Authors: Beaty William , Katragadda Anila , Condos Rany , Dane Bari , Sarkar Suparna , Shaffer Emily , Chang Shannon 
Published: January 2024

ABSTRACT
Although extraintestinal manifestations of inflammatory bowel disease (IBD) are common, pulmonary IBD is extremely rare. Owing to its nonspecific clinical, radiologic, and pathologic features, pulmonary IBD is difficult to diagnose and may mimic more concerning disease processes. We present a rare case of a patient with known Crohn's disease whose initial presentation was highly suspicious for malignancy before further investigation revealed pulmonary IBD.

Published: January 2024

ABSTRACT
This case report highlights the challenge of differentiating between immunoglobulin G4 (IgG4)-related disease (IGRD) and liposarcoma, which have similar symptoms and serological markers. A 40-year-old woman presented with right upper-quadrant pain and a retroperitoneal mass. Initial biopsy indicated increased IgG4-positive cells, leading to an IGRD diagnosis. However, the mass grew, despite prednisone treatment, prompting a repeat biopsy that revealed well-differentiated liposarcoma. Liposarcoma should be considered in patients with retroperitoneal masses and elevated IgG4 levels. Surgical resection is the primary treatment, emphasizing the need for early identification and close monitoring. Confirming IGRD or ruling out other diagnoses through histopathologic analysis is vital.

Published: January 2024

A sequência de Mersenne, batizada em homenagem ao matemático francês Marin Mersenne, é uma progressão recursiva de segunda ordem representada por um modelo unidimensional, cujos números podem ser expressos na forma Mn = 2n-1. Esta pesquisa tem como objetivo explorar e investigar as relações recorrentes em diferentes dimensões, incluindo as bidimensionais (M(n,m)), tridimensionais (M(n,m,p)) e n-dimensionais (M(n1,n2,n3, ... , nt)) . O modelo unidimensional utilizado é definido pela recorrência Mn+1 = 3Mn - 2Mn-1, onde n é um número inteiro não negativo, e os valores iniciais são estabelecidos como M0 = 0 e M1 = 1. A pesquisa examina a evolução da sequência e seu processo de complexificação. Durante essa análise, são identificadas propriedades matemáticas das relações desses números, enfatizando o aumento dimensional da sequência e a introdução de unidades imaginárias i, j, ... , µn. Isso culmina na generalização das relações n-dimensionais, proporcionando uma compreensão mais abrangente e profunda da sequência de Mersenne.

Published: January 2024

Em 2018, o IBGE alinha-se às recomendações internacionais determinando as chamadas altitudes normais. Em razão disso, criou-se a necessidade de modelar a Separação entre Geoide e Quase Geoide (SGQG) para permitir a conversão entre altitudes normais e ortométricas para os países que optarem por utilizar-se desta última. Esse estudo se propõe avaliar o valor da SGQG a partir das diferenças entre as altitudes ortométrica e normal. Para o desenvolvimento deste estudo foram utilizados: dados altimétricos e dados gravimétricos; mapa de densidades das massas topográficas derivadas a partir do mapa geológico; bem como os coeficientes do Modelo Global do Geopotencial EGM2008. A metodologia consiste em calcular e avaliar a altitude ortométrica obtida a partir do número geopotencial, com o valor da densidade topográfica lateral constante e variável; determinar a SGQG a partir da diferença entre as altitudes ortométrica e normal, e verificar as discrepâncias em relação a SGQG obtida a partir da diferença entre a anomalia de altitude e da ondulação geoidal do modelo EGM2008. Os resultados mostram que a SGQG apresenta uma variação entre cm a 10 cm, sendo que as discrepâncias maiores são observadas no município de São José dos Ausentes e adjacências. A negligência da omissão dos efeitos da densidade topográfica lateral na determinação da altitude ortométrica foi estimada em 2 cm. Os resultados mostraram a necessidade da efetiva incorporação das variações das densidades das massas topográficas aos cálculos da SGQG, quando se almeja a determinação das altitudes ortométricas.

Abstract

Objectives
The current study was designed to evaluate the analytical performance of the new Mindray highly sensitive cardiac troponin I (hs-cTnI) chemiluminescent immunoassay on Mindray CL-1200i, as a thorough validation of novel hs-cTnI methods is required before introduction into clinical practice.

Methods
The evaluation of the analytical performance of this hs-cTnI immunoassay encompassed the calculation of the limit of blank (LOB), limit of detection (LOD), functional sensitivity, imprecision, linearity, 99th percentile upper reference limit (URL) and concordance with another previously validated hs-cTnI chemiluminescent immunoassay.

