Damage of the swarmer Pseudomonas soil isolate cell by UVc as revealed by transmission electron microscopy

ABSTRACT The modeling of the response of living organisms to a change in environment is an important issue of current interest. An example is the effect of ultraviolet radiation on biological systems. In this paper, molecular and analytical identification of Pseudomonas isolate were reported. Then, swarmer Pseudomonas cells were exposed to UVc radiations. The spatiotemporal response of swarmer Pseudomonas, to UVc exposure, was followed. Observing alterations in bacterial membrane integrity by electron microscopy can help to clarify the detailed mechanisms of resistance to UVc. The most evident changes were related to membrane structures. In the cytoplasm, the main finding was the appearance of round mesosomes as intracellular bilayered membranes. Another impact of UVc on Pseudomonas was evident from the appearance of additional membrane structures. In accordance with the viability results, UVc-induced ultrastructural changes of Pseudomonas membrane structures were identified, resulting in cell death, through a multistage model of UVc inactivation.
The Mediating Role of Cardiometabolic Dysregulation on the Relation Between Adverse Childhood Experiences and Adult Cognition

ABSTRACT Objective Adverse childhood experiences (ACEs) are uncontrollable stressful events during early life that predispose adults to adverse health outcomes, such as impaired cognitive functioning. However, little is known about the factors indirectly impacting this relation. Biological dysregulation may be one pathway that can help explain the relations between ACEs and later cognition. The current study examined the mediating role of cardiometabolic dysregulation on the relation between ACEs and cognition. Methods Our study gathered data from 1053 participants using three waves of the Midlife in the United States longitudinal study. Linear regression analyses and bootstrapped mediation analyses were performed to analyze the direct and indirect associations of cardiometabolic dysregulation on ACEs and cognition. Results Our results showed a significant linear relationship between ACEs and cardiometabolic dysregulation (b = 0.152, standard error [SE] = 0.056, p = .007), and a significant indirect association, such that cardiometabolic dysregulation mediated the relation between ACEs and cognitive status at wave II (b = −0.007, SE = 0.004, p = .044) and cognitive status at wave III (b = −0.006, SE = 0.003, p .042). There was no significant direct or indirect relation when cognitive change was the outcome variable. Conclusions The present study identifies a combined biological pathway that connects ACEs to cognition in late life. These findings supports the need to empirically determine biological mechanism that can be used to develop targeted clinical interventions to prevent the progression of chronic cognitive impairment.
The role of long non-coding RNA FGD5-AS1 in cancer

ABSTRACT Long noncoding RNAs (lncRNAs) refers to a class of RNAs that have at least 200 nucleotides and do not encode proteins, and the relationship between lncRNA and cancer has recently attracted considerable research attention. The lncRNA FGD5-AS1 is a newly discovered lncRNA with a length of 3772 nucleotides. Studies have found that FGD5-AS1 is abnormally highly expressed in many cancer tissues and was closely related to the lymph node metastasis, tumor invasion, survival time, and recurrence rate of various cancers. Mechanistic analyses show that FGD5-AS1 can stabilize mRNA expression by sponging miRNA, which not only induces cancer cell proliferation, metastasis, invasion, and chemoresistance in vitro, but also promotes tumor growth and metastasis in vivo. In addition, FGD5-AS1 can serve as a diagnostic or prognostic marker for a variety of cancers. This review demonstrates the clinical significance of FGD5-AS1 in human cancer and its role in tumorigenesis and tumor progression. Graphical abstract
Developmental trajectory of magnetic susceptibility in the healthy rhesus macaque brain

