This study evaluated sex-related differences in the tibialis anterior (TA) surface
electromyography (EMG) to force relationship. One-hundred participants (50 males and
50 females) performed three isometric contractions ...
The Dummer Complex extends 180 km along the Precambrian -
Paleozoic contact from Tamworth to Lake Simcoe. It is composed
of coarse, angular Paleozoic clasts in discontinuous, pitted, hummocky
deposits. Deposits are ...
It was the purpose of this study to investigate
attitudes toward leadership development education of one
client group served by the ontario Ministry of Agriculture
and Food. The survey, answered by 175 participants,
attempted ...
Most human genes undergo alternative splicing and loss of splicing fidelity is
associated with disease. Epigenetic silencing of hMLH 1 via promoter cytosine
methylation is causally linked to a subset of sporadic non-polyposis ...
This qualitative inquiry explored 7 undergraduate students' attitudes, habits, and
knowledge of consumerism, fashion design, and sustainability. The postmodern study
employed crystallization as its methodological framework ...

Phycobilisomes are the major light harvesting complexes for cyanobacteria and
phycocyanin is the primary phycobiliprotein of the phycobilisome rod. The
phycocyanobilin lyases responsible for chromophorylating the phycocyanin ...
Since its discovery nearly a century ago, a-tocopherol (vitamin E) research has
been mainly focused on its ability to terminate the cycle of lipid peroxidation in
membranes. Nitrobenzoxadiazole fluorescent analogues were ...
The synthesis and studies of two classes of poly dentate ligands are presented as two
projects. In project 1, four new carboxamide ligands have been synthesised via the
condensation of 2,2',6,6'-tetrachloroformyl-4,4'-bipyridine ...
The work herein has been divided into five sections.
In the first section, a new method of converting N-aroyl-
hydrazines to hydrazidic halides is described.
The second section deals with the products of reaction
of ...
2-Carboxy-2?-methyldiphenyl sulfide was prepared by the Ullmann
reaction and cyclodehydrated by sulfuric acid to afford 4-methylthioxanthone.
1-Methylthioxanthone was separated from the reaction
mixture obtained upon ...
Development of guanidine catalysts is explored through direct iminium chloride and
amine coupling, alongside a 2-chloro-l,3-dimethyl-IH-imidazol-:-3-ium chloride (DMC)
induced thiourea cyclization. Synthesized achiral ...

The monoconjugates of phenolic acids (i.e. coumaric acid) with polyamines
such as spermidine and spermine are strikingly similar to some toxins from
spiders and predatory wasps. Many plants contain phenolic acid ...
Since its discovery in 1922, vitamin E has been widely investigated for its role as a
powerful, chain-breaking antioxidant that is required for human health. However, some
basic issues still remain unclear, such as the ...
A^-heterocyclic carbenes (NHCs) have become the focus of much interest as ancillary
ligands for transition metal catalysts in recent years. Their structural variability and strong
cy-donation properties have led to the ...
The implementation of chiral centres within biologically active compounds has
been a perplexing yet motivational force in chemistry. This work presents the
attempted formation of a concurrent or sequential tandem catalyzed ...
Vitamin E is a group of eight different tocopherols and tocotrienols distinguished by the
degree of methylation of the aromatic ring. The North American diet contains more ytocopherol than the more ...
To further understand in vivo localization and trafficking of a-tocopherol (a-Toe), the most
biologically active form of vitamin E, between lipid environments, tocopherols are required that
can be followed by teclu1iques ...
Ionizing radiation is known to initiate apoptosis in mammalian cells by causing the transformation of cytochrome c into a peroxidase, which results in the specific peroxidation of the mitochondrial phospholipid cardiolipin. ...
