Abstract
Amino-Plex (SM1997) is a spray or liquid cosmeceutical that has been used for skin dryness, aging, or sun exposure. Its formulation includes electrolytes, trace minerals, amino acids, peptides, nucleosides and nucleotides, all substances that are <10 kDa. It is designed to increase oxygen levels in cells, improve glucose transport, stimulate ATP synthesis, and stimulate collagen formation, actions that can help facilitate repair of damaged cells. It also supports collagen synthesis and formation of healthy granulation tissue, accelerating reepithelization of damaged skin. Here, SM1997 has been tested as an agent to improve the healing of mustard injury to the cornea. The results indicate that SM1997 facilitates the retention of corneal epithelial attachment when applied to corneal organ cultures after nitrogen mustard exposure. In addition, it reduces the activation of enzymes that lead to epithelial-stromal separation, namely, ADAM17 and MMP-9. Therefore, SM1997 should be further investigated as a potential therapy sulfur mustard and nitrogen mustard exposure.

Abstract
Mineral ballasting enhances carbon export from the surface to the deep ocean; however, little is known about the role of this process in the ice-covered Arctic Ocean. Here, we propose gypsum ballasting as a new mechanism that likely facilitated enhanced vertical carbon export from an under-ice phytoplankton bloom dominated by the haptophyte Phaeocystis. In the spring 2015 abundant gypsum crystals embedded in Phaeocystis aggregates were collected throughout the water column and on the sea floor at a depth below 2 km. Model predictions supported by isotopic signatures indicate that 2.7 g m−2 gypsum crystals were formed in sea ice at temperatures below −6.5 °C and released into the water column during sea ice melting. Our finding indicates that sea ice derived (cryogenic) gypsum is stable enough to survive export to the deep ocean and serves as an effective ballast mineral. Our findings also suggest a potentially important and previously unknown role of Phaeocystis in deep carbon export due to cryogenic gypsum ballasting. The rapidly changing Arctic sea ice regime might favour this gypsum gravity chute with potential consequences for carbon export and food partitioning between pelagic and benthic ecosystems.

Abstract
STUDY OBJECTIVE The 2 antidotes for acute cyanide poisoning in the United States must be administered by intravenous injection. In the out-of-hospital setting, intravenous injection is not practical, particularly for mass casualties, and intramuscular injection would be preferred. The purpose of this study is to determine whether sodium nitrite and sodium thiosulfate are effective cyanide antidotes when administered by intramuscular injection. METHODS We used a randomized, nonblinded, parallel-group study design in 3 mammalian models: cyanide gas inhalation in mice, with treatment postexposure; intravenous sodium cyanide infusion in rabbits, with severe hypotension as the trigger for treatment; and intravenous potassium cyanide infusion in pigs, with apnea as the trigger for treatment. The drugs were administered by intramuscular injection, and all 3 models were lethal in the absence of therapy. RESULTS We found that sodium nitrite and sodium thiosulfate individually rescued 100% of the mice, and that the combination of the 2 drugs rescued 73% of the rabbits and 80% of the pigs. In all 3 species, survival in treated animals was significantly better than in control animals (log rank test, P<.05). In the pigs, the drugs attenuated an increase in the plasma lactate concentration within 5 minutes postantidote injection (difference: plasma lactate, saline solution-treated versus nitrite- or thiosulfate-treated 1.76 [95% confidence interval 1.25 to 2.27]). CONCLUSION We conclude that sodium nitrite and sodium thiosulfate administered by intramuscular injection are effective against severe cyanide poisoning in 3 clinically relevant animal models of out-of-hospital emergency care.

