Teacher Performance in the 21st Century: Examining the Roles of Leadership, Self-Efficacy, Compensation, and Job Satisfaction

The main purpose of this study is to examine the effect of leadership on teacher performance via self-efficacy and job satisfaction, a mediating variable, as well as compensation. Based upon an Indonesia study, the research engages a meta-analysis of these relationships for illuminating insights on optimizing teacher performance in educational environments. We collected data from a sample of 680 teachers 87% response rate and analyzed them using SmartPLS, the evaluation comparable to complex social science models. The results suggest that both self-efficacy and compensation affect teacher performance directly, respectively, through job satisfaction; principal leadership only has a significant direct effect on the dependent variable without being mediated by job satisfaction. These results may have implications for how intrinsic and extrinsic factors, motivation, rewards, and leadership styles influence faculty outcomes. The practical implications include a call for targeted teacher professional development and compensation policies that are more equitable and effective educational leadership practices to improve teaching performances, which will in turn favorably impact the quality of education generally.

Exploring the Impact of Employee Motivation on Investment Decisions: - A Study of Factors Influencing Mutual Fund Investment Among Corporate Employee

This study explores the impact of employee motivation on investment decisions, specifically focusing on the factors influencing mutual fund investments among corporate employees. As financial literacy and investment participation grow, understanding the underlying motivations that drive investment choices is crucial for both individuals and financial institutions. Utilizing a mixed-methods approach, we conducted surveys and in-depth interviews with corporate employees across various sectors. The findings reveal that intrinsic motivations, such as personal financial goals and career advancement, significantly influence mutual fund investment decisions. Additionally, extrinsic factors, including company-sponsored financial education programs and peer influence, play a critical role in shaping employees' investment behaviors. Our analysis indicates that motivated employees are more likely to engage in proactive financial planning and make informed investment choices. We also identified barriers such as risk aversion and lack of confidence in investment knowledge that hinder mutual fund participation. The implications of this study suggest that organizations should enhance employee motivation through targeted financial education initiatives and create a supportive investment culture. By doing so, companies can not only improve employee financial well-being but also foster a more engaged and motivated workforce. This research contributes to the existing literature on employee motivation and investment behavior, offering insights for corporate stakeholders and financial advisors aiming to enhance mutual fund investment strategies among employees.

The Influence of Extrinsic Motivation and Cross-Cultural Adjustment on Foreign Worker Commitment: The Mediating Role of Cross-Cultural Adjustment and Moderating Role of Employer Trust

Palm oil is a key income source in Malaysia, with the industry heavily reliant on foreign workers. This reliance necessitates a focus on their welfare to address workforce shortages. This study examines the relationship between extrinsic motivation and organizational commitment, mediated by cross-cultural adjustment and moderated by employer trust among foreign workers. This study employed a quantitative research design, using SPSS for data analysis, and surveyed 242 foreign workers from companies listed on the Malaysian Palm Oil Council (MPOC) website in 2022, achieving a 100% response rate. The key findings show that organizational commitment positively influences extrinsic motivation, with cross-cultural adjustment significantly enhancing both. Employer trust moderates the relationship between organizational commitment and cross-cultural adjustment, underscoring its importance in cultural adaptation and motivation. These insights highlight the need for targeted strategies to improve job satisfaction and retention among foreign workers by addressing extrinsic motivational factors and cultural adaptation challenges. The research contributes to the literature by detailing the interplay of organizational factors and cultural adaptation in shaping motivational outcomes, suggesting future research to explore longitudinal studies and other moderating variables. These findings offer valuable implications for improving workforce performance and retention strategies in the palm oil industry.

The Effect of Work Stress and Work Environment on Job Performance in Manufacturing Industry: A PLS-SEM Approach

Employee performance is a critical determinant of growth and success within manufacturing organizations, making it essential to understand the factors influencing it. This study delves into the effects of work stress and the work environment on job performance, specifically within the electronics manufacturing sector in Penang, Malaysia. The research addresses how role ambiguity and conflict can act as stressors and also explores how intrinsic and extrinsic motivation factors related to the work environment affect job performance. The study sample comprised 116 participants from five electronics manufacturing firms located in Bayan Lepas, Penang. Data collection was conducted through a structured questionnaire, and the analysis was performed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The results confirmed that the measurement model was robust, providing a solid foundation for validating the structural model. The PLS-SEM analysis demonstrated that the model had significant predictive capability, revealing that both work stress and the work environment exert substantial effects on job performance within the electronics manufacturing industry in Penang. Specifically, role stressors such as ambiguity and conflict were found to negatively impact job performance, while a supportive and motivating work environment positively influenced it. The study's results align with the theoretical frameworks of role stressors and self-determination, suggesting that effective management of stressors and the cultivation of a motivating work environment are essential for optimizing employee performance in the manufacturing sector.

