Intense pulsed light (IPL) has been used to treat postinflammatory hyperpigmentation and telangiectasia in Fitzpatrick type I -II skin. However, its therapeutic effects after superficial second-degree burns in Asian populations with Fitzpatrick type III-IV skin are uncertain. Thirty-five Han Chinese patients with facial or hand hyperpigmentation and telangiectasia due to second-degree fire burns received treatment with IPL. Each patient underwent 2-6 treatments over 3-5 weeks. The laser wavelength was 560-615 nm...

Plastics have been one of the highly valued materials and it plays an significant role in human's life such as in food packaging and biomedical applications. Bioplastic materials can gradually work as a substitute for various materials based on fossil oil. The issue like sustainability and environmental challenges which occur due to manufacturing and disposal of synthetic plastics can be conquering by bio-based plastics. Feathers are among the most inexpensive abundant, and renewable protein sources. Feathers disposal to the landfills leads to environmental pollutions and it results into wastage of 90% of protein raw material...

Cultured epithelial autografts (CEA) with highly expanded mesh skin grafts were used for extensive adult burns covering more than 30% of the total body surface area. A prospective study on eight patients assessed subjective and objective findings up to a 12-month follow-up. The results of wound healing for over 1:6 mesh plus CEA, gap 1:6 mesh plus CEA, and 1:3 mesh were compared at 3, 6, and 12 months using extensibility, viscoelasticity, color, and transepidermal water loss by a generalized estimating equation (GEE) or generalized linear mixed model (GLMM)...

Yttrium-90-Ibritumomab Tiuxetan (Zevalin®) is used in the treatment of non- Hodgkin's lymphoma. Extravasation is an iatrogenic complication that is fortunately rare. However, the treatment of this complication is often complex due to the risk of extensive skin necrosis and unpredictable evolution of localized irradiation. This vesicant drug requires emergency management when extravasation occured. Radiations burns have specificities. Therefore, wound coverage involves specific plastic surgical techniques. Here, we report the case of a man presenting a chronic and extensive skin necrosis of upper arm treated with an antero-lateral thigh free flap...

Size distribution, water-soluble inorganic ions (WSII), and organic carbon (OC) and elemental carbon (EC) in size-segregated aerosols were investigated during a year-long sampling in 2010 over New Delhi. Among different size fractions of PM10, PM0.95 was the dominant fraction (45%) followed by PM3-7.2 (20%), PM7.2-10 (15%), PM0.95-1.5 (10%), and PM1.5-3 (10%). All size fractions exceeded the ambient air quality standards of India for PM2.5. Annual average mass size distributions of ions were specific to size and ion(s); Ca2+, Mg2+, K+, NO3-, and Cl- followed bimodal distribution while SO42- and NH4+ ions showed one mode in PM0...

Experiments are conducted to measure the resistance experienced by light cylinders rolling over flat beds of granular media. Sand and glass spheres are used for the beds. The trajectories of the rolling cylinders are determined through optical tracking, and velocity and acceleration data are inferred through fits to these trajectories. The rolling resistance is dominated by a velocity-independent component, but a velocity-dependent drag exceeding the expected strength of air drag is also observed. The results are compared to a theoretical model based on a cohesionless Mohr-Coulomb rheology for a granular medium in the presence of gravity...

Growth of informal electronic waste (e-waste) recycling sector is an emerging problem for India. The presence of halogenated compounds in e-wastes may result in the formation of persistent organic pollutants like polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) during recycling processes. We therefore investigated PCBs and PCDD/Fs in surface soils explicitly from the informal e-waste recycling sites and nearby open dumpsites of major metropolitan cities from four corners of India, viz...

China's intensive agriculture has led to a broad range of adverse impacts upon ecosystems and thereby caused environmental quality degradation. One of the fundamental problems that face land managers when dealing with agricultural nonpoint source (NPS) pollution is to quantitatively assess the NPS pollution loads from different sources at a national scale. In this study, export scenarios and geo-spatial data were used to calculate the agricultural NPS pollution loads of nutrient, pesticide, plastic film residue, and crop straw burning in China...

BACKGROUND: Plastic surgery as a discipline is poorly understood by many, including primary care physicians, nurses, medical students, and the public. These misconceptions affect the specialty in a number of ways, including referral patterns and recruitment of medical students into residency programs. The reason for these commonly held misconceptions has not yet been addressed in the plastic surgery literature. As such, we assessed medical students' knowledge and perceptions of plastic surgery as a discipline and explored factors influencing these opinions...

Lipotransfer for soft tissue filling is a well-established plastic and aesthetic surgical technique. Elective fat grafting is considered a safe and well-tolerated procedure. Coleman and others have reported that fat grafting may have tissue regenerative properties and not only serve as a soft tissue filler. There have been reports from our group and others that it may improve fibrosis secondary to many different pathological aetiologies including scleroderma, burn injury, lichen sclerosis, graft vs host disease, and radiation...

May the force be with you: Xia, Burns, Martinez, and co-workers harnessed the ring strain of ladderenes to enable both their polymerization and mechanochemical unzipping to yield semiconducting polyacetylene-based block copolymers. These materials have promise as functional polymers for applications such as detection of physical stress.

Ventriculoperitoneal (VP) shunt placement is among the most common surgical procedures undertaken by neurosurgeons. Complications arising from the thoracic portion of the shunt are relatively rare in comparison with those of the intraventricular and peritoneal portions. Disruption of primary breast development following VP shunt placement has not previously been reported. The authors describe the case of a 15-year-old girl referred to the plastic surgery department with a significant right breast deformity and associated asymmetry following VP shunt placement performed during the neonatal period...
