Breast cancer is the most common cancer type among women all over the world. Chemotherapy is the use of anticancer medicines for treating cancer but it has many side effects and cells may become resistant to these chemical medicines. Therefore, finding new compounds of natural origin could be a promising solution to this problem. The aim of the current study was to evaluate anticancer activity ...

Marine algal community signifies a huge source of compound endowed with ingenious structure and potential biological activities. Cytotoxicity of plant or fungal material is considered as the presence of antitumor compounds. In this study, ethanol extracts of seaweeds Dictyota dichotoma var. velutricata, D. hauckiana, D. indica, Iyengaria stellata, Jolyna laminarioides, Melanothamnus afaqhusaini...

ultrasound guidance for pain interventions is becoming increasing recognized as a useful imaging tool. one of the common interventions where it is gaining wider acceptance is during the performance of a stellate ganglion block. the following is a unique report where intravascular and neuronal injury occurred during the performance of an ultrasound guided stellate ganglion block followed by dysp...

The micropyle number in the ova of sturgeon species from the South Caspian Sea was investigated. The study was conducted on female broodfishes of three species of sturgeon (Persian sturgeon Acipenser persicus, Stetates sturgeon A. stellatus and great sturgeon Huso huso) included 44 Persian sturgeon, 13 stellate sturgeon and 8 great sturgeon specimens. Fifty eggs were randomly collected from eac...

The main source of excitation to the ventral cochlear nucleus (VCN) is from glutamatergic auditory nerve afferents, but the VCN is also innervated by two groups of cholinergic efferents from the ventral nucleus of the trapezoid body. One arises from collaterals of medial olivocochlear efferents, and the other arises from neurons that project solely to the VCN. This study examines the action of ...

Hepatic stellate cells are liver-resident cells of star-like morphology and are located in the space of Disse between liver sinusoidal endothelial cells and hepatocytes(1,2). Stellate cells are derived from bone marrow precursors and store up to 80% of the total body vitamin A(1, 2). Upon activation, stellate cells differentiate into myofibroblasts to produce extracellular matrix, thus contribu...
