Phylogenetic analyses of the most common pathogens revealed similar genotypes circulating between species. Our data suggest that, in Australian orchards, pathogen prevalence in honey bees is a good predictor of pathogen prevalence in native pollinators, which raises concerns about how the viral landscape may change in native taxa if, or when, Varroa arrives. Deaminations C->T and A->G are frequent mutations producing nucleotide content gradients across genomes proportional to singlestrandedness during replication/transcription. Hence, within single codons, deamination risks increase from first to third codon positions, while second codon positions are functionally most crucial. Here genetic codes are analyzed assuming that after anticodons protected codons from deaminations, first and second codon positions swapped (N2N1N3->N1N2N3), with lowest deamination risks for N2 in presumed primitive N2N1N3 codons. this website N2N1N3, not standard N1N2N3, codon structure minimizes deaminations inversely proportionally to cognate amino acid hydrophobicity and parallel betasheet conformational preference. For N1N2N3, deamination minimization increases with genetic code integration order of cognate amino acids during the presumed N2N1N3->N1N2N3 codon structure transition, protein synthesis combined direct codon-amino acid interactions for late amino acids and tRNA-based translation for early amino acids. Hence N2N1N3 codons would correspond to tRNA-free translation by spontaneous codon-amino acid affinities, and tRNA-mediated translation presumably caused N2N1N3->N1N2N3 swaps. Results show that rational, not arbitrary rules link codon and amino acid structures. Some analyses detect mitochondrial RNAs and peptides in public data corresponding to systematic position swaps, suggesting occasional swapping polymerase activity. PURPOSE Radical nephroureterectomy (RNU) is the primary treatment strategy for upper urinary tract urothelial carcinoma (UTUC); however, the prognosis is poor and recurrences are common. The risk factors for intravesical recurrence (IVR) remain inconsistent and unclear. Thus, we have identified the risk factors for IVR in patients with organ-confined UTUC. METHODS We retrospectively studied 229 patients with UTUC who underwent RNU combined with bladder cuff resection at our center between 1 January 2010 and 31 December 2015. After propensity score-matching, 204 patients were included in our study. Patient demographics, co-morbidities, and peri-operative data were recorded. Univariate and multivariate Cox proportional hazard regression were used to estimate the hazard ratio and 95% confidence intervals. Overall (OS) and cancer-specific survival (CSS) were measured using the Kaplan-Meier curve with a log-rank test. A p-value less then 0.05 was considered statistically significant. RESULTS Of the 229 patients, 42 (18.3%) had IVR after 40 months (range, 24-56 months) follow-up. In the matched group, the independent risk factors for IVR were tumor diameter (HR = 2.690, p = 0.038) and tumor stage (T3 vs. T1, HR = 3.363, p = 0.019; T2 vs. T1, HR = 2.835, p = 0.022). OS and CSS were poor in patients with IVR than patients without IVR (p  less then  0.0001). CONCLUSIONS In this propensity score-matched case-control study, tumor diameter and tumor stage were shown to be independent risk factors for IVR in patients with organ-confined UTUC. Moreover, patients with IVR had poor prognosis than patients without IVR. Thus, more active postoperative surveillance and treatment strategies should be adopted for these patients, which may help improve treatment outcomes. BACKGROUND Patients with mild traumatic brain injury (mTBI) are frequently transferred to level 1 trauma centers (L1TC) if they have minor findings on a computerized tomographic scan of the head due to the absence of continuous neurosurgical coverage in community hospitals (CH). We hypothesized that such patients can be safely managed at community hospitals with a qualified Trauma team. METHODS This is a multicentered Retrospective Cohort Study. Patients with mild Traumatic Brain Injury (defined as Glasgow Coma Scale [GCS] 13-15 at presentation) and with minor findings on head Computerized Tomography (CT) presenting at a L1TC or 4 Community Hospitals between March 1st, 2012 and February 28th, 2014 were included. All these community hospitals are Level III Trauma center with a well-organized trauma team. Minor CT findings were defined as 1) epidural hematoma less then 2 mm; 2) subarachnoid hemorrhage less then 2 mm; 3) subdural hematoma less then 4 mm; 4) intraparenchymal hemorrhage less then 5 mm; 5) minor pnnitoring device (ICP) or a neurosurgical operation and complications and mortality rates were similar among the groups. CONCLUSIONS Patients with mild TBI and minor findings on head CT can be safely managed at CH with qualified Trauma Teams. LEVEL OF EVIDENCE Therapeutic/Care Management Study, Level IVhbv. Processing numerosities relies on the innate capacity to understand and manipulate the number of items in a set, and to additional abilities such as inhibitory skills -which are known to be linked to brain oscillations in the alpha range. Whether these inhibitory skills are causally linked to numerosity processing and critical for it is unclear. To address this question, we used alpha-based brain stimulation (transcranial alternate current stimulation, tACS) to target inhibitory abilities in the context of numerosity discrimination. Twenty-nine young adults received bilateral tACS to the parietal lobe, a brain region critical for numerical processes. tACS at target (alpha, 10 Hz), control oscillation frequencies (theta, 4 Hz; beta, 22 Hz; sham, no stimulation), and control areas (bilateral frontal regions) was paired to an established numerosity paradigm that allows distinguishing between congruent and incongruent numerosity trials, the latter requiring to inhibit task-irrelevant information. Performance significantly and specifically worsened in incongruent numerosity trials following bilateral parietal alpha-tACS relative to sham and to the other stimulations used, possibly due to the