Potential of the Red Macroalga Bonnemaisonia hamifera in Reducing Methane Emissions from Ruminants

Simple Summary Methane is a gas that ruminants naturally release during digestion, and it is a significant contributor to global warming. In efforts to reduce the environmental impact of livestock farming, we explored a red macroalga called Bonnemaisonia hamifera. This macroalga was collected from the shores of Sweden and used in an in vitro digestion experiment to evaluate its effects on ruminal fermentation and methane production from dairy cows. The study examined different inclusion levels of the macroalga in grass silage. We noticed an increase in the proportion of propionate in rumen fluid and a reduction in methane production with inclusion of the macroalga. This is important because reducing methane emissions from ruminants would be beneficial for the environment. B. hamifera exhibited antioxidant properties, which could be beneficial for the animals. In conclusion, this study shows that B. hamifera from Sweden has the potential to make livestock farming more eco-friendly by decreasing methane gas emissions. Abstract Researchers have been exploring seaweeds to reduce methane (CH4) emissions from livestock. This study aimed to investigate the potential of a red macroalga, B. hamifera, as an alternative to mitigate CH4 emissions. B. hamifera, harvested from the west coast of Sweden, was used in an in vitro experiment using a fully automated gas production system. The experiment was a randomized complete block design consisting of a 48 h incubation that included a control (grass silage) and B. hamifera inclusions at 2.5%, 5.0%, and 7.5% of grass silage OM mixed with buffered rumen fluid. Predicted in vivo CH4 production and total gas production were estimated by applying a set of models to the gas production data and in vitro fermentation characteristics were evaluated. The results demonstrated that the inclusion of B. hamifera reduced (p = 0.01) predicted in vivo CH4 and total gas productions, and total gas production linearly decreased (p = 0.03) with inclusion of B. hamifera. The molar proportion of propionate increased (p = 0.03) while isovalerate decreased (p = 0.04) with inclusion of B. hamifera. Chemical analyses revealed that B. hamifera had moderate concentrations of polyphenols. The iodine content was low, and there was no detectable bromoform, suggesting quality advantages over Asparagopsis taxiformis. Additionally, B. hamifera exhibited antioxidant activity similar to Resveratrol. The findings of this study indicated that B. hamifera harvested from temperate waters of Sweden possesses capacity to mitigate CH4 in vitro.
Rates of Preterm Birth and Low Birth Weight in an Adolescent Obstetric Clinic: Achieving Health Equity Through Trauma-Informed Care

Objectives: Adolescents who are pregnant and identify as Black are exposed to more societal harms that increase their and their offspring's risk for poor health outcomes. The Colorado Adolescent Maternity Program (CAMP) offers comprehensive, multidisciplinary (medical, behavioral health, nutrition, case management), trauma-informed obstetric care to pregnant adolescents to ensure the healthiest pregnancy and birth possible and pursue health equity. The present study aimed to examine ethnic and racial disparities in preterm birth and low birth weight before and after implementation of a trauma-informed model of care. Methods: Participants were 847 pregnant adolescents (ages 12–22 years; 41% self-identified as Hispanic, 32% as non-Hispanic Black, 21% as non-Hispanic white) who received prenatal treatment-as-usual (TAU) or trauma-informed treatment. Demographic information, mental health symptoms, and birth outcomes were abstracted from medical records. Results: Overall, findings provided support that implementation of a trauma-informed model of prenatal care led to equitable birth outcomes across racial and ethnic groups. Specifically, Black adolescents in the TAU group were more than twice as likely to deliver preterm or low birth weight infants compared with white and Hispanic adolescents. In the trauma-informed group, however, there were no statistical differences in birth outcomes across racial/ethnic groups, indicating an elimination of disparities in both preterm birth and low birth weight in this population. These more equitable birth outcomes occurred even in the context of adolescents of color having reported more severe depression symptoms postimplementation. Conclusions: These findings provide evidence that a health system-level intervention, herein trauma-informed obstetric care for adolescents, can play a meaningful role in the reduction of racial disparities in birth outcomes.
Patients’ perspectives on marijuana use for inflammatory bowel disease: a multicenter survey

Background As marijuana use is rising among patients with inflammatory bowel disease (IBD), so is interest in its potential use as a therapeutic agent. We sought to survey IBD patients regarding marijuana use, self-reported impact on IBD symptoms, and perceptions of safety. Methods A multicenter anonymous survey was administered to patients with IBD between October 2020 and June 2021. The 70-question survey collected demographic variables, clinical variables, attitudes about marijuana, and perceptions of its safety and efficacy in IBD. Participants were classified by their marijuana use: “rarely/never,” “current,” and “former”. Percentage and chi-square tests were used to compare categorical variables between the 3 groups, and means and 2-group ANOVA were used for continuous variables. Results Of 181 patients surveyed, 166 were eligible for the study. Of these, 70 (42.2%) participants were rare/never marijuana users, 44 (26.5%) were current users, and 52 (31.3%) were former users. Fifty-three percent thought marijuana would help with IBD inflammation and 80% thought it would help with IBD pain. Over 70% of patients from all groups thought marijuana had a low-to-moderate risk of harm, and 69.6% of the participants who never or rarely used marijuana thought marijuana was addictive, compared to 20.5% of the current users and 44% of the former marijuana users. Conclusions While many patients thought marijuana use helps with IBD-related pain and inflammation, many expressed concerns about addiction to marijuana and a possible risk of harm. Further studies are needed to examine the benefit and harm of marijuana in IBD.
A Novel Detection and Localization Scheme for Wormhole Attack in Internet of Things

