Identification of bioactive compounds and toxicity study of araucaria columnaris bark extract on human embryonic kidney cell line

Plants produce a diverse range of bioactive compounds making them a rich source of different types of medicines. Ornamental plants are cultivated for adornment and to enhance the appearance of houses and also for commercial purposes. However, only very few of these ornamental plant species have found to be used in medicine and only little literature exit on their chemical and biological actions. In the present study, the evaluation of antimicrobial activities and identification of bioactive compounds using TLC and GC-MS of the A. columnaris bark extract were performed. In GC-MS bioactive compounds with medicinal value were identified, such as Benzoic acid, 1H-N-Hydroxynaphth (2,3) imidazole-6,7-dicarboximide, 2-Propenoic acid, 3-(4-methoxyphenyl), 1H-N-Hydroxynaphth (2,3-d) imidazole-6,7-dicarboximi. To prove the nontoxic nature of the plant, its crude bark extract was subjected to toxicity study using human embryonic kidney cell line. It reveal that the plant is minimal toxic to the human kidney cell line so usage of appropriate level will found to be safe and also carrying out some structural modification will help in the extraction of new drugs for pharmaceutical purpose.

Two-stage rfid approach for localizing objects in smart homes based on gradient boosted decision trees with under- and over-sampling

eveloping automated systems with a reasonable cost for long-term care for elders is a promising research direction. Such smart systems are based on realizing activities of daily living (ADLs) to enable aging in place while preserving the quality of life of all inhabitants in smart homes. One of the research directions is based on localizing items used by elders to monitor their activities with fine-grained details of the progress. In this paper, we shed the light on this issue by presenting an approach for localizing items in smart homes. The presented method is based on applying machine learning algorithms to Radio Frequency IDentification (RFID) tags readings. Our approach achieves the required task through two stages. The first stage detects in which room the selected object is located. Then, the second one determines the exact position of the selected object inside the detected room. Additionally, we present an efficient approach based on gradient boosted decision trees for detecting the location of the selected object in a real-world smart home. Moreover, we employ some techniques of over- and under- sampling with data clustering for improving the performance of the presented techniques. Many experiments are conducted in this work to evaluate the performance of the presented approach for localizing objects in a real smart home. The results of the experiments have shown that our approach provides remarkable performance.

Mechanism of ibuprofen release from chitosan granules

Attempts have been made to formulate controlled release drug dosage forms using chitosan as a release controlling polymer. Granules of combination of chitosan, hydroxylpropyl cellulose, lactose, starch and Ibuprofen were prepared by wet granulation method using 1.0% lactic acid solution. The granules were physico-chemically characterized in terms of density, porosity, angle of repose, carr’s index and housner ratio and was found to be free flowing with good compressibility. FTIR spectroscopy was used and confirmed that there is no interaction between the drug and the added polymers. In vitro release of Ibuprofen, in phosphate buffer at pH 7.4, showed a steady and slow increase in the percentage of drug released over 24 hours as the percentage of chitosan was increased in the formulations compared to that from commercial tablets which released over 80.0% of their content in only two hours. The kinetic analysis using different mathematical models of the data revealed that the release kinetics of the drug form these formulations is somewhere between diffusion controlled, Fickian (anomalous) and non-Fickian which refers to a combination of diffusion and erosion controlled release. Thus, the high correlation coefficient of the data of drug release from most granules when zero order kinetics was applied revealed that there is a constant drug release with time for 24 hours.

