Authors:   , Boonyakarn Tat 
Published: November 2023

The production of 5-hydroxymethylfurfural (HMF) and levulinic acid (LA) from cellulose is gaining considerable interests as these compounds are suitable starting materials for the preparation for valuable compounds. This study proposes a novel catalysis system, the combination of hydrothermal carbon based acid catalyst (HTCG-Sul) and Lewis acid, for the synergistic one-pot conversion of cellulose to HMF and LA. The CrCl3 (Chromium chloride) Lewis acid, when used alone was a suitable catalyst for cellulose conversion, giving highest HMF and LA yields compared with other metal chloride catalysts. When CrCl3 was combined with HTCG-Sul, the results showed that approximately 2 times higher of HMF (6.8 wt. % vs. 3.9 wt. %) and LA (22.9 wt. % vs. 11.2 wt. %), yields were obtained. Using combination of HTCG-Sul and CrCl3 as catalyst, the effect of operating conditions: including reaction temperature (160oC - 220oC), reaction time (0 - 60 min), CrCl3 concentration (0 - 0.02 molar) and HTCG-Sul dosage (0 – 40 wt. %) on cellulose conversion was studied first in a single phase reaction system. At the condition HTCG-Sul dosage of 5 wt. %, temperature of 200oC, reaction time of 5 min and CrCl3 concentration of 0.005 molar), the highest HMF yield of 6.8 wt. % operating conditions of the highest LA yield was found however at a different condition: HTCG-Sul dosage 5 wt. %, 200oC for 5 min and 0.015 molar CrCl3 concentration, which gave 40 wt. % LA yield. Furthermore, a biphasic system using methyl isobutyl ketone (MIBK)/2-butanol (7:3) as an extractive phase, water as a reactive phase, and acetone as a co-solvent and the combination of HTCG-Sul and CrCl3 as catalyst was employed to improve the stability and the yield of HMF (17.7 wt. %).

Published: November 2023

Six azobenzene-diaza-18-crown-6 derivatives were synthesized and characterized by 1H, 13C-NMR, and mass spectroscopies. The three ester derivatives E1, E2 and EE2 did not show any special sensing property towards any metal ion. Acid and nitro derivatives showed solvatochromic effects and dependent sensing properties in various solvents. The acid derivative A2 displayed inseparable color yellow or green from orange upon addition of transition and heavy metal ions in DMSO which, unfortunately, could not be used as optical chemosensor. In contrast, the nitro derivatives N1 and N2 showed selectivity toward Cr3+ in MeCN by color changing from pink to colorless with a blue shift of 125 and 165 nm, respectively. Both sensors form complex ML2 and ML with Cr3+​ in MeCN. Hg2+ also induced a large blue shift around 160 nm in the UV-Visible spectra of N1 and N2 in DMSO with color change from purple to colorless. The value of log K for ML complex of N2 with Hg2+ is equal to 5.97. The naked eye detection limit towards target ions are 0.09 and 0.27 ppm for N1 and N2 for Cr3+ in MeCN, and 0.90 and 1.40 ppm for N1 and N2 for Hg2+ in DMSO. This low detection limit for Cr3+ could be used to monitor Cr3+ that bring acute toxic to aquatic life. Furthermore, N1 and N2 showed selectivity towards F– and in both MeCN and DMSO: F– could induce a color change of N1 from pink to purple in MeCN and from purple to blue in DMSO as a result of a red shift of 50-60 nm. H2PO4- also induced a color change from pink or purple to colorless with a 130-160 nm blue shift. Thus N1 and N2 could be potentially employed as chromogenic sensors for both metal ions such as Cr3+ and Hg2+ and anions like F– and H2PO4-.

