Development of Simultaneous Analytical Method of Three Polypeptide Toxins α-Amanitin, β-Amanitin and Phalloidin in Poisonous Mushrooms and Human Serum Using UHPLC-MS/MS. [PDF]

J Mass Spectrom
ABSTRACT Accidental ingestion of toxic mushrooms remains a global public health concern because of the presence of highly potent peptide toxins such as α‐amanitin, β‐amanitin, and phalloidin. These compounds exhibit strong hepatotoxicity and can lead to acute liver failure and death.

Mushroom ( Amanita phalloides) Poisoning: Mechanisms, Pathogenesis, Prognosis and Strategies of Treatment

مجلة علوم ذي قار, 2021
Poisoning due to mushroom consumption is uncommon, but it causes death by causing acute liver failure (ALF). The ingestion of Amanita phalloides, is one of the ultimate frequent causes of mushroom poisoning globally.

Cytology, function and dynamics of stem and progenitor cells in decapod crustaceans

Biological Reviews, Volume 97, Issue 2, Page 817-850, April 2022., 2022
ABSTRACT Stem cells play key roles in development, tissue homeostasis, regeneration, ageing and diseases. Comprehensive reviews on stem cells are available for the determinately growing mammals and insects and some lower invertebrates like hydra but are rare for larger, indeterminately growing invertebrates that can live for many decades.

Biomimicking Bone–Implant Interface Facilitates the Bioadaption of a New Degradable Magnesium Alloy to the Bone Tissue Microenvironment

Advanced Science, Volume 8, Issue 23, December 8, 2021., 2021
The spontaneously formed degradation layers at the bone–implant interface are the key to the superior performance of Mg–Si–Ca alloy, as they regulate the biodegradation behaviors of the implant to elicit an appropriate host response at different stages of bone healing.

Fluid shear stress activates YAP to promote epithelial–mesenchymal transition in hepatocellular carcinoma

Molecular Oncology, Volume 15, Issue 11, Page 3164-3183, November 2021., 2021
Here, we describe the underlying mechanism by which fluid shear stress (FSS) induces epithelial–mesenchymal transition (EMT) and enhances metastasis in hepatocellular carcinoma. Upon FSS, Yes‐associated protein (YAP) was released from its membrane binding partner integrin β subunits.

Sirtuin 1 ameliorates defenestration in hepatic sinusoidal endothelial cells during liver fibrosis via inhibiting stress‐induced premature senescence

Cell Proliferation, Volume 54, Issue 3, March 2021., 2021
SIRT1‐mediated deacetylation of p53 relieves NOX2‐dependent oxidative stress and inhibits progerin‐associated premature senescence to maintain fenestrae in HSECs. Abstract Objective Premature senescence is related to progerin and involves in endothelial dysfunction and liver diseases. Activating sirtuin 1 (SIRT1) ameliorates liver fibrosis.
