Medicinal use of strongly toxic aconitum napellus l.

Here is presented a short review on the medical potency of the most toxic plant of Europe. In many countries it isn't concerned any more as therapeutic agent in medicine due to frequent intoxications. However, in the homeopathy, preparations and patent medicines still contain aconitine and other alkaloids (abundant levels). There exists even a US Patent "ACONITINE COMPOUNDS, COMPOSITIONS, USES, AND PREPARATION THEREOF" (No. US 9,085,536 B2 by du Bois et al. 2015).

A comparative study of social and economic aspect of migration

India is a country of immense diversity. It is home to people of many different racial, languages, ethnic, religious, and national backgrounds. Groups of people in India differ from each other not only in physical or demographic characteristics but also in distinctive patterns of behavior and these patterns are determined by social and cultural factors like language, region, religion, and caste. Apart from behaviour, economic development, level of education and political culture of the people in various social segments differ from region to region. More you can say that economy and cultures have been enriched by the contributions of migrants from round the globe. In an increasingly globalised world, migratory movements is continuously shaping the countries all over the world. Some countries like India and Ireland, which set the example of economic development and social integration, have the positive impact of the migration by globalisation and some countries like USA, which recently witness racism, xenophobia and discrimination have the negative impact on the migrants. It does not mean India do not face fragmentation and USA do not have cohesion. USA have many stories which show successful integration process, that facilitated the lives of immigrant communities, but being a developed country it still suffers from cultural alienation. In these countries, borders are built within borders to create cultural divides that do not allow people to integrate. Recently, this problem has become more prominent due to the rise of terrorism, clash of cultures in the world, leading to the glorification of stereotypes. People are becoming less accepting towards anyone who does not belong to their region. Migration does not stop after people move from one place to another place. The main question start after that ‘now what’ they will do. That is why this topic needs to be discussed thoroughly in order to find better solutions. This paper will begin with an analysis of different approaches to Migration, discuss the target groups for integration policies, provide indicators of the current situation of migrants and proceed to an analysis of integration tools: legislation, social policies and participatory processes. It will focus not only on the impact of migration but also on social integration, mix culture like indo-western culture in a comparative basis.

Study of temperature variation in human peripheral region during wound healing process due to plastic surgery

In this paper, investigations are made to analyze the human body temperature during wound healing process due to surgery. Wound is considered after the skin graft. Skin graft is a technique used in plastic surgery. Skin is the first line of defense between the human and environment, it is very susceptible to damage. Internal body or core temperature (Tb) is one of the clinical vital signs along with pulse and respiratory rates. Any disturbance in body temperature will drive complexities in wound healing process. These studies are important in the mechanism of establishing the limits of thermal regulation of human body during the healing process in different situations and conditions. The Finite element method is used to analyze tissues temperature for normal tissues (donor site) and abnormal tissues (tissues after surgery). Appropriate boundary conditions have been framed. Numerical results are obtained using Crank Nicolson Method.

Metapuf: a challenge response pair generator

Physically unclonable function (PUF) is a hardware security module preferred for hardware feature based random number and secret key generation. Security of a cryptographic system relies on the quality of the challenge-response pair, it is necessary that the key generation mechanism must unpredictable and its response should constant under different operating condition. Metastable state in CMOS latch is undesirable since it response becomes unpredictable, this feature used in this work to generate a unique response. A feedback mechanism is developed which forces the latch into the metastable region; after metastable state, latch settle to high or state depends on circuit internal condition and noise which cannot be predicted. Obtained inter hamming variation for 8 PUF is 51% and average intra hamming distance is 99.76% with supply voltage variation and 96.22% with temperature variation.

Intersection of caste and gender based subjugation

One of the unique features of Indian society is prevalence of caste system which was originated thousands of years back to demarcate the people engaged in different occupation or jobs. Initially it was not much rigid but gradually people belonging to upper castes for their own selfish means to maintain their monopoly made this arrangement hereditary and started treating people of lower castes disgracefully. For preservation of this system, people started controlling their women to prevent inter-caste marriages and the concept of endogamy came up. This robbed away many types of freedom from women. For women belonging to lower castes, this situation is worse as they are doubly subjugated on the basis on caste as well as gender. Men belonging to their own caste treat them as secondary beings. This paper throws light on this intersection. How intersection of these two kinds of inequalities place them at the lowest position in Indian society. Dr. B.R. Ambedkar rises as their leader who all his life worked for empowerment of downtrodden section of society. He argues that education is the primary tool for evading these differences among people. He further emphasizes to adopt the concept of exogamy to break the backbone of Indian caste system and to immediately leave a religion or culture which legitimizes such system of inequality among people of the same land.

A comprehensive study of gorvara puta in preparation of rasa bhasma

Ayurvedic formulations are of three types, Herbal, Mineral and Herbo-Mineral. Of which, Herbomineral is prepared either by Khalweeya or by Bhasmeekarana procedures. The quality of Bhasma depends on the number of putas given. Rasa Bhasma is one such kind of a Herbo-mineral preparation which can be obtained by Puta procedure as described in texts of Rasa Shastra. Though there are different procedures mentioned for preparation of Rasa Bhasma, maarana done with Gorvara puta seems to be an apt way to obtain the final product. Puta is the generalised way of heat application used during the pharmaceutical procedures of Rasa dravyas, where the purified organic Metal/Mineral is converted completely into powder form which can be absorbed easily into the body without causing any ill effects. Different types of Puta have been explained for bhasmeekarana of different metals and minerals. Among them, certain putas have been mentioned where Mandaagni plays a crucial role in Maarana (Incineration). These Mandaagniputas are in use of preparing certain Bhasmas like ShilajitBhasma, HaratalaBhasma, GouripashanaBhasma, and PaaradaBhasma. As these drugs are having relatively low boiling and melting points when compared to other dravyas, and are easy to evaporate when exposed to high temperatures, they need a standardized quantum of heat by which they can be transformed into Bhasma. Gorvara puta is one such kind where agni plays a major role in the preparation of Bhasma. So, the present study A Comprehensive Study of Gorvara Puta in Preparation of Rasa Bhasmahas has been under taken.

