Abstract
The Double Asteroid Redirection Test (DART) had an impact with Dimorphos (a satellite of the asteroid Didymos) on 26 September 20221. Ground-based observations showed that the Didymos system brightened by a factor of 8.3 after the impact because of ejecta, returning to the pre-impact brightness 23.7 days afterwards2. Hubble Space Telescope observations made from 15 minutes after impact to 18.5 days after, with a spatial resolution of 2.1 kilometres per pixel, showed a complex evolution of the ejecta3, consistent with other asteroid impact events. The momentum enhancement factor, determined using the measured binary period change4, ranges between 2.2 and 4.9, depending on the assumptions about the mass and density of Dimorphos5. Here we report observations from the LUKE and LEIA instruments on the LICIACube cube satellite, which was deployed 15 days in advance of the impact of DART. Data were taken from 71 seconds before the impact until 320 seconds afterwards. The ejecta plume was a cone with an aperture angle of 140 ± 4 degrees. The inner region of the plume was blue, becoming redder with increasing distance from Dimorphos. The ejecta plume exhibited a complex and inhomogeneous structure, characterized by filaments, dust grains and single or clustered boulders. The ejecta velocities ranged from a few tens of metres per second to about 500 metres per second.

Abstract
The Mediterranean Sea is among the three biodiversity hotspots of the world where elasmobranchs are severely threatened. Elasmobranchs act as apex or meso-predators within marine food webs and the loss/decline of apex predators determines the mesopredator release, leading in turn to increased predation on smaller prey. However, also several mesopredators (including rays, skates and small sharks) are intensively fished, being of commercial interest, or by-caught, and thus mesopredators increase could not be so evident. We analysed the trophic ecology of an endemic Mediterranean ray, the starry ray Raja asterias, at a seasonal scale from the Adriatic basin, one of the most intensively exploited area of the Mediterranean, by means of stomach contents and stable isotopes analyses. Our results evidenced that starry rays rely on benthic sources including species of local commercial values, such as swimming crabs, small cephalopods, and stomatopods and share the same trophic position with other elasmobranchs (rays, skates, and small sharks) and other mesopredators (e.g., common soles, Norway lobsters and mullets). As all mesopredators are overexploited, as well as their benthic prey are affected by intense trawl-fishing, the whole food webs are disrupted and neither the classical trophic cascade nor the mesopredator release hypothesis could be verified. Conservation measures for these species, such as the release after capture or the application of exclusion grids to the net, should be applied in areas where populations are strongly impacted by trawling.

Abstract
Clinical interpretation of changes in serial measurements of patients' HbA1c ought to be based on the knowledge of pre-analytical, analytical and intra-individual sources of variation that affect the results. The detectable change in HbA1c percentage depends on total analytical error. Since we have previously evidenced major problems in the routine use of HPLC, we compared a highly automated glycohemoglobin assay with the reference HPLC to solve the problem. The within- and between-run coefficients of variations ranged from 0.86 to 0.93%, and 2.51 to 2.12%, respectively, for the HPLC, and from 1.07 to 0.95, and 1.61 to 0.99% for the immunoturbidimetric assay. After HbA1c-assay calibration, the quality-control survey report of duplicate determinations performed on 20 consecutive days by both the HPLC and the immunologic method provided the expected mean values of control materials. The assay of 106 blood samples showed a minor yet significant bias of the immunoturbidimetric assay toward lower HbA1c. values (p 0.0001), as previously observed, although the two determination series resulted significantly correlated (r=0.96,p=0.0001). We conclude that the immunoturbidimetric assay is surely accurate, precise, and reproducible, and represents a valid alternative to the reference HPLC assay.

Abstract
The prevalence of coeliac disease (CD) in the adult population is unknown because silent and latent stages do exist. Type 1 diabetes mellitus may be associated with CD because of common genetic background and/or shared pathogenetic mechanisms. We investigated 74 adults with type 1 diabetes (32+/-11 yr, disease duration 13+/-9 yr), 69 parents of diabetic probands (56+/-10 yr), 59 siblings (30+/-11 yr) and 50 healthy controls (35+/-10 yr) for the presence of circulating islet cell antibodies (ICA), anti-glutamic acid decarboxylase antibodies (GADA65), anti-gliadin immunoglobulins A and G (IgA- and IgG-AGA). All patients with raised AGA, performed also IgA anti-endomysium antibody (EmA) indirect immunofluorescence assay. Samples were positive for ICA in 19 diabetics (26%), 4 parents (6%), 4 siblings (7%), 0 controls (p<0.001); for GADA in 34 diabetics (46%), 4 parents (6%), 1 sibling (2%), 0 controls (p<0.001). Twenty-five diabetic patients (34%), 10 parents (14%), 5 siblings (8%), 3 controls (6%) (p<0.001) had raised IgA-AGA (>4.4 mg/l). Four diabetic patients (5%), 5 parents (7%), 0 siblings (0%), 4 controls (8%) had raised IgG-AGA (>18 mg/l). Both IgA- and IgG-AGA were detected in 1 diabetic and 2 parents. The prevalence of ICA, GADA, and IgA-AGA positivity in Type 1 diabetes patients was significantly higher than in controls (p<0.001). Finally, 50 AGA-positive subjects performed EmA test: only 2 of them resulted EmA-positive, a diabetic patient and a sibling. The patient with Type 1 diabetes had a small-bowel biopsy specimen consistent with CD and, as sole evidence of malabsorption, sideropenic anaemia. EmA-positive sibling also showed severe iron deficiency, yet refused endoscopy. We conclude that: 1) CD cannot be diagnosed on the basis of associated IgA- and IgG-AGA alone. Nevertheless, detection of such antibodies is useful, in combination with EmA, in screening for endoscopic biopsy; 2) too high rate of detection of IgA-AGA in Type 1 diabetic patients in comparison with other groups excludes a false positivity of the test itself, while suggests a pathogenetic association of both immunological disorders, perhaps related to abnormal gammadelta TCR-bearing intraepithelial lymphocytes.

Abstract
A patient with normocytic anemia and marked and persistent reticulocytosis is presented. Causes responsible for blood loss and hemolytic diseases