Published: December 2023

The bacterial ability to form biofilm had been complicated the infection healing process, due to antibiotic resistance. Urinary tract infection is an optimal example of such infections that caused by bacterial biofilms. So the current study aimed to find an alternative method to inhibit the uropathogenic bacteria using nanotechnology. Uropathogenic Escherichia coli (UPEC) was isolated from 110 clinical samples. These bacterial isolated were tested for their ability to form biofilm by two methods: Microtiter plate and congo red agar. Antibiotic susceptibility was detected to determine the multidrug-resistant isolates. An ecofriendly green method was depended for the synthesis of silver nanoparticles (AgNPs) using alcoholic extract of Lepidium meyenii yellow root.  Silver nanoparticles were characterized by several techniques, and it was detected with a diameter of 44.89 nm. Anti-biofilm activity of AgNPs alone and with antibiotic was detected and the Scanning electron microscopy observations clearly indicated that 7.1825 mg/ml AgNPs prevented the biofilm formation. This is the first worldwide evidence-based research study about the  biosynthesis of silver nanoparticles from alcoholic yellow root extract of plant Lepidium meyenii and use it against UPEC biofilm.

Published: December 2023

The better approach to control the contamination of food by aflatoxin (AF), is identifying the fungal strains responsible for producing that toxin. To estimate the presence of aflatoxigenic fungi growth and AFs in pistachios, thirty two pistachios samples (8 fresh and 24 salt roasted) were collected from Sulaimani markets (Iraq).Rapid screening method for AFs production were utilized initially based on culture methods, the positive samples confirmed by polymerase chain reaction (PCR) that were applied using DNA extracted from the isolates of A. flavus targeting the genes (afR, aflP, aflD, and aflQ). For determination of AF production of those isolates, ELISA technique was applied. The results show, contamination of 20 (62.5%) samples of pistachios with fungi, among them A. flavus was the predominant. Ten (71.4% (of the A. flavus isolates were amplified the target genes by applying PCR, indicating their ability to produce AFs. Application of ELISA technique revealed AFs detection in 21(65.6%) samples of pistachios. The mean levels of AFs determined   were 6.06 and 12.08 μg/kg in fresh and salt roasted samples respectively. 19 (59.4%) of pistachio samples were exceed the maximum allowable limit set by the European union of total AFs concentration .Strong correlation obtained between AFs gene expression with AFs production. However, to avoid false negative and false positive results, applying more than one diagnostic molecular technique were suggested.
Leakage-free Wood-Derived Activated Carbon/Methyl Palmitate composite phase change material for thermal management applications
Authors: HEKİMOĞLU Gökhan
Published: December 2023

This study aimed to create a leakage-free composite phase change material (PCM) that has high potential for various thermal management applications. Activated carbon derived from wood (ACW) with a porous structure was used to address the leakage issue and improve the thermal conductivity of Methyl palmitate (MPt) used as the PCM. The optimum MPt impregnation ratio was found to be 53 wt% in the leakage-free ACW/MPt composite. The results of FTIR analysis showed that the integration of MPt and ACW was achieved through physical interaction. Scanning electron microscopy (SEM) analysis indicated that MPt was uniformly distributed within pores of the ACW scaffold. DSC analyses demonstrated that the fusion enthalpy and temperature of the ACW/MPt (53 wt%) were 129 J/g and 27.59 °C, respectively. Thermal gravimetric analysis (TGA) measurements confirmed that the ACW/MPt was thermally stable. By incorporating MPt with ACW, thermal conductivity of MPt was increased by 2.16 times. The fusion enthalpy of ACW/MPt did not change, and the melting temperature remained constant after 750 thermal cycles. The results of this study indicate that the fabricated leak-free ACW/MPt is cost-effective and environmentally friendly and has the potential to be utilized as a thermal energy storage (TES) material for temperature regulation in various applications.

