A Gecko-eye View of Naturalistic Enclosures

Published on: 1st December, 2023

Naturalistic enclosures have become a popular exhibition technique for zoos, and reptiles and amphibians are regularly housed in these exhibits. While a considerable sum of research indicates that visitors prefer naturalistic exhibits, there are fewer studies documenting the behaviour and welfare of animals housed under these conditions. This study investigated the impact of a naturalistic enclosure on the behaviour of the turquoise dwarf gecko (Lygodactylus williamsi), and the welfare perceptions of visitors. When kept under naturalistic enclosures, dwarf geckos were seen to bask (p = 0.022), and engage in inactive behaviours (p = 0.001) significantly less frequently. A non-significant decrease was also seen in locomotion | (p = 0.074). While time spent hidden remains a confounding factor for behavioural analysis, the study indicates that when provided with hiding opportunities, L. williamsi may spend a considerable amount of time hidden from the public. Questionnaire analysis revealed that 84.6% of individuals believed that naturalistic enclosures demonstrated better welfare. Additionally, individuals who had previously owned a reptile were more likely to identify that areas to hide, enrich, and mimic the natural environment were important aspects of enclosure design. While the actual benefits of naturalistic enclosure design cannot be fully addressed by this study, this work suggests that visitors tend to inherently believe that naturalistic enclosures facilitate better welfare, even if they are not aware of the natural environment of the species being housed. This requires keepers to consider both aspects of functionality and enclosure relevance when designing exhibits for herptiles.

Acceptance of Oral Sex among High School Students in Budapest: Incidence and Correlates

Published on: 4th December, 2023

Introduction: Adolescents and young adults often engage in oral sex. However, the factors affecting the development of agreeing with oral sex are not clear enough.Objective: We aimed to assess the degree of agreement with oral sex among high school students and to search for background factors affecting this.Material and method: We conducted a quantitative cross-sectional study among 157 females and 38 male high school students over the age of eighteen by using an anonymous, paper-based, multiple-choice, self-administered questionnaire. For statistical analysis, we used descriptive statistics, two-sample t-tests, and Spearman rank correlation. Results: Of the respondents 67.9% were sexually active and 31.6% of them had more than one sexual partner. Of males 97.1% and of females 84.9% agreed with accepting oral sex. Degree of agreement with oral sex was higher in those who had had partnered sexual experience, and in those females who more frequently met close friends outside of school. Most participants were not in a current relationship with a partner, and for those who were, its duration did not affect the degree of accepting oral sex. The degree of agreement with the proficiency in male sexuality, and the degree of agreement with those dimensions of sexuality that most expressed the sexual drive and the desire to gratify it with the partner showed the strongest positive correlation with the degree of agreement with oral sex. In addition, the degree of agreement with the items of expressing sexual openness showed correlations with the degree of accepting oral sex. Conclusion: The degree of agreement with oral sex is high among high school students. Among the factors influencing this, the intensity of meeting friends seems to be important. We therefore recommend that the schools improve sex education in groups, highlighting the risks of oral sex, to reach the target individuals and their friends as well as their potential partners.

Management of Chocolate Spot Disease in Faba Bean Plants by using Biological Control Means

Published on: 4th December, 2023

Background: Faba bean (Vicia faba L.) is one of the most important grain legume crops in Egypt and many other countries of the world because the seeds offer a low-cost source of protein, lysine, carbohydrates, minerals, and vitamins. Chocolate spot disease is a stress-related fungal disease produced by Botrytis fabae that causes plant damage, limits photosynthetic activity, and reduces yield. Results: Trichoderma atroviride greatly reduced mycelial growth by 90.00% in vitro, followed by T. harzianum (86.67%) and T. album (83.89%) on average. In vivo, all studied antagonists dramatically reduced Botrytis fabae disease incidence and severity in both seasons 2021/22 and 2022/23. T. atroviride showed the highest efficacy bioagent (73.55 and 85.15%), followed by T. harzianum (72.55 and 81.22%), in controlling B. fabae of faba bean plants in both seasons. In addition, the results also showed that all tested biological treatments had an impact on yield components and increased levels of chlorophyll, protein%, phenols, flavonoids, Peroxidase (PO), polyphenol Oxidase (PPO), chitinase, and -1, 3-glucanase activities compared to control treatment in both seasons. In this regard, spraying T. atroviride showed the highest efficacy as a bioagent, followed by T. harzianum. Contrary, T. hamatum showed the lowest efficacy compared to other treatments in both seasons. Conclusion: This investigation was carried out to determine the effectiveness of several different antagonists, i.e., T. album, T. atrovirde, T. hamatum, and T. harzianum (30 x 106 spore/ml), Blight Stop, and Bio Zeid, for controlling Botrytis fabae on bean plants and evaluating their effect on yield parameters, components, and quality.

