Abstract
Background
Lung cancer remains the leading cause of cancer mortality worldwide. Early detection of lung cancer helps improve treatment and survival. Numerous aberrant DNA methylations have been reported in early-stage lung cancer. Here, we sought to identify novel DNA methylation biomarkers that could potentially be used for noninvasive early diagnosis of lung cancers.

Methods
This prospective-specimen collection and retrospective-blinded-evaluation trial enrolled a total of 317 participants (198 tissues and 119 plasmas) comprising healthy controls, patients with lung cancer and benign disease between January 2020 and December 2021. Tissue and plasma samples were subjected to targeted bisulfite sequencing with a lung cancer specific panel targeting 9,307 differential methylation regions (DMRs). DMRs associated with lung cancer were identified by comparing the methylation profiles of tissue samples from patients with lung cancer and benign disease. Markers were selected with minimum redundancy and maximum relevance algorithm. A prediction model for lung cancer diagnosis was built through logistic regression algorithm and validated independently in tissue samples. Furthermore, the performance of this developed model was evaluated in a set of plasma cell-free DNA (cfDNA) samples.

Results
We identified 7 DMRs corresponding to 7 differentially methylated genes (DMGs) including HOXB4, HOXA7, HOXD8, ITGA4, ZNF808, PTGER4, and B3GNTL1 that were highly associated with lung cancer by comparing the methylation profiles of lung cancer and benign nodule tissue. Based on the 7-DMR biomarker panel, we developed a new diagnostic model in tissue samples, termed “7-DMR model”, to distinguish lung cancers from benign diseases, achieving AUCs of 0.97 (95%CI: 0.93-1.00)/0.96 (0.92-1.00), sensitivities of 0.89 (0.82–0.95)/0.92 (0.86–0.98), specificities of 0.94 (0.89–0.99)/1.00 (1.00–1.00), and accuracies of 0.90 (0.84–0.96)/0.94 (0.89–0.99) in the discovery cohort (n = 96) and the independent validation cohort (n = 81), respectively. Furthermore, the 7-DMR model was applied to noninvasive discrimination of lung cancers and non-lung cancers including benign lung diseases and healthy controls in an independent validation cohort of plasma samples (n = 106), yielding an AUC of 0.94 (0.86-1.00), sensitivity of 0.81 (0.73–0.88), specificity of 0.98 (0.95-1.00), and accuracy of 0.93 (0.89–0.98).

Conclusion
The 7 novel DMRs could be promising methylation biomarkers that merits further development as a noninvasive test for early detection of lung cancer.

Abstract
Grisaille was the first paint applied on stained-glass panels, used in Europe since the twelfth century. Historical written sources described the use of iron and copper together with a high lead-silica base glass in the grisailles production. This project aims to study the evolution of the grisaille paint composition throughout time and the changes in the raw materials used in their production using non-destructive and non-invasive techniques. To achieve this objective, 23 grisaille samples dated from the 13th to the twentieth centuries from nine different countries (Portugal, Poland, United Kingdom, Sweden, Norway, Belgium, Low Countries, Germany, and France) were studied by means of micro particle-induced X-ray emission (μ-PIXE), micro energy dispersive X-ray fluorescence (μ-EDXRF), laser-induced breakdown spectroscopy (LIBS), laser-induced fluorescence (LIF), non-linear optical microscopy (NLOM) in the modality of multiphoton excitation fluorescence (MPEF) and optical microscopy (OM). The results showed that it was possible to identify compositional differences and patterns throughout the samples when compared with literature results. The preference for using copper in central and south-central European countries and the addition of new compounds (CoO, Cr2O3, MnO) as colouring agents since the nineteenth century was verified. The LIBS analyses allow the identification of boron on two samples, confirming the change of base glass components since the seventeenth century. The NLOM-MPEF showed the capability of this technique to measure the grisaille paint layers’ thickness. This non-invasive multi-analytical and complementary approach proves itself efficient in identifying changes in the grisaille’s composition throughout time, which can be interpreted as changes in the raw materials and manufacture used in the production of these paint materials.
Fake news detection on social media: the predictive role of university students’ critical thinking dispositions and new media literacy
Authors: Orhan Ali 
Published: April 2023

AbstractThis study aimed to investigate the predictive role of critical thinking dispositions and new media literacies on the ability to detect fake news on social media. The sample group of the study consisted of 157 university students. Sosu Critical Thinking Dispositions Scale, New Media Literacy Scale, and fake news detection task were employed to gather the data. It was found that university students possess high critical thinking dispositions and new media literacies as well as high fake news detection abilities and there is a positive and moderate relationship among these variables. Also, this study revealed that critical thinking dispositions and new media literacies significantly predicted university students’ abilities to detect fake news on social media and they together explained 18% of the total variance on fake news detection. Besides, university students’ critical thinking dispositions presented a larger effect on their abilities to detect fake news than new media literacies.

