We report the sequence of several MALactivator genes, including inducible, constitutive, and noninducible alleles of MAL23, MAL43, MAL63, and ma164. Constitutive alleles of MAL23 and MAL43 vary considerably from inducible alleles in their C-terminal domain, with many of the alterations clustered and common to both alleles. The 27 alterations from residues 238-461 of Ma143-C protein are sufficie...

dS values in gypsum are used to evaluate the fate of sulfur in the hypersaline Lake Lisan, the late Pleistocene precursor of the Dead Sea (70–14 ka BP), and applied as a paleo-limnological tracer. The Ca-chloride Lake Lisan evolved through meromictic periods characterized by precipitation of authigenic aragonite and holomictic episodes characterized by enhanced gypsum precipitation. The lake de...

Despite many different studies and metaanalyses, there is no universal agreement about the optimal management strategy of acute total Achilles tendon rupture. Most authors prefer open surgical repair as it contributes to a low incidence of re-rupture, ranging from 1,4% to 2,8% (Cetti et al., 1993; Inglis & Sculco, 1981; Lo et al., 1997; Maffulli, 1999; Thermann & Zwipp, 1989; Wills et al. 1986)...

Protein kinase C (PKC) is a multifunctional serine/threonine specific protein kinase, first described by Nishizuka and colleagues (Takai et d., 1977), that is dependent upon Ca2+, phospholipid and diacylglycerol (recently reviewed Nishizuka 1986; Woodgett et af., 1987). The enzyme is widely distributed and has been purified to apparent homogeneity from a number of sources (see Woodgett et al., ...

The effects of time, concentration, and pH on glutaraldehyde ( GA) fixation were studied in vitro using 2 model systems: coIlagen-BSA gels as simulations of cell cytoplasm and enzyme activity in treated pulp tissue. The former system demonstrated that GA is most effective when buffered, and that its penetration is self-limiting. In general, concentration proved more a factor in the depth of pen...