Handling effects on dispersal of PIT‐tagged Flannelmouth Sucker

AbstractObjectiveHandling and tagging migrating fish might alter their behavior, limiting inference from mark–recapture studies. Posthandling flight of tributary spawning Flannelmouth Sucker Catostomus latipinnis was previously identified in Coal Creek in the upper Colorado River basin. Our objective was to determine if similar issues were present at McElmo Creek in the San Juan River basin.MethodsWe compared emigration timing of Flannelmouth Sucker that had been handled and tagged with passive integrated transponder tags during their tributary spawning run to individuals tagged in previous years and detected both entering and exiting the tributary. Linear mixed‐effects models were used to examine intrinsic and extrinsic factors contributing to exit timing.ResultSex and tagging year were associated with emigration timing, but handling did not result in posthandling flight from McElmo Creek. Females exited the tributary ~3 days before males, and larger fish emigrated earlier than smaller adults.ConclusionDifferences in capture technique and timing, available spawning habitat, and fish motivation across river systems may contribute to differences in posthandling emigration of tributary spawning Flannelmouth Sucker.

The Effect of Monetary Policies in COVID and Post-COVID on the Apple Stock Price and Beta

Abstract: Central bank interventions, such as monetary policies, influence market activities in many ways. For example, the stock price and beta value. Monetary policy is a mechanism to stabilize the market by adjusting the interest rate. Theoretically, the interest rate negatively relates to stock price and beta value. However, based on other previous research, the relationship can vary across industries and countries. Other determinants can also co-influence the stock activities, including business policies. Thus, each company experienced various results from the monetary policies during the COVID and post-COVID periods. Specifically, how did Apple Inc.s stock price and beta value react to the monetary policies released by FOMC? This paper explores Apple Inc. stock price and beta under the influence of monetary policies in the COVID and post-COVID period. Additionally, this paper finds that there is a significant negative relationship between the interest rates and stock price in COVID, and an insignificant negative relationship in post-COVID; There is an insignificant negative relationship between the interests rates and stock beta in COVID, and an insignificant positive relationship in post-COVID. Hence, stock price and beta are largely influenced by market dynamics and extrinsic factors. The contradictory result can be caused by the policies Apple Inc. released and the imprecise calculation.

House sparrows do not show a diel rhythm in double-strand DNA damage in erythrocytes.

DNA damage can be caused by a number of intrinsic and extrinsic factors. A recent study showed that free-living house sparrows (Passer domesticus) have higher DNA damage in the summer than the winter across five different tissues. This result was consistent when house sparrows were brought into captivity and exposed to comparable light cycles, with all other variables held constant. These results generated two hypotheses: (1) seasonal variation in DNA damage is related to circadian regulation and (2) seasonal variation in DNA damage is related to the total number of active hours. To investigate these hypotheses, we first quantified erythrocyte DNA damage in wild-caught house sparrows held in captivity on a 12L:12D light cycle at six points during the day to assess a diel or circadian rhythm but did not find one. We then performed a resonance experiment, in which birds experienced unnatural light cycles, and compared DNA damage in birds held on 6L:6D and 4.5L:7.5D resonance light cycles with their natural counterparts, 12L:12D and 9L:15D, respectively. We assessed corticosterone levels and DNA damage in blood before and after the resonance light cycles and DNA damage in abdominal fat, hippocampus, hypothalamus, and liver after the resonance light cycles. While our second experiment was not able to effectively test our hypotheses, we were able to demonstrate some interesting patterns. Throughout the resonance experiment, baseline corticosterone and testes size increased, consistent with the birds being photostimulated and preparing to breed. Surprisingly, the direction of change of DNA damage throughout the resonance photoperiod differed with tissue, which is not consistent with patterns during the breeding season in the wild. Our data indicate a potential uncoupling of the breeding physiology with the effect on DNA damage due to exposure to a resonance light cycle, which the birds may have interpreted as a skeleton photoperiod. Finally, though we were unable to fully disentangle the dynamics underlying seasonal DNA damage, we show that the previously documented patterns are not simply due to diel changes or the total amount of light exposure within a 24-hour period.