Abstract
This work compared the toxicity of ZnO nanoparticles (ZnO-NPs), ZnO bulk, and ZnCl2 on microbial activity (C and N transformations and dehydrogenase and phosphatase activities) and their uptake and toxic effects (emergence, root elongation, and shoot growth) on three plant species namely wheat, radish, and vetch in a natural soil at 1000 mg Zn kg(-1). Additionally, plants were also tested at 250 mg Zn kg(-1). The effects of the chemical species on Zn extractability in soil were studied by performing single and sequential extractions. ZnCl2-1000 presented the highest toxicity for both taxonomic groups. For microorganisms, ZnO-NPs demonstrated adverse effects on all measured parameters, except on N transformations. The effects of both ZnO forms were similar. For plants, ZnO-NPs affected the growth of more plant species than ZnO bulk, although the effects were small in all cases. Regarding accumulation, the total Zn amounts were higher in plants exposed to ZnO-NP than those exposed to ZnO bulk, except for vetch shoots. The soil sequential extraction revealed that the Zn concentration in the most labile forms (water soluble (WS) and exchangeable (EX)) was similar in soil treated with ZnO (NP and bulk) and lower than that of ZnCl2-treated soil, indicating the higher availability of the ionic forms. The strong correlations obtained between WS-Zn fraction and the Zn concentrations in the roots, shoots, and the effects on shoot weight show the suitability of this soil extraction method for predicting bioavailable Zn soil for the three plant species when it was added as ZnO-NPs, ZnO bulk, or ZnCl2. In this work, the hazard associated with the ZnO-NPs was similar to ZnO bulk in most cases.

Abstract
The present study assessed the uptake and toxicity of ZnO nanoparticles (NPs), ZnO bulk, and ZnCl₂ salt in earthworms in spiked agricultural soils. In addition, the toxicity of aqueous extracts to Daphnia magna and Chlorella vulgaris was analyzed to determine the risk of these soils to the aquatic compartment. We then investigated the distribution of Zn in soil fractions to interpret the nature of toxicity. Neither mortality nor differences in earthworm body weight were observed compared with the control. The most sensitive end point was reproduction. ZnCl₂ was notably toxic in eliminating the production of cocoons. The effects induced by ZnO-NPs and bulk ZnO on fecundity were similar and lower than those of the salt. In contrast to ZnO bulk, ZnO-NPs adversely affected fertility. The internal concentrations of Zn in earthworms in the NP group were greater than those in the salt and bulk groups, although bioconcentration factors were consistently <1. No relationship was found between toxicity and internal Zn amounts in earthworms. The results from the sequential extraction of soil showed that ZnCl₂ displayed the highest availability compared with both ZnO. Zn distribution was consistent with the greatest toxicity showed by the salt but not with Zn body concentrations. The soil extracts from both ZnO-NPs and bulk ZnO did not show effects on aquatic organisms (Daphnia and algae) after short-term exposure. However, ZnCl₂ extracts (total and 0.45-μm filtered) were toxic to Daphnia.

Abstract
We have developed a therapeutic for the treatment of anthrax using an affinity-enhanced monoclonal antibody (ETI-204) to protective antigen (PA), which is the central cell-binding component of the anthrax exotoxins. ETI-204 administered preexposure by a single intravenous injection of a dose of between 2.5 and 10 mg per animal significantly protected rabbits from a lethal aerosolized anthrax spore challenge ( approximately 60 to 450 times the 50% lethal dose of Bacillus anthracis Ames). Against a similar challenge, ETI-204 administered intramuscularly at a 20-mg dose per animal completely protected rabbits from death (100% survival). In the postexposure setting, intravenous administration of ETI-204 provided protection 24 h (8 of 10) and 36 h (5 of 10) after spore challenge. Administration at 48 h postchallenge, when 3 of 10 animals had already succumbed to anthrax infection, resulted in the survival of 3 of 7 animals (43%) for the duration of the study (28 days). Importantly, surviving ETI-204-treated animals were free of bacteremia by day 10 and remained so until the end of the studies. Only 11 of 51 ETI-204-treated rabbits had positive lung cultures at the end of the studies. Also, rabbits that were protected from inhalational anthrax by administration of ETI-204 developed significant titers of PA-specific antibodies. Presently, the sole therapeutic regimen available to treat infection by inhalation of B. anthracis spores is a 60-day course of antibiotics that is effective only if administered prior to or shortly after exposure. Based upon results reported here, ETI-204 is an effective therapy for prevention and treatment of inhalational anthrax.