Quantitative susceptibility mapping (QSM) is used to quantify iron deposition in non‐human primates in our study. Although QSM has many applications in detecting iron deposits in the human brain, including the distribution of iron deposits in specific brain regions, the change of iron deposition with aging, and the comparison of iron deposits between diseased groups and healthy controls, few studies have applied QSM to non‐human primates, while most animal brain experiments focus on biochemical and anatomical results instead of non‐invasive experiments. Additionally, brain imaging in children's research is difficult, but can be substituted using young rhesus monkeys, which are very similar to humans, as research animals. Therefore, understanding the relationship between iron deposition and age in rhesus macaques' brains can offer insights into both the developmental trajectory of magnetic susceptibility in the animal model and the correlated evidence in children's research. Twenty‐three healthy rhesus macaque monkeys (23 ± 7.85 years, range 2–29 years) were included in this research. Seven regions of interest (ROIs—globus pallidus, substantia nigra, dentate nucleus, caudate nucleus, putamen, thalamus, red nucleus) have been analyzed in terms of QSM and R2* (apparent relaxation rate). Susceptibility in most ROIs correlated significantly with the growth of age, similarly to the results for R2*, but showed different trends in the thalamus and red nucleus, which may be caused by the different sensitivities of myelination and iron deposition in R2* and QSM analysis. By assessing the correlation between iron content and age in healthy rhesus macaques' brains using QSM, we provide a piece of pilot information on normality for advanced animal disease models. Meanwhile, this study also could serve as the normative basis for further clinical studies using QSM for iron content quantification. Due to the comparison of the susceptibility on the same experimental objects, this research can also provide practical support for future research on characteristics for QSM and R2*.
New-Onset Atrial Fibrillation in Patients Hospitalized With COVID-19: Results From the American Heart Association COVID-19 Cardiovascular Registry

Background: New-onset atrial fibrillation (AF) in patients hospitalized with COVID-19 has been reported and associated with poor clinical outcomes. We aimed to understand the incidence of and outcomes associated with new-onset AF in a diverse and representative US cohort of patients hospitalized with COVID-19. Methods: We used data from the American Heart Association COVID-19 Cardiovascular Disease Registry. Patients were stratified by the presence versus absence of new-onset AF. The primary and secondary outcomes were in-hospital mortality and major adverse cardiovascular events (MACE; cardiovascular death, myocardial infarction, stroke, cardiogenic shock, and heart failure). The association of new-onset AF and the primary and secondary outcomes was evaluated using Cox proportional-hazards models for the primary time to event analyses. Results: Of the first 30 999 patients from 120 institutions across the United States hospitalized with COVID-19, 27 851 had no history of AF. One thousand five hundred seventeen (5.4%) developed new-onset AF during their index hospitalization. New-onset AF was associated with higher rates of death (45.2% versus 11.9%) and MACE (23.8% versus 6.5%). The unadjusted hazard ratio for mortality was 1.99 (95% CI, 1.81–2.18) and for MACE was 2.23 (95% CI, 1.98–2.53) for patients with versus without new-onset AF. After adjusting for demographics, clinical comorbidities, and severity of disease, the associations with death (hazard ratio, 1.10 [95% CI, 0.99–1.23]) fully attenuated and MACE (hazard ratio, 1.31 [95% CI, 1.14–1.50]) partially attenuated. Conclusions: New-onset AF was common (5.4%) among patients hospitalized with COVID-19. Almost half of patients with new-onset AF died during their index hospitalization. After multivariable adjustment for comorbidities and disease severity, new-onset AF was not statistically significantly associated with death, suggesting that new-onset AF in these patients may primarily be a marker of other adverse clinical factors rather than an independent driver of mortality. Causality between the MACE composites and AF needs to be further evaluated.
COVID-19 vaccine acceptance and hesitancy among ethnic minorities in Hong Kong