AbstractPurposeTo discuss recent literature on posterior cruciate ligament (PCL) repair and report on the clinical and radiological outcomes.MethodsA systematic review was conducted according to the PRISMA guidelines. In August 2022, three databases (PubMed, Scopus, and Cochrane Library) were searched for studies on PCL repair by two independent reviewers. Articles published between January 2000 and August 2022 focussing on the clinical and/or radiological outcomes, following PCL repair, were included. Patient demographic data, clinical evaluations, patient‑reported outcome measures, post‐operative complications and radiological outcomes were extracted.ResultsNine studies met the inclusion criteria, covering 226 patients with a mean age ranging from 22.4 to 38.8 years and mean follow‐up periods ranging from 14 to 78.6 months. Seven studies (77.8%) were level IV and two studies (22.2%) were level III. Arthroscopic PCL repair was performed in four studies (44.4%) while the remaining five studies (55.6%) described open PCL repair. In four studies (44.4%) additional suture augmentation was applied. Arthrofibrosis affected a combined total of 24 patients (11.7%; range 0–21.0%) making it the most common complication and the overall failure rate was 5.6%, ranging from 0 to 15.8%. Two studies (22.2%) performed post‐operative MRI and confirmed PCL healing.ConclusionThis systematic review indicates that PCL repair can be a safe procedure with an overall failure rate of 5.6%, ranging from 0% to 15.8%. However, more high quality research is necessary before widespread clinical implementation is warranted.Level of EvidenceIV.

Abstract
Background
Laparoscopic splenectomy for patients with portal hypertension is associated with a high risk of bleeding. The use of vessel-sealing devices and automatic sutures is important for bleeding control. However, a rare complication of abdominal surgery is the direct communication between the arterial and portal circulation related to surgical procedures such as simultaneous ligature of an artery and adjacent vein. We describe a rare case of omental arteriovenous fistula (AVF) after laparoscopic splenectomy treated with transarterial embolization.

Case presentation
We report a case of a 46-year-old male patient with an omental AVF after a laparoscopic splenectomy 6 years ago for splenomegaly associated with alcoholic cirrhosis. Follow-up abdominal dynamic computed tomography accidentally revealed a vascular sac (25 mm in the major axis) that formed an omental AVF with anastomosis to the left colonic vein. The communication was considered to be caused by using a vessel-sealing device. No symptoms related to the AVF were observed. The AVF was embolized with microcoils using the transarterial approach. A 4-axis catheter system was used for accurate embolization due to the long and tortuous distance from the celiac artery. No recurrence or symptoms were observed after 6 months.

Conclusions
Treatment of arterioportal fistula is mandatory, even in asymptomatic patients. Embolization is a less invasive alternative to surgical approaches. The 4-axis catheter system was useful for accurate embolization via a long and tortuous artery.

Abstract
Background
The bitter gourd fruit yields are not at a desirable level due to maleness. Maleness is one of the biggest difficulties with bitter gourd, reducing fruit yields substantially. On the other hand, plant stages are the most important consideration for PGR application because of their sensitive responsiveness. Therefore, it is necessary to determine how bitter gourd plants respond to plant growth regulators, namely PGR0 (control: application of water as control treatment), PGR1 (GA3-Gibberellic acid, 100 mgL−1), PGR2 (NAA-Naphthalene acetic acid, 100 mgL−1), and PGR3 (MH- Maleic hydrazide, 100 mgL−1) at three application phases, S1: soaking of seeds; S2: four-leaf; and S3: flower bud in terms of vegetative development, male–female flower sex alteration, and fruit features including bioactive compounds.

Results
Physiological, floral and yield characteristics of bitter gourd exposed significant changes by GA3 and MH at various stages. The number of leaves plant−1, the fresh mass of the plant, and the fresh mass of fruit and fruit dry matter content were enhanced remarkably for MH application at the seed soaking stage except for plant height and the number of branches plant−1. MH increased the number of female flowers plant−1, the number of fruits plant−1 and the yield at the 4-leaf stage of application. PGRs substantially influenced the quantity of sugar, chlorophyll, total carotenoids, protein, and water content at various phases of their application but not on ascorbic acid, TSS, or total phenol concentration.