Abstract
Anthrax is considered a serious biowarfare and bioterrorism threat because of its high lethality, especially by the inhalation route. Rhesus macaques (Macaca mulatta) are the most commonly used nonhuman primate model of human inhalation anthrax exposure. The nonavailability of rhesus macaques necessitated development of an alternate model for vaccine testing and immunologic studies. This report describes the median lethal dose (LD(50)) and pathology of inhalation anthrax in cynomolgus macaques (Macaca fascicularis). Gross and microscopic tissue changes were reviewed in 14 cynomolgus monkeys that died or were killed after aerosol exposure of spores of Bacillus anthracis (Ames strain). The LD(50) and 95% confidence intervals were 61800 (34000 to 110000) colony-forming units. The most common gross lesions were mild splenomegaly, lymph node enlargement, and hemorrhages in various organs, particularly involving the meninges and the lungs. Mediastinitis, manifested as hemorrhage or edema, affected 29% of the monkeys. Microscopically, lymphocytolysis occurred in the intrathoracic lymph nodes and spleens of all animals, and was particularly severe in the spleen and in germinal centers of lymph nodes. Hemorrhages were common in lungs, bronchial lymph nodes, meninges, gastrointestinal tract, and mediastinum. These results demonstrate that the Ames strain of B. anthracis is lethal by the inhalation route in the cynomolgus macaque. The LD(50) of the Ames strain of B. anthracis was within the expected experimental range of previously reported values in the rhesus monkey in an aerosol challenge. The gross and microscopic pathology of inhalation anthrax in the cynomolgus monkey is remarkably similar to that reported in rhesus monkeys and humans. The results of this study are important for the establishment of an alternative nonhuman primate model for evaluation of medical countermeasures against inhalational anthrax.

Abstract
A model developed recently by Loisel and Stramski [Appl. Opt. 39, 3001-3011 (2000)] for estimating the spectral absorption a(lambda), scattering b(lambda), and backscattering b(b)(lambda) coefficients in the upper ocean from the irradiance reflectance just beneath the sea surface R(lambda, z = 0(-)) and the diffuse attenuation of downwelling irradiance within the surface layer ?K(d)(lambda)?(1) is compared with measurements. Field data for this comparison were collected in different areas including off-shore and near-shore waters off southern California and around Europe. The a(lambda) and b(b)(lambda) values predicted by the model in the blue-green spectral region show generally good agreement with measurements that covered a broad range of conditions from clear oligotrophic waters to turbid coastal waters affected by river discharge. The agreement is still good if the model estimates of a(lambda) and b(b)(lambda) are based on R(lambda, z = 0(-)) used as the only input to the model available from measurements [as opposed to both R(lambda, z = 0(-)) and ?K(d)(lambda)?(1) being measured]. This particular mode of operation of the model is relevant to ocean-color remote-sensing applications. In contrast to a(lambda) and b(b)(lambda) the comparison between the modeled and the measured b(lambda) shows large discrepancies. These discrepancies are most likely attributable to significant variations in the scattering phase function of suspended particulate matter, which were not included in the development of the model.

