BACKGROUND: Human papillomavirus (HPV) vaccination has been routinely recommended at age 11-12 years in the United States for females since 2006 and males since 2011. Coverage can be estimated using self/parent-reported HPV vaccination collected in the National Health and Nutrition Examination Survey (NHANES) for a wider age range than other national surveys. We assessed vaccination coverage in 2015-2016, temporal trends by age, and the validity of self/parent-reported vaccination status...

A fucomannogalactan from Rhizoctonia solani biomass was obtained after hot aqueous extraction and purified by freeze-thaw cycles and gel filtration chromatography on Sepharose CL-6B. The polysaccharide was homogeneous after HPSEC/RID analysis (Mw /Mn  ~ 1.1), displaying an average molecular weight of 15.4 × 103  Da. Its chemical structure was determined by methylation analysis (GC/MS) and spectroscopy (FTIR, 1D and 2D NMR). The polysaccharide had a branched α-1,6-linked Galp backbone with 66% linear residues, a number of which were at O-3 methylated...

Critical to maintaining quality control in high-throughput screening is the need for constant monitoring of liquid-dispensing fidelity. Traditional methods involve operator intervention with gravimetric analysis to monitor the gross accuracy of full plate dispenses, visual verification of contents, or dedicated weigh stations on screening platforms that introduce potential bottlenecks and increase the plate-processing cycle time. We present a unique solution using open-source hardware, software, and 3D printing to automate dispenser accuracy determination by providing real-time dispense weight measurements via a network-connected precision balance...

Estimates of the 1.5 °C carbon budget vary widely among recent studies, emphasizing the need to better understand and quantify key sources of uncertainty. Here we quantify the impact of carbon cycle uncertainty and non-CO2 forcing on the 1.5 °C carbon budget in the context of a prescribed 1.5 °C temperature stabilization scenario. We use Bayes theorem to weight members of a perturbed parameter ensemble with varying land and ocean carbon uptake, to derive an estimate for the fossil fuel (FF) carbon budget of 469 PgC since 1850, with a 95% likelihood range of (411,528) PgC...

The hip joint replacement is one of the most successful orthopedic surgical procedures although it involves challenges to overcome. The patient group undergoing total hip arthroplasty now includes younger and more active patients who require a broad range of motion and a longer service lifetime for the replacement joint. It is well known that wear tests have a long duration and they are very expensive, thus studying the effects of geometry, loading, or alignment perturbations may be performed by Finite Element Analysis...

This study investigated the chemical characterization and antitumor effects of a polysaccharide from ramulus mori. A water-soluble polysaccharide, RMP1 with the estimated molecular weight of 137 kDa, was isolated and purified from ramulus mori through gel permeation chromatography. RMP1 is mainly composed of arabinose, xylose, glucose, galactose and rhamnose in a ratio of 0.56:0.37:0.17:1.00:0.08. Methylation and NMR analysis revealed that RMP1 had a backbone composed of 1,6-β-d-Galp, 1,3,6-β-d-Galp and 1,3-β-d-Galp residues, two main branches of 1,2-α-l-Araf, 1,3,6-β-d-Galp and 1,4-β-d-Xylp; it also had α-l-Araf and β-d-Glcp as terminals...

Nanocellulose sponge was fabricated by a facile method: freeze-drying of nanocellulose aqueous suspension to sponge state, following by hydrophobic treatment with stearoyl chloride at 50 °C for 1 h. The obtained nanocellulose sponge showed superhydrophobicity (160° of water contact angle) and superoleophilicity with high protection from water but selective absorption of oil. Its absorption capacities for various kinds of oil and non-polar liquids were 25-55 times higher than its dry weight and exhibited excellent selectivity for absorbing of oil which spilled on the surface of water or underwater with high separation efficiency...

Friction is the natural response of all tribosystems. In a total knee replacement (TKR) prosthetic device, its measurement is hindered by the complex geometry of its integrating parts and that of the testing simulation rig operating under the ISO 14243-3:2014 standard. To develop prediction models of the coefficient of friction (COF) between AISI 316L steel and ultra-high molecular weight polyethylene (UHMWPE) lubricated with fetal bovine serum dilutions, the arthrokinematics and loading conditions prescribed by the ISO 142433: 2014 standard were translated to a simpler geometrical setup, via Hertz contact theory...

Public transcriptome databases provide a valuable resource for genome‑wide co‑expression network analysis and investigation of the molecular mechanisms that underlie pathogenesis. To discover genes that may affect patient survival, a large‑scale analysis of human colorectal cancer (CRC) datasets that were retrieved from the NCBI Gene Expression Omnibus was performed. A gene co‑expression network was constructed using weighted gene co‑expression network analysis (WGCNA). A total of 18 co‑expressed gene modules were identified, of which two genes corresponded to cell migration and the cell cycle, two genes were involved in immune responses, two genes corresponded to mitochondrial function, and one gene corresponded to RNA splicing...

Anthricin (deoxypodophyllotoxin) is a major lignan in Anthriscus sylvestris and possesses many bioactivities such as antiproliferative, antitumor, anti‑platelet aggregation, antiviral and anti‑inflammatory actions. However, the anticancer effects of anthricin on A549 human non‑small cell lung cancer cells and potential molecular mechanisms remain unknown. Therefore, we investigated the anticancer effect of anthricin and the underlying mechanism in A549 cells. Anthricin (10‑200 nM) inhibited the viability of A549 cells in a dose‑ and time‑dependent manner...

To evaluate the potential of genomic selection (GS), a selection experiment with GS and phenotypic selection (PS) was performed in an allogamous crop, common buckwheat ( Fagopyrum esculentum Moench). To indirectly select for seed yield per unit area, which cannot be measured on a single-plant basis, a selection index was constructed from seven agro-morphological traits measurable on a single plant basis. Over 3 years, we performed two GS and one PS cycles per year for improvement in the selection index. In GS, a prediction model was updated every year on the basis of genotypes of 14,598-50,000 markers and phenotypes...
