Abstract
The nutritional value, heavy metal content and lipid quality of five marine fishes from, Cameroon coast were be investigated. Fish samples from Ilisha africana, Sardinella, maderensis, Cyprinus carpio, Arius parkii and Ethmalosa fimbriata were collected at, the Douala sea port, carried to the laboratory, washed with distilled water and, processed. Proximal composition, minerals, lipid quality and heavy metal analyses, were performed using AOAC standard methods. Results show that proteins (18.43%), and lipids (3.69%) contents were higher in Ilisha africana. Cyprinus carpio had the, highest ash content (4.59%). Contents of minerals and heavy metals were found as, follows: P > Mg > K > Ca > Na > Fe > Zn > Cu > Mn and Hg > Pb > Cd > As. Oils extracted from C. carpio, A. parkii and E. fimbriata were semi-siccative while those of I. africana and S. maderensis were siccative. Thus, these fish species are good sources of proteins and, minerals that can be used for managing mineral deficiencies in humans and animals.

Abstract
OBJECTIVES Caloric restriction (CR) has been shown to slow the aging processes in a number of preclinical studies and reduces expression of aging-associated biomarkers in human trials. We hypothesized that CR would lead to increased incidence of ketosis and that ketosis in CR individuals would alter the aging-protective effects of CR or biomarkers thereof. DESIGN/SETTING/PARTICIPANTS We analyzed data from the "Comprehensive Assessment of Long-Term Effects of Reducing Intake of Energy (CALERIE, Phase 2)" Public Use Database available at calerie.duke.edu. In this study, non-obese adults between the ages of 21 and 50 were randomized to 25% CR or control (ad lib) diet groups and extensively monitored for two years. Given our focus on the effect of caloric restriction on ketosis, individuals with detectible ketones during the baseline visit (pre-randomization) and those with missing data for ketone testing were excluded from the analysis, leaving 71 control and 117 CR participants. MEASUREMENTS We analyzed the incidence of ketosis as well as ketosis free survival in control and CR participants and assessed the effect of ketosis on a number of clinical lab values, functional assessments, and participant survey data related to aging biology. RESULTS We report that CR was associated with modestly increased incidence of ketosis (4.4% in CR vs 1.9% in control), though CR-associated changes in T3, VO2, SUMPT-WT (weight normalized composite strength score - peak torque), physical functioning, and general health did not appear to be altered by the presence or absence of ketosis. Additional observations of interest include: 1) striking patterns of biomarker expression changes (MCP-1, TNFα, TGF-β1, GH) in both the control and CR participants between the baseline visit and the 24-month post-randomization visit and 2) pro-growth/anti-inflammatory baseline (pre-randomization) biomarker expression profile in CR individuals that later test ketone positive relative to other CR individuals. CONCLUSIONS CR modestly increases the incidence of ketosis in healthy adults, yet the increase in ketosis in CR patients did not significantly affect the aging-protective effects of CR. However, given the relatively small number of participants who were ketone positive, further investigation in larger study cohorts is still required for definitive conclusions.

Abstract
Background Pigs/bovines share with humans some of the antigens present on cardiac valves. Two such antigens are: the major xenogenic Ag, “Gal” present in all pig/bovine very close to human B-antigen of ABO-blood-group system; the minor Ag, pig histo-blood-group AH-antigen identical to human AH-antigen and present by some animals. We hypothesize that these antigens may modify the immunogenicity of the bioprosthesis and also its longevity. ABO distribution may vary between patients with low (<6 years) and high (≥15 years) bioprostheses longevity. Methods Single-centre registry study (Paris, France) including all degenerative porcine bioprostheses (mostly Carpentier-Edwards 2nd/3rd generation heart valves) explanted between 1985 and 1998 and some bovine bioprostheses. For period 1998–2014, all porcine bioprostheses with longevity ≥13 years (follow-up ≥29 years). Important predictive factors for bioprosthesis longevity: number, site of implantation, age were collected. Blood group and other variables were entered into an ordinal logistic regression analysis model predicting valve longevity, categorized as low (<6 years), medium (6–14.9 years), and high (≥15 years). Findings Longevity and ABO-blood group were obtained for 483 explanted porcine bioprostheses. Mean longevity was 10.2 ± 3.9 years [0–28] and significantly higher for A-patients than others (P = 0.009). Using multivariate analysis, group A was a strong predictive factor of longevity (OR 2.09; P < 0.001). For the 64 explanted bovine bioprosthesis with low/medium longevity, the association, with A-group was even more significant. Interpretation Patients of A-group but not B have a higher longevity of their bioprostheses. Future graft-host phenotyping and matching may give rise to a new generation of long-lasting bioprosthesis for implantation in humans, especially for the younger population. Fund None.

