Authors: Jayaputra Vitta Maitri Budhi , Putriningtyas Natalia Desy 
Published: June 2024

Background: Sports games with aerobic and anaerobic energy systems require muscular and cardiovascular endurance, as well as high dietary intake. Carbohydrate loading before training can maximize glycogen storage and carbohydrate oxidation, thereby increasing performance. Chocolate milk powder, as much as 45 g, contains 55 g of carbohydrates, contributing to 6-8% of total carbohydrate needs.
Objectives: Analyzing the effect of chocolate milk consumption on muscle endurance and maximum oxygen volume capacity (VO2 Max) in sports athletes at the BPPLOP Central Java Student Sports Education and Training Center.
Methods: Research with pretest-posttest control design with the same sample with a washout period. A sample of 47 athletes was taken using a total sampling technique, all used as a control group and treated for 6 days with 200 ml 2 hours before training. Measurement of endurance using the multistage fitness test. Test the difference in effect before and after treatment using the Paired Samples T-Test, while testing the difference between control and treatment groups using Mann Whitney.
Results: There was a significant effect between before and after consuming chocolate milk on increasing muscle endurance by 2150.64 ± 420.72 to 2314.47 ± 400.14 m and VO2 Max capacity by 53.95 ± 5.96 to 56.30 ± 5.62 ml/kg/minute with a p-value=0.00. There was a significant difference between the consumption of placebo and chocolate milk in increasing muscle endurance by 163.83 m and VO2 Max capacity by 2.34 ml/kg/minute with a p-value=0.00.
Conclusions: Carbohydrate loading by consuming 45 g of chocolate milk in 200 ml containing 55 g of carbohydrates before training for 6 days can affect increasing muscle endurance and VO2 Max capacity in sports athletes.

Case:
A 59-year-old woman with a history of left knee pain exacerbated by lymphatic filariasis underwent successful total knee replacement (TKR) for advanced osteoarthritis. Postoperatively, diligent adherence to compression bandaging, physiotherapy, and lymphatic flow promotion resulted in no lymphedema progression. During the 5-year follow-up, the patient showed improved Knee injury and Osteoarthritis Outcome Score and stable implant.

Conclusions:
Currently, there are no established protocols or formulated guidelines for TKR in patients with chronic filariasis. The preoperative lymphedema prevention must be tailor-made for each patient in the context of advanced osteoarthritis based on the functional lymphatic vessel status.
Hydrogen Geostorage in Organic-Rich Shales: Critical Insights Into the Role of Cushion Gas in Hydrogen Accumulation within Organic Nanoporous Systems
Authors: Alafnan Saad 
Published: June 2024

Summary
Depleted shale formations have the potential for hydrogen geostorage. The storage mechanisms, however, are complex and influenced by several factors including mineralogy, pore size distribution, residual hydrocarbons in place, and the choice of cushion gas. This study aims to investigate hydrogen distribution within this multiscale pore system, with a focus on understanding how hydrogen accumulates in the organic nanoporous network. Such insights are critical for the long-term storage and recovery assessments. Using molecular simulations, representative organic matter comprising nanoporous kerogen and nanopores of different sizes was constructed. Hydrogen intake of the organic system in the presence of residual amount of natural gas was quantified, considering multiple hydrogen injection scenarios. Despite stronger chemical affinity toward natural gas, hydrogen accumulated in all pore sizes, even the smallest, potentially beneficial for long-term storage but hindering rapid recovery. Moreover, the study was extended to investigate the role of cushion gas in the accumulation of hydrogen in organic structures. It was found that introducing cushion gases, such as methane and carbon dioxide, reduces hydrogen intake in the nanopores, with carbon dioxide being the most effective due to its stronger attraction to kerogen. Nitrogen, on the other hand, had relatively lower impact. The results were consistent with the observed trends in the analysis of the nonbonding energy of all systems. The results reported in this study provide critical insights into the factors influencing hydrogen accumulation in the organic constituents of shale formations for an optimized design of hydrogen geostorage in depleted shale gas reservoirs.

