Emerging trends in colorectal cancer: Dysregulated signaling pathways (Review)

Colorectal cancer (CRC) is the third most frequently detected type of cancer, and the second most common cause of cancer-related mortality globally. The American Cancer Society predicted that approximately 147,950 individuals would be diagnosed with CRC, out of which 53,200 individuals would succumb to the disease in the USA alone in 2020. CRC-related mortality ranks third among both males and females in the USA. CRC arises from 3 major pathways: i) The adenoma-carcinoma sequence; ii) serrated pathway; and iii) the inflammatory pathway. The majority of cases of CRC are sporadic and result from risk factors, such as a sedentary lifestyle, obesity, processed diets, alcohol consumption and smoking. CRC is also a common preventable cancer. With widespread CRC screening, the incidence and mortality from CRC have decreased in developed countries. However, over the past few decades, CRC cases and mortality have been on the rise in young adults (age, <50 years). In addition, CRC cases are increasing in developing countries with a low gross domestic product (GDP) due to lifestyle changes. CRC is an etiologically heterogeneous disease classified by tumor location and alterations in global gene expression. Accumulating genetic and epigenetic perturbations and aberrations over time in tumor suppressor genes, oncogenes and DNA mismatch repair genes could be a precursor to the onset of colorectal cancer. CRC can be divided as sporadic, familial, and inherited depending on the origin of the mutation. Germline mutations in APC and MLH1 have been proven to play an etiological role, resulting in the predisposition of individuals to CRC. Genetic alterations cause the dysregulation of signaling pathways leading to drug resistance, the inhibition of apoptosis and the induction of proliferation, invasion and migration, resulting in CRC development and metastasis. Timely detection and effective precision therapies based on the present knowledge of CRC is essential for successful treatment and patient survival. The present review presents the CRC incidence, risk factors, dysregulated signaling pathways and targeted therapies. Interested yet?

Polyoxometalate-Ionic Liquids (ILs) and Polyvinyl Alcohol/Chitosan/ILs Hydrogels for Inhibiting Bacteria Colonising Wall Paintings

Historical monuments are increasingly being threatened by unexpected microbial colonizers, leading to their subsequent deterioration. Here, two tetraalkylphosphonium polyoxometalate ionic liquids (Q14-IL and Q16-IL) were successfully synthesized, which showed excellent antibacterial activity against four bacteria colonising wall paintings. Notably, Q14-IL exhibited superior antibacterial efficacy compared to longer alkyl Q16-IL. Additionally, polyvinyl alcohol/chitosan (PVA-CS) hydrogels containing two ILs were prepared, and the morphology, thermal stability, swelling ratio and antibacterial activity were systematically evaluated. The results suggest that higher CS content resulted in more uniform micropores and increased the swelling ratio. However, fewer antibacterial ILs were released and diffused over time from the matrix. Hydrogels with 5% CS content exhibited the highest antibacterial activity, which was mainly attributed to the synergetic antibacterial activity of positively charged ammonium (-NH3+) groups of CS and quaternary phosphonium cation of ILs. This study may provide an alternative strategy for fighting against bacterial communities colonising ancient artworks.

Enhanced flux and fouling resistance forward osmosis membrane based on a hydrogel/MOF hybrid selective layer

Although forward osmosis (FO) technology has been widely adopted for water treatment, it still faces great challenges, including low permeability and fouling problem. Herein, a novel forward osmosis membrane was developed with a stable, uniform and defect-free polyvinyl alcohol/polydopamine coated zeolitic imidazolate framework (PVA/PDA@ZIF-8) hybrid selective layer to simultaneously enhance its transport property and fouling resistance. The prepared FO membrane exhibits improved water flux without losing the selectivity, since the PDA@ZIF-8 provide additional preferential passageway for water transporting while hinder the diffusion of salt. The optimized membrane shows a higher water flux than pristine PVA membrane (14.2 vs. 8.7 L m(-2) h(-1) in FO mode, 24.3 vs. 14.8 L m(-2) h(-1) in PRO mode) with a reasonable selectivity considering as J(s)/J(w) value (0.44 vs. 0.4 g L-1 in FO mode, 0.38 vs. 0.33 g L-1). Moreover, the dynamic fouling experiments with organic foulants (protein and polysaccharide) indicate that the prepared membrane exhibits strong antifouling property and excellent permeation recovery ability (>95.0%) due to the optimized surface property. This study opens a new avenue for treatment wastewater by developing a forward osmosis membrane based on a hydrogel/MOF hybrid selective layer. (C) 2020 Elsevier Inc. All rights reserved.