Abstract
Laryngeal schwannoma is a rare benign tumour of the larynx. Schwannomas derive from the Schwann cells. The majority occurs in supraglottic area and may arise at any age. Magnetic resonance imaging (MRI) is the best imaging tool for suggesting the diagnosis in the appropriate clinical context. Conservative surgery is the treatment of choice. These tumors have to be distinguished from neurofibromas. We report 2 cases of laryngeal schwannoma. The first one concerned an 8-month-old baby with a laryngeal stridor history which seemed to be related to laryngomalacia. The second case was a 22-year-old man with a 5-year history of dysphonia. On nasofibroscopic examination, a sub mucosal mass enlarged the posterior part of the right false vocal cord in both cases. Both CT scan and MRI sequences showed a well margined lesion in the same place. Histological biopsies identified a schwannoma. External surgeries were subsequently and successfully performed. Diagnosis (imaging), specific treatment (endoscopic or external surgery), and possible association of laryngeal schwannomas are discussed.

Abstract
Bifidobacteria, naturally present in the dominant colonic microbiota, represent up to 25% of the cultivable faecal bacteria in adults and 80% in infants. As probiotic agents, bifidobacteria have been studied for their efficacy in the prevention and treatment of a broad spectrum of animal and/or human gastrointestinal disorders, such as colonic transit disorders, intestinal infections, and colonic adenomas and cancer. The aim of this review is to focus on the gastrointestinal effects of bifidobacteria as probiotic agents in animal models and man. The traditional use of bifidobacteria in fermented dairy products and the GRAS ('Generally Recognised As Safe') status of certain strains attest to their safety. Some strains, especially Bifidobacterium animalis strain DN-173 010 which has long been used in fermented dairy products, show high gastrointestinal survival capacity and exhibit probiotic properties in the colon. Bifidobacteria are able to prevent or alleviate infectious diarrhoea through their effects on the immune system and resistance to colonization by pathogens. There is some experimental evidence that certain bifidobacteria may actually protect the host from carcinogenic activity of intestinal flora. Bifidobacteria may exert protective intestinal actions through various mechanisms, and represent promising advances in the fields of prophylaxis and therapy.

Abstract
Ethmoid adenocarcinoma is a rare tumour of the ethmoidal sinuses. The authors report on the clinical features, treatment and follow-up results in 19 cases. Risk factors were those regularly encountered. Delay to diagnosis was long due to the nonspecific clinical features and course. Nasal endoscopy was essential for follow-up. Computed tomography and magnetic resonance imaging were also required to assess tumour spread. Our results suggest that radiotherapy following surgery should be preferred. Survival rate is generally low for this type of tumor. We had 77% survival at 5 years.

