The reaction of furylacrylic acid with cyclopentadiene in toluene gave the expected Diels-Alder endo-and exo-adductsin -1 : 1 ratio. The adducts were separated by iodolactonization method to provide 3-endo-(2'-furyl) bicyclo 12.2.11 hept-5-ene- 2-exo-carboxylic acid and 3-exo-(2'-fury1)bicyclo 12.2.11 hept-5-ene-2-endocarboxylic acid. Esterification of these acids by MeI / HMPA gave the exp...

Purification of extra-cellular cellulolytic enzymes from C e l l u l o mssp. strain 0, isolated from forest soil in the north of Iran , was studied by using gel filtration and ion-exchange chromatography. Two endo-glucanases (Endo-I & Endo-II) and one exo-glucanase (Exo-I) were purified to hornogenity . The purified enzymes had molecular weights of about 39.000,70.000 and 90.000 daltons for ...

Cellulase production by a Cellulomonas sp., isolated in 1985 from forest humus soil along the border of the Caspian Sea in Iran, was investigated. This strain secreted endo-and exo-cellulases in the culture medium, but some of the enzymes produced remained cell membrane bound. Cell bound enzymes were released by various treatments. The highest amount of endo-glucanase (up to 95%) and exo-gl...

Cardiosphere-derived cells (CDCs) have emerged as one of the most promising stem cell types for cardiac protection and repair. Exosomes are required for the regenerative effects of human CDCs and mimic the cardioprotective benefits of CDCs such as anti-apoptotic effect in animal myocardial infarction (MI) models. Here we aimed to investigate the anti-apoptotic effect of the hypoxic and normoxic...

Background: The EXO (EXORDIUM) gene was identified as a potential mediator of brassinosteroid (BR)-promoted growth. It is part of a gene family with eight members in Arabidopsis. EXO gene expression is under control of BR, and EXO overexpression promotes shoot and root growth. In this study, the consequences of loss of EXO function are described. Results: The exo loss of function mutant showed ...

The influence of the substituent at the C2 position on the hydrogen-bonding patterns is compared for a series of five related compounds, namely (±)-3-exo,6-exo-dibromo-5-endo-hydroxy-3-endo-nitrobicyclo[2.2.1]heptane-2-exo-carbonitrile, C(8)H(8)Br(2)N(2)O(3), (II), (±)-3-exo,6-exo-dibromo-6-endo-nitro-5-exo-phenylbicyclo[2.2.1]heptan-2-endo-ol, C(13)H(13)Br(2)NO(3), (III), (±)-methyl 3-exo,6-ex...

MicroRNAs (miRNAs) are small regulatory RNAs that play important roles in animals, plants, and viruses. Deep-sequencing technology has been widely adopted in miRNA investigations. However, it is still a big mysterious why nearly all sequencing data contain miRNA sequences from exogenous species, called exo-miRNAs. In this study, we developed a novel platform, exo-miRExplorer, for mining and ide...

We investigate the non-resonant evolution of axial tilt hypothetical exo-Earth in gravitational field a star, planet's satellite (exo-Moon) and outer planet (exo-Jupiter). The is assumed to be rigid, axially symmetric ($A=B$) almost spherical. assume orbits both exo-planets Keplerian ellipses with focus orbit exo-Moon an evolving ellipse slowly changing ascending node longitude periapsis argume...
