Broussonetia papyrifera Root Bark Extract Exhibits Anti-inflammatory Effects on Adipose Tissue and Improves Insulin Sensitivity Potentially Via AMPK Activation

The chronic low-grade inflammation in adipose tissue plays a causal role in obesity-induced insulin resistance and its associated pathophysiological consequences. In this study, we investigated the effects of extracts of Broussonetia papyrifera root bark (PRE) and its bioactive components on inflammation and insulin sensitivity. PRE inhibited TNF-α-induced NF-κB transcriptional activity in the NF-κB luciferase assay and pro-inflammatory genes’ expression by blocking phosphorylation of IκB and NF-κB in 3T3-L1 adipocytes, which were mediated by activating AMPK. Ten-week-high fat diet (HFD)-fed C57BL6 male mice treated with PRE had improved glucose intolerance and decreased inflammation in adipose tissue, as indicated by reductions in NF-κB phosphorylation and pro-inflammatory genes’ expression. Furthermore, PRE activated AMP-activated protein kinase (AMPK) and reduced lipogenic genes’ expression in both adipose tissue and liver. Finally, we identified broussoflavonol B (BF) and kazinol J (KJ) as bioactive constituents to suppress pro-inflammatory responses via activating AMPK in 3T3-L1 adipocytes. Taken together, these results indicate the therapeutic potential of PRE, especially BF or KJ, in metabolic diseases such as obesity and type 2 diabetes.
Reflections on Doctor Question – Patient Answer Sequences and on Lay Perceptions of Close Translation

ABSTRACT The lay perception of those who work with interpreters in their professional conversations (and sometimes of interpreters themselves) is that translation of what they and their patients/clients say should be as close as possible. The very idea of close translation may seem simple, but the practice of rendering spontaneous talk-in-interaction as close as possible is quite complex, and requires much more from the mediator than textually close renditions. In this paper, we discuss what is involved in the accomplishment of close rendering in talk. We focus on question-answer sequences with clinicians and patients, when details about the patients’ history and their symptoms are collected. We show that meaning is achieved and rendered through processes that may go rather beyond the single words and utterances and that involve the contribution of all the interlocutors. We show three types of sequences taken from a collection of authentic data audio-recorded in health care services in Italy and transcribed to allow for analysis. The sequences show three different forms of talk, found in the data, where participants pursue close, precise rendition of medical details. The analysis highlights that the Italian intercultural mediators (just like those trained and assigned as public service interpreters in other countries), even in these cases which are peculiarly focused on precise details, do need to take responsibility not only for translating the textual items but also for coordinating turns at talk. It is responsible turn-coordination which leads to rendering meaning closely.
Effects of Virtual Reality-Based Rehabilitation on Burned Hands: A Prospective, Randomized, Single-Blind Study

Hands are the most frequent burn injury sites. Appropriate rehabilitation is essential to ensure good functional recovery. Virtual reality (VR)-based rehabilitation has proven to be beneficial for the functional recovery of the upper extremities. We investigated and compared VR-based rehabilitation with conventional rehabilitation (CON) in patients with burned hands. Fifty-seven patients were randomized into a VR or CON group. Each intervention was applied to the affected hand for four weeks, and clinical and functional variables were evaluated. Hand function was evaluated before intervention and four weeks after intervention using the Jebsen-Taylor hand function test (JTT), Grasp and Pinch Power Test, Purdue Pegboard test (PPT), and Michigan Hand Outcomes Questionnaire (MHQ). The JTT scores for picking up small objects and the MHQ scores for hand function, functional ADL, work, pain, aesthetics, and patient satisfaction were significantly higher in the VR group than in the CON group (p < 0.05). The results suggested that VR-based rehabilitation is likely to be as effective as conventional rehabilitation for recovering function in a burned hand. VR-based rehabilitation may be considered as a treatment option for patients with burned hands.
Halogenation‐Guided Chemical Screening Provides Insight into Tjipanazole Biosynthesis by the Cyanobacterium Fischerella ambigua

