Polydiacetylene (PDA) compound has unique chromatic properties when embedded in methylcellulose base. Therefore, this could be used as intelligent packaging. PDA exhibits blue-to-red color transition under certain stimuli, which was caused by alterations in PDA conjugation length backbone. For a specific color modification, bio-recognition tools were covalently linked with PDA. In this work, a ...

In the preceding article, we investigated the spatial properties of the induction of the prolonged depolarizing afterpotential (PDA) by shifting visual pigment from the rhodopsin (R) to the metarhodopsin (M) state in the barnacle photoreceptor. In this work, we have studied the ranges within the cell of the antagonistic effects on the PDA of M-to-R transfer. When this transfer occurs during a P...

BACKGROUND AND OBJECTIVES This study's objective was to evaluate the acceptability, effect, and use of handheld computers (also known as personal digital assistants or PDAs) as a reward for undergraduate rural community-based family medicine preceptors. METHODS All rural, undergraduate family physician teachers who accepted an undergraduate student for a 1-month placement were offered the cho...

A PDA is used mainly for downloading data from a stationary server such as a desktop PC in an infrastructure network based on wireless LAN. Thus, the overall performance depends heavily on the performance of such downloading with PDA. Unfortunately, for a PDA the time taken to receive data from a PC is longer than the time taken to send it by 53%. Thus, we measured and analyzed all possible fac...

In this paper, the issue of designing an iterative detection and decoding (IDD) aided receiver relying on the lowcomplexity probabilistic data association (PDA) method, is addressed for turbo-coded multiple-input–multiple-output (MIMO) systems using general M -ary modulations. We demonstrate that the classic candidate-search aided bit-based extrinsic loglikelihood ratio (LLR) calculation method...

BACKGROUND/AIMS Mussel-inspired polydopamine (PDA) is known to be an effective bioadhesive and bioactive material for controlling stem cell fate, which is important in stem cell-based regenerative medicine; however, the effect of PDA on osteogenic differentiation of periodontal ligament stem cells (PDLSCs) is not fully understood. In this study, we investigated the osteoinductive effect of PDA ...

AIM Patent Ductus Arteriosus is an important cause of morbidity and mortality in preterms. As birth weight decrease, risks increase. Main aim of our study is to emphasize the effectiveness and safety of percutaneous PDA closure even in extremely low birth infants. MATERIALS AND METHODS In our center between the dates June 2014-June 2016, PDA of 10 patients less than 1,000 gr were closed percu...

BACKGROUND Closure of PDA can be associated with echocardiographic changes including deterioration of LV systolic function. Although PDA is commonly encountered in dogs, few comprehensive reports of echocardiographic changes in dogs with PDA closure are available. OBJECTIVES To evaluate the short-term echocardiographic changes observed after PDA closure in dogs using strain analysis. ANIMAL...

Patent ductus arteriosus (PDA) is a common congenital heart defect. All PDAs, regardless of size or degree of symptoms, require occlusion. Transcatheter PDA occlusion features fewer complications than trans-thoracic closure. It is also more cost-effective and has an excellent occlusion rate. Therefore, transcatheter PDA occlusion is accepted as the standard treatment option for PDA. However, tu...

A facile, versatile, and one-pot sonochemical synthesis of polydopamine (PDA)-nanocapsules from dopamine is reported. The nanocapsules (227 ± 25 nm) can encapsulate hydrophobic substances while retaining the reactivity of PDA toward nucleophilic reactions, enabling facile surface modification for different applications. PDA nanocapsules are nontoxic to mammalian cells while Cu-containing PDA ca...
