A Highly Selective Pyrene Appended Oxacalixarene Receptor for MNA and 4-NP Detection: an Experimental and Computational Study.

A novel pyrene-substituted oxacalixarene was designed and synthesized as a selective probe for the simultaneous detection of MNA and 4-NP. Utilizing 1H-NMR, 13C-NMR, and FT-IR analysis techniques, its structure was characterized. The binding property of BPOC to a variety of NACs, including 1,3-DNB, 2,3-DNT, 2,4-DNT, 2,6-DNT, 4-NP, 4-NT, and PA, revealed that the sensor binds to MNA and 4-NP with remarkable selectivity.

Assessment of Prosocial Behaviour of School-Going Adolescents: A Cross-Sectional Survey.

Introduction: Prosocial behaviour is one of the key features of the development of school-going adolescents. Therefore, the current paper focuses on the prosocial behaviour of school-going adolescents in Kollam District, Kerala.

Methodology: A cross-sectional descriptive study where 600 school-going adolescents, their parents and 60 class teachers were selected through cluster sampling method.

Prevalence of Emotional and Behavioral Problems among School-Going Adolescents: A Cross-Sectional Study.

Background: Adolescence is a period of several emotional, mental, and behavioral changes, and many adolescent problems are manifested in the form of emotional problems, conduct problems, hyperactivity, and peer-related problems. The objectives of the current study are to assess the prevalence of emotional and behavioral problems across gender and location. It analyzes the Strengths and Difficulties Questionnaire (SDQ) total score with sociodemographic details among school-going adolescents in Kollam district.

Assessment of mental health status among school going adolescents in North East India: A cross sectional school based survey.

Background: Adolescent emotional responses and behaviors are often passed off as growth pangs and academic stress, thereby missing those that need deeper understanding and mental health interventions.

Aim: The aim of the study is to understand mental health status among the school adolescents in Tezpur, Assam.

Materials And Methods: The present study was a cross sectional study that used convenience sampling in selection of the schools.

Novel cationic quinazolin-4(3H)-one conjugated fullerene nanoparticles as antimycobacterial and antimicrobial agents.

A series of novel cationic fullerene derivatives bearing a substituted-quinazolin-4(3H)-one moiety as a side arm were synthesized using the 1,3-dipolar cycloaddition reaction of C60 with azomethine ylides generated from the corresponding Schiff bases of substituted quinazolinones. The synthesized compounds 5a-f were characterized by elemental analysis, FT-IR, 1H NMR, 13C NMR, and ESI-MS and screened for their antibacterial activity against Mycobacterium tuberculosis (H37RV) and antimicrobial activity against selected Gram-positive (Staphylococcus aureus and S. pyogenes) and Gram-negative (Pseudomonas aeruginosa, Klebsiella pneumonia and Escherichia coli) bacterial and fungal strains (Candida albicans, Aspergillus clavatus, and A.