Physiographic determinants of suicide mortality in Pernambuco: an ecological study

Suicide is a serious and universal public health problem, reflecting a polysemic event with individual and collective repercussions. This study analysed aspects of suicide deaths in the state of Pernambuco, associating suicide indicators with physiographic factors. This is an ecological study, based on records of suicide deaths in Pernambuco from 1981 to 2020 from the Mortality Information System, using multiple linear regression to associate mortality indicators with extrinsic factors. The models constructed showed the influence of the proportion of trees, Gross Domestic Product and urbanisation. In this context, the most effective strategy for reducing the scale of suicide requires intersectoral interventions that impact on the population's quality of life and produce a healthier environment, taking on a character that goes beyond individual factors.

The Genomic Variation in Textured Hair: Implications in Developing a Holistic Hair Care Routine

Human hair is characterised by variability, determined by genetic and macromolecular factors. Whilst the European hair type has been a focus of extensive research, Afro-textured hair care faces challenges created by insufficient knowledge of its properties. Applications of hair care products that are incompatible with Afro-textured hair frequently have detrimental effects on the scalp. This highlights the need for partnerships to bridge the gap between research and hair care practices and address challenges related to Afro-textured hair. In this review, we performed data mining of the existing literature and in silico network analysis of the biomarkers relevant to Afro-textured hair. The approaches to hair maintenance are highlighted in the context of hair anatomy and growth cycles, organisation of keratins, surface lipids, and chemical bonds. We discuss a range of biomarkers affecting hair fibre’s shape and mechanical strength, with the gene interactive network pointing to the hierarchical organisation of important traits, notably hair shaft diameter, keratinization, and hair follicle patterning, which likely contribute to the increased sensitivity of hair to extrinsic factors. We propose that a better understanding of the genetic traits, molecular structure, and biomechanics of Afro-textured hair is required to initiate more effective hair care solutions that would benefit the wider population.

Escaping the midway trap: A mixed method study highlighting roadblocks and coping mechanisms of female researchers in Cameroon.

Across the world, women make most of the health workforce, but remain underrepresented in academia. This is even worst in Sub-Saharan Africa where women are the least represented as first and last authors in publications, especially in francophone countries. However, there is a lack of data on the reason explaining this inequity. Therefore, we sought to describe challenges which hinder the growth of Cameroonian female researchers and conducted a mixed method study over one year from January 2020 to December 2020. We included Cameroonian female researchers in health. For the quantitative arm, data was collected through an online google questionnaire. In-depth interviews were organized for the qualitative arm. Data was analyzed using python software version 21 for the quantitative arm and content analysis was performed for qualitative data. A total of 119 participants were included in this study. Most participants were aged between 25 and 35 years (72%) and they were Christians (94%). The majority had at least a PhD degree (29.6%) and they came from the West region of Cameroon (34.2%) the Northern regions were grossly underrepresented. More than half of our participants faced issues with balancing career, work, and academia and this is linked to culture. Socioeconomic, sociocultural, institutional, and environmental roadblocks hinder the progress and research productivity of most female researchers. The burden of unpaid maternity leaves, and sexual harassment remains high for most women. The use of English language as lingua Franca is perceived as another barrier for one on two women. However, there are coping strategies adopted by female scientists including the development of soft skills such as self-confidence, determination, and hard work. Extrinsic factors such as global policy, international partnerships, workshops, mentorship, and networking are also supporting women in global health. Gender-based interventions are critical to support women in escaping the midway trap.

Location and timing of infection drives a sex-bias in Haemoproteus prevalence in a hole-nesting bird.

Sex biases in prevalence of disease are often attributed to intrinsic factors, such as physiological differences while a proximate role of extrinsic factors such as behavioural or ecological differences may be more difficult to establish. We combined large-scale screening for the presence and lineage identity of avian malaria (haemosporidian) parasites, in 1234 collared flycatchers (Ficedula albicollis) with life-history information from each bird to establish the location and timing of infection. We found an overall infection rate of 36.2% ± 0.03 (95% CI) with 25 distinct malaria lineages. Interestingly, first-year breeding males and females had similar infection prevalence while females accrued a significantly higher infection rate than males later in life. The sex difference in infection rate was driven by the most abundant Haemoproteus, lineage, hPHSIB1, while the infection rate of Plasmodium lineages was similar in males and females. Furthermore, when infections were assigned to an apparent transmission location, we found that the sex difference in infection rate trend was driven by lineages transmitted in Europe, more specifically by one lineage (the hPHSIB1), while no similar pattern was found in African lineages. We deduce that the observed infection patterns are likely to be caused by differences in breeding behaviour, with incubating females (and nestling individuals of both sexes) being easy targets for the biting insects that are the vectors of avian malaria parasites. Overall, our results are most consistent with ecological factors rather than intrinsic factors underlying the observed sex-biased infection rate of avian malaria in collared flycatchers.

