Background: For locally advanced breast cancer, neoadjuvant chemotherapy (NAC) is the standard of care for downstaging the tumor prior to surgery, and improved prognoses that are associated with pathological complete responses (pCR) have been noted, particularly in patients with human epidermal growth factor receptor 2 (HER2)-positive and triple negative (TN) tumors.
Objective: The aim of this study was to assess the differences in pathological responses among intrinsic subtypes of local lesions and status of axillary lymph nodes (Ax LN).
Methods: A consecutive series of 134 patients with locally advanced breast cancer who were treated with NAC was analyzed. Tumors were classified into the following 5 subtypes according to immunohistochemical staining results: Luminal A type, Luminal B type (HER2-negative and HER2-positive), HER2 type, and TN type.
Results: In Luminal A, Luminal B (HER2-negative), Luminal B (HER2-positive), HER2, and TN tumors, the pCR rates were 10% (4 of 40), 19% (8 of 42), 42% (8 of 19), 59% (10 of 17), and 38% (6 of 16), respectively. HER2-positive tumors showed good therapeutic effects, while Luminal A tumors showed less therapeutic effects.
Conclusions: Strategies that are determined according to intrinsic subtypes are becoming very important in the treatment of locally advanced breast cancer.

The efficacy of photodynamic treatment (PDT) against deep-seated tumor is hindered by low penetration depth of light as well as hypoxic conditions which prevails in tumor. To overcome this limitation, Near-infrared (NIR) absorbing photosensitizers have been investigated actively. In the present study we evaluated the PDT efficacy of an NIR absorbing chlorophyll derivative 'Cycloimide Purpurin-18 (CIPp-18)' in Human Breast carcinoma (MCF-7) and cervical adenocarcinoma (Hela) cells under normoxic and hypoxic conditions.

Down syndrome (DS) is strongly associated with Alzheimer's disease (AD) due to APP overexpression, exhibiting Amyloid-β (Aβ) and Tau pathology similar to early-onset (EOAD) and late-onset AD (LOAD). We evaluated the Aβ plaque proteome of DS, EOAD, and LOAD using unbiased localized proteomics on post-mortem paraffin-embedded tissues from four cohorts (n = 20/group): DS (59.8 ± 4.

Radiotherapy (RT) is widely applied in tumor therapy, but inevitable side effects, especially for skin radiation injury, are still a fatal problem and life-threatening challenge for tumor patients. The main components of topical radiation protection preparations currently available on the market are antioxidants, such as SOD, which are limited by their unstable activity and short duration of action, making it difficult to achieve the effects of radiation protection and skin radiation damage treatment. Therefore, we designed a drug-free antioxidant hydrogel patch with encapsulated bioactive epidermal growth factor (EGF) for the treatment of radiation skin injury.

Biological invasions are a major threat to biodiversity, ecosystem functioning and nature's contributions to people worldwide. However, the effectiveness of invasive alien species (IAS) management measures and the progress toward achieving biodiversity targets remain uncertain due to limited and nonuniform data availability. Management success is usually assessed at a local level and documented in technical reports, often written in languages other than English, which makes such data notoriously difficult to collect at large geographic scales.
