Modulation of the tumor microenvironment in non-muscle-invasive bladder cancer by OncoTherad® (MRB-CFI-1) nanoimmunotherapy: effects on tumor-associated macrophages, tumor-infiltrating lymphocytes, and monoamine oxidases.

Non-muscle-invasive bladder cancer (NMIBC) presents management challenges due to its high recurrence rate and a complex tumor microenvironment (TME). This study investigated the effects of OncoTherad® (MRB-CFI1) nanoimmunotherapy on the TME of BCG-unresponsive NMIBC, focusing on alterations in monoamine oxidases (MAO-A and MAO-B) and immune markers: CD163, FOXP3, CD8, and CX3CR1. A comparative analysis of immunoreactivities was made before and after OncoTherad® treatment and an immune score (IS) was established to evaluate the correlation between immunological changes and clinical outcomes.

Effects of probiotic supplementation on chronic inflammatory process modulation in colorectal carcinogenesis.

The current study investigated the potential effects of probiotic supplementation on colorectal carcinogenesis chemically induced with 1,2-dimethylhydrazine (DMH) and treated with 5-fluorouracil (5FU)-based chemotherapy in mice. Animals were randomly allocated in five different groups: Control: which not receive any treatment throughout the experimental course; Colitis model group (DMH): treated with DMH; DMH+ 5FU: animals received I.P.

OncoTherad (MRB-CFI-1) Nanoimmunotherapy: A Promising Strategy to Treat Bacillus Calmette-Guérin-Unresponsive Non-Muscle-Invasive Bladder Cancer: Crosstalk among T-Cell CX3CR1, Immune Checkpoints, and the Toll-Like Receptor 4 Signaling Pathway.

This study assessed the safety and efficacy of OncoTherad (MRB-CFI-1) nanoimmunotherapy for non-muscle invasive bladder cancer (NMIBC) patients unresponsive to (BCG) and explored its mechanisms of action in a bladder cancer microenvironment. A single-arm phase I/II study was conducted with 44 patients with NMIBC who were unresponsive to BCG treatment. Primary outcomes were pathological complete response (pCR) and relapse-free survival (RFS).

OncoTherad is an immunomodulator of biological response that downregulate RANK/RANKL signaling pathway and PD-1/PD-L1 immune checkpoint in non-muscle invasive bladder cancer.

Intoduction: Bladder cancer is the second most common urinary tract cancer. Above 70% of the occurrence of bladder cancer is superficial (pTis, pTa, and pT1), non-muscle invasive tumor (NMIBC), and the incidence of invasive disease is occasional. Treatments for NMIBC consist of transurethral resection (TUR) and subsequently intravesical immunotherapy with Bacillus Calmette-Guérin (BCG), intending to prevent tumor progression and decrease recurrence.

Effects of combined OncoTherad immunotherapy and probiotic supplementation on modulating the chronic inflammatory process in colorectal carcinogenesis.

This study evaluated the effects of combined OncoTherad immunotherapy and probiotic supplementation on colorectal carcinogenesis chemically induced with 1,2-dimethylhydrazine (DMH) in mice. The animals were randomly allocated in five groups: Control, DMH: did not receive any treatment; DMH + OncoTherad: received weekly I.P.

In-office bleaching protocols using violet LED: A split mouth case report.

A new LED wavelength, violet LED (VL) with a wavelength between 405 - 410 nm was recently introduced to be used for in-office dental bleaching. In comparison to the blue LED system (440 to 485 nm), the shorter wavelength has more energy carried in its photons and also corresponds to the absorption peak of the stained particles, which lead to whitening utilizing a physical process. Considering the need to suggest and develop new protocols with this new technology, this article reports 2 different dental bleaching protocols developed in a split-mouth model using VL.

Impact of Cooling on Lowering the Pain Threshold in Patients Undergoing Sclerotherapy.

Background: Liquid sclerotherapy is the treatment of choice for telangiectasias. However, pain caused by the procedure is a barrier to treatment adherence by patients.

Objective: To evaluate the use of skin cooling for the management of pain in patients undergoing liquid sclerotherapy.

Histopathological changes in androgenized ovaries are recovered by melatonin treatment.

Nandrolone decanoate (ND) is a synthetic steroid, which promotes adverse effects on the ovarian tissue, and melatonin (MLT) exhibits a number of beneficial properties in the reproductive system. This study evaluated the general features of the ovarian tissue and the immunoexpression of sex steroid receptors in ND-treated rats that were submitted to short-term melatonin treatment. Adult rats received mineral oil (control group) and ND at doses of 7.
