ABSTRACT

Achieving an appropriate DHA status in the neonatal brain is an important goal of neonatal nutrition. We evaluated how alpha-linolenic acid (ALA), provided for six weeks after weaning by different dietary fat matrix, improved brain DHA content of young male rats born from deficient-dams. The level of ALA achieved was based on the fat composition of usual infant vegetable formula. A palm oil-blend diet thus providing 1.5%ALA was compared to dairy fat-blend-based diets that provided either 1.5%ALA or 2.3%ALA, or a rapeseed oil diet providing 8.3%ALA (n-6/n-3 ratio were, respectively 10,10,5,2.5). The 1.5%ALA-dairy-fat-blend was superior to 1.5%ALA-palm-oil-blend to restore values of brain DHA, while the 2.3%ALA-dairy-fat-blend exhibited a further increase and reached the values obtained with pure rapeseed diet (8.3%ALA). Dairy-fat-blends enriched with ALA appear to be an interesting strategy for achieving optimal DHA levels in the brain of post-weaning rats. Providing dairy fat as well as a reduction of the LA/ALA ratio should be reconsidered to design infant formula.

ABSTRACT

Populations of Western countries are severely deficient in omega-3 intake, both in the form of alpha-linolenic acid (ALA) and the Long Chain derivatives (LC-n-3), Eicosa-Pentaenoic-Acid and Docosa-Hexaenoic-Acid. Omega-3 insufficiency is a risk factor for cardiovascular and cerebral diseases such as coronary heart disease and stroke. Stroke is a major cause of mortality and morbidity, and induces a significant socioeconomic cost and a marked increase in patient/family burden. To date, preventive treatments and neuroprotective drugs identified in preclinical studies failed in clinical trials, in part because of an inability to tolerate drugs at neuroprotective concentrations. Therefore testing alternative protective strategies, such as functional foods/nutraceuticals, are of considerable interest. We have previously demonstrated that a single injection of ALA reduced ischemic damage by limiting glutamate-mediated neuronal death, whereas repeated injections displayed additive protective benefits as a result of increased neurogenesis, synaptogenesis and neurotrophin expression. Because intravenous injections are not a suitable long-term strategy in humans, the present study investigated the effect of ALA supplementation by an experimental diet containing rapeseed oil (RSO, a rich source of ALA) as the only source of lipids for stroke prevention. We tested several experimental diets which included 5, 10, and 20% RSO-enriched diet and feeding paradigms (fresh diet was provided once or twice a week for 4 or 6 weeks). Our results showed that ALA supplemented diets are more sensitive to lipid peroxidation than a regular chow diet. Because the diet affected feeding behavior and animal growth, we defined concrete guidelines to investigate the effect of omega-3 supplementation on neuropathology. Among the different sets of experiments, animals fed with 10% and 20% RSO-enriched diet displayed a reduced mortality rate, infarct size and increased probability of spontaneous reperfusion in the post-ischemic period. In addition, a drastic reduction of lipid peroxidation levels was observed in the ischemic brain of RSO-fed animals. Overall, our findings provide new insights into the potential of employing rapeseed oil as a functional food/nutraceutical aiding in stroke prevention and protection.

ABSTRACT

The goal of the treatment of infertility is to apply therapeutic techniques to patients in a safe manner and at the same time increase the chances for conceiving and delivering healthy babies: basic and clinical research is more and more finalized directed to these goals. The conference "Advances in Infertility Treatment" held in Fort Lauderdale, Florida on January 24-26, 2002 covered many clinical and research aspects of this important therapeutic area. Important discussed issues included the impact of age, lifestyle, and the genetic set-up of patients in the pathogenesis and development of infertility-causing disorders such as male reproductive dysfunction, polycystic ovary syndrome, and ovarian failure. New ovulation induction regimens that may optimize, reduce complications, and lower costs of ovarian stimulation procedures and of assisted reproduction in general were presented. This was the 5th Ferring Pharmaceuticals Conference in the area of reproductive medicine held in Florida.

ABSTRACT

In France, many couples in procreating age continue to smoke, despite recommendations to stop smoking before or during pregnancy. We reviewed the epidemiological associations between maternal or paternal smoking and both infertility and very preterm birth. It appears clearly that maternal smoking impairs natural and assisted fecundity. Furthermore, maternal smoking enhances the rate of ectopic pregnancies and spontaneous abortions. The role of maternal smoking on very preterm birth before 33 weeks of completed gestation appears in recent population based-study or case-control studies that include several hundred very preterm neonates. But the role of smoking on very preterm birth among hypertensive mothers and primiparae is still debated. The detrimental effect of smoking on fecundity appears to be reversible when the mother and father stop smoking. The real effect of interventions promoting cessation of smoking during pregnancy in reducing the rate of very preterm births remains to be studied.