TRATAMENTO DE GORDURA INFRAORBITAL COM ULTRASSOM MICROFOCADO

Aging is a physiological process determined by various intrinsic and extrinsic factors, being a normal and inevitable process. The periorbital region is one of the first to show signs. This aging in the periorbital region is manifested by several anatomical changes that result in dark circles, wrinkles and sagging skin. These changes are influenced by factors such as the loss of adipose tissue volume and reduced collagen production, in addition to the projection of orbital fat and reduced skin elasticity. Given the significant aesthetic impact of these changes, effective treatment of dark circles has become a priority in aesthetic procedures. This study aimed to present and describe a treatment technique and its results in infraorbital pockets, using the non-invasive method of microfocused ultrasound. Through a case report involving a 50-year-old male patient with complaints of persistent dark circles, a treatment protocol was carried out with microfocused ultrasound using 60 shots per infraorbital region in two sessions, with an interval of 3 months. The evaluation of the results included photographic documentation and facial scanning, which showed a significant improvement in skin firmness and a reduction in infraorbital bags. The work concludes that microfocused ultrasound proved to be effective in treating localized fat and repositioning tissues in the dark circles region, promoting facial rejuvenation and representing a less invasive alternative to blepharoplasty. Results may vary depending on age, skin condition and technique used, in which case additional sessions may be necessary.

Mesenchymal stromal cells-derived small extracellular vesicles protect against UV-induced photoaging via regulating pregnancy zone protein.

Ultraviolet (UV) radiation is the primary extrinsic factor in skin aging, contributing to skin photoaging, actinic keratosis (AK), and even squamous cell carcinoma (SCC). Currently, the beneficial role of mesenchymal stromal cell-derived small extracellular vesicles (MSC-sEVs) in cutaneous wound healing has been widely reported, but the field of photoaging remains to be explored. Our results suggested that human umbilical cord MSC-derived sEVs (hucMSC-sEVs) intervention could effectively alleviate skin photoaging phenotypes in vivo and in vitro, including ameliorating UV-induced histopathological changes in the skin and inhibiting oxidative stress and collagen degradation in dermal fibroblasts (DFs). Mechanistically, pretreatment with hucMSC-sEVs reversed UVA-induced down-regulation of pregnancy zone protein (PZP) in DFs, and achieved photoprotection by inhibiting matrix metalloproteinase-1 (MMP-1) expression and reducing DNA damage. Clinically, a significant decrease in PZP in AK and SCC in situ samples was observed, while a rebound appeared in the invasive SCC samples. Collectively, our findings reveal the effective role of hucMSC-sEVs in regulating PZP to combat photoaging and provide new pre-clinical evidence for the potential development of hucMSC-sEVs as an effective skin photoprotective agent.

Repeated presentation of visual threats drives innate fear habituation and is modulated by environmental and physiological factors.

To survive predation, animals must be able to detect and appropriately respond to predator threats in their environment. Such defensive behaviors are thought to utilize hard-wired neural circuits for threat detection, sensorimotor integration, and execution of ethologically relevant behaviors. Despite being hard-wired, defensive behaviors (i.e. fear responses) are not fixed, but rather show remarkable flexibility, suggesting that extrinsic factors such as threat history, environmental contexts, and physiological state may alter innate defensive behavioral responses. The goal of the present study was to examine how extrinsic and intrinsic factors influence innate defensive behaviors in response to visual threats. In the absence of a protective shelter, our results indicate that mice showed robust freezing behavior following both looming (proximal) and sweeping (distal) threats, with increased behavioral vigor in response to looming stimuli, which represent a higher threat imminence. Repeated presentation of looming or sweeping stimuli at short inter-trial intervals resulted in robust habituation of freezing, which was accelerated at longer inter-trial intervals, regardless of contextual cues. Finally, physiological factors such as acute stress further disrupted innate freezing habituation, resulting in a delayed habituation phenotype, consistent with a heightened fear state. Together, our results indicate that extrinsic factors such as threat history, environmental familiarity, and physiological stressors have robust and diverse effects on defensive behaviors, highlighting the behavioral flexibility in how mice respond to predator threats.

