background: wearing spectacles is the most common approach in correcting the refractive errors worldwide. due to harmful effects of overexposure to solar ultraviolet radiations, the usage of multi-layer coatings in ophthalmic lenses has recently been increased. these lenses can reduce the reflections and hence increase the transmission of visible light; they can also decrease the transmission o...

plastic bronchitis (pb) refers to the presence of inspissated bronchial casts (bc) is uncommon in children.our case presented with subcutaneous emphysema as the dominant manifestation and was suspected to have foreign body in airway, but bronchoscopy revealed a bronchial cast. subcutaneous emphysema as the initial/sole manifestation of plastic bronchitis is very rare in children.

bananas are climacteric fruits and controlling ripening is effective in reducing loss. this experiment studied the effect of packaging (plastic bag, edible wax and plastic bag, plastic bag and 2 or 4 g/kg potassium permanganate) over 5 weeks of cold storage on the quality and characteristics of cavendish cultivar bananas. the samples were removed from storage at 8, 16, 24, 32 and 40 days and fr...

PURPOSE: Academic plastic surgery training depends upon open access to learning reconstructive techniques provided by free vascularized soft tissue coverage. Key components of this approach include recruitment of an accomplished and diverse faculty, broad-based collaboration, patient geographic outreach, and fundamental support from all levels of staff. This study reviews a 10-year experience o...

INTRODUCTION: Recent data suggests 42 percent of surgeons report their patients are seeking aesthetic surgery to improve their appearance on Instagram and other social media.1 Despite the rising influence of Instagram in plastic surgery, few academic publications address Instagram, let alone evaluate its utilization in plastic surgery. We thus set out to systematically answer the following two ...

To validate performance, we compared the new plastic BacT/ALERT (bioMérieux, Durham, NC) SN bottle to the current glass SN bottle with samples of blood obtained for culture from adults and found them comparable for both recovery and speed of detection of microorganisms. We conclude that the safety advantage of plastic bottles can be achieved without compromising performance.

SUMMARY This report examines the meaning of validity and reliability and the role of psychometrics in plastic surgery. Study titles increasingly include the word "valid" to support the authors' claims. Studies by other investigators may be labeled "not validated." Validity simply refers to the ability of a device to measure what it intends to measure. Validity is not an intrinsic test property....

The aim of this paper was to collect currently available data related to the use of stem cells in aesthetic dermatology and plastic surgery based on a systemic review of experimental and clinical applications. We found that the use of stem cells is very promising but the current state of art is still not effective. This situation is connected with not fully known mechanisms of cell interactions...