Association of covid-19 severity with vitamin d and blood group

Vitamin D is a hormone which plays a vital role in immune response regulation, including the prevention of inflammation and autoimmunity. Insufficient vitamin D may increase the risk of infection. Vitamin D deficiency is not the only factor linked to an elevated risk of COVID-19 infection. Recent studies have discovered a link between SARS-COV-2 infection risk and blood type. This study was aimed to examine the association of vitamin D and blood groups with the severity of COVID-19. A retrospective study was conducted on 224 confirmed COVID-19 patients, aged between 18 and 89 years old. Patients were divided into three groups (asymptomatic, moderate, and severe cases), and serum 25(OH)D concentration and blood group were analyzed for all the patients. Data of the severe cases were obtained from Souq Althalath Isolation Center, Tripoli, Libya, while moderate and asymptomatic cases were obtained from Abushusha Polyclinic and Aldahmani COVID Filtration Center, during 22nd February 2021 and 28th April 2021 and serum 25(OH)D concentration and blood group were statistically analyzed for all the patients. The percentages of males and females were found to be 47.3% and 52.7%, respectively. Disease severity was distributed as follows: 12.5% asymptomatic, 44.6 % moderate and 42.9% severe. Most of the severe cases had vitamin D deficiency (88.5%). Among the severely ill patients, 39.6% had blood group A and 09.4% had group O, while 22.9%, and 28.1% had blood group B and AB, respectively. In contrast, among the asymptomatic patients, only 7.1% had group A and 85.7% had group O. Overall, the difference in the distribution pattern of blood group in the three severity categories was highly significant (p < 0.001). The prevalence of Rh positivity among asymptomatic, moderate and severe cases was 78.6%, 76.0%, and 60.4%, respectively. This study concludes that insufficient vitamin D levels might influence the severity of COVID-19. COVID-19 patients with blood group A and those who are Rh-positive could be more vulnerable to developing COVID-19 severity.

Risk factors associated with preterm birth of women who gave birth in abia state university teaching hospital, aba, southeast, nigeria

Background: Preterm birth remains a leading cause of neonatal morbidity and mortality worldwide. Identifying its risk factors is essential for developing targeted interventions to improve maternal and neonatal health. This study investigated the sociodemographic, obstetric, medical, and lifestyle risk factors associated with preterm birth among women who delivered at Abia State University Teaching Hospital (ABSUTH), Aba, Southeast Nigeria. Methods: A hospital-based case-control study was conducted at ABSUTH. The study population comprised all the women who gave birth at the facility who met the criteria. Data were collected through structured interviewer-administered questionnaires and medical record reviews. Key variables included maternal age, education level, socioeconomic status, obstetric history, medical conditions, lifestyle factors, and antenatal care utilization. Descriptive statistics, chi-square tests, t-tests, and logistic regression were performed using SPSS version 25, with statistical significance set at p < 0.05. Results: A total of 9125 deliveries were recorded during the period of this study, including 1,962 cases (preterm births, <37 weeks gestation) and 7,163 controls (term births, ≥37 weeks gestation). Chi-square analysis showed significant associations between preterm birth and maternal age (p < 0.05), low education level (p < 0.001), low socioeconomic status (p = 0.0351), previous preterm birth (p < 0.001), short pregnancy interval (p < 0.001), hypertension (p < 0.001), diabetes (p < 0.001), infections (p < 0.001), smoking (p < 0.001), alcohol consumption (p < 0.001), and inadequate antenatal visits (p < 0.001). Logistic regression confirmed that hypertension, diabetes, infections, previous preterm birth, and inadequate antenatal visits were independent predictors of preterm birth. Conclusion: The findings highlight the multifactorial nature of preterm birth, with medical conditions, lifestyle behaviors, and inadequate antenatal care playing crucial roles. Early identification and management of these risk factors through improved maternal health services and health education may reduce the burden of preterm birth in the study setting.

Medication adherence in type 2 diabetes mellitus patients at several public health centers in banyumas regency

