Methods: Flow cytometric analysis was used to measure the cytotoxicy. Alkaline phosphatase activity was detetmined using p-nitrophenyl phosphate as a substrate. Calcium deposition was detected using alizarin red staining along with osteogenic marker expression in preosteoblast MC3T3E1 cells. In addition, vertebral formation in zebrafish larvae was detected using calcein staining and osteogenic gene expression. Results: AEPB highly promoted the expression of osteogenic markers including runt-related transcription factor 2, osterix, and alkaline phosphatase, along with elevated levels of mineralization in MC3T3-E1 cells. Moreover, AEPB accelerated vertebral formation in zebrafish larvae accompanied by upregulated expression of osteogenic genes. FH535, an inhibitor of Wnt/β-catenin, suppressed AEPB-induced osteogenic gene expression and vertebral formation, indicating that AEPB stimulates osteogenesis by activating the Wnt/β-catenin signaling pathway. Conclusions: AEPB stimulates osteoblast differentiation and bone formation by activating β-catenin. Therefore, AEPB is a promising material that induces osteogenesis, and is useful for the treatment of bone resorption diseases.","PeriodicalId":8560,"journal":{"name":"Asian Pacific journal of tropical biomedicine","volume":"12 1","pages":"115 - 123"},"PeriodicalIF":1.7,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45422292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

NAFLD is set to be the most common etiology of serious liver diseases in numerous nations when accompanied by obesity and type 2 diabetes. It is further histologically categorized into the non-alcoholic fatty liver (NAFL; steatosis without hepatocellular injury) and non-alcoholic steatohepatitis (NASH) which is characterized by the coexistence of hepatic steatosis and inflammation and is accompanied by hepatocyte injury (ballooning), either with or without fibrosis. NAFL is considered the benign and reversible stage arising from the excessive accumulation of triglycerides in hepatocytes. However, NASH is a more progressive stage of NAFLD, due to the increased risks of evolving more serious diseases such as cirrhosis, hepatocellular carcinoma. This concept, however, has been lately challenged by a hypothesis of multiple parallel hits of NAFLD, in which steatosis and NASH are separate entities rather than two points of the NAFLD spectrum, not only from a set of histological patterns but also from a pathophysiological perspective. The current review highlights the epidemiology and pathophysiology of NAFLD, and its progression towards steatohepatitis, with special focus on the novel imminent therapeutic approaches targeting the molecular aspects and the pathogenic pathways involved in the development, and progression of NAFLD.","PeriodicalId":8560,"journal":{"name":"Asian Pacific journal of tropical biomedicine","volume":"12 1","pages":"99 - 114"},"PeriodicalIF":1.7,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43544447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Sodium dodecyl sulphate polyacrylamide gel electrophoresis and reverse-phase high-performance liquid chromatography techniques were employed for protein characterization. Antioxidant activity of PEKS was assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. The protective effect of PEKS on sodium nitrite (NaNO2) induced oxidative stress was evaluated using the in vitro red blood cell model, while the effect of PEKS on diclofenac-induced oxidative stress was examined in vivo in rats. Platelet-rich plasma and platelet-poor plasma were used for anticoagulant and antiplatelet activities of PEKS. Results: PEKS revealed similar protein bands on SDS-PAGE under reduced and non-reduced conditions. Several acidic proteins were present in native PAGE. PEKS showed antioxidant properties by scavenging DPPH with an IC50 of 24.58 μg. PEKS exhibited a protective effect on NaNO2 induced oxidative stress in red blood cells by restoring the activity of stress markers. In addition, PEKS alleviated diclofenac-induced tissue damage of the liver, kidney, and small intestine. PEKS showed an anticoagulant effect in both in vivo and in vitro experiments by enhancing normal clotting time. PEKS did not affect prothrombin time but increase activated partial thromboplastin time. Furthermore, PEKS inhibited adenosine diphosphate and epinephrine-induced platelet aggregation. Conclusions: PEKS protects tissues from oxidative stress and exhibits antithrombotic activity.","PeriodicalId":8560,"journal":{"name":"Asian Pacific journal of tropical biomedicine","volume":"12 1","pages":"47 - 58"},"PeriodicalIF":1.7,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43978489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The normal control and the intoxicated groups received normal saline, and the standard group received imipramine, while the remaining groups received 100, 300, and 500 mg/kg Glinus lotoides ethanolic extract. All groups received treatments for 14 d. Lipopolysaccharides (LPS) were then administered i.p. (0.83 mg/kg) to all groups except the normal control group. After 24 h, anxiety and depression-like behaviors were evaluated by performing behavioral analysis (open field, tail suspension, forced swim, sucrose preference test), and determining total oxidant status, total antioxidant capacity, catalase, and biochemical parameters [malondialdehyde, glutathione, superoxide dismutase, tumor necrosis factor (TNF)-alpha and interleukin (IL)-6]. Results: Phytochemical studies confirmed the presence of phenols and flavonoids and HPLC analysis showed the presence of gallic acid, quercetin, chlorogenic, and caffeic acid. Total oxidant status was significantly decreased, while total antioxidant capacity was significantly increased in the Glinus lotoides ethanolic extract treated groups.

Methods: The extract was obtained from the fermentation of B. humi and fractionation of the crude extract was conducted via column chromatography. Cytotoxicity of the B. humi extract was determined by using MTT assay and real-time cellular analysis. Morphological changes, cell cycle profiles, mode of cell death, and caspase expressions of control and treated breast cancer cells were determined. Results: The ethyl acetate extract isolated from B. humi was cytotoxic against MCF-7 and MDA-MB-231 cell lines. One of the dichloromethane (DCM) fractions, designated as DCM-F2, exhibited the strongest activity among all the fractions and thereby was selected for further studies. DCM-F2 had selective cytotoxicity on target cells by inducing apoptosis, particularly in the early stage, and cell cycle arrest. Treated cells caused inhibition of cell cycle progression at 72 h leading to a significant increase (P < 0.05) in the G0/G1 population. DCM-F2 treated MDA-MB-231 cells showed caspase-dependent apoptosis, whereas DCM-F2 treated MCF-7 cells showed a caspase-independent apoptosis pathway. Five compounds were successfully isolated from B. humi. Cyclo (Pro-Tyr) was the most cytotoxic and selective compound against MCF-7 cells.

Methods: Nanoprecipitation approach was successfully used for the formulation of nanosuspension. To obtain pharmaceutical-grade nanosuspension with minimum particle size and polydispersity index, sodium lauryl sulphate was selected as a stabilizer. Important formulation parameters were statistically optimized by the response surface methodology approach. The optimized nanosuspension was subjected to stability and in vitro dissolution testing and characterized by scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, and zeta sizer. To evaluate the preeminence of nanosuspension over coarse suspension, comparative bioavailability studies were carried out in male albino rats. The pharmaceutical potential of developed nanosuspension was evaluated by antioxidant, antimicrobial, and toxicity studies. Results: The optimized nanosuspension showed an average particle size of 275.5 nm with a polydispersity index and zeta potential value of 0.415 and -48.8 mV, respectively. Atomic force microscopy revealed that the average particle size of nanosuspension was below 100 nm. The formulated nanosuspension showed better stability under refrigerated conditions. Nanosuspension showed an improved dissolution rate and a 2.14-fold greater plasma concentration of quercetin than coarse suspension. Moreover, the formulated nanosuspension exhibited enhanced antioxidant and antimicrobial potential and was non-toxic.
