Myocardial Infarction as a Complication of Bronchial Artery Embolization.

Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles.

Comparability of imazapyr-resistant Arabidopsis created by transgenesis and mutagenesis.

The Arabidopsis CSR1 gene codes for the enzyme acetohydroxyacid synthase (AHAS, EC 2.2.1.

Role of HD2 genes in seed germination and early seedling growth in Arabidopsis.

The Arabidopsis HD2 family of histone deacetylases consist of 4 members (HD2A, HD2B, HD2C, HD2D) that play diverse roles in plant development and physiology through chromatin remodelling. Here, we show that the transcripts of HD2 family members selectively accumulate in response to glucose through a HXK1-independent signal transduction pathway during the early stages of seedling growth. Germination was enhanced in hd2a null mutants relative to wild-type seeds.

Control of somatic embryogenesis and embryo development by AP2 transcription factors.

Members of the AP2 family of transcription factors, such as BABY BOOM (BBM), play important roles in cell proliferation and embryogenesis in Arabidopsis thaliana (AtBBM) and Brassica napus (BnBBM) but how this occurs is not understood. We have isolated three AP2 genes (GmBBM1, GmAIL5, GmPLT2) from somatic embryo cultures of soybean, Glycine max (L.) Merr, and discovered GmBBM1 to be homologous to AtBBM and BnBBM.

Evidence that the hexose-to-sucrose ratio does not control the switch to storage product accumulation in oilseeds: analysis of tobacco seed development and effects of overexpressing apoplastic invertase.

Wild-type tobacco (Nicotiana tabacum L.) seed development was characterized with respect to architecture and carbohydrate metabolism. Tobacco seeds accumulate oil and protein in the embryo, cellular endosperm and inner layer of the seed coat.
