Purpose: To evaluate the initial management of pediatric patients with lacrimal canalicular atresia (CA) involving the upper or lower eyelid.
Methods: The medical records of 15 children with symptoms of nasolacrimal duct (NLD) obstruction and CA of either the upper or lower eyelid treated from 1994 to 2014 were retrospectively reviewed. Surgical treatment consisted of nasolacrimal probing through the patent canaliculus. Preoperative findings, treatment, and outcomes were reviewed. Outcomes were considered good if the patients had resolution of signs and symptoms of lacrimal obstruction, fair if the symptoms improved and additional surgery was not required, and poor if additional lacrimal surgery was performed.
Results: CA was found in 19 eyes of 15 patients: 11 eyes had upper CA; 8 eyes, lower. All 11 eyes with upper CA improved after NLD probing through the patent lower canaliculus. Of the 8 eyes with lower CA, 4 (50%) had good outcomes and 4 eyes had poor outcomes after NLD probing through the patent upper canaliculus. All of the latter patients improved after subsequent treatment with balloon catheter dilation (BCD), monocanalicular stent placement, or both.
Conclusions: If a patient is found to have upper CA during initial surgery for NLD obstruction, NLD probing through the patent lower canaliculus has a good rate of surgical success. For patients with lower CA, the success rate of NLD probing through the upper canaliculus appears to be lower. Additional treatment during the initial surgery with either BCD or monocanalicular stent placement should be considered in these patients.

The cholinergic deficits and amyloid beta (Aβ) aggregation are the mainstream simultaneously observed pathologies during the progression of Alzheimer's disease (AD). Deposited Aβ plaques are considered to be the primary pathological hallmarks of AD and are contemplated as promising diagnostic biomarker. Herein, a series of novel theranostic agents were designed, synthesised and evaluated against cholinesterase (ChEs) enzymes and detection of Aβ species, which are major targets for development of therapeutics for AD.

Single-cell RNA sequencing (scRNA-seq) enables detailed characterization of cell states but often lacks insights into tissue clonal structures. Here, we present a protocol to probe cell states and clonal information simultaneously by enriching mitochondrial DNA (mtDNA) variants from 3'-barcoded full-length cDNA. We describe steps for input library preparation, mtDNA enrichment, PCR product cleanup, and paired-end sequencing.

The physical microenvironment plays a crucial role in tumor development, progression, metastasis and treatment. Recently, we proposed four physical hallmarks of cancer, with distinct origins and consequences, to characterize abnormalities in the physical tumor microenvironment: (1) elevated compressive-tensile solid stresses, (2) elevated interstitial fluid pressure and the resulting interstitial fluid flow, (3) altered material properties (for example, increased tissue stiffness) and (4) altered physical micro-architecture. As this emerging field of physical oncology is being advanced by tumor biologists, cell and developmental biologists, engineers, physicists and oncologists, there is a critical need for model systems and measurement tools to mechanistically probe these physical hallmarks.

The protective effect of naturally acquired humoral immunity against human papillomavirus (HPV) infection remains unclear. To investigate the role of infection-induced antibodies on HPV detection in heterosexual partners, we used data from 392 unvaccinated couples (females aged 18-25 years attended up to six visits over 2 years; males aged 17-37 years attended up to two visits 4 months apart) enrolled (2005-2011) in Montreal. Genital and blood samples were HPV DNA genotyped and tested for L1 antibody titers of 14 HPV genotypes.

High-charge micas exhibit improved adsorption properties and are a promising alternative clay material for the engineered barrier in deep geological repositories. When combined with Eu cations, they serve as an in situ luminescent probe for tracking the physical-chemical changes occurring in this engineered barrier over the long term. Therefore, a better understanding of the local environment of the lanthanide is highly desirable to comprehend the specific behavior of these systems.
