Porcine oocyte maturation in vitro : role of cAMP and oocyte-secreted factors: a practical approach [PDF]

, 2016
Polyspermy or the penetration of more than one sperm cell remains a problem during porcine in vitro fertilization (IVF). After in vitro culture of porcine zygotes, only a low percentage of blastocysts develop and their quality is inferior to that of in ...

Membrane‐type I metalloproteinase (MT1‐MMP): A key modifier of extracellular matrix microenvironment

The FEBS Journal, EarlyView.
MT1‐MMP: A cellular microenvironment modifier. MT1‐MMP is a major cellular microenvironment modifier, maintaining collagen homeostasis by degrading excess collagen (A), creating a migration path in motile cells such as cancer cells (B), modulating local microenvironmental signaling by cleaving transmembrane receptors (C), and destroying tissue ...

Parathyroid hormone-related protein activates HSCs via hedgehog signalling during liver fibrosis development

Artificial Cells, Nanomedicine, and Biotechnology, 2019
Recently, we showed that parathyroid hormone-like hormone (PTHLH), a cytokine-like polyprotein, is critical for extracellular matrix (ECM) deposition through the activation of hepatic stellate cells (HSCs). Here, we show that N-terminal PTHLH is secreted

Iron Overload: Pathophysiology, Diagnosis and Monitoring

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Iron overload is associated with significant health risks, underscoring the importance of understanding its pathophysiology as well as establishing accurate diagnostic and monitoring methods. Chronic iron overload is associated with either genetic disorders characterized by excessive iron accumulation (hereditary hemochromatosis), or is ...

Induced Pluripotent Stem Cell‐Derived Parathyroid Organoids Resemble Parathyroid Morphology and Function

Advanced Science
The primary role of the parathyroid glands is to maintain calcium homeostasis through the secretion of parathyroid hormone (PTH). The limited proliferative capacity and differentiation of parathyroid cells hinder the generation of cell therapy options ...

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

Journal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

Systemic, Lifestyle and Environmental Modifying Factors in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
A variety of impacting factors in the pathogenesis of periodontitis exist, including systemic, lifestyle, and environmental factors. This review highlights the manifold mechanistic aspects of the link between the pathogenesis of periodontitis, addressing these numerous factors to supplement the long‐standing knowledge of the progression of the disease.

Retention of differentiated properties in an established dog kidney epithelial cell line (MDCK). [PDF]

, 1979
Madin-Darby canine kidney (MDCK) cells grown in tissue culture have the morphological properties of distal tubular epithelial cells, form tight junctions, and lack several proximal tubular enzyme markers.

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.
