Growth, reproduction and recruitment of Eisenia andrei in natural substrates: A functional approach

En esta tesis se realiza un estudio de la respuesta fisiologica de individuos de la especie de lombriz epigea Eisenia andrei sometidos a distintas condiciones de cultivo en substratos naturales. Uno de los parametros a evaluar es el efecto del aislamiento y densidad poblacional sobre el crecimiento y metabolismo aerobio. Para ello se establecio un sistema de mesocosmos, usando como substrato bosta de caballo, en donde los individuos fueron marcados con elastomeros fluorescentes para poder realizar un seguimiento individualizado, y se realizo un estudio comparativo con animales cultivados de forma aislada. Como resultado, los individuos aislados mostraban mayores tasas de crecimiento y metabolicas, que son explicadas por una menor inversion en reproduccion y por la mayor cantidad de comida por individuo. Por otra parte, se evaluo el efecto de la dieta, en terminos de cantidad y calidad de la materia organica, sobre los parametros del ciclo vital de Eisenia andrei. En este caso, los substratos utilizados fueron hierba cortada y compostada por distintos periodos de tiempo y suelo perteneciente a tres tipos de unidades de vegetacion (Plantacion de Eucalipto, Robledal y Matorral-Espinar). Como resultado, la idoneidad de estos substratos para mantener poblaciones activas de E. andrei parece estar relacionado con la cantidad de materia organica facilmente digerible (p. ej. Proporcion de carbohidratos solubles). Por ultimo mencionar que en esta tesis se ha desarrollado un sistema no invasivo de toma de datos morfometricos y de biomasa basado en tecnicas fotograficas.
GEOMETRIC NONLINEAR DYNAMICAL CONTROL

This paper presents a brief introduction to the controllability of nonlinear systems through geometrical techniques. More specifically, Lie brackets are used to steer the system in directions not initially apparent from the linearization of the system. This allows us to prove an analogous result to the rank Kalman condition for controllability of nonlinear systems known as the accessibility rank condition.
What it means to be a woman in the field of biomedical informatics: exploring the lived experiences of women managers in the kingdom of Saudi Arabia

OBJECTIVE Although women in the field of biomedical informatics (BMI) are part of a golden era, little is known about their lived experiences as informaticians. Guided by feminist standpoint theory, this study aims to understand the impact of social change in the Kingdom of Saudi Arabia- in the form of new policies supporting women and health technological advancements-in the field of BMI and its women informaticians. MATERIALS AND METHODS We conducted semistructured telephone interviews with 7 women managers in the field of BMI, identified through LinkedIn. We analyzed interview transcripts to generate themes about their lived experiences, how they perceived health information technology tools, identified challenges that may hinder the advancement of the field, and explored the future of BMI from their perspectives. During our analysis, we utilized a feminist theoretical approach. RESULTS Women managers in the field of BMI shared similar experiences and perspectives. Our analysis generated 10 themes: (1) career beginning, (2) opportunities given, (3) career achievements, (4) gender-based experiences, (5) meaning of BMI, (6) meaning of health information technology tools, (7) challenges, (8) overcoming challenges, (9) future and hopes, and (10) meaning of "2030 Saudi vision. " Early in their careers, participants experienced limited opportunities and misperceptions in understanding what the field of informatics represents. Participants did not feel that gender was an issue, despite what feminist theory would have predicted. CONCLUSIONS Recognizing the lived experiences of women in the field of BMI contributes to our collective understanding of how these experiences may enhance our knowledge of the field.
Commentary: Robotic Techniques in Cardiac and Thoracic Surgery (Innovations, May/June 2020)

This is a response to the papers in the May/June issue of Innovations focused on robotic techniques in cardiac and thoracic surgery. Successful robotic surgery relies on a high level of preparation and communication from each member of the operating room. The lack of a team approach can result in not only failure to establish and/or sustain a robotic program, but more importantly, in serious consequences at the detriment to patient care and safety. While these are salient points, the authors of this commentary wish to highlight that the first robot-assisted mitral valve surgery in North America was performed at NYU Langone Health using the Zeus robotic surgical system. Although that robotic platform had several disadvantages that limited its clinical advancement, an appreciation for this history in robotic cardiac surgery is important if we as cardiothoracic surgeons seek to move toward a future of expanding robotic surgery within the ever-changing landscape of cardiac surgery.
A TIME FRACTIONAL FUNCTIONAL DIFFERENTIAL EQUATION DRIVEN BY THE FRACTIONAL BROWNIAN MOTION

