Published: January 2024

Abstract

This research explores thraustochytrids, microorganisms with promising applications in sustainable docosahexaenoic acid (DHA) and odd-chain fatty acid production. The study specifically focuses on thraustochytrids isolated from a fishing village in the northern coastal area of Java, Indonesia, known for its significant organic content. Eight isolates were obtained from this coastal environment, demonstrating robust growth and lipid production capabilities. Notably, isolate BML-38 exhibited superior biomass and lipid production compared to commercial thraustochytrid ATCC strains, particularly in crude glycerol-based media. This positions it as a strong candidate for sustainable and cost-effective lipid production. BML-38 also produced a higher concentration of pentadecanoic acid (C15:0) and a similar concentration of heptadecanoic acid (C17:0), in addition to DHA. The outcomes of this investigation open new avenues, as thraustochytrids from the coastal area exhibit the capacity to utilize waste materials while competitively producing valuable compounds such as odd-chain fatty acids and DHA. This dual capability positions these strains as noteworthy contributors to sustainable lipid production and waste remediation strategies.
Fast Simulations of the Multi-Album Collector
Authors: Barak-Pelleg Dina , Berend Daniel 
Published: January 2024

Abstract
Our starting point is the coupon collector's problem. In this problem, there are $n$ coupons that are drawn uniformly randomly with replacement. The question is how many drawings on average are needed to collect at least one copy (or some other predetermined number $m$ of copies) of each coupon?
The problem may be traced back to the $18$-th century, having been mentioned already by de Moivre. Numerous questions have been posed based on the problem since its inception, and it turned out to appear naturally in many applications.
A naive simulation of the process is trivial to implement. However, the runtime of this algorithm makes it impractical for large values of $n$. We present here an alternative view of the coupon collecting process, for coupons with any probabilities, that allows us to increase the range of $n$-s (and $m$-s) for which the simulation may be run. For equiprobable coupons, we present additional improvements, making the simulation possible in a very short time practically for any $n$. More precisely, we show that the runtime of our algorithm is $\Theta(\max\{m,\log n\})$.
We present theoretical results concerning some of the quantities relevant to our algorithms and conduct simulations to test the algorithms in practice.

Published: January 2024

Abstract

The widespread use of mobile telephony and the internet constitutes an asset for digitalization in the agricultural sectors in Africa. Cotton being the leading export crop in Benin, this study aims to understand the determinants of the adoption of digitalization (use of digital machines, membership of a social network for information exchange, use of a mobile money account) by cotton producers in the Municipality of Banikoara. In this context, a socio-economic survey was carried out with a sample of 314 producers, obtained by purposive sampling. The binary logistic regression method made it possible to identify the factors affecting the adoption of digitalization. Thus, the level of banking, the use of labor, the area of cotton sown and knowledge of agricultural information and exchange platforms had a significant impact on the use of digital machines in agriculture. Membership of a social network for information exchange between producers was influenced by the level of banking, the type of cotton grown, strengthening of relationships with others, the risk linked to the use of digitalization and the assessment of the level of security of digitization by the producer. Finally, the level of banking, the exercise of a secondary activity and the use of labor were the significant variables in the adoption of mobile money by cotton farmers in Banikoara. However, the use of more advanced technologies such as drones and sensors was not yet a reality for these producers. This information is very useful for any project to popularize these new technologies.
Primary Gamma-knife Radiosurgery for Quasi-symptomatic Third Ventricular Colloid Cyst: A Case Report and Review of Literature
Authors: Tripathi Manjul , Verma Onam , Kaur Rupinder , Kumar Narendra 
Published: January 2024

Abstract
Colloid cysts are rare benign tumors most commonly occurring in the third ventricle. Conventional open surgery for symptomatic cases may be associated with complications and a high rate of recurrence. Minimally symptomatic or incidental colloid cyst pose as a treatment dilemma due to a slight but devastating possibility of late progression and sudden death. Stereotactic radiosurgery may be the middle-of-the-road solution in such a vignette. Given its safety profile and clinico-radiological efficacy, GKRS may find a role in the treatment protocol of colloid cyst.
Comparison of spinal anesthesia and local anesthesia in percutaneous interlaminar endoscopic lumbar discectomy for L5/S1 disc herniation: a retrospective cohort study
Authors: Liu Guanyi , Zhang Jiawei , Zhang long , Yuan Liyong , Wang Xuan , Tursunmamat Dilraba 
Published: January 2024

