Abstract:

Breast cancer is a disease in which malignant cells form in the tissues of the breast. The most common type of breast cancer is ductal carcinoma, which begins in the cells of the ducts. Cancer that begins in the lobes or lobules is called lobular carcinoma and is more often found in both breasts than are other types of breast cancer. Tamoxifen is a type of estrogen- suppressant, in several cases patients treated by Tamoxifen increased the risk rate for breast cancer, therefore, we hope to reduce the complications of endometrial cancer while treating breast cancer.

In the early experiment we used High throughout screening technology select compounds from the drug library and sensitive to gene signature which related to T cell associated genes CXCL9, CXCL10, CXCL11. We discover that MDA-MB-231 human triple negative breast cancer cell treated by RSC001 can induce chemokines also affect expression of STAT genes, classic pathway JAK-STAT will affect chemokines expression, chemokines CXCL10 and CXCL11 will recruit CD8+ T cell for attacking tumor cell. Therefore, though the interconnections between the pathway and chemokines, we need to explore more about RSC001 target point in TNBC cell also the relationship with STAT pathways.

Abstract:

Endosulfan sulfate (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9 methano-2,3,4-benzodioxathiepin-3,3-dioxide) is a major oxidized metabolite of endosulfan which is a broad-spectrum chlorinated cyclodiene insecticide. In this study, we used a GC-MS/MS based targeted metabolomic approach using MRM of metabolite to elucidate the toxicological effects of endosulfan sulfate in adult zebrafish. Zebrafish were exposed to endosulfan sulfate at concentrations of 1/10 LC50 and LC50 for 24 and 48 hours. After exposure, the fish was homogenized with liquid N2, extracted with 50% MeOH solution and dried before TMS derivatization (MSTFA+1% TMCS). On GC-MS/MS (Shimadzu TQ8040) MRM library of 381 metabolites were used for screening to detect overall 170 metabolites in zebrafish whole body. The PLS-DA score plot (SIMCA-P+) showed a good separation between the three experimental groups (control, 1/10 LC50, LC50) of 48 hours samples. Based on the VIP and
ANOVA results, 60 metabolites were identified for contributing significantly to the differences in the metabolic profile. Metabolic pathway analysis using MetaboAnalyst 4.0 revealed that those identified metabolites were important for the organism response to endosulfan sulfate. Several pathways were reported by metabolic pathway analysis included aminoacyl-tRNA biosynthesis, valine/leucine/isoleucine biosynthesis, alanine/aspartate/glutamate metabolism, glycerolipid metabolism, arginine/proline metabolism, citrate cycle (TCA cycle), glycine/serine/threonine metabolism, glyoxylate/dicarboxylate metabolism and pentose phosphate pathway. These results suggest that these pathways underwent significant perturbations over the exposure period. This study highlights the application of GC-MS/MS (MRM mode) based targeted metabolomics to understand molecularlevel toxicity of persistent organochlorine pesticides and the results will contributed to the environmental risk assessment of endosulfan sulfate in zebrafish.

Abstract:

Hydroponics consists of production of plants through the supply of required nutrients for their growth and development in the appropriate proportions and under controlled conditions, allowing the nutrients variation directly related to the production and metabolic composition. Recently metabolomics is used for the analysis of quality and searching of useful compounds in food and pharmaceutical industry. Medicinal plants are also known as functional foods due to its high content in secondary metabolites with important medicinal properties can be considered in the treatment of diseases. These compounds include the flavonoids and the isothiocyanates, the latter are synthesized as product of glucosinolates hydrolysis. Peppermint is an aromatic plant with high benefit due to its phytochemical content, so studying its metabolic production in hydroponic systems comprises great interest and applicability. The main objective was therefore to analyze the variation of volatile compound profiles (obtained from supercritical fluid extraction) for mint leaves in hydroponics growing. This research was conducted to design and construct six hydroponic system, they were divided into three systems with standard nutrient solution and other three with nutrient solution+foliar salicylic acid (2 mM). As results, particular changes were found in the profiles of mint-derived volatile metabolites. These changes were mediated by the selective occurrence and/or content of some monoterpenes such as L-menthone, pulegone and terpenes such as menthol. The profiling of volatile metabolites could be an excellent tool to evaluate the mint quality in hydroponics growing. This work was supported by Vicerrectoría de Investigaciones at UMNG Project INV-CIAS-2542.

