Unlocking the Origins of Ultracool Dwarf Radio Emission
Authors: Hughes A. G. , Boley A. C. , Osten R. A. , White J. A. , Leacock M. 
Published: July 2021

Abstract
Empirical trends in stellar X-ray and radio luminosities suggest that low-mass ultracool dwarfs (UCDs) should not produce significant radio emission. Defying these expectations, strong nonthermal emission has been observed in a few UCDs in the 1–10 GHz range, with a variable component often attributed to global aurorae and a steady component attributed to other processes, such as gyrosynchrotron emission. While both auroral and gyrosynchrotron emission peak near the critical frequency, only the latter radiation is expected to extend into millimeter wavelengths. We present Atacama Large Millimetre/Submillimeter Array (ALMA) 97.5 GHz and Very Large Array 33 GHz observations of a small survey of 5 UCDs. LP 349-25, LSR J1835+3259, and NLTT 33370 were detected at 97.5 GHz, while LP 423-31 and LP 415-20 resulted in nondetections at 33 GHz. A significant flare was observed in NLTT 33370, which reached a peak flux of 4880 ± 360 μJy, exceeding the quiescent flux by nearly an order of magnitude and lasting 20 s. These ALMA observations show bright 97.5 GHz emission with spectral indices ranging from α = 0.76 to α = −0.29, suggestive of optically thin gyrosynchrotron emission. If such emission traces magnetic reconnection events, then this could have consequences for both UCD magnetic models and the atmospheric stability of planets in orbit around them. Overall, our results provide confirmation that gyrosynchrotron radiation in radio-loud UCDs can remain detectable into the millimeter regime.
RR Lyrae Stars in Stellar Streams with Gaia: The Escapers
Authors: Abbas Mohamad , Grebel Eva K. , Simunovic Mirko 
Published: July 2021

Abstract
We attempt to identify RR Lyrae (RRL) stars in stellar streams that might have escaped from seven globular clusters (GCs) based on proper motions, distances, color–magnitude diagrams, and other properties extracted from the Gaia Early Data Release 3 (EDR3) database. Specifically, we cross-match two large RRL stars catalogs (from Gaia DR2 and Catalina Sky Survey) with each other and with the EDR3 database, and we end up with a sample of ∼150,000 unique RRL stars. We calculate distances to RRL stars using the M

G
–[Fe/H] and M

V
–[Fe/H] absolute magnitude–metallicity relations and adopt [Fe/H] values for the GCs from different spectroscopic studies. We also constrain our search to areas where stellar streams associated with GCs were previously suggested or identified in other studies. We identify 24 RRL stars that might have escaped from the following seven GCs: Palomar 13 (Pal 13), NGC 6341 (M92), NGC 5904 (M5), NGC 5466, NGC 1261, NGC 288, and NGC 1851. We list our findings in Table 2.
Effort de conservation et Aires marines protégées : quatre illusions et un changement de perspective
Authors: Beuret Jean-Eudes , Cadoret Anne 
Published: July 2021

Dans les argumentaires politiques et parfois scientifiques, l’effort consenti pour la conservation des milieux marins via les aires marines protégées (AMP) est évalué sur la base des surfaces classées, ce qui sous-entend que leur statut offre une protection à l’échelle de leur périmètre. Plus généralement, les AMP reposeraient sur quatre piliers : un statut, un périmètre, des règles, un gestionnaire. Une analyse comparative internationale interdisciplinaire (géographie et économie), fondée sur 13 cas étudiés dans des contextes géographiques et sociétaux très différenciés, nous conduit à revenir sur quatre illusions fondatrices selon lesquelles : a) le statut marque l’institutionnalisation de l’AMP et offre une protection ; b) au périmètre de l’AMP correspond l’espace géré et protégé ; c) des règles spécifiques sont nécessaires à l’action de conservation et sont conçues de façon à les faire respecter via des sanctions ; et d) la mise en œuvre de la politique territoriale de conservation suppose une centralité, avec un gestionnaire disposant ou non d’une autorité. À ces quatre illusions, qualifiées respectivement de statutaires, surfacique, normative et centralisatrice correspondent des réalités plus complexes illustrées par les cas d’étude. Leur analyse nous conduit à préciser ce que sont les AMP, à en tirer des enseignements pour l’accompagnement des processus d’institutionnalisation des AMP, puis à proposer de nouvelles modalités et indicateurs d’évaluation de l’effort consenti en faveur de la conservation.
Protéger la biodiversité marine : regard sur la Méditerranée au prisme des outils de l’UICN
Authors: Crouteix  Orianne 
Published: July 2021

