Guidelines for quality control of PET/CT scans in a multicenter clinical study.

EJNMMI physics

Hristova I, Boellaard R, Galette P, Shankar LK, Liu Y, Stroobants S, Hoekstra OS, Oyen WJG.
PMID: 28924696
EJNMMI Phys. 2017 Sep 18;4(1):23. doi: 10.1186/s40658-017-0190-7.

To date, there is no published detailed checklist with parameters referencing the DICOM tag information with respect to the quality control (QC) of PET/CT scans. The aims of these guidelines are to provide the know-how for effectively controlling the...

CONCLUSIONS: In summary, in central chondrosarcoma

Microspore culture of Hordeum vulgare L.: the influence of density and osmolality.

Plant cell reports

Hoekstra S, van Zijderveld MH, Heidekamp F, van der Mark F.
PMID: 24201960
Plant Cell Rep. 1993 Oct;12(12):661-5. doi: 10.1007/BF00233415.

Donor plants of Hordeum vulgare L. cv. Igri were grown in a conditioned environment to minimise fluctuations in the composition of the microspore population. After isolation different types of microspores were identified within each population, amongst others an embryogenic...

Tuning the Lattice Parameter of InxZnyP for Highly Luminescent Lattice-Matched Core/Shell Quantum Dots.

ACS nano

Pietra F, De Trizio L, Hoekstra AW, Renaud N, Prato M, Grozema FC, Baesjou PJ, Koole R, Manna L, Houtepen AJ.
PMID: 27065247
ACS Nano. 2016 Apr 26;10(4):4754-62. doi: 10.1021/acsnano.6b01266. Epub 2016 Apr 14.

Colloidal quantum dots (QDs) show great promise as LED phosphors due to their tunable narrow-band emission and ability to produce high-quality white light. Currently, the most suitable QDs for lighting applications are based on cadmium, which presents a toxicity...

Convergence of the discrete dipole approximation. I. Theoretical analysis: erratum.

Journal of the Optical Society of America. A, Optics, image science, and vision

PMID: 26831394
J Opt Soc Am A Opt Image Sci Vis. 2015 Dec 01;32(12):2407-8. doi: 10.1364/JOSAA.32.002407.

We report and address the errors in the analysis of the weighted discretization in Section 2.F of our published paper [J. Opt. Soc. Am. A23, 2578 (2006)JOAOD61084-752910.1364/JOSAA.23.002578].

Plasma IL-25 is elevated in a subgroup of patients with clinical reactivity to peanut.

Clinical and translational allergy

Aalberse JA, van Thuijl AO, Meijer Y, de Jager W, van der Palen-Merkus T, Sprikkelman AB, Hoekstra MO, Prakken BJ, van Wijk F.
PMID: 24295226
Clin Transl Allergy. 2013 Dec 02;3(1):40. doi: 10.1186/2045-7022-3-40.

BACKGROUND: One of the IL-17 family members, IL-25, has been implicated with the initiation and amplification of Th2 responses in animal models and has been associated with airway hyper-reactivity. The involvement of IL-25 and also IL-17 in food allergic...

Mass balance of trichloroacetic acid in the soil top layer.

Chemosphere

Hoekstra EJ, de Leer EW, Brinkman UA.
PMID: 10901673
Chemosphere. 1999 Feb;38(3):551-63. doi: 10.1016/s0045-6535(98)00206-9.

Since the ban on the use of trichloroacetic acid (TCAA) as a herbicide in several countries, TCAA is still found ubiquitously in the environment. The presence of TCAA nowadays is suggested to originate mainly from the atmospheric degradation of...

Surgical Prevention and Treatment of Late Normal Tissue Injury.

Seminars in radiation oncology

Schraffordt Koops H, Hoekstra HJ.
PMID: 10717098
Semin Radiat Oncol. 1994 Apr;4(2):119-122. doi: 10.1053/SRAO00400119.

There is a definite increase in combined-modality treatment of malignancies. Surgery, radiation therapy and/or chemotherapy often are combined. A disadvantage is the increased risk for short- and long-term complications, especially radiation-induced damage to normal healthy tissue such as intestine...

Pulse advancement and delay in an integrated-optical two-port ring-resonator circuit: direct experimental observations.

Optics letters

Uranus HP, Zhuang L, Roeloffzen CG, Hoekstra HJ.
PMID: 17767325
Opt Lett. 2007 Sep 01;32(17):2620-2. doi: 10.1364/ol.32.002620.

We report experimental observations of the negative-group-velocity (v(g)) phenomenon in an integrated-optical two-port ring-resonator circuit. We demonstrate that when the v(g) is negative, the (main) peak of output pulse appears earlier than the peak of a reference pulse, while...

Desiccation Tolerance of Papaver dubium L. Pollen during Its Development in the Anther: Possible Role of Phospholipid Composition and Sucrose Content.

Plant physiology

Hoekstra FA, van Roekel T.
PMID: 16666359
Plant Physiol. 1988 Nov;88(3):626-32. doi: 10.1104/pp.88.3.626.

Developing pollen of Papaver dubium L. becomes functional and desiccation tolerant at approximately 2 to 1 days prior to anthesis, coincident with degradation of starch and a doubling of the amount of sucrose, the primary soluble carbohydrate present. When...
