The Epidermal Growth Factor Receptor From Prostate Cells Is Dephosphorylated By A Prostate-Specific Phosphotyrosyl Phosphatase., Ming-Fong Lin, Gail M. Clinton
The Epidermal Growth Factor Receptor From Prostate Cells Is Dephosphorylated By A Prostate-Specific Phosphotyrosyl Phosphatase., Ming-Fong Lin, Gail M. Clinton
Journal Articles: Biochemistry & Molecular Biology
Human prostatic acid phosphatase (PAcP) has been found to have phosphotyrosyl-protein phosphatase activity (H. C. Li, J. Chernoff, L. B. Chen, and A. Kirschonbaun, Eur. J. Biochem. 138:45-51, 1984; M.-F. Lin and G. M. Clinton, Biochem. J. 235:351-357, 1986) and has been suggested to negatively regulate phosphotyrosine levels, at least in part, by inhibition of tyrosine protein kinase activity (M.-F. Lin and G. M. Clinton, Adv. Protein Phosphatases 4:199-228, 1987; M.-F. Lin, C. L. Lee, and G. M. Clinton, Mol. Cell. Biol. 6:4753-4757, 1986). We investigated the molecular interaction of PAcP with a specific tyrosine kinase, the epidermal growth factor …
Dual Mechanisms Of Regulation Of Type I Iodothyronine 5'-Deiodinase In The Rat Kidney, Liver, And Thyroid Gland. Implications For The Treatment Of Hyperthyroidism With Radiographic Contrast Agents., Donald L. St Germain
Dual Mechanisms Of Regulation Of Type I Iodothyronine 5'-Deiodinase In The Rat Kidney, Liver, And Thyroid Gland. Implications For The Treatment Of Hyperthyroidism With Radiographic Contrast Agents., Donald L. St Germain
Dartmouth Scholarship
Alterations in thyroid hormone status and the administration of radiographic contrast agents can markedly influence iodothyronine metabolism and, in particular, the activity of type I 5'-deiodinase (5'DI). In the present studies, the mechanisms responsible for these effects have been reassessed. As previously reported, the addition of iopanoic acid (IOP) to broken cell preparations resulted in a competitive pattern of 5'DI inhibition. However, the in vivo administration to rats of IOP or 3,3',5'-triiodothyronine (rT3) resulted in a noncompetitive pattern of inhibition of 5'DI in the liver, kidney, and thyroid gland, whereby marked decreases in maximal enzyme velocity (V max) were noted, …
Parentage Analysis With Genetic Markers In Natural Populations. I. The Expected Proportion Of Offspring With Unambiguous Paternity., R Chakraborty, T R Meagher, P E Smouse
Parentage Analysis With Genetic Markers In Natural Populations. I. The Expected Proportion Of Offspring With Unambiguous Paternity., R Chakraborty, T R Meagher, P E Smouse
Journal Articles
Recent studies indicate that polymorphic genetic markers are potentially helpful in resolving genealogical relationships among individuals in a natural population. Genetic data provide opportunities for paternity exclusion when genotypic incompatibilities are observed among individuals, and the present investigation examines the resolving power of genetic markers in unambiguous positive determination of paternity. Under the assumption that the mother for each offspring in a population is unambiguously known, an analytical expression for the fraction of males excluded from paternity is derived for the case where males and females may be derived from two different gene pools. This theoretical formulation can also be …
The Dental Health Of Factory Workers In Pasir Gudang, Johor (Malaysia), Abdul Majid Z., Rosnah Binti Zain
The Dental Health Of Factory Workers In Pasir Gudang, Johor (Malaysia), Abdul Majid Z., Rosnah Binti Zain
Prof. Dr. Rosnah Binti Zain
A study on the oral health status of 198 factory workers (in Antara Steel, Pasir Gudang, Johor) was carried out in November 1986. The subjects were predominantly male (94%) and Malay (91%) with an average age of 27.4 years. The prevalence of caries was 87.4% with a mean DMFT of 7.1 + 5.4. There were 3 subjects with full upper, lower dentures and 16 subjects with partial dentures. Two subjects examined needed dentures but were not wearing them. Thirty five (17.7%) of those examined needed urgent extractions, and 8 needed emergency treatment for fillings. Enamel opacities were found in 141 …
The Cracked Tooth Syndrome--Crown Root Vertical Fracture, Rosnah Binti Zain, Majid Z. A.
The Cracked Tooth Syndrome--Crown Root Vertical Fracture, Rosnah Binti Zain, Majid Z. A.
Prof. Dr. Rosnah Binti Zain
A case of an incomplete tooth fracture followed by a complete fracture was presented. The difficulty of diagnosing this condition was discussed as well as the possible histological explanation of the symptoms experienced by the patient. It once again points out to practising dentists, that whilst deep pockets can give rise to severe periodontal pain, intense and excruciating pain should be investigated with the cracked tooth in mind.
Peripheral Ossifying Fibroma/Ossifying Fibrous Epulis, Rosnah Binti Zain, Janakarajah N.
Peripheral Ossifying Fibroma/Ossifying Fibrous Epulis, Rosnah Binti Zain, Janakarajah N.
Prof. Dr. Rosnah Binti Zain
This is a case report of a reactive lesion which occurs only in the gingiva. This lesion is of a long duration causing erosion of the superficial bone. Histologically it is similar to other epulides of the gingiva but in addition contains ossified tissue. The lesion's confusing terminology is being discussed in view of its understanding to an American-trained or a British-trained surgeon. A review of literature showed a recurrence rate of 7-20% thus making it mandatory for a close follow-up of the patient.
