Platinum complexes of N-donor ligands bearing sulfonamide groups as anti-cancer agents: A review
No full textCancer has become a major health problem globally, and the trend of developing metal-based anticancer agents has evolved due to the greater cytotoxicity displayed by the metal complexes studied recently, including platinum and other transition metals. Different groups of anticancer drugs are employed in a clinical setting to treat different types of cancers. Platinum complexes, particularly cisplatin, is mostly utilized to treat various cancers worldwide. Nitrogen donors such as diethylenetriamine, dipicolylamine, ethylenediamine, etc. have been widely employed in the synthesis of many of the ligands which in turn are used to synthesize the relevant metal complexes possessing various biological properties. Furthermore, sulfonamide group and derivatives of sulfonamide have been incorporated into these metal complexes due to the variety of pharmacological properties it possesses, such as antibacterial, anti-carbonic anhydrase, antiprotease activities, etc. Most of these novel sulfonamide derivatives possess in vivo and in vitro anticancer activities. Platinum complexes bearing sulfonamide groups that have been studied recently have demonstrated significant anticancer activity in vitro. The therapeutic application of these platinum complexes will depend on pharmacokinetic, pharmacodynamic and safety profile data obtained through the clinical trials. Most of the platinum complexes used in oncotherapy contain amines as ligands in their general formula. More research is needed for the development of the field by identifying the opportunities present in various aspects to discover more metal-based compounds to curb cancer worldwide.

Unveiling The Intricacies of Artisanal Mastery: Investigating Central Kandyan Temple Mural Paintings (With Specific Emphasis on Medawala Rajamaha Viharaya)
No full textAncient visual art can be described as a valuable archaeological tool that brings the objective and non-objective knowledge of past human culture to the present. It can reveal a multifaceted body of information about the knowledge, skills, technology, cultural relations, ethical activities, individual and social ideologies, social stratification and the nature of social institutions possessed by humans at that time. The temple mural art of the Kandyan tradition, which spread from the late seventeenth century AD to the nineteenth century AD and centered on Kandy, is a unique milestone in the history of visual art in this country. This article focuses on whether the painting art of the Central Kandyan style is truly just a visual art, or whether it was created with some conscious political, cultural, and social understanding. Furthermore, the article investigates a number of diverse areas such as the narrative of the paintings, the use of colors and lines, the creation of human figures, the creation of symbols and motifs, the means of continuous narration, the grammar used by the artist, and the technical skills of the artist, and through this, the uniqueness and mutuality of this art movement. This study will provide an analytical commentary based on the paintings of the Medawala Tampita Viharaya, which is one of the most prominent temples in the Kandyan tradition in terms of aesthetic value. The qualitative research method will be employed as the primary method, drawing information from painting studies, museum observations, interviews with art historians, and secondary sources such as books, magazines, and internet articles

A Historical Study of the Social Representation of the Prostitute Profession
No full textThe contribution of women is particularly significant when studying the social history of ancient Sri Lanka. From the very beginning of human social history, women have played an important role in social, economic, religious, and political spheres. In the context of ancient Sri Lankan society, not only the male segment but also the female segment attained equal status. Women had the freedom not only to care for children and manage household duties but also to engage in any profession of their choice. Among these, prostitution emerged as a profession as old as the beginning of human history, arising due to social needs and becoming institutionalized over time. Therefore, prostitution is referred to as the oldest profession in the world.The main research problem of this study is to examine the social status held by women within the profession of prostitution in ancient Sri Lanka. The primary objective of this study is to identify the social depiction of ancient prostitution. Secondary objectives include understanding the origin and development of prostitution, examining its moral dimensions, and analyzing its impact in preventing social misconduct.A qualitative research methodology was used for this study. The findings revealed that prostitution existed as a socially accepted profession in ancient society. Women engaged in this profession provided their services to society with dignity and under a structured system while enjoying their rights. As such, women involved in prostitution in ancient society were respected and, due to the dignified nature of their services, contributed to the creation of a disciplined society
Women’s Economic Participation in Sri Lanka: Challenges and Opportunities
No full textWomen’s economic participation is crucial for national development, yet Sri Lanka continues to experience a persistently low female labor force participation rate (LFPR) of 32.1% (Department of Census and Statistics, 2023), with a gender gap exceeding 40%. This study employs descriptive statistics and survey-based analysis to examine the key factors influencing women's employment, including education, marital status, workplace flexibility, and socio-cultural constraints. Using secondary data (2015-2023) and primary survey responses (N=300 women, N=50 employers), the study identifies major barriers such as childcare responsibilities, workplace discrimination, gender pay gaps, and sectoral employment disparities. Findings reveal that women are predominantly employed in low-paying sectors such as agriculture and services, while their representation in STEM, finance, and senior management remains critically low. The analysis highlights the urgent need for policy interventions, including stronger labor laws, enhanced childcare support, and workplace diversity initiatives to promote gender equity in employment. Additionally, entrepreneurship support and targeted education programs can help bridge the gap and create more opportunities for women in high-growth industries. Addressing these challenges through legal, institutional, and cultural reforms is essential for fostering an inclusive and sustainable labor market, ultimately contributing to Sri Lanka’s economic progress
Factors Influencing Cinnamon Production: Insights from the Karandeniya Divisional Secretariat area in Galle District
Get PDFThe spice industry is a major economic driver in Sri Lanka, with cinnamon playing a significant role in the country's foreign exchange balance. Despite a steady increase in the area cultivated with cinnamon from 2015 to 2020, production levels have not shown comparable growth. The Galle District, which includes the Karandeniya Divisional Secretariat, accounts for over 35% of the total cinnamon cultivation area in Sri Lanka. However, not all plantations in this region are equally productive, highlighting a disparity between cultivated area and yield. This research is original as it addresses a knowledge and geographical gap in understanding the factors influencing cinnamon production in Sri Lanka, particularly in the Karandeniya Divisional Secretariat area. Primary data were collected from 50 cinnamon cultivators using purposive sampling and a self-administered questionnaire, while secondary data were sourced from the resource profile published by the Karandeniya Divisional Secretariat. Data analysis was conducted using correlation and multiple linear regression analyses via IBM SPSS Statistics 20.0 software. The correlation analysis revealed that logistical and infrastructure-related factors, Policy and institutional factors and operational and managerial factors had a significant positive relationship with average annual cinnamon harvest per acre at the 0.01 significance level. The multiple linear regression analysis confirmed that logistical and infrastructural factors, policy and institutional factors, and operational and managerial factors significantly impacted the average annual harvest per acre. These findings indicate the importance of addressing these three key factors in policy development to enhance the productivity and sustainability of the cinnamon sector in Sri Lanka. The study emphasizes the need for targeted interventions in logistical and infrastructure improvements, better operational and managerial practices, and more supportive policy frameworks to boost cinnamon production and maximize its economic benefits
