Abstract
There is a pressing need to develop more effective therapeutics to fight cancer. An idyllic chemotherapeutic is expected to overcome drug resistance of tumors and minimize harmful side effects to healthy tissues. Antibody-functionalized porous silicon nanoparticles loaded with a combination of chemotherapy drug and gold nanoclusters (AuNCs) are developed. These nanocarriers are observed to selectively deliver both payloads, the chemotherapy drug and AuNCs, to human B cells. The accumulation of AuNCs to target cells and subsequent exposure to an external electromagnetic field in the microwave region render them more susceptible to the codelivered drug. This approach represents a targeted two-stage delivery nanocarrier that benefits from a dual therapeutic action that results in enhanced cytotoxicity.

Abstract
Aim: 20 years after establishment of the National Breastfeeding Committee, the present work, based on published data on breastfeeding, is aimed at providing insight into the development of breastfeeding behaviour in Germany. Methods: To identify relevant publications, a comprehensive literature search was conducted in PubMed and Web of Science using the search terms "breast feeding" or "breastfeeding" in combination with "Germany". The publication period was limited to the period 1995-2014. Results: A total of 35 studies with data on breastfeeding for the birth cohorts of 1990-2012 were identified. Most of the data had been collected in regional or local surveys, often retrospectively. About 60% of the studies had been conducted with the primary aim of collecting data on breastfeeding or infant nutrition. Over the past 2 decades, breastfeeding rates were always relatively high at the beginning (72-97%). However, they declined significantly within the first 2 months, and by the age of 6 months, only about 50% of infants were still breastfed. Conclusion: Breastfeeding support and early assistance should be offered to a greater extent in order to achieve sustainable improvement of breastfeeding frequency and duration in Germany. Regarding the quality of data collected on breastfeeding, it seems crucial to implement standardised approaches to monitor breastfeeding in Germany.
