VALIDATION OF ANALYTICAL METHOD FOR QUANTIFICATION OF NATURAL ESTROGENS (E1, E2, AND E3) AND SYNTHETIC (EE2) IN SURFACE WATERS AND SUSPENDED PARTICULATE MATERIAL OF A SOUTH ATLANTIC SUBTROPICAL ESTUARY, BRAZIL. Marine pollution has become relevant for coastal conservation units and ecosystems of great ecological importance. This study validated analytical methods to investigate the occurrence of the emerging contaminants 17β-estradiol (E2), estrone (E1), estriol (E3), and 17α-ethinylestradiol (EE2) in surface waters and suspended particulate matter (SPM) from Guaratuba Bay, South Atlantic, Brazil. The analysis was performed by liquid chromatography coupled to a fluorescence detector (LC-FLD) after pre-concentration of surface water samples by solid phase extraction (SPE) or solid-liquid extraction for SPM samples. The recovery percentages were between 48 and 87%, and the coefficient of variation (CV) between 3 and 24% for SPM and from 64 to 107% (CV of 4 to 42%) for surface water. The method thus proved to be accurate and precise at the concentrations studied (ng g-1 and µg L-1). The concentration ranged from 10 to 177 ng L-1 in surface waters and from 392 to 4108 ng g-1 in SPM. E2, EE2, and E3 were found in SPM under different climatic conditions and population occupation. EE2 was determined in all sampling campaigns, especially in summer, when the number of tourists increases considerably. The presence of EE2 in the SPM of Guaratuba Bay warns for possible implications for the health of coastal environments.

Even though pollination is an ecosystem service of great importance for humanity, in many megadiverse countries such as Peru, little is known about the diversity of pollinators and floral visitors, their interactions, their dynamics and biogeographic distribution. Thus, we highlight the need of information on the diversity of pollinators and their interactions with plants in the Peruvian territory, and to identify information gaps. We compiled and identified 162 bibliographic sources on pollination interactions in Peru published from 1965 to 2023. We noted 2,537 interactions, corresponding to 970 species and morphospecies of plants distributed mainly of the orders Asterales, Lamiales and Fabales; and 671 species and morphospecies of animals of the classes Arachnida, Insecta, Mammalia and Aves. Finally, we identified 207 sampling locations for pollination interactions at the national level. Among which the departments with the greatest number of records were Lambayeque, Cusco, Huánuco, Lima, Madre de Dios and Cajamarca; in contrast, we did not find records for Ayacucho, Moquegua and Tacna. With this information, we corrected some information gaps regarding the knowledge of the diversity of the pollination interactions and floral visits in Peru..

Authors: Yao Ji , Zhang Li , Zhou Zezhi , Liu Jiqiang , Cheng Jie , Long Fan , Yuan Ting
Published: August 2024

Introduction:

In this study, the molecular mechanisms through which Lascorbate
(Vitamin C) potentially treats Chronic Obstructive Pulmonary Disease
(COPD) were identified. A non-targeted metabolomics analysis revealed metabolic disorders
and significantly reduced levels of L-ascorbate in COPD patients compared to
healthy subjects.

Method:

The COPD rat model was established by exposing them to Cigarette Smoke (CS).
The L-ascorbate intervention reduced lung inflammation and histological damage in
COPD rat models. Network pharmacology analysis revealed 280 common targets between
L-ascorbic acid (drug) and COPD (disease), of which seven core targets were
MMP3, MME, PCNA, GCLC, SOD2, EDN1, and EGF. According to molecular docking
prediction, L-ascorbate had the highest affinity with EGF. Molecular dynamics simulation
indicated relatively stable EGF and L-ascorbate complexes.

Results:

The PI3K/AKT signaling pathway was significantly enriched in the Kyoto Encyclopedia
of Genes and Genomes (KEGG) functional analysis.

Conclusion:

Finally, the in vivo and in vitro experiments confirmed that L-ascorbate affected
COPD by regulating the EGF/PI3K/AKT pathway. In summary, based on network
pharmacology and molecular docking analyses, this study revealed that L-ascorbate
affects COPD development by regulating the PI3K/AKT signaling pathway
through EGF, and thus contributes to the understanding and clinical application of Lascorbate
in the treatment of COPD.

