Purpose: Cadaveric studies have shown that deficiency of the posterior horn of the medial meniscus (PHMM) increases strain on the anterior cruciate ligament (ACL) graft. However, its influence on the clinical and radiological outcome after ACL reconstruction is less discussed and hence evaluated in this study. Materials and Methods: This study included 77 cases of ACL reconstruction with a minimum 18-month follow-up. Of the 77 cases, 41 patients with intact menisci were compared clinically and radiologically with 36 patients with an injury to the PHMM that required various grades of meniscectomy...

For the analysis of massive samples containing multiple analytes, the enhancement of detection efficiency is crucial. In this study, a facile method was developed for sequential detection of chloramphenicol (CAP) and gentamicin (GEN) in complex samples, e.g. milk, using a surface plasmon resonance (SPR)-based biosensor. Based on the immune inhibition format, two conjugates of antigen and bovine serum albumin (BSA)-denoted as CAP-BSA and GEN-BSA-were grafted on the same channel of the SPR sensor chip. Two standard curves for CAP and GEN were separately obtained by first mixing a single antibody with different concentrations of the relevant antigen...

PURPOSE: Maxillary sinus augmentation via crestal approach has been advocated as an alternative approach for sinus membrane elevation. Presently, no study has examined the relationship between the amount of bone grafting material placed and the final sinus membrane elevation height. Therefore, the present study was aimed at investigating the extent of sinus membrane elevation height depending on the amount of bone grafting material inserted as well as three-dimensionally assessing the likelihood of membrane perforation during membrane elevation...

Aldehyde dehydrogenase (ALDH) is an enzyme that plays an important role in retinoid metabolism and highly expressed in stem cells. This study isolated ALDH-expressing cells from subcutaneous adipose tissue and investigated their potential to enhance healing in a full-thickness skin wound in rats by co-implanting them with collagen-glycosaminoglycan (c-GAG) scaffolds. ALDH-positive cells were isolated by a fluorescence-activated cell sorting technique from Lewis rat's stromal-vascular-fraction (SVF) and transplanted with c-GAG scaffolds in a rat full-thickness skin wound model...

REVIEW
Tobias Bollhorst, Kurosch Rezwan, Michael Maas
Utilizing colloidal particles for the assembly of the shell of nano- and microcapsules holds great promise for the tailor-made design of new functional materials. Increasing research efforts are devoted to the synthesis of such colloidal capsules, by which the integration of modular building blocks with distinct physical, chemical, or morphological characteristics in a capsule's shell can result in novel properties, not present in previous encapsulation structures. This review will provide a comprehensive overview of the synthesis strategies and the progress made so far of bringing nano- and microcapsules with shells of densely packed colloidal particles closer to application in fields such as chemical engineering, materials science, or pharmaceutical and life science...

INTRODUCTION: As the take rate of cultured epidermal autografts in burn wound treatment is variable, widely expanded meshed auto skin grafts are often used in combination with cultured epidermal autograft to increase the take rate and achieve definitive wound coverage. However, a long time (3-4 weeks) required to prepare a cultured epidermis sheet is a disadvantage. Allogeneic cultured epidermis can be prepared in advance and cryopreserved to be used in combination with auto meshed skin grafts for treating third-degree burns...

BACKGROUND: Polyomavirus-associated nephropathy (PVAN) following BK virus reactivation in kidney transplant recipients (KTR) can compromise graft survival. Lowering immunosuppression is the only established approach to prevent or treat PVAN but nonspecifically increasing host immune competence also augments rejection risk. Ex vivo T cell stimulation/expansion offers the possibility to generate BK-specific T cell lines for adoptive immunotherapy. The objective of this study was to develop and characterize a clinical scale protocol to generate BK-specific T cell lines from viremic KTR...

BACKGROUND: The ongoing shortage of donor livers for transplantation and the increased use of marginal livers necessitate the development of accurate pretransplant tests of viability. Considering the importance energy status during transplantation, we aimed to correlate peritransplant energy cofactors to posttransplant outcome and subsequently model this in an ex vivo setting. METHODS: Sequential biopsies were taken from 19 donor livers postpreservation, as well as 30 min after portal venous (PVR) and hepatic arterial reperfusion (HAR) and analyzed by LC-MS for energetic cofactors (ATP/ADP/AMP, NADH/NAD, NADPH/NADP, FAD, GSSG/GSH)...

The nasal valve area is the functional area that allows airflow regulation. It could be divided in an internal area and an external one, basing on the anatomical landmarks. Many conditions can damage these areas with a consequently nasal obstruction, more often in particular extended rhinoplasty and sequels of facial trauma. To restore this area many techniques were advocated during the last decades.In this article the authors investigate on valve areas deficiency in sequel of rhinoplasty proposing a structural approach through alar batten grafts to correct internal-external nasal valves collapse...

A brain-dead donor experienced repeated cardiac arrests followed by severe hypotension requiring multiple vasoactive agents. These events were associated with severe lactic acidosis and dysregulated kidney function in the donor. A 10-hour treatment with extracorporeal membranous oxygenation was instituted, which was able to hemodynamically stabilize the donor. This treatment protocol resulted in the procurement of 2 viable kidney grafts transplanted into 2 recipients, who had immediate kidney graft function and excellent serum creatinine levels upon hospital discharge...

OBJECTIVES: Successful kidney transplant depends partly on the normal physiologic functioning of the bladder, which involves effective urine storage and emptying. The bladder may become abnormal owing to various urologic and neuropathic disorders. Patients with abnormal bladders need careful management before and after transplant. In this study, we aimed to determine the outcomes of renal transplants in relation to various causes of abnormal bladder. MATERIALS AND METHODS: We conducted a retrospective review of 25 patients with abnormal bladder who received 30 renal transplants between 1990 and 2014...
