Interactions of anthropometric indices, rs9939609 FTO gene polymorphism and breast cancer: A case-control study

Contradictory results were reported on the effect of fat mass- and obesity-associated (FTO) gene and anthropometric measurements on breast cancer (BC). This study aimed to assess the interactions between rs9939609 polymorphism of FTO gene, anthropometric indices and BC risk in Iranian women. This case-control study was performed on 540 women including 180 women with BC and 360 healthy women in Tehran, Iran. Physical activity and dietary intakes were assessed by validated questionnaires. Data on sociodemographic and pathologic factors of the participants as well as their blood samples were collected. The rs9939609 FTO gene polymorphism was genotyped using the tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR). No significant association was found between BC and risk allele of FTO rs9939609 polymorphism after adjustments for the confounders. However, there was a significant association between rs9939609 polymorphism risk allele and BC risk in females with overweight, even after adjusting for age, family history of BC, abortion, BMI and the number of pregnancies (P < .05). The association was disappeared after further adjustments for lifestyle factors including smoking, alcohol consumption, calorie and macronutrients intake, and physical activity. The FTO gene polymorphism was associated with the risk of BC in overweight individuals. This association was influenced by environmental factors including diet, alcohol consumption and smoking. Future studies are required to confirm the association between the FTO gene and BC in overweight females and to identify the underlying mechanisms. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Use of Hanseniaspora guilliermondii and Hanseniaspora opuntiae to enhance the aromatic profile of beer in mixed-culture fermentation with Saccharomyces cerevisiae

Beer production is predominantly carried out by Saccharomyces species, such as S. cerevisiae and S. pastorianus. However, the introduction of non-Saccharomyces yeasts in the brewing process is now seen as a promising strategy to improve and differentiate the organoleptic profile of beer. In this study, 17 non-Saccharomyces strains of 12 distinct species were isolated and submitted to a preliminary sensory evaluation to determine their potential for beer bioflavouring. Hanseniaspora guilliermondii IST315 and H. opuntiae IST408 aroma profiles presented the highest acceptability and were described as having ‘fruity’ and ‘toffee’ notes, respectively. Their presence in mixed-culture fermentations with S. cerevisiae US-05 did not influence attenuation and ethanol concentration of beer but had a significant impact in its volatile composition. Notably, while both strains reduced the total amount of ethyl esters, H. guilliermondii IST315 greatly increased the concentration of acetate esters, especially when sequentially inoculated, leading to an 8.2-fold increase in phenylethyl acetate (‘rose’, ‘honey’ aroma) in the final beverage. These findings highlight the importance of non-Saccharomyces yeasts in shaping the aroma profile of beer and suggest a role for Hanseniaspora spp. in improving it.

Systemically impaired fracture healing in small animal research: A review of fracture repair models

Fracture healing is a complex process requiring mechanical stability, an osteoconductive matrix, and osteoinductive and osteogenic biology. This intricate process is easily disrupted by various patient factors such as chronic disease and lifestyle. As the medical complexity and age of patients with fractures continue to increase, the importance of developing relevant experimental models is becoming paramount in preclinical research. The objective of this review is to describe the most common small animal models of systemically impaired fracture healing used in the orthopedic literature including osteoporosis, diabetes mellitus, smoking, alcohol use, obesity, and ageing. This review will provide orthopedic researchers with a summary of current models of systemically impaired fracture healing used in small animals and present an overview of the methods of induction for each condition.

Single-wall carbon nanotube-containing cathode interfacial materials for high performance organic solar cells

Water/alcohol soluble cathode interfacial materials (CIMs) are playing important roles in optoelectronic devices such as organic light emitting diodes, perovskite solar cells and organic solar cells (OSCs). Herein, n-doped solution-processable single-wall carbon nanotubes (SWCNTs)-containing CIMs for OSCs are developed by dispersing SWCNTs to the typical CIMs perylene diimide (PDI) derivatives PDIN and PDINO. The Raman and X-ray photoelectron spectroscopy (XPS) measurement results illustrate the n-doped behavior of SWCNTs by PDIN/PDINO in the blend CIMs. The blended and n-doped SWCNTs can tune the work function and enhance the conductivity of the PDI-derivative/SWCNT (PDI-CNT) composite CIMs, and the composite CIMs can regulate and down-shift the work function of cathode, reduce the charge recombination, improve the charge extraction rate and enhance photovoltaic performance of the OSCs. High power conversion efficiency (PCE) of 17.1% and 17.7% are obtained for the OSCs based on PM6:Y6 and ternary PM6:Y6:PC71BM respectively with the PDI-CNT composites CIMs. These results indicate that the n-doped SWCNT-containing composites, like other n-doped nanomaterials such as zero dimensional fullerenes and two dimensional graphenes, are excellent CIMs for OSCs and could find potential applications in other optoelectronic devices.

