STUDY DESIGN A retrospective study. OBJECTIVE The aim of this study was to investigate the correlation between pelvic incidence (PI) and lumbar lordosis (LL) mismatch and knee flexion during standing in patients with lumbar degenerative diseases and to examine the effects of surgical correction of the PI-LL mismatch on knee flexion. SUMMARY OF BACKGROUND DATA Only several studies focused on...

A transition from constant light (LL) to constant darkness (DD) will reset the circadian rhythms of most organisms to a phase that normally occurs near dusk. We tested the circadian oscillator in the Aplysia eye for this property. The test was run in vitro under two conditions. Using the two eyes of a single animal, one eye was left attached to the cerebral ganglion by its intact optic nerve an...

LL-23 is a natural peptide corresponding to the 23 N-terminal amino acid residues of human host defense cathelicidin LL-37. LL-23 demonstrated, compared to LL-37, a conserved ability to induce the chemokine MCP-1 in human peripheral blood mononuclear cells, a lack of ability to suppress induction of the pro-inflammatory cytokine TNF-α in response to bacterial lipopolysaccharides (LPS), and redu...

Background: Hydatid disease is characterized by long-term growth of hydatid cysts in the human. The glycan antigens have an important role in the immunology of hydatid cyst. In this study immunological reaction of host sera to different glycan antigens of the cyst, has been investigated. Methods: The antibody responses were tested to glycoprotein and glycolipid of the laminated layer (LL), c...

L-Lactate (LL) is an essential cellular metabolite which can be used to generate energy. In addition, accumulating evidence suggests that LL is used for inter-cellular signalling. Some LL-sensitive receptors have been identified but we recently proposed that there may be yet another unknown G-protein coupled receptor (GPCR) sensitive to LL in the brain. Olfactory receptors (ORs) represent the l...

— In this paper it is shown that it is possible to transform any LL-regular grammar G into an LL{\) grammar G' in such a way that parsing G' is as good as parsing G. That ist a par se of a sentence of grammar G can be obtained with a simple string homomorphism from the parse of a corresponding sentence of G'. Since any LL (k) grammar is an LL-regular grammar the results which are obtained are v...
