- Body image is a concept, referring to feelings and attitudes toward: the body. There are many di fervent factors affecting the body image; historical, cultural, social and individual factors. The aim ofthis study was to describe young Indian women's body image. One hundred female university students in India answered the Ben-Tovim Walker Body attitudes questionnaire (BAQ). The result showed that Indian women had a sound body image.

- The ecotoxicological effect of after-usage released TiO2 nanoparticles in aquatic resources has been a major concern owing to their production and utilization in different applications. Addressing the issue, this study investigates the detailed in vivo molecular toxicity of TiO2 nanoparticles with Paramecium caudatum. TiO2 nano particles were synthesized at a lab scale using high energy ball milling technique; characterized for their physicochemical properties and investigated for their ecotoxicological impact on oxidative stress, steatosis, and apoptosis of cells through different biochemical analysis, flow cytometry, and fluorescent microscopy. TiO2 nanoparticles; TiO2 (N15); of size 36 +/- 12 nm were synthesized with a zeta potential of 20.2 +/- 8.8 mV and bandgap of 4.6 +/- 0.3 eV and exhibited a blue shift in UV-spectrum. Compared to the Bulk TiO2, the TiO2 (N15) exhibited higher cytotoxicity with a 24 h LC50 of 202.4 mu g/ml with P. Caudatum. The mechanism was elucidated as the size and charge-dependent internalization of nanoparticles leading to abnormal physiological metabolism in oxidative stress, steatosis, and apoptosis because of their influential effect on the activity of metabolic proteins like SOD, GSH, MDA, and catalase. The study emphasized the controlled usage TiO2 nanoparticles in daily activity with a concern for ecological and biomedical aspects.

- Extensive use of magnetic iron oxide (magnetite) nanoparticles (IONP) has raised concerns about their biocompatibility. It has also stimulated the search for its green synthesis with greater biocompatibility. Addressing the issue, this study investigates the molecular nanotoxicity of IONP with embryonic and adult zebrafish, and reveal novel green fabrication of iron oxide nanoparticles (P-IONP) using medicinal plant extract of Phyllanthus niruri. The synthesized P-IONP was having a size of 42 +/- 08 nm and a zeta potential of -38 +/- 06 mV with hydrodynamic diameter of 109 +/- 09 nm and 90emu/g magnetic saturation value. High antibacterial efficacy of P-IONP was found against E.coli. Comparative in vivo biocompatibility assessment with zebrafish confirmed higher biocompatibility of P-IONP compared to commercial C-IONP in the relevance of mortality rate, hatching rate, heart rate, and morphological abnormalities. LC50 of P-IONP and C-IONP was 202 mg/ml and 126 mg/ml, respectively. Molecular nanobiocompatibility analysis revealed the phenomenon as an effect of induced apoptosis lead by dysregulation of induced oxidative stress due to structural and functional influence of IONP to Sod1 and Tp53 proteins through intrinsic atomic interaction.
