AbstractHigh-frequency Doppler (HFD) sounding is one of the major remote sensing techniques used for monitoring the ionosphere. Conventional systems for HFDs mainly utilize analog circuits. However, existing analog systems have become difficult to maintain as the number of people capable of working with analog circuits has declined. To solve this problem, we developed an alternate HFD receiver system based on digital signal processing. The software-defined radio (SDR) technique enables the receiver to be set up without the knowledge of analog circuit devices. This approach also downsizes the system and reduces costs. A highly stabilized radio system for both the transmitter and receiver is necessary for stable long-term observations of various phenomena in the ionosphere. The global positioning system disciplined oscillator with an accuracy of $${10}^{-11}$$

compensates for the frequency stability required by the new receiving system. In the new system, four frequencies are received and signal-processed simultaneously. The dynamic range of the new system is wider (> 130 dB) than that of the conventional system used in HFD observations conducted by the University of Electro-Communications in Japan. The signal-to-noise ratio significantly improved by 20 dB. The new digital system enables radio waves to be received with much smaller amplitudes at four different frequencies. The new digital receivers have been installed at some of the stations in the HFD observation network in Japan and have already captured various ionospheric phenomena, including medium-scale traveling ionospheric disturbances and sudden commencement induced electric field fluctuations, which indicates the feasibility of SDR for actual ionospheric observations. The new digital receiver is simple, inexpensive, and small in size, which makes it easy to deploy new receiving stations in Japan and elsewhere. These advantages of the new system will help drive the construction of a wide HFD observation network.

Abstracts
Background
Dyslipidemia is an aberrant rise in blood lipids due to diet and lifestyle. It has implicated as the major risk factor for developing hypertension among other diseases. This study was designed to evaluate plantain based dough meal nutritional property, antioxidant activity and dyslipidemia ameliorating potential in high-fat induced rats.

Methods
The flour blends, i.e., PSC (Plantain 70%, Soycake 30%), PSR (Plantain 65%, Soycake 30%, Rice-bran 5%), PSO (Plantain 65%, Soycake 30%, Oat-bran 5%), PSRO (Plantain 60%, Soycake 30%, Rice-bran 5%, Oat-bran 5%) and controls (100% Plantain flour & Cerolina) were evaluated for chemical, antioxidants and antihyperlipidemia.

Results
Protein, fiber and energy composition varied from 2.2–4.97 g/100 g, 16.44–19.59 g/100 g and 369.7–385.5 kcal/100 g, respectively. Essential amino acid index and predicted-biological values of the foods ranged from 68.31–76.31% and 62.19–71.48%, respectively. Phenolic profiles (mg/g) were gallic acid (25.33–31.26), caffeic acid (2.75–4.61), ferulic acid (5.16–12.73), luteolin (16.31–23.60), kaempferol (21.51–30.64), quercetin (24.28–37.13), chlorogenic acid (42.25–59.78), myricetin (28.41–38.41), 3,5-dicaffeoylquinic acid (27.17–41.59) and 4, 5-dicaffeoylquinic acid (39.96–51.28). The antioxidant activity of PSRO on ABTS, DPPH, FRAP, Fe2+ chelation and OH free radicals was higher than other foods. Atherogenic index, coronary risk index and log (TG/HDL-conc.) of rats fed on experimental foods were lower than recommended values.

Conclusion
The study established that PSRO had higher antioxidant and anti-hyperlipidemia properties; hence, it may be suitable as a functional food.

Published: November 2021

AbstractBackgroundParaganglioma of the urinary bladder is a very rare benign tumor that constitutes less than 0.5% of all bladder tumors. It can be functional and non-functional. Functional tumors present with symptoms of catecholamine excess, and non-functional tumors usually remain asymptomatic.Case presentationHere, we present a case of non-functional urinary bladder paraganglioma in a 36-year-old female who presented to us with a history of intermittent hematuria. The routine hematological and biochemical parameters were within normal limits. Diagnostic computed tomography (CT) revealed a hypervascular lesion in the urinary bladder dome with no significant uptake in gallium-68-labelled-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid peptides-NaI3-octreotide positron emission tomography (DOTA-NOC PET/CT). Histopathology and immunohistochemistry confirmed the diagnosis of paraganglioma.ConclusionWe present this case because of the rare location of paraganglioma in the urinary bladder and being non-functional with low/absent somatostatin receptor expression.
Unravelling the large-scale circulation modes in turbulent Rayleigh-Bénard convection

