To examine the toxicity of cyclosiloxanes (CSs), the predominant low molecular weight cyclic silicones found in breast implants, we injected female CD-1 mice intraperitoneally with different doses of distillate (3.5-35 g/kg body weight) containing cyclosiloxane D3 (hexamethylcyclotrisiloxane; CS-D3), cyclosiloxane D4 (octamethylcyclotetrasiloxane; CS-D4), cyclosiloxane D5 (decamethylcyclopentas...

background  apnea is one of the most common problems in preterm neonates. this study aimed to evaluate the effectiveness of aromatherapy on the reduction of apnea, bradycardia, and pulse oximetry (spo2) in premature infants. materials and methods in a clinical trial study, 60 preterm neonates randomly divided in two groups and exposed to aromatherapy with rosa damascenes distillate or distilled...

12 Some guidelines to evaluate distillation columns, considering only basic 13 thermodynamic data and principles, are provided in this paper. The method allows a 14 first insight to the problem by simple calculations, without requiring column variables 15 to ensure rational use of energy and low environmental impact. The separation system is 16 approached by two complementary ways: minimum and ...

Mature skim milk cultures of Streptococcus lactis var. maltigenes were steam distilled at low temperature under reduced pressure. Ethyl ether extracts were prepared from the distillates and analyzed by gas-liquid chromatography and mass spectrometry. Twenty of 31 components detected in the culture distillates were identified positively and 11 tentatively, whereas 10 of 19 components detected in...

This review of holoprosencephaly provides a mythologic and teratologic distillate of the subject under the following headings: Babylonian tablets; Greek mythology; pictures from the 16th through the 20th Centuries; 19th Century teratology; history of more modern concepts and their terminologies; and ocean-going ships named "Cyclops."

The steam-distilled fraction of the aerial parts of Erigeron speciosus (Lindl) DC was tested for activity against strawberry plant pathogenic fungi Botrytis cinerea Pers ex Fr, Colletotrichum acutatum Simmonds, C fragariae Brooks, C gloeosporioides (Penz) Penz & Sacc, and the intermediate host snail Planobdella trivolvis that harbors the trematode, Bolbophorus confusus, that infests and causes ...

Feasibility of batch extractive distillation in rectifying column with a middle boiling entrainer is theoretically and experimentally studied. These processes are preferable when the entrainer is already present in the mixture to be separated. Separation of methyl acetate and cyclohexane (forming minimum boiling azeotrope) using carbon tetrachloride, and separation of chloroform and ethyl aceta...
