Evaluation of pulp and paper-making potential of Acacia melanoxylon based on chemical composition grown at Chencha, Ethiopia
Published on: 23rd November, 2022
The study aimed to examine the chemical composition of Acacia melanoxylon wood as a potential raw material for pulp and paper manufacturing. Samples of Acacia melanoxylon were taken systematically based on tree height at the bottom (10%), middle (50%), and top (90%) of market height. The sample was sorted, dried, milled, and sieved, and all chemical compositions were determined by the standards outlined in ASTM except cellulose and hemicellulose, which were determined by the Kurschner-Hoffer and alkali extraction methods, respectively. The results of the study showed that the overall average values of chemical composition along tree height levels were 45.02%, 21.94%, 23.79%, 5.52%, 3.24% and 0.48% for cellulose, hemicellulose, Klason lignin, hot-water solubility, alcohol-benzene extracts, and ash content, respectively. Except for hot-water extractives, the chemical composition of the bottom and top portions differed significantly. Generally, this study suggests that the chemical composition of Acacia melanoxylon wood is well suited for pulp and paper production.
Decline in human sperm parameters: How to stop?
Published on: 31st January, 2023
A large systematic review and meta-regression analysis found that sperm counts all over the world appeared to be declining rather than stabilizing. The decline in male sperm counts does not necessarily translate to a decline in male fertility. The cause of declining sperm counts remains unknown; however, several potential causative factors have been identified: 1. Chronic diseases: diabetes mellitus, hypertension; hyperlipidemia, hyperuricemia and skin Diseases & metabolic syndrome. 2. Environmental factors: bisphenol a; phthalates; heavy metals and heat. 3. Lifestyle: obesity, diet, tobacco, alcohol, marijuana, stress, reduced sleep & sedentary life. Addressing these causes is required to stop or decrease male fertility decline. Action to improve semen quality such as prevention & treatment of chronic disease, decreasing unhealthy lifestyle behaviors such as smoking, poor diet, or lack of physical activity & eliminating toxic environmental chemicals.
The prevalence and risk factors of chronic kidney disease among type 2 diabetes mellitus follow-up patients at Debre Berhan Referral Hospital, Central Ethiopia
Published on: 20th February, 2023
Background: Chronic kidney disease is a progressive loss in renal function that is more accepted as global public health importance and its magnitude is overgrowing in the least developed countries like Ethiopia. No data was found in Debre Birhan Central Ethiopia on the magnitude of chronic kidney disease among type 2 diabetes patients. Methods: Institution-based cross-sectional study was conducted among 327 at Debre Berhan Referral Hospital from March to June 2019 in Adult (≥ 18 years) type 2 diabetes follow-up patients who volunteered to give informed written consent were included in the study. Systematic random sampling was used. Data were collected by interviews using structured and pre-tested questionnaires. Descriptive statistics of the continuous and categorical variables were done. The bi-variable and multivariable logistic regression was done to show the net effect of explanatory variables on chronic renal disease. Results: A total of 327 study participants were involved in the final analysis. The Prevalence of CKD among type 2 diabetic patients was 15.9%. A significant association was found with age > 60 years [AOR 3.5 (95% CI 1.8-6.8)], alcoholic patients [AOR 2.4 (95% CI 1.2-5.1)], glycated hemoglobin levels above 7% [AOR 2.5 (95 CI 1.5-4.1)], higher level of LDL greater than 100 g/dl [AOR 2.7 (95% CI 1.9-4)] and lower level of HDL [AOR 2.9 (95% CI 1.4-6)].Conclusion: The magnitude of chronic kidney disease among type 2 diabetic follow-up patients was 15.9%. Estimated GFR should be determined for diabetic patients at regular intervals of time for earlier diagnosis of chronic kidney disease.
Three-phase partitioning for isolating peroxidase from lemon peels
Published on: 21st March, 2023
Background and objective: Peroxidase is an oxidoreductase that uses different compounds as substrates and thus can be utilized for different applications. The goal of this work is to isolate peroxidase from lemon peels using Three-Phase Portioning (TPP). Methods: TPP was set by adding varying amounts of salts and alcohol and the enzyme activity recovery was measured for each variable. Different parameters were optimized successively in order to achieve the highest enzyme activity recovery including salt type, salt concentration, pH, alcohol/crude extract ratio and type of alcohol and then, combining all optimized conditions together.Results: Salt that gave maximal recovery was sodium potassium tartrate, optimal salt concentration was 15%, optimal pH was 8, optimal alcohol/crude extract ratio was 1 and t-butanol was preferred to 1-butanol. Efficiently, upon combining all optimized factors, an activity recovery of 175% was obtained.Conclusion: This protocol provides an easy, feasible method to efficiently isolate peroxidase from lemon peels using TPP.
