Applications of Carbon Fiber Instrumentation in Spinal Oncology: Recent Innovations in Spinal Instrumentation and 2-Dimensional Illustrative Operative Video
Authors: Oh Justin , Visco Zachary R. , Ojukwu Disep I. , Galgano Michael A. 
Published: January 2023

BACKGROUND:
The management of spinal oncology necessitates a multimodal approach, with surgical intervention, radiation-based therapy, and postoperative advanced imaging. These systems must work well together to provide optimal patient outcomes. Traditional metallic spinal implants produce image artifacts and lead to radiation dose attenuation, which inhibit both disease monitoring and disease treatment, respectively.

OBJECTIVE:
To demonstrate the feasibility of an improved biomaterial implant that provides structural stability, while also allowing for disease monitoring and treatment in spinal oncology patients.

METHODS:
From February 2021 to September 2021, 3 patients with spinal oncologic deformity requiring resection and posterior spinal stabilization underwent fixation with polyether ether ketone-carbon fiber implants at a single academic institution.

RESULTS:
Patient ages ranged from 23 to 74 years (mean: 44.7 years). All patients underwent posterior spinal fixation using standard approaches. They each received polyether ether ketone-carbon fiber pedicle screw and rod implants, placed in standard fashion. There were no dural tears, postoperative wound infections, or other complications related to their treatment. Postoperative surveillance revealed gross total resection of the targeted tumor on postoperative radiographic imaging.

CONCLUSION:
Polyether ether ketone-carbon fiber implants are a safe and effective option for the treatment of thoracolumbar posterior spinal pathology. The utilization of this novel type of instrumentation in posterior spinal approaches may provide benefit to patients with spinal tumors over existing forms of posterior spinal instrumentation.
Peak Cardiac Output Determined Using Inert Gas Rebreathing: A Comparison of Two Exercise Protocols
Authors: BOSTAD WILLIAM , MCCARTHY DEVIN G. , RICHARDS DOUGLAS L. , HELAL LUCAS , GIBALA MARTIN J. 
Published: January 2023

ABSTRACT
Peak cardiac output (Q˙
peak) can be measured noninvasively using inert gas rebreathing (IGR). There is no consensus on the optimal protocol to measure Q˙
peak using IGR, which requires a rebreathing period of ~10 s as close to “maximal” exercise as possible.

Purpose
This study aimed to compare Q˙
peak elicited by a constant load protocol (Q˙
CL) and an incremental step protocol (Q˙
step).

Methods
A noninferiority randomized crossover trial was used to compare Q˙
peak between protocols using a noninferiority margin of 0.5 L·min−1. Participants (n = 34 (19 female, 15 male); 25 ± 5 yr) performed two baseline V̇O2peak tests to determine peak heart rate (HRpeak) and peak work rate (W
peak). Participants then performed the Q˙
CL and Q˙
step protocols each on two separate occasions with the order of the four visits randomized. Q˙
peak was measured using IGR (Innocor; COSMED, Rome, Italy). The Q˙
CL protocol involved a V̇O2peak test followed 10 min later by cycling at 90% W
peak, with IGR initiated after 2 min. Q˙
step involved an incremental step test with IGR initiated when the participant’s HR reached 5 bpm below their HRpeak. The first Q˙
CL and Q˙
step tests were compared for noninferiority, and the second series of tests was used to measure repeatability (typical error (TE)).

Results
The Q˙
CL protocol was noninferior to Q˙
step (Q˙
CL = 17.1 ± 3.2, Q˙
step = 16.8 ± 3.1 L·min−1; 95% confidence intervals, −0.16 to 0.72 L·min−1). The baseline V̇O2peak (3.13 ± 0.83 L·min−1) was achieved during Q˙
CL (3.12 ± 0.72, P = 0.87) and Q˙
step (3.12 ± 0.80, P = 0.82). The TE values for Q˙
peak were 6.6% and 8.3% for Q˙
CL and Q˙
step, respectively.

Conclusions
The Q˙
CL protocol was noninferior to Q˙
step and may be more convenient because of the reduced time commitment to perform the measurement.

