Role of Endocrine-Disrupting Chemicals in the Pathogenesis of Non-Alcoholic Fatty Liver Disease: A Comprehensive Review

Non-alcoholic fatty liver disease (NAFLD) is considered the most common liver disorder, affecting around 25% of the population worldwide. It is a complex disease spectrum, closely linked with other conditions such as obesity, insulin resistance, type 2 diabetes mellitus, and metabolic syndrome, which may increase liver-related mortality. In light of this, numerous efforts have been carried out in recent years in order to clarify its pathogenesis and create new prevention strategies. Currently, the essential role of environmental pollutants in NAFLD development is recognized. Particularly, endocrine-disrupting chemicals (EDCs) have a notable influence. EDCs can be classified as natural (phytoestrogens, genistein, and coumestrol) or synthetic, and the latter ones can be further subdivided into industrial (dioxins, polychlorinated biphenyls, and alkylphenols), agricultural (pesticides, insecticides, herbicides, and fungicides), residential (phthalates, polybrominated biphenyls, and bisphenol A), and pharmaceutical (parabens). Several experimental models have proposed a mechanism involving this group of substances with the disruption of hepatic metabolism, which promotes NAFLD. These include an imbalance between lipid influx/efflux in the liver, mitochondrial dysfunction, liver inflammation, and epigenetic reprogramming. It can be concluded that exposure to EDCs might play a crucial role in NAFLD initiation and evolution. However, further investigations supporting these effects in humans are required.
Comparative Study of Molecular Orbitals of Ruthenium (II) Chloride and Ruthenium (II) Iodide Based on Molecular Mechanics

We have studied the molecular orbitals of ruthenium halides, in order to study the extent of contribution of 4d, 5s and 5p orbitals in the formation of molecular orbitals. The 3D modeling and geometry optimization of the ruthenium halides have been done by CAChe software using molecular mechanics with EHT option. Eigenvector analysis shows that 4dx2- y2 and 4dxy orbitals of ruthenium play a major role in bonding between ruthenium and halogens, 5s orbital is next and 5p orbitals have a negligible role. There is a difference in energy levels of s and p orbitals of chloride and iodide are 0.1691 and 0.7472 respectively. The overlap population analysis shows that the nonbonding orbitals are present in 6th and 7th molecular orbitals in both. No molecular orbital is formed by only two atomic orbitals. All molecular orbitals have contribution from many atomic orbitals; the difference is only in extent of involvement.
High Performance PA 6/Cellulose Nanocomposites in the Interest of Industrial Scale Melt Processing

On an industrial scale, it is a challenge to achieve cellulose based nanocomposites due to dispersion issues and high process temperatures sensitivity. The current study describes methods to develop mechanically strong and thermally stable polyamide 6 (PA 6) and cellulose nanofibers (CNF) composites capable of tolerating high processing temperatures. With PA 6 being a very technical polymer matrix to be reinforced with CNF, good dispersion can be achieved with a high speed kinetic mixer and also shield the CNF from excess thermal degradation by implementing extremely short processing time. This paper presents an industrially feasible method to produce PA 6/CNF nanocomposites with high CNF composition processed by a high speed kinetic mixer (GELIMAT®) followed by compression molding to obtain a homogenous and thermally stable nanocomposites aimed at high performance applications. PA 6 was reinforced with three different wt % formulations (5, 15 and 25 wt %) of cellulose nanofibers. The resulting nanocomposites exhibited significant increase in Young’s modulus and ultimate strength with CNF content, owing to the effective melt processing and the surface charge density of the CNF, which necessitated the dispersion. The thermal stability and polymer crystallinity with respect to CNF composition for the PA 6/CNF nanocomposites were examined by TGA and DSC analysis. Rheology studies indicated that viscosity of the composites increased with increase in CNF composition. Overall, this work demonstrates industrially viable manufacturing processes to fabricate high performance PA 6/CNF nanocomposites.
Epigenetics, microRNA and Metabolic Syndrome: A Comprehensive Review