Results
The LOB and LOD were 0.32 and 0.35 ng/L, whilst the functional sensitivity (expressed as cTnI value with <10 % imprecision), was 0.35 ng/L. The linearity was excellent throughout a wide range of clinically measurable values (r=1.00 between 0.8 and 9,726.9 ng/mL). The intra-assay, inter-assay and total imprecision were 1.1–1.3 %, 5.5–8.1 % and 5.6–8.2 %, respectively. The 99th percentile URL calculated using residual plasma from 246 ostensibly healthy blood donors was 9.2 ng/L (4.3 ng/L in women vs. 12.3 ng/L in men). The Spearman’s correlation between Mindray hs-cTnI and Access hs-TnI was 0.97, with mean bias of 7.2 % (95 % CI, 2.6–11.9 %).

Conclusions
Although we failed to confirm the very optimistic analytical characteristics previously reported for this method, our evaluation of the novel Mindray hs-cTnI immunoassay on CL-1200i demonstrated that the overall performance is comparable to that of other commercially available hs-cTnI techniques, making it a viable alternative to other methods.
Corrosion of stainless steels and corrosion protection strategies in the semiconductor manufacturing industry: a review
Authors: Ma Chaoran , Du Zhuoyang , Wang Xiaohan , Zhou Peng , Zhao Yang , Hua Yong , Su Cheng , Zhang Tao , Wang Fuhui 
Published: January 2024

Abstract
Stainless steels are used extensively in semiconductor manufacturing as chamber, structure component and gas delivery systems. The corrosion in the aggressive gas in the semiconductor manufacturing industry leads to particle release, contaminating wafers and limiting their application. Moisture content can accelerate the corrosion rate of stainless steel. In a high-temperature environment, the corrosion is determined by the synergistic effect of the vapour of the corrosion product and thermal ageing. To eliminate corrosion, lots of efforts have been performed and categorized into three aspects: (1) Material purification using innovating metallurgy techniques, especially vacuum induction melting (VIM) and vacuum arc remelting (VAR). The ultra-pure stainless steel minimizes the inclusion in stainless steel, suppressing the breakdown of the passive film. (2) Smoothing the surface by polishing; the polishing surface shows hydrophobic behaviour and decreases moisture absorption. (3) Applying surface and coating techniques against corrosion, including passivation treatment and electroplating/electroless Ni-based coating. Herein, the techniques mentioned above are reviewed, and the prospect and development of stainless steel in the semiconductor manufacturing industry are forecasted.

AbstractIn this research, cell-free extracts from magnesite mine-isolated actinobacterial strain (M10A62) were used to produce silver sulfide nanoparticles (Ag2SNPs).Streptomyces minutiscleroticusJX905302, actinobacteria capable of producing Ag2SNPs, was used to synthesize Ag2NPs. The UV–vis range was used to confirm the biosynthesized Ag2NPs; Fourier transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDAX), and dynamic light scattering analysis were employed to characterize them further. Surface resonance plasma (SRP) for Ag2SNPs was obtained at 355 nm using UV–visible spectroscopy; FT-IR detected bimolecular and eventually microbial-reduced Ag2SNPs fromS. minutiscleroticusculture extract. Furthermore, AFM and TEM analysis confirms that the synthesized Ag2SNPs were spherical in shape. Dynamic light scattering revealed a negatively charged Ag2NPs surface with a diameter of 10 nm. The XRD spectrum showed the crystalline nature of the obtained particles. EDAX revealed a pure crystalline nature, and a significant silver particle signal confirms the presence of metallic silver and sulfide nanoparticles together with the signals of Cu and C atoms. After 40 and 48 h of treatment at 150–200 µg·ml−1, Ag2SNPs produced the highest mortality inSpodoptera litura,H. armigera, Aedes aegypti, andCulex quinquefasciatuslarvae. Hence, the biosynthesized Ag2SNPs may be useful for potential pest control in integrated pest management and vector control program as a safer, cost-effective, selective, and environmentally friendly approaches.

Published: January 2024

Abstract
The establishment of fast-growing teak plantations in Indonesia provides opportunities for shorter harvesting periods. However, it also poses challenges on wood utilization due to juvenility and growth stress-related defects. This study investigated growth stress levels and some wood properties of 10-year-old fast-growing teak grown in Gunungkidul Regency, Yogyakarta. The strain gauge method was used to measure longitudinal surface released-strains (LRS), tangential surface released-strains (TRS), and longitudinal internal residual strains (IRS). Wood specimens were also collected near each strain measurement point for the analysis of wood properties. The results showed LRS values ranging from −1243 to 320 με, TRS values ranging from −779 to 382 με, and IRS values ranging from −589 to 786 με. Meanwhile, radial variations in fiber length, modulus of elasticity, and lignin content were observed. Significant correlations were found between IRS values and microfibril angle, fiber length, modulus of elasticity, lignin content, and hemicellulose content, while no significant correlations were observed between LRS and TRS values and wood properties. These findings suggest a moderate level of growth stress. Additionally, the results also indicate that this 10-year-old fast-growing teak is still in the juvenile stage. Therefore, its utilization should be performed with caution.

