BACKGROUND: Handling of breast specimen is not well monitored and there is limited data on the impact of fixative solutions on specimen weights. Weight of resected breast tissue acts as a guide for future reconstructive and symmetrisation procedures. The aim is to quantitatively evaluate the discrepancies in weight of fresh breast specimen and the weight of specimen after being kept in a fixative solution for a variable length of time. METHODS: Single centre retrospective cohort study including patients undergone breast surgery for both diagnostic and therapeutic purposes between January of 2013 and June 2015...

Joo-Eun Kim, Young-Joon Park
Paclitaxel (PTX) is a effectively chemotherapeutic agent which is extensively able to treat the non-small cell lung, pancreatic, breast and other cancers. But it is a practically insoluble drug with water solubility less than 1 µg/mL, which restricts its therapeutic application. To overcome the problem, hyaluronic acid-complexed paclitaxel nanoemulsions (HPNs) were prepared by ionic complexation of paclitaxel (PTX) nanoemulsions and hyaluronic acid (HA) to specifically target non-small cell lung cancer. HPNs were composed of DL-α-tocopheryl acetate, soybean oil, polysorbate 80, ferric chloride, and HA and fabricated by high-pressure homogenization...

BACKGROUND: Breast milk administration prevents necrotizing enterocolitis (NEC). However, the mechanism remains unclear. Exosomes are cell-derived vesicles highly present in human milk and regulate intercellular signaling, inflammation, and immune response. We hypothesized that milk-derived exosomes beneficially affect intestinal epithelial cells. METHODS: Rat milk was collected, and exosomes were isolated using ExoQuick reagent and visualized by Nanoparticle Tracking Analysis...

Whether upper-limb swelling is associated with axillary web syndrome (AWS) is unknown. We recruited unilateral breast cancer (BC) patients who were scheduled for surgical intervention and lymph node dissection. The pre-operative assessment and post-operative assessment 3-4 weeks after surgery evaluated the upper-limb circumferential measurements, segmental limb volume, pain scores, grasp, shoulder range of motion (ROM), shoulder muscle power and quality-of-life scores. In the control group, the peri-elbow volume and upper-arm volume were significantly higher post-operatively than pre-operatively...

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)...

Design of a new drug entity is usually preceded by analysis of quantitative structure activity (properties) relationships, QSA(P)R. Six newly synthesized succinimide derivatives have been determined for (i) in silico physico-chemical descriptors, pharmacokinetic and toxicity predictors, (ii) in vitro biological activity on four different carcinoma cell lines and on normal fetal lung cells and (iii) lipophilicity on liquid chromatography. All compounds observed were predicted for good permeability and solubility, good oral absorption rate and moderate volume of distribution as well as for modest blood brain permeation, followed by acceptable observed toxicity...

PURPOSE: Fibroglandular tissue may mask breast cancers, thereby reducing the sensitivity of mammography. Here, we investigate methods for identification of women at high risk of a masked tumor, who could benefit from additional imaging. METHODS: The last negative screening mammograms of 111 women with interval cancer (IC) within 12 months after the examination and 1110 selected normal screening exams from women without cancer were used. From the mammograms, volumetric breast density maps were computed, which provide the dense tissue thickness for each pixel location...

: 267 Background: Breast cancer-related lymphedema (BCRL) is a known morbidity from treatment, and yet published estimates of its incidence are highly variable. Typically, a single volume measurement is recorded and the degree of intra-rater variability undefined. A threshold 5% limb volume change over time is used to define "mild lymphedema." Therefore, small variations in volume measurements could substantially lead to over or under-diagnosis of BRCL. Gage R&R is a measurement systems analysis tool that quantifies the amount of variability induced in measurements by the measurement system itself and compares this to the total variability observed...
