3D visualization of breast tumors are shown to be effective by previous studies. In this paper, we introduce a new augmented reality application that can help doctors and surgeons to have a more accurate visualization of breast tumors; this system uses a marker-based image-processing technique to render a 3D model of the tumors on the body. The model can be created using a combination of breast 3D mammography by experts. We have tested the system using an Android smartphone and a head-mounted device. This proof of concept can be useful for oncologists to have a more effective screening, and surgeons to plan the surgery...

Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...

(3-Aminomethylphenyl)boronic acid (AMPB)-installed hyaluronic acid-ceramide (HACE)-based nanoparticles (NPs), including manassantin B (MB), were fabricated for tumor-targeted delivery. The amine group of AMPB was conjugated to the carboxylic acid group of hyaluronic acid (HA) via amide bond formation, and synthesis was confirmed by spectroscopic methods. HACE-AMPB/MB NPs with a 239-nm mean diameter, narrow size distribution, negative zeta potential, and > 90% drug encapsulation efficiency were fabricated...

BACKGROUND: The inability to visualize the patient and surgical site directly, limits the use of current near infrared fluorescence-guided surgery systems for real-time sentinel lymph node biopsy and tumor margin assessment. METHODS: We evaluated an optical see-through goggle augmented imaging and navigation system (GAINS) for near-infrared, fluorescence-guided surgery. Tumor-bearing mice injected with a near infrared cancer-targeting agent underwent fluorescence-guided, tumor resection...

Despite enormous advances in remedies developed for breast cancer, an effective therapeutic strategy by targeting malignant cells with the least normal tissue toxicity is yet to be developed. Hsp90 is considered to be an important therapeutic target to inhibit cell proliferation. Geldanamycin (GDM), a potent inhibitor of Hsp90 was withdrawn from clinical trials due to its undesirable hepatotoxicity. We report a superparamagnetic iron oxide (SPION) based polymeric nanocomposite of GDM augmenting anticancer competence with decreased hepatic toxicity...

Breast cancer metastasis to the brain develops after a clinical latency of years to even decades, suggesting that colonization of the brain is the most challenging step of the metastatic cascade. However, the underlying mechanisms used by breast cancer cells to successfully colonize the brain's microenvironment remain elusive. Reelin is an archetypal extracellular glycoprotein that regulates migration, proliferation, and lamination of neurons. It is epigenetically silenced in various cancers, and its expression in multiple myelomas is linked to poor patient survival...

BACKGROUND: The use of implants is still the most common procedure for breast reconstruction because they are easy, less painful than tissue transplants, and do not need a donor site. However, it is challenging to find a suitable implant for patients with small breasts, and some women fear foreign bodies and possible complications or reoperations. Autologous breast reconstruction using the pedicled latissimus dorsi (LD) myocutaneous flap without an implant provides a good option for Asian women with small breasts...

While mass spectrometry (MS) imaging is widely used to investigate the molecular composition of ex vivo slices of cancerous tumors, little is known about how variations in the cellular properties of cancer tissue can influence cancer biomarker ion images. To better understand the basis for variations in the abundances of cancer biomarker ions seen in MS images of relatively homogeneous ex vivo tumor samples, sections of snap frozen human breast cancer murine xenografts were subjected to desorption electrospray ionization mass spectrometry (DESI-MS) imaging...

Experimental hypothyroidism retards mammary carcinogenesis promoting apoptosis of tumor cells. β-catenin plays a critical role in cell adhesion and intracellular signaling pathways conditioning the prognosis of breast cancer. However, the mechanistic connections associated with the expression of β-catenin in thyroid status and breast cancer are not known. Therefore, we studied the relationship between the expression and localization of β-catenin and apoptosis in mammary tumors induced by 7,12-dimethylbenz(a)anthracene (DMBA) in hypothyroid (Hypot) and euthyroid (EUT) rats...

Carboplatin is a less toxic analog of cisplatin, but carboplatin also has side effects, including bone marrow suppression. Therefore, to improve the capacity of the anticancer activity of carboplatin, we investigated whether combined treatment with carboplatin and thioridazine, which has antipsychotic and anticancer activities, has a synergistic effect on apoptosis. Combined treatment with carboplatin and thioridazine markedly induced caspase-mediated apoptosis in head and neck squamous cell carcinoma (AMC-HN4) cells...

The HLA-A11 or -A33 allele is found in approximately 18% or 10% of the Asian population, respectively, but each of which is a minor allele worldwide, and therefore no clinical trials were previously conducted. To develop a therapeutic peptide vaccine for each of them, we investigated immunological responses of advanced cancer patients with the HLA-A11(+) /A11(+) (n=18) or -A33(+) /A33(+) (n=13) allele to personalized peptide vaccine (PPV) regimens. The primary sites of HLA-A11+/A11+ or -A33+/A33+ patients were the colon (n=4 or 2), stomach (2 or 3), breast (3 or 2), lung and pancreas(2 or 2), and so on...

BACKGROUND: Nipple reconstruction in implant-based breast reconstruction remains challenging, as the remaining thin skin envelope results in a less projected neo-nipple with a reduced volume. This study presents a modified top-hat flap technique with rolled dermal grafts from the dog-ears of lateral wings for augmenting reconstructed nipples during implant-based breast reconstruction. METHODS: Between April 2011 and December 2014, among 34 patients who underwent immediate post-mastectomy reconstruction with a direct silicone implant, nipple reconstruction was performed using the modified top-hat flap technique in only 21 patients (group A), whereas 13 patients underwent the modified top-hat flap technique with rolled dermal grafts from the dog-ears of lateral wings (group B)...

BACKGROUND: Although autogenous tissue-based breast reconstruction has been widely used in the past decade, implant-based breast reconstruction is more often used in Taiwan because Asian women are generally slender with small breasts. For patients with very small breasts, it is hard to achieve the goal of reconstructing a similar breast to the contralateral one, even with the smallest size implant available commercially. Therefore, these patients need not only breast reconstruction but also contralateral breast augmentation...

BACKGROUND: Infection after breast augmentation occurs in 1.1% to 2.5% of patients. Bacterial contamination of the implants could explain some complications of breast implant surgery, including infection, capsular contracture and even anaplastic large cell lymphoma. Because of the evidence of bacterial spread from the nipple, nipple shields have been proposed as a routine maneuver to avoid contamination of the implants. OBJECTIVE: To determine if nipple shields are useful in transaxillary breast augmentation...

Many human cancers have been reported to have enhanced expression of the immune checkpoint molecule programmed death-ligand 1 (PD-L1), which binds to programmed cell death-1 (PD-1) expressed on immune cells. PD-L1/PD-1 plays a role in inhibition of antitumor immunity by inducing T cell apoptosis and tolerance. Thus, it is crucial to elucidate mechanisms of PD-L1 expression on cancer cells. ERO1-α is an oxidase located in the endoplasmic reticulum. It is overexpressed in a variety of tumor types and it plays a role in disulfide bond formation in collaboration with PDI...
