Project description:Colorectal cancer is among the top three types of cancer that are most common and causes death worldwide.Nutritional support is widely used in elective colorectal surgery patients, as nutritional status is an important factor affecting clinical outcomes. European Society for Clinical Nutrition and Metabolism (ESPEN, 2016) emphasizes that nutritional supplementation with compounds such as amino acids, arginine, glutamine, and fish oil (omega 3) improves postoperative recovery.
Glutamine; it becomes an essential amino acid under stress. It is an energy substrate for cells such as intestinal mucosal cells and lymphocytes, a material for glutathione synthesis, and a potent antioxidant, which also increases heat shock protein expression. In stressful conditions, arginine is the primary fuel source for T cells and is required for nitric oxide synthesis; therefore, it helps maintain immune function. Omega 3; It plays a role in the treatment of inflammation and improves wound healing. In addition, EPA and DHA increase the immune response by improving lymphocyte function. RNA; They are essential for maturation, proliferation, and function in nearly all biochemical processes, in rapidly proliferating cells such as T cells. studies have shown that immunonutrition (IMN) formulas enriched with biologically active compounds may be more effective in reducing infection complications and shortening postoperative hospital stays.
This study aimed to investigate the additional effects of perioperative compared with preoperative immunonutrition on anthropometric, nutritional, and biochemical parameters, complications, and the length of hospital stay in patients with colorectal cancer.

Project description:Protein post-translational modifications (PTMs) have been associated with aging and age-related diseases. PTMs are particularly impactful in long-lived proteins, such as those found in the ocular lens, because they accumulate with age. Two post-translational modifications that lead to protein-protein crosslinks in aged and cataractous lenses are dehydroalanine (DHA) and dehydrobutyrine (DHB); formed from cysteine/serine and threonine residues, respectively. The purpose of this study was to quantitate DHA and DHB in human lens proteins as a function of age and cataract status. Human lenses of various ages were divided into five donor groups: transparent lenses (18–22-year-old, 48–64-year-old, and 70–93-year-old) and cataractous human lenses of two age groups (48–64-year-old lenses, and 70–93-year-old lenses) and were subjected to proteomic analysis. Relative DHA and DHB peptide levels were quantified and compared to their non-modified peptide counterparts. For most lens proteins containing DHA or DHB, higher amounts of DHA- and DHB-modified peptides were detected in aged and cataractous lenses. DHA-containing peptides were classified into three groups based on abundance changes with age and cataract: those that (1) increased only in age-related nuclear cataract (ARNC), (2) increased in aged and cataractous lenses, and (3) decreased in aged lenses and ARNC. There was no indication that DHA or DHB levels were dependent on lens region. In most donor groups, proteins with DHA and DHB were more likely to be found among urea-insoluble proteins rather than among water- or urea-soluble proteins. DHA and DHB formation may induce structural effects that make proteins less soluble in water that leads to age-related protein insolubility and possibly aggregation and light scattering.

Project description:This study elucidated the role of DHA-modulated genes in the development and growth of bluefin tuna (Thunnus thynnus) larvae ingesting increasing levels of DHA in their rotifer prey. The effect of feeding low, medium, and high rotifer (Brachionus rotundiformis) DHA levels (2.0, 3.6 and 10.9 mg DHA g-1 DW, respectively) was tested on 2-15 days post hatching (dph) bluefin tuna larvae. Larval DHA content markedly (P < 0.05) increased in a DHA dose-dependent manner (1.5, 3.9, 6.1 mg DHA g-1 DW larva, respectively), that was positively correlated with larval prey consumption, and growth (P < 0.05). Gene ontology enrichment analyses of DEGs demonstrated dietary DHA significantly (P < 0.05) affected different genes and biological processes at different developmental ages. The number of DHA up-regulated DEGs was highest in 10 dph larvae (408), compared to 5 (11) and 15 dph fish (34), and were mainly involved in neural and synaptic development in the brain and spinal cord. In contrast, DHA in older 15 dph larvae elicited fewer DEGs but played critical roles over a wider range of developing organs. The emerging picture underscores the importance of DHA-modulated gene expression as a driving force in bluefin tuna larval development and growth.

