Authors: Putra Abrardy Firlana , Kusnadi Kusnadi
Published: December 2024

This research focuses on analyzing the implementation “of Total Productive Maintenance (TPM)” at PT. VPRK “by” utilizing “Overall Equipment Effectiveness (OEE) as an indicator” to assess “the” performance of grinding machines at PT. VPRK. The aim of the research is to evaluate the effectiveness and efficiency of the machine by identifying inhibiting factors that influence the performance of the grinding machine. The TPM method is applied to increase availability, quality and overall machine performance. OEE is used as a critical measuring tool to assess productivity and operational efficiency. The research results show that the OEE value of grinding machines in the January 2023 period is 79.78%. This value is not in accordance with the world-class OEE value standard, which is 85%. The biggest factor that influences the low OEE value is because the machine downtime is quite high, which affects the machine availability value so the machine availability value is 81.16%.

Published: December 2024

In the present work we report Synthesis, Computational ADME study, Pharmacological evaluation and In-vitro hydrolysis study of new mutual prodrugs of N-(2,3-xylyl anthranillic acid) prepared with and without spacer using Dicyclohexylcarbodiimide (DCC) as coupling agent. The structures of mutual prodrugs formed were confirmed by advanced spectroscopic techniques. The title compounds were tested for analgesic activity by Eddy’s hot plate and tail-flick method; for anti-inflammatory activity by carrageenan induced rat paw edema method and for ulcerogenicity and acute oral toxicity. Title compounds exhibited promising analgesic and anti-inflammatory activity. The compounds were found to be devoid of ulcerogenicity at the test dose level and presented significant values of the ADME properties studied, obeying Lipinski Rule of five violations, good oral absorption and lipophilicity. Hydrolysis studies revealed that the compounds were sufficiently stable at pH 1.2, indicating that no appreciable hydrolysis to the free acids might occur in the stomach. The amount of free drug released on hydrolysis in 80% human plasma (pH 7.4) was greater than that released in aqueous buffers, suggesting that the rate of hydrolysis of compounds in 80% human plasma was markedly accelerated compared with that in aqueous buffers.

Published: December 2024

BACKGROUND

Hepatocellular carcinoma (HCC) has been a pervasive malignancy throughout the world with elevated mortality. Efficient therapeutic targets are beneficial to treat and predict the disease. Currently, the exact molecular mechanisms leading to the progression of HCC are still unclear. Research has shown that the microRNA-142-3p level decreases in HCC, whereas bioinformatics analysis of the cancer genome atlas database shows the ASH1L expression increased among liver tumor tissues. In this paper, we will explore the effects and mechanisms of microRNA-142-3p and ASH1L affect the prognosis of HCC patients and HCC cell bioactivity, and the association between them.

AIM

To investigate the effects and mechanisms of microRNA-142-3p and ASH1L on the HCC cell bioactivity and prognosis of HCC patients.

METHODS

In this study, we grouped HCC patients according to their immunohistochemistry results of ASH1L with pathological tissues, and retrospectively analyzed the prognosis of HCC patients. Furthermore, explored the roles and mechanisms of microRNA-142-3p and ASH1L by cellular and animal experiments, which involved the following experimental methods: Immunohistochemical staining, western blot, quantitative real-time-polymerase chain reaction, flow cytometric analysis, tumor xenografts in nude mice, etc . The statistical methods involved in this study contained t -test, one-way analysis of variance, the χ 2 test, the Kaplan-Meier approach and the log-rank test.

RESULTS

In this study, we found that HCC patients with high expression of ASH1L possess a more recurrence rate as well as a decreased overall survival rate. ASH1L promotes the tumorigenicity of HCC and microRNA-142-3p exhibits reduced expression in HCC tissues and interacts with ASH1L through targeting the ASH1L 3′untranslated region. Furthermore, microRNA-142-3p promotes apoptosis and inhibits proliferation, invasion, and migration of HCC cell lines in vitro via ASH1L . For the exploration mechanism, we found ASH1L may promote an immunosuppressive microenvironment in HCC and ASH1L affects the expression of the cell junction protein zonula occludens-1, which is potentially relevant to the immune system.

