Published: February 2024

The cutaneous absorption parameters of xenobiotics are crucial for the development of drugs and cosmetics, as well as for assessing environmental and occupational chemical risks. Despite the great variability in the design of experimental conditions due to uncertain international guidelines, datasets like HuskinDB have been created to report skin absorption endpoints. This review updates available skin permeability data by rigorously compiling research published between 2012 and 2021. Inclusion and exclusion criteria have been selected to build the most harmonized and reusable dataset possible. The Generative Topographic Mapping method was applied to the present dataset and compared to HuskinDB to monitor the progress in skin permeability research and locate chemotypes of particular concern. The open-source dataset (SkinPiX) includes steady-state flux, maximum flux, lag time and permeability coefficient results for the substances tested, as well as relevant information on experimental parameters that can impact the data. It can be used to extract subsets of data for comparisons and to build predictive models.

Authors: Liu Xuebang , Yu Shuying , Yang Zhiwei , Dong Jianquan , Peng Jian
Published: February 2024

Global warming accelerates water cycle, causing more droughts globally that challenge monitoring and forecasting. The Standardized Precipitation Evapotranspiration Index (SPEI) is used to assess drought characteristics and response time of natural and economic systems at various timescales. However, existing SPEI datasets have coarse spatial or temporal resolution or limited spatial extent, restricting their ability to accurately identify the start or end dates or the extent of drought at the global scale. To narrow these gaps, we developed a global daily SPEI dataset (SPEI-GD), with a 0.25° spatial resolution from 1982 to 2021 at multiple timescales (5, 30, 90, 180 and 360 days), based on the precipitation from European Center for Medium Weather Forecasting Reanalysis V5 (ERA5) dataset and the potential evapotranspiration from Singer’s dataset. Compared to widely used SPEIbase dataset, the SPEI-GD can improve the spatial-temporal resolution and the accuracy of SPEI in areas where meteorological sites are lacking. The SPEI-GD significantly correlates with site-based SPEI and soil moisture. Our dataset solidly supports sub-seasonal and daily-scale global and regional drought research.

Published: February 2024

The incidence of hepatocellular carcinoma (HCC) in non-cirrhotic livers is rising significantly, but clear risk factors for screening remain elusive. This study sought to characterize non-cirrhotic HCC etiologies. HCC cases from 2009 to 2020 in a Dutch referral center were examined, revealing 371 out of 1654 cases (22%) as non-cirrhotic. Notably, the incidence of non-cirrhotic HCC increased by 61% in the time frame between 2009 and 2020. Interestingly 39% of non-cirrhotic HCC cases had cryptogenic origins. Cryptogenic non-cirrhotic HCC exhibited similarities with non-cirrhotic NAFLD HCC, but displayed advanced tumor stages, lower surgical rates, and a more frequent presence of symptoms, which substantiated in poor survival rates. Advanced cryptogenic non-cirrhotic HCC stages exhibited elevated serum interleukin-6 levels compared to non-cirrhotic HCC with defined etiologies. Comparative analysis encompassing cryptogenic and NAFLD non-cirrhotic HCC cohorts and controls unveiled comparable circulating immune biomarker profiles and PNPLA3 polymorphisms. To conclude, the primary etiology of non-cirrhotic HCC in our cohort has not defined risk factors. This cryptogenic variant exhibits distinct traits, such as advanced tumors and increased symptoms, and most resemble burned-out NAFLD. Understanding this HCC variant is crucial for improving screening and management strategies.
Design based synthetic imputation methods for domain mean
Authors: Bhushan Shashi , Kumar Anoop , Pokhrel Rohini , Bakr M. E. , Mekiso Getachew Tekle
Published: February 2024

In real life, situations may arise when the available data are insufficient to provide accurate estimates for the domain, the small area estimation (SAE) technique has been used to get accurate estimates for the variable under study. The problem of missing data is a serious problem that has an impact on sample surveys, but small area estimates are especially prone to it. This paper is a basic effort that suggests design based synthetic imputation methods for the domain mean estimation using simple random sampling in order to address the issue of missing data under SAE. The expression of the mean square error for the proposed imputation methods are obtained up to first order approximation. The efficiency conditions are determined and a thorough simulation study is carried out using artificially generated data sets. An application is included with real data that further supports this study.
The mental burden of stay-at-home order extensions during COVID-19
Authors: Segovia Michelle S. , Huseynov Samir , Palma Marco A. , Nayga Rodolfo M.
Published: February 2024