Abstract
PURPOSE To investigate the long-term effects of X-irradiation on different aspects of gastrointestinal function in the non-human primate (Macaca mulatta). MATERIALS AND METHODS Animals were exposed to X-radiation (5 or 6 Gy) or not (sham) and gastrointestinal function was investigated 4-6 years after exposure. Basal and agonist-stimulated short circuit current (Isc) responses were measured in isolated jejunum. Intestinal tissue was taken for histological analysis as well as for determination of mucosal marker enzyme activities and gastrointestinal regulatory peptide levels. Vasoactive intestinal peptide receptor characteristics were determined as well as VIP-stimulated Isc responses. GI peptides were also measured in plasma. RESULTS Few differences were seen in basal electrical parameters or tissue morphology but there was a tendency for reduced basolateral membrane enzyme activity. VIP-stimulated Isc responses were reduced in irradiated animals as were VIP-stimulated adenylate cyclase responses. Plasma and tissue (ileal and colonic muscle layers) gastrin releasing peptide levels were increased in irradiated animals. In contrast circulating gastrin levels were lower. CONCLUSIONS Late effects of total-body irradiation on GI function in monkeys showed altered circulating and tissue levels of some GI peptides. In addition the biological effects of vasoactive intestinal peptide were modified.

Abstract
The aim of this study was to determine whether ionizing radiation modifies muscarinic regulation of intestinal mucosal function. Rats exposed to total body 8-Gy gamma-irradiation or sham irradiated were studied up to 21 days after irradiation. Basal and carbachol-stimulated short-circuit current (Isc) and transepithelial conductance (Gt) of stripped ileum were determined in Ussing chambers. Muscarinic receptor characteristics using the muscarinic antagonist [3H]quinuclidinyl benzilate and three unlabeled antagonists were measured in small intestinal plasma membranes together with two marker enzyme activities (sucrase, Na+-K+-ATPase). Enzyme activities were decreased 4 days after irradiation (day 4). Basal electrical parameters were unchanged. Maximal carbachol-induced changes in Isc and Gt were increased at day 4 (maximal DeltaIsc = 195.8 +/- 14.7 microA/cm2, n = 19, vs. 115.4 +/- 8.2 microA/cm2, n = 63, for control rats) and unchanged at day 7. Dissociation constant was decreased at day 4 (0.73 +/- 0.29 nM, n = 10, vs. 2.14 +/- 0.39 nM, n = 13, for control rats) but unchanged at day 7, without change in binding site number. Thus total body irradiation induces a temporary stimulation of cholinergic regulation of mucosal intestinal function that may result in radiation-induced diarrhea.

Abstract
We report one case of a cervical pseudo-tumoral form of histiocytic necrotizing lymphadenitis (Kikuchi Fugimoto disease) occurring in a 13-year-old child. Diagnosis was made only by histology examination of an excision biopsy from one cervical lymph node. Spontaneous complete resolution occurred within 2 months. A review of the clinical and histological features in adults and children is presented. No difference was found between the two populations regarding these features. Differential diagnoses are malignant lymphoma, systematic lupus erythematosus and, in particular, Still's disease in children. The etiology of the disease is also discussed.

Abstract
We report an unusual case of spheno-ethmoidal rhinoscleroma. This chronic granulomatous disease occurs sporadically in Western Europe. Culture is necessary for diagnosis showing the causative organism of rhinoscleroma, Klebsiella rhinoscleromatis. Immunocytochemistry is used in any suspicious case with a negative culture. Antibiotics are the mainstay of therapy for several weeks, using ciprofloxacine or rifampicin, until the nasal biopsies demonstrated no Klebsiella organism.

Abstract
Visual event-related brain potentials (ERPs) were recorded during a running memory task, in which subjects dynamically revised (updated) memory stores, and a control task not requiring maintenance of a changing memory set but utilising identical stimulus sequences and response patterns. In three experiments, ERPs associated with cognitive processes were isolated through subtraction of control potentials from ERPs acquired during updating. We provide evidence that resultant difference ERPs primarily reflected processing or processing control, as opposed to storage. These findings are consistent both with Baddeley's working memory model, which postulates separate storage and control modules, and Morris and Jones' behavioral evidence for specific involvement of Baddeley's central executive in memory updating. In addition, our ERP data indicate that updating requires processes not suggested by Morris and Jones' behavioural studies; possibly control processes engaged to reduce the effects of proactive interference. Overall the data are consistent with the discovery of an ERP correlate of central executive activity.

