Textile effluent consists of enormous quantities of toxic dyes, which are being discharged into natural aqueous system and thus contaminate the water quality. Hence it is important to develop an eco-friendly and cost effective technology to treat the dyes contaminated wastewater. In this research, an integrated approach of electrochemical oxidation (EO) and biodegradation process (BP) was studied of methyl red (MR) dye. In EO, RuO2-IrO2-TiO2 is used as anode and titanium mesh electrode as cathode. This was followed by BP of the treated EO effluent...

Computer-aided detection systems play an important role for the detection of breast abnormalities using mammograms. Global segmentation of mass in mammograms is a complex process due to low contrast mammogram images, irregular shape of mass, speculated margins, and the presence of intensity variations of pixels. This work presents a new approach for mass detection in mammograms, which is based on the variational level set function. Mesh-free based radial basis function (RBF) collocation approach is employed for the evolution of level set function for segmentation of breast as well as suspicious mass region...

Graphene, a honeycomb sp(2) hybridized carbon lattice, is a promising building block for hybrid-nanomaterials due to its electrical, mechanical, and optical properties. Graphene can be readily obtained through mechanical exfoliation, solution-based deposition of reduced graphene oxide (rGO), and chemical vapor deposition (CVD). The resulting graphene films' topology is two-dimensional (2D) surface. Recently a three-dimensional (3D) graphene topology has been demonstrated by various approaches. However, the resulting graphene films are lying flat on the surface hence still exposing a 2D surface topology...

BACKGROUND: Vertical bone augmentation (VBA) remains unpredictable and challenging for most clinicians. This study was aimed to compare hard tissue outcomes of VBA, with and without rhBMP-2, under space-making titanium mesh in a canine model. METHODS: Eleven male beagle dogs were used in the study. Experimental ridge defects were created to form atrophic ridges. VBA was performed via guide bone regeneration (GBR) using titanium mesh and allografts. In experimental hemimandibles, rhBMP-2/ACS was well mixed with allografts prior to procedures, whereas a control buffer was applied within controls...

Recently, adipose tissue has been regenerated by combining scaffolds, growth factors, and/or adipose tissue-derived stromal cells (ASCs). However, the safety of growth factors and ASCs has not been confirmed in cancer patients. We reported the regeneration of adipose tissue in the internal space of a polypropylene mesh containing a collagen sponge (CS), without using any growth factors or cells. We herein explored the formation of adipose tissue, using the bioabsorbable implant containing CS, in rats. We prepared the implants without and with CS, using threads of either poly l-lactide-co-ε-caprolactone [P(LA/CL)] or poly-l-lactic acid (PLLA), and measured their strengths...

In contrast to "classical" forms of Osteogenesis imperfecta (OI) types I to IV, caused by a mutation in COL1A1/A2, OI type V is due to a gain-of-function mutation in the IFITM5 gene, encoding the interferon-induced transmembrane protein 5, or bone-restricted ifitm-like protein (BRIL). Its phenotype distinctly differs from OI types I to IV by absence of blue sclerae and dentinogenesis imperfecta, by the occurrence of ossification disorders like hyperplastic callus and forearm interosseous membrane ossification...

Anil Sharma, Priyank Chelawat
Hernia repair techniques vary greatly depending upon the setting, surgeons, insurance reimbursement systems, resources, and logistical capabilities. Open mesh repair is the most frequently used technique. Choosing the best technique for inguinal hernia repair is a challenge. There is no single technique to manage every type of hernia. Today, laparoscopy and robotics are at the forefront of advanced surgical tools and offer a range of options for general surgeons who are critically evaluating new procedures...

REVIEW
George Pei Cheung Yang
Laparoscopic repair for ventral and incisional hernias was first reported in the early 1990s. It uses intraperitoneal only mesh placement to achieve a tension-free repair of the hernia. However, in recent years, there has been greater concern about long-term complication involving intraperitoneal mesh placement. Many case reports and case series have found evidence of mesh adhesion, mesh fistulation, and mesh migration into hollow organs including the esophagus, small bowel, and large bowel, resulting in various major acute abdominal events...

The working gas turbine blades are exposed to the environment of high temperature, especially in the leading-edge region. The mist/air two-phase impingement cooling has been adopted to enhance the heat transfer on blade surfaces and investigate the leading-edge cooling effectiveness. An Euler-Lagrange particle tracking method is used to simulate the two-phase impingement cooling on the blade leading-edge. The mesh dependency test has been carried out and the numerical method is validated based on the available experimental data of mist/air cooling with jet impingement on a concave surface...

Myunggi An, Haipeng Liu
Amphiphilic vaccine based on lipid-polymer conjugates is a new type of vaccine capable of self-delivering to the immune system. When injected subcutaneously, amphiphilic vaccines efficiently target antigen presenting cells in the lymph nodes (LNs) via a unique albumin-mediated transport and uptake mechanism and induce potent humoral and cellular immune responses. However, whether this new type of vaccine can be administrated via a safe, convenient microneedle-based transdermal approach remains unstudied. For such skin barrier-disruption systems, a simple application of microneedle arrays (MNs) is desired to disrupt the stratum corneum, and for rapid and pain-free self-administration of vaccines into the skin, the anatomic place permeates with an intricate mesh of lymphatic vessels draining to LNs...

For treatments requiring split-thickness skin grafts, it is preferable to mesh the grafts. This reduces the amount of excised skin and covers more wound area. The mesh technique, however, destroys surface continuity, which results in scarring. Strain-based bioreactors, on the other hand, have successfully expanded split-thickness skin grafts in vitro within a 7-day period, increasing graft coverage. After in vitro expansion, the expanded skin grafts were tested in a porcine full-thickness excisional wound model...

We present a self-assembled template of tetraphenylmethane-based variants on a Au(111) surface which feature a periodic lateral arrangement of acetyl groups sticking out of the molecular film. Using the tip of a scanning tunneling microscope, this acetyl group can be removed in a spatially controlled way without a significant effect on the remaining molecular assembly. The chemically modified molecule can readily be distinguished from the original ones such that information can be engraved in the molecular film...
