Splenic erythropoiesis was demonstrated by surface counting of 59Fe in 129 of 1,350 ferrokinetic studies performed over a 15 year period. These 129 studies were carried out in 108 patients, including 40 with chronic myelogenous leukemia (CML), 24 with agnogenic myeloid metaplasia (AMM), 18 with polycythemia vera (PV), six with a myelodysplastic syndrome, five with acute leukemia, three with prostate or breast carcinoma, two each with aplastic anemia or Hodgkin's disease, and one each with idiopathic thrombocythemia, multiple myeloma, chronic renal failure, or treated hypopituitarism. Splenomegaly was present in 83% of the studies and hepatomegaly in 72%. Grade II-III myelofibrosis was demonstrated in 62% of the cases. Hepatic erythropoiesis was present in 77% of the studies (only 38% in PV), and marrow erythropoiesis was undetectable in 33%. Total erythropoiesis was about twice normal (range 0.2 to 8 times normal) but was ineffective to varying degrees in 86% of the studies. Relationships between organomegaly, myelofibrosis, and extramedullary erythropoiesis, as well as differences among clinical disorders, are discussed. Differences observed between CML in chronic or blastic phase suggested that the erythroid cell line was involved in the proliferative process. It is concluded that splenic erythropoiesis 1) is encountered in a variety of clinical conditions; 2) is not necessarily associated with splenomegaly or myelofibrosis, even in the myeloproliferative disorders; 3) is part of a predominantly extramedullary (in the liver as well as in the spleen), expanded, and largely inefficient total erythropoiesis; and 4) can be evaluated in a semiquantitative manner by surface counting.

After four years of doctoral research on the topic of iron in the roof framing, a detailed typologic timeline could be established. It covers the period between the thirteenth and eighteenth century. The development of such an inventory was possible by the development of an interdisciplinary methodology combining dendrochronology, archaeometallurgy and techniques of building archeology. Reflections and comparisons crossed with nearly 750 armatures from the investigation of 68 roof or attic parts, mainly located in Wallonia, helped to inventory 89 differents frames iron models.

We determined blood plasma testosterone (T) values in bulls from the Friesian (N) and the Belgian White Blue (BBB) breeds, between 1 and 12 months of age. The BBB breed is divided into 2 sub-breeds: one is highly specialized for meat production (BBB-V); the other has mixed zootechnic characteristics (BBB-M). The results obtained show that T values in PN are significantly higher than in BBB-V, for at least, the first 5 months of life. In a second experiment, we followed T profiles for 12 or 24 hours in PN, BBB-M and BBB-V bulls. Every 20 minutes, blood was withdrawn from the jugular vein through a catheter, in order to minimized stress. Data observes are as follows: (1) Luteinizing hormone (LH) plasma levels are comparable in all animals at 130 and 180 days. From then on, average LH values slightly decreased in BBB-V whilst they increase in PN. As early as 130 days, LH secretion shows successive pulses in BBB-V, a similar pulsatile profile appearing later on in PN. (2) Average T values are significantly higher in PN and BBB-M than in BBB-V. T profiles are flat but of increasing average level up to 140 days in PN and 170 days in BBB-V. Thereafter, pulses develop. (3) 24 hour profiles show no influence of daylight upon LH or T parameters. (4) T peaks follow LH peaks by a delay of 60 to 100 minutes. (5) Frequency and amplitude of LH and T peaks differ, on the same day, among two monozygous twins. A third experiment showed that LH and T profiles were similar in two adult BBB-V bulls with significantly different fertility grades. We hypothesize that the delay of sexual maturing frequently observed in sub-breeds highly selected for meat production (BBB-V, for exemple) is related to the delay shown by animals of these breeds to develop T pulsatile profiles with peaks of adequate frequency and amplitude.

