The incidence of early-onset colorectal cancer (EOCRC) is rising. Left-sided colorectal cancer (LCC) is associated with better survival compared to right-sided colon cancer (RCC) in metastatic disease. NCCN guidelines recommend the addition of EGFR inhibitors to KRAS/NRAS WT metastatic CRC originating from the left only. Whether laterality impacts survival in locoregional disease and EOCRC is of interest. 65,940 CRC cases from the National VA Cancer Cube Registry (2001-2015) were studied. EOCRC (2096 cases) was defined as CRC diagnosed at <50years. Using ICD codes, RCC was defined from the cecum to the hepatic flexure (C18.0-C18.3), and LCC from the splenic flexure to the rectum (C18.5-18.7; C19 and C20). EOCRC is more likely to originate from the left side (66.65% LCC in EOCRC vs. 58.77% in CRC). Overall, LCC has better 5-year Overall Survival (OS) than RCC in stages I (61.67% vs. 58.01%) and III (46.1% vs. 42.1%) and better 1-year OS in stage IV (57.79% vs. 49.49%). Stage II RCC has better 5-year OS than LCC (53.39% vs. 49.28%). In EOCRC, there is no statistically significant difference between LCC and RCC in stages I-III. Stage IV EOCRC patients with LCC and RCC have a 1-year OS of 73.23% and 59.84%, respectively. In EOCRC, LCC is associated with better OS than RCC only stage IV. In the overall population, LCC is associated with better OS in all stages except stage II. The better prognosis of stage II RCC might be due to the high incidence of mismatch repair deficient tumors in this subpopulation.In EOCRC, LCC is associated with better OS than RCC only stage IV. In the overall population, LCC is associated with better OS in all stages except stage II. The better prognosis of stage II RCC might be due to the high incidence of mismatch repair deficient tumors in this subpopulation.Nonavailability of glucose as a carbon source results in glyoxylate pathway activation, which metabolizes nonfermentable carbon for energy generation in Saccharomyces cerevisiae. Ucc1p of S. cerevisiae inhibits activation of the glyoxylate pathway by targeting Cit2p, a key glyoxylate enzyme for ubiquitin-mediated proteasomal degradation when glucose is available as a carbon source. Sro9p, a La-motif protein involved in RNA biogenesis, interacts physically with the messenger RNA of UCC1; however, its functional relevance is yet to be discovered. This study presents binary epistatic interaction between UCC1 and SRO9, with functional implication on the growth rate, response to genotoxic stress, resistance to apoptosis, and petite mutation. Cells with ucc1Δsro9Δ, as their genetic background, exhibit alteration in morphology, improvement in growth rate, resistance to apoptosis, and petite mutation. Moreover, the study indicates a cross-link between ubiquitin-proteasome system and RNA biogenesis and metabolism, with applications in industrial fermentation and screening for cancer therapeutics.What is the effect of activating a single modulatory neuronal receptor type on entire brain network dynamics? Can such effect be isolated at all? These are important questions because characterizing elementary neuronal processes that influence network activity across the given anatomical backbone is fundamental to guide theories of brain function. Here, we introduce the concept of the cortical 'receptome' taking into account the distribution and densities of expression of different modulatory receptor types across the brain's anatomical connectivity matrix. By modelling whole-brain dynamics in silico, we suggest a bidirectional coupling between modulatory neurotransmission and neuronal connectivity hardware exemplified by the impact of single serotonergic (5-HT) receptor types on cortical dynamics. As experimental support of this concept, we show how optogenetic tools enable specific activation of a single 5-HT receptor type across the cortex as well as in vivo measurement of its distinct effects on cortical processing. Altogether, we demonstrate how the structural neuronal connectivity backbone and its modulation by a single neurotransmitter system allow access to a rich repertoire of different brain states that are fundamental for flexible behaviour. We further propose that irregular receptor expression patterns-genetically predisposed or acquired during a lifetime-may predispose for neuropsychiatric disorders like addiction, depression and anxiety along with distinct changes in brain state. Our long-term vision is that such diseases could be treated through rationally targeted therapeutic interventions of high specificity to eventually recover natural transitions of brain states.For patients with stage IV colorectal cancer (CRC), curative-intent surgery has actively been performed for expecting prolonged survival outcomes. However, because the population with stage IV CRC is considerably heterogeneous, optimal selection of surgical candidate is inevitable to maximize survival outcomes. In the era of effective chemotherapy, there is an increasing need for a strategic use of chemotherapy as a part of multidisciplinary treatment to expand surgical indications and enhance the clinical outcomes. However, since the fate of each patient is difficult to predict at initial presentation, our clinical practice is rather "tailored", considering the anatomy, oncological behavior of tumor, response to chemotherapy, and patient's physical status. Given that surgery is the only treatment option for expecting cure of colorectal liver metastases (CLM), the main purpose of chemotherapy for potentially/marginally resectable disease is to clarify the likelihood of surgical benefit through testing the behavior of the tumor and to select an appropriate candidate for surgery. This process of clinical decision is actually optimization of the initial population for surgery through the optimization of treatment for each patient. In this article, theoretical bases of multidisciplinary management for CLM were revisited and the concept of "oncological optimization" underling our clinical decision was discussed. The aim of this study was to investigate the impact of periodontitis on oral health-related quality of life (OHQoL) using Oral-Dental Health-Related Quality of Life-United Kingdom (OHRQoL-UK) scale and evaluate the contributing factors. 50 patients with untreated periodontitis and 50 individuals without periodontitis were enrolled in the study. All subjects received detailed periodontal examination. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) measurements were examined. OHRQoL was assessed by the Oral Health Quality of Life-United Kingdom (OHRQoL-UK) scale. Symptoms of periodontitis were monitored by visual analogue scale (VAS). Socio-demographic characteristics, medical history, smoking status, hygiene habits of the participants were recorded. This study is registered at ClinicalTrials.gov as NCT04240014. Total OHRQoL-UK scores were 38.24±6.47 in periodontitis patients and 55.88±9.38 in non-periodontitis individuals (p<0.001). selleck chemicals The scores of all 4 parameters were significantly lower in patients with periodontitis compared to healthy individuals (p <0.
