Cuantificación del contenido de ácido indolacético (AIA) en un caldo de fermentación microbiana

El Acido indol acetico (AIA) es una auxina natural presente en la mayoria de las plantas. Las auxinas son hormonas vegetales que regulan diversos procesos del desarrollo vegetal, por lo que su aplicacion en Agricultura es muy frecuente. Frente a la actual utilizacion de auxinas obtenidas por sintesis quimica, la sintesis microbiologica de estas sustancias resulta de gran importancia ya que la aplicacion de caldos de fermentacion que contienen auxinas, puede constituir una alternativa viable en el contexto de una agricultura ecologica. En este trabajo se muestra el estudio realizado para cuantificar el AIA presente en caldos de fermentacion obtenidos a partir de la bacteria Rhyzobium sp. 3. Utilizando un procedimiento de analisis de fitohormonas mediante HPLC desarrollado previamente, se ha puesto a punto un metodo para cuantificar AIA usando Acido indol propionico (AIP) como estandar interno. Se ha utilizado la tecnica de supresion ionica que evita la necesidad de obtener un derivado del compuesto a analizar. La deteccion se realizo por fluorescencia a una sensibilidad baja. Las muestras de caldos analizados mostraron un valor medio de AIA en el extracto de 29,0 ± 1,3 mg/mL. El metodo utilizado resulto ser lineal, sensible, preciso y exacto en el intervalo de concentracion estudiado, por lo que se considera adecuado para la cuantificacion de AIA a los niveles encontrados en los caldos fermentados
Medial Gastrocnemius Muscle Activity during Single-Leg Hopping to Exhaustion

Abstract This study described changes in leg muscle activation characteristics during exhaustive single-leg hopping. Twenty-seven healthy men performed trials (132 hops/min) to exhaustion, without a target height, to a target height with visual feedback and target height with tactile feedback. Mean muscle activation amplitude of the medial gastrocnemius (MG) decreased during the anticipatory period while duration of MG activity was maintained when hopping to a target height and contrasted the changes during hopping without a target height. Changes to MG activity were specific to whether the hopping height had been maintained or not. Changes during the anticipatory period of MG activity, indicative of adaptation in descending motor pathways, implicate utility of a motor learning strategy to allow completion of an exhaustive task.
Numerical taxonomic study of the genus Crotalaria L. (Crotalarieae, Fabaceae) in Nigeria

Abstract Numerical taxonomic study of the genus Crotalaria L. in Nigeria was conducted to identify and differentiate some of the species of the genus Crotalaria using numerical taxonomy based on quantitative and qualitative characters. Field work was conducted, where different species were collected and analyzed using multivariate analysis. The results showed that all the collected species are distinct at Euclidian distance of 0.41 in the cluster analysis with Cophenetic correlation (r)=0.964. The ordination analysis based on the results of the PCA, separated the specimens into 7 groups corresponding to the result of cluster analysis. The first two components of the PCA account for 81.5%. The length of petiole, width of leaflet and length of fruit contributed more to showing delimitation among the species.
Product Development, Manufacturing, and Packaging of Solid Dosage Forms Under QbD and PAT Paradigm: DOE Case Studies for Industrial Applications

An integrated approach based on QbD and PAT provides a systematic and innovative framework for product development, manufacturing, and quality risk management. In this context, the significance of the outcome of design of experiments (DOEs) to the selection of the product design, robust commercial manufacturing process, design space, and overall control strategy remains vital for the success of a drug product throughout its life cycle. This paper aims at discussing selected recent DOE case studies conducted during QbD-based and integrated QbD/PAT-based development of solid oral formulations and process improvement studies. The main focus of this paper is to highlight the rationales and importance of design selection during development and applications of mathematical models and statistical tools in analyzing DOE and PAT data for developing a design space, control strategy, and improved process monitoring. A total of 25 case studies (includes 9 PAT application studies) have been discussed in this paper which cover 11 manufacturing processes commonly utilized for solid dosage forms. Two case studies relevant to selection of packaging design for solid dosage forms are also briefly discussed to complete the scope. Overall, for a successful modern QbD approach, it is highly important that DOEs are conducted and analyzed in a logical sequence which involves designs that are phase-appropriate and quality-driven and facilitate both statistical and chemometric thinking at each development stage. This approach can result into higher regulatory flexibility along with lower economic burden during life cycle of a product, irrespective of regulatory path used (NDA or ANDA).
Optimizing functional outcome endpoints for stroke recovery studies