ABSTRACT Ethnic minorities account for 8% of the Hong Kong population, most are Filipino and Indonesian domestic helpers taking care of children and the elderly. To understand the COVID-19 vaccination rates and factors associated with vaccine acceptance of ethnic minorities, we performed a cross-sectional questionnaire study recruiting Hong Kong ethnic minorities aged ≥18 years between 1 July and 18 July 2021 in public areas. Demographics, knowledge about COVID-19, vaccination status, intention and reasons to receive the vaccine, and planning to be re-vaccinated were analyzed. Continuous and categorical variables were compared using unpaired t-test and Chi-square test, respectively. Potential confounders were adjusted using multiple logistic regression. 2,012 ethnic minorities participated, with a mean age of 39 years, of which 97.6% were female, 79.5% were Filipino, and 17.5% were Indonesian. 80.6% of participants were categorized as vaccine acceptance, and 69.2% were willing to be re-vaccinated. There were significantly more Filipinos than Indonesians in the vaccine acceptance group (p < .001). Subjects in the vaccine acceptance group were more likely to have higher education (p < .001), a higher COVID-19 knowledge score (p < .001), received information from the Government website (p = .003) and not from their friends or family members (p = .02), and were more confident in judging the accuracy of the information (p < .001). Logistic regression showed the mean knowledge score (β = 3.07, p < .001) and receiving information from official Government websites (adjusted OR = 1.37, p = .03) were significant factors that positively influenced vaccine acceptance. The Hong Kong Government should improve COVID-19 vaccination acceptance among ethnic minorities through public education using official channels.
Physical performance of adaptive axial FOV PET scanners with a sparse detector block rings or a checkerboard configuration

Objective. Using Monte-Carlo simulations, we evaluated the physical performance of a hypothetical state-of-the-art clinical PET scanner with adaptive axial field-of-view (AFOV) based on the validated GATE model of the Siemens Biograph VisionTM PET/CT scanner. Approach. Vision consists of 16 compact PET rings, each consisting of 152 mini-blocks of 5 × 5 Lutetium Oxyorthosilicate crystals (3.2 × 3.2 × 20 mm3). The Vision 25.6 cm AFOV was extended by adopting (i) a sparse mini-block ring (SBR) configuration of 49.6 cm AFOV, with all mini-block rings interleaved with 16 mm axial gaps, or (ii) a sparse mini-block checkerboard (SCB) configuration of 51.2 cm AFOV, with all mini-blocks interleaved with gaps of 16 mm (transaxial) × 16 mm (axial) width in checkerboard pattern. For sparse configurations, a ‘limited’ continuous bed motion (limited-CBM) acquisition was employed to extend AFOVs by 2.9 cm. Spatial resolution, sensitivity, image quality (IQ), NECR and scatter fraction were assessed per NEMA NU2-2012. Main Results. All IQ phantom spheres were distinguishable with all configurations. SBR and SCB percent contrast recovery (% CR) and background variability (% BV) were similar (p-value > 0.05). Compared to Vision, SBR and SCB %CRs were similar (p-values > 0.05). However, SBR and SCB %BVs were deteriorated by 30% and 26% respectively (p-values < 0.05). SBR, SCB and Vision exhibited system sensitivities of 16.6, 16.8, and 15.8 kcps MBq−1, NECRs of 311 kcps @35 kBq cc−1, 266 kcps @25.8 kBq cc−1, and 260 kcps @27.8 kBq cc−1, and scatter fractions of 31.2%, 32.4%, and 32.6%, respectively. SBR and SCB exhibited a smoother sensitivity reduction and noise enhancement rate from AFOV center to its edges. SBR and SCB attained comparable spatial resolution in all directions (p-value > 0.05), yet, up to 1.5 mm worse than Vision (p-values < 0.05). Significance. The proposed sparse configurations may offer a clinically adoptable solution for cost-effective adaptive AFOV PET with either highly-sensitive or long-AFOV acquisitions.
Valorization of olive processing by-products via drying technologies: a case study on the recovery of bioactive phenolic compounds from olive leaves, pomace, and wastewater

Abstract Olive by-products are rich sources of phenolic compounds and their valorization is a favorable approach in line with sustainable development goals of the United Nations (UN) organization to promote well-being and production of healthier products; also, to deal with the environmental and economic subjects resulting in more profitability in the olive oil industry. The production of value-added ingredients from these by-products is not extensively exploited on the industrial scale. Drying is a critical pretreatment before extraction that can have a direct impact on the recovery and yield of the available bioactive compounds in olive by-products. In order to produce more stable and high quality phenolic products, encapsulation using spray and freeze drying is used. In this study, the effect of the drying process before and after extraction of bioactive compounds from olive by-products as a valuable source of phenolic compounds is reviewed. In addition, fortification using these ingredients and their incorporation in food formulations is also investigated.
A controlled chamber study of effects of exposure to diesel exhaust particles and noise on heart rate variability and endothelial function

