This research aimed to study the chemical composition of Aloysia citrodora methanolic extract and its biological activities as an antioxidant, and its antibacterial, antifungal and anti-inflammatory activities based on four bioclimatic collection stages. The contents of total phenols, total flavonoids and total tannins were determined. Nine phenolic compounds were identified by LC-DAD–ESI-MS/MS. The major compound was acteoside, a phenylpropanoid which represented about 80% of the methanolic fraction in the various regions. The antioxidant activities of different locations were measured by different analytical assays, such as DPPH, ABTS and iron reducing power. The results showed that phenolic compounds and antioxidant activities varied with climatic and environmental factors. Moreover, there was a significant dependency between regions and biological activities. The use of a principal component analysis showed that there was a close relationship among phenylpropanoids, phenolic compounds and the studied biological activities.

Introdução. Distúrbios neurológicos são capazes de causar comprometimento no desempenho funcional, como a dificuldade da manutenção do equilíbrio, exigindo um tratamento a longo prazo, e a telereabilitação favorece a continuidade do tratamento à distância. Objetivo. Verificar se a telereabilitação é efetiva no treino de equilíbrio de pacientes com disfunção neurológica. Método. Trata-se de uma revisão de literatura, em que foi realizado busca nas bases de dados PubMed, Cochrane Library, Biblioteca Virtual de Saúde, Scielo e PEDro, no mês de setembro de 2020, sendo a busca atualizada em março de 2021. Resultados. Foram incluídos 7 ensaios clínicos controlados realizados entre 2004 e 2020. Para os desfechos de equilíbrio estático e dinâmico, dois estudos mostraram que o grupo de telereabilitação apresentou melhora superior do que o grupo controle, enquanto, os demais obtiveram efeitos semelhantes. Quando avaliado o nível de confiança de equilíbrio, apenas um de dois estudos apresentou melhoras significativas. Para a adesão e satisfação avaliada em três estudos, um obteve boa satisfação e dois não tiveram diferenças quanto ao grupo controle. Conclusões. Telereabilitação é uma forma eficaz para o treinamento de equilíbrio de pacientes com disfunção neurológica, sendo uma opção viável, capaz de gerar benefícios similares ao da fisioterapia convencional.

Antibiotics have a very important role in fighting bacterial infections in the body. However, the results given so far have not been optimal in overcoming the problem of bacterial infection. An alternative solution is to develop and study plants that have medicinal potential, for example thistle leaves (Calotrophis gigantean). The purpose of this study was to determine the antibacterial activity of thistle leaf extract against Escherichia coli and Staphylococcus aureus. This research is a laboratory-scale experimental research that is to test the activity of thistle leaf extract against Escherichia coli and Staphylococcus aureus including sample identification, extraction, activity testing by observing the inhibition zone of the two tested bacteria. Based on the results of the study stated that the ethanol extract of 70% Widuri leaves (Calotrophis gigantea) had antibacterial activity and could inhibit the growth of Escherichia coli and Staphylococcus aureus bacteria. The active compounds that are thought to have antibacterial properties in the ethanol extract of Widuri leaves (Calotrophis gigantea) are flavonoids, alkaloids and terpenoids.

Idiopathic scoliosis. Mechanisms of development
Authors: Viktorovich Late Serdyuk Valentyn , Valentinovich Serdiuk Oleksandr , Tishkin Grigory 
Published: November 2021

Objective: One of the most complicated problems of Orthopaedics is the treatment of scoliosis. More than 90% of cases are attributable to Idiopathic deformation, the cause of which is unknown. We investigated the cause of pathogenesis of this disorder.
Methods: At our institution more than 6900 patients aged 1-89 years have undergone inpatient and outpatient treatment in connection with spinal pain syndrome and different neurological disorders associated with idiopathic scoliosis. This study was undertaken between February 1996 and February 2010. All patients had a clinical, radiography and laboratory examinations.
Results: The 29.6% of patients were aged 31-50 years old. 60% were men and 40% were women. While examining patients with scoliosis deformation, we noted symptoms of body asymmetry i.e. different volumes of the right and left halves of face body and limbs. These features were typical for all patients irrespective of sex, age, and ethnic origin. 83,2% of patients had underdevelopment of the left part of the body, and only 16,8% of the right side. Analysis of published work in anatomy, physiology, neurophysiology, vertebrology, done simultaneously with analysis of the clinical material, allowed us to make some conclusions.
Conclusions: First asymmetrical structure of the human body is based on laws of nature and is linked with difference of sizes of brain’s hemispheres, particularly of the right and left gyrus centralis anterior which controls the muscle’s function and our movements. Second asymmetrical tension of Erector spinae muscles, leads to inclination of the pelvis on a side of weak muscles; thus initiating development of the lateral spine curves. Since such a situation is typical for all people, this deformation is known as functional scoliosis. Third, further development of the bodies of vertebrae, their arches, processes, intervertebral discs, ligaments, and other anatomical elements in position of the deviation leads to one sided underdevelopment of these structures. As a result the areas of instability appear in each segment of spine ( neck, chest, lumbar and sacral areas ). Fourth, the muscles in a growing body misbalance and on the ground of rotating movement, start rotatory dislocation of vertebrae in zones of instability in all parts of the spine. As a result torsion of the deformed wedge-shaped vertebrae leads to formation of the structural scoliosis. The rotation of the vertebrae, described above, does not depend on sex, age and ethnic origin of the patient and has a character of the natural development. Thus from our point of view, the term idiopathic scoliosis, must be changed to spinal muscle asymmetrical deformation of a reflex origin. Understanding of this rotation allowed us to establish an effective non-surgical method of treatment of scoliosis and spinal pain syndrome in patients of all ages.
Probing the Wind Component of Radio Emission in Luminous High-redshift Quasars

