Geotextile can be worth their cost in pavement

Geotextiles have been successfully used for reinforcement of soils to improve the bearing capacity. In this study geotextile as a tensional material have been used for reinforcement of granular soils. Laboratory California Bearing Ratio (CBR) tests were performed to investigate the load-penetration behavior of reinforced soils with geotextile. Samples of granular soil are selected and tested without reinforcement. Then CBR tests were performed by placing geotextile in one or two layers at various depths in soil sample. The effect of the number of geotextile on the increase in bearing capacity of reinforced granular soil is discussed.

The effects of severe hypobaric hypoxia and inhibition of hypoxia-inducible factor-1 (hif-1) on biomarkers of cardiac and skeletal muscle injury in rats

The goal of the present study was to investigate the molecular mechanisms that underlie heart andskeletal muscle damage in male Wistar rats weighing 200–250 g in response to a 3-h exposure to 180 mm Hg(5% O2) in the model of severe hypobaric hypoxia. It has been demonstrated that the level of the cardiac bio-marker troponin I in the blood plasma of rats exposed to severe hypobaric hypoxia for 3 h increased signifi-cantly compared to the control group, indicating myocardial injury. At the same time, the administration ofthe HIF-1α transcription factor inhibitor did not affect the plasma level of troponin I. In contrast, the releaseof the non-specific biomarker myoglobin into the bloodstream did not increase in response to hypoxia com-pared to the control animals. In addition, 24 h after the exposure to severe hypobaric hypoxia the serum myo-globin level was significantly lower in animals administered with the HIF-1α inhibitor topotecan than in ratsthat did not receive topotecan. Therefore, it may be assumed that the inhibition of the HIF-1α transcriptionfactor 10 min before exposure to severe hypobaric hypoxia reduces skeletal muscle damage. The mechanismsthat affect the adaptation of heart and skeletal muscles to hypoxia are discussed.

Online interviews for qualitative health research in africa: a scoping review

Online interviews can be powerful tools in global health research. In this article, we review the literature on the use of and challenges associated with online interviews in health research in Africa and make recommendations for future online qualitative studies. The scoping review methodology was used. We searched on Medline and Embase in March 2022 for qualitative articles that used internet-based interviews as a data collection method. Following full-text reviews, we included nine articles. We found that online interviews were typically conducted via Microsoft Teams, Zoom, Skype, WhatsApp, Facebook Messaging and E-mail chats. Online interviews were used in Africa because of the restrictions imposed by the coronavirus disease 2019 pandemic and the need to sample participants across multiple countries or communities. Recruitment for online interviews occurred online, interviews were characterised by inaudible sounds, the inability to use video options and the challenges of including people with low income and education. We recommend that researchers critically evaluate the feasibility of online interviews within a particular African locality before fully implementing this data collection approach. Researchers may also collaborate with community-based organisations to help recruit a more socioeconomically diverse sample because of the potential of excluding participants with limited internet access.

Foreign policy change under authoritarian leaders: analysis of uzbekistan’s foreign policy in the post-cold war era

The growing study of foreign policy change offers various explanations of change and continuity in foreign policy. By focusing on the actors of foreign policy decision-making, past scholarship has mainly concentrated on the role of institutional and noninstitutional factors in foreign policy change. However, decentralized decision-making is more relevant to democratic regimes than authoritarian regimes. Despite the abundance of case studies on foreign policy making in nondemocracies, advancements in the conceptual understanding of foreign policy change in authoritarian regimes are still needed. Addressing Uzbekistan’s foreign policy, this article proposes an advanced framework to explain why and how foreign policy change takes place under authoritarian leaders. A leader’s perception of the external environment is argued to be a decisive factor inducing authoritarian leaders to (re)consider their regime survival strategy. Concern with regime survival, in turn, shapes foreign policy goals which are manifested in distinctive foreign policy behavior of a leader. Ultimately, the behavior of a leader translates into certain foreign policy outcomes.

