Calcifying Odontogenic Cyst – A Three-Dimensional Radiological Evaluation By Cone Beam Computed Tomography, Karthik Rajaram Mohan, Saramma Mathew Fenn, Ramachandra Reddy Venkatesha

International Arab Journal of Dentistry

Calcifying odontogenic cysts is an odontogenic cyst that gives rise to painless swelling which expand and occasionally perforate bone. Most of them are between 2 to 4 cm in diameter. Approximately 75% occur in anterior canine-incisor region. The highest incidence of occurrence is between 10 and 29 years. Radiographically they appear as well-circumscribed, unilocular cystlike areas with scattered radiopacities which range from mere flecks to large masses. The related tooth usually gets displaced. Radiopaque flecks occur in radiographic features of some lesions which undergo osteolysis during their development. They occur as a result of dystrophic calcifications in long standing chronic …

Rehabilitation Of A Patient With Single Complete Tooth-Supported Overdenture Against The Unmodified Natural Dentition Using Functionally Generated Path Technique: A Case Report, Akanksha Shinde, Nilesh Bulbule, Varun Bhatt, Gayathri Balachandran, Amit Jagtap

International Arab Journal of Dentistry

Meyer’s proposed chew-in technique also called functionally generated path (FGP) technique, is indicated for the restoration of an edentulous arch that is opposed by natural teeth as it does seem to provide the most accurate method of recording occlusal patterns, also help to minimize the effects of negative factors, and to overcome the deficiencies of articulators. As stated by Rudd and Morrow, this technique is especially suitable for tooth-supported complete dentures, due to inherent stability of tooth-supported record bases helps in recording jaw relationships accurately. Whenever a single complete denture is opposed by natural dentition, problems observed are abrasion of …

Clean Vehicles Tax Credits Under The Us Inflation Reduction Act: Friend-Shoring Takes Centre Stage In Us Policy, J. Anthony Vanduzer

Indian Journal of International Economic Law

The international market has recently faced significant disruptions owing to major geo-political events such as the Covid-19 Pandemic and the Russia-Ukraine War, resulting in unreliable and erratic global supply chains. In a bid to create and secure more sustainable supply networks, countries have adopted ‘friend-shoring’ policies, encouraging their enterprises to source supplies from friendly or allied nations. While the primary objective of these policies is to stabilize global supply chains, these initiatives also stem from a desire to reduce reliance on countries that pose a threat to the geopolitical order.

Although tailored as a market-based strategy, these friend- shoring policies, …

Asymmetric Challenges In Cybersecurity Among Wto Members : A Justification For A Veiled Trade Barrier?, Daniel Oluwadayo Akindipe, Love Gbenga-Fabusiwa

Indian Journal of International Economic Law

There is a higher prevalence of cyberattacks amongst the least developed and the developing country members of the World Trade Organization (WTO) than its developed country members. To proffer appropriate safeguards against cyberthreats, developed country members are adopting solutions outside of the WTO with Preferential Trade Agreements that specifically make provision on cybersecurity. Normative doctrinal research methodology was used in this research to analyze applicable legislation and rules that are applicable to the WTO members in the area of cybersecurity. The study revealed that the WTO does not have adequate provisions regarding the cybersecurity challenges of its least developed and …

International Investment Agreements And Regulation Of Utilisation Of Water Resources In Africa, Dominic Npoanlari Dagbanja

Indian Journal of International Economic Law

African constitutions and domestic water legislation provide for the human right to clean and safe drinking water. This right is also sourced from international human rights treaties and declarations to which African states are parties or signatories. Both municipal law and public international law impose the duties of protection and fulfilment of the right to safe drinking water on states. Domestic water laws and regulations require African states to regulate and manage the utilisation of water resources including by approving the grant of rights, concessions, or contracts in respect of the exploitation of water resources. These laws also require the …

Turf Wars And Red Herrings: Recent American Legislations And Their Impact On Global Evs And Semiconductors Trade, Manya Gupta, Arnav Sharma

Indian Journal of International Economic Law

In 2022, the United States began a new journey dedicated to revitalizing its long-lost industrial potential through the Inflation Reduction and CHIPS Acts. While appearing to be classic industrial policies aimed at boosting manufacturing potential in concerned areas, the Acts also mark an attempt at shifting global supply chains to the advantage of the United States. The seemingly innocuous titles of these legislations point towards combating inflation and producing microchips. However, the Acts mask the US’ attempts at shifting critical supplies to domestic or allied territories and must be approached with caution. The Acts contain measures that may attract some …

Regulating Subsidies Contributing To Overcapacity And Overfishing: How India Proposes To Align Trade Policy With Sustainable Fisheries, Pallavi Arora, Ketakee Gondane, Mumrita Gaurdwaj

Indian Journal of International Economic Law

In light of the growing impetus to integrate sustainability issues into the World Trade Organisation (WTO), facilitating coordination between the trade and sustainability regimes has taken centre stage. Managing regime interaction was integral to negotiating the Agreement on Fisheries Subsidies (AFS), the WTO’s first sustainability agreement. As the outstanding element of the AFS, the overcapacity and overfishing (OCOF) pillar also aims to foster harmony between the principles and concepts of international environmental law, particularly fisheries law and international trade law. Notable in this regard are the principles of sustainable development and common but differentiated responsibilities and respective capabilities. Also relevant …

Gonnella, Aldo Giudice, Carmine Vecchione, Annibale Alessandro Puca, Mario Capunzo

Department of Medicine Faculty Papers

Longevity, as a complex life-history trait, shares an ontogenetic relationship with other quantitative traits, such as epigenetic and environmental factors. Therefore, it is important to identify environmental factors that may modify the epigenome to establish healthy aging. This study explored the association between tap drinking water and longevity in Cilento, Italy, to understand whether trace elements in local drinking water may have an influence on old, nonagenarian, and centenarian people and promote their health and longevity. Data on population and water sources were collected through the National Demographic Statistics, the Cilento Municipal Archives, and the Cilento Integrated Water Service. Ordinary …

Medication Initiation, Patient-Directed Discharges, And Hospital Readmissions Before And After Implementing Guidelines For Opioid Withdrawal Management, Jillian Zavodnick, Md, Nicolette M. Heinsinger, Angelo C. Lepore, Robert C. Sterling

Department of Medicine Faculty Papers

OBJECTIVES: Rising rates of hospitalization for patients with opioid use disorder (OUD) result in high rates of patient-directed discharge (PDD, also called "discharge against medical advice") and 30-day readmissions. Interdisciplinary addiction consult services are an emerging criterion standard to improve care for these patients, but these services are resource- and expertise-intensive. A set of withdrawal guidelines was developed to guide generalists in caring for patients with opioid withdrawal at a hospital without an addiction consult service.

METHODS: Retrospective chart review was performed to determine PDD, 30-day readmission, and psychiatry consult rates for hospitalized patients with OUD during periods before (July …
