Published: August 2023

Abstract
In the intricate tapestry of organizational dynamics, the pivotal process of decision-making emerges as a linchpin, wielding a substantial influence over companies' viability and enduring success. This study aims to explore the multifaceted factors that underscore sustainable organizational functioning, with a focus on the pivotal role of corporate governance. While the existing literature acknowledges the presence of corporate governance data, a notable gap exists in terms of investigating the nexus between corporate data governance, political affiliations, and their potential impact on financial reporting quality.This research seeks to bridge this gap by conducting a comprehensive inquiry into this complex interplay. Meticulous data collection from 48 carefully selected firms listed on the Palestine Exchange market forms the foundation of this study. Utilizing the analytical capabilities of SPSS, a robust statistical analysis is employed to elucidate the intricate relationship between two central variables: Financial Data Accuracy (FDA) and Political Connection Advantage (PCA).The results of this meticulous analysis illuminate the matter at hand. The intertwined variables exhibit a correlated relationship with financial reporting quality. This correlation not only underscores potential influences on various dimensions but also assumes a pivotal role in the sphere of decision-making within these scrutinized firms. Furthermore, this nexus holds the potential to exert a profound influence on the strategic considerations of these organizations.

Published: August 2023

Abstract
Background- Glutamine plays a vital role as an energy substrate the inflammatory response, prevention of organ injury and renal acid buffering. Parenteral glutamine supplementation could reduce in-hospital and ICU morbidity and mortality.
Objective- Aim of this systematic review and meta-analysis is to investigate the effects of parenteral administration of GLN in adult surgical critically ill ICU patients.
Study selection- Two-arm studies about adult surgical ICU patients undergoing postoperative glutamine-enriched parenteral nutrition (experimental cohorts) vs control ones.
Endpoints- Primary endpoint was in-hospital outcome (mortality, length of stay, length of mechanical ventilation). Secondary endpoint was the evaluation of nosocomial infections.
Results- According to PRISMA ® 2020 flow diagram, eight randomized controlled trials were included for a total of 603 patients. No significant differences about in-hospital and ICU mortality were found (p=0.16 and p=0.53, respectively). Parenteral glutamine-supplementation was associated with a reduction of hospitalization (p=0.02), without influencing nor ICU stay (p=0.35) neither postoperative mechanical ventilation (p=0.18). Finally, dipeptide administration did not reduce cumulative incidence of nosocomial infections (p=0.41); however, a protective role for postoperative pneumonia was reported (p=0.05).
Conclusions- Excepting for a reduction in hospital stay and incidence of nosocomial pneumonia, glutamine-dipeptide parenteral supplementation does not add any benefit in surgical ICU patients.
Machine Learning for Wireless Network Throughput Prediction
Authors: Fernandez Gustavo A 
Published: August 2023

Abstract
This paper analyzes a dataset containing radio frequency (RF) measurements and Key Performance Indicators (KPIs) captured at 1876.6MHz with a bandwidth of 10MHz from an operational 4G LTE network in Nigeria. The dataset includes metrics such as RSRP (Reference Signal Received Power), which measures the power level of reference signals; RSRQ (Reference Signal Received Quality), an indicator of signal quality that provides insight into the number of users sharing the same resources; RSSI (Received Signal Strength Indicator), which gauges the total received power in a bandwidth; SINR (Signal to Interference plus Noise Ratio), a measure of signal quality considering both interference and noise; and other KPIs, all derived from three evolved node base stations (eNodeBs). After meticulous data cleaning, a subset of measurements from one serving eNB, spanning a 20-minute duration, was selected for deeper analysis. The PDCP DL Throughput, as a vital KPI metric, plays a paramount role in evaluating network quality and resource allocation strategies. Leveraging the high granularity of the data, the primary aim was to predict throughput. For this purpose, I compared the predictive capabilities of two machine learning models: Linear Regression and Random Forest. Metrics such as Mean Absolute Error (MAE), Root Mean Squared Error (RMSE) were used to examine the models as they offer a comprehensive insight into the models accuracies. The comparative analysis highlighted the superior performance of the Random Forest model in predicting the PDCP DL Throughput. The insights derived from this research can potentially guide network engineers and data scientists in optimizing network performance, ensuring a seamless user experience. Furthermore, as the telecommunication industry advances towards the integration of 5G and beyond, the methodologies explored in this paper will be invaluable in addressing the increasingly complex challenges of future wireless networks.
New approaches regarding the electrochemical behaviour of the Ti-6Al-4V alloy functionalized with antimicrobial peptide JI-2 via plasma polymerization
Authors: Teixeira Gabriella Teresinha Lima , Gelamo Rogério Valentim , Leite Natália Bueno , Moreto Jeferson Aparecido 
Published: August 2023

