Evaluation of the therapeutic potential and safety of Al Hayat black cumin seed oil: an observational study

The purpose of this study was to investigate the therapeutic potential and safety of the use of Al Hayat black cumin seed oil. Descriptive and discrete statistical methods and frequency analysis were applied. There were 20 participants in total aged between 11 and 67 years, both men and women. The participants were divided into three subgroups, each receiving different doses of black cumin oil: 10 mg/kg, 20 mg/kg, and 30 mg/kg, respectively. Such parameters as general blood count, liver enzyme activities (aspartate aminotransferase and alanine aminotransferase), creatinine, and serum iron levels were analysed. A dose of 10 mg/kg was found to have no significant therapeutic or adverse effect. A dosage of 20 mg/kg demonstrated positive effects on platelet, immune cell, and creatinine values with no significant side effects. A dose of 30 mg/kg is not recommended for use due to the high risk of adverse reactions. The author also found no significant differences in the therapeutic effects and adverse reactions to black cumin oil that could be related to the gender or age of the participants.

Investigating the visual content of a commercialized academic listening test: Implications for validity

As incorporating visual modes in listening tests is gradually gaining traction in second language (L2) assessment, the inclusion of such visuals brings up questions about the role of visual modes in meaning-making during listening and test validity. In this study, we investigated the visual features of the International English Language Testing System (IELTS) listening test through the application of the social semiotic multimodal framework. Our corpus comprised 300 visuals from 256 academic listening testlets published between 1996 and 2022. Unlike the past studies of social semiotic multimodal analyses that relied on qualitative methods, our study adopted a series of visualization and quantitative statistical analysis of frequency and dispersion measures, using the general linear model to examine the visuals from a social semiotic multimodal perspective. The results revealed significant variation in the visual structures of the testlets. Through applying a post-hoc analysis, we further proposed recommendations for further research on multimodal materials in listening assessment and discussed the implications of the observed variation for the validity of the IELTS listening test. This study may be considered one of the first attempts to examine L2 listening assessment from a social semiotic multimodal perspective that may inspire more investigations on multimodal listening.

Covert 19th century political intrigues of Tenerife nobility revealed by cryptanalyzing an encrypted letter

This article presents a cryptanalysis of a 19th-century encrypted manuscript discovered in the archives of Conde de Siete Fuentes in Tenerife, Canary Islands, Spain. The manuscript, preserved by the heirs of the 6th Count of Valle de Salazar, utilizes a polyalphabetic substitution cipher. The cryptanalysis was performed by applying statistical frequency analysis and developing a Python script for decryption, resulting in the authors successfully deciphering the message. The decrypted letter reveals political communications discussing the strategic positioning of Tenerife as the capital, the dissolution of local councils, and the influence of key political figures. The analysis compares the cipher with historical encryption techniques, and identifies the unique characteristics of the manuscript’s encryption method. The study highlights the political dynamics and alliances within Tenerife’s nobility and their interactions with the central Spanish government, providing significant insights into, both, the cryptographic practices and political maneuvers of the time.

Incidence of injuries and their prevention in Czech ice hockey players.

Ice hockey is a dynamic game. We can observe collisions between the players that bring a risk of injury. There are many hockey clubs in the Czech Republic. These clubs raise great hockey players and many competing players in various levels of national leagues. The aim of this study was to map injuries in Czech hockey players and outline the situation of injury prevention and body care in ice hockey players. We used a questionnaire survey method to obtain data. We received answers from 100 male active Czech ice hockey players, playing in the top three highest men's competitions (Extraleague - 2nd league). Individual injuries were analyzed according to specific body parts, injury type, playing position, level of competition using basic statistical characteristics and relative frequency analyses, including the recovery time, injury reason and the injury statistics per 1000 sporting performances in ice hockey. We found that 81% of participants suffered injuries with the overall incidence of injuries was 17.1 per 1000 sports performances and mainly happened during the match compared to training. The most common injuries were in the head and neck area (25%), often caused by a collision with another player, a stick or puck hit, or a collision with a board. Other frequently injured parts were the knees (21%), where internal ligament injuries predominate, and the shoulders (20%), where we recorded mainly ligament injuries. There is a high risk of various injury types of ice hockey players, that are developed accidentally in all body parts mostly in the match (mostly upper part of the body and knee) or by overloading (hip/groin area). We recommend strategies to avoid or minimize the injury risk of players. The hockey clubs, coaches, and players should extensively and regularly cooperate with physiotherapists, starting from the younger age of hockey groups, to prevent injuries and use regular strengthening of crucial muscle parts, regeneration, and compensatory exercises. We endorse adequately evaluating dangerous foul actions for referees and disciplinary officials also in minor competitions.

