Scientific reports

Lacava C, Stankovic S, Khokhar AZ, Bucio TD, Gardes FY, Reed GT, Richardson DJ, Petropoulos P.
PMID: 28154419
Sci Rep. 2017 Feb 02;7(1):22. doi: 10.1038/s41598-017-00062-6.

Nonlinear silicon photonic devices have attracted considerable attention thanks to their ability to show large third-order nonlinear effects at moderate power levels allowing for all-optical signal processing functionalities in miniaturized components. Although significant efforts have been made and many...

Pediatr Transplant. 2021 Oct 08;e14157. doi: 10.1111/petr.14157. Epub 2021 Oct 08.

BACKGROUND: Short telomere syndrome (STS) in children may result in phenotypically heterogenous clinical spectrum ranging from completely asymptomatic to typical dyskeratosis congenita (DC). Patients with this cancer predisposition syndrome may have multiple organ dysfunctions including pulmonary fibrosis, liver cirrhosis,...

Insulin resistance limits corneal nerve regeneration in patients with type 2 diabetes undergoing intensive glycemic control.

Journal of diabetes investigation

AIMS/INTRODUCTION: This study aimed to investigate whether insulin resistance (IR) in individuals with type 2 diabetes undergoing intensive glycemic control determines the extent of improvement in neuropathy.MATERIALS AND METHODS: This was an exploratory substudy of an open-label, randomized controlled...

Corneal nerve loss as a surrogate marker for poor pial collaterals in patients with acute ischemic stroke.

Scientific reports

Khan A, Menon A, Akhtar N, Kamran S, Muhammad A, Ponirakis G, Gad H, Petropoulos IN, Wadiwala F, Babu B, Narangoli AM, Bermejo PG, Al Hamad H, Ramadan M, Woodruff P, Santos M, Saqqur M, Shuaib A, Malik RA.

Sci Rep. 2021 Oct 05;11(1):19718. doi: 10.1038/s41598-021-99131-0.

In patients with acute ischemic stroke, pial collaterals play a key role in limiting neurological disability by maintaining blood flow to ischemic penumbra. We hypothesized that patient with poor pial collaterals will have greater corneal nerve and endothelial cell...

Calibration of two validated SARS-CoV-2 pseudovirus neutralization assays for COVID-19 vaccine evaluation.

Scientific reports

Huang Y, Borisov O, Kee JJ, Carpp LN, Wrin T, Cai S, Sarzotti-Kelsoe M, McDanal C, Eaton A, Pajon R, Hural J, Posavad CM, Gill K, Karuna S, Corey L, McElrath MJ, Gilbert PB, Petropoulos CJ, Montefiori DC.

Sci Rep. 2021 Dec 14;11(1):23921. doi: 10.1038/s41598-021-03154-6.

Vaccine-induced neutralizing antibodies (nAbs) are key biomarkers considered to be associated with vaccine efficacy. In United States government-sponsored phase 3 efficacy trials of COVID-19 vaccines, nAbs are measured by two different validated pseudovirus-based SARS-CoV-2 neutralization assays, with each trial...
