Characterization and applications of iron oxide nanoparticles synthesized from Phyllanthus emblica fruit extract

Plos.org 

by Easha Fatima, Iqra Arooj, Hamna Shahid, Abida Aziz

Nanotechnology is a treasure trove of diversified themes which are endowed with broad applications. Herein, iron oxide (Fe2O3) nanoparticles were synthesized using Phyllanthus emblica aqueous fruit extract. The UV-Visible spectrum exhibited a surface plasmon resonance peak at 295nm. Fourier Transform Infrared Spectroscopy provided insight into the functional groups responsible for capping. X-ray diffraction analysis authenticated the crystalline nature of nanoparticles...

Buying inferior to selling: Explore the impact of transaction direction on the effects of related-party transactions

Plos.org 

by Shuang Li, Jie He

Throughout, the effects of related-party transactions (RPTs) have been a hot topic in financial markets and corporate governance research. This paper analyzes the theoretical foundation of the effects of RPTs and constructs a new indicator, the quasi-profit margin, to assess the effects of RPTs by studying their impact on the quasi-profit margin. Based on the information asymmetry between transaction parties and the information screening theory, the paper proposes the buying inferior to selling theory... Читать дальше...

Spatial patterns and associated factors of HIV testing and counselling (HTC) as a component of antenatal care services in Ethiopia

Plos.org 

by Tigabu Kidie Tesfie, Werkneh Melkie Tilahun

Background

While HIV testing and counselling play a crucial role in preventing mother-to-child transmission, numerous pregnant women did not receive these services. Understanding the spatial variation of HIV testing and counselling and its associated factors during antenatal care in Ethiopia remains limited. Thus, this study was aimed at assessing the spatial patterns and factors associated with HIV testing and counselling during antenatal care visits in Ethiopia. Читать дальше...

Identification of a highly efficient chloroplast-targeting peptide for plastid engineering

Plos.org 

by Chonprakun Thagun, Masaki Odahara, Yutaka Kodama, Keiji Numata

Plastids are pivotal target organelles for comprehensively enhancing photosynthetic and metabolic traits in plants via plastid engineering. Plastidial proteins predominantly originate in the nucleus and must traverse membrane-bound multiprotein translocons to access these organelles. This import process is meticulously regulated by chloroplast-targeting peptides (cTPs). Whereas many cTPs have been employed to guide recombinantly... Читать дальше...

Jalopnik.com 

The legendary West Coast delicacy that is In-N-Out Burger has an incredibly simplistic menu that has hardly changed throughout its 75-year history, and yet the In-N-Out behind my apartment building has a line wrapping around the block every single day. Sometimes you have to know when you get a recipe right; you don’t…
