Cardiac angiosarcoma is the most common among primary malignant cardiac tumors in adults. Malignant cardiac tumors commonly arise in the right-sided cardiac chambers unlike benign tumors that commonly arise in the left-sided chambers. Cardiac tumors on the left side need to be carefully assessed for malignant features for deciding treatment strategy and prognostication. We present the case of a 62-year-old female with a large left atrial mass infiltrating the interatrial septum and adjacent myocardial wall. Histology was suggestive of angiosarcoma. Although a radical excision was done, the tumor recurred within 6 months of the postoperative period and she died shortly after the recurrence.

The current era of industrialization includes a constantly increasing demand for plastic products, but because plastics are rarely recycled and are not biodegradable plastic pollution or “white pollution” has been the result. The consumption of petroleum-based plastics will be 20% of global annual oil by 2050, and thus there is an inevitable need to find an innovative solution to reduce plastic pollution. The biodegradable and environmentally benign bioplastics are suitable alternative to fossil-based plastics in the market due to sustainability, less carbon footprint, lower toxicity and high degradability rate. Microalgal species is an innovative approach to be explored and improved for bioplastic production. Microalgae are generally present in abundant quantity in our ecosystem, and polysaccharide in the algae can be processed and utilized to make biopolymers. Also, these species have a high growth rate and can be easily cultivated in wastewater streams. The review aims to determine the recent status of bioplastic production techniques from microalgal species and also reveal optimization opportunities involved in the process. Several strategies for bioplastic production from algal biomass are being discussed nowadays, and the most prominent are “with blending” (blending of algal biomass with bioplastics and starch) and “without blending” (microalgae as a feedstock for polyhydroxyalkanoates production). The advanced research on modern bioengineering techniques and well-established genetic tools like CRISPR–Cas9 should be encouraged to develop recombinant microalgae strains with elevated levels of PHA/PHB inside the cell.

Choice of initial revascularization strategy is unclear in Covid-19 patients with acute ST-elevation myocardial infarction (STEMI). We present clinical, angiographic profile, and response to therapy in 09 covid-19 STEMI patients. STEMI was the initial presentation in 6 and developed in first-week of covid symptoms in 3 patients. D-dimer and C-reactive protein was raised in all. Right coronary artery was the most common culprit artery. Five patients underwent primary-PCI. Three out of 4 patients who underwent thrombolysis, required rescue-PCI. All 9 patients had high thrombus burden with total or near-total occlusion of culprit artery and 3 of them required thrombosuction.