Authors: Horn Susanne , Schmid Peter J. , Aurnou Jonathan M. 
Published: November 2021

Abstract
The large-scale circulation (LSC) is the most fundamental turbulent coherent flow structure in Rayleigh-Bénard convection. Further, LSCs provide the foundation upon which superstructures, the largest observable features in convective systems, are formed. In confined cylindrical geometries with diameter-to-height aspect ratios of

, LSC dynamics are known to be governed by a quasi-two-dimensional, coupled horizontal sloshing and torsional (ST) oscillatory mode. In contrast, in

cylinders, a three-dimensional jump rope vortex (JRV) motion dominates the LSC dynamics. Here, we use dynamic mode decomposition (DMD) on direct numerical simulation data of liquid metal to show that both types of modes co-exist in

and

cylinders but with opposite dynamical importance. Furthermore, with this analysis, we demonstrate that ST oscillations originate from a tilted elliptical mean flow superposed with a symmetric higher-order mode, which is connected to the four rolls in the plane perpendicular to the LSC in

tanks.

Objectives:
The aim of this exploratory study was to evaluate whether three-dimensional texture analysis (3D-TA) features of non-contrast-enhanced T 1 weighted MRI associate with traditional prognostic factors and disease-free survival (DFS) of breast cancer.

Methods:
3D-T 1 weighted images from 78 patients with 81 malignant histopathologically verified breast lesions were retrospectively analysed using standard-size volumes of interest. Grey-level co-occurrence matrix (GLCM)-based features were selected for statistical analysis. In statistics the Mann–Whitney U and the Kruskal–Wallis tests, the Cox proportional hazards model and the Kaplan–Meier method were used.

Results:
Tumours with higher histological grade were significantly associated with higher contrast (1 voxel: p = 0.033, 2 voxels: p = 0.036). All the entropy parameters showed significant correlation with tumour grade (p = 0.015–0.050) but there were no statistically significant associations between other TA parameters and tumour grade. The Nottingham Prognostic Index (NPI) was correlated with contrast and sum entropy parameters. A higher sum variance TA parameter was a significant predictor of shorter DFS.

Conclusion:
Texture parameters, assessed by 3D-TA from non-enhanced T 1 weighted images, indicate tumour heterogeneity but have limited independent prognostic value. However, they are associated with tumour grade, NPI, and DFS. These parameters could be used as an adjunct to contrast-enhanced TA parameters.

Advances in knowledge:
3D-TA of non-contrast enhanced T 1 weighted breast MRI associates with tumour grade, NPI, and DFS. The use of non-contrast 3D-TA parameters in adjunct with contrast-enhanced 3D-TA parameters warrants further research.

Published: November 2021

Background Poor communication at the time of patient handover is recognized as a root cause of a considerable proportion of preventable deaths. Despite several advantages, the Patient Care Report (PCR) implementation may include insufficient details for demonstrating the functional status of the patients during the actual response which can further prolong the response time. Healthcare entities have been emphasizing the need to implement e-PCR systems. This systematic review aimed to examine the impact of e-PCR systems on reducing response time of prehospital care. Methods Literature search was carried out using the relevant search terms and keywords with inclusion and exclusion criteria. N=6 researchers that focused on the impact of e-PCR systems on reducing response time of prehospital medical care were included within this review. Results The findings indicated that ePCR implementation led to prominent improvements in the quality of the care services provided by the healthcare organisation. Additionally, ePCR reduces the response rate by data standardization. Conclusion The implementation of e-PCR systems ensures the availability of records and automates reporting on given quality metrics. Moreover, the implementation of e-PCR systems also improved response time and increased the out of hospital rates of survival. However, fear of increasing the ambulance run time, compromise on the availability of ambulance, and challenges in integration with the existing information systems implemented within the hospitals, were some of the most common challenging situations associated with implementing e-PCR systems.