Halogenated natural products (HNPs) show a wide range of interesting biological activities. Chemistry‐guided screening with a software tool dedicated to identifying halogenated compounds in HPLC‐MS data indicated the presence of several uncharacterised HNPs in an extract of the cyanobacterium Fischerella ambigua (Näg.) Gomont 108b. Three new natural products, tjipanazoles K, L, and M, were isolated from this strain together with the known tjipanazoles D and I. Taking into account the structures of all tjipanazole derivatives detected in this strain, reanalysis of the tjipanazole biosynthetic gene cluster allowed us to propose a biosynthetic pathway for the tjipanazoles. As the isolated tjipanazoles show structural similarity to arcyriaflavin A, an inhibitor of the clinically relevant multidrug‐transporter ABCG2 overexpressed by different cancer cell lines, the isolated compounds were tested for ABCG2 inhibitory activity. Only tjipanazole K showed appreciable transporter inhibition, whereas the compounds lacking the pyrrolo[3,4‐c] ring or featuring additional chloro substituents were found to be much less active.
Preoperative renal malperfusion is an independent predictor for acute kidney injury and operative death but not associated with late mortality after surgery for acute type A aortic dissection.

OBJECTIVES This study was aimed to investigate the impact of preoperative renal malperfusion on early and late outcomes after surgery for acute type A aortic dissection (AAAD). METHODS Of 915 patients who underwent surgery for AAAD between September 2004 and September 2017, we enrolled 534 patients whose preoperative enhanced computed tomography images were retrospectively available in this study. Exclusion criteria were single kidney (n = 3) and dialysis-dependent preoperatively (n = 12). We compared early and late outcomes between patients who had preoperative renal malperfusion (n = 64) and those who did not have renal malperfusion (n = 470). RESULTS The incidence of postoperative acute kidney injury, defined using the Kidney Disease: Improving Global Outcomes criteria, was higher in the renal malperfusion group than in the no renal malperfusion group (76.6% vs 39.4%; P < 0.001). Similarly, operative death was more frequently seen in the renal malperfusion group (12.5% vs 3.8%; P = 0.003). Multivariate analyses showed that renal malperfusion was the independent predictor for postoperative acute kidney injury [odds ratio 4.32, 95% confidence interval (CI) 2.25-8.67; P < 0.001] and operative death (odds ratio 3.08, 95% CI 1.02-8.86; P = 0.046). The median follow-up period in the hospital survivors was 3.3 years (interquartile range 2.1-6.7 years). The cumulative survival rate at 8 years was similar between the groups (74.6% in the renal malperfusion group and 76.0% in the no renal malperfusion group; P = 0.349). CONCLUSIONS Preoperative renal malperfusion is an independent predictor for postoperative acute kidney injury and operative death but not associated with late mortality after surgery for acute type A aortic dissection.
Advanced Ankle and Foot Sonoanatomy: Imaging Beyond the Basics

Ankle/foot pain is a common complaint encountered in clinical practice. Currently, due to the complex anatomy, the diagnosis and management of the underlying musculoskeletal disorders are extremely challenging. Nowadays, high-resolution ultrasound has emerged as the first-line tool to evaluate musculoskeletal disorders. There have been several existing protocols describing the fundamental sonoanatomy of ankle/foot joints. However, there are certain anatomic structures (e.g., Lisfranc ligament complex or Baxter nerve) which are also clinically important. As they are rarely elaborated in the available literature, a comprehensive review is necessary. In this regard, the present article aims to brief the regional anatomy, illustrate the scanning techniques, and emphasize the clinical relevance of the ankle/foot region.
The Oxygen Consumption Kinetics of Commercial Oenological Tannins in Model Wine Solution and Chianti Red Wine

