Introduction. The results of study of children with caries provide information on the condition of the teeth and oral hygiene as well as allow to identify the needs for dental care. Still the current problem seems to achieve the expected reduction in dental caries. Treatment of caries of deciduous teeth is not widespread. Aim. Annual observational study the prevalence and intensity of dental caries and oral hygiene status of children in Warsaw under six years of age, presenting every three months for fluoride prophylaxis. Material and methods. The study included 81 children under six years of age. Dental health and hygiene was evaluated in a preliminary study and every 3 months for a period of one year. The average number of dmft, dmfs, their constituent, DI-S index and treatment of dental caries index. The results were analyzed using the chi-square test. Results. The prevalence of caries in the preliminary test in the study group determined to be 75%, in the final examination ? 89%. The average value of the dmft index increased from 5.14 ± 4.25 to 6.99 ± 4.68 and dmfs 10.14 ± 10.59 to 14.98 ± 13.94. The average number of teeth and surfaces with caries was 2.46 ± 3.23 and 4.44 ± 6.92 respectively and was slightly higher in the final study (2.65 ± 2.70 and 4.86 ± 4.98). The average number of teeth and the surface removed increased twice, from 0.47 ± 1.44 and 2.05 ± 6.21 in the preliminary test to 0.93 ± 1.86 and 4.17 ± 8.27 in the final study (p < 0.001). Favorable trend was statistically significant increase in the average number of teeth and the surface of the fillings of 2.21 ± 2.57 and 3.64 ± 4.73 in the preliminary test to 3.41 ± 2.56 and 6.88 ± 5.78 in the final study and the ratio of treatment from 0.49 ± 0.39 to 0.56 ± 0.32. In the preliminary test, the mean DI-S was 1.20 ± 0.71, after one year 0.81 ± 0.64 (p < 0.001). Conclusions. The results indicate the high intensity of caries decay and neglect of hygienic habits and treatment and the beneficial effect of individual fluoride prophylaxis and regular dental visits.

Background and objectives: Aortic valve and aortic vascular disorders represent a subset of cardiovascular conditions that can lead to heart failure. Aortic valve diseases, such as aortic stenosis or regurgitation, and aortic vascular diseases, including aortic aneurysms and aortic dissection, can contribute to impaired cardiac function and increase the risk of heart failure. This study aims to investigate the risk of heart failure in patients with aortic valve and aortic vascular disorders within 30-days of admission in the Intensive Care Unit (ICU). Methods: Patients from a US-based critical care database (MIMIC-III) who developed heart failure in the ICU within 30 days of follow-up were included. Two predictive models, XGBoost and logistic regression, were developed and evaluated using ROC, sensitivity, specificity, and F1 measure. The dataset was split into training and testing samples in an 8:2 ratio. Results: Out of 2,871 patients analyzed, 1,062 (37%) developed heart failure in the ICU during the 30-day follow-up. Key predictors of heart failure included creatinine, phosphate, age, COPD, INR, diabetes, CAD, magnesium, atrial fibrillation, and hyperlipidemia. The logistic regression model outperformed XGBoost with (AU-ROC, 0.78 vs. 0.77, respectively). Conclusions: This study demonstrates the potential of machine learning techniques to enhance predictive modeling in critical care research. It provides valuable insights into heart failure risk in patients with aortic valve and aortic vascular disorders admitted to the ICU.

