Chemistry and Composition of Planetary Atmospheres

This chapter summarizes atmospheric chemistry and composition for the seven planets in our solar system that have significant atmospheres. The terrestrial planets (Venus, Earth, and Mars) have secondary atmospheres that originated by the outgassing of volatile-rich material during and/or after planetary accretion. The gas giant planets (Jupiter, Saturn, Uranus, and Neptune) have primary atmospheres that were captured from the solar nebula. Some of the important chemical cycles that presently operate in planetary atmospheres are illustrated. Thermochemistry controls the atmospheric composition on Venus and in the deep atmospheres of the gas giant planets. In contrast, photochemistry dominates atmospheric chemistry on Mars and in the upper atmospheres of the gas giants. Biochemistry is the key process on Earth, with photochemistry also playing an important role. Some speculations about atmospheric chemistry and composition on extrasolar Earth-like planets are also presented.
Protective properties of GLP‐1 and associated peptide hormones in neurodegenerative disorders

Type 2 diabetes mellitus and the associated desensitisation of insulin signalling has been identified as a risk factor for progressive neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease and others. Glucagon‐like peptide 1 (GLP‐1) is a hormone that has growth factor‐like and neuroprotective properties. Several clinical trials have been conducted, testing GLP‐1 receptor agonists in patients with Alzheimer's disease, Parkinson's disease or diabetes‐induced memory impairments. The trials showed clear improvements in Alzheimer's disease, Parkinson's disease and diabetic patients. Glucose‐dependent insulinotropic polypeptide/gastric inhibitory peptide (GIP) is the ‘sister’ incretin hormone of GLP‐1. GIP analogues have shown neuroprotective effects in animal models of disease and can improve on the effects of GLP‐1. Novel dual GLP‐1/GIP receptor agonists have been developed that can enter the brain at an enhanced rate. The improved neuroprotective effects of these drugs suggest that they are superior to single GLP‐1 receptor agonists and could provide disease‐modifying care for Alzheimer's disease and Parkinson's disease patients.
A comparative insight into the bioactivity of mono- and binuclear silver(I)-N-heterocyclic carbene complexes: synthesis, lipophilicity and substituent effect

Abstract Silver(I)-N-heterocyclic carbene (Ag(I)-NHC) complexes of mononuclear and binuclear species, synthesised by our group and others in recent years, offer a fascinating outlook on their bioactivity. These complexes advance a range of adaptable structural patterns, leading to intra-specific variation in anticancer and antimicrobial activities. This study therefore reviews the synthesis, structural analysis and bioactivity of Ag complexes derived from mononuclear-NHC complexes either with coordinating or non-coordinating anions and binuclear NHC complexes. Specifically, the effect of stability, chain lengths and lipophilicity on the biological activity of recently reported Ag(I)-NHC complexes is reviewed. These complexes can be further explored as novel antibacterial and anticancer drugs in the nearest future.
Impact of tissue heterogeneity correction on Gamma Knife stereotactic radiosurgery of acoustic neuromas

Purpose/objectives Treatment planning systems (TPS) for Gamma Knife stereotactic radiosurgery (GK-SRS) include TMR10 algorithms, which assumes tissue homogeneity equivalent to water, and collapsed-cone convolutional (CCC) algorithms, which accounts for tissue inhomogeneity. This study investigated dosimetric differences between TMR10 and CCC TPS for acoustic neuromas (ANs) treated with GK-SRS. Materials/methods A retrospective review of 56 AN treated with GK-SRS was performed. All patients underwent MRI and CT imaging during their initial treatment and were planned using TMR10. Each plan was recalculated with CCC using electron density extracted from CT. Parameters of interest included Dmax, Dmin, D50%, cochlea Dmax, mean cochlea dose, target size, and laterality (>20 mm from central axis). Results Median target volume of patients was 1.5 cc (0.3 cc-2.8 cc) with median dose of 12 Gy prescribed to the 50% isodose line. Compared to CCC algorithms, the TMR10 calculated dose was higher: Dmax was higher by an average 6.2% (p < 0.001), Dmin was higher by an average 3.1% (p < 0.032), D50% was higher by an average of 11.3%. For lateralized targets, calculated Dmax and D50% were higher by 7.1% (p < 0.001) and 10.6% (p < 0.001), respectively. For targets <1 cc, Dmax and D50% were higher by 8.9% (p ≤ 0.009) and 12.1% (p ≤ 0.001), respectively. Cochlea Dmax was higher, by an average of 20.1% (p < 0.001). Conclusion There was a statistically significant dosimetric differences observed between TMR10 and CCC algorithms for AN GK-SRS, particularly in small and lateralized ANs. It may be important to note these differences when relating GK-SRS with standard heterogeneity-corrected SRS regimens.
Definite and indeterminate nonalcoholic steatohepatitis share similar clinical features and prognosis: A longitudinal study of 1893 biopsy‐proven nonalcoholic fatty liver disease subjects

