According to various reports, allospecific T cell stimulation is a requisite for elimination. Nevertheless, the method of allospecific T cell stimulation is mostly convenient along with recent agents. Appropriately, brief consequences in allotransplantation possess a consistently upgrade demonstration toward the particular consequence of the T cell-centric sight of contemporary remedy. Thus, the area of awareness has twisted about fall behind the lengthy result. Unchangeable chronic graft devastation to pursue to represent clinical transplantation proposes at that place are main features of alloimmunity those are un-mollified by uncomplicated T cell-directed immunosuppression. As a matter of fact, in the previous generations, it has been evident that the comprehensive biological circumstances jointly recorded as non-acceptance included nearly the Gordian web of elements, both provocative and managerial, that form the makeup of allorecognition. T cell responses, counting the T cell reliant allograft response, are circumstantially determined by the condition of innate immunity in that T cells associated with antigen. Organs used for transplantation exist commonly of deceased donors, for the past two generations are obtained by surgical procedure and then positioned into icy protection mixture prior section implantation into the receiver. Brain death, ischemia-reperfusion, hypoxia, and hemostasis-linked injuries significantly command the condition of innate immunity inside the transplant. Normally, each one of these procedures stimulates innate immunity into a pro-inflammatory shape that develops tissue critical forms of adaptive immunity. These pathways and cell types turned out to port mainly untargeted, or at minimal under close, and these points of removal facilitate the center of this matter.

Nigella sativa is famous for its usefulness in a wide range of diseases and disorders since ancient times. Numerous plant-derived products play an important role in promoting cardiac health. N. sativa is the name of a plant whose seeds are well known for their medicinal uses in many Middle East, Asian, and far Eastern countries. These plants are mainly found in North Africa, Indian subcontinent and Western Asia (Eric Y. and Kathy A., 2014). N. sativa is the part of kingdom Plantae and family of flowering plants known as Ranunculaceae. It is also known by many names such as black seed or kalonji. This plant has many active ingredients such as amino acids, proteins, carbohydrates, and some volatile oils (Fatemah et al., 2014). Among these, thymoquinone (TQ) is one of the active ingredients of N. sativa (Oskouei et al., 2018). It is well known for its usefulness in cardiovascular diseases (CVDs). CVDs form the single largest cause of early mortality in developed as well as developing countries at an alarming rate. TQ and N. sativa as a whole have a protective role on a wide range of metabolic and cardiac diseases. This is mainly due to its rich flavonoid and antioxidant content. A balance between free radical injury and antioxidant intake helps our body's defense mechanism to overcome different forms of oxidative stress. TQ may prove as a useful substance that may help in improvement of biochemical imbalances in human body. It has been observed in different studies that TQ efficiently improved CVD by declining β-hydroxy β-methylglutaryl coenzyme A (HMG-CoA) reductase activity and hence lowering the total cholesterol levels. Studies have shown that TQ decreases mean arterial blood pressure and heart rate in hypertensive rats. Biochemically, fatty acids like linoleic acid, oleic acid, palmitic acid have been found in N. sativa derivatives. Various aromatic constituents such as TQ, dihydrothymoquinone, thymol, carvacrol, and different alkaloids are also present in N. Sativa. Antioxidant properties of its various components make it a useful substance. The main precursor for build-up of oxidative stress is reactive oxygen species (ROS) formation in excess amounts. This is due to oxidation of various biomolecules and adds on to the vascular changes in the heart and damage to vessels. TQ is well known for its role in CVDs. Various studies have shown that TQ promotes and boosts heart health. Antioxidant defense mechanisms of our body fail to balance this surplus ROS production; hence, produce oxidative stress. Oxidative stress is the major culprit for various metabolic disorders like CVDs, systemic hypertension, diabetes mellitus, etc. In this chapter, we have discussed how N. Sativa intake can help in prevention of cardiovascular disorders that is becoming a major cause of mortality and morbidity worldwide.

Micro-RNAs are important group regulators of gene expression that play a key role in a range of biological processes including cell proliferation, differentiation, and development as well as apoptosis. Moreover, micro-RNAs are emerging as critical regulators of inborn and acquired immune responses. The aberrant expression or activity of the micro-RNAs in the immune system has been related to many human ailments such as inflammatory diseases including cancer and inflammatory bowel disease. Gene defects have a variety of effects on the immune system, ranging from restricting or preventing the production of new immune cells to mutations that impair immune cell functions, some of which contribute to increased susceptibility to specific species. In this chapter we have reviewed the genetics basis of immune responses and the potential role of micro-RNAs in immune regulation and dysregulation.

