OBJECTIVES: To investigate the gingival crevicular fluid (GCF) levels of interleukin (IL)-8 and IL-1α in gingivitis periodontitis sites same participant, as well their correlation with periodontal pocket depth (PPD) bleeding on probing (BOP). METHODS: This cross-sectional study was conducted at School Dental Sciences, Universiti Sains Malaysia, from April 2019 to December 2021. GCF samples were...

A tight-binding based bond-order potential (BOP) has been constructed for the fcc transition metal iridium that includes explicitly only d orbitals in the evaluation of the total energy. We show that hybridization between the nearly free electron sp band and the unsaturated covalently bonded d orbitals is important in determining the relative stabilities of the close-packed structures and that ...

In this report, a 5 kW PEFC system running on dry hydrogen with an appropriately sized Balance of Plant (BoP) was used to conduct experimental studies and analyses gas supply subsystems. The improper rating use BoP components has been found increase parasitic loads, which consequently direct effect the polymer electrolyte fuel cell (PEFC) efficiency. Therefore, minimisation loads while maintain...

The effects of changes in pH on the binding of agonists and antagonists to the human platelet thromboxane A2/prostaglandin H2 (TXA2/PGH2) receptor were determined. Competition binding studies were performed with the TXA2/PGH2 mimetic [1S-1 alpha,2 beta (5Z), 3 alpha(1E,3R*),4 alpha)]-7-[3-(3-hydroxy-4'-iodophenoxy)-1-buteny) 7-oxabicyclo-[2.2.1]-heptan-2-yl]-5-heptenoic acid ([125I]BOP). The pH...

Recently, we have shown that dexamethasone treatment of rabbits specifically reduces vascular smooth muscle responsiveness to agonists that interact with the vascular thromboxane A2 / prostaglandin H2 (TXA2 / PGH2) receptor. One potential site at which dexamethasone can influence prostanoid-mediated vasoconstriction may be at the level of the vascular TXA2 IPGH2 receptor. Therefore, we characte...

In this paper, I identify the bottom of the pyramid (BOP) markets as a new source of radical innovation. By focusing managerial attention on creating awareness, access, affordability, and availability (4As), managers can create an exciting environment for innovation. I suggest that external constraints can be utilized to build an innovation sandbox within which new products and business models ...

BACKGROUND Gingivitis is a common oral health problem. Untreated gingivitis may progress to periodontitis, a common cause of tooth loss. The prevalence of gingivitis and calculus among Puerto Rican children is unknown. Understanding this prevalence can support early public health preventative strategies. This study aims to estimate the prevalence of gingivitis and calculus among 12-year-old Pue...

BACKGROUND/AIM Despite significant advances in current medicine and improvement of overall health education, chronic periodontitis is still a widespread disease. Losing teeth is the most serious complication of this particular illness. The aim of this study was to examine patients with chronic periodontitis in order to evaluate the efficacy of non-surgical therapy and combination of amoxicillin...
