Technical examination of Liu Kang’s Paris and Shanghai painting supports (1929–1937)
Authors: Lizun Damian , Kurkiewicz Teresa , Szczupak Bogusław 
Published: March 2021

Abstract
This article presents an overview of Liu Kang’s (1911–2004) canvas painting supports from his early artistic phases, Paris (1929–1932) and Shanghai (1932–1937). The research was conducted on 55 artworks from the collections of the National Gallery Singapore and Liu family. The technical examination of the paintings was supplemented with archival photographs of the artist at work to elucidate his practice of preparation of painting supports. The analyses conducted with light microscopy, SEM–EDS, and FTIR allowed us to characterise the structure of the canvases and identify the natural fibres and formulation of the grounds. In addition, references to contemporary colourmen catalogues, in relation to certain materials, were made. The obtained results suggest that, in both locations, Liu Kang employed commercially prepared canvases purchased by the roll or by the metre, together with bare strainers or stretchers of standard sizes. In Paris, the artist commonly used linen canvases, while in Shanghai he preferred cotton canvases, with linen used sporadically. The identified grounds from the Paris and Shanghai canvases are white and single-layered, but their formulations vary significantly between the two locations. Hence, grounds composed predominantly of lead white with extenders and drying oil as a binder are considered as exclusive to the Paris phase. However, semi-absorbent or absorbent grounds based on chalk are typical for Shanghai phase. This research contributes to the knowledge of Liu Kang’s painting materials and working practices during the pre-war period in Paris and Shanghai.

Published: March 2021

Abstract

The treatment of irreparable rotator cuff tears with severe muscle atrophy and fatty infiltration remains a challenge, especially in young patients. Many surgical procedures for these tears have been reported. No one surgical treatment has proven to be an optimal solution. Recently, reconstruction of the superior capsule with an allograft or autograft has gained popularity. In this manuscript, we reviewed the biomechanical and clinical reports that have assessed superior capsular reconstruction and clarified the issues about the surgical techniques and indication which have been discussed recently. Reconstruction of the superior capsule has shown promising early results with good clinical outcomes. Biomechanical studies have suggested various mechanisms of this procedure. Although good clinical results and biomechanical data are available, more research is necessary to further define the surgical indications and improve the surgical outcomes of this procedure.

MAML1: a coregulator that alters endometrial epithelial cell adhesive capacity
Authors: Zafir Sadaf , Zhou Wei , Menkhorst Ellen , Santos Leilani , Dimitriadis Evdokia 
Published: March 2021

Abstract
Background
Abnormalities in endometrial receptivity has been identified as a major barrier to successful embryo implantation. Endometrial receptivity refers to the conformational and biochemical changes occurring in the endometrial epithelial layer which make it adhesive and receptive to blastocyst attachment. This takes place during the mid-secretory phase of woman’s menstrual cycle and is a result of a delicate interplay between numerous hormones, cytokines and other factors. Outside of this window, the endometrium is refractory to an implanting blastocyst. It has been shown that Notch ligands and receptors are dysregulated in the endometrium of infertile women. Mastermind Like Transcriptional Coactivator 1 (MAML1) is a known coactivator of the Notch signaling pathway. This study aimed to determine the role of MAML1 in regulating endometrial receptivity.

Methods
The expression and localization of MAML1 in the fertile human endometrium (non-receptive proliferative phase versus receptive mid-secretory phase) were determined by immunohistochemistry. Ishikawa cells were used as an endometrial epithelial model to investigate the functional consequences of MAML1 knockdown on endometrial adhesive capacity to HTR8/SVneo (trophoblast cell line) spheroids. After MAML1 knockdown in Ishikawa cells, the expression of endometrial receptivity markers and Notch dependent and independent pathway members were assessed by qPCR. Two-tailed unpaired or paired student’s t-test were used for statistical analysis with a significance threshold of P < 0.05.

