In recent years, the trend of growing vegetables on green roofs has gained momentum as a way of promoting agricultural sustainability in Dhaka City. Rooftop gardens become an important part of urban agriculture's recent rejuvenation and offer alternative spaces for urban markets to grow vegetable products. Green roofs create spaces for vegetable crop production, thereby creating opportunities for agricultural incorporation into urban communities. At present, however, vegetable production activities on rooftops are limited due to multiple challenges that need to be addressed before widespread implementation takes place. Rooftop agriculture can improve various ecosystem services, enhance the biodiversity of urban areas and reduce food insecurity. Food production from green roofs will help support and sustain food for urban communities and provide a rare opportunity to grow food efficiently in typically unused spaces. As human populations become more urbanized and urban consumers become more interested in local food for their families, the use of alternative agricultural production systems, such as green roof technologies, will increase in importance. While cultivating food on buildings is a key component of making cities more sustainable and habitable, green roofs are not the total solution for providing cities with food security. They should be viewed more as a supplement to other sources of food production in urban areas.

We aimed to assess mass media influence on changing the healthy lifestyle behavior of people during the early phase of the COVID-19 (coronavirus disease 2019) pandemic. Principal component analysis and stepwise multiple regression model showed that knowledge level, media credibility, and media check-in had the most considerable contribution to influencing community people’s healthy lifestyle.

AimA huge amount of information associated with the novel coronavirus disease 2019 (COVID-19) outbreak was circulated by mass media in Bangladesh. To date, there is no example on how the lifestyle of the community people in Bangladesh may influence mass media intervention during a pandemic. We aimed to assess mass media influence on changing the lifestyle behavior of people during the early phase of the COVID-19 pandemic. Subject and methodsAn online cross-sectional survey with a limited face-to-face interview among 2080 Bangladeshi respondents was conducted between March 26 and April 1, 2020. Datasets were analyzed through a set of statistical methods such as classical test theory assessment, principal component analysis, Pearson’s correlation coefficient, and stepwise multiple regression model. ResultsThe results showed that there was a positive significant relationship between the composite lifestyle score and the social media is trustworthy during the COVID-19 pandemic (r=0.508, p < 0.01), while there was a negative relationship between the composite lifestyle score of the respondents and the daily online media platforms usage in COVID-19 period (r=−0.201, p < 0.01). The results also disclosed that knowledge level, media credibility, and media check-in had the largest contribution to influence the changing lifestyle of the community people. We also found that social media was highly used media as expected during the COVID-19 outbreak while the administrative action has little influence on the changing lifestyle behavior.ConclusionOur outcomes stress the significance of the reliability of information shared via mass media outlets and practical strategies to counter misinformation during the COVID-19 outbreak.

For a few decades, bacteria called probiotics have been added to some foods because of their salutary effects for human health. Although only various clinical studies have been conducted, that probiotic could be feasible in obstructing and treating some leading diseases such as cardiovascular disease, hypertension, hypercholesterolemia, cancer & other potential diseases. Probiotics have been suggested to reduce cholesterol via various mechanisms without any deleterious effect on human health. Among their various effects, anti-cancer properties have been highlighted in recent years. Such effect includes suppression of the growth of microbiota implicated in the production of mutagens and carcinogens, alteration in carcinogen metabolism and protection of DNA from oxidative damage as well as regulation of the immune system. Outcomes from animals and human studies suggest a tolerable cholesterol-lowering action of dairy products fermented with adequate strain(s) of LAB (lactic acid bacteria) and bifidobacteria. Mechanistically, probiotic bacteria ferment food-derived indigestible carbohydrates to produce short-chain fatty acids in the gastrointestinal tract, which can then cause a reduction in the systemic levels of blood lipids by suppressing hepatic cholesterol synthesis and/or redistributing cholesterol from plasma to the liver. Besides, some bacteria may intervene with cholesterol absorption from the gut by deconjugating bile salts and therefore affecting the metabolism of cholesterol, or by directly embodying cholesterol which is then helpful for reducing coronary heart disease, including hypertension and hypercholesterolemia. In this review, we will focus mainly on reviewing existing studies concerning the effects of probiotic food in ameliorating health and treating diseases particularly cardiovascular diseases, hypertension, hypercholesterolemia & cancer.