The amount of DNA and RNA in primary cancer cells and their metastases

Considering the significant impact of oncopathology on global morbidity and mortality, as well as changes in its prevalence and typology, research into the molecular-genetic mechanisms of oncogenesis and metastasis, particularly the role of nucleic acids, becomes crucial. The aim of this study is to determine the content of DNA and RNA in cells of primary cancer and its metastases through microspectrophotometric analysis of malignant cells collected from 30 patients with primary and metastatic oncological processes. The following methods were employed: microspectrophotometric analysis using the automated complex “Protva-PM11-DVK-3m,” staining of histological specimens with halo cyanin-chrome alum, the discrete statistics method, frequency and cluster analysis, and the bibliographic method. Changes in the concentration of nucleic acids in the cells of primary and metastatic tumors were identified during the study. The changes did not always correlate with each other, indicating morphofunctional polymorphism in tumor cell populations. A trend towards a decrease in nuclear RNA concentration and an increase in cytoplasmic RNA concentration in metastases were observed, suggesting alterations in metabolic and synthetic processes in cells and a decrease in their differentiation degree.

Human in vivo baseline intrarenal pressure, peristaltic activity and response to ureteric stenting.

To assess human in vivo intrarenal pressure (IRP) and peristaltic activity at baseline and after ureteric stent placement, using a narrow calibre pressure guidewire placed retrogradely in the renal pelvis. A prospective, multi-institutional study recruiting consenting patients undergoing ureteroscopy was designed with ethical approval. Prior to ureteroscopy, the urinary bladder was emptied and the COMET™ II pressure guidewire (Boston Scientific) was advanced retrogradely via the ureteric orifice to the renal pelvis. Baseline IRPs were recorded for 1-2 min. At procedure completion, following ureteric stent insertion, IRPs were recorded for another 1-2 min. Statistical analysis of mean baseline IRP, peristaltic waveforms and frequency of peristaltic contractions was performed, thereby analysing the influence of patient variables and ureteric stenting. A total of 100 patients were included. Baseline mean (±SD) IRP was 16.76 (6.4) mmHg in the renal pelvis, with maximum peristaltic IRP peaks reaching a mean (SD) of 25.75 (17.9) mmHg. Peristaltic activity generally occurred in a rhythmic, coordinated fashion, with a mean (SD) interval of 5.63 (3.08) s between peaks. On univariate analysis, higher baseline IRP was observed with male sex, preoperative hydronephrosis, and preoperative ureteric stenting. On linear regression, male sex was no longer statistically significant, whilst the latter two variables remained significant (P = 0.004; P < 0.001). The mean (SD) baseline IRP in the non-hydronephrotic, unstented cohort was 14.19 (4.39) mmHg. Age, α-blockers and calcium channel blockers did not significantly influence IRP, and no measured variables influenced peristaltic activity. Immediately after ureteric stent insertion, IRP decreased (mean [SD] 15.18 [5.28] vs 16.76 [6.4] mmHg, P = 0.004), whilst peristaltic activity was maintained. Human in vivo mean (SD) baseline IRP is 14.19 (4.39) mmHg in normal kidneys and increases with both hydronephrosis and preoperative ureteric stenting. Mean (SD) peristaltic peak IRP values of 25.75 (17.9) mmHg are reached in the renal pelvis every 3-7 s and maintained in the early post-stent period.

Rapid identification of living cancer cells based on label-free surface-enhanced Raman spectroscopy

Surface-enhanced Raman spectroscopy (SERS) is a highly sensitive vibration spectroscopy technique that can obtain fingerprint information of biomolecules in cells, and it has demonstrated significant potential in the early diagnosis of cancer. Here, we propose a rapid and efficient identification method of living cancer cells (within 10 min), which is based on the label-free SERS detection using iodide-modified Ag nanoparticles (Ag IMNPs) and the ultra-fast Raman mapping by line illumination. The Ag IMNPs achieve a better balance between sensitivity, reproducibility, and biocompatibility when compared to conventional Au or Ag nanoparticles. Statistical analysis of Raman peak frequency and intensity across substantial SERS spectra reveals a wealth of intracellular chemical information about the three cell lines 7701/7703/Caski. This method can not only accurately identify and classify normal cells, cancer cells, and various types of cancer cells, but it can also detect fingerprint changes in the distribution of intracellular chemicals. Furthermore, we discover that, among the three cell lines, liver cancer cells 7703 had the highest level of reactive oxygen species (ROS). This rapid SERS method can provide a new optical detection method for early screening, progression monitoring and prognosis assessment of tumors.