COVID-19 also called corona virus emerged in China in December 2019. This turned into a global pandemic in a short period of time. Covid-19 is a novel strain of corona virus that was not seen earlier in human beings. It is important to study the molecular structure of Covid-19 so as to aid in the development of therapeutic measures. Existing Covid-19 pandemic poses an extraordinary risk to health and healthcare systems worldwide. Corona viruses are made of single stranded RNA present within the coat proteins. The virus has a diameter of nearly 80–120nm. Usually, Covid-19 presents with the signs and symptoms of respiratory illness. Cough commonly dry cough, fever, associated with myalgias and sometimes breathing difficulties due to decrease in oxygen saturation rates are also present in these patients. Some people show fever with body aches, while some are relatively asymptomatic. Corona virus is primarily transmitted in humans through respiratory route and is highly contagious. Mostly old people and those having comorbid illnesses suffer most. After invading into the human body, the virus may lead to a sequence of processes such as viral invasion, replication, and programmed cell death, that is, apoptosis. To control and prevent this viral infection, we need to study the molecular aspects of Covid-19 in detail so as to design therapeutic agents as well as for vaccine formation. The micro-RNA is defined as the single-stranded noncoding RNA molecule. They have a length of about 22 nucleotides approximately and help in the post transcriptional regulation of gene expression. Micro RNAs regulate many types of cancers in addition to Covid-19 and other infections. Viral micro RNA is a newer type of mi-RNA and controls the host cell expression and viral target genes. This was completed by inducing micro-RNA cleavage, breakdown, translation, inhibition, or other mechanisms. The micro-RNAs of Covid-19 are explained to give an authoritative means to study this novel coronavirus. These control the host cell expression and also viral target genes by inducing micro-RNA cleavage, breakdown, translation, inhibition, and also other mechanisms.

This was a prospective study conducted in order to evaluate and compare pain scores through visual analogue scale, length of hospital stay and follow up in patients of benign renal disease and early renal malignancy. This study was conducted in the Department of Surgery, Batra Hospital and Medical Research centre, New Delhi. For the purpose of this study, a total number of 80 patients participated willingly after giving written informed consent. Out of these 40 were operated through open route and 40 patients underwent laparoscopic nephrectomy. Patients were grouped based on their route of surgery into open and laparoscopic groups. The comparison between them was made in relation to need for analgesia, hospital stay and convalescence. Follow up was done at 1 week, 4 weeks, 3 months and every six months so as to look for any delayed complications, chronic pain and recurrence in case of malignant disease. Female patients in the reproductive age group were more common in patients operated by laparoscopic route while as males were more common in open nephrectomy group. Laparoscopic group had lesser pain scores but on statistical analysis there were no signicant differences between the two groups. Mean hospital stay was (6.3 ±1.34) days in open group while as (4.2 ±1.22) days in the laparoscopic group. This study demonstrated that acute post operative pain scores were not different statistically between the two groups. Mean length of hospital stay was more in open group as compared to laparoscopic group. The cost of surgery was more in the laparoscopic group in comparison to open nephrectomy group. However, due to brief hospital stay, lesser morbidity, shorter convalescence and overall costs laparoscopic method was more useful in comparison with open route nephrectomy.

Introduction: Dyslipidemia is the most common threat in connection to developing cardiac disorders in type two diabetes mellitus. It has a role in the eventual development of atherosclerosis and increased mortality and morbidity. The present study was conducted to determine the lipoprotein abnormalities found in type two diabetic patients in the Mangalore region in South India. Methods: A cross-sectional study was conducted involving 95 types two diabetic patients. A fasting venous blood sample was obtained from these patients. The levels of different lipoproteins were estimated using the VITROS 5600 automatic analyzer. The patients were divided into two groups for comparison based on their duration of diabetes mellitus. The statistical tools used were the independent t-test for the comparison of the means of both quantitative variables and the Chi-square test for the proportion comparisons. The statistical package used was the Statistical Package for Social Sciences (SPSS) version 22. Results: According to the results of this study, deranged lipid profile levels were seen in most of the diabetic patients in group two. It was observed that about 67.3% of the patients in group 2 had higher serum cholesterol levels while a relatively lower number had a high level of cholesterol in group one. There was a significant (p-value of < 0.001) association between the two groups. There was an insignificant association between diabetes mellitus and high-density lipoprotein levels. In this study, triglyceride levels were also very high in most of the diabetic patients (p-value of 0.003), further increasing the risk of obesity and metabolic syndrome. Very low-density lipoprotein and low-density lipoprotein levels were also significantly increased with a significant p-value. Conclusion: Most diabetic patients tend to have dyslipidemias. Screening them for dyslipidemias may be useful to prevent insulin resistance, atherosclerosis, and metabolic syndrome. Drugs like statins inhibit the rate-limiting step of cholesterol biosynthesis, leading to a lower blood cholesterol. This may help to normalize their lipid profiles and to prevent severe adverse outcomes like coronary artery disease and stroke in diabetic patients. A healthy lifestyle and dietary modifications may also help to promote good health in the patients with diabetes mellitus.

