Abstract
Curcumin is a naturally polyphenolic compound used for hepatoprotective, thrombosuppressive, neuroprotective, cardioprotective, antineoplastic, antiproliferative, hypoglycemic, and antiarthritic effects. Kidney disease is a major public health problem associated with severe clinical complications worldwide. The protective effects of curcumin against nephrotoxicity have been evaluated in several experimental models. In this review, we discussed how curcumin exerts its protective effect against renal toxicity and also illustrated the mechanisms of action such as anti-inflammatory, antioxidant, regulating cell death, and anti-fibrotic. This provides new perspectives and directions for the clinical guidance and molecular mechanisms for the treatment of renal diseases by curcumin.

Abstract
Averrhoa carambola L. presents in its composition diversity of nutrients and vitamins. The present study aimed to extract water and fat-soluble compounds from this fruit at different stages of maturation (green and mature), perform the physical-chemical characterization as well as evaluate its cytotoxicity against hepatoma cells of Rattus norvegicus (HTC). The physicochemical results showed that the pH and molar acidity is influenced by the fruit maturation state. The fruit presented high percentage of moisture, while the percentage of total minerals (ash) increased according to its maturation stage. The results of the phytochemical screening showed that star fruits present phenolic compounds. The antioxidant activity showed greater potential for the ethanolic extracts of the green and mature star fruit. For HTC cells treated with ethanolic extract of green and mature star fruit the data show absence of cytotoxic effect. The tests with the aqueous extract showed cytotoxic/antiproliferative effect of green and mature star fruit extract, in 24, 48 and 72 hours. The presence of nutraceutical compounds and the cytotoxic/antiproliferative activity were more expressive in the aqueous extract, being an option of easily accessible solvent economic and not harmful to organisms.

Abstract
Objectives In Turkey, the genus Moltkia Lehm. is represented by two species, namely Moltkia aurea Boiss. and M. coerulea (Willd.) Lehm., which are used as both food and for medicinal purposes. This study aimed to evaluate the antidiabetic and antioxidant potential and phytochemical profiles of leaf, flower, and root extracts of Moltkia species. Materials and Methods α-Glucosidase and α-amylase inhibitory activities, antioxidant effects, and total phenol and flavonoid contents of Moltkia extracts were evaluated. High-performance liquid chromatography was performed for identifying and quantifying phenolic compounds, which are responsible for various activities of these extracts. Results Among the investigated phenolic compounds, caffeic and rosmarinic acids and rutin were determined and quantified in methanol extracts. Rutin was the major compound in the flower extract of M. aurea. Rutin and rosmarinic acid were the major compounds in the leaf extract of M. aurea. The flowers, leaves and roots of M. coerulea were also rich in rosmarinic acid. The antioxidant and antidiabetic potential of these extracts may be attributable to their rutin and rosmarinic acid content. Conclusion Moltkia species can be used as natural sources of antioxidants. Notably, M. aurea extracts can be used for the development of herbal products with antidiabetic potential.

Abstract
This study was conducted to design and evaluate a wound dressing based on a polycaprolactone (PCL) nanofiber coated with gamma oryzanol (GO) and chitosan (CS) in mice model. All the dressings were prepared by electrospinning method, and their morphology and physical properties were investigated. The mice were divided into five groups and treated with I) PCL-sole (PCL), III) PCL-mupirocin (PCL-M), IV) PCL-GO, IV) PCL-CS, and V) PCL-CS-GO. Wound area, total bacterial count, histopathological parameters, and expressions of IL-1β, TNF-α, IL-10, MMP-9, EGF, and VEGF were assessed. The fibers were randomly distributed in PCL group, but loading CS and GO increased the complexity and placing on the dressings. PCLs loaded with GO and CS showed lower viscosity, surface tension, and fiber diameter and higher conductivity and water contact angle compared to unloaded PCLs (P < 0.05). The treatment with PCLs loaded with mupirocin, CS, and GO significantly reduced wound area and total bacterial count (P < 0.05). Loading PCLs with mupirocin, CS, and GO decreased the expressions of IL-1β, TNF-α, MMP-9, but increased the expressions of IL-10 and VEGF compared to the unloaded PCL group (P < 0.05). The most optimal responses to wound healing and physical parameters belonged to the PCL-CS-GO group.

Abstract
We investigated the wound healing effects of an ointment prepared from a hydroethanolic extract of Trifolium pratense (red clover) in Wistar rats. An animal model was prepared by making 314 mm2 full thickness skin excisions in all animals. Rats were divided into four experimental groups. Group 1 was a non-intervention control. Groups 2, 3 and 4 were treated topically with ointments containing 1.5, 3.0 and 6% (w/v) T. pretense extract, respectively. We evaluated the effects of these ointments by histological analysis of collagen production, epidermis thickness, fibroblast distribution and wound contraction ratio, and also by estimating expression of Bax, Bcl-2 and p53. Collagen production, epidermis thickness, fibroblast distribution and wound contraction ratio were significantly increased in groups 2 - 4 compared to group 1. Groups 2 - 4 also exhibited significantly increased levels of Bcl-2 mRNA and reduced mRNA levels of Bax and p53 compared to group 1. Groups 2 - 4 exhibited accelerated healing by up-regulating Bcl-2 expression, reducing p53 and Bax levels, and by promoting the proliferative phase of healing. We suggest that a hydroethanolic extract of T. pratense in commercial ointments may be useful for promoting wound healing.