desynchronization of parietal neuronal oscillations in the alpha range. No significant changes in performance were observed in parietal beta and theta-tACS, relative to sham, nor in frontal alpha-tACS. Likewise, there were no changes in performing congruent numerosity trials. link2 We therefore concluded that parietal alpha oscillations are causally linked to inhibitory abilities, and reinforced the view that these abilities are intrinsic to numerosity discrimination. V.BACKGROUND Obesity is a major public health problem whose prevalence has been rapidly increasing in the United States (U.S), and globally. It is one of the leading causes of preventable deaths globally and contributes to the development of many diseases. METHODS The search was limited to studies published in English and other languages involving both animal and human subjects. Articles selected included preclinical studies, randomized clinical trials RCTs, observational studies, meta-analyses, narrative and systemic reviews providing primary quantitative data with a measure of obesity or food addiction as an outcome. Over 5000 articles were found in the first round of search which was filtered to 506 articles. RESULTS Oxidative stress plays a critical role in food addiction and is both a cause and mediator of obesity. Reactive oxygen species play a direct role in adipogenesis and oxidative stress modulates all factors involved in obesity including genetics, sleep, gut microbiome, insulin, ghrelin, inflammation, adipokines, leptin, stress, HPA axis, and the hypothalamus. CONCLUSIONS The idea of thinking of combating obesity from the lens of calorie count, low carbohydrate, high or low-fat, vegetarian, vegan, plant-based, or animal-based diet is fundamentally wrong. The best way to look at obesity is through the framework of systemic redox homeostasis. Since redox homeostasis is tilted towards increased reactive oxygen species production, and excessive antioxidant intake can result in oxidative stress, an antioxidant and prooxidant food ratio of 23 per meal is the ideal nutritional ratio for good health and ideal weight. A ratio of 34 is ideal for obese individuals because of their state of chronic oxidative stress and inflammation. Physical activity, sleep quality, psychological stress, maternal prenatal diet and oxidative stress promoting disease conditions are important modulators of oxidative stress and obesity. BACKGROUND Periodontitis is the inflammation of the tooth-supporting structures and is one of the most common diseases of the oral cavity. The outcome of periodontal infections is tooth loss due to a lack of alveolar bone support. Osteoclasts are giant, multi-nucleated, and bone-resorbing cells that are central for many osteolytic diseases, including periodontitis. Receptor activator of nuclear factor-kB ligand (RANKL) is the principal factor involved in osteoclast differentiation, activation, and survival. However, under pathological conditions, a variety of pro-inflammatory cytokines secreted by activated immune cells also contribute to osteoclast differentiation and activity. Lipopolysaccharide (LPS) is a vital component of the outer membrane of the Gram-negative bacteria. It binds to the Toll-like receptors (TLRs) expressed in many cells and elicits an immune response. HIGHLIGHTS The presence of bacterial LPS in the periodontal area stimulates the secretion of RANKL as well as other inflammatory mediators, activating the process of osteoclastogenesis. RANKL, either independently or synergistically with LPS, can regulate osteoclastogenesis, while LPS alone cannot. MicroRNA, IL-22, M1/M2 macrophages, and memory B cells have recently been shown to modulate osteoclastogenesis in periodontal diseases. CONCLUSION In this review, we summarize the mechanism of osteoclastogenesis accompanying periodontal diseases at the cellular level. We discuss a) the effects of LPS/TLR signaling and other cytokines on RANKL-dependent and -independent mechanisms involved in osteoclastogenesis; b) the recently identified role of several endogenous factors such as miRNA, IL-22, M1/M2 macrophages, and memory B cells in regulating osteoclastogenesis during periodontal pathogenesis. V.Williams syndrome (WS) is a rare neurodevelopmental disorder associated to a hemizygous deletion of 28 genes located on chromosome 7q11.23. WS affected subjects frequently suffer from several endocrine abnormalities including hypothyroidism due to defects in thyroid morphology. To date, several genes involved in thyroid dysgenesis have been identified, nonetheless, none of them is located in the 7q11.23 region. Thus, the hypothyroidism-linked molecular features in WS are not yet known. link3 In this study we focused on one of the WS deleted gene, BAZ1B, demonstrating that its downregulation in thyroid cells leads to cell viability and survival decrement. Taking together, our results show that BAZ1B could be the mainly responsible for thyroid defects observed in some of WS patients and that these alterations are activated by PTEN-mediated mechanisms. Osteogenesis imperfecta (OI) is commonly caused by monoallelic mutations in COL1A1 or COL1A2. Biallelic mutations are extremely rare. Only five previous reports have identified seven OI patients with homozygous mutations in COL1A2. OI is a genetically and phenotypically heterogeneous disorder which challenges an establishment of genotype-phenotype correlation. Notably, more than thirty patients with OI possess the heterozygous mutation, p.Gly337Ser, in COL1A2. Their clinical severity ranges from mild OI type I to severe types III and IV. Here, we report a 17-year-old Thai female with recurrent bone fractures, short stature, blue sclerae, triangular face, missing teeth, dentinogenesis imperfecta (DI), skeletal deformities, and scoliosis. She was diagnosed with OI type III. Her parents were second-cousin-once-removed. The father was a professional Thai boxer. Both had normal bone mineral density, no history of bone fractures, and only teeth problems. They were diagnosed with DI without OI. Whole exome sequencing identified that the proband harbored the homozygous mutation, c.
