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.

Mosquitoes conveying Plasmodium store parasites into the skin of the mammalian host. Parasites make a trip through the circulation system to the liver, where they cross a few hepatocytes prior to building up a disease. Inside the last hepatocyte the parasite goes through morphogenesis and afterward abiogenetically partitions to become more than 20,000 blood-infective parasites, called merozoites. On account of P. vivax, P. ovale, and P. cynomolgi, the parasites can stay lethargic in the liver in structures called hypnozoites. The merozoites are delivered once again into the circulation system, where they start the repetitive blood stage. Inside erythrocytes, a little division of parasites separate into male or female gametocytes. These gametocytes are ingested by the mosquito during blood taking care of, where they will duplicate explicitly, in the long run prompting the arrangement of sporozoites

Oxidative stress is due to altered levels of prooxidants and anti-oxidants in the body. This can lead to tissue damage especially the central nervous system. Oxidative damage has been implicated in several disorders including some psychiatric disorders such as schizophrenia and major depressive disorder. Uric acid is an anti-oxidant which prevents tissue damage caused by oxidative stress. In this review, the reduced levels of serum uric acid in schizophrenia and depression are discussed. The effect of treatment in these disorders leading to increased serum uric acid levels are also reviewed.

Prevalence of hypovitaminosis D is not restricted to the elderly and hospitalized population. Worldwide, the rate of prevalence of vitamin D deficiency has grown up rapidly in adults over the past decades. Among Libyan population including young students may has a high risk of vitamin D deficiency. The aims of this study were to examine vitamin D status among pharmacy students of Sebha University and to study the hematological profile as well as correlation of vitamin D deficiency with incidence of anemia among the students. This study was carried out on Pharmacy students from 13th January to 12th March, 2020. This is a cross-sectional study designed to determine vitamin D status among healthy young pharmacy students studying at the Sebha University. The blood samples were collected randomly from 62 pharmacy students to analysis complete blood count and 25-hydroxyvitamin D. The concentration of hemoglobin on total student was 12.5 ± 1.9 g/dl which was normal according to the WHO level (12.0 g/dl). Out of total, 36 students (59.1%) were found to have normal hemoglobin concentration (13.7 ± 1.4 g/dl) and 26 students (40.9 %) were found to have low hemoglobin concentration (10.8 ± 1.1 g/dl). Other blood profile as HCT, MCV, MHC and MCHC where statistically significant lower but the counts of RBCs, WBC and platelets were not on anemic group comparing to normal group. The present study reported that majority of pharmacy students in male and female blood donors have low vitamin D levels which represent (87.0%). Out of the total participants (n = 54) who have low vitamin D (n = 49, 79.0%) were classified under vitamin D deficiency category while (n = 05, 08.0%) of students had vitamin D insufficiency. In conclusion, prevalence of hypovitaminosis D (low 25-hydroxyvitamin D) among the pharmacy students at Sebha University was highly occurrence with concomitant a high rate of prevalence of anemia. Thus, vitamin D deficiency at this age represents a public health problem that should be addressed.

In the present study the effect of the ethanol extract of Culcasia falcifolia on the neurotransmitter levels were evaluated. Pentylenetetrazole (PTZ) (60 mg/kg body weight, i. p) was administered to all the groups of mice to induce convulsions. After observing the convulsion, all groups rats were sacrificed, whole brain was dissected out and separated the forebrain. The brain tissue was homogenized and then centrifuged. The aqueous phase was taken for the assay. The reading was obtained using spectroflurimeter. The result of the present study shows that the ethanol extract of Culcasia falcifolia at the dose of 200 and 400 mg/kg body weight significantly increased the level of inhibitory neurotransmitter GABA and also showed significant increase in the levels of dopamine, noradrenalin and serotonin when compared to seizure control group (PTZ treated group) and was almost equivalent to control group. The findings of the study showed that the extract at 200 and 400 mg/kg body weight significantly (p<0.001) increased the levels of GABA, dopamine, serotonin and noradrenaline. The ethanol extract of Culcasia falcifolia exerted antiepileptic activity by decreasing seizure susceptibility to pentylenetetrazole-induced seizure in mice due to restoration of GABA, serotonin, dopamine and noradrenaline concentration levels in mice brain.

Abstract In the existing investigation, experiments were carried out to assess the F2 population’s resultant of crosses between improved Basmati 370 and MAS25 for various agronomical and root traits cultivated under aerobic water conditions. Large variations for grain yield, root length, root dry biomass, root thickness and length/breadth ratio of grain have been displayed in segregating F2 populations. A close examination of phenotypic correlation exhibited that in the F2 population, root length was certainly matched up (r = 0.496) with root thickness. A DNA fingerprinting catalog for the currently studied F2 generation was arranged using 61 polymorphic SSR markers. Composite Interval Mapping (CIM) inspection with WinQTL cartographer version 2.5 disclosed 13 putative QTL (Quantitative Trait Loci), out of which 6 QTL were for root characters 7 QTL for agronomical characters situated on 1, 2, 3, 8 and 10 chromosomes. The QTL documented in the above-said generation, some promising F2 plants were also scrutinized and found in the homozygous or heterozygous state with high repetitions.

