Use of Three Pre-Injection Procedures to Reduce Pain Perception of Intraoral Injections in Eight- to 12-Year-Old Children: Randomized Controlled Trial.

To compare the efficacy of laser phototherapy, Buzzy®, and lignocaine gel in minimizing pain during intraoral injections. In this randomized controlled trial, the efficacy of standard lignocaine gel (Group A) was compared with Buzzy® (Group B) and laser phototherapy (Group C) as pre-anesthetic agents in 15 children aged eight to 12 years undergoing intraoral local anesthesia (LA). Pain perception during needle insertion was assessed objectively using the Face, Legs, Activity, Cry, Consolability (FLACC) scale and subjectively using the Visual Analogue Scale (VAS).

Need for operational simplicity and timely disbursal of benefits-a qualitative exploration of the implementation of a direct benefit transfer scheme for persons with tuberculosis in India.

Background: Ni-kshay Poshan Yojana (NPY) is a direct benefit transfer scheme of the Government of India introduced in 2018 to support the additional nutritional requirements of persons with TB (PwTB). Our recent nationwide evaluation of implementation and utilization of NPY using programmatic data of PwTB from nine randomly selected Indian states, reported a 70% coverage and high median delay in benefit credit. We undertook a qualitative study between January and July 2023, to understand the detailed implementation process of NPY and explore the enablers and barriers to effective implementation and utilization of the NPY scheme.

Correction: A photocatalytic chip inspired from the photovoltaics of polymer-immobilized surfaces: self-assembly and other factors.

Correction for 'A photocatalytic chip inspired from the photovoltaics of polymer-immobilized surfaces: self-assembly and other factors' by Periyamuthu Ramar , , 2021, , 12964-12967, https://doi.org/10.1039/D1CC04381A.

A photocatalytic chip inspired from the photovoltaics of polymer-immobilized surfaces: self-assembly and other factors.

Polymers and carbon nanomaterials for bulk heterojunction photovoltaic devices have been used to develop an efficient reusable photocatalytic chip. Interestingly, it is highly effective when the materials are self-assembled in a particular pattern at a particular concentration ratio (Movies in the ESI).

Iron Mineralizing Bacterioferritin A from Mycobacterium tuberculosis Exhibits Unique Catalase-Dps-like Dual Activities.

Mycobacterium tuberculosis ( Mtb) expresses heme binding protein nanocages, bacterioferritin A (BfrA), along with nonheme bacterioferritin B (BfrB). BfrA is unique to bacteria and, like BfrB, carries out ferroxidase activity to synthesize iron oxide biominerals. The expression of BfrA, in the presence of BfrB, indicates that Mtb may utilize it for some additional purpose apart from its natural iron storage activity.

Dental Caries Experience, Dental Anomalies, and Morphometric Analysis of Canine among Monozygotic and Dizygotic Twins.

Background: The study of twins is a well-known and a unique method that is used to investigate the genetic contributions to physical features and diseases in human.

Aim: To estimate the relative contributions of genetic and environmental influence to observed variations in different dental features or traits.

Methodology: Thirty twins in the age group of 15-30 years were selected for the study, and the dental caries experience scores, dental anomalies, and morphometric analysis of monozygotic (MZ) and dizygotic (DZ) twins were compared.
