A qualitative systematic review of coasting, a procedure to avoid ovarian hyperstimulation syndrome in IVF patients.

'Coasting', a method which consists of stopping exogenous gonadotrophins and postponing HCG administration until the patient's serum estradiol (E2) level decreases, is often used to prevent ovarian hyperstimulation syndrome (OHSS). We conducted a systematic review to analyse whether there is sufficient evidence to justify the general acceptance of coasting. The studies, which involved 493 patients in 12 studies, are very heterogeneous in the characteristics and number of patients in the ovulation stimulation schemes.

Galectin-8 expression decreases in cancer compared with normal and dysplastic human colon tissue and acts significantly on human colon cancer cell migration as a suppressor.

Background And Aims: Galectins are beta-galactoside binding proteins. This ability may have a bearing on cell adhesion and migration/proliferation in human colon cancer cells. In addition to galectins-1 and -3 studied to date, other members of this family not investigated in detail may contribute to modulation of tumour cell features.

Textiloma of the thigh presenting as a sarcoma.

Textiloma is defined as a tumor composed of cotton matrix surrounded by granulomatous reaction. It occurs following operations in which surgical sponges were inadvertently left behind. We describe a case of a 59-year-old man presenting with a pathologic fracture of the proximal left femur.

Preventive attitude of physicians to avoid OHSS in IVF patients.

The ovarian hyperstimulation syndrome (OHSS) is a dramatic iatrogenic complication of fertility treatment. There is no consensus about its prevention strategies. We assessed whether physicians modify their preventive attitude in relation to clinical risk factors and to the oestradiol response chart.

Effect of congeneric chemical signals of different ages on foraging response and food choice in the field by golden spiny mice (Acomys russatus).

The common spiny mice Acomys dimidiatus and golden spiny mice Acomys russatus coexist in the extreme warm and dry parts of the Rift Valley in Israel. However, they are temporally segregated in that the former is nocturnal, whereas the latter is diurnal. Daily rhythms of physiological and behavioral variables in A.

A survey of physicians' attitude towards women with postmenopausal bleeding.

Objective: To study how gynaecologist manage postmenopausal bleeding in women not using HRT. The impact on the physicians' attitude of risk factors for endometrial cancer and of the endometrial thickness was essentially accounted for.

Methods: Two different case-types were defined by modifying the risk level of developing endometrial cancer.

Molecular phylogenetic analyses of the mitochondrial ADP-ATP carriers: the Plantae/Fungi/Metazoa trichotomy revisited.

We investigated the basal phylogeny of eukaryotes through analyses of sequences from the ADP-ATP mitochondrial carrier, a transmembrane protein that is stable in function across eukaryote kingdoms. The ADP-ATP data strongly suggest the grouping of Plantae and Fungi to the exclusion of Metazoa. We implemented several procedures to avoid pervasive analytical artifacts such as erroneous alignment, random rooting, long branch attraction, and misidentification of noisy characters.

A one-day prevalence survey of hospital-acquired infections in Lebanon.

A one-day survey was carried out in 14 acute care hospitals in Lebanon in May 1997, to determine the prevalence of nosocomial infection (NI) by site of infection, hospital department, micro-organism and pathology. Hospitals (N=14) with more than 50 beds were selected at random from the official Lebanese Health Ministry Registration Directory. All patients who presented that day on the ward and were not admitted or discharged, were included.

SOAP, cleaning multiple alignments from unstable blocks.

SOAP is a stand-alone, multi-platform program to test the stability of a multiple alignment of molecular sequences.

Effect of physicians opinion on patients' choice of treatment.

Background: While it is obvious that patients should be involved in the decision making process, questions arise as to whether it is feasible to inform them objectively.

Objective: To assess the impact of the physician's opinion, on the choice of treatment, to the patient.

Setting: We imagined a hypothetical case of a 55-years-old woman with a high risk of osteoporosis.

Amphibians as indicators of early tertiary "out-of-India" dispersal of vertebrates.

Sixty-five million years ago, massive volcanism produced on the India-Seychelles landmass the largest continental lava deposit (Deccan Traps) of the past 200 million years. Using a molecular clock-independent approach for inferring dating information from molecular phylogenies, we show that multiple lineages of frogs survived Deccan Traps volcanism after millions of years of isolation on drifting India. The collision between the Indian and Eurasian plates was followed by wide dispersal of several of these lineages.

Feeding specialization and host-derived chemical defense in Chrysomeline leaf beetles did not lead to an evolutionary dead end.

Combination of molecular phylogenetic analyses of Chrysomelina beetles and chemical data of their defensive secretions indicate that two lineages independently developed, from an ancestral autogenous metabolism, an energetically efficient strategy that made the insect tightly dependent on the chemistry of the host plant. However, a lineage (the interrupta group) escaped this subordination through the development of a yet more derived mixed metabolism potentially compatible with a large number of new host-plant associations. Hence, these analyses on leaf beetles document a mechanism that can explain why high levels of specialization do not necessarily lead to "evolutionary dead ends.

Antibodies raised against the flagellar pocket fraction of Trypanosoma brucei preferentially recognize HSP60 in cDNA expression library.

A purified flagellar pocket fraction of the Trypanosoma brucei AnTat 1.1E clone was used for the generation of polyclonal antiserum in rats. Anti-flagellar pocket antibodies present in this serum recognized several proteins distinct from the major variant surface glycoprotein (VSG).

Health perception by women who work in a medical environment.

