Abstract: During 2017 and 2018 seasons, Flame seedless grapevines received three sprays of amino acids at 0.1% either alone or in different combinations with vitamins A & B₁₂ each at 50 ppm and C at 500 ppm. The objective of this study was examining the effect of amino acid and vitamins on growth, vine nutritional status, yield and berries quality. Using amino acids at 0.1% either singly or in different combinations with vitamins A and B₁₂ each at 50 ppm and C at 500 ppm was very effective in improving growth, vine nutritional status, yield, berries colouration % and both physical and chemical characteristics of the berries relative to the control. Combined applications of amino acids and vitamins A, B and C were favourable than using amino acids alone in this respect. Carrying out three sprays at growth start, just after berry setting and at three weeks later of a mixture of amino acids at 0.1% plus vitamins A and B₁₂ ppm each at 50 ppm and vit. C at 500 ppm gave the best results with regard to yield and berries quality of Flame seedless grapevines.

Abstract: Infection with hepatitis B virus causes both significant morbidity and mortality accounting for an estimated 400 million chronic liver infections and diseases. This study aims at determining the prevalence and risk factors of HBV infections among adults in Sinkor, Greater Monrovia. This retrospective study used information recorded in the database of the SDA Cooper Hospital. Records of one hundred and thirty-four (134) adult patients (≥18) who attended the hospital from January – December, 2016 and were tested for HBV. the overall prevalence of HBV infection was 57 (45.24%). The prevalence was higher in males 43/87 (49.4%) than females 14/39 (35.9%). In terms of age group, the prevalence of HBV was highest, 27/39 (69.2%) in the age group of 30–39 years and lowest, 1/12 (8.3%) age group 70-79 years. Sexual contact and intravenous drug use were the main possible sources of infection as 43.9 % and 28.1 % of the patients were probably infected through these routes. The least possible sources of infection were surgical operations (1.8%) and blood transfusions (10.5%). Findings from this study revealed a high prevalence of HBV infections among adult patients, especially through intravenous drug use and sexual contact. The risk of HBV infection was also found to decrease with age.

Hematopoietic Stem Cell Transplantation Research Literatures

Abstract: Stem cells are derived from embryonic and non-embryonic tissues. Most stem cell studies are for animal stem cells and plants have also stem cell. Stem cells were discovered in 1981 from early mouse embryos. Stem cells have the potential to develop into all different cell types in the living body. Stem cell is a body repair system. When a stem cell divides it can be still a stem cell or become adult cell, such as a brain cell. Stem cells are unspecialized cells and can renew themselves by cell division, and stem cells can also differentiate to adult cells with special functions. Stem cells replace the old cells and repair the damaged tissues. Embryonic stem cells can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. This article introduces recent research reports as references in the related studies.

Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. CRISPR (clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found within the genomes of prokaryotic organisms such as bacteria and archaea. These sequences are derived from DNA fragments from viruses that have previously infected the prokaryote and are used to detect and destroy DNA from similar viruses during subsequent infections. Hence these sequences play a key role in the antiviral defense system of prokaryotes. Cas9 is an enzyme that uses CRISPR sequences as a guide to recognize and cleave specific strands of DNA that are complementary to the CRISPR sequence. Cas9 enzymes together with CRISPR sequences form the basis of a technology known as CRISPR/Cas9 that can be used to edit genes within organisms. This type of gene editing process has a wide variety of applications including use as a basic biology research tool, development of biotechnology products, and potentially to treat diseases. The CRISPR/Cas system is a prokaryotic immune system that confers resistance to foreign genetic elements such as those present within plasmids and phages that provides a form of acquired immunity. RNA harboring the spacer sequence helps Cas proteins recognize and cut foreign pathogenic DNA. Other RNA-guided Cas proteins cut foreign RNA. CRISPR are found in approximately 50% of sequenced bacterial genomes and nearly 90% of sequenced archaea. This article introduces recent research reports as references in the related studies.