Abstract. Suharjono, Yuliatin E. 2022. Bacteria communities of coffee plant rhizosphere and their potency as plant growth promoting. Biodiversitas 23: 5822-5834. This study aimed to investigate the soil bacteria communities of the coffee rhizosphere and evaluate the potency in supporting coffee plant growth. The soil was collected from the Coffea canephora and Coffea arabica in Malang, East Java. The bacterial genomic DNA was extracted by FastDNA Spin kit while the Illumina platform analyzed the total gDNA. Other samples were isolated using the serial dilution method on Tryptic Soy Agar, Pikovskaya Agar, and Nitrogen-free-Bromothymol Blue Agar medium to isolate IAA-producing, phosphate-solubilizing, and nitrogen-fixing bacteria, respectively. The selected bacteria isolates were identified based on 16S rDNA sequencing. As a result, the Proteobacteria showed dominance at the phyla level, and Bradyrhizobium elkanii was the most abundant species with a not significant different proportion between Robusta and Arabica soil. The quantifying method of the selected isolate showed the maximum concentration, such as S1.6.3.2 isolate producing IAA-hormone at 104.46 µg/mL, W3.5 isolate solubilizing the phosphate at 4.5 µg/mL, and W1.2 isolate fixing the ammonia at 21.54 µg/mL. Those potential isolates, S1.6.3.2, W3.5, and W1.2, were identified as Bacillus subtilis DSM 10, Pseudomonas putida S18, and Bacillus methylotropicus SY2, respectively. Further research shows that those bacteria consortiums can be a candidate as biofertilizers due to helping soil health stimulation and promoting coffee growth.

Abstract. Suriya C, Satian C, Visut B, Supadha K. 2022. Diversity of freshwater fish at Sago Palm Wetlands, Nakhon Si Thammarat Province, Thailand. Biodiversitas 23: 6335-6344. Studies on the diversity of freshwater fish at Sago Palm Wetlands, Nakhon Si Thammarat Province, Thailand, were conducted in the period from March 2020 to November 2020. Fish samples were collected, encompassing the hot-dry season (March to June) and the rainy season (September to November) at 4 sampling zones, with 5 stations for each zone. Fish were caught using a seine net of 1 cm mesh size, 1.5m in length, and 1m in width. All data were analyzed to find out the fish diversity indices. The multivariate method was used to determine cluster analysis. A total of 3634 fish specimens, representing 62 species belonging to 24 families, were recorded during the sampling period. Cyprinidae was the major family, with Trichopsis vittatus containing the highest index of relative importance (IRI). The species diversity index of fish was in the range of 0.66 to 2.67; the evenness index was in the range of 0.64 to 0.95, and the species richness index ranged from 0.36 to 6.86, indicating an intermediate-low uniformity, with a medium species number in the area. The cluster analysis of the Bray-Curtis similarity index shows A division of the fish community into 2 clusters in the hot-dry season and 3 clusters in the rainy season, having a similarity percentage ranging between 42% and 95%, respectively. Also documented were one introduced species and one endangered fish species during sampling. The findings suggest that Sago Palm Wetlands is still inhabited by numerous fish species and should be conserved to ensure its aquatic animal richness for the future. This data provides information about the fish habitat in the Sago Palm Wetlands and can be used to update the checklists of fish species in the Tapi River, the Pak Phanang River, and the Trang River Basins. It also can be useful for the planning of fishing activities and the provision of guidelines for future research and conservation purposes.

Abstract. Ivayani, Widiastuti A, Suryanti, Suharjo R, Priyatmojo A. 2022. Short Communication: First report of Xanthomonas sacchari causing rice sheath rot disease in Lampung, Indonesia. Biodiversitas 23: 6463-6470. Rice sheath rot is recently reported as an emerging important rice disease in Indonesia, which can cause yield losses of up to 85%. Due to its potential loss, serious attention should be given on the disease. However, there is still limited information on the causal agent of the disease in Indonesia, especially from plant pathogenic bacteria. One bacterial isolate (LSE 33) was obtained from the sheath rot symptom of rice. Pathogenicity test revealed that bacteria produced symptoms that were similar to those obtained from the field. Based on the sequence analysis of 16S rRNA gene region, isolate LSE 33 was placed within group of the type strain and reference strains of Xanthomonas sacchari. Strain LSE 33 had 99.93% sequence similarity with Xanthomonas sacchari strain SAM 144 and strain AF 10 isolated from rice, and 99.35% similarity with strain LMG 471T isolated from sugarcane. To our knowledge, this is the first report of X. sacchari causing sheath rot on rice in Indonesia.
Efficient fabrication method for non-periodic microstructures using one-step two-photon lithography and a metal lift-off process

