Annonamuricata plant parts possess a broad range of medicinal and biological properties. This research compared the chemical composition and antioxidant properties of Annonamuric at aparts. Proximate, mineral, total phenol and total flavonoid content as well as invitro antioxidant activity were examined. Results revealed the leaves contained significantly(p<0.05) higher composition of moisture (8.69±0.22%), ash (4.60±0.02%), protein (14.53±0.11%), crude fat (10.28±0.03%),chromium (0.38±0.05 mg/100g), nickel (1.75±0.04mg/100g), total phenol (1.01±0.03mgpyrocatechol/mL) and total flavonoid (1.12±0.03mgGAE/mL)compared to the respective values for root. Carbohydrate (9.29±0.24%), lead (0.13±0.02mg/100g) and cobalt (1.93±0.02mg/100g) composition was significantly lower(p<0.05) in the leaves compared to the respective compositions in the root. The leaf and root extract exhibited a concentration-dependent increase in hydroxyl radical scavenging activity with no observable(p<0.05)difference in their EC50 value. This study suggests the leaves of A. muricata found in Covenant University had better chemical composition when compared to the root. Nonetheless, these plant parts may be further exploited for not only their nutritive composition and mineral content but also a natural source of antioxidant agents.

Ulcers are one of the dreadful and technically known as Peptic Ulcer Disease (PU Disease). Around 10million people around the world are suffering from the disease, and the majority of the people are about 20-50 years of age. This is not a dangerous disease on its own. Still, the ulcers are responsible for the resulting in other diseases like indigestion stomach pain etc. there are various reasons for the causation of ulcer. They are excessive use of pain killers and anti-inflammatory drugs, malnutrition, and unhealthy food habits, stress and steroids. Almost half of the world population relies on herbs for the treatment, and the major sources of the chemical leads that treat diseases are in the medicinal plants only. Many plants have been investigated and reported for their potential antiulcer benefits and are published too for that. The plant parts of Malvastrum tricuspidatum were extracted using distilled water and were investigated for the antiulcer activity in 3 doses like 100,200 and 400mg. The Extract at a higher dose showed better activity than other lower doses. The activity was compared with the standard drug and showed a significantly better activity that the standard and other doses of Extract too.

The dangers of mass emergencies are greater today than ever before in the history of man. The reasons are:1) The exponential growth of the world population from 2 billion in 1925 to 4 billion today and to an expected 8 billion in the year 2025. This growing population is badly in need of more and more food and energy to sustain itself.2) The increasingly severe competition world-wide for the available supplies of food and energy will precipitate mass emergencies and even mass disasters. Some of these mass disasters, such as nuclear war, have the potential to destroy entire countries…or even the human race itself.No matter how gloomy the outlook is, however, it is still the task of the medical profession to recognize this growing danger and to do everything possible to be prepared for and treat not only individual emergencies, but mass disasters as well.

Stinging Nettle

This research aimed to determine the effect of different harvesting times on the chemical composition of stinging nettle (Urtica dioica L.). The leaves of nettle were harvested at the same place once a month in the period of April–September 2019. The analysis focused on the contents of dry matter, soluble solids, ascorbic acid, titratable acidity, chlorophyll a and chlorophyll b, total carotenoids, total phenolic compounds, antioxidant activity, ash content, and macro- and microelements. The nettles harvested in April were characterized by the highest levels of soluble solids and some macro-and microelements (P, K, Fe, Zn). The plants harvested in May were distinguished for titratable acidity, chlorophyll a, chlorophyll b, and carotenoid contents. In this month, the plants were determined to have the highest antioxidant activity during the entire vegetation period. The plants collected in July contained the highest amount of Mn, but the antioxidant activity of these plants was the lowest during the vegetation period. In August, the plants had the highest levels of ascorbic acid, phenolic compounds, and ash, while the plants collected in September were characterized by having the highest amounts of Ca, Mg, and B as compared to those established in other months of vegetation.

National Human Rights Institutions

In the last six decades, one of the most striking developments in international law is the emergence of a massive body of legal norms and procedures aimed at protecting human rights. In many countries, though, there is little relationship between international law and the actual protection of human rights on the ground. This book takes a fresh look at why it's been so hard for international law to have much impact in parts of the world where human rights are most at risk. The book argues that more progress is possible if human rights promoters work strategically with the group of states that have dedicated resources to human rights protection. These human rights “stewards” can focus their resources on places where the tangible benefits to human rights are greatest. Success will require setting priorities as well as engaging local stakeholders such as nongovernmental organizations and national human rights institutions. To date, promoters of international human rights law have relied too heavily on setting universal goals and procedures and not enough on assessing what actually works and setting priorities. This book illustrates how, with a different strategy, human rights stewards can make international law more effective and also safeguard human rights for more of the world population.

The Status

Almost 50 per cent of the world population is constituted by the women and they have been making substantial contribution to socio-economic development. But, unfortunately their tremendous contribution remains unrecognized and unnoticed in most of the developing and least developed countries causing the problem of poverty among them. Empowering women has become the key element in the development of an economy. With women moving forward, the family moves, the village moves and the nation moves. Hence, improving the status of women by way of their economic empowerment is highly called for. Entrepreneurship is a key tool for the economic empowerment of women around the world for alleviating poverty. Entrepreneurship is now widely recognized as a tool of economic development in India also. In this paper I have tried to discuss the reasons and role of Women Entrepreneurship with the help of Push and Pull factors. In the last I have also discussed the problems and the road map of Women Entrepreneurs development in India.

The Relationship

Research on the relationship between fertility and gender ideology revealed inconsistent results. In the present study, we argue that inconsistencies may be due to the fact that such relationship may be nonlinear. We hypothesize a U- shaped relationship between two dimensions of gender ideology (i.e. primacy of breadwinner role and acceptance of male privilege) and fertility rates. We conducted a cross-national analysis of 60 countries using data from the World Values Survey as well as the World Population Prospects 2019. Controlling for gross domestic product, we found support for a U-shaped relationship between gender ideology and fertility. Higher levels of fertility rates were found at lower and especially higher levels of traditional gender ideology, while a medium level of gender ideology was associated with the lowest fertility rate. This curvilinear relationship is in agreement with the phase of the gender revolution in which the country is located. Traditional beliefs are linked to a complementary division of private versus public sphere between sexes, while egalitarian attitudes are associated with a more equitable division. Both conditions strengthen fertility. Instead, as in the transition phase, intermediate levels of gender ideology’s support are associated with an overload and a difficult reconciliation of the roles that women have to embody (i.e. working and nurturing) so reducing fertility. The present study has contributed to the literature by addressing the inconsistencies of prior research by demonstrating that the relationship between gender ideology and fertility rates is curvilinear rather than linear.
