Abstract
The aim of cross-sectional study was to investigate the association between pain and loneliness and increased social isolation during the COVID-19 pandemic. A total of 25,482 participants, aged 15–79 years, were assessed using an internet survey; the University of California, Los Angeles Loneliness Scale (Version 3), Short Form 3-item (UCLA-LS3-SF3) was used to assess loneliness, and a modified item of the UCLA-LS3-SF3 was used to measure the perception of increased social isolation during the pandemic. The outcome measures included the prevalence/incidence of pain (i.e., headache, neck or shoulder pain, upper limb pain, low back pain, and leg pain), pain intensity, and chronic pain history/prevalence. Pain intensity was measured by the pain/discomfort item of the 5-level version of the EuroQol 5 Dimension scale. Odds ratios of pain prevalence/incidence and chronic pain history/prevalence according to the UCLA-LS3-SF3 scoring groups (tertiles) and the frequency of the perceived increase in social isolation (categories 1–5) were calculated using multinomial logistic regression analysis. The mean pain intensity values among different loneliness and social isolation levels were tested using an analysis of covariance. Increased loneliness and the severity of the perceived social isolation were positively associated with pain prevalence/incidence, intensity, and the history/prevalence of chronic pain.

Abstract
Background: While the suicide rate in Japan has recently declined, it is still high from a global perspective. Recently, suicides related to unemployment caused by COVID-19 have increased. In addition, because of increases in karoshi and industrial accidents, mental health measures for workers have become an urgent issue. We previously conducted a study that tested whether screening for mood disorders, which were strongly associated with suicide-related behavior, helps prevent suicide in small and medium-size enterprise workers, where mental health support was insufficient. The current study builds on 2 the previous study’s findings that mental illness screening helps identify mood disorders and may provide a primary prevention method for suicide. Methods: A total of 1,411 consenting workers were surveyed using the Mini-International Neuropsychiatric Interview (MINI). A representative module of each disease item was extracted and analyzed. The Center for Epidemiological Studies-Depression (CES-D), Bipolar Spectrum Diagnostic Scale (BSDS), Liebowitz Social Anxiety Scale (LSAS-J), and the Sheehan Disability Scale (SDISS) were used as secondary assessments. We compared individuals with depression, bipolar disorder, dysthymia, and mood disorders with a control group. In addition, we conducted multivariate analyses to investigate items that identified individuals with depression, mood dysregulation, bipolar disorder, or all-inclusive mood disorders. Results The adjusted odds ratios in the anxiety disorders groups were 3.2 for panic disorder, 2.6 for social anxiety disorder, 2.1 for agoraphobia, and 1.8 for generalized anxiety disorder; 2.1 for obsessive compulsive disorders; and 2.8 for the bulimia nervosa group. These results show a significant correlation with mental illnesses that are referred to as neuroses in a conventional diagnosis. Conclusion: The study found that screening for anxiety disorders, obsessive-compulsive disorders and eating disorders contributes to preventing mood disorders among workers. We hope that our findings will indirectly contribute to preventing workers’ suicides.

Abstract
BackgroundAnastomotic leakage is the most serious and unwelcome complication in rectal surgery. It has a great impact on postoperative morbidity and mortality. In this pilot study changes of mRNA expression in blood were analyzed in an animal model designed to imitate anastomotic leakage.Materials and MethodsTwelve pigs were randomized into two groups. A control group and an experimental group, there an iatrogenic rectal perforation was performed. The changes in the mRNA expression were studied four hours after the perforation. Microarray analysis was performed using the Gene Chip whole porcine genome array.Results19 124 mRNA genes were investigated. Significantly increased levels of genes with a fold change (FC) over 2 were found, including 276 genes coding for an unknown protein and 48 mRNA coded for a known protein. Eleven of the genes which coded for a known protein were highly up-regulated with an FC >4.ConclusionEleven known genes were consistently up-regulated after the rectal perforation. These genes were mainly involved in inflammatory response, intracellular signaling and cell membrane regulation. Their corresponding proteins could potentially be clinical biomarkers of anastomotic leakage and should be evaluated in further clinical studies.