Conclusions
For sex expression and yield attributes, 100 mgL−1 MH at the 4-leaf stage would be effective in bitter gourd. Exogenous NAA showed a considerable dual influence on plant development and antioxidant enzyme activity in bitter gourd fruits.

Published: April 2023

Abstract
Background
Sleep disorders are common in postmenopausal women and are linked to poor physical and mental health, which affect quality of life. Therefore, this study aimed to investigate the effect of resistive exercise on insomnia and sleep quality in postmenopausal women. Fifty-six postmenopausal women suffering from sleep disturbance and insomnia participated in this study. Their age ranged from 50–65 years, and their body mass index (BMI) was 25–29.5 kg/m2. They were randomly distributed into two groups of an equal number. Control group received self-care and lifestyle advice, while study group received the same advice in addition to resistive exercises for 20–30 min per session for 4 weeks. Plasma estradiol levels were assessed, as well as the Pittsburgh Sleep Quality Index and Insomnia Severity Index, which were used to evaluate sleep quality and insomnia pre- and post-treatment.

Results
Control group revealed a significant decrease (p < 0.001) in Pittsburgh sleep quality index and insomnia severity index and a non-significant difference (p = 0.059) in plasma estradiol level post-treatment. However, study group showed a significant decrease (p < 0.001) in Pittsburgh sleep quality index and insomnia severity index, as well as a significant increase (p = 0.001) in plasma estradiol level. Compared to control group, study group showed a significant decrease (p = 0.000) in insomnia and sleep quality, as well as a non-significant difference (p = 0.179) in estradiol level post-treatment. Also, there was a negative correlation between plasma estradiol level and insomnia severity score in the study group post-treatment.

Conclusion
Resistive exercise is an effective modality for postmenopausal women suffering from sleep disorders as it improves insomnia, sleep quality, which in turn affects the quality of life. Increased estradiol level is an important factor that helps improve insomnia in postmenopausal women.

Published: April 2023

Abstract
Background
Infections in neonates are mainly caused by sepsis and are the most important complications of low birth weight. In the treatment of these infections, it is common to use broad-spectrum antibiotics such as cholestin. Cholestin can cause changes in the latency of brainstem-evoked response waves. The current cohort study tried to investigate the probability of changes caused by cholestin in LBW neonates and benefiting from two common tests to identify the hearing system in neonates after treatment by cholestin and compared them with a control group.

Methods
The study was an exposure-based cohort, during which hearing damage caused by receiving cholestin was evaluated in 104 low birth weight neonates, in two groups (52 exposure and 52 no-exposure to cholestin). OAE and ABR tests were performed at the age of 3 months to identify complications in two groups and their results were compared.

Results
The absolute latency of waves I, III, and V in the brainstem evoked response test with an intensity of 80 dB Hl showed a significant difference in the exposure group with the control group. The interpeak latency of the waves as well as the effect of the drug on the gender of the infants did not show significant differences with the control group.

Conclusion
Cholestin did not affect the axonal or synaptic transmission time of the auditory nerve to the brainstem. It is possible that the simultaneous presence of risk factors, such as the use of cholestin, low birth weight, noises in the intensive care unit, and other unknown factors, can be effective in the change of the absolute latency of waves.
Ultrasound-stimulated microbubbles enhanced vascular disruption in fractionated radiotherapy-treated tumours via ASMase activation
Authors: Leong Kai Xuan , Yang Wenyi , Sharma Deepa , Liu Stanley , Czarnota Gregory J. 
Published: April 2023

ABSTRACT
Recent studies have indicated that radiotherapy affects tumour vasculature as well as tumour cells. The use of ultrasound-stimulated microbubbles (USMB) can potentially enhance the effects of radiotherapy through the activation of the acid sphingomyelinase [ASMase or sphingomyelin phosphodiesterase 1 (SMPD1)]-ceramide pathway. ASMase knockout (ASMase−/−) and wild-type (WT) mice bearing fibrosarcoma (MCA/129 tumour line) were treated with 10 Gy or 20 Gy in five fractions alongside or independently of USMB treatments. The results indicated that tumour responses to fractionated radiotherapy (fXRT) were enhanced when fXRT was coupled with USMB as part of the treatment regimen. Sphingosine-1-phosphate (S1P)-treated mice and ASMase−/− mice demonstrated radioresistance against fXRT alone, whereas only ASMase−/− mice showed radioresistance against fXRT treatment alone and when combined with USMB. Results indicated that in WT and S1P-treated cohorts, the use of USMB with fXRT enhanced the tumour response compared to use of USMB or fXRT alone. Although in WT and S1P-treated cohorts, there was enhanced vascular disruption, ASMase−/− cohorts demonstrated no significant vascular disruption, indicating the importance of ASMase in facilitating vascular changes in response to fXRT and USMB treatment.
Ultrasound assessment of the inferior glenohumeral capsule in normal shoulders—a study of measurement variables and reliability
Authors: Shrestha-Taylor Sumi , Ginn Karen , Poulos Ann , Clarke Jillian L 
Published: April 2023