Stable COPD Picture through Exhaled Breath Condensate, Questionnaires and Tests. A Proof of Concept Study

Published on: 5th December, 2023

Background: Changes in lung structures persist in stable Chronic Obstructive Pulmonary Disease (COPD), but their correlation with the clinical picture remains unclear. The purpose of this study was to assess the stable COPD picture via the relationship between exhaled breath condensate (EBC) particle concentration and the Saint George Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT), and six-minute walking test (6 MWT). Methods: 12 stable COPD and 12 healthy subjects participated in the study. The EBC was collected with Rtube and analyzed using the Accusizer FxNano. Particle concentration was measured and correlated with the findings of the tools used to assess the health status and functional profile of COPD. The results’ analysis was performed with the Spearman’s test and the Mann-Whitney U - test.Results: The COPD group presented a worse picture of health status and functional profile compared to the healthy group. Correlations were observed between components of the SGRQ and CAT. The two groups presented similar levels of EBC particle concentrations, but the number of small particles was higher in COPD subjects. A correlation of the EBC particle concentration with the activity and total score of the SGRQ was only observed in the healthy group. Conclusion: The total particle number was similar in the COPD and healthy groups. A few correlations between the EBC particles and tools used were also observed. The use of EBC particle concentration to monitor COPD status cannot be claimed with confidence because of the small sample size. Further research is necessary, particularly in large-scale groups.

Characteristics of Juvenile Sex Offenders in Poland

Published on: 8th December, 2023

According to statistical data in Poland, sexual acts of minors account for about 3% of all criminal acts committed by minors and nearly 20% of all acts from the catalogue of crimes against sexual freedom and morality. The main objective of the study was to attempt to develop and present characteristics of minors who commit rape with particular cruelty. Taking into account the way the perpetrators act, the motivational background, and the circumstances of the crime. In particular, attention was paid to specific individual and family characteristics. Because it is not clear whether juvenile sex offenders are different from non-sex offenders. The aim of this article is an attempt to capture individual, family, and environmental differences. The study was also intended to provide information about who the victims are. The study was conducted on the basis of empirical material from court cases in which the basis of liability was Article 197§4 of the Penal Code, and the perpetrators or accomplices of the acts were minors who at the time of the act were over 15 years of age but under 17 years of age. The research material consisted of court case files that had been finally completed, including forensic psychological opinions prepared by court experts. Cases from 2015-2020 were analysed. The obtained results allowed us to capture some specific features of families in which minors were brought up and the characteristics of juvenile sex offenders themselves. This article raises the difficult issue of juvenile responsibility for sexual crimes and indicates areas in which it is necessary to regulate interactions and areas of possible preventive impacts.

Screening of Auxin-like Substances among Synthetic Compounds, Derivatives of Pyridine and Pyrimidine

Published on: 12th December, 2023

The effect of known synthetic compounds Ivin (N-oxide-2,6-dimethylpyridine), Methyur (sodium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine), Kamethur (potassium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine) and new synthetic compounds, derivatives of pyrimidine (No. 1 - 7) on the rooting of isolated stem cuttings of haricot bean (Phaseolus vulgaris L.) variety Bilozernaya was studied. The growth regulatory activity of synthetic compounds Ivin, Methyur, Kamethur, and synthetic compounds, derivatives of pyrimidine (No. 1 - 7) was compared with the activity of auxins IAA (1H-indol-3-yl)acetic acid) and NAA (1-naphthylacetic acid). The conducted studies showed that the regulatory effect of synthetic compounds Ivin, Methyur, Kamethur, and synthetic compounds, derivatives of pyridine (No. 1 - 7) on the rooting of isolated stem cuttings of haricot bean was similar to the auxins IAA and NAA. The synthetic compounds Ivin, Methyur, and Kamethur, and synthetic compounds, derivatives of pyrimidine (No. 1, 4, 5, and 7) showed the highest auxin-like activity. The indicators of the total number of roots (pcs) and total length of roots (cm) obtained on isolated stem cuttings of haricot bean immersed in a water solution of synthetic compounds Ivin, Methyur, Kamethur and synthetic compounds, derivatives of pyridine (No. 1, 4, 5 and 7), used at a concentration of 10-7 M, statistically significantly exceeded similar indicators obtained on control isolated stem cuttings of haricot bean immersed in distilled water. The practical use of synthetic compounds Ivin, Methyur, Kamethur, and synthetic compounds, derivatives of pyrimidine (No. 1, 4, 5 and 7) is proposed to improve the vegetative propagation of haricot bean plants (Phaseolus vulgaris L.) and other plant species of the family Fabaceae by stem cuttings.

