The toxic effects of citrinin in turkeys and ducklings was studied in four trials. Citrinin dissolved in dimethyl sulfoxide-70% ethanol solution (3:1, volume/volume) was administered by gavage to male turkey poults and male white Pekin ducklings. When seven-day-old ducklings were given doses of citrinin between 30 to 110 mg/kg body weight, most of the treated ducklings which died (49/80) did so within four to 12 hours. Blood samples were collected sequentially at 3, 6, 12, and 24 hours after administration from seven-day-old ducklings given the single lethal dose (LD50). The alterations included hyperkalemia (P less than or equal to 0.01) and metabolic acidosis characterized by reduced blood pH (P less than or equal to 0.01) and base excess (P less than or equal to 0.01). Fourteen-day-old turkeys and ducklings given 56 or 57 mg/kg, respectively, were killed at 1, 3, 6, 12, 24, 48, and 72 hours after treatment. The principal alteration in both species was nephrosis that was more severe in turkeys than in ducklings. Tubular necrosis was the dominant lesion at three to 72 hours in turkeys and at six to 24 hours in ducklings. Hepatic and lymphoid lesions occurred in both turkeys and ducklings treated with citrinin.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh Isoimmunization

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Enzyme Evolution

This feed focuses on molecular models of enzyme evolution and new approaches (such as adaptive laboratory evolution) to metabolic engineering of microorganisms. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pharmacology of Proteinopathies

This feed focuses on the pharmacology of proteinopathies - diseases in which proteins abnormally aggregate (i.e. Alzheimer’s, Parkinson’s, etc.). Discover the latest research in this field with this feed.

Alignment-free Sequence Analysis Tools

Alignment-free sequence analyses have been applied to problems ranging from whole-genome phylogeny to the classification of protein families, identification of horizontally transferred genes, and detection of recombined sequences. Here is the latest research.