Histological score systems may not fully capture the essential nonalcoholic steatohepatitis (NASH) features, which is one of the leading causes of screening failure in clinical trials. We assessed the NASH distribution and its components across the fibrosis stages and their impact on the prognosis and their relationship with the concept of metabolic‐associated fatty liver disease (MAFLD).
Use of omic technologies in early life gastrointestinal health and disease: from bench to bedside

ABSTRACT Introduction: At birth, the gastrointestinal (GI) tract is colonized by a complex community of microorganisms, forming the basis of the gut microbiome. The gut microbiome plays a fundamental role in host health, disorders of which can lead to an array of GI diseases, both short and long term. Pediatric GI diseases are responsible for significant morbidity and mortality, but many remain poorly understood. Recent advancements in high-throughput technologies have enabled deeper profiling of GI morbidities. Technologies, such as metagenomics, transcriptomics, proteomics and metabolomics, have already been used to identify associations with specific pathologies, and highlight an exciting area of research. However, since these diseases are often complex and multifactorial by nature, reliance on a single experimental approach may not capture the true biological complexity. Therefore, multi-omics aims to integrate singular omic data to further enhance our understanding of disease. Areas covered: This review will discuss and provide an overview of the main omic technologies that are used to study complex GI pathologies in early life. Expert opinion: Multi-omic technologies can help to unravel the complexities of several diseases during early life, aiding in biomarker discovery and enabling the development of novel therapeutics and augment predictive models.
The global challenge of hidden hunger: perspectives from the field

The aim of this review paper is to explore the strategies employed to tackle micronutrient deficiencies with illustrations from field-based experience. Hidden hunger is the presence of multiple micronutrient deficiencies (particularly iron, zinc, iodine and vitamin A), which can occur without a deficit in energy intake as a result of consuming an energy-dense, but nutrient-poor diet. It is estimated that it affects more than two billion people worldwide, particularly in low- and middle-income countries where there is a reliance on low-cost food staples and where the diversity of the diet is limited. Finding a way to improve the nutritional quality of diets for the poorest people is central to meeting the UN sustainable development goals particularly sustainable development goal 2: end hunger, achieve food security and improved nutrition and promote sustainable agriculture. As we pass the midpoint of the UN's Decade for Action on Nutrition, it is timely to reflect on progress towards achieving sustainable development goal 2 and the strategies to reduce hidden hunger. Many low- and middle-income countries are falling behind national nutrition targets, and this has been exacerbated by the COVID-19 pandemic as well as other recent shocks to the global food system which have disproportionately impacted the world's most vulnerable communities. Addressing inequalities within the food system must be central to developing a sustainable, cost-effective strategy for improving food quality that delivers benefit to the seldom heard and marginalised communities.
Montage-related Variability in the Characteristics of Envelope Following Responses

