Thickness measurements of lacey carbon films.

Journal of microscopy

Karlsson G.
PMID: 11555151
J Microsc. 2001 Sep;203:326-8. doi: 10.1046/j.1365-2818.2001.00930.x.

Lacey carbon filmed grids interact differently with liquid samples during plunging and subsequent studies in cryo-TEM depending on type and manufacture. One important parameter is the thickness of the film, which is investigated here by ultrathin sectioning. The film...

Phase segregation in AlInP shells on GaAs nanowires.

Nano letters

Sköld N, Wagner JB, Karlsson G, Hernán T, Seifert W, Pistol ME, Samuelson L.
PMID: 17163698
Nano Lett. 2006 Dec;6(12):2743-7. doi: 10.1021/nl061692d.

We have studied morphology and phase segregation of AlInP shells on GaAs nanowires. Photoluminescence measurements on single core-shell nanowires indicated variations in the shell composition, and phase segregation was confirmed by cross-sectional scanning transmission electron microscopy on 30 nm...

[Deep vein thrombosis incidence at Akureyri Hospital, Iceland 1975-1990. Long term prognosis.].

Laeknabladid

Karlsson G, Riba P, Thoroddsson I, Gudbjornsson B.
PMID: 17018905
Laeknabladid. 2000 Jan;86(1):19-24.

OBJECTIVE: To evaluate the incidence of deep vein thrombosis (DVT) in a rural area of Iceland and the prevalence of post thrombotic syndrome (PTS) in patients with history of DVT.MATERIAL AND METHODS: A retrospective study where all phlebographies (n=177)...

TEM-tomography of FAU-zeolite crystals containing Pt-clusters.

Ultramicroscopy

Bovin JO, Alfredsson V, Karlsson G, Carlsson A, Blum Z, Terasaki O.
PMID: 22666910
Ultramicroscopy. 1996 Mar;62(4):277-81. doi: 10.1016/0304-3991(96)00002-2.

A method for preparing ultrathin sections (- 20 nm) of inorganic solids has been developed using ultramicrotomy of resin-embedded crystal fragments. Undamaged crystals, oriented along a crystallographic direction, could be imaged with transmission electron microscopy (TEM) at a resolution...

Oxytocin-Monolayer-Based Impedimetric Biosensor for Zinc and Copper Ions.

Tadi KK, Alshanski I, Mervinetsky E, Marx G, Petrou P, Dimitrios KM, Gilon C, Hurevich M, Yitzchaik S.
PMID: 29302631
ACS Omega. 2017 Dec 31;2(12):8770-8778. doi: 10.1021/acsomega.7b01404. Epub 2017 Dec 08.

Zinc and copper are essential metal ions for numerous biological processes. Their levels are tightly maintained in all body organs. Impairment of the Zn

Anatomical and functional visual network patterns in progressive multiple sclerosis.

Human brain mapping

Backner Y, Zamir S, Petrou P, Paul F, Karussis D, Levin N.
PMID: 34931352
Hum Brain Mapp. 2021 Dec 20; doi: 10.1002/hbm.25744. Epub 2021 Dec 20.

The gradual accrual of disability over time in progressive multiple sclerosis is believed to be driven by widespread degeneration. Yet another facet of the problem may reside in the loss of the brain's ability to adapt to the damage...

Cryo-TEM Snapshots of Ferritin Adsorbed on Small Zeolite Crystals.

Angewandte Chemie (International ed. in English)

Klint D, Karlsson G, Bovin JO.
PMID: 10508338
Angew Chem Int Ed Engl. 1999 Sep;38(17):2560-2562.

The adsorption of macromolecules on zeolite crystal surfaces has been investigated by cryo transmission electron microscopy (TEM) of frozen hydrates. It was determined that ferritin shows different adsorption behavior on NaY (TEM image on the right) and USY zeolites...

Synergistic neuroprotective effects of Fingolimod and mesenchymal stem cells (MSC) in experimental autoimmune encephalomyelitis.

Immunology letters

Kassis I, Ben-Zwi M, Petrou P, Halimi M, Karussis D.
PMID: 33676976
Immunol Lett. 2021 May;233:11-19. doi: 10.1016/j.imlet.2021.03.003. Epub 2021 Mar 04.

Fingolimod (Gilenya™) is an effective oral medication approved for relapsing-remitting multiple sclerosis (MS), albeit less effective in chronic disease. Its main mechanism of action is through peripheral immunomodulation but neuroprotective effects may also be involved. Mesenchymal stem cells (MSC)...

Mixing behaviour of a symmetrical single-chain bolaamphiphile with phospholipids.

Soft matter

Meister A, Köhler K, Drescher S, Dobner B, Karlsson G, Edwards K, Hause G, Blume A.
PMID: 32900052
Soft Matter. 2007 Jul 17;3(8):1025-1031. doi: 10.1039/b703152a.

The mixing behavior of the symmetric long-chain bolaamphiphile dotriacontane-1,1'-diyl-bis-[2-(trimethylammonio)ethylphosphate] (PC-C32-PC) with conventional phospholipids (DPPC, DMPC, and POPC) was investigated by differential scanning calorimetry and transmission electron microscopy. PC-C32-PC by itself forms nanofibers at room temperature, which convert to micellar...

Usage of nonporous polymeric particles for reversed-phase high-performance liquid chromatography of oxidized and deamidated forms of recombinant human growth hormone.
