Polydopamine (PDA) generated by the oxidative self-polymerization of dopamine shows great potential for surface modification. Observed PDA nanostructures are nanoparticles and thin films. The formation mechanism of PDA is still unclear; thus, the manipulation of PDA nanostructures is a big challenge. In this study, we first demonstrated that folic acid shows a dramatic effect on the PDA nanostr...

OBJECTIVES This study was performed to determine the frequency of patent ductus arteriosus (PDA) reopening and the factors that may predict reopening after successful coil occlusion. BACKGROUND Transcatheter coil occlusion is a widely used and accepted method to close a PDA. After documented successful coil occlusion, we found PDAs that reopened. We hypothesized that specific factors are invo...

the abilities of aspergillus niger and serpula himantioides to immobilize lead (pb) from lead sulphide (pbs) were investigated. upon growth on potato dextrose agar (pda) amended with pbs which contained 10mm pb, no visible solubilization activity was detected. a. niger produced biomass in greater quantity compared to s. himantiodes in both experimental and control media. with a ratio of 1.13, a...

Patent ductus arteriosus (PDA) is highly prevalent in pre-term neonates (PTN) and has been recognized as a neonatal co-morbidity. The purpose of this study was to determine if levels of brain (or B-type) natriuretic peptide (BNP), a peptide secreted by ventricular myocytes in response to volume or pressure overload, correlate with the size of the PDA. In a prospective design, 52 PTN (no PDA: n=...

This survey study was undertaken to find out the prevalence and distribution of fungi occupying residential surfaces in Azadi Teaching Hospital Hevi Paediatric Duhok province, Iraq. Three hundred samples were collected from randomly selected areas laboratories, wards, consultation rooms, operating theatres hospital kitchen by swabs. These cultured on two selective fungal media (PDA SDA) also ai...

Sénizergues has proved that language equivalence is decidable for disjoint -deterministic PDA. Stirling has showed that strong bisimilarity is decidable for PDA. On the negative side Srba demonstrated that the weak bisimilarity is undecidable for normed PDA. Later Jančar and Srba established the undecidability of the weak bisimilarity for disjoint -pushing PDA and disjoint -popping PDA. In the ...

Electrical therapy has attracted significant attention because it can modulate cell behaviors and accelerate tissue repair. However, the effectiveness of electrical therapy is limited. This work develops electroresponsive and conductive polydopaminepolypyrrole microcapsules (PDA-PPy-MCs) on titanium surfaces using electrochemical deposition. During the electrochemical process, PDA and dexametha...

BACKGROUND In clinical and research practice linked to prostate cancer treatment, frequent monitoring of patient health-related quality of life (HRQOL) is essential. Practical and analytic limitations of paper questionnaire data capture may be overcome with the use of self-administered personal digital assistant (PDA) data collection. The objective of this study was to assess the reliability, v...