Diabetes mellitus (DM) is considered as ”the mother of all diseases" because it causes many complications. Knowing and measuring medication adherence may have a greater effect on DM patients. Several studies in Indonesia used a questionnaire scale to measure adherence, however they do not validate the study population, so it could still be found anomalous correlation analysis between adherence and clinical data even though it measured in the same country and scale. This study measure the adherence level of type 2 diabetes patients, evaluates the validity of the medication adherence scale, and analyze the correlation with the clinical outcome of type 2 diabetes patients in four health centers in Banyumas district. The study uses a cross-sectional design in Prolanis type 2 DM patients of January -April 2020. The adherence is measured by MARS-10, backward-forward translation method followed by content and internal validation. Clinical outcome is evaluated based on fasting blood glucose measurement. The results of the MARS-10 Gregory index analysis showed content validity in the high category (IG ≥ 0.8). The content validity showed the results of 9 questions with the value of r count> r table (n = 30, r table = 0.361). Reliability analysis showed Cronbach's Alpha 0.747> 0.6. The measurement showed 80.3% were adherent patients and 19.3% were non-adherent patients. Correlation analysis showed that there was no significant relationship (p> 0.05) between patient adherence and clinical outcome. Those results showed that type 2 diabetes mellitus patients in 4 health centers were categorized as adherent but not correlated with the clinical outcome. This was enabled due to the clinical outcome was simultaneously influenced by several factors: general factors, individual factors, and unpredictable factors.

Slu-pp-332 and related errα agonists: a focused minireview of metabolic regulation, and therapeutic potential

The global burden of metabolic disorders, including obesity and type 2 diabetes, necessitates innovative therapeutic strategies. SLU-PP-332, a synthetic agonist of estrogen-related receptor α (ERRα), has emerged as a promising exercise mimetic, demonstrating preclinical efficacy in enhancing mitochondrial biogenesis, insulin sensitivity, and energy expenditure. This brief review synthesizes current knowledge on SLU-PP-332 and related ERRα agonists, highlighting their molecular mechanisms, preclinical outcomes, translational challenges, and ethical considerations. ERRα activation by SLU-PP-332 upregulates peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), driving fatty acid oxidation and mimicking exercise-induced metabolic adaptations. However, pan-ERR activity raises concerns about off-target effects such as cardiac hypertrophy and hepatotoxicity. Despite robust preclinical data, clinical translation remains hindered by the absence of human trials and undefined long-term safety. Future research must prioritize isoform-selective agonist design, rigorous clinical validation, and equitable access frameworks.

Analysis of perinatal mortality in aden general hospital: a hospital-based study from yemen

Background: Perinatal mortality remains high in developing countries, including Yemen. However, information on perinatal mortality in Yemen is lacking. This study aimed to find out the perinatal mortality rate in Aden General Hospital and to analyze the causes of perinatal mortality. Materials and Methods: This descriptive study was conducted at the Obstetrics and Gynecology Department of Aden General Hospital during the period from January 1, 2003 to June 30, 2004. It was a retrospective study for the first 6 months (January–June 2003) and prospective for the remaining period (July 2003–June 2004). Results: During the study period from January 1, 2003 to June 30, 2004, there were a total of 3770 births at Aden General Hospital, out of which there were 2976 births during the period from January to December 2003 and a further 794 births in the 6-month period from January to June 2004. The perinatal deaths were 166 (4.4%) giving a perinatal mortality rate of 44/1000 normal deliveries. Further analysis showed a total of 105 perinatal deaths in 2003 with a perinatal mortality rate of 35.3/1000 normal deliveries and 61 deaths in the period from January to June 2004 with a rate of 77/1000 normal deliveries. Unclassified deaths including premature cases accounted for 29% (n=48) of all causes, followed by mechanical causes 36 (21.7%). The mechanical causes are divided as follows, 33 (19. 9%) due to fetal distress and 3 (1.8%) due to breech presentation. Uncertain origin causes accounted for 19.3% (n=32) of all cases of death and toxemia was observed in 16 cases (9.6%), while malformation was found in 13 (7.8%) cases. Conclusion: The perinatal mortality rate in our center was 44/1000 deliveries. The major cause of perinatal mortality was prematurity, followed by mechanical causes. The most of the mortalities occurred outside the health facilities (extra-hospital).