Effective degradation of tetracycline via polyvinyl alcohol /Bi2WO6 hybrid hydrogel with easy separation

Developing inexpensive and stable photocatalysts with easy separation for the degradation of antibiotics is highly needed. In this study, a three-dimensional poly(vinyl alcohol) (PVA)/Bi2WO6 (BWO) (PVA/BWO) hybrid hydrogel photocatalyst with easy separation was constructed via freeze-thaw process and then was used to remove Tetracycline (TC) from water. The obtained hydrogels were characterized by various techniques. SEM image and EDS mapping show the successful decoration of BWO and the BWO is homogenously distributed on the PVA substrate. Results of the photocatalytic experiment and total organic carbon content (TOC) measurement show that the constructed PVA/BWO hydrogel could degrade TC effectively under visible light irradiation, even after the PVA/BWO hydrogel had been recycled for five times. Results of XRD, SEM and EDS mapping on the fresh and used PVA/BWO hydrogel confirm its relatively good stability in structure. The possible reaction pathways and mechanism of TC degradation were also analyzed. The PVA/BWO hybrid hydrogel with easy separation could be a new alternative with great potential in efficient removal of persistent organic pollutants.

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.

The association between reinforcement sensitivity and substance use is mediated by individual differences in dispositional affectivity in adolescents

Background: Adolescence marks the onset of substance use experimentation and adolescents are particularly vulnerable to certain negative effects of substances. Some evidence indicates reinforcement sensitivity is associated with substance use, though little is known about mechanisms underlying such association. Aims: in the current study were to examine, (1) associations between behavioral activation (BAS) and behavioral inhibition (BIS) system sensitivity, positive (PA) and negative affectivity (NA), and alcohol use and alcohol problems as well as tobacco, and marijuana use, and whether (2) associations are mediated by PA or NA. Methods: Participants were a community sample of N = 125 adolescents (M-age = 15.67 years; SD = 0.93; 52% boys) who completed self-report measures. Results: evinced associations, generally as expected, across variables (all ps < 0.05). In mediation analyses, an association emerged between BIS sensitivity and alcohol use, mediated by NA (95%CIs [0.034; 0.390]); greater BIS sensitivity was associated with greater NA and greater NA was associated with greater alcohol use. These findings were replicated with alcohol problems. An association also emerged between BAS sensitivity and marijuana use, mediated by PA (95%CIs [-0.296; -0.027]); greater BAS sensitivity was associated with greater PA and greater PA was associated with lower marijuana use. Finally, BIS sensitivity was associated with tobacco use through NA (95%CIs [0.023; 0.325]) and PA (95%CIs [0.004; 0.116]), with NA linked to greater, but PA linked to lower tobacco use. BAS sensitivity was also associated with tobacco use through PA (95%CIs [-0.395; -0.049]), with PA linked again to lower tobacco use. Conclusions: There are unique and shared effects of domains of reinforcement sensitivity on adolescent substance use and these vary with index of dispositional affectivity and type of substance considered.