Epigenetics refers to the DNA chemistry changes that result in the modification of gene transcription and translation independently of the underlying DNA coding sequence. Epigenetic modifications are reported to involve various molecular mechanisms, including classical epigenetic changes affecting DNA methylation and histone modifications and small RNA-mediated processes, particularly that of microRNAs. Epigenetic changes are reversible and are closely interconnected. They are recognised to play a critical role as mediators of gene regulation, and any alteration in these mechanisms has been identified to mediate various pathophysiological conditions. Moreover, genetic predisposition and environmental factors, including dietary alterations, lifestyle or metabolic status, are identified to interact with the human epigenome, highlighting the importance of epigenetic factors as underlying processes in the aetiology of various diseases such as MetS. This review will reflect on how both the classical and microRNA-regulated epigenetic changes are associated with the pathophysiology of metabolic syndrome. We will then focus on the various aspects of epigenetic-based strategies used to modify MetS outcomes, including epigenetic diet, epigenetic drugs, epigenome editing tools and miRNA-based therapies.
Assessment of Home-Based and Mobility-Based Exposure to Black Carbon in an Urban Environment: A Pilot Study

The combustion of fossil fuels is a significant source of particulate-bound black carbon (BC) in urban environments. The personal exposure (PE) of urban dwellers to BC and subsequent health impacts remain poorly understood due to a lack of observational data. In this study, we assessed and quantified the levels of PE to BC under two exposure scenarios (home-based and mobility-based exposure) in the city of Trivandrum in India. In the home-based scenario, the PE to BC was assessed in a naturally ventilated building over 24 h each day during the study period while in the mobility-based scenario, the PE to BC was monitored across diverse microenvironments (MEs) during the day using the same study protocol for consistency. Elevated BC concentrations were observed during the transport by motorcycle (26.23 ± 2.33 µg/m3) and car (17.49 ± 2.37 µg/m3). The BC concentrations observed in the MEs decreased in the following order: 16.58 ± 1.38 µg/m3 (temple), 13.78 ± 2.07 µg/m3 (restaurant), 11.44 ± 1.37 µg/m3 (bus stop), and 8.27 ± 1.88 µg/m3 (home); the standard deviations represent the temporal and spatial variations of BC concentrations. Overall, a relatively larger inhaled dose of BC in the range of 148.98–163.87 µg/day was observed for the mobility-based scenario compared to the home-based one (118.10–137.03 µg/day). This work highlights the importance of reducing PE to fossil fuel-related particulate emissions in cities for which BC is a good indicator. The study outcome could be used to formulate effective strategies to improve the urban air quality as well as public health.
1 The application of catalytic processes on the 2 production of algae-based biofuels : a review 3

11 Abstract: Over the last decades, microalgal biomass has gained a significant role in the 12 development of different high-end (nutraceuticals, colorants, food supplements, and 13 pharmaceuticals) and low-end products (biodiesel, bioethanol, and biogas) due to rapid growth and 14 high carbon fixing efficiency. Therefore, microalgae are considered a useful and sustainable resource 15 to attain energy security while reducing our current reliance on fossil fuels. From the technologies 16 available for obtaining biofuels using microalgae biomass, thermochemical processes (pyrolysis, 17 HTL, gasification) have proven to be processed with higher viability, because they use all biomass. 18 However, because of the complexity of the biomass (lipids, carbohydrates , and proteins), the 19 obtained biofuels from direct thermochemical conversion have large amounts of heteroatoms 20 (oxygen, nitrogen , and sulfur). As a solution, catalyst-based processes have emerged as a sustainable 21 solution for the increase in biocrude production. This paper's objective is to present a comprehensive 22 review of recent developments on catalyst mediated conversion of algal biomass. Special attention 23 will be given to operating conditions, strains evaluated, and challenges for the optimal yield of algal24 based biofuels through pyrolysis and HTL. 25
Perinatal Exposure to Phthalates: From Endocrine to Neurodevelopment Effects

Phthalates, as other endocrine disrupting chemicals (EDCs), may alter the homeostasis and the action of hormones and signaling molecules, causing adverse health outcomes. This is true especially for infants, who are both more exposed and sensitive to their effects. Phthalates are particularly harmful when the exposure occurs during certain critical temporal windows of the development, such as the prenatal and the early postnatal phases. Phthalates may also interfere with the neuroendocrine systems (e.g., thyroid hormone signaling or metabolism), causing disruption of neuronal differentiation and maturation, increasing the risk of behavioral and cognitive disorders (ADHD and autistic behaviors, reduced mental, psychomotor, and IQ development, and emotional problems). Despite more studies being needed to better understand the role of these substances, plenty of evidence suggests the impact of phthalates on the neuroendocrine system development and function. This review aims to update the knowledge on the neuroendocrine consequences of neonatal and perinatal exposure to phthalates.
Effects of Sacubitril/Valsartan on Serum Lipids in Heart Failure With Preserved Ejection Fraction

