Published: March 2022

BackgroundThe present study analyzes diagnostic and therapeutic surgical aspects of primary small bowel melanoma, describing the clinical case and reviewing the literature. Malignant melanomas represent 1–3% of all malignant tumors of the gastrointestinal tract and are therefore uncommon. Only a few cases of metastatic melanoma (1–5%) are diagnosed in the early stages, while still asymptomatic. They show up as imaging exam findings and have better chance of treatment. Most of the time, the diagnosis is late and made in the presence of complications. The final diagnosis frequently depends on the surgical intervention after a serious complication.Case reportThis case report refers to a 55-year-old male patient, complaining of abdominal pain, blackened stools, and palpable tumor in the abdomen for ~30 days. A tomography scan was performed, which revealed the thickening and parietal enhancement of the small intestine loops with mesenteric adenomegaly and intermingled collection. For diagnostic confirmation, a laparoscopy was performed, which revealed a tumor at the jejunal level, and its resection was performed in the same act. The anatomopathological examination revealed that it was a primary small bowel melanoma.ConclusionThe bibliographic research of the small bowel melanoma demonstrated that, in this situation, the lesion can be interpreted as a primary site or metastatic lesion, considering the possibility of a single primary lesion, whose diagnosis becomes more laborious. In such cases, adjuvant therapy must be considered. The expected 5-year survival is about 9–13%.

Lead is one of the most harmful toxic metals to humans. In Mexico, though most potters still use a lead-based glazing process, a new lead-free glaze has been introduced to the production of pottery. The Approved Pottery Program (APP) promotes the production of lead-free pottery. As a component of the APP, we aimed to document in this pilot study the blood lead levels (BLLs) of a sample of potters and the association with the type of glaze used. A cross-sectional study was conducted based on information from 46 potters grouped by 26 workshops. We measured general sociodemographic characteristics, capillary BLLs, and the lead levels of the dirt floors of the workshops. The evaluation of associations and comparisons between glaze types was performed based on a regression model clustered by workshop. The median BLL measured was 13.6 μg/dl (IQR: 7.8–20.4 μg/dl), and 70% of the BLLs were greater than 10 μg/dl. Workshop managers presented higher BLLs compared to others working in the same workshop (median of 14.1 μg/dl (IQR: 11.6–25.3 μg/dl) versus 10.1 μg/dl (IQR: 5.2–16.7 μg/dl), respectively). The median BLLs of potters who used lead-free glaze in at least 80% of production were 8.8 μg/dl (95% CI: −17.3 to −0.3 μg/dl) lower than the BLLs of those who used lead-free glaze in less than 30% of production, adjusted by workshop role. Additionally, the lead levels were significantly lower in workshop dirt floors where lead-free glaze was used in at least 80% of the production compared to those that use less than 30% (180 versus 916 mg/kg; p &lt; 0.05). The use of lead-free glaze in the production of pottery was associated with both lower BLLs in potters and lower soil lead levels in the workshop area.

Published: March 2022

Objective: The study investigates the magnitude and correlates of non-communicable disease multimorbidity and explores its linkages with health care utilization and out-of-pocket expenditure among aboriginal or tribal older adults.Methods: The study employed data on 11,365 older adults from Scheduled Tribes from the Longitudinal Ageing Study in India, 2017-18. A disease score was computed integrating sixteen non-communicable diseases. Descriptive, bivariate, and multivariable analyses were performed to identify the magnitude and correlates of multimorbidity. The study further explored the linkages between selected diseases and multimorbidity with health care utilization and expenditure.Results: The findings suggest that 27.1 and 14.5% of the aboriginal population lived with single or multiple disease, respectively. Hypertension and gastrointestinal disorders were frequent diseases. Higher age, Muslim religion, higher education, unemployment, and affluent background were the major correlates of multimorbidity. Health care utilization, mean expenditure on hospitalization, and outpatient visits increased significantly with multimorbidity.Conclusion: Multimorbidity is emerging as a health care challenge among the aboriginal population. Measures need to be taken to assess the multimorbidity burden and reduce health care expenditure, ensuring health equity among country’s vulnerable population.

Dysidazirine carboxylic acid (1) was isolated from the lipophilic extract of a collection of the benthic marine cyanobacterium Caldora sp. from reefs near Fort Lauderdale, Florida. The planar structure of this new compound was determined by spectroscopic methods and comparisons between HRMS and NMR data with its reported methyl ester. The absolute configuration of the single chiral center was determined by the conversion of 1 to the methyl ester and the comparison of its specific rotation data with the two known methyl ester isomers, 2 and 3. Molecular sequencing with 16S rDNA indicated that this cyanobacterium differs from Caldora penicillata (Oscillatoriales) and represents a previously undocumented and novel Caldora species. Dysidazirine (2) showed weak cytotoxicity against HCT116 colorectal cancer cells (IC50 9.1 µM), while dysidazirine carboxylic acid (1) was non-cytotoxic. Similar cell viability patterns were observed in RAW264.7 cells with dysidazirine only (2), displaying cytotoxicity at the highest concentration tested (50 µM). The non-cytotoxic dysidazirine carboxylic acid (1) demonstrated anti-inflammatory activity in RAW264.7 cells stimulated with LPS. After 24 h, 1 inhibited the production of NO by almost 50% at 50 µM, without inducing cytotoxicity. Compound 1 rapidly decreased gene expression of the pro-inflammatory gene iNOS after 3 h post-LPS treatment and in a dose-dependent manner (IC50 ~1 µM); the downregulation of iNOS persisted at least until 12 h.