Recommendations for Measurement of Bodybuilding Internal Training Load by eTRIMP Method

Published on: 14th December, 2023

Currently, analysis of training data metrics has become increasingly important in characterizing high throughput. In fact, in bodybuilding, the RPE (rate of perceived exertion) assessment is the metric commonly used to calculate training volume. Therefore, this study demonstrates another way for bodybuilding athletes to evaluate their training through heart rate using the TRIMP (training impulse) method proposed by Edwards to analyze the intensity of a given training model. For this athlete, it is important to stay most of the time outside heart rate zone 1, not have more than 10% of total training time in zone 5 and contain the largest proportion of total training time in zones 2, 3 and 4.

Automatic Hand Features Extraction for Forensic Purposes

Published on: 13th December, 2023

This work describes a low computational cost image processing methodology for the identification of hand features for forensic applications – like height, gender, and ethnicity for suspect inference. The proposed methodology provides an adequately tailored sequence of image and geometrical processings on pictures of hands based on critical points like fingertips, finger valleys, and palm centers. As a result, we present the automatic measurements taken on 416 images compared with actual measurements from a manual caliper. The proposed approach leads to a 93.16% correlation (p - value < 0.05) related to the caliper, demonstrating the effectiveness of the technique.

Rejuvenation of Ovarian Function after Autologous Platelet Lysate Injection: Promising Evidence from Confirmed Cases

Published on: 13th December, 2023

Intraovarian injection of autologous Platelet Lysate (PL) can be considered a potential therapeutic strategy for ovarian function rejuvenation. Especially, in women diagnosed with Poor Ovarian Response (POR) or Primary Ovarian Insufficiency (POI), the exogenous administration of the autologous platelet-derived growth factors, influence positively the regulation of the serum Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), and Anti-Mullerian Hormone (AMH) and Estradiol (E2). Therefore, the evaluation of the serum levels of the aforementioned hormones was performed on 10 participants with a mean age of 43 ± 4 years diagnosed with POR or POI, who received intraovarian PL injection monotherapy. The monitoring of the serum hormone levels was performed for 3 months. The results of this study clearly showed that all participants were characterized by elevated levels of FSH and LH and reduced levels of E2 and AMH, prior to the PL injection. However, the levels of all hormones started to change after the 1st month of follow-up monitoring. Moreover, 40% of the participants conceived successfully either by natural way or after in vitro Fertilization (IVF). Considering these, the intraovarian injection of autologous PL exhibited promising evidence regarding the altering of hormone levels at physiological values. Moreover, the contained PL growth factors were implicated in angiogenesis promotion and also in toleration of the inflammatory microenvironment, regulating positively ovarian function. In conclusion, the intraovarian autologous PL injection is considered a safe, effective, and tolerable therapeutic strategy in women with POR or POI. Moreover, the results of this study were very encouraging, especially for the women with infertility issues, who want their genetic offspring.

Forensic Comparison of Textile Fibre for Identification using X-ray Diffraction Technique

Published on: 19th December, 2023

This study delves into the forensic examination of textile fibers for identification through the application of the X-ray diffraction (XRD) technique. With the textile industry producing an array of materials, both natural and man-made fibers, the need to distinguish between them for forensic purposes becomes paramount. The primary objective of this research is to identify unique characteristics in fiber samples, differentiating between branded and non-branded company textiles. The focus is placed on fresh, unused cloth fibers obtained directly from shops. The study encompasses two broad categories of fibers: natural (such as cotton, silk, and wool) and man-made (including nylon, rayon, and polyester). Samples from both branded and non-branded textiles undergo analysis using XRD, a sophisticated method capable of revealing the crystallographic structure of materials. Results obtained from the XRD analysis unveil intensity peaks at various levels and degrees, providing distinctive patterns for individualization. Even within the same fiber category, such as polyester and cotton, discernible differences in intensity peaks facilitate the identification process. This research contributes to the advancement of forensic techniques by offering a reliable means of identifying textile fibers. The utilization of XRD not only allows for the differentiation between natural and man-made fibers but also enables discrimination among textiles produced by different companies. The implications of this study extend to forensic investigations, where the ability to precisely identify fibers can provide valuable evidence in criminal cases involving textiles.

