Blood Parasites of Illinois Wild Turkeys [PDF]

, 1976
Blood smears, from 152 wild turkeys (Meleagris gallopavo silvestris) killed during hunting seasons in southern Illinois, were examined for blood parasites. Haemoproteus meleagridis infected 34% of the 83 adult and 19% of the 69 immature turkeys.

A Dual‐Membrane Biomimetic Nanoplatform Enables Triple‐Modal Therapy Against SARS‐CoV‐2 Through Viral Decoy, Inflammation Neutralizing, and Intracellular RNAi

Advanced Science, EarlyView.
[A&T]MLN is a triple‐modal nanoplatform with siRNA‐loaded LN coated with hybrid ACE2/macrophage membrane. It blocks viral entry, neutralizes IL‐6/IL‐1β/TNF‐α, and delivers siRNA to suppress viral replication. In a murine lung injury model, it attenuates inflammation, offering a multi‐pronged strategy against SARS‐CoV‐2 variants and hyperinflammation ...

Plasma carotenoid levels in passerines are related to infection by (some) parasites

Frontiers in Ecology and Evolution, 2014
Plumage coloration plays an important role in intra and inter-sexual competition in birds. Many of the yellow, orange or red colours present in birds are carotenoid dependent. Carotenoids can not be synthetized de novo by birds and consequently should be

Blood parasites of penguins: a critical review

Parasitology, 2016
SUMMARYBlood parasites are considered some of the most significant pathogens for the conservation of penguins, due to the considerable morbidity and mortality they have been shown to produce in captive and wild populations of these birds. Parasites known to occur in the blood of penguins include haemosporidian protozoans (Plasmodium, Leucocytozoon ...

cAMP-Signalling Regulates Gametocyte-Infected Erythrocyte Deformability Required for Malaria Parasite Transmission. [PDF]

, 2015
Blocking Plasmodium falciparum transmission to mosquitoes has been designated a strategic objective in the global agenda of malaria elimination. Transmission is ensured by gametocyte-infected erythrocytes (GIE) that sequester in the bone marrow and at ...

Intelligent Programmable Membrane Nanosponge for Early Virus Blocking

Advanced Science, EarlyView.
A smart programmable nanosponge (ACNPs) displays high‐density viral receptors on its membrane and encapsulates fusion inhibitors to capture virions at the infection source through competitive binding and blocks their entry through protease inhibition for ultra‐early cascade interception. This modular, mucus‐penetrating platform shifts antiviral defence