With the explosive growth of Internet of Things (IoT) devices, the IPv6 routing protocol for low-power and lossy networks (RPL) has been widely studied and applied. However, due to lack of complete security mechanisms, it faces many threats, one of which is wormhole attack. Wormhole attack could mislead network traffic flow, cause network congestion and increase packet delivery latency. Besides, it can also be combined with the other types of attacks to become more threatening. In this article, we propose two schemes, called routing loop detection for wormhole and routing loop detection for wormhole combined with greyhole, to detect wormhole nodes for different attack modes in RPL-based networks. Our methods could not only detect but also localize the adversaries more effectively in comparison with the state-of-the-art scheme, LiDL. We have completely implemented the proposed two schemes, as well as LiDL, in the Contiki IoT operating system and made an extensive comparison among them based on the Sky mote. The obtained results demonstrate the feasibility and superiority of our schemes in terms of detection speed, accuracy and network performance improvement.
Performance of summer sesame (Sesamum indicum L.) and estimation of economic and optimum doses of nitrogen and phosphorus in red and laterite soils of West Bengal.

A field experiment was conducted at the Regional Research Substation, Sekhampur, Birbhum, Bidhan Chandra Krishi Viswavidyalaya, West Bengal during early summer of 2009 and 2010 to study the performance of sesamum grown with variable rates of N and P levels and to compute the optimum and economic levels of the applied nutrients. The treatments comprised of four levels each of N (0, 20, 40 and 80 kg ha) and P (0,10,20 and 40 kg ha) laid out in a factorial randomized complete block design with three replications. Increasing the application rates of N and P enhanced the number of seeds/capsule, number of capsules/plant and thousand grains weight. The highest average mean seed yields were obtained with 80 kg haN (953 kg ha) and 40 kg haP (857 kg ha). The agronomic efficiencies were highest with lower application rates of N (16.3 kg kg of N) and P (22.6 kg kg of P). The relationship between the applied amounts of N and P with sesamum yield was defined by quadratic functions. The estimated optimum levels of N and P were 72 and 36 kg hawhile the economic levels were 61 and 35 kg harespectively.
Fluidic Simulation and Optimization of Microchannels for Retinal Vein Occlusion (RVO) by Using Fuzzy Technique

A microelectromechanical system (MEMS) is a diminutive machine having electronic and mechanical components with a size ranging from 20 µm-1 mm. In this present-day world, MEMS fabrication techniques have remodeled the conventional approaches towards system fabrication. Microfluidics is an eminent domain of MEMS in which small volumes of fluids are disciplined in micro-channels having dimensions in the submillimeter to achieve the desired outputs. Microfluidics have revolutionized the realm of compact system fabrication through preeminent inventions like lab-on-a-chip technology. Microchannels of various architectures are fabricated to employ microfluidic systems depending upon the required function of the device. In ophthalmology, Retinal Vein Occlusion (RVO) is an ailment in which small veins that take away blood from the human eye's retina are blocked or fissured, causing vision loss. Therefore, in this study, four micro-channels with different architectures, namely, sinusoidal, U-shaped, spiral, and curvilinear, were simulated by using the fuzzy technique to investigate the optimization of fluids for the implantation process to fix the RVO elixir. The two most critical parameters in retinal vein flow rate and velocity were taken at the output for optimization. Hence, fuzzy fluidic simulation revealed that curvilinear micro-channels were the best fit for biomedical implantation to treat RVO malady.
California Undersea Aqueduct Reconnaissance: the Oceanography (CUARO)

Abstract : The report discusses the possibility of conveying fresh water from northern to southern California via a subsurface offshore aqueduct (the California Undersea Aqueduct). The specific region investigated was between Crescent City and San Diego from the 20- to 200-m depth contour. All available data on relevant variables were analyzed to provide information for aqueduct planning decisions. The variables and analyses most influential in planning the California Undersea Aqueduct were divided into two categories: variables influencing the 100-year survival of the aqueduct(century risks) and variables influencing the construction and maintenance of the aqueduct. Waves, surges, tsunamis, density, and light do not appear on the basis of reconnaissance data to pose insurmountable problems. Surface, water column, and bottom currents, including upwelling and internal wave phenomena, may or may not be prohibitive; data are inadequate, and additional information must be obtained from in situ observations. Canyons are not an insurmountable threat, but will pose innovative engineering challenges and probably be quite expensive. Additional data will also be required on these processes.
Is there a direct relationship between hiatal hernia size, esophageal body hypomotility and symptomatic perception of gastroesophageal reflux episodes?