for all t, s ≥ 0. When H = 1/2, B coincides with the standard Brownian motion B. B is neither a semimartingale nor a Markov process unless H = 1/2, so many of the powerful techniques from stochastic analysis are not available when dealing with B . As a Gaussian process, one can construct the stochastic calculus of variations with respect to B . Some surveys and complete literatures for fractional Brownian motion could be found in Biagini et al [3], Hu [9], Mandelbrot and Ness [11], Mishura [12], Nourdin [13], Nualart [15] and the references therein. On the other hand, differential equation with fractional derivative can be used to describe the hereditary character of various kinds of materials and processes. Compare to the classical differential equation, the fractional order models are better to fit the models of the real life. The advantages of fractional derivatives become apparent in various fields of science and engineering such as control theory, porous
Longitudinal evaluation of perceived stress and memory complaints in the Einstein Aging Study

ABSTRACT Background Perceived stress decreases memory performance and escalates the risk of developing cognitive impairment. Despite these concerning cognitive outcomes, longitudinal assessment of the relationship between perceived stress and memory complaints within a racially diverse sample remains scant. Method 391 cognitively intact older adults (M = 77.31, SD = 4.75) from the Einstein Aging Study were measured annually for up to nine years. Memory complaint items included self-reported frequency of forgetfulness, one-year memory decline, and 10-year memory decline. Multilevel models examined between-person and within-person associations between perceived stress and memory complaints while controlling for demographic differences and neuroticism. Results Strong between-person associations emerged such that older adults with generally higher perceived stress were more likely to report memory complaints, and vice versa. No significant concurrent within-person associations emerged. One lagged association emerged showing that within-person increases in perceived stress translated to a higher likelihood of reporting 10-year memory decline at the next annual screening. Conclusion Older adults with higher perceived stress are at risk for memory complaints over time. Further research into the relationship between perceived stress and memory complaints is necessary to augment our understanding of how risk factors of cognitive decline present throughout the aging process.

Daily Distance Traveled Is Associated with Greater Brain Size in Primates

Explanations for the brain size increments through primate and, particularly, human evolution are numerous. Commonly, these hypotheses rely on the influence that behavioral and ecological variables have on brain size in extant primates, such as diet quality, social group size, or home range (HR) area. However, HR area does not reflect the time spent moving. As such, it has not been properly addressed whether the effort involved in movement could have affected brain size evolution in primates. This study aimed to test the influence of daily movement on primates’ brain sizes, controlling for these other behavioral and ecological factors. We used a large comparative dataset of extant primate species and phylogenetic comparative methods. Our results show a significant correlation between daily movement and brain mass, which is not explained by the influence of diet, social group size, HR, or body mass. Hence, from an evolutionary timescale, a longer daily movement distance is not a constraining factor for the energetic investment in a larger brain. On the contrary, increased mobility could have contributed to brain mass incrementations through evolution.
AMP-activated protein kinase as a novel regulator of vascular tone

AMPK is a well-known metabolic key enzyme but its role in the regulation of vascular tone is largely unknown. Here we identified AMPK as a potent vasodilator in small arteries acting mainly by two different mechanisms, namely by (1) lowering intracellular calcium through activation of potassium (BKCa) channels and SERCA and by (2) reducing the calcium sensitivity of smooth muscle due to actin depolymerization caused by activation of the actin severing protein cofilin.
Multimodal Data Fusion of Electromyography and Acoustic Signals for Thai Syllable Recognition

Speech disorders such as dysarthria are common and frequent after suffering a stroke. Speech rehabilitation performed by a speech-language pathologist is needed to improve and recover. However, in Thailand, there is a shortage of speech-language pathologists. In this paper, we present a syllable recognition system, which can be deployable in a speech rehabilitation system to provide support to the limited speech-language pathologists available. The proposed system is based on a multimodal fusion of acoustic signal and surface electromyography (sEMG) collected from facial muscles. Multimodal data fusion is studied to improve signal collection under noisy situations while reducing the number of electrodes needed. The signals are simultaneously collected while articulating 12 Thai syllables designed for rehabilitation exercises. Several features are extracted from sEMG signals and five channels are studied. The best combination of features and channels is chosen to be fused with the mel-frequency cepstral coefficients extracted from the acoustic signal. The feature vector from each signal source is projected by spectral regression extreme learning machine and concatenated. Data from seven healthy subjects were collected for evaluation purposes. Results show that the multimodal fusion outperforms the use of a single signal source achieving up to $\sim\! \text{98}\%$ of accuracy. In other words, an accuracy improvement up to $\text{5}\%$ can be achieved when using the proposed multimodal fusion. Moreover, its low standard deviations in classification accuracy compared to those from the unimodal fusion indicate the improvement in the robustness of the syllable recognition.
Diagnostic role of circulating MiR-21 in colorectal cancer: a update meta-analysis

