Prevalence of hypovitaminosis D is not restricted to the elderly and hospitalized population. Worldwide, the rate of prevalence of vitamin D deficiency has grown up rapidly in adults over the past decades. Among Libyan population including young students may has a high risk of vitamin D deficiency. The aims of this study were to examine vitamin D status among pharmacy students of Sebha University and to study the hematological profile as well as correlation of vitamin D deficiency with incidence of anemia among the students. This study was carried out on Pharmacy students from 13th January to 12th March, 2020. This is a cross-sectional study designed to determine vitamin D status among healthy young pharmacy students studying at the Sebha University. The blood samples were collected randomly from 62 pharmacy students to analysis complete blood count and 25-hydroxyvitamin D. The concentration of hemoglobin on total student was 12.5 ± 1.9 g/dl which was normal according to the WHO level (12.0 g/dl). Out of total, 36 students (59.1%) were found to have normal hemoglobin concentration (13.7 ± 1.4 g/dl) and 26 students (40.9 %) were found to have low hemoglobin concentration (10.8 ± 1.1 g/dl). Other blood profile as HCT, MCV, MHC and MCHC where statistically significant lower but the counts of RBCs, WBC and platelets were not on anemic group comparing to normal group. The present study reported that majority of pharmacy students in male and female blood donors have low vitamin D levels which represent (87.0%). Out of the total participants (n = 54) who have low vitamin D (n = 49, 79.0%) were classified under vitamin D deficiency category while (n = 05, 08.0%) of students had vitamin D insufficiency. In conclusion, prevalence of hypovitaminosis D (low 25-hydroxyvitamin D) among the pharmacy students at Sebha University was highly occurrence with concomitant a high rate of prevalence of anemia. Thus, vitamin D deficiency at this age represents a public health problem that should be addressed.

n India, the education sector has been always attentive to adopt innovations and techniques in the teaching-learning process due to various challenges. But nowadays, academic institutions are becoming flexible in accepting the new teaching and learning techniques to satisfy the student sector which as cited as the most vital entity in the educational sector. New technologies, tools, and techniques are proving as a boom for innovative teaching and learning practices. One of the emerging teaching technique is Blended learning which is a process refers to “mixing of the different learning environment for educational transfer”. It combines the traditional face to face classroom method with online learning method supported by advanced technology and tools. Blended learning should be viewed not only as a temporal construct but also as a fundamental redesign model. Through this content, delivery becomes digital and online. Truly blended learning requires teachers should adopt the approach as guides and mentors and learning should go beyond the classroom walls. Blended learning is also known as Hybrid learning. Although, Indian Government is taking initiatives to implement a blending learning approach yet there is a need to access the behavioral aspect of the students to use this blending learning approach. Adopting a blended learning approach must start with a re-examination of the intended learning outcomes.The deployment of cloud in the blended learning process makes its existence more strong. This study is the review of literature selected to identify the need for blended learning deploy with cloud in the teaching-learning process in the Higher Education Sector.

Background Osteoarthritis (OA) is a significant global health concern and is characterized by the degeneration of joint structures, leading to pain, stiffness, and functional limitations It is estimated that 654.1 million individuals are affected by osteoarthritis worldwide, with females, especially those older than 60 years of age, being the population most impacted. However, there remains a gap in understanding the awareness of knee osteoarthritis among specific populations, such as the Palestinian community in the West Bank, thus, highlighting the need for targeted research to address this health disparity. Methods A cross-sectional survey was conducted in the West Bank from August to September 2024. Participants were recruited from 11 cities and a validated questionnaire adapted from a previous study was used to collect the data. The reliability of the questionnaire was assessed using Cronbach’s alpha, yielding a value of standard alpha = 0.71, which is an acceptable value. The survey collected demographic data, clinical characteristics, knowledge of osteoarthritis risk factors, symptoms, and attitudes towards treatment options. R Statistical Software was used for data analysis, which included descriptive statistics, chi-square tests, and logistic regression to explore the relationships between demographic factors and osteoarthritis knowledge, whereby a p-value of ≤ 0.05 was set up as a significance level. Results A total of 725 valid responses were included in our study. Among the participants, 569 were female, predominantly aged 25 or younger (66%, n = 479), and 62% (n = 450) were single. Knowledge assessment revealed that 80% (n = 580) recognized knee osteoarthritis as a chronic disease, while only 51% (n = 369) understood its impact on joint involvement. The majority identified high BMI (87%, n = 632), advancing age (94%, n = 683), and previous knee injury (72%, n = 520) as risk factors, although only 42% (n = 306) acknowledged genetics as one. Most participants were aware of the management strategies, including analgesics (70%, n = 510) and physiotherapy (80%, n = 579). However, 66% (n = 478) scored low for overall knowledge regarding knee osteoarthritis. Conclusion This study emphasizes the critical importance of raising awareness and knowledge about osteoarthritis within the Palestinian community. Despite being widely known as a long-term issue, there are still noticeable gaps in the understanding of the joint impact, potential risks, and effective treatment methods for osteoarthritis. The use of informal sources highlights the importance of specific educational programs by healthcare providers.

