The escalating issue of marine plastic pollution is primarily attributed to the extensive utilization of plastics coupled with their improper disposal in oceans. Microplastics (MPs), particles measuring less than 5 mm, result from the degradation processes of larger plastics, exacerbating ocean pollution. In this research, 100 samples of a carnivorous fish, Alepes vari, from the Chennai coast of Bengal Bay were collected and analyzed for the presence of MPs, which revealed varied accumulation ratios of MPs within their gastrointestinal tract. Through hydrogen peroxide digestion of 100 fish specimens, it was found that approximately 68% contained MPs, with an average abundance of 9.5 (±0.3) particles per individual. The predominant types of MPs observed were pellets (81.34%) and films (18.66%) with brown pellets comprising the majority (25.97%). Further analysis indicated a higher concentration of MPs in the stomach compared to the intestine. Fourier transform infrared radiation analysis- attenuated total reflection confirmed the presence of Polystyrene polymer in the ingested MPs, suggesting a potential link between the dietary habits of these fish and their ingestion of microplastics.

Introduction: The aim of this study was the evaluation of the effect of SCAD training software on shade matching ability of dental students. Materials and Methods: 84 students who passed shade matching topic in their theoritical courses were devided into two groups of case and control. They passed the exam of SCAD software in two steps. Interval of tests was six weeks. The case group unlike the control group get the training of SCAD between these two steps. The data were entered into SPSS software (version 21) to determine the progress of the students ability for shade mathching after training. Results: : In this study the case group showed significant progress in results Their score varied in various tests from the minimum 0. 9 to the maximum 9. 2. According to the results, training effect of the SCAD software method was better than conventional method in Color differentiation in Exact Match 𝜫 /100 (P, 0. 0001) and from statistical point of view it has been improved shade matching ability rather than conventional method as much as 6 score. Also Difference in Matching Pair Total Light & Dark /29 evaluation was statisticaly significant that means after training, SCAD group had less wrong Diagnosis than control group. (P, 0. 001) Conclusion: Training with SCAD software had significant effect on increasing the accuracy of students shade matching abbility.

Introduction: HIV/AIDS is a multisystemic disorder and occurrence of cardiovascular disease is higher compared to non-HIV individuals. Spontaneous coronary artery dissection (SCAD) remains a rare and underdiagnosed cause of acute coronary syndrome (ACS), even in modern day era. SCAD is predominantly seen in young to middle aged females and present as a nonatherosclerotic cause of myocardial ischaemia, infarction or sudden cardiac death (SCD),with or without ventricular arrythmias. Ventricular tachycardia (VT) can sometimes be the initial presentation of SCAD. HIV associated arteriopathy can predispose to occurrence of SCAD. We report a case of a 38-year-old male suffering from HIV/AIDS, with no conventional risk factors presenting as VT. Coronary angiogram showed SCAD in right coronary artery without any flow limitation.

Spontaneous Coronary Artery Dissection (SCAD) is an unusual but important cause of acute coronary syndromes. We presented a case suffering from acute myocardial infarction with extensive SCAD confirmed on angiography. The use of intravascular ultrasound enabled identification of the extent of the disease and served as an important adjunct to successful percutaneous interventional treatment.

Spontaneous coronary artery dissection (SCAD) is a rare but devastating cause of the acute coronary syndrome, malignant arrhythmias, and sudden cardiac death. It mainly affects young, middle-aged and otherwise healthy women. Oral contraceptive pills (OCP) and connective tissue disease are known as predisposing factors for SCAD. Here, we present a 43-year-old woman with a history of systemic lupus erythematosus (SLE), using OCP came with typical chest pain. With diagnosing inferior ST-elevation myocardial infarction, fibrinolytic therapy was done which aggravated her chest pain. Finally, the diagnosis of SCAD was proven by angiography and stenting was done. On the 6th day of her hospitalization, tachycardia occurred again, and trans-esophageal echocardiography was performed for the patient who showed partially flail anterior mitral leaflet. She was discharged from hospital after mitral valve replacement. This is a great dilemma in the management of a young woman with a history of connective tissue disease or vasculitis, like our patient who wants a contraceptive method.
