This study does a bibliometric analysis based on keywords of conference proceedings. Scientometric investigations of conference
proceedings are a new and innovative, not very common approach. The studies and papers presented may be interpreted as early
indicators of scientific development. The Academy of International Business (AIB) was chosen for being the leading organization
for studies in international business with contributions covering a 3-year period (2006–2008). The study presents the general
structure of current scholarly interest in international business studies, clusters the keywords and reflects details on the
focused research areas of the papers analyzed. The bibliometric analysis indicates three clusters: the core, the semi-periphery
and the periphery. The five most occurring keywords were found to be multinational enterprise, emerging markets, foreign direct
investment, internationalization and knowledge management in descending order. The analyses focus on concepts building the
core (in total ten keywords), the semi-periphery which is coined by performance and related topics (60 keywords) and the periphery
of the studies with governance and specific facets of it (199 keywords).

Diethylstilbestrol (DES) is a well known, nonsteroidal estrogen with high affinity for the estrogen receptor (ER). Today DES
is used to treat breast and prostate cancers. A phosphate derivative of DES [Diethylstilbestrol diphosphate (DES-P)] which
is specific to tumor cells consisting alkaline phosphatase enzyme was synthesized and labeled with 99mTc using tin chloride as reducing agent. In vivo biological activity of 99mTc labeled diethylstilbestrol phosphate compound (99mTc-DES-P) was examined by biodistribution studies on Wistar Albino rats. Statistical evaluation was performed using SPSS 13
program. The percentage (%) radiolabeling yield of 99mTc-DES-P and quality control studies were done by Thin Layer Radio Chromatography (TLRC). Results showed that, 99mTc-DES-P may be proposed as an imaging agent for ER enriched tumors such as uterus and prostate and their metastases in bones.