Air pollution is a major health problem in developing countries and has adverse effects on human health and the environment. Non-thermal plasma is an effective air pollution treatment technology. In this research, the performance of a dielectric barrier discharge (DBD) plasma reactor packed with glass and ceramic pellets was evaluated in the removal of SO2 as a major air pollutant from air in ambient temperature. The response surface methodology was used to evaluate the effect of three key parameters (concentration of gas, gas flow rate, and voltage) as well as their simultaneous effects and interactions on the SO2 removal process. Reduced cubic models were derived to predict the SO2 removal efficiency (RE) and energy yield (EY). Analysis of variance results showed that the packed-bed reactors (PBRs) studied were more energy efficient and had a high SO2 RE which was at least four times more than that of the non-packed reactor. Moreover, the results showed that the performance of ceramic pellets was better than that of glass pellets in PBRs. This may be due to the porous surface of ceramic pellets which allows the formation of microdischarges in the fine cavities of a porous surface when placed in a plasma discharge zone. The maximum SO2 RE and EY were obtained at 94% and 0.81 g kWh−1, respectively under the optimal conditions of a concentration of gas of 750 ppm, a gas flow rate of 2 l min−1, and a voltage of 18 kV, which were achieved by the DBD plasma packed with ceramic pellets. Finally, the results of the model's predictions and the experiments showed good agreement.

In the United States, prisoner reentry programs are a necessity to re-integrate back into society and are of two types: Faith and Non-Faith. With increased emphasis placed on reforming the criminal justice system policies due to Black Lives Matter and other non-profits actively working to change the system from the outside, reentry programs are having a resurgence of interest for effective public policy. There are significant barriers for major policies at the state, local, and federal to be alleviated, nevertheless, our research wanted to consider the effectiveness of five faith-based, male-only reentry programs in central Florida. Small focus groups were utilized to better understand the concerns and issues returning inmates faced in the program as well as when returning to society. Reentry participants were found to have high confidence in the success of their participation in their faith-based program’s efforts on their personal and family growth.

Garcinia cambogia, commonly known as Asam Gelugur, has entrenched itself as a traditional herbal medicine, renowned for its applications in treating obesity and its integration into global nutraceutical formulations. The bioactive compounds within, particularly hydroxy citric acid, mediate various effects. This study aims to assess the in vitro cytotoxicity of Taxol, a cytotoxic drug used as a control, and the aqueous extract from Garcinia cambogia against the Vero cell line - a kidney-like cell. Cytotoxicity was evaluated using the 3-(4,5-dimetyl-2-2thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide (MTT) assay. The assay relies on mitochondrial succinate dehydrogenase's potential to reduce MTT, providing a colorimetric indication of cell viability. The results revealed an IC50 value exceeding 500 µg/mL for the aqueous extract from Garcinia cambogia significantly higher than Taxol's 0.0581 µg/mL. This higher IC50 value implies lower toxicity, positioning the Garcinia cambogia extract as a safe component in nutraceuticals and herbal supplements. The aqueous extract of Garcinia cambogia demonstrates low cytotoxicity, reinforcing its safety profile for use in nutraceuticals, which contributes valuable insights into the safety considerations of incorporating Garcinia cambogia into herbal supplements.

The main aim of rehabilitation is vocational independence and community integration. Rehabilitation is complete with the person being a productive member within the community. But this is quite a challenging task as can be vouched by any of the professionals working in this field. What are the barriers and facilitators towards employment or return to work in case of persons living with mental illness? Literature shows that multiple factors are governing the ability to take up gainful employment. Most of this literature is about the western world where the social fabric is more supportive of individual autonomy. India lags in its rehabilitation efforts for mental illness. There is still stigma and lack of awareness about mental illnesses. This increases the problem of unemployment within persons living with mental illness manifold. There are very few detailed investigations into the vocational status of persons with mental illness and almost negligent literature existing in the Indian context. Hence, the current review article tries to examine the factors prevailing in the Indian scenario that influences the employment status.