Abstract
This study aims to evaluate the effects of topical sole and co-administration of Platelet-rich plasma (PRP) and chitosan on the infected burn wounds model by Candida albicans in Wistar rats. A circle partial thickness contact burn wound model occurred via brass a size of 8mm diameter between the shoulders and after that, 50μl of a suspension containing C. albicans yeast (5×107) colony forming unit was poured on the surface of the wound. The experimental groups included Control, Clotrimazole, PRP and Chitosan+PRP that received any agent, Clotrimazole®, PRP and Chitosan+PRP to treat the wound, respectively. To assess the healing rate, wound size rate, tissue yeast count (TYC) and immunohistochemical staining for heat shock protein 70 (HSP70), HSP 90 and proliferating cell nuclear antigen (PCNA) were conducted. Moreover, enzymatic activity of glutathione peroxidase (GPx), superoxide dismutase (SOD) and malondialdehyde (MDA) rate were evaluated. The results demonstrated that the co-administration of Chitosan+PRP drastically (P<0.05) decreased the wound size and TYC rate comparing to other groups (P<0.05). Immunohistochemical results for HSP 70, HSP 90 and PCNA showed positive reactions and increased intensity in all the treated groups comparing to the control group. Activities of GPx and SOD were higher and the level of MDA was lower all treated groups compared to the control group. A topical use of PRP and chitosan can be advantageous in the infected burn wounds healing.

Abstract
BACKGROUND Epithelial-to-mesenchymal transition (EMT) is involved in tumor progression, invasion, migration and metastasis. EMT is a process by which polarized epithelial cells acquire motile mesothelial phenotypic features. This process is initiated by disassembly of cell-cell contacts through the loss of epithelial markers and replacement of these markers by mesenchymal markers. Reconstruction of the cytoskeleton and degradation of the tumor basement membrane ensures the spread of invasive malignant tumor cells to distant locations. Accumulating evidence indicates that curcumin, as a well-known phytochemical, can inhibit EMT/metastasis through various mechanisms and pathways in human tumors. CONCLUSIONS In this review, we summarize the mechanisms by which curcumin may affect EMT in cells under pathological conditions to understand its potential as a novel anti-tumor agent. Curcumin can exert chemo-preventive effects by inhibition and reversal of the EMT process through both TGF-β-dependent (e.g. in hepatoma and retinal pigment epithelial cancer) and -independent (e.g. in oral cancer, colorectal cancer, pancreatic cancer, hepatocellular carcinoma, breast cancer, melanoma, prostate cancer, bladder cancer, thyroid cancer and lung cancer) pathways. Curcumin can also mitigate chemoresistance through EMT suppression and promotion of the antiproliferative effects of conventional chemotherapeutics. Therefore, curcumin has the potential to be used as a novel adjunctive agent to prevent tumor metastasis, which may at least partly be attributed to its hampering of the EMT process.

Abstract
Curcumin has exhibited a protective effect against development of renal fibrosis in animal models, however, its underlying molecular mechanisms are largely unclear. Therefore, we investigated the anti-fibrosis effects of curcumin in transforming growth factor-β1 (TGF-β1)-induced epithelial-to-mesenchymal transition (EMT), and the mechanism by which it mediates the phosphatidylinositol 3-kinase (PI3K)/Akt pathway. Human kidney tubular epithelial cells (HKCs) were treated with TGF-β1 or curcumin alone, or TGF-β1 in combination with curcumin. The effect of curcumin on cell proliferation was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Expression of E-cadherin, cytokeratin, vimentin, alpha smooth muscle actin (α-SMA), fibroblast-specific protein 1 (FSP1) and key proteins of Akt/mammalian target of rapamycin (mTOR) pathway were analyzed by immunocytochemistry, real-time PCR and Western blot. Low dose curcumin (3.125 and 25 µmol/L) effectively promoted HKC proliferation. When HKCs were co-incubated with TGF-β1 and curcumin for 72 h, curcumin maintained the epithelial morphology in a dose-dependent manner, decreased expression of vimentin, α-SMA and FSP1 normally induced by TGF-β1, and increased expression of E-cadherin, cytokeratin. Importantly, we found that curcumin reduced Akt, mTOR and P70S6K phosphorylation, effectively suppressing the activity of the Akt/mTOR pathway in HKCs. Curcumin also promoted HKC proliferation, and antagonized TGF-β1-driven EMT through the inhibition of Akt/mTOR pathway activity, which may suggest an alternative therapy for renal fibrosis.
