Nicotine is regarded as the main active addictive ingredient in tobacco products driving continued tobacco abuse behavior (smoking) to the addiction behavior, whereas nicotinic acetylcholine receptors (nAChR) is the crucial effective apparatus or molecular effector of nicotine and acetylcholine and other similar ligands. Many nAChR subunits have been revealed to bind to either neurotransmitters or exogenous ligands, such as nicotine and acetylcholine, being involved in the nicotinic receptor signal transduction...

Cancer is a major burden of disease worldwide with considerable impact on society. The tide of immunotherapy has finally changed after decades of disappointing results and has become a clinically validated treatment for many cancers. Immunotherapy takes many forms in cancer treatment, including the adoptive transfer of ex vivo activated T cells, oncolytic viruses, natural killer cells, cancer vaccines and administration of antibodies or recombinant proteins that either costimulate cells or block the so-called immune checkpoint pathways...

Aspartame, an artificial sweetening agent belongs to dipeptide chemical category with a very strong sweetening potential. Although research findings in humans and non-human primates have demonstrated numerous negative effects of aspartame (biochemical, histological, neurological, behavioral, genetic etc)., the status of aspartame is still debatable. Present manuscript is a critical review of the substantial research findings related to aspartame intake on different research models. Purpose of this review was to spread the awareness about adverse effect of aspartame intake to outline the occurrence of health issues among the population...

BACKGROUND: C1q protein is composed of three protein chains (A, B and C) that are the products of separate genes. Genetic deficiencies in C1Q genes are important factors influencing the risk of systemic lupus erythematosus (SLE). Therefore, this study aimed to investigate the possible association of single nucleotide polymorphisms (SNPs) in the coding region of the C1Q genes with SLE. METHODS: To search for potential SNPs in the encoding regions of C1q A, B and C chains, Cq1 exons were initially amplified and directly sequenced from leukocyte DNA from a subset of Caucasian and African American SLE patients and healthy controls...

BACKGROUND AND OBJECTIVE: Feather wastes are the most abundant keratinous material in the nature and its accumulation causes multiple environmental problems. Nutritive value upgrading of such wastes through biological treatments may provide ruminant's rations with high quality and cost effective source of protein. Therefore, the main objective of this study was to investigate the potential uses of biologically treated feathers (BTF) as a feedstuff for ruminants through in vitro experiments...

BACKGROUND AND OBJECTIVE: Dengue is the most important arthropod-borne viral disease which caused by the four-dengue virus serotypes (1-4) and its incidence has grown dramatically around the world in the recent decades. This study was conducted to determine the molecular characterization of dengue virus genotypes spreading in Jeddah province. METHODOLOGY: To distinguish dengue virus genotypes, serum samples from 13 infected patients were subjected to envelop and non-structural 1 (E/NS1) gene amplification and sequence analysis at the nucleotide and amino acid levels...

BACKGROUND AND OBJECTIVE: The biogas sludge is generally not used optimally and people even pour it directly into the river that it cause environmental pollution. One of the ways to get the benefit from sludge and chicken blood meal or fishmeal is to use it as a substitute for bran in mushroom media. This study aimed to improve the nutrient content of biogas sludge with the addition of chicken blood meal (CBM) and fishmeal (FM) as substitute material for bran in white oyster mushroom media...

Plants provide the oxygen required for maintenance of human life. They are essential for human life in terms of food and health. Thousands of years ago, humans explored the therapeutic power of plants and preferred to benefit from them to live healthily. According to the data of the World Health Organization (WHO), the number of plants used for therapeutic purposes is around 20,000. Since the beginning of using plants for human health, the bioactivity characteristics of the plants have been studied in laboratories...

BACKGROUND AND OBJECTIVE: Rice (Oryza sativa L.) is a very important food crop in Indonesia. The development of upland rice becomes an alternative solution to meet the national rice needs. Upland rice productivity is lower than wetland rice, one of the causes is the use of low-vigor seeds. The seeds derived from previous harvest seed and newly harvested rice seedlings have physiological dormancy. Physiological dormancy relates to seed persistency. The study aimed to evaluate the persistence and development of invigoration technique to break seed dormancy of upland rice...