Simply put, advertising is an important marketing strategy that works in conjunction with information and persuasion channels. Every single person is exposed to commercials on a daily basis. They've become an inseparable part of the print medium, whether it's newspapers or magazines, over time. This is also true in the case of broadcast media, where ad-commercials predominate. The Indian advertising industry has grown tremendously from a small business to a full-fledged industry. The purpose of this study is to determine the advertising attractions and the influence they have on Indian culture. Advertisements in India are not only used to sell products. It sells dreams, visions, and the ideal way of life, while also reinforcing stereotyped values. The longer an individual is exposed to an advertisement, the more likely it is that it will effect them. The appeals' goal is to change how people think about themselves and how they decide whether or not to buy certain things will benefit them. Because India has such a large population and cultural diversity, the advertising industry has created a wide range of advertisements to capture people's attention and persuade them to buy products. The appeals are written in such a way that they have an impact on people's purchasing decisions.

Patients’ knowledge of hypertension and treatment has been found to affect health outcomes of hypertension. This study aimed to assess the impact of therapeutic patients’ education on knowledge of hypertension and lifestyle/dietary modification among hypertensive patients in Nigeria. The study was conducted among 317 hypertensive patients randomized into controlled and intervention groups (158 vs 159, respectively) between March 2021 and February 2022. Baseline knowledge of the patients was assessed and intervention was provided for the intervention group with a structured educational program at a baseline and six months. Descriptive data were presented with a frequency table in percentage while the chi-square test and univariate logistic regression were used to determine the association between categorical variables. Out of the total number of 318 patients, 275 completed the study (response rate: 86.8%) with 136 in the control group and 139 in the intervention group. The mean age of the patients was 59.5 (±12.5) and patients > 60 years (49.5%) were the most frequent age category. The baseline knowledge score of hypertension was 9.8 (±2.6) and 9.3 (±2.6) on a scale of 16 points in the control group and intervention group, respectively (P = 0.060) while at six months 11.9 (±2.3) vs 10.8 (±2.4) (P < 0.001) and 12 months 12.6 (±2.5) vs 9.5 (±2.0) (P < 0.001), respectively. Knowledge of lifestyle/dietary modification in the control group and intervention group at baseline was 7.0 (±2.1) and 6.6 (±2.0), respectively, while at six months 7.5 (±1.5) vs 9.9 (±1.3) (P < 0.001) and at 12 months 7.2 (±1.5) vs 10.4 (±1.2), respectively. Marital status, body mass index, and family history of hypertension were associated with knowledge of hypertension and lifestyle/dietary modification (P < 0.001). The educational intervention provided was found to be associated with a significant improvement in knowledge of hypertension and lifestyle/dietary modification. The marital status of the patients, body mass index and family history of hypertension influenced patients’ level of knowledge.

Metamizole or Novalgin® is a widely used well tolerated analgesic drug which is however compromised by agranulocytosis as adverse effect. Subsequent to nonenzymatic hydrolysis, the primary metabolic step is N-demethylation of 4-methylaminoantipyrine (4-MAA) to 4-aminoantipyrine (4-AA). The aim of the present study was to identify the human cytochrome P-450 enzyme (CYP) mediating this reaction. This study identified the relevant CYP using virus expressed isolated human CYP, human liver microsomes and rat liver microsomes with chemical inhibition studies. The substrate of 4-methylaminantipyrine was employed at six different concentrations (25, 50, 100, 400, 800 and 1200 µmol per l) with varying concentrations of selective inhibitors of CYP1A2 (furafylline, fluvoxamine), CYP3A4 (ketoconazole), CYP2A6 (coumarin), CYP2D6 (quinidine), CYP2C19 (omeprazole, fluvoxamine, tranylcypromine), CYP2C9 (sulphaphenazole) and CYP1A1 (alpha-naphthoflavone). 4-MAA and 4-AA were analyzed by HPLC and enzyme kinetic parameters (Km and Vmax) were determined by regression (Sigma plot 9.0). The N-demethylation of 4-MAA by microsomes prepared from baculovirus expressing human CYP was pronounced with CYP2C19. Intrinsic clearance of the most active enzymes were 0.092, 0.027 and 0.026 for the CYP enzymes 2C19, 2D6 and 1A2, respectively. Metabolism by human liver microsomes was strongly inhibited by fluvoxamin, omeprazole and tranylcypromine (IC50 of 0.07, 0.07 and 0.18, respectively) but with coumarin, sulphaphenazole, ketoconazole, moclobemid, quinidine alpha-naphthoflavone and furafylline were 0.79, 1.20, 1.36, 1.44, 3.46, 4.68 and 8.41, respectively. The enzyme CYP2C19 apparently has an important role in N-demethylation of 4-methylaminoantipyrine which should be further analyzed in clinical studies and which may also be interesting concerning the agranulocytosis.

