Nomenclatural and systematic changes in the Neotropical caddisflies (Insecta: Trichoptera) [PDF]

open access: yes, 1999
Recent work on a catalog of the Neotropical caddisflies has resulted in the recognition of the need to make numerous lectotype designations, new names for homonyms, specific and generic synonymies, transfers of species between genera and genera between ...

Probiotic consumption reduces alveolar bone loss and kidney damage in pregnant rats with experimental periodontitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Bifidobacterium animalis subsp. lactis HN019 (B. lactis HN019) is a probiotic bacterial strain with immunomodulatory properties. Its benefits have been observed in healthy and systemically compromised animals with periodontitis (PD). Our objective was to investigate the local and systemic effects of the systemic administration of B.

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Clarifying nomenclatural uncertainties in Jupunba (Caesalpinioideae, Leguminosae)

open access: yesNordic Journal of Botany, EarlyView.
Molecular phylogenetic studies have prompted substantial revisions in the systematics of the former genus Abarema, resulting in the reinstatement of the genera Punjuba and Jupunba, and a re‐circumscription of Abarema. Despite these advances, some taxa still require nomenclatural adjustments to reflect monophyletic lineages.

Scanning-electron-microscopy observations and mechanical characteristics of ion-beam-sputtered surgical implant alloys [PDF]

open access: yes
An electron bombardment ion thruster was used as an ion source to sputter the surfaces of orthopedic prosthetic metals. Scanning electron microscopy photomicrographs were made of each ion beam textured surface.

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

open access: yesNordic Journal of Botany, EarlyView.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a
