Saccharosydne is the most diverse genus of the tribe Saccharosydnini. Male, female and nymphal Saccharosydne have been captured in recent collections from garlic (Allium sativum), rye (Secale cereale) and pampas grass (Cortaderia spp.) in Argentina. In this contribution, we describe and illustrate a new species S. subandina sp. nov., adding information on the geographical distribution and host ...

Seeds collected at different maturation stages vary in physiological quality and patterns of protective antioxidant systems against deterioration. In this study we investigated the expression of genes that codify catalase (CAT), dismutase superoxide (SOD), and polyphenol oxidase (PPO) during the pre- and post-physiological maturation phases in whole seeds and in endosperms and embryos extracted...

The iridescent metallic green beetle, Chrysina gloriosa, which selectively reflects left circularly polarized light, possesses an exoskeleton decorated by hexagonal cells (approximately 10 microm) that coexist with pentagons and heptagons. The fraction of hexagons decreases with an increase in curvature. In bright field microscopy, each cell contains a bright yellow core, placed in a greenish c...

The term ‘‘amyloidosis’’ encompasses various clinical entities of unknown aetiology, characterised by extracellular deposit of amyloid (acellular protein material that presents yellowish-green birefringence under polarised light after Congo red staining). Clinical signs and symptoms depend on the anatomic distribution and intensity of the amyloid deposit. There are 2 main forms: systemic and lo...

Photoplethysmography is a simple measurement of the variation in blood volume in tissue. It detects the pulse signal of heart beat as well as the low frequency signal of vasoconstriction and vasodilation. The transmission type measurement is limited to only a few specific positions for example the index finger that have a short path length for light. The reflectance type measurement can be conv...

<em>Kepahiang Robusta coffee has received a Geographical Indication (GI) certificate. Maintaining the quality of green bean been achieved through application proper harvesting technology. This study aimed to evaluate effect fruit maturity level when harvested on yield losses due berry borer (CBB) and bean. The research was conducted from December 2019 August 2020 in Bukit Sari Village, Ka...

Clinanthus milagroanthus S. Leiva & Meerow, sp. nov. is described from the Department of La Libertad in Peru. The new species is most closely related to Clinanthus mirabilis (Ravenna) Meerow, with further affinities to Clinanthus viridiflorus (R. & P.) Meerow. It can be distinguished from Clinanthus mirabilis by its wider leaves, the much more brightly colored and wide spreading limb, and the m...

Colliod milium is a degenerative change, which is characterized clinically by development of multiple yellowish, translucent papules and nodules on the light exposed skin and histologically by the presence of colloid in the dermal papillae. This is a rare condition and has some variants. We report a case of colloid millium with nodular and plaque lesions on his ears. Our patient was a far...