Project description:Enhanced Recovery After Surgery (ERAS) protocols were developed to standardize perioperative practice in colon surgery to reduce morbidity, improve recovery, and shorten length of stay (LOS). Better protocol adherence translates into fewer readmissions and complications, and better 5-year survival. Preoperative elements, especially nutrition and immunonutrition, are topics that need further development to become the standard of care. It has been widely reported that the prevalence of malnutrition reaches 40% in cancer patients at the time of diagnosis. Impaired nutritional status at the time of surgery and cancer-induced inflammation, along with postoperative inflammatory responses to major surgery, increase the risk of postoperative complications, along with a decrease in perceived quality of life.
Immunonutrition can modulate inflammation and reduce postoperative infections and shorten length of stay by counteracting the immune response induced by cancer. Adipose tissue has been shown to be a relevant source of inflammatory mediators, which may play a role in the promotion of tumor cachexia.
The present study is a multicenter randomized control study (RCT) designed to evaluate the effect of preoperative immunonutrition in patients with colorectal cancer eligible for elective minimally invasive procedures, evaluating in particular surgical site infection and length of hospital stay. A biopsy of subcutaneous adipose tissue and visceral adipose tissue will also be performed, in order to evaluate the differences between inflammatory infiltrate, degree of fibrosis and cross-sectional area of adipocytes compared to controls.

Project description:Immunonutrition (IN) appears to reduce infective complications and in-hospital length of stay (LOS) after gastrointestinal surgery. More specifically, it seems to be beneficial also in colorectal cancer surgery. Potential benefits of combining preoperative IN (PIN) with protocols of enhanced recovery after surgery (ERAS) in reducing LOS in laparoscopic surgery are yet to be determined.

Project description:Previously published results from our double-blind, placebo-controlled parallel study with docosahexaenoic acid (DHA) supplementation (3 g/d, 90 d) to hypertriglyceridemic men (39-66yr) showed that DHA reduced several risk factors for cardiovascular disease (CVD), including the plasma concentration of inflammatory markers. To determine the effect of DHA supplementation on the global gene expression pattern, we performed Affymetrix GeneChip microarray analysis of blood cells (treated with lipopolysaccharide (LPS) or vehicle) drawn before and after the supplementation from the hyperlipidemic men who participated in the previous study. Genes that were significantly differentially regulated by the LPS treatment and DHA supplementation were identified. Differential regulation of 18 genes was then confirmed by quantitative RT-PCR. Both microarray and qRT-PCR data showed that the expression of LDL receptor (LDLR), oxidized LDL receptor (OLR1), and cathepsin L1 (CTSL) was significantly suppressed by DHA supplementation; however, LPS stimulated the expression of LDLR and CTSL but not that of OLR1. LPS up-regulated and DHA suppressed the expression of prostaglandin E synthase (PTGES), PPAR delta, and various chemokines. Enrichment with Gene Ontology categories demonstrated that the genes related to transcription factor activity, immune responses, host defense responses, inflammatory responses, and apoptosis were inversely regulated by LPS and DHA. These results provide supporting evidence for the anti-inflammatory effects of DHA supplementation, and reveal previously unrecognized genes that are regulated by DHA, and are associated with risk factors of cardiovascular diseases.

Project description:Bovine blood neutrophil RNA from 4 primiparous Holstein cows was collected on days -7, 0, 0.25, and 1 (relative to parturition on day 0). RNA was pooled across the four animals at the independent time points to obtain the 20 ug necessary for use in a loop design. RNA pools were separated into two 10 ug aliquots prior to cDNA synthesis and dye coupling in a loop design. Each sample was labeled with Cy3 and Cy5 and run in paired hybridizations as follows: GSM8506 compaired day 0.25 and day -7, GSM8507 compaired day 1 and day 0, GSM8508 compaired day -7 and day 1, GSM8509 compaired day 0 and 0.25. This pairing strategy was utilized to directly compare day -7 samples with days 0.25 and 1 samples because results from previous experiments suggested that the most pronounced differences in gene expression would occur between these days.