Abstract:

According to American Society of Plastic Surgery, over 106,000 breast reconstruction were performed in 2018. After Mastectomy, “body image altered is the most common psychosocial concern associated with breast cancer, (Mohammad, Khan, and Vanaki, 2018). However, very few people understand the effectiveness of a nipple-tattooing until they get one. Studies have shown that the nipple-areola complex has a high correlation with overall patient satisfaction and acceptance of body image, (Evans, Rasako and Lenert, 2005). Therefore, construction or recreation of a nipple –areola complex that matches the former state in terms of shape, size, and color enhances the effectiveness of the procedure in boosting the self-image of the mastectomy patient. 3D Areolar-nipple micro-pigmentation (tattooing) is safe, non-surgical, it has been endorsed and used for years by medical surgeons in the medical field. Areolar micro-pigmentation procedure is carried out by trained & certified personnel who works with micro-pigmentation (tattooing). Re-creates an illusion of 3D areola and nipples to make the surgical area look more realistic. To carry out the procedure, patients determine the size, shape and color of pigment which is introduced into the dermis layer of the skin with a medical-grade tattoo machine that penetrates slightly deeper. With the right technology, complete nipple areola-nipple complex can draw attention away from the reconstructed breast mound and boosts the confidence of the patient. Mastectomy scar’s appearance can be softened, blended or reduced by tattooing the areolar scar using corrective pigment camouflage techniques.

Abstract:

Math-Physical Medicine approach (MPM) utilizes mathematics, physics, engineering models and computer science in medical research. Initially, the author spent four years of self-studying six chronic diseases and food nutrition to gain in-depth medical domain knowledge. During 2014, he defined metabolism as a nonlinear, dynamic and organic mathematical system having 10 categories with 500 elements. He then applied topology concept with partial differential equation and nonlinear algebra to construct a metabolism equation. He further defined and calculated two variables, metabolism index and general health status unit. During the past few years, he has collected and processed 1.5 million data. Since 2015, he developed prediction models, i.e. equations for both Postprandial Plasma Glucose (PPG) and Fasting Plasma Glucose (FPG).
He identified 19 influential factors for PPG and five factors for FPG. He developed the PPG model using optical physics and signal processing. Furthermore, by using both wave and energy theories, he extended his research into the risk probability of heart attack or stroke. In this risk assessment, he applied structural mechanics concepts, including elasticity, dynamic plastic and fracture mechanics, to simulate artery rupture and applied fluid dynamics concepts to simulate artery blockage. He further decomposed 12,000 glucose waveforms with 21,000 data and then re-integrated them into three distinctive PPG waveform types which revealed different personality traits and psychological behaviors of type-2 diabetes patients. Furthermore, he also applied fourier transform to conduct frequency domain analyses to discover some hidden characteristics of glucose waves. He then developed an AI Glucometer tool for patients to predict their weight, FPG, PPG and A1C. It uses various computer science tools, including big data analytics, machine learning and artificial intelligence to achieve very high accuracy (95% to
99%).

Abstract:

Introduction & Aim: Breast cancer is the most common cancer type among women and also the most common cause of cancer related death in women worldwide, including Latvia. During the period from 2009 until 2016, the mortality rates in Latvia have increased from 20,7 to 23,3 per 100,000 inhabitants. Metastatic axillary lymph nodes are one of the important factors predicting prognosis of breast cancer patients. The aim of this study was to determine the effect of the N ratio on patient survival.

Method: The study included 100 patients that had underwent mastectomy or breast conserving surgery with lymphadenectomy in the Oncology Centre of Latvia, from January-2010 until December-2011 with a diagnosis of breast cancer with positive axillary lymph nodes.  Patients were divided into two groups according to the N ratio: N ratio 0,2 or ≥0,2.