Comprehensive Analysis and Experimental Validation of TLL2 as a Potential New Prognostic Biomarker Associated with Immune Infiltration in
Lung Adenocarcinoma
Authors: Jiang Jing , Du Zhongye , Tang Haijuan , Huang Yingying , Li Dongbing , Liang Qiuli
Published: August 2024

Background:

The precise function of Tolloid Like 2 (TLL2) remains uncertain within
the context of Lung Adenocarcinoma (LUAD).

Objective:

The primary objective of this investigation was to conduct a thorough analysis.

Methods:

To assess its diagnostic utility, data from The Cancer Genome Atlas (TCGA) database
were used to assess TLL2 expression in pan-cancer and LUAD. The study has also investigated
the correlation between TLL2 expression levels and LUAD symptoms and prognosis. Furthermore,
the study has explored possible regulatory networks involving TLL2, including its association
with immune infiltration, tumor stemness index (mRNAsi), and drug sensitivity in LUAD.
We have explored TLL2 expression in single-cell sequencing of LUAD and the genomic variation
and clinical significance of TLL2 in LUAD. The expression of TLL2 has been validated in
GSE87340 and cell lines by quantitative Real-time PCR (qRT-PCR).

Results:

An abnormal expression of TLL2 has been found in pan-cancer and LUAD. In LUAD patients,
elevated levels of TLL2 were significantly related to the T stage (p = 0.046) and the pathological
stage (p = 0.016). The expression of TLL2 in patients with LUAD was significantly associated
with poorer Overall Survival (OS) (p < 0.001). The expression of TLL2 was determined to be
an independent predictor of poorer OS (p = 0.042). TLL2 was associated with ribosome, neuroactive
ligand-receptor interaction, allograft rejection, ECM receptor interaction, asthma, porphyrin
and chlorophyll metabolism, focal adhesion, pentose and glucuronate inter-conversions, and ascorbate
and aldarate metabolism. The expression of TLL2 in LUAD was correlated with immune infiltration
and mRNAsi. The expression of TLL2 was significantly and negatively correlated with
TAK-715, XMD13-2, STF-62247, OSI-930, and EHT-1864 in LUAD. The TLL2 gene was up-
-regulated in multiple individual LUAD cells. LUAD patients with altered TLL2 had a shorter
PFS as opposed to those with unaltered TLL2. The expression of TLL2 was significantly increased
in LUAD cells.

Conclusion:

For patients with LUAD, TLL2 may serve as an immunotherapeutic target and a useful
prognosis biomarker.

Authors: Abdallat Mahmoud , Al-Sanouri Mohammad , Al-Salaymeh Suhayb , Zoubi Mohammad , Barakat Tamer , Badwan Ahmad , Alzubi Abdallah , Murshidi Rand
Published: August 2024

Background

Internet gaming disorder is defined as “Persistent and recurrent use of the internet to engage in games, often with other players, leading to clinically significant impairment or distress.” It is a new evolving disorder that affects many life aspects; therefore, it needs further investigation among different population groups. IGD was introduced for the first time in 2013 in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders, and it suggested carrying out further research among different populations. In 2018, Gaming Disorder (GD) has officially become a type of addiction as the World Health Organization released the 11th revision of the International Classification of Diseases (ICD-11)

Aims

The objective of this study is to investigate the prevalence of internet gaming disorder (IGD) and its association with sleep quality and academic performance among Jordanian university students aged 18-26. Our literature review revealed a lack of research on this topic concerning this specific population and culture. Therefore, our study aims to contribute to the existing literature and to provide insights that can inform prevention, assessment, and treatment strategies for those affected.

Methods

A cross-sectional study design was used by employing convenience and snowball sampling; a total of 2473 participants completed an electronic self-administered questionnaire that included the Internet Gaming Disorder Scale-SF (IGDS9-SF) and Pittsburgh Sleep Quality Index (PSQI). Of these, 432 were excluded based on our criteria. Our inclusion criteria required participants to be Jordanian university students between the ages of 18 and 26, enrolled as undergraduates at Jordanian universities, and free of neurological or psychiatric conditions.

Results

The prevalence of IGD in this study was 15.2% and was more prevalent among males compared to females (p= <0.001). Poor sleep quality was reported by 64.6% of the study population and was more frequently observed in females. Age and academic achievements (GPA) were not associated with having IGD. When binary logistic regression was used, IGD (OR=1.882) positively predicted poor sleep quality.

