Impact of intracytoplasmic sperm injection on the activation and fertilization process of oocytes.

Reproductive biomedicine online

Ludwig M, Schröder AK, Diedrich K.
PMID: 12513861
Reprod Biomed Online. 2001;3(3):230-240. doi: 10.1016/s1472-6483(10)62042-1.

Intracytoplasmic sperm injection (ICSI) is used worldwide to treat preferentially severe cases of male factor infertility. In this review, data regarding the processes of oocyte activation and fertilization in non-assisted conception, conventional IVF and ICSI are discussed. The second...

Identification of lignans by liquid chromatography-electrospray ionization ion-trap mass spectrometry.

Journal of mass spectrometry : JMS

Eklund PC, Backman MJ, Kronberg LA, Smeds AI, Sjöholm RE.
PMID: 17729382
J Mass Spectrom. 2008 Jan;43(1):97-107. doi: 10.1002/jms.1276.

The fragmentation pattern of 30 compounds belonging to different classes of the lignan family was studied by liquid chromatography-electrospray ionization ion-trap mass spectrometry. On the basis of the observed fragmentation patterns, identification of different types of lignans was achieved....

Single-crystalline platinum nanosheets from nonionic surfactant 2-D self-assemblies at solid/aqueous solution interfaces.

Langmuir : the ACS journal of surfaces and colloids

Kawasaki H, Uota M, Yoshimura T, Fujikawa D, Sakai G, Annaka M, Kijima T.
PMID: 16285827
Langmuir. 2005 Nov 22;21(24):11468-73. doi: 10.1021/la051247i.

Single-crystalline platinum nanosheets have been prepared via a new methodology based on the chemical reduction of a platinum salt (H2PtCl6) with hydrazine at a graphite/solution interface, using polyoxyethylene (20) sorbitan monostearate (Tween 60) based self-assembly (hemicylindrical micelle) templates. The...

Dirubidium aquapentachlorochromate(III) and dicaesium aquapentachlorochromate(III).

Acta crystallographica. Section C, Crystal structure communications

Eriksson AK, Casari BM, Langer V.
PMID: 15071195
Acta Crystallogr C. 2004 Apr;60:i40-2. doi: 10.1107/S0108270104002987. Epub 2004 Mar 20.

The structures of the two novel title compounds, Rb(2)[CrCl(5)(H(2)O)], (I), and Cs(2)[CrCl(5)(H(2)O)], (II), have been determined by single-crystal X-ray diffraction. Compounds (I) and (II) crystallize with Pnma and Cmcm symmetry, respectively. In (I), the Cr, three Cl and water...

Reduction of the HIV-1 reservoir in resting CD4+ T-lymphocytes by high dosage intravenous immunoglobulin treatment: a proof-of-concept study.

AIDS research and therapy

Lindkvist A, Edén A, Norström MM, Gonzalez VD, Nilsson S, Svennerholm B, Karlsson AC, Sandberg JK, Sönnerborg A, Gisslén M.
PMID: 19570221
AIDS Res Ther. 2009 Jul 01;6:15. doi: 10.1186/1742-6405-6-15.

BACKGROUND: The latency of HIV-1 in resting CD4+ T-lymphocytes constitutes a major obstacle for the eradication of virus in patients on antiretroviral therapy (ART). As yet, no approach to reduce this viral reservoir has proven effective.METHODS: Nine subjects on...

Effect of dietary intervention on serum lignan levels in pregnant women - a controlled trial.

Reproductive health

Luoto R, Kharazmi E, Saarinen NM, Smeds AI, Mäkelä S, Fallah M, Raitanen J, Hilakivi-Clarke L.
PMID: 20932282
Reprod Health. 2010 Oct 08;7:26. doi: 10.1186/1742-4755-7-26.

BACKGROUND: Mother's diet during pregnancy is important, since plant lignans and their metabolites, converted by the intestinal microflora to enterolignans, are proposed to possess multiple health benefits. Aim of our study was to investigate whether a dietary intervention affects...

Changing the volume of a giant macrocycle: the swelling of the macrocycle with organic solvents.

Organic & biomolecular chemistry

Harano A, Tanaka M, Nakagaki T, Annaka M, Ideta K, Goto K, Shinmyozu T.
PMID: 21483979
Org Biomol Chem. 2011 May 21;9(10):3611-4. doi: 10.1039/c1ob05272a. Epub 2011 Apr 11.

The novel tetrahedral macrocycles 1a-1c have been synthesized. Macrocycles 1a and 1c were revealed to have the property to increase in volume in solution by complexation between the macrocycle and the solvent molecules.

Flaxseed ingestion alters ratio of enterolactone enantiomers in human serum.

Journal of nutrition and metabolism

Saarinen NM, Smeds AI, Peñalvo JL, Nurmi T, Adlercreutz H, Mäkelä S.