Published: January 2024

The total photon economy of a molecule/material is a measure of how light input is converted to light and heat output across energies and timescales. We describe a technique, Fluorescent Optical Cycling (FOC), which allows for simultaneous observation of prompt and delayed emission during and after multiple pulsed excitation, ultimately granting access to multi-state photophysical rates. We exercise control over the excitation pulse train, which allows us to “optically shelve” long-lived intermediate states without the use of diode or flashlamp excitation. By recording all photon arrival times in the visible and shortwave infrared, we can simultaneously resolve fluorescence, phosphorescence, and singlet oxygen sensitization in a single experiment. We use FOC to examine the photophysics of dual emitting bis(di-R-phosphino)alkanethiophene-pyridine-platinum ([Pt(thpy)(dppm)]+) under different solvation conditions, revealing changes in intersystem crossing and phosphorescent rates induced by the external heavy atom effect. Coupling FOC with Decay Associated Fourier Spectroscopy (DAFS), we demonstrate simultaneous correlated spectral and lifetime data in this dual emitting complex. Finally, FOC combined with superconducting nanowire single photon detectors (SNSPDs) allows us to observe the shortwave infrared region (SWIR) phosphorescence of singlet oxygen sensitized by Rose Bengal. Overall, FOC provides a powerful tool to simultaneously study multiple photophysics across timescales, even in weakly populated electronic states.
Impact of an Ionic Liquid Solution on Horseradish Peroxidase Activity
Authors: Chatterjee Shubham , Nochebuena Jorge , Cisneros G. Andrés
Published: January 2024

Horseradish peroxidase (HRP) is an important enzyme for industrial purposes due to its ability to oxidize pollutants from wastewater. A previous report indicated that peroxidases can have up to a 20% increase in enzymatic activity in an aqueous solution of 0.26 M 1-Ethyl-3-methylimidazolium ethyl sulfate ([EMIm][EtSO4]) at neutral pH. However, the atomistic details of how the solution affects peroxidase activity remain elusive. In the enzymatic landscape of HRP, an intermediate termed Compound II (Cpd II) plays a key role and involves a histidine (H42) residue that may take different protonation states. Cpd II displays structural versatility, existing as oxo-ferryl (2a) or hydroxo-ferryl (2b(FeIV)) forms, where 2a is the predominantly observed form in experimental studies. Intriguingly, the ferric 2b(FeIII) form seen in synthetic complexes, has not been observed in HRP. Here, we have investigated the structure and dynamics of HRP in pure water and aq. [EM-Im][EtSO4] (0.26 M), as well as the reaction mechanism of Cpd II catalyzed conversion of 2a to 2b using polarizable molecular dynamics (MD) and quantum mechanics/molecular mechanics (QM/MM) calculations. When HRP is solvated in aq. [EMIm][EtSO4] a significant reduction in the fluctuation of residues 70, 71 and 74 is observed. This reduction is due to the migration of EtSO4– ions close to this region, which results in structural changes leading to the dehydration of the active site. These structural changes in the active site orient H42+ directly over the ferryl moiety, leading to a direct proton transfer with a significant energy reduction in the reaction barrier. Conversely, in neat water, the reaction for 2a to 2b follows the previously reported mechanism where H42+ transfers a proton to the ferryl moiety via an ordered water in the active site. We further investigated an alternative path with the deprotonated form of H42, where the mechanism shifts to hydrogen atom transfer (HAT), with similar reaction barrier differences between the aqueous and aqueous/IL mixture, albeit with significantly higher relative barriers. Analysis of the electric fields at the active site indicate that the aq. [EMIm][EtSO4] medium facilitate the reaction by providing a more favorable environment compared with the system solvated in neat water. Overall, our calculations provide atomic-level insights that help explain the observed improvement in activity for peroxidases in IL solution, and underscore the importance of favorable electric fields in the active site to promote catalysis.

The discovery of multinary Sn(II)-containing oxides has been severely limited by a lack of understanding of the factors leading to their thermodynamic stability, e.g., chemical compositions and structure types, as well as by the absence of productive synthetic routes. The relatively few reported Sn(II)-O-M (M = early transition metal cation) solids frequently decompose at moderate to low temperatures. Herein, a large-scale predictive modeling approach was used to assess the structural factors yielding their enhanced thermodynamic stability. This has resulted in ten predicted new Sn(II)-containing oxides that are proposed to fall within reasonable synthetic limits. Increasing stability was found for structures possessing smaller amounts of Sn(II) with local asymmetric coordination environments allowing expression of its stereoactive lone pair. As a test of these results, synthetic efforts to prepare one of the proposed compounds starting from BaLa4Ti4O15 yielded the predicted noncentrosymmetric layered perovskite SnLa4Ti4O15 (SLTO). The new SLTO crystallizes with hexagonal plate-shaped morphologies in the polar P3c1 space group (No. 158), as confirmed by Rietveld refinements of powder X-ray diffraction data and second harmonic generation activity. Full Sn(II) substitution was confirmed by 119Sn Mössbauer spectroscopy, SEM-EDS, and X-ray photoelectron spectroscopy. UV-vis diffuse reflectance data confirmed that SLTO has a visible-light bandgap of ~2.4 eV and is thus predicted to be promising photocatalyst for solar energy conversion. After loading its surfaces with a Rh/Cr2O3-CoOx dual-cocatalyst, SLTO is the first Sn(II)-containing oxide to show activity for overall water splitting into H2 and O2 with an apparent quantum yield of ~21.7%. Thus, these results highlight the synergistic combination of chemical intuition, predictive modeling, and synthetic design in the synthesis of new Sn(II)-containing oxides for promising optical properties and photocatalytic activities for water splitting.
No Country for Old Men