Application of mixed hydrotropy in spectrophotometric analysis of frusemide in different formulations

The present study describes the use of an aqueous solution containing a blend of hydrotropic solubilizing agents (mixed hydrotropic substance’s solution) as a successful solvent system utilizing the concept of mixed hydrotropy for spectrophotometric analytical estimation of various conventional formulations as well as novel drug delivery systems. Frusemide, a poorly water-soluble drug, was estimated by application of mixed hydrotropic solubilization method. There was more than 15-fold enhancement in aqueous solubility of frusemide in a solution of blend of hydrotropic agents which consisted of 30% urea, 13.6% sodium acetate and 11.8% sodium citrate. This solvent mixture was employed to solubilize the drug from the fine powder of tablet formulations as well as the niosomes of frusemide. The selected λmax for spectrophotometric estimation was 333 nm. The hydrotropic agents used in the analysis and additives used in the manufacture of tablets and preparation of niosomes did not interfere in the analysis. Statistical data proved the accuracy, reproducibility and precision of the proposed method. The results suggested that proposed method is new, rapid, simple, accurate, and reproducible as well as employed aqueous solvent instead of organic solvents in estimation of drug from the dosage forms.

Development and validation of rp-hplc method for simultaneous estimation of levocloperastine fendizoate and chlorpheniramine maleate in their combined dosage form

A simple and rapid RP-HPLC method has been developed and validated for the simultaneous determination of Levocloperastine fendizoate and Chlorpheniramine maleate syrup formulation. Resolution of the analytes was achieved within 10min, employing a mixture of 10mM mobile phase Buffer (pH 6.5): Acetonitrile (50:50, % v/v) as isocratic mobile phase, pumped at 1.0mL/ min through a C18 column (5μm particle size). The detection wavelength for the analytes was 227nm. The system suitability parameters were found to be acceptable. The linearity of response (r2>0.999) in the appropriate ranges (from 50% up to 150% of the expected concentrations of the analytes in the formulations), method accuracy (RSD<2.0%), repeatability and intermediate precision (RSD<2.0%), were confirmed. Robustness result indicates that the methods performance can withstand small variations in method parameters. Satisfactory results obtained in terms of analyte recovery and RSD, while analyzing marketed pharmaceutical preparations. Hence the method can be useful for regular analysis of this combination in marketed syrup formulation.

Primary hypertension in young adults (18-40 years) in enugu state, southeast nigeria: a cross-sectional study

Background: Hypertension (HTN) is defined as a blood pressure (BP) ≥140/90 mm Hg. The prevalence and mortality from HTN, globally and locally, have been on the increase since the 1980s. This study aimed to detect young adults (18-40 years) in Enugu State who are hypertensive, in order to raise the awareness that HTN is also common in young adults. Its early diagnosis and management could help to reverse the trend in the number of cases of HTN in Nigeria which had been predicted could hit 39.1 million by 2030 if the present trend is allowed to continue. Methods: Participants were administered with structured questionnaire. Their BPs, heights and weights were measured using sphygmomanometer, stadiometer and scale balance respectively. Data were analyzed as proportions, Pearson product moment correlations and Chi square tests using MaxStat (version 3.60) statistical software. Results: The overall prevalence of HTN was 21.3%; 20.7% in the 18-29 years age group; 25.9% in the 30-40 years age group; 24.3%, in males; and 20.3% in females. Pearson product moment correlation coefficient r between age and HTN=0.462, between sex and HTN=0.328, between family history and HTN = 0.513, between salt intake and HTN=0.613, between BMI and HTN=0.152, between physical activity and HTN=0.293, between smoking and HTN=0.308. Conclusions: HTN in young adults is more common than previously thought and if unmanaged in early life usually progresses to HTN later in life.

Indian advertising demand in terms of cultural society

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.

Antitussive effect of some medicinal plants on sulphur dioxide induced cough in animal model

Humans have used natural products to treat different pathological conditions since immemorial. Numerous plants have been reported to have antitussive activity. Our present study aimed to evaluate the ethanolic extract of Arenaria serpyllifolia (Carophyllaceae, Whole plant), Caesalpinia pulcherrima (Caesalpiniaceae, Aerial parts) and Fragaria nubicola (Rosaceae, Whole plant) for antitussive activity at the doses of 200, 400 mg/kg in healthy albino rats. Cough is a symptom and defensive reflex of removing the toxic, irritating substances and pathogens from the larynx, trachea and bronchi. Cough is usually considered a disease related to the lungs. Several substances are responsible for the stimulation of cough reflexes. Among the most common are dust, histamine and bronchoconstriction. Arenaria serpyllifolia is a small annual herb commonly called Thyme-leaved sandwort, found in uncultivated land, arid meadows and cliffs. Caesalpinia pulcherrima is an ornamental plant, usually 2 m tall, known as a Peacock flower. Fragaria nubicola grows in wooded valleys, forest margins and meadows. It is commonly known as wild strawberry. These plants have been used traditionally for cough suppression by different societies. In this study, cough was induced by using the sulphur dioxide induction method. Animals were divided into eight groups of ten animals each, and all the drugs were administered orally. Group I was the control group, while Group II was the standard. A dose-dependent inhibition of cough was observed for all extracts. At 200 and 400 mg/kg doses, all three extracts proved highly significant compared to standard. So, it proves and supports the traditional use of plants for relieving cough.