Novel therapeutic intervention that aims to enhance the endogenous recovery potential of the brain during the subacute phase of stroke has produced promising results. The paradigm shift in treatment approaches presents new challenges to preclinical and clinical researchers alike, especially in the functional endpoints domain. Shortcomings of the “neuroprotection” era of stroke research are yet to be fully addressed. Proportional recovery observed in clinics, and potentially in animal models, requires a thorough reevaluation of the methods used to assess recovery. To this end, this review aims to give a detailed evaluation of functional outcome measures used in clinics and preclinical studies. Impairments observed in clinics and animal models will be discussed from a functional testing perspective. Approaches needed to bridge the gap between clinical and preclinical research, along with potential means to measure the moving target recovery, will be discussed. Concepts such as true recovery of function and compensation and methods that are suitable for distinguishing the two are examined. Often-neglected outcomes of stroke, such as emotional disturbances, are discussed to draw attention to the need for further research in this area.
Double missense mutations in cardiac myosin‐binding protein C and myopalladin genes: A case report with diffuse coronary disease, complete atrioventricular block, and progression to dilated cardiomyopathy

Cardiomyopathies caused by double gene mutations are rare but conferred a remarkably increased risk of end‐stage progression, arrhythmias, and poor outcome. Compound genetic mutations leading to complex phenotype in the setting of cardiomyopathies represent an important challenge in clinical practice, and genetic tests allow risk stratification and personalized clinical management of patients. We report a case of a 50‐year‐old woman with congestive heart failure characterized by dilated cardiomyopathy, diffuse coronary disease, complete atrioventricular block, and missense mutations in cardiac myosin‐binding protein C (MYBPC3) and myopalladin (MYPN). We discuss the plausible role of genetic profile in phenotype determination.
Requirement of activating transcription factor 5 for murine fetal liver erythropoiesis

Activating transcription factor 5 (ATF5) is necessary for the development of various tissues, particularly under stress. Dysfunctions of ATF5 have been shown to be involved in many diseases. The exact function of ATF5 is tissue‐specific, and its role in erythropoiesis is still unknown. We here employed the loss of function strategy to investigate the role of ATF5 in murine erythropoiesis. We found that knockdown of Atf5 impaired the proliferation of fetal liver erythroid progenitors. Furthermore, erythroid differentiation was inhibited by ATF5 deficiency. Our study suggests that ATF5 may be a potential therapeutic target for treating blood diseases with ineffective erythropoiesis.
Cognitive remediation therapy modulates intrinsic neural activity in patients with major depression

Abstract Background Cognitive impairment is a core feature of major depressive disorder (MDD). Cognitive remediation may improve cognition in MDD, yet so far, the underlying neural mechanisms are unclear. This study investigated changes in intrinsic neural activity in MDD after a cognitive remediation trial. Methods In a longitudinal design, 20 patients with MDD and pronounced cognitive deficits and 18 healthy controls (HC) were examined using resting-state functional magnetic resonance imaging. MDD patients received structured cognitive remediation therapy (CRT) over 5 weeks. The whole-brain fractional amplitude of low-frequency fluctuations was computed before the first and after the last training session. Univariate methods were used to address regionally-specific effects, and a multivariate data analysis strategy was employed to investigate functional network strength (FNS). Results MDD patients significantly improved in cognitive function after CRT. Baseline comparisons revealed increased right caudate activity and reduced activity in the left frontal cortex, parietal lobule, insula, and precuneus in MDD compared to HC. In patients, reduced FNS was found in a bilateral prefrontal system at baseline (p < 0.05, uncorrected). In MDD, intrinsic neural activity increased in right inferior frontal gyrus after CRT (p < 0.05, small volume corrected). Left inferior parietal lobule, left insula, left precuneus, and right caudate activity showed associations with cognitive improvement (p < 0.05, uncorrected). Prefrontal network strength increased in patients after CRT, but this increase was not associated with improved cognitive performance. Conclusions Our findings support the role of intrinsic neural activity of the prefrontal cortex as a possible mediator of cognitive improvement following CRT in MDD.

