We have presented here magnetic tunnel junction (MTJ) model based universal NAND and NOR logic gates and studied the proposed universal gates by both experimental and simulation methods. Experimental results substantiates with both the simulated and theoretical results.

Global crop production must substantially increase to meet the needs of a rapidly growing population (8.2 billion in 2024). This is constrained by the availability of nutrients, water and land. There is also an urgent need to reduce the negative environmental impacts of crop production. Collectively, these issues represent one of the greatest challenge of the 21st century (Jeffery A., 2020). Sustainable cropping systems should be based on ecological principles which are the core of integrated approaches to solve the many challenges those are being faced by the large human population in India. Keeping in view the facts in to account, some emerging newly alternative cropping systems have been developed to resolve the present constraints (Meena et al. 2023).The innovative approaches for sustainable agriculture are integrated nutrient management via inclusion of green manure crops/ cover crops and mulching of soil surface through agriculture based byproducts.

Few discoveries and research in medical innovation have had the transformative potential of gene therapy. Amongst the most significant recent developments is Zolgensma, a pioneering spinal Muscular Atrophy (SMA) treatment. This infrequent but devastating genetic disorder disturbs the motor nerve cells in the spinal cord and is characterized by progressive muscle weakness and paralysis.
SMA has long been a source of despair for families worldwide; it claims the lives of many children before their second birthday. However, the advent of Zolgensma, approved by the FDA in 2019, represents a beacon of hope for families grappling with this disease, often seen as a death sentence for infants.

World Health Organization defines diarrhea as “the passage of three or more loose or liquid stools per day or more frequent passage than is normal for the individual”. Diarrhea is a form of gastrointestinal infection caused by a variety of bacterial, viral and parasitic organisms or through contaminated food or drinking water, or from person to person as a result of poor hygienic practices. It remains a major cause of mortality among under-age children (mostly under 5years) around the world, especially in developing world. Diarrheal disease is the third leading cause of infant and child mortality in developing countries and about 1.8 million children die per annum from this disease [1]. The number of diarrheal deaths is ridiculously on the high side despite a fall in childhood diarrheal diseases from 4.6 million to 0.8 million over the last three decades [2]. Diarrhea is a leading killer of children, accounting approximately 9% of all death among children under age 5 worldwide in 2019. This translates to over 1,300 young children dying each day, or about 484,000 children a year, despite the availability of a simple treatment. According to UNICEF [3], the death caused by diarrhea among children under-5 are highest in South Asia and Sub-Saharan Africa. In Nigeria, the percentage death caused by diarrhea in children was 16%. The overall prevalence of diarrhea as of 2021 was 12.9% [4]. In 2023, according to World Health Organization, diarrhea disease death in Nigeria among children reached 144,724 or 9.77% of total death [5].

As we usher in the new year with the first issue of 2024, it is my pleasure to contribute to the discourse within the esteemed pages of Medicon Dental Sciences. This editorial aims to shed light on the transformative landscape of dentistry, particularly the paradigm shift brought about by advancements in minimally invasive dentistry (MID).

Traditionally, dental interventions often involved invasive procedures, causing discomfort and anxiety among patients. However, the field has witnessed remarkable progress in recent years, emphasizing a more patient-centered and conservative approach.