Immigration policies are aimed at young-to-middle-aged people, for good reasons. The exceptions are parental and grandparental immigration programs, designed to reunite yesterday’s immigrants and their young children with the (grand)parents who still live in the country of origin. (Grand)parental immigration has been an unquestioned facet of immigration law for the last century and a half. Elderly people are the least threatening immigrants: they rarely commit crimes, they are not conduits for further immigrant family members, and they are unlikely to fundamentally change the culture of the destination state. Yet the last few decades have seen an unprecedented and mostly unremarked assault on parental and grandparental immigration, with some rather shoddy economics as the only reason. Quotas have been lowered, required sponsorship amounts have been raised, health conditions have been made stricter, and family structures have been added to the list of criteria. This article looks at the tightening of immigration rules since the 1970s in three types of immigrant-receiving countries: traditional settler states, modern settler states, and liberal states which seek to discourage immigration. The article concludes that reasons, whether legal, political or economic, are lacking in both quantity and quality. The growing restrictions on elderly immigration are unjust and senseless, and should be reversed.

Published: January 2024

Sexual activity among adolescents is increasingly alarming; the results of a national survey identified about 4.5% of teenage boys and 0.7% of teenage girls have had sexual intercourse that triggers unwanted pregnancies. This study analyzed the influence of risky sexual behavior factors in adolescents on the incidence of unwanted pregnancy. This research is a secondary data analysis sourced from Indonesian Demographic and Health Survey (IDHS) data in 2017 using a cross-sectional design. The study sampled 15-24-year-olds who had sexual intercourse with as many as 1532 people. Data were analyzed univariately while  bivariate analysis using Chi-Square test and multivariate analysis with logistic regression test of the risk factor model. The results showed unwanted pregnancy occurred in 8.6% of adolescents who had a history of having sexual intercourse. In addition, it will be 4.5 times greater risk of unwanted pregnancy occurred in adolescents who performed risky behaviors such as fingering and stimulating each other after being controlled by variable confounding age and age when first having sex (PR = 4.570). Therefore, equal access to reproductive health education is needed both in educational institutions and in the community as an effort to prevent unwanted pregnancy.

Abstract

 

One of the development activities carried out by the Government of Bulukumba Regency is renovating the Tanete Market in Bulukumpa District, Bulukumba Regency. The market was developed with a total deve-lopment area of ​​9918 m2. This market is predicted to have very good future prospects, because it is located in a very strategic location. However, it is estimated that the impact of developing Tanete Market will be to increase the traffic load on the roads around the market. The aim of this study is to analyze the impact of the development of the Tanete Market, both during construction and post-operation, on the performance of Jalan Poros Bulukumba–Sinjai, where the market is located. Primary data was obtained by surveying vehicle volume, vehicle speed, and road characteristics. Meanwhile, secondary data is in the form of vehicle growth data. Traffic performance measurements were carried out using the 2017 Indonesian Road Capacity Manual. This study shows that the development of Tanete Market does not have a significant impact on traffic performance on the road where the market is located. Jalan Poros Bulukumba–Sinjai still has Service Level A, both during cons-truction and after the operation of Tanete Market.