One property of oenological tannins, oxygen reactivity, is commonly exploited in winemaking. The reactivity is mediated by the presence of catalysts (i.e., transition metals and sulfur dioxide) and protects wine against oxidation. This work compares the oxygen consumption rate (OCR) of four commercial oenological tannins (two procyanidins from grape skin and seed, an ellagitannin from oak wood and a gallotannin from gallnut) in a model wine solution and Chianti red wine. All samples were subjected to consecutive cycles of air saturation at 20 °C to increase the total level of oxygen provided. After each cycle, the oxygen level was measured by means of a non-invasive luminescent sensor glued to a transparent surface (sensor dots) until there was no further change in substrate reactivity. The OCR followed first-order kinetics, regardless of the tannin. As expected, the ellagitannin showed the fastest OCR, followed by the two from grape seeds and skins and finally the gallotannin. The total O2 consumption in the red wine was almost double that of the model solution, due to the oxidation of wine substrates. The measurement of OCR is helpful for setting up an advanced winemaking protocol that makes use of tannins to reduce the use of sulfur dioxide.
Discovery of non‐HLA antibodies associated with cardiac allograft rejection and development and validation of a non‐HLA antigen multiplex panel: From bench to bedside

We analyzed humoral immune responses to nonhuman leukocyte antigen (HLA) after cardiac transplantation to identify antibodies associated with allograft rejection. Protein microarray identified 366 non‐HLA antibodies (>1.5 fold, P < .5) from a discovery cohort of HLA antibody–negative, endothelial cell crossmatch–positive sera obtained from 12 cardiac allograft recipients at the time of biopsy‐proven rejection. From these, 19 plasma membrane proteins and 10 autoantigens identified from gene ontology analysis were combined with 48 proteins identified through literature search to generate a multiplex bead array. Longitudinal sera from a multicenter cohort of adult cardiac allograft recipients (samples: n = 477 no rejection; n = 69 rejection) identified 18 non‐HLA antibodies associated with rejection (P < .1) including 4 newly identified non‐HLA antigenic targets (DEXI, EMCN, LPHN1, and SSB). CART analysis showed 5/18 non‐HLA antibodies distinguished rejection vs nonrejection. Antibodies to 4/18 non‐HLA antigens synergize with HLA donor‐specific antibodies and significantly increase the odds of rejection (P < .1). The non‐HLA panel was validated using an independent adult cardiac transplant cohort (n = 21 no rejection; n = 42 rejection, >1R) with an area under the curve of 0.87 (P < .05) with 92.86% sensitivity and 66.67% specificity. We conclude that multiplex bead array assessment of non‐HLA antibodies identifies cardiac transplant recipients at risk of rejection.
Using Multiple Mini-Interviews for Students’ Admissions in Pakistan: A Pilot Study

Background A significant challenge continuing to face medical educators is the development of an effective method for student admissions into medical school. Conventional interviews have been commonly used for assessment of non-cognitive skills; however, they are subject to different biases and lack of standardization. The present study aims to determine the validity, reliability, feasibility, and acceptability of implementing Multiple Mini-Interviews (MMI) as a selection method for undergraduate medical students. Methods MMI consisting of 8 stations was developed and implemented. A variance component analysis was computed to identify different sources of variance and estimate overall reliability. Content validity was established by seeking consensus on non-cognitive attributes desired by stakeholders. Acceptability and feasibility were determined by a post-MMI questionnaire. Results A total of 381 out of 450 (84.66%) candidates participated in the study. The G coefficient was 0.70. Participants found MMI as an acceptable and feasible method of assessment, with 75% of candidates and 95% of assessors preferring MMI to traditional interviews. Conclusion MMI as an assessment method for students’ admissions demonstrated reliable findings. Stakeholders found it feasible and acceptable. Individual institutions can tailor the stations towards selection of the characteristics that are most valued within their local context.
Isolation and Quantification of Uremic Toxin Precursor-Generating Gut Bacteria in Chronic Kidney Disease Patients