Objectives: The study aimed to compare two electrode montages commonly used for recording speech-evoked envelope following responses. Design: Twenty-three normal-hearing adults participated in this study. EFRs were elicited by a naturally spoken, modified /susa∫i/ stimulus presented at 65 dB SPL monaurally. EFRs were recorded using two single-channel electrode montages: Cz-nape and Fz-ipsilateral mastoid, where the noninverting and inverting sites were the vertex and nape, and the high forehead and ipsilateral mastoid, respectively. Montage order was counterbalanced across participants. Results: Envelope following responses amplitude and phase coherence were significantly higher overall in the Cz-nape montage with no significant differences in noise amplitude. Post hoc testing on montage effects in response amplitude and phase coherence was not significant for individual stimuli. The Cz-nape montage also resulted in a greater number of detections and analyzed using the Hotelling’s T2. Conclusions: Electrode montage influences the estimated characteristics of speech-evoked EFRs.
Mechanical properties and surface roughness of chitosan reinforced heat polymerized denture base resin.

PURPOSE The antifungal property of chitosan (Ch) in denture base resin (DBR) was well established. Ch influence on the mechanical properties of DBR is less studied in the literature and is vital for clinical success of denture. This study estimates the effect of different concentrations of Ch on the flexural strength (FS), fracture toughness (FT), impact strength (IS) and surface roughness (Ra) in heat polymerized DBR. METHODS A total of 160 samples were divided into 4 groups (n =10) by weight percentage - Ch 0, Ch 5, Ch 10, Ch 15. FS and FT were estimated by three-point bending test. IS was determined by Charpy test. Ra was evaluated by non-contact laser surface profilometer. The tested samples were characterized by scanning electron microscope and Fourier transformation infra-red spectroscopy. Data were statistical analyzed with one-way ANOVA and Post hoc Bonferroni test. RESULTS FS, FT and IS improved with Ch addition when compared to control group. Ch5 showed higher "FS, FT, IS. (p<0.001)". Increased Ra was observed in Ch5 and Ch10 with significant statistical differences among the g roups. (p <0.001) Ch15 displayed decrease in Ra compared to control group. CONCLUSIONS The addition of Ch to DBR improved the "FS, FT, IS at 5%wt and Ra at 15%wt" of Ch.
Daytime and nighttime smartphone use: A study of associations between multidimensional smartphone behaviours and sleep among 24,856 Danish adults

The around‐the‐clock smartphone use and its relation to disturbed sleep is a public health concern. The present study aimed to quantify the effects of different dimensions of smartphone behaviours (frequency of daytime use, problematic use, use before sleep and use during the sleep period) on disturbed sleep (sleep quality and sleep quantity) and to disentangle their inter‐relationship in a large population‐based sample of 24,856 Danish adults aged ≥16 years. Data come from the SmartSleep Experiment, which is a web‐based survey carried out using a citizen science approach. Tested items were used to evaluate smartphone use and disturbed sleep was evaluated with the Karolinska Sleep Questionnaire (KSQ). Linear and multinomial logistic regression was employed to evaluate the relationship between smartphone use and disturbed sleep. While several of the smartphone measures were associated with disturbed sleep when assessed individually, smartphone use during the sleep period was the only dimension consistently associated with disturbed sleep when assessed independently of other smartphone behaviours. Weekly smartphone use during the sleep period versus no use was associated on average with a 0.96 point higher score (95% confidence interval [CI] 0.90–1.02) on the 5‐point KSQ scale, and a higher risk of both short (odds ratio [OR] 1.32, 95% CI 1.08–1.62) and long (OR 1.94, 95% CI 1.63–2.32) sleep duration. Smartphone use during the sleep period is the factor strongest associated to disturbed sleep relative to other dimensions of smartphone use. Recommendations around smartphone use during the sleep period are warranted in order to protect the fundamentally important biological and mental processes of sleep.
The First Fatal Post-COVID-19 Adult Patient with Multi-System Inflammatory Syndrome in Israel.

BACKGROUND Coronavirus disease-2019 (COVID-19) is recognized as a respiratory illness, which includes pulmonary consolidations, hypoxemic states, and hypercoagulopathic tendencies with a broad clinical severity. Recently, more reports have described post-infection manifestations. These include multi-system inflammatory syndrome in children (MIS-C) with more than 400 cases published since the start of the coronavirus disease pandemic. In October 2020, the U.S. Centers for Disease Control and Prevention (CDC) published 27 cases [1] describing the new multi-system inflammatory syndrome in adults (MIS-A). Nine of the cases were reported directly to the CDC, 7 from published case reports and another 11 patients found in three distinct case series.
Maternal lack of sleep in the first two years after childbirth: Perceived impacts and help-seeking behaviors.