Knowledge, attitude, and practices towards covid-19: a cross-sectional study among nursing and midwifery students in jalingo, nigeria

ABSTRACT Background: The coronavirus disease (COVID-19) infection rate and mortality among Nigerian health care workers appear to be on the increase. Aside from health workers, it has caused millions of infections and deaths worldwide. This study determined the level of knowledge, attitude, and practices of nursing and midwifery students towards COVID-19 in a North-Eastern Nigerian state. Methods: A total of 156 respondents were involved in this institutional-based cross-sectional study, conducted after the lockdown period. A total of 17 questions were used to assess the KAP with knowledge appraised with 12 questions, attitudes with 2 questions, and practices with 3 questions. Results: The majority of the students (53.80%) possessed a good level of knowledge regarding COVID-19, while 40.4% had fair knowledge regarding COVID-19 with only 5.80% having poor knowledge of COVID-19. The mean knowledge of COVID-19 in this study was 9.40±1.353 with an overall 78% correct answer rate. A vast majority of the respondent (82.7% and 98.1%) had strong confidence in Nigeria and believed that the pandemic will soon be over, respectively. Only a few avoided large gatherings of people (30.8%) with the vast majority reporting to have worn a mask when going out (84.6%) and washing their hands with running water and soap frequently as recommended (73.1%). In multiple logistic regression analyses, the COVID-19 knowledge score (OR: 0.39-0.40, 95%CI: 0.26 – 0.62, P<0.05) was significantly associated with a lower likelihood of negative preventive practices towards COVID-19. Conclusions: The participants in this study showed good knowledge, positive attitudes, and good practices toward COVID-19. There is still a need to strategize and implement periodic educational interventions and training on infection control practices among healthcare workers including students.

Coronary artery dimensions as determined by intravascular ultrasound in an indian population

Background: Percutaneous coronary intervention (PCI) has remained one of the greatest treatment modalities of the spectrum of atherosclerotic coronary artery disease over the past few years due to its high efficacy and minimal invasiveness. The most common cause of stent failure is stenting under-expansion, which complicates PCI. Thus, it is tremendously important to perform PCI relying on the precise measurement of the size of the coronary artery obtained with the help of intracoronary imaging. There is limited data on the size of coronary arteries as measured by intravascular ultrasound (IVUS) in India and specifically in southern India. This study, conducted between January 2022 and March 2023, aimed to estimate the coronary artery dimensions, which can serve as a guide to PCI when intracoronary imaging is not available Methods: A sample size of 165 patients with proven coronary artery disease undergoing IVUSguided PCI during acute or chronic coronary syndrome were recruited, and coronary arterydimensions were measured in this research work. The mean arterial size and predictors of the arteries were reviewed. Results: A total of 165 patients with 590 coronary artery segments were recruited: the mean left main (LM), external elastic membrane (EEM) diameter, and cross-sectional area (CSA) were 4.92 ± 0.41 mm and 17.83 ± 2.88 mm2 proximal left anterior descending (LAD) artery, 3.75 ± 0.32 mm and 13.74 ± 2.45 mm2 the mid-LAD 3.42 + 0.28 mm and 10.65 + 2.08 mm2 the distal LAD 2.94 + 0.31 mm and 7.98 + 2.07 mm2 the proximal left circumflex artery (LCX) 3.62 ± 0.32 mm and 11.67 ± 2.36mm2, the distal LCX 2.91 ± 0. 33 mm and 8.98 ± 2.22mm2 the proximal right coronary artery (RCA) 4.17 ± 0.41 mm and 14.82 ± 2.78 mm2 the mid-RCA 3.85 ± 0.36 mm and 12.94 ± 2.44 mm2, the distal RCA 3.43 ± 0.30 mm and 11.08 ± 2.05 mm2, respectively. The predictor of most epicardial coronary arteries is body surface area (BSA) with positive linear correlation. Conclusions: Measurements of the coronary arteries obtained were comparable to the previous data on coronary artery size of Southeast Asia and Caucasian populations using IVUS. BSA is an independent predictor for the majority of epicardial coronary arteries with a positive linear relationship. Male gender and hypertension also positively correlate with larger coronary artery dimensions, while dyslipidemia leads to smaller coronary artery sizes. Neither diabetes nor smoking influences coronary artery size in the current study. Finally, the quantification of the size of the coronary artery will help the clinician to have a reference dimension in instances where there is no intravascular imaging available.

