Effects of DL-palmitoylcarnitine (PC), an inhibitor of calciumactivated, phospholipid-dependent protein kinase (protein kinase C), on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced cell differentiation were investigated in human promyelocytic leukemia cells (HL-60). TPA caused HL-60 cell adhesion concomitant with morphological changes, and an increase in acid phosphatase activity. The media...

E. faecalis in endodontic infection represents a biofilm type of disease, which explains the bacteria's resistance to various antimicrobial compounds and the subsequent failure after endodontic treatment. The purpose of this study was to compare antimicrobial activities and bacteria kinetic adhesion in vitro for three endodontic medicaments with a clinical isolate of E. faecalis. We devised a s...

  Objective: Adhesion of Lactobacillus acidophilus (L. acidophilus) to dental porcelain surface may lead to gingival inflammation and secondary caries. Surface roughness is among the factors affecting this adhesion. The purpose of this study was to evaluate the effects of four different surface treatment methods on adhesion of L. acidophilus to dental porcelain.   Methods: Sixty specimens (3x10...

This study analysed the impact of turning rate, centre mass height, and road adhesion coefficient on rollover stability heavy-duty automated guided vehicles (AGVs) using a multi-body dynamics simulation model. The lateral deflection angle was used as metric to evaluate behaviour AGVs, results were obtained quantitatively. findings showed that rate had largest AGV stability, followed by while le...

Clogging occurs during mechanical tunneling with a Tunnel Boring Machine (TBM) because of adhesion of clayey soils to the cutterhead and conveyor system. The present study examined the effects of water and sand contents on clogging in Montmorillonite clayeysoil. Testing was carried out using an adhesion test device on 28 samples with different water and sand contents to determine adhesionstress...

the objective of this study was to determine the effectiveness of topical administration of honey in prevention of or reduction in post-surgical peritoneal adhesions in dog. the study was conducted on 18 adultfemale mixed-breed dogs with a mean ± sd weight of 20 ± 4.25 kg. a standardized surgical trauma (serosaltrauma model) was made in the dogs’ descending colon to induce adhesion formation. t...

background: the aim of this study is to investigate the effect of vitamin a and c, as the agents that improve wound healing, on the adhesion formation process. materials and methods: sixty male wistar rats were used. they underwent midline laparotomy, for repair of a peritoneal injury, and were then assigned to four groups. group 1 (vitamin a) received 2000 units/kg intramuscular injection of v...

Abstract Nanoindentation was performed on Ti-B-Si-C and SiCN films deposited Si substrates at varying loads depths of penetrations. The intensity chipping got enhanced with an increasing load which represented geometrically. pop-in pop-out events occurring in the unloading were explained as cracking high-pressure phase transformation. interfacial fracture stability adhesion film-substrate syste...
