Abstract
High risk of acute morbidities and even mortality from expanding the antibiotics resistant infectious wounds force indefinite efforts for development of high performance wound-healing materials. Herein, we design a procedure to fabricate a hyaluronic acid (HA)-based hydrogel to conjugate curcumin (Gel-H.P.Cur). The highlight of this work is to provide a favorite condition for capturing curcumin while protecting its structure and intensifying its activities because of the synchronization with HA. Accordingly, HA as a major component of dermis with a critical role in establishing skin health, could fortify the wound healing property as well as antibacterial activity of the hydrogel. Gel-H.P.Cur showed antibacterial properties against Pseudomonas aeruginosa (P. aeruginosa), which were examined by bactericidal efficiency, disk diffusion, anti-biofilm, and pyocyanin production assays. The effects of Gel-H.P.Cur on the inhibition of quorum sensing (QS) regulatory genes that contribute to expanding bacteria in the injured place was also significant. In addition, Gel-H.P.Cur showed high potential to heal the cutaneous wounds on the mouse excisional wound model with repairing histopathological damages rapidly and without scar. Taken together, the results strongly support Gel-H.P.Cur as a multipotent biomaterial for medical applications regarding the treatment of chronic, infected, and dehiscent wounds.

Abstract
Hyaluronic acid (HA), as a safe biomaterial with minimal immunogenicity, is being employed in a broad range of medical applications. Since unmodified HA has a high potential for biodegradation in the physiological condition, herein, an HA-based cross-linked hydrogel was formulated using polydimethylsiloxane-diglycidyl ether terminated (PDMS-DG) via epoxide-OH reaction. The formation of HA-PDMS hydrogel was confirmed using FTIR, NMR, and FESEM. Temperature demonstrated a critical role in the physicochemical properties of the final products. Gel-37, which formed at 37 °C, had a higher modification degree (MD) and more stability against hyaluronidase and oxidative stress than the hydrogel formulated at 25 °C (Gel-25). In addition, the swelling ratio, roughness, and porous network topology of Gel-25 and Gel-37 were different. The rheology measurement indicated that HA-PDMS hydrogel had a stable viscoelastic character. The hydrogel was also biocompatible, non-cytotoxic, and considerably stable during 7-months storage. Overall, various determined parameters confirmed that HA-PDMS hydrogel is worth using in different medical applications. Keywords: Hyaluronic acid; Polydimethylsiloxane-diglycidyl ether terminated; Hydrogels; Long-term stability; Viscoelastic behavior; Biocompatibility.

Abstract
The current study is aimed at investigation of the opium effects on the apoptosis of different cell lines in culture medium and compares such effects with one another. The study is carried out on over 8 cell lines (AA8, AGS, Hela, HepG2, MCF7, N2a, PC12, WEHI). A 2.86 x 10-4 g/ml opium concentration was prepared and added to the culture medium of the cell lines for 48 hours. Cytotoxicity was tested by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. The apoptotic effect of opium on the cell lines was analyzed by Annexin-PI test. Opium with concentration of 2.86 x 10-4 g/ml in 48 hours significantly induces apoptosis in certain cell lines (i.e. AA8, N2a, WEHI), apoptosis and necrosis in some others (i.e. Hela, HepG2, MCF7, and PC12), and also solely necrosis in the AGS cell line. One could infer that the usage of opium with different levels in different tissues leads to certain disorders in some tissues and may have therapeutic effects under distinctive conditions (i.e. unchecked growth of cells) as confirmed by the results.

Abstract
To investigate the effect of BMP4 on cardiomyocyte differentiation of adipose tissue-derived stem cells (ADSCs), mouse ADSCs were treated with different concentrations of BMP4 in media containing fetal bovine serum (FBS) or Knockout™ Serum Replacement (KoSR). 3 weeks after cardiac induction, differentiated ADSCs expressed some cardiac-specific genes and proteins. BMP4 treatment upregulated the expression of cardiac transcription factors. In both FBS and KoSR-supplemented media, lower concentrations of BMP4 had a positive effect on the expression of MLC2A gene, while MLC2V was more expressed with higher concentrations of BMP4. BMP4 treatment in KoSR supplemented medium was more efficient for cardiac induction. Supplementation of culture media with insulin-transferrin-selenium improved the expression of MLC2A gene. The results of this study indicated that BMP4 is important for cardiac differentiation of the ADSCs. However, BMP4 was not enough for structural and functional maturation of the ADSC-derived cardiomyocytes.