Published: November 2023

Adsorptions of small gases and their reactions on modified anatase TiO2 (001) as ZnOSL supported on anatase TiO2 (001), (ZnOSL/TiO2), and Mn–doped TiO2 (001) surfaces have been studied by density functional theory (DFT) method. The calculation models relied on both of clusters and periodic boundary conditions (PBCs). It was found that Ti5C and O2c sites on anatase TiO2 (001) are active for ZnOSL supporting. The conversion of carbon monoxide by oxygen forming carbon dioxide gas over the ZnOSL/TiO2 composite was studied. Moreover, ZnOSL, transition metals, and non–metals doped–ZnOSL clusters have studied to understand the properties of their surfaces. Resulting from the study of small gases on the Sc–ZnOSL, the most stable adsorption configuration is SO2 adsorption. The most decreasing of energy gap for N2O bridge–structured adsorption on Sc–ZnOSL was found. The Sc–ZnOSL used as N2O or SO2 sensing material was suggested. For the system of Mn–doped anatase (001) surface, Mn–doped anatase (001) surface enhances the activity of O2 pre–adsorption and CO adsorption for CO to CO2 conversion. Therefore, the results indicate that modified anatase (001) surface can be used for the conversion of carbon monoxide by oxygen gas forming carbon dioxide gas reaction.

Objectives
We aimed to estimate the genotype distribution of persistent human papillomavirus (HPV) infection in females worldwide, and provided a scientific basis for the prevention strategies of cervical cancer (CC) and the development of HPV vaccines.

Methods
Both English and Chinese databases were researched from the inception to July 2023. The pooled persistent HPV infection prevalence was calculated using a random effects model. The subgroup analysis was performed to explore the heterogeneity. Publication bias was evaluated using funnel plot, Egger’s and Begg’s test.

Results
Twenty-eight studies with 27,335 participants were included. The pooled prevalence of persistent HPV infection was 29.37% (95% CI [24.05%∼35.31%]), and the genotypes with the persistent infection prevalence were HPV16 (35.01%), HPV52 (28.19%), HPV58 (27.06%), HPV18 (25.99%), HPV33 (24.37%), HPV31 (23.35%), HPV59 (21.87%), HPV39 (19.54%), HPV68 (16.61%) and HPV45 (15.05%). The prevalence of multiple and single HPV persistent infection were 48.66% and 36.71%, respectively; the prevalence of persistent HPV infection in different age groups (<30, 30∼39, 40∼49, >50) were 29.83%, 28.39%, 22.24% and 30.22%, respectively. The follow-up time was significantly associated with heterogeneity by subgroup analysis (P < 0.05), and the prevalence of persistent infection decreased with longer follow-up time.

Conclusions
Multiple infections were more likely to occur persistent HPV infection than single infection. In addition to HPV vaccination, we should emphasize the follow-up management for women under 30 and over 50 years old, those with high-risk HPV infection (HPV59, 39, 68) and multiple infections.
Tricks of the puppet masters: morphological adaptations to the interaction with nervous system underlying host manipulation by rhizocephalan barnaclePolyascus polygeneus

Published: November 2023

BackgroundRhizocephalan interaction with their decapod hosts is a superb example of host manipulation. These parasites are able to alter the host’s physiology and behavior. Host-parasite interaction is performed, presumably,viaspecial modified rootlets invading the ventral ganglions.MethodsIn this study, we focus on the morphology and ultrastructure of these special rootlets inPolyascus polygeneus(Lützen & Takahashi, 1997), family Polyascidae, invading the neuropil of the host’s nervous tissue. The ventral ganglionic mass of the infected crabs were fixed, and the observed sites of the host-parasite interplay were studied using transmission electron microscopy, immunolabeling and confocal microscopy.ResultsThe goblet-shaped organs present in the basal families of parasitic barnacles were presumably lost in a common ancestor of Polyascidae and crown “Akentrogonida”, but the observed invasive rootlets appear to perform similar functions, including the synthesis of various substances which are transferred to the host’s nervous tissue. Invasive rootlets significantly differ from trophic ones in cell layer composition and cuticle thickness. Numerous multilamellar bodies are present in the rootlets indicating the intrinsic cell rearrangement. The invasive rootlets ofP. polygeneusare enlaced by the thin projections of glial cells. Thus, glial cells can be both the first hosts’ respondents to the nervous tissue damage and the mediator of the rhizocephalan interaction with the nervous cells. One of the potential molecules engaged in the relationships ofP. polygeneusand its host is serotonin, a neurotransmitter which is found exclusively in the invasive rootlets but not in trophic ones. Serotonin participates in different biological pathways in metazoans including the regulation of aggression in crustaceans, which is reduced in infected crabs. We conclude that rootlets associated with the host’s nervous tissue are crucial for the regulation of host-parasite interplay and for evolution of the Rhizocephala.
Psychometric properties of the Mexican version of the opening minds stigma scale for health care providers (OMS-HC)

