Chemotherapy Enriches for Proinflammatory Macrophage Phenotypes that Support Cancer Stem-Like Cells and Disease Progression in Ovarian Cancer.

High-grade serous ovarian cancer remains a poorly understood disease with a high mortality rate. Although most patients respond to cytotoxic therapies, a majority will experience recurrence. This may be due to a minority of drug-resistant cancer stem-like cells (CSC) that survive chemotherapy and are capable of repopulating heterogeneous tumors.

Atlantic Salmon Pre-smolt Survivors of Infection Show Inhibited Cell-Mediated Adaptive Immune Response and a Higher Risk of Death During the Late Stage of Infection at Lower Water Temperatures.

Bacterial kidney disease (BKD) is widespread in many areas of the world and can cause substantial economic losses for the salmon aquaculture industry. The objective of this study was to investigate the pathophysiological response and gene expression profiles related to the immune response at different water temperatures and to identify the best immunopathological biomarkers to define a phenotype of resistance to BKD. The abundance of transcripts of in the head kidney was significantly higher in infected fish at 11°C.

Use of a negative binomial distribution to describe the presence of Sphyrion laevigatum in Genypterus blacodes.

This paper describes the frequency and number of Sphyrion laevigatum in the skin of Genypterus blacodes, an important economic resource in Chile. The analysis of a spatial distribution model indicated that the parasites tended to cluster. Variations in the number of parasites per host could be described by a negative binomial distribution.

Hematological changes in Eleginops maclovinus during an experimental Caligus rogercresseyi infestation.

Eleginops maclovinus has been an important fishery resource in Chile since 1957. Caligus rogercresseyi is one of the most prevalent ectoparasite species found on E. maclovinus.

[Viability and efects of the probiotic lactobacillus aracaseissp aracasei in Chilean low-fat Gauda cheese].

The objective of this study is to infer the survival of the probiotic Lactobacillus paracasei ssp paracasei added during the processing of low-fat Gouda cheese, during the maturation (21 days) and the commercialization (14 days), in order to see the influence that this organism has on the quality of the product. The treatments were: TI (control): Gouda with normal fat content; T2: Low fat Gouda cheese (QGS) T3: QGS, with additional probiotic added with the initial culture; T4: QGS, with the probiotic added in the cooking of the curd. For the count of the probiotic, the methodology was used set forth by the American Public Health Association, (APHA), proteolysis by the method of soluble tyrosine in trichloroacetic acid (TCA), and the physical and chemical analysis using the methods standardized by the International Dairy Federation, and Chilean normative.
