Dear Editor: Pergularia daemia Forsk (Asclepiadaceae) is a perennial twining herb commonly known as veliparuthi in Tamil. The plant has anthelmintic, laxative, antidiabetic, hepatoprotective and anti-inflammatory activities [1] . The pharmacological properties of this plant come from bioactive phytochemicals such as alkaloids, triterpenes, saponins and flavonoids. Phytochemically, the plant has...

Diacylglycerols composed of one saturated and one unsaturated chain make up the hydrophobic core of many biological membranes. We report here the first crystalline structure of such a mixed chain diacylglycerol. The mixed chain diacylglycerol, 1-stearoyl-3-oleyl-glycerol ( 1,3-SODG) was produced by solution isomerization of 1-stearoyl-2-oleylsn-glycerol. 1.3-SODG was isolated by flash chromatog...

ingolipids (GSLs) from echinoderms, a series of studies on the isolation and structural elucidation of the GSLs from sea cucumber species have been performed in our laboratory. In the study of the GSLs of the sea cucumber Holothuria pervicax (Torafunamako in Japanese), we reported the isolation and structure of four new ganglioside molecular species. Continuing the preceding studies, the isolat...

White oils or waxes [mineral hydrocarbons (MHCs)] with substantial levels of saturated hydrocarbons in the range of C18 to C32 have produced hepatic microgranulomas and lymph node microgranulomas (also referred to as histiocytosis) after repeated administration to female Fischer-344 (F-344) rats. Female SpragueDawley (S-D) rats are less sensitive to these MHC-induced hepatic and lymph node effe...

3D printing strategies provide flexible solutions for complex and programmable thermal management versatile material integration. 3D-printed composite phase change materials (PCMs) can overcome shape limitations optimize structures to construct object designs effective management. Recently in Matter, Emily B. Pentzer et al. creatively proposed a facile strategy print PCM-filled inks with excell...

Spiro ring systems have two or more rings linked by one common atom. Several different methods are used to name such systems. Rules A-41, A-43, B-b and B-12 (Nomenclature of Organic Chemistry, 1979) describe the basics of how to name these compounds. The alternative methods in rules A-42 and B-i 1 are abandoned. This document describes the nomenclature in greater detail and extends it to cover ...

Bioremediation is now the best successful initiative to mitigate and to recover sites contaminated with hydrocarbons and has been the preferred process for clean-up contamination around the oceans of the world. The advantages of marine microorganisms in the removal of petroleum hydrocarbons, exemplifies the eco-sustainable bioremediation that can be achieved in sensitive marine environments and...