Abstract Background Adverse cardiovascular effects are associated with both diesel exhaust and road traffic noise, but these exposures are hard to disentangle epidemiologically. We used an experimental setup to evaluate the impact of diesel exhaust particles and traffic noise, alone and combined, on intermediary outcomes related to the autonomic nervous system and increased cardiovascular risk. Methods In a controlled chamber 18 healthy adults were exposed to four scenarios in a randomized cross-over fashion. Each exposure scenario consisted of either filtered (clean) air or diesel engine exhaust (particle mass concentrations around 300 µg/m3), and either low (46 dB(A)) or high (75 dB(A)) levels of traffic noise for 3 h at rest. ECG was recorded for 10-min periods before and during each exposure type, and frequency-domain heart rate variability (HRV) computed. Endothelial dysfunction and arterial stiffness were assessed after each exposure using EndoPAT 2000. Results Compared to control exposure, HRV in the high frequency band decreased during exposure to diesel exhaust, both alone and combined with noise, but not during noise exposure only. These differences were more pronounced in women. We observed no synergistic effects of combined exposure, and no significant differences between exposure scenarios for other HRV indices, endothelial function or arterial stiffness. Conclusion Three-hour exposure to diesel exhaust, but not noise, was associated with decreased HRV in the high frequency band. This indicates activation of irritant receptor-mediated autonomic reflexes, a possible mechanism for the cardiovascular risks of diesel exposure. There was no effect on endothelial dysfunction or arterial stiffness after exposure.
Type 1 melanocortin receptors in pro‐opiomelanocortin‐, vasopressin‐, and oxytocin‐immunopositive neurons in different areas of mouse brain

Information on the localization of the Type 1 melanocortin receptors (MC1Rs) in different regions of the brain is very scarce. As a result, the role of MC1Rs in the functioning of brain neurons and in the central regulation of physiological functions has not been studied. This work aimed to study the expression and distribution of MС1Rs in different brain areas of female C57Bl/6J mice. Using real‐time polymerase chain reaction, we demonstrated the Mс1R gene expression in the cerebral cortex, midbrain, hypothalamus, medulla oblongata, and hippocampus. Using an immunohistochemical approach, we showed the MС1R localization in neurons of the hypothalamic arcuate, paraventricular and supraoptic nuclei, nucleus tractus solitarius (NTS), dorsal hippocampus, substantia nigra, and cerebral cortex. Using double immunolabeling, the MC1Rs were visualized on the surface and in the bodies and outgrowths of pro‐opiomelanocortin (POMC)‐immunopositive neurons in the hypothalamic arcuate nucleus, NTS, hippocampal CA3 and CA1 regions, and cerebral cortex. Co‐localization with POMC indicates that MC1R, like MC3R, is able to function as an autoreceptor. In the paraventricular and supraoptic nuclei, MC1Rs were visualized on the surface and in the cell bodies of vasopressin‐ and oxytocin‐immunopositive neurons, indicating a relationship between hypothalamic MC1R signaling and vasopressin and oxytocin production. The data obtained indicate a wide distribution of MC1Rs in different areas of the mouse brain and their localization in POMC‐, vasopressin‐ and oxytocin‐immunopositive neurons, which may indicate the participation of MC1Rs in the control of many physiological processes in the central nervous system.
International High-Performance Built Environment Conference – A Sustainable Built Environment Conference 2016 Series ( SBE 16 ) , iHBE 2016 The Carbon Footprint of Australia ’ s Construction Sector