Results
MAML1 was localized in the luminal epithelium, glandular epithelium and stroma of human endometrium and the increased expression identified in the mid-secretory phase was restricted only to the luminal epithelium (P < 0.05). Functional analysis using Ishikawa cells demonstrated that knockdown of MAML1 significantly reduced epithelial adhesive capacity (P < 0.01) to HTR8/SVneo (trophoblast cell line) spheroids compared to control. MAML1 knockdown significantly affected the expression of classical receptivity markers (SPP1, DPP4) and this response was not directly via hormone receptors. The expression level of Hippo pathway target Ankyrin repeat domain-containing protein 1 (ANKRD1) was also affected after MAML1 knockdown in Ishikawa cells.

Conclusion
Our data strongly suggest that MAML1 is involved in regulating the endometrial adhesive capacity and may facilitate embryo attachment, either directly or indirectly through the Notch signaling pathway.

Published: March 2021

Background/Aims Research has shown that health literacy can influence an individual's ability to practise self-care, particularly for patients with heart failure. This study aimed to assess health literacy and its relationship with heart failure knowledge and self-care practices in this patient group. Methods An observational sub-study was conducted with the data from a large randomised control trial that evaluated the relationship between patients' health literacy, general literacy, knowledge of heart failure and self-care. Results A total of 36 participants were recruited, of which 33 (89.9%) had adequate levels of health literacy. Health literacy was positively associated with heart failure knowledge. However, 67.7% of participants with adequate health literacy were found to have inadequate levels of self-care management. Conclusions Health literacy may facilitate better heart failure knowledge, but it does not necessarily lead to improved self-care management in patients with heart failure. This suggest that clinicians need to put more emphasis on translating knowledge into behavioural changes for self-care in this patient group.
Implementing a stepped-care psychological pathway for cardiac patients with comorbid anxiety and depression in the UK: a service development project
Authors: Salt Heather , El-Salahi Shama , Schiza Angeliki , Dent June 
Published: March 2021

Background/aims This was a pilot study that was part of a Department of Health and Social Care initiative to improve access to cognitive behavioural therapies for patients with long-term health conditions. The service development work involved integrating an ‘Improving Access to Psychological Therapies’ service with a cardiac rehabilitation service, to treat patients with cardiac disease and comorbid anxiety and/or depression. The aim was to reduce levels of anxiety and depression, urgent care visits, inpatient stays and outpatient appointments, and secondary care service usage. Methods A repeated-measures design was implemented using clinical data collected as part of routine practice. A quasi-control group was used for the economic evaluation, comparing patients who entered into therapy with those who did not. Collaboration between an Improving Access to Psychological Therapies and cardiac rehabilitation service identified 222 cardiac patients (142 males; 80 females) with comorbid anxiety and/or depression to access the pathway over 29 months. Patients accessed psychological therapy using the Improving Access to Psychological Therapies stepped-care model, where therapy intensity and durations varied according to patient need and complexity. Psychological outcomes were measured at three time points: assessment; end of contact; and 3-month follow up. Secondary care service usage was measured for 6 months before and after therapy. Results Significant improvements on all psychological outcomes were found when comparing scores between the three time points. Patients with coronary heart disease and myocardial infarction who received Improving Access to Psychological Therapies treatments had decreased use of secondary care hospital services. Conclusions An integrated Improving Access to Psychological Therapies and cardiac rehabilitation service can provide effective, adapted evidence-based psychological treatments for cardiac patients with comorbid anxiety and depression.

The papers for this issue explore the impact of open registries on inbreeding, in the working Australian Kelpie population particularly, and the impact of vehicle trauma on the canine shock index, as well as the potential role for lung ultrasound in monitoring for cardiogenic pulmonary oedema in dogs being treated for left-sided congestive heart failure.
Unsteady state diffusion-adsorption-reaction. Selectivity of consecutive reactions on porous catalyst particles
Authors: García Juan Rafael , Bidabehere Claudia María , Sedran Ulises 
Published: March 2021