This study evaluates the psychological impact of stay-at-home extension orders during COVID-19 and its relationship with individuals’ expectations on the duration of the extensions. An online survey was administered to 1259 US adult residents to measure symptoms of post-traumatic stress disorder (PTSD), anxiety and stress induced by different stay-at-home order extensions using hypothetical length scenarios. We find that individuals exposed to two 2-week order extensions exhibit higher levels of stress and anxiety compared to those exposed to a single 4-week extension. We also find that subjects with longer expected extensions exhibit more signs of psychological damage than those with shorter expected extensions. Furthermore, we find that the negative psychological consequences of providing two shorter extensions is observed only among subjects with extension expectations of four weeks or less. Our results demonstrate that people’s expectations affect the level of psychological damage caused by lockdown mandates. Our findings suggest that whenever lockdown extensions are necessary, reduced psychological distress may be possible by implementing a one-time restriction, rather than extending multiple smaller extensions perhaps due to manipulation of personal expectations.
Protoporphyrin IX in serum of high-grade glioma patients: A novel target for disease monitoring via liquid biopsy
Authors: Walke Anna , Krone Christopher , Stummer Walter , König Simone , Suero Molina Eric
Published: February 2024

High-grade gliomas (HGG) carry a dismal prognosis. Diagnosis comprises MRI followed by histopathological evaluation of tissue; no blood biomarker is available. Patients are subjected to serial MRIs and, if unclear, surgery for monitoring of tumor recurrence, which is laborious. MRI provides only limited diagnostic information regarding the differentiation of true tumor progression from therapy-associated side effects. 5-aminolevulinic acid (5-ALA) is routinely used for induction of protoporphyrin IX (PpIX) accumulation in malignant glioma tissue, enabling improved tumor visualization during fluorescence-guided resection (FGR). We investigated whether PpIX can also serve as a serum HGG marker to monitor relapse. Patients (HGG: n = 23 primary, pHGG; n = 5 recurrent, rHGG) undergoing FGR received 5-ALA following standard clinical procedure. The control group of eight healthy volunteers (HCTR) also received 5-ALA. Serum was collected before and repeatedly up to 72 h after drug administration. Significant PpIX accumulation in HGG was observed after 5-ALA administration (ANOVA: p = 0.005, post-hoc: HCTR vs. pHGG p = 0.029, HCTR vs. rHGG p = 0.006). Separation of HCTR from pHGG was possible when maximum serum PpIX levels were reached (CI95% of tMax). ROC analysis of serum PpIX within CI95% of tMax showed successful classification of HCTR and pHGG (AUCROC 0.943, CI95% 0.884–1.000, p < 0.001); the optimal cut-off for diagnosis was 1275 pmol PpIX/ml serum, reaching 87.0% accuracy, 90.5% positive predictive and 84.0% negative predictive value. Baseline PpIX level was similar in patient and control groups. Thus, 5-ALA is required for PpIX induction, which is safe at the standard clinical dosage. PpIX is a new target for liquid biopsy in glioma. More extensive clinical studies are required to characterize its full potential.
New age constraints for human entry into the Americas on the north Pacific coast
Authors: Steffen Martina L.
Published: February 2024

The timing of the initial peopling of the Americas is unresolved. Because the archaeological record necessitates discussion of human entry from Beringia into southern North America during the last glaciation, addressing this problem routinely involves evaluating environmental parameters then targeting areas suitable for human settlement. Vertebrate remains indicate landscape quality and are a key dataset for assessing coastal migration theories and the viability of coastal routes. Here, radiocarbon dates on vertebrate specimens and archaeological sites are calibrated to document species occurrences and the ages of human settlements across the western expansion and decay of the Cordilleran Ice Sheet (CIS) during the Late Wisconsin Fraser Glaciation in four subregions of the north Pacific coast of North America. The results show archaeological sites occur after glacial maxima and are generally consistent with the age of other securely dated earliest sites in southern North America. They also highlight gaps in the vertebrate chronologies around CIS maxima in each of the subregions that point to species redistributions and extirpations and signal times of low potential for human settlement and subsistence in a key portion of the proposed coastal migration route. This study, therefore, defines new age constraints for human coastal migration theories in the peopling of the Americas debate.
NSCSO: a novel multi-objective non-dominated sorting chicken swarm optimization algorithm
Authors: Huang Huajuan , Zheng Baofeng , Wei Xiuxi , Zhou Yongquan , Zhang Yuedong
Published: February 2024