Risks and benefits associated with the primary functions of artificial intelligence powered autoinjectors.

This research aims to present and assess the Primary Functions of autoinjectors introduced in ISO 11608-1:2022. Investigate the risks in current autoinjector technology, identify and assess risks and benefits associated with Artificial Intelligence (AI) powered autoinjectors, and propose a framework for mitigating these risks. ISO 11608-1:2022 is a standard that specifies requirements and test methods for needle-based injection systems intended to deliver drugs, focusing on design and function to ensure patient safety and product effectiveness. 'KZH' is an FDA product code used to classify autoinjectors, for regulatory purposes, ensuring they meet defined safety and efficacy standards before being marketed. A comprehensive analysis of autoinjectors problems is conducted using data from the United States Food and Drug Administration (FDA) database. This database records medical device reporting events, including those related to autoinjectors, reported by various sources. The analysis focuses on events associated with the product code KZH, covering data from January 1, 2008, to September 30, 2023. This research employs statistical frequency analysis and incorporates pertinent the FDA, United Kingdom, European Commission regulations, and ISO standards. 500 medical device reporting events are assessed for autoinjectors under the KZH code. Ultimately, 188 of these events are confirmed to be associated with autoinjectors, all 500 medical devices were seen to lack AI capabilities. An analysis of these events for traditional mechanical autoinjectors revealed a predominant occurrence of malfunctions (72%) and injuries (26%) among event types. Device problems, such as breakage, defects, jams, and others, accounted for 45% of incidents, while 10% are attributed to patient problems, particularly missed and underdoses. Traditional autoinjectors are designed to assist patients in medication administration, underscoring the need for quality control, reliability, and design enhancements. AI autoinjectors, sharing this goal, bring additional cybersecurity and software risks, requiring a comprehensive risk management framework that includes standards, tools, training, and ongoing monitoring. The integration of AI promises to improve functionality, enable real-time monitoring, and facilitate remote clinical trials, timely interventions, and tailored medical treatments.

Ценностно-смысловые детерминанты профессиональной ответственности в обыденном представлении россиян

Background. The study of the value-meaning aspect of notions of professional responsibility is due to their potential impact on the efficiency of work and on psychological well-being of a specialist. The analysis of literary sources showed insufficient development of the emotional component of the studied phenomenon. Objectives. The article focuses on carrying out a structural and informative analysis of the views of Internet users on professional responsibility as well as on selecting value-meaning factors from the general context of representations. Study Participants. Users of the social network VKontakte and specialized Internet forums participated in the study. The number of author’s texts analysed was 1010. Each participant submitted one communication, i.e. the number of participants corresponds to the number of texts and amounts to 1,010 people. The total number of messages included 800 texts from the social network and 210 texts from the Internet forums. Methods. The study of ordinary representations of Internet users about professional responsibility is conducted with the help of statistical analysis of word occurrence frequency (PyMorphy2). Classification of the analyzed units (nouns, verbs, adjectives) is made on the basis of statistical processing and expert evaluation, structural elements of the phenomenon of “professional responsibility” and its value-meaning characteristics are shown. The analysis of contingency on the basis of testing with corpus of Russian language dataset RuTweetCorp, based on Bernoulli distribution, neuronetwork model of analysis of emotional background of messages (FastText), neuronetwork model Dostoevsky and dataset RuSentiment. Results. The conducted analysis allowed to present the structure of “professional responsibility”, to reveal cognitive, emotional, and behavioral components. The study identified a fourth meta-structural component, never previously identified by other authors, which is related to the “God” construct. The value-meaning patterns of professional responsibility have been identified and described. The analysis of the emotional background of the messages made it possible to highlight the trend towards negative assessments of the phenomenon of “professional responsibility” at the current stage of society development. Conclusions. The approach proposed in the study allows to reveal the psychological essence of professional responsibility, to highlight the importance of the emotional component in the strategies of acceptance/avoidance of responsibility. The equation of professional responsibility with personal responsibility of a specialist has been revealed, while the notions of national, social, and corporate responsibility are manifested insignificantly. The study of professional responsibility through the value-meaning aspect can become the basis for analysis of social behavior in a person as a whole in the future.