Attitudes, knowledge, and obstacles regarding medical research among medical students at the faculty of medicine and health sciences, ibb university, ibb, yemen

Background and Objectives: Research by medical students in Yemen is limited both in terms of quantity and quality. In this light, the early recruitment of medical students into research activities can encourage them to become academically adept and professionally renowned physicians. Therefore, the aim of this study was to evaluate the knowledge, attitudes, and obstacles regarding medical research among medical undergraduates in the Faculty of Medicine and Health Sciences, Ibb University, Yemen. Materials and Methods: For the purpose of this study, a cross-sectional survey was conducted among medical students at the Faculty of Medicine and Health Sciences, Ibb University, Yemen. This survey involved medical students at their 3rd, 4th, 5th, and 6th academic years, who participated in this study from August 01, 2022, to September 30, 2022. The permission to conduct the survey was obtained from the Dean of the Faculty of Medicine and Health Sciences, Ibb University. The data gathered from the survey were analyzed using descriptive statistics. Results: About 174 (92.6%) respondents completed the survey questionnaire. The mean age of these respondents was 23.34 years. Notably, most of them demonstrated low levels of concomitant knowledge despite having positive attitudes toward medical research. Only a few students agreed with the following statements in the questionnaire: there is allotted time to pursue research (14.9% agreed); there is adequate training in research methodology (12.1% agreed); there are sufficient reward/motivations for participation in research (9.2% agreed); there is adequate training on writing a manuscript (9.2% agreed); there is adequate training on the performance of simple statistical analysis (10.4% agreed); research mentors are readily available (16.6% agreed); and it is easy to obtain a permit to conduct research from an institution (20.7% agreed). In addition, less than half of the respondents agreed with the statement that adequate medical research facilities exist in Yemen (39.1%). Conclusion: Most of the respondents in this study showed low levels of knowledge regarding research, despite having positive attitudes toward it. The primary barriers hindering research practices were the following: lack of allotted time to pursue research, lack of adequate training on writing a manuscript, and lack of training on the performance of simple statistical analysis. Moreover, the survey respondents noted a lack of research mentors and difficulties in getting approval for conducting research from their institution.

Pattern of drug prescribed and drug related problems among hospitalized elderly patients

Prescribing drugs for elderly patients is not an easy task since elderly patients are frequently with comorbid conditions. In Libya, there are no guidelines for the management of medications used in elderly patients and no specialized geriatric health institutions. The aim of this study is to assess the pattern of medication use among hospitalized elderly patients in Sebha Medical Centre and the drug-related problems associated with these patterns. This report is descriptive and retrospective cross-sectional study that is conducted at Sebha Medical Center during 2021. Potential drug-related problems were assessed based on the classification of Hepler and Strand. In this study, out of 195 participants, most of the patients have been given antibiotics (92%). The majority of patients have been prescribed anti-gastric agents, vitamins and anti-thrombotic agents which accounted for 75%, 62% and 55%, respectively. To less extent, anti-hypertensive agents, analgesics and anti-hyperlipidemics were reported by 45%, 43% and 38%, correspondently. Almost all the patients have at least one event of drug-related problem and more than three-quarters of the patients had more than one event of drug-related problems. The highest rate was untreated indications which were reported for 77% then followed by drug use without indication nearly a half of the events 48%. To fewer extent rates were reported: “in improper drug selection”, “drug interaction” and “adverse effects” which were reported for 25%, 23% and 18% of the total events, respectively. Almost all elderly patients have been prescribed antibiotics, analgesics and vitamins. Drug-related problems are predominant prevalent in the clinical practice at the center. This study highlights the importance of activation of clinical pharmacist interventions at hospitals which can contribute to reducing the chance of risk of drug-related problems events among hospitalized elderly patients and ensuring rational drug prescribing in the geriatric clinical settings.

Critical process parameters evaluation of modified nanoprecipitation method on lomustine nanoparticles and cytostatic activity study on l132 human cancer cell line.

