One of the most important steps to improve the quality of life of street-connected children is to gain experiences and assess their needs, with the children themselves being the best source for this information. Therefore, this research aims to identify the experiences and needs of street children using their own insights. The research methodology employed in this study was qualitative, utilizing thematic analysis and semi-in-depth interviews. Maximum variation purposive sampling was employed to capture a range of experiences among street-connected children. Following data collection and analysis, four main themes emerged: 'The street as an entry into a new world', 'The street as a place for experience and love', 'The street as a place for survival', and 'The street as a place for pain and suffering'. This study uncovers the complex realities of street-connected children, revealing the factors driving them onto the streets and challenging misconceptions. Despite facing profound challenges, these children demonstrate resilience and aspirations for a better future. The study underscores the importance of supportive environments, education, healthcare, and inclusive policymaking to address the systemic factors perpetuating their vulnerability.

Sexual contact is still one of the most important routes of HIV transmission. The aim of this study was identify the factors that underlie the higher prevalence of high-risk sexual behaviors in a sample of transgender women in Iran. The qualitative study used face-to-face, semi-structured, in-depth interviews in a sample of 15 transgender women. Our participants used sexual practices as a way to be approved/accepted as a woman. Using sex for this purpose led them to engage in high-risk sexual relationships. It is essential to consider these issues in consulting and education about high-risk behaviors.

Multi-walled carbon nanotubes (MWCNT) were used to separate amoxicillin from aqueous media. The parameters affecting amoxicillin adsorption such as pH, temperature, time, interferences of similar molecules, and the amount of adsorbent used were studied. Amoxicillin adsorption using MWCNT was compared to that using Fullerene C60 and activated carbon (AC). The adsorption efficiency of 0.1 and 0.2 g of MWCNT using in a continuous mode were 86.5% and 87.9%, respectively. Evaluation of the adsorbent capacity showed that each gram of MWCNT can absorb 22.9 mg amoxicillin. The effect of pH was studied over the range 2–8 and revealed that adsorption of the amoxicillin at the initial pH of 4.6 was more effective than any other pH. The adsorption of amoxicillin on MWCNT was much greater than Fullerene C60 and AC. Adsorption data showed that they were best fitted to the Langmuir isotherm. [ABSTRACT FROM PUBLISHER]
