Mimicry of bioactive conformations is critical for peptide-based medicinal chemistry because such peptidomimetics may augment stability, enhance affinity, and increase specificity. Azapeptides are peptidomimetics in which the α-carbon(s) of one or more amino acid residues are substituted by nitrogen. The resulting semicarbazide analogues have been shown to reinforce β-turn conformation through the combination of lone pair-lone pair repulsion of the adjacent hydrazine nitrogen and urea planarity. Substitution of a semicarbazide for an amino amide residue in a peptide may retain biological activity and add benefits such as improved metabolic stability...

Partial resections of the breast are more than 50% of breast oncological surgery. The resulting defect can be substantial and cause meaningful deformity that leads to reduced body image satisfaction of the patients, affecting their ability to cope with the cancer. Parallel to the development of breast oncology techniques, an evolution of breast reconstruction techniques occurred. During the last decade, by using techniques from cosmetic breast surgery (such as breast reductions, augmentations and mastopexies), we can reconstruct extensive partial defects of the breasts at the immediate and delayed setting and achieve symmetrical aesthetic results...

The purpose of our investigation was to develop a novel and state of the art digital skin imaging method capable for remote monitoring and objective assessment of Radiation Induced Dermatitis (RID). Therefore, radiation therapy related side effects were assessed by medical experts according to Common Terminology Criteria for Adverse Events (CTCAE) grade of severity in 20 female breast cancer patients in a clinical trial over the treatment time frame of 25-28 radiation cycles, 50.0-50.4 Gy each. Furthermore the intensity of developed skin erythema was documented by using conventional spectrophotometry plus digital skin imaging...

OBJECTIVES: Psychological outcomes of aesthetic surgical procedures like hair transplantation are mostly positive including decreased anxiety, depression and social phobia and increased general well-being, self-efficacy and self-esteem. However, some patients may suffer from post-surgical depression and post-surgical increased suicide rates have been reported for breast augmentation patients. Difficulty adapting to the new image, unfulfilled psychological needs expected to be met by the surgery, side effects of the surgery like tissue swelling or bruising, uncontrolled pain, presence of body dysmorphic disorder and previous history of mood disorder may be some of the risk factors for post-surgical depression...

Heart failure has mortality rates that parallel those of breast cancer. Current management strategies include neurohormonal blockade, rate control measures, natriuretic peptide preservation, implantation of mechanical assist devices, and heart transplantation. Despite these strategies, however, the failing myocardium remains energy depleted. New strategies to promote metabolic recovery are being developed to potentially augment current treatment guidelines. For example, an unexpected finding of our own studies showed that mechanical unloading with assist devices in advanced-stage heart failure restored metabolic flux...

Background: Dual plane breast augmentation is a technical variation of the submuscular plane described as a technique that reduces contour deformities due to contraction of the pectoralis major muscle and lower risk of double-bubble deformity associated with breast ptosis. Despite improvement in the aesthetic aspect, there is still no consensus whether this technique affects the function of the pectoralis major muscle. Objectives: The aim of this study was to correlate functional with volumetric changes associated with dissection of the muscle origin in submuscular breast augmentation...

BACKGROUND: Increasing number of patients with preexisting breast implants desire breast conservation therapy for breast cancer. There is paucity of comparative data on tumor margins and re-excisions in these patients. High re-excision rates up to 25% have been reported in breast conservation therapy patients; efforts to obtain cosmesis and avoid implant rupture might increase this further. We analyzed tumor margins, re-excision rates, and recurrence in previously augmented versus non-augmented patients undergoing lumpectomy for breast cancer...

REVIEW
Johannes Gossner
Capsular contracture or capsular fibrosis is the most common complication following breast augmentation with implants. Sonography is usually the initial imaging test performed to examine a suspicious implant. In contrast to the large number of patients developing capsular fibrosis there is only sparse literature reporting about sonographic findings. In this letter after a brief review of normal sonographic findings after breast augmentation, established ultrasound findings suggestive of capsular fibrosis (deformity, increased number of radial folds and thickening of the fibrous capsule) are discussed...

BACKGROUND: Breast augmentation is among the most frequently performed cosmetic plastic surgeries. Providing patients with "realistic" 3D simulations of breast augmentation outcomes is becoming increasingly common. Until recently, such programs were costly and required significant equipment, training, and office space. New simple user-friendly cloud-based programs have been developed, but to date there remains a paucity of objective evidence comparing these 3D simulations with the post-operative outcomes...

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...

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...

PURPOSE: Review of dose metrics as part of the routine evaluation of CT protocols has become commonplace and is required by the Joint Commission and the American College of Radiology for accreditation. Most CT quality assurance programs include a review of CTDIvol and/or SSDE, both of which are affected by changes in mAs and kV. mAs, and sometimes kV, are largely determined by the Tube Current Modulation (TCM) functions of the scanner. TCM, in turn, relies on localizer scans to provide an accurate estimate of patient size...

BACKGROUND: Bra sizing is a common method to preoperatively select implants for breast augmentation; however, no series has analyzed the accuracy of this modality postoperatively. Alternatively, previous investigations have validated the accuracy and utility of three-dimensional (3D) imaging for preoperative simulation in breast augmentation. OBJECTIVES: This investigation utilizes 3D analysis to determine if preoperative bra sizing provides equivocal information compared to surgical 3D simulation for patient education and planning prior to a breast augmentation...

PURPOSE: Develop a computer-aided detection (CAD) system for masses in digital breast tomosynthesis (DBT) volume using a deep convolutional neural network (DCNN) with transfer learning from mammograms. METHODS: A data set containing 2282 digitized film and digital mammograms and 324 DBT volumes were collected with IRB approval. The mass of interest on the images was marked by an experienced breast radiologist as reference standard. The data set was partitioned into a training set (2282 mammograms with 2461 masses and 230 DBT views with 228 masses) and an independent test set (94 DBT views with 89 masses)...

Siliconoma from ruptured breast implants has been reported in multiple body sites, including but not limited to the breast parenchyma, axillary lymph nodes, upper arm, and even lower leg. In this regard, we report a rare case of distant silicone migration to the lower extremities after traumatic breast implant rupture. A 55-year-old Asian woman who received bilateral augmentation mammoplasty 20 years ago presented with ruptured breast implants from a car accident 2 years earlier. Magnetic resonance imaging confirmed intracapsular and extracapsular rupture of the right breast implant, showing "linguine sign...
