Small Ubiquitin-Like Modifier Protein 3 Enhances the Solubilization of Human Bone Morphogenetic Protein 2 in E. coli.

Small ubiquitin-like modifier (SUMO) fusion technology is widely used in the production of heterologous proteins from prokaryotic system to aid in protein solubilization and refolding. Due to an extensive clinical application of human bone morphogenetic protein 2 (hBMP2) in bone augmentation, total RNA was isolated from human gingival tissue and mature gene was amplified through RT-PCR, cloned (pET21a), sequence analyzed, and submitted to GenBank (Accession no. KF250425).

Haematological parameters and recurrent aphthous stomatitis.

Objective: To find out the relationship between recurrent aphthous stomatitis (RAS) with deficiencies of haemoglobin, haematocrit, serum vitamin B12, serum Ferritin and red blood cells (RBC) Folate level.

Study Design: An analytical cross-sectional study.

Place And Duration Of Study: Department of Oral Health Sciences, Shaikh Zayed Federal Postgraduate Medical Complex, Lahore, from February to July 2008.

Outcome of labour in nullipara at term with unengaged vertex.

Background: Primigravidas with unengaged foetal head at term should be regarded as high risk cases. It is seen that nuglliparous women with the floating foetal head demonstrate higher rates of caesarean section than those with dipping or engaged head in early labour. These cases should be regarded as high risk and identified early and should be referred to a tertiary care centre where good facilities for operative delivery are available.