This paper presents a mask-less, flexible, efficient, and high-resolution fabrication method for non-periodic microstructures. Sub-wavelength micro-polarizer arrays, (MPAs) which are the most essential part of the focal plane polarimeters, are typical non-periodic structures. The grating ridges of each polarizer were oriented in four different directions offset by 45°, corresponding to different polarization directions. The finite element method was introduced to optimize the structural parameters of the MPA in the far-infrared region. The numerical results demonstrated that the designed MPA had a TM transmittance of more than 55% and an extinction ratio no less than 7 dB. An aluminum MPA that operates in the 8–14 µm infrared region was prepared by one-step two-photon lithography (TPL) and the metal lift-off process. The femtosecond laser exposed the photoresist with only a single scan, making TPL very efficient. The fabricated single-layer sub-wavelength MPAs with a period of 3 µm, a duty cycle of 0.35–0.5, and a height of 150 nm, were analyzed by an optical microscope and an atomic force microscope. The successful fabrication of the MPA indicated that one-step TPL could be a viable and efficient method for pattern preparation in the fabrication of non-periodic microstructures.

Normal group velocity dispersion (GVD) microcombs offer high comb line power and high pumping efficiency compared to bright pulse microcombs. The recent demonstration of normal GVD microcombs using CMOS foundry-produced microresonators is an important step toward scalable production. However, the chromatic dispersion of CMOS devices is large and impairs the generation of broadband microcombs. Here, we report the development of a microresonator in which GVD is reduced due to a coupled-ring resonator configuration. Operating in the turnkey self-injection locking mode, the resonator is integrated in a hybrid manner with a semiconductor laser pump to produce high-power efficiency combs spanning a bandwidth of 9.9 nm (1.22 THz) centered at 1560 nm, corresponding to 62 comb lines. Fast, linear optical sampling of the comb waveform is used to observe the rich set of near-zero GVD comb behaviors, including soliton molecules, switching waves (platicons), and their hybrids. Tuning of the 20 GHz repetition rate by electrical actuation enables servo locking to a microwave reference, which simultaneously stabilizes the comb repetition rate, offset frequency, and temporal waveform. This integrated hybrid system could be used in coherent communications or for ultrastable microwave signal generation by two-point optical frequency division.
Refractive changes after strabismus surgery in patients with intermittent exotropia
Authors: Moon Yeji , Kim Seong-Joon 
Published: January 2023

Objectives
To evaluate the long-term refractive changes after horizontal muscle surgery in patients with intermittent exotropia and investigate the correlation between changes in the postoperative refractive error and clinical factors.

Methods
We retrospectively reviewed the clinical data of patients aged < 15 years who underwent unilateral strabismus surgery (lateral rectus recession and medial rectus resection [RR, n = 47], lateral rectus recession and medial rectus plication [RP, n = 81], or lateral rectus recession [LRc, n = 68]). Preoperative and postoperative refractive errors up to four years after surgery were recorded. A mixed model was applied to compare the refractive error between the operated and fellow eyes and identify the factors associated with postoperative refractive changes.

Results
The mean age at surgery was 7.5±2.4years, and girls accounted for 56.1% of the study population. There was no significant difference in the change in the spherical equivalent of refractive error between both eyes throughout the postoperative period. In contrast, the operated eyes consistently and significantly showed higher cylindrical power in with-the-rule astigmatism by 0.25D than in fellow eyes. Age, sex, and preoperative refractive error were not correlated with changes in postoperative astigmatism. Meanwhile, the type of surgery showed a significant interaction with the astigmatism changes. RP had less effect on the changes in astigmatism than RR and LRc (p = 0.001 and p = 0.022, respectively).