Cognitive behavioral therapy treatment for drug addiction
Published on: 17th April, 2023
Drug addiction remains a major health concern following its devastating consequences to the users and the economy. Current statistics show a rising trend in substance abuse around the globe with approximately 284 million people engaging in drug abuse. Various approaches are used to treat the victims of drug abuse. Cognitive behavior therapy, a form of nonpharmacological intervention, has also been shown to be an effective treatment option for drug addiction. The use of Cognitive Behavioral Therapy (CBT) has grown since the 1970s to become one of the most important models of psychotherapy in this decade. Various empirical studies have shown the efficacy of CBT in well-controlled trials. A total of 19 randomized trials (cases) (with over 1400 patients treated) were selected and studied. In the various cases, results showed that patients were treated for drug and substance abuse disorders with the majority being those who abused cannabis, cocaine, alcohol and other opioids. In most cases, the CBT techniques that were used for drug addiction included cognitive restructuring, relapse prevention and contingency management. Components of CBT for drug addiction include skills and training, amplification of non-substance-related activities, approaches for managing urges, drug rejection and improvement of social aptitudes. Cognitive restructuring focuses on the identification of misconceptions and influencing the way people think about themselves by eliminating distorted thinking. Relapse prevention focuses on the identification and prevention of high-risk situations that may trigger the patient to engage in drug abuse. Contingency management reinforces positive behaviors and reduces negative behaviors through the use of rewards and incentives.
Sleep quality and Laboratory Findings in Patients with Varicose Vein Leg Pain
Published on: 24th June, 2023
Aim: This study aimed to investigate the association between sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI), and laboratory findings in patients presenting with the complaint of leg pain due to varicose veins.Materials and Methods: A total of 160 patients with leg pain were included in this study. Sleep quality was assessed using the PSQI, and laboratory tests were conducted to evaluate ferritin, iron, vitamin B12, Thyroid Stimulating Hormone (TSH), C-reactive protein (CRP), albumin, low-density lipoprotein (LDL), and hemoglobin levels. Statistical analyses were performed using the independent t-test or Mann-Whitney U test for continuous variables and the chi-square test for categorical variables.Results: Patients with poor sleep quality had a significantly higher prevalence of leg pain complaints compared to those with good sleep quality (p < 0.001). Females were more likely to report poor sleep quality (p = 0.006). No significant associations were found between sleep quality and age, smoking status, alcohol use, or pack/year of smoking. Patients with poor sleep quality had significantly lower ferritin levels (p = 0.008), lower albumin levels (p = 0.031), and lower hemoglobin levels (p = 0.036) compared to patients with good sleep quality. However, no significant differences were observed in other laboratory parameters.Conclusion: The findings suggest a significant association between poor sleep quality and leg pain complaints in patients with varicose veins. Lower ferritin, albumin, and hemoglobin levels in patients with poor sleep quality may indicate potential underlying mechanisms linking sleep quality and leg pain. Addressing sleep quality issues in patients with leg pain could improve overall well-being and treatment outcomes.
Internet Addiction and its Relationship with Attachment Styles Among Tunisian Medical Students
Published on: 13th July, 2023
Internet addiction is a growing addictive behavior and a major public health problem worldwide. Several psychological factors can contribute to the problematic use of the Internet. This study aimed to determine the prevalence of Internet Addiction (IA) in a sample of university students and to examine the relationship between IA, self-esteem, and attachment styles.The present study was a cross-sectional study, involving 135 students from the Faculty of Medicine of Monastir. The participants completed a questionnaire, which contained the socio-demographic data, the reasons for Internet use, the Young Cyberaddiction scale to seek IA, the Relationships-style-questionnaire-RSQ to assess attachment style, and the Rosenberg Self-Esteem Scale (RSES).The mean age of the students was 21.5 ± 1.9 years old. They were 112 (83%) females. The prevalence of Internet addiction was 23.7%. The average connection time was 3.5 ± 1.8 hours/day. The most frequent online activities were chat (online discussion, forums ...) in 94.8% of cases followed by download activities (78.5%), scientific research (75.6%), online games (23.7%), and online shopping (13.3%). IA was associated with school failure, alcohol use, online gaming, and low self-esteem. The majority of the participants (84.4%) in this study reported an insecure attachment style. Logistic regression analysis showed a strong association between IA and fearful attachment style.IA was frequent among students. Fearful attachment style was found to be a risk factor for IA. This study highlights the impact of relationships between child and their caregivers on the development of addiction.
