Large and non-spherical seeds are less likely to form a persistent soil seed bank.

There is some evidence that seed traits can affect the long-term persistence of seeds in the soil. However, findings on this topic have differed between systems. Here, we brought together a worldwide database of seed persistence data for 1474 species to test the generality of seed mass-shape-persistence relationships.

Similar functional roles of the Orexin-1 and Orexin-2 receptors within the dentate gyrus area of the hippocampus in the stress-induced antinociceptive responses in the acute pain model in the rat.

Studies establish that the brain's Orexin system is involved in pain modulation. Orexin-1 and orexin-2 receptors (OX1 and OX2r, respectively) are essential in responsiveness to stressful stimuli. Some evidence indicates that the hippocampus's dentate gyrus (DG) potentially modulates pain and stress.

MASTREE+: Time-series of plant reproductive effort from six continents.

Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series data from across the globe and makes these data freely available to the community.

A Review of Dental Composites: Methods of Characterizations.

Dental composites are becoming increasingly popular in esthetic restorative dentistry and present a promising substitute for amalgam. However, the major hurdles that hinder their total adoption in restorative dentistry are limited longevity and possible health risks, leading to significant attempts for addressing these shortcomings. Besides the new materials, the evaluation methods play a critical role in the introduction and improvement of these types of materials.

First Report of Northern Root-Knot Nematode, Meloidogyne hapla, Parasitic on Oaks, Quercus brantii and Q. infectoria in Iran.

Root-knot nematodes (RKN) are the most serious plant parasitic nematodes having a broad host range exceeding 2,000 plant species. Quercus brantii Lindl. and Q.
