argyrophilic staining of nucleolar organizer regions (agnor) has been considered to be useful in the diagnosis and prognostic evaluation of different cutaneous tumors. in order to evaluate the role of the agnor technique in discriminating aggressive from non-aggressive basal cell carcinoma (bcc), paraffin-embedded histologic sections from 30 cases of aggressive bcc (bcc2) and 30 cases of non-ag...

nucleolar organizer regions (nor) are defined as nucleolar components containing a set of argyrophilic proteins which are selectively stained by colloidal silver nitrate staining. although studies have shown that the number of nor dots or particles is directly related to the rapidity of cell proliferation in cancer cells, prognostic or diagnostic value of nor remains controversial. the aim of t...

background: tuberculosis continues to be a serious public health problem causing nearly three million deaths per year all over the world. despite major improvement in diagnosis, it is not possible to control the disease in the absence of surveillance treatment, and follow-up programs. objectives: this research was designed to study the frequency of mycobacterium tuberculosis among specimens ref...


 Purpose: To investigate the therapeutic effect of dexamethasone on rabbits suffering from oral ulcers, and underlying mechanism(s) action.
 Methods: A rabbit model ulcer was established by applying 40 % glacial acetic acid solution to buccal membranes animals. Three groups were used. Changes in area recorded after administration. Levels epidermal growth factor (EGF) assayed using re...

PURPOSE A sentinel node is defined as the initial lymph node, to which cancer cells metastasize from a primary tumor. Recently, sentinel node navigation surgery has been done using the dye-guided method. However, no study has shown that a lymph node detected by the dye-guided method is the true sentinel node from the viewpoint of micrometastasis. Micrometastases of lymph nodes, in which no meta...

Purpose: To investigate the effect of isosorbide mononitrate on diabetic cardiomyopathy (DCM), and potential mechanism action.Methods: The effects + GW4869 cardiac function myocardial fibrosis in DCM rats were determined via hemodynamics, hematoxylin-eosin (H&E) staining Masson staining. Exosomes extracted from serum, differential expressions microribonucleic acids (miRNAs) related to by re...

In the frame of atopic dermatitis (AD), epidermis restricted delivery corticosteroids represents a promising strategy for drug efficiency improvement, blood transfer diminution and therefore side effects decrease. Multi-lamellar liposomes (MLLs) controlled size, charge elasticity are good candidates to reach such purposes. Their entrapment hydrophilic hydrophobic molecules ability plain MLLs re...

Dental caries is the most prevalent oral disease that continues to affect almost every country in world. The contemporary management of dental focuses on non-restorative, non-invasive, and micro-invasive treatment approaches arrest or reverse process at a lesion level reduce loss sound tooth structure. One these employment arresting agents possess antibacterial remineralizing properties. Silver...

In this study, cell death regulation and induction in AML line from a relapsed MLL-rearranged model (MOLM-13) was investigated with doxorubin (Dox) betulinic acid (BetA), singly combination. CyQUANT Direct® Annexin V/propidium iodide double staining were used to measure the cytotoxic effects of compounds, respectively. Reactive oxygen species (ROS) generation measured using 2′,7′-dichlorofluore...

Protozoan contamination in produce is of growing importance due to their capacity cause illnesses consumers fresh leafy greens. Viability assays are essential accurately estimate health risk caused by viable parasites that contaminate food. We evaluated the efficacy reverse transcription quantitative PCR (RT-qPCR), propidium monoazide coupled with (q)PCR, and viability staining using iodide thr...