Los tlacuaches son animales nocturnos, generalistas y oportunistas; no obstante, se conoce poco de su conducta en vida silvestre, ya que la mayoría de los estudios existentes son en cautiverio. En esta nota se reporta la conducta de Didelphis sp. en vida silvestre utilizando fotos y videos de una cámara trampa, resaltando el uso de la cola para transportar material. En el Cañón del Usumacinta, Estado de Tabasco, México, se colocó una cámara trampa el 8 de abril de 2020; se dejó funcionando y programada para tomar fotografías y videos. Se revisó el 2 de mayo del mismo año, identificando y separando los archivos correspondientes a Didelphis sp. Se identificó la conducta observada, considerando la hora y el sexo de cada individuo identificado. Se obtuvieron 209 registros de fauna silvestre, de los cuales 55 correspondieron a Didelphis sp., todos capturados durante la noche. Se identificaron 5 conductas principales dentro de las que destacan el tránsito con crías en el lomo y el transporte de material vegetal con la cola, probablemente hojas de garabato (Celtis iguanaea) para la construcción del nido. La mayoría de las conductas observadas corresponden al forrajeo; sin embargo, se reporta, por primera vez para México, el comportamiento de transportar material vegetal con la cola, presumiblemente para construir su nido. También, se reportan 3 picos de actividad durante la noche y se observa a una hembra con crías en el marsupio y posteriormente en su lomo.

El tlacuache de Virginia (Didelphis virginiana) es hospedero para una variedad de pulgas que pueden ser importantes vectores para la transmisión de enfermedades, incluyendo zoonosis; por lo tanto, es importante generar conocimiento sobre las pulgas que parasitan a este animal. En este trabajo, presentamos la lista de pulgas que parasitan a los tlacuaches, con la adición de una especie que no ha sido registrada previamente en D. virginiana, ni en otros marsupiales. Colectamos pulgas de tlacuaches de Virginia en el área urbana de la Ciudad de México, México, y también realizamos una búsqueda bibliográfica para determinar las especies de pulgas reportadas previamente. Encontramos registros de 26 especies de pulgas en los tlacuaches y añadimos a esta lista la especie de pulga Plusaetis sibynus. Plusaetis sibynus es una pulga común en roedores (principalmente Peromyscus y Neotoma), por lo que representa un vector potencial para la transmisión de enfermedades de estos roedores a los tlacuaches, y posteriormente a las poblaciones humanas. Se requieren más estudios para determinar el papel de esta pulga como vector de enfermedades zoonóticas.
Report of white-nosed coati (Nasua narica) rubbing itself with feces of tayra (Eira barbara) in Costa Rica
Authors: Fleming Frank , Weldon Paul J. 
Published: November 2021

Se sabe que los coatis cautivos (Nasua sp.) frotan su pelaje con diversos materiales antropogénicos, como productos químicos manufacturados como jabones y plantas no nativas. Sin embargo, poco se sabe de su comportamiento de unción o de los materiales de unción que utilizan en la naturaleza. Registramos las actividades de los mamíferos en libertad en un claro del bosque en Costa Rica utilizando una cámara automática ScoutGuard SG565F equipada con un flash blanco incandescente de largo alcance para grabar imágenes nocturnas. Obtuvimos un registro de un macho de tayra (Eira barbara), un mustélido omnívoro, que defecó en un árbol caído en un claro del bosque. Posteriormente, 4.3 días después, un coatí de nariz blanca (Nasua narica) macho adulto se acercó y tocó las heces de tayra con su hocico y sus patas delanteras. Luego mordió un bolo fecal, lo llevó en su boca a la base de su cola y lo frotó en su cola usando rápidos movimientos alternos de sus patas delanteras. Ésta es una documentación poco común del frotamiento del pelaje por un prociónido con materiales naturales y del uso de heces para la unción por parte de un mamífero.

Published: November 2021

AimsCam and pincer morphologies are potential precursors to hip osteoarthritis and important contributors to non-arthritic hip pain. However, only some hips with these pathomorphologies develop symptoms and joint degeneration, and it is not clear why. Anterior impingement between the femoral head-neck contour and acetabular rim in positions of hip flexion combined with rotation is a proposed pathomechanism in these hips, but this has not been studied in active postures. Our aim was to assess the anterior impingement pathomechanism in both active and passive postures with high hip flexion that are thought to provoke impingement.MethodsWe recruited nine participants with cam and/or pincer morphologies and with pain, 13 participants with cam and/or pincer morphologies and without pain, and 11 controls from a population-based cohort. We scanned hips in active squatting and passive sitting flexion, adduction, and internal rotation using open MRI and quantified anterior femoroacetabular clearance using the β angle.ResultsIn squatting, we found significantly decreased anterior femoroacetabular clearance in painful hips with cam and/or pincer morphologies (mean -11.3° (SD 19.2°)) compared to pain-free hips with cam and/or pincer morphologies (mean 8.5° (SD 14.6°); p = 0.022) and controls (mean 18.6° (SD 8.5°); p < 0.001). In sitting flexion, adduction, and internal rotation, we found significantly decreased anterior clearance in both painful (mean -15.2° (SD 15.3°); p = 0.002) and painfree hips (mean -4.7° (SD 13°); p = 0.010) with cam and/pincer morphologies compared to the controls (mean 7.1° (SD 5.9°)).ConclusionOur results support the anterior femoroacetabular impingement pathomechanism in hips with cam and/or pincer morphologies and highlight the effect of posture on this pathomechanism.