Abstract
Light is an essential environmental cue that determines the overall growth and development of plants. However, the molecular mechanisms underpinning the light signaling network are obscured by the epigenetic machinery where reversible acetylation and deacetylation play crucial roles in modulating light-regulated gene expression. In this paper, we demonstrate that HDA15 represses COP1, the master switch in the light signaling network, by deacetylation, protein interaction, and sub-compartmentalization. hda15 T-DNA mutant lines exhibited light hyposensitivity with significantly reduced HY5 and PIF3 transcript levels leading to long-hypocotyl phenotypes in the dark while its overexpression exhibited elevated HY5 transcripts and short hypocotyl phenotypes. In vivo and in vitro binding assays further show that HDA15 directly interacts with COP1 inside the nucleus modulating COP1’s repressive activities. Crossing hda15-t27 with cop1-4 mutants resulted in short-hypocotyl and dwarfed phenotypes, reminiscent of cop1-4 mutants suggesting COP1 is epistatic to HDA15. Although light signals the nucleocytoplasmic shuttling of HDA15, the presence of COP1 triggers its nuclear localization. A working model is presented elucidating the concerted interplay between HDA15 and COP1 under light and dark conditions.

Abstract
Chrome tanning is one of the popular tanning methods followed globally that generates considerable level of chromium pollution in the resulting effluent. The existing conventional chrome tanning system has to be modified to increase the exhaustion level of chromium in the tanning process. In the present investigation, a protein based product has been developed from raw trimming wastes and applied in chrome tanning process to enhance the exhaustion level of chromium. The experiment conducted using the product at the level of 6% exhibited chromium exhaustion at the level of 93% in the process. FT-IR analysis revealed the presence of peaks for various functional groups namely carboxylic acids, aldehyde, amide and hydroxyl groups for the high exhaust chrome tanning. The shrinkage temperature of the experimental leather was found to be more than 100 o C. Results of microscopic studies from SEM-EDX revealed that enhanced adsorption of chromium up to a level of 5.24 weight % containing chromium with atomic % 1.27 in the sample of 6% co-polymer. AFM images also show increase in adsorption of chromium with increased amount of co-polymer in the solution. Increased interactions between active sites of collagen-complex and chromium resulted into improved exhaustion of chromium as revealed from higher intensities of XRD images. CD spectra revealed that the addition of protein based product increased the ellipticity of the collagen in the experimental sample as compared to control sample. The crust leather showed improved colour, organoleptic and comparable strength properties of the experimental leather.

Abstract
Background: A key component of caring for service users (SUs) in acute mental health inpatient environments is Therapeutic Engagement (TE). To that end, the Therapeutic Engagement Questionnaire (TEQ) was developed and validated. The TEQ measures TE between SUs and registered mental health nurses (RMHNs) from the perspective of both parties and can quantify and recognise how nurses engage with SUs and monitor this activity as well as its enhancement of SU care and recovery. The aim of this study was to explore the views of SUs and RMHNs in relation to the TEQ and how it could be adopted into clinical practice within an acute inpatient environment.Methods: As part of the validation stage of the development of the TEQ, the views of 628 SUs and 543 RMHNs were collected using a qualitative approach by way of free text at the end of the questionnaire. Two questions required free text response: – ‘what do you think of the TEQ?’, and ‘how can it be utilised?’Results: Following thematic analysis, it was found that both sets of participants stated that such a tool could be utilised to improve the service, could help nurses with reflective practice, be utilised as part of clinical supervision and to aid nurses’ professional development. The nurse participants also stated that such a tool would help track SU participation and enablement in their care. Furthermore, the nurses noted that the tool would help to reinforce the core ‘caring’ value of nursing and the overall goal of recovery. The SUs added that a TE tool would recognise the work of mental health nurses and provide them with a clear opportunity to express their views in relation to nursing staff.Conclusions: Therapeutic engagement (TE) has been identified as part of the repertoire of mental health nursing and both groups of participants identified how a tool to assess this construct may be utilised in day-to-day clinical practice to the benefit of each group.

