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.

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.

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.

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.

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.

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.

Aminopyrine (AM) has been used as a model substrate for investigation of drug metabolism. The major metabolic route is N-demethylation that was confirmed in liver microsomes. The aim of the present study was to identify the human cytochrome P-450 enzyme (CYP) mediating the N-demethylation of 4-di-methylaminoantipyrine (4-DMAA) to 4-methylaminoantipyrine (4-MAA). The contribution of human CYP to the metabolism of (4-DMAA) to (4-MAA) in human was investigated using virus expressed human CYP, human liver microsomes with chemical inhibition studies. The substrate of 4-dimethylaminantipyrine was employed at different concentrations (11.5, 23, 46, 115 and 230 µmol per l) with varying concentrations of selective inhibitors of CYP (CYP1A2), (CYP3A4), (CYP2C8),(CYP2A6), (CYP2D6), (CYP2C19) and (CYP1A1). 4-DMAA and 4-MAA were analysed by HPLC and enzyme kinetic parameters (Km and Vmax) were calculated from the concentration data. The transformation of 4-dimethylaminoantipyrine to 4-methyaminoantipyrine by microsomes prepared from baculovirus-expressed human CYP was pronounced with CYP2D6. The metabolism of 4-dimethylaminoantipyrine was inhibited by 60.0% and 55.17% by a concentration of 100 µmo per l of the known CYP2D6 inhibitors quinidine and moclobemide. The corresponding Ki values were 0.050 and 0.11 mM, respectively. The corresponding IC50 values were 0.06 and 0.13 mM, respectively. The enzyme CYP2D6 apparently has an important role in N-demethyl-ation of 4-dimethylaminoantipyrine.

Metamizole or Novalgin® is a widely used well tolerated analgesic drug which is however compromised by agranulocytosis as adverse effect. Subsequent to nonenzymatic hydrolysis, the primary metabolic step is N-demethylation of 4-methylaminoantipyrine (4-MAA) to 4-aminoantipyrine (4-AA). The aim of the present study was to identify the human cytochrome P-450 enzyme (CYP) mediating this reaction. This study identified the relevant CYP using virus expressed isolated human CYP, human liver microsomes and rat liver microsomes with chemical inhibition studies. The substrate of 4-methylaminantipyrine was employed at six different concentrations (25, 50, 100, 400, 800 and 1200 µmol per l) with varying concentrations of selective inhibitors of CYP1A2 (furafylline, fluvoxamine), CYP3A4 (ketoconazole), CYP2A6 (coumarin), CYP2D6 (quinidine), CYP2C19 (omeprazole, fluvoxamine, tranylcypromine), CYP2C9 (sulphaphenazole) and CYP1A1 (alpha-naphthoflavone). 4-MAA and 4-AA were analyzed by HPLC and enzyme kinetic parameters (Km and Vmax) were determined by regression (Sigma plot 9.0). The N-demethylation of 4-MAA by microsomes prepared from baculovirus expressing human CYP was pronounced with CYP2C19. Intrinsic clearance of the most active enzymes were 0.092, 0.027 and 0.026 for the CYP enzymes 2C19, 2D6 and 1A2, respectively. Metabolism by human liver microsomes was strongly inhibited by fluvoxamin, omeprazole and tranylcypromine (IC50 of 0.07, 0.07 and 0.18, respectively) but with coumarin, sulphaphenazole, ketoconazole, moclobemid, quinidine alpha-naphthoflavone and furafylline were 0.79, 1.20, 1.36, 1.44, 3.46, 4.68 and 8.41, respectively. The enzyme CYP2C19 apparently has an important role in N-demethylation of 4-methylaminoantipyrine which should be further analyzed in clinical studies and which may also be interesting concerning the agranulocytosis.

Background: Many individuals today use herbs as a drug alongside medicine and non-physician-recommended medications, as herbs are thought to be natural and safe. However, many herbs can potentially interact with other drugs, causing hazardous effects and diminished therapeutic effects of different prescriptions. Objective: It ought to be comprehended that herbal drugs contain multiple active compounds in different percentages, which can change the enzymatic frameworks, transporters, and physiological processes. Methods: Data on pharmacokinetic drug interactions with herbal products were searched using different search engines, such as Google Scholar, Scopus, and ScienceDirect. Results: This worldwide increment in herbal drug popularity has risen concerning HDIs. These PD or PK interactions are particularly significant for medications. Assessment of herbal drug interactions is complex because of inconsistency in herbal drug composition and frequently meagre information on active constituent pharmacokinetics. These restrictions are further bewildered by the differing points of view concerning herbal product regulation. Conclusion: It is concluded that a basic assessment of certain pharmacokinetic HDI is needed to settle on educated choices regarding patient safety. The expanding comprehension of HDPKI will direct more attention to potential interactions.

Introduction: Study was conducted with an objective of investigating the inhibitory effect of Phaseolus lunatus seeds extract on three enzymes (α-amylase, maltase and glucoamylase) involved in diabetes. The disadvantages related to the use of synthetic drugs make it necessary to search for alternative medicines from medicinal plants. One therapeutic approach for treating postprandial hyperglycaemia is to decrease the plasma glucose level, which can be attained by lowering the starch hydrolysis by digestive enzymes such as α-amylase, maltase and glucoamylase. The use of synthetic antidiabetic agents caused gastrointestinal side effects. Methods: Hence, the research was aimed to evaluate the potential of Phaseolus lunatus seeds extract to inhibit α-amylase, maltase and glucoamylase as a possible mechanism of hypoglycemia caused by this plant with fewer side effects. Phaseolus lunatus, also known as Lima bean, is native to Tropical America and grown worldwide. Lima bean has been prescribed traditionally to treat different diseases, including diabetes. Result: The results of the present study showed that Phaseolus lunatus seeds extract has exerted both time and concentration-dependent Significant inhibitory effects on these digestive enzymes might be due to the cumulative impact of phytoconstituents in the plant extract. Conclusion: Therefore, it can be said that the part mechanisms by which Phaseolus lunatus exhibited its antidiabetic activity might be through inhibiting this digestive enzyme.
