Synergistic effect of silver nitrate and coconut water on shoot differentiation and plant regeneration from cultured cotyledons of Capsicum annuum L.

Chili pepper (Capsicum annuum L.) ranks among the most important vegetable crop belonging to the family Solanaceae that is consumed both as vegetable and spice throughout the world. C.

Differential response of tomato and tobacco to Agrobacterium mediated transformation with cytokinin independent -1 (CKI-1) gene as influenced by cytokinin levels.

Cytokinin independent-1 (CKI-1) gene was identified through its ability to confer cytokinin independent growth in Arabidopsis which has led to this gene being advocated as a selectable marker in plant transformation. Keeping this in view, CKI-1 gene was assessed as a selectable marker by transformation of tobacco (Nicotiana tabacum) and tomato (Lycopersicon esculentum L.).

Ultrastructural characterization of the implant/bone interface of immediately loaded dental implants.

Primary stability and an optimized load transfer are assumed to account for an undisturbed osseointegration process of implants. Immediate loaded newly designed titanium dental implants inserted in the mandible of minipigs were used for the characterization of the interfacial area between the implant surface and the surrounding bone tissue during the early healing phase. Histological and electron microscopical studies were performed from implant containing bone specimens.

A novel method of isolation of a bone-morphogenetic-protein-like protein from ossein.

A new bone-morphogenetic-protein (BMP)-like protein has been isolated through a new protocol from a novel source, ossein. The BMP-like protein was hydrophilic and characterized through Fourier-transform IR studies, SDS/PAGE and coupled with a neutral binder, hydroxypropylmethylcellulose (HPMC) for control release. The IR spectrum of the protein showed peaks in tandem with BMP from bone matrix, and its molecular mass was in the range 18-21 kDa.

Preparation and characterization of a new bioinorganic composite: collagen and hydroxyapatite.

Studies on biomineralization in bone have opened new arenas in the field of fabrication and engineering of bone-graft devices. A new bioinorganic composite was prepared by introducing processed collagenous matrices into the calcifying solutions at pH 7.8-8.
