Background: Nanotechnology is the future of orthodontic research. It has paved its way on advanced diagnostics, targeted drug delivery, biomaterials science and biosensors. Aim: The aim of the study is to evaluate the awareness of nanotechnology amongst dental students. Materials And Methods: A questionnaire containing 14 multiple choice questions were virtually given to postgraduate students and interns on the awareness of nanotechnology in orthodontics through WhatsApp. A total of 500 responses were recorded in a period of 3 weeks. Results: An average of 54% of dental questions had an awareness of usage of nanotechnology in orthodontics. Conclusion: Emphasis should be laid in the dental curriculum to advocate the usage of nanotechnology in dental practice, since nanoparticles is the future of dentistry.

This case report describes a 27-year-old man with a suspected intracranial foreign body due to a gunshot wound. Despite initial interpretation of a lodged bullet pellet on CT scan, further review by a Consultant Radiologist was requested due to medicolegal implications. The patient's condition deteriorated, leading to his death. This report highlights the importance of accurate imaging interpretation in cases of intracranial foreign bodies, especially in medicolegal contexts.

Recent advances in neuroimaging contribute to new insights regarding brain-behavior relationships and expand understanding of the functional neuroanatomical of language. Modern concepts of the functional neuroanatomical of language invoke rich and complex models of language comprehension and expression, such as dual stream networks. Increasingly, aphasia is seen as a disruption of cognitive processes underlying language. Rehabilitation of aphasia incorporates evidence based and person-centered approaches. Novel techniques, such as methods of delivering cortical brain stimulation to modulate cortical excitability, such as repetitive trans cranial magnetic stimulation and trans cranial direct current stimulation, are just beginning to be explored. In this review, we discuss the historical context of the foundations of neuroscientific approaches to language. We sample the emergent theoretical models of the neural substrates of language and cognitive processes underlying aphasia that contribute to more refined and nuanced concepts of language. Current concepts of aphasia rehabilitation are reviewed, including the promising role of cortical stimulation as an adjunct to behavioral therapy and changes in therapeutic approaches based on principles of neuroplasticity and evidence-based/person-centered practice to optimize functional outcomes. Objective: To determine the frequency of aphasia and its symptoms in stroke patients. Material and methods: A cross sectional survey was conducted through questionnaire from OPD of Govt. Medical College, Amritsar during 2018 to 2019. A sample of 162 Stroke patients was included in the study. The demographic details of the patients are male and female gender, age range between 25-70 years. A questionnaire was filled out based on history and clinical observation. All the collected data were entered into SPSS (statistical package for social sciences) for analysis. Results: The results indicated that 54.3% stroke patients have aphasia. Out of 162 patients 88 (54.3%) had aphasia and 74 (45.7%) had no aphasia. Among 88 patients of aphasia, 33 (37.5%) were male and 55 (62.5%) were females. Out of 88 aphasic patients 53.3% had Anomia, 33.30% had confronted repetition, 26.7% had Paraphasia and 23.3% had Agrammaticism and other associated problems were Disfluency, circumlocutions, reading and writing problems. Conclusion: The results of this study showed that the frequency of aphasia is 54.3% in stroke patients.

Type 2 diabetes mellitus (T2DM) is a serious public health problem accompanies with several complications. This study was conducted to evaluate the effects of chromium picolinate (CrPic) supplementation on the glycemic status and lipid profile in patients with T2DM. The patients with T2DM (n = 52) were randomly allocated into 2 groups. One group received 400 µg CrPic per day and the other group took placebo; the intervention duration was 8 weeks. Anthropometric indices and metabolic factors were measured at the beginning, and at end of the study. The patients were recommended not to change their normal diet, life style and medication. No significant changes were observed for weight, body mass index, and fasting blood glucose (FBG) in both groups; while intra-groups changes in homeostatic model assessment for insulin resistance (HOMA-IR) value was significant (p < 0.05). Results of analysis of covariance showed that there were significance differences between groups in total cholesterol, low density lipoprotein cholesterol and HOMA-IR at the end of the intervention adjusting for baseline levels (p = 0.035, 0.030 and < 0.001, respectively). In this study, oral supplementation with 400 µg CrPic for eight weeks did not alter FBG concentration as well as anthropometric parameters in individuals with T2DM. However, the modest beneficial effects of chromium supplementation on insulin resistance as indicated by HOMA-IR and lipid profile were found.

COVID-19, caused by a Sars-Cov-2, has led to a pandemic that threatens everyone everywhere all around the world. While healthcare and government leaders around the globe are focused on “flatten the curve” to slow down the spread of COVID-19, an emerging concurrent cry to “raise the line” of healthcare system capacity is also being showcased everywhere around the world. By flattening the curve, the peak of hospitalizations is lessened, softening the burden on hospitals with a lower surge in patients, but in order for the fight against the outbreak of COVID-19 to be fully effective, we must also ‘raise the line’ by increasing the capacity of healthcare system. A combination of ‘flattening the curve’ and ‘raising the line’ will save thousands of lives in the coming months and allow for a swifter end to the outbreak and a return to normal life.
