Blood microRNA expressions in patients with mild to moderate psoriasis and the relationship between microRNAs and psoriasis activity

An. bras. dermatol; 95 (6), 2020
Abstract Background: In recent studies, microRNAs (mi-RNAs) have been shown to play an important role in psoriasis pathogenesis. However, studies evaluating mi-RNAs in the blood of psoriasis patients including a large number of mi-RNA panels are scarce. Objective: The authors aimed to assess mi-RNA exp...

Clinical significance of p27 Kip1 expression in advanced ovarian cancer

Appl. cancer res; 40 (), 2020
Background: Ovarian cancer is the most common gynecological malignancy. In patients with advanced ovarian cancer, some biological parameters have prognostic implementations. P27kip1 is an inhibitor of a cycline-dependent kinase, its loss, can contribute to tumor progression. Objective: This study aimed t...

Cichoric acid from extracted Echinacea purpurea induces the proliferation and apoptosis of peripheral blood mononuclear cells from yaks

BACKGROUND: Cichoric acid (CA) is extracted from Echinacea purpurea. It is well known and widely used for its immunological function. However, the effect of CA on peripheral blood mononuclear cells (PBMCs) from yaks is still unclear. This study investigated the potential influences of CA on the prolifera...

Fructosan form Paenibacillus kribbensis PS04 enhance disease resistance against Rhizoctonia solani and tobacco mosaic virus

BACKGROUND: Rice sheath blight (caused by Rhizoctonia solani) and tobacco mosaic virus are very important plant diseases, causing a huge loss in global crop production. Paenibacillus kribbensis PS04 is a broad-spectrum biocontrol agent, used for controlling these diseases. Previously, extracellular polys...