La mer Méditerranée réunit de forts enjeux économiques (transports mondiaux, tourisme, pêche), sociaux (immigration) et environnementaux (hotspot de biodiversité, et zone fortement impactée par le changement climatique). Cette petite mer semi-fermée apparaît alors comme un espace adapté pour interroger deux outils de protection environnementale du milieu marin : les listes rouges de l’Union internationale pour la conservation de la nature (UICN) et les aires protégées. Cette étude s’attache à comprendre la mise en place de ces deux outils sur le milieu marin, après avoir analysé l’émergence des enjeux environnementaux dans les arènes politiques et scientifiques. Basée sur une méthodologie regroupant observation participante au sein d’une institution vouée à la protection des espaces insulaires de Méditerranée, entretiens semi-directifs et analyses de documents, cette étude propose une réflexion s’appuyant sur des concepts et des cadres d’analyses développés par les science studies, les sciences de gestion et la géographie. L’objectif est d’analyser la construction des enjeux environnementaux en formalisant une dynamique cyclique reliant objet scientifique et sujet environnemental politique. Les enjeux marins sont repositionnés dans cette dynamique en étudiant plus particulièrement la place des incertitudes. L’objectif de l’étude est d’interroger la pertinence du transfert des deux outils utilisés dans les politiques de protection de la biodiversité (listes rouges et aires protégées) du milieu terrestre vers le milieu marin. Ces outils ne s’adaptent pas aussi facilement au milieu marin où les données naturalistes sont moindres et les usages peu compatibles avec certains objectifs des aires protégées.
Quand la trajectoire d’objets techniques liés à la gestion des eaux agricoles révèle des valeurs attachées à la nature
Authors: Seguin Laura , Barataud Fabienne 
Published: July 2021

À partir d’une enquête qualitative, dans un contexte d’agriculture intensive en Brie humide drainée, l’article retrace la manière dont est pensée la mise en discussion de deux objets techniques (le système de drainage et les zones tampons humides artificielles). Il examine comment ces objets sont « apportés » sur ces territoires par les pouvoirs publics et les scientifiques et ce qu’ils révèlent des représentations et valeurs attachées à la fois à la technique et à la nature. Le travail met en évidence que s’il y a certes émergence de nouveaux paradigmes d’action publique fondés sur l’expression de nouvelles attentes sociales (notamment au travers d’un impératif de participation) et environnementales, l’adoption de ces deux objets dessine de manière similaire une forme de confiance en la technique et un souci de maîtrise de la nature.

Authors: Dissanayake A. D. , Samaratunge U. Y. , Piyadigama I. , Gunawardena K. 
Published: July 2021

Introduction: Intravenous oxytocin (IVO) is recommended during elective caesarean section to prevent postpartum haemorrhage. However, compared to IVO intramyometrial oxytocin (IMO), may result in better contractility with minimal haemodynamic side effects. Limited number of studies are available on IMO use at elective Caesarean section (CS). Objective: To evaluate the effectiveness of prophylactic IMO against IVO, in term singleton mothers at elective CS. Methods: Sixty five term singleton mothers undergoing elective CS at the Teaching Hospital, Kandy from 1st February 2015 to April 2015 were randomized to IMO and IVO. Prior to umbilical cord clamping, either IMO 5 IU divided half to each cornu or routine IVO 5 IU was administered. Blood loss was assessed using gravimetric methods and allowable blood loss calculation. Surgeon assessed uterine tone at 2,5,10 and 15 minutes following injection and gave a score of 1 to 5. Hameodynamic parameters, side effects, haemoglobin and haematocrit were recorded. Results: Thirty three were in IMO group while 32 were in IVO group. There was no significant difference between IVO and IMO groups in relation to mean blood loss, (303.83, SD 103.77ml vs 267.65 SD 93.53 ml, p=0.43), uterine contractions at 2 and 5 minutes and side effects. Calculated allowable blood loss in IMO group was significantly less than IVO group (p=0.04) and contraction scores at 10 and 15minutes were significantly higher in IMO group. There was no difference in haemodynamic parameters in each group. Conclusion: IMO oxytocin was not more effective than IVO during elective CS.

Published: July 2021

Introduction
Hysterectomy is a reasonably safe, common and routine surgical procedure which rarely leads to perioperative death. Minor complications including postoperative infections, fever, wound hematomas or wound separation occur in approximately 25% of patients.

Objective
A comparative assessment of the post-operative outcomes of Sri Lankan patients subjected to Total Abdominal Hysterectomy and Ascending Vaginal Hysterectomy for benign uterine diseases.
Methods
A randomized controlled trial was conducted on 60 patients who underwent hysterectomy from July 2013 to June 2014, in a tertiary care hospital. Women those who were waiting for hysterectomy for benign uterine diseases within age 35-55yrs were included for the study.30 patients were underwent abdominal hysterectomy and 30 patients were underwent vaginal hysterectomy. Five main variables were measured such as operative time in minutes, blood loss, post operative pain, pyrexia, hospital stay in days. Data entered and analyzed by SPSS 25.0.

Result
Age of participants was between 37 years of age to 51 years of age. Mean age was 44.87 years among Vaginal Hysterectomy group (SD 3.4 years) and 44.71 among Abdominal Hysterectomy group (SD 3.756 years).