Abstract
The continuous changes in incident solar light occurring during the day oblige oxyphototrophs, such as the marine prokaryote Prochlorococcus, to modulate the synthesis and degradation rates of their photosynthetic components finely. How this natural phenomenon influences the diel expression of photosynthetic genes has never been studied in this ecologically important oxyphotobacterium. Here, the high light-adapted strain Prochlorococcus sp. PCC 9511 was grown in large-volume continuous culture under a modulated 12 h-12 h light-dark cycle mimicking the conditions found in the upper layer of equatorial oceans. The pcbA gene encoding the major light-harvesting complex showed strong diel variations in transcript levels with two maxima, one before the onset of illumination and the other near the end of the photoperiod. In contrast, the mRNA level of psbA (encoding the reaction centre II subunit D1), the monocistronic transcript of psbD (encoding D2) and the dicistronic transcript of psbDC were all tightly correlated with light irradiance, with a minimum at night and a maximum at noon. The occurrence of a second peak during the dark period for the monocistronic transcript of psbC (encoding one of the PS II core Chl a antenna proteins) suggested the involvement of post-transcriptional regulation. Differential expression of the external antenna and core genes may constitute a mechanism of regulation of the antenna size to cope with the excess photon fluxes that Prochlorococcus cells experience in the upper layer of oceans around midday. The 5' ends of all transcripts were mapped, and a conserved motif, 5'-TTGATGA-3', was identified within the putative psbA and pcbA promoters.

Abstract
Faba bean necrotic yellow virus (FBNYV) was not detected during 1994 to 1996 field surveys of faba beans (Vicia faba L.) in Spain (1). In 1997, however, one sample with symptoms of necrosis, collected in Baleares, was tested using ELISA (enzyme-linked immunosorbent assay) and was positive for both Tomato spotted wilt virus (TSWV) and FBNYV. FBNYV is a single-strand DNA virus that is transmitted by aphids and is the main virus disease of broad bean in North Africa and West Asia (2). During 1997 to 1999, faba bean plants with symptoms of necrosis, yellowing, small leaves, and stunting were collected from several fields in the Murcia Region (Spain) and were analyzed using ELISA. To detect FBNYV, we used monoclonal 2E9 supplied by H. J. Vetten (Institute of Plant Virology, Microbiology and Biosafety, BBA, Braunschweig, Germany). Of 700 samples analyzed, 34 were positive for FBNYV. Of the 34 positive samples, 12 tested positive, using commercial antiserum from Loewe, Inc. (Munich) for mixed infections with TSWV. FBNYV was transmitted to healthy faba bean plants by aphids (Acyrthosiphon pisum) in greenhouse experiments and was confirmed by ELISA. Preliminary epidemiological data showed a gradual increase in the number of plants infected with time in the same field. Aphid transmission of FBNYV to faba beans has established the disease in Spain and is a potential threat to other leguminous crops. This is the first report of a nanovirus in Europe.

Abstract
We report a new case of multiple vulvar fibroadenoma arising in a 47-year-old woman. This papillary and cystic lesion shares similarities with papilliferum hidradenoma and mammary fibroadenomas. After describing clinical and pathological characteristics, we try to detail its origin according to the literature and particularly its relationship with anogenital sweat glands and ectopic mammary glands.

Abstract
The occurrence of the acmA gene, encoding the lactococcal N-acetylmuramidase in new lactococcal isolates from raw milk cheeses, has been determined. Isolates were genotypically identified to the subspecies level with a PCR technique. On the basis of PCR amplification of the acmA gene, the presence or absence of an additional amplicon of approximately 700 bp correlated with Lactococcus lactis subspecies. L. lactis subsp. lactis exhibits both the expected 1,131-bp product and the additional amplicon, whereas L. lactis subsp. cremoris exhibits a single 1,131-bp fragment.

Abstract
Broad bean (Vicia faba L.) plants showing symptoms suggestive of viral infection, such as stunting, leaf roll, mosaic, chlorosis, necrosis, and yellowing, were observed in the Andalucia, Baleares, Cataluna, and Murcia regions of Spain. A 4-year field survey showed the presence of five viruses: bean leaf roll luteovirus (BLRV), beet western yellows luteovirus (BWYV), bean yellow mosaic potyvirus (BYMV), tomato spotted wilt tospovirus (TSWV), and cucumber mosaic cucumovirus (CMV). Identity of viruses was first determined by enzyme-linked immunosorbent assay and confirmed by at least one other method, such as inoculation to plant hosts, electron microscopy, molecular hybridization, or immunocapture-reverse transcriptase-polymerase chain reaction. Of the 250 samples assayed, 93 were positive for BYMV, 21 for BLRV, 10 for BWYV, 30 for TSWV, and 2 for CMV. Faba bean necrotic yellow virus (a single-strand DNA virus) and broad bean mottle bromovirus, which are widely distributed in the Mediterranean basin, were not detected in the samples analyzed. BYMV was distributed in all regions, whereas TSWV was restricted only to Mediterranean areas. To our knowledge, this is the first report of viruses infecting broad bean in Spain.

