A Complement Fixation Test for Dengue.

Experimental Biology and Medicine, 1948
Studies carried out by one of us (A. B. S.) since 1944 have established the fact that several immunologically distinct but related types of virus are responsible for the clinically typical and) atypical forms of dengue.1 Since the adaptation of dengue virus to mice,2 Sabin and Schlesinger found that the neutralizing antibodies which developed following

Prevalence of antibodies to Chlamydophila abortus in ovines in the Londrina area of Paraná state, Brazil

Semina: Ciências Agrárias, 2014
The aim of this paper was to estimate the prevalence of antibodies to Chlamydophila abortus in ewes from the Londrina region of Paraná state. Blood samples from 267 adult ewes from eight herds were submitted to complement fixation testing.

Study on small ruminant brucellosis and owners awareness in two selected districts of southern region, Ethiopia

Veterinary Medicine and Science, 2023
Introduction Brucellosis is one of the infectious diseases that has the greatest impact on the productivity of sheep and goats. A cross‐sectional study followed by a simple random sampling technique was used to investigate the seroprevalence of ...

Yersinia enterocolitica serotype O:9 cultured from Swedish sheep showing serologically false-positive reactions for Brucella melitensis [PDF]

Infection Ecology & Epidemiology, 2012
In a herd of 20 sheep in Sweden, a country where brucellosis has never been diagnosed in sheep or goats, a total of six sheep were found serologically positive to Brucella melitensis in two different rounds of sampling. Yersinia enterocolitica serotype O:

The power of microRNA regulation—insights into immunity and metabolism

FEBS Letters, EarlyView.
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair

FEBS Letters, EarlyView.
miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Lewis X antigen mediates adhesion of human breast carcinoma cells to activated endothelium. Possible involvement of the endothelial scavenger receptor C-Type lectin [PDF]

, 2007
Lewis x (Lex, CD15), also known as SSEA-1 (stage specific embryonic antigen-1), is a trisaccharide with the structure Galβ(1–4)Fucα(1–3)GlcNAc, which is expressed on glycoconjugates in human polymorphonuclear granulocytes and various tumors such as colon

Estabilidade do antígeno de célula total de Brucella abortus para uso no diagnóstico sorológico da brucelose bovina pela reação de fixação de complemento Stability of Brucella abortus whole cell antigen for use in the serological diagnosis of bovine brucellosis by the complement fixation test

Pesquisa Veterinária Brasileira, 2007
A reação de fixação de complemento é um dos testes usados no diagnóstico confirmatório da brucelose bovina, e para sua realização emprega-se o mesmo antígeno usado na prova de soroaglutinação lenta, porém não foi possível encontrar na literatura estudos ...

A stepwise emergence of evolution in the RNA world

FEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to