Abstract
The simultaneous processes of diffusion, adsorption and chemical reaction, considering the transient nature of the concentration profiles in the porous catalyst particles as applied to the analysis of consecutive reactions A → B → C, where reactant and products are subjected to diffusion limitations, are analyzed. The concentrations of the desired intermediate product B, both the average in the catalytic particles and the observed in the fluid phase, initially increase as a function of time until reaching a maximum value and then decline due to the consumption in the secondary reaction. Due to the diffusion restrictions and the adsorption effect, the observed selectivities, calculated from the concentrations in the fluid phase, are always lower than the true selectivities, which also include the amounts accumulated in the particles. Besides depending on the rates of the primary and secondary reactions, the observed yield of product B also depends on the system adsorption capacity, i.e., the relationship between the capacities of the particles and the external fluid phase to accumulate the reactant species. For a given relationship between the intrinsic rates of the primary and secondary reactions, the higher the system adsorption capacity, the lower the observed yield of B as a function of conversion. The relationship between the observed yield of B and the observed conversion of A, calculated considering the transient state of the concentration profiles in the particles, is coincident with that predicted by classical models, which assume the steady state in the particles, when the system adsorption capacity is extremely small.

Published: March 2021

Abstract
Cyclic voltammetry, 1H nuclear magnetic resonance and quantum chemistry calculations were applied to explore the hydrogen bond interactions between ascorbic acid (AA) and glycine. The experimental results demonstrate the existence of hydrogen bonds in AA-glycine system, which has a significant effect on the oxidation peak potentials and currents of AA and the chemical shifts of glycine. The formation of hydrogen bonds between AA and glycine were further confirmed by the density functional theory, quantum theory of atoms in molecules and natural bond orbital analyses.

Published: March 2021

Objective: To explore the effects of music video therapy on pain among preschool children after cardiothoracic surgery.
Methods: Patients in the music video therapy (MVT) group received a 30-min music video intervention, while patients in the music therapy (MT) group received a 30-min musical intervention. Both groups were given their respective therapy three times a day for three days. Patients in the control group did not receive MVT or MV. Measures, including pain scores, vital signs (heart rate, mean arterial pressure, respiratory rate, and oxygen saturation), and other postoperative indicators were recorded and analyzed.
Results: The MVT group showed a statistically significant decrease in heart rate, mean arterial pressure, and respiratory rate at the first day after surgery and pain scores at the first and second day after surgery compared to the MT group, but no significant difference was identified in oxygen saturation. The postoperative indicators including cumulative capacity of sufentanil use, the length of intensive care unit (ICU) stay, and the length of hospital stay in the MVT group were significantly lower than those in the control group.
Conclusion: The findings provide further evidence to support the practice of music video therapy as a non-pharmaceutical intervention to reduce postoperative pain, reduce the dosage of analgesics, shorten the length of ICU and hospital stay in preschool children after the cardiothoracic surgery.

Published: March 2021

Versatile Peroxidases are high redox potential peroxidases capable of degrading lignin of lignocellulosic crop residues. Hence Versatile Peroxidases are prominent biocatalysts in upgrading lignocellulosic biomass for biotechnological applications. In the interest of exploiting the potential of Versatile Peroxidase in improving the digestibility of crop residues through delignification, a novel Versatile Peroxidase was purified and characterized from the immobilized cultures of native isolate Lentinus squarrosulus. The enzyme was purified with a specific activity of 62 U/mg through ion exchange and gel filtration chromatographic procedures. The enzyme possessed high affinity towards RB5 and manganese with a Km value of 6.84 µM for RB5 and 0.15 mM for manganese. The optimum temperature for oxidation was identified to be 30°C and optimum pH for manganese and RB5 oxidation was 5 and 3 respectively. Reactivity of the enzyme towards diverse substrates was investigated besides studying the effect of metal ions and inhibitors on RB5 oxidation. The enhanced potential of this purified Versatile Peroxidase in biodegradation of crop residues was demonstrated through augmentation of digestibility of finger millet and paddy straws by 20%.The results demonstrated that Versatile Peroxidase from Lentinus squarrosulus is capable of enhancing the nutritive value of crop residues through delignification
Effects of seed rates and row spacing on yield and yield components of linseed (Linum usitatissimum L) at Dabat district of North Gondar Zone, Ethiopia
Authors: Tadesse Daniel , Ousman Yenus , Teshome Mequanint 
Published: March 2021

