Extranodal NK/T lymphoma, nasal type, is an uncommon neoplasm that occurs with a higher prevalence among Asian populations and Native American populations of Central and Southern America. In Western countries, this tumor is extremely rare, accounting for less than 1.5% of all non-Hodgkin lymphomas. Cytogenetic analyses have been performed only ...

Cytogenetic analysis has transformed the management of uveal melanoma in recent years and allows categorization of such tumors into low-grade tumors with a favorable prognosis and high-grade tumors that metastasize with a fatal outcome. The authors report the case of a 73-year-old man who presented with recurrent melanoma in his ...

We generated FM7a and CyO balancer chromosomes bearing a Tubby1 (Tb1) dominant transgene. Flies heterozygous for these FM7a and CyO derivatives exhibit a phenotype undistinguishable from that elicited by the Tb1 mutation associated with the TM6B balancer. We tested two of these Tb-bearing balancers (FM7-TbA and CyO-TbA) for more than ...

We describe two siblings with generalized hypotonia, expressive language delay, developmental delay, mild facial dysmorphism, and accelerated growth. In addition, the male sibling had testis dysgenesis. Cytogenetic evaluation revealed an unbalanced maternally inherited translocation t(15;22)(q26;q13.3) resulting in partial monosomy 22q and trisomy 15q. The combination of deletion 22q and duplication ...

To perform linkage analysis on an inbred family with members who exhibit different phenotypic forms of childhood strabismus. Prospective clinical examination and linkage analysis. THREE OF THE TEN SIBLINGS AND THEIR COUSIN EACH HAD A DIFFERENT PHENOTYPIC FORM OF CHILDHOOD STRABISMUS: infantile esotropia with convergence excess, esotropia associated with anisometropic ...

This paper reports on the most important recent technological event and its significance to the human race: chromallocyte designed by Robert Freitas--a nanorobot that would be capable of replacing chromosomes on a cell by cell basis throughout the body in vivo. The significance of chromallocyte comes from its ability to ...

Lipomas of the small intestine are usually found incidentally; symptoms occur in less than one-third of affected patients, especially when lipomas are more than 2 cm in size. We report a 32-year-old man in whom intestinal lipomatosis resulted in colo-colic intussusception. These symptoms disappeared following operative resection of about 60 ...

Deficiency of the endoplasmic reticulum enzyme dolichyl-phosphate mannose (Dol-P-Man):Man(7)GlcNAc(2)-PP-dolichyl mannosyltransferase leads to a new type of congenital disorder of glycosylation, designated type Ig. The patient 1 presented with a multisystemic disorder with microcephaly, developmental retardation, convulsions and dysmorphic signs. The isoelectric focusing pattern of the patient's serum transferrin showed the ...

Lubag (X-linked dystonia-parkinsonism) has been considered a sex-linked recessive trait and has been mapped to the pericentromeric region of the X chromosome. We studied a 54-year-old man with lubag and two of his female first cousins. Genetic typing was carried out using X chromosome markers. Fluorodopa PET was performed on ...

Five new oleanane saponins named arganine A, B, D, E and F and two known saponins: arganine C and mi-saponin A were isolated from the kernel of Argania spinosa. The structures of these saponins were elucidated by using 1H NMR, 1H-1H COSY NMR, 13C NMR, FAB mass spectrometry and chemical ...

A 34-year-old man and a 71-year-old woman underwent radical removal of mediastinally sited chondrosarcoma, presumably originating in the periosteum of the vertebral body. The man (with mesenchymal chondrosarcoma) died of remote metastasis 6 years postoperatively. The woman (poorly differentiated chondrosarcoma, grade 2-3) is still alive 2 years after the operation.

This paper describes the complex psychotherapy of a young man involved with white witchcraft and a coven of white witches during crucial phases of therapeutically activated processes of separation-individuation. Psychoanalytic concepts are applied toward a theoretical and technical understanding of such a unique therapy and of white witchcraft in general.

Man, gorilla, and chimpanzee likely shared an ancestor in whom the fine genetic organization of chromosomes was similar to that of present man. A comparative analysis of high-resolution chromosomes from orangutan, gorilla, chimpanzee, and man suggests that 18 or 23 pairs of chromosomes of modern man are virtually identical to ...

The relative DNA contents of individual chromosomes of Sminthopsis crassicaudata (Marsupialia) have been measured by DNA cytophotometry. Measurements of the relative nuclear DNA contents of man and Sminthopsis have been made and show that the DNA content of the marsupial X chromosome is substantially less than that of the X ...

A simple procedure for extracting a lectin from the seeds of the jackfruit, Artocarpus integrifolia, is described. The extracts had an average protein concentration of 13.3 mg/ml, and were strongly erythroagglutinating with a 10(6) titre. Erythroagglutination was shown to be non-specific for A1-B-0 erythrocytes. Lymphoblastic transformation and mitogenic stimulation occurred ...

This paper deals with a well-preserved human cranium of late Middle Pleistocene, belonging to a young male individual. It has many characters identical to those of early Homo sapiens or intermediate between Homo erectus and modern man. It possesses also some features similar to those of modern man, and close ...

Genetic evidence for a dimeric structure of dihydropteridine reductase in man and in the fish species "Cheirodon axelrodi" and "Salmo irideus" is presented. A single locus in man and two loci in the fishes examined encode this enzyme. Zymograms revealed two alleles for the locus in man and two alleles ...

The karyotype of a platyrrhine, Cebus capucinus, is compared with that of man and other catarrhines. It was found that a large degree of analogy of chromosome banding exists among the different species. A common origin for the platyrrhines and the catarrhines can thus be deduced. Furthermore, it becomes possible ...

CBA/N mice carry an X-linked recessive defect expressed in cells of the B cell lineage. The major deficiency in these mice is an almost complete inability to respond to certain thymus-independent antigens, such as pneumococcal polysaccharide type III (S III). We have examined the responses of mice carrying the CBA/N ...

The yield of chromosomal aberrations induced by exposure to X-irradiation in vitro was studied in the lymphocytes of the chimpanzee (Pan troglodytes), a hominoid ape phylogenically and chromosomally closely related to man. In agreement with the similarity of the chromosome characteristics, no significant difference was observed between man and chimpanzee ...

Recently developed pachytene maps of the two small acrocentric autosomes (numbers 21 and 22) of man have been applied to a case of Down's syndrome mosaic for normal and trisomic cells (46,XY/47,XY,21+). Trivalents in trisomic spermatocytes, and thus the supernumerary chromosome, were recognized as compatible in length and chromomere pattern ...

Eight different flavone C-glycosides from Mnium affine were tentatively identified by chromatography and spectroscopy. Quercetin-3-diglycoside and other unidentified flavonoids were found in M. arizonicum. The fiavonoid chemistry standing of its systematics.

Field trials of acrolein for the simultaneous control of aquatic weeds and snails were conducted in the Sudan.Phytotoxicity studies at 25 and 50 ppm showed minor or no damage to furrow-irrigated crops, but flood irrigation of vegetable seedlings at 15 ppm was toxic.Effective downstream carriage of acrolein was demonstrated for ...