Australia accounts for just 0.33% of the world’s population yet it is one of the highest emitters of greenhouse gas (GHG) emissions per capita in the world. The construction sector is a substantial area for mitigation efforts in Australia because of its economic importance and its involvement with indirect GHG emissions, i.e. those embodied in construction supply chains, including construction materials and electricity use. While the majority of policies and regulations focus on reducing direct emissions from buildings, more attention needs to be paid to the embodied emissions of the whole sector as these can take up anywhere between 10% and 97% of the whole life-cycle carbon emissions. This study aims at unravelling the total carbon footprint of the construction sector in Australia from 2009 to 2013, identifying the key contributing supply chains, industries and products. An economy wide input-output (IO) analysis is performed using a collaborative, cloud-based data platform – the Industrial Ecology Virtual Laboratory (IELab). This allows for a detailed disaggregation of sectors and permits more refined analysis as well as benchmarking against other sectors in the economy. Results for CO2e emissions by final demand show the construction sector makes up 18.1% of Australia’s carbon footprint, compared to only 1.9% of direct emissions in 2013. The largest contributors to these embodied emissions are electricity, water & waste and materials throughout the years. Results are also broken down by detailed construction activities in residential / nonresidential, road & bridge, other heavy and civil engineering and construction services. Mitigation options for electricity supply and materials use in the Australian construction sector are suggested. © 2017 The Authors. Published by Elsevier Ltd.

Instagram Use Among Orthopaedic Surgery Residency Programs

Introduction: The COVID-19 pandemic created unprecedented challenges to residency recruitment. With in-person away rotations prohibited and interviews held virtually, orthopaedic residency programs turned to social media. Studies document the exponential growth of residency program Instagram accounts after March 2020, but few analyze the content of their posts. This study provides an updated assessment of such Instagram accounts including a detailed analysis of their content and a discussion of potentially concerning posts. Methods: Orthopaedic surgery residency programs participating in the National Resident Matching Program and any Instagram accounts associated with these programs were identified. Instagram accounts were analyzed, and the 25 most recent posts and all highlighted stories for each account were coded for content based on a predetermined list of categories. Specific attention was given to content that may raise legal, ethical, or professionalism concerns. The primary outcome was the most common content code among posts. The secondary outcomes were the number of posts identified as potentially concerning and the types of concerns represented. Results: Overall, 138 of 193 residency programs (72%) had an Instagram account at the time of cross-sectional analysis, 65% of which were created between April and December 2020. All accounts were public. Profiles had on average 1,156 ± 750 followers and 59 ± 75 posts. Of the 3,348 posts analyzed, the most common coded themes were resident introductions (33%), camaraderie (27%), and social life and hobbies (26%). There were 81 concerning posts from 52 separate accounts. Seventy-five of the concerning posts (93%) depicted residents scrubbed alone. Conclusion: Orthopaedic residency Instagram accounts are potential tools for residency recruitment and can depict a program's culture through posts over time. However, public accounts are open to scrutiny by other viewers, including patients and their families. Care must be taken to consider multiple perspectives of post content, so as to bolster, not damage, the residency program's reputation.
Down‐phase auditory stimulation is not able to counteract pharmacologically or physiologically increased sleep depth in traumatic brain injury rats

Modulation of slow‐wave activity, either via pharmacological sleep induction by administering sodium oxybate or sleep restriction followed by a strong dissipation of sleep pressure, has been associated with preserved posttraumatic cognition and reduced diffuse axonal injury in traumatic brain injury rats. Although these classical strategies provided promising preclinical results, they lacked the specificity and/or translatability needed to move forward into clinical applications. Therefore, we recently developed and implemented a rodent auditory stimulation method that is a scalable, less invasive and clinically meaningful approach to modulate slow‐wave activity by targeting a particular phase of slow waves. Here, we assessed the feasibility of down‐phase targeted auditory stimulation of slow waves and evaluated its comparative modulatory strength in relation to the previously employed slow‐wave activity modulators in our rat model of traumatic brain injury. Our results indicate that, in spite of effectively reducing slow‐wave activity in both healthy and traumatic brain injury rats via down‐phase targeted stimulation, this method was not sufficiently strong to counteract the boost in slow‐wave activity associated with classical modulators, nor to alter concomitant posttraumatic outcomes. Therefore, the usefulness and effectiveness of auditory stimulation as potential standalone therapeutic strategy in the context of traumatic brain injury warrants further exploration.
