Published: February 2024

Abstract
Physical and chemical water quality characteristics were studied in six of Lake Tana. The purpose of the study was to explore how different methods describe the “health” of the wetlands and how different approaches relate to each other. The physicochemical parameters were measured in-situ with portable multimeter and nutrients and chlorophyll a were determined by following the standard procedures outlined in the United States Environmental Protection Agency using UV/Visible photometer (Spectrophotometer). The trophic state index (TSI) of wetlands was determined using trophic state variable and Carlson model. The lake water quality index (WQI) was also evaluated using data from multiple water quality parameters into a mathematical equation to express the overall water quality at each study wetland and season. The water quality datasets were subjected to four multivariate statistical techniques, namely, univariate analysis of variance (univariate ANOVA), cluster analysis (CA), principal component analysis (PCA) and factor analysis (FA). Analysis of the physicochemical dataset using univariate analysis indicated a significant interaction between wetland and season (ANOVA, p < 0.05) for the mean value of dissolved oxygen, electrical conductivity, Secchi depth a.m., and p.m., salinity, nitrate, total ammonia, total nitrogen, total phosphorous, and Chlorophyll-a while water temperature, water depth, soluble reactive phosphorous were not affected (ANOVA, p > 0.05) by the interaction between wetland by season. Spatial diversity and site grouping based on water quality characteristics using CA, PCA and FA analysis grouped the 6-wetlands into four clusters based on the similarity of water quality characteristics. The four clusters displayed in the dendrogram were grouped into least polluted cluster 1 (WO and RA), slightly polluted cluster 2 (MRM). moderately polluted cluster 3 ( GRM and ZG ) and highly polluted cluster 1 (AV). There was a significant interaction between wetland and season (ANOVA, p < 0.05) for the mean value of total trophic state index (TOTTSI), total nitrogen trophic state index (TSITN), total phosphorous trophic state index (TSITP,), total chlorophyll-a trophic state index (TSIChla) ,and total Secchi depth trophic state index (TSISTD). However, there was no a significant interaction between wetland and season (ANOVA, p > 0.05) for the mean value of WQI. In conclusion, ranking of the pollution status of wetlands of Lake Tana using different approaches in this study using multivariate statistics, Carlson TSI, and WQI model suggest that some wetlands did not fit completely in the same category The current study on water quality variables of Lake Tana recommends that top priority should be given to regular water quality monitoring, in conjunction with biodiversity and fish health assessment.

Authors: Faisal Anwer Jaber , Al-Imam Mokhtar Jawad , Abbood Alaa Saadi 
Published: February 2024

Abstract
Introduction: Sexually transmitted diseases (STDs) are a severe problem because many infections are asymptomatic or have fewer symptoms and account for about 20% of male infertility.
Objective: This study developed Real-time PCR kits to detect Treponema pallidum, Neisseria gonorrhoeae, Mycoplasma species, and Trichomonas vaginalis in infertile and fertile men's semen.
Methods: Men aged 24–55 with no children and a conceiving issue were the patient group, while men aged 18–49 with at least one child and a standard seminal fluid check were the control group. The Amplisens® MULTIPRIME-FRT PCR kit was used to analyze the DNA for the human beta-globin HBB gene to determine if it came from the isolated pathogen.
Results: The study revealed that out of the patient group, 22 out of 54 individuals tested positive (40.9%) for N. gonorrhoeae, 7 out of 54 (31.8%) for T. pallidum, 4 out of 54 (18.18%) for M. genitalium, and 2 out of 54 (9.09%) for T. vaginalis. In the control group, which consisted of 13 males, only one infection with N. gonorrhoeae was detected.
Conclusion: The four urogenital infections evaluated were common in infertile people. However, they may not be the only cause of male infertility in this region.

Published: February 2024

Abstract
In the present research work, the Ag NPs were synthesized by chemical reduction method using AgNO3 as a reducing agent and NaBH4 as stabilizing agent and reducing agent as well. The structural properties and crystallite size of the prepared sample were investigated via X-ray diffraction (XRD) spectroscopy. XRD revealed the cubic structure. Fourier transform infrared spectroscopy (FTIR) was used to investigate the chemical bond vibrations of the different groups present in Ag NPs. UV-Vis spectroscopy was done to observe the abortion spectrum of Ag NPs. The surface morphology was examined via scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Afterwards, synthesized AgNPs have been used for the fabrication of cholesterol biosensor using three electrode system. The glassy carbon electrode (GCE) was used as working electrode. Finally the electrochemical measurements have been performed for the different concentration of cholesterol. The linearity response was observed between the potential difference and concentration of cholesterol, which shows that our material is effective for the fabrication of cholesterol biosensor.

