    Search for chromosomal variations among gas-exposed persons in Bhopal (1990)
    Springer
    Human genetics 〈Berlin〉 84 (1990), S. 172-176

    Thema: Biologie , Medizin
    Notizen: Summary A chromosomal survey using standard lymphocyte cultures employing different media and G-banding techniques was initiated in 1984. This study became particularly important following the tragic gaseous exposure of the population in Bhopal at midnight on 2 December 1984. We have been able to formulate a chromosomal profile for each person whom we have studied; during 1986–1988, 154 persons were examined twice. Among seemingly normal individuals, as many as 20% might possess some chromosomal abnormality; of these, 50% may develop, at a later date, some kind of pathological complication (such as tumours, recurrent abortion or transmission of defects to their offspring). The people exposed to methyl isocyanate have repeatedly shown Robertsonian translocations, mostly in acrocentric chromosomes 13 and 21. Other types of translocations have been studied among all exposed (53) and normal (101) persons; the involvement of chromosomes 5, 9, 11, 14 and 16 is statistically significant (P= 〈0.001). One of the major clinical symptoms is dyspnoea; we have estimated that almost all seriously dyspnoeic patients have developed at least two categories of chromosomal aberrations, one of which is Robertsonian translocation, in at least 10% metaphases. Our chromosomal survey will be of significance because we are able to identify people with chromosomal aberrations that might be correlated with future pathological consequences of the accident. The “chromosomal load” that can be sustained with an apparently normal phenotype can also be measured.

    Follicovitellosum indicum, a new trematode, found in the fish Belone belone (1972)
    Springer
    Marine biology 12 (1972), S. 99-102 
    Details
    ISSN: 1432-1793
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract A new trematode, collected in 1971 from Ratnagiri, India, is described as Follicovitellosum indicum sp. nov. A new subfamily, Follicovitellotrematinae is created within the family Zoogonidae Odhner, 1911, to receive the new genus Follicovitellosum, with its genotype F. indicum. The new species is characterized by the follicularized nature of its ovary; the ovarian follicles are posttesticular. The vitellarium is further divided into several follicles which are largely in the pre-ovarian zone, but post-acetabular and posttesticular in location.

    Thema: Biologie
    Notizen: Abstract A new digenetic trematode, collected 1969–1970 at Ratnagiri (India) from the marine eel Leptocephalus conger, is described as Indostomachicola kinnei n. g., n. sp. The new genus differs from Stomachicola Yamaguti, 1934 and Allostomachicola Yamaguti, 1958 in many characteristics. The new species is characterized by an unlobed ovary, absence of receptaculum seminis, and presence of post-acetabular seminal vesicle and a ventral pit.

    Zinc deficiency and pollen fertility in maize (Zea mays) (1990)

    Notizen: Abstract Zinc deficiency decreased pollen viability in maize (Zea mays L. cv. G2) grown in sand culture. On restoring normal zinc supply to zinc-deficient plants before the pollen mother cell stage of anther development, the vegetative yield of plants and pollen fertility could be recovered to a large extent, but the recovery treatment was not effective when given after the release of microspores from the tetrads. If zinc deficiency was induced prior to microsporogenesis it did not significantly affect vegetative yield and ovule fertility, but decreased the fertility of pollen grains, even of those which visibly appeared normal. If the deficiency was induced after the release of microspores from the tetrads, not only vegetative yield and ovule fertility but pollen fertility also remained unaffected.

    Characteristics of osteoarthritis among Kuwaitis: A hospital-based study (1998)

    Thema: Medizin
    Notizen: Abstract Sixty-nine Kuwaiti patients with osteoarthritis (OA) were studied. Primary knee OA was seen in 65 (94.2%) patients. The mean age of this group was 53.18 years with a range of 39–97 years. The female to male ratio was 2.82∶1. OA was bilateral in 84.62% and predominantly involved the medial tibiofemoral joint. According to Kellgren's grading of knee OA, grade 1 changes were present in 40.0%, grade 2 in 32.5%, grade 3 in 22.5% and grade 4 in 5.0%. Grade I obesity was seen in 13%, grade II in 64% and grade III in 23% of patients. Generalised primary nodular OA was seen in only four patients, all of whom were women. Primary OA of the hip joint and chondrocalcinosis were conspicuous by their absence.

    Manganese deficiency in maize affects pollen viability (1991)
    Springer
    Plant and soil 138 (1991), S. 139-142

    ISSN: 1573-5036
    Schlagwort(e): maize ; manganese deficiency ; pollen viability

    Notizen: Abstract Maize (Zea mays L. cv. G2) was grown with 0.55 mg L−1 (sufficient), or 0.0055 mg L−1 (deficient) manganese in sand. Manganese-deficient plants developed visible deficiency symptoms and showed poor tasseling and delayed anther development. Compared to Mn-sufficient plants, Mn-deficient plants produced fewer and smaller pollen grains with reduced cytoplasmic contents. Manganese deficiency reduced in vitro germination of pollen grains significantly. Ovule fertility was not significantly affected by Mn. But in Mn-deficient plants seed-setting and development was reduced significantly.

    Histochemical studies on the distribution of alkaline phosphatase, acid phosphatase, 5-nucleotidase and ATPase in various reproductive tissues of certain digenetic trematodes (1976)
    Springer
    Parasitology research 49 (1976), S. 223-231 
    Details
    ISSN: 1432-1955
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Medizin
    Notizen: Summary Out of other functions performed by vitellaria in digenetic trematodes, their role in the formation of shell globules and shell membrane of the capsule, as well as in the excretion of iron with the help of vitamin C is very important. The present histochemical work shows the localization of certain enzymes in different parts of the reproductive system of ten species of trematodes viz.: Neopronocephalus triangularis Mehra, 1932; Glossimetra orientalis Mehra, 1937; Orientodiscus lobatus Srivastava, 1938; Eumegacetes artemii Mehra, 1935; Ganeo tigrinus Mehra et Negi, 1928; Encyclometra caudata Dollfus, 1928; Thapariella udaipurensis Gupta and Sharma, 1970; Paradistomoides indicum Narain et Das, 1929; Patagifer wesleyi Verma, 1936; Proalarioides tropidonotus Vidyarthi, 1937 and indicates their functional significance. The hydrolytic enzymes (alkaline phosphatase, acid phosphatase, 5-nucleotidase and ATPase) are suggestive of their involvement in the uptake of certain nutrients, glycogen and lipoprotein being very significant among others. The four enzymes could also be detected in testes, ovary, uterus, cirrus sac and egg shell. The possible functional significance of each enzyme has been discussed.

    Konstitution von Jodsäure. III (1939)

    Notizen: Die Untersuchung verschiedener physikalischer Eigenschaften von wäßrigen Jodsäurelösungen wird im einzelnen beschrieben. Durch Anwendung der Mischungsgleichung zur Eliminierung des Lösungsmitteleinflusses werden Kurven über die Abhängigkeit der untersuchten physikalischen Eigenschaft von der Konzentration der Lösung erhalten, die bei 0,1 n und 0,04 n Knicke bzw. Unstetigkeiten aufweisen. Alle Kurven ergeben praktisch das gleiche Bild. Diese Unstetigkeiten werden in der Weise gedeutet, daß bei den genannten Konzentrationen eine Depolymerisation von (HJO3)3 unter Bildung einfacher Moleküle eintritt, wahrscheinlich der Übergang (HJO3)3 → (HJO3)2 → (HJO3). Eine Prüfung der Ramanspektren bestätigte diesen Befund.
