BACKGROUND CONTEXT: Quantitative computed tomography (QCT) of the lumbar spine is used as an alternative to dual-energy X-ray absorptiometry in assessing bone mineral density (BMD). The average BMD of L1-L2 is the standard reportable metric used for diagnostic purposes according to current recommendations. The density of L1 and L2 has also been proposed as a reference value for the remaining lumbosacral vertebrae and is commonly used as a surrogate marker for overall bone health. Since regional BMD differences within the spine have been proposed, it is unclear if the L1-L2 average correlates with the remainder of the lumbosacral spine...

C-type natriuretic peptide (CNP) is believed to be produced locally in the kidneys and possess several renoprotective properties. In contrast, fibroblast growth factor (FGF) -23 elevates in the early stage of chronic kidney disease and predicts its outcomes. Currently, several studies have demonstrated that CNP and FGF-23 act through a close pathway, and moreover, FGF-23/mitogen-activated protein kinase (MAPK) can be obviously suppressed by CNP. In the present study, human mesangial cells (MCs) were incubated in serum-containing medium in the absence or presence of CNP (0, 10 and 100 pM) for 24, 48 and 72 h, respectively...

The mesophilic reactor (MR) exhibited advantages in biogas production and performance stability over thermophilic reactor (TR) during the long-term anaerobic digestion (AD) of food waste (FW) with stepwise organic loading rate elevating. It was interesting to explore the mechanism causing the divergences in performances between these two reactors. The microbial activity was compared on day 110 when TR began to deteriorate. The results show that MR had significantly higher specific acetoclastic methanogenic activities (SAMA) and specific propionate and butyrate oxidative activities (SPOA and SBOA) than TR...

Uveitis (UVT), an inflammatory disease of the eye significantly contributes to vision impairment and blindness. Uveitis is associated with systemic infectious and autoimmune diseases, but in most cases, the aetiology remains unidentified. Dysbiosis in the gut microbiome has been implicated in autoimmune diseases, inflammatory diseases, cancers and mental disorders. In a mice model of autoimmune UVT, it was observed that manipulating the gut microbiome reduces the inflammation and disease severity. Further, alterations in the bacterial gut microbiome and their metabolites were reported in UVT patients from a Chinese cohort...

Brood parasites lay their eggs in other females' nests, leaving the host parents to hatch and rear their young. Studying how brood parasites manipulate hosts into raising their young and how hosts detect parasitism provide important insights in the field of coevolutionary biology. Brood parasites, such as cuckoos and cowbirds, gain an evolutionary advantage because they do not have to pay the costs of rearing their own young. However, these costs select for host defenses against all developmental stages of parasites, including eggs, their young, and adults...

Malignant peripheral nerve sheath tumors (MPNST) are aggressive spindle cell neoplasms that may occur sporadically, often in association with radiation exposure, or in the clinical context of Neurofibromatosis type 1. MPNST are known to harbor genetic alterations affecting the function of polycomb repressive complex 2 (PRC2), resulting in profound changes to global H3K27me3 levels. Recent evidence suggests a link between the polycomb complex and DNA methylation. Given the established epigenetic alterations found in MPNST, we aimed to further explore global methylation changes including 5-methylcystosine (5mC), 5-hydroxymethylcytosine (5hmC), and H3K27me3 levels using previously validated immunolabeling protocols in a representative cohort of 28 peripheral nerve sheath tumors (MPNST [n = 8], localized cutaneous neurofibroma [n = 10], and plexiform neurofibroma [n = 10])...

Purpose: Based on blood and sputum samples, up to 40% of patients with COPD have eosinophilic inflammation; however, there is little epidemiology data characterizing the health care burden within this sub-population. Given that COPD-attributable medical costs in the USA are predicted to approach $50 billion by 2020, we analyzed the effect of blood eosinophil counts and exacerbations on health care resource utilization and costs. Patients and methods: This cross-sectional study used electronic medical records and insurance claims data from the Reliant Medical Group (January 2011-December 2015)...

BACKGROUND: Colon cancer (CRC) is a heterogeneous disorder, arising from precursors-adenoma and serrated polyp. Previous studies have demonstrated the relationship between the human gut microbiota and CRC; however, its correlation to the different early precursors of CRC is not properly understood. Here, we studied the relationship between targeted gut bacteria and different colorectal polyp types, location, size and grade of dysplasia. MATERIAL AND METHODS: In the present case-control descriptive study, selected fecal bacteria were assessed in 118 patients, referred for standard screening colonoscopy, including 31 normal controls, 21 hyperplastic polyp (HP), 16 sessile serrated polyp (SSA), 29 tubular adenoma (TA) and 21 villous/tubuvillous polyp (VP/TVP) cases, between 2015 and 2017, by absolute quantitative real time PCR technique (q PCR) in different ethnicity of Iranian population...

Based on previous studies, empirical distribution of the bacterial burst size varies even in a population of isogenic bacteria. Since bacteriophage progenies increase linearly with time, it is the lysis time variation that results in the bacterial burst size variations. Here, the burst size variation is computationally modeled by considering the lysis time decisions as a game. Each player in the game is a bacteriophage that has initially infected and lysed its host bacterium. Also, the payoff of each burst size strategy is the average number of bacteria that are solely infected by the bacteriophage progenies after lysis...