Published: July 2021

Abstract

Objectives:
We aimed to examine the protective effects of dapagliflozin (dapa) on thoracic aortic constriction (TAC)-induced heart failure in a nondiabetic mouse model. More specifically, we determined the effects of dapa on uncoupling protein 3 (UCP3) activation and subsequent metabolic remodeling.

Methods:
Sixty C57BL/6J mice were divided into six groups for TAC surgery and received different doses of dapa via gavage for 4 weeks. Echocardiography was performed to evaluate cardiac structure and function. Histological and molecular markers of cardiac remodeling and metabolic changes were assessed through staining assays, RT-PCR, western blot, and ELISA. HL-1 cells were used to explore the role of UCP3 in metabolic remodeling through transfection with UCP3 siRNA.

Results:
Mice that received TAC exhibited elevated heart weight/body weight ratios (HW/BW), left ventricular (LV) hypertrophy, impaired LV ejection fraction, and increased rates of fibrosis and apoptosis, unlike mice that received sham operation. Treatment with dapa after TAC restored HW/BW, improved LV parameters, and reduced fibrosis and apoptosis. dapa changed the expression levels of enzymes involved in glucose and fatty acid (FA) metabolism, such as pyruvate dehydrogenase lipoamide kinase isozyme 4, glucose transporter 4, carnitine palmitoyltransferase-1α, carnitine O-acetyltransferase, carnitine O-octanoyltransferase, acyl-CoA thioesterase 1, acyl-CoA thioesterase 2, peroxisome proliferator-activated receptors α and β, proliferator-activated receptor-gamma coactivator-1α, and UCP3, relative to the levels in mice in the TAC group. UCP3 siRNA reduced the expression of AMP-activated protein kinase and of factors involved in FA oxidation in vitro.

Conclusions:
Dapa exhibits cardioprotective effects in the model and augments expression of UCP3, which may be involved in metabolic remodeling in the failing heart.

Published: July 2021

Abstract

Objectives:
This study aimed to diversify the spectrum of PRKAG2 variants and explore its clinical features in a Chinese Han population with hypertrophic cardiomyopathy (HCM).

Methods:
Whole-exome sequencing was performed on 200 patients diagnosed with HCM, and four causative PRKAG2 variants were identified in the probands and their relatives using Sanger sequencing. Their clinical manifestations, laboratory examinations, therapeutic methods, and outcomes were documented and analyzed.

Results:
Four variants were identified in six probands and seven of their relatives. Left ventricular hypertrophy was present in all probands. Five probands had sinus bradycardia, three had implanted pacemakers (PM), one developed heart failure, two had ventricular preexcitation, and one had atrial fibrillation.

Conclusions:
PRKAG2 cardiac syndrome (PCS) is a rare autosomal dominant disease characterized by ventricular hypertrophy, preexcitation, and progressive conduction defects, resulting in a high incidence of PM implantation. Genetic testing provides robust information for distinguishing PCS from sarcomeric HCM, which will be beneficial in guiding therapy and improving prognosis.

Authors: Tonui J. , Chepkutto W. , Rotich J. 
Published: July 2021

Coronavirus disease 2019 (COVID-19) pandemic began in December 2019 in Wuhan City China where it is believed to have been transmitted to humans from an unknown animal species. The public health, social and economic impact of the pandemic world over is detrimental. Health care providers at the frontline in the fight against COVID-19 are at the greatest risk of infection and so far, many have been infected and some have already died from the disease. Thus, it is imperative that healthcare providers have adequate knowledge of infectious diseases and microbial pathogens to comprehend the scale of risk for better recognition and response. Microbiological concepts of infection prevention and control, hand hygiene and aseptic techniques are essential in slowing down the spread of the virus. COVID-19 has proven that infectious agents can emerge from any region in the world and can spread rapidly with ominous consequences to all humanity. This narrative review discusses the role of college-learnt microbiology in health care provider preparedness for emerging infectious diseases in light of the current pandemic.

Abstract. This study aims to analyze the convergent validity of an instrument for the three-dimensional measurement of mood states: the POMS-VIC. The instrument was applied to 62 students from the UAM Sports Service. The scores offered by the athletes when completing the POMS-VIC and other similar tests (PIED) Interactive Profile of Moods, (Barrios & González, 2012); (STAI) State-Trait Anxiety Inventory (Guillén-Riquelme & Buela-Casal, 2011) and (CSAI-2R) Revised Competitive State Anxiety Inventory-2 (Andrade et al., 2007) were compared. The correlation coefficient was calculated by Spearman rank and non-parametric group contrast using the Mann Whitney U test. Appreciating mean correlations between PIED and POMS_Intensidad (rho=-.61), POMS_Valencia (rho=.34) and POMS_Control (rho=.43). As well as between POMS_Intensidad and the three subscales of CSAI (Cognitive, rho=-.31), (Somatic, rho=-.55) and (Selfconfidence, rho=.56). It is concluded that there is a considerable relationship between the POMS-VIC and the considered instruments. This result implies that the proposal scale is valid for the mood state measurement and allows its use in the sports field. Therefore, the instrument is considered to have an important practical impact for sport psychology.
