Increasing attention has been paid to the potential probiotic effects of Latilactobacillus sakei. To explore the genetic diversity of L. sakei, 14 strains isolated from different niches (feces, fermented kimchi, and meat products) and 54 published strains were compared and analyzed. The results showed that the average genome size and GC content of L. sakei were 1.98 Mb and 41.22%, respectively. Its core genome mainly encodes translation and transcription, amino acid synthesis, glucose metabolism, and defense functions. L. sakei has open pan-genomic characteristics, and its pan-gene curve shows an upward trend. The genetic diversity of L. sakei is mainly reflected in carbohydrate utilization, antibiotic tolerance, and immune/competition-related factors, such as clustering regular interval short palindromic repeat sequence (CRISPR)–Cas. The CRISPR system is mainly IIA type, and a few are IIC types. This work provides a basis for the study of this species.

Gula aren dengan dosis 200 mg/kg BB dan 400 mg/kg BB diberikan pada tikus putih yang kemudian diinduksi CCl4 1,5 ml/kg BB. Penelitian ini bertujuan untuk melihat kadar enzim antioksidan yaitu SOD dan GPx setelah diinduksi CCl4 serta kerusakan yang ditimbulkan oleh CCl4 lewat pengukuran kadar MDA. Hasil penelitian menunjukkan bahwa kadar SOD dan GPX pada tikus kontrol negatif berbeda dengan kadar SOD dan GPx pada tikus yang diberikan gula aren. Kadar enzim antioksidan pada tikus yang diberikan gula aren hampir sama dengan tikus normal (kelompok yang tidak diinduksi CCl4). Hal tersebut berhubungan dengan kadar MDA dimana pada tikus kelompok kontrol negatif menunjukkan kadar MDA yang tinggi sedangkan pada tikus normal dan tikus yang diberikan gula aren menunjukkan kadar MDA rendah yang artinya bahwa enzim antioksidan pada tikus normal dan tikus yang diberikan gula aren mengadakan peredaman terhadap reaksi oksidasi yang disebabkan oleh CCl4 sehingga peroksidasi lipid yang terjadi sangat kecil.ABSTRACT Palm sugar with a dose of 200 mg/kg BB and 400 mg/kg BB given to white rats which then induced CCl4 1.5 ml/kg BB. This study aims to look at the levels of antioxidant enzymes namely SOD and GPx after CCl4 induction and the damage caused by CCl4 through MDA level measurements. The results showed that SOD and GPX levels in negative control rats differed from SOD and GPx levels in rats given palm sugar. The levels of antioxidant enzymes in rats given palm sugar were almost the same as those in normal rats (CCl4-induced groups). This is related to MDA levels where in the negative control group rats showed high MDA levels while in normal rats and group rats given palm sugar showed low MDA levels which means that the antioxidant enzymes in normal rats and group rats given palm sugar made damping against oxidation reactions which is caused by CCl4 so that the lipid peroxidation that occurs is very small.

Published: July 2021

Abstract
We investigate characteristic fluctuations in multi-quantum well (MQW)-based waveguides whose absorption spectrum experimentally changes as a ∼5 nm blue shift when dielectric passivation layers are employed. We theoretically show that the blue shift corresponds to a ∼0.03% compressive strain in the MQW resulting in a group refractive index change (Δn

g
) of ∼−0.01. The estimated Δn

g
agrees with an experimentally obtained free spectral range of transmittance of an asymmetric Mach–Zehnder interferometer composed of the MQW structure. The results indicate that our theoretical estimation is an efficient way to evaluate the MQW-based waveguide performance with an external stress.

