Tomato lycopene is a natural antioxidant and can alleviate hypercholesterolemia

Lycopene of tomato wastes was extracted and determination. The level of tomato lycopene was 145.50 ppm. An aliquots of the concentrated tomato lycopene, represent 100, 200, 400 and 800 ppm; grade lycopene (200 ppm) and butylated hydroxyl toluene (BHT, 200 ppm) were investigated by the 1,1- diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. These compounds were administered to rats fed on hypercholestrolemic diet daily form 10 weeks by stomach tube. Serum lipid contents (total lipids, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol), oxidative biomarkers (glutathione peroxidase and malonaldhyde), the liver (aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase activities) and kidney (uric acid, urea and creatinine) function testes were measured to assess the safety limits of the lycopene in tomato wastes. The data of the aforementioned measurements indicated that the administration oftomato lycopene did not cause any changes in liver and kidney functions. On the contrary, rats fed on hyperchoestrolemic diet induced significant increases in the enzyme activities and the serum levels of total lipids, total cholesterol, low and high density lipoprotein and decreased levels of the glutathione peroxidase and malonaldhyde

A Novel 2D Feature Extraction Method for Fingerprints Using Minutiae Points and Their Intersections

The field of biometrics has evolved tremendously for over the last century. Yet scientists are still continuing to come up with precise and efficient algorithms to facilitate automatic fingerprint recognition systems. Like other applications, an efficient feature extraction method plays an important role in fingerprint based recognition systems. This paper proposes a novel feature extraction method using minutiae points of a fingerprint image and their intersections. In this method, initially, it calculates the ridge ends and ridge bifurcations of each fingerprint image. And then, it estimates the minutiae points for the intersection of each ridge end and ridge bifurcation. In the experimental evaluation, we tested the extracted features of our proposed model using a support vector machine (SVM) classifier and experimental results show that the proposed method can accurately classify different fingerprint images

Parenting Style and Suicidal Behavior: A Focused Review

Objectives. Parenting is the general child-rearing practice that has both long- and short-term impacts on the physical, emotional, mental, and social development of the children. We aims at seeing the relationship between parenting style and suicidal behaviors. Methods. A search was conducted in Medline, Embase, and PsychINFO to identify the articles assessing the relationship between different types of parenting styles and suicidal behavior. We included 32 articles in the review published from inception to search date. Results. Among the 32 studies, 27 studies used a cross-sectional study design, 17 were published between 2011 and 2020, and most of the studies included respondents with ages between 9 and 21 years. A wide variety of the used instruments to assess suicidal behavior, and parenting style was noted. Eight studies revealed that authoritarian parenting style is one of the predictors of suicidal behavior, while one study reported the authoritarian parenting style as a resilient factor. Both dominating and flexible parenting styles were associated with higher suicidal behavior, and two studies reported that the permissive style is a contributing factor to suicidal ideation among participants. Conclusion. This review identified the supportive notion that authoritarian parenting style has an association with suicidal behavior in adolescence, and later life. However, a prudential judgment is warranted due to the heterogeneity of study methods, population, contexts, and measurement tools

Attitudes and risk factors of pornography consumption among Bangladeshi university students: an exploratory study

Pornography is extensively produced, distributed, and used as a medium of entertainment around the world but has been little studied in Bangladesh. The present study examined the attitudes and risk factors of Bangladeshi university students’ pornography consumption. A survey was carried among 313 undergraduate students at Jahangirnagar University (Dhaka, Bangladesh). The study found that 72% of students consumed pornography at least once within their entire life, and approximately half of them were occasional consumers. Approximately two-thirds (67%) encountered pornography during high school, although females typically encountered pornography much later. Logistic regression analysis showed that pornography consumption was predicted by being male, living in a rural area, being in a relationship, engaging in online activities (such as using Facebook), and watching movies. Further research is needed to further determine the behavioral patterns and associated factors that influence pornography consumption among Bangladeshi students

Exploring Women’s Decision-Making Power and HIV/AIDS Prevention Practices in South Africa

Decisions regarding sexual and reproductive health significantly impact women’s health and their protection against HIV/AIDS and other sexually transmitted infections. These decisions also impact females’ ability to reach their reproductive goals. Women’s autonomy is recognized to be vital to women’s access to reproductive healthcare, the use of contraceptives, the capacity to avoid or receive treatment for STIs (including HIV), and other reproductive and sexual health issues. This research investigated the association between the decision-making power of South African women (of reproductive age) and their knowledge and practices regarding HIV/AIDS preventive measures. The present study used data from the South Africa Demographic and Health Survey 2016. A total of 8514 women aged 15–49 years who participated in the survey were used for this research. The mean age of the women was 30.21 years, with an SD of 9.86. Approximately 38.5% of the women decided on contraceptive use, and only 11.7% of women’s partners and 49.8% of respondents were jointly involved in the decision-making process of contraceptive use. All HIV preventive measures under study were statistically significantly associated with high decision-making power; the use of a condom by the husband or partner of the women was the most significant; husbands or partners of the women with high autonomy were three times more likely to use condoms