Abstract

Background:
Interlaminar endoscopic lumbar discectomy (IELD) is a prevalent method for the management of lumbar disc herniation. Local anesthesia (LA) is frequently employed during IELD, albeit with its merits and drawbacks. The spinal anesthesia (SA) represents a feasible anesthetic strategy for IELD; however, the availability of clinical research data is currently limited.
Methods:
The propensity score matching was conducted to ensure comparability of the SA and LA groups. The outcome measures were operation time, intraoperative visual analogue scale (VAS) for pain, need for adjuvant analgesia, intraoperative vital signs, blood loss, adverse surgical events, anesthesia-related complications, postoperative bedrest duration, VAS for pain at 2 hours postoperatively, Oswestry Disability Index score (ODI), satisfaction with surgical efficacy, and willingness to undergo reoperation at 6 months postoperatively.
Results:
Fifty-six patients were assigned to each group. Significant differences were found between the groups in terms of intraoperative VAS for pain, use of adjuvant analgesics, willingness to undergo reoperation, maximum intraoperative systolic blood pressure and variability (P < 0.05). Compared to the LA group, the SA group had lower VAS for pain at 2 hours postoperatively, a longer operation time, longer duration of postoperative bedrest, and more anesthesia-related complications (P < 0.05). No significant intergroup differences were detected in intraoperative heart rate variability, blood loss, ODI, satisfaction with surgical efficacy, and surgery-related complications (P > 0.05).
Conclusion:
The SA for IELD provides superior anesthesia and more stable hemodynamics compared to LA but may increase the risk of postoperative complications.

Authors: Comba Ozge Begum , Pasaoglu Ercan , Beyazal Muhammet 
Published: January 2024

Abstract

Purpose
To evaluate the interocular parameters between eyes according to ocular dominance using swept-source optical biometry.
Methods
This study included 227 individuals who visited the clinic for routine control. Enrolled patients underwent swept-source optical biometry. Uncorrected (UCVA) and best-corrected (BCVA) visual acuities were also recorded. Biometric data included axial length (AL), anterior chamber depth (ACD), crystalline lens thickness (LT), horizontal keratometry (K1), vertical keratometry (K2), white-to-white (WTW), Chang-Waring. chord distance (CWC-D) and Chang-Waring chord angle (CWC-A). Pearson's correlation coefficient was applied to evaluate the relationship between ocular parameters, spherical equivalent (SE) and visual acuity. Ocular dominance was diagnosed using the hole in the card test.
Results
The mean age of the participants was 48.72 ± 16.17 years (range: 18–68). Among the patients, the right eye (n = 155, 68.2%) was the dominant eye in the majority of cases. The dominant and nondominant eyes did not differ significantly in terms of ocular parameters (AL, WTW, ACD, LT, K1, K2, chord mu length). SE and visual acuity were not affected by ocular dominance. The correlation was conducted between the biometric variables, and it was observed that chord mu length showed a negative correlation with AL, ACD, WTW and a positive correlation with LT and SE in both groups.
Conclusion
No significant difference in dominance was found between eyes in patients with low (< 2D) anisometropia and low interocular best-corrected VA difference (< 0.2 logMAR units).

Published: January 2024

Abstract
Background
Necrotizing Fasciitis (NF) is a rapidly progressing infectious disease with a high mortality rate. It affects the soft tissue involving the fascia and subcutaneous tissue. In the case of thoracic, NF is associated with a significantly higher lethality. Group A streptococci are the most common pathogens of this infection. Early diagnosis, rapid and radical surgical therapy and antibiotic treatment are crucial for a successful outcome.
Case presentation:
This report outlines a case of a medical professional in his mid-60s, who developed NF in his right arm and hemithorax, likely contracted from a patient he treated. He presented himself at our clinic with chest pain, general weakness and a moderate fever. In addition, he had clear signs of infection and an inflamed, swollen area on the right chest wall. Despite the severity of the infection, quick recognition, immediate surgical intervention and intensive care management resulted in a successful outcome. Gene sequencing confirmed a match of the superantigens and the serotype emm1.0 of the streptococcus pyogenes with those of the patient he had treated shortly before.
Conclusion
This case emphasizes the critical role of early detection, rapid surgical debridement and broad-spectrum antibiotic therapy in managing NF. It also underlines the occupational risks faced by healthcare workers, highlighting the importance of strict adherence to infection control protocols. The report aims to raise awareness of NF, advocating for its consideration when patients present systemic infection signs, particularly in emergency departments.
Life Cycle of Deep Cloud Systems of Indian Summer Monsoon using High Temporal Resolution Satellite Data
Authors: PHADTARE JAYESH , Bhat G S 
Published: January 2024

