Area-efficient architectures for integrated N-port memories employ blocks of one port memory cells and dynamic port-to-block connections. The authors determine the block number M necessary to achieve a target port-access-rejection probability for a given port number N and best-case/worst-case conflict-resolve algorithms, by applying stochastic probability theory.
Three patients with contracted bladder caused by neurogenic bladder underwent ileocystoplasty. The primary diagnosis was meningomyelocele for all of them. The operative procedure adopted was Goodwin's Cup-patch method. All cases have obtained increased bladder capacity with improvement of bladder compliance and have been free from urinary incontinence. They were followed up by using clean intermittent self catheterization. Ileocystoplasty combined with clean intermittent self catheterization offers a successful method in patients with contracted bladder caused by neurogenic bladder.
The presence and the absence of a prokaryote type and a eukaryote type of acetyl-CoA carboxylase (EC 6.4.1.2; ACCase) were examined in members of 28 plant families by two distinct methods: the detection of biotinylated subunits of ACCase with a streptavidin probe, and the detection of the accD gene, which encodes a subunit of the prokaryotic ACCase, by Southern hybridization analysis. The protein extracts of all the plants studied contained a biotinylated polypeptide of 220 kDa, which was probably the eukaryotic ACCase. All the plants but those belonging to Gramineae also contained a biotinylated polypeptide of ca. 35 kDa, which is a putative subunit of the prokaryotic ACCase. In all plants but those in Gramineae, the ca. 35 kDa polypeptide was found in the protein extracts of plastids, while the 220 kDa polypeptide was absent from these plastid extracts. The plastid extracts of the plants in Gramineae contained the 220 kDa polypeptide, as did the homogenates of the leaves. Southern hybridization analysis demonstrated that all the plants but those in the Gramineae contained the accD gene. These findings suggest that most higher plants have the prokaryotic ACCase in the plastids and the eukaryotic ACCase in the cytosol. Only Gramineae plants might contain the eukaryotic ACCases both in the plastids and in the cytosol. The origin of the plastid-located eukaryotic ACCase in Gramineae is discussed as the first possible example of substitution of a plastid gene by a nuclear gene for a non-ribosomal component.
We have isolated two cDNA clones (CDES01 and 04) encoding stearoyl-acyl carrier protein desaturase (SACPD; EC 1.14.99.6) from immature sesame seeds, and have analyzed accumulation levels of the corresponding mRNAs at different stages and organs in sesame. Clone CDES01 contains an open reading frame coding for a 396-amino acid protein of 45 kDa. CDES04 encodes a partial sequence of 141-amino acids. Deduced amino acid sequences of both clones exhibit a high identity to those of other plant SACPD cDNAs. Northern blots probed with CDES01 and CDES04 indicate that both messages accumulate in a seed-specific manner with a peak at 21 days after anthesis. However, expression patterns also indicate that regulation between CDES01 and CDES04 are slightly different. The CDES01 message accumulates at a low level in young leaves in addition to seeds, whereas accumulation of the RNA transcript corresponding to CDES04 is restricted to seeds. This observation implies the presence of at least two isozymes of SACPD having overlapping but slightly distinct functions in sesame.
The limitation of detectability and curability in terms of current techniques (screening and details) were sought in otherwise healthy examinees. Not a few cancers were present in the alimentary tract, except for the stomach, in these otherwise healthy examinees who voluntarily underwent gastric cancer mass screening. The prognosis of alimentary tract cancers deteriorates in the descending, following order: colon cancer, stomach cancer, and esophageal cancer. The survival rate of primary liver cancer, cholecyst cancer, and pancreas cancer is extremely low. Unless new techniques are developed in these diagnoses, no improvement in the survival rate can be anticipated.

N-port memories are attractive, because in comparison to 1-port memories a large access bandwidth without latency is possible even at low clock frequencies. However, dynamical management of unavoidable access conflicts becomes necessary. We present an area-efficient conflict-management concept, which can be generally applied for N-port memories, and a circuit implementation in 0.5µm CMOS technology. Small circuit sizes (≤0.052 mm2) and short delay times (≤1.1ns) are achieved with best-case as well as worst-case conflict-regulation algorithms for a hierarchical 4-port memory with low (<0.05) access-rejection probability. The small circuit sizes enable applicability of the new hierarchical N-port memory architecture [1] for storage capacities down to 4Kbit. Multi-GBit/s latency-free access to a 4-port memory is already possible at clock frequencies well below 100MHz.
