    Notes:
    The optical and structural characteristics of GaN films implanted with Mg and Be ions, grown by low-pressure metalorganic chemical vapor deposition were studied. The low temperature (20 K) photoluminescence (PL) spectra of annealed Mg implanted GaN show a 356 nm near band edge emission, a 378 nm donor-acceptor (D-A) transition with phonon replicas, and a 528 nm green band deep level emission. The origin of the 528 nm green band emission and the 378 nm D-A emission might be attributed, respectively, to the Mg implantation induced clustering defect and the vacancy defect in GaN film. Observations of in-plane and out-of-plane x-ray diffraction spectra for as-grown undoped, Mg implanted and rapid thermal annealed GaN suggest that ion implantation induced anisotropic strain may be responsible for the observed PL emission characteristics. © 1998 American Institute of Physics.

    Notes:
    Summary Resistant (R) and susceptible (S) biotypes of Eleusine indica were collected from four areas, namely Chaah, Lenggeng, Bidor and Temerloh, in Malaysia. Restriction fragment length polymorphism (RFLP) and polymerase chain reaction (PCR)-RFLP analyses using SphI restriction enzyme were able to differentiate the R biotype from the S biotype by showing R-specific and S-specific polymorphisms in E. indica from three of the areas, with the exception of Temerloh where no polymorphisms were detected. The different DNA profiles for the R biotypes obtained indicate that SphI is not a useful diagnostic marker. The DNA polymorphisms detected in the 5-enolpyruvylshikimate 3-phosphate (EPSP) synthase gene suggest that there are different mutation events leading to development of resistance to glyphosate. Partial sequencing of the EPSP synthase gene confirmed different mutations occurring with substitution of proline with serine or threonine at amino acid 106 for the R biotype in Chaah, Bidor and Temerloh.

    Notes:
    Collagenolytic enzymes released by neutrophils are associated with the destruction of periodontium in periodontal diseases. Measurement of these enzymes in gingival crevicular fluid (GCF) could be used to test for periodontal diseases and thereby simplify diagnosis. To test this hypothesis, gelatinase (MMP-9) was analyzed in GCF samples with a simple assay system. GCF was collected by a mouthrinse method from 10 patients with gingivitis (G); 10 well-treated and maintained periodontitis patients (TP) without detectable loss of attachment; and 9 patients with recurrent loss of periodontal attachment (〉2 mm) and/or abscess formation (RP). Clinical measurements including tooth mobility (MOB) and gingival attachment level (GAL) were made monthly for a maximum of 10 months. Active and latent forms of gelatinase were measured by a functional assay using gelatin substrate-gel enzymography and the activities were quantified by laser densitometry. Reproducibility analysis demonstrated that the assay (inter-gel, inter-assay, inter-scan) and diurnal variations were small compared to biological variation. The presence of active gelatinase was detected in 97.8% of TP samples, 86.4% of RP samples, but in only 11.4% of G samples. In addition, the mean active gelatinase activity was found to be significantly higher (p〈0.001) in the RP (71 006 U) than the TP (43814 U) groups, both of which were higher (p〈 0.001) than the G group (2824 U). During periods of attachment loss, samples from the RP group exhibited a 2-fold increase of mean active gelatinase activity (129414 U). Correlation and regression analyses demonstrated that active gelatinase activity was most strongly associated with loss of GAL (r = 0.52, p〈0.0001) and to a lesser degree with mean MOB (r = 0.35, p〈0.03). However, neither total (latent plus active) nor latent gelatinase levels were associated closely with any clinical parameters of periodontitis. Metronidazole treatment (250 mg, tid, for 7 days) of RP patients significantly reduced the level of active and latent gelatinase 4- to 6-fold (p〈 0.002). These data indicate that measurement of active gelatinase in mouthrinse samples may provide a simple and robust diagnostic test for periodontal diseases and for assessment of treatment response.