Published: January 2024

Abstract

Context
Medical school graduates are generally not well prepared to treat patients with substance use disorders (SUDs), even though opioid overdose deaths in the United States have increased in recent years. When it comes to training in SUDs, osteopathic medicine lags far behind allopathic medicine. It was only in 2019 that the American Osteopathic Association approved Board Certification in Addiction Medicine to help combat the opioid epidemic. Few articles have been published in the literature pertaining to substance use education for osteopathic students and trainees.

Objectives
The goal of this study was to expand the education of osteopathic medical students and primary care residents in SUDs and measure the effect that education had on the attitudes and knowledge of student and residents about SUDs.

Methods
This study collected anonymous data in the form of a voluntary online survey from third- and fourth-year students at an osteopathic medical school and family medicine residents. The survey was completed by 115 students and 29 family medicine residents. Participants completed a pretest survey and then participated in the Physician Undergraduate and Resident Substance Use Education (PURSUE) curriculum developed by the researchers. This consisted of three online modules covering Screening, Brief Intervention, and Referral to Treatment (SBIRT), substance use assessments, and treatment of SUDs. Upon conclusion of the training modules, medical student participants then completed a posttest survey to assess for any changes in knowledge and attitude. Participants also answered questions related to clinical case scenarios involving patients at varying risk levels who were assessed utilizing SBIRT.

Results
Students and residents who participated in the training demonstrated an increase in their average scores between the pretest and posttest, indicating effectiveness in learning from the modules. The overall increase in average scores on the pretest and posttest was 6.5 %, which was determined to be statistically significant (p<0.01). Interestingly, participants who reported growing up in underprivileged circumstances performed worse than those participants who reported not growing up in underprivileged circumstances.

Conclusions
The results of our project support the need and benefit of incorporating educational modules on this topic area within medical school curriculums and residency training. Expanding the number of healthcare workers proficient in providing this type of care in these types of settings will improve the quality of and access to medical care in some of our highest-need populations.

Published: January 2024

Abstract

Objectives
Adrenocorticotropic hormone (ACTH) is extremely unstable and can easily degrade at room temperature. The experts agreed that the samples should be transported in an ice bath. If it cannot be detected immediately, the plasma should be separated and frozen, which is difficult to carry out in routine practice. This study was performed to explore the preanalytical factors that influence the stability of adrenocorticotrophic hormone (ACTH) measurements.

Methods
ACTH levels in 21 EDTA whole-blood samples were measured immediately after 0 h and then divided into three equal groups according to the corresponding values (low, L; median, M; and high, H). Next, three sample processing methods (including seven subtypes) were used: whole blood was uncentrifuged (named the A method), stored at 4 °C or 22 °C, centrifuged but not subjected to plasma removal (the B method), stored at 4 °C or 22 °C, and centrifuged with the plasma removed and stored (the C method) at 4 °C, 22 °C, and −20 °C. Each subtype contained three samples, namely, L, M, and H; these samples were retested using a Siemens XP2000 at different times. The change bias was calculated at 0 h.

Results
Compared to that at 0 h, there was no significant change in ACTH up to 24 h when the sample was stored at 4 °C or 22 °C with the B method (p>0.05), while it significantly changed (up or down >10 %) at 4 °C/24 h (bias is expressed as the mean±SEM; 13.37±21 %, p<0.05) and 22 °C/12 h (9.13±7.68 %, p<0.05) with the A method; and 4 °C/24 h (8.93±5.54 %, p<0.05), 22 °C/12 h (9.5±4.47 %, p<0.05) and −20 °C/3 h (12.03±4.8 %, p<0.05) with the C method.

Conclusions
After ACTH samples were centrifuged, the presence of plasma without removal did not affect the detection value, and the sample was stored at 4 °C for up to 24 h. There was a significant difference in the detection of ATCH when the sample was stored at −20 °C and thawed again (p<0.05).

Abstract
The short exciton diffusion length in organic semiconductors results in a strong dependence of the conversion efficiency of organic photovoltaic (OPV) cells on the morphology of the donor-acceptor bulk-heterojunction blend. Strong light–matter coupling provides a way to circumvent this dependence by combining the favorable properties of light and matter via the formation of hybrid exciton–polaritons. By strongly coupling excitons in P3HT-C60 OPV cells to Fabry–Perot optical cavity modes, exciton-polaritons are formed with increased propagation lengths. We exploit these exciton–polaritons to enhance the internal quantum efficiency of the cells, determined from the external quantum efficiency and the absorptance. Additionally, we find a consistent decrease in the Urbach energy for the strongly coupled cells, which indicates the reduction of energetic disorder due to the delocalization of exciton–polaritons in the optical cavity.