Microbial Conversion and Utilization of CO2
Published on: 4th September, 2023
Rising greenhouse gas emissions have contributed to unprecedented levels of climate change, while microbial conversion and utilization of CO2 is a practical way to reduce emissions and promote green manufacturing. This article mainly summarizes several natural CO2 pathways that have been discovered, including the Calvin cycle, the reduced tricarboxylic acid (rTCA) cycle, the Wood–Ljungdahl (WL) pathway, the 3-hydroxypropionate/4-hydroxybutyrate (HP/HB) cycle, the dicarboxylate/4-hydroxybutyrate (DC/HB) cycle, the 3-hydroxypropionate (3HP) cycle, the reductive glycine (rGly) pathway, and artificially designed carbon fixation pathways includes the CETCH cycle, the MOG pathway, the acetyl-CoA bicycle, and the POAP cycle. We also discussed applications of different carbon fixation enzymes, notably ribulose-1, 5-diphosphate carboxylase/oxygenase, pyruvate carboxylase, carbonic anhydrase, as well as formate dehydrogenase. This paper further addressed the development of photosynthetic autotrophs, chemergic autotrophs and model bacteria Escherichia coli or yeast produced main products for CO2 fixation through metabolic engineering, such as alcohols, organic acids, fatty acids and lipids, bioplastics, terpenoids, hydrocarbons, and biomass. Future studies on CO2 microbial conversion should focus on improving the efficiency of carbon fixation enzymes, metabolic modules of the carbon sequestration pathway, and intracellular energy utilization. Coupled microbial and electrochemical methods for CO2 fixation, in addition to biological fixation, show considerable promise.
Stroke Mimics: Insights from a Retrospective Neuroimaging Study
Published on: 27th September, 2023
Objectives: The study’s goals are to evaluate the management of Stroke Mimics (SMs), conditions with stroke-like symptoms but non-vascular origins. It seeks to avoid the unnecessary intravenous thrombolysis, the target therapy delays and determine the best SMs diagnosis approach.Materials and methods: A review was conducted of all patients admitted to the Emergency Department under a “stroke code” from January 1, 2018, to January 31, 2019. Anamnestic and clinical data, along with information on neuroimaging protocols and findings, were collected. Advanced MRI sequences, such as Arterial Spin Labeling (ASL) MR perfusion and MR spectroscopy, were revised to confirm the diagnoses.Results: 513 stroke codes were found; a neurovascular disease was diagnosed in 414 cases: 282 ischemic strokes and 73 intracranial hemorrages and 59 TIAs. The 99 SMs included, 13 infections, 12 syncopes, 11 epileptic seizures, 11 hemodinamic conditions, 10 tumors, 9 metabolic disorders, 9 diziness, 7 migraines, 4 drug/alcohol intoxication, 3 functional disorders, 3 acute hydrocefalus, 2 multiple sclerosis, 2 arteriovenous malformations, 1 spinal cord compression and 2 unexplained conditions. Specific neuroimaging findings were evaluated for all cases. Positive and negative predictive values of clinical diagnosis of SM were respectively 0.23 and 0.35. 125 SM patients underwent MRI examination, 40 of which within 3 hours from the activation of stroke code. Advanced MRI sequences as ASL, MR perfusion, MR spectroscopy were used to reach the correct diagnosis.Conclusions: Advanced multimodal MRI can be a valuable tool in the assessment of, particularly in cases where conventional imaging techniques such as DWI-FLAIR mismatch are inconclusive. The novelty of this retrospective study is to demonstrate that the consistent use of arterial spin labeling perfusion in cases with stroke code leads to a rapid and accurate diagnosis of SMs. The implementation of an MRI-based pathway can expedite the diagnosis and treatment of underlying non-vascular causes such as SMs.
Qualitative Identification of Secondary Metabolites and Determination of the Toxicity of Extracts Obtained from the Flower of Kalanchoe Pinnata
Published on: 17th October, 2023
Kalanchoe pinnata, also known as air leaf or life leaf, is a plant used in traditional medicine in different world regions. In Mexico, it is included in the Atlas de la Medicina Tradicional Mexicana with a wide variety of applications, such as antimicrobial, anti-inflammatory, anticancer, and antihistamine, among others. However, neither a secondary metabolite profile of the flower has been reported nor information on its possible toxicity. The latter is the purpose of this work. A phytochemical profile of extracts with solvents of different polarity (aqueous, methanol, ethanol, and ether) was carried out. In this profile, the structural compounds could be qualitatively determined by chemical reactions, and some changes in coloring or precipitation were observed. The acute toxicity test of the extracts was performed with an aquatic organism, Artemia sp, and a terrestrial organism Eisenia foetida, as well as the evaluation of the antioxidant capacity of the extracts in the organism of Eisenia foetida. The ABTS radical method and TROLOX were applied as synthetic antioxidants for the evaluation of the inhibition percentage. Most important secondary metabolites were qualitatively identified in the extracts of K. pinnata flowers. Mainly in the alcoholic extracts (methanol and ethanol) tannins, alkaloids, and flavonols were found. As mentioned above, they are reported to have toxicological effects. The toxicity and antioxidant activity tests confirm the preliminary results obtained in the identification of secondary metabolites. It is therefore concluded that the flower of Kalanchoe pinnata contains secondary metabolites that may be of great therapeutic interest.