This investigation was conducted to appraise the interrelation between the influences of phosphorus deficiency on vitamin D and parathyroid hormone and assessment its effect on the liver and muscular markers. These investigations were carried on forty adult female water buffaloes divided into three groups according to serum phosphorus level. The first group contained ten apparently clinically healthy buffaloes and used as a control. The second and third groups were fifteen buffaloes for each suffered from moderate or severe signs of phosphorus deficiency (signs include anorexia, emaciation, weakness and paleness mucous membranes in the two groups in addition to red urine in the third one). Phosphorus level showed a significant decline in sub-clinical cases and highly significant decrease in clinical cases. Parathyroid hormone was significantly decline in sub-clinical and clinical cases, while active form of vitamin D wasn’t changed in sub-clinical cases and significantly decline in clinical cases when compared with normal control. Creatine phosphokinase significantly rise in clinical cases. Malondialdehyde was significantly increased while glutathione peroxidase was significantly decreased in both moderate and severe cases. This conclude that phosphorous deficiency causes lessening in parathyroid hormone, 25 hydroxycholecalciferol (25 (OH2) D3 and increasing in the markers of oxidative stress and muscular damage which exaggerated by increasing in the deficiency. So, addition of vitamin D supplementation and antioxidant should be conservative treatment regime.

Camel minced meat is widely used in the world especially they were used to produce low-cost protein when compared with other animals. Therefore, the current study aimed to assess the effects of chitosan, rosemary essential oils, and sodium lactate on the organoleptic, chemical, and bacteriological quality of camel minced meat during refrigerated storage at 4°C. Twenty kg of camel meat (round meat) were obtained 24 hours after slaughter. The meat was minced and classified into four groups; untreated control and three treated groups (0.2% rosemary oil, 2% sodium lactate and 1% chitosan), which was kept under chilling conditions at 3±1° C and examined at different storage periods (zero-time, 3rd, 5th and 7th days of storage). The organoleptic, chemical, and bacteriological quality of minced meat was assessed. The surface discoloration was noticed on the 3rd day of the control group, but all treated groups retained their normal color especially 1% chitosan group, which maintained the highest value of redness. The sodium lactate group at 7th day of storage had pH, total volatile basic nitrogen (TVB-N mg/ 100 g) and thiobarbituric acid (TBA mg/kg) of 6.13, 14.3 and 1.08, respectively, while they were 6.37, 16.4 and 0.82 of rosemary group and 6.29, 15.64 and 0.72 of chitosan group, respectively. Spermine, spermidine, putrescine and tyramine were detected without significant differences in all examined groups but cadaverine and tryptamine were significantly low in all groups when comparing with the control group. Sodium lactate exhibits a great effect against bacterial growth on the 7th day of chilling by minimizing the bacterial load to be 5.95, 3.44 and 3.21 log10 CFU/g for psychrotrophic, Enterobacteriaceae and pseudomonas, respectively with original counts of 6.98, 4.51, and 4.29 log10 CFU/g, respectively. The current study concluded that the quality of camel minced meat could be enhanced by adding rosemary, sodium lactate, and chitosan, but sodium lactate was the best in controlling bacterial proliferation and biogenic amine formation.

Antimicrobial resistance (AMR) is a growing threat to human and animal health, reducing the ability to treat bacterial infections and consequently the risk of morbidity and mortality caused by resistant bacteria. The World Health Organization (WHO) has predicted 10 million deaths by 2050 due to infectious diseases. A considerable increase in the number of pathogens harbor multidrug resistance genes, seemed to be arising from the extensive use of antimicrobial agents for medical issues particularly in food-producing animals, along with the many pathways of their release into the environment. The emergence of multidrug-resistant (MDR) microorganisms has threatened the longstanding use of antibiotics, which were globally used to save millions of lives. The evolution and spread of AMR have a great adverse impact on human beings. Naturally, bacteria have the genetic ability to acquire and spread resistance to therapeutic agents. Therefore, the major challenge has been to limit the extensive and the inappropriate overuse of antibiotics, in addition to finding new drugs either from synthetic or natural origin to counter microbial resistance by acting on the specific target responsible for MDR. To overcome the crisis of antimicrobial drug resistance, WHO has issued several guidelines on the use of antimicrobial agents, such as preserving antibiotics that are important for human health and preventing their usage in agriculture. Several therapeutic approaches like vaccines, antimicrobial peptides, bacteriophages, and nanotechnology, along with phytochemicals and herbal medicines, are applied in vitro and in vivo experiments and are supposed to be suitable candidates for antimicrobials to combat the rapidly evolving AMR. In this review, we will discuss the causes of this resistance, types, its spread between ecosystems, super-resistance associated with superbugs like E. coli, and the possible therapeutic approaches against MDR pathogens.