Abstract
The human enterocytic cell lines Caco-2, HT29, HCT8 and the Caco-2 clones TC7 and PF11 were studied for their ability to support Cryptosporidium parvum development. Following the addition in cultures of either oocysts or excysted sporozoites, immunofluorescent and transmission electron microscopy revealed the presence of all stages of the parasite life cycle by both procedures, and no difference in the ratio of infected cells was found among cell lines. More oocysts were seen in cell monolayers infected with oocysts than with sporozoites (p < 0.0001). The number of meronts observed was the same after either oocysts or sporozoites inoculation. Data suggest that the two methods yield a same cell infection rate.

Abstract
A chemically defined medium for the growth of Leuconostoc mesenteroides was developed. This medium contained lactose, Mn(sup2+), Mg(sup2+), 12 amino acids, eight vitamins, adenine, uracil, and Tween 80. We showed the beneficial effect of aerobic conditions on growth and that potassium phosphate (135 mM) is a suitable buffer. The growth rate in this medium was 0.85 (plusmn) 0.10 h(sup-1) for the six strains examined, and cell densities up to 3.5 x 10(sup9) CFU/ml were attained.

Abstract
OBJECTIVE To compare the hospital course and clinical outcome of preterm infants with respiratory distress syndrome treated with surfactant and managed with high-frequency oscillatory ventilation (HFOV) or conventional mechanical ventilation (CV) as their primary mode of ventilator support. DESIGN A prospective randomized clinical trial. SETTING Three community-based level III neonatal intensive care units. SUBJECTS A total of 125 neonates who were 35 weeks or less estimated gestation requiring intubation and assisted ventilation for respiratory distress syndrome with arterial to alveolar oxygen ratio less than .50. INTERVENTIONS Patients were randomized to continue CV (61 patients) or be changed to HFOV (64 patients) after exogenous surfactant administration (100 mg/kg). HFOV was used in a strategy to promote lung recruitment and maintain lung volume. Protocol respiratory care guidelines were followed; otherwise routine care was provided by each neonatal intensive care unit. MEASUREMENTS AND MAIN RESULTS No differences were noted in demographic features between the two study groups. The study population birth weight was 1.51 +/- .47 kg (mean +/- SD), gestational age was 30.9 +/- 2.5 weeks, and study entry age was 2 to 3 hours. Patients randomized to HFOV demonstrated the following significant findings compared with CV-treated patients: vasopressor support was less intensive; surfactant redosing was not as frequent; oxygenation improved more rapidly and remained higher during the first 7 days; fewer infants required prolonged supplemental oxygen or ventilator support; treatment failure was reduced; more patients survived without chronic lung disease at 30 days; need for continuous supplemental oxygen at discharge was less; frequency of necrotizing enterocolitis illness was lower; there were fewer abnormal hearing tests; and hospital costs were decreased. No differences were seen between the two study groups in the frequency or severity of patent ductus arteriosus, air leak, retinopathy of prematurity, or intraventricular hemorrhage. Length of hospital stay and survival to discharge were similar for HFOV- and CV-treated infants. CONCLUSIONS When used early with a lung recruitment strategy, HFOV after surfactant replacement resulted in clinical outcomes consistent with a reduction in both acute and chronic lung injury. Benefit was evident for preterm infants both less than or equal to 1 kg and more than 1 kg. In addition, early HFOV treatment may have had a more global effect on patient health throughout the hospitalization, resulting in reduced morbidity and decreased health care cost.

