Effects of diesel exhaust particles on the health and survival of the buff-tailed bumblebee Bombus terrestris after acute and chronic oral exposure.

The diesel-powered transportation sector is a major producer of environmental pollution in the form of micro- and nanoscale diesel exhaust particles (DEP). Pollinators, such as wild bees, may inhale DEP or ingest it orally through plant nectar. However, if these insects are adversely affected by DEP is largely unknown.

Diesel exhaust particles alter gut microbiome and gene expression in the bumblebee .

Insect decline is a major threat to ecosystems around the world as they provide many important functions, such as pollination or pest control. Pollution is one of the main reasons for the decline, alongside changes in land use, global warming, and invasive species. While negative impacts of pesticides are well-studied, there is still a lack of knowledge about the effects of other anthropogenic pollutants, such as airborne particulate matter, on insects.

Primary and secondary angiosarcomas: a comparative single-center analysis.

Background: Angiosarcomas (AS) are rare vascular malignancies. They are subdivided into primary (PAS) and secondary angiosarcomas (SAS). The objective was to compare the characteristics of AS subtypes.

Uncomplicated postoperative course after transfusion of 176 units of blood products during a single cardiovascular surgery.

A patient with massive perioperative bleeding after repeat aortic surgery for proximal aortic redissection, anastomotic disruption, and prosthetic infection after recent surgery for acute type A aortic dissection was managed with, in total, 176 units of blood products during a 25-hour operating room session. The postoperative course was completely uneventful. Enduring and continuous hemostasis with mediastinal gauze packing, volume replacement, and timely blood product substitution may overcome temporary coagulopathy in desperate surgical circumstances.

Integration of microalgae systems at municipal wastewater treatment plants: implications for energy and emission balances.

Integrating microalgae systems (MAS) at municipal wastewater treatment plants (WWTPs) to produce of bioenergy offers many potential synergies. Improved energy balances provide a strong incentive for WWTPs to integrate MAS, but it is crucial that WWTPs maintain their barrier function to protect water resources. We perform a prospective analysis of energy and emission balances of a WWTP with integrated MAS, based on a substance flow analysis of the elements carbon (C), nitrogen (N), and phosphorus (P).