    Notes:
    Summary Malaysians of Malay, Chinese, and Indian ancestries were electrophoretically phenotyped for Amy1 and saliva esterase region 1(Set-1) from saliva, Amy2 from plasma, soluble and mitochondrial GOT and PGM 3 from leukocyte and placenta. Kadazans and Bajaus, the indigenous people of Sabah, East Malaysia were surveyed for Amy2. Three types of variants were observed for Amy1, one type for Amy2. Only Indians were found to be polymorphic for Amy1. Two GOT s 2-1 and three GOT m 2-1 variants were found among 281 Chinese while three GOT m 2-1 variants were found among 311 Malays. Malaysian Malays, Chinese, and Indians were found to be polymorphic for Set-1 and PGM 3. The gene frequencies in Malays are Set-1F=0.601±0.021, Set-1S=0.399±0.021; PGM 3 1 =0.788±0.020, PGM 3 2 =0.212±0.020; in Chinese Set-1F=0.497±0.028, Set-1S=0.503±0.028; PGM 3 1 =0.745±0.024, PGM 3 2 =0.255±0.024; in Indians, Set-1F=0.449±0.031, Set-1S=0.551±0.031; PGM 3 1 =0.755±0.029, PGM 3 2 =0.245±0.029.

    Notes:
    Summary Human alcohol dehydrogenase ADH2 and ADH3 were investigated in liver and stomach specimens of Chinese and Indians from West Malaysia. Eight-nine percent of the Chinese carry the atypical ADH2 type, a proportion very similar to that reported in Japanese. However, among 43 Indian specimens there was not a single case of atypical ADH2. In Indians, the gene frequency of ADH3 1 is 0.64 and of ADH3 2 0.36, similar to the frequencies in Caucasians, whereas in Chinese, the gene frequency for ADH3 1 and ADH3 2 is 0.91 and 0.09, respectively. We also report some unusual enzymatic characteristics in the course of our study.

    Notes:
    Abstract Seasonal variation in water relations of 3-yearold white spruce (Picea glauca (Moench) Voss) shoots, monitored with pressure-volume curves over 28 months, was closely related to shoot phenology and was sensitive to environmental fluctuations during both summer growth and winter dormancy. Turgor maintenance capacity was lowest during rapid shoot elongation from late May to early July; this was indicated by the lowest total turgor pressures, the highest (least negative) osmotic potentials at full turgor and the turgor loss point, the smallest differences between osmotic potentials at full turgor and the turgor loss point, the highest relative water contents at turgor loss and a linear decline in cell elasticity with decreasing turgor pressure. This suggests that the high susceptibility of white spruce seedlings to growth check after transplanting is largely attributable to the poor turgor maintenance capacity of this species in early summer.

    Notes:
    Abstract Two separate human liver aldehyde dehydrogenases exist which show differences in substrate specificity, cation inhibition or activation, and molecular weight. In this paper we report a common absence of enzyme 2 in Chinese which may be taken to indicate a gene deletion coding for this enzyme. The possible implication of this gene deletion among Chinese is discussed.

    Summary Senoi and Aboriginal Malays of Peninsular Malaysia, surveyed for saliva acid phosphatases, amylase and superoxide dismutase, were polymorphic for Sap-A and Sap-B. Senoi were also polymorphic for SOD B. Malays, Chinese and Indians from Malaysia were phenotyped for SOD A and SOD B, using saliva. Though no SOD A variant was detected in any of the three racial groups, Malays and Indians showed rare variants for SOD B.

    Summary We surveyed three major ethnic groups in Malaysia for red cell glyoxalase I polymorphism. The allelic frequencies forGLO 1 were: Malays, 0.196; Chinese, 0.200; and Indians, 0.287. No rare variant was seen. By means of gel electrophoresis of placenta samples, theACON 2 s allele was found to be polymorphic in Chinese and Malays. The gene frequencies were 0.045 for Chinese and 0.039 for Malays. Only the commonACON s 1–1 phenotype was present among the 170 Indians we examined.

    Notes:
    Summary Indians appeared in Malaysia early in its history. Sustained contacts often resulted in racial admixture. We have analyzed the biochemical genetic markers phosphohexose isomerase (PHI), lactate dehydrogenase (LDH), adenylate kinase (AK), hemoglobin, rhesus blood group and haptoglobin (Hp) among Malays (the indigenous people of Peninsula Malaysia) and Indians to provide genetic evidence for racial admixture of these two groups. The occurrence of specific rare variants PHI 3-1, LDH Calcutta-1 and Madras-1, and Hb S, as well as the gene frequencies of adenylate kinase and haptoglobin in Malays and Indians confirm the gene flow from Indians to Malays.
