The purpose of this study was to evaluate the effect of a single dose of ionizing radiation (30 Gy) on the osseointegration of implants in the rabbit tibia. Twenty rabbits received two dental Morse-tapered junction implants and one implant in each tibia. The animals were randomly divided into two groups (n=10), non-irradiated (NoIr) and irradiated (Ir), wherein the Ir group received a single dose of 30 Gy radiation 2 weeks after implant installation.

Article Synopsis
- A study was conducted to investigate the presence and characteristics of Staphylococcus spp. in both hospitalized and non-hospitalized cats, focusing on methicillin-resistant strains.
- A total of 218 swabs were taken from 109 cats, and various identification and genetic analysis techniques were used to isolate and categorize the bacteria.
- The findings indicated that S. felis was most common in non-hospitalized cats, while MRS strains such as MRSH and MRSP were primarily found in hospitalized ones, with factors like antibiotic use, hospitalization, and comorbidities linked to higher prevalence rates.
Background: Breast cancer has several subtypes, including HER2-positive breast cancer, which is characterized by overexpression of human epidermal growth factor receptor 2 (HER2), aggressiveness, poor prognosis, and high risk of recurrence and metastasis. Brain metastases are a common complication of HER2-positive breast cancer, but brain imaging is not included in the initial staging of this disease. This prospective pilot study aimed to evaluate the usefulness of brain computed tomography (CT) in the initial staging of HER2-positive breast cancer.

- This study examined how effective a drug-modified tissue conditioner is for treating denture stomatitis in Wistar rats infected with Candida albicans.
- Rats wore contaminated devices for 4 days, after which different treatments, including antifungal agents nystatin and chlorhexidine, were added to tissue conditioners, showing a notable reduction in microbial presence.
- Results indicated that integrating antifungal agents into soft tissue conditioners can significantly improve treatment outcomes for denture stomatitis.
Background: Açaí, a Brazilian native fruit, has already been demonstrated to play a role in the progress of breast cancer and cardiotoxicity promoted by chemotherapy agents. Thus, the present study aimed to evaluate the combined use of açaí and the FAC-D chemotherapy protocol in a breast cancer model in vivo.
Methods: Mammary carcinogenesis was induced in thirty female Wistar rats by subcutaneous injection of 25 mg/kg 7,12-dimethylbenzanthracene (DMBA) in the mammary gland.