Abstract
Evidence shows that probiotic bacteria can undergo substantial structural and morphological changes in response to environmental stresses, including antibiotics. Therefore, this study investigated the effects of penicillin G (0.015, 0.03, and 0.06 mg/l) on the morphology and adhesion of Lactobacillus acidophilus ATCC 4356, including the colony morphotype, biofilm production, hydrophobicity, H₂O₂ formation, S-layer structure, and slpA gene expression. Whereas only smooth colonies grew in the presence of penicillin, rough and smooth colony types were observed in the control group. L. acidophilus ATCC 4356 was found to be hydrophobic under normal conditions, yet its hydrophobicity decreased in the presence of the antibiotic. No biofilm was produced by the bacterium, despite testing a variety of different culture conditions; however, treatment with penicillin G (0.015-0.06 mg/l) significantly decreased its production of H₂O₂ formation and altered the S-layer protein structure and slpA gene expression. The S-protein expression decreased with 0.015 mg/l penicillin G, yet increased with 0.03 and 0.06 mg/l penicillin G. In addition, the slpA gene expression decreased in the presence of 0.015 mg/l of the antibiotic. In conclusion, penicillin G was able to alter the S-layer protein production, slpA gene expression, and certain physicochemical properties of Lactobacillus acidophilus ATCC 4356.

Abstract
BACKGROUND African Americans with hypertension are prone to target-organ damage and adverse cardiovascular events. Biomarkers for early detection of target-organ damage in this ethnic group are needed. Adrenomedullin (ADM) is a circulating vasoactive peptide with vasodilatory and antiproliferative effects that has been reported to be elevated in adults with hypertension. METHODS We investigated the associations of plasma levels of mid-regional pro-ADM (MR-proADM) with pulse pressure, left ventricular mass (LVM), and albuminuria in 1,034 African-American adults (65 +/- 9 years, 72% women) with hypertension. MR-proADM was measured by an immunoluminometric assay, LVM was assessed by 2-dimensional echocardiography, and albuminuria was assessed by urine albumin:creatinine ratio (UACR). Multivariable regression analyses were used to assess whether plasma MR-proADM was independently associated with pulse pressure, LVM indexed by height to the power 2.7 (LVMi), and UACR. RESULTS Plasma MR-proADM was significantly correlated (P < 0.001) with pulse pressure, LVMi, and UACR. In separate multivariable linear regression models that adjusted for age and sex, log MR-proADM was associated with greater pulse pressure (P = 0.007), log LVMi (P = 0.001), and log (UACR+1) (P < 0.0001). After additional adjustment for body mass index (BMI), total and high-density lipoprotein (HDL) cholesterol, smoking history, diabetes, estimated glomerular filtration rate (eGFR), history of myocardial infarction (MI) or stroke, and medication use, log MR-proADM remained significantly associated with greater pulse pressure (P = 0.001), log LVMi (P = 0.029), and log (UACR+1) (P = 0.002). CONCLUSIONS In African-American adults with hypertension, plasma MR-proADM is independently associated with pulse pressure, LVMi, and albuminuria and is a potential biomarker for target organ damage.

Abstract
BACKGROUND African Americans with hypertension have higher cardiovascular morbidity and mortality than hypertensives from other ethnic groups. Plasma D-dimer, a fragment generated from fibrin during lysis of mature clot in vivo, is a predictor of adverse cardiovascular events. OBJECTIVE We investigated whether plasma levels of D-dimer differ between African American (AA) and non-Hispanic white (NHW) adults with hypertension. METHODS Participants included 933 AA (65 +/- 9 years, 72% women) and 821 NHW (61 +/- 9 years, 56% women) from the community. D-dimer was measured using an immunoturbidimetric assay. Multivariable regression analyses, stratified by gender, were performed to assess whether AA ethnicity was associated with D-dimer levels after adjustment for age, body mass index (BMI), total and high-density lipoprotein (HDL) cholesterol, systolic blood pressure, diabetes, history of smoking, medication (statin and aspirin) use, lifestyle variables (physical activity, alcohol intake, and education), estimated glomerular filtration rate (eGFR), and a marker of inflammation, C-reactive protein (CRP). RESULTS D-dimer levels were higher in AA men and women than in their NHW counterparts (mean +/- SD; men 256 +/- 199 vs. 190 +/- 183 ng mL(-1), P < 0.001; women, 290 +/- 233 vs. 225 +/- 195 ng mL(-1), P < 0.001). In both sexes, after adjustment for age, conventional risk factors, medication use, and lifestyle variables, AA ethnicity remained associated with higher D-dimer levels (P = 0.002 in men, P = 0.006 in women). These associations remained significant after additional adjustment for eGFR and plasma CRP (P = 0.003 in men, P < 0.0001 in women). CONCLUSIONS Among adults with hypertension, AA ethnicity was independently associated with higher plasma levels of D-dimer.