TiO2 and TiO2/Ag nanofibers: template synthesis, structure, and photocatalytic properties

A fairly simple method for the synthesis of TiO2 and TiO2/Ag fibers containing the anatase-rutile-silver heterojunction with a combination of features attractive for photocatalysis is presented.TiO2 and TiO2/Ag fibers were synthesized by impregnating a cellulose template with alcohol solutions of titanium(IV) tetrabutoxide and silver nitrate, followed by annealing at 500-950 degrees C. The microstructure of the fibers was analyzed by X-ray diffraction, scanning electronic microscopy, high-resolution transmission electronic microscopy and IR Fourier spectroscopy. The thermal decomposition of silver nitrate results in the formation of silver particles (19 +/- 3 nm), does not affect the crystallite size of anatase (19 +/- 3 nm) and rutile (23 +/- 3 nm), and promotes rutilization of TiO2. The photocatalytic activities of the obtained TiO2/Ag fibers were investigated by evaluating the phenol degradation under visible light irradiation. The highest catalytic activity was shown by mixed-phase samples consisting of 40% rutile and 60% anatase.

Cellulose nanofibrils-based hybrid foam generated from Pickering emulsion toward high-performance microwave absorption

The development of multifunctional microwave absorbers that worked in complex environments remains challenging. In this study, oil-in-water Pickering emulsion gelation approach was combined with freeze-drying to prepare foam-based microwave absorbers along with appealing photo-thermal conversion and thermal insulation. In hybrid foam, cellulose nanofibrils (CNP) and polylactic acid (PLA) serve as three-dimensional skeleton, where carbon nanotubes (CNT) and Fe3O4 nanoparticles are homogeneously incorporated, which forms a conductive network with hetero-interfaces. The optimal reflection loss value of the foam reaches -65.14 dB with a thickness of 3.0 mm. The foam also demonstrate high photo-thermal conversion performance with its surface temperature up to 97 degrees C after irradiation under 1 Sun for 5 min. Additionally, the foam shows superior thermal insulation comparing with the commercial polyvinyl alcohol and polyurethane foams. This study may offer a promising approach to develop ultralight and high-performance microwave absorber with great potential for multifunctional applications.

Biotransformation of spent coffee grounds by fermentation with monocultures of Saccharomyces cerevisiae and Lachancea thermotolerans aided by yeast extracts

Spent coffee grounds (SCG) is a low-value solid food waste generated from the rising consumption of coffee. There is a need to transform the huge amount of SCG to value-added products such as alcoholic beverages. In this study, monocultures of Saccharomyces cerevisiae Merit and Lachancea thermotolerans Concerto were used to ferment SCG hydrolysates supplemented with yeast extracts. The addition of yeast extracts slightly enhanced the growth of both S. cerevisiae Merit and L. thermotolerans Concerto. In addition, the yeast extracts also increased the production of organic acids (e.g. succinic acid and acetic acid) and volatiles such as 2-phenylethyl alcohol and ethyl esters (e.g. ethyl octanoate and ethyl 2,4-hexadienoate). Furthermore, the supplementation of yeast extracts showed a more significant effect on the performance (e.g. yeast growth) of S. cerevisiae Merit than that on L. thermotolerans Concerto. Our results indicated that the addition of yeast extracts may provide a new strategy to enhance the transformation of SCG into a potential alcoholic beverage with flavor compound complexity.

