AbstractMusa sp. cultivar Rasthali (Silk AAB) is a choice variety of the Asian sub-continent. Its production and sustenance are threatened by Fusarium wilt, which affects the livelihoods of small and marginal farmers. The use of quality planting material is one of the strategies to manage the disease. Availability of quality planting material for varieties other than Grand Naine is limited. Large-scale micropropagation using existing technologies is laborious and expensive. Temporary immersion bioreactor system is emerging as a potential advancement in the micropropagation industry. In this study, a cost-effective temporary immersion bioreactor (TIB) system has been developed and an efficient micropropagation method has been standardized. Explants cultured in TIB with 250 ml of culture medium in a 2-min immersion frequency of 6 h were found to be efficient for shoot proliferation and rooting. Its efficacy has been compared with the semisolid culture method. At the end of the 6th subculture, 1496 ± 110 shoots per explant were obtained in TIB. Chlorophyll, carotenoid, stomatal index, and the number of closed stomata were examined to determine the physiological functions of the plants grown in TIB and compared with semisolid grown plantlets. Plantlets grown in TIB were genetically stable and were confirmed using inter-simple sequence repeat (ISSR) markers. The multiplication of shoots in TIB was 2.7-fold higher than the semisolid culture method, which is suitable for large-scale production of planting material for commercial applications.

Banana is an important crop in the tropics which possess the potential for commercial production in Nigeria. Large scale production requires large volume of planting materials which may be difficult to obtain using conventional methods of propagation. Temporary immersion bioreactor system (TIBs) is a cost effective method for micropropagation of plants. The present study was carried out to develop an efficient method for rapid multiplication of banana using temporary immersion bioreactor system (TIBs). Banana microshoots were regenerated from young suckers obtained from field grown plants using conventional plant tissue culture. Microshoots of 2cm length were used as explants for multiplication in temporary immersion bioreactor system. Ten (10) explants were cultured in bioreactor bottles containing Murashinge and Skoog (MS) liquid media supplemented with different concentrations of 6-bezylaminopurine (BAP) with or without 250mg/L Activated Charcoal (AC). Results showed that explants cultured in media supplemented with 2 mg/L or 1mg/L BAP without AC gave the highest shoot multiplication rate of 900% and 800%, respectively compared to hormone free media. Production of competent plants (plants ready for ex vitro establisment) were however, influenced by the presence of AC and the highest percentage of competent plants (80%) were produced when media was fortified with 1mg/L BAP+ 250mg AC. Regenerated plants were successfully established in the field and were morphologically normal and fertile.

Mango ginger (Curcuma mangga Valeton & Zijp.) is an underutilized rhizomatous species that has been valued in tropical Asian countries as a source of vegetable, spice, salad, medicine, and essential oil. This species is hardy and requires less care for obtaining good yields. Rhizomes are the commonly used propagules for the species, which are also the economic part of the crop. Huge quantity of seed rhizomes is required to promote this crop in larger areas. An efficient in vitro multiplication protocol is one of the options to meet the planting material requirement. Effects of carbon source (glucose, fructose and sucrose) and concentration (1 and 3%, w/v), cytokinins (BAP and meta topolin) and concentration (1 mg/L and 2 mg/L), size of explants (one/ two/ three bud) and IBA treatment (0, 250, 500 and 1,000 mg/L) for concurrent ex vitro rooting cum hardening were studied. Results revealed that for facilitating efficient multiplication, the medium should be supplemented with glucose (3%) as a carbon source and meta topolin (1 mg/L) as cytokinin. Two-bud explant should be used for subculture as it promoted superior shoot proliferation. Concurrent ex vitro rooting cum hardening was possible even without auxin treatment. The present protocol could be useful for large-scale production of quality planting material of this underexploited tropical species.

ABSTRACTTherapeutic monoclonal antibodies (mAbs) represent one of the most important classes of pharmaceutical proteins to treat human diseases. Most are produced in cultured mammalian cells which is expensive, limiting their availability. Goats, striking a good balance between a relatively short generation time and copious milk yield, present an alternative platform for the cost-effective, flexible, large-scale production of therapeutic mAbs. Here, we focused on cetuximab, a mAb against epidermal growth factor receptor, that is commercially produced under the brand name Erbitux and approved for anti-cancer treatments. We generated several transgenic goat lines that produce cetuximab in their milk. Two lines were selected for detailed characterization. Both showed stable genotypes and cetuximab production levels of up to 10g/L. The mAb could be readily purified and showed improved characteristics compared to Erbitux. The goat-produced cetuximab (gCetuximab) lacked a highly immunogenic epitope that is part of Erbitux. Moreover, it showed enhanced binding to CD16 and increased antibody-dependent cell-dependent cytotoxicity compared to Erbitux. This indicates that these goats produce an improved cetuximab version with the potential for enhanced effectiveness and better safety profile compared to treatments with Erbitux. In addition, our study validates transgenic goats as an excellent platform for large-scale production of therapeutic mAbs.

Nanotechnology is an expanding area of research where we use to deal with the materials in Nano-dimension. The conventional procedures for synthesizing metal nanoparticles need to sophisticated and costly instruments or high-priced chemicals. Moreover, the techniques may not be environmentally safe. Therefore “green” technologies for synthesis of nanoparticles are always preferred which is simple, convenient, eco-friendly and cost effective. Green synthesis of nanoparticle is a novel way to synthesis nanoparticles by using biological sources. It is gaining attention due to its cost effective, ecofriendly and large scale production possibilities. Silver nanoparticles (AgNPs) are one of the most vital and fascinating nanomaterials among several metallic nanoparticles that are involved in biomedical applications. It has vital importance in nanoscience and naomedicines to treat and prevent vital disease in human beings especially in cancer treatment. In current work we discussed different methods for synthesis of AgNPs like biological, chemical and physical along with its characterization. We have also discussed vital importance of AgNPs to cure life threatnign diseases like cancer along with antidiabetic, antifungal, antiviral and antimicrobial alog with its molecular mode of action etc. Finally we conclude by discussing future prospects and possible applications of silver nano particles.

Embedded die substrate technologies are being developed in an assortment of configurations and for different market segments. The technology being discussed in this paper will be focused on both a fan out technology – ChipsetT Fan-Out and a system in package approach (ChipsetT SiP) in which a multiple component bill of materials (BOM) is used. The Chipset process is based on the WABE (Wafer and Board Level Embedding) technology. WABE technology is based on co-lamination of multilayer polyimide flex wiring and conductive z-axis sintered metal interconnections. This ChipsetT Fan Out technology allows for large scale production of fan out type solutions which can allow for very thin packages in addition to unique pin out solutions such as pin compatibility for a competitor part. The ChipsetT SiP also allows embedding of single or multiple silicon die and/or components. Additional components can also be placed using conventional SMT on the top or bottom side of the package. There is a great deal of design flexibility with this technology which makes it a great solution for applications trying to reduce their x-y size or z-height. When utilizing RDL technology on the embedded die we are able to do the fine pitch routing in order to allow the substrate to route at larger pitches ensuring an overall cost effective solution. This paper will focus on the different classes of applications that have benefited from this technology and will discuss the benefits and tradeoffs of the different solutions that have been engineered. Assembly and reliability data will be presented on several of the applications showing a robust solution set.