Published: November 2023

Background
Healthcare providers are one of the main groups that contribute to the stigmatization of people with mental disorders. Apathy, accusation, fatalism, and morbid curiosity are the most common forms of stigmatization encountered, and these are associated with inadequate treatment, reduced treatment adherence, decreased help-seeking behavior, an increased risk of relapse, and complications with other medical conditions. The aim of this study was to examine the psychometric properties of an adapted Spanish version of the Opening Minds Stigma Scale (OMS-HC) for healthcare providers in Mexico and identify certain stigmatizing attitudes within this group.

Methods
An ex-post facto cross-sectional observational study was conducted with 556 healthcare providers in Mexico, with an average age of 29.7 years, who were mostly women (80.4%). Validity was examined through confirmatory factor analysis. Differences according to gender, discipline, occupation, and educational level were analyzed using multivariate methods.

Results
The factor structure of the OMS-HC, consisting of three subscales identified by the original authors of the instrument (attitudes of healthcare providers towards people with mental illness, secrecy/help-seeking, and social distance), was confirmed. The model demonstrated good fit (x2/df = 2.36, RMSEA = 0.050, CFI = 0.970, TLI = 0.962, SRMR = 0.054, NFI = 0.950, PNFI = 0.742). Internal consistency was found to be adequate (α = 0.73, ω = 0.76) for the scale itself and slightly lower than acceptable for the subscales. Significant differences were found by discipline, educational level, and, for student providers, by academic semester. Higher scores were observed on the OMS-HC scale among nursing and medical professionals, undergraduate students, and those in early semesters.

Conclusions
The Spanish version of the OMS-HC has demonstrated adequate psychometric properties and could be a useful tool to facilitate research on this topic in Mexico, and to carry out comparative studies with healthcare personnel in other Spanish-speaking countries.

Aims: The aim of the current study was to determine antimicrobial susceptibility patterns and the incidence of resistance genes (β-lactamase-encoded genes) among clinical isolates of K. pneumoniae.
Study Design: Investigative.
Place and Duration of Study: Department of Microbiology, Nasarawa State University, Keffi, between November 2022 and July 2023.
Methodology: A total of 375 clinical samples were randomly collected from patients and isolation and identification was done using standard microbiological methods. The antibiotic susceptibility testing for the isolates was carried out in accordance with the Clinical and Laboratory Standards Institute protocol. The detection of extended-spectrum beta-lactamase (ESBL) production in K. pneumoniae isolates was carried out using double disc synergy test. In addition, molecular detection of ESBL genes was carried out using Polymerase Chain Reaction (PCR) method.
Results: The overall incidence rate of K. pneumoniae in the 375 clinical samples from Nasarawa South Senatorial District was 38 (10.13%). Resistance was high to ampicillin (94.74%) and amoxicillin-clavulanic acid (73.6%) but low to cefotaxime (13.16%), ceftriaxone (18.42%), ceftazidime and cefoxitin (23.60%) and gentamicin (28.94%). Most of the isolates were multi-drug resistant (MDR; 81.5%) and none was Pan Drug resistant. All 15 isolates jointly resistant to cefotaxime and/or ceftazidime and ciprofloxacin 100.0% were ESBL producers, distributed as follows: blaCTX-M-1 7(46.6%); blaCTX-M-34(26.6%); blaSHV 6(40.0%); blaTEM6 (40.0%); and blaOXA 5(33.3%).
Conclusion: K. pneumoniae isolated from the urine of patients attending public hospitals in Nasarawa South were less resistant to cefotaxime, ceftazidime, gentamicin, ceftriaxone, and cefoxitin in the study location. This implies that the antibiotics are useful in the treatment of infection caused by K. pneumoniae. Also, ESBL-positive K. pneumoniae isolates harbored ESBL genes, with blaCTX-M as the most common.

