This study investigates the efficacy and mechanisms of Kuanxiong Aerosol (KXA) on coronary microvascular dysfunction (CMD) in rats. Thirty-two Sprague-Dawley rats were divided into control, model, KXA, and nicorandil groups, receiving respective treatments for three weeks. The CMD model was established byinjecting lauric acid into the left ventricle. Compared to the model group, the KXA group showed significant reductions in serum CK-MB, LDH, cTnI, ET-1, TNF-α, IL-6, MDA, and ROS (p<0.01) and increased NO and SOD levels (p<0.01). KXA mitigated apoptosis and ameliorated CMD-associated pathological alterations. Pretreatment with KXA improves endothelial function and microvascular structure by counteracting inflammation, oxidative stress, and apoptosis, thereby improving CMD.

Authors: Gaitan Monroy Juan Pablo
Published: September 2024

La investigación estimó la captura de 20 zarigüeyas, sin importar rango de edad o sexo, situadas en el parque Zoológico Nacional La Aurora en Ciudad de Guatemala. El objetivo fue determinar la presencia de Mycoplasma sp. en las mismas, a través del método de frotis sanguíneo.   Investigaciones recientes han destacado la importancia de los micoplasmas hemotrópicos como patógenos zoonóticos emergentes y subrayado la necesidad de una detección y diagnóstico precisos, así como de una mayor comprensión de su epidemiología y su impacto en la salud de los animales y posiblemente de los seres humanos. Así como han destacado la importancia de investigar el papel de los vectores en la transmisión de estas infecciones en la fauna silvestre debido a que esta enfermedad ha estado asociada a una alta morbilidad y baja mortalidad en mamíferos de zoológicos en  todo  el  mundo. Se registraron un total de 8 casos positivos a la prueba de frotis sanguíneo, de los cuales, 5 fueron hembras (62,00%) y 3 machos (37,05%). Se concluye que la microscopia debe ser acompañada de otras pruebas con el fin de obtener diagnósticos más certeros y conocer la especie de Mycoplasma que afecta a los huéspedes.

Authors: Wahyuni Fitri Ilma , Andriani Sri
Published: September 2024

This study investigates the effect of reduction tax rates in Indonesia and other factors that may impact tax aggressiveness. This study employs multiple linear regression analysis, using E-Views 12 as analytical software. A sample of fourteen real estate and property companies listed on the Indonesia Stock Exchange (IDX) for 2017 to 2023 was identified through purposive sampling. This study relies on secondary data derived from the company's financial statements. The results showed that the reduction in tax rates and the presence of independent commissioners did not significantly affect tax aggressiveness. In contrast, institutional ownership and profitability factors positively correlate with tax aggressiveness, while leverage shows a negative correlation. It is expected that the results of this study will contribute to the development of taxation policies for companies in Indonesia, aiming to reduce aggressive taxation practices and assist companies in their tax-related decision-making framework.

REVIEW : OF SUPERDISINTEGRANT INGREDIENTS IN FAST DISINTEGRANT TABLET TABLET PREPARATIONS
Authors: Fahmansyah Lingga Pratama , Agus S  , Suparman
Published: September 2024

This study aimed to evaluate the potential of synthetic and natural disintegrating agents in fast-disintegrating tablet (FDT) formulations. The methodology used includes a comprehensive literature review on the definition, characteristics, working mechanisms, and applications of super disintegrants in the manufacture of FDTs. The results of the study showed that super disintegrants play an important role in facilitating rapid disintegration of tablets. Synthetic super disintegrants such as crospovidone, croscarmellose sodium, and sodium starch glycolate have the advantage of lower concentrations and better intragranular effectiveness. On the other hand, natural superdisintegrants such as mucilages, gums, and polysaccharides from plants have easy availability, affordable prices, non-toxic properties, and biologically acceptable characteristics. In conclusion, the selection of an appropriate super disintegrant, whether synthetic or natural, is a key factor in effective FDT formulation and providing rapid disintegration. The combination of using super disintegrants at the granulation stage (intragranular) and before compression (extragranular) can produce better performance compared to a single method.

