Effects of ferumoxytol on quantitative PET measurements in simultaneous PET/MR whole-body imaging: a pilot study in a baboon model.

EJNMMI physics

Borra RJ, Cho HS, Bowen SL, Attenberger U, Arabasz G, Catana C, Josephson L, Rosen BR, Guimaraes AR, Hooker JM.
PMID: 26501808
EJNMMI Phys. 2015 Dec;2(1):6. doi: 10.1186/s40658-015-0109-0. Epub 2015 Feb 26.

BACKGROUND: Simultaneous PET/MR imaging depends on MR-derived attenuation maps (mu-maps) for accurate attenuation correction of PET data. Currently, these maps are derived from gradient-echo-based MR sequences, which are sensitive to susceptibility changes. Iron oxide magnetic nanoparticles have been used...

Ethoxyzolamide repression of the low photorespiration state in two submersed angiosperms.

Planta

Salvucci ME, Bowes G.
PMID: 24264444
Planta. 1983 Jun;158(1):27-34. doi: 10.1007/BF00395399.

Net photosynthesis in the submersed angiosperms Myriophyllum spicatum L. and Hydrilla verticillata (L.f.) Royal was inhibited by 21% O2, but the degree of inhibition was greater for plants in the high than in the low photorespiratory state. Increasing the...

Exclusive Csp(3)-Csp(3) vs Csp(2)-Csp(3) Reductive Elimination from Pt(IV) Governed by Ligand Constraints.

Journal of the American Chemical Society

Bowes EG, Pal S, Love JA.
PMID: 26673642
J Am Chem Soc. 2015 Dec 30;137(51):16004-7. doi: 10.1021/jacs.5b10993. Epub 2015 Dec 16.

Selective reductive elimination of ethane (Csp(3)-Csp(3) RE) was observed following bromide abstraction and subsequent thermolysis of a Pt(IV) complex bearing both Csp(3)- and Csp(2)-hybridized hydrocarbyl ligands. Through a comparative experimental and theoretical study with two other Pt(IV) complexes featuring...

Cathelicidin suppresses colon cancer development by inhibition of cancer associated fibroblasts.

Clinical and experimental gastroenterology

Cheng M, Ho S, Yoo JH, Tran DH, Bakirtzi K, Su B, Tran DH, Kubota Y, Ichikawa R, Koon HW.
PMID: 25565877
Clin Exp Gastroenterol. 2014 Dec 17;8:13-29. doi: 10.2147/CEG.S70906. eCollection 2015.

BACKGROUND: Cathelicidin (LL-37 in humans and mCRAMP in mice) represents a family of endogenous antimicrobial and anti-inflammatory peptides. Cancer-associated fibroblasts can promote the proliferation of colon cancer cells and growth of colon cancer tumors.METHODS: We examined the role of...

A phase Ib multiple ascending dose study of the safety, tolerability, and central nervous system availability of AZD0530 (saracatinib) in Alzheimer's disease.

Alzheimer's research & therapy

Nygaard HB, Wagner AF, Bowen GS, Good SP, MacAvoy MG, Strittmatter KA, Kaufman AC, Rosenberg BJ, Sekine-Konno T, Varma P, Chen K, Koleske AJ, Reiman EM, Strittmatter SM, van Dyck CH.

INTRODUCTION: Despite significant progress, a disease-modifying therapy for Alzheimer's disease (AD) has not yet been developed. Recent findings implicate soluble oligomeric amyloid beta as the most relevant protein conformation in AD pathogenesis. We recently described a signaling cascade whereby...

Even the normal is abnormal: N-heterocyclic carbene C(2) binding to a phosphaalkene without breaking the P=C π-bond.

Chemical communications (Cambridge, England)

Majhi PK, Chow KC, Hsieh TH, Bowes EG, Schnakenburg G, Kennepohl P, Streubel R, Gates DP.
PMID: 26592925
Chem Commun (Camb). 2016 Jan 18;52(5):998-1001. doi: 10.1039/c5cc08181e.

The reaction of MesP=CPh2 with the least sterically demanding N-heterocyclic carbene (NHC = IMe) results in formation of the 'abnormal' (C(4)-substituted) 4-phosphino-NHC (1). In contrast, reaction with Me2IMe gives the unprecedented 'normal' C(2) adduct, Me2IMe → P(Mes)=CPh2 (2). Particularly...

The role of phosphoenolpyruvate carboxykinase in a marine macroalga with C4-like photosynthetic characteristics.

Proceedings of the National Academy of Sciences of the United States of America

Reiskind JB, Bowes G.
PMID: 11607173
Proc Natl Acad Sci U S A. 1991 Apr 01;88(7):2883-7. doi: 10.1073/pnas.88.7.2883.

Udotea flabellum is a marine, macroscopic green alga with C4-like photosynthetic characteristics, including little O2 inhibition of photosynthesis, a low CO2 compensation point, and minimal photorespiration; but it lacks anatomical features analogous to the Kranz compartmentation of C4 plants,...

Gas Exchange and C Allocation in Dunaliella salina Cells in Response to the N Source and CO2 Concentration Used for Growth.

Plant physiology

Giordano M, Bowes G.
PMID: 12223857
Plant Physiol. 1997 Nov;115(3):1049-1056. doi: 10.1104/pp.115.3.1049.

The halotolerant alga Dunaliella salina was cultured on 10 mM NH4+ or NO3- with air CO2 or 5% (v/v) CO2. Cells grown on NH4+ rather than NO3- were up to 17% larger in volume but had similar division rates....

Regulation and Localization of Key Enzymes during the Induction of Kranz-Less, C4-Type Photosynthesis in Hydrilla verticillata.

Plant physiology

Magnin NC, Cooley BA, Reiskind JB, Bowes G.
PMID: 12223888
Plant Physiol. 1997 Dec;115(4):1681-1689. doi: 10.1104/pp.115.4.1681.

Kranz-less, C4-type photosynthesis was induced in the submersed monocot Hydrilla verticillata (L.f.) Royle. During a 12-d induction period the CO2 compensation point and O2 inhibition of photosynthesis declined linearly. Phosphoenolpyruvate carboxylase (PEPC) activity increased 16-fold, with the major increase...

Comparison of the photosynthetic characteristics of three submersed aquatic plants.

Plant physiology

Light- and CO(2)-saturated photosynthetic rates of the submersed aquatic plants Hydrilla verticillata, Ceratophyllum demersum, and Myriophyllum spicatum were 50 to 60 mumol O(2)/mg Chl.hr at 30 C. At air levels of CO(2), the rates were less than 5% of...
