most of the free amino acids present in plasma to be assayed with relative simplicity. However, tryptophan determination is difficult by these methods because of its rapid destruction in an acid medium. This fact creates a serious problem when it is necessary to know the complete plasma amino acid pattern in nutrition experiments or Some clinical studies. This circumstance led us to study a use...

Medial entorhinal cortex Layer-II stellate cells (mEC-LII-SCs) primarily interact via inhibitory interneurons. This suggests the presence of alternative mechanisms other than excitatory synaptic inputs for triggering action potentials (APs) in stellate cells during spatial navigation. Our intracellular recordings show that the hyperpolarization-activated cation current (Ih) allows post-inhibito...

In all mammalian females, follicular growth and maturation are essentially dependent on the pituitary gonadotropins, FSH and LH. These glycoprotein hormones have many similarities, but their actions, based on high affinity binding to specific membrane receptors, are quite different. The purpose of this study was to perform a sensitive localization of FSH and LII in secretory granules of gonadot...

Listeria monocytogenes is a food-borne bacterial pathogen and the causative agent of human and animal listeriosis. Among the three major genetic lineages of L. monocytogenes (i.e., LI, LII, and LIII), LI and LII are predominantly associated with food-borne listeriosis outbreaks, whereas LIII is rarely implicated in human infections. In a previous study, we identified a Crp/Fnr family transcript...

We have examined the ability of two purified peptide fragments derived from hen (chicken) egg-white lysozyme (HEL); N-terminal, Co-terminal peptide (a.a. 1--17:cys 6--cys 127:120--129) and mixed disulfide LII peptide (LII) (a.a. 13--105) to induce antigen-specific suppression or help in B10 (H-2b) nonresponder and B10.A (H-2a) responder mice. An anti-HEL primary in vitro antibody response can b...

In order to evaluate the relationship between acetabular and proximal femoral alignment in the initiation and evolution of osteoarthritis of the dysplastic hip, the acetabular and femoral angles were calculated geometrically from radiographs of 62 patients with pre-arthrosis and early osteoarthritis. The sum of the lateral opening angle of the acetabulum and the neck-shaft angle was defined as ...

Three new species of Pardosa, P. svatoni sp. n. (dy, SE Kazakhstan), P. fengisp. n. (male female, Central Xinjiang) and P lii sp. n. (male female, Central Xinjiang) are described and illustrated. The two former species cannot be placed in any species group. Pardosa lii sp. n. belongs to the P. wagleri species group. It is compared with P. italica Tongiorgi, 1966, whose embolic division has not ...

We have undertaken a preliminary study of Laser-Induced Incandescence (LII) using carbon black in high vacuum (circa 5×10 mbar). Our aim was to understand the temperature behaviour of carbon nanoparticles under conditions dominated by radiative cooling. We have found that under these conditions the signal from LII is markedly enhanced (over 2,000 times) and that cooling behaviour can be measure...

To date nearly all LII is carried out using Q-switched, flashlamp pumped Nd/YAG lasers with pulse lengths ~10 ns. Although these lasers are well developed and readily available for use in the laboratory and in commercial instruments, they are bulky, inefficient and often the most costly part of an LII system. Cheaper, more compact lasers are becoming available, but very few are able to match th...