Environmental pollution is a serious problem nowadays, especially due to growing industrialization and urbanization. The use of water bodies for waste disposal has led to devastating effects both on human and aquatic life. The contamination of drinking water has an equal impact on the health of children as well as adults. Aquatic fauna also gets affected due to deprivation of oxygen supply to these organisms as a result of water pollution. Various microbial diseases like cholera, hepatitis (usually subtype E), amoebiasis, gastroenteritis, shigellosis, and various other viral and parasitic infections spread through contaminated drinking water or food. The contamination of water bodies by different types of heavy metals cannot be under estimated. In Japan, contamination of water bodies by cadmium has led to cadmium nephropathy and Itai-Itai disease. Similarly, Minimata disease is a severe 2form of neuropathy induced by contamination of water bodies due to mercury and its various compounds. Lead poisoning also influences the health of people, and one of the sources being contamination in the water bodies. Strategies should be developed for the prevention of waterborne diseases, and awareness programs are the need of the day to prevent such illnesses in the future. Nature is divine, and therefore, it is important to prevent pollution in any form and nurture both aquatic life and human health and, as a whole, our ecosystem.

Introduction: Advanced glycation end products (AGEs) and diabetes duration have roles in the development of the vascular complications associated with morbidity and mortality in diabetic patients. The present study was conducted to estimate and find the association between serum fluorescence levels of advanced glycation products with diabetes duration and glycemic control in type 2 diabetic patients. Methods: 46 patients who had diabetic duration of less than ten years and 49 patients with duration more than ten years were included in the study. Serum fluorescence of AGEs was measured using a simple spectrofluorometric method. Correlations of AGEs with diabetes duration, fasting glucose, and glycated hemoglobin levels were analyzed. The incidence of microvascular complications in patients of both groups was examined. Results: Significantly higher serum fluorescent AGE levels (p < 0.001) and higher incidence of microvascular complications (p = 0.000) were found in diabetic patients who had diabetes duration of more than ten years, poorer glycemic control and higher age. Serum levels of fluorescent AGEs showed significant positive correlations with duration of diabetes mellitus, glycated haemoglobin and fasting glucose levels. Conclusion: Screening patients for AGEs, intensive glycemic control, and therapeutic strategies that target molecular mechanisms involving advanced glycation end products are warranted in older patients with longer diabetes duration to minimize their risk of developing complications.

Introduction: Enhanced formation and accumulation of Fluorescent Advanced Glycation End products (F-AGEs) in diabetes mellitus have been linked to increased risk of developing the associated vascular complications. Aim: To evaluate the potential of serum fluorescence levels of F-AGEs as screening tools to distinguish between type 2 diabetic patients with and without microvascular complications such as retinopathy, neuropathy. Materials and Methods: This cross-sectional study was conducted between June 2016 and June 2017, included 95 type 2 diabetic patients with more than 1 year of diabetes duration. Fasting blood glucose, glycated haemoglobin and total protein levels were estimated by automated methods. Serum F-AGEs were estimated by using a simple spectrofluorometric method. Microvascular complications due to diabetes mellitus were studied in each patient from medical records data on fundus examination for retinopathy and touch, vibration sensation detection for neuropathy. Diabetic patients were categorised into two groups as those without microvascular complications and those with microvascular complications-retinopathy and neuropathy. Statistical tests used for comparisons between groups were chi-square test for gender distribution, independent t-test for other parameters and Pearson’s correlations. The p-value <0.05 indicated significant difference between variables. Results: Mean age of the population was 55.1±5.3 years. Diabetic patients with microvascular complications (n=26) in the form of retinopathy, neuropathy had significantly higher levels of serum F-AGEs with mean 7.4±1.8 AU/g protein compared with diabetic patients without complications with mean value 1.5±0.7 AU/g protein (p<0.01). Conclusion: Two categories of serum fluorescent AGE values, without overlap, could be distinguished between diabetic patients with and without complications. Measurement of serum F-AGEs products has the potential to emerge as a simple, valuable screening tool to distinguish between diabetic patients with and without microvascular complications.