CONCLUSION

Loss function of microRNA-142-3p induces cancer progression and immune evasion through upregulation of ASH1L in HCC. Both microRNA-142-3p and ASH1L can feature as new biomarker for HCC in the future.
Redefining endoluminal biliary drainage: Challenges and innovations in endosonography-guided techniques
Authors: Razpotnik Marcel
Published: December 2024

Endoscopic retrograde cholangiopancreatography is considered the gold standard for treating benign and malignant biliary obstructions. However, its use in complex biliary obstructions is limited. Over the past decades, therapeutic endosonography (EUS) and emerging technologies such as lumen-apposing metal stents have enabled endoscopic treatment of conditions previously requiring non-endoscopic or surgical approaches. Studies show that EUS-guided choledochoduodenostomy is a reliable alternative to endoscopic retrograde cholangiopancreatography in the treatment of distal malignant biliary obstructions and can be considered a primary drainage modality in centers with adequate expertise. For malignant hilar biliary obstructions, draining at least 50% of viable liver tissue often requires combining different modalities. The treatment strategy in these patients should be individualized, depending on the Bismuth classification, patient physical status, and intended systemic therapy. Due to the lack of evidence, general recommendations cannot be made for EUS-guided hepaticoduodenostomy or combined procedures with transhepatic bridging stents. These novel techniques should be limited to selected palliative cases where conventional methods have failed and conducted within clinical trials to generate evidence before broader application.
Transfer RNA-derived small RNA serves as potential non-invasive diagnostic marker and a novel therapeutic target for acute pancreatitis
Authors: Zhang Jing , Ou Chun-Lin
Published: December 2024

Transfer RNA (tRNA)-derived fragments, a new type of tRNA-derived small RNA (tsRNA), can be cleaved from tRNA by enzymes to regulate target gene expression at the transcriptional and translational levels. tsRNAs are not only degradation fragments but also have biological functions, including those in immune inflammation, metabolic disorders, and cell death. tsRNA dysregulation is closely associated with multiple diseases, including various cancers and acute pancreatitis (AP). AP is a common gastrointestinal disease, and its incidence increases annually. AP development is associated with tsRNAs, which regulate cell injury and induce inflammation, especially pyroptosis and ferroptosis. Notably, serum tRF36 has the potential to serve as a non-invasive diagnostic biomarker and leads to pancreatic acinar cell ferroptosis causing inflammation to promote AP. We show the characteristics of tsRNAs and their diagnostic value and function in AP, and discuss the potential opportunities and challenges of using tsRNAs in clinical applications and research.
Effect of cholesterol metabolism on hepatolithiasis
Authors: Zheng Lin , Ye Zi-Yu , Ma Jun-Ji
Published: December 2024

Surgical intervention is currently the primary treatment for hepatolithiasis; however, some patients still experience residual stones and high recurrence rates after surgery. Cholesterol metabolism seems to play an important role in hepatolithiasis pathogenesis. A high cholesterol diet is one of the significant reasons for the increasing incidence of hepatolithiasis. Therefore, regular diet and appropriate medical intervention are crucial measures to prevent hepatolithiasis and reduce recurrence rate after surgery. Reducing dietary cholesterol and drugs that increase cholesterol stone solubility are key therapeutic approaches in treating hepatolithiasis. This article discusses the cholesterol metabolic pathways related to the pathogenesis of hepatolithiasis, as well as food intake and targeted therapeutic drugs.
Gut-liver axis in sepsis-associated liver injury: Epidemiology, challenges and clinical practice
Authors: Moura Fabiana Andréa , Siqueira Aryana Isabelle de Almeida Neves
Published: December 2024

Although the liver has a remarkable regenerative capacity, sepsis-associated liver injury (SLI) is a complication often seen in intensive care units. Due to its role in immune and inflammatory regulation, the liver is particularly vulnerable during severe infections. Understanding the global prevalence, causes, and management of SLI is essential to improve outcomes and reduce healthcare costs. This paper aims to explore these factors, with an emphasis on identifying effective strategies for clinical management. Zhang et al ’s bibliometric analysis of 787 publications (745 original articles and 42 reviews, mostly in animal models) from 2000 to 2023 highlights the growing interest in SLI, focusing on oxidative stress, gut microbiota, and inflammatory processes. Key components such as nuclear factor-kappa B and the NOD-like receptor thermal protein domain associated protein 3 inflammasome pathway, along with their links to gut microbiota imbalance and oxidative stress, are crucial for understanding SLI pathogenesis. The gut-liver axis, particularly the role of intestinal permeability and bacterial translocation in liver inflammation, is emphasized. In this context, bacterial translocation is especially relevant for critically ill patients, as it can exacerbate liver inflammation. The findings underscore the need for integrated care in intensive care units, prioritizing gut health and careful antibiotic use to prevent dysbiosis. Despite extensive research, there remains a lack of clinical trials to validate therapeutic approaches. The abundance of experimental studies highlights potential therapeutic targets, stressing the need for high-quality randomized clinical trials to translate these findings into clinical practice.

