In this chapter information is provided about the outer layer of the skin, the epidermis, and the predominant cells comprising this epithelium, the keratinocytes. The evidence supporting a possible role for the lipid-metabolizing enzyme phospholipase D in regulating keratinocyte differentiation is also discussed. A detailed protocol for the preparation of primary cultures of epidermal keratinocytes from neonatal mice is described, to allow other investigators to obtain data concerning these important cells involved in forming and maintaining the mechanical and water permeability of the skin. Finally, a complete protocol for monitoring phospholipase D activity in intact cells is supplied in the hope that additional research will result in a better understanding of the role of phospholipase D in controlling keratinocyte proliferation and differentiation.

In this study, composite films were developed by encapsulating cassia oil (CO) with β-cyclodextrin through a microencapsulation technique and incorporating it into a chitosan (CS), polyvinyl alcohol (PVA) and glycerol matrix. The primary objective of the film was to inhibit bacterial growth on the surface of fresh bananas and extend their shelf life. Characterization methods were employed to evaluate the physical properties and functionality of the composite films.

However, diagnostic material for molecular testing is often represented by cytological samples which are generally scarce and span a wide range of preparation types. Thus, the primary objective is to efficiently manage materials for molecular profiling.

Because of the vertical transmission of avian leukosis virus subgroup J (ALV-J), control of ALV-J in breed of chicken is still a serious issue. Blocking vertical transmission using antibodies is a potential strategy, but its high cost limits its application. We artificially designed recombinant nanobody (Nb) and efficiently expressed and secreted them in three primary chicken cells cultured in vitro by adenovirus delivery.

Electronic address:
Electrocoagulation (EC) has proven its high efficiency and environmental sustainability for treating several types of wastewaters. However, the primary drawbacks of the conventional EC process are the suitable electrode materials and the relatively high cost due to the requirement for electric energy. To overcome these practical challenges, this study investigated effective oil/water separation by a solar-powered electrocoagulation (SPEC) process using a novel highly conductive basalt fabric (BF) cathode.