Prescriptive learning is gradually gaining the attention of various industries in Nigeria, particularly on the issues and concerns surrounding sustainability. The existing literature shows that Nigerian pharmaceutical firms have not provided adequately researched prescriptive learning opportunities and sustainable employee engagement. Thus, this study explores the influence of prescriptive learning and sustainable employee engagement in selected pharmaceutical firms in Nigeria. Five hundred and forty-one (541) respondents were surveyed across all the selected pharmaceutical companies in Nigeria using a stratified and purposive sampling technique. Only four hundred and thirty-four (434) copies of the questionnaire, which represents an 80.2% rate of response. were analysed with Smart PLS 3.0. The results show that competitive differentiation, reflection, research and idea testing significantly influenced employee (cognitive, behavioral and affective) engagements. The study concludes that the adoption of prescriptive learning motivates sustainable employee engagement because employees become emotionally invested in work roles and functions. This study contributes to the strategic learning and development of human resource management practices, especially in the Pharmaceutical industry.

Implementation of Curriculum 2013 through Best Practice
Authors: Jumadi Jumadi 
Published: March 2022

The Curriculum 2013 will soon be implemented in all education units in the 2016/2017 school year, after going through a fairly tough process in the 2013/2014, 2014/2015 and 2015/2016 academic years so that it is only applied in a limited manner to a few educational units. Technical matters in the curriculum are indeed important for the successful implementation of education. However, there is one thing that should not be forgotten, namely how the teacher's creative process is in finding the best learning practices based on the experiences and practices that he has applied when teaching. The various ways and methods that have been applied by the teacher in teaching have made the teacher find new methods which are a Best Practice in teaching.
The formulation of best practices in the context of implementing the Curriculum 2013 is carried out through various approaches, namely: 1) Building a learning culture in schools. 2) Using a scientific approach with various types of active learning activities. 3) Relying on the skills of teachers in carrying out active learning in schools. 4) Changing aspects of attitudes, interest in learning, thinking skills, and ways of mastering learning concepts according to the best practice matrix in the context of implementing the 2013 Curriculum that has been formulated in this paper.
The steps to get best practice can be done by following the steps as follows: 1) Observing the situation; 2) Motivation; 3) Measurement of results and impacts; 4) Sustainable; 5) Experience that needs to be learned (lessons learned) and (action plan); 6) Potential for development; and 7) Comparative Study.
Effect of additive metal salt on ionic liquid/Li4Ti5O12 electrode interfaces investigated by atomic force microscopy
Authors: Bao Yifan , Kitta Mitsunori , Ichii Takashi , Utsunomiya Toru , Sugimura Hiroyuki 
Published: March 2022

Abstract
Ionic liquids (ILs) form layered solvation structures at IL/electrode interfaces relevant to many electrochemical applications. Recently, we observed a partially disturbed solvation structure at the 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMI-TFSI)/spinel lithium titanate oxide (Li4Ti5O12, LTO) electrode interface containing Li-salt and considered the Li+-ion transfer occurring at the interface as one plausible reason for this partial destruction. In this study, we investigated EMI-TFSI/LTO(111) interfaces with the addition of K-salt or Mg-salt by frequency modulation atomic force microscopy utilizing a quartz tuning fork. It is assumed that no ion-transfer occurs at these two interfaces. The laterally consecutive solvation structures were observed at both interfaces, which strongly supported our hypothesis. Additionally, a kink in the solvation structure was observed at the interface containing Mg-salt. These results offer a comprehensive understanding of the perplexing IL/electrode interfaces with an addition of metal salt.

Published: March 2022

Abstract
A one-dimensional focusing grating coupler array based in silicon nitride (SiN) was proposed for trapped ion qubit manipulation. By applying inverse design optimization with a double-etched grating structure, a directionality of 98% was achieved. A small beam diameter of 2.5 μm on the target ion with a low crosstalk of −36 dB was attained. Additionally, the impact of fabrication errors was investigated through a Monte Carlo simulation; within the accuracy of an electron beam lithography-based process, the output efficiency was maintained at 93%.

Published: March 2022

Abstract
We investigated the formation of periodic nanostructures on GaN induced by circularly-polarized femtosecond laser pulses. The structure shape changed from spiral to dots structures with increasing the pulse number. The structure change explained the previous inconsistent results, and we suggest a hypothesis for the formation dynamics. The period of the dots structures was approximately 150 nm which is almost 1/7 of the laser wavelength, and it kept crystalline comparable to the original substrate. The laser-induced periodic surface structures are expected to apply as a new fine processing technology.

0) (a-face) MOS devices were systematically investigated. Although NO nitridation is effective in improving the interface properties, we found that it reduces the onset field of Fowler–Nordheim current by about 1 MV cm−1, leading to pronounced leakage current. Synchrotron radiation X-ray photoelectron spectroscopy revealed that the nitridation reduces the conduction band offset at the SiO2/SiC interface, corroborating the above finding. Furthermore, systematical positive and negative bias stress tests clearly indicated the enhancement of V
FB instability of nitrided a-face MOS devices against electron and hole injection.
