Summary.  Fresh frozen plasma (FFP) is the main source of factor IX (FIX) in the treatment of bleeding episodes of haemophilia B in the Philippines. Cryoprecipitate-removed plasma otherwise known in the Philippines as cryosupernate, is a by-product of cryoprecipitate preparation. These blood products expire in storage or are just thrown- away because of less demand for clinical use. By theory, this product should have almost the same amount of FIX as in FFP, therefore can be used in the treatment of haemophilia B. There is no local data on the actual FIX content of the cryoprecipitate-removed plasma. Hence, the authors established these data to support the use of this product. Eighty-three bags of cryoprecipitate-removed plasma received from three different blood banks in Manila, Philippines were tested for FIX activity using an activated partial thromboplastin time (APTT)-based one-stage FIX assay. The FIX content in each bag of cryoprecipitate-removed plasma was calculated by multiplying its volume in mL with that of FIX activity per mL of plasma measured in vitro. The total mean FIX content per bag was 212.20 U (±88.98) exceeding the contents set by the American Association of Blood Banks (AABB, 70–90 U). The mean FIX activity per bag was 127.62% (±38.23) with the mean volume of 164.28 mL (±52.23). Statistically significant difference on volume (P = 0.000) was found across the three sources resulting to a significant variation of the actual FIX content (P = 0.000).

Abstract For the violent collisions of 27 MeV/nucleon40Ar with Ag, coincidence measurements have been made between heavy residues and intermediate mass fragments (3≦Z≦14) or light charged particles. From the analysis of the correlation between heavy residues (mass and velocity) and intermediate mass fragments, the main characteristics of the dominant mechanisms, fusion and partially damped collisions preceded or accompanied by a preequilibrium emission, are presented. Balances concerning mean values of parallel linear momentum, mass and atomic number, are established and confirm that a complete description of violent collisions was obtained. Then thermalization is discussed, first in terms of excitation energies derived from kinematics between heavy residues and intermediate mass fragments, and secondly in terms of initial temperature estimates derived from light charged particle spectra. Very hot nuclei (T⋍5.7–6.6 MeV) are produced over a large impact parameter range from very central collisions to medium peripheral ones. Various experimental results are compared to predictions obtained with semi-classical calculations (Landau-Vlasov equation). From their good agreement one may conclude that, depending on the impact parameter, thermal equilibrium is achieved within 4–10×10−22 s.

Summary The effect of inorganic phosphate concentrations on antibiotic and extracellular protein production by Myxococcus coralloides D have been examined. Antibiotic production by growing cells of this myxobacterium was maximal at phosphate concentrations of 10–20 mM, but was inhibited by concentrations higher than 20 mM. The total extracellular protein and the extracellular protein per cell ratio were independent of phosphate levels in the culture broth.

Abstract  The climate at the Last Interglacial Maximum (125 000 years before present) is investigated with the atmosphere-ocean general circulation model ECHAM-1/LSG and with the climate system model of intermediate complexity CLIMBER-2. Comparison of the results of the two models reveals broad agreement in most large-scale features, but also some discrepancies. The fast turnaround time of CLIMBER-2 permits one to perform a number of sensitivity experiments to (1) investigate the possible reasons for these differences, in particular the impact of different freshwater fluxes to the ocean, (2) analyze the sensitivity of the results to changes in the definition of the modern reference run concerning CO2 levels (preindustrial versus “present”), and (3) estimate the role of vegetation in the changed climate. Interactive vegetation turns out to be capable of modifying the initial climate signals significantly, leading especially to warmer winters in large parts of the Northern Hemisphere, as indicated by various paleodata. Differences due to changes in the atmospheric CO2 content and due to interactive vegetation are shown to be at least of the same order of magnitude as differences between the two completely different models, demonstrating the importance of careful experimental design.

Summary Estrogens retard bone loss after menopause and constitute the most logical therapy for the prevention of postmenopausal osteoporosis. Estrogens are contraindicated in some circumstances and some postmenopausal women are unwilling to accept them. We have used ADFR therapy as an alternative in the prevention of postmenopausal bone loss. One hundred women in the early postmenopausal period (6–24 months since the last menses) were introduced into the study. 50 were treated with placebo and 50 were treated with ADFR therapy (phosphorus 1.5 gr/day during 3 days, followed by SCT 100 UI/day during 10 days and calcium 1 gr/day). After 77 days without any therapy we repeated the cycles every 3 months. Bone mass was evaluated at the beginning and at 3, 6, 12 and 18 months by dual-photon absorptionmetry lumbar spine. In the control group, the mean spinal BMD decreased 7.31% after 12 months and 6.16% after 18 months (p〉0.05). The ADFR group only had a mean spinal BMD decrease of 3.79% and 1.1% after 12 and 18 months respectively (NS). Bone loss was greater in control than in ADFR group after 12 and 18 months (p〈0.05 at both times). We conclude that phosphorus and calcitonin like ADFR therapy may be a useful alternative to estrogen for the prevention of accelerated bone loss after menopause.

Abstract The structures in the total kinetic energy (TKE) distributions in cold fission of234U and236U are interpreted in terms of the Coulomb interaction energy (C) between fragments at the scission point. The maximal value ofC, C max, corresponding to the most compact scission configuration, is calculated for several mass fragmentations. It is shown that withQ being constant,C max increases if one increases the charge asymmetry for a given primary fragmentation. This condition produces oscillations with a period of approximately 5 amu ofC max as a function of the light fragment mass which are correlated with the observed oscillations of the maximal value of TKE. Moreover, the enhancement of the yields of the more asymmetric charge fragmentation for a given fragmentation is explained.

Abstract For the compound nucleus179Au formed at an excitation energy of 26 MeV in the fusion reaction90Zr+89Y, the energy spectra of promptly emitted protons,α particles andγ rays were measured in concidence with the evaporation residues. On the basis of the measured total decay energy, the 1p and 1α decay channels were separated from all other evaporation-residue channels. The energy spectra and absolute cross sections, together with previously measured excitation functions for various decay channels, are successfully described by statisticalmodel calculations with the Monte Carlo code CODEX.

Abstract The dynamics of the two partners produced in dissipative collisions has been experimentally studied for the system40Ar + Ag at 27 MeV per nucleon. Primary masses of the fragments can then be calculated; the excitation energy partition between the two fragments is derived from the number of particles evaporated by each fragment. We found that this division evolves from equipartition to a repartition close to thermal equilibrium in the excitation energy range 300–350 MeV or interaction times 5-10×l0−22 s.

Abstract The time-of-flight technique was used to measure the mass and kinetic energy distribution of fragments from fission of233U,235U and239Pu, induced by thermal neutrons at the Grenoble High Flux Reactor. The data array is presented as equal probability lines in the high kinetic energy regions. The fluctuations observed in those experimental lines are explained by a static scission configuration model, in which the most important influence comes from the Coulomb interaction energy between the two fragments. The highest values of total kinetic energy are obtained for fragmentations with heavy fragmentsZ=50–52,N=80–82 and light fragmentsZ=40–42,N=60–64.