MiR-511 mimic transfection inhibits the proliferation, invasion of osteosarcoma cells and reduces metastatic osteosarcoma tumor burden in nude mice via targeting MAPK1

Osteosarcoma, a highly aggressive cancer, can rapidly metastasize to distant organs such as lung, liver, brain. Despite much progress in the therapeutic regime has been made, the prognosis of osteosarcoma remains poor. In present study, microRNA-511 (miR-511) is lowly expressed in osteosarcoma cells, including MG63, U-2 OS, Saos-2 cells, while mitogen activated protein kinase1 (MAPK1) is highly expressed in osteosarcoma cells. Interestingly, MAPK1 might be a target of miR-511. We found that overexpression of miR-511 by miR-511 mimic transfection may result to low expression of MAPK1. Further study showed that miR-511 mimic inhibits the development of osteosarcoma MG63 cell, including proliferation and invasion. Moreover, miR-511 mimic transfection reduces metastatic osteosarcoma tumor burden in nude mice. These activities are mediated by targeting MAPK1. Our study provides a new sight for the molecular pathogenesis of osteosarcoma.
Cancer, sleep problems, and mind‐body medicine use: Results of the 2017 National Health Interview Survey

Sleep problems affect physical and emotional well‐being as well as immune system function. Evidence has demonstrated an improvement in sleep problems in patients with cancer through the use of mind‐body medicine (MBM). In the current study, the authors sought to elucidate the prevalence of sleep problems and the use of MBM in adult cancer survivors.
The Role of Hyperthermia in the Multidisciplinary Treatment of Malignant Tumors

Hyperthermia is often used in combination with chemotherapy and radiotherapy for cancer treatment. Recently, immunotherapy has become a popular research area, breaking exciting new ground with concurrent immunotherapy and hyperthermia. Much evidence has demonstrated the effectiveness of multidisciplinary synergistic therapy, and the underlying mechanism has been gradually explored. In this review, we focus on the mechanism of various cancer treatments in the current literature and recent advances in hyperthermia. Additionally, we review clinical studies of hyperthermia combined with other therapies in the previous 10 years and propose future prospects for hyperthermia in multidisciplinary synergistic therapy.

Design, Synthesis, Molecular Docking, and Cholinesterase Inhibitory Potential of Phthalimide‐Dithiocarbamate Hybrids as New Agents for Treatment of Alzheimer's Disease

A novel series of phthalimide‐dithiocarbamate hybrids was synthesized and evaluated for in vitro inhibitory potentials against acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). The anti‐cholinesterase results indicated that among the synthesized compounds, the compounds 7g and 7h showed the most potent anti‐AChE and anti‐BuChE activities, respectively. Molecular docking and dynamic studies of the compounds 7g and 7h, respectively, in the active site of AChE and BuChE revealed that these compounds as well interacted with studied cholinesterases. These compounds also possessed drug‐like properties and were able to cross the BBB.
Thermodynamic Assessment of Coating Materials for Solid-State Li, Na, and K Batteries.

