Introduction Prostate cancer (PCa) is a significant health issue affecting males globally and is the second most common cause of cancer-related mortality in males. Diet and physical activity can affect the possibility of getting PCa. Traditional plant-derived compounds and natural products have demonstrated promising effects against PCa in clinical settings. These natural products possess various antitumour qualities and have shown to be safe, inexpensive, and well-tolerated. Objective The objective of this review is to thoroughly assess and describe the most recent studies on natural products and their multifunctional roles in PCa therapy methods. In order to evaluate the efficiency and safety of these natural compounds in clinical settings, it is important to understand the underlying molecular mechanisms, identify prospective molecular targets, and regulatory molecules. Methodology In 2023, our team conducted thorough searches across multiple databases for studies published from 1990 to 2023, with a major emphasis on 2010–2023, using specific keywords and headings related to natural products and PCa. We included relevant older studies published as early as 2000. Original articles and review papers were included as part of the criteria. Result The results showed that natural compounds, plant extracts, nutraceuticals, and marine products hold great potential as therapeutic approaches for PCa. Compounds like quercetin, fisetin, genistein, sulforaphane, epigallocatechin-3-gallate, ginsenosides, silymarin, berberine, celastrol, and honokiol have shown inhibitory effects on the androgen receptor axis, similar to synthetic drugs. Additionally, compounds such as quercetin, luteolin, apigenin, curcumin, sulforaphane, and genistein have demonstrated promise in targeting PCa stem cells. Nutraceuticals like green tea, legumes rich in phytoestrogens, tomatoes with lycopene, buckwheat containing quercetin, and guava rich in phytochemicals have exhibited antiprostate cancer effects by inhibiting cancer cell proliferation, inducing apoptosis, and displaying antioxidant properties. Moreover, marine products, including compounds like discorhabdin C, 1386A, frondoside A, and marinomycin A, have displayed potent anticancer activity against PCa cells by triggering apoptosis and exhibiting cytotoxic properties. Conclusions These findings highlight the promising role of natural compounds, plant extracts, nutraceuticals, and marine products in developing innovative therapeutic strategies for PCa. However, further research is needed to better understand their mechanisms of action, evaluate their efficacy and safety in clinical settings, and determine optimal dosages and treatment regimens.
STUDY ON THE FACTORS AFFECTING THE AVAILABILITY OF MARINE DRY FISHES IN CHITTAGONG, BANGLADESH
(Dept. of Coastal and Marine Fisheries, 2013-12) Begum, Rabeya
Marine fishes contributing a very momentous role in the fisheries sector which is a paramount sector especially for the coastal community for their living. Both fresh and dry fishes are playing their essential role in the economy of coastal as well as whole Bangladesh. But there is a huge gap between species composition and quantity of fresh and dry marine fish species availability. Several factors are caused for the gap. So, the study was conducted in two seasons like as monsoon and post-monsoon to observe the different factors that influenced the availability of marine fresh and dry fish species in Chittagong region. Primary data were collected from the selected study areas by questionnaires and interview methods and also observed the related factors, which influenced the variation in species composition of dry and fresh marine species. Present study identified a total of 64 species of finfish and shellfish in the Chittagong region in fresh condition where 28 species of finfish and shellfish were available in dry condition during the study period. The study also identified that seasonal variation is the main factor, which influences the species availability. Harpodon nehereus was the most dominated species in both fresh and dry condition in all seasons. Sun drying and improved solar drying are the main methods practicing for drying of fish in the study area. Climate change, political conflicts, financial crisis, etc. mentioned as major constraints in the drying industry.
T. S. Eliot and Shamsur Rahman: An Exposition of Commonness
(University of Rajshahi, 2009-06-28) Adhikari, Prodip Kumar; Sarker, Swarochish; Begum, Rabeya
The present study has been conducted to expose the commonness between T. S. Eliot and Shamsur Rahman, two leading modernist poets in their respective language and literature. The objectives of the exposition have been grounded on the areas and nature of commonness; in exploring into the originality of their work; in identifying the level of influence of the former on the later one here; and finally in showing the contribution and potentiality of their work in our life and literature of the present day. In the study only the poetical works of these poets have been used to find out the commonness in their poetry. While conducting the study the present researcher has found some major affinities in the choice of subject matter; use of contemporary social perspectives; in presenting the verse style or the way of versification etc. Some minor affinities have also been found in the case of their personal life likely their education, profession. All these have been presented through six chapters including a concluding one. The first chapter is the Introduction chapter. Here they’re including a short overview on the modernist trend in literature. Here present researcher has described in short, the literature reviewed, and methodology of the research work too. The second chapter entitled “Life and works of T. S. Eliot: towards the components of commonness,” contains life-sketch of T. S. Eliot, academic career of T. S. Eliot, profession and marital life of T. S. Eliot, development of T. S. Eliot’ s poetic thoughts, features of his poetry. The third chapter entitled “Life and works of Shamsur Rahman: towards the components of commonness,” likewise the second chapter describes on Shamsur Rahman. It is divided into some seven sub-chapters including introduction and conclusion. Here Eliot’ s brief life -sketch, his academic life, profession and marital life, development of his poetic thoughts and features of poetry etc, have been described. Chapter four entitled “Poetic Commonness between T. S. Eliot and Shamsur Rahman,” is the main part of the research work. Here the areas of commonness between the two poets have been shown with references throughout several sub - chapters. The present researcher has pointed out various areas of affinities with special importance on the modernist trend in poetry and the position of T. S. Eliot and Shamsur Rahman in their respective language and literature; their appeal and recognition as urban poets among the readers; their way of presenting a world of rootless souls; presenting a psychological dilemma of modem man with his split personality. It also the researcher has highlighted on a world of demythologized posterity, the theme dominating the major part of T. S. Eliot’ s poems and also a vitalized area in Shamsur Rahman’ s poems. Chapter five entitled, “Sharings, Shortcomings and Shaping a world of novelty: Eliot and Rahman,” is designed to expose the commonness in the poetic diction of the two poets; to find out affinities in these areas where Shamsur Rahman has direct or indirect bearing from Eliot. Chapter six is the concluding chapter of the research work where the researcher has summarized the entire theme of the research. Again, the potentiality of the poets for their thinking alike nature like all the great men of the world has been taken into consideration as a greater commonness between the two poets. Finally, an index has been designed and added to this work where the present has presented an annotated bibliography. Shamsur Rahman’ s poetical works included in the three volumes entitled Kabita Samagra -1; Kabita Samagra -2; Kabita Samagra-3 have been presented through transliteration and translation. If there is any Romanisation given in case of book or publishing house’ s name that has been followed accordingly.