Abstract

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest and most metastatic cancers in human. PDACs respond poorly to therapies, partly due to cancer stem cells (CSCs) that self-renew, survive chemotherapies, metastasise and replenish the tumour. Factors secreted by tumour cells mediate autocrine/paracrine crosstalk with surroundingcells contributing to the stem cell niche but are still insufficiently characterised. Here we used quantitative SILAC proteomics to identify secreted factors enriched in CSC secretome compared to non-CSCs. Among them were GDF15 and VGF, factors involved in cachexia and pain stimuli. GDF15 and VGF promoted CSC self-renewal and growth through autocrine effects. TGFβ/Activin signalling lowered GDF15 and VGF expression via SMAD2/3-SMAD4-SNON, switching to ATF4-CREB-mediated induction upon cell stress. Co-culture of PDAC-CSCs and hESC-derived neural cells for mimicking cellular crosstalk in PDAC revealed that paracrine signalling via GDF15/VGF promoted nociceptor formation and neurite outgrowth. In turn, Substance P from neurons supported CSC self-renewal, EMT/migration and clonal evolution that was also impacted by SMAD4 genetic status. Lastly, the serum levels of GDF15 and VGF were elevated in PDAC patients suggesting their utility as biomarkers for PDAC detection. Collectively, our data uncovered that cachexia and pain signalling factors mediate the crosstalk between CSCs and nociceptors.
Concave Surface-Enriched Reactant Boosts Electrocatalytic C2H4 Production from Coal-Derived C2H2 via π-Electron Delocalization Effect

Published: February 2024

Abstract
Electrocatalytic semihydrogenation of acetylene (C2H2) provides a facile and petroleum-independent pathway for ethylene (C2H4) production. However, the reliance on the preseparation and concentration of raw coal-derived C2H­2 hinders its economic potential. Here, density functional theory calculations demonstrate that a concave surface leads to a polarization electric field, which is beneficial for enriching the electrophilicity C2H­2 and is suitable for direct conversion of raw coal-derived C2H2. Then, a porous concave carbon-supported Cu nanoparticles (Cu-PCC) electrode is designed to enrich the feeding C2H2 gas. As a result, the as-prepared electrode enables a 91.7% C2H4 Faradaic efficiency and 81.26% C2H2 conversion under a simulated raw coal-derived C2H2 atmosphere (~15%) at a current density of 420 mA cm−2, greatly outperforming its counterpart without concave surface supports. Moreover, a series of characterizations reveal that the strengthened intermolecular π conjugation caused by the increased C2H2 coverage leads to the delocalization of π electrons in C2H2, consequently promoting C2H2 activation, suppressing HER competition and enhancing C2H4 selectivity.
Development of an artificial neural network to maximize the reproducibility of dyeing polyamide fabrics

Published: February 2024

Abstract

The Brazilian textile industry is an essential pillar of the country's economy, standing out globally as the fifth-largest textile hub and the fourth-largest in the clothing segment. However, one of the critical challenges faced by this sector is the reprocessing of fabrics, which leads to delivery delays, quality impacts, increased costs, and environmental impacts. Therefore, the aim of this study is to identify reprocessing in the dyeing process of a textile industry through preestablished patterns using a neural network. To achieve this goal, this research is being conducted in partnership with a company in the sector, focusing on data collection, preparation, processing, training and validating the neural network. Specifically, the focus is on the data collected from the production of polyamide, where approximately 95% of the reprocessing is classified as undefined, making the identification and precise resolution of these issues challenging. Thus, this research aims not only to enhance the efficiency of polyamide production but also to contribute to resource savings and compliance with environmental commitments, consolidating the concept of sustainability in the textile industry. The incorporation of artificial intelligence, such as neural networks, has emerged as an essential strategy to drive the textile industry toward more efficient and less impactful practices.

Abstract

Objectives. To evaluate both the short-term and long-term outcomes of odontoid screw fixation (OSF), identifying potential risk factors for implant-related complications in patients with odontoid fractures.
Methods. This is a retrospective observational cohort study. Inclusion criteria were as follows: 1) Type II fractures and rostral Type III fractures, according to the Anderson and D’Alonzo classification; 2) patients older than 15 years. Exclusion criteria were: 1) other Type III injuries; 2) osteoporosis confirmed by densitometry or a CT bone density score below 100 Hounsfield units; 3) odontoid fractures related to tumors or aneurysmal bone cysts.
Results. In total, 56 patients were considered for the analysis of short-term results, and 23 patients were evaluated for long-term outcomes. No significant differences were observed in the preoperative imaging data and intraoperative features of OSF between patients with Type II and rostral Type III fractures. The mean operative duration was 63.9 ± 20.9 minutes, and the mean intraoperative blood loss was 22.1 ± 22.9 ml.
Screw cut-out was identified in four patients with rostral Type III fractures (p = 0.04). The rate of screw cut-out was found to correlate with the degree of dens fragment displacement. The bone fusion rate was 91.3%. CT scans identified stable pseudarthrosis in two cases. We observed C2-C3 ankylosis in all cases following partial disc resection. One third of patients with screws placed through the anterior lip of C2 showed no C2-C3 ankylosis. A strong trend towards lateral joint ankylosis formation in patients with a median lateral mass dislocation of 11.9 mm was observed. Most SF-36 scores either matched or exceeded the corresponding normal median values in the published reference database.
Conclusions. OSF is a reliable treatment method of type II and rostral type III odontoid fractures with fragment displacement of 4 mm or less. The minimally invasive OSF through the anterior-inferior lip of C2, using monocortical screw placement and cannulated instruments, without rigid intraoperative head immobilization, is sufficient to achieve favorable clinical and fusion results. This technique reduces the risk of ankylosis in the C2-C3 segment. OSF restore the quality of life for patients with odontoid fractures to levels comparable to those of the general population norm.