Published: November 2021

Abstract
We discuss a probe of the contribution of wind-related shocks to the radio emission in otherwise radio-quiet quasars. Given (1) the nonlinear correlation between UV and X-ray luminosity in quasars, (2) that such a correlation leads to higher likelihood of radiation-line-driven winds in more luminous quasars, and (3) that luminous quasars are more abundant at high redshift, deep radio observations of high-redshift quasars are needed to probe potential contributions from accretion disk winds. We target a sample of 50 z ≃ 1.65 color-selected quasars that span the range of expected accretion disk wind properties as traced by broad C iv emission. 3 GHz observations with the Very Large Array to an rms of ≈10 μJy beam−1 probe to star formation rates of ∼400 M
⊙ yr−1, leading to 22 detections. Supplementing these pointed observations are survey data of 388 sources from the LOFAR Two-meter Sky Survey Data Release 1 that reach comparable depth (for a typical radio spectral index), where 123 sources are detected. These combined observations reveal a radio detection fraction that is a nonlinear function of C iv emission-line properties and suggest that the data may require multiple origins of radio emission in radio-quiet quasars. We find evidence for radio emission from weak jets or coronae in radio-quiet quasars with low Eddington ratios, with either (or both) star formation and accretion disk winds playing an important role in optically luminous quasars and correlated with increasing Eddington ratio. Additional pointed radio observations are needed to fully establish the nature of radio emission in radio-quiet quasars.
Fragmenting Active Asteroid 331P/Gibbs
Authors: Jewitt David , Li Jing , Kim Yoonyoung 
Published: November 2021

Abstract
We describe active asteroid 331P/Gibbs (2012 F5) using archival Hubble Space Telescope (HST) data taken between 2015 and 2018. 331P is an outer main belt active asteroid with a long-lived debris trail that formed in 2011. Embedded in the debris trail we identify 19 fragments with radii between 0.04 and 0.11 km (albedo 0.05 assumed) containing about 1% of the mass of the primary nucleus. The largest shows a photometric range (∼1.5 mag), a V-shaped minimum, and a two-peaked lightcurve period near 9 hr, consistent with a symmetric contact binary. Less convincing explanations are that 331P-A is a monolithic, elongated splinter or that its surface shows hemispheric 4:1 albedo variations. The debris trail is composed of centimeter-sized and larger particles ejected with characteristic 10 cm s−1 speeds following a size distribution with index q = 3.7 ± 0.1 to 4.1 ± 0.2. The HST data show that earlier, ground-based measurements of the nucleus were contaminated by near-nucleus debris, which cleared by 2015. We find that the primary nucleus has effective radius 0.8 ± 0.1 km and is in rapid rotation (3.26 ± 0.01 hr), with a lightcurve range of 0.25 mag and a minimum density of 1600 kg m−3 if strengthless. The properties of 331P are consistent with (1) formation about 1.5 Myr ago by impact shattering of a precursor body, (2) spin-up by radiation torques to critical rotation, (3) ejection of about 1% of the nucleus mass in mid 2011 by rotational instability, and (4) subsequent evolution of the fragments and dispersal of the debris by radiation pressure.

Published: November 2021

Abstract
A detailed study of the BL Lacertae PKS 0903-57 has been done for the first time with 12 yr of Fermi Large Area Telescope data. We have identified two bright gamma-ray flares in 2018 and 2020. Many substructures were observed during multiple time binning of these flares. We performed a detailed temporal and spectral study on all the substructures separately. A single-zone emission model is used for time-dependent leptonic modeling of the multiwavelength spectral energy distributions. Our estimated values of variability timescale, magnetic field in the emission region, and the jet power obtained from leptonic modeling of PKS 0903-57 are presented in this work. Currently, we have a minimal number of observations in X-rays and other bands. Hence, further simultaneous multiwavelength monitoring of this source is required to have a better understanding of the physical processes occurring in the jet of the blazar PKS 0903-57.

We calculate directly determined values for effective temperature (T
eff) and radius (R) for 191 giant stars based upon high-resolution angular size measurements from optical interferometry at the Palomar Testbed Interferometer. Narrow- to wideband photometry data for the giants are used to establish bolometric fluxes and luminosities through spectral energy distribution fitting, which allows for homogeneously establishing an assessment of spectral type and dereddened V

0 = {1.9, 6.5} range, median T
eff uncertainties in the fit of effective temperature versus color are found to be less than 50 K; over this range, T