ABSTRACT

We investigated the target structures of the epithelial cells responsible for the attachment of Porphyromonas gingivalis by immunocytofluorimetry, enzyme-linked immunosorbent assay, and confocal microscopy. Integrins (beta1, beta3, and alphaV) and E-cadherin played no significant role. Carbohydrates (such as alpha-D-methylglucoside, L-fucose, D- and L-mannose, N-acetylglucosamine, and N-acetylgalactosamine) had little inhibitory effect on bacterial binding. Enzymatic treatments of the epithelial membranes and sugar competition studies showed that N-acetylneuraminic acid and glucuronic acid were involved in binding.

ABSTRACT

Septic peri-implantitis is the main clinical complication encountered following the insertion of titanium implants. It may be resistant to conventional antibiotic treatments. Reports in the literature about antibiotic behavior in the presence of titanium remain controversial. They vary from a bacteriostat to a decreased effect of antibiotic. This study examined, in vitro, the viability of Porphyromonas gingivalis, frequently associated with periodontal diseases, in the presence of titanium and antibiotics (spiramycin and metronidazole alone or in combination). Viability of P. gingivalis was determined, versus a standard curve using the Live/dead Baclight Bacteria Viability Kit on 96 well microplates. The results of 48 experiments (60 measurements each) were compiled in a database and compared to each other using the chi2p < 0.05 test. When used alone, titanium enhanced bacterial growth as the nickel-chrome control. However, when titanium was used in the presence of antibiotics, antibiotics kept their own effects. Even more, titanium was shown to potentialize the effect of metronidazole. The strengthening of effectiveness of metronidazole by titanium may be due to the oxidation potential of the metal. This chemical property could explain the conflicting data reported in the literature.

ABSTRACT

The retention and survival of microorganisms on toothbrushes pose a threat of recontamination for certain patients at risk. In order to measure the influence of brush design and optimize the choice of toothbrush model for complementary studies, the in vitro retention of three microbial species (Porphyromonas gingivalis ATCC 33277, Streptococcus mutans ATCC 25175 and Candida albicans ATCC 26555) was evaluated for three types of toothbrush. Two series of standardized experiments were carried out for each brush and microorganism. The first series tested the retention of the microorganisms on the head portion of the brush, while the second measured retention on the head of the brush and the part of the handle inserted in the mouth during brushing. For each series, the microorganisms were counted at T0 and T24 (after storage of the brushes at room temperature for 24 h). Depending on the microorganism studied, from 0.2% to 2% of the initial inoculum was retained on the brush. The number detected increased with the size of the exposed area. After 24 h, P. gingivalis and S. mutans were found on only one type of brush. C. albicans survived on all three. These results confirm that microorganisms can quickly colonize toothbrushes.

ABSTRACT

The protein profiles of Porphyromonas gingivalis (ATCC 33277 and W83) bound to KB gingival epithelial cells were analyzed by SDS-PAGE and immunoblotting. We found that a 51-kDa component was formed in bacteria that adhered to the KB cells, whereas 26- to 29-kDa bands were less intensive, in contrast to the protein profile of free bacteria. P. gingivalis ATCC 33277 incubated with protease-treated KB cells retained the profile of free bacteria. These results demonstrate the specificity of bacterial recognition of eukaryotic membrane components.

ABSTRACT

OBJECTIVE: The aim of our study was to determine if the assessment of pulmonary vascularization by energy color Doppler during ultrasound examination can predict the absence of pulmonary hypoplasia before birth in situations where it is a high risk. METHODS: In a prospective study of 12 pregnancies presenting a risk of pulmonary hypoplasia (5 early and prolonged premature ruptures of the membranes, 1 diaphragmatic hernia, 1 chylothorax, 1 pulmonary sequestration, 1 omphalocele, 1 anamnios and 2 Potter's syndromes) energy color Doppler was used to visualize pulmonary vascularization. RESULTS: In 10 cases where pulmonary vascularization could be visualized, none of the infants had pulmonary hypoplasia. In the 2 cases of Potter's syndrome where pulmonary vascularization was not visualized there was a pulmonary hypoplasia. CONCLUSION: The visualization of fetal pulmonary vascularization with energy color Doppler in situations with a high risk of pulmonary hypoplasia can predict the absence of severe pulmonary hypoplasia.