Success, Survival and Prognostic Factors in Implant Prosthesis: Experimental Study

Published on: 19th December, 2023

The primary objective of this study was to detect the success and short-term survival rate of dental implant prosthetic therapy. The valuation of a possible relationship between the general and local clinical conditions of the patients (presence of risk factors and type of dental implant-supported prosthesis) and the satisfaction perceived by the patient, with success and survival of implant devices was investigated.The sample trial consisted of 23 patients, for a total of 50 dental implants supporting a prosthetic therapy. Preliminarily, an analysis of averages and frequencies of the anamnestic data was presented, as numbers and percentages. The implant success rate was calculated by assessing whether the implants fulfilled the success criteria defined by the Pisa Consensus Conference. The ANOVA test was used to check whether there was an association between the success of the implant device, the anamnestic data collected, and the type of prosthesis supported by the implants. Finally, the survival rate was calculated using the Kaplan - Meier method.The 2-year success rate of 50 implants was assessed at 98%. The 2-year survival rate was 97%. Finally, sex, age, compensated diabetes, a smaller and equal number of cigarettes per day (10 per day), the BOP, and the type of titanium dental implants supported by prosthesis, do not determine a change in success and are therefore not adequate parameters to predict the outcome of implant success. Following the results obtained, it is appropriate to continue the research by expanding the clinical observation times in order to obtain more solid scientific and clinical evidence.

Update on the Clinical Applications of Mesenchymal Stem Cells

Published on: 21st December, 2023

Mesenchymal stem cells are heterogenous adult multipotent stromal cells that can be isolated from various sources including bone marrow, peripheral blood, umbilical cord blood, dental pulp, and adipose tissue. They have certain regenerative, anti-inflammatory, immunomodulatory, immunosuppressive, antimicrobial, and other properties that enable them to have several therapeutic and clinical applications including treatment of various autoimmune disorders; role in hematopoietic stem cell transplantation and regenerative medicine; treatment of skin, pulmonary and cardiovascular disorders; treatment of neurological and eye diseases; as well as treatment of various infections and their complications. Different factors including donor age, biological source, route of administration, and signaling pathways have an impact on the functions and consequently the clinical applications of mesenchymal stromal cells. The products of mesenchymal stem cells such as extracellular vesicles and exosomes reproduce the biological effects and most of the therapeutic actions of the parent stem cells. Genetic engineering and the use of specific mesenchymal stromal cell products have improved their clinical efficacy and decreased their adverse effects. However, despite the recent progress in the use of mesenchymal stem cells, the clinical application of these cells in the treatment of several diseases still faces real challenges that need to be resolved. The current status of mesenchymal stem cells and the controversies related to their clinical utilization in various disease conditions will be thoroughly discussed in this review.

Studies on the Influence of Charge Inducer and it’s Combination with P-gp Inhibitor to Improve the Oral Bioavailability of Nimodipine via Submicron Lipid Emulsions

Published on: 21st December, 2023

Background: Nimodipine (NM), is a dihydropyridine calcium channel blocker with poor oral bioavailability (BA) of about 13% due to first-pass metabolism and P-gp efflux. Objective: The present work aimed to study the influence of the charge inducer and its combination with P-gp inhibitor to improve the oral bioavailability of NM by developing a suitable delivery system of Submicron Lipid Emulsion (SME). Methods: Five SME formulations of NM were prepared by homogenization followed by ultrasonication. Prepared SMEs were characterized for particle size, PDI, Zeta Potential (ZP), Entrapment Efficiency (EE), and drug content. In vitro, release studies were performed in 0.1N HCl and pH 6.8 phosphate buffer by open tube method. The physical stability of all NM–SMEs was tested by the individual effects of centrifugation, dilution (desorption stress), and storage. Bioavailability studies were conducted on male Wistar rats after oral administration of NM suspension and F1 to F5 SME formulations. Results and conclusion: Five NM- SMEs were developed with a mean size ranging from 93 - 137 nm, Zeta potential of – 26 ± 1 mV (negatively charged), +45.8 to +46.3 mV (positively charged), and PDI of 0.15 - 0.25. The in vitro release studies showed that relatively more cumulative percentage release of NM – SMEs in 0.1N HCl than in pH phosphate buffer during 24 hours. The physical stability of NM–SMEs indicated that they were stable to the effects of centrifugation, dilution, and storage. Pharmacokinetic (PK) studies showed that the oral bioavailability of NM in F4 SME was significantly higher than that of all other formulations. Taken together, the results indicated the development of a stable lipid-based carrier, F4 SME to improve the oral bioavailability of this drug by minimizing first-pass metabolism due to lymphatic transport, reducing the efflux by P-gp inhibition, and further, by increased uptake of the positively charged F4 SME globules by enterocytes. Future: The research study findings increase the possibility of developing NM F4 SME by the pharmaceutical industry for the patient’s benefit.