Published: November 2021

AimsThis study investigates head-neck taper corrosion with varying head size in a novel hip simulator instrumented to measure corrosion related electrical activity under torsional loads.MethodsIn all, six 28 mm and six 36 mm titanium stem-cobalt chrome head pairs with polyethylene sockets were tested in a novel instrumented hip simulator. Samples were tested using simulated gait data with incremental increasing loads to determine corrosion onset load and electrochemical activity. Half of each head size group were then cycled with simulated gait and the other half with gait compression only. Damage was measured by area and maximum linear wear depth.ResultsOverall, 36 mm heads had lower corrosion onset load (p = 0.009) and change in open circuit potential (OCP) during simulated gait with (p = 0.006) and without joint movement (p = 0.004). Discontinuing gait’s joint movement decreased corrosion currents (p = 0.042); however, wear testing showed no significant effect of joint movement on taper damage. In addition, 36 mm heads had greater corrosion area (p = 0.050), but no significant difference was found for maximum linear wear depth (p = 0.155).ConclusionLarger heads are more susceptible to taper corrosion; however, not due to frictional torque as hypothesized. An alternative hypothesis of taper flexural rigidity differential is proposed. Further studies are necessary to investigate the clinical significance and underlying mechanism of this finding.

Historical approach on the creation of the Femicide Law in Brazil
Authors: De Albuquerque Farias Athena 
Published: November 2021

Historicamente, a sociedade brasileira incorporou os ditames de uma estrutura patriarcal. Essa estrutura patriarcal é essencialmente sexista, onde as figuras masculinas se destacam e carregam um sentimento de dominação e poderio sobre as mulheres. O presente estudo visa analisar os aspectos históricos e socioculturais que levaram o Brasil a editar a Lei do Feminicídio. Nessa luta contra a violência contra as mulheres, os movimentos feministas têm sido um dos maiores colaboradores. A criação do tipo penal do feminicídio é, portanto, considerado um marco político e acadêmico para o feminismo, pois conferiu visibilidade para as crescentes mortes de pessoas do sexo feminino em razão do gênero. A edição da lei teve o objetivo de reduzir os crimes contra as mulheres em razão do gênero, com a modificação do julgamento e aumento das penas para este tipo penal, com intenção de inibir novas práticas delituosas, assim como de criar consciência na sociedade sobre a morte letal de mulheres e como isso afeta a sociedade.

There has been an exponential growth in the field of molecular oncology and cutting-edge research has enabled us to develop a better understanding of therapeutically challenging nature of cancer. Based on the mechanistic insights garnered from decades of research, puzzling mysteries of multifaceted nature of cancer have been solved to a greater extent. Our rapidly evolving knowledge about deregulated oncogenic cell signaling pathways has allowed us to dissect different oncogenic transduction cascades which play critical role in cancer onset, progression and metastasis. Pharmacological targeting of deregulated pathways has attracted greater than ever attention in the recent years. Henceforth, discovery and identification of high-quality biologically active chemicals and products is gaining considerable momentum. There has been an explosion in the dimension of natural product research because of tremendous potential of chemopreventive and pharmaceutical significance of natural products. Schisandrin is mainly obtained from Schisandra chinensis. Schisandrin has been shown to be effective against different cancers because of its ability to inhibit/prevent cancer via modulation of different cell signaling pathways. Importantly, regulation of non-coding RNAs by schisandrin is an exciting area of research that still needs detailed and comprehensive research. However, we still have unresolved questions about pharmacological properties of schisandrin mainly in context of its regulatory role in TGF/SMAD, SHH/GLI, NOTCH and Hippo pathways.

AbstractIn this paper, we introduce a new type of a generalized split monotone variational inclusion (GSMVI) problem in the framework of real Hilbert spaces. By incorporating an inertial extrapolation method and an Halpern iterative technique, we establish a strong convergence result for approximating a solution of GSMVI and fixed point problems of certain nonlinear mappings in the framework of real Hilbert spaces. Many existing results are derived as corollaries to our main result. Furthermore, we present a numerical example to support our main result and propose an open problem for interested researchers in this area. The result obtained in this paper improves and generalizes many existing results in the literature.