Published: June 2024

Abstract

The most widely used herbicide glyphosate contaminates surface waters around the globe. Both agriculture and urban applications are discussed as sources for glyphosate. To better delineate these sources, we investigated long-term time series of concentrations of glyphosate and its main transformation product aminomethylphosphonic acid (AMPA) in a large meta-analysis of about 100 sites in the USA and Europe. The U.S. data reveal pulses of glyphosate and AMPA when the discharge of the river is high, likely indicating mobilization by rain after herbicide application. In contrast, European concentration patterns of glyphosate and AMPA show a typical cyclic-seasonal component in their concentration patterns, correlating with patterns of wastewater markers such as pharmaceuticals, which is consistent with the frequent detection of these compounds in wastewater treatment plants. Our large meta-analysis clearly shows that for decades, municipal wastewater was a very important source of glyphosate has been municipal wastewater. In addition, European river water data show rather high and constant basic mass fluxes of glyphosate all over the year, not expected from herbicide application. From our meta-analysis, we define criteria for a source of glyphosate, which was hidden so far. Details from the meta-analysis and the knowledge that AMPA is a known transformation product of aminopolyphohsphonates let us hypothesize that also these antiscalants are an important source for glyphosate in Europe, where these compounds are used in detergents.

Published: June 2024

Abstract

While medieval embalming practices in Western Europe are attested historically and bioarcheologically, especially for famous historical figures, there are few recorded occurrences of this type of corpse preparation for a large number of archaeological individuals from the same lineage. Moreover, evidence of such practices mainly concerns adult individuals, whereas traces of child embalming are extremely rare. In 2017, the discovery of a crypt in the chapel of the Château des Milandes (Castelnaud-la-Chapelle, Dordogne, France) revealed a collective burial of the scattered remains of seven adults and five children of the aristocratic Caumont family, who died in the 16th and 17th centuries and whose skeletons all show stigmata from embalming practices. In 2021, another excavation in the chapel uncovered the individual grave of an elderly woman whose body was also embalmed. This skeletal sample provides a unique opportunity to examine the modus operandi of medieval embalming through the stigmata left on the cranium and appendicular skeleton and to compare mortuary protocols for adults and children. Our macroscopic and microscopic investigations revealed a thorough and highly stereotyped technical treatment that was similar for both adult and very young immature individuals and displays a skillset that was passed down locally over two centuries.

Abstract

Background
General Health Questionnaire-28 (GHQ-28) is a self-administered questionnaire for identifying non-psychotic and minor psychiatric disorders. It has been translated and used in different populations around the world. Main objective of this study was to evaluate the validity and reliability of Dari version of GHQ-28 among adult Afghan population.
Methods
This cross-sectional study was conducted between June and September 2023 among 1146 adults from diverse regions of Afghanistan. Internal Consistency Reliability was gauged through Cronbach’s Alpha. To assess the convergent validity of GHQ-28 subscales, Pearson correlation analyses were conducted, comparing the results with those obtained from the DASS-21 and CES-D 20. For validation, confirmatory factor analysis was used to determine the goodness-of-fit of the four construct models of GHQ-28 within the Afghan population.
Results
Among the 1146 study participants, majority (72.6%) were females with mean age of 30.2 years while 68.3% with experience of traumatic event in the past month. In this study, overall reliability of the Dari version of GHQ-28 using Cronbach’s alpha was 93.8%, which indicates an excellent internal consistency. For finding validity or goodness-of-fit, CFA was used in this study. The comprehensive or overall GHQ-28 model showed satisfactory fit, indicated by acceptable values for CFI (0.758), TLI (0.734), and RMSEA (0.109). For Somatic Symptoms, anxiety/insomnia, social dysfunction, and severe depression, the model demonstrated good fit, poor fit, good fit, and reasonably good fit, respectively. The overall GHQ-28 model showed satisfactory fit.
Conclusions
The reliability and validity of the Dari version of the GHQ-28 have been established, with satisfactory fit for overall model. The present findings can serve as a base or open the door for further research on the psychological well-being or distress of the Afghans. GHQ-28 should be further evaluated in different and specific populations. Also, this study reinforces the need to conduct further researches in translating GHQ-28 and then evaluating its validity and reliability in other languages spoken in Afghanistan.

