Aim: Monascin and ankaflavin, the major fractions of the fungal-derived monascus yellow pigments, were incorporated with the herbal drug, resveratrol (RSV) within the core of folate-conjugated casein micelles (FA-CAS MCs, F1) for active targeting. PEGylated RSV-phospholipid complex bilayer enveloping casein-loaded micelles (PEGPC-CAS MCs) were also developed as passive-targeted nanosystem.
Results: FA- and PEGPC-CAS MCs demonstrated a proper size with monomodal distribution, sustained drug release profiles and good hemocompatibility. The coloaded MCs showed superior cytotoxicity to MCF-7 breast cancer cells compared with free drugs. Both nanosystems exerted excellent in vivo antitumor efficacy in breast cancer bearing mice with PEGylated MCs showing comparable tumor regression to folate-conjugated MCs.
Conclusion: Evergreen nanoplatforms coloaded with monascus yellow pigments and RSV were effective for breast cancer treatment.

Background: Breast cancer is a frequently diagnosed malignant disease and the primary cause of mortality among women with cancer worldwide. The therapy options are influenced by the molecular subtype due to the intricate nature of the condition, which consists of various subtypes. By focusing on the activation of receptors, Epidermal Growth Factor Receptor (EGFR) tyrosine kinase can be utilized as an effective drug target for therapeutic purposes of breast cancer.

Introduction: Management of pain associated with breast cancer surgeries is crucial in reducing incidence of postmastectomy pain syndrome. The pain distribution involves the anterior chest wall, axillary area and ipsilateral upper limb.
Objective: This study was designed to investigate the effect of bilevel erector spinae plane block (ESPB) with high thoracic block vs the conventional unilevel ESPB vs opioids in patients with cancer undergoing modified radical mastectomy regarding pain control and reducing pain in axilla.

Background: Breast cancer is the most common cancer among women. In response to the need to hospital stays and minimize waiting time for surgery, particularly during the COVID-19 pandemic, the National Cancer Institute developed the One Day Surgery with Breast cancer Home Recovery program (ODS BHR NCI). The aim of study is to assess the success rate of breast cancer surgeries conducted through this program and to evaluate the incidence of complications.

Immunogenic cell death (ICD) offers a promising avenue for the treatment of triple-negative breast cancer (TNBC). However, optimizing immune responses remains a formidable challenge. This study presents the design of RBCm@Pt-CoNi layered double hydroxide (RmPLH), an innovative sonosensitizer for sonodynamic therapy (SDT), aimed at enhancing the efficacy of programmed cell death protein 1 (PD-1) inhibitors by inducing robust ICD responses.

Cancer remains a leading cause of mortality, with aggressive, treatment-resistant tumors posing significant challenges. Current combination therapies and imaging approaches often fail due to disparate pharmacokinetics and difficulties correlating drug delivery with therapeutic response. In this study, we developed radionuclide-activatable theranostic nanoparticles (NPs) comprising folate receptor-targeted bimetallic organo-nanoparticles (Gd-Ti-FA-TA NPs).
