To minimize the incidence and mortality of cancer, dye trace method was used to explore the mechanism of drug inhibition. 60 mice were selected as the research objects and randomly divided into five groups model group, shikonin group, aconitine group, notoginsenoside R1 group, and compound group. When establishing the model, begin to administrate the medicine by gavage. The permeability of lung barrier was measured, and H.E staining, immunohistochemical staining, and Western blot test were carried out. The results showed that the mice in model group had decreased autonomic activity, increased permeability of the lung barrier, white nodules on the lung tissue, decreased protein expression related to cell proliferation and differentiation, and decreased protein expression associated with cell proliferation and differentiation, increased expression of related proteins in cancer stem cells, and low level of cell-linked communication. And the incidence of lung cancer in the model group mice was 100%. The histopathological changes in mice were improved to varying degrees after the intervention of the three drugs. Especially in the compound group, the incidence of lung cancer decreased to 8.3%. This study demonstrated that the combination of shikonin, aconitine and notoginsenoside R1 had a good anti-cancer effect, which provided a theoretical basis for clinical research. © 2020 The Authors.Prostate cancer (PCa) has a variable biological potential. It constitutes the second most common cancer amongst men worldwide and the fifth most common cancer in Saudi Arabia. Identifying men at higher risk of developing PCa, differentiating indolent from aggressive disease and predicting the likelihood of progression will improve decision-making and selection for active surveillance protocols. check details Biomarkers have been utilized for PCa screening and predicting cancer behavior and response to treatment. The prostate specific antigen (PSA) screening helps detect PCa in early stages, while implementing a plan for management and outcome. However, PSA screening is still controversial, due to the risks of over diagnosis and treatment, and its inability to detect a good proportion of advanced tumors. Alternatively, a new era of PCa biomarkers has emerged with higher PCa specificity than PSA and its isoforms hopefully improving screening methods, such as Prostate Health Index (PHI) score, Progensa Prostate Cancer Antigen 3 (PCA3), Mi-Prostate Score (MiPS), Prostate Stem Cell Antigen (PSCA), 4Kscore test, and Urokinase Plasminogen Activation (uPA and uPAR). Few novel biomarkers have shown promise in preliminary results. This review will display promising biomarkers including some important FDA approved ones, highlighting their clinical implication and future place in the PCa puzzle, along with addressing their current limitations. © 2020 The Author(s).Discovery of potential bioactive metabolites from sponge-associated bacteria have gained attraction in recent years. The current study explores the potential of sponge (Suberea mollis) associated bacteria against bacterial and fungal pathogens. Sponge samples were collected from Red sea in Obhur region, Jeddah, Saudi Arabia. Of 29 isolated bacteria belong to four different classes i.e. Firmicutes (62%), γ-Proteobacteria (21%), α-Proteobacteria (10%) and Actinobacteria (7%). Among them nineteen (65%) bacterial strains showed antagonistic activity against oomycetes and only 3 (10%) bacterial strains were active against human pathogenic bacteria tested. Most bioactive genera include Bacillus (55%), Pseudovibrio (13%) and Ruegeria (10%). Enzyme production (protease, lipase, amylase, cellualse) was identified in 12 (41%) bacterial strains where potential strains belonging to γ-Proteobacteria and Firmicutes groups. Production of antimicrobial metabolites and hydrolysates in these bacteria suggest their potential role in sponge against pathogens. Further bioactive metabolites from selected strain of Vibrio sp. EA348 were identified using LC-MS and GC-MS analyses. We identified many active metabolites including antibiotics such as Amifloxacin and fosfomycin. Plant growth hormones including Indoleacetic acid and Gibberellin A3 and volatile organic compound such as methyl jasmonate were also detected in this strain. Our results highlighted the importance of marine bacteria inhabiting sponges as potential source of antimicrobial compounds and plant growth hormones of pharmaceutical and agricultural significance. © 2020 The Authors.The ZnO particle with varieties of morphology was prepared from ice-cube of zinc ammonium complex at boiling water surface in 1 min induction of thermal shock. The zinc ammonium complex in ice cube was developed using zinc acetate and biologically activated ammonia in 1 hr and kept in the freezer. Temperature gradient behaviour of the water medium during thermal shock was captured by the thermal camera and thermometer. Morphology study revealed a variety of flower-like ZnO particles with variable size from 1.0 to 2.5 μm. Further, ZnO particle morphologies were tuned by adding trisodium citrate and hexamine to obtain uniform spherical (2-3 μm) and flower (3-4 μm) shapes, respectively. XRD patterns revealed that all ZnO samples are of a hexagonal structure. Photocatalytic inactivation of E. coli has been investigated using various particle morphologies of ZnO in an aqueous solution/overcoated glass slide under sunlight. The photo-inactivation of E. coli by ZnO particles in suspension condition was better when compared to a coated glass slide method. AFM study confirmed the destruction of bacterial cell wall membrane by the photocatalytic effect. The particles morphology of photocatalyst is well dependent on antibacterial activity under sunlight. © 2020 The Author(s).The phenomenal increase in the demand of herbal drugs, leads to over exploitation of medicinal plants which ultimately resulted in the scarcity and endangerment of many valuable plant species. On observing the difficulties in procuring genuine herbal drugs arose the concept of substitution which was documented in many classical Ayurvedic texts. The present study made a comparative evaluation of the gastroprotective potential of hydroalcoholic extracts of an original drug Aconitum heterophyllum (HAAH) and its substitute Cyperus rotundus (HACR) in the treatment of gastric ulcer under in vivo experimental conditions. The anti-ulcer property of the plant extracts was investigated against pylorus ligation induced ulcer in Wistar albino rats. The results confirmed that both A. heterophyllum and C. rotundus deliver comparable significant protection against gastric ulcer, indicated by a decrease in the free and total acidity, volume of gastric content, total proteins and increase in pH of gastric content, total carbohydrates and total carbohydrates to total proteins ratio.
