There is very little information available on the chemical composition and the quality attributes of the citrus species studied which are truly endangered in Spain. None of the fruits studied is available for commercial purposes, which is the main interest and novelty of this study. The aim of this work was to fully describe the morphology, volatile composition, and sensory profile of traditional citrus fruits: sour lime (SoLi), sweet lime (SwLi), and sweet lemon (SwLe), to have the information to convince farmers and growers to cultivate these fruits again. The predominant sugar was fructose while citric acid prevails in SoLi and SwLe. Regarding volatiles compounds, monoterpenes, monoterpenoids, and esters predominated in the juices, and these three families plus sesquiterpenes in the peels. The juice of SoLi presented the highest content of esters (14.8%), SwLi juice presented similar values of both monoterpenes and monoterpenoids (46.1 and 46.0%, resp.), and SwLe juice had the highest content of monoterpenes (72.2%). The results demonstrated the high potential of these citrus materials for the agrofood industry. Therefore, it will be possible to recover these vegetal materials at risk of disappearing for potential uses by the food industry and simultaneously help maintaining the biodiversity.

Abstract Background Breast cancer is the most common cancer in women and the leading cause of women mortality all over the world. Oncoplastic techniques are replacing SWLE for better cosmetic outcomes and better exposure of the tumor. Objective To assess the round block technique as regard oncological safety, surgical outcomes and patients' satisfaction comparing results with standard wide local excision. Patients and Methods In our study 40 breast cancer patients are subdivided into group (A) 20 females which underwent round block technique and group (B) 20 femaleswhich underwent standard wide local excision. Patient and tumor criteria including age, family history, comorbidities, tumor side and histopathological results were considered to be non-significant between 2 groups so the only difference is the surgical technique. Results The study shows that round block technique has comparable post-operative parameters with less surgical complications and better cosmoses as it is scarless operation without nipple and areola shift suggesting that the round block technique is superior to SWLE in selected cases. Conclusion The round block technique has comparable post-operative parameters with less surgical complications and better cosmoses as it is scarless operation without nipple and areola shift suggesting that the round block technique is superior to SWLE in selected cases.

Abstract Background Breast cancer is the most common cancer in women all over the world representing 18% of all women reported cases of cancer. It represents the leading cause of women mortality as representing 23% of all women cancer deaths. The decision in any breast cancer patient is taken by MDT that includes breast surgery consultant, pathology consultant, plastic surgery consultant, radiology consultant and medical oncology consultant. Breast conserving surgeries are now the standard technique for management of breast cancer patient. Oncoplastic techniques are replacing SWLE for their better cosmetic outcomes and better exposure of the tumor. Objective The aim of this work was to assess the round block technique as regard oncological safety, surgical outcomes and patients' satisfaction comparing results with standard wide local excision. Methods This is a retrospective study to assess the round block technique as an oncological procedure for management of early breast cancer near to nipple-areola complex as regard oncological safety, surgical outcomes and patients' satisfaction comparing results with standard wide local excision. It was conducted at general surgery department, Ain Shams university hospitals. Approval of the Ethical Committee and written informed consent from all participants were obtained. In our study 40 breast cancer patients are subdivided into group (A) 20 females which underwent round block technique and group (B) 20 femaleswhich underwent standard wide local excision. Patient and tumor criteria including age, co morbidities, tumor size and distance between tumor and nipple-areola complex were considered to be nonsignificant between 2 groups so the only difference is the surgical technique. Results The study shows that the round block technique and SWLE have the same results regarding hospital stay, post operative complications and oncological recurrence with the advantage to RBT because of its better cosmetic outcomes. So, the round block technique is superior to SWLE in selected cases. Conclusion The round block technique has comparable post operative parameters with better cosmoses as it is scarless operation without nipple and areola shift suggesting that the round block technique is superior to SWLE in selected cases.

Abstract Background The goal of optimizing the cosmetic and oncologic outcomes of BCS has been addressed in recent years by the emergence of the field of oncoplastic surgery, that originally defined as an assortment of volume replacement techniques performed by plastic surgeons to replace all or part of the resected breast volume with myocutaneous tissue flaps. The definition of oncoplastic surgery has more recently been expanded to include a wide range of volume displacement or volume redistribution procedures performed by breast surgeons and general surgeons to optimize breast shape and breast volume following breast cancer surgery. Aim of the Work To assess the round block technique as regard oncological safety, surgical outcomes and patients' satisfaction comparing results with standard wide local excision. Patients and Methods This is a prospective randomized study to assess the round block technique as an oncological procedure for management of early breast cancer near to nipple-areola complex as regard oncological safety, surgical outcomes and patients' satisfaction comparing results with standard wide local excision. Twenty breast cancer patients are subdivided into group (A) 10 females which underwent round block technique and group (B) 10 femaleswhich underwent standard wide local excision. Patient and tumor criteria including age, co morbidities, tumor size and distance between tumor and nipple-areola complex were considered to be non-significant between 2 groups so the only difference is the surgical technique. Results The round block technique and SWLE have the same results regarding operative time, intra-operative blood loss and post operative complications with the advantage to RBT because of its better cosmetic outcomes and lower re-excision rates. So, the round block technique is superior to SWLE in selected cases. Conclusion The round block technique has comparable operative parameters to SWLE with no evidence of increased surgical complications. With a lower re-excision rates and better cosmoses were observed in the round block patients as it is scarless operation without nipple and areola shift suggesting that the round block technique is superior to SWLE in selected cases.

AbstractHighly efficient single-component white light emitters (SWLEs), are attractive candidates for the simple and cost-effective fabrication of high-performance lighting devices. This study introduced a donor–π–acceptor and a donor–π–donor stilbene-based chromophores, representing pH-responsive fluorescence. The emitters showed yellow and green fluorescence in their neutral form. At the same time, protonation of the chromophores caused blue fluorescence color with a strong hypsochromic shift. The white light emission (WLE) for these chromophores was observed at approximately pH 3 due to the simultaneous presence of the neutral and protonated forms of the chromophores, covering almost all the emission spectra in the visible region (400–700 nm). These chromophores presented exceptional white light quantum yields (Φ) between 31 and 54%, which was desirable for producing white light-emitting devices. Density functional theory (DFT) and time-dependent (TD)-DFT were applied to study the structural and electronic properties of the chromophores.