Abstract

Background
Anesthesiologists are involved in most blood transfusions during the perioperative period, trauma resuscitation, critical care, and obstetric hemorrhage. Transfusion refers to the administration of blood and blood products, such as whole blood, packed red blood cells, fresh frozen plasma, platelets, and concentrated fibrinogen etc. These products aim to maintain the ability to carry oxygen and restore the blood clotting property. This study aims to know the awareness of Syrian Private University students about modern strategies for blood transfusion in the perioperative period.
Methods
This is a cross-sectional study that used a questionnaire in the form of an electronic survey that was administered among medical college students at the Syrian Private University. 277 students answered the questionnaire. The electronic questionnaire included a set of variables, including demographic and personal information for students, variables about indications for blood transfusion during surgery, rules for preserving blood, and a study of knowledge about how to transfer, use, and methods of preserving blood products and their benefits.
Results
The average of the students’ answers about the indications for blood transfusion during surgery was 1.81 ± 1.5, and the average of the students’ answers about the issues that they should take into consideration when transfusing blood was 2.93 ± 2.203. The majority of the students answered correctly when asked about the rules for blood preservation, and the average of the students’ answers about knowledge with the rules for dealing with a blood sample of 1.92 ± 0.96, the majority of students answered correctly when asked about concentrated red blood cells, and the average answers when asked about platelets and plasma was 4.31 ± 2.36, and the average answers of students when asked about complications was 4.31 ± 232. In our study, the percentage of female knowledge was higher Among males (statistical significance = less than 0.05), except for the rules of blood conservation and knowledge of red blood cells, knowledge was greater among males (statistical significance = less than 0.05).
Conclusion
The degree of students’ knowledge about the indications for blood transfusion, the matters that must be taken into consideration during blood transfusion during surgery, the rules of blood preservation, and knowledge about platelets and plasma, was weak and below the expected level, while their degree of knowledge about the complications of blood transfusion was good.

Salah satu tipe rumah tradisional di Sumatera Selatan adalah Rumah Ulu banyak ditemui di dataran tinggi dan pegunungan di Kab. Muara Enim khususnya Desa Pulau Panggung, Kec. Semende Darat Laut,. Rumah ini memiliki karakter rumah tradisional berupa rumah panggung (bangunan rumah kayu yang ditopang oleh beberapa tiang kayu atau batang pohon secara utuh). Saat ini, Rumah Ulu/Semendo telah mengalami banyak perubahan dari sisi arsitektur, yakni perubahan material dan perubahan fungsi ruangan. Hal yang paling mencolok adalah banyaknya kolong rumah Ulu/Semendo telah berubah fungsi menjadi ruang tamu, garasi ataupun sebagai tempat berjualan. Perubahan-perubahan ini terjadi dengan sangat signifikan sehingga pada masa sekarang, Rumah Ulu asli sudah sangat sulit untuk ditemukan utuh. Tujuan dari penelitian ini adalah mengetahui perubahan material dan fungsi ruang pada rumah Ulu/Semendo di Kecamatan Semende Darat Laut. Metode yang digunakan adalah metode kualitatif. Metode pengambilan data dilakukan dengan cara in-depth interview, dokumentasi, dan observasi lapangan. Hasil penelitian yang ditemukan adalah Rumah Ulu/Semendo berangsur-angsur mengalami perubahan dari segi material dan fungsi ruang. Saat ini sangat sulit untuk menemukan Rumah Ulu/Semendo yang masih asli. Perubahan-perubahan ini sangat dipengaruhi sulitnya menemukan bahan material asli sehingga masyarakat harus mensubsitusi dengan bahan material lain. Selain itu, perubahan ini juga terjadi dikarenakan, masyarakat di daerah Semendo memiliki kebutuhan-kebutuhan tambahan akan sarana dan prasarana seperti dapur, toilet, dan sebagainya. Pada akhirnya, lambat laun, Rumah Ulu/Semendo akan mulai hilang dan tidak dapat ditemukan lagi.
