Published: June 2024

The study examined the effect of exchange rate on goods and services in Nigeria with the objectives to analyze the effect of exchange rate fluctuations on prices of domestic goods and to investigate the extent to which exchange rate change has affected the prices of imported goods and services. The primary data were collected through the administration of questionnaire to the respondents. It was found out that the exchange rate has a significant effect on the prices of domestic goods and services as the coefficient of the independent variable is positive showing 0.628; it was established that the exchange rate has an effect on the prices of imported goods and services, as the coefficient of the independent variable is positive (0.428) and the sig value is less than 0.01. It was recommended that the government should fund all the micro, small, and medium scale enterprises in Nigeria through the Bank of Industry in order to have more exports than imports.

Healthcare resource utilization among nursing home residents with Parkinson's disease psychosis: an analysis of Medicare beneficiaries treated with pimavanserin or other-atypical antipsychotics
Authors: Rajagopalan Krithika , Rashid Nazia , Gopal Daksha , Doshi Dilesh 
Published: June 2024

Aim:
Real-world healthcare resource use (HCRU) burden among patients with Parkinson's disease psychosis (PDP) treated with pimavanserin (PIM) versus other atypical antipsychotics (other-AAPs) including quetiapine (QUE) in long term care (LTC) and nursing home (NH) settings are lacking. This analysis examines HCRU differences among residents in LTC/NH settings who initiate PIM versus QUE or other-AAPs.
Methods:
A retrospective analysis of LTC/NH residents with PDP from the 100% Medicare claims between 1 April 2015 and 31 December 2021 was conducted. Treatment-naive residents who initiated ≥6 months continuous monotherapy with PIM or QUE or other-AAPs between 04/01/16 and 06/30/2021 were propensity score matched (PSM) 1:1 using 31 variables (age, sex, race, region and 27 Elixhauser comorbidity characteristics). Post-index (i.e., 6 months) HCRU outcomes included: proportion of residents with ≥1 all-cause inpatient (IP) hospitalizations and emergency room (ER) visits. HCRU differences were assessed via log binomial regression and reported as relative risk ratios (RR) and 95% confidence intervals after controlling for dementia, insomnia and index year.
Results:
From a total of PIM (n = 1827), QUE (n = 7770) or other-AAPs (n = 9557), 1:1 matched sample (n = 1827) in each cohort were selected. All-cause IP hospitalizations (PIM [29.8%]) versus QUE [36.7%]) and ER visits (PIM [47.3%] versus QUE [55.8%]), respectively, were significantly lower for PIM. PIM versus QUE cohort also had significantly lower RR for all-cause IP hospitalizations and ER visits, respectively, (IP hospitalizations RR: 0.82 [0.75. 0.9]; ER visits RR: 0.85 [0.8. 0.9]). PIM versus other-AAPs also had lower likelihood of HCRU outcomes.
Conclusion:
In this analysis, LTC/NH residents on PIM monotherapy (versus QUE) had a lower likelihood of all-cause hospitalizations (18%) and ER (15%) visits. In this setting, PIM also had lower likelihood of all-cause HCRU versus other-AAPs.

Classification of organoid transcriptomic profiles unravelling colorectal cancer molecular subtypes
Authors:   , Nuwongsri Pattarin 
Published: June 2024

Colorectal cancer (CRC) is genetically and transcriptomically heterogeneous disease. Molecular subtyping of colorectal cancer using consensus molecular subtype (CMS) system demonstrated the potential predictive value for tumor progression and treatment response. However, the CMS system was developed from data of whole tissues containing both cancer and non-tumor transcripts components for classification which does not directly represent intrinsic heterogeneity of cancer cells. In this study genetic profiles of CRC organoids were investigated first, and the results indicate chromosomal instability (CIN) and microsatellite instability (MSI) as pathogenic pathways of CRC. Furthermore, the results also revealed diverse patterns of somatic mutations of these CRC organoids. Subsequently, we evaluated a strategy of subtyping CRCs based on transcriptomics data from patient-derived CRC organoids, which mainly contain cancer cells. We demonstrated that using non-negative matrix factorization (NMF) CRC cancer organoids could be classified into four groups (P1-P4). Cluster-specific genes and Gene Set Enrichment Analysis (GSEA) displayed different characteristics of each group. P1 exhibit enriched lipid and cholesterol metabolism pathways and P2 and P3 presented high TGF-β pathway. Lastly, P4 show stem cell-like properties and highly expressed genes in the DNA repair pathway associated with chemotherapy and radiation resistance. Moreover, P4 organoids present a hyperactivated ribosome biogenesis pathway which may be developed as a biomarker of P4 and a target of CRC treatment. Then, LASSO logistic regression was built to identify gene signatures and developed a classifier of each group of organoids. These results suggested that the signature gene of organoid groups has the potential to be developed into a useful tool for CRC subtyping and developing more specific therapeutic strategies.