Published: March 2021

Abstract
The present research aimed at investigating zinc (Zn) sorption capacity of the biochars derived from apple wood (WB) and rice straw (RB) feedstocks at two 300 and 600°C pyrolysis temperatures (WB300, WB600, RB300 and RB600, respectively) in aqueous solutions. Kinetic and equilibrium sorption experiments were conducted via batch technique. In equilibrium adsorption experiments, the study used the concentration range of 5-200 mg Zn L− 1 and focused on the solution pH effect on Zn adsorption in biochars under the following conditions: unadjusted and adjusted pH (4 and 6) and three ionic strength levels (0.01, 0.03, 0.1 M KNO3). Zinc desorption experiments were conducted under all above mentioned conditions but without pH adjustment at five separate stages. Kinetic data analysis indicated that Zn adsorption in biochars reached the near steady state within 24 hours with the sorption rate order of WB300 < WB600 < RB300 < RB600. The best fitness was superior to both Elovich and exponential rate models. Also, Zn adsorption isotherms in the studied biochars were shown to fit quite well to Langmuir, Freundlich and Dubinin-Radushkevich models. Zn sorption maxima were found to be 4.3, 16.4, 17.9 and 33.3 mg g− 1, on average, for WB300, WB600, RB300, and RB600, respectively. The initial increased pH solution from 4 to 6 caused an increase in Zn adsorption in RB600, RB300 and WB600, however the sorption maxima in WB300 was detected at pH 4. The rise in solution ionic strength from 0.01 M to 0.1 M dropped the Zn adsorption capacity in all the studied biochars. Findings suggested that rice straw derived biochars showed a better performance than woody biochars in Zn sorption and retention from aqueous solutions. In addition, this ability increased with increasing pyrolysis temperature in both types of biochars. Finally, the study revealed that rice straw biochars, produced at high pyrolysis temperatures, can serve as economical and efficient absorbents for Zn removal from aqueous solutions.

Abstract
Pregnancy comes with hormonal changes which, when not properly managed, could lead to complications. Thyroid hormone is one of the hormones that are affected during pregnancy, and it plays a significant role in pregnancy, from conception to delivery. In a bid to identify intended pregnant women and pregnant women with thyroid dysfunction, the Endocrinology Branch of Chinese Medical Association and Perinatal medicine branch of Chinese Medical Association set guidelines for diagnosis and treatment of thyroid diseases in pregnancy and postpartum women. The guideline recommends screening for all women who desire getting pregnant soon and pregnant women, which Second Affiliated Hospital of Chongqing Medical University is implementing. This study was carried out to Identify the common thyroid disease found among pregnant women in Chongqing, evaluate the effectiveness of the management guideline toward improving pregnancy outcome among women diagnosed with thyroid disease during their pregestational and gestational period, and ascertain the need for additional measures to be taken towards thyroid disease management during pregnancy in certain areas with unfavourable outcome. Our findings showed an association between maternal age and abortion among pregnant women diagnosed with subclinical hypothyroidism, P-0.018(OR 1.459, 95%CI 1.067–1.997) and significant difference in pregnant women who developed intrauterine growth restriction after being diagnosed with hypothyroidism in the second trimester, P-0.048(OR-0.152, 95%CI 0.024–0.981). There was also a significant difference in gravida, P-0.032(OR 1.368, 95%CI 1.028 1.821) and normal delivery mode, P-0.010(OR 2.521, 95%CI 1.246-5.100). The study shows a promising result as less complication is observed. However, more attention is needed toward managing subclinical hypothyroidism in pregnancy to curb abortion/miscarriage incidence. Hypothyroidism in second trimester could lead to intrauterine growth restriction. Multigravida increases the risk of complication among pregnant women with thyroid dysfunction.
Somatic genetics of CDR3 control TCR V-domain rotational probability and germline CDR2 scanning of polymorphic MHC
Authors: Murray Joseph 
Published: March 2021

Abstract
The mechanism which adapts the T-cell antigen receptor (TCR) within a given major histocompatibility complex (MHC/HLA) genotype is essential for protection against pathogens. Historically attributed to relative affinity, genetically vast TCRs are surprisingly focused towards a micromolar affinity for their respective peptide (p) plus MHC (pMHC) ligands. Thus, the somatic diversity of the TCR with respect to MHC-restriction, and (ultimately) to pathogens, remains enigmatic. Here, we derive a triple integral solution (from fixed geometry) for any given V domain in TCR bound to pMHC. Solved complexes involving HLA-DR and HLA-DQ, where genetic linkage to the TCR is most profound, were examined in detail. Certain V domains displayed rare geometry within this panel—specifying a restricted rotational probability/volumetric density (dV). Remarkably, hydrogen (H) bond charge-relays distinguished these structures from the others; suggesting that CDR3 binding chemistry dictates CDR2 contacts on the opposite MHC-II alpha helix. Together, these data suggest that TCR recapitulate dV and specialise target pMHC recognition, i.e., a dynamics alternative to a relative TCR-affinity based mechanism.

Abstract
The widely used surface-based biomolecule sensing scheme has greatly facilitated the investigation of protein-protein interactions in lab-on-a-chip microfluidic systems. However, in most biosensing schemes, the interactions are driven in a passive way: The overall sensing time and sensitivity are totally dependent on the Brownian diffusion process, which has greatly hindered their efficiency, especially at low concentration level or single-molecule analysis. To break this limitation, we developed an all-optical active method termed optothermophoretic flipping (OTF). The biomolecules were first enriched to aggregation and then pushed to their counterparts for effective contact via a flipped thermophoresis. As a proof-of-concept experiment, we tested its performance via antibody-antigen binding on a surface plasmon resonance imaging (SPRi) platform. We achieved 36.9-fold sensitivity enhancement in this first temporal modulated approach that manipulates biomolecules for interaction enhancement. This method promises to be widely adopted in various biosensing platforms that require ultrasensitivity in colloidal sciences and biochemical studies.