Fertility in first-generation hybrids of roach, Rutilus rutilus, and silver bream, Blicca bjoerkna, was investigated. Sperm and egg production of hybrids at first sexual maturity were examined. Eggs from female hybrids were artificially fertilized with the sperm of a corresponding hybrid male; a hybrid male from the reciprocal crossbreeding; a parental species male R. rutilus; and a parental species male B. bjoerkna. The results revealed that gametogenesis was normal in female hybrids. However, in male hybrids, a low efficiency of gametogenesis was observed. The semen of male hybrids was extremely dilute, with spermatozoa concentration lower than that in parental species. Nevertheless, these F1 hybrids (males and females) from reciprocal crossbreeding were fertile. F2 and backcross generations were produced, but F2 crosses from the female hybrid and corresponding hybrid male displayed a drastically slower hatching rate. Also higher proportions of deformed embryos were hatched than in other post-F1-generation crosses. [less ▲]

The eradication of poverty and hunger is the first of the Millennium Development Goals (MDGs) established by the United ations. One of the Rwanda’s commitments is the fulfillment of this goal as indicated in its own long term Vision 2020 aimed at enabling Rwandans to emerge from under-development and poverty status by achieving economic growth objectives in combination with social indicators objectives. As it has been researched that the major cause of poverty in developing countries is the high rate of their population growth, this paper is aimed at assessing the fertility preferences and the level of family planning in Rwanda as a tool to poverty eradication. The paper also presents some challenges and some other pathways to improve the socioeconomic welfare of Rwandan population. In this paper descriptive methods have been used to present and analyze data and a Pearson Chi square test has been used to study the association between variables. The results shows that the knowledge of contraception is universal (99%) but the use of contraception methods for family planning is still very low (37%). On the average fertility preferences are 3.2 children which are good if realized. The general conclusion that emerges from the study is that in order to reduce poverty, family planning is a must but lot more are to be done. Among other things, a focus on increasing rural income and agriculture output. [less ▲]

As a result of the trend toward late childbearing, fertility preser- vation has become a major issue in young women with gynaeco- logical cancer. Fertility-sparing treatments have been successfully attempted in selected cases of cervical, endometrial and ovarian cancer, and gynaecologists should be familiar with fertility- preserving options in women with gynaecological malignancies. Options to preserve fertility include shielding to reduce radiation damage, fertility preservation when undergoing cytotoxic treat- ments, cryopreservation, assisted reproduction techniques, and fertility-sparing surgical procedures. Radical vaginal trachelectomy with laparoscopic lymphadenectomy is an oncologically safe, fertility-preserving procedure. It has been accepted worldwide as a surgical treatment of small early stage cervical cancers. Selected cases of early stage ovarian cancer can be treated by unilateral salpingo-ophorectomy and surgical staging. Hysteroscopic resec- tion and progesterone treatment are used in young women who have endometrial cancer to maintain fertility and avoid surgical menopause. Appropriate patient selection, and careful oncologic, psychologic, reproductive and obstetric counselling, is mandatory. [less ▲]

Management of livestock grazing in highly-productive mountain meadows is an important aspect for the economic viability and the environmental impact of a grassland-based farm. The main aim of this study was to build near infrared models to determine the chemical composition and in vitro organic matter digestibility of Romanian meadow forages. The treatments were organic and mineral fertilizer combinations, and forage samples were obtained from three fertilization experiments conducted in the Apuseni Mountains; these samples were analysed using classical and NIR methods. The samples were scanned in the NIR wavelength band. The CRA-W Gembloux ‘local’ calibration models were validated with Romanian meadow forages and then used in order to predict the forage quality of samples. A second objective of the study was to determine the effects of fertilization on forage quality. The results showed a decrease in crude protein content from the NPK treatment (150:75:75), which can be explained by a reduction of Fabaceae plants with this treatment from 17.25% of the populations in the control (semi-natural meadow not fertilized) to 6.25% in the fertilized plots. The decrease in protein content and in vitro organic matter digestibility was related to a reduced Fabaceae presence. Our recommendation is to use mineral fertilization with NPK doses less than 100:50:50 to improve meadow productivity; meanwhile organic fertilization can also be used to complement and maintain biodiversity and forage quality.
