Determining the location and nearest neighbours of aluminium in zeolites with atom probe tomography.

Nature communications

Perea DE, Arslan I, Liu J, Ristanović Z, Kovarik L, Arey BW, Lercher JA, Bare SR, Weckhuysen BM.
PMID: 26133270
Nat Commun. 2015 Jul 02;6:7589. doi: 10.1038/ncomms8589.

Zeolite catalysis is determined by a combination of pore architecture and Brønsted acidity. As Brønsted acid sites are formed by the substitution of AlO4 for SiO4 tetrahedra, it is of utmost importance to have information on the number as...

INTRODUCTION: Spindle cell carcinoma of the head and neck is a rare entity and the evidence of optimal management is lacking. The objective of our study was to report the treatment and outcomes of 15 patients treated in a...

Iatrogenic T-Cell Lymphoma with Associated Hemophagocytic Lymphohistiocyotsis in a Patient with Long-Standing Rheumatoid Arthritis.

Case reports in hematology

Patients with rheumatoid arthritis are at increased risk of hematological malignancies, especially when exposed to immunosuppressive therapy. The mechanisms of lymphomagenesis remain poorly understood but factors implicated include high disease activity, exposure to antitumoral necrosis factor medications, and Epstein-Barr...

A genetic appraisal of a new synthetic Nicotiana tabacum (Solanaceae) and the Kostoff synthetic tobacco.

American journal of botany

Lim KY, Souckova-Skalicka K, Sarasan V, Clarkson JJ, Chase MW, Kovarik A, Leitch AR.

Am J Bot. 2006 Jun;93(6):875-83. doi: 10.3732/ajb.93.6.875.

Polyploids have significantly influenced angiosperm evolution. Understanding the genetic consequences of polyploidy is advanced by studies on synthetic allopolyploids that mimic natural species. In Nicotiana, Burk (1973) and Kostoff (1938) generated synthetic tobacco (N. tabacum) using the parents ♀N....

Maintenance therapy with trastuzumab in her2 positive metastatic parotid ductal adenocarcinoma.

Salivary ductal carcinomas (SDCs) are extremely rare and aggressive malignancies, accounting for approximately 6% of all salivary gland malignancies. One distinct feature is their resemblance to ductal carcinomas of breast. A significant percentage of SDCs overexpress Her2 and the...

Oncogenic viruses associated with vulva cancer in HIV-1 patients in Botswana.