The seeds for this work were planted many years ago when Linda Bean wastranscribing some of my lectures and encouraged me to write a book. Shepatiently labored through years of archived material until it was time for me tobegin writing. Her commitment and dedication to this project are deeplyappreciated.Once I began writing, Karen Entner assisted me by organizing materials,making content suggestions, and maintaining the manuscript. We workedtogether to edit version after version until the flow of words brought a sense ofpeace to the heart, mind, and soul. Her dedication and heartfelt work are muchappreciated and one of her lifelong dreams comes to fruition with the publicationof this book. “This above all: to thine own self be true, and it must follow,as the night the day, thou canst not then be false to any man.” —William ShakespeareShakespeare’s age-honored words, spoken by Polonius to his son Laertes in ActI of Hamlet, sound so clear and unambiguous. They tell us that to maintainhonest relations with others we must first be true to ourselves. Yet if Laerteswere to be totally honest with himself, he would realize that his father may aswell have told him to catch the wind. After all, to which “self” are we to be true?Is it the one that shows up when we’re in a bad mood, or the one that is presentwhen we feel humbled by our mistakes? Is it the one who speaks from the darkrecesses of the heart when we’re depressed or upset, or the one that appearsduring those fleeting moments when life seems so fanciful and light?From these questions we see that the concept of “self” may turn out to be abit more elusive than initially presumed. Perhaps if Laertes could have turned totraditional psychology, it would have shed some light on the subject. Freud(1927), the father of psychology, divided the psyche into three parts: the id, theego, and the superego. He saw the id as our primal, animal nature; the superegoas the judgment system that society has instilled within us; and the ego as ourrepresentative to the outside world that struggles to maintain a balance betweenthe other two powerful forces. But this certainly would not have helped youngLaertes. After all, to which of these conflicting forces are we to be true?Again we see that things are not always as simple as they seem. If we dare tolook past the surface of the term “self,” questions arise that many people wouldrather not ask: “Are the many aspects of my being all equally part of my ‘self,’or is there only one of me—and if so, which, where, how, and why?”In the following chapters, we will undertake a journey of exploration of“self.” But we will not do so in a traditional manner. We will neither call uponthe experts in psychology, nor upon the great philosophers. We will not argueand choose between time-honored religious views, or resort to statisticallysupported surveys of people’s opinions. We will, instead, turn to a single sourcethat has phenomenal direct knowledge on the subject. We will turn to one expertwho, for every moment of every day of their life, has been collecting the datanecessary to finally put this great inquiry to rest. And that expert is you.

Since the WHO declared COVID-19 a pandemic on March 11, 2020, all countries worldwide have taken precautions to combat this pandemic, except for Yemen. The civil war and resulting humanitarian crises have diverted the attention of the Yemeni people and authorities away from COVID-19, potentially leading to the escalation of the pandemic. Following the initial denial, the internationally recognized government and the de facto authority of the Houthis acknowledged the first COVID-19 cases on March 11, 2020 and May 13, 2020, respectively. With only half of the Yemeni hospitals and medical facilities being fully operational, the authorities and humanitarian groups are working together to end the crisis. Due to paucity of information on the real number of cases in the country attributed to various reasons, no one can predict the future in this country, which will be most likely worse unless the civil war stops, and the humanitarian groups with the authorities need to work hard to strengthen the health system to prepare it for the current and all upcoming health crisis and pandemics.