Building Our Families: Navigating Barriers in 2SLGBTQ+ Family Building Through Doula Supports
Authors: Zisman Laine Halpern
Published: September 2024

Queer and transgender individuals often encounter barriers when attempting to build their families, Beginning by identifying barriers that 2SLGBTQ+ people face in their fertility and reproductive journeys -- including limited access to information, inadequate diversity in donor gametes, and minority stress --  this article looks to the role of doulas in mitigating challenges by providing critical and tailored support, educational resources, and support and advocacy in navigating medical systems. Using a reproductive justice and intersectional framework, the article highlights the need for inclusive care practices that address the historical and ongoing exclusion of marginalized 2SLGBTQ+ communities. It underscores the importance of improved training for healthcare providers and systemic changes to ensure equitable family-building experiences for 2SLGBTQ+ individuals. By integrating community supports and peer advocacy, the article proposes strategies to enhance both the physical and mental health outcomes of 2SLGBTQ+ intended parents and their families. It calls for a comprehensive approach that combines professional training, systemic reform, and community-based initiatives to create a more inclusive and supportive environment for family-building among 2SLGBTQ+ individuals.
All we want is, free, safe, legal, local abortion access for everyone who needs it: An examination of the Northern Ireland decriminalisation of abortion campaign
Authors: Campbell Emma
Published: September 2024

The decriminalisation of abortion in Northern Ireland in 2019 was politically complex. This paper presents an overview from my perspective as the co-convenor of Alliance for Choice (AfC), the primary abortion activist group in the North, focusing on the socio-political background, then analysis via key themes. It considers abortion law in Northern Ireland as British colonialism in Ireland; it then follows the recent political crisis in the British government that offered abortion activists an unprecedented opportunity for restitution via decriminalisation. There is an examination of the influence of SisterSong’s work, which informed Alliance for Choice’s (AfC) campaign for decriminalisation (Bloomer & Pierson 2020). The article critically examines multiple barriers to abortion faced by people in Northern Ireland, where navigating complex abortion health systems for access to abortion care leaves too many behind. Finally, it illustrates how the needs of abortion seekers are better addressed by focusing on decriminalisation. It concludes by identifying how this can inform reproductive justice campaigns elsewhere and recognises the intersectional work that remains to be done. Together it illustrates how in Northern Ireland, multiple layers of campaigning and political change were utilised to bring forth significantly greater bodily autonomy within a human rights and grassroots framework.

Examina a história, os impulsionadores e as perspectivas das negociações de financiamento para o desenvolvimento (FfD) nas Nações Unidas (ONU), com foco no engajamento do Brasil. Desde a adoção da Agenda 2030 para o Desenvolvimento Sustentável e da Agenda de Ação de Addis Abeba em 2015, as discussões de FfD enfrentam desafios em meio a uma mudança de paradigma na cooperação internacional. Apesar do estabelecimento de mecanismos como o Fórum do ECOSOC sobre Acompanhamento do Financiamento para o Desenvolvimento e o Grupo de Trabalho Interinstitucional sobre FfD, as discussões baseadas em consenso têm lutado para cumprir compromissos, especialmente em relação à assistência oficial para o desenvolvimento (ODA) e responsabilidades diferenciadas entre países desenvolvidos e em desenvolvimento. Tendências recentes, incluindo a crise da ODA e debates sobre cooperação tributária, destacam divisões na cooperação internacional. O Brasil, como membro do G77 + China e com laços com a OCDE, desempenha um papel crucial na mediação de discussões e na promoção das aspirações dos países em desenvolvimento. Apesar de contextos polarizados, a convergência está surgindo em áreas como o envolvimento do setor privado e as práticas de cooperação para o desenvolvimento. O papel do setor privado no FfD evoluiu significativamente, com o Brasil facilitando a primeira resolução da Assembleia Geral da ONU sobre a promoção de investimentos para o desenvolvimento sustentável em 2019.

Liquid Biopsy in Cancer Diagnosis-Treatment Methodology and Applications
Authors: Mitra Sanchari , Fatima Khatoon Hena
Published: September 2024

