The graft of autologous fat for the augmentation of soft tissue is a common practice frequently used in the field of plastic and reconstructive surgery. In addition, the presence of adipose derived stem cells (ASCs) in adipose tissue stimulates the regeneration of tissue in which it is applied after the autologous fat grafting improving the final clinical results. Due to these characteristics, there is an increasing interest in the use of ASCs for the treatment of several clinical conditions. As a consequence, the use of clean room environment is required for the production of cell-based therapies...

Bisphenol analogues are a group of chemicals which are being widely applied in industrial and household products owing to regulations on bisphenol A (BPA) in many countries. In this study, an analytical method, including extraction from complex environmental matrices, clean-up using solid phase extraction (SPE) and following-up derivatization prior to gas chromatography coupled with mass spectrometry (GC-MS), was developed to analyze seven commonly used bisphenols in sediment. Five kinds of extraction solvents, four kinds of SPE cartridges, and four kinds of SPE eluting solvents were individually tested for their performances; and the conditions for derivatizing were also optimized...

Operating room (OR) turnaround time (TAT) is the minimal essential time required for cleaning of OR and preparation for the next case. The TAT inversely affects OR efficiency. Several factors related to personnel, equipment and scheduling have been identified as causes of increased TAT. We conducted the study to identify factors that affect OR TAT and to propose recommendations for its reduction. The retrospective study, conducted at Aga Khan University Hospital, Karachi, comprised TAT records related to March 2014...

Autologous and allogeneic stem cell transplantation (SCT) represents a therapeutic option widely used for hematopoietic malignancies. One important milestone in the development of this treatment strategy was the development of effective cryopreservation technologies resulting in a high quality with respect to cell viability as well as lack of contamination of the graft.Stem cell preparations have been initially performed within standard laboratories as it is routinely still the case in many countries. With the emergence of cleanrooms, manufacturing of stem cell preparations within these facilities has become a new standard mandatory in Europe...

INTRODUCTION: Cell-phones are the typical kind of object brought into the operating room from outside by hospital staff. A great effort is made to reduce the level of potentially contaminating bacteria in the operating room, and introducing these devices may run counter to good practice. The study hypothesis was that cell-phones are colonized by several strains of bacteria and may constitute a source of nosocomial contamination. The main study objective was to screen for bacterial colonies on the surfaces of cell-phones introduced in an orthopedic surgery room...

Microfluidics has found increasingly wide usage in the research and teaching laboratory, but setting up a facility for its production has typically required either significant capital expense or sacrifice of quality. We present an approach to produce devices, without a clean room, using LEDs and spin-coaters, and plasma bonded using a commercial microwave oven. Submicron features can be readily reproduced with good fidelity.

Emma Rose turned 5 yesterday. She is the definition of spunky, sass and spice. Gives her parents a run for the money every time she's asked to clean up her room, be good to her sister and put on a pair of shoes. Nothing is simple - she is just too fierce for that. And that passion presents a great challenge, and presents a great gift. This article is protected by copyright. All rights reserved.

Indoor environments, where people spend most of their time, are characterized by a specific microbial community, the indoor microbiome. Most indoor environments are connected to the natural environment by high ventilation, but some habitats are more confined: intensive care units, operating rooms, cleanrooms and the international space station (ISS) are extraordinary living and working areas for humans, with a limited exchange with the environment. The purposes for confinement are different: a patient has to be protected from infections (intensive care unit, operating room), product quality has to be assured (cleanrooms), or confinement is necessary due to extreme, health-threatening outer conditions, as on the ISS...

BACKGROUND: The treatment of severe full-thickness skin defects represents a significant and common clinical problem worldwide. A bio-engineered autologous skin substitute would significantly reduce the problems observed with today's gold standard. METHODS: Within 15 years of research, the Tissue Biology Research Unit of the University Children's Hospital Zurich has developed autologous tissue-engineered skin grafts based on collagen type I hydrogels. Those products are considered as advanced therapy medicinal products (ATMPs) and are routinely produced for clinical trials in a clean room facility following the guidelines for good manufacturing practice (GMP)...

Two highly porous Co-based metal-azolate frameworks (MAFs), MAF-5(Co) and MAF-6(Co), which are isostructural with MAF-5(Zn) and MAF-6(Zn), respectively, were first synthesized in high yield and purity at room temperature. The syntheses compared two mixing methods, slow and fast, using cobalt acetate as the metal ion (Co(2+)) source and 2-ethylimidazole as the ligand. Triethylamine was applied as an additive/promoter in aqueous/ethanol solutions, and benzene and cyclohexane were used as hydrophobic templates...

Intentional oxidation of an As2-decapped (100) In0.57Ga0.43As substrate by additional H2O dosing during initial Al2O3 gate dielectric atomic layer deposition (ALD) increases the interface trap density (Dit), lowers the band edge photoluminescence (PL) intensity, and generates Ga-oxide detected by x-ray photoelectron spectroscopy (XPS). Aberration-corrected high resolution transmission electron microscopy (TEM) reveals formation of an amorphous interfacial layer which is distinct from the Al2O3 dielectric and which is not present without the additional H2O dosing...

Two-dimensional semiconductors with layer thicknesses of a few nanometers to tens of nanometers have attracted tremendous research interest due to their fascinating electrical, optical, and optoelectronic properties and technologically important applications. In this work, two dimensional ternary ZnIn2S4 nanosheets which self-assemble into microflowers have been synthesized through a feasible chemical vapour deposition process. High-resolution transmission electron microscope (HRTEM) analysis reveals that the ZnIn2S4 nanostructure exhibits an extremely high phase purity and a single crystal nature free of dislocations, stacking faults or twins...

Nanodiamonds are the subject of active research for their potential applications in nano-magnetometry, quantum optics, bioimaging and water cleaning processes. Here, we present a novel thermodynamic model that describes a graphite-liquid-diamond route for the synthesis of nanodiamonds. Its robustness is proved via the production of nanodiamonds powders at room-temperature and standard atmospheric pressure by pulsed laser ablation of pyrolytic graphite in water. The aqueous environment provides a confinement mechanism that promotes diamond nucleation and growth, and a biologically compatible medium for suspension of nanodiamonds...