Authors: DALĞIÇ Berat Fırat , AYDIN Selman
Published: December 2023

In the realm of energy sources, non-renewable fossil fuels, such as petroleum derivatives, continue to pose a significant threat to our planet. Currently, hydrogen energy, derived from renewable sources, is under extensive research, primarily due to its high efficiency, versatile applications, and zero carbon emissions. Hydrogen gas has become an indispensable alternative energy source owing to its numerous advantages. The technology that enables efficient utilization of hydrogen gas as an energy source is fuel cells, with Polymer Electrolyte Membrane Fuel Cells (PEM Fuel Cells) being the most significant advancement in this field. In this study, anode and cathode moisture levels were investigated by experimental study on the obtained efficiency of PEM fuel cell performance. Pure hydrogen and oxygen gases were used in the anode and cathode sections of the experiment, respectively. The test stand and a 6 cell 35 watt fuel cell with 9 cm2 active area were used for the test. Temperature and water accumulation, especially humidification in PEM fuel cells, can be achieved by keeping the hydrogen flow, oxygen flow and battery temperature under control. In the experimental study, the fuel cell humidification rate is gradually increased by keeping the flow and line temperature constant. 30% - 35% - 40% - 45% - 50% - 55% - 60% - 65% - 70% of the results obtained in the voltage, amperage and their effects on watts. As a result of the experimental study, humidification rate has a significant effect on the performance of PEM fuel cell. With the increased humidification temperature, the performance of the installed system increased significantly and nominal values were found. However, it is observed that the performance decreases after a certain period of time in the values higher than 60%.
L’Armenia in epoca di Putin: tra “trappole territoriali”, rischio di isolamento e tensioni post sovietiche
Authors: Jelen Igor , Džajić Uršič Erika
Published: December 2023

La consapevolezza di rappresentare un’antica cultura, nonché una tradizione di resistenza alle varie potenze che di volta in volta si sono affermate in quello spazio, costituiscono oggi probabilmente la principale risorsa della comunità statuale armena. Un elemento di identità che significa per il paese la consapevolezza di rischiare continuamente per la propria sopravvivenza in un contesto come quello del Caucaso esposto a tensioni che si ripercuotono a scala molto vasta. In queste circostanze il territorio armeno appare come un “buffer” tra grandi potenze, ex superpotenze in fasi di declino e potenze regionali in ascesa, che fanno spesso ricorso a espedienti geopolitici – tra i quali il cosiddetto “corridor approach” – per riaffermare posizioni di potere. Una situazione in cui la sopravvivenza millenaria del paese, e della sua straordinaria cultura, appaiono qualche cosa di eroico, che merita l’attenzione di tutta l’umanità. Un fatto ancor più importante considerando che il paese riesce a mantenere un ordinamento democratico, seppure tra varie contraddizioni, e una politica di collaborazione internazionale

Cauliflower is a vegetable that has commercial value and good prospects, especially for public consumption. According to the Central Bureau of Statistics of the Republic of Indonesia cauliflower production has decreased from 2019 to 2021, it is necessary to improve maintenance, one of which is by pruning lateral branches to increase productivity, thereby increasing the rate of photosynthesis to produce high productivity and the right dose of NPK fertilizer to maximize growth in the vegetative and generative phases thereby increasing the yield of cauliflower plants. This study aims to determine the effect of pruning lateral branches and doses of NPK fertilizer on the growth and yield of cauliflower.

The research was conducted in the hamlet of Jinarum, Girilayu, Matesih, Karanganyar from July to September 2022. The research method used a Completely Randomized Block Design (RAKL) consisting of 2 treatment factors and 3 replications. The first factor is lateral branch pruning P0: without pruning, P1: pruning lateral branches 3 WAP, P2: pruning lateral branches 5 MST. The second factor is the dose of NPK fertilizer with doses of N1: 150 kg/ha, N2: 200 kg/ha, N3: 250 kg/ha.

The results showed (1) Pruning lateral branches had a very significant effect on fresh stover, dry stover, crop diameter, crop weight per plant, and crop weight per plot. However, it did not have a significant effect on plant height and number of leaves. (2) NPK fertilizer doses had a very significant effect on fresh stover, dry stover, crop diameter, and crop weight per plant, had a significant effect on crop weight per plot, and had no significant effect on plant height and number of leaves. (3) The interaction between treatments had a very significant effect on fresh stover, dry stover, and crop weight per plant, and had no significant effect on plant height, number of leaves, crop diameter, and crop weight per plot.

Wokół „I koncertu fortepianowego h-moll” op. 79 Raoula Koczalskiego. Geneza i źródła
Authors: Bogula-Gniazdowska Ewa
Published: December 2023