Transcriptional regulation of alcohol induced liver fibrosis in a translational porcine hepatocellular carcinoma model

Hepatocellular carcinoma (HCC) is the 5th most common and 2nd deadliest cancer worldwide. HCC risk factors include alcohol induced liver cirrhosis, which prompts hepatic inflammation, cell necrosis, and fibrosis deposition. As 25% of HCC cases are associated with alcohol induced liver disease, understanding the effects of the cirrhotic liver microenvironment on HCC tumor biology and therapeutic responses are critical. This study utilized the Oncopig Cancer Model-a transgenic pig model that recapitulates human HCC through induced expression of KRAS(G12D) and TP53(R167H )driver mutations-to investigate the molecular mechanisms underlying alcohol induced liver disease. Oncopigs (n = 5) underwent fibrosis induction via infusion of ethanol and ethiodized oil (1:3 v/v dosed at 0.75 mL/kg) into the hepatic arterial circulation. Eight-weeks post induction, liver tissue samples from fibrotic and age-matched control (n = 5) Oncopigs were collected for histological evaluation and transcriptional profiling. Increased hepatic inflammation and fibrosis was observed in fibrotic Oncopigs via pathological assessment. Transcriptional profiling (RNA-seq) resulted in the identification of 4387 differentially expressed genes between Oncopig fibrotic and control livers. GO term enrichment analysis identified pathway alterations associated with cirrhosis progression in humans, including cell proliferation, angiogenesis, extracellular matrix deposition, and oxidation-reduction. Key alterations include activation of hepatic stellate cells, increased matrix metalloproteinase production, and altered expression of ABC and SLC transporter genes involved in transport of anticancer drugs.These results demonstrate Oncopig liver fibrosis recapitulates transcriptional hallmarks of human cirrhosis, making the Oncopig an ideal model for studying the effects of the cirrhotic liver microenvironment on HCC tumor biology and therapeutic response.

Processes of structure formation and paste matrix hydration with multilayer carbon nanotubes additives

The creation of high-strength materials with targeted structure formation and hydration to obtain building composites with a given set of properties represents a relevant area of the modern construction sector. This paper investigates promising nanomodifying additives i.e. multilayer carbon nanotubes along with an effective method to obtain a comprehensive nanomodifying additive through pre-ultrasonic dispersion of MWCNT globules of varying dispersive capacity in an isopropyl alcohol medium. The comprehensive nanomodifying additive obtained is characterized by high stability as well as a uniform distribution of carbon nanotubes in the additive. The Structure software package developed by the authors was used to study the structure of paste matrix at the mesastructural level. The modification of paste matrix by means of the developed comprehensive nanostructure additive reduces the crack length index to 113% with the crack length ratio and the crack shape ratio going down to 61% and 34%, respectively. The increase in the strength and durability of the compositions modified by the developed comprehensive nanomodifying additive is due to a more complete filling of the intergranular void with newly formed structures in the form of C-S-H (I), tobermorite and gel phases which enhance the degree of packing and density of the composite under examination. However, the share of nano – and micropores goes up by 1.21 and 1.31 times, respectively, while the share of meso – and macropores decreases by 1.51 and 5.25 times.

Development of bio oil and bio asphalt by hydrothermal liquefaction using lignocellulose

Bio asphalt is an organic polymer derived from biomass resources, which has the potential to partially or completely replace petroleum asphalt. This study used lignocellulose to prepare bio oil by hydrothermal liquefaction method. A mixed solvent of ethanol and ethylene glycol was introduced to increase the oil yield and decrease the reaction temperature. The oil yield reached the highest when solvent mixing ratio of 1:1, liquid-solid ratio of 6:1, catalyst dosage of 3%, and reaction temperature of 250 degrees C respectively. The bio oil and 50# asphalt were mixed in proportion sheared for 30 min (1000 rpm) under the condition of 135 degrees C to produce bio asphalt. The chemical structures and rheological properties of bio oil and bio asphalt were investigated and compared with petroleum asphalt. Fourier transform infrared spectroscopy (FTIR) and Nuclear Magnetic Resonance analysis indicate that the bio oil expressed a lower H/C ratio, higher O content and more light components including liquid compounds comparing to the petroleum asphalt. The content of the polar group including O-H and C-O of bio oil was higher than that of petroleum asphalt. Gas Chromatography-Mass Spectrometry (GC-MS) was used to prove the presence of olefins and alcohols in bio oil. Thermogravimetric analysis showed that the bio oil expressed better thermal stability than that of petroleum asphalt, which expressed a potential of using as a pavement material. The dynamic shear rheometer (DSR) results showed that the complex shear modulus, G* decreased as the content of bio oil. The Glass transition temperature Tg indicated that the bio asphalt with 10% bio oil content showed similar performance with that of 70# asphalt. (C) 2020 Published by Elsevier Ltd.
