The essential oil was obtained by hydrodistillation and the identification and quantification of components were achieved with the use of GC-MS analysis. The antioxidant activity was evaluated by the method of sequestration of DPPH. Essential oils were used for study the cytotoxic front larvae of Artemia salina. In the evaluation of the antimicrobial activity of essential oils, we employed the ...

We report high signal-to-noise Spitzer Infrared Spectrograph spectra of a sample of 11 classical T Tauri stars. Molecular emission from rotational transitions of H2O and OH and rovibrational bands of simple organic molecules (CO2, HCN, C2H2) is common among the sources in the sample. The emission shows a range in both flux and line-to-continuum ratio for each molecule and in the flux ratios of ...

Climate changes and global warming are considered as very important challenges of sustainable development. Carbon sequestration is the easiest and cheapest way to reduce the greenhouse gases, especially carbon which constitutes the largest portion of them. In the present study, the potential of carbon sequestration in four plant species of Atriplex canescens, Haloxylon persicum, Artemisia siebe...

The effect of cortisone on the sequestration of (a) antibody-coated red cells and (b) incubated red cells was studied in rats. Cortisone administration inhibited the hepatic sequestration of red cells altered by non-immune as well as by immune injury. There was a latent period of 2 days between the institution of cortisone therapy and its first manifest effect on hepatic sequestration. The sple...

The paramagnetic microbead-based electrochemical binding assay was demonstrated for detecting two kinds of protein simultaneously. The principle of this assay is based on the sequestration electrochemistry. The protein binding electroactive magnetic microbeads which are conjugated with an electroactive compound and a ligand to bind specifically with a target protein were prepared. The avidin-bi...

Continuous exposure of cells to hormonal agonists often causes a rapid waning of the stimulated response. This desensitization effect has been extensively studied in the beta-adrenergic receptor system, and attributed largely to the rapid phosphorylation of the receptor by two kinases. Over a similar time frame (seconds to minutes), agonists also trigger a selective loss in the capacity of rece...

The cases of a mother and infant son are reported, both with a rare type of pulmonary sequestration where the arterial supply to the lung arises from the systemic circulation. This is a familial case of arterial sequestration. In both patients, the lung parenchyma was radiologically normal.

We report a case of a 60-year-old female who was known to have intralobar pulmonary sequestration and her only symptom was chronic cough. She had no history of infections and surgical resection led to complete resolution of her chronic cough.
