Chronic granulomatous disease is a non-prevalent genetic disorder due to different structural gene mutations encoding components of nicotinamide adenine dinucleotide phosphate oxidase complex. Nicotinamide adenine dinucleotide phosphate oxidase is a complex made by a group of five proteins (subunit) and plays an important role in the innate immune system. Five structural genes are responsible for encoding each subunit, in which cytochrome b-245 alpha chain (also known as p22-phox) is encoded by gene. Read More

Department of Microbiology, Isfahan University of Medical Sciences, Isfahan, Iran.

Human bocavirus (HBoV) was first characterized in nasopharyngeal aspirates from young children with acute respiratory infections. It is prevalent among children with acute wheezing. This study was carried out in order to analyze the infection frequency and coinfection rates of HBoV with respiratory syncytial virus (RSV) and to perform phylogenetic analysis of HBoV in samples of children with acute respiratory infection in Isfahan, Iran.

Clinical pitfalls of leishmaniasis and Whipple's disease hidden behind systemic lupus erythematosus: A case series.

Acta Microbiol Immunol Hung 2019 Sep 17;66(3):377-385. Epub 2019 May 17.

Department of Medical Sciences and Public Health and Unit of Allergy and Clinical Immunology, University Hospital "Duilio Casula", University of Cagliari, Monserrato (Cagliari), Italy.

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disease that can affect major organs possibly leading to life-threatening complications and appears with heterogeneous clinical picture. SLE could present with broad spectrum of clinical and laboratory features that can resemble those of other diseases, such as hemopoietic malignancies, infections, or immune-mediated disorders. Its complexity and protean features overlap with many other diseases, hindering the differential diagnosis. Read More

Murine models are suggested as the gold standard for scientific research, but they have many limitations of ethical and logistical concern. Then, the alternative host models have been developed to use in many aspects especially in invertebrate animals. These models are selected for many areas of research including genetics, physiology, biochemistry, evolution, disease, neurobiology, and behavior. Read More

Ah-receptors (AhRs) recognize and bind foreign environmental molecules as well as some target hormones of other nuclear receptors. As ligands activate transcription factors, they transmit the information on the presence of these molecules by binding to the DNA, which in turn activate xenobiotic metabolism genes. Cross talk with other nuclear receptors or some non-nuclear receptors also activates or inhibits endocrine processes. Read More
