The E3 Ubiquitin Protein Ligase LINCR Amplifies the TLR-Mediated Signals through Direct Degradation of MKP1.

Toll-like receptors (TLRs) induce innate immune responses through activation of intracellular signaling pathways, such as MAP kinase and NF-κB signaling pathways, and play an important role in host defense against bacterial or viral infections. Meanwhile, excessive activation of TLR signaling leads to a variety of inflammatory disorders, including autoimmune diseases. TLR signaling is therefore strictly controlled to balance optimal immune response and inflammation.

Industrially produced trans-fatty acids are potent promoters of DNA damage-induced apoptosis.

trans-Fatty acids (TFAs) are unsaturated fatty acids harboring at least one carbon-carbon double bond in trans configuration, which are categorized into two groups according to their origin: industrial and ruminant TFAs, hereafter called iTFAs and rTFAs, respectively. Numerous epidemiological studies have shown a specific link of iTFAs to various diseases, such as cardiovascular and neurodegenerative diseases. However, there is little evidence for underlying mechanisms that can explain the specific toxicity of iTFAs, and how to mitigate their toxicity.

Radiological characteristics of invasive micropapillary carcinoma of the breast.

Aim: To analyse the various imaging features of invasive micropapillary carcinoma (IMPC), a distinct variant of breast cancer, by mammography, ultrasound, and contrast-enhanced mammography.

Materials And Methods: This study included 68 female patients with histopathologically proven invasive micropapillary carcinoma who underwent mammography, ultrasound, and contrast-enhanced mammography examinations. The findings encountered by each imaging tool were analysed using the Breast Imaging Reporting and Data System (BI-RADS) lexicon.

A comprehensive toxicological analysis of trans-fatty acids (TFAs) reveals a pro-apoptotic action specific to industrial TFAs counteracted by polyunsaturated FAs.

trans-Fatty acids (TFAs) are unsaturated fatty acids containing at least one carbon-carbon double bond in trans configuration, which are classified into two groups according to their food source: industrial TFAs (iTFAs) and ruminant TFAs (rTFAs). Previous epidemiological evidence has demonstrated a preferential association of iTFAs, rather than rTFAs, with various diseases including cardiovascular diseases. However, it is still unknown how iTFAs exert their specific toxicity and what effective treatments are available to mitigate their toxicity.

Primary therapy of early breast cancer: Egyptian view of 2021 St. Gallen consensus.

Purpose: The theme of the St. Gallen International Breast Cancer Conference 2021 held virtually for the first time, due to the COVID-19 pandemic, was on tailoring therapies for patients with early breast cancer. A monkey survey that included an Egyptian Panel voted on most of the questions of the original St.
