PURPOSE: To realistically map the electric fields of biological tissues using a diffusion tensor magnetic resonance electrical impedance tomography (DT-MREIT) method to estimate tissue response during electrical stimulation. METHODS: Imaging experiments were performed using chunks of bovine muscle. Two silver wire electrodes were positioned inside the muscle tissue for electrical stimulation. Electric pulses were applied with a 100-V amplitude and 100-μs width using a voltage stimulator...

M13 and other members of the Ff class of filamentous bacteriophages have been extensively employed in myriad applications. The Ph.D. series of phage-displayed peptide libraries were constructed from the M13-based vector M13KE. As a direct descendent of M13mp19, M13KE contains the lacZα insert in the intergenic region between genes IV and II, where it interrupts the replication enhancer of the (+) strand origin. Phage carrying this 816-nucleotide insert are viable, but propagate in E. coli at a reduced rate compared to wild-type M13 phage, presumably due to a replication defect caused by the insert...

Liang Zeng, Jing Lin, Liping Huang
Because the time reversal operator of Lamb waves varies with frequency in composite structures, the reconstructed signal deviates from the input signal even in undamaged cases. The damage index captures the discrepancy between the two signals without differentiating the effects of time reversal operator from those of damage. This results in the risk of false alarm. To solve this issue, a modified time reversal method (MTRM) is proposed. In this method, the frequency dependence of the time reversal operator is compensated by two steps...

BACKGROUND: Obesity and higher body mass index may be associated with higher rates of wound healing complications and hernia recurrence rates following complex abdominal wall reconstruction. The authors hypothesized that higher body mass indexes result in higher rates of postoperative wound healing complications but similar rates of hernia recurrence in abdominal wall reconstruction patients. METHODS: The authors included 511 consecutive patients who underwent abdominal wall reconstruction with underlay mesh...

BACKGROUND: The various approaches to reduction and fixation of isolated displaced zygomatic arch fractures have not been well studied. The authors compared established treatment methods for zygomatic arch fractures for both aesthetic and functional outcomes. METHODS: Consecutive patients with isolated zygomatic arch fractures with a minimum of 6 months' follow-up were studied in five groups: group 1, intraoral approach (no fixation); group 2, temporal approach (no fixation); group 3, coronal flap plate fixation; group 4, external splint fixation; and group 5, no surgery...

BACKGROUND: Reconstruction of external ear is important for the child/adult with craniofacial deformities to achieve balance and harmony of the face and head. The aim of this study was to investigate the clinical application of an expanded two-flap method for auricular reconstruction in hemifacial microsomia. METHODS: Between January of 2014 and November of 2015, 111 hemifacial microsomia patients with microtia underwent auricular reconstruction with an expanded two-flap method...

BACKGROUND: Postoperative resorption of vascularized bone grafts jeopardizes the success of dental implant(s) and functional rehabilitation of the jaw. Recent evidence supports the crucial role of innervation in bone regeneration and turnover. METHODS: This study reports a new technique for simultaneous innervation of vascularized iliac flaps in mandibular reconstruction, through neurorrhaphy between ilioinguinal nerves, which innervate iliac bone, and inferior alveolar nerves or great auricular nerves...

BACKGROUND: The limitations of autologous and alloplastic reconstruction for craniofacial bone defects have created a clinical need for viable tissue-engineering strategies. Recombinant human bone morphogenetic protein-2 (rhBMP-2) has shown promise in this setting. The aim of this study was to determine the long-term biomechanical properties of rhBMP-2-mediated calvarial reconstruction. METHODS: Twelve-week-old New Zealand White rabbits underwent subtotal calvarectomy...

BACKGROUND: Breast augmentation surgery poses many challenges, and meeting the patient's expectations is one of the most important. Previous reports equate 100 cc to a one-cup-size increase; however, no studies have confirmed this between commercially available bras. The aim of this study was to identify the volume increase between cup sizes across different brands and the relationship with implant selection. METHODS: Five bra cup sizes from three different companies were analyzed for their volume capacity...

BACKGROUND: Enhanced recovery following surgery can be achieved through the introduction of evidence-based perioperative maneuvers. This review aims to present a consensus for optimal perioperative management of patients undergoing breast reconstructive surgery and to provide evidence-based recommendations for an enhanced perioperative protocol. METHODS: A systematic review of meta-analyses, randomized controlled trials, and large prospective cohorts was conducted for each protocol element...

BACKGROUND: The BREAST-Q is a patient-reported outcome instrument used to evaluate outcomes in patients undergoing breast cancer surgery and reconstruction. Normative values for the BREAST-Q breast cancer modules have not been established, limiting data interpretation. METHODS: Participants were recruited by means of the Army of Women, an online community of women (with and without breast cancer), to complete Mastectomy, Breast Conserving Therapy, and Reconstruction preoperative BREAST-Q scales...

BACKGROUND: Since the 2012 approval of shaped implants, their use in breast reconstruction has increased in the United States. However, large-scale comparisons of complications and patient-reported outcomes are lacking. The authors endeavored to compare surgical and patient-reported outcomes across implant types. METHODS: The Mastectomy Reconstruction Outcomes Consortium database was queried for expander/implant reconstructions with at least 1-year postexchange follow-up (mean, 18...

BACKGROUND: This national prospective cohort study compared the patient-reported outcomes of breast cancer patients undergoing postmastectomy autologous reconstruction to those who had breast implants, in terms of aesthetic appearance; levels of psychological, physical, and sexual well-being; and overall satisfaction. METHODS: Of 5063 women who underwent immediate reconstruction (n = 3349) or delayed reconstruction (n = 1714) between January 1, 2008, and March 31, 2009, in England, 2923 women who gave informed consent were sent validated, procedure-specific, 18-month follow-up questionnaires...

BACKGROUND: Several new rehabilitation modalities have been proposed after anterior cruciate ligament (ACL) reconstruction. Among these, trigger point dry needling (TrP-DN) might be useful in the treatment of myofascial pain syndrome associated with ACL reconstruction to reduce pain intensity, increase knee flexion range and modify the mechanical properties of the quadriceps muscle during late-stage rehabilitation. To date, this is the first randomized clinical trial to support the use of TrP-DN in the early rehabilitation process after ACL reconstruction...

PET iterative reconstruction algorithms with resolution modelling (RM) can be used to improve spatial resolution in the images. However, RM has a significant impact on quantification, which raises issues for harmonization across multicentre networks or collaborations. This investigation compared quantification from two modern time-of-flight (TOF) PET/CT systems from different manufacturers with RM with the intention to harmonize recovery. Images of a National Electrical Manufacturers Association image quality phantom with a sphere-to-background concentration ratio of 4 : 1 were acquired on a GE Discovery 710 and a Siemens Biograph mCT and reconstructed with RM and TOF...

PURPOSE: This article describes the digitoclastic technique, an innovative procedure for coronal displacement of the lingual flap. The new technique has the potential to obtain primary flap closure without surgical risks to the anatomical structures on the lingual side of the mandible. MATERIALS AND METHODS: Reconstruction of an atrophic mandible with guided tissue regeneration (guided bone regeneration) and implant placement is described, using the digitoclastic technique to displace the lingual flap coronally...