Abstract
Ti-6Al-4V alloy is widely used in the biomedical sector due to its excellent biocompatibility, corrosion resistance, and mechanical properties. However, the use of this material as an implant is still susceptible to failure due to bacterial adhesion on the surface. Initial studies performed by this research group demonstrated and characterized the functionalization process of the Ti-6Al-4V alloy with antimicrobial JI-2 peptide via plasma polymerization method. However, the electrochemical properties of the functionalized system are still little explored. Here, we present new insights regarding the global electrochemical behaviour of the functionalized Ti-6Al-4V with PAA/JI-2 in 0.6 mol L-1 NaCl solution. Open circuit potential and electrochemical impedance spectroscopy techniques were used. The electrochemical tests were accompanied by a detailed microstructural analysis by SEM. The results demonstrated the PECVD technique was advantageous to produce thin films based on acrylic acid monomer on the Ti-6Al-4V surfaces. The PAA/JI-2 thin films shifted the corrosion potential (Ecorr) of the Ti-6Al-4V alloy to more positive values, indicating a better thermodynamic stability. The capacitance of the barrier layer decreases for the uncoated specimens with increasing immersion time, suggesting an increase in the thickness of the native oxide layer. In contrast, the opposite effect was verified for the Ti-6Al-4V/PAA/JI-2.

Published: August 2023

Abstract:
Cancer is becoming more common worldwide, impacting the vast majority of people.
As a result, new anticancer drugs are currently being created, and their safety is still being
assessed. Pyrazine-based medications are a substantial contribution, as they are one of the
most important pharmacophores found in heterocyclic compounds both synthetically and naturally.
It's a six-membered aromatic heterocycle with two nitrogen atoms with a wide range of
therapeutic applications in drug development and numerous prospects for future enhancement
in anticancer drugs by targeting several critical receptors. A number of pyrazine compounds
have been shown to inhibit enzymes, receptors, and a range of additional cancer-fighting targets.
Researchers are currently focused on the creation of pyrazine-based novel derivatives for
cancer treatment in combination with other moieties. As a result, this review illuminates the
recent therapeutic expansion of pyrazine-based drugs, as well as their synthetic schemes, tabulated detailed clinical
trial drugs, marketed drugs with their primary target, and a list of recently patented and published research papers,
all of which will help scientists build successful medications with the appropriate pharmacological activity.

Published: August 2023

Abstract:
Pulmonary aspergillosis is the most common mould infection of the lungs. Patients with chronic lung disease or mild immunodeficiency are at risk. Lung cancer represents an oncological challenge. Limited data are available about aspergillosis in newly diagnosed non-neutropenic lung cancer patients.

Objectives::
The aim of this work was to evaluate naïve lung cancer patients for the presence of as-pergillosis, identify fungal isolates, and determine antifungal susceptibility. The inhibitory effect of secondary metabolites of fungal isolates on the human fibroblast cell line was also assessed.

Results::
Aspergillus isolates were detected in 33 BAL samples out of the 69 patients (47.8%). The commonest isolate was A. niger. There was no significant correlation between total fungal count and age of patients. The antifungal Micafungin had a broad-spectrum and potent fungistatic activity against all fungal species, with A. niger being the most sensitive. MTT assay was performed to evaluate the cytotoxic effect of both A. niger and A. fumigatus on normal lung cells (WI-38) and re-vealed that toxicity was concentration-dependent and A. niger had significantly lower IC 50, indi-cating more toxicity.

Conclusion::
In the context of the diagnosis of lung cancer, maintaining vigilance is crucial to diag-nose fungal infection as aspergillosis. Initiation of proper management can help improve patient outcomes.

Published: August 2023

Background:
Hysterectomy is one of the factors that may affect women's body image and
self-esteem and lead to serious psychological complications.

Objective:
The study aimed to compare self-esteem, body image, and depression in hysterectomized
and non-hysterectomized Iranian women

Methods:
In this cross-sectional comparative study, 140 women of the reproductive age, who have
undergone hysterectomy with benign causes, were compared in terms of self-esteem, body image, and
depression with 140 women receiving medical treatment due to abnormal bleeding in educational and
medical centers in Tabriz, Iran. Sampling was conducted by convenience method. Self-esteem was
assessed with the Rosenberg self-esteem questionnaire, body image was assessed with the multidimensional body-self relations questionnaire, and depression was assessed with the Beck II
depression inventory. Data were analyzed by Pearson correlation test, independent t-test, chi-square
test, and general linear model.