One of the outstanding goals of the planetary science community is to measure the present-day atmospheric composition of planets and link this back to formation. As giant planets are formed by accreting gas, ices, and rocks, constraining the relative amounts of these components is critical to understand their formation and evolution. For most known planets, including the solar system giants, this is difficult as they reside in a temperature regime where only volatile elements (e.g., C, O) can be measured, while refractories (e.g., Fe, Ni) are condensed to deep layers of the atmosphere where they cannot be remotely probed. With temperatures allowing for even rock-forming elements to be in the gas phase, ultrahot Jupiter atmospheres provide a unique opportunity to simultaneously probe the volatile and refractory content of giant planets. Here, we directly measure and obtain bounded constraints on the abundances of volatile C and O as well as refractory Fe and Ni on the ultrahot giant exoplanet WASP-121b. We find that ice-forming elements are comparatively enriched relative to rock-forming elements, potentially indicating that WASP-121b formed in a volatile-rich environment much farther away from the star than where it is currently located. The simultaneous constraint of ice and rock elements in the atmosphere of WASP-121b provides insights into the composition of giant planets otherwise unattainable from solar system observations.

In total, we detect 44 6.0 GHz OH masers, 8 of which are new detections (one at 6016 MHz, two at 6030 MHz, and five at 6035 MHz). Of these 44 detected 6.0 GHz OH masers, 13 sites exhibit 6030 MHz OH masers, all 44 sites show the 6035 MHz transition, one site (G009.620+0.194) has the only 6016 MHz OH maser, and one site (W3(OH)) shows the only 6049 MHz OH maser. The 6016 MHz OH maser is the first OH maser of this transition detected in star formation regions. Investigations of the association between 6030/6035 MHz OH masers with 1665 MHz ground-state OH, 6.7 GHz methanol, and 22 GHz water masers show that 1665 MHz OH masers are good indicators of 6.0 GHz OH masers (29% detection rate), which is consistent with previous results. The majority (more than 77%) of 6030 and 6035 MHz OH masers are associated with 6.7 GHz methanol and/or 22 GHz water masers. Comparison between our spectra with previous spectra, we find that only two sources remain fairly stable since their discoveries. We identify 80 Zeeman pairs in 32 6.0 GHz OH maser sites with typical magnetic field strengths of less than 10 mG. The magnetic field directions derived from these 32 maser sites with Zeeman pairs are consistent with previous work, which indicates that the 6.0 GHz OH masers may be potential tracers of the large-scale Galactic magnetic field.

We assess the dark matter halo masses of luminous active galactic nuclei (AGNs) over the redshift range 0.2–1.2 using galaxy–galaxy lensing based on imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). We measure the weak lensing signal of a sample of 48,907 AGNs constructed using HSC and Wide-field Infrared Survey Explorer photometry. As expected, we find that the lensing mass profile of total AGN sample is consistent with that of massive galaxies (

10.61). Surprisingly, the lensing signal remains unchanged when the AGN sample is split into four host galaxy stellar mass bins. Specifically, we find that the excess surface density of AGNs residing in galaxies with high stellar masses significantly differs from that of the control sample. We further fit a halo occupation distribution model to the data to infer the posterior distribution of parameters including the average halo mass. We find that the characteristic halo mass of the full AGN population lies near the knee (

) of the stellar-to-halo mass relation (SHMR). Illustrative of the results given above, the halo masses of AGNs residing in host galaxies with high stellar masses (i.e., above the knee of the SHMR) fall below the calibrated SHMR while the halo masses of the low stellar mass sample are more consistent with the established SHMR. These results indicate that massive halos with a higher clustering bias tend to suppress AGN activity, probably due to the lack of available gas.

Observations suggest that filaments in molecular clouds can grow by mass accretion while forming cores via fragmentation. Here, we present one of the first large-sample studies of filament accretion using velocity gradient measurements of star-forming filaments on the ∼0.05 pc scale with NH3 observations of the Perseus Molecular Cloud, primarily obtained as a part of the Green Bank Ammonia Survey. In this study, we find significant correlations between the velocity gradient, velocity dispersion, mass per unit length, and number of cores per unit length of the Perseus filaments. Our results suggest a scenario in which filaments not only grow through mass accretion, but also form new cores continuously in the process, well into the thermally supercritical regime. Such behavior is contrary to that expected from isolated filament models but consistent with how filaments form within a more realistic cloud environment, suggesting that the cloud environment plays a crucial role in shaping core formation and evolution in filaments. Furthermore, even though velocity gradients within filaments are not oriented randomly, we find no correlation between velocity gradient orientation and the filament properties we analyzed. This result suggests that gravity is unlikely to be the dominant mechanism imposing order on the ∼0.05 pc scale for dense star-forming gas.

