Pedunculagin (PD), an ellagitannin found in different plant species, possesses several pharmaceutical properties, including antitumor, antioxidant, gastroprotective, hepatoprotective, and anti-inflammatory properties. However, the effects of PD alone on DNA remain to be determined. The aim of this study was to investigate the potential cytotoxic, genotoxic, and antigenotoxic activities of PD isolated from Plinia cauliflora seeds using in silico and in vitro assays. To elucidate the biological activities of PD, in silico tools indicative of antioxidant, antineoplastic, and chemopreventive activities of PD were used. Subsequently, the mutagenic/antimutagenic effects of PD were later assessed using bacteria with the Ames test, and the cytotoxic, genotoxic, and antigenotoxic effects utilizing human lymphocytes as evidenced by trypan blue exclusion test and CometChip assay. In silico analysis indicated potential antioxidant, chemopreventive, free radical scavenger, and cytostatic activities of PD. In the Ames test, PD was found to be not mutagenic; however, this plant component protected DNA against damage-mediated by mutagens 4-nitroquinoline-1-oxide and sodium azide. Regarding human lymphocytes, PD alone was cytotoxic and genotoxic; however, it also reduced DNA damage induced by doxorubicin at co- and post-treatment. In conclusion, PD showed genotoxic, antigenotoxic and cytotoxic effects in human lymphocytes and antimutagenic effects in bacteria.Monobenzyl ether of hydroquinone (MBEH) is a topical depigmentation agent used by vitiligo patients to even the skin tone. We aimed to investigate the effects of MBEH on 3T3 mouse fibroblasts. Fibroblasts were treated with 250 µM, 500 µM, and 750 µM MBEH and vehicle (EtOHDMSO) for 24 hours. Cell numbers of 250 µM, 500 µM, and 750 µM MBEH treated and vehicle groups decreased significantly compared to control group. TUNEL positive cell rate increased with MBEH concentration. In electron microscopic examination, control and vehicle groups showed active cells features, while mitochondrial swelling and cristae loss were seen in 250 µM MBEH-treated group. In cytoplasm of 500 µM MBEH-treated group, there were many multivesicular bodies and autophagic vacuoles. As an indication of apoptosis, cell membrane blebs and reduction in cell size were observed. In 750 μM MBEH-treated group, cells were completely degenerated. Our findings show that MBEH, which is used as a depigmentation agent to lighten the skin by destroying melanocytes, may also have dose-dependent negative effects on the viability of 3T3 mouse fibroblasts, and these may be mediated through autophagic and apoptotic cell death mechanisms.Objectives. Investigating the root causes of under-reporting near misses is very important. The aim of this study was investigating barriers to near-miss reporting in East Azerbaijan Province Gas Company from the perspective of health, safety and environment (HSE) officers. Methods. Semi-structured individual interviews were used and 21 interviews were conducted with HSE officers. Inductive content analysis was used for analyzing interviews. After analyzing the interviews, the codes in the interviews were categorized. Results. In general, two categories of code were created reasons for non-reporting of accident precursors; and suggested solutions to improve the reporting system of accident precursors. However, two main categories were found for not reporting individual reasons such as lack of commitment to the job, lack of attention to social responsibility, forgetfulness and laches in reporting, etc.; and organizational reasons such as job instability among employees, lack of sufficient training, failure of the organization to provide feedback, etc. Conclusion. This study found that the opinions of people working in the organization can be very effective in promoting reporting, so any organization can choose the appropriate strategy to increase the number and quality of reports by examining the opinions of managers, HSE officers and workers in the organization.Glutamic acid (Glu) is not only a protein amino acid, but also a signaling molecule, which takes part in various physiological processes in plants. Our previous study found that root-irrigation with Glu could improve the heat tolerance of maize seedlings by plant Glu receptor-like channels-mediated calcium signaling (Protoplasma, 2019; 2561165-1169), but its molecular mechanism remains unclear. In this study, based on the our previous work, the maize seedlings were treated with 1 mM Glu prior to be exposed to heat stress (HS), and then the expression of genes related to related to methylglyoxal (MG)-scavenging and osmoregulation systems was quantified. The results showed that Glu treatment up-regulated the gene expression of Zea mays aldo-keto reductase (ZmAKR) under both non-HS and HS conditions. Also, the gene expression of Zea mays alkenal/alkenone reductase (ZmAAR), glyoxalase II (ZmGly II), pyrroline-5-carboxylate synthase (ZmP5CS), betaine dehydrogenase (ZmBADH), and trehalase (ZmTRE) was up-regualted by exogenous Glu treatment under HS conditions. These data imply that signaling molecule Glu initiated the expression of genes related to MG-scavenging and osmoregulation systems in maize seedlings, further supporting the fact that Glu-enhanced heat tolerance in plants.Objectives. With the outbreak of coronavirus (COVID-19) about a year ago and its quick spread all around the world, some serious decisions had to be made like halting production temporarily. The world now tries to take back its normal pace thanks to some medical