ABSTRACT

Because the down-regulation by progesterone of cystic fibrosis transmembrane conductance regulator (CFTR) expression could be a useful specific marker to define the state of implant receptivity in endometrium, a competitive reverse transcription-polymerase chain reaction (RT-PCR) was developed for quantifying the CFTR mRNA concentration in human endometrial samples. A competitor RNA was constructed with the same sequence as the CFTR sequence except for a 20-nucleotide insertion in the middle. The amplified products were separated by polyacrylamide gel electrophoresis. The ratio of CFTR band areas to competitor band areas provided the basis of quantification. Using this competitive RT-PCR, we measured CFTR mRNA in human endometrial samples taken at different periods of the menstrual cycle, in endometriosis, and in hyperplasia. Results show that the method is suitable for measuring the concentration of CFTR mRNA.

ABSTRACT

The two major subclasses of HDL contain apo A-I only (Lp A-I) or both apo A-I and apo A-II (Lp A-I/A-II). We have carried out experiments to quantify the participation of Lp A-I and Lp A-I/A-II in the neutral lipid transfer reaction in normal and hypertriglyceridemic subjects. Thirteen hypertriglyceridemic subjects were studied before and after fenofibrate therapy. Fenofibrate treatment resulted in decreases in total cholesterol, triglycerides (TG), and VLDL cholesterol of 19%, 48%, and 70%, respectively, and a 28% increase in HDL cholesterol, with no significant change in the proportion of Lp A-I and Lp A-I/A-II particles. The abundance of cholesteryl ester transfer protein (CETP) mRNA in peripheral adipose tissue decreased with treatment in four of five patients studied; however, no change occurred in plasma CETP mass. Using an isotopic transfer assay, we demonstrated that both Lp A-I and Lp A-I/A-II participated in the CE transfer reaction, with no change after fenofibrate therapy. This finding suggests that the marked increase in HDL cholesterol during fenofibrate therapy is due to normalization of plasma TG and hence decreased opportunity for mass transfer of lipid between HDL and TG-rich proteins in vivo. In this population of hypertriglyceridemic subjects, CETP was distributed in both the Lp A-I and Lp A-I/A-II subfractions of HDL, with preferential association with the smaller Lp A-I poor. In contrast, in nine normal subjects studied, negligible amounts of CETP were associated with Lp A-I/A-II. Nonetheless, the Lp A-I/A-II fraction of HDL contributed significantly to total CE mass transfer in normolipidemic plasma. Lp A-I/A-II is an efficient donor for CE transfer to TG-rich lipoproteins, and its low affinity for CETP may in fact facilitate neutral lipid transfer either by a shuttle mechanism or by formation of a ternary complex.

ABSTRACT

This is a report on two cases of mesomelic dysplasia Langer type. This is a rare kind of dwarfism which combines severe dwarfism with predominant shortening of the forearms and lower legs and other morphological abnormalities. The diagnosis can be made by ultrasonography in the early second trimester of the pregnancy.

ABSTRACT

A previous study detailed the morphometric characteristics of living in-vitro fertilized human pronuclear zygotes and cleaved embryos. A comparison of the different embryo cell stages confirmed the asynchronous division process during early embryo development. Global results showed no evidence of morphometrical differences between embryo subpopulations according to their classical microscopical grading. In this report, further information on illumination of human embryos and analysis of image processing is given. Some examples of embryo images belonging to a normal asynchronous division process are shown. A new parameter was retrospectively attributed to each cleaved embryo based on whether or not they were considered to have undergone asynchronous division that qualified as normal. A non-parametric analysis of this preliminary sample showed that this qualifier was correlated with implantation and acted complementarily with embryo grading. In conclusion, the asynchronous division process qualified as normal and its deviations seem to be a new parameter to take into account during embryo scoring.

ABSTRACT

A total of 304 human pronuclear zygotes and cleaved embryos from the 2- to 9-cell stages, obtained during invitro fertilization attempts, were photographed and retrospectively analysed after transfer for their morphology and size in relation to their developmental stage, using the Imagenia programme of a Biocom 500 image analyser. Morphometric parameters were calculated from the perimeters, surface measurements, theoretical diameters and circularity factors for the different structures analysed. This report provides the morphometric characteristics of living embryos. For the whole population the mean values were: 157.4 microns for the external zona pellucida diameter, 121.8 microns for the internal zona pellucida diameter, 17.9 microns for the thickness of the zona pellucida and 117.2 microns for the embryo cell mass diameter. The morphometric characteristics of the pronuclear-stage population were significantly different from the cleaved cell stages. If the zona pellucida and cell mass embryo diameters increased slowly from the 2- to 9-cell stages, embryonic external diameters were higher and zona pellucida thicknesses were lower in odd than even number blastomere embryos. Preliminary results show that in cases where implantation occurs, the embryo has a lower zona pellucida thickness. A comparison of the different embryo cell stages confirmed the existence of an asynchronous division process during early embryo development. Global results show no evidence of morphometric differences between subpopulations of the embryos according to their microscopic grading. Deviations from the normal asynchronous division process, however, appear to be a new parameter to take into account during embryo scoring.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