The comprehensive review of liquid biopsy as a cutting-edge, non-invasive technique for cancer detection, diagnosis, and monitoring may be found in the document “Liquid Biopsy in Cancer Diagnosis – Treatment Methodology and Applications.” Via liquid biopsy, tumor-related indicators present in physiological fluids such as blood, urine, and saliva are examined, including exosomes, circulating tumor cells (CTCs), and circulating tumor DNA (ctDNA). Liquid biopsy enables regular, real-time sampling of tumor dynamics, in contrast to standard tissue biopsies, which are invasive and restricted to particular tumor regions. This renders it a potent instrument for the identification of cancer mutations and the tracking of tumor progression, particularly in cases of metastatic or elusive cancers. Technological developments like digital droplet PCR (ddPCR) and next-generation sequencing (NGS) have greatly improved the sensitivity and precision of ctDNA detection, making it possible to identify unusualexceptionally rare genetic mutations. This enhances the efficacy of tailored cancer treatment and monitoring. The genetic heterogeneity of cancers is captured by liquid biopsies, providing information on several tumor subclones that may be missed by traditional biopsies. The document also describes the use of different body fluids for different forms of cancer, such as head and neck and urological tumors, such as saliva, urine, and blood. Blood is the most often utilized medium for tracking genetic changes due to its ease of accessibility. Saliva and urine are useful in the detection of head and neck malignancies and bladder cancer, respectively. Liquid biopsy has several advantages, but it also has drawbacks, such as the requirement for standardized procedures, high prices, and differences in sensitivity and specificity between platforms.In order to overcome these obstacles and integrate liquid biopsy into standard clinical practice, the paper emphasizes the significance of more research and development. This will improve patient outcomes, early cancer detection, and personalized treatment.

Peculiarities of online user’s content search in the context of inbound marketing
Authors: Davidavičius Sigitas
Published: September 2024

The article addresses the issue of the distribution of users browsing the internet for content in a specific format through alternative content delivery channels in the context of inbound marketing. The problem being addressed is part of a broader problem with the formation of traffic to an organization’s website. The theoretical part of the work presents the concept of inbound marketing and analyzes the theoretical aspects of its tactical activities, such as content marketing, search engine marketing, and social media marketing. Based on the theoretical research, the scientific hypothesis is formulated – there are links between the desired content format and the choice of content search and consumption channel. The research methodology consists of data collection by survey method and hypothesis testing using Cochran’s Q test. Empirical research has shown links between the content format sought and the channels for searching and consuming content. Although in almost all cases the search for video and audio content is dominated by search engines, evaluating other content delivery channels reveals a significant specialty of users’ web browsing.
Brightening and Fading in the Youngest Galactic Supernova Remnant G1.9+0.3: 13 Years of Monitoring with the Chandra X-Ray Observatory

Published: September 2024

We report 13 years of Chandra monitoring of the youngest Galactic supernova remnant G1.9+0.3, the only remnant known to be increasing in brightness. We confirm the spatially integrated rate of flux increase of (1.2 ± 0.2)% yr−1 (1–7 keV), but find large spatial variations, from −3% yr−1 to +7% yr−1, over length scales as small as 10″ or smaller. We observe relatively little change in spectral slope, though one region shows significant hardening as it brightens by 1% yr−1. Such rates of change can be accommodated by any of several explanations, including steady blast-wave evolution, expansion or compression of discrete plasma blobs, magnetic turbulence, or variations in magnetic-field aspect angle. Our results do not constrain the mean magnetic-field strength, but a self-consistent picture can be produced in which the maximum particle energies are limited by the remnant age (applying both to electrons and to ions) to about 20 TeV, and the remnant-averaged magnetic-field strength is about 30 μG. The deceleration parameter m (average shock radius varying as t

m
) is about 0.7, consistent with estimates from overall expansion dynamics and confirming an explosion date of about 1900 CE. Shock-efficiency factors ϵ

e
and ϵ

B
(fractions of shock energy in relativistic electrons and magnetic field) are 0.003 and 0.0002 in this picture. However, the large range of rates of brightness change indicates that such a global model is oversimplified. Temporal variations of photon index, expected to be small but measurable with longer time baselines, can discriminate among possible models.

We present the discovery of a unique Lyman-continuum (LyC) emitter at z = 3.088. The LyC emission was detected using the Hubble Space Telescope WFC3/UVIS F336W filter, covering a rest-frame wavelength range of 760–900 Å. The peak signal-to-noise ratio of LyC emission is 3.9 in an r = 0.″24 aperture and is spatially offset by 0.″29 ± 0.″04 (∼2.2 ± 0.3 kpc) from the peak of rest-UV emission (F606W). By combining imaging and spectroscopic data from the James Webb Space Telescope (JWST) JADES, FRESCO, and JEMS surveys, along with VLT/MUSE data from the MXDF survey, we estimate that the probability of random alignment with an interloper galaxy causing the LyC emission is less than 6 × 10−5. The interstellar medium (ISM) conditions in the galaxy are similar to those in other LyC emitters at high redshift (

