Global warming is predicted to reduce the yield of rice, which feeds more than half of the world’s population. A rise in temperature will inevitably hamper rice production by causing drought and flooding. Melatonin has the capacity to ameliorate such adverse effects. Here, we propose multiple genetic means of producing melatonin-enriched, high-yield rice variants to adapt upcoming global warming.

BACKGROUND: For global water shortage concerns and high cost of mineral nutrients it is necessary to decrease the amount of nutrient solutions in greenhouse production systems. Deficit fertigation may negatively affect the crop productivity and phytohormones can mitigate the adverse effects of stresses. OBJECTIVE: We studied the effects of deficit fertigation in combination with salicylic acid (SA) and putrescine (PUT) on strawberry fruit yield and quality. METHODS: Strawberry plants were fertilized with a complete nutrient solution of 220 (control), 180 (mild deficit fertigation) and/or 140 mL/dD (severe deficit fertigation), and treated with PUT (at 0 and 2 mM) and/or SA (at 0 and 2 mM) and the combinations of these treatments during growth stages. Fruit growth, quality parameters, yield and phytochemical compounds were evaluated at harvest. RESULTS: Mild deficit fertigation (MDF) (140 mL/d) significantly enhanced the yield and quality of the fruit, and both PUT and SA, enhanced the positive effects of MDF on crop productivity. SA and PUT decreased the negative effects of DF on crop yield and fruit growth. CONCLUSIONS: The results of this study indicate that it is possible to substantially enhance the quality and productivity of strawberries with a MDF regime, and PUT and SA treatments.

The application of electron energy loss spectroscopy (EELS) to light element analysis is rapidly becoming an important aspect of the microcharacterization of solids in materials science, however relatively stringent requirements exist on the specimen thickness under which one can obtain EELS data due to the adverse effects of multiple inelastic scattering.1,2 This study was initiated to determine the limitations on quantitative analysis of EELS data due to specimen thickness.

Zusammenfassung. Zielsetzung: Übersicht über Suchtpotenzial und andere Risiken von Opioidanalgetika im höheren Lebensalter. Methodik: Narrativ review. Literaturrecherche in PubMed (Suchbegriffe: opioid analgesics UND abuse; opioid analgesics UND dependence; opioid analgesics UND addiction; opioid analgesics UND adverse effects; jeweils UND elderly) sowie aktuellen einschlägigen Standardwerken; Auswahl nach altersmedizinischer Relevanz und Aktualität. Ergebnisse: Die Verordnung von Opioidanalgetika (OA) hat in den letzten 25 Jahren massiv zugenommen, die weitaus meisten Verordnungen entfallen auf alte Menschen und Menschen mit chronischen Nicht-Tumorschmerzen (CNTS). Die diagnostischen Kriterien für die Opiatabhängigkeit in ICD-10 und DSM-5 sind für die OA-Behandlung von CNTS ungeeignet. Bei langfristiger OA-Behandlung bei CNTS kann eine spezifische Form von Abhängigkeit entstehen, die nicht mit der illegalen Opiat-(Heroin-)Sucht gleichzusetzen ist. Vorbestehende Suchterkrankungen und andere psychische Störungen sind die wesentlichsten Risikofaktoren. Weitere Nebenwirkungen sind zu beachten. Schmerztherapie bei Suchtkranken stellt eine besondere Herausforderung dar. Schlussfolgerungen: Die Anwendung von OA bei CNTS verlangt eine sorgfältige Indikationsstellung. Die besondere Form der Abhängigkeit von OA ist nicht ausreichend erforscht und wird zu wenig beachtet.

Abstract. Pulse volume (PV) and its related measures, such as modified normalized pulse volume (mNPV), direct-current component (DC), and pulse rate (PR), derived from the finger-photoplethysmogram (FPPG), are useful psychophysiological measures. Although considerable uncertainties exist in finger-photoplethysmography, little is known about the extent of the adverse effects on the measures. In this study, we therefore examined the inter-method reliability of each index across sensor positions and light intensities, which are major disturbance factors of FPPG. From the tips of the index fingers of 12 participants in a resting state, three simultaneous FPPGs having overlapping optical paths were recorded, with their light intensity being changed in three steps. The analysis revealed that the minimum values of three coefficients of Cronbach’s α for ln PV, ln mNPV, ln DC, and PR across positions were .948, .850, .922, and 1.000, respectively, and that those across intensities were .774, .985, .485, and .998, respectively. These findings suggest that ln mNPV and PR can be used for psychophysiological studies irrespective of minor differences in sensor attachment positions and light source intensity, whereas and ln DC can also be used for such studies but under the condition of light intensity being fixed.
