The objective of this study is to investigate the effects of irradiation from light-emitting diodes (LEDs) on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitted from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total flavonoids and several pigments were investigated, along with the antioxidant potential. The colour parameters (L*, a* and b*) and firmness of the fruit were also determined...

Nitric oxide (NO) and polyamines (PAs) belong to plant growth and development regulators. These compounds play a key role in numerous physiological processes e.g. seed germination. Based on the suggestion of overlapping of NO and PAs biosynthetic pathways, we demonstrated a cross-talk of NO and PAs in regulation of embryonic dormancy release. The aim of the work was to investigate an impact of PAs (Put, Spd and Spm) or NO short-term fumigation on nitrite, urea, Arg and ornithine (Orn) content, NO synthase-like (NOS-like) and arginase activity in axes of apple (Malus domestica Borkh...

An international standard (ISO: 23317:2014) exists for the in vitro testing of inorganic biomaterials in simulated body fluid (SBF). This standard uses TRIS buffer to maintain neutral pH in SBF, but in our previous paper, we showed that the interaction of a tested glass-ceramic material with TRIS can produce false-positive results. In this study, we evaluated whether the HEPES buffer, which also belongs to the group of Good's buffers, would be more suitable for SBF. We compared its suitability in two media: SBF with HEPES and demineralized water with HEPES...

Mati Kahru, Zhongping Lee, B Greg Mitchell, Cynthia D Nevison
The influence of decreasing Arctic sea ice on net primary production (NPP) in the Arctic Ocean has been considered in multiple publications but is not well constrained owing to the potentially large errors in satellite algorithms. In particular, the Arctic Ocean is rich in coloured dissolved organic matter (CDOM) that interferes in the detection of chlorophyll a concentration of the standard algorithm, which is the primary input to NPP models. We used the quasi-analytic algorithm (Lee et al 2002 Appl. Opti...

Integra(®) matrix wound dressing (MWD) is used for the reconstruction of full-thickness skin defects. For the treatment of complex wounds, this dermal substitute is available as a flowable wound matrix (FWM) of identical composition. To clarify whether variations in sample preparation and consistency affect the biocompatibility and tissue incorporation, we herein compared MWD and FWM. The matrices were characterized using scanning electron microscopy and histology. Moreover, they were implanted in mouse dorsal skinfold chambers to analyze their in vivo performance over 2 weeks...

BACKGROUND: Rapid rule-out strategies using high-sensitivity cardiac troponin assays are largely supported by studies performed outside the US in selected cohorts of patients with chest pain that are atypical of US practice, and focused exclusively on ruling out acute myocardial infarction (AMI), rather than acute myocardial injury, which is more common and associated with a poor prognosis. METHODS: Prospective, observational study of consecutive patients presenting to emergency departments [derivation (n = 1647) and validation (n = 2198) cohorts], where high-sensitivity cardiac troponin I (hs-cTnI) was measured on clinical indication...

Renal proximal tubule cells (RPTCs) are responsible for glomerular filtration and maintenance of water/electrolyte balance. To regenerate a proximal tubule, sufficient cell numbers and normal cell function are requisite. Collagen has been routinely used as a substrate for culturing human RPTCs (HRPTCs); however, the role of biomaterials has not been thoroughly explored. In this study, RPTCs retrieved from human nephrectomy/nephroureterectomy specimens were cultivated on chitosan as a substrate in serum-free condition for up to 150 days...

'Fuji' is one of the most popular and highly-produced apple cultivars worldwide, and has been frequently used in breeding programs. The development of genotypic markers for the preferable phenotypes of 'Fuji' is required. Here, we aimed to define the haplotypes of 'Fuji' and find associations between haplotypes and phenotypes of five traits (harvest day, fruit weight, acidity, degree of watercore, and flesh mealiness) by using 115 accessions related to 'Fuji'. Through the re-sequencing of 'Fuji' genome, total of 2,820,759 variants, including single nucleotide polymorphisms (SNPs) and insertions or deletions (indels) were detected between 'Fuji' and 'Golden Delicious' reference genome...

This study examined the effect of debagging time on color and flavor / taste compounds in the non-red apple cultivar 'Golden Delicious' and red cultivar 'Qinguan' at mid and late stages of fruit development. Debagging briefly improved the red color in both cultivars, the peel of 'Golden Delicious' presenting pale-pink hue. However, rapid anthocyanin accumulation occurred in apple peel at a specific time (after 179 days after flowering (DAF) in 'Qinguan') and was unaltered by debagging time in the red cultivar 'Qinguan'...

It has been suggested that unoprostone isopropyl (UNO) has potent neuroprotective activity in the retina. The effect of sustained transscleral UNO delivery to the posterior segment of the eye on photoreceptor degeneration was evaluated. UNO was loaded into a device made of poly(ethyleneglycol) dimethacrylate by polydimethylsiloxane mold-based UV-curing. The amount of UNO diffusing from these devices was measured using high-performance liquid chromatography. The polymeric devices that released UNO at 1.8 μg/day were implanted on the sclerae of S334ter rats at postnatal 21 days, and electroretinograms (ERGs) were compared with those of topical application and placebo devices...

Amidst a struggling economy, organizations are ruled by the survival of the fittest paradigm but it is the employees who tend to pay the price, with increased demands which, oftentimes, fall outside their job scope. In the present paper, we examined whether pressuring people to engage in such organizational citizenship behaviors (OCB) might in fact backfire and lead to increased Counterproductive Work Behavior (CWB) because of compensatory mechanisms. We propose a typology of OCB that distinguishes between discretionary and elicited OCB, hypothesizing that elicited but not discretionary OCB, positively relates to CWB...

We studied the ability of collagen vitrigel material to repair cartilage in vivo when used alone or with transforming growth factor-β (TGF-β). We measured the time course and quantity of TGF-β1 released from the collagen vitrigel in vitro to quantify the controlled release of TGF-β1. Over 14 days, 0.91 ng of TGF-β was released from the collagen vitrigel. Osteochondral defects were made in the femoral trochlear groove in 36 Japanese white rabbits, which were divided into three groups: untreated group (group A), collagen vitrigel-implanted group (group B), and TGF-β1-incorporated collagen vitrigel-implanted group (group C)...

Apple orchard management practices may affect development and phenology of arthropod pests, such as the codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), which is a serious internal fruit-feeding pest of apples worldwide. Estimating population dynamics and accurately predicting the timing of CM development and phenology events (for instance, adult flight, and egg-hatch) allows growers to understand and control local populations of CM. Studies were conducted to compare the CM flight phenology in commercial and abandoned apple orchard ecosystems using a logistic function model based on degree-days accumulation...
