PMID: 26389091
CMAJ Open. 2015 Apr 02;3(2):E140-8. doi: 10.9778/cmajo.20140101. eCollection 2015.

BACKGROUND: Suicide rates have been reported at elevated levels among people living with HIV/AIDS. We sought to characterize longitudinal suicide rates among people living with HIV/AIDS who are accessing free highly active antiretroviral treatment (HAART) in British Columbia and...

Prevalence of hypertension and noise-induced hearing loss in Chinese coal miners.

Journal of thoracic disease

Liu J, Xu M, Ding L, Zhang H, Pan L, Liu Q, Ding E, Zhao Q, Wang B, Han L, Yang D, Zhu B.
PMID: 27076937
J Thorac Dis. 2016 Mar;8(3):422-9. doi: 10.21037/jtd.2016.02.59.

BACKGROUND: Owing to inconsistent epidemiologic evidence and the presence of confounding factors, the relation between occupational noise exposure and hypertension still remained unclear. We aimed to assess whether Chinese coal miners were at risk of developing hypertension and noise...

Evaluation of 4 Outcomes Measures in Microtia Treatment: Exposures, Infections, Aesthetics, and Psychosocial Ramifications.

Plastic and reconstructive surgery. Global open

Mandelbaum RS, Volpicelli EJ, Martins DB, Park SH, Dubina E, Ishiyama A, Bradley JP, Lee JC.
PMID: 29062641
Plast Reconstr Surg Glob Open. 2017 Sep 20;5(9):e1460. doi: 10.1097/GOX.0000000000001460. eCollection 2017 Sep.

BACKGROUND: In craniofacial microsomia, microtia and canal atresia pose formidable reconstructive challenges. We review our institutional experience in treating microtia and atresia to identify variables associated with 4 outcomes measures: complications, surgical revisions, aesthetic outcomes, and psychosocial function.METHODS: Craniofacial...

Realizing a finite array of dipole sources with high acoustic transmission directivity at low frequency.

The Journal of the Acoustical Society of America

Ding E, Mao Y, Liu X.
PMID: 28372129
J Acoust Soc Am. 2017 Mar;141(3):1936. doi: 10.1121/1.4978440.

A finite array of dipole sources is used to enhance the directivity and radiation gains of sound. This letter demonstrates that this idea can be realized as several sub-wavelength slits in a plate with periodic Helmholtz resonators. Moreover, the...

Purification and degradation of ribulose bisphosphate carboxylase from soybean leaves.

Plant physiology

Paech C, Dybing CD.
PMID: 16664815
Plant Physiol. 1986 May;81(1):97-102. doi: 10.1104/pp.81.1.97.

A rapid method is described for the preparation of up to 500 milligrams of pure ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBP carboxylase) from 250 grams of field-grown soybean leaves. Leaves were extracted in 20 millimolar phosphate (pH 6.9) at 4 degrees C,...

Biochemical characterization of soybean ovary growth from anthesis to abscission of aborting ovaries.

Plant physiology

Dybing CD, Ghiasi H, Paech C.
PMID: 16664945
Plant Physiol. 1986 Aug;81(4):1069-74. doi: 10.1104/pp.81.4.1069.

Soybean (Glycine max [L.] Merr.) ovary growth was measured from anthesis to 6 days after anthesis (DAA) to establish a timetable of biochemical events that might be useful in identifying processes that initiate abscission. Two procedures were developed to...

Preparation of novel silver-gold bimetallic nanostructures by seeding with silver nanoplates and application in surface-enhanced Raman scattering.

Journal of colloid and interface science

Zou X, Ying E, Dong S.
PMID: 17140593
J Colloid Interface Sci. 2007 Feb 15;306(2):307-15. doi: 10.1016/j.jcis.2006.10.084. Epub 2006 Nov 07.

Novel silver-gold bimetallic nanostructures were prepared by seeding with silver nanoplates in the absence of any surfactants. During the synthesis process, it was found that the frameworks of silver nanoplates were normally kept though the basal plane of silver...

Influence of cholecystokinin on the synaptosomal dopamine uptake in the nucleus accumbens of rats.

Neurochemistry international

Hetey L, Döring E, Penke B.
PMID: 20501125
Neurochem Int. 1987;10(4):525-8. doi: 10.1016/0197-0186(87)90079-9.

The influence of the sulfated cholecystokinin octapeptide (CCK-8S) on the synaptosomal high-affinity [(3)H]dopamine (DA) uptake was investigated in the medial and lateral part of nucleus accumbens in rats. CCK-8S induced a concentration-dependent biphasic inhibition of [(3)H]-DA uptake in both...

Dual transmission filters for enhanced energy in mode-locked fiber lasers.

Optics express

Li F, Ding E, Kutz JN, Wai PK.

Opt Express. 2011 Nov 07;19(23):23408-19. doi: 10.1364/OE.19.023408.

We theoretically demonstrate that in a laser cavity mode-locked by a set of waveplates and passive polarizer, the energy performance can be increased by incorporating a second set of waveplates and polarizer in the cavity. The two nonlinear transmission...

Seed-mediated synthesis of branched gold nanoparticles with the assistance of citrate and their surface-enhanced Raman scattering properties.