Most evidence-based sleep interventions (e.g., graduated extinction of nighttime crying) are in opposition to many parents' values. This warrants taking a step back and asking the parents about their main concerns regarding their baby's sleep and the type of help they would be likely to use. This study aimed to describe and identify, among mothers of a 0- to 24-month-old child, the perceived impact of lack of sleep, sleep-related help-seeking behaviors as well as the most concerning aspects of the child's sleep, and preferred sleep intervention modalities. Another objective was to identify the factors associated with a negative impact of postpartum sleep, concerns for the child's sleep, and interest in sleep interventions. Canadian mothers (N = 932) were recruited by email snowball sampling and through Facebook to complete an online questionnaire designed for the purposes of the study. Most mothers reported a negative impact of postpartum sleep on their romantic relationship (79.4%) and quality of life (76.7%). Low parental self-efficacy (PSE) about managing the child's sleep was the best predictor of a negative impact of lack of sleep and sleep-related concerns, above and beyond any other child's or mother's characteristics. The preferred intervention modalities were reliable websites and online courses on child sleep, with a greater interest in home visits among mothers who need help the most (low self-efficacy, high concerns). Interventions should aim at increasing PSE about the child's sleep in both parents and include home visits for those who need it the most.
The “Double Burden of Malnutrition” in the Amazon: dietary change and drastic increases in obesity and anemia over 40 years among the Awajún

ABSTRACT Undernutrition and overnutrition are interconnected. Yet few studies have examined the “double burden of malnutrition” (DBM) over time in indigenous communities. We investigated changes in the food systems and nutritional health of Awajún communities in the Peruvian Amazon in the 1970s and in 2013. Methods included ethnography, 24 hr food recalls, and biological measures. In 2013, the number of traditional foods consumed decreased to 10% of levels in the 1970s and the number of market foods consumed increased 40-fold. Rates of anemia and obesity were also substantially higher in 2013 compared to the 1970s (23% vs 6% for anemia and 30% vs. 0% for obesity) indicating a DBM has emerged. Examining the predictors of hemoglobin levels and body mass indices in the 2013 sample reveals that this DBM is differentially impacting women and that risk for obesity among the Awajún is associated with multiple proxies of market integration beyond just the consumption of market foods. These findings highlight the complex pathways by which rapid lifestyle changes are creating gendered health inequalities within indigenous communities over time.
Clinicopathological correlation of stem cell markers expression in oral squamous cell carcinoma; relation to patients` outcome

ABSTRACT Background: Squamous cell carcinoma (OSCC) is the commonest oral malignancy.The overall 5 year survival of OSCC has remained at 50%, largely unchanged for 40 years. CSCs are important within the development, invasion, drug resistance, and prediction of carcinomas treatment outcome. ALDH1 and CD44 are commonly used epithelial tumors cancer stem-like cells surface markers. Materials: Our study aimed to judge CD44 and ALDH1 immunohistochemical expressions in 44 cases of OSCC and relates the expression to patients’ survival. Results: High CD44 & ALDH1 expressions were significantly expressed in variable histologic grades of OSCCs, large sized carcinomas, presence lymph vascular invasion, presence of nodal and distant metastasis, advanced TNM clinical stage, recurrence and death during follow up period (P ≤ 0.05). Reduced DFS and three years overall survival were significantly recorded in cases with high CD44 expression, and high ALDH1 expression (p < 0.05). CD44 & ALDH1 expressions, histologic grade, tumor size were the independent predictors of DFS and three years OS. Conclusion: CD44 and ALDH1 expressions are valuable prognostic factors in OSCC and could be well considered predictors for patients’ 3 years OS and DFS.
Sleep deprivation reduces vagal tone during an inspiratory endurance task in humans.