Addressing the challenge of efficiently solving multi-objective optimization problems (MOP) and attaining satisfactory optimal solutions has always posed a formidable task. In this paper, based on the chicken swarm optimization algorithm, proposes the non-dominated sorting chicken swarm optimization (NSCSO) algorithm. The proposed approach involves assigning ranks to individuals in the chicken swarm through fast non-dominance sorting and utilizing the crowding distance strategy to sort particles within the same rank. The MOP is tackled based on these two strategies, with the integration of an elite opposition-based learning strategy to facilitate the exploration of optimal solution directions by individual roosters. NSCSO and 6 other excellent algorithms were tested in 15 different benchmark functions for experiments. By comprehensive comparison of the test function results and Friedman test results, the results obtained by using the NSCSO algorithm to solve the MOP problem have better performance. Compares the NSCSO algorithm with other multi-objective optimization algorithms in six different engineering design problems. The results show that NSCSO not only performs well in multi-objective function tests, but also obtains realistic solutions in multi-objective engineering example problems.

Published: February 2024

Knowledge about biodiversity changes during transitions from glacial landscape to lake formation is limited to contemporary studies. Here, we combined analyses of lithology, chronology and geochemistry with sedimentary ancient DNA metabarcoding to assess such transition in maritime Antarctica. We inferred three paleoenvironmental stages covering the Holocene glacier retreat process. From 4900 to 3850 years before the present, we found the lowest prokaryotic richness/diversity, with bacterial taxa indicators associated to soil and terrestrial environments. From 3850 to 2650 years before the present, a higher carbon content, higher Carbon/Nitrogen variability, increased species richness/diversity, and prokaryotic taxa indicators of long-term energy starvation were detected. Finally, from 2650 to 1070 years before the present, we inferred the onset of a genuine lacustrine environment holding stable Carbon/Nitrogen ratios and the highest prokaryotic diversity, with known aquatic bacterial taxa. Our study unveils for the first time the evolution from a glacier-covered to a freshwater lake through a millennial scale.
Magma budget, plutonic growth and lateral spreading at Mt. Etna
Authors: Palano Mimmo , Pezzo Giuseppe , Chiarabba Claudio
Published: February 2024

The quantitative estimation of eruptible magma is essential to assess volcanic hazard. In case of high and frequent volcanic activity, different episodes and cycles can be observed and used to gain insights on magma residence and volcano dynamics. Here, by using surface ground deformation for 26 inflation and 14 deflation phases at Mt. Etna, we inferred two partially overlapping magmatic reservoirs located beneath the summit area in the 4-9 km (inflation sources) and in the 3-6 km (deflating sources) depth ranges. Our geodetic models highlight a continuous magma supply of 10.7 ×106 m3/yr that took place in the last two decades. About 28.5% of this magma (i.e. volume loss inferred by geodetic models) contributed to the effusive activity at the surface, while the remaining 71.5% fed the endogenous volumetric growth of the plutonic crystallized mush and promoted the lateral spreading of Mt. Etna. The consistency of this behavior through time sets strong constraints on the eruptible quantity of magma in forecasting activity during a paroxysm.
Cryo-EM analyses of dimerized spliceosomes provide new insights into the functions of B complex proteins
Authors: Zhang Zhenwei , Kumar Vinay , Dybkov Olexandr , Will Cindy L , Urlaub Henning , Stark Holger , Lührmann Reinhard
Published: February 2024

