In this study, searching for biophotonic crystals in some organisms and plants.Experiments were carried out on Bombyx mori Pupae, Scarabaeus viette Wing, Merlangius merlangus Peel, Domestic pigeon Feathers, Gallus gallus domesticus Feathers, and Bambusa vulgaris (L.) using Scanning Electron Microscope Technique (SEM) and Energy Dispersive X-Ray Spectroscopy (EDX).This study explores the presence and characteristics of biophotonic crystals in various organisms and plants using Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray Spectroscopy (EDX) techniques.The research focuses on six specimens: Bombyx mori (silkworm pupae), Scarabaeus viette (dung beetle wing), Merlangius merlangus (fish peel), Domestic pigeon feathers, Gallus gallus domesticus (chicken feathers), and Bambusa vulgaris (bamboo).The analysis revealed the presence of Chitin in silkworm pupae and dung beetle wings, Guanine in fish peel, Keratin in feathers, and Cellulose in bamboo.These biophotonic crystals contribute to the coloration seen in these specimens, produced not by pigments but by the physical interaction of light with nanostructures.Results showed that these materials contain Chitin, Cellulose (Pupae and bamboo), Guanine, and Keratin respectively.This study through light on a new field of photonic crystals need further researches.This research highlights the diverse roles of photonic crystals in nature, emphasizing the need for further studies to understand their potential applications in optoelectronics and photonics.The findings suggest a new avenue for exploring natural photonic crystals and their possible technological uses.

Introduction:Despite advances in surgical techniques, technology and perioperative care, mortality and morbidity following PD is as high as 5% and 35-60% respectively.POPF, PPH are the leading cause of morbidity and mortality following PD and the prediction of these complications is one of the important aims of post operative care.We aim to determine the role of C-reactive protein in the prediction of POPF and PPH.Methods: Data from patients who underwent pancreaticoduodenectomy from December 2021 to February 2023 was collected.Postoperative day 1 and day 3 CRP assay was done and occurrence of PPH and POPF was recorded.Linear regression analysis and ROC curve were used to derive the results.Results: Among the 46 patients analyzed, 12(26.08%)patients developed PPH and 8(17.39%)developed POPF which included 3(6.52%) CR-POPF and the mortality rate was 4.34%.Mean day 1 and day 3 CRP was 27.464 and 22.938 in patients of PPH with standard coefficients of 0.661 and 0.647 (p=0.001).Mean CRP was 11.718 and 2.153 in POPF on day 1 and day 3, but it was not statistically significant (p=0.152,p= 0.769 respectively).At cut off values of CRP>17.5 mg/dl, the sensitivity and specificity of day 3 CRP in predicting grade C PPH was 86% and 77% (p=0.001).Conclusions: High CRP levels can predict the development of PPH and thereby reduce the morbidity and mortality by early identification of at-risk patients.
