Background: Transitional Cell Carcinoma (TCC) of bladder is the second most common urogenital malignancy and because of its high rate of recurrence (two third of tumors recur) vigilant surveillance is necessary. There have been a lot of efforts to find a proper biomarker for detecting urothelial cancers because available methods are expensive and invasive (like cystoscopy) or have a low degree ...
background and objectives: numerous procedures in biology and medicine require the counting of cells. direct enumer- ation of colony forming units (cfus) is time-consuming and dreary accurate cell counting on plates with high numbers of cfus is error prone. in this study we report a new indirect cell counting method that was developed based on the use of redsafe fluorometric assay. the usefulne...
basal cell carcinoma (bcc) is the most common cancer of the skin. definite diagnosis usually requires histological examination but recently it has been suggested that cytological examination of skin smear can be used as an alternative. to evaluate sensitivity and specificity of cytological examination, a total of 125 skin lesions, clinically suspected to be bcc were studied. cytological samples...
Background & Objective: Basal cell carcinoma (BCC) is a common skin cancer arising from the basal layer of the epidermis and its appendages. They are locally invasive, aggressive, and destructive of skin and the surrounding structures. β-Catenin is a multifunctional protein located to the intracellular side of the cytoplasmic membrane coded by the CTNNB1 gene, which maps to chr...
Background: It is well known that, at the time of the initial presentation of patients with non-small cell lung cancer, N-status is very important in accurate staging and avoiding inappropriate surgical procedures. Also, if mediastinal lymph node metastasis (N2) of non-small cell lung cancer (stage IIIA) is present, neoadjuvant (preoperative) chemora-diotherapy is indicated therefore a quick an...
Background: This study aimed to evaluate the diagnostic value of outer dense fiber 4 (ODF4), melanoma-associated antigen A3 (MAGEA3), and MAGEAB4 mRNAs in transitional cell carcinoma (TCC), using a small amount of cell reverse transcriptase-polymerase chain reaction (RT-PCR) on urinary exfoliated cells. Methods: We recruited a total of 105 suspected TCC patients and 54 sex- and age-matched non-...
Mastitis is one of the most prevalent and costly diseases affecting dairy cattle production. In the present study, effects of tumor necrosis factor (alpha isomer) gene (TNF-α) polymorphisms on milk somatic cell count (SCS) and subclinical mastitis was investigated in 121 Holstein dairy cattle. The polymorphisms of a 303 bp fragment of TNF-α gene were investigated by PBR and PCR-SSCP techniques....
We investigate the use of a split-ring resonator (SRR) incorporated with an atomic-vapor cell to improve sensitivity and minimal detectable electric (E) field Rydberg atom-based sensors. In this approach, sub-wavelength SRR is placed around atomic vapor-cell filled cesium atoms for E-field measurements at 1.3 GHz. The provides factor 100 in enhancement measurement sensitivity. Using electromagn...
Background and Aims: Sleep disorders increase many diseases and a decrease physiological function. This study aimed to compare the effect of the two methods of high-intensity interval training (HIIT) and sleep regulation program and a combination of the two on insulin resistance and sensitivity, body fat percentage, and reaction time in adolescents with sleep disorders. Materials and Methods: ...
Background: Transrectal ultrasonography guided needle biopsy of prostate frequently used for early detection of cancer has faced the pathologists with a major diagnostic challenge. In recent years P504S has been used as a tumor cell marker for definitive diagnosis of prostatic cancer in small biopsy specimens.Methods: 70 prostate needle biopsies and 6 transurethral resections (TURP) containing ...