Abstract
Juvenile chronic arthritis (JCA) was diagnosed in 2 young girls. In one of them, antinuclear antibodies (ANA) were strongly positive during the course of erosive polyarthritis. After 5 years followup, severe renal insufficiency occurred. Antineutrophil cytoplasmic antibodies (ANCA) were positive with a perinuclear pattern on indirect immunofluorescence (IIF) and antimyeloperoxidase (MPO) specificity. Renal biopsy showed severe crescentic glomerulonephritis without significant deposits on IIF. Treatment consisted of prednisone and monthly intravenous cyclophosphamide pulse. Renal failure worsened and hemodialysis was necessary. A 2nd patient was referred for polyarthritis with positive rheumatoid factors without positive ANA. The presence of microscopic hematuria led to the discovery of crescentic glomerulonephritis with positive ANCA of anti-MPO specificity. At latest examination, after prednisone for 10 months and azathioprine for 6 months, the patient had moderate proteinuria with normal renal function. These observations emphasize that in juvenile onset chronic polyarthritis, renal microscopic angiitis with ANCA of anti-MPO specificity may occur.

Abstract
One case of breast neuroendocrine primary small cell carcinoma with light microscopic and immunohistochemical findings is reported. The patient died of unrelated disease 21 months after diagnosis and treatment by modified radical mastectomy, radiotherapy and subsequent chemotherapy. Immunohistochemical studies revealed cytokeratin and neuroendocrine markers (chromogranin, neuron-specific enolase) immunostaining on tumoral cells. Expression for neuropeptides (met-enkephalin, leu-enkephalin, beta-endorphin) and CALLA antigen was found. Based on this case report and six other previously reported cases, breast neuroendocrine primary small cell carcinoma appears to be a very aggressive tumor for which no firm conclusions regarding treatment can be drawn.

Abstract
The effect of microcystin-LR, an inhibitor of protein phosphatases PP1 and PP2A, was studied on protein synthesis by measuring the incorporation of labelled amino acid into protein in isolated rat hepatocytes. Microcystin-LR inhibited protein synthesis in the first minutes of the incubation period, and half-maximum effect was obtained at about 60 nM. Such an inhibition was also observed in the presence of different protein phosphatase inhibitors, i.e. okadaic acid, calyculin A and microcystin-RR. This effect was observed in whole hepatocytes, in the supernatant of the post-mitochondrial fraction and in the microsomal fraction. It was independent of a substrate supply and of the labelled amino acid used. Furthermore, this inhibition preceded the previously reported glucose-6-phosphatase activation induced by microcystin-LR [Claeyssens, Chédeville and Lavoinne (1993) FEBS Lett. 315, 7-10].

Abstract
It is well known that the heart releases a factor called ANF (atrial natriuretic factor) or ANP (atrial natriuretic peptide) capable of inducing rapid diuretic and natriuretic actions. This factor is stored in secretory granules mainly located in myocytes in both atria. The main secretory stimulus is the distention of the atrial cavity resulting, for example, from enhanced venous return. However, the cellular events which occur after the stimulation remain to be clarified. The aim of this investigation was to study the intra-cellular events preceding the ANF release, using the rat hindlimb suspension as model of stimulation. In this model, Wistar rats were placed in a 30 degrees anti-orthostatic position and a blood shift towards the heart was obtained. Different durations (1/4 h, 1/2 h, 3/4 h, 1 h, 2 h and 6 h) were studied. The ANF plasma level was investigated by Radio Immuno Assay and granule immunoreactivity was measured by counting gold particles on micrographs. The ANF plasma level was significantly increased (+60%) after 1 h of suspension. The response was transient and then decreased to basal values. Morphological criteria established at the beginning of this study, and measured throughout the experiment, were found transiently modified after suspension. The surface of the perinuclear area was transitory enlarged by 36% 30 min after suspension. Moreover, in the same time immunoreactivity of the secretory granules was enhanced without changes in granule size. These results suggest an increase in the ANF synthesis and storage in the granules during the stimulation. However, the cellular regulatory mechanism of the ANF synthesis which could explain the transitory aspect of these events, requires further investigation.