The area coverage and productivity of linseed decreased from time to time; even there is no crop package and recommended row spacing and seed rate at regional level due to lack of attention by researchers and also by farmers. In Ethiopia, linseed has been cultivated for two primary purposes, seed and oil use. Its production in Ethiopia country is characterized by low input, low yield and poor product quality mainly due to attitude and poor management practices such as lack of proper weed management system, poor seed and field hygiene, poor seed bed preparation, inadequate plant nutrition, inappropriate seeding rate and spacing (mostly broad casting), improper threshing ground and improper cleaning. Field experiment was carried out to evaluate the effects of seed rate and row spacing on the yield and yield components of linseed, during 2017/2018 cropping season at Dabat district, North Western Ethiopia. KULUMSA1 (CHILALO) was used as test crop. Factorial combinations of three row spacing, (20, 25, and 30 cm) and three seed rates, (40, 45 and 50kgs) were laid out in RCBD with three replications. Data regarding different parameters were recorded from days to sowing up to different stages. Statistical analysis of data showed that most of the parameters were affected by the main effects of Seed Rates and Row spacing. The main effect of seed rate was highly significant for days maturity, thousand seed weight and harvest index of linseed. More over it was significant for days to flower and number of capsule per plant, but it was not significant to plant height and bio mass yield. The main effect of row spacing was significant for days to maturity. The interaction of seed rate and row spacing was highly significance (p<0.05) for number of primarily branch per plant and seed yield. It was not significant on number of seeds per capsule, number of capsule per plant and thousand seed weight. The main finding of this research is highest seed yield (1771 kg ha-1 ) was obtained at 40kg ha-1 x 25 cm of row spacing while the lowest seed yield (752kg ha-1) was recorded at 50 kg ha-1 x 30 cm. 40kg ha-1 and 25cm is recommended to increase yield of linseed and its components. In conclusion the effect of seed rate and row spacing affects the important yield components of linseed.
Antibacterial properties of capsaicin and its derivatives and their potential to fight antibiotic resistance – A literature survey
Authors: Füchtbauer Samuel , Mousavi Soraya , Bereswill Stefan , Heimesaat Markus M. 
Published: March 2021

AbstractAntibiotic resistance is endangering public health globally and gives reason for constant fear of virtually intractable bacterial infections. Given a limitation of novel antibiotic classes brought to market in perspective, it is indispensable to explore novel, antibiotics-independent ways to fight bacterial infections. In consequence, the antibacterial properties of natural compounds have gained increasing attention in pharmacological sciences. We here performed a literature survey regarding the antibacterial effects of capsaicin and its derivatives constituting natural compounds of chili peppers. The studies included revealed that the compounds under investigation exerted i.) both direct and indirect antibacterial properties in vitro depending on the applied concentrations and the bacterial strains under investigation; ii.) synergistic antibacterial effects in combination with defined antibiotics; iii.) resistance-modification via inhibition of bacterial efflux pumps; iv.) attenuation of bacterial virulence factor expression; and v.) dampening of pathogen-induced immunopathological responses. In conclusion, capsaicin and its derivatives comprise promising antimicrobial molecules which could complement or replace antibiotic treatment strategies to fight bacterial infections. However, a solid basis for subsequent clinical trials requires future investigations to explore the underlying molecular mechanisms and in particular pharmaceutical evaluations in animal infection models.
SADA communique to members - Licence and quality control tests for dental diagnostic X-ray imaging systems
Authors: SADA Head Office  
Published: March 2021

Members have been receiving notification from Inspection Bodies about their X-ray equipment being due for inspection.
On enquiry, it has been discovered that, in some instances, this notice was based on erroneous data that Inspection bodies may have received from the Radiation Control, who had not correctly updated their records, due to "a lack of manpower".
SADA strongly advises members who receive this notification to check their documentation before booking said inspections and, if the notification is incorrect, to request their usual inspection body to correct their records.
SADA has serious concerns about the current legal framework and enforcement of the Act governing X-ray equipment. It questions the Code of Practice and more particularly, the legal standing of inspection bodies, licensing delays and the entire legislative framework. To this end, SADA has made an extensive written submission to the Minister of Health raising our concerns. In the meantime, as the legislative framework applies to practitioner, in its flawed framework, we provide members useful information for the benefit of members around the whole issue of licensing and testing of X-ray equipment so that members are properly informed when receiving notices of inspections or having to licence their new or used X-ray equipment.