A mail survey was sent to 1154 women working in a university hospital, to assess the perception of health and the uptake of prevention strategies in an optimal setting. A list of 13 diseases was submitted and the women were asked to list the five diseases they found to be the most important for a woman of their age. Breast cancer was ranked among the five most important diseases by 85% of the women and uterus cancer by 71.

Convergent adaptive radiations in Madagascan and Asian ranid frogs reveal covariation between larval and adult traits.

Recent studies have reported that independent adaptive radiations can lead to identical ecomorphs. Our phylogenetic analyses of nuclear and mitochondrial DNA sequences here indicate that a major radiation of ranid frogs on Madagascar produced morphological, physiological, and developmental characters that are remarkably similar to those that independently evolved on the Indian subcontinent. We demonstrate further that, in several cases, adult and larval stages each evolved sets of characters which are not only convergent between independent lineages, but also allowed both developmental stages to invade the same adaptive zone.

The menopause in Europe.

Most women in developed countries will live a third of their lives after the menopause. Vasomotor symptoms (hot flushes, night sweats, irritability, sleep disturbances, mood swings), and urogenital complications (atrophic vaginal irritation and dryness, dyspareunia) occur frequently during this period of life, but their severity and duration may vary widely between individuals. The menopause also induces accelerated bone loss and is the principal risk factor for osteoporosis.

Effect of the serine protease inhibitor N-tosyl-l-phenylalanine-chloromethyl ketone (TPCK) on MCF-7 mammary tumour cells growth and differentiation.

Previous studies from this and other laboratories indicated that the oestrogen-regulated heat shock protein HSP27 is involved in the control of MCF-7 cells growth and differentiation, as it also appears to be in other cell types, including osteoblasts and HL-60 cells. In the latter instance, induction of differentiation is associated with the downregulation of myeloblastin, a serine protease now identified as proteinase 3 (hence its designation as PR3/Mbn), mirrored by an increase in the cellular content of the small heat shock protein HSP27, a substrate to this enzyme. Besides, antisense inhibition of PR3/Mbn production sufficed for inducing HL-60 cells monocytic differentiation.

The unseen face of humanitarian crisis in eastern Democratic Republic of Congo: was nutritional relief properly targeted?

Study Objective: Comparison of children's nutritional status in refugee populations with that of local host populations, one year after outbreak refugee crisis in the North Kivu region of Democratic Republic of Congo.

Design: Cross sectional surveys.

Setting: Temporary and other settlements, in the town of Goma and surrounding rural areas.

Effect of intrathecal baclofen on gait control in human hereditary spastic paraparesis.

The covariation between thigh, shank and foot elevation angles during locomotion was analysed by means of orthogonal planar regression in a patient with pure hereditary spastic paraparesis before and after an intrathecal bolus of baclofen and in seven healthy subjects. The size, shape and spatial orientation of the loop defining patient's planar covariation (thigh angle vs. shank angle vs.

Comparative analysis of antibody responses against HSP60, invariant surface glycoprotein 70, and variant surface glycoprotein reveals a complex antigen-specific pattern of immunoglobulin isotype switching during infection by Trypanosoma brucei.

During Trypanosoma brucei infections, the response against the variant surface glycoprotein (VSG) of the parasite represents a major interaction between the mammalian host immune system and the parasite surface. Since immune recognition of other parasite derived factors also occurs, we examined the humoral host response against trypanosome heat shock protein 60 (HSP60), a conserved antigen with an autoimmune character. During experimental T.

The 21-aminosteroid U74389G enhances hepatic blood flow and preserves sinusoidal endothelial cell function and structure in endotoxin-shocked dogs.

Background: 21-Aminosteroids are potent anti-inflammatory and antioxidant drugs that provide remarkable endothelial protection in different models of tissue ischemia-reperfusion and inflammation. The effects of 21-aminosteroids in sepsis, a highly inflammatory condition leading to panendothelial activation and injury, are largely uninvestigated. We therefore explored the effects of the 21-aminosteroid U74386G on hepatic blood flow, endothelial cell function, and sinusoidal structure in a canine model of fluid-resuscitated, hyperdynamic endotoxic shock.

Adaptive motor strategy for squatting in spastic diplegia.

Motor strategies, defined by kinetic, kinematic and/or muscle activation patterns, reflect neural planning of movement, which takes into account central as well as peripheral constraints. Major alteration is expected in cerebral palsy, a condition characterized by abnormal posture and movement secondary to early lesion of the brain. The objective of this study was to characterize the motor strategies involved in disruption of posture in cerebral palsy of the spastic diplegia type and compare them with normal controls.

Sporadic case of trichorhinophalangeal syndrome type III in a European patient.

Trichorhinophalangeal syndrome type III (TRP III) shares common traits with TRP I and II, including sparse hair, a "pear-shaped" nose, osteodysplasia with cone-shaped epiphyses, and autosomal dominant inheritance, but is distinguished by the presence of severe brachydactyly. TRP III was first described in 1984 in Japanese patients, one sporadic case [Sugio and Kajii, 1984: Am. J.

Comparison of methods based on annexin-V binding, DNA content or TUNEL for evaluating cell death in HL-60 and adherent MCF-7 cells.

HL-60 and MCF-7 cells were treated with 0.15 microM camptothecin (CPT) or with the solvent dimethylsulfoxide (DMSO) for the controls, for 2, 3 and 4 h or for 24, 48 and 72 h, respectively. The apoptotic index (AI) was then evaluated in parallel by the following flow cytometric methods: (1) double staining of unfixed cells with fluoresceinated annexin V and propidium iodide (PI), this after detachment by trypsinization in the case of MCF-7 cultures; (2) prefixation in 70% ethanol, extraction of degraded, low molecular weight DNA with 0.