Background Dyslipidemia is common in heart failure with preserved ejection fraction. Sacubitril/valsartan improves glycemic control and augments natriuretic peptide signaling, providing mechanisms by which sacubitril/valsartan may affect serum lipids. However, empiric data on these effects are lacking. Methods and Results We analyzed 4774 participants from PARAGON‐HF (Prospective Comparison of Angiotensin Receptor–Neprilysin Inhibitor With Angiotensin‐Receptor Blockers Global Outcomes in Heart Failure With Preserved Ejection Fraction) with available screening lipids. During follow‐up visits, we analyzed the treatment effect on lipid levels and assessed for interaction by baseline lipid levels. At the 16‐week visit, we adjusted these treatment effects for the change in several biomarkers (including hemoglobin A1c and urinary cyclic guanosine monophosphate/creatinine [a biomarker of natriuretic peptide activation]). The average age was 73±8 years, 52% were women, 43% had diabetes mellitus, and 64% were on statin therapy. Compared with valsartan, sacubitril/valsartan reduced triglycerides −5.0% (95% CI, −6.6% to −3.5%), increased high‐density lipoprotein cholesterol +2.6% (95% CI, +1.7% to +3.4%), and increased low‐density lipoprotein cholesterol +1.7% (95% CI, +0.4% to +3.0%). Sacubitril/valsartan reduced triglycerides most among those with elevated baseline levels (triglycerides≥200 mg/dL) (P‐interaction<0.001), and at 16 weeks by −13.0% (95% CI, −18.1% to −7.6%), or −29.9 (95% CI, −44.3 to −15.5) mg/dL, in this group. Adjusting for the change in urinary cyclic guanosine monophosphate/creatinine significantly attenuated treatment effects on triglycerides and high‐density lipoprotein cholesterol, but not low‐density lipoprotein cholesterol, while adjusting for other biomarkers did not significantly alter the treatment effects. Conclusions Sacubitril/valsartan significantly reduces triglycerides compared with valsartan, an effect that was nearly threefold stronger in those with elevated baseline triglycerides. Modest increases in high‐density lipoprotein cholesterol and low‐density lipoprotein cholesterol cholesterol were also observed with therapy. The underlying mechanism(s) of changes in high‐density lipoprotein cholesterol and triglycerides are related to sacubitril/valsartan’s effects on natriuretic peptide activity.

Layered Double Hydroxides-Based Materials as Oxidation Catalysts

Layered double hydroxides (LDHs) belong to the anionic clays family having the general formula M M (OH) A mH O 1 x II x III 2 x/n n 2 − − ⋅ with 0.2 ≤ x ≤ 0.4 corresponding to a MII/MIII molar ratio between 1.5 and 4 (Tichit & Coq, 2003). MII and MIII are bivalent and trivalent cations, respectively, with ionic radii not too different from that of Mg2+ (Cavani et al., 1991). They are hexa-coordinated to hydroxyl groups forming brucite-like sheets which stack to create a layered structure. Counter-anions An– are intercalated in the inter-layer space to compensate the positive charge introduced by the MIII cations partially replacing MII cations in the layers. Two or more cations can enter simultaneously the brucite-like sheets where they are homogeneously distributed and intimately mixed together. Notably, the LDHs can be easily prepared by coprecipitation at a pH higher than or equal to the one at which the more soluble hydroxide precipitates (Cavani et al., 1991). At the same time, a large variety of inorganic and organic anions can be intercalated between the layers, mainly by a simple anionic exchange procedure. Due to their structure, together with their compositional flexibility, the LDHs possess versatile physico-chemLayered Double HydroxidesBased Materials as Oxidation Catalysts
Diagnostic Thresholds for Pre–Diabetes Mellitus and Diabetes Mellitus and Subclinical Cardiac Disease in the General Population: Data From the ACE 1950 Study

