Our goal is to understand the assembly and regulation of flagellar dyneins, particularly the Chlamydomonas inner arm dynein called I1 dynein. Here, we focus on the uncharacterized I1-dynein IC IC97. The IC97 gene encodes a novel IC without notable structural domains. IC97 shares homology with the murine lung adenoma susceptibility 1 (Las1) protein--a candidate tumor suppressor gene implicated i...

To understand the mechanisms that regulate the assembly and activity of flagellar dyneins, we focused on the I1 inner arm dynein (dynein f) and a null allele, bop5-2, defective in the gene encoding the IC138 phosphoprotein subunit. I1 dynein assembles in bop5-2 axonemes but lacks at least four subunits: IC138, IC97, LC7b, and flagellar-associated protein (FAP) 120--defining a new I1 subcomplex....

We adopt the following rules: r, x, y are real numbers, i, j are natural numbers, and p is a finite sequence of elements of R. The following proposition is true (1) For every closed-interval subset A of R and for every x holds x ∈ A iff inf A ¬ x and x ¬ supA. Let I1 be a finite sequence of elements of R. We say that I1 is non-decreasing if and only if the condition (Def. 1) is satisfied. (Def....

In this paper the discrete Fourier transform is used to determine the coefficients of a transfer function of a new twodimensional model of second-order: x(i1 +2, i2 +2) = A0x(i1 +1, i2 +1)+A1x(i1 +1, i2)+A2x(i1, i2 +1). The algorithm is straightforward and has been implemented using the software package Matlab . Two step-by-step examples illustrating the application of the algorithm are presented.

The ideal I1 generated by the 2× 2 quantum minors in the coordinate algebra of quantum matrices, Oq(Mm,n(k)), is investigated. Analogues of the First and Second Fundamental Theorems of Invariant Theory are proved. In particular, it is shown that I1 is a completely prime ideal, that is, Oq(Mm,n(k))/I1 is an integral domain, and that Oq(Mm,n(k))/I1 is the ring of coinvariants of a coaction of k[x...

Previous studies have shown that angiotensin I1 increases aldosterone biosynthesis, but the mechanisms involved have not been clearly defined. The present studies were carried out to examine the effects of angiotensin I1 on cytochrome P-450 enzymes of the rat adrenal cortex. Microsomal and mitochondrial cytochrome P-450 levels in the zona glomerulosa were not affected by angiotensin I1 administ...

Plastic mulched ridge-furrow irrigation is a useful method to improve crop productivity and decrease salt accumulation in arid saline areas. However, inappropriate fertilizer practices may result ecological environmental problems. In order the resource use efficiency these areas, we investigated effects of different amounts (400 (I1), 300 (I2) 200 (I3) mm) nitrogen application rates (300 (F1) 1...

1. Angiotensin I1 was infused into isolated, perfused pig carotid arteries. The perfusate leaving the arteries was sampled into an Auto-analyzer system which continuously monitored its composition. Arterial pressure was recorded. 2. Low, subpressor doses of ygiotensin I1 raised the perfusate potassium concentration, whereas high doses, which produced contraction, lowered perfusate potassium and...

A series of Schiff Bases of Ni(II) and Cu(II) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. The electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of Cu(II) shifts to red with the increase of the Donor Number (DN) of solvent. The ...