Results: Comparing the five years overall survival a statistically significant difference between groups was found (p=0,033). In the group where the N ratio was <0,2, 5-year overall survival rate was 85%, as opposed to 64% in the group where the N ratio was ≥0,2. When comparing the 5-year relapse free period, a statistically significant difference between the two groups was also found (p=0,039), showing a relapse-free 5-year period in 83% of the patients in the group with N ratio <0,2 and 64% of the patients with N ratio ≥0,2.

Conclusion: Patients with lower N ratio have a greater overall survival and relapse free period compared to patients with higher N ratio. Therefore, N ratio is a significant factor influencing the survival prognosis of breast cancer patients.

Abstract:

Fish is of increasing importance as a protein source in human diet. Farmed fish welfare is currently assessed using stress indicators such as the levels of cortisol, glucose and lactate in the blood plasma, but their reliability has been questioned due to high biological variability and fish adaptation processes. A multiomics approach can be a promisor strategy to discover reliable fish welfare biomarkers, since an integrated analysis can offer the possibility of understanding the complete flow of information in the fish biological system under stressful conditions. Our aim is to identify a restricted protein map as putative fish welfare biomarkers using proteomics, and integrate these results with complementary transcriptomics and metabolomics data, in order to validate these biomarkers as to achieve a global picture of the fish response to stress. Sparus aurata was reared under three different stressful conditions, in triplicate: overcrowding, repetitive net handling (air exposure) and hypoxia, using fish reared under optimal conditions as control.
Method: Fish were sampled after 45 days of trial and protein extracts were prepared from liver samples. Proteins were separated by 2D-DIGE and identified by MALDI-TOF/TOF MS. Putative welfare biomarkers were then chosen based on their stressrelated function, fold-change, score and other parameters and used for primer design. Total RNA was extracted from liver
samples using Trizol® reagent, with DNase treatment, and used for cDNA synthesis.
Results: The mRNA levels of the target genes were assessed by real-time PCR. Comparative proteomics show, in the liver, a total of 147 differentially expressed proteins among conditions, from which 24 were indicated as putative welfare biomarkers and chosen for their transcription level analysis.
Conclusion: This joint analysis provides a starter point for the development of more reliable fish welfare assessment measures
to improve aquaculture sustainability.

Abstract:

Kidney fibrosis is an anticipated outcome of possibly all types of progressive Chronic Kidney Disease (CKD). Epithelial- Mesenchymal Transition (EMT) signaling pathway is responsible for production of matrix-producing fibroblasts and myofibroblasts in diseased kidney. In this study, a discrete model of TGF-beta and CTGF was constructed using René Thomas formalism to investigate renal fibrosis turn over. The kinetic logic proposed by René Thomas is a renowned approach for modeling of Biological Regulatory Networks (BRNs). This modeling approach uses a set of constraints which represents the dynamics of the BRN thus analyzing the pathway and predicting critical trajectories that leads to a normal or diseased state. The molecular connection between TGF-beta, smad2/3 (transcription factor) phosphorylation and CTGF (Connective Tissue Growth Factor) is modeled using GenoTech. The order of BRN is CTGF, TGF-B and smad3 respectively. The predicted cycle depicts activation of TGF-B (TGF-β) via. cleavage of its own pro-domain (0, 1, 0) and presentation to TGFR-II receptor phosphorylating smad3 (smad2/3) in the state (0, 1, 1). Later TGF-B is turned off (0, 0, 1) thereby activating smad3 that
further stimulates the expression of CTGF in the state (1, 0, 1) and itself turns off in (1, 0, 0). Elevated CTGF expression reactivates TGF-B (1, 1, 0) and the cycle continues. The predicted model has generated one cycle and two steady states. Cyclic behavior in this study represents the diseased state in which all three proteins contribute to renal fibrosis. The proposed model is in accordance with the experimental findings of the existing diseased state. Extended cycle results in enhanced CTGF expression through smad2/3 and smad4 translocation in the nucleus. The results suggest that the system converges towards organ fibrogenesis if CTGF remains constructively active along with Smad2/3 and Smad4 that plays an important role in kidney fibrosis. Therefore, modeling regulatory pathways of kidney fibrosis will escort to the progress of therapeutic tools and real-world useful applications such as predictive and preventive medicine.
