Modified Atmosphere Packaging and 1-Methylcyclopropene Treatments Maintain the Fruit Quality of 'Wonmi' Persimmons during Export Simulation.

Persimmons are one of the most important export fruits in South Korea, where several tons are exported across the globe each year. In this study, the quality attributes of 'Wonmi' persimmon fruits were evaluated during an export simulation at 0 °C, 10 °C, and 24 °C with a combination of 1-Methylcyclopropene (1-MCP) and modified atmosphere packaging (MAP) treatments. The relative humidity during the export simulation was greater at room temperature (75-92%) and 0 °C (85% to 93%) than at 10 °C (42% to 60%).

Field Application of a Vis/NIR Hyperspectral Imaging System for Nondestructive Evaluation of Physicochemical Properties in 'Madoka' Peaches.

Extensive research has been performed on the in-field nondestructive evaluation (NDE) of the physicochemical properties of 'Madoka' peaches, such as chromaticity (a*), soluble solids content (SSC), firmness, and titratable acidity (TA) content. To accomplish this, a snapshot-based hyperspectral imaging (HSI) approach for filed application was conducted in the visible and near-infrared (Vis/NIR) region. The hyperspectral images of 'Madoka' samples were captured and combined with commercial HSI analysis software, and then the physicochemical properties of the 'Madoka' samples were predicted.

Preharvest Application of Chitosan Improves the Postharvest Life of 'Garmrok' Kiwifruit through the Modulation of Genes Related to Ethylene Biosynthesis, Cell Wall Modification, and Lignin Metabolism.

The influence of the preharvest application of chitosan on physicochemical properties and changes in gene expression of 'Garmrok' kiwifruit during postharvest cold storage (0 °C; RH 90-95%; 90 days) was investigated. Preharvest treatment of chitosan increased the fruit weight but had no significant effect on fruit size. The chitosan treatment suppressed the ethylene production and respiration rate of kiwifruit during the cold storage.

Potential role of pectate lyase and Ca(2+) in the increase in strawberry fruit firmness induced by short-term treatment with high-pressure CO2.

Postharvest treatment with high-pressure CO2 helps to control decay and increase firmness in strawberries. Increases in firmness occurred through modification of calcium binding to cell wall. However, the mechanism(s) involved in Ca(2+) migration to pectic polymers and other physiological events associated with the maintenance of increased firmness are not clearly understood.

Fruit quality, anthocyanin and total phenolic contents, and antioxidant activities of 45 blueberry cultivars grown in Suwon, Korea.

Blueberry fruits from 45 commercial cultivars (39 northern highbush and 6 half highbush blueberry) grown in Suwon, Korea were analyzed for fruit size, soluble solids content, titratable acidity, total anthocyanin content, total phenolic content, and antioxidant activity. Fruit characteristics varied widely among the 45 blueberry cultivars. Fruit weight ranged from 0.

Pulmonary venous malformation in a 4-year-old boy: a case report.

We report a case of a pulmonary venous malformation in a 4-year-old boy who presented with recurrent pneumonia. A radiograph revealed a right infrahilar mass and a hyperlucent right lung. Computed tomography (CT) demonstrated a mass containing intensely enhancing areas and multiple phleboliths located in the right lower lobe and encasing the right bronchus and right inferior pulmonary vein.

Impaired induction of cystatin S gene expression by isoproterenol in the submandibular gland of hypophysectomized rats.

Cystatin S, an inhibitor of cysteine proteases, is produced and secreted by acinar cells of the rat submandibular gland. Expression of the cystatin S gene is known to be induced at high levels by the beta-adrenergic agonist isoproterenol. In the present study, we revealed that in the submandibular gland of hypophysectomized adult male rats, the levels of induced cystatin S mRNA 24 h after a single administration of isoproterenol are strikingly lower than those in the gland of normal rats.

Expression of the fragile histidine triad gene in normal rat tissues and human kidney cancer cell lines.

The fragile histidine triad (FHIT) gene located in human chromosome 3p14.2 is a candidate tumor suppressor gene that has a diadenosine triphosphate (Ap3A) hydrolase activity, but its role in carcinogenesis remains uncertain. To investigate the role of FHIT in normal cells, specific polyclonal antibodies to recombinant rat FHIT protein were generated.