The B complex is a key intermediate stage of spliceosome assembly. To improve the structural resolution of monomeric, human spliceosomal B (hB) complexes and thereby generate a more comprehensive hB molecular model, we determined the cryo-EM structure of B complex dimers formed in the presence of ATP$$\gamma$$
γ
S. The enhanced resolution of these complexes allows a finer molecular dissection of how the 5′ splice site (5′ss) is recognized in hB, and new insights into molecular interactions of FBP21, SNU23 and PRP38 with the U6/5′ss helix and with each other. It also reveals that SMU1 and RED are present as a heterotetrameric complex and are located at the interface of the B dimer protomers. We further show that MFAP1 and UBL5 form a 5′ exon binding channel in hB, and elucidate the molecular contacts stabilizing the 5′ exon at this stage. Our studies thus yield more accurate models of protein and RNA components of hB complexes. They further allow the localization of additional proteins and protein domains (such as SF3B6, BUD31 and TCERG1) whose position was not previously known, thereby uncovering new functions for B-specific and other hB proteins during pre-mRNA splicing.
Hyperacetylated histone H4 is a source of carbon contributing to lipid synthesis

Histone modifications commonly integrate environmental cues with cellular metabolic outputs by affecting gene expression. However, chromatin modifications such as acetylation do not always correlate with transcription, pointing towards an alternative role of histone modifications in cellular metabolism. Using an approach that integrates mass spectrometry-based histone modification mapping and metabolomics with stable isotope tracers, we demonstrate that elevated lipids in acetyltransferase-depleted hepatocytes result from carbon atoms derived from deacetylation of hyperacetylated histone H4 flowing towards fatty acids. Consistently, enhanced lipid synthesis in acetyltransferase-depleted hepatocytes is dependent on histone deacetylases and acetyl-CoA synthetase ACSS2, but not on the substrate specificity of the acetyltransferases. Furthermore, we show that during diet-induced lipid synthesis the levels of hyperacetylated histone H4 decrease in hepatocytes and in mouse liver. In addition, overexpression of acetyltransferases can reverse diet-induced lipogenesis by blocking lipid droplet accumulation and maintaining the levels of hyperacetylated histone H4. Overall, these findings highlight hyperacetylated histones as a metabolite reservoir that can directly contribute carbon to lipid synthesis, constituting a novel function of chromatin in cellular metabolism.

To fulfill Paris Agreement commitments, an effective strategy involves advancing renewable energy (RE) adoption, especially in 3T (underdeveloped, frontier, outermost) regions dependent on diesel power. Nain Island, a 3T area, relies on a 200kW diesel plant operating 7 hours/day for 1004 households. This research aims to extend electricity services to 24 hours/day without extra fuel by integrating a 300 kWp photovoltaic (PV) plant with the existing diesel setup. Determining PV capacity considers parameters like diesel capacity, load profile, households, and outage rates. Implementing the PV plant encounters challenges due to limited land and hilly terrain. The solution proposes floating PV plant technology, globally successful and applicable in Indonesia. Placement on the northern coastal area of Nain Island, near the existing diesel plant, addresses land limitations.

This study aimed to analyse potential and competitiveness of sustainable mangroves in Aceh Jaya region as an alternative tourism destination. The ecotourism potential was identified from the existing onsite biodiversity, while the competitiveness level was investigated by distributing a questionnaire to 100 visitors asked about their perceptions of attraction, accessibility, ancillary services, amenities and activities regarding the mangrove site. A qualitative descriptive analysis was used to investigate the ecotourism potential and the competitiveness level was evaluated by scoring the competitiveness attributes on a 1- to 4-point scale where 1.00-1.74 (very low); 1.75-2.49 (low); 2.50–3.24 (high); and 3.25-4.00 (very high). The results on the biodiversity assessment showed that there are six species of mangrove vegetations were detected at this site, including Rhizopora mucronata, Rhizopora apiculata, Rhizopora stylosa, Bruguiera cylindrical, Bruguiera gymnorhiza, and Nypah fruticans. In this ecosystem, the existence of crocodiles in captivity and specific aquatic wildlife (i.e., Cerithidea sp.) was also observed. Regarding the competitiveness level, the highest performance score was the mangrove “attraction” (scored 3.29), followed by “amenities” (scored 3.06) and “ancillary services” (scored 2.99), whereas the others were scored with the lowest performance attributes. To increase competitiveness, it is necessary to improve transportation and public facilities at mangrove ecotourism location.