The development of all solid-state batteries (ASSBs) presents a pathway to enhance the energy density and safety of conventional Li-ion batteries that use liquid electrolytes. However, one of the more promising categories of solid electrolytes (SEs), sulfides, are generally unstable in contact with common electrode materials, resulting in SE decomposition and high interfacial resistance. Recent studies have indicated that the application of coatings can, in some cases, stabilize the electrode/SE interface, reducing the likelihood for harmful interfacial reactions. Here, stable coatings for Li, Na, and K ASSBs are identified. In total, the stability windows for 1112 ternary alkali-metal-based compounds were assessed, including fluorides, chlorides, oxides, sulfides, phosphides, and nitrides. In general, the fluorides and chlorides exhibit the highest oxidative stability, suggesting they are good choices for stabilizing SE/cathode interfaces. In contrast, sulfides, phosphides, and nitrides exhibit much lower oxidative stabilities, with many of these materials predicted to decompose above 2 V. At the anode/SE interface, nitrides and oxides are predicted to be the most effective coatings, as they are generally the most stable against reductive decomposition. As expected, the sulfides and phosphides are the least stable class of materials under reducing conditions. Overall, the oxides appear to be the most versatile class of coating materials: several oxides are predicted to exhibit stability windows ranging from 0 to 3 V with respect to Li/Li+, Na/Na+, or K/K+. Examples of promising oxides for stabilizing the SE/anode interface include: Li5AlO4, Li4SiO4, NaAlO2, Na3PO4, KAlO2, and K3PO4. Similarly, promising compounds for stabilizing the SE/cathode interface include NaPO3 and KPO3. Finally, the possibility for kinetic stabilization suggests that additional ternary oxides (based, for example, on Ga, Nb, Sb, and Ta) may be viable coatings at the SE/cathode interface.
Ambient virtual scribes: Mutuo Health’s AutoScribe as a case study of artificial intelligence-based technology

Studies show that clinicians are increasingly burning out in large part from the clerical burden associated with using Electronic Medical Record (EMR) systems. At the same time, recently developed health data analytic algorithms struggle with poor quality free-text entered data in these systems. We developed AutoScribe using artificial intelligence–based natural language processing tools to automate these clerical tasks and to output high-quality EMR data. In this article, we describe the benefits and drawbacks of our technology. Furthermore, we describe how we are positioning our company’s culture within the existing healthcare system and suggest steps leaders of the system should consider in order to ensure that potentially transformative artificial intelligence–based technologies like ours are optimally adopted.
Abdominal compartment syndrome and intra-abdominal hypertension.

PURPOSE OF REVIEW Abdominal compartment syndrome (ACS) is a severe complication resulting from an acute and sustained increase in intra-abdominal pressure (IAP), causing significant morbidity and mortality. Although prospective double-blinded, randomized trials, and evidence-based analysis are lacking there is new evidence that still demonstrates high morbidity and mortality in critically ill populations because of intra-abdominal hypertension (IAH) in the 21st century. The objective of this review is to alert the health professional about this important diagnosis and to highlight the latest updates proposed by the World Abdominal Compartment Society. RECENT FINDINGS The present article reviews the clinical conditions of ACS and IAH and the latest updates from pathophysiology to the new management flowchart resulting from the implantation of point-of-care ultrasound in the monitoring and assistance of medical treatment of IAH/ACS. SUMMARY The present review emphasizes the importance of IAH in daily clinical practice and brings new WSACS updates on monitoring and treatment.
Chronotype, Social Jet Lag, and Cardiometabolic Risk Factors in Early Adolescence.