improvements. However, the 'new normal' is unlikely to follow the old habits in which COVID-19 never appeared. In production environments, a number of new precautions should be defined to prevent a spread of COVID-19 disease among employees in the new normal period. The aim of this study is to propose an analytical approach to define these new precautions and prioritize them. Methods. To determine the precautions, open archive publications of the Turkish Health Ministry and the World Health Organization, and the opinions of occupational physicians and academicians were considered. Twenty-five precautions were specified under three main headings. The Pythagorean fuzzy analytical hierarchy process was employed to gain the rank of precautions. Results. The most critical precautions and sub-precautions were determined as organizational precautions and developing an appropriate working model to ensure social distance. Conclusion. Using the determined order of measures, the managers are able to apply them, starting from the most effective ones.Possible changes in the morphology of the gills and liver of P. corruscans after exposure to TCF were evaluated. The fish were distributed into five groups in triplicate (n = 10 in each group 0.0; 0.125; 0.25; 0.5; 1.0 mg/L of the commercial product NEGUVON®, for 96 h. TCF induced a high histopathological index associated with circulatory disorders (congestion and aneurysm), as well as progressive changes (lamellar hyperplasia, capillary dilation, epithelial detachment and edema) at the highest concentrations (0.25; 0.5 and 1.0 mg/L). In addition to the histopathological disturbances, there was an increase in the levels of neutral glycoproteins and alterations in the histomorphometry of the secondary lamellae (total height, apical region, median, basal and interlamellar) at the highest concentrations. In the liver, the alterations were more intensified, in addition to circulatory (congestion) and regressive disturbances (loss of hepatocyte architecture and accumulation of intracellular substances), progressive alterations (focal necrosis) were observed, indicating a high degree of hepatic tissue involvement. The results indicate that the use of TCF concentrations above 0.25 mg/L promotes histopathological, histomorphometric and histochemical changes in the gills and liver of P. corruscans, imposing a biological risk that affects the aquatic environment and the health of fish.
The use of multi-sensory rooms as a form of engagement with art in Palliative Care is largely unexplored.
This practice-based report discusses a qualitative study exploring the experiences of hospice-based inpatients receiving end-of-life care and their carers who immersed themselves into a multi-sensory room.
Findings demonstrate that the room provided a safe space for reflection and reconnection that counteracted challenging times during their end of life. It fostered healing and wellbeing by alleviated suffering through respite and sharing of treasured memories with loved ones. Key considerations for future iterations are also discussed.

Growth factors are signalling molecules that play roles in the survival, proliferation, migration, and differentiation of cells. Studies have found alterations in specific growth factors in anorexia nervosa (AN).
This systematic review and meta-analysis examined articles from three databases, measuring growth factors in AN cross-sectionally and longitudinally, and in recovered AN (rec-AN) cross-sectionally. Random-effects meta-analyses were conducted for brain-derived neurotrophic factor (BDNF) and insulin growth factor-I (IGF-1) for cross-sectional and longitudinal studies.
A total of 82 studies were included 56 cross-sectional (BDNF
= 15; IGF-1
= 41) and 24 longitudinal (BDNF
= 5; IGF-1
= 19) were meta-analysed and 20 studies were narratively synthesised. In cross-sectional analyses, BDNF and IGF-1 were lower in AN compared to controls, and BDNF was marginally greater in rec-AN compared to controls. In longitudinal meta-analyses, BDNF and IGF-1 increased from baseline to follow-up. Cross-sectional subgroup analyses revealed no differences in BDNF between controls and AN binge-eating/purging subtypes.
It is likely that the low BDNF and IGF-1 levels found in AN are consequences of starvation, which are reversible with weight restoration. The increase in BDNF and IGF-1 during therapeutic weight restoration might improve neuroplasticity, which is the basis of learning, and thus psychotherapeutic success.

The main treatment for ST-elevation myocardial infarction (STEMI) is the re-establishment of the coronary flow of infarct-related arteries. However, 50% of cases present multivessel disease (MVD), negatively affecting mortality. Complete revascularization (CR) is currently advocated since it reduces major adverse cardiovascular events (MACE).
Evaluation of the adopted revascularization strategy and its prognostic value in a Portuguese cohort of STEMI patients with MVD.
Retrospective analysis of patients admitted with STEMI included in the Portuguese Registry of Acute Coronary Syndromes between 2010 and 2019. Patients were divided in two groups regarding revascularization strategy (complete versus incomplete) and compared. Independent predictors of a composite of all-cause mortality and rehospitalization for cardiovascular causes were assessed by multivariate logistic regression.
A total of 3500 patients were included. A CR strategy was performed in 21.8% of patients, who were younger and healthier. They also presented more hemodynamically stable and had less kidney dysfunction and anaemia.
