Socio-Economic Dimensions of Adoption of Conservation Practices: What Is Needed to Be Done?

Promoting sustainable agricultural production requires farmers to adopt new technologies such as organic farming to increase the agricultural productivity, while conserving the environment. Adoption and diffusion of new technologies need a long process, as experienced in the past. There are social and economic factors, identified in the literature, and those could cause delays in farmers’ use of new technologies. Hence, technology adoption and diffusion are important policy issues in agriculture. For that reason, this paper provides a literature review including factors influencing the adoption and diffusion of technology in agriculture and aims to contribute to the future studies and policies, especially focusing on the social capital or the social aspects, which are proven not to be analyzed by the previous studies comprehensively. The results show that interaction with neighbors and relatives, and membership in a group or organization, which represent the social aspects, has a positive influence on adoption and diffusion of new technologies. Hence, policy-makers should incorporate the social aspects when designing the policies, such as cost sharing programmes, to promote adoption and diffusion of new technologies

Cytotoxicity and apoptotic effects of nickel oxide nanoparticles in cultured HeLa cells.

The aim of this study was to observe the cytotoxicity and apoptotic effects of nickel oxide nanoparticles on human cervix epithelioid carcinoma cell line (HeLa). Nickel oxide precursors were synthesized by an nickel sulphate-excess urea reaction in boiling aqueous solution. The synthesized NiO nanoparticles

Usefulness of CA 15-3 for breast or ovarian primary sites in metastatic adenocarcinoma of pleural fluid

Kilic, Murat/0000-0002-1377-2021WOS: 000302197000005This study was conducted to evaluate the diagnostic value of CA 15-3, mammaglobin, c-erbB-2, estrogen receptor (ER), progesterone receptor (PR), CK 20, and CA 125 for detecting metastatic breast and ovarian carcinoma in pleural fluids. The material under study consisted of 26 pleural effusions from invasive breast and ovarian cancer patients from the Hannover Cytopathology Institute. Expressions of these markers were studied using immunocytochemistry. All of the breast cancer cases studied showed a positive reaction with CA 15-3, while only 36% with mammaglobin, 21% with c-erbB-2, 36% with ER, and 7% with PR were positive. The sensitivities of CK 20, CA 15-3, and CA 125 as markers for metastatic ovarian carcinoma were 43%, 88%, and 55%, respectively. Our results indicate that CA 15-3 has a higher sensitivity than other tumor markers for diagnosing metastatic breast and ovarian carcinoma in pleural fluids

Cytotoxicity and apoptotic effects of nickel oxide nanoparticles in cultured HeLa cells

The aim of this study was to observe the cytotoxicity and apoptotic effects of nickel oxide nanoparticles on humancervix epithelioid carcinoma cell line (HeLa). Nickel oxide precursors were synthesized by an nickel sulphate-excess ureareaction in boiling aqueous solution. The synthesized NiO nanoparticles (<200 nm) were investigated by X-ray diffractionanalysis and transmission electron microscopy techniques. For cytotoxicity experiments, HeLa cells were incubated in50-500 μg/mL NiO for 2, 6, 12 and 16 hours. The viable cells were counted with a haemacytometer using light microscopy.The cytotoxicity was observed low in 50-200 μg/mL concentration for 16 h, but high in 400-500 μg/mL concentration for2-6 h. HeLa cells' cytoplasm membrane was lysed and detached from the well surface in 400 μg/mL concentration NiOnanoparticles. Double staining and M30 immunostaining were performed to quantify the number of apoptotic cells in cultureon the basis of apoptotic cell nuclei scores. The apoptotic effect was observed 20% for 16 h incubation