Chicken meat represents an importance source of animal derived proteins, vitamins, and minerals. However, chicken meat might act as a potential source of human exposure to foodborne pathogens such as Staphylococcus aureus (S. aureus) and Salmonella species. The objectives of the present study were first to investigate the prevalence rates of S. aureus and Salmonella species in the retailed chicken breast and thigh muscles at Zagazig city, Egypt. Second, serological identification of the isolated bacteria was followed. Third, screening of S. aureus enterotoxin coding genes (sea, seb, sec, sed, and see) and methicillin resistance (mecA) gene, as well as Salmonella virulence associated genes including Salmonella hyper-invasive locus (hilA), and Salmonella enterotoxin (stn) was done using PCR. Thereafter, the inhibitory effects of Nigella sativa, and rosemary essential oils were investigated against S. aureus, and Salmonella Typhimurium. The obtained results revealed isolation of S. aureus from the examined breast and thigh muscles at percentages of 23.3%, and 26.6%, respectively, whereas percentages of Salmonella spp. isolation from both samples were 33.3%, and 16.6%, respectively. Four Salmonella serotypes namely, S. Typhimurium, S. Enteritidis, S. Kentucky, and S. Anatum were further identified. The recovery rates of S. Typhimurium from breast and thigh muscles were 23.33% and 13.33%, respectively followed by S. Enteritidis (3.33% each). Staphylococcus enterotoxin genes (sea, and see), and mecA gene were detected in S. aureus isolates. Besides, Salmonella hilA and stn genes were also detected in Salmonella Typhimurium isolates. Nigella sativa and rosemary essential oils at 0.1%, and 0.5% could significantly reduce S. aureus, and Salmonella Typhimurium in chicken breast meat.

Semen analysis is a valuable approach to assess stallion fertility. Many factors, including the age of the stallion and the season of year have been shown to influence semen quality. Therefore, the current study aimed to evaluate the influence of stallion’s age and season on the potential semen parameters and sperm morphology in Arabian stallions. A total of 108 ejaculates were collected using artificial vagina throughout the year from nine Arabian stallions aged 4-22 years, divided into three groups according to their ages; Group I (4-6 years), Group II (8-11years), and Group III (15-22 years). The ejaculates were analyzed immediately after collection for macroscopic and microscopic parameters using computer-assisted sperm analysis (CASA). Statistical analysis was applied to study the effect of the age of the stallion and season of semen collection on semen parameters. Our results showed a clear age-based differences (P < 0.05) with stallions aged from 4 to 11 years produce higher semen quality especially in sperm count, livability, motility and normal sperms compared with old stallions (15-22 years). Moreover, old stallions showed higher (P < 0.05) sperm abnormalities especially the secondary defects. The semen volume increased (P < 0.05) in the spring, and sperm concentration was higher (P < 0.05) in the winter and autumn, while, no significant variation in total sperm number between different seasons. Moreover, the livability, motility, normal sperms and progressive sperm motility were higher (P < 0.05) in hot season (breeding season) compared with cold season, but abnormal sperms were lower. These data suggest that, older stallions (15-22 years) produce ejaculates of larger volume but the motility, viability, and abnormalities percent were better in ejaculates collected from stallions aged 4-11 years. Ejaculates collected during spring and summer showed better characteristic than that collected during autumn and winter.