Abstract
Life cycle characteristics of deep cloud systems (CSs) formed over India and the surrounding oceans during the summer monsoon season are reported using half-hourly geostationary satellite data. An automated cloud tracking algorithm based on the area overlap method is used. We show that the larger CSs tend to live longer and grow deeper, with some convective towers growing deeper than the tropopause. The CSs over Central India are shorter-lived than those over the Bay of Bengal. Interestingly, they have similar sizes as the peak growth rate of the former is about twice that of the latter, suggesting stronger updrafts in the continental systems. In June and September, CSs formations predominately occur over the orographic features, whereas in July-August, it is associated with the monsoon trough. CSs show a tendency to propagate upwind of the lower tropospheric winds. Merging contributes significantly to the growth and longevity of CSs. This suggests that large and long-lived CSs are formed when the environment can trigger and sustain multiple CSs in close vicinity. The peak in the CS size occurs, around halfway through its lifetime, chronologized by systematic merging and splitting events, i.e., CSs normally have symmetrical growth and decay phases. Whereas the minimum mean cloud-top temperature of CS occurs during the second quarter. This is in consensus with the vertical build-up of convective towers followed by horizontal growth via anvil spreading.
Accounting Choices in Data Envelopment Analysis

Published: January 2024

Abstract

Due to the increasing availability of large-scale digitalized databases containing summarised financial accounting measures, a growing number of DEA models are using these variables. Where only accounting measures are used, we term these "FinDEA" models. Accounting measures are subject to accounting choices regarding recognition and measurement, which means that they are not equivalent to underlying physical measures used in conventional DEA. This paper investigates the impact of accounting choices on FinDEA results when using alternative accounting measures of capital. Using both simulated and real-world data, we find that accounting choices impact FinDEA results, with the magnitude influenced by heterogeneity in accounting choices and sample sizes. Our results suggest that the variation in accounting choices needs to be considered when designing DEA models using accounting measures.
Flagellin-B-expressing Salmonella Typhimurium Improves the Efficacy of Anti-PD- 1 Therapy by Remodeling the Tumor Microenvironment in Colorectal Cancer

Published: January 2024

Abstract
Although patients with colorectal cancer (CRC) typically respond poorly to conventional chemotherapy, it remains the standard treatment. Clinical studies involving CRC patients have reported that chemotherapy promotes the infiltration of CD8+ T cells into the tumor and improves the therapeutic response to immune checkpoint inhibitors, such as those targeting programmed cell death protein 1 (PD-1). Salmonella typhimurium contributes to tumor eradication by transforming the immunosuppressive tumor microenvironment (TME) into an immunogenic one, which improves the antitumor immune response; however, the combined effect of S. typhimurium therapy and PD-1 blockade on the TME is not well understood. Here, we investigated the anticancer effects of a combination therapy comprising an attenuated S. typhimurium strain engineered to secrete Vibrio vulnificus flagellin B (S.ΔppGpp FlaB) and an anti-PD-1 antibody. We found that S.ΔppGpp FlaB significantly promoted the infiltration of immune cells, including M1 macrophages, dendritic cells, and CD8+ T cells, into the tumor, while increasing tumor PD-1 and PD-L1 expression via the AKT/PI3K pathway. Moreover, our encouraging results in tumor-bearing mouse models suggest that combining S.ΔppGpp FlaB with PD-1 blockade could be a promising strategy for enhancing the efficiency of anti-PD-1 therapy in patients with CRC.

Published: January 2024

Abstract
Background: Most metastatic lung tumors present as solid nodules on chest computed tomography (CT). In contrast, ground-glass opacity on chest computed tomography usually suggests low-grade malignant lesions such as adenocarcinoma in situ or atypical adenomatous hyperplasia of the lung.
Case presentation: A 75-year-old woman with a history of gastric cancer surgery approximately 5 years prior was referred to the Department of Thoracic Surgery at our hospital because of two newly appearing pulmonary ground-glass opacity-dominant nodules on chest computed tomography. She had two ground-glass opacities in the right lower lobe: one in the S6 segment was 12 mm and the other in the S10 segment was 8 mm. On chest computed tomography 15 months prior to referral, the lesion in the S6 segment was 8 mm, and the lesion in the S10 segment could not be identified. She was suspected to have primary lung cancer and underwent wide-wedge resection of the nodule in the S6 segment. In the resected specimen, polygonal tumor cells infiltrated the alveolar septa, with some tumor cells exhibiting signet ring cell morphology. Based on morphological similarities to the tumor cells of previous gastric cancers and the results of immunostaining, the patient was diagnosed with lung metastases of gastric cancer.
Conclusions: Pulmonary nodules in patients with a history of cancer in other organs, even if ground-glass opacity is predominant, should also be considered for the possibility of metastatic pulmonary tumors if they are growing rapidly.

