Evaluation of conventional imaging techniques on preoperative localization in primary hyperparathyroidism [PDF]

open access: yes, 2015
We aimed to evaluate the diagnostic and preoperative localization capacity of Tc-99m methoxyisobutylnitrile (MIBI) parathyroid scintigraphy and ultrasonography (USG) in enlarged parathyroid glands in the primary hyperparathyroidism (pH PT), as well as ...

Mitochondrial DNA Mutations in Oxyphilic and Chief Cell Parathyroid Adenomas [PDF]

open access: yes, 2011
Background: The potential pathogenetic significance of mitochondrial DNA (mtDNA) mutations in tumorigenesis is controversial. We hypothesized that benign tumorigenesis of a slowly replicating tissue like the human parathyroid might constitute an ...

Viridicatol from the Deep‐Sea‐Derived Fungus Alleviates Bone Loss by Targeting the Wnt/SHN3 Pathway

open access: yesAdvanced Science, EarlyView.
Viridicatol (VDC), isolated from the deep‐sea‐derived fungus, enhances osteogenesis in vitro and in vivo by targeting Wnt/SHN3 signaling pathway. It can be delivered via engineered nanovesicles to mitigate bone loss of osteoporosis, fracture repair, and osteogenesis imperfecta.

Investigating heterogeneous PSMA ligand uptake inside parotid glands [PDF]

open access: yesPhysica Medica: European Journal of Medical Physics, 2024
The purpose was to investigate the spatial heterogeneity of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) uptake within parotid glands. We aim to quantify patterns in well-defined regions to facilitate further investigations.

1,25-(OH)2D receptors are decreased in parathyroid glands from chronically uremic dogs [PDF]

open access: yes, 1989
1,25-(OH)2D receptors are decreased in parathyroid glands from chronically uremic dogs. 1,25-(OH)2D has been shown to suppress the synthesis and secretion of parathyroid hormone in vivo and in dispersed parathyroid cell cultures. Control of transcription

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

open access: yesAdvanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Prevalence of Thymic Parathyroids in Primary Hyperparathyroidism During Radioguided Parathyroidectomy

open access: yesClinical Medicine Insights: Endocrinology and Diabetes, 2019
Background: Radioguided surgery has been an effective tool for identifying hyperfunctioning parathyroid glands during routine parathyroidectomy for hyperparathyroidism.

Reflections of the Anesthetic Management in a Case of Parathyroid Adenoma: A Case Report

open access: yesArchives of Anesthesia and Critical Care, 2023
Parathyroid adenomas are usually an incidental finding and present more commonly in women. The parathyroid gland releases parathyroid hormone(PTH), which is essential to maintain calcium homeostasis.

Regulation of mammary gland branching morphogenesis by the extracellular matrix and its remodeling enzymes. [PDF]

open access: yes, 2003
A considerable body of research indicates that mammary gland branching morphogenesis is dependent, in part, on the extracellular matrix (ECM), ECM-receptors, such as integrins and other ECM receptors, and ECM-degrading enzymes, including matrix ...

Gut Microbiota Modulates Obesity‐Associated Skeletal Deterioration Through Macrophage Aging and Grancalcin Secretion

open access: yesAdvanced Science, EarlyView.
Obese gut‐microbiota derived lipopolysaccharides (LPS) induce bone marrow macrophage senescence and GCA secretion via activating TLR4/NF‐κB/MAPKs pathway. Clinically, obese patients are associated with higher serum GCA levels. Mice with depletion of GCA gene show resistance to skeletal deterioration caused by obesity and LPS‐induced chronic ...
