in liver and pancreas of diabetic rats. Activities of glucose-6-phosphatase and glucokinase were also determined in liver of diabetic animals. Metformin only, GA only and combination of metformin and GA significantly improved antioxidant status and glucose homeostasis while inflammation and endoplasmic reticulum stress were significantly ameliorated in diabetic rats. Metformin/GA combination appeared to improve glucose metabolism by increasing insulin level and ameliorating the dysregulated activities of glucose metabolizing enzymes and ER stress better than either metformin only or GA only. It could be concluded that coadministration of metformin/GA produced a combined effect in ameliorating diabetes in Wistar rats and could be considered in treatment of diabetes.The AuNPs have been used in biomedicine as therapeutic tools for cancer. However, its role in the context of respiratory physiology has been little studied. This study aimed to determine the impact of AuNPs on respiratory smooth muscle tone, using a model of isolated tracheal rings from female and male rats precontracted with acetylcholine (ACh). AuNPs exerted a contractile effect only in the concentration of 100 ug/ml. This contractile effect was not modified by gender. The possible mediator +could be nitric oxide (NO), measured in a physiological solution containing the tracheal rings treated with different concentrations of AuNPs. The results obtained in this study show that the AuNPs are bio-inert in a concentration range of 0.1-10 μg/mL; however, 100 μg/mL could trigger airway hyperresponsiveness. Similar effects were obtained in isolated trachea rings treated with 100 μg/mL HAuCl4. An evaluation of HAuCl4 in physiological buffer at various HEPES concentrations (0-20 mM) showed the formation of AuNPs that could explain the contractile effect on the tracheal smooth muscle.A 36-year-old male patient is referred for urology review for haematuria following cyclophosphamide and mesna administration for allogeneic stem cell transplant for treatment of acute lymphoblastic leukaemia. Severe haematuria continued despite multiple interventions including continuous bladder irrigation and cystoscopic fulguration, with formation of consolidated clot in the bladder. A successful cystotomy for removal of clot and initiation of alum was performed, leading to resolution of haematuria.Within the text we describe a 66-year-old male with a history of prostate cancer (PCa), incidentally found to have left-sided hydronephrosis and a left ureteral lesion. Ureteroscopy was employed to visualize the lesion, a biopsy was taken, and a double J stent was placed. The lesion was of prostatic origin and the patient was subsequently started on androgen deprivation therapy (ADT). 6 months following the procedure, the patient’s PSA had decreased and his hydronephrosis had resolved. We are the first to report treating a ureteral metastasis from PCa and its associated hydronephrosis solely with ADT and double J stenting, respectively.Locally advanced prostate cancer can extend into the pelvis, and can also invade the bladder and rectum. We encountered a patient with prostate cancer that exhibited severe local invasion, protruding into the perineum. Distant metastasis was absent, despite the large tumor size. The tumor bled and caused difficulty sitting and standing, compromising the patient’s quality of life. Total pelvic exenteration and chemotherapy were considered, but the patient’s general condition rendered these therapies inappropriate. However, of the limited treatment options available given the patient’s condition, palliative irradiation of the protruding region proved effective.