To live a healthy life style and be free from diseases, fruits must be incorporated in one’s daily food. Fruits are of high nutritional value and provide the body with the required daily allowance. They are highly perishable, but can be made into different products to make them available all year round. They can be processed into products which includes; fruit juice, jellies, marmalades, candies, fruit bars and jams. This study analyses jam produced using date powder and compared it with commercial jam produced using table sugar. The percentage compositions of the blends considered were 50%:50%; 70%:30%; 30%:70% of orange and apple pulps respectively with constant amount of date powder (50%). In addition to the pulp blends, 2.9% commercial pectin was added together with citric acid, and date powder. The entire mixture was heated at 120°C for 25 mins to enhance the viscosity of the blends. Proximate, microbial, physico-chemical analyses, sensory evaluation and Vitamin constituents of the experimental samples and the commercial jam were evaluated. The commercial jam was found best having higher scores in all the sensory parameters. However, in respect to proximate composition, the experimental samples had the highest in protein, ash, moisture, and fibre while the commercial jam only scored high in fat, carbohydrate. In respect to microbial count minimum fungal and bacterial growth, 1.00 cfu X 103 g-1 and 1.00 cfu X 105 g-1 respectively were recorded in the experimental samples at 3 weeks after production. The control sample had the highest value in vitamin A content (130.35mg/100g) and the least in vitamin C content (1.64mg/100g).The nutritional analysis and sensory evaluation obtained proved that the orange and apple jam samples made with date powder is a promising functional product which can be consumed by both young and adults.

Gene therapy is a fantastic new technology that has opened up a plethora of options to treat or prevent previously untreatable diseases. Gene therapy is the use of nucleic acids (either DNA or RNA) is used to  manipulate the genetic information of a patient’s cells. This is particularly helpful for diseases like Cystic Fibrosis where the ability to add a gene that makes the protein product the patient lacks or to just the gene itself is ideal. The addition of CRISPR-Cas for easier and more streamlined gene editing has also been a boon. However, the unfortunate truth is that despite decades of research, only a few gene therapies have made it to market. One of those reasons is the problems with carriers of gene therapy. For over three decades viral vectors were considered the go to for gene therapy carriers however they aggravate the immune system and can cause unwanted genotoxicity. This compromises their usefulness as a therapeutic treatment or preventative. So other methods of gene therapy carriers have been considered. Nanotech deliverers such as exosomes, gold nanoparticles, and others have shown great promise of being able to transport gene therapy with mitigated or no toxicity to the patient. This review will briefly go over both viral vector and nanotech non-viral vector alternatives to delivery of gene therapy.

Transdermal drug delivery refers to the drug administration route through the skin that achieves the local or systemic treatment approved for clinical use. It is the third-largest drug delivery system after oral administration and injection. The advantages of the transdermal route are that the administration route of the drug is convenient and could reduce the fluctuation of blood drug concentration and toxic side effects. What is more, the drug could bypass the first-pass side-effect of the liver to prevent the drug from being destroyed in the gastrointestinal tract. Invasomes are new modified liposomes that differ from the liposomal vesicles in that they contain essential volatile oils, which are called terpenes. Also, ethanol in a low percentage is present in the vesicle either in the phospholipid layer or in the hydrous core. These modified newly discovered vesicles are intended to be used for topical and transdermal drug delivery due to their permeation effect and high deformability as compared to transferosomes.

Design and use of enzyme inhibitors against viral enzymes is one of the new and effective ways to control viruses and treat viral infections, Enzyme inhibitors inactivate these enzymes by binding to the nucleotides functional groups of the virus vital enzymes, thus can directly disrupt the virus replication cycle and indirectly prevent the spread of viral infections by reducing and controlling the population and number of viruses, these inhibitors, on the one hand, inhibit the virus by filling and Occupying the active sites of the enzyme and on the other hand, they change the stereochemistry of the enzyme by binding to the structure of the enzyme, for this reasons, they are used as an effective and complementary drug in the treatment of infections and viral diseases. Human Immunodeficiency Virus (HIV) is a retrovirus because it has the reverse transcriptase enzyme. Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs) are a class of Antiretroviral HIV drugs. Non- ucleoside Reverse Transcriptase Inhibitors (NNRTIs) block HIV reverse transcriptase enzymes by connecting to it. Tetrazole derivatives have strong antiviral activity against efavirenz and nevirapine-resistance viruses that have different genetic mutations. In this research, we study NNRTIs function and overview synthesis of 5-aryloxy- etrazole derivatives in the development path of NNRTIs.
