The objective of this paper is to trace the derivation of power through imperious surveillance upon the citizens of Panem and the consequent denial of citizen rights. The paper also analyses the nature of people’s fear of being watched and how the overbearing surveillance system in action can violate individual privacy. The act of being continuously watched or monitored and the knowledge of being under the control of power, a 'watchful eye', can create a huge impact upon the people under surveillance. In the modern world, people are being watched continuously and closely and are tracked through economic activities and electronic media. The paper aims to prove that surveillance in any form is a constraining force limiting people from being themselves. The Hunger Games by Suzanne Collins portray a dystopian post-apocalyptic land of Panem where the Capitol uses surveillance and the people’s fear of being watched as tools to assert their power over the citizens. After years of being watched and controlled, the people of Panem have forgotten basic citizen birthrights and the beauty of freedom in their lives. These people lose their real identity in this cage where they are devoid of any individual preferences. If the citizens are not completely aware of the value of privacy which is an inherent human right and much required for individual growth and development, the possibilities of losing the contemporary world to such a dystopian reality are high.

Nanotechnology is the art and science of material engineering in a scale of less than 100 nm. It is emerging as an interdisciplinary field that is undergoing rapid development and has brought about enormous changes in dental and medical fields. The field of nanotechnology has bright prospects as this evolutionary domain of science offers the possibility of great advances in the field of dentistry with an extrapolation of current resources to a new scale. A day may soon come when nano-dentistry will succeed in maintaining impeccable oral health through the aid of nanorobotics, nanomaterials and biotechnology. The new era of dentistry will encompass precisely regulated analgesia, tooth re-naturalization, complete cure for hypersensitivity and rapid orthodontic treatment. Dental nanorobotics is the most awaited and challenging application in nano-dentistry. This article gives an insight about the current status and the potential clinical applications of nano-technology,nano-medicine and nano-dentistry.

Sleep bruxism is a common phenomenon caused due to masticatory muscle activity during sleep .Proper methods for screening and diagnosing patients with Sleep Bruxism are crucial for the success of dental treatment. Literature reviews and clinical experiences indicate a lack of patient awareness and underreporting of sleep bruxism. Clinicians should look for clinical signs and symptoms of Sleep bruxism in the patient and deliver minimally invasive treatment modalities.

Background: India has been amongst the most affected nations during the SARS CoV2 pandemic, with sparse data on country wide spread of asymptomatic infections and antibody persistence. This longitudinal cohort study was aimed to evaluate SARS CoV2 seropositivity rate as a marker of infection and evaluate temporal persistence of antibodies with neutralization capability and to infer possible risk factors for infection. Methods: Council of Scientific and Industrial Research, India (CSIR) with its more than 40 laboratories and centers in urban and semi urban settings spread across the country piloted the pan country surveillance. 10427 adult individuals working in CSIR laboratories and their family members based on voluntary participation were assessed for antibody presence and stability was analyzed over 6 months utilizing qualitative Elecysys SARS CoV2 specific antibody kit and GENScript cPass SARS CoV2 Neutralization Antibody Detection Kit. Along with demographic information, possible risk factors were evaluated through self to be filled online forms with data acquired on blood group type, occupation type, addiction and habits including smoking and alcohol, diet preferences, medical history and transport type utilized. Symptom history and information on possible contact and compliance with COVID 19 universal precautions was also obtained. Findings:1058 individuals (10.14%) had antibodies against SARS CoV2. A follow up on 346 seropositive individuals after three months revealed stable to higher antibody levels against SARS CoV2 but declining plasma activity for neutralizing SARS CoV2 receptor binding domain and ACE2 interaction. A repeat sampling of 35 individuals, at six months, revealed declining antibody levels while the neutralizing activity remained stable compared to three months. Majority of seropositive individuals (75%) did not recall even one of nine symptoms since March 2020. Fever was the most common symptom with one fourth reporting loss of taste or smell. Significantly associated risks for seropositivity (Odds Ratio, 95% CI, p value) were observed with usage of public transport (1.79, 1.43 to 2∙24, 2.81561x10-6), occupational responsibilities such as security, housekeeping personnel etc. (2.23, 1.92 to 2.59, 6.43969x10-26), non smokers (1.52, 1.16 to 1.99, 0.02) and non vegetarianism (1.67, 1.41 to 1.99, 3.03821x10-8). An iterative regression analysis was confirmatory and led to only modest changes to estimates. Predilections for seropositivity was noted with specific ABO blood groups; O was associated with a lower risk. Interpretation: In a first of its kind study from India, we report the seropositivity in a country wide cohort and identify variable susceptible associations for contacting infection. Serology and Neutralizing Antibody response provides much sought for general insights on the immune response to the virus among Indians and will be an important resource for designing vaccination strategies.

Herein we report a ratiometric naturally occurring fluorescent pH probe, berberrubine (BBn) for the direct detection of diabetic ketoacidosis (DKA) conditions of patients having type I diabetes mellitus. The photophysical properties of the probe during pH titrations showed remarkable changes in absorption spectra where two absorption bands at 377 and 326 nm have disappeared followed by the emergence of an absorption maxima at 346 nm in highly acidic conditions. In addition, a fluorescence enhancement effect was observed in the alkaline pH, with a bathochromic shift of 33 nm. Moreover, the solution switches the color from light yellow to light pink with the change of pH from acidic to basic. A pKa value of 7.57 and a good linearity between pH 5.0–9.0 indicate that the probe can be used efficiently for the DKA condition, where pH variations are in the range of 6–7. The excellent water solubility, photostability, reversibility, and selectivity of BBn make it a potential pH sensing agent for acidic microenvironments. The reversible sensing of pH variations during DKA could be effective in primary detection and diagnosis which can assist in avoiding further complications of acidosis.
