The paper describes the prenatal ultrasonographic diagnosis of conjoined syncephalus-craniothoraco-omphalopagus twins at 13 weeks' gestation. The mother, after genetic counseling, decided to interrupt the pregnancy. The fetal karyotype, the maternal serum and amniotic fluid alpha-fetoprotein levels were normal. The diagnosis was confirmed by pathologic examination of the fetus after termination of pregnancy. 相似文献

We conducted a survey to determine parent-reported asthma prevalence, morbidity, and healthcare utilization among 3527 children attending public schools (n = 2849) and private schools (n = 678) in San Juan, Puerto Rico. Schools were randomly selected from each of 12 geographic regions of the San Juan metropolitan area. Parents of children age 4-7 years old completed a 12-item questionnaire on asthma diagnosis, respiratory symptoms and morbidity, and healthcare utilization. Parents of children in public schools and private schools reported similar rates of a physician having previously diagnosed asthma in their children (43.2% vs. 39.4%); however, significantly more children in public schools were reported to still have asthma at the time of the survey (32.6% vs. 23.7%). Children attending public schools vs. private schools were reported to have missed significantly more school and to have had more hospitalizations and emergency department visits. Among children reported to still have asthma, significantly more children visited an emergency department, were hospitalized, and missed more school days due to respiratory symptoms in the past year. The high prevalence of parent-reported asthma, respiratory symptoms, and healthcare utilization among Puerto Rican children in San Juan calls for further studies using objective methods for ascertaining asthma and asthma-related morbidity. Differences in healthcare utilization between children attending public vs. private schools suggest that socioeconomic factors play a role in asthma management in Puerto Rico. 相似文献

Summary In this study, we evaluated in normal subjects, insulin-dependent (IDD) and non-insulin-dependent (NIDD) diabetics, the diurnal
urinary C-peptide excretion rate (CPR-U) and its relationship to serum C-peptide concentration and glucose:C-peptide molar
ratio, and to the common parameters of metabolic control. The CPR-U (and CPR-U/g creatinine) were significantly lower in IDD
and higher in NIDD compared to control subjects. Moreover, a good and significant correlation with serum C-peptide concentrations
and the glucose:C-peptide ratio in diabetic subjects as well as in controls and diabetics considered together was found. A
slight but significant correlation was present in diabetic subjects between CPR-U and body mass index (r=0.45), 24-h glycosuria
(r=−0.36), HbA1 levels (r=−0.31), post-prandial glucose concentrations (r=−0.26) and per cent glucose variation after each
meal (r=−0.34). No differences were found in CPR-U and the degree of metabolic control between obese and non-obese NIDD. In
conclusion, CPR-U may be a useful and simple method of defining the secretory activity of the B-cell. Metabolic control in
diabetics is slightly correlated to the degree of B-cell function as evaluated by the diurnal excretion rate of C-peptide
in urine.

The beneficial effects of beetroot juice supplementation (BJS) have been tested during cycling, walking, and running. The purpose of the present study was to investigate whether BJS can also improve performance in swimmers. Fourteen moderately trained male master swimmers were recruited and underwent two incremental swimming tests randomly assigned in a pool during which workload, oxygen uptake (VO2), carbon dioxide production (VCO2), pulmonary ventilation (VE), and aerobic energy cost (AEC) of swimming were measured. One was a control swimming test (CSW) and the other a swimming test after six days of BJS (0.5l/day organic beetroot juice containing about 5.5 mmol of NO3−). Results show that workload at anaerobic threshold was significantly increased by BJS as compared to the CSW test (6.3 ± 1 and 6.7 ± 1.1 kg during the CSW and the BJS test respectively). Moreover, AEC was significantly reduced during the BJS test (1.9 ± 0.5 during the SW test vs. 1.7 ± 0.3 kcal·kg−1·h−1 during the BJS test). The other variables lacked a statistically significant effect with BJS. The present investigation provides evidence that BJS positively affects performance of swimmers as it reduces the AEC and increases the workload at anaerobic threshold. 相似文献

A new series of acridine based imidazolium salts was synthesized and evaluated for in vitro cytotoxicity against human cancer cell lines by an MTT assay. The synthesis applied a coupling of imidazoles with 9-chloroacridines, which originated from an Ullmann condensation of a 2-chloro-benzoic acid with an aniline. The target compounds were obtained in high yields. The DPPH assay indicated considerable antioxidant activity for target compounds with simple and short alkyl chains on the imidazole, while increasing chain length and the introduction of an additional π-electron system in most cases reduced the activity. All compounds exhibited low biotoxicity against non-cancerous cell lines, whereas a few compounds showed promising anticancer activity. Unlike for the reference drugs Tamoxifen and Paclitaxel, the anticancer activity of acridine imidazolium ions is specific for only selected cancer types. Reasonable fluorescent behaviour of the products provide potential for visualization of the distribution of active drugs in tissue.A series of acridine-based imidazolium salts was synthesized and studied on cytotoxicity against human cancer cell lines. 相似文献