, O32 = 0.63 ± 0.03), although the single-peaked Lyα profile and lack of rest-UV emission lines suggest an optically thick ISM. Our observations indicate that LyC photons are leaking through a narrow cone of optically thin neutral ISM, most likely created by a past merger (as evidenced by medium-band F210M and F182M images). Using the constraints on escape fraction from individual leakers and a simple model, we estimate that the opening half-angle of ionization cones can be as small as 16° (2% ionized fraction) to reproduce some of the theoretical constraints on the average escape fraction for galaxies. The narrow opening angle required can explain the low number density of confirmed LyC leakers.
Why Could a Newborn Active Region Produce Coronal Mass Ejections?
Authors: Yang Hanzhao , Liu Lijuan
Published: September 2024

Solar active regions (ARs) are the main sources of flares and coronal mass ejections (CMEs). NOAA AR 12089, which emerged on 2014 June 10, produced two C-class flares accompanied by CMEs within 5 hr after its emergence. When producing the two eruptive flares, the total unsigned magnetic flux (ΦAR) and magnetic free energy (E

f
) of the AR are much smaller than the common CME-producing ARs. Why can this extremely small AR produce eruptive flares so early? We compare the AR magnetic environment for the eruptive flares to that for the largest confined flare from the AR. In addition to the ΦAR and E

f
, we calculate the ratio between the mean characteristic twist parameter (α
FPIL) within the flaring polarity inversion line (FPIL) region and ΦAR, a parameter considering both background magnetic field constraint and nonpotentiality of the core region, for the three flares. We find higher α
FPIL/ΦAR values during the eruptive flares than during the confined flare. Furthermore, we compute the decay index along the polarity inversion line, revealing values of 1.69, 3.45, and 0.98 before the two eruptive and the confined flares, respectively. Finally, nonlinear force-free field extrapolation indicates that a flux rope was repeatedly formed along the FPIL before eruptive flares, which ejected out and produced CMEs. No flux rope was found before the confined flare. Our research suggests that even a newly emerged, extremely small AR can produce eruptive flares if it has sufficiently weak background field constraint and strong nonpotentiality in the core region.
A Precessing Stellar Disk Model for Superorbital Modulations of the Gamma-Ray Binary LS I+61° 303

Gamma-ray binary LS I+61° 303 consists of a neutron star orbiting around a Be star with a period of P

as seen in nearly all wavelengths. The origin of this superorbital modulation is still not well understood. Under the pulsar wind–stellar outflow interaction scenario, we propose that the superorbital modulations of LS I+61° 303 could be caused by the precession of the Be disk. Assuming X-rays arise from synchrotron radiation of the intrabinary shock, we develop an analytical model to calculate expected flux modulations over the orbital and superorbital phases. The asymmetric two-peak profiles in orbital light curves and sinusoidal-like long-term modulations are reproduced under the precessing disk scenario. The observed orbital phase drifting of the X-ray peak and our fitting of long-term X-ray data indicate that the neutron star is likely orbiting around the star with a small eccentricity and periastron phase around Φp ∼ 0.6. We compare the Corbet diagrams of LS I+61° 303 with other Be/X-ray binaries, and the linear correlation in the

The Dustiest Galactic S Stars: Mid-infrared Spectra from SOFIA/FORCAST
Authors: Kraemer Kathleen E. , Sloan G. C. , Ramirez Ramses M.
Published: September 2024

We present spectra of 12 of the reddest, and hence dustiest, S stars in the Milky Way, observed with the FORCAST grisms on SOFIA. S stars are asymptotic giant branch (AGB) stars with C/O ∼ 1, so their molecular and dust chemistries are dominated by neither O nor C, often leading to atypical spectral features from their molecules and dust grains. All of the stars in our sample have strong dust emission features at 10–11 μm, but the shape of the feature in most of the stars differs from the shapes commonly observed in either oxygen-rich or carbon-rich AGB stars. Two stars also show the 13 μm feature associated with crystalline alumina. Two have a water absorption band at ∼6.5–7.5 μm, and a third has a tentative detection, but only one of these three has the more common SiO absorption band at 7.5 μm. Three others show a red 6.3 μm emission feature from complex hydrocarbons consistent with “Class C” objects, and in a fourth it appears at 6.37 μm, redder than even the standard Class C hydrocarbon feature. Class C spectra typically indicate complex hydrocarbons that have been less processed by UV radiation, resulting in more aliphatic bonds relative to aromatic bonds. None of the S stars show a strong 11.3 μm hydrocarbon feature, which is also consistent with the presence of aliphatic hydrocarbons.