In a complete randomized design, the birds were weighted and randomly assigned to six groups from T1 to T6 treated with different levels of FSBM as 0%, 2%, 4%, 6%, 8%, and 10 % respectively. For a treatment, five replicates with four chicks in each one were used. Results showed a significant increase (P < 0.05) in the body weight (BW) in T2, T5 and T6 group which increased by 16.76%, 15.77% and 17.96% than the control group, respectively. Birds fed diet contain 2% FSBM had the best feed conversion ratio (FCR) as it improved with 12.43% than the control. There was a significant increase (P < 0.05) in the abdominal fat%, liver% and heart% in T6 and no significant differences were detected in other groups compared to the control. Also T3 showed a significant increase in intestine% compared to control. The economic efficiency, net profit and total return were significantly (P < 0.05) higher in T2, T3, T5, and T6 than control group. There was a significant (P < 0.05) decrease in the number of coliform bacteria in all groups compared to the control. But there was a numerically increase in the number of lactic acid bacteria in T2 and T6 than the control. There was a significant increase in the cholesterol level in a level dependent manner. No significant differences in total protein and albumin were detected in T2 compared to control group. Collectively, our results revealed that 2% FSBM had benefit effects on growth performance of birds with a good economic efficiency.

Pamięć miasta w Mȕnchhauseniada Jerzego Limona
Authors: Kubińska Olga
Published: January 2024

Artykuł omawia pierwszą powieść Jerzego Limona, Mȕnchhauseniada (1980), osadzoną w powojennym kurorcie nadmorskim, który z miasta Niemców, Kaszubów i Polaków został miastem przesiedleńców ze Wschodu i musi przenegocjować swoją nową tożsamość. Powieść, analizowana w kategoriach badań nad pamięcią, ukazuje poszukiwania adekwatnego gatunku literackiego, konwencji języka, które oddadzą procesy historyczne zachodzące po masowych przesiedleniach w efekcie II wojny światowej. Zderzenie paradokumentalnego charakteru opisów, powieści szkatułkowej, elementów pikarejskich, czy wręcz narracji rozpychających ramy powieści obyczajowej, zdają się wiązać z niestabilnością czasów, w jakich powieść została umieszczona, jak również wydarzeń historycznych i społecznych w mieście, które stanowi (a)mimetyczne odwzorowanie Sopotu czy Gdańska po II wojnie światowej.W efekcie powieść zyskuje, gdy czytać ją również w kategoriach realizmu magicznego, który narodził się w niestabilnej Europie po I wojnie światowej, czyli w Republice Weimarskiej w 1925 roku.

Published: January 2024

We have shown a spectral inclusion between a different spectrum of a C0-quasi-semigroups in [9]. Precisely for Saphar, essentially Saphar, quasi-Fredholm, Kato and essentially Kato spectra. In this paper, we extend these results for a C-quasi-semigroups (regularized quasi-semigroups) where C is a bounded injective operator.

O crescente e acelerado uso de tecnologias de automatização com Inteligência Artificial para o tratamento e análise de dados faz surgir uma preocupação com as regulamentações em torno da privacidade e do uso desses dados. Objetivou identificar os trabalhos relacionados à regulamentação da Inteligência Artificial para o tratamento de dados, no contexto da Ciência da Informação. Para tanto, foi realizada uma busca sistemática sobre o tema em bases de dados da área. O levantamento bibliográfico embasou uma análise quantitativa desta pesquisa e permitiu uma análise qualitativa das publicações encontradas. Constatou-se que as publicações sobre o tema dentro do contexto da Ciência da Informação são recentes e, em sua maioria, publicadas no Brasil, apesar de haver uma preocupação mundial em torno da regulamentação do uso de dados por empresas e instituições. Também foi possível identificar uma crescente preocupação com as regulamentações no uso de processos automatizados que utilizam Inteligência Artificial na coleta e, principalmente, no processamento dos dados, justificado pela massiva quantidade de dados coletados (Big Data), e pela expressiva melhoria dos resultados gerados por essas tecnologias. Esta pesquisa evidencia que há necessidade de melhorias nas regulamentações que tratam de privacidade e proteção de dados, ampliando seu escopo para as tecnologias que usam Inteligência Artificial, levando em conta a segurança, a transparência e a ética dos dados tratados, sem interferir no avanço tecnológico proporcionado por essas tecnologias.
