Acceptance of Cosmetic Surgery: Body Image, Self Esteem and Conformity

AbstractCosmetic surgery is the most prevalent of surgeries in Iran. This multidimensional concept depends on many factors. The aim of this study is an investigation of the relationship between body-image, self-esteem, conformity with cosmetic surgery. 290 individuals who were applying for Cosmetic Surgery completed an inventory of scales comprising ACSS, RSE, BIS, CS and demographics. The results showed women were more likely than men. Individuals in the age range (18 to 20) had the most cosmetic surgery. Positive body image and conformity predict acceptance of cosmetic surgery but self-esteem don’t. Self-esteem indirectly effect on cosmetic surgery

Diffusion tensor tractograghy can affect treatment strategy to remove brain occupying mass lesions

Radical resection of a pathological lesion along with the preservation of eloquent cerebral tissue is the principle goal of neurosurgery. Brain lesions are usually diagnosed by conventional magnetic resonance imaging (MRI), but this method is unable to describe the relationship between lesions and neighboring specific white matter (WM) tracts. Diffusion tensor tractograghy (DTT) is a new sophisticated imaging modality to reveal the neural fibers and their relationships with lesions. In the current study we assess that how diffusion tensor tractograghy can affect on treatment planning in patients afflicted by different types of brain lesions. In this prospective observational study, eight patients with brain mass lesion underwent conventional brain MRI pulse sequences and DTT imaging with 1.5 Tesla system using 64 independent diffusion encoding directions between December 2011 to January 2013.Acquired images were assessed by the neuroradiologist and neurosurgeon. Finally, the treatment strategies were compared using data before and after the tractograghy. The treatment strategy in six patients changed from radiotherapy into the craniotomy by using tractograghy data, in one patient changed from radio surgery to craniotomy and in one patient, neurosurgeon preferred to avoid operation. As we can infer from this study, based on the tractograghy results, the treatment technique may be changed, and the treatment plan could be devised with more accuracy and in case of surgery, may lead to less post-operative neurological deficits and better outcome results

Incorporation of curcumin into collagen-multiwalled carbon nanotubes nanocomposite scaffold: an in vitro and in vivo study

Aim: Fabrication of biological substitutes to regenerate damaged tissues or organs is one of the main aims of tissue engineering (TE). In this context, the goal of this study was to fabricate a scaffold that mimicked the structure and functions of the extracellular matrix (ECM) of the native tissues. Towards this aim, a novel biomimetic three-dimensional (3D) scaffold containing collagen (COL), multi-walled carbon nanotubes (MWCNTs), and curcumin (CUR) was created using the freeze-drying technique. Materials and methods: Scaffolds were prepared by adding 0.5–1.5% MWCNTs and 5–15% CUR to pure COL solutions, followed by freeze-drying. Physical and chemical characterizations of the scaffolds were evaluated by a universal testing machine, scanning electron microscope (SEM), fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). Biological studies were mainly focused on in-vitro bioactivity, biodegradability, CUR release, and in-vitro and in vivo biocompatibility using mesenchymal stem cells (MSCs) and rat animal models. Results: FTIR and XRD confirmed the presence of MWCNTs and CUR in the COL scaffolds, while SEM revealed highly interconnected porous morphology. Moreover, the addition of up to 1% MWCNTs and 10% CUR enhanced tensile strength from 5 MPa to 19 MPa. The developed COL-MWCNTs 1%-CUR 10% composite scaffolds revealed excellent surface wettability, in vitro bioactivity, and in vitro biocompatibility using rat synovial-derived MSCs (SM-MSCs). Importantly, the in vivo study revealed reduced inflammatory response in the rat animal model after six weeks of implantation, which could be attributed to the promising in vitro biodegradability and release of CUR. Conclusion: The newly developed COL-MWCNTs 1%-CUR 10% freeze-dried scaffolds have demonstrated their high potential for TE applications

Determination of intra-axial brain tumors cellularity through the analysis of T2 Relaxation time of brain tumors before surgery using MATLAB software

Introduction: Timely diagnosis of brain tumors could considerably affect the process of patient treatment. To do so, para-clinical methods, particularly MRI, cannot be ignored. MRI has so far answered significant questions regarding tumor characteristics, as well as helping neurosurgeons. In order to detect the tumor cellularity, neuro- surgeons currently have to sample specimens by biopsy and then send them to the pathology unit. The aim of this study is to determine the tumor cellularity in the brain. Methods: In this cross-sectional study, 32 patients (18 males and 14 females from 18-77 y/o) were admitted to the neurosurgery department of Shohada-E Tajrish Hospital in Tehran, Iran from April 2012 to February 2014. In addition to routine pulse sequences, T2W Multi echo pulse sequences were taken and the images were analyzed using the MATLAB software to determine the brain tumor cellularity, compared with the biopsy Results: These findings illustrate the need for more T2 relaxation time decreases, the higher classes of tumors will stand out in the designed table. In this study, the results show T2 relaxation time with a 85% diagnostic weight, compared with the biopsy, to determine the brain tumor cellularity (p<0.05). Conclusion: Our results indicate that the T2 relaxation time feature is the best method to distinguish and present the degree of intra-axial brain tumors cellularity (85% accuracy compared to biopsy). The use of more data is recommended in order to increase the percent accuracy of this techniques
