Nitrogen forms influence microcystin concentration and composition via changes in cyanobacterial community structure. [PDF]

PLoS ONE, 2014
The eutrophication of freshwaters is a global health concern as lakes with excess nutrients are often subject to toxic cyanobacterial blooms. Although phosphorus is considered the main element regulating cyanobacterial biomass, nitrogen (N) concentration

A new genus of the millipede tribe Brachyiulini (Diplopoda: Julida: Julidae) from the Aegean region [PDF]

, 2013
A new genus of the julid tribe Brachyiulini, Enghophyllum gen. nov., is described, comprising two species from Greece. The type-species, E. naxium (Verhoeff, 1901) comb. nov. (ex Megaphyllum Verhoeff, 1894), appears to be rather widespread in the Aegean:

Congener Patterns of Persistent Organic Pollutants Establish the Extent of Contaminant Biotransport by Pacific Salmon in the Great Lakes.

Environmental Science and Technology, 2016
In the Great Lakes, introduced Pacific salmon (Oncorhynchus spp.) can transport persistent organic pollutants (POPs), such as polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), to new environments during their spawning ...

Synthesis of cis-thiiranes as diastereoselective access to epoxide congeners via 4π-electrocyclization of thiocarbonyl ylides

Nature Communications, 2022
Thiirane, the sulfur congener of oxirane, has been hard to access in a stereodefined form. Here, the authors accomplished a highly stereoselective synthesis of cis-diarylthiiranes through the stereospecific sulfurization of E,E-aldazine N-oxides.

Inhalation and Dietary Exposure to PCBs in Urban and Rural Cohorts via Congener-Specific Measurements

Environmental Science and Technology, 2014
Polychlorinated biphenyls (PCBs) are a group of 209 persistent organic pollutants, whose documented carcinogenic, neurological, and respiratory toxicities are expansive and growing. However, PCB inhalation exposure assessments have been lacking for North

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about