PIP: Some cases of infertility considered inexplicable have been found to have an immunologic basis. Spermatozoa are highly antigenic cells. When the state of immune tolerance is disrupted, auto-immunization in the man or isoimmunization in the woman can occur. The appearance of antibodies directed against the sperm antigens results in a condition of hypofertility more than of absolute sterility. Numerous antigens have been identified on sperm using monoclonal antibodies. Immunosuppressive substances have been isolated in the seminal liquid in vitro, and various other protective mechanisms have been identified. Autoimmunity apparently results from failure of the protective processes. Physical, chemical, or infectious trauma may explain the entry of immunocompetent cells. The most commonly used techniques for study of antisperm antibodies are those that detect antibodies directed against surface antigens. Sperm agglutination tests have been criticized for their numerous false positive findings and their failure to identify the classes of immunoglobulins implicated. Tests of immobilization or cytotoxicity are specific, with no false positives, but not sensitive, giving rise to false negatives. The Mixed Antiglobulin Reaction Test (MAR- test) is very specific, easy, inexpensive, and rapid, but it only detects IgG and determination of the place of fixation is difficult. The immunobead test proposed in 1982 overcame some of the limitations of the MAR-test. These two are the methods of choice in exploration of male autoimmunity. Radioimmunologic techniques, an ELISA-type test, and others have given less satisfactory results. The frequency of antisperm antibodies has been estimated at 3 to 15% in nonselected infertile men, 35% among men with some symptoms or a history of the condition, and less than 1% among fertile men. The antisperm antibodies have functional significance only when they are fixed to their antigens. Modifications of sperm mobility are the main problem, with blockage of transport to the oocyte and union with it. It is difficult to establish a prognosis because evaluation must be done individually. As the level of antibodies increases, the chances of spontaneous pregnancy decline. Several treatments have been developed but results have been disappointing. In vitro fertilization after separation of motile sperm without antibodies may improve the prospects of pregnancy.^ieng

ABSTRACT

Ninety-five percent of the neonatal cases of bowel atresia result from jéjuno-ileal obstructions. Frequency is estimated from 1/3,000 to 1/5,000. We observed a case of small bowel volvulus secondary to jejunal atresia diagnosed at 35 weeks gestation. The ultrasound examination was performed due to decreased perception of active fetal movements. Fetal extraction was successful before perforation and meconial peritonitis.

ABSTRACT

UNLABELLED: Thirty-nine women, aged 20 to 40 years, suffering from endometriosis, were treated in three different ways before fertilization in vitro (FIV). Excluded from the trial were all cases of Seventy five stimulated cycles were carried out altogether for the purposes of FIV. The results of the three methods of treatment, in terms of number of pregnancies, obtained after FIV, are compared. RESULTS: First method: surgical treatment. It was applied to 4 patients, suffering from severe endometriosis. The FIV (6 stimulations) give rise only to one pregnancy, interrupted through spontaneous abortion, during the second month. Second method: therapeutic treatment. Applied to 17 patients (mild-7, moderate-7, and severe cases-3). The FIV (32 stimulations) brought 4 pregnancies, run normally to the term, and 2 pregnancies, interrupted through spontaneous abortions. Third method: combined (therapeutic surgical) treatment, applied to 18 patients (mild-3, moderate-9, and severe cases-6). In this group the FIV (37 stimulations) give best results: 9 pregnancies terminated successfully. Three false pregnancies were found (biochemically). No abortion. The possibilities and the restrictions of each method of treatment are discussed. These results are considered as an indication that combined (therapeutic-surgical) treatment is the most appropriate with a view to a successful following FIV.

ABSTRACT

For this study, we selected 41 adult patients with the classic clinical diagnosis of heterozygous familial hypercholesterolemia (FH), which is characterized by a low-density lipoprotein (LDL) cholesterol level above the 95th percentile, xanthomas, and/or personal or familial cardiovascular history. We used an indirect immunocytofluorimetric assay to classify these 41 subjects according to LDL receptor function on lymphocytes. We found that LDL receptor activity was normal in nine patients. A large study of plasma lipid, lipoprotein, and apolipoprotein levels found no significant difference between patients with and without LDL receptor defect. Familial defective apolipoprotein (apo) B-100 (FDB) and LDL-binding defects were not found in the nine patients without LDL receptor defect. These results suggest that other defects in the regulation of lipoprotein metabolism are capable of giving rise to a clinical and biochemical disorder indistinguishable from classic FH.