Background The esophagogastric junction (EGJ) is classified into 3 anatomical subtypes according to lower esophageal sphincter-crural diaphragm (LES-CD) separation. We aimed to assess their relationship to esophageal motility, reflux characteristics, and symptom perception. Methods We analyzed data from 1740 consecutive patients with typical reflux symptoms, who underwent high resolution manometry and a 24-h pH-impedance study during a 13-year period. A diagnosis of gastroesophageal reflux disease (GERD) was made if acid exposure time (AET) was >6%. EGJ types were classified as 1, 2, or 3, if LES-CD separation was up to 1 cm, 1-3 cm, or ≥3 cm, respectively. Results EGJ type distribution was 72.2%, 22.1% and 5.7%, for types 1, 2 and 3, respectively. GERD was diagnosed in 31.2% and was more common among patients with EGJ type 2/3 vs. 1 (P<0.001). Length of LES-CD separation significantly correlated with AET and number of reflux episodes. Patients with type 2 or 3 EGJ more often showed ineffective or absent peristalsis compared with type 1 (P=0.008 and P<0.001 respectively). In the multivariate analysis, EGJ type 2/3 correlated with AET (P=0.001) and reflux episodes (P=0.041) but not with positive symptomatic markers or with ineffective/absent peristalsis. Conclusions Our study confirms that EGJ anatomical morphology is a strong risk factor for GERD and correlates with both AET and the number of reflux events, though the length of separation is more important than the type. The multivariate analysis revealed that EGJ type 2 or 3 was not correlated with symptom perception or esophageal hypomotility.
Les isotopes stables à l'eau : applications à l'étude du cycle de l'eau et des variations du climat

Les isotopes stables de l'eau (H216O, HDO, H218O , H2O17) sont de plus en plus utilises pour etudier le cycle de l'eau actuel et ses variations passees. Le but de cette these est de mieux comprendre les processus affectant la composition isotopique de l'eau (precipitation, eau atmospherique et des reservoirs continentaux). En retour, que peut apporter la composition isotopique sur la convection atmospherique et l'hydrologie de surface? Peut-elle aider a mieux contraindre leur representation dans les modeles? Quelles informations apportent les archives isotopiques sur les variations passees du climat? Nous tentons de repondre a ces questions en utilisant differents types de modeles (modele uni-colonne d'atmosphere tropicale, modele 2D de ligne de grains, modele de circulation generale LMDZ, modele d'hydrologie continentale ORCHIDEE) dans lesquels nous avons introduit les isotopes stables de l'eau, et des donnees isotopiques de pluies collectees au Niger pendant campagne de terrain AMMA.

Functional and structural connectivity success predictors of real-time fMRI neurofeedback targeting DLPFC: Contributions from central executive, salience, and default mode networks

Abstract Real-time functional magnetic resonance imaging (rt-fMRI) neurofeedback (NF), a training method for the self-regulation of brain activity, has shown promising results as a neurorehabilitation tool, depending on the ability of the patient to succeed in neuromodulation. This study explores connectivity-based structural and functional success predictors in an NF n-back working memory paradigm targeting the dorsolateral prefrontal cortex (DLPFC). We established as the NF success metric the linear trend on the ability to modulate the target region during NF runs and performed a linear regression model considering structural and functional connectivity (intrinsic and seed-based) metrics. We found a positive correlation between NF success and the default mode network (DMN) intrinsic functional connectivity and a negative correlation with the DLPFC-precuneus connectivity during the 2-back condition, indicating that success is associated with larger uncoupling between DMN and the executive network. Regarding structural connectivity, the salience network emerges as the main contributor to success. Both functional and structural classification models showed good performance with 77% and 86% accuracy, respectively. Dynamic switching between DMN, salience network and central executive network seems to be the key for neurofeedback success, independently indicated by functional connectivity on the localizer run and structural connectivity data.
Mechanisms of PIEZO Channel Inactivation

PIEZO channels PIEZO1 and PIEZO2 are the newly identified mechanosensitive, non-selective cation channels permeable to Ca2+. In higher vertebrates, PIEZO1 is expressed ubiquitously in most tissues and cells while PIEZO2 is expressed more specifically in the peripheral sensory neurons. PIEZO channels contribute to a wide range of biological behaviors and developmental processes, therefore driving significant attention in the effort to understand their molecular properties. One prominent property of PIEZO channels is their rapid inactivation, which manifests itself as a decrease in channel open probability in the presence of a sustained mechanical stimulus. The lack of the PIEZO channel inactivation is linked to various mechanopathologies emphasizing the significance of studying this PIEZO channel property and the factors affecting it. In the present review, we discuss the mechanisms underlying the PIEZO channel inactivation, its modulation by the interaction of the channels with lipids and/or proteins, and how the changes in PIEZO inactivation by the channel mutations can cause a variety of diseases in animals and humans.