Unraveling the developmental heterogeneity within the human retina to reconstruct the continuity of retinal ganglion cell maturation and stage-specific intrinsic and extrinsic factors.

Tissue development is a complex spatiotemporal process with multiple interdependent components. Anatomical, histological, sequencing, and evolutional strategies can be used to profile and explain tissue development from different perspectives. The introduction of scRNAseq methods and the computational tools allows to deconvolute developmental heterogeneity and draw a decomposed uniform map. In this manuscript, we decomposed the development of a human retina with a focus on the retinal ganglion cells (RGC). To increase the temporal resolution of retinal cell classes maturation state we assumed the working hypothesis that that maturation of retinal ganglion cells is a continuous, non-discrete process. We have assembled the scRNAseq atlas of human fetal retina from fetal week 8 to week 27 and applied the computational methods to unravel maturation heterogeneity into a uniform maturation track. We align RGC transcriptomes in pseudotime to map RGC developmental fate trajectories against the broader timeline of retinal development. Through this analysis, we identified the continuous maturation track of RGC and described the cell-intrinsic (DEGs, maturation gene profiles, regulons, transcriptional motifs) and -extrinsic profiles (neurotrophic receptors across maturation, cell-cell interactions) of different RGC maturation states. We described the genes involved in the retina and RGC maturation, including de novo RGC maturation drivers. We demonstrate the application of the human fetal retina atlas as a reference tool, allowing automated annotation and universal embedding of scRNAseq data. Altogether, our findings deepen the current knowledge of the retina and RGC maturation by bringing in the maturation dimension for the cell class vs. state analysis. We show how the pseudotime application contributes to developmental-oriented analyses, allowing to order the cells by their maturation state. This approach not only improves the downstream computational analysis but also provides a true maturation track transcriptomics profile.

Acquisition of durable insulin-producing cells from human adipose tissue-derived mesenchymal stem cells as a foundation for cell- based therapy of diabetes mellitus

This study aimed to identify the suitable induction protocol to produce highly qualified insulin producing cells (IPCs) from human adipose tissue derived stem cells (ADSCs) and evaluate the efficacy of the most functionally IPCs in management of diabetes mellitus (DM) in rats. The ADSCs were isolated and characterized according to the standard guidelines. ADSCs were further induced to be IPCs in vitro using three different protocols. The success of trans-differentiation was assessed in vitro through analysis of pancreatic endocrine genes expression, and insulin release in response to glucose stimulation. Then, the functionalization of the generated IPCs was evaluated in vivo. The in vitro findings revealed that the laminin-coated plates in combination with insulin-transferrin-selenium, B27, N2, and nicotinamide could efficiently up-regulate the expression of pancreatic endocrine genes. The in vivo study indicated effectual homing of the PKH-26-labelled IPCs in the pancreas of treated animals. Moreover, IPCs infusion in diabetic rats induced significant improvement in the metabolic parameters and prompted considerable up-regulation in the expression of the pancreatic related genes. The regenerative effect of infused IPCs was determined through histological examination of pancreatic tissue. Conclusively, the utilization of laminin–coated plates in concomitant with extrinsic factors promoting proliferation and differentiation of ADSCs could efficiently generate functional IPCs.

Harnessing Gene Editing Technology for Tumor Microenvironment Modulation: An Emerging Anticancer Strategy.

Cancer is a multifaceted disease influenced by both intrinsic cellular traits and extrinsic factors, with the tumor microenvironment (TME) being crucial for cancer progression. To satisfy their high proliferation and aggressiveness, cancer cells always plunder large amounts of nutrients and release various signals to their surroundings, forming a dynamic TME with special metabolic, immune, microbial and physical characteristics. Due to the neglect of interactions between tumor cells and the TME, traditional cancer therapies often struggle with challenges such as drug resistance, low efficacy, and recurrence. Importantly, the development of gene editing technologies, particularly the CRISPR-Cas system, offers promising new strategies for cancer treatment. Combined with nanomaterial strategies, CRISPR-Cas technology exhibits precision, affordability, and user-friendliness with reduced side effects, which holds great promise for profoundly altering the TME at the genetic level, potentially leading to lasting anticancer outcomes. This review will delve into how CRISPR-Cas can be leveraged to manipulate the TME, examining its potential as a transformative anticancer therapy.