Abstract
Twenty percent of liquid tumors of the ovary are persistent functional cysts. Laboratory tests of the cystic fluid should make it possible to distinguish between functional cysts and organic cysts. In 170 patients derived from a multicenter study and presenting with a liquid tumor of the ovary (including 9% of cancers), samples of the cystic fluid and serum were taken from the patient and the ACE, CA 125, CA 19-9 markers, estradiol and Progesterone were assayed. The results of these assays were subjected to computerized analysis and compared with the pathological findings. The assays were able to discriminate between organic cysts and functional cyst with 93% of sensitivity and 95% specificity. The insufficient reliability of this evaluation justified a second study (in progress) which is limited to the study of pure fluid tumors with thin walls, no partitions, no vegetations and measuring less than 8 cm in diameter in which the incidence of cancers is very low. This study should fine tune the initial findings and result in a sensitivity approaching 100 percent. If this hypothesis is confirmed, it should be possible to include ultrasound-guided puncture carried out under closely defined conditions in the therapeutic decision trees for liquid cysts of the ovary.

Abstract
An enzyme immunoassay has been developed for quantitation of low levels of trout immunoglobulin (Ig). This assay uses two monoclonal antibodies, one as capture antibody and the other as detector, directed against two non-overlapping epitopes on the heavy chains of trout Ig. The assay shows high reproducibility and can detect 0.12 micrograms trout Ig ml-1. Coefficients of intra- and interassay variation ranged from 3.8 to 7.1% and from 7.9 to 17.4%, respectively. Analysis of 37 healthy trout showed increasing serum Ig concentration with size. The mean Ig concentration was 0.67 mg ml-1 for trout of about 20 g and 9.1 mg ml-1 for trout weighing more than 125 g.

Abstract
To induce deliberate hypotension during anesthesia, nicardipine was administered to patients undergoing total hip arthroplasty and was randomly compared with nitroprusside. Hemodynamic measurements were performed before and 10, 20, 30, and 60 min after starting to administer either nicardipine (n = 12) or nitroprusside (n = 12) (B, T1, T2, T3, and T4, respectively); at the end of drug infusion (T5); and 10, 20, and 60 min later (T6, T7, and T8, respectively). Plasma renin activity and catecholamine levels were measured at B, T1, T5, T6, and T7. In addition, plasma nicardipine concentration was measured in five patients at T1, T2, T5, T7, and T8. As with nitroprusside, nicardipine administration (1-3 micrograms.kg-1.min-1, after a titration dose of 4.7 +/- 1.5 mg) resulted in hypotension (up to -34% +/- 3%), a decrease in systemic vascular resistances (up to -49% +/- 4%), and increases in heart rate (up to +17% +/- 6%), cardiac index (up to +37% +/- 8%), plasma norepinephrine (up to +63% +/- 17%) and epinephrine (up to +232% +/- 68%) levels, and plasma renin activity (up to +336% +/- 207%). Ten and 20 minutes after discontinuation of the hypotensive drug, nicardipine led to persistent vasodilation and hypotension, which differed significantly from the hypertensive rebound observed after nitroprusside discontinuation, despite a similar increase in plasma renin activity and catecholamine levels. Our results indicate that after the infusion was terminated, the nicardipine-induced vasodilation was opposed to the vasoconstrictive effects of angiotensin II and catecholamines, thus avoiding hypertensive rebound.(ABSTRACT TRUNCATED AT 250 WORDS)
