A Case of Paraganglioma as an Unusual Tenant of Gallbladder [PDF]

open access: yesJournal of Clinical and Diagnostic Research
Gallbladder paraganglioma is an exceptionally uncommon tumour. Paragangliomas are a subset of Neuroendocrine Neoplasms (NENs) called neurogenic NENs that arise from neural crest cells of the neuroectoderm.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Secretion of Intrinsic Factor from Cultured Rat Gastric Chief Cells [PDF]

open access: yes, 1994
Intrinsic factor (IF) is a vitamin B12 binding protein that is secreted from the gastric mucosa. We tested secretagogues which stimulate IF secretion in rat gastric perfusion and found that carbachol and cholecystokinin octapeptide (CCK-8) stimulated ...

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 ...

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Enlarged parathyroid glands with variable sonomorphology in a case of tertiary hyperparathyroidism: Sonographic-histopathologic correlation

open access: yesIndian Journal of Radiology and Imaging, 2016
The typical sonomorphology of homogeneously hypoechoic texture of an enlarged parathyroid gland (PG) is a reflection of uniform arrangement of the parathormone-producing chief cells.

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.

The disappearing chief cell phenomenon (DCP): A preliminary report

open access: yesJournal of British Surgery, 1983
Abstract The appearance of chief cells was studied in normal dogs and in dogs after anterior and bilateral highly selective vagotomy. The normal chief cell is columnar in shape, with a well-defined cell membrane, basal nucleus and basophilic cytoplasm. Many cells show what has been called the ‘disappearing chief cell phenomenon’—DCP. The
