A case of simultaneous acute cardio-cerebral infarction in a woman with essential thrombocythemia.

Essential thrombocythemia (ET) can cause arterial embolism. Patients with arterial thrombosis usually have additional risk factors, such as smoking and hypertension. We report a 70-year-old woman with ET who had no risk factors, except for age.

Acute myocardial infarction in pregnancy: spasm caused by hyperthyroidism?

We present a 26-year-old woman with ST-segment elevation myocardial infarction in the 14th week of pregnancy. Coronary angiography revealed no abnormalities in the coronary arteries. She had no history of coronary risk factors such as smoking, diabetes mellitus, hypertension, or dyslipidemia.

The function of PlcR in Bacillus anthracis vaccine strain A16R.

Bacillus anthracis, B. thuringiensis and B. cereus are members of the B.

Identification of loss of function mutations in human genes encoding RIG-I and MDA5: implications for resistance to type I diabetes.

Retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated gene 5 (MDA5) are essential for detecting viral RNA and triggering antiviral responses, including production of type I interferon. We analyzed the phenotype of non-synonymous mutants of human RIG-I and MDA5 reported in databases by functional complementation in cell cultures. Of seven missense mutations of RIG-I, S183I, which occurs within the second caspase recruitment domain repeat, inactivated this domain and conferred a dominant inhibitory function.

Construction of a novel Shigella live-vector strain co-expressing CS3 and LTB/STm of enterotoxigenic E.coli.

Aim: To construct and evaluate a polyvalent recombinant vaccine strain Shigella flexneri 2a T32 against enterotoxigenic E.coli (ETEC).

Methods: By using a host-plasmid balanced lethal system based on asd gene, a polyvalent recombinant strain was constructed to highly express CS3 and regularly express fusion enterotoxin of LTB subunit and mutant ST (LTB/STm) in a vaccine strain Shigella flexneri 2a T32 with specific deletion of asd gene.

[Co-expression of CFA/I and CS6 of Enterotoxigenic Escherichia coli ( ETEC ) in Shigella flexneri 2a T32 Derivative Strain FWL01].

Among the known colonization factors of enterotoxigenic Escherichia coli (ETEC), CFA/I and CS6 (the common antigen in the CFA/IV fimbrial antigens ) are two of the most prevalent fimbriae found in clinical isolates but are never expressed by the same wild-type strains. In this study, CFA/I and CS6 of ETEC were co-expressed in Shigella flexneri 2a T32 derivative strain FWL01 by using a host-plasmid lethal balancing system based on asd gene. The results indicate that the recombinant plasmid carrying CFA/I and CS6 could be stably integrated in FWL01.

Enterotoxigenic Escherichia coli (ETEC) causes watery dehydrating diarrhea in infants in developing countries, and is the most common cause of travelers diarrhea. It has been known that the colonazition factor antigens (CFAs) and enterotoxins are important virulence factors of ETEC, and these two kinds of proteins should be included in any effective vaccine against ETEC. In this study, a host-plasmid lethal balancing system was constructed based on asd gene in an avirulent strain of S.