Value of Speckle Tracking Echocardiography in Prediction of Left Ventricular Reverse Remodeling in Patients with Chronic total Occlusion Undergoing Percutaneous Coronary Interventions

Published on: 28th December, 2023

Background: Revascularization procedures for chronic complete occlusion (CTO) are technically challenging but aim to improve left ventricular (LV) function. The aim of this study is to evaluate the value of global longitudinal strain (GLS) measured by 2D-speckle tracking echocardiography( 2D-STE) in the assessment of LV reverse remodeling in patients with CTO undergoing revascularization by percutaneous coronary intervention (PCI).Methods: Our study included 54 patients with CTO treated by PCI. We evaluate LV systolic function by measurement of left ventricular ejection fraction (LVEF), left ventricular end-systolic volume (LVESV), and the GLS within 24 hours before the PCI and after 3 months post-procedure. Results: The mean age of the patients was 56.65 ± 7.65 years; 74.1% were males. There was a significant improvement in the LVESV (p < 0.001), LVEF (p < 0.001), and GLS (p < 0.001) at 3 months post-PCI, and by multivariate regression analysis, the GLS was the single most significant predictor of LV reverse remodeling post revascularization (p < 0.001).Conclusion: Revascularization of coronary CTO lesions by PCI is associated with a significant improvement in regional and global LV function. The GLS measured by 2D-STE is a strong predictor of LV reverse remodeling post-CTO interventions.

Mechanism of Action and Validation of the Traditional Medicinal use of Grewia Tenax Fruits in Sudan to Encounter Iron Deficiency Anemia

Published on: 27th December, 2023

Introduction: In Sudan, Grewia tenax fruits, are known commonly as Goddaim. The fruit’s pericarp is used traditionally for a long time as a juice or a porridge to treat iron deficiency anemia (IDA). Traditional Goddaim users have a very strong belief in its effectiveness. However, the pattern of hemoglobin improvement follows an initial fast increase followed by a decline upon continuing its use. Some previous studies have attributed its effect to high iron content, while the iron quantity was too small. This work attempts to find an explanation for its mechanism of action by screening the fruit extract and its respective fractions for secondary metabolites, minerals, vitamins, and fibre. Methods: Entailed three methodologies: Chemical analysis to identify quantified minerals, ascorbic acid and non-digestible fibers, Phytochemical Analysis to separate and identify secondary metabolites using high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS-MS technique), and estimation of radical scavenging activities of crude fruit extract and its respective chloroform and ethyl acetate fractions by inhibition of the 2,2-diphenylpicrylhydrazyl (DPPH).Results: Ascorbic acid and indigestible fibres were revealed in the aqueous extract. Secondary metabolites were flavonoids (e.g., quercetin, kaempferol), organic acids (e.g., ferulic acid, chlorogenic acid), β-carboline alkaloids (e.g., 3-hydroxy-tetrahydroharman) identified in the chloroform, and ethyl acetate fractions. The in vitro antioxidant activity of G. tenax fruit extract was confirmed spectrophotometrically. Conclusion: It can be concluded that the initial enhancement of iron absorption through ascorbic acid and fibres, followed by iron uptake inhibition, could be explained by iron chelation by the chelators in the fruits. This paradoxical effect may qualify G. tenax fruits as a safety gauge for improving haemoglobin levels without compromising iron excess once iron stores are filled by keeping the oxidative stress in check. This may present G. tenax fruits as a good and safe remedy that optimizes the treatment of IDA.
