Iraqi-Jewish optic atrophy plus is an autosomal recessive condition characterized by infantile optic atrophy, an early onset movement disorder, and 3-methylglutaconic aciduria. Other features include spastic paraplegia, mild ataxia, mild cognitive deficiency and dysarthria. This disorder was identified in inbred Iraqi-Jewish kindreds in which relationships between most of the affected individuals were unknown. In this study we identify linkage to chromosome 19q13.2-q13.3 by using a DNA pooling strategy to perform a genome wide screen followed by a high density search for shared segments among affected individuals in candidate regions identified in the initial genome wide screen. A significantly high positive lod score of 6.14 at zero recombination was obtained for the CTG repeat in the 3' untranslated region of the myotonic dystrophy protein kinase gene. The existence of multiple recombinant individuals indicates the disease interval can be further narrowed with additional markers. Linkage disequilibrium was seen in six polymorphic markers across a 1 Mb interval. This region is well characterized and contains several candidate genes. 相似文献

The role of apitherapy in the combined treatment of patients with chronic nonspecific lung diseases]
The authors suggest that apitherapy should be used in the treatment of patients with chronic non-specific pulmonary diseases (ChNPD) in order that it might be more effective. Apitherapeutic complex (bee venom and bee keeping apiculture produce) has been applied to the treatment of 104 ChNPD patients. High effectiveness of apitherapy in a combined treatment of ChNPD patients was demonstrated as was their stimulating and normalizing influence on the function of the adrenals. 相似文献

Studied by endoscopy were 100 adolescents with diagnosed duodenal ulcer, as were 100 essentially healthy subjects and 90 ones of the same age presenting with primary chronic gastroduodenitis together with 60 adults who had duodenal ulcer. The following items were etiologic risk factors for duodenal ulcer, if combined, in the above adolescent series: Frequent episodes nervous of tension, hereditary predisposition and helicobacteriosis. In juveniles with duodenal ulcer, secretion and motility of the stomach appeared to be subjected to changes to a higher degree than it was in adult subjects with duodenal ulcer, while functions of the psychovegetative and immune systems were found to be less changeable in the former. In adolescents presenting with duodenal ulcer and primary chronic gastroduodenitis, the etiologic risk factors and pathogenetic changes were found out to be identical. 相似文献

The structural and phase transitions in formation of anhydrous MMO during vacuum drying of DH-MMO and MH-MMO were investigated.
The characteristics of the structural changes in MH-MMO in repeated processing of the sample in a heating-cooling regime were
determined.

A cDNA encoding farnesyl diphosphate (FPP) synthase (FPPS) has been cloned from a cDNA library of Artemisia annua. The sequence analysis showed that the cDNA encoded a protein of 343 amino acid (aa) residues with a calculated molecular weight of 39420 kDa. The deduced aa sequence of the cDNA was highly similar to FPPS from other plants, yeast and mammals, and contained the two conserved domains found in polyprenyl synthases including FPPS, geranylgeranyl diphosphate synthases and hexaprenyl diphosphate synthases. The expression of the cDNA in Escherichia coli showed enzyme activity for FPPS in vitro. 相似文献

BACKGROUND: The study was conducted to determine the influences of laparoscopy in the management and outcome of patients with appendicitis. METHODS: A retrospective analysis of 154 consecutive patients who were treated for suspected appendicitis. The pre-operative diagnosis included appendicitis, right lower quadrant pain of unknown etiology, and generalized peritonitis. RESULTS: Laparoscopy was used in 108 patients, including 70 laparoscopic appendectomies (LA) and 31 LAs converted to open appendectomy (OA). Forty-six patients had OA. The average operating time for LA was 74.3 minutes and 48.8 minutes with OA. Postoperative complications for LA (7%) included 1 trochar wound hemorrhage, 2 wound infections, and 2 intra-abdominal sepsis; and for OA (9%) were 1 post-operative intra-abdominal hemorrhage, 4 wound infections, 1 wound dehiscence, and 1 intra-abdominal sepsis. Post-operative stay for LA averaged 2.5 days and for OA averaged 4.5 days (P = .0049). LA patients had a considerably faster return to work and/or normal activity than OA patients (P = .00065). CONCLUSIONS: Laparoscopy influenced the management of 29% of patients presenting with suspected appendicitis. LA resulted in shorter hospitalization and a more rapid return to work and/or normal activity than OA. 相似文献