Iatrogenic pneumocephalus presenting as seizure: a rare case report

Pneumocephalus is a rare condition characterized by the presence of intracranial air, most commonly seen after head trauma or surgery. Although it is often asymptomatic, it can lead to serious complications such as tension pneumocephalus and seizures. This study presents a case of iatrogenic pneumocephalus and seizures that developed after a flap rotation operation in a patient with a history of craniotomy. An 82-year-old male patient presented to the emergency department shortly after flap rotation surgery with loss of consciousness and generalized tonicclonic seizures. Brain computed tomography revealed a left temporal bone defect and epidural air collection. Diffusion magnetic resonance imaging showed no acute ischemic lesion. The patient was initially started on levetiracetam, but due to side effects, he was switched to a combination of valproate and lamotrigine. The patient developed pneumonia during follow-up and was treated in the intensive care unit and discharged in stable condition. In patients who have previously undergone craniotomy, the risk of pneumocephalus should be considered even in minor surgical procedures, and early imaging should be performed when new neurological symptoms develop.

Vaccination coverage and timeliness among children aged 12-23 months in kongwa district, dodoma, tanzania

Children's vaccinations play a significant role in public health efforts, particularly in reducing morbidity and mortality rates among children worldwide. However, challenges such as the accessibility of healthcare facilities, misinformation, and perceptions continue to affect the achievement of immunization goals in Tanzania and other developing countries. Based on the need to protect the community from diseases that can be prevented by vaccination, this study aimed to assess vaccination coverage and timeliness among children aged 12-23 months who attended postnatal immunization clinics in the Kongwa district located in the Dodoma region, Tanzania. A quantitative cross-sectional study was employed, involving 200 children who visited vaccination clinics along with their caregivers. Data were obtained through a questionnaire prepared and vaccination cards. This current study revealed that 96.0% were fully vaccinated, with 4.0% partially vaccinated, while no children were found to be totally unvaccinated. Timeliness varied across vaccines assed vaccines: 75.0% of Bacillus Calmette-Guérin vaccinated on time, four doses of Oral Polio Vaccine ranged from 74.0-87.0% of on time vaccination. Three doses of the Pentavalent Vaccine and Pneumococcal Conjugate Vaccine had on-time vaccination rates ranging from 79.5% to 86.0%. Two doses of the Rotavirus Vaccine reached on-time rates of 84.5% to 86.0%. 60.5% of people received the Measles and Rubella vaccine, with 35.5% experiencing delays and 4.0% remaining unvaccinated. This study revealed that, despite the national efforts to improve vaccination rates for children, issues such as delays and incomplete immunizations persist. Strategies like community engagement, continuous training for healthcare professionals, and improving healthcare accessibility in remote areas should be reinforced to improve vaccination uptake in Tanzania.

Enhancing mechanical characteristics and cost-efficiency of composite materials through hybridization and nanoparticle incorporation

Lightweight materials are increasingly being used in engineering applications today. Composites are replacing traditional metallic materials in a variety of sectors, including aerospace, defence, and aircraft production, where there is a demand for structural materials with high strength-to-weight and stiffness-to-weight ratios. Natural fibre composites are also increasingly used in place of synthetic fibre composites in a variety of technical fields due to their affordability and environmental friendliness. In this particular study, Kevlar (Aramid fibres) is combined with other materials to improve the mechanical characteristics and impact resistance of composites. The only material that costs more than Kevlar is carbon fibres. The goal is to maximize mechanical qualities while utilizing the fewest amounts of pricey Kevlar fibres possible. The hand layup technique was used to create the hybrid composites, which included both natural and Aramid fibres. The performance of various mechanical properties was then assessed. In addition, a morphological examination was done to look at the interior structure of the composite materials that were examined. The results show that the hybrid composite, with or without the addition of nanoparticles, demonstrates great strength with little reliance on Kevlar fibres.
