Crystal structures are reported for N-(4-methoxyphenyl)piperazine (MeOPP), (I), and for its 3,5-dinitrobenzoate, 2,4,6-trinitrophenolate (picrate) and 4-aminobenzoate salts, (II)–(IV), the last of which crystallizes as a monohydrate. In MeOPP, C11H16N2O, (I), the 4-methoxyphenyl group is nearly planar and it occupies an equatorial site on...

Researchers are finally uncovering the truth about glycans — the sugar-based chains that coat cells and decorate many proteins.
Energy production and environmental pollution are the two major problems the world is facing today. The depletion of fossil fuels and the emission of harmful gases into the atmosphere lead the research on clean and renewable energy sources. In this context, hydrogen is considered as an ideal fuel for meeting the global energy needs. However, at pre...
Chalcones of type 4-XC6H4C(O)CH=CHC6H4(OCH2CCH)-4, where X = Cl, Br or MeO, have been converted to the corresponding 4,5-dihydropyrazole-1-carbothioamides using a cyclocondensation reaction with thiosemicarbazide. The chalcones 1-(4-chlorophenyl)-3-[4-(prop-2-ynyloxy)phenyl]prop-2-en-1-one, C18H13ClO2, (I), and 1-(4-bromophenyl)-3-[4-(p...
Precursors of pancreatic cancer arise in the ductal epithelium; markers exfoliated into pancreatic juice might be used to detect high-grade dysplasia (HGD) and cancer. Specific methylated DNA sequences in pancreatic tissue have been associated with adenocarcinoma. We analyzed these methylated DNA markers (MDMs) in pancreatic juice samples from pati...

We compared first-year cumulative grade point average and a composite score on part I of the National Board of Chiropractic Examiners (NBCE) exam for first-year alternative admission track program (AATP) students who did and did not take three specific undergraduate courses: general chemistry, organic chemistry, and anatomy and physiology. All AATP...
The all-sided information provided by greenhouse gas experts is disturbing. Future ocean level and atmosphere temperature raises are assigned to an increase of "greenhouse effect" due to the surplus of carbon dioxide (CO2) of anthropogenic origin. Reducing the fossil sources of CO2 is therefore the recommended solution. However, the related dogma i...

Calculus bovis (C. bovis), a widespread known traditional animal drug in China and Japan, has been widely used for a long time to treat various diseases, including high fever, convulsion and stroke. The aim of the present paper is to comprehensively review knowledge about C. bovis in terms of traditional usages, origin, chemical constituents, pharm...
