Ancient DNA (aDNA) is used to explore the genetic landscape of the past and investigate the movement, mixture, and adaptation events that shaped present-day patterns of human genetic diversity. The present study was designed to explore the genetic composition of the ancient people of Sri Lanka. Despite the low amino acid racemization often found in

Oral squamous cell carcinoma (OSCC) is the second most common cancer in Sri Lanka. Tumor growth and metastasis depend on angiogenesis and lymph angiogenesis triggered by chemical signals from tumor cells in a phase of rapid growth. Different factors are known to induce the angiogenesis process. The most important angiogenic factor is Vascular endothelial growth factor (VEGF).

specialists to medical students. Since the expected number of calls was high, the service decided to recruit and train medical students as first contact responders. At the time of initiation, medical education of students in Sri Lanka was limited to online lectures and clinical training was on halt for most academic batches. Thus, recruiting medical students to the system created the opportunity to train them in healthcare provision without actually exposing them to the ongoing pandemic.Volunteers were invited through social media groups. The volunteers, including doctors and medical students, were trained separately via initial online training programmes. Training needs were identified according to the diverse levels of knowledge and experience of volunteers. A range of competencies, including clinical reasoning, patient management, communication skills, teamwork, health education and handling difficult situations had to be inculcated. This included training on how to assess a patient and get all essential information within the system allocated time limit of 10 minutes.