Análise da Dinâmica Temporal da Paisagem do Município Amazônico de São Geraldo do Araguaia-PA, Brasil
Authors: Silva Samuel Santos , Mendes Maurício Ferreira , Perlandim Ramos Alexander Webber 
Published: July 2021

Este trabalho tem como objetivo analisar a dinâmica da paisagem e mensurar a pressão antrópica sobre os componentes ambientais do município de São Geraldo do Araguaia – Pará. Foram utilizados dados de mapeamentos de cobertura vegetal e usos da terra do projeto MapBiomas (1988-2018). A mensuração da pressão antrópica foi realizada por meio da aplicação do Índice de Transformação Antrópica (ITA) com o intuito de verificar a paisagem em sua totalidade e de forma isolada, considerando as áreas que possuem proteção ambiental. No período analisado, ocorreram diversas modificações na paisagem natural no município. O resultado do ITA evidenciou que essas modificações têm gerado pressão sobre os componentes da paisagem e, consequentemente, uma piora no estado de conservação ambiental da municipalidade. Pode-se verificar que as áreas com proteção ambiental, apesar de apresentarem antropização, foram de suma importância para conter o desmatamento, amenizando a pressão sobre os componentes naturais.
Intolerance of uncertainty is associated with heightened responding in the prefrontal cortex during cue-signalled uncertainty of threat

Published: July 2021

AbstractHeightened responding to uncertain threat is considered a hallmark of anxiety disorder pathology. We sought to determine whether individual differences in self-reported intolerance of uncertainty (IU), a key transdiagnostic dimension in anxiety-related pathology, underlies differential recruitment of neural circuitry during cue-signalled uncertainty of threat (n = 42). In an instructed threat of shock task, cues signalled uncertain threat of shock (50%) or certain safety from shock. Ratings of arousal and valence, skin conductance response (SCR), and functional magnetic resonance imaging were acquired. Overall, participants displayed greater ratings of arousal and negative valence, SCR, and amygdala activation to uncertain threat versus safe cues. IU was not associated with greater arousal ratings, SCR, or amygdala activation to uncertain threat versus safe cues. However, we found that high IU was associated with greater ratings of negative valence and greater activity in the medial prefrontal cortex and dorsomedial rostral prefrontal cortex to uncertain threat versus safe cues. These findings suggest that during cue-signalled uncertainty of threat, individuals high in IU rate uncertain threat as aversive and engage prefrontal cortical regions known to be involved in safety-signalling and conscious threat appraisal. Taken together, these findings highlight the potential of IU in modulating safety-signalling and conscious appraisal mechanisms in situations with cue-signalled uncertainty of threat, which may be relevant to models of anxiety-related pathology.
The 3.3 μm Infrared Emission Feature: Observational and Laboratory Constraints on Its Carrier
Authors: Tokunaga Alan T. , Bernstein Lawrence S. 
Published: July 2021

Abstract
We examine the self-consistency of laboratory and observational data for potential carriers of the 3.3 μm infrared emission feature (IEF), a member of the ubiquitous family of strong interstellar IEFs at 3.3, 3.4, 6.2, 7.7, 8.6, 11.2, and 12.7 μm. Previous studies have shown that most Galactic sources (reflection nebulae, H ii regions, and planetary nebulae) show 3.3 μm IEFs displaying similar central wavelengths, FWHM, and profiles. Our study is focused on the band profile designated as Class A, the most prevalent of four classes of observed band profiles. In contrast to the observations, laboratory spectra for gas phase polycyclic aromatic hydrocarbons (PAHs), the widely assumed carriers of the IEFs, display central wavelength shifts, widths, and profiles that vary with temperature and PAH size. We present an extrapolation of the laboratory band shifts and widths for smaller PAHs (≤32 carbon atoms) to the larger PAHs (>50 carbon atoms) that are thought to be the IEF carriers. The extrapolation leads to tight constraints on the sizes of the putative PAH carriers. Reconciling the observations with the implications of the laboratory spectra pose a significant challenge to the PAH and other IEF carrier hypotheses.

Abstract
Two extremely red main-belt asteroids, 203 Pompeja and 269 Justitia, were identified from combined visible and near-infrared spectroscopic observations collected at the Infra-red Telescope Facility (IRTF) and Seoul National University Astronomical Observatory (SAO). These two asteroids have a redder spectral slope than any other D-type body, which are the reddest objects in the asteroid belt, and similar to RR and IR-class objects found in the outer Solar System among trans-Neptunian objects (TNOs) and Centaurs. Spectroscopic results suggest the presence of complex organic materials on the surface layer of these asteroids, implying that they could have formed in the vicinity of Neptune and been transplanted to the main belt region during a phase of planetary migration. 203 Pompeja is the only very red asteroid known so far among the ∼250 bodies with diameter larger than 110 km (i.e., presumably structurally intact) found in the asteroid belt. These discoveries provide more evidence that the main asteroid belt hosts a population of bodies that were formed in the outskirts of the Solar System.