Objectives: To establish the reliability of a standardised ultrasound protocol to measure normal inferior glenohumeral capsule (IGHC) thickness and to investigate the effects of age, sex, hand dominance and angles of abduction on the thickness. Methods: IGHC images were obtained at 60o, 90o and 180o abduction angles of 151 asymptomatic shoulders in supine position. Following the proposed guidelines, three sonographers blindly measured the IGHC thicknesses for intra- and interrater reliability assessments. Results: The intrarater reliability was excellent (intraclass correlation coefficient value = 0.95; 95% CI = 0.92–0.97). The interrater reliability was moderate (intraclass correlation coefficient value = 0.74; 95% CI = 0.60–0.83). The mean IGHC thickness values in mm ± SD at 60o, 90o and 180o abduction angles for males were 3.3 ± 0.93, 3.0 ± 0.80 and 2.6 ± 0.55 and those for females were 2.7 ± 0.86, 2.4 ± 0.7 and 2.0 ± 0.56 respectively. Although males had thicker IGHC, the rate at which the thickness reduced with increased abduction was same in both males and females. Age and hand dominance had no effect. Conclusion: The normal IGHC thickness varies with sex and the abduction angle of the arm at which it is measured. A large variation of IGHC thickness exists in the normal population. Advances in knowledge: The results of this study discourage the use of a single value of IGHC thickness and emphasise the importance of comparing the thickness of the symptomatic side to that of the asymptomatic side of the same subject at the same abduction level. The guidelines provided in this study can be used in clinical practice and in future research studies.
Clinical applications of artificial intelligence in radiology

Published: April 2023

Abstract
The rapid growth of medical imaging has placed increasing demands on radiologists. In this scenario, artificial intelligence (AI) has become an attractive partner, one that may complement case interpretation and may aid in various non-interpretive aspects of the work in the radiological clinic. In this review, we discuss interpretative and non-interpretative uses of AI in the clinical practice, as well as report on the barriers to AI’s adoption in the clinic. We show that AI currently has a modest to moderate penetration in the clinical practice, with many radiologists still being unconvinced of its value and the return on its investment. Moreover, we discuss the radiologists’ liabilities regarding the AI decisions, and explain how we currently do not have regulation to guide the implementation of explainable AI or of self-learning algorithms.
Ex vivo comparative investigation of suprachiasmatic nucleus excitotoxic resiliency
Authors: Acharyya Debalina , Cooper Joanna , Prosser Rebecca A. 
Published: April 2023

Background: Glutamate signaling in the brain is regulated by release, reuptake, and receptor responsiveness. In diseased conditions, glutamate signaling can exceed normal regulatory processes, giving rise to a condition called excitotoxicity. Although regional differences in the excitotoxic effects of glutamate in the brain have been reported, the extent and characteristics of these potential differences are not clear. Here we compared the excitotoxic resiliency of the suprachiasmatic nucleus (SCN), anterior hypothalamus (AH) and cortex. Methods: We treated acute brain slices containing either the SCN and AH or the cortex from adult male mice at different times across the diurnal cycle with varying concentrations of N-methyl-D-aspartate (NMDA), NMDA+ α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) or control medium. The extent of cell damage was assessed using propidium iodide (PI), a cell death marker. Results: The results indicate that all three brain regions exhibited increasing cell damage/death when treated with increasing concentrations of NMDA. However, higher concentrations of NMDA were needed to significantly increase cell damage in the SCN compared to the cortex and AH. All three brain regions also exhibited greater cell death/damage when treated in the nighttime compared to the daytime, although the SCN exhibited increased cell death during a more restricted time interval compared to the AH and cortex. Conclusions: Together, these data confirm previous studies showing excitotoxic resiliency in the SCN, while extending them in two ways. First, we demonstrate a dose-dependency in excitotoxic susceptibility that differentiates the SCN from the surrounding AH and the cortex using a brain slice preparation. Second, we demonstrate a diurnal rhythm in excitotoxic susceptibility with a broadly similar phase across all three brain regions. These data increase our understanding of the extent and nature of the SCN excitotoxic resiliency, which will inform future studies on the cellular mechanisms underlying this phenomenon.