The structure of the magnetic reconnection boundary, particularly the presence of slow-mode shocks in the near-Earth magnetotail was studied by using magnetospheric multiscale (MMS) observations and 2.5D hybrid simulations. A total of 51 crossings of MMS from 2017 to 2021 were analyzed. We found that the detection percentage of slow-mode shocks in the near-Earth magnetotail is 41%–55%. Previous studies have only reported one slow-mode shock event in the near-Earth magnetotail and a slow-mode shock detection percentage of 10% or lower in the mid-to-distant magnetotail. It was observed that if the high-energy beam region data is removed from the slow-mode shock downstream observations then the detection of slow-mode shocks reduces, implying that the kinetic effects play an important role in the detection of slow-mode shocks. For the crossings where the interface was not identified as a slow-mode shock, it was found that the turbulence in those crossings can change the mass flux values and disrupt the detection of slow-mode shock. However, the macroscopic slow-mode shock-like structure stably exists around the magnetic reconnection interface, as most of the conditions for slow-mode shocks were satisfied. This result suggests that slow-mode shocks are a general feature of magnetic reconnection geometry. We find that the lack of detection of slow-mode shocks in previous observations and simulations can be explained by taking into account the kinetic structure of slow-mode shocks and the presence of turbulence.

The primary objective of this study is to develop a time-dependent model of the flaring atmosphere based on observational data. Here, we present, for the first time, a comparison between numerical simulations of the flaring emission, specifically focusing on the hydrogen Hα line, utilizing the FLARIX code and spectral observations of a compact C1.6 GOES-class flare observed on 2012 September 10, by the MSDP imaging spectrograph installed at the Białków Observatory. The Multichannel Subtractive Double Pass imaging spectrograph spectral data, collected with a temporal resolution as fine as 50 ms, enabled a comprehensive analysis of Hα line profiles and light curves measured within an area of the flare’s emission. An initial atmospheric model close to VAL-C, with a modified temperature in the upper chromosphere, was employed in simulations. To enhance temporal resolution, modulations of the nonthermal electron (NTE) beam’s parameters were introduced based on variations in observed hard X-ray (HXR) flux (using RHESSI data). The synthesized Hα line profiles were compared with the observed spectra. During the impulsive phase of the flare, the evolution of the observed and synthetic Hα line intensity agrees, but discrepancies were found in intensities at specific wavelengths of the Hα line profile. Fluctuations in the energy flux of NTEs exhibited a strong correlation with the Hα emission during the HXR pulse. After considering various effects (such as the filling factor FF = 0.20) that could influence observed emissions, relatively good agreement between theoretical and observed lines was achieved.
Dynamic 3D Simulation of Surface Charging on Rotating Asteroids

Published: December 2024

The surface-charging phenomenon of asteroids, mainly resulting from solar wind plasma and solar radiation, has been extensively studied. However, the influence of the asteroid’s rotation on surface charging is not yet fully understood. In this study, a neural network is established to replace numerical integration, improving the efficiency of dynamic 3D simulations. We simulate rotating asteroids and their surrounding plasma environments under various conditions, including the quiet solar wind and solar storms. Different minerals on the asteroid surface are also considered. Additionally, the effects of orbital motion and obliquity are studied for asteroids with rotation periods comparable to their orbital periods. The results show that under the typical solar wind, the maximum and minimum potentials of asteroids gradually decrease with increasing rotation periods, especially when the solar wind is obliquely incident. For asteroids with rotation periods longer than one week, this decreasing trend becomes extremely slow. During a solar storm, the solar wind plasma changes sharply, and the susceptibility of an asteroid’s surface potential to rotation is greatly pronounced. Surface minerals also play a role; plagioclase is the most sensitive mineral among those explored, while ilmenite appears indifferent to changes in rotation periods. Understanding the surface charging of asteroids under various rotation periods and angles is crucial for further research on solar wind plasma and asteroids’ surface dust motion, providing a reference for the safe landing and exploration of asteroids.
