Fluorescence lifetime spectroscopy of tissue autofluorescence in normal and diseased colon measured ex vivo using a fiber-optic probe

open access: yes, 2013
We present an ex vivo study of temporally and spectrally resolved autofluorescence in a total of 47 endoscopic excision biopsy/resection specimens from colon, using pulsed excitation laser sources operating at wavelengths of 375 nm and 435 nm.

Integrative Analysis of Plasma Proteome and Genome Reveals Novel Drug Targets for Chronic Rhinosinusitis and Nasal Polyps

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and nasal polyps (NP) are chronic inflammatory conditions with unsatisfactory treatment outcomes due to frequent recurrence of refractory disease. Identifying new therapeutic targets is essential. Methods We conducted a proteome‐wide Mendelian randomization (MR) analysis by integrating genome‐wide ...

Sex Hormones and the Risk of Nasal Polyps: A Two‐Sample Mendelian Randomization Study

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective The pathophysiological roles of sex hormones in airway inflammation have drawn much attention recently. We aimed to explore the causal effect of sex hormones on chronic rhinosinusitis (CRS) and nasal polyps (NP) via a Mendelian randomization (MR) study.

Identification and Validation of Biomarkers in Chronic Rhinosinusitis With Nasal Polyps and Study of Their Associated Mechanisms

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Cell senescence (CS) and lipid metabolism (LM) disorders have been reported in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the mechanism is still unclear. Methods Data were obtained from public databases; differential expression analysis and machine learning were performed to identify biomarkers and to understand the

Dietary resilience of coral reef fishes to habitat degradation

open access: yesJournal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Trends in the Use and Indications for Intracytoplasmic Sperm Injection Between 2005 and 2017: A State‐Wide Descriptive Cohort Analysis

open access: yesAustralian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background Intracytoplasmic sperm injection (ICSI) was first developed to overcome male factor infertility. ICSI has increased in uptake globally, including in cases where its use is non‐essential for fertilisation. Aims To identify temporal trends in the use of, and indications for ICSI in an Australian context.