Bleeding from Varices: Still a Heavy Burden in Patients with Cirrhosis
Published on: 27th December, 2023
Introduction: Bleeding from varices is a severe complication in patients with cirrhosis. Despite its treatment has been well established in the last three decades the mortality can be still high. This study compares the epidemiological features and the bleeding-related outcomes of a group of patients published about ten years ago with a more recent group of 168 consecutive patients. Methods: The diagnosis, the treatment, and the main outcomes (5-day failure, 5-day and 6-week rebleeding, 5-day and 6-week mortality) of variceal bleeding were evaluated according to the current guidelines.Results: The number of patients with cirrhosis admitted for variceal bleeding every year has progressively decreased in the last ten years. The age sex and severity of liver disease, evaluated with Child Pugh and MELD scores, were comparable in the two series. In the more recent series, there were significantly fewer patients with HCV infection and more patients with alcohol-related cirrhosis. The main outcomes of bleeding were comparable too. Overall, at 6 weeks 36.4% of patients did not overcome the bleeding episode. Conclusion: The decreasing incidence of bleeding from varices is likely attributable to antiviral treatment of HCV and HBV and the larger diffusion of beta-blockers in primary prophylaxis. Despite the larger application of the gold standard therapy, the mortality of variceal bleeding remains high in patients with cirrhosis.
Porphyria Cutanea Tarda (PCT) in a Patient, Treated with Hemodialysis after a Kidney Transplant Rejection Reaction: A Case Report
Published on: 18th March, 2024
Porphyrias are a group of inherited metabolic disorders of haem biosynthesis, involving a deficiency in the enzyme uroporphyrinogen decarboxylase. In this case report we present a case of a patient with porphyria cutanea tarda (PCT). A 40-year-old man on hemodialysis after a kidney transplant rejection reaction, complaining of skin changes, with a history of smoking and alcohol intake. Treated with Fusidic acid Betamethasone cream, and erythropoietin. Porhyria cutanea tarda can be considered in a patient who complains of skin changes. History of alcohol intake, smoking, high ferritin levels, and increased hepatic markers can raise suspicion of disease. In patients with ESRD treatment with erythropoietin, SPF 50+ sun cream, Fusidic acid, and Betamethasone can be effective.
Alcohol and Substance Abuse in the General Population during the COVID-19 Pandemic: Results of the COMET-G International Study
Published on: 15th April, 2024
The global impact of the COVID-19 pandemic on mental health and substance use behaviors has sparked extensive research efforts. The COMET-G international study, organized by the Department of Medicine and the Rectorate of the Aristotle University of Thessaloniki in collaboration with the World Psychiatric Association, delved into these issues. Running from March 2020 to April 2021, the study collected responses from 55,589 individuals across 40 countries. Through a comprehensive questionnaire, participants provided insights into their mental state, attitudes toward the pandemic, and the resultant changes in their personal and daily lives. Findings revealed, among other things, significant patterns of change in substance use, with notable correlations between reduced usage and the severity of lockdown measures among non-binary individuals. Mental health history emerged as a strong predictor of substance use changes, with influences from anxiety disorders, depression, and self-harm. Additionally, family and social dynamics, including economic expectations and household composition, significantly shaped substance use behaviors during lockdowns. Given these findings, the development of comprehensive approaches targeting the adverse effects of the pandemic on individual behaviors and general welfare is crucial.
Chronic Ethanol Decreases the Left Ventricular Cardiac Performance
Published on: 15th April, 2024
Introduction: Spaced fiber bundles, less evident cell striations, deposition of collagen fiber bundles, and increased presence of fibroblasts in the cardiac tissue of rats that voluntarily and chronically ingested ethanol were observed by our research group. In addition, we observed increased proliferation and cell death of cardiomyocytes. To find out whether these changes lead to impaired heart functionality, some clinical tests were performed. Aim: to investigate whether chronic ethanol decreases the left ventricular performance assessed by exercise testing, electrocardiogram, and echocardiogram of male and female UChB strain rats. Material and methods: ten adult males and ten adult females, Wistar strain rats, named UChB (University of Chile), spontaneous high ethanol drinkers (consumption greater than 2 g ethanol / Kg body weight/day), and ten male UChB rats and ten adults female UChB rats, not exposed to ethanol, UChBC rats (controls) were used. Cardiac performance was evaluated by the stress test, electrocardiogram, and echocardiogram. Results: Exposed females showed ventricular morphological changes in the heart. The exposed females and males had the highest heart relative weight with females being larger than males. The exposed females showed altered electrocardiogram and echocardiogram. Conclusion: Chronic ethanol decreases the left ventricular cardiac performance in rats. Females are more sensitive to changes in cardiac electrical conduction.