Raoul Koczalski, polski pianista i kompozytor, uczeń Karola Mikulego (wychowanka samego Chopina), zasłynął przede wszystkim jako wirtuoz fortepianu, znakomity wykonawca dzieł Fryderyka Chopina. Mniej znany jest dzisiaj jego dorobek kompozytorski. Tymczasem Koczalski jest autorem bogatej twórczości, obejmującej dzieła różnych gatunków, w tym twórczość fortepianową, symfoniczną, a nawet operową. Jest także autorem aż 6 koncertów fortepianowych, z których najmniej wiadomo było dotąd o jego pierwszym dziele w tym gatunku, Koncercie fortepianowym h-moll op. 79.
Artykuł stanowi prezentację praktycznie pomijanego dotąd w omówieniach na temat twórczości Raoula Koczalskiego, nigdy niepublikowanego I koncertu fortepianowego h-moll op. 79. Zawiera krótkie przedstawienie genezy dzieła w dorobku pianisty i kompozytora, refleksję nad rozwojem jego twórczości kompozytorskiej w kontekście stosunkowo krótkotrwałej edukacji artystycznej, w końcu opisuje mało znane, a niezwykle bogate materiały źródłowe tej kompozycji znajdujących się w zbiorach Staatliches Institut für Musikforschung w Berlinie. Na podstawie tych źródeł umiejscawia koncert w dorobku kompozytorskim Koczalskiego oraz umożliwia jego datowanie.
Muzyka sceniczna Edvarda Griega do „Peera Gynta” w perspektywie historycznoteatralnej
Authors: Partyga Ewa
Published: December 2023

Artykuł zestawia ze sobą wybrane narracje historycznoteatralne i historycznomuzyczne interpretujące rolę muzyki scenicznej op. 23 Edvarda Griega, stworzonej na potrzeby prapremiery Peera Gynta Henrika Ibsena (1876), w recepcji tego utworu i ustanawianiu jego znaczenia. W pierwszej części przedstawiono współpracę amatorskich i profesjonalnych środowisk muzycznych i teatralnych, które tworzyły norweski teatr jako miejsce konstruowania tożsamości narodowej, oraz wprzęgnięte w ten cel tradycje muzyczno-teatralne, ze szczególnym uwzględnieniem popularnego gatunku syngespill. Omówiono także muzyczne doświadczenia Ibsena zgromadzone w trakcie dziesięcioletniej pracy w teatrach w Bergen i w Christianii, które wpłynęły na jego oczekiwania wobec kompozytora. Druga część jest poświęcona formom współpracy Griega ze środowiskiem teatralnym w Christianii. W trzeciej części w centrum uwagi są istotne ogniwa procesu powstawania prapremierowej inscenizacji: list Ibsena do Griega jako świadectwo muzyczno teatralnej wyobraźni pisarza, list Griega do dyrygującego prawykonaniem Johana Hennuma jako dowód troski kompozytora o teatralne działanie muzyki, rola doświadczonego w inscenizowaniu utworów muzyczno-dramatycznych i oper reżysera Ludviga Josephsona jako autora całościowej koncepcji prapremiery, która miała przyciągnąć do teatru szeroką publiczność. W ostatniej części określono czynniki wpływające na performatywną otwartość i siłę oddziaływania muzyki do Peera Gynta stworzonej przez Griega w wielu wariantach i funkcjonującej od początku w rozmaitych kontekstach. Zestawienie historycznoteatralnych i historycznomuzycznych narracji przekonuje, że Peer Gynt Griega jako dzieło artystyczne, fenomen kulturowy i przedmiot refleksji naukowej stanowi materiał, który w nowym świetle mogą ukazać badania o charakterze interdyscyplinarnym. Uzupełnieniem artykułu jest aneks zawierający przekład omawianego w drugiej części listu Ibsena do Griega z 23 stycznia 1874 roku.

Effects of Land Reclamation Activities on Fish Catch Among Fishermen at Merambong Shoal, Johor
Authors: Kamarulzaman Nitty Hirawaty , Jumain Nora Azura
Published: December 2023

The fisheries community is a community that is highly dependent on the fisheries sector, and they usually live near the coastal area.  However, land reclamation activities are conducted in the coastal area for development and urbanization due to the increasing population. Consequently, the land reclamation activities degraded the habitat of the fish and caused a decrease in their productivity. This study investigated the effects of land reclamation activities on fish catch among fishermen. Using convenience sampling, 79 fishermen in the Merambong Shoal were selected, and a structured questionnaire was constructed to get responses from these fishermen. Descriptive analysis, factor analysis, and multiple regression analysis were used to analyze the data. The study revealed that the number of trips, duration of fishermen to catch fish, distance of fishing ground from the coast, number of crew, and government incentives were the factors that affected the fish catch. These factors have significant relationships with the quantity of fish catch, which directly impacts income and, at the same time, affects livelihoods. The role of the government in increasing the monetary incentives and subsidies to improve the fishermen's fishing operations was highly recommended.