Abstract
Purpose: The primary aim of this study was to investigate if diurnal oscillation in maximal fat oxidation and substrate oxidation rates during exercise exists in subjects with Metabolic syndrome.
Methods: In a randomized crossover design, 14 MetS patients were assigned to two graded exercise tests conditions performed in the morning (between 7:00 and 9:00 a.m) and in the afternoon (between 4:00 and 5:00 p.m).
Results: MFO increased by 20.56 % from morning to afternoon (time of day, p=0.0002, η2p = 0,69) and this was independent of gender (gender*time of day, p=0.144), indicating that MFO was higher in the afternoon than in the morning in both males (11.04 %) and females (38.82%). There was a significant time of day effect in Fatox rates, (p<0.0001, η2p = 0,81) and intensity (p=0.004, η2p = 0,469) that was independent of gender (time of day*intensity*gender interaction, p=0.0164) indicating that Fatox was higher in the afternoon than in the morning in both male and females
Conclusion: Our study extends previous findings on the existence of diurnal variation in maximal fat oxidation to MetS patients, highlighting the afternoon as a more favorable time for fat utilization during exercise, and shows that gender does not interfere with these diurnal variations as previously suggested. These findings have practical implications for optimizing training strategies in MetS patients. Further research is needed to delineate the discrepancy between gender and substrate oxidation patterns.

Efficient Demineralization and Desulfurization of Lignite Coal using Alkali and Alkali-Acid Follow up Treatments for Reduced Flue Gas Emissions and Enhanced Calorific Value: A Comparative Study
Authors: Lakhmir Mansoor Ahmed , Soomro Suahil Ahmed , Unar Imran Nazir 
Published: January 2024

Abstract
In world the largest reserves of low-grade coal or lignite coal are available. A low-ranking coal with high mineral content, sulfur, moisture and low calorific value greatly contribute to environmental pollution via emission of greenhouse gases, SOx and NOx. To resolve this, the coal must be extracted or reduced of its minerals and sulfur through the processes called demineralization and desulfurization. In this, the researchers have been unveiling new and efficient ways to treat coal for reduced air pollution during combustion. Herein, demineralization and desulfurization of coal were carried out using alkali and alkali-acid hybrid treatments. In the first method, the samples were treated solely with alkali while in the second, they were treated with acid followed by alkali. The coal samples were analyzed via SEM, TGA, XRD and FTIR; their chemical composition determined through ONH and SC analyzer. As per results, alkali-acid hybrid treatment was more efficient than just alkali treatment. The hybrid treatment of 100 g/L NaOH followed by 10% HCl exhibited higher porosity, thermal stability, demineralization of 90.9%, desulfurization of 63.46% and calorific value of 26585.924 KJ/Kg in the respective coal sample. On the other hand, alkali treatment with 100 g/L NaOH resulted in comparatively lower porosity, thermal stability, demineralization of 63.86%, desulfurization of 49.42% and calorific value of 23770.905 KJ/Kg respectively. When compared with 6 relevant studies, the coal sample with the least sulfur and mineral content in the present work indicated lowest impurities.
Design of Transmitter and Receiver to Achieve Ultra-reliability and Low Energy Communication
Authors: Nguyen Tien , Ta Hien , Oh Hoon 
Published: January 2024

Abstract
High reliability and low energy communication are the important requirements for future communication systems. Existing approaches mainly attempted to correct modulated signals using channel estimation or increase signal strength using diversity techniques; the former revealed its limitations in a fast-fading environment, and the latter conflicted with green communication. In our approach, the transmitter transmits a compound signal consisting of a modulated signal and a dummy signal with no bandwidth that belong to the coherence bandwidth. Since the two signals experience approximately the same distortion and noise, the receiver can use a differential operation to remove distortion and suppress background noise. This approach halves the strength of each signal but satisfies the requirements by significantly improving SNR. Experiments using two testbeds, a digital communication platform using FPGA, and a testbed using three WLAN devices, show that our method achieves significantly lower SNR than existing ones at the same BER.
Decadal changes in land use and land cover: impacts and their influence on urban ecosystem services

Published: January 2024

Abstract

The steady growth of cities alters the urban environmental pattern and functions, posing significant challenges to urban ecological as well as environmental governance. Under this setting, analyzing the relationship between urban growth and ecological services is critical for management and policy-related sustainable urban development. The primary goal of this research is to analyse the dynamic urbanization and its influence on urban ecosystem services via changes in LULC of Mangaluru city agglomeration, India. For five decades (1980,1990, 2000, 2010, and 2022), the ecosystem service values (ESVs) are analysed using remote sensing data and Geographic Information System (GIS) techniques corresponding with the global value coefficient (VC) to estimate total ecosystem service values (ESVt) and individual ecosystem service function change. The study shows that ecosystem service values (ESVs) declined by US$ 116.89 million to US$ 85.14 million due to 9.54 and 63.44% decreases in agricultural land and wasteland/shrubland between 1980 and 2022. In terms of individual ecosystem service functions, regulating services increased from 1980 to 2022, with nutrient cycling (45.64%), raw material (15.59%), and erosion control (12.13%) contributing the most. The loss in total and certain individual ESV in the study landscape necessitates immediate action to improve urban ecosystem sustainability via proper planning and policy.
