Differential expression analysis and profiling of hepatic miRNA and isomiRNA in dengue hemorrhagic fever.

Dengue virus causes dengue hemorrhagic fever (DHF) and has been associated to fatal cases worldwide. The liver is one of the most important target tissues in severe cases, due to its intense viral replication and metabolic role. microRNAs role during infection is crucial to understand the regulatory mechanisms of DENV infection and can help in diagnostic and anti-viral therapies development.

Human kidney damage in fatal dengue hemorrhagic fever results of glomeruli injury mainly induced by IL17.

Acute kidney injury is an unusual complication during dengue infection. The objective of this study was to better identify the characteristics of glomerular changes focusing on in situ immune cells and cytokines. An immunohistochemical assay was performed on 20 kidney specimens from fatal human cases of dengue hemorrhagic fever (DHF).

High expression of retinoic acid receptors and synthetic enzymes in the human hippocampus.

Retinoic acid, the active form of the nutrient vitamin A, regulates several facets of neuronal plasticity in the hippocampus, including neurogenesis and synaptic strength, acting via specific retinoic acid receptors (RARs). Essential for conversion of vitamin A to retinoic acid is the enzyme retinaldehyde dehydrogenase (RALDH) and in the rodent hippocampus this is only present in the adjacent meninges where it must act as a locally released paracrine hormone. Little is known though about the expression of RALDHs and RARs in the human hippocampus.

Prognostic impact of p53, c-erbB-2 and epidermal growth factor receptor on head and neck carcinoma.

Context: p53, c-erbB-2 and epidermal growth factor receptor (EGFR) are cancer-related proteins that are usually expressed in head and neck squamous cell carcinoma (SCC). Their prognostic value remains controversial.

Objective: To evaluate the prognostic impact of p53, c-erbB-2 and EGFR expression in head and neck SCC.
