Optimized S-Curve Transformation and Wavelets-Based Fusion for Contrast Elevation of Breast Tomograms and Mammograms.

For the purpose of accuracy in detection and diagnosis, Computer-Aided Diagnosis (CAD) is preferred by radiologists for the analysis of Breast Cancer. However, the presence of noise, artifacts, and poor contrast in breast images during acquisition highlights the need for sophisticated enhancement techniques for the proper visualization of region-of-interest (ROI). In this work, contrast elevation of breast mammographic and tomographic images is performed with an improved S-Curve transform using the Particle Swarm Optimization (PSO) algorithm.

Potential Utility of Synthetic D-Lactate Polymers in Skin Cancer.

Increased breakdown of glucose through glycolysis in both aerobic and anaerobic conditions is a hallmark feature of mammalian cancer and leads to increased production of L-lactate. The high-level lactate present within the tumor microenvironment is reused as a crucial biofuel to support rapid cancer cell proliferation, survival, and immune evasion. Inhibitors that target the glycolysis process are being developed for cancer therapy.

Simultaneous Visualization of RNA and Protein Expression in Tissue Using a Combined RNAscope™ In Situ Hybridization and Immunofluorescence Protocol.

Gene expression analysis is critical to precisely characterize complex tissues and provide insight into a disease condition. Techniques like PCR, sequencing, and northern blotting are highly sensitive and specific but are unable to provide information about spatial positioning of target genes. Visualization of gene expression with a spatial context can be critical in identifying complex milieus in heterogenous tissues like tumors.

UBE2N Promotes Melanoma Growth via MEK/FRA1/SOX10 Signaling.

UBE2N is a K63-specific ubiquitin conjugase linked to various immune disorders and cancer. Here, we demonstrate that UBE2N and its partners UBE2V1 and UBE2V2 are highly expressed in malignant melanoma. Silencing of UBE2N and its partners significantly decreased melanoma cell proliferation and subcutaneous tumor growth.

Whole flaxseed diet alters estrogen metabolism to promote 2-methoxtestradiol-induced apoptosis in hen ovarian cancer.

The study reported here demonstrates that a flaxseed-supplemented diet causes ovarian tumors in the laying hen to undergo apoptosis, resulting in a reduction of tumor burden, reducing the frequency and severity of ovarian cancer. We have previously shown in normal ovaries that flaxseed and its components down-regulate ERalpha and alter the expression of enzymes that metabolize estrogen. In this study, we analyzed the effects of the two main components of whole flaxseed, ligan and omega 3 fatty acids on estrogen metabolism and the estrogen receptor in ovarian tumors.

Flaxseed and its components differentially affect estrogen targets in pre-neoplastic hen ovaries.

Flaxseed has been studied for decades for its health benefits that include anti-cancer, cardio-protective, anti-diabetic, anti-inflammatory properties. The biologically active components that mediate these effects are the omega-3 fatty acids and the lignan, secoisolariciresinol diglucoside. We have previously shown that whole flaxseed supplemented diet decreases the severity and incidence of ovarian cancer while a 15% dose of flaxseed is most protective against inflammation and estrogen-induced chemical and genotoxicity.

Flaxseed reduces the pro-carcinogenic micro-environment in the ovaries of normal hens by altering the PG and oestrogen pathways in a dose-dependent manner.

The objective of the present study was to find the optimum dose of flaxseed that would decrease PG and alter oestrogen pathway endpoints implicated in ovarian cancer. In the study, four groups of fifty 1.5-year-old chickens were fed different amounts of flaxseed (0, 5, 10 or 15% of their total diet) for 4 months and were then killed to collect blood and tissues.
