Early treatment of skeletal Class III: a case report.

Skeletal class III malocclusion is a growth related facial deformity which increases if left untreated. Skeletal class III malocclusion should be corrected as soon one recognises the initial signs. Mixed dentition period is the time of greatest opportunity for occlusal guidance and growth modulation. A case of skeletal class III malocclusion in mixed dentition is presented, which was treated with a Delaire face mask therapy to modulate the craniofacial growth and to achieve a balanced profile.

Maxillary expansion--an interceptive modality in mixed dentition.

Maxillary expansion is a very useful procedure for arch length augmentation, posterior crossbite treatment and removing cross arch interferences. Removable appliances are in the realm of a pedodontist and general dentist. However, one should be aware of the problems arising at an early age of the child, should be able to properly diagnose the condition and if required, a timely referral to a specialist is also expected.

Early body weight of five strains of White Leghorn.

1. The means, standard errors and coefficients of variation for body weight at fortnightly intervals from day 1 to day 90 of five indigenous strains of White Leghorn were estimated. 2. The differences between the strain and body weight were significant at all ages while the differences between sex were significant from day 45. 3. Phenotypic correlations between body weight at day 1 with that of day 30, 60 and 90 were 0-237, -0-007 and -0.07. 4. The heritability by paternal half-sib method ranged from 0-32 to 0-54 for body weights from day 1 to day 90.

Radiation modifying effects of meso-tetraphenyl porphyrins.

The radiation modifying effects of a series of the metal chelates of meso-tetra(p-carboxyphenyl) porphine has been investigated using a human lymphoid cell line, RPMI 1788. These studies revealed that Ni and Zn porphyrins were effective radiation sensitizers at concentrations as low as 10-9M. Further studies with Zn porphyrin showed it to be almost equally effective when added immediately after irradiation and partially effective when added up to 90 minutes post irradiation, suggesting that it may be acting by interfering with a repair mechanism.