ImportanceIndustry involvement is prominent in influential clinical trials, and commitments to transparency of trials are highly variable.ObjectiveTo evaluate the modes of industry involvement and the transparency features of the most cited recent clinical trials across medicine.Design, Setting, and ParticipantsThis cross-sectional study was a meta-research assessment including randomized and nonrandomized clinical trials published in 2019 or later. The 600 trials of any type of disease or setting that attracted highest number of citations in Scopus as of December 2022 were selected for analysis. Data were analyzed from March to September 2023.Main Outcomes and MeasuresOutcomes of interest were industry involvement (sponsor, author, and analyst) and transparency (protocols, statistical analysis plans, and data and code availability).ResultsAmong 600 trials with a median (IQR) sample size of 415 (124-1046) participants assessed, 409 (68.2%) had industry funding and 303 (50.5%) were exclusively industry-funded. A total of 354 trials (59.0%) had industry authors, with 280 trials (46.6%) involving industry analysts and 125 trials (20.8%) analyzed exclusively by industry analysts. Among industry-funded trials, 364 (89.0%) reached conclusions favoring the sponsor. Most trials (478 trials [79.7%]) provided a data availability statement, and most indicated intention to share the data, but only 16 trials (2.7%) had data already readily available to others. More than three-quarters of trials had full protocols (482 trials [82.0%]) or statistical analysis plans (446 trials [74.3%]) available, but only 27 trials (4.5%) explicitly mentioned sharing analysis code (8 readily available; 19 on request). Randomized trials were more likely than nonrandomized studies to involve only industry analysts (107 trials [22.9%] vs 18 trials [13.6%]; P = .02) and to have full protocols (405 studies [86.5%] vs 87 studies [65.9%]; P &amp;lt; .001) and statistical analysis plans (373 studies [79.7%] vs 73 studies [55.3%]; P &amp;lt; .001) available. Almost all nonrandomized industry-funded studies (90 of 92 studies [97.8%]) favored the sponsor. Among industry-funded trials, exclusive industry funding (odds ratio, 2.9; 95% CI, 1.5-5.4) and industry-affiliated authors (odds ratio, 2.9; 95% CI, 1.5-5.6) were associated with favorable conclusions for the sponsor.Conclusions and RelevanceThis cross-sectional study illustrates how industry involvement in the most influential clinical trials was prominent not only for funding, but also authorship and provision of analysts and was associated with conclusions favoring the sponsor. While most influential trials reported that they planned to share data and make both protocols and statistical analysis plans available, raw data and code were rarely readily available.

AbstractEndovascular embolization using microcoils can be an effective technique to treat artery aneurysms. However, microcoils with fixed designs are difficult to adapt to all aneurysm types. In this paper, a photocurable ultratough shape memory organogel with a curing time of only 2 s and megapascal‐level mechanical properties is proposed. Then, it is used to manufacture the personalized 4D microcoil with a wire diameter of only 0.3 mm. The improved mechanical modulus (511.63 MPa) can reduce the possibility of microcoils’ fracture during embolization. Besides, the fast body‐temperature‐triggering shape memory ability makes the 4D microcoil applicable in vivo. These 4D microcoils are finally delivered into the rabbit, and successfully blocked the blood flow inside different aneurysms, with neoendothelial cells and collagen fibers growing on the microcoil surface snugly, indicating full aneurysm recovery. This 4D organogel microcoil can potentially be used in personalized clinical translation on human beings.