(4.8) and it was 24.2 (3.4) in non-hysterectomized women (out of an achievable score of 0-30). The
mean (standard deviation) depression score was 18.1 (9.7) and 5.5 (4.6) out of 0-63 in hysterectomized and non-hysterectomized women, respectively. The differences in self-esteem, body image, and
depression variables were statistically significant in hysterectomized and non-hysterectomized women, respectively (P<0.001)

Conclusion:
According to the results of the present study, the body image and self-esteem in
hysterectomized women were low compared to non-hysterectomized women, while the level of
depression was high, and this difference was statistically significant.

Computational Quantum and Spectroscopic analysis of 4-Hydroxy-1-Naphthaldehyde

Background:
Known also as 4-Hydroxynaphthalene-1-carbaldehyde, 4-hydroxy-1-naphthaldehyde (4H1NA) is a crucial precursor of many coordinating agents. A commercial compound called 4-hydroxy-1-naphthaldehyde (4H1NA) can be used to make a number of different sensors. In the development of many chemosensors, they operate effectively as a functionalized fluorescent backbone.

Objectives:
Molecular Dynamic, Hirshfeld Surface, Computational Quantum analysis of Naphthalde-hyde.

Methods:
The methods employed in the analysis of the compound involve the DFT calculations, using the DFT method and B3LYP/6-311++G (d, p) basis set with respect to its FTIR, NMR, and UV-Visible spectrum. The NMR chemical shifts of carbon and protons in CDCl3 were determined by the GIAO method. For the molecule of reference, HOMO-LUMO and Donor-Acceptor interactions were also taken into consideration. Investigations also looked into E.L.F., Fukui activity, and non-linear optical properties.

Results:
The investigation of compounds at their atomic level was analyzed using computational methods so that chemical, medicinal, and environmental research make use of them to make the molecule more in an improved form with distinguished properties. Strong interaction has been produced as a result of electron transfer from the oxygen atoms lone pair LP (2) to the anti-bonding orbital *(C3-C5) with a significant stabilization energy of 42.61kcal/mol. The attributes of the NLO molecule were calculated and found to be superior to those of the urea molecule, with linear and first-order hyperpolarizability situations. Our findings imply that the reference molecule can be a heavier contender for NLO as a surface material and could be considered a vital substance for medical purposes in the drug industry due to its maximum electrophilicity index.

Conclusion:
A commercial compound called 4-hydroxy-1-naphthaldehyde (4H1NA) can be used to make several different sensors. The compound has good structural and optical properties. They can be employed for a variety of optical limiting applications because of their unusual optical characteristic, which exhibits third-order non-linear behavior.

Authors: Xie Guoshu , de Moura Ricketti Nicolas , Török Béla 
Published: August 2023

Introduction:
Sonication has been introduced as a green and effective activation method for
the selective monoamination of β-dicarbonyl compounds. The simple one-pot process resulted in different
substituted β-amino-ɑ,β-unsaturated esters and ketones at room temperature with quantitative yields.
Aqueous NH4OH was used as a safe and economical nitrogen source for pressurized NH3 gas. The process
is considered green, accounting for not using any solvents and catalysts, besides some aqueous
NH4OH-involved reactions using nontoxic water. A broad variety of useful synthetic intermediates, β-
amino-ɑ,β-unsaturated esters and ketones have been prepared in short reaction time.

Methods:
Using this developed protocol, we were able to synthesize a series of structurally diverse β-
amino-ɑ,β-unsaturated esters and unsaturated amino ketones.

Results:
The synthesis of target compounds was achieved in a truly green process with high atom economy
and excellent yields in a catalyst-free one-pot system in an aqueous medium using simple, commercially
available, inexpensive ammonium hydroxide as the source of the nitrogen. The high atom economy
has been accompanied by the formation of a small amount of nontoxic waste, water.

Conclusion:
In conclusion, a simple, convenient, and high-yielding catalyst-free environmentally benign
method was developed for the synthesis of unsaturated amino acid esters and unsaturated amino ketones.
Impregnation of Fe<sup>3+</sup> into MCM-41 Pores: Effect of Fe<sup>3+</sup> Concentration on the Weight Percent of Fe-Frameworks and Fe-Non-Frameworks
Authors: Suyanta Suyanta , Kuncaka Agus , Mudasir Mudasir 
Published: August 2023

