Cytogenetic Studies on Some Kashmir Grasses. VIII. Tribe Agrostideae, Festuceae and Paniceae.

Cytogenetic Activity Studies on Some Mangroves of Krishna–godavari Estuary

In the present study the bark of Ceriops decandra, collected from godavari estuary, Ceriops tagal and Xylocapus molluccensis collected from Krishna estuary of hexane, methylene chloride and methanol extracts were evaluated for Genotoxicity and cytotoxicity effects. The results indicated that the extracts from the all the three mangrove plant species have cyto-toxicity and it is substantiated fr...

Impact of cytogenetic and molecular cytogenetic studies on hematologic malignancies.

Conventional cytogenetic analysis of chromosome abnormalities in hematologic malignancies is hampered by the low mitotic index and poor quality of metaphases. A range of techniques based on fluorescence in situ hybridization (FISH) has greatly enhanced the identification of non-random translocations and deletions, pinpointing regions which contain genes involved in leukemogenesis. One of the ma...

Notes on Some Remedies. VIII. Amœbicides

Cytogenetic studies on Gonatodes (Reptilia, Squamata, Sphaerodactylidae).

Mitotic and meiotic chromosomes of 5 species of the reptile genus Gonatodes are described by means of conventional staining, banding analyses and in situ hybridization using a synthetic telomeric DNA probe. The amount, location and fluorochrome affinities of constitutive heterochromatin, the number and positions of nucleolus organizer regions, and the patterns of telomeric DNA sequences were de...

In Vivo Cytogenetic Studies on Aspartame

Aspartame (a-Laspartyl-L-phenylalanine 1-methylester) is a dipeptide low-calorie artificial sweetener that is widely used as a nonnutritive sweetener in foods and drinks. The safety of aspartame and its metabolic breakdown products (phenylalanine, aspartic acid and methanol) was investigated in vivo using chromosomal aberration (CA) test and sister chromatid exchange (SCE) test in the bone marr...