The space-time dynamics of chlorophyll a concentration and seawater excess viscosity has been investigated in the hydrographically contrasting inshore and offshore water masses of the eastern English Channel. This was done during the phytoplankton spring bloom dominated by Phaeocystis globosa before and after the very large-scale formation of foam induced by an increase in wind-driven turbulence and the related wave breakings. The results suggest that the dynamics of chlorophyll a concentration and seawater excess viscosity are differentially controlled by the formation of foam through the intensity of the spring bloom and wind-generated turbulence.

This study examines the first occurrence of non-toxic dinoflagellate blooming of Gonyaulax polygramma and Chaetoceros sp in Ambon Bay that occurred for almost three weeks in January 2019 and it caused the watercolor became red brown. The objective of this study was to identified phytoplankton species and their abundance that cause red tide in the Inner Ambon bay. Phytoplankton samples were collected, temperature, salinity and Secchi depth were measured simultaneously on the 11th and 21st January 2019 (nortwest monsoon) at fifteen sampling stations in Inner Ambon Bay. The results show that the maximum abundance of G. polygramma, Chaetoceros affinis, C. danicus and C. decipiens were found in the greatest concentration up to 20×109, 9.0x106, 5.8x106 and 3.8x105 cells.L-1, respectively. They were found either in the form of a single cell or in chains. The very high abundance of cells of those species made the waters become red brown but there was no reports of fish killed during this red tide phenomena. This is the first time report of blooming phytoplankton Gonyaulax polygramma, Chaetoceros affinis, C. danicus and C. decipiens occurred in Ambon bay during the dry season where the recorded waters temperature and salinity ranged from 30-32ºC and 29-33 psu, respectively and the secchi depths ranged from 2 to 6m. These results show this is the first report of the red tide phenomena in the Inner Ambon bay during the dry season and it occurred for a long period caused by combination of the high abundance of G. polygramma Stein, Chaetoceros affinis, C. danicus and C. decipiens.

Biological information processing networks rely on allosteric protein switches that dynamically interconvert biological signals. Construction of their artificial analogues is a central goal of synthetic biology and bioengineering. Receptor domain insertion is one of the leading methods for constructing chimeric protein switches. Here we present an in vitro expression-based platform for the analysis of chimeric protein libraries for which traditional cell survival or cytometric high throughput assays are not applicable. We utilise this platform to screen a focused library of chimeras between PQQ-glucose dehydrogenase and calmodulin. Using this approach, we identified 50 chimeras (approximately 23% of the library) that were activated by calmodulin-binding peptides. We analysed performance parameters of the active chimeras and demonstrated that their dynamic range and response times are anticorrelated, pointing to the existence of an inherent thermodynamic trade-off. We show that the structure of the ligand peptide affects both the response and activation kinetics of the biosensors suggesting that the structure of a ligand:receptor complex can influence the chimera's activation pathway. In order to understand the extent of structural changes in the reporter protein induced by the receptor domains, we have analysed one of the chimeric molecules by CD spectroscopy and hydrogen-deuterium exchange mass spectrometry. We concluded that subtle ligand-induced changes in the receptor domain propagated into the GDH domain and affected residues important for substrate and cofactor binding. Finally, we used one of the identified chimeras to construct a two-component rapamycin biosensor and demonstrated that core switch optimisation translated into improved biosensor performance.

Transglutaminase 2 (TG2) is an inducible transamidating acyltransferase that catalyzes Ca2+-dependent protein modifications. TG2 enzyme disruption has been implicated in several different disease processes and disorders such as Huntington and Parkinson’s diseases, cancers such as breast, ovarian and pancreatic cancers. Coeliac disease (CD) is the one disease state that TG2 activity plays a crucial role. To date, a gluten-free diet is the only accepted form of therapy for CD. Because of the important role of TG2 enzyme in the initiation of CD, therefore, this study was aimed at the identification of TG2 inhibitors from natural sources, as a potential intervention in CD therapy. Competitive amine inhibitors are the most widely used TG2 inhibitors because they are commercially available, chemically stable and relatively non-toxic in living systems. The natural products chosen for this study were dietary flavonoids. Flavonoids were extracted from different food samples. The flavonoids food extracts were subjected to the TG2 activity assays to examine their effect on the enzyme activity. The assays were carried out under optimal conditions of pH, Ca2+ and with N, N-dimethylcasein (acyl-donor) or casein (acyl-acceptor) as acyl-donor substrates and biotin cadaverine (acyl-acceptor) or TVQQEL as (acyl-donor) substrates. TG activity was measured by two different microplate assays, Biotin-labeled cadaverine incorporation assay and Biotin-labeled peptide cross-linking assay. In the TG2 amine incorporation activity, all of food extracts display a significant inhibition effect towards the human recombinant transglutaminase2 (hrTG2) and guinea pig transglutaminase 2 (gplTG2) (20 - 50% of inhibition). While in the TG2 cross-linking activity, the majority of food extracts displayed an inhibition effect on the gplTG2 cross-linking activity (50 - 70% of inhibition) but only the strawberry and kale extracts showed an effect on hrTG2 activity (40 - 50% of inhibition). The inhibition of TG2 activity can be considered as a potential therapeutic target in the treatment of CD.