Panic buying research: A bibliometric review

Background: Panic buying has been reported during a period of crisis when people buy an extra amount of essential commodities and hoard them anticipating their future utility. As a newer entity, a bibliometric analysis would reveal the research gaps for further studies. We aimed to do a bibliometric analysis of researchers published on panic buying over the past two decades. Methods: A literature search was conducted in the SCOPUS database using the keyword “panic buying”. All published research in the English language between 1st January 2001 to 1st August 2021 was included in the analysis of this study. Results: We identified a total of 142 articles on panic buying published over the past two decades. There is an exponential increase in the publication on this topic during the COVID-19 pandemic (n=127). Majority of the articles were published from the United States (n=23), followed by the United Kingdom (n=20), and China (n=20). The Frontiers in Public Health and Journal of Retailing and Consumer Services published the highest number of articles (eight each). Arafat SMY published the highest number of publications as a single author (n=10) and Enam Medical College and Hospital, Bangladesh has the highest number of papers as an institution (n=10). Among all the publishers, Elsevier has published the maximum number of papers (n=38). Conclusion: There is an exponential growth of panic buying research during 2020-21. The global crisis of the COVID-19 pandemic has been attributed to the recent rise in panic buying research

Suicidal behaviors among undergraduate medical students in Bangladesh

Background: Suicide among medical students is a global public health concern; however, it is often addressed poorly in developing countries like Bangladesh. This study aims to examine suicidal behaviors among undergraduate medical students in Bangladesh. Methods: This cross-sectional analytical study was conducted between February and July of 2019. Data were collected from 583 MBBS students at Bangladesh’s public and private medical colleges. A convenience sampling method was used, and data were collected through a pretested semi-constructed questionnaire. Results: A lifetime suicidal ideation was found among 23.8% of the participants. Significant associations were found among lifetime suicidal ideation, plan and attempt with depression, comorbidity, and family history. Multivariable logistic regression models revealed that a family history of suicide attempts or death by suicide increased the odds six-fold for ideation, over sixfold for a plan, and threefold for an attempt. Females were twice likely to be susceptible to suicide ideation, plan, and attempt. Conclusion: Suicidality appears high among medical students in Bangladesh. Levels of depression, comorbidities, as well as substance abuse affect lifetime suicide ideation. A previous history of attempting or committing suicide in the respondent’s family increases the individual risk for ideation, plan, and attempt. Females are more vulnerable than males

Plasma concentrations of 25-hydroxyvitamin D among Jordanians: Effect of biological and habitual factors on vitamin D status

<p>Abstract</p> <p>Background</p> <p>Vitamin D is cutaneously synthesized following sun exposure (vitamin D₃) as well as it is derived from dietary intake (vitamin D₃and D₂). Vitamin D₂and D₃are metabolized in the liver to 25-hydroxyvitamin D (25(OH)D). This metabolite is considered the functional indicator of vitamin D stores in humans. Since Jordan latitude is 31°N, cutaneous synthesis of vitamin D₃should be sufficient all year round. However, many indications reveal that it is not the case. Thus, this study was conducted to determine the 25(OH)D status among Jordanians.</p> <p>Methods</p> <p>Three hundred healthy volunteers were enrolled in a cross sectional study; 201 females and 99 males. 25(OH)D and calcium concentrations were measured by enzyme linked immunosorbent assay and spectroscopy techniques, respectively. All participants filled a study questionnaire that covered age, sex, height, weight, diet, and dress style for females. Females were divided according to their dress style: Western style, Hijab (all body parts are covered except the face and hands), and Niqab (all body parts are covered including face and hands).</p> <p>Results</p> <p>The average plasma 25(OH)D levels in males and females were 44.5 ± 10.0 nmol/l and 31.1 ± 12.0 nmol/l, respectively. However, when female 25(OH)D levels were categorized according to dress styles, the averages became 40.3, 31.3 and 28.5 nmol/l for the Western style, Hijab and Niqab groups, respectively. These 25(OH)D levels were significantly less than those of males (p < 0.05, 0.001, 0.001, respectively). In addition, the plasma 25(OH)D levels of the Western style group was significantly higher than those of Hijab and Niqab groups (p < 0.001). Furthermore, dairy consumption in males was a positive significant factor in vitamin D status. Even though calcium concentrations were within the reference range, the Hijab and Niqab-dressed females have significantly less plasma calcium levels than males (p < 0.01).</p> <p>Conclusions</p> <p>Very low plasma 25(OH)D levels in females wearing Hijab or Niqab are highly attributed to low sunlight or UVB exposure. In addition, most of males (76%) and Western style dressed females (90%) have 25(OH)D concentrations below the international recommended values (50 nmol/l), suggesting that although sun exposure should be enough, other factors do play a role in these low concentrations. These findings emphasize the importance of vitamin D supplementation especially among conservatively dressed females, and determining if single nucleotide polymorphisms of the genes involved in vitamin D metabolism do exist among Jordanians.</p