Abstract
Renal transplantation in patients presenting end-stage renal failure can be hampered by the presence of alloantibodies against HLA antigens. In 4 out of 5 patients with HLA-specific alloantibodies waiting for a renal allograft, treatment with high-dose i.v. Ig resulted in a prolonged suppression (over 3 months) of most of the panel-reactive anti-HLA antibodies (PRA). Intravenous polyclonal human Ig (IVIg) and F(ab')2 fragments from IVIg inhibited the binding of patients' plasma and IgG fractions to peripheral blood lymphocytes from normal donors as well as their cytotoxicity, suggesting that the in vivo effect of IVIg was mediated by the presence, in the IVIg preparation, of anti-idiotypes directed against idiotypes borne on the anti-HLA antibodies. Thus, treatment with IVIg can be a valuable tool toward the transplantation of immunized patients.

Abstract
We retrospectively analyzed clinical presentation, immunopathological data and renal outcome in 13 patients with glomerulonephritis (GN) and chronic lymphocytic leukemia (CLL) or related diffuse well-differentiated lymphocytic lymphoma (WDLL) of B-cell lineage. B-cell proliferation and glomerulopathy were simultaneously diagnosed in seven of the 13 patients. Nephrotic syndrome was observed in nine patients. Serum creatinine was elevated (greater than 120 mumol/liter) in 10 patients and exceeded 400 mumol/liter in three patients. A clear cut relationship between GN and hematologic disease could be established in nine cases: five patients had MPGN caused by type I or type II cryoglobulinemia; two had MPGN or mesangial hypertrophy with circulating and deposited noncryoprecipitating monoclonal IgG K and IgM K, respectively; in the two remaining patients, monotypic IgG K glomerular deposits exhibiting fibrillary organization were observed in association with MGN or MPGN, despite the absence of circulating M-component by immunofixation. The pathophysiologic link between glomerular lesions and B-cell proliferation was further evidenced by effectiveness of specific treatment of the malignancy by chlorambucil. This drug, used in the absence of steroids, induced complete remission of nephrotic syndrome in the five patients to whom it was given. Moreover, in the five patients with creatininemia greater than 200 mumol/liter who received chemotherapy, substantial improvement in renal function was observed. These overall data demonstrate that the occurrence of GN in B-CLL and related lymphoma is not fortuitous, and testify to the paraneoplastic nature of glomerular involvement mediated by deposition and possibly processing of cryoprecipitating or noncryoprecipitating M-components.

Abstract
Out of our series of 24 children seropositive for the Human Immunodeficiency Virus (HIV), parotid gland enlargement was noted in 4 children with AIDS-related complex (ARC) presenting also a Lymphocytic Interstitial Pneumonitis (LIP) on their chest radiographs. The ultrasound (US) aspect of the parotid gland suggests acinar enlargement (suggesting the presence of lymphocytic infiltration). The aspect displayed in the parotid mirrors the process developing in other areas (lungs, liver, spleen, lymph-nodes), i.e. a syndrome of lymphocytic (CD8) proliferation present at the stage of ARC.

Abstract
High-resolution 1H surface coil NMR spectroscopy (MRS) was used to evaluate in vivo the cerebral metabolism changes in rat brain induced by a glial tumor growing in situ. Tumor cells (C6 glioma cells) were stereotaxically placed in the right hemisphere superficially. 1H MRS was performed using 5-mm surface coils implanted over the right hemisphere and the water was suppressed using a binomial sequence. As the intracerebral tumor size increased, there was a marked decrease in the N-acetyl aspartate level and an increase in the 1.3 ppm peak. Edition of this peak showed that lactate increased but lipids increased much more than lactate. Moreover the ratio between the choline-phosphocholine and creatine-phosphocreatine peaks changed. This study demonstrates that high-resolution surface coil 1H MRS can be used to monitor changes in metabolism associated with growth of an experimentally induced rat brain tumor in situ.

Abstract
A boy, born to a mother with AIDS related complex, was immunised with BCG on the 10th day of life. At the age of 4 months he presented with a local enlarged lymph node, fever, hypotonia, and diarrhoea. Mycobacterium bovis, BCG strain, was grown from the lymph node and cerebrospinal fluid; this proved dissemination.