Science mapping provided key findings about the main thematic research field&#x2019; clusters and their evolution overtime: technology application in agricultural industry, data model for analysis and prediction, experimentation and applicative studies of smart agriculture, decision support systems for crop monitoring. This study could benefit: food companies, supporting in technologies identification; governments, suggesting policies to stimulate agricultural digitalization process; academics, incentivizing more consciousness about the topic and research agenda; those who approach this topic for the first time, facilitating bibliographical referencing.

Home Care Nursing: Factors Related to Burden of Patient Encounters Perceived by Home Care Nurses

Due to demographic changes and structural developments in the healthcare system, an increasing number of patients receive home care nursing in Denmark. Little is known about the complexity of home care. The aim of this paper was to investigate the challenges that home care nurses experience in their clinical practice by studying factors related to home care nurses’ experiences of encounters with patients as burdensome. A population-based survey was undertaken involving all nurses in homecare services in one municipality in Denmark. The participating nurses registered all home care contacts by the patients during the daytime for 1 week. A registration form was used including a series of items designed to identify factors related to the perceived burden of each visit. Statistical frequency analyses were used to examine factors related to the home care nurses’ experiences of encounters with patients as burdensome, and to investigate the challenges that home care nurses meet in their clinical practice. Home care nurses estimated 7.6% of 941 representative homecare visits as burdensome. Assessment of burden was associated with patients being below 60 years of age, time consumption and unexpected problems during the visit, especially of a psychosocial nature. Even though &lt;10% of the encounters were considered burdensome, there is reason to believe that an increase can be expected due to ongoing emphasis on achieving greater efficiency in the healthcare system.

Landslide Occurrences under Diverse Landuse/cover in Lower Kosi Watershed, Central Himalaya

Abstract Present study was related to land degradation after landslide and risk analysis of Lower Kosi watershed in Central Himalaya using RS and GIS. The study was aimed to identifying the relation of land use with landslide activity in Himalayan terrain and landslide management. The landslide inventory map was prepared for the detailed study with the help of Google Earth Image and field verifications. Landslide had been sub-categorized into two categories; natural and road induced. The land use map was prepared from Google Earth image followed by toposheets. Statistical analysis of landslide frequency and density as well as frequency and density ratios were applied. The collected data was evaluated in combination with GIS. The relationship between land use categories and landslide occurrences was determined. The landslide frequency ratio (FR) and density ratio (DR) were analyzed. The FR and DR value of 1 is an average value. Hence, the value of ratio more than 1 signifies a strong relationship between landslides and the given factor while ratio values less than 1 registers a poor relationship. The FR and DR values were &amp;gt;1.0 in the areas of fallow land, barren/rocky land, agricultural land and open forest revealing a strong relation to landslide processes while the lesser values of FR and DR in ‘dense forest’ area determines the impact of sufficient vegetation cover on the least occurrence of landslides. This study may be applicable for new and existing land use planning projects as the adopted methodology provides rapid estimation of landslide vulnerability of the area.

Drug Dependency Due to Traumatic Childhood Experiences and Low Emotional Intelligence of Juvenile Felons in India

ABSTRACT Children involved with the juvenile justice system for engaging in unlawful acts are more likely than their peers of the same age to use cannabis and alcohol, which increases the likelihood of adverse behavioral outcomes and prolonged involvement with the judicial system. This study focuses on the relationship between child maltreatment, emotional intelligence and drug dependence among children in conflict with the law. The participants of the study are 130 justice-involved male juveniles in the Indian state of Tamil Nadu who are given the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST), the Juvenile Victimization Questionnaire (JVQ), and Emotional Intelligence Scale (EIS) for assessment. Interviews are conducted to obtain the data required for the study. For the statistical analysis, frequency, t-test, correlation, and regression analyses are used. Results of the study indicates that low level/lack of emotional intelligence which enhances the likelihood of juveniles being in conflict with the law and engaging in harmful, drug-dependent behavior. No significant relationship is observed between child maltreatment and drug-dependent behavior. For these juveniles, marijuana serves as the gateway drug. Peer influence and school dropout have a substantial influence on drug-dependent behavior.
