Homologue synapsis is required for meiotic chromosome segregation, but how synapsis is initiated between chromosomes is poorly understood. In Caenorhabditis elegans, synapsis and a checkpoint that monitors synapsis depend on pairing centers (PCs), cis-acting loci that interact with nuclear envelope proteins, such as SUN-1, to access cytoplasmic microtubules. Here, we report that spindle assembl...

The BMP ligand Dpp, operates as a long range morphogen to control many important functions during Drosophila development from tissue patterning to growth. The BMP signal is transduced intracellularly via C-terminal phosphorylation of the BMP transcription factor Mad, which forms an activity gradient in developing embryonic tissues. Here we show that Cyclin dependent kinase 8 and Shaggy phosphor...

BACKGROUND Mitral annular disjunction (MAD) consists of an altered spatial relation between the left atrial wall, the attachment of the mitral leaflets, and the top of the left ventricular (LV) free wall, manifested as a wide separation between the atrial wall-mitral valve junction and the top of the LV free wall. Originally described in association with myxomatous mitral valve disease, this ab...

An embeddable and portable Lex-based MAD language parser has been developed. The parser consists of a frontend which reads a MAD file and keeps beam elements, beam line data and algebraic expressions in tree-like structures, and a back-end, which processes the front-end data to generate an input file or data structures compatible with user applications. Three working programs are described, nam...

The mad spectrum is the set of all cardinalities of infinite maximal almost disjoint families on ω. We treat the problem to characterize those sets A which, in some forcing extension of the universe, can be the mad spectrum. We give a complete solution to this problem under the assumption θ = θ, where θ = min(A). §0. Introduction. Recall that A ⊆ [ω] is called almost disjoint (a. d. for short),...

AIMS The planimetry method using three-dimensional (3D) echocardiography is useful for providing an accurate mitral annulus area (MAA) value. However, this method is relatively unavailable. Therefore, we evaluated the accuracy of conventional methods for MAA measurement compared with that of 3D planimetry. METHODS AND RESULTS Two-dimensional (2D) and 3D transoesophageal echocardiography (TEE)...

BACKGROUND Some honey types in certain geographical regions may cause toxic effects on people. This type of honey is known as "mad honey" in Turkey. The toxic ingredient of this honey is called Grayanotoxin I. The consumption of mad honey can cause severe bradycardia, hypotension, dizziness, nausea and vomiting. AIMS Our study is aimed at analysing patients diagnosed with mad honey poisoning ...

A prospective study was undertaken from April 1988 to April 1989, to assess the diarrheal and respiratory complications of measles. Standard definitions were used for the cases, Measles Associated Diarrhea (MAD) and Measles Related Pneumonia (MRP). Children with diarrhea not related to measles were recruited for comparison for MAD. There was a total of 454 cases, measles 53 (11.7%), measles ass...

Purpose. To analyze in mild Alzheimer's disease (MAD) patients, GDS-4 (Reisberg Scale), whether or not some psychophysical tests (PTs) support OCT macular findings in the same group of MAD patients reported previously. Methods. Twenty-three MAD patients and 28 age-matched control subjects with mean Mini Mental State Examination of 23.3 and 28.2, respectively, with no ocular disease or systemic ...

The members of the Myc/Max/Mad network function as transcriptional regulators. Substantial evidence has been accumulated over the last years that support the model that Myc/Max/Mad proteins affect different aspects of cell behavior, including proliferation, differentiation, and apoptosis, by modulating distinct target genes. The unbalanced expression of these genes, e.g. in response to deregula...