Tobacco smoking negatively affects the quality of saliva and affects many biological parameters including salivary α-amylase enzyme activity. Salivary α-amylase enzyme is essential for the catabolism of carbohydrates. Forty- five healthy male volunteers aged between 18 and 69 years (40.0 ± 15.0) were divided into two groups, namely, the control group (n = 21) and the cigarette smoker group (n = 24). The effect of smoking on salivary α-amylase enzyme activity depends on the number of smoked cigarettes per day and the type of cigarettes as well as the period for how long the person smoking tobacco cigarettes was investigated. Different methods were used to analyze the activity of salivary α-amylase enzyme including the dinitrosalicylic acid method (standard colorimetric method). The results showed a significant increase (P < 0.05) in salivary α-amylase activity in Libyan smokers compared to the non-smokers in the morning and night, also, the findings showed a significant decline in salivary α-amylase activity during the increasing smoking period. The activity of salivary α-amylase in the young age smokers group increases in morning and night compared to the non-smokers group. There is no change in the activity of salivary α-amylase in the middle and older adult groups in the morning and night compared to young smokers group. In conclusion, smoking for a long period time more than 20 cigarettes per day decreases the activity of salivary α-amylase in Libyan subjects.

Uric acid has increasingly been associated with insulin resistance, hyperinsulinemia, and type 2 diabetes mellitus. Diabetic patients who are hyperuricemic have a risk of developing diabetic complications. Pathogenesis of uric acid may decrease nitric oxide bioavailability in vascular smooth muscle, endothelial cells and direct scavenging of nitric oxide by uric acid. A decrease in endothelial nitric oxide production by uric acid has also been associated with endothelial dysfunction and insulin resistance. This study aims is to determine the relationship between uric acid and glucose levels in patients with type 2 diabetes mellitus. The study included 161 Libyan patients (67 males and 94 females) diagnosed with type 2 diabetes mellitus. Both levels of serum uric acid and hemoglobin A1c (HbA1c) were determined. The patients were divided into two groups. The controllable diabetic group with HbA1c of less than 06.0% and the uncontrollable diabetic group with HbA1c of more than 06.0%. Patients who are suffering from type 2 diabetes mellitus without complications were included whereas patients with smoking, alcoholism, nephrotic disease, malignancy, hepatitis, and renal failure or kidney disease were excluded. The mean and standard deviation of uric acid, HbA1c and Pearson correlation coefficient test were considered. In the controllable diabetic group, serum uric acid mean was found to be 4.807 ± 1.39 and HbA1c was found to be 5.032 ± 1.39. In the uncontrollable diabetic group, serum uric acid was 4.897 ± 1.66 and HbA1c was 8.396 ± 1.65. Uric acid level has significantly been correlated with HBA1C in controlled and uncontrolled diabetic patients (p < 0.05). In addition, the uric acid level was found to be higher in uncontrolled diabetic group than that in the controlled group (p < 0.05). A possible relationship between serum uric acid and incidence of type 2 diabetes mellitus was noted. Thus, uric acid can be used as a potential biomarker to indicate impaired glucose metabolism.

The incidence of diabetes mellitus has increased globally making it a major public health concern. Diabetes mellitus is the most common metabolic disorder that causes an imbalance in the electrolytes which regulate essential metabolic mechanisms of the body. This study aimed to estimate the electrolyte levels in Libyan patients with type II diabetes mellitus and to investigate their relations to glycemic control and body mass index. A total of 122 Libyan subjects whose ages ranged between 35 years and 60 years for both sexes were included in this study, 77 patients were type II diabetic patients (37 males and 40 females) and 45 subjects were healthy individuals (23 males and 22 females) live in Tripoli area, Libya. The levels of blood glucose, HbA1c, sodium, potassium, chloride, magnesium and calcium were estimated in this study along with the measurement of body mass index, systolic and diastolic blood pressure. All the findings were statistically analyzed by one-way ANOVA test. Significant increases in glucose, HbA1c, potassium, chloride, calcium, blood pressure and BMI among diabetic patients were observed as compared to the healthy individuals. On the other hand, significant decreases in sodium and magnesium levels among the diabetic patients were observed as compared to the control group. In addition, significant alterations in all the biochemical parameters in uncontrolled diabetic patients as compared to the controlled diabetic patients, and in unhealthy weight diabetic patients as compared to the healthy weight patients. It is concluded that diabetes mellitus results in an imbalance of electrolytes. Poor glycemic control and obesity have adverse effects on electrolyte balance among diabetic Libyan patients. Good glycemic control, maintaining a healthy weight and regular evaluation of electrolytes among diabetics can reduce the fatalities associated with electrolyte rearrangements.