This case-control study, conducted at the Hospital USM BestARi unit, aimed to identify the serum metabolic fingerprint among individuals with breast lumps and healthy controls, and to discover potential biomarkers. Serum samples from healthy controls, benign breast lump patients, and malignant breast lump patients were analyzed using proton nuclear magnetic resonance spectroscopy (1H NMR). A multivariate data analysis approach was employed, with the OPLS-DA and clustered heat map techniques effectively differentiating between the three groups. The study revealed significant metabolite variations across the groups and proposed D-glucose, glycerol, and glycine as potential biomarkers for breast cancer diagnosis. Metabolic pathways such as alanine, aspartate, glutamate metabolism, and glycine, serine, and threonine metabolism were implicated. The metabolomics approach coupled with multivariate analysis successfully identified key metabolites leading to group separation and suggested altered metabolic pathways. However, further research and integration with other ‘omics’ technologies are necessary for clinical translation.

The COVID-19 pandemic and its associated containment strategies have significantly impacted the logistics of supplying sexual and reproductive health (SRH) services to adolescents and young adults (AYA) in sub-Saharan Africa (SSA). Studies conducted in the region indicate an increase in sexual activity, particularly among young people, during the pandemic. However, the impact of these changes on their utilization of SRH services remains unclear. This scoping review aims to synthesize the available evidence on the impact of COVID-19 on the SRH behavior and service utilization of AYA. This review focuses on examining the demand and supply of SRH for AYA during the COVID-19 lockdown period (January 2020 – December 2021). Following the Arksey & O’Malley (2005) procedure and the Joanna Briggs Institute (JBI) Reviewer’s Manual (2020), the review encompasses comprehensive search strategies, analysis, and reporting of results. The search for relevant articles was conducted across various databases, including Medline Complete, Africa-Wide, SocINDEX, Academic Search Complete (all through EBSCOhost), Public Health, Social Science & Sociology databases, the Middle East & Africa Database (all through ProQuest), and Web of Science. Articles published between January 2020 and December 2021 were included in this review. The studies discussed in this review shed light on the discrepancies in the demand for and supply of SRH services during the COVID-19 pandemic, exposing a substantial gap in addressing the specific SRH needs of AYA. This review also examines the strategies adopted by countries in SSA to mitigate these effects. Several countries in SSA demonstrated resilience as health providers fulfilled their role, while AYA sought alternatives to mitigate the shortage in the supply chain for SRH services and commodities, often resorting to alternative medicine. The findings underscore the urgency of further research to address the risks imposed by COVID-19 on the utilization of SRH services by AYA in SSA. The evidence presented in this review can inform strategic efforts to ensure the availability and accessibility of SRH services for AYA during any unforeseen emergency or future pandemic.

Published: December 2023

Micro enterprises are believed to be able to thrive in unstable situations because they operate independently and have a relatively small scope. Small and medium-sized business owners must be able to survive in an industry dominated by large and medium-sized companies. To achieve this, they need effective marketing strategies, focusing on service quality and price perception, in order to create customer satisfaction and loyalty. The sustainability of micro and small business owners depends on how well their products can endure. In this study, the third key factor (TKT 3) is active research and development. This may involve analytical studies and laboratory research to physically validate analytical predictions about separate elements of technology. For instance, it could relate to components that have not yet been integrated or those that represent a sample. The study population consists of residents in Tangsel, and sampling is done using purposive techniques. Using the Hair formula, the sample size is rounded to 100 individuals who will serve as research respondents. These respondents will be provided with a Google Form questionnaire for the research.

Objectives from the study This is to describe determinant factors of compliance with ARV consumption for people living with HIV AIDS (PLWHA) at home in Sick Surakarta Central General.
 
Methods: Type study This is a descriptive-analytic approach designed to be cross-sectional. The population is all HIV AIDS patients undergoing ARV therapy maintained at Jalan RSUP Surakarta, with as many as 49 patients. Data collection techniques use total sampling. Data collection is done using a questionnaire for ART compliance (Life Windows Information-Motivation-Behaviorak Skill). Data analysis techniques include univariate and bivariate analysis with the Chi-Square test.
 
Results: Research results show (1) Chi-Square test result information (p = 3.027). (2) Results of the Chi-Square test of motivation (p = 0.776) (3) Chi-Square test results: skills and behavior (p = 2.982). No There is a significant influence between information, motivation, and skills associated with obedience to drug ARVs. (1) Odd Ratio Test Results Information (p = 0.244), Odd Ratio Test Results Motivation (p = 0.420), Nagelkerke's R Square (p = 0.185), or 18.5%.
 
Conclusion: Support family is very influential in influencing obedience to drug ARVs, so officer health must involve families and always give support to patients who receive ARV therapy.