STUDY OBJECTIVES Sleep deprivation alters inspiratory endurance by reducing inspiratory motor output. Vagal tone is involved in exercise endurance. This study aimed to investigate the effect of sleep deprivation on vagal tone adaptation in healthy subjects performing an inspiratory effort. METHODS Vagal tone was assessed using Heart Rate Variability normalized units of frequency domain component HF (high frequency) before, at the start, and the end of an inspiratory loading trial performed until exhaustion by 16 volunteers after one night of sleep deprivation and one night of normal sleep, where sleep deprivation reduced the inspiratory endurance by half compared to the normal sleep condition (30min vs 60 min). RESULTS At rest, heart rate was similar in sleep deprivation and normal sleep conditions. In normal sleep condition, heart rate increased during inspiratory loading task; this increase was greater in sleep deprivation condition. In normal sleep condition, vagal tone increased at the beginning of the trial. This vagal tone increase was absent in sleep deprivation condition. CONCLUSIONS Sleep deprivation abolished vagal tone response to inspiratory load, possibly contributing to a higher heart rate during the trial and to a reduced inspiratory endurance.
Listeria monocytogenes: review of pathogenesis and virulence determinants-targeted immunological assays

Abstract Listeria monocytogenes is one of the most invasive foodborne pathogens and is responsible for numerous outbreaks worldwide. Most of the methods to detect this bacterium in food require selective enrichment using traditional bacterial culture techniques that can be time-consuming and labour-intensive. Moreover, molecular methods are expensive and need specific technical knowledge. In contrast, immunological approaches are faster, simpler, and user-friendly alternatives and have been developed for the detection of L. monocytogenes in food, environmental, and clinical samples. These techniques are dependent on the constitutive expression of L. monocytogenes antigens and the specificity of the antibodies used. Here, updated knowledge on pathogenesis and the key immunogenic virulence determinants of L. monocytogenes that are used for the generation of monoclonal and polyclonal antibodies for the serological assay development are summarised. In addition, immunological approaches based on enzyme-linked immunosorbent assay, immunofluorescence, lateral flow immunochromatographic assays, and immunosensors with relevant improvements are highlighted. Though the sensitivity and specificity of the assays were improved significantly, methods still face many challenges that require further validation before use.
Prevalence, sociodemographic variables, mental health condition, and type of drug use associated with suicide behaviors among people with substance use disorders: a systematic review and meta-analysis

Abstract We assessed the prevalence, sociodemographic variables, mental health condition, and type of drug use associated with suicide behaviors among patients with substance use disorders (SUD). Studies in English published from January 1, 1995 to December 31, 2020 were searched on PubMed, Scopus, Cochrane and Web of Science to identify studies on variables associated with suicidal behaviors (ideations and attempts) among patients with SUD. After reviewing for study duplicates, the full-text of selected articles were assessed for eligibility using Population, Intervention, Comparator, Outcomes (PICO) criteria: (i) population: patients with SUD; (ii) intervention: suicide behaviors in the past year; (iii) comparator: SUD who had not suicide behaviors; (iv) outcome: suicide ideations or attempts in the last year; and (v) study type: cross-sectional, cohort, and case–control studies. Out of 10,810 articles, 48 studies met eligibility criteria. Our findings showed a pooled prevalence rate of suicide ideations of 35% (95% CI, 22% 48%) and suicide attempts of 20% (95% CI, 17% 23%) in the last year among patients with SUD. Smoking, previous history of sexual abuse, depression, and alcohol and cannabis use disorders were significantly associated with suicide ideations. Study findings also showed that being female, smoking, history of physical and sexual abuse, depression and alcohol, cannabis, cocaine, amphetamine use disorders, and polysubstance abuse were significantly associated with suicide attempts among patients with SUD. These findings have implications for developing prevention programs. Appropriate initiatives for reducing the risk of suicide behaviors like systematic assessments of changes in drug use pattern at the emergency departments or at other key health providers may be more broadly implemented. Motivational therapy to improve help-seeking, increased information on adverse consequences of heavy substance use, and crisis plan resolutions to face suicide behaviors could also be consolidated.
