Channel systems

Drug therapy to achieve the recommended target blood pressure remains the cornerstone of the management of hypertension. Today, there are strong evidences from randomized controlled trials that antihypertensive drugs are more effective than placebo at reducing cardiovascular mortality and morbidity.

This thesis attempts to address the problem of how best to remedy different types of channel distortions on speech when that speech is to be used in automatic speaker recognition and verification systems. Automatic speaker recognition is when a person's voice is analysed by a machine and the person's identity is worked out by the comparison of speech features to a known set of speech features. Automatic speaker verification is when a person claims an identity and the machine determines if that claimed identity is correct or whether that person is an impostor.

This project is focused on studying the biological effects of low-power RF radiation on the expression and function of mechanosensitive ion channel protein (Piezo-1). To evaluate the effects of long-term exposures, cells were exposed at the frequency of 1800 MHz and power of 17 dBm for a period of 2 and 4 hrs using the transverse electromagnetic (TEM) cell exposure system. To study the effects of short-term RF radiation (10 min), exposures emitted from the mobile phone headset at the frequency of 845 MHz and powers of -15 dBm and -5 dBm were applied to cell cultures.

Multimolecular complexes involving the eukaryotic elongation factor 1A (eEF1A) have been suggested to play an important role in the channeling (vectorial transfer) of tRNAduring protein synthesis [Negrutskii, B.S.&El’skaya, A.V. (1998)Prog. Nucleic Acids Res. Mol. Biol.60,47–78]. Recently we have demonstrated that besides performing its canonical function of forming a ternary complex with GTP and aminoacyl-tRNA, the mammalian eEF1A can produce a noncanonical ternary complex with GDP and uncharged tRNA [Petrushenko, Z.M., Negrutskii, B.S.,...

Aquaporin adipose (AQPap), which we identi®ed from human adipose tissue, is a glycerol channel in adipocyte [Kishida et al. (2000) J. Biol. Chem.275, 20896±20902]. In the current study, we determined the genomic structure of the human AQPap gene, and identi®ed three AQPap-like genes that resembled (95%)AQPap, with little expression in human tissues.

The Hitachi SV1100 utilizes capillary electrophoresis on a microchip that is capable of rapidly sizing DNAfrag-ments. Reproducibility of electrophoresis in different channels was shown by comparing the migration times of the internal controls, DNAfragments of 100 and 800 bp. The range of DNAsizing for this microchip is between 100 and 800 bp, and accuracy in sizing of a 322 bp DNA fragment of a pUC118 PvuII digest was observed, inde-pendent of DNAconcentration. Although relatively good quantification of this fragment was observed with a DNA concentration of 1.

Endovanilloids are defined as endogenous ligands of the transient receptor potential vanilloid type 1 (TRPV1) protein,a nonselective cation channel that belongs to the large family of TRP ion channels,and is activated by the pungent ingredient of hot chilli peppers,capsaicin. TRPV1 is expressed in some nociceptor efferent neurons, where it acts as a molecular sensor of noxious heat and low pH. However,the presence of these channels in var-ious regions of the central nervous system,where they are not likely to be targeted by these noxious stimuli,suggests the existence of endovanilloids.

Another class of linear codes, known as Convolutional codes. We study the structure of the encoder. We study different ways for representing the encoder.Convolutional codes offer an approach to error control coding substantially different from that of block codes. A convolutional encoder: encodes the entire data stream, into a single codeword. does not need to segment the data stream into blocks of fixed size (Convolutional codes are often forced to block structure by periodic truncation). is a machine with memory.

Protein kinase Ce is expressed at higher levels in the brain compared to other tissues such as the heart and kidney, suggesting that it plays an important role in the nervous system. Several neural functions of PKCe, including neurotransmitter release and ion channel regulation, have been identified using PKCe knockout mice.

Cone snails, a group of gastropod animals that inhabit tropical seas, are capable of producing a mixture of peptide neurotoxins, namely conotoxins, for defense and predation. Conotoxins are mainly disulfide-rich short pep-tides that act on different ion channels, neurotransmitter receptors, or transporters in the nervous system.

Src family kinases (SFKs) play critical roles in the regulation of many cellular functions by growth factors, G-protein-coupled receptors and ligand-gated ion channels. Recent data have shown that SFKs serve as a convergent point of multiple signaling pathways regulating N-methyl-D-aspartate (NMDA) receptors in the central nervous system.