Epigenetic regulation of leucine rich repeat containing G protein coupled receptor 5 (LGR5) in corneal endothelial cells
Authors:   , Prakanrattana Kulsiri 
Published: June 2024

Human corneal endothelial cells (hCECs) are vital for maintaining corneal transparency. However, their limited capacity for proliferation can result in vision loss, requiring corneal transplantation. The Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) plays a critical role in maintaining various fetal and adult stem cell types by promoting the Wnt/β-catenin signaling. Although LGR5 is present in corneal endothelial progenitors, its expression decreases as these cells mature, coinciding with the loss of replicative properties. In this study, we explore strategies to reactivate LGR5 expression in cultured hCECs through epigenetic modulation. We found low levels of DNA methylation and hydroxymethylation at LGR5 promoter in cultured hCECs. Our findings reveal that high-dose HDAC inhibitors, trichostatin A, and valproic acid enhanced LGR5 expression in cultured hCECs. In addition, combining low-dose valproic acid with small molecules including Wnt3A, R-Spondin1, and BMP inhibitors also promoted LGR5 expression in these cells. Furthermore, we generated CRISPRa targeting at LGR5 promoter which could activate LGR5 expression in HEK293 cells, especially with multiple sgRNAs. Applying this method to cultured hCECs can also specifically enhance LGR5 expression. Our results suggest that epigenome modification is a viable strategy for promoting corneal endothelium regeneration.
Massera type theorems for abstract non-autonomous evolution equations
Authors: Zheng Lan-Ling , Ding Hui-Sheng 
Published: June 2024

We establish two fixed point theorems for affine maps in Banach spaces, with weaker assumptions than those in the literature. Then we establish some Massera type results for abstract linear evolution equations without assuming the existence of bounded solutions, which is an indispensable condition in the classical Massera theorem and in the earlier literature. As application, we present an existence result on periodic mild solutions to abstract nonautonomous semilinear evolution equations.

Influence of Servant Leadership, Self Awareness, and Workload on Organizational Citizenship Behavior (OCB) and Employee Performance at BAPPEDA East Java Province
Authors: Patria Rio , Riyadi Slamet , Sumiati  
Published: June 2024

This study aims to examine the influence of Servant Leadership, Self Awareness, Workload on Organizational Citizenship Behavior (OCB), and Employee Performance at Badan Perencanaan Pembanguna Daerah (BAPPEDA) Provinsi Jawa Timur. The research was conducted using a quantitative approach and data were collected from employees working at BAPPEDA Provinsi Jawa Timur. The collected data is analyzed using the Structural Equation Modeling (SEM) PLS method with the Smart PLS Version 4.0 software. The respondents for this study were 118 employees out of a total of 137 employees at BAPPEDA Provinsi Jawa Timur. The data collection instrument was measured using a Likert scale. The research findings indicate that Servant Leadership significantly influences OCB but does not significantly affect Employee Performance. On the other hand, Self Awareness significantly influences both OCB and Employee Performance, while Workload does not significantly affect OCB but has a significant impact on Employee Performance. Additionally, OCB significantly influences Employee Performance. These results highlight the importance of implementing Servant Leadership and fostering Self Awareness to encourage OCB, while Workload has a greater impact on employee performance. Interestingly, the implementation of servant leadership does not seem to drive employee performance at BAPPEDA Provinsi Jawa Timur, however the high level of OCB in BAPPEDA of East Java Province can enhance employee performance.

Valuation K-Nearest Neighbors and Naïve Bayes for Dringking Water Potability Classification
Authors: Anisa Rahmawati  , Muhamad Fatchan  , Wahyu Hadikristanto  
Published: June 2024

The availability of drinking water that is safe and suitable for consumption is important to support health and development. This research emphasises the importance of handling the clean water crisis through the evaluation of drinking water quality using data mining algorithms. The dringking water quality evaluation method was selected using the K-Nearest Neighbors and Naive Bayes algorithms, replacing the manual method which is less responsive in predicting. The experimental process was conducted by utilising Kaggle website data by applying data processing and oversampling techniques to handle class imbalance in the dataset used. Bases on the research results, the accurancy of the K-Nearest Neighbors Algorithm reaches 65%, which is higher than the accuracy od the Naive Bayes Algorithm which is 64%. So it can be concluded that the K-Nearest Neighbors Algorithm is more effective in predicting the quality of water suitable for consumption. This research provides an in-depth insight into the use of technology and data analysis in dealing with the crisis in the availability of water suitable for consumption and offers suggestions for further research using more diverse methods and the use of more datasets to improve accuracy in evaluating the quality of potable water.

Published: June 2024

The purple corn plant has many benefits for body health so it is necessary to develop research related to this plant. This research aims to obtain information on the effect of giving Trichokompos on the production of purple corn plants as well as the recommended dosage of Trichokompos fertilizer based on research results. The design method used was Randomized Block Design with treatment in the form of different doses of Trichokompos fertilizer (0 tons/ha, 20 tons/ha, 25 tons/ha, 30 tons/ha, and 35 tons/ha). Analysis of variance and the Least Significant Difference (LSD) test showed that the application of Trichokompos doses had a significant effect on row length, cob diameter, and purple corn plant production. An application of 25 tons/ha of rich compost can be used as the most efficient recommended dose.