Silica from rice husks (RH) has been used as a starting ingredient in the sonication synthesis of MCM-41 (RH-MCM-41). The impregnation of Fe3+ into RH-MCM-41 pores to produce RH-MCM-41 containing Fe2O3 and Fe (denoted as Fe2O3-Fe-RH-MCM-41) was carried out by examining the effect of various Fe3+ concentrations on the weight percent of Fe-frameworks (Fe3+ that replaces Si4+ in silicate frameworks) and Fe-non-frameworks, i.e., the iron oxide formed outside the silicate frameworks. Fe2O3-Fe-RH-MCM-41 was washed with a 0.01 M HCl solution to remove Fe-non-frameworks from the materials and give Fe-RH-MCM-41 containing Fe-frameworks. The Fe content in Fe2O3-Fe-RH-MCM-41 (Fe-total) and Fe-RH-MCM-41 (Fe-frameworks) for each sample was determined by an AAS (atomic absorption spectrometer), whereas the content of Fe-non-frameworks was calculated from the difference between Fe-total and Fe-frameworks. The XRD (X-ray diffraction) pattern, N2 adsorption-desorption isotherm profile, as well as the TEM (transmission electron microscope) image clearly demonstrate that the RH-MCM-41 exhibits an ordered p6mm hexagonal mesostructure with a large specific surface area and uniform pore size. Based on the weight percents of Fe-frameworks found in each sample, it is clear that the content of Fe-non-frameworks is significantly enhanced compared to that of Fe-frameworks when the more concentrated Fe3+ is used.

Published: August 2023

The complex containing iron(II), 2,6-bis(pyrazol-3-yl)pyridine (3-bpp) as ligand, and tetracyanonickelate as counter anion has been synthesized and characterized. The characterization data suggest the corresponding formula of [Fe(3-bpp)2][Ni(CN)4]·4H2O. Meanwhile, the SEM–EDX analysis image confirms the existence of all elements contained in the complex except the hydrogen atom. The infrared spectra exhibit vibration bands of the functional groups of 3-bpp ligand and [Ni(CN)4]−1 anion. From magnetic property measurement, the complex's molar magnetic susceptibility (XMT) value is 2.65 emu mol−1 K at 300 K, which contains about 75% high-spin state of the Fe(II) complex. Upon lowering the temperature, the XMT value gradually decreases around 1.37 emu mol−1 K at 13 K. It decreases sharply to about 0.73 emu mol−1 K at 2 K. These values reveal that Fe(II) complex is in the low-spin (LS) state. As a result, the complex exhibited spin-crossover characteristics of gradual transition without thermal hysteresis, and the transition temperature occurred below room temperature with a transition temperature (T1/2) close to 140 K. The spin crossover property of the complex is supported by a thermochromic reversible color change from red-brown at room temperature to dark brown on cooling in liquid nitrogen associated with the high-spin to low-spin transition.

Aim: to review the modern approaches to the diagnosis and treatment ofC. difficile-associated disease in adults and present the resolution of the Expert Council held on March 25, 2023 in Moscow.General provisions.C. difficileis the most important nosocomial pathogen which spores are also commonly found in the environment. Microbiota impairment, primarily due to the use of antibacterial drugs, is a key stage in the development ofC. difficile-associated disease. A search for an infection should be carried out only in patients with diarrhea, and it is advisable to use at least 2 laboratory methods. The drug of choice for first-line treatment is vancomycin. If drug treatment is ineffective or the patient has recurrent clostridial infection, fecal microbiota transplantation should be considered. The probiotic strainSaccharomyces boulardii CNCM I-745has a direct inhibitory effect onC. difficiletoxin A, promotes normalization of the intestinal microbiota composition, and decreases the inflammatory reaction in colonic mucosa colonized with a toxigenic strain ofC. difficile.Conclusions. Addition of the probiotic strainSaccharomyces boulardii CNCM I-745to antibacterial therapy promotes both primary and secondary prevention ofC. difficile-associated disease.

Published: August 2023

Aim: the reason for the publication was the rare occurrence, as well as the non-specificity of symptoms of the cystic form of duodenal dystrophy. The listed features of this disease lead to difficulties in its differential diagnosis and the choice of the optimal method of treatment.General statements. The report is devoted to the description of a case of successful treatment of a cystic form of duodenal dystrophy — a chronic inflammation of the pancreatic tissue, ectopic in the wall of the duodenum. A 47-year-old patient was admitted to the clinic with complaints of persistent abdominal pain, periodic vomiting, general weakness, weight loss of 20 kg in three months. With the help of computed tomography, the diagnosis was established, the tumor process was rejected, and chronic pancreatitis was detected in the orthotopic pancreas. Due to the presence of changes in the main pancreas, the patient underwent pancreatoduodenal resection. The features of the operation were pronounced infiltrative changes and pronounced vitreous tissue edema, which made it difficult to mobilize the hepatic flexure of the colon and duodenum.Conclusion. Pancreatoduodenal resection is the optimal surgical intervention for the combination of cystic form of duodenal dystrophy with sub-/decompensated duodenal stenosis.