Importance Inadequate sleep duration and quality increase the risk of obesity. Sleep timing, while less studied, is important in adolescents because increasing evening preferences (chronotypes), early school start times, and irregular sleep schedules may cause circadian misalignment. Objective To investigate associations of chronotype and social jet lag with adiposity and cardiometabolic risk in young adolescents. Design, Setting, and Participants Starting in 1999, Project Viva recruited pregnant women from eastern Massachusetts. Mother-child in-person visits occurred throughout childhood. From January 23, 2012, to October 16, 2016, 804 adolescents aged 12 to 17 years completed 5 days or more of wrist actigraphy, questionnaires, and anthropometric measurements. A cross-sectional analysis using these data was conducted from April 31, 2018, to May 1, 2019. Exposures Chronotype, measured via a continuous scale with higher scores indicating greater evening preferences, and social jet lag, measured as the continuous difference in actigraphy sleep midpoint in hours from midnight on weekends vs weekdays, with higher values representing more delayed sleep timing on weekends. Main Outcomes and Measures Adiposity, measured via anthropometry and dual-energy x-ray absorptiometry. For a subset of 479 adolescents with blood samples, cardiometabolic risk scores were computed as the mean of 5 sex- and cohort-specific z scores for waist circumference, systolic blood pressure, inversely scaled high-density lipoprotein cholesterol, and log-transformed triglycerides and homeostatic model of insulin resistance. Results Among the 804 adolescents in the study, 418 were girls and 386 were boys, with a mean (SD) age of 13.2 (0.9) years. In multivariable models adjusted for age, puberty, season, and sociodemographics, associations of chronotype and social jet lag with adiposity varied by sex. For girls, greater evening preference was associated with a 0.58-cm (95% CI, 0.12-1.03 cm; P = .04 for interaction) higher waist circumference and 0.16 kg/m2 (95% CI, 0.01-0.31 kg/m2; P = .03 for interaction) higher fat mass index as measured by dual-energy x-ray absorptiometry; each hour of social jet lag was associated with a 1.19-cm (95% CI, 0.04-2.35 cm; P = .21 for interaction) higher waist circumference and 0.45 kg/m2 (95% CI, 0.09-0.82 kg/m2; P = .01 for interaction) higher fat mass index as measured by dual-energy x-ray absorptiometry. Associations of social jet lag and evening chronotypes persisted for many measures of adiposity after adjustment for sleep duration and other lifestyle behaviors. By contrast, no associations were observed in boys. There were no associations with the cardiometabolic risk score for either sex, although statistical power was low for this outcome. Conclusions and Relevance Evening chronotypes and social jet lag were associated with greater adiposity in adolescent girls but not adolescent boys. Interventions aimed at improving sleep schedules may be useful for obesity prevention, especially in girls.
THE IMPACT OF MEDICAID EXPANSION ON TRAUMA-RELATED EMERGENCY DEPARTMENT UTILIZATION: A NATIONAL EVALUATION OF POLICY IMPLICATIONS.

BACKGROUND The impact of the 2014 Affordable Care Act (ACA) upon national trauma-related emergency department (ED) utilization is unknown. We assessed ACA-related changes in ED use and payer mix, hypothesizing that post-ACA ED visits would decline and Medicaid coverage would increase disproportionately in regions of widespread policy adoption. METHODS We queried the National Emergency Department Sample (NEDS) for those with a primary trauma diagnosis, aged 18 to 64. Comparing pre-ACA (2012) to post-ACA (10/2014 to 09/2015), primary outcomes were change in ED visits and payer status; secondary outcomes were change in costs, discharge disposition and inpatient length of stay. Univariate and multivariate analyses were performed, including difference-in-differences analyses. We compared changes in ED trauma visits by payer in the West (91% in a Medicaid expansion state) versus the South (12%). RESULTS Among 21.2 million trauma-related ED visits, there was a 13.3% decrease post-ACA. Overall, there was a 7.2% decrease in uninsured ED visits (25.5% vs. 18.3%, p<0.001) and a 6.6% increase in Medicaid coverage (17.6% vs. 24.2%, p<0.001). Trauma patients had 40% increased odds of having Medicaid post-ACA (vs. pre-ACA: aOR 1.40, p<0.001). Patients in the West had 31% greater odds of having Medicaid (vs. South: aOR 1.31, p<0.001). The post-ACA increase in Medicaid was greater in the West (vs. South: aOR 1.60, p<0.001). Post-ACA, inpatients were more likely to have Medicaid (vs. ED discharge: aOR 1.20, p<0.001) and there was a 25% increase in inpatient discharge to rehabilitation (aOR 1.24, p<0.001). CONCLUSION Post-ACA, there was a significant increase in insured trauma patients and a decrease in injury-related ED visits, possibly resulting from access to other outpatient services. Ensuring sustainability of expanded coverage will benefit injured patients and trauma systems. LEVEL OF EVIDENCE Epidemiologic, level III.
