Objective: To determine the validity of adjusted indirect comparisons by using data from published meta-analyses of randomised trials. Design: Direct comparison of different …

Laser damage mechanisms in conductive widegap semiconductor films.

Optics express

Yoo JH, Menor MG, Adams JJ, Raman RN, Lee JR, Olson TY, Shen N, Suh J, Demos SG, Bude J, Elhadj S.
PMID: 27505731
Opt Express. 2016 Aug 08;24(16):17616-34. doi: 10.1364/OE.24.017616.

Laser damage mechanisms of two conductive wide-bandgap semiconductor films - indium tin oxide (ITO) and silicon doped GaN (Si:GaN) were studied via microscopy, spectroscopy, photoluminescence (PL), and elemental analysis. Nanosecond laser pulse exposures with a laser photon energy (1.03...

Multidisciplinary Approach to Hepatic Metastases of Intracranial Hemangiopericytoma: A Case Report and Review of the Literature.

Case reports in oncological medicine

Manatakis DK, Delis SG, Ptohis N, Korkolopoulou P, Dervenis C.

Case Rep Oncol Med. 2015;2015:214306. doi: 10.1155/2015/214306. Epub 2015 May 18.

Hemangiopericytoma is a rare primary tumor originating from Zimmerman's pericytes, with significant metastatic potential. Hepatic metastatic disease requires an aggressive approach by a multidisciplinary team of dedicated oncology specialists, to prolong survival in selected patients. We report on a...

GENOTYPIC AND ENVIRONMENTAL COMPONENTS OF VARIATION IN GROWTH AND REPRODUCTION OF FISH HEMICLONES (POECILIOPSIS: POECILIIDAE).

Evolution; international journal of organic evolution

Wetherington JD, Weeks SC, Kotora KE, Vrijenhoek RC.
PMID: 28568401
Evolution. 1989 May;43(3):635-645. doi: 10.1111/j.1558-5646.1989.tb04258.x.

The frozen-niche-variation model was proposed to account for the coexistence of genetically related clones in naturally occurring unisexual populations. This model is based on two assumptions: 1) ecologically different clones have multiple independent origins from sexual ancestors; and 2)...

An overview of systematic review.

Systematic review is an invaluable tool for the practicing clinician. A well-designed systematic review represents the latest and most complete information available on a particular topic or intervention. This article highlights the key elements of systematic review, what it...

Mechanisms of surface contamination in fused silica by means of laser-induced electrostatic effects.

Optics letters

Demos SG, Carr CW, Cross DA.
PMID: 28957305
Opt Lett. 2017 Jul 01;42(13):2643-2646. doi: 10.1364/OL.42.002643.

We demonstrate that fused-silica samples exposed to nanosecond laser pulses at 355 nm and 1064 nm develop long-lived electrostatic charges on their surfaces. These charges extend well beyond the area exposed to the laser beam. The results suggest this...

BACKGROUND: In HIV infection, lymphoid tissue is disrupted by fibrosis. Angiotensin converting enzyme inhibitors have anti-fibrotic properties. We completed a pilot study to assess whether the addition of lisinopril to antiretroviral therapy (ART) reverses fibrosis of gut tissue, and...

A Second-Order Longitudinal Model Of Ability Structure.

Olsson and Bergman (1977) presented a structural equation model for the development of intellectual abilities between the ages of 10 and 13. Their model proposed four correlated factors, each of which was stable over time. They also found that...

Laser photogrammetry improves size and demographic estimates for whale sharks.

Whale sharks Rhincodon typus are globally threatened, but a lack of biological and demographic information hampers an accurate assessment of their vulnerability to further decline or capacity to recover. We used laser photogrammetry at two aggregation sites to obtain...