Persulfate activation by ZIF-67-derived cobalt/nitrogen-doped carbon composites: Kinetics and mechanisms dependent on persulfate precursor

Whereas previous studies that explored the application of metal-carbon composites as persulfate activators have focused on synergistic performance improvements, the potential advantages or features that can be acquired by integrating metal and carbon constituents that differ in terms of reactivity toward persulfate precursors and their preferred activation routes have been overlooked. With ZIF-67-derived cobalt/N-doped carbon composites (Co@N-C) as the model metal-carbon composite, this study takes a look into a switch in the primary degradative pathway depending on the persulfate precursor used and investigates this kind of composite fabrication as a strategy to overcome the drawbacks of single-component activators. In Co@N-C, Co embedded in the carbon matrix caused radical-induced oxidation in the presence of peroxymonosulfate (PMS) whereas peroxydisulfate (PDS) activation using a carbon framework involved mediated electron transfer. The different nature of the dominant oxidant was confirmed by investigating the quenching effects of alcohols, bromate formation yield, substrate-specificity, electron paramagnetic resonance spectral features, current generation upon sequential organic and persulfate injection, and product distribution. The Co and N-doped carbon serving as separate reactive sites allowed Co@N-C to exploit both PMS and PDS so it could outperform benchmark metaland carbon-derived materials. Electrochemical measurements linked with X-ray spectroscopic analysis implied that a moderate pyrolysis temperature optimized the Co@N-C activity due to high fractions of graphitic N and Co-N species. Density functional theory calculations reveal that the peroxide bond of PMS is more susceptible to elongation over Co@N-C, thus it is preferentially dissociated to yield sulfate radicals.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 13325-10-5. Recommanded Product: 13325-10-5.

A new approach for producing mid-ethanol fuels E30 based on low-octane hydrocarbon surrogate blends

Development of mid-ethanol fuel with an ethyl alcohol content of 20-40% (E30 fuel), which is devoid of phase instability problems and can potentially be applied to automotive technology without modifications, and it is a promising area. One of the promising ways is to develop high-octane E30 fuel based on cheap low-octane fractions, which will significantly improve the economic parameters of fuel production. This research paper investigates the influence of bioethanol at a concentration of 5-85 wt% on the change in an antiknock performance of low-octane hydrocarbon fractions, involving heavy hydrocracked naphtha and straight run hydrotreated naphtha, as well as low-octane surrogate blends of individual hydrocarbons of various groups, containing n-heptane, isooctane, toluene, p-xylene, cyclohexane, n-pentane, n-hexane, and isooctene. The results indicated that the antiknock performance of bioethanol in low-octane hydrocarbon fractions was increased in the series: olefins Computed Properties of C4H11NO.

Effects of chemogenetic manipulation of the nucleus accumbens core in male C57BL/6J mice

Binge drinking is a widespread public health concern with limited effective treatment options. To better select pharmaceutical targets, it is imperative to expand our knowledge of the underlying neural mechanisms involved in binge drinking. Our previous experiments in C57BL/6J female mice found that increasing activity in the nucleus accumbens (NAc) core using excitatory Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) reduced binge-like drinking. These results differed from what has been found in males; however, it is unclear whether differences in experimental procedures or sex underlie these discrepancies. We matched the conditions used in our female study and asked whether bidirectional manipulation of NAc core activity has different effects on binge-like drinking in males. Male C57BL/6J mice were stereotaxically injected with AAV2 hSyn-HA hM3Dq (excitatory), -hM4Di (inhibitory), or -eGFP bilaterally into the NAc core. We tested the effects of altering NAc activity on binge-like ethanol intake using Drinking in the Dark (DID). During the first week, mice were pre-treated with vehicle to establish baseline ethanol intake. In week 2, mice were treated with 1 mg/kg CNO prior to DID to determine the effects of DREADD-induced changes in NAc core activity on ethanol intake. Decreasing activity via CNO/hM4Di significantly decreased binge-like drinking in male mice relative to eGFP and hM4Di groups. We also measured intake of sucrose, quinine, and water after CNO treatment and found that increasing NAc core activity via CNO/hM3Dq increased quinine intake, and increased water intake over time. We did not observe significant differences in the GFP or hM4Di groups. This work suggests there exist apparent sex-related differences in NAc core contributions to binge-like alcohol drinking, thus demonstrating the need for inclusion of both sexes in future work.

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.