Abstract Aim MicroRNA-21 is an oncogenic miRNA that modulates the expression of multiple cancer-related target genes. We conducted this meta-analysis to assess diagnostic role of circulating miR-21 in CRC, hoping to choose the best biomarker in CRC diagnosis. Methods We searched the PubMed, CNKI and WanFang database to identify records related to diagnostic role of circulating miR-21 in CRC. The search words were “microRNA-21”, “miRNA-21”, “colorectal cancer”, “colorectal carcinoma” and “diagnosis”. The searched articles were published before 14th July 2020. Results We got 18 studies to conduct this meta-analysis including 1129 blood specimens of CRC patients and 951 control specimens. The meta-analysis showed that the pooled sensitivity and specificity of circulating miR-21 for CRC diagnosis were 77% (95% CI, 70–82) and 83% (95% CI, 78–88). The combined positive likelihood ratio (PLR) was 4.20 (95% CI, 3.12–5.66) and the combined negative likelihood ratio(NLR) was 0.30 (95% CI, 0.23–0.38). The diagnostic odds ratio (DOR) was 16.48 (95% CI 10.09–26.91) and the area under the summary receiver operating characteristic curve (SROC) for the included studies was 0.87(95%CI, 0.84–0.90). Conclusion Our meta-analysis results suggest that circulating miR-21 has a potential diagnostic value with moderate sensitivity and good specificity for CRC.
Geometry and the Organizational Principle of Spine Synapses along a Dendrite

Abstract Precise information on synapse organization in a dendrite is crucial to understanding the mechanisms underlying voltage integration and the variability in the strength of synaptic inputs across dendrites of different complex morphologies. Here, we used focused ion beam/scanning electron microscope (FIB/SEM) to image the dendritic spines of mice in the hippocampal CA1 region, CA3 region, somatosensory cortex, striatum, and cerebellum (CB). Our results show that the spine geometry and dimensions differ across neuronal cell types. Despite this difference, dendritic spines were organized in an orchestrated manner such that the postsynaptic density (PSD) area per unit length of dendrite scaled positively with the dendritic diameter in CA1 proximal stratum radiatum (PSR), cortex, and CB. The ratio of the PSD area to neck length was kept relatively uniform across dendrites of different diameters in CA1 PSR. Computer simulation suggests that a similar level of synaptic strength across different dendrites in CA1 PSR enables the effective transfer of synaptic inputs from the dendrites toward soma. Excitatory postsynaptic potentials (EPSPs), evoked at single spines by glutamate uncaging and recorded at the soma, show that the neck length is more influential than head width in regulating the EPSP magnitude at the soma. Our study describes thorough morphologic features and the organizational principles of dendritic spines in different brain regions.
Dual functional modes for nanostructured p-Cu2O/n-Si heterojunction photodiodes

Many applications require a photodetector (PD) with multiple functional modes. This study demonstrates a dual functional PD with a simple structure that uses a nanostructured p-Cu2O/n-Si heterojunction. This device features a self-powering characteristic for an open-circuit voltage (V oc) of 0.5 V and exhibits an external quantum efficiency (EQE) of 3780% at a reverse bias of −5 V. There is a high EQE at low reverse-bias because trapped holes cause charge to be injected from the electrode. The nanostructured p-Cu2O/n-Si heterojunction also has a high response speed (<10 ms) in the self-powered mode because there is a built-in potential within p–n junction. This study shows that a nanostructured p-Cu2O/n-Si heterojunction acts as a self-powered PD for reducing power consumption and as a photomultiplication (PM)-type PD with high internal gain.
Efficacy of Banxia Xiexin decoction for chronic atrophic gastritis: A systematic review and meta-analysis

