Retinal Vascular Signs as Screening and Prognostic Factors for Chronic Kidney Disease: A Systematic Review and Meta-Analysis of Current Evidence.

Journal of personalized medicine

Aronov M, Allon R, Stave D, Belkin M, Margalit E, Fabian ID, Rosenzweig B.
PMID: 34357132
J Pers Med. 2021 Jul 15;11(7). doi: 10.3390/jpm11070665.

BACKGROUND: The substantial burden of kidney disease fosters interest in new ways of screening for early disease diagnosis, especially by non-invasive imaging. Increasing evidence for an association between retinal microvascular signs and kidney disease prompted us to investigate the...

Indian J Urol. 2016 Jul-Sep;32(3):232-7. doi: 10.4103/0970-1591.185104.

INTRODUCTION: Clavien-Dindo classification system is used for grading complications of various oncological, renal, and endourological procedures. We applied this system for grading the severity of perioperative complications in patients undergoing transurethral resection of bladder tumor (TURBT) and identify parameters...

Loss mechanisms in dielectric optical interference devices.

Applied optics

Arnon O.
PMID: 20168888
Appl Opt. 1977 Aug 01;16(8):2147-51. doi: 10.1364/AO.16.002147.

Residual absorption and scattering are loss mechanisms that degrade the performance of all thin films optical devices. By analogy to residual absorption, expressions are derived to evaluate losses due to surface and bulk scattering in dielectric multilayers. Based on...

Body fat and dairy product intake in lactase persistent and non-persistent children and adolescents.

Food & nutrition research

Almon R, Patterson E, Nilsson TK, Engfeldt P, Sjöström M.
PMID: 20585563
Food Nutr Res. 2010 Jun 16;54. doi: 10.3402/fnr.v54i0.5141.

BACKGROUND: Lactase non-persistent (LNP) individuals may be lactose intolerant and therefore on a more restricted diet concerning milk and milk products compared to lactase persistent (LP) individuals. This may have an impact on body fat mass.OBJECTIVE: This study examines...

Synthesis and catalytic properties of Au-Pd nanoflowers.

ACS nano

Xu J, Wilson AR, Rathmell AR, Howe J, Chi M, Wiley BJ.
PMID: 21761821
ACS Nano. 2011 Aug 23;5(8):6119-27. doi: 10.1021/nn201161m. Epub 2011 Jul 15.

Reduction of Pd ions by hydroquinone in the presence of gold nanoparticles and polyvinylpyrrolidone resulted in the formation of nanoflowers with a Au core and Pd petals. Addition of HCl to the synthesis halted the reduction by hydroquinone and...

Elucidating the Complex Interactions between Stress and Epileptogenic Pathways.

Cardiovascular psychiatry and neurology

Friedman AR, Cacheaux LP, Ivens S, Kaufer D.
PMID: 21547249
Cardiovasc Psychiatry Neurol. 2011;2011:461263. doi: 10.1155/2011/461263. Epub 2011 Mar 20.

Clinical and experimental data suggest that stress contributes to the pathology of epilepsy. We review mechanisms by which stress, primarily via stress hormones, may exacerbate epilepsy, focusing on the intersection between stress-induced pathways and the progression of pathological events...