Within group A Streptococcus (GAS), only Streptococcus pyogenes exhibits clinical significance. GAS is typed serologically based on unique surface proteins and critical virulence factors, such as a hyaluronic acid capsule that shields GAS from phagocytosis. The burden of GAS was estimated in the last five years as 14,000 to 25,000 cases of the invasive group A streptococcal disease in the USA with an estimated death from 1,500 to 2,300 cases per year. Early in the summer of 2022 in England, there was more scarlet fever than was anticipated. Early in the current season, the number of notifications rose to unusual heights. The analysis of invasive GAS (iGAS) isolate typing data shows that this season has seen a wide variety of encoding mature M protein (emm) gene sequence types found. Therefore, public health authorities should think about initiatives to increase clinicians’ and the general public’s awareness of GAS infections and to promote their quick diagnosis, molecular testing and antibiotic susceptibility testing, and standard treatment.
Cholesterol de novo biosynthesis: a promising target to overcome the resistance to aromatase inhibitors in postmenopausal patients with estrogen receptor-positive breast cancer
Authors: Coradini Danila , Ambrogi Federico
Published: December 2023

Aim: Cholesterol is an essential component of cell membranes and serves as a precursor for several bioactive molecules, including steroid hormones and isoprenoids. Generally supplied by the bloodstream, the de novo cholesterol biosynthesis is activated in response to an increased cell requirement due to normal tissue remodeling or tumor proliferation. In estrogen receptor (ER)-positive breast cancers, cholesterol biosynthesis may promote and sustain tumor growth and concur with the failure of the treatment with aromatase inhibitors. Methods: In this study, the comparison of gene compared the expression involved in cholesterol biosynthesis was conducted in ER-positive tumors that were responsive and nonresponsive to letrozole; besides, an exploration of their association with genes implicated in estrogen production, the Hippo pathway, and cell cycle control was performed. Results: In responsive tumors, letrozole significantly decreased the expression of five genes [acetyl-coenzyme A (CoA) acetyltransferase 2 (ACAT2), 3-hydroxy-3-methylglutaryl-CoA synthase 1 (HMGCS1), 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), farnesyl diphosphate synthase (FDPS), and squalene epoxidase (SQLE)] crucial for the biosynthetic process. Conversely, in nonresponsive tumors, these genes were unaffected by letrozole but associated with several genes involved in estrogens production [cytochrome P450 family 19 subfamily A member 1 (CYP19A1), hydroxysteroid 17-beta dehydrogenase 2 (HSD17B2), and sulfotransferase family 1A member 1 (SULT1A1)], cell cycle [control cyclin dependent kinase 4 (CDK4) and CDK6], and Hippo pathway [Yes1 associated transcriptional regulator (YAP1) and baculoviral inhibitor of apoptosis (IAP) repeat containing 5 (BIRC5)]. Conclusions: The findings corroborated the notion that the dysregulation of the mevalonate pathway may contribute to the resistance to letrozole and supported the use of statins to contrast this metabolic dysfunction.

Hemangioblastoma are benign, vascularized cranial tumors caused by autosomal dominant inherited von Hippel-Lindau disease or can appear sporadically. This review will investigate current and emerging treatments for cerebral tumors. It will focus on the current and, more importantly, developing hemangioblastoma treatments. Surgical resectioning and radiotherapy are effective treatment options for cerebral tumors, whereas chemotherapies are not commonly used due to their limited ability to penetrate the blood-brain barrier. Recent chemotherapies have shown promise, but further research is needed to determine the efficacy as a treatment for hemangioblastomas. New advances in brachytherapy and immunotherapy are considered promising treatment options for hemangioblastoma. This review aims to offer valuable insights into the latest developments in hemangioblastoma treatments.
Psychology of bipolar depression: revisiting past and present researches, prospects ahead, and moving toward future directions
Authors: Afshari Behrooz
Published: December 2023

Bipolar disorder (BD) is a debilitating psychiatric disorder characterized by recurrent depression, mania, and hypomania episodes. The interaction of psychological, neuropsychological, and neurobiological factors (cognitive, behavioral, and emotional) is implicated in the development and persistence of BD. Accordingly, almost all investigators confirm that BD is the outcome of psychological and genetic interactions. Therefore, researchers should consider various factors in the psychopathology and psychotherapy of BD. This selective review first reviews research on these factors, then points to a variety of therapeutic methods for BD [interpersonal and social rhythm therapy (IPSRT), cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), mindfulness-based cognitive therapy (MBCT), and family-focused therapy (FFT)], and finally suggested a new comprehensive integrated model for the assessment and therapy of BD.
