Lamb’s quarters goosefoot (with scientific name “Chenopodium album L.”) can absorb and purify heavy metals from environment. Cesium is one of pollutant and basic elements. Due to similarity to potassium, it can be absorbed by plants intensively. According to its absorption from the environment, cesium effect on anatomical and ontogenical structure of plant was studied. For this purpose, plant s...

Effect of salts (Na2SO4, Na2CO3, MgSO4, NaCl, MgCl2), soil extract and polyethylene glycol (PEG-6000) on the germination of Chenopodium glaucum L., seed was studied. Maximum germination was obtained in distilled water. Germination decreased with increase in salinity. The inhibition of germination by salt solutions was in the order of MgCl2 > Na2SO4 > Na2CO3 > NaCl > Soil extract > MgSO4. Germin...

Periplaneta americana (Blattodea:Blattidae) toxicity of 17 different plant-based essential oil against, adults were investigated. Used oils Lavendula angustifola (Lamiaceae), Zingiber officinale (Zingiberaceae), Citrus bergamia (Rutaceae), Juniperus virginiana (Cupressaceae), Piper nigrum (Piperaceae), Curcuna longa Betula lenta (Betulaceae), Myristica fragranaceae (Myristica fragranaceae), com...

The eukaryotic 38-kD acidic ribosomal protein PO is localized to the stalk of the 60s ribosomal subunit, forming a pentameric complex with dimers of 13-kD acidic ribosomal proteins P1 and P2 (Rich and Steitz, 1987). P1 (P2) and PO are analogous to Escherichia coli ribosomal protein L7/L12, and L10, respectively, and are thought to have the same functions as their prokaryotic counterparts, i.e. ...

A series of novel 4-methylumbelliferone amide derivatives were designed, synthesized and characterized by ¹H NMR, 13C NMR and HR-ESI-MS. The structures of compounds 4bd and 4be (compounds named by authors) were further confirmed by X-ray single crystal diffraction. The acaricidal, herbicidal and antifungal activities of the synthesized compounds were assayed for their potential use as pesticide...

The tonoplast of isolated vacuoles from photoautotrophic suspension cells of Chenopodium rubrum L. was studied by means of the patch-clamp technique. In a symmetrical K(+) concentration of 46 mM, similar to in vivo conditions, the tonoplast displayed a membrane potential near zero and a linear current-voltage relationship with a mean slope of 1.0 S/m(2). ATP at 2 mM hyperpolarized the tonoplast...

Chenopodium ambrosioides conhecida como mastruço, é utilizado na medicina tradicional para tratamento de ascaridíase; controle artrópodes e pragas domésticas; inibição do desenvolvimento fungos solo insetos, lesões cutâneas alívio da dor barriga gripe. O objetivo presente trabalho constituiu avaliação teor extrativo óleo essencial L. cultivado no Horto Medicinal Universidade Paranaense (Umuaram...