This work was focused on identification and evaluation of process parameters of modified nanoprecipitation method, for fabrication of lomustine nanoparticles, with the aim of reducing cancer cell viability at low concentration of lomustine. The parameters controlling particle size, mostly in nanosize, were solvent/nonsolvent composition and emulsification speed of homogenizer along with aqueous phase volume. This controlled particle size is below 250 nm. The stabilizer concentration controlled particle size is within 68 nm ± 0.89 to 137 ± 0.94 nm with PDI 0.06 ± 0.008 to 0.25 ± 0.001. But, the stabilizer addition mode showed more uniform size distribution with PDI 0.085 ± 0.004. Entrapment efficiency was maintained well above 47 ± 0.23%. The drug release pattern was monophasic with controlled release over 24 hrs. In the method used, drug content was affected by ratio of polymer to drug to organic solvent, as well as homogenization speed and time. Percentage viable cells of L132 human lung cancer cell line remained, were only 5% at 100 μg/ml lomustine equivalent PLA nanoparticles.

Liposomes as carriers in skin ageing

Ageing is an inevitable phenomenon. Similar to other organs, skin is also subject to an intrinsic ageing process. Additionally, skin ageing is also influenced by various environmental factors. Existing conventional formulations have limited efficacy because skin serves as a rate limiting barrier for percutaneous absorption of drugs. This has led to the evolution of various novel drug delivery systems. Among these liposomes have received considerable attention due to the numerous advantages they offer. Liposomes, submicroscopic spherical vesicles, were discovered in 1960’s. Since then, they have gained popularity as potential carriers for drugs, diagnostics, nutrients, vaccines and other bioactive agents. Liposomes find applications in pharmaceutical, cosmetics and other industrial fields. Various topical actives that have been found to be efficacious in delaying the signs of ageing have been formulated as liposomes resulting in enhanced delivery, biocompatibility, and reduced toxicity. This review focusses on therapeutic use of liposomes in skin ageing.

Physicians' attitudes, expectations, and experiences about clinical pharmacists and the barriers they have in developing a collaborative relationship with them

The purpose of this study was to determine the attitudes, expectations, experiences, and barriers that physicians in Tripoli hospitals experienced when working alongside Clinical Pharmacists (CPs). A descriptive self-administered questionnaire was used for the study, and participants were selected from several Tripoli hospitals. Most of the respondents agreed that CPs are an essential part of patient care teams and that they have the legal authority to review a patient's medication regimen and response. More than half of respondents believe CPs must be responsible for the medications they prescribe to patients. Half of the respondents agreed that CPs should be encouraged to play a more active role in hospitals and other healthcare facilities. The majority of participants agreed that CPs should participate in managing drug side effects and almost half agreed that CPs can contribute to decisions about drug interactions. By a low agreement rate, 42.7% of respondents thought CPs were specially qualified to counsel patients on drug therapy. A similar low trend was observed, with 40.9% agreeing to provide pharmacists with additional responsibility and authority in clinical departments, in contrast, 54.5% expressed their concern about the clinical responsibility of CPs in clinical practice. A minority of physicians agreed that Physicians should consult pharmacists in selecting the best pharmacological treatment. At the same time, the majority think that pharmacists lack clinical skills and 61.8% feel that physicians are unable to communicate effectively with CPs. 43.6% acknowledged that the traditional opposition between the two professions was a barrier to interprofessional collaboration while the absence of pharmacy space in clinical settings was cited by 39.1%. A majority of respondents agreed that physicians and pharmacists may improve their interprofessional collaboration by raising their awareness about it. A minority of respondents thought that laws and regulations governing physician collaboration should be put in place to promote effective collaboration between physicians and CPs. The study discovered that although most physicians endorse the introduction of clinical pharmacy services in hospitals and believe that physicians and pharmacists can collaborate on many tasks, respondents were not as impressed with the CPs' performance and believed that they lacked the professionalism required to carry out clinical responsibilities successfully. To facilitate the growth of clinical pharmacy services, laws and regulations must be put in place.

Primary intraosseous xanthogranuloma in adult cervical spine: a case report of benign cause of lytic bone lesion

Lytic lesions in adult spine are a common manifestation of aggressive disease such as primary bone tumor, metastasis, myeloma, or infectious pathology. Xanthoma arising in the spine with purely intraosseous component is an extremely rare occurrence with only six cases reported in the adult population, none in the cervical region. We report the first case of primary xanthoma of the cervical spine in a 50‑year‑old male solely confined to osseous compartment. The imaging mimics of lytic lesion with expansile mass in adult spine are reiterated.
