Immunofluorescence Analysis of Estrogen and Progesterone Receptors and Ki-67 Nuclear Protein in Canine Uteri Treated with Medroxyprogesterone Acetate During Anestrus

Int. j. morphol; 41 (3), 2023
SUMMARY: Estradiol and progesterone receptors play an essential role in the changes occurring in the uterus during the estrus cycle in dogs (Canis lupus familiaris). In order to investigate the potential effect of progestational agent medroxyprogesterone acetate (MPA) when is used during anestrus on the ...

Use of artificial intelligence to predict response to neoadjuvant chemotherapy in breast cancer

Mastology (Online); 33 (), 2023
:Breast cancer is the object of thousands of studies worldwide. Nevertheless, few tools are available to corroborate prediction of response to neoadjuvant chemotherapy. Artificial intelligence is being researched for its potential utility in several fields of knowledge, including oncology. The developme...

Effects of anastrozole on Ki-67 antigen expression in the vaginal epithelium of female rats in persistent estrus

Clinics; 75 (), 2020
OBJECTIVES: Aromatase inhibitors are the first-choice drugs for the treatment of hormone sensitive breast cancer. However, in addition to the scarcity of studies, there are controversies about their effects on vaginal epithelial cell proliferation in rats, especially those in persistent estrus. METHODS:...

Expresión de Ki67 y MUC-1 en el adenocarcinoma no especificado de otra manera (NOS) de glándulas salivales: su valor pronóstico

El adenocarcinoma NOS (no especificado de otra manera) es un tumor salival sin patrón especial poco mencionado en la literatura; su diagnóstico es un desafío porque estructuralmente no se identifica con otros carcinomas salivales más definidos. Por otro lado, Ki67 es un marcador de proliferación cel...

Could the intestinal epithelial alterations promoted by roux-en-y gastric bypass explain higher tendency for colonic diseases in bariatric patients?

ABCD (São Paulo, Impr.); 33 (4), 2020
ABSTRACT Background: Intestinal diversions have revolutionized the treatment of morbid obesity due to its viability and sustained response. However, experimental studies suggest, after these derivations, a higher risk of colon cancer. Aim: To analyze the histological and immunohistological changes that...

Association of menopausal status, expression of progesterone receptor and ki67 to the clinical response to neoadjuvant chemotherapy in luminal breast cancer

Abstract Objective To identify the biomarkers of response to neoadjuvant chemotherapy in early luminal breast cancer. Methods A cross-sectional study that included all patients with early or locallyadvanced luminal breast cancer submitted to neoadjuvant chemotherapy between 2013 and 2014. Demographic...

Cross-Sectional Study of Mandibular Canal Branching in Regions Affected by Dental Inflammation with Cone Beam Computed Tomography

ABSTRACT: The present study aimed to investigate the occurrence of mandibular canal alterations in regions with dental inflammation by means of cone beam computed tomography (CBCT). A database of 2,484 CBCTs was reviewed for identifying dental inflammation in mandibular alveolar ridges. The final sample ...

Pine ( Pinus densiflora ) needle extract could promote the expression of PCNA and Ki-67 after partial hepatectomy in rat

Acta cir. bras; 34 (6), 2019
Abstract Purpose To investigate the effects of pine needle extract (PNE) on the expression of proliferating cell nuclear antigen (PCNA) and Ki-67 during liver regeneration induced by 70% partial hepatectomy (PH) in rat. Methods Forty-eight male rats (SD, 7 weeks) had surgery (70% PH). They were randoml...

Evaluation of Kindlin-1 and Ki-67 immunohistochemical expression in primary cutaneous malignant melanoma: a clinical series

Appl. cancer res; 39 (), 2019
Background: The capacity for prognostic prediction of cutaneous melanoma, one of the most aggressive cancers, is still difficult due to the tumor heterogeneity and lack of reliable tumor markers. The objective of this study is to correlate, through immunohistochemistry, a Ki-67 and Kindlin-1 staining in ...

Ki-67 expression in mature B-cell neoplasms: a flow cytometry study

SUMMARY OBJECTIVE: Ki-67 is a nuclear protein associated with cellular proliferation in normal or leukemic conditions that can help identify more aggressive diseases and is usually evaluated with immunohistochemistry. The aim of this was to assess Ki-67 expression on mature B-cell neoplasms samples with...