Background Diabetes mellitus (DM) is associated with left ventricular remodeling and incident heart failure, but the association between glycated hemoglobin A1c (HbA1c) and subclinical cardiac disease is not established. We aimed to determine the associations between HbA1c and (1) echocardiographic measures of left ventricular structure and function, and (2) cardiovascular biomarkers: cardiac troponin T, NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide), and CRP (C‐reactive protein). Methods and Results Participants (n=3688) born in 1950 from the population‐based ACE (Akershus Cardiac Examination) 1950 Study were classified as DM (HbA1c≥6.5% or self‐reported DM), pre‐DM (HbA1c 5.7%–6.5%), and no‐DM (HbA1c<5.7%). DM, pre‐DM, and no‐DM were classified in 380 (10%), 1630 (44%), and 1678 (46%) participants, respectively. Mean age was 63.9±0.7 years, mean body mass index was 27.2±4.4 kg/m2, and 49% were women. Higher HbA1c was associated with worse left ventricular systolic (ejection fraction and global longitudinal strain) and diastolic (E/e'‐ratio) function, myocardial injury (cardiac troponin T), inflammation (CRP), and impaired neurohormonal homeostasis (NT‐proBNP) (P<0.001 in unadjusted and P<0.01 in adjusted analysis for all). The associations between HbA1c and cardiovascular biomarkers were independent of the echocardiographic variables, and vice versa. Associations were nonlinear (P<0.05 for nonlinearity) and appeared stronger in the pre‐DM range of HbA1c than the no‐DM and DM range. Conclusions HbA1c was associated with indexes of subclinical cardiovascular disease, and this was more pronounced in pre‐DM. Our results suggest that cardiovascular preventive measures should be considered also in subjects with hyperglycemia and HbA1c below the established DM cutoff. Registration clinicaltrials.gov.

Electromyography-informed modeling for estimating muscle activation and force alterations in Parkinson’s disease

Abstract Electromyography (EMG)-driven neuromusculoskeletal modeling (NMSM) enables simulating the mechanical function of multiple muscle-tendon units as controlled by nervous system in the generation of complex movements. In the context of clinical assessment this may enable understanding biomechanical factor contributing to gait disorders such as one induced by Parkinson’s disease (PD). In spite of the challenges in the development of patient-specific models, this preliminary study aimed at establishing a feasible and noninvasive experimental and modeling pipeline to be adopted in clinics to detect PD-induced gait alterations. Four different NMSM have been implemented for three healthy controls using CEINMS, an OpenSim-compatible toolbox. Models differed in the EMG-normalization methods used for calibration purposes (i.e. walking trial normalization and maximum voluntary contraction normalization) and in the set of experimental EMGs used for the musculotendon-unit mapping (i.e. 4 channels vs. 15 channels). Model accuracy assessment showed no statistically significant differences between the more complete model (non-clinically viable) and the proposed reduced one (clinically viable). The clinically viable reduced model was systematically applied on a dataset including ten PD’s and thirteen healthy controls. Results showed significant differences in the neuromuscular control strategy of the PD group in term of muscle forces and joint torques. Indeed, PD patients displayed a significantly lower magnitude on force production and revealed a higher amount of force variability with the respect of the healthy controls. The estimated variables could become a measurable biomechanical outcome to assess and track both disease progression and its impact on gait in PD subjects.
Hydraulically‐vulnerable trees survive on deep‐water access during droughts in a tropical forest

Summary Deep‐water access is arguably the most effective, but under‐studied, mechanism that plants employ to survive during drought. Vulnerability to embolism and hydraulic safety margins can predict mortality risk at given levels of dehydration, but deep‐water access may delay plant dehydration. Here, we tested the role of deep‐water access in enabling survival within a diverse tropical forest community in Panama using a novel data‐model approach. We inversely estimated the effective rooting depth (ERD, as the average depth of water extraction), for 29 canopy species by linking diameter growth dynamics (1990–2015) to vapor pressure deficit, water potentials in the whole‐soil column, and leaf hydraulic vulnerability curves. We validated ERD estimates against existing isotopic data of potential water‐access depths. Across species, deeper ERD was associated with higher maximum stem hydraulic conductivity, greater vulnerability to xylem embolism, narrower safety margins, and lower mortality rates during extreme droughts over 35 years (1981–2015) among evergreen species. Species exposure to water stress declined with deeper ERD indicating that trees compensate for water stress‐related mortality risk through deep‐water access. The role of deep‐water access in mitigating mortality of hydraulically‐vulnerable trees has important implications for our predictive understanding of forest dynamics under current and future climates.
Using mobile brain/body imaging to advance research in arts, health, and related therapeutics