A critical review on mode of action of ayurvedic formulations on jwara

Rasa aushadhis are known for their uniqueness in curing the diseases with a very low dosage. These formulations are divided into two types based on their mode of preparation i.e., Single drug and Compound drug formulations. Based on their origin, the drugs are divided into three types, Herbal, Mineral and Animal. Any of these two or three together is combined to make a compound formulation. Apart from these, the other major factor which is needed for a formulation is the Rasa Panchaka of a Drug. Many of the formulations are being prepared based on their availability, keeping their Rasa Panchaka and Samprapti vighatana in mind. These formulations are designed in such a way that two or more drugs will be having one common quality, or Opposite Qualities or an Antidote of a particular Vishadravya, which can help in curing the disease. So an attempt is made to Review Tribhuvanakeerti Rasa with its Probable mode of action.

Phytochemical screening and structure elucidation of isolated compounds from convolvulus dorycnium plant originated from west of libya

Plants are an ancient source of medicine due to the presence of bioactive molecules of various compounds in their different parts. Convolvulus dorycnium plant belongs to the family of wind plants (convolvulaceae). The greatest variety of Convolvulus plants are broadly distributed over the world and was found in Western and Central Asia, Mediterranean, Macaronesia, East Africa, and Arabia. The plant C. dorycnium was collected from Tarhuna in Sidi Said area of Libya in May 2013. Plants belonging to Convolvulus genus contain various phytochemicals profiles. The focus of this study is on the phytochemical analysis of convolvulus dorycnium including phytochemical screening, extraction, isolation, and characterization. The phytochemical screening reveals the presence of flavonoids, tannins, saponins, steroids, carbohydrate, and coumarin in ethyl acetate and methanolic extract. Column chromatography and column chromatography and TLC were used to fractionate the ethyl acetate extract and H-NMR was used to elucidate the isolated compounds. Some compounds were isolated from the aerial parts of the plant; scopoletin, which is a phenolic coumarin (1) (7-hydroxy-6-methoxy coumarin), caffeic acid (2) (3,4-dihydroxycinnamic acid), and ferulic acid (3) (4-hydroxy-3-methoxy cinnamic acid) which are phenolic acids. The chemical constituents present in the extract have been reported to possess many biological activities

Medicinal plants with non-steroidal anti-inflammatory-like activity

Inflammation is a natural aspect of the immune system's response. Pain, redness, heat or warmth, and swelling are the four major symptoms of inflammation. Plants can generate a vast range of phytochemical substances as secondary metabolites, all of which have anti-inflammatory properties. Herbal medicines are significant cures for the treatment of a variety of disorders around the world. Medicinal plants are made up of roughly 7500 species, with representatives from about 17,000 higher flowering plant species. Even when synthetic chemistry has advanced beyond expectations, the utilization of natural products in the production of medications utilized in modern medicine is unrivalled. Anti-inflammatory medicines can help to reduce tissue damage and improve patient comfort by interfering with the pathophysiology of inflammation. As a result of the huge number of species available for investigation, the effective creation of new naturally occurring anti-inflammatory medications relies mostly on a multidisciplinary approach to finding new compounds. Despite the fact that many review articles have been written in this area, the vast majority of them only looked at the subject from a regional perspective. Various non-steroidal anti-inflammatory medicines have been proven to alleviate pain and inflammation by inhibiting the isoform of cyclooxygenase enzyme's digestion of arachidonic acid, hence lowering prostaglandin synthesis. Non-steroidal anti-inflammatory medicines come with a slew of negative side effects. Thus, there are, however, medicinal herbs that have anti-inflammatory therapeutic properties with a little or no negative side effects.

Phytochemical constituent, cytotoxic activity and outcome on wheat growth parameters possessed by extracts of seaweed collected from libyan coast

Algae are used by human beings for food from ancient times, as they contain a wide range of elements. Using inexpensive, in-house bioassays for screening and monitoring of extracts where the aim of these bioassays is to provide a front-line screen that can be followed up by more specific and expensive bioassays. The phytochemical screening, assessment of toxicity and effects on growth parameters of Traticum sativum of ethanol and dichloromethane extracts of five macro-algal species (two green, two brown and one red) collected from Libyan coast were studied. The Brine shrimp lethality assay was conducted to determine the toxic effects of seaweed extracts on Artemia Salina nauplii larvae and this was to provide a front-line screen that can be backed up by specific and expensive bioassays once the active compounds have been isolated. The effect of seaweeds liquid fertilizer on growth parameters of Traticum sativum were examined using in vitro seed germination in petri dishes bioassay. Seed germination percentage, fresh and dry weight, shoots length and roots length were the parameters recorded in young seedlings post germination. Ethanolic and dichloromethane extracts of the five algae samples represented the presence of several chemical constituents. All extracts exhibited LC50 > 1000 μg per ml. In this study, all algal extracts are non-toxic according to Brine shrimp lethality assay so they may be considered as edible seaweeds. Different effects on growth parameters of Traticum sativum suggested the presence of micro-elements, macro-elements and different concentrations of plant growth hormones.