Conclusion

Internet gaming disorder is common among Jordanian university students and is associated with poor sleep quality, and our findings have significant implications for policymakers, educators, and healthcare providers in raising awareness about the IGD and its impact on sleep quality.
Stereochemistry of Organic Compounds-I
Authors: Bansal Anshul
Published: August 2024

This chapter provides a thorough exploration of the stereochemistry of organic
compounds, a fundamental aspect of organic chemistry that influences the physical and chemical
properties of molecules. The chapter begins with isomerism, distinguishing between the different
types of isomers and setting the stage for a deeper investigation into structural isomerism and
stereoisomerism.Structural isomerism is examined, focusing on isomers that differ in the connectivity of their atoms,
affecting their chemical behavior and properties. Stereoisomerism, which includes isomers with the
same connectivity but different spatial arrangements, is introduced as a key concept in understanding
molecular diversity.
Optical isomerism is detailed, highlighting the role of chirality and the ability of certain molecules
to rotate plane-polarized light. The concept of chirality is expanded upon, discussing chiral centers
and the absence of elements of symmetry, which leads to the existence of non-superimposable mirror
images.
Enantiomerism, the relationship between pairs of chiral molecules that are mirror images of each
other, is explored, emphasizing its significance in biological systems and pharmaceuticals.
Projection formulas, including Fischer and Newman projections, are introduced as tools to represent
three-dimensional structures in two dimensions, aiding in the visualization and differentiation of
isomers. Diastereomers, stereoisomers that are not mirror images, are discussed with a focus on their
different physical and chemical properties compared to enantiomers. The concept of prochirality is
introduced, explaining how certain molecules can become chiral through specific chemical
modifications.Resolution techniques for separating racemic mixtures into individual enantiomers are covered,
highlighting methods such as chiral chromatography and enzymatic resolution. Racemic mixtures,
equimolar mixtures of enantiomers, are examined in terms of their formation and the challenges
they present in synthesis and analysis.
This chapter equips readers with a comprehensive understanding of stereochemistry, providing the
knowledge necessary to predict and explain the behavior of organic compounds based on their threedimensional structures, essential for advanced studies and practical applications in organic
chemistry.

A stock split is an activity of splitting a number of outstanding shares of a company to make stocks more liquid so that they can increase transactions from market. The purpose of this study to determine that is any differences between return and trading volume before and after stock splitting. This study uses secondary data that accorded by Investing.com with a research period of 2017 – 2021. The population in this study are companies that performs stock split in the research year determined, that is 64 companies. The sample selection uses a purposive sampling method, so the sample from this research is 61 companies. The result of this study using the Wilcoxon signed rank test, the results is all sectors did not have an increase in stock returns and trading volume after stock splits because investors prioritized company fundamentals rather than stock split announcements. So for companies that want to do a stock split, should improve the company's fundamentals and pay attention to the economic conditions at that time first. This is because investors have other factors to consider in making transactions, one of which is fundamental factors and economic conditions.

Authors: Pasaribu Dedy Than
Published: August 2024

Stock split is a corporate action intended to raise stock liquidity. When stock prices are high, the shares become inaccessible to all capital market investors. The impact of stock splits on abnormal returns and stock liquidity should be re-evaluated due to the discrepancies in prior studies. This research evaluates the influence of stock splits on liquidity and abnormal stock returns. This research utilized a sample of 27 blue-chip companies listed on the IDX that underwent stock splits from 2010 to 2022. Blue chip stocks are often the market leaders for each sector and subsector of stocks in the capital market. Variations in blue chip stocks can certainly have an impact on other common stocks in each sector and subsector. The Wilcoxon signed-rank test was used to assess differences. The study period spanned ten days, with five days before and five days after the stock split. This research discovered disparities in the abnormal returns and liquidity of the company shares that were part of blue-chip stocks before and after the stock split.

Published: August 2024

LPS has liquidated a total of 117 banks by 2021 due to financial distress and the inability to maintain their health. This study aims to analyze the health level of banks through RGEC concerning banks that do not experience, are at risk of, and experience financial distress. Using a descriptive analysis method, banks are categorized based on three levels of potential financial distress according to Grover or G-Score, then evaluated through RGEC assessments in each bank category. The results indicate that, along with the decrease in G-Score, high NPL and low LDR reflect a greater potential for financial distress. Assessment of GCG through managerial ownership, profitability through ROA is not the sole factor indicating potential financial distress. However, low NIM may reflect a high potential for financial distress. Meanwhile, CAR shows high and very healthy values for all bank categories. This suggests that banks need to improve their health through risk management and increase Grover’s value by enhancing working capital, profits, and assets returns, so that banks can not only increase Grover’s value but also strengthen their position as financial institutions.