In chronic kidney disease (CKD), impaired kidney function results in accumulation of uremic toxins, which exert deleterious biological effects and contribute to inflammation and cardiovascular morbidity and mortality. Protein-bound uremic toxins (PBUTs), such as p-cresyl sulfate, indoxyl sulfate and indole-3-acetic acid, originate from phenolic and indolic compounds, which are end products of gut bacterial metabolization of aromatic amino acids (AAA). This study investigates gut microbial composition at different CKD stages by isolating, identifying and quantifying PBUT precursor-generating bacteria. Fecal DNA extracts from 14 controls and 138 CKD patients were used to quantify total bacterial number and 11 bacterial taxa with qPCR. Moreover, isolated bacteria from CKD 1 and CKD 5 fecal samples were cultured in broth medium supplemented with AAA under aerobic and anaerobic conditions, and classified as PBUT precursor-generators based on their generation capacity of phenolic and indolic compounds, measured with U(H)PLC. In total, 148 different fecal bacterial species were isolated, of which 92 were PBUT precursor-generators. These bacterial species can be a potential target for reducing PBUT plasma levels in CKD. qPCR indicated lower abundance of short chain fatty acid-generating bacteria, Bifidobacterium spp. and Streptococcus spp. , and higher Enterobacteriaceae and E. coli with impaired kidney function, confirming an altered gut microbial composition in CKD.
Evaluation of the Visual Stimuli on Personal Thermal Comfort Perception in Real and Virtual Environments Using Machine Learning Approaches

Personal Thermal Comfort models consider personal user feedback as a target value. The growing development of integrated “smart” devices following the concept of the Internet of Things and data-processing algorithms based on Machine Learning techniques allows developing promising frameworks to reach the best level of indoor thermal comfort closest to the real needs of users. The article investigates the potential of a new approach aiming at evaluating the effect of visual stimuli on personal thermal comfort perception through a comparison of 25 participants’ feedback exposed to a real scenario in a test cell and the same environment reproduced in Virtual Reality. The users’ biometric data and feedback about their thermal perception along with environmental parameters are collected in a dataset and managed with different Machine Learning techniques. The most suitable algorithm, among those selected, and the influential variables to predict the Personal Thermal Comfort Perception are identified. The Extra Trees classifier emerged as the most useful algorithm in this specific case. In real and virtual scenarios, the most important variables that allow predicting the target value are identified with an average accuracy higher than 0.99.
Effects of Inclusion of Fresh Forage in the Diet for Lactating Buffaloes on Volatile Organic Compounds of Milk and Mozzarella Cheese

This paper aimed to assess the effects of feeding fresh forage on volatile organic compounds (VOCs) of buffalo milk and mozzarella cheese. Sixteen lactating buffaloes were equally allotted into two groups fed diets containing (experimental (Exp) group) or not (control (Ctl) group) 20 kg/d of fresh sorghum. Milk from the groups was separately collected and transformed in the traditional ‘Mozzarella di Bufala Campana’ Protected Denomination of Origin (PDO). Three batches of mozzarella were produced for each diet and they were analyzed, along with the two bulks of milk, for VOC composition, by using solid phase micro-extraction (SPME) coupled with gas-chromatography/mass spectrometry (GC/MS). The use of fresh forage increased the levels of long chain fatty acids along with the contents of aldehydes, and this could be responsible for an increase in green notes of milk. The use of the Ctl diet, containing a higher proportion of silage, increased the ketones, acids, and esters, which are compounds that could raise the cheese and fruity notes of milk. The mozzarella was less affected by the dietary treatment than milk. The use of fresh forage (sorghum) enhanced the green notes of milk and induced a few changes in the VOC profile of the typical PDO Mozzarella di Bufala Campana cheese, that were nonetheless detectable by sensory analysis. The low level found for butanoic acid, 2,3-pentanedione, and propyl acetate in mozzarella cheese obtained with fresh forage diet can lead to perceive less the olfactory notes of cheese, cream, and fruit.
A Novel Adaptive Recursive Least Squares Filter to Remove the Motion Artifact in Seismocardiography

