In African catfish, two gonadotropin-releasing hormone (GnRH) peptides have been identified: chicken GnRH (cGnRH)-II and catfish GnRH (cfGnRH). The GnRH receptors on pituitary cells producing gonadotropic hormone signal through inositol phosphate (IP) elevation followed by increases in intracellular calcium concentration (¿Ca(2+)(i)). In primary pituitary cell cultures of male African catfish, ...

Cytokine signaling via various transcription factors regulates receptor activator of nuclear factor (NF)-kappaB ligand (RANKL)-mediated osteoclast differentiation from monocyte/macrophage lineage cells involved in propagation and resolution of inflammatory bone destruction. Protein inhibitor of activated STAT3 (PIAS3) was initially identified as a molecule that inhibits DNA binding of STAT3 and...

This paper explores the effects of general and agricultural trade openness on economic freedom and alongside with the quality of institutions, on income and poverty. Recent cross-country data for over 200 nations in global regions were used to estimate equations for income, poverty and economic freedom. Economic freedom appears to have positive impacts on income levels, which together with good...

Nowadays viral hepatitis is one of the most common and important causes of chronic liver disorders in the world. Extrahepatic manifestations of viral hepatitis consist a main part of the disease. The main viruses causing hepatitis include Hepatitis A, B and C viruses. Herein common skin manifestations in hepatitis C virus (HCV) are discussed. Chronic hepatitis causes skin disorders both directl...

micrornas (mirnas) represent a class of small non-coding rna molecules that regulate gene expression at the post-transcriptional level. they play a crucial role in diverse cellular pathways. ionizing radiation (ir) is one of the most important treatment protocols for patients that suffer from cancer and affects directly or indirectly cellular integration. recently it has been discovered that mi...

Objectives: The present research was carried out to explore the perceived impact of terrorist attacks in terms of dread, lack of control and extent of exposure in death anxiety. It was also intended to explore the moderating effect of resilient attributes, and religious beliefs were investigated. Methods: Sample consisted of 359 students (directly perceived =159, and in-directly perceived =20...

In the present study, we investigated the relationship between physical activity (PA) and self-esteem (SE), while introducing body mass index (BMI), perceived physical fitness (PPF), and body image (BI) in adults (N =264, M =38.10 years). The findings indicated that PA was directly and indirectly associated with SE. BMI predicted SE neither directly nor indirectly, but was directly associated w...
