The conformation of the L-iduronate residue in non-sulphated di-, tetra- and hexa-saccharides and their alditol derivatives derived from rooster comb dermatan sulphate was investigated by 400 MHz 1H-n.m.r. spectroscopy. The ratio of conformational isomers is obtained by the average spin-spin coupling constants of a mixture of nearly isoenergetic conformers (1C4, 4C1 and 2S0). The non-reducing t...

Olive pomace (OP) is the main by-product of olive oil industry produced in large quantities. Its valorization as a source phenolic bioactive compounds paramount for sustainable growth related industries. This work proposes an intensified process to maximize recovery dry extracts using hydroalcoholic mixtures. Supercritical carbon dioxide defatting pre-treatment was performed. Following this, pr...

3,7-Dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were identified in female whole body extracts from the two pine sawfly species Gilpinia frutetorum and Gilpinia socia. This is the first observation of 3-methylpentadecan-2-ol in extracts of a female pine sawfly species. Synthetic and highly pure stereoisomers of 3,7-dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were used to verify t...

Oligodendrocytes (OLs), the myelin-forming CNS glia, are highly vulnerable to cellular stresses, and a severe myelin loss underlies numerous CNS disorders. Expedited OL regeneration may prevent further axonal damage and facilitate functional CNS repair. Although adult OL progenitors (OPCs) are the primary players for OL regeneration, targetable OPC-specific intracellular signaling mechanisms fo...

In this work, the enzymatic synthesis of pentyl acetate obtained from acetic acid and pentan-1-ol using commercial immobilized lipase Lipozyme®435 was studied. Specifically, effects several variables process on kinetics were shown, such as initial concentration acid, alcohol/acid molar ratio, possible reuse enzyme, while other variables, temperature, agitation, enzyme/acid ratio held constant. ...

purpose: to introduce the importance and world prevalence of ocular leishmaniasis (ol), its clinical manifestations, and diagnostic and management features with more emphasis on iranian cases. methods: we reviewed all available articles published about ol during recent 50 years. results: ol is an ocular protozoal infection which is widespread in the world but is more common in developing countr...

When Chlorella sorokiniana was cultured in the presence of 1 mg/1 triparanol succinate, there was a 42% reduction in total sterol concentration. Algal biomass was reduced by approximately the same amount. In addition to the cycloartenol, cyclolaudenol, 24-methyl-pollinastanol, ergosta-5, 7-dien-3beta-ol, and ergosterol that occur in control culture, pollinastanol, 14alpha-methyl-5alpha-ergost-8...

The present study addresses the short-term effects of different harvest intensities under close-to-nature selective management on upper soil layers in Slovenian and Bosnian Dinaric karst fir-beech forests. coincided with single-tree irregular shelterwood management, common region. effect harvesting intensity (Ol, Of, Ol 0–10 cm mineral soil) was investigated by a repeated measurements experimen...

Microbial volatile organic compounds (MVOCs) are a type of VOCs produced by microorganisms. Exposure to 1-octen-3-ol, one of the known MVOCs, has been reported to reduce nasal patency and increase nasal lavage myeloperoxidase, eosinophil cationic proteins, and lysozymes in both experimental and field studies. We reported in a previous paper that 1-octen-3-ol exposure at home is associated with ...