Background and Aim: Ultrasound popliteal sciatic nerve block (UPSNB) is commonly performed in foot and ankle surgery. This study aims to assess the use of dexmedetomidine and dexamethasone as adjuvants in UPSNB for hallux valgus (HV) surgery, comparing their efficacy in producing motor and sensory block and controlling postoperative pain. The adverse event rate was also evaluated. Methods: This mono-centric retrospective study included 62 adult patients undergoing HV surgery: 30 patients received lidocaine 2% 200 mg, ropivacaine 0.5% 50 mg and dexamethasone 4 mg (Group 1), whereas 32 patients received lidocaine 2% 200 mg, ropivacaine 0.5% 50 mg, and dexmedetomidine 1 mcg/Kg (Group 2). At first, the visual analogue scale (VAS) was evaluated after 48 hours. The other outcomes were time to motor block regression, evaluation of the first analgesic drug intake, analgesic effect, adverse effects (hemodynamic disorders, postoperative nausea and vomiting (PONV)) and patient satisfaction. The continuous data were analyzed with student’s t-test and the continuous one with χ2. Statistical significance was set at a p-value lower than 0.05. Results: No significant difference was found in VAS after 48 hours (4.5 ± 1.6 vs 4.7 ± 1.7, p = 0.621) to motor block regression (18.9 ± 6.0 vs 18.7 ± 6, p = 0.922). The number of patients that took their first analgesic drug in the first 48 h (p = 0.947 at 6 hours; p = 0.421 at 12 hours; p = 0.122 at 24 hours and p = 0.333 at 48 hours) were not significant. A low and similar incidence of intraoperative hemodynamic disorders was recorded in both groups (hypotension p = 0.593; bradycardia p = 0.881). Neither PONV nor other complication was found. Patients in Group 1 reported a lower degree of interference with sleep (p = 0.001), less interference with daily activities (P = 0.002) and with the affective sphere (P = 0.015) along with a more satisfactory postoperative pain management (p < 0.001) as compared to Group 2. Conclusion: No significant differences were observed in the duration of motor and sensory blockade between patients in both groups. Additionally, both groups showed good pain control with a low rate of adverse effects, even if there was no clinical difference between the groups. However, patients who received dexamethasone reported experiencing less interference with their sleep, daily activities and overall emotional well-being, and overall pain control.

Background: Exhaust noise is known to be a major pollutant in the environment and workplaces due to the development of industry and transportation. Exhaust noise can be reduced to normal levels by mufflers or silencers. A reactive muffler efficiently dampens noise at low frequencies by reflecting sound waves. Therefore, muffler design is of great importance in exhaust noise reduction. Transmission loss (TL) is an essential characteristic of mufflers, demonstrating their acoustical properties. Any acoustical appliance is selected based on its damping performance and reliability. Predicting TL through experimentation is different from theoretical calculations. Methods: In the present study, a double-expansion chamber muffler was designed as a reflective muffler on a laboratory scale by equations. Next, TL was evaluated by an impedance tube applying a 4-microphone technique to determine the acoustical performance of the designed muffler. Results: Findings revealed that the TL of the muffler at 312 Hz frequency obtained 27.5 dB agreement with the required TL of the muffler of 25 dB. In addition, the TL of the muffler against frequency attenuates noise in broadband frequencies. Conclusions: These results indicated that the built muffler provides desired TL for exhaust chambers. Therefore, equations can be used as a precise method for muffler design. Furthermore, multi-expansion chamber mufflers are useful for reducing noise at a wide range of frequencies.

Background: The first wave of the COVID-19 pandemic was associated with significant morbidity and mortality among healthcare workers worldwide. The present study aimed to assess the knowledge, attitudes, and practices of healthcare workers toward COVID-19 at Ataq General Hospital, and three other hospitals and health centers in Shabwah Governorate, Yemen. Materials and Methods: From January 1, 2022, to February 28, 2022, a cross-sectional survey of healthcare workers was conducted in the city of Ataq, Shabwah Governorate at the following hospitals: Ataq General Hospital, Al Shefa’a Hospital, Al Aafiah Hospital, and COVID-19 Isolation Center. Results: A total of 107 healthcare workers completed the survey. Their mean age was 28.17 ± 7.73 years, 79 (73.8%) of them were male and 28 (26.2%) were female. The overall knowledge was good, with a score of 19 out of 21; however, most participants were unaware of some of the extra-respiratory symptoms of the disease, such as diarrhea and confusion, and about 57% of them were unaware that eating or interacting with wild animals may contribute to the infection with the COVID-19 virus. Attitude analysis of the participants revealed that about half of those surveyed do not believe that Yemen can contain COVID-19. In general, the practice of the participants was good. Conclusion: Although the overall knowledge score in this study was good, most respondents could not recognize some of the extrapulmonary manifestations of COVID-19 and were unaware of the possibility of transmission of the disease from wild animals. In addition, about half of those surveyed do not believe that Yemen can contain COVID-19