Abstract
During 2020 April and May, SGR J1935+2154 emitted hundreds of short bursts and became one of the most prolific transient magnetars. At the onset of the active bursting period, a 130 s burst “forest,” which included some bursts with peculiar time profiles, were observed with the Fermi/Gamma-ray Burst Monitor (GBM). In this Letter, we present the results of time-resolved spectral analysis of this burst “forest” episode, which occurred on 2020 April 27. We identify thermal spectral components prevalent during the entire 130 s episode; high-energy maxima appear during the photon flux peaks, which are modulated by the spin period of the source. Moreover, the evolution of the ν
F

ν
spectral hardness (represented by E
peak or blackbody temperature) within the lightcurve peaks is anti-correlated with the pulse phases extrapolated from the pulsation observed within the persistent soft X-ray emission of the source six hours later. Throughout the episode, the emitting area of the high-energy (hotter) component is 1–2 orders of magnitude smaller than that for the low-energy component. We interpret this with a geometrical viewing angle scenario, inferring that the high-energy component likely originates from a low-altitude hotspot located within closed toroidal magnetic field lines.
Biovera-Epi: A new database on species diversity, community composition, and leaf functional traits of vascular epiphytes along an elevational gradient in Mexico

Published: July 2021

This data paper describes a new, comprehensive database (BIOVERA-Epi) on species distributions and leaf functional traits of vascular epiphytes, a poorly studied plant group, along gradients of elevation and forest-use intensity in the central part of Veracruz State, Mexico. The distribution data includes frequencies of 271 vascular epiphyte species belonging to 92 genera and 23 families across 120 20 m × 20 m forest plots at eight study sites along an elevational gradient from sea level to 3500 m a.s.l. In addition, BIOVERA-Epi provides information on 1595 measurements of nine morphological and chemical leaf traits from 474 individuals and 102 species. For morphological leaf traits, we provide data on each sampled leaf. For chemical leaf traits, we provide data at the species level per site and land-use type. We also provide complementary information for each of the sampled plots and host trees. BIOVERA-Epi contributes to an emerging body of synthetic epiphytes studies combining functional traits and community composition.
BIOVERA-Epi includes data on species frequency and leaf traits from 120 forest plots distributed along an elevational gradient including six different forest types and three levels of forest-use intensity. It will expand the breadth of studies on epiphyte diversity, conservation, and functional plant ecology in the Neotropics and will contribute to future synthetic studies on the ecology and diversity of tropical epiphyte assemblages.
Social Media and Retinal Detachment: Perspectives of Providers and Patients on Instagram
Authors: Alsoudi Amer F. , Rayess Nadim , Khan Suleman , Koo Euna , Rahimy Ehsan 
Published: July 2021

BACKGROUND AND OBJECTIVE:
To evaluate the social media interactions of patients who experience retinal detachment and/or repair and how ophthalmic medical providers utilize social media.

PATIENTS AND METHODS:
A cross-sectional study of public posts on Instagram was performed from September 2019 to January 2020, with filtering based on the following hashtags: #retinaldetachment, #detachedretina, #retinaldetachmentsurgery, and #scleralbuckle. A categorical classification system was used for each Instagram post to review descriptive variables.

RESULTS:
Of the 1,797 Instagram posts analyzed, 697 (39%) were made by patients, of which 395 (57%) were positive in tone and 599 (86%) were in the postoperative period. Posts by ophthalmologists were most commonly centered on colleague education (446, 81%).

CONCLUSIONS:
The majority of Instagram posts by patients were of a positive tone reflecting primarily on activities of daily living and rehabilitations. Retina specialists should consider providing more social media content directed toward patients, particularly regarding their rehabilitation course following retinal detachment repair.
