Recently nanotechnology has become an integral part of modern biomedical applications. Accordingly, nanoparticles are considered as promising components for the development of innovative tags, probes, biosensors and carrier molecules for drug delivery. Spherical colloidal gold nanoparticles (AuNPs) are prime candidates to be utilized for these purposes due to their useful physical properties. However, in order for the gold nanoparticles to be used in nanomedicine, their biological properties should be extensively studied as well. Therefore, in this paper we chemically synthesized gold nanoparticles and studied their physical and biological characteristics to determine their potential use in medicine. Gold nanoparticles were synthesized by the reduction of chloroauric acid (HAuCl4) solution with sodium citrate. The physical properties of the AuNPs were determined by UV–vis spectrophotometer and Zetasizer readings. The antimicrobial activity of the newly synthesized gold nanoparticles on Escherichia coli, Salmonella infantis, Salmonella kentucky, Salmonella typhimurium, Salmonella enteritidis, Pseudomonas aeruginosa, Listeria monocytogenes, Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Bacillus subtilis and Candida albicans were investigated via disk diffusion method. We found that the AuNPs were monodisperse, stable and not prone to aggregation with an average size of 22.12 nm and an emission band at 522 nm. The disk diffusion tests revealed that the gold nanoparticles did not have a significant growth inhibitory effect on the pathogens tested. In conclusion, here we showed the successful synthesis of gold nanoparticles by a safe and non-toxic method. Furthermore, our evaluation of the antimicrobial activity of these nanoparticles suggests that these molecules could be considered as biologically safe molecules for future medical applications.

Su ürünleri yetiştiriciliğinde balık refahı ve çalışma kolaylığı açısından sentetik veya bitkisel kökenli anestezikler kullanılmaktadır. Ancak, sentetik kökenli anesteziklerin balık vücudunda birikim yapması nedeni ile hem balık hem de tüketici sağlığını tehdit edebilmektedir. Dolayısıyla son yıllarda bitkisel kökenli anesteziklere olan ilgi giderek artmaktadır. Karanfil yağı su ürünleri yetiştiriciliğinde yapılan çalışmalarda sıklıkla kullanılan bitkisel bir anestezik maddedir. Literatürde karanfil haricinde farklı bitkisel kökenli esansiyel yağların balıklar üzerindeki anestezik etkilerinin araştırıldığı çalışmalar bulunmaktadır. Bu yağlardan birisi de kişniş otu (Coriandrum sativum) yağıdır. Kişniş otu ana bileşen olarak %50-70 oranlarında anestezi özelliği gösteren linalol etken maddesini içermektedir. Bu çalışmada, bitkisel anestezik olarak kişniş otu yağının su ürünlerinde kullanılabilirliği değerlendirilmiştir.

Ginger (Zingiber officinale) is one of the important spices in the world. Nepal is the fourth largest producers of ginger in the world, which produced 271.863 MT in 2016. In Nepal, seventy districts are producing ginger and around 400.000 households are involving in the ginger farming which is the chief source of the household income. Moreover, ginger has prioritized by several policies and strategies of the Government of Nepal. This paper examined the production trend and market access of Nepali ginger considering the ginger global market. A diagnostic study of production, value addition, and the marketing system was carried out between the eastern and the western part of Nepal. The secondary information was reviewed and analysed for the study. Likewise, the key informant survey was performed for the primary data and information. For Nepali ginger, India is found constantly top destination. The result of price index suggested that Nepali ginger is losing significant potential earning by not having top most lucrative markets for fresh ginger. Moreover, the trend of the export is ever fluctuating and the result showed that trade of ginger to India in term of export is more stable from the western region as compared to the eastern region. The study found that the major determinants of ginger market access are quality of ginger produced, value addition, level of trade facilitation, and domestic production and the import of India from other countries.