Published: June 2024

Abstract

Introduction: Gaucher disease (GD1) is caused by the enzymatic deficiency of β-glucocerebrosidase. This leads to accumulation of sphingolipids in organs, such as the liver, spleen, and bone marrow. Bone involvement is frequent in GD1, causing pain, necrosis and even fractures or growth deficits in children, leading to painful surgeries and progressive decrease in quality of life.
Methodology: A non-experimental retrospective observational study was performed using a database of 30 patients with clinical suspicion and enzymatic and/or molecular confirmation of GD1; the numbers and percentages of occurrence for each sign were determined.
Results: Bone pain was the most common symptom and was reported in 23% of the sample. 13/30 (43%) patients had report of at least one radiograph requested during the study : 6 of them, with some bone alteration, being the most frequent : increases in acetabular coverage with signs of femoroacetabular impingement, decrease in height and morphology and Erlenmeyer deformity; 14/30 (48%) of the patients presented at least one result of Magnetic Resonance Imaging (MRI); in the femur MRI of 4 patients there was a decrease in the signal intensity of the bone marrow, both in T1 and T2 sequences, involving various bone areas and changes of infiltrative bone disease; finally in 7/30 (7. 5%) presented at least one bone densitometry result (DEXA): 3 presented low bone mineralization. The patients who present the p. Asn409Ser allele may present more predisposition to bone disease.
Conclusion: The present study highlights the importance of early diagnosis, to access timely treatment, to prevent bone complications typical of the disease, improving prognosis, quality of life and morbi-mortality in GD1.
Metabolomics and 13C Labelled Glucose Tracing to Identify Carbon Incorporation into Aberrant Cell Membrane Glycans in Cancer
Authors: Haab Brian , Reyes-Oliveras Alfredo , Sheldon Ryan , Ellis Abigail 
Published: June 2024

Abstract

Cell membrane glycans contribute to immune recognition, signaling, and cellular adhesion and migration, and altered membrane glycosylation is a feature of cancer cells that contributes to cancer progression. The uptake and metabolism of glucose and other nutrients essential for glycan synthesis could underlie altered membrane glycosylation, but the relationship between shifts in nutrient metabolism and the effects on glycans have not been directly examined. To address this possibility, we created a novel method that combines stable isotope tracing with metabolomics to enable direct observations of glucose allocation to nucleotide sugars and cell membrane glycans. We compared the glucose allocation to membrane glycans of two pancreatic cancer cell lines that are genetically identical but have differing energy requirements. The 8988-S cells had higher glucose allocation to membrane glycans and intracellular pathways relating to glycan synthesis, but the 8988-T cells had higher glucose uptake and commitment of glucose to non-glycosylation pathways. The cells lines differed in requirements of glucose for energy production, resulting in differences in glucose bioavailability for glycan synthesis. The workflow demonstrated here enables studies on the effects of metabolic shifts on the commitment of media nutrients to cell-membrane glycans. The results support a flux-based regulation of glucose commitment glycosylation and a mode of metabolic control of cell functions such signaling, immune recognition, and adhesion and migration.

Abstract

The organic pollutants promote significant risks to both human health and environmental sustainability. These compounds have seen a dramatic increase in diversity and quantity, infiltrating bodies of water, marine environments, and living organisms. Some factors contribute to pollutant emissions, such as road traffic and industrial activities and it leads to an spatiotemporal variability. Between the organic pollutants, Trace Organic Contaminants (TrOCs), which comprise a diverse range of industrial chemicals, pharmaceutical residues, and pesticides, are also gaining attention for their toxic effects on aquatic organisms and plants. Thus, this work aimed to evaluate the occurrence of TrOCs deposited in Eugenia uniflora leaves from urban areas and preserved forests during the four seasons of the year. The identification of emerging trace organic contaminants were analyzed by GC-MS and GC-FID. This analysis allowed us to identify TrOCs and some of them related to endocrine disorders. These TrOCs differed depending on the region and season of the year in which the leaves were collected, and they were present even in plants cultivated in preserved forests.