This paper presents a novel adaptive recursive least squares filter (ARLSF) for motion artifact removal in the field of seismocardiography (SCG). This algorithm was tested with a consumer-grade accelerometer. This accelerometer was placed on the chest wall of 16 subjects whose ages ranged from 24 to 35 years. We recorded the SCG signal and the standard electrocardiogram (ECG) lead I signal by placing one electrode on the right arm (RA) and another on the left arm (LA) of the subjects. These subjects were asked to perform standing and walking movements on a treadmill. ARLSF was developed in MATLAB to process the collected SCG and ECG signals simultaneously. The SCG peaks and heart rate signals were extracted from the output of ARLSF. The results indicate a heartbeat detection accuracy of up to 98%. The heart rates estimated from SCG and ECG are similar under both standing and walking conditions. This observation shows that the proposed ARLSF could be an effective method to remove motion artifact from recorded SCG signals.
Histopathological and Morphometric Evaluation in the Testis and Epididymis of Adult Rats Submitted To A Recovery Period after Treatment with Anabolic Steroid, Alcohol and/or Nicotine

AAS are recommended for treatment of sarcopenia and cachexia associated with AIDS, hepatic or renal failure, cancer and severe burns [4,5], but their nonmedical use is increasing during the latest decades. These substances are synthetic derivatives of testosterone that act on androgenic receptors, which are present in several different types of tissues, conferring inseparable anabolic and androgenic effects [6]. Because of its anabolic effect in promoting increased muscle mass, many people use AAS for esthetic reasons [7,8] and this nonclinic use may cause reversible and irreversible side effects [9]. In men and rodents, testicular changes and reduction in the quality of semen are widely reported in the literature as result of AAS use [10-13].
Suppression of a Subset of Interferon-Induced Genes by Human Papillomavirus Type 16 E7 via a Cyclin Dependent Kinase 8-Dependent Mechanism

Persistent infection by human papillomaviruses (HPVs), small, double-stranded DNA viruses that infect keratinocytes of the squamous epithelia, can lead to the development of cervical and other cancers. The viral oncoprotein E7 contributes to viral persistence in part by regulating host gene expression through binding host transcriptional regulators, although mechanisms responsible for E7-mediated transcriptional regulation are incompletely understood. Type I IFN signaling promotes the expression of anti-viral genes, called interferon-stimulated genes (ISGs), through the phosphorylation and activation of STAT1. In this study, we have observed that the CR3 domain of E7 contributes to the episomal maintenance of viral genomes. Transcriptome analysis revealed that E7 transcriptionally suppresses a subset of ISGs but not through regulation of STAT1 activation. Instead, we discovered that E7 associates with Mediator kinase CDK8 and this is correlated with the recruitment of CDK8 to ISG promoters and reduced ISG expression. E7 fails to suppress ISGs in the absence of CDK8, indicating that CDK8 function contributes to the suppression of ISGs by E7. Altogether, E7/CDK8 association may be a novel mechanism by which E7 inhibits innate immune signaling.
Hospice social workers’ perception of being valued by the interdisciplinary team and the association with job satisfaction

ABSTRACT Being valued and respected by colleagues is an important contributor to job satisfaction in hospice and other health care settings. The purpose of this study was to examine how the perception of feeling valued by different members of the interdisciplinary team and interdependence of team members are related to hospice social workers’ job satisfaction. The study aims were to examine: (1) the degree to which hospice social workers feel valued by other members of the interdisciplinary team; and 2) whether this is associated with job satisfaction. A nonprobability sample of 203 hospice social workers completed an online survey assessing job satisfaction, perception of feeling valued by each of the professionals on the interdisciplinary hospice team, interdependence of team members, and professional and personal characteristics. The final regression model for intrinsic job satisfaction included feeling valued by doctors and by other social workers, and interdisciplinary interdependence. The final model for extrinsic job satisfaction did not include any of the perception of feeling valued by others on the interdisciplinary team, although interdependence and the number of social workers at the hospice were significant in this model. Reasons for the difference in these models and the practice and policy implications are discussed.