An emerging concept of the “Blue Economy” emphasizes using ocean resources sustainably to improve livelihoods and spur economic growth while marine ecosystems are kept in good condition. Utilising the Marine Ecological Carrying Capacity (MECC) Index, one can determine how well marine ecosystems can support human activity while preserving their ecological integrity. By a case study in the East Nusa Tenggara coastal area, this study aims to evaluate the opportunities and challenges associated with implementing the MECC in the Blue Economy scheme. The case study has been analysed using a comprehensive evaluation index system for coordinated development among marine resources, the environment, and social-ecological systems. The study also reviews relevant literature on the Blue Economy and the New Ocean Economy. The study has offered a quantitative evaluation of the Blue Economy Index’s economic effects, with an emphasis on Indonesia. The study found that effective implementation of the Index in the Blue Economy could increase the ocean economy’s contribution to East Nusa Tenggara’s GDP by at least 2–3%.

The mangrove forest in Pasir Timbul, Sungsang IV Village, Banyuasin Regency, part of mangrove area within the Air Telang Protected Forest Area, is experiencing pressure from changes in land cover. A rapid survey to determine the vertebrate diversity in Pasir Timbul, at the tip of the Air Telang Protected Forest area was conducted in early June 2023. The purpose of the survey is to propose species priority in conservation within context species and habitat management plan. Vertebrate surveys were carried out rapidly using several methods adapted to certain taxa levels, namely amphibians and reptiles, fish, birds and mammals. Priority for fauna conservation in the Air Telang Protected Forest (study area) for reptiles: Crocodylus porosus (Protected under Indonesian law), Fishes: Eleutheronema tetradactylum (Endangered by IUCN), Birds: Anhinga melanogaster (Protected), Haliastur indus (Protected), Microhierax fringillarius (Protected), Rhipidura javanica (Protected), and Mammals including the long-tailed macaque Macaca fascicularis (Endangered), langurs Trachypithecus cristatus (Vulnerable), and Prionailurus sp. Conservation efforts need to be increased because this area as buffer zone of Berbak Sembilang National Park, having high carbon absorption, and provide a breeding ground for fish, shrimp and crabs. It is clear the site is habitat for various fauna (including protected ones), as well as other ecological functions such as breaking waves, resisting seawater intrusion and abrasion.

The ‘Blue Economy’ concept aims to harness marine resources for economic growth and environmental sustainability, encompassing sectors like tourism, maritime transport, energy, fishing, and biotechnology. It contributes to global economic growth by creating jobs and supporting livelihoods. However, it faces challenges like overfishing, pollution, and climate change, which threaten marine ecosystem health. To address these challenges, cooperation, investment in research, innovation, and technology are needed. This study used a database from Scopus and analysed using the qualitative meta data literature review method of bibliometric analysis with posit RStudio. The result was 563 documents (global) found from a search on Scopus using the keyword “blue economy,” however only thirteen (13) (or 2.3% of the global) were associated with Indonesia. This study found that the future topic of blue economy research in Indonesia and at global level is different. The Indonesian research trend topic for the blue economy is the governance approach and the involvement and relationship between stakeholders while at the global level the trend topic is the economy, oceanography, biodiversity, environmental protection to the investment mechanism with a blue economy approach.

Published: February 2024

Indonesia implements the prevention of IUU fishing in ports using the PSM Agreement 2009. In its implementation, the Government of Indonesia designated port of PSMA implementing by establishing four ports, namely 3 fishing ports and 1 public port. The diversity of these types of ports has an impact on differences in the implementation of foreign fishing vessels entering Indonesian jurisdiction. This research is descriptive by using normative and comparative juridical methods. The results of this study reveal that the implementation of PSC in ports uses the Tokyo MoU, and fishing ports are determined using the 2009 PSM Agreement. This difference in legal basis causes confusion in law enforcement for IUU Fishing as a party to the PSM Agreement, so that an integrated legal arrangement is needed between public ports which are the authority of the Ministry of Transportation and fishing ports which are the authority of the Ministry of Maritime Affairs and Fisheries.