Diversity of ancestral brainstem noradrenergic neurons across species and multiple biological factors.

The brainstem region, locus coeruleus (LC), has been remarkably conserved across vertebrates. Evolution has woven the LC into wide-ranging neural circuits that influence functions as broad as autonomic systems, the stress response, nociception, sleep, and high-level cognition among others. Given this conservation, there is a strong possibility that LC activity is inherently similar across species, and furthermore that age, sex, and brain state influence LC activity similarly across species. The degree to which LC activity is homogenous across these factors, however, has never been assessed due to the small sample size of individual studies. Here, we pool data from 20 laboratories (1,855 neurons) and show diversity across both intrinsic and extrinsic factors such as species, age, sex and brain state. We use a negative binomial regression model to compare activity from male monkeys, and rats and mice of both sexes that were recorded across brain states from brain slices ex vivo or under different anesthetics or during wakefulness in vivo . LC activity differed due to complex interactions of species, sex, and brain state. The LC became more active during aging, independent of sex. Finally, in contrast to the foundational principle that all species express two distinct LC firing modes ("tonic" or "phasic"), we discovered great diversity within spontaneous LC firing patterns. Different factors were associated with higher incidence of some firing modes. We conclude that the activity of the evolutionarily-ancient LC is not conserved. Inherent differences due to age and species-sex-brain state interactions have implications for understanding the role of LC in species-specific naturalistic behavior, as well as in psychiatric disorders, cardiovascular disease, immunology, and metabolic disorders.

Factors Influencing Job Satisfaction among Mental Health Nurses: A Systematic Review.

Job satisfaction is crucial for healthcare professionals, and understanding its influencing factors is essential for fostering a positive work environment, reducing turnover rates, and improving the overall quality of patient care. This systematic review examined the factors linked to nurse job satisfaction in psychiatric hospitals and diverse psychiatric settings, analyzing the findings through the lens of Herzberg's theory. Despite existing evidence, gaps remain in understanding the differences in factors affecting job satisfaction across various settings. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we conducted a comprehensive systematic review by searching six databases, namely PubMed, CINAHL, Cochrane Library, PsycINFO, Scopus, and APA PsycNet. Our search yielded an initial 567 studies published between January 2014 and February 2024, which were subsequently screened and evaluated based on predetermined inclusion criteria. Following this process, a total of 16 studies were deemed eligible for final analysis. Each of these selected studies underwent an independent review by two authors, utilizing the Joanna Briggs Institute checklist tool to ensure rigorous assessment. The findings revealed that interpersonal relationships, working conditions, and recognition were the most frequently reported factors associated with nurse job satisfaction, along with various extrinsic, intrinsic, personal, emotional, and psychosocial factors. Notably, psychiatric hospitals showed a mix of personal, extrinsic, intrinsic, and psychosocial factors influencing job satisfaction, with demographic factors being the most frequently examined. In contrast, diverse psychiatric settings focused more on external aspects impacting job satisfaction. The review highlights the importance of both intrinsic and extrinsic factors and suggests that future research should employ more robust methods and consider psychiatric hospitals and other mental health contexts. Herzberg's theory provides a valuable framework for understanding the factors associated with nurse job satisfaction.

The Respiratory Reflex of Cough: A Comparative Study of Contemporary Medicine and Unani Concepts

Cough suddenly and frequently helps to remove mucus, irritants, foreign substances, and bacteria from the airways. It can be a symptom of a respiratory infection like the common cold, bronchitis, tuberculosis, influenza, smoking, or other health issues. Contemporary texts describe several kinds of coughs, including acute, chronic, and subacute coughs, coughs that produce or do not produce mucus, and specific types like Reflex cough, voluntary cough, and evoked cough. In Unani texts, cough is referred to as diseases rather than symptoms. it is also called as “Sual” in Arabic, “Surfa” in Persian, khansi in Hindi, and cough in English. In Unani medicine, Sual is attributed to three causes: Ashab-e-badiya (extrinsic factor), Asbab-i- Wassila (intrinsic factor), and Iltehab (inflammation). The primary categories of Sual identified in Unani texts are Sual yabis and Sual Ratab, which are further subdivided into various types. This paper examines the concept, causes, types, and treatment approaches to Sual/Cough as described in both classical and modern literature. Keywords: Cough, Sual, Surfa, Modern concept Unani literature, sual yabis, sual ratab.
