La reticulohistiocitosis multicéntrica es una enfermedad inflamatoria, una histiocitosis de células no Langerhans, poco frecuente y de etiología desconocida. Se clasifica como multicéntrica al presentar compromiso multisistémico. La enfermedad afecta predominantemente a la piel y las articulaciones,...
SUMMARY: Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that is highly expressed in various types of cancers including breast cancer. However, the role of AhR with its endogenous ligand 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) on the progression...

SUMMARY: Digit ratio established in utero is positivelly correlated with intrauterine level of estrogen. Since the breast cancer is related to excessive and prolonged exposure to estrogen, digit ratio might be considered as useful marker in breast cancer risk assessment. The aim of the present study was ...
BACKGROUND: The success of breast cancer (BC) treatment depends largely on the clinical-histological characteristics of the patient. Immunohistochemical (IHC) Breast Cancer Subtypes are crucial for therapeutic purposes. AIM: To determine the relevance and prevalence of the histopathological parameters an...
Breast cancer is associated with high frequency and mortality in Brazilian women. There have been limited studies portraying the characteristics of breast cancer cases in the countryside of the state of Minas Gerais for a long period of time, a fact that will allow us to better understand the epidemiolog...
Las lesiones metastásicas representan hasta un 3 % de los tumores malignos
de la glándula tiroides. La mayoría de los casos se originan de tumores de
células renales y de pulmón. El abordaje diagnóstico implica una alta sospecha
clínica en pacientes con primarios conocidos, sin embargo, puede ser ...
Abstract Paclitaxel (PTX) is one of the most effective drugs used in the treatment of breast cancer. Nonetheless, the appearance of MDR1 (multidrug resistance 1) in tumor cells has become a significant hindrance for efficacious chemotherapy. In this study, we show that the expression level of Egr-1 (earl...
Abstract This study aimed to investigate the activities of novel 20(R)-3,20-dihydroxy-19-norpregn-1,3,5(10)-trienes (kuz7 and kuz8b) of natural 13β- and epimeric 13α-series against triple-negative MDA-MB-231 breast cancer cells. High antiproliferative activity of synthesized compounds kuz8b and kuz7 a...
This is a comment on a study recently published about peritumoral infiltration of local anesthetic before surgery in early breast
cancer. Previously, animal models and a randomized study for stage IV breast cancer patients inferred that the removal of the
primary tumor resulted in increased growth fact...