Abstract
Thermal treatment of mercury (Hg)-contaminated soil was studied to investigate the desorption behavior of Hg at different temperatures. The soil samples were collected from two locations with different land uses around the mine and industrial site. The effect of soil properties such as inorganic carbonate minerals and organic matter content on Hg desorption was investigated to understand the thermal desorption process. The effect of soil composition on Hg desorption showed that behavior at 100 °C was similar, but different behavior could be found at 300 °C. The thermal desorption efficiency at 300 °C is affected by the thermal properties of soils and the Hg desorption capacity of the soils. The Hg from both soil types was removed above 300 °C, and Hg was effectively removed from mine soil due to the partial decomposition of carbonate in the soil composition, while industrial soil showed that desorption would be restrained by Hg organic matter complexes due to organic matter content. Despite a relatively higher concentration of Hg in the mine soil, Hg removal efficiency was greater than that in the industrial soil. Sequential extraction results showed that only the Hg fractions (residual fractions, F6) in mine soil changed, while the industrial soil was affected by changes in Hg fractions (F3 to F6) at 300 °C. Changes in soil pH during thermal desorption are also influenced by heating time and temperature. Therefore, the mechanisms of Hg desorption during thermal treatment were observed by soil properties. The volatilization of Hg in the soil is induced by organic carbon, while soil Hg release is controlled by organic matter complexes.
The Anatomical Correlates of Abstract and Concrete Words: A meta-analytical review of whole-brain imaging studies
Authors: Bucur Madalina , Papagno Costanza 
Published: March 2021

Abstract
Several studies have investigated how abstract and concrete concepts are processed in the brain, but data are controversial, in particular neuroimaging data contrast with clinical neuropsychological observations. A possible explanation could be that previous meta-analyses considered different types of stimuli (nouns, verbs, literal and figurative sentences). Using the ALE method, we meta-analyzed 32 brain-activation imaging studies that considered only words (nouns and verbs). Five clusters were associated with concrete words (the left superior occipital, middle temporal, parahippocampal and bilateral posterior cingulate, angular, and precuneus gyri); four clusters were associated with abstract words (left IFG, superior, and middle temporal gyri). When only nouns were considered three left activation clusters were associated with concrete stimuli and only one with abstract nouns (left IFG). These results confirm that concrete and abstract word processing involves at least partially segregated brain areas, the IFG being relevant for abstract nouns and verbs while more posterior temporo-parieto-occipital regions seem to be crucial for concrete words.

Published: March 2021

Abstract
Background: Sorafenib is the first molecular-targeted drug for the treatment of advanced hepatocellular carcinoma (HCC). However, its treatment efficiency decreases after a short period of time because of the development of drug resistance. This study investigates the role of key genes in regulating sorafenib-resistance in hepatocellular carcinoma and elucidates the mechanism of drug resistance. Methods: The HCC HepG2 cells were used to generate a sorafenib-resistant cell model by culturing the cells in gradually increasing concentration of sorafenib. RNA microarray was applied to profile gene expression and screen key genes associated with sorafenib resistance. Specific targets were knockdown in sorafenib-resistant HepG2 cells for functional studies. The HCC model was established in ACI rats using Morris hepatoma3924A cells to validate selected genes associated with sorafenib resistance in vivo. Results: The HepG2 sorafenib-resistant cell model was successfully established. The IC50 of sorafenib was 9.988mM in HepG2 sorafenib-resistant cells. A total of 35 up-regulated genes were detected by expression profile chip. High-content screening technology was used and a potential drug-resistant gene RPL28 was filtered out. After knocking down of RPL28 in HepG2 sorafenib-resistant cells, the results of cell proliferation and apoptosis illustrated that RPL28 is the key drug-resistant gene in the cells. Furthermore, it was found that both RNA and protein expression of RPL28 increased in HepG2 sorafenib-resistant specimens of Morris Hepatoma rats. In addition, the expression of functional proteins Ki-67 increased in sorafenib-resistant cells. Conclusion: Our study suggested that RPL28 was a key gene for sorafenib resistance in HCC both in vitro and in vivo.