Background Banxia Xiexin decoction (BXD), a classical formula of traditional Chinese medicine (TCM), has been wildly used for chronic atrophic gastritis (CAG) patients with the cold-heat complex syndrome in China, and achieved satisfied effects. However, the clinical effects of it remains unclear. Purpose The purpose of this article is to evaluate the clinical efficacy and safety of BXD for CAG treatment. Methods We searched seven electronic databases including Ovid, Embase, PubMed, Cochrane Library, Wan-fang database, VIP (Chinese Scientific Journals Database) and CNKI (China National Knowledge Infrastructure) from their inception to September 21, 2020. We used Jadad scale and Cochrane Collaboration’s risk of bias tool to make evaluation of methodological quality. Revman 5.3 statistical software was used for statistical processing to evaluate the clinical efficacy and safety of BXD. Results 26 randomized controlled trials (RCTs) totaling 1985 patients were identified for analysis. Meta-analysis showed that BXD treatment was more effective (RR 1.29; 95%CI 1.24, 1.35; P<0.00001) and safe (MD 0.33; 95%CI 0.18, 0.58; P = 0.0002) than Chinese patent medicine + western medicine. Furthermore, BXD had improvement on symptoms scores such as stomach distending pain, and belching. Besides, BXD was more effective in inhibiting Helicobacter Pylori (HP), improving HP-related inflammation, and relieving the degree of glandular atrophy, intestinal metaplasia (IM), and dysplasia of gastric mucosa (GM). Conclusions The meta-analysis showed that BXD was more effective and safer for CAG patients than the control group. However, due to limitations of methodological quality and small sample size of the included studies, further standardized research of rigorous design should be needed.
New Numerical Interface Scheme for the Kurganov-Tadmor second-order Method

In this paper, we develop a numerical scheme to handle interfaces across computational domains in multi-block schemes for the approximation of systems of conservation laws. We are interested in transmitting shock discontinuities without lowering the overall precision of the method. We want to accomplish this without using information from interior points of adjacent grids, that is, sharing only information from boundary points of those grids. To achieve this, we choose to work with the second-order Kurganov-Tadmor (KT) method at interior points, relaxing it to first order at interfaces. This allows us to keep second-order overall accuracy (in the relevant norm) and at the same time preserve the TVD property of the original scheme. After developing the method we performed several standard one and two-dimensional tests. Among them, we used the one-dimensional advection and Burgers equations to verify the second-order convergence of the method. We also tested the two-dimensional Euler equations with an implosion and a Gresho vortex\cite{liska2003}. In particular, in the two-dimensional implosion test we can see that regardless of the orientation of shocks with respect to the interface, they travel across them without appreciable deformation both in amplitude and front direction.
Psychological Impact of Health Risk Communication and Social Media on College Students During the COVID-19 Pandemic: Cross-Sectional Study

Background The outbreak of COVID-19 began in 2019 and is expected to impact the psychological health of college students. Few studies have investigated the associations among health risk communication, social media, and psychological symptoms during a major pandemic. Objective The aim of this research was to assess the prevalence of psychological symptoms among college students and explore their associations with health risk communication and social media. Methods A web-based survey was distributed through the Wenjuanxing platform among Chinese college students from March 3-15, 2020. In addition to demographics, information on health risk communication and social media was collected, and the Symptom Checklist 90 Phobia and Health Anxiety Inventory subscale was used to assess psychological symptoms among 1676 college students in China. Multivariable logistic regression was performed to examine these independent risk factors. Results The prevalence of panic and health anxiety was 17.2% (288/1676) and 24.3% (408/1676), respectively. Regarding risk communication, understanding the risk of COVID-19 (odds ratio [OR] 0.480, 95% CI 0.367-0.627) was a protective factor against panic. Knowledge of prognosis (OR 0.708, 95% CI 0.551-0.910), preventive measures (OR 0.380, 95% CI 0.195-0.742), and wearing face masks (OR 0.445, 95% CI 0.230-0.862) were shown to be protective factors in predicting health anxiety. Perceived lethality (OR 1.860, 95% CI 1.408-2.459), being affected by the global spread (OR 1.936, 95% CI 1.405-2.669), and impact on social contacts (OR 1.420, 95% CI 1.118-1.802) were identified as significant risk factors associated with health anxiety. In terms of social media, trust in mainstream media (OR 0.613, 95% CI 0.461-0.816) was considered to be a protective factor against health anxiety. Conclusions There was a high prevalence of psychological symptoms among college students. Health risk communication and social media use were important in predicting psychological symptoms, especially health anxiety. Scientific and evidence-based information should be reported by social media platforms. Web-based consultation and intervention measures should be the focus of future studies.
