Anterior segment vascular casting [PDF]

open access: yesEye, 1989
Vascular corrosion casting provides a permanent three-dimensional record of the deeper vasculature of the anterior segment whereas fluorescein angiography allows clinical examination of superficial vessels. Morphological findings on scanning electron microscopy of vascular casts of the anterior segment in sheep are presented and compared with that of ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Monoclonal gammopathy presenting with paraproteinemic keratopathy documented with anterior segment OCT: a case report

open access: yesBMC Ophthalmology
Background Paraproteinemic keratopathy (PPK) is a rare ocular manifestation of monoclonal gammopathies such as monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), and multiple myeloma (MM).

Toxic keratitis after use of wrongly labeled non-ophthalmic medicatio

open access: yesSaudi Pharmaceutical Journal, 2017
We present a 24-year-old female with trauma to her right eye. The patient was prescribed topical Tobramicin-dexamethasone eye drops but the pharmacy dispensed diclofenac diethyl amine ointment.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

CORNEAL ULCER AND ASSOCIATED RISK FACTORS IN BANGLADESH: A RURAL-URBAN COMPARISON [PDF]

open access: yesEgyptian Journal of Clinical Ophthalmology
Purpose: In most developing countries, corneal infections are the most common cause ofblindness after unoperated cataracts. We examined risk factors for corneal ulcers and made acomparison between rural and urban patients.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

open access: yesFEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.