The uses of mobile brain/body imaging (MoBI) are expanding and allow for more direct study of the neurophysiological signals associated with behavior in psychotherapeutic encounters. Neuroaesthetics is concerned with the cognitive and neural basis of art appreciation, and scientific correlations are being made in the field that might help to clarify theories claimed in the creative arts therapies. Yet, most neuroaesthetics studies are confined to the laboratory and do not propose a translation for research methods and clinical applications. The creative arts therapies have a long history of clinical success with various patient populations and will benefit from increased scientific explanation to support intervention strategies. Examining the brain dynamics and motor behaviors that are associated with the higher complex processes involved in artistic expression offers MoBI as a promising instrumentation to move forward in linking ideas from neuroaesthetics to the creative arts therapies. Tracking brain dynamics in association with behavioral change allows for more objective and quantitative physiological monitors to evaluate, and together with subjective patient reports provides insight into the psychological mechanisms of change in treatment. We outline a framework that shows how MoBI can be used to study the effectiveness of creative arts therapy interventions motivated by the 4E approach to cognition with a focus on visual art therapy. The article illuminates how a new partnership among the fields of art therapy, neuroscience, and neuroaesthetics might work together within the 4E/MoBI framework in efforts to advance transdisciplinary research for clinical health populations.
Multivessel PCI Guided by FFR or Angiography for Myocardial Infarction.

BACKGROUND In patients with ST-elevation myocardial infarction (STEMI) who have multivessel disease, percutaneous coronary intervention (PCI) for nonculprit lesions (complete revascularization) is superior to treatment of the culprit lesion alone. However, whether complete revascularization that is guided by fractional flow reserve (FFR) is superior to an angiography-guided procedure is unclear. METHODS In this multicenter trial, we randomly assigned patients with STEMI and multivessel disease who had undergone successful PCI of the infarct-related artery to receive complete revascularization guided by either FFR or angiography. The primary outcome was a composite of death from any cause, nonfatal myocardial infarction, or unplanned hospitalization leading to urgent revascularization at 1 year. RESULTS The mean (±SD) number of stents that were placed per patient for nonculprit lesions was 1.01±0.99 in the FFR-guided group and 1.50±0.86 in the angiography-guided group. During follow-up, a primary outcome event occurred in 32 of 586 patients (5.5%) in the FFR-guided group and in 24 of 577 patients (4.2%) in the angiography-guided group (hazard ratio, 1.32; 95% confidence interval, 0.78 to 2.23; P = 0.31). Death occurred in 9 patients (1.5%) in the FFR-guided group and in 10 (1.7%) in the angiography-guided group; nonfatal myocardial infarction in 18 (3.1%) and 10 (1.7%), respectively; and unplanned hospitalization leading to urgent revascularization in 15 (2.6%) and 11 (1.9%), respectively. CONCLUSIONS In patients with STEMI undergoing complete revascularization, an FFR-guided strategy did not have a significant benefit over an angiography-guided strategy with respect to the risk of death, myocardial infarction, or urgent revascularization at 1 year. However, given the wide confidence intervals for the estimate of effect, the findings do not allow for a conclusive interpretation.

Verbal and spatial memory spans in mild cognitive impairment

Working memory (WM) for verbal and visual material may be affected early in individuals with mild cognitive impairment (MCI). Verbal and visuospatial span tasks, that is neuropsychological procedures commonly used for the clinical assessment of WM, have been scarcely investigated in these patients. Therefore, this study was aimed at evaluating whether performance on tests of verbal and visual‐spatial span (which rely to different extents on distinct components of the WM system) is differently sensitive to the presence of MCI and, in particular, of a preclinical AD condition in patients with MCI.