Conclusions
Horizontal muscle surgery has no long-term effect on the change in the spherical equivalent. However, mild with-the-rule astigmatism is induced and sustained after surgery, and the type of surgery affects the postoperative change of astigmatism.

MAQASID SYARIAH DAN PENGARUH PELARANGAN BUNGA DALAM PEREKONOMIAN NASIONAL
Authors: Muhammad Baiquni Syihab  
Published: January 2023

Abstract
Bank interest as stated by MUI is usury, and usury is unlawful. However, bank interest cannot be released from the economic system because it functions as a financial instrument that regulates the money supply. Without interest, the banking operational system cannot run. Without service fees from the central bank, the banking operational system (both conventional and sharia) cannot function as it should. Maqasid sharia is the purpose and wisdom of establishing a law given by the Khaliq (Allah), then of course the forbidden law on the practice of muamalah flowering (usury) has a purpose and wisdom. And as revealed in the Qur'an that the prohibition of usury is intended so that humans are not wrongdoers who wronged and no one was wronged in terms of property. In this discussion we reveal, that the practice of bank interest is the main cause of inflation. Inflation itself means a decrease in the value of money, and not an increase in the price of goods. That is, it is possible that among the community there is absolutely no practice of usury, but still it has a bad impact, exposed to dirty splashes of usury practice. Namely, the wealth of money that he has has decreased in value due to inflation.

Abstract
The International Federation of Clinical Chemistry and Laboarator Medicine (IFCC) Committee on Clinical Applications of Cardiac Bio-Markers (C-CB) has provided evidence-based educational resources to aid and improve the understanding of important analytical and clinical aspects of cardiac biomarkers. The present IFCC C-CB educational report focuses on recommendations for appropriate use, analytical performance, and gaps in clinical studies related to the use of cardiac troponin (cTn) by point of care (POC) measurement, often referred to as a point of care testing (POCT). The use of high-sensitivity (hs)-cTn POC devices in accelerated diagnostic protocols used in emergency departments or outpatient clinics investigating acute coronary syndrome has the potential for improved efficacy, reduction of length of stay and reduced costs in the health care system. POCT workflow integration includes location of the instrument, assignment of collection and testing responsibility to (non-lab) staff, instrument maintenance, in-service and recurrent training, quality control, proficiency assessments, discrepant result trapping, and troubleshooting and inventory management.
The Impact of COVID-19 on World Oil Producers: Time is Important

Abstract
The COVID-19 crisis had a significant impact on world oil producers. Within a welfare economic framework, Schmitz, A., C. B. Moss, and T. G. Schmitz. 2020. “The Economic Effects of COVID-19 on the Producers of Ethanol, Corn, Gasoline, and Oil.” Journal of Agricultural & Food Industrial Organization 18 (2): 1–18, estimated that the minimum cost of COVID-19 in 2020 to world oil producers was roughly US$ 1 trillion. They used actual oil production data for January 1st, 2020, through June 30th, 2020, and forecast world oil production and prices from July 1st to December 31st, 2020. This paper extends the 2020 analysis using actual production and price data for 2020 and 2021 to calculate the change in producer economic rents during the COVID-19 pandemic for global oil producers (U.S., Russia, Saudi Arabia, and the Rest of the World). Despite losses in 2020 to world oil producers due to the COVID-19 pandemic, world oil producers saw significant gains in 2021, which more than offset losses in 2020. At a minimum, world oil producers realized a net gain of $US 829 billion over the two periods.
An Unpublished Letter by A. E. Housman Related to the Textual Criticism of Statius’ Siluae
Authors: Shumilin Mikhail 
Published: January 2023

Abstract
The article presents an edition of the previously unpublished letter from A. E. Housman to Grigory E. Saenger, written in Latin and dated 28 May, 1909, as well as a commentary on this text. The letter contains a criticism of Saenger’s 1909 edition of Statius’ Siluae. Housman evaluates the general approach of the edition and pronounces his judgement on two particular decisions made by the editor. The commentary treats both the general context of the letter and particular statements made by Housman. The approach recommended by Housman is compared to those adopted in the major post-Saengerian editions of the Siluae; it is suggested that, while in certain respects some of the modern editions come close to what Housman endorsed, in other ways there is nothing among them to compare with it.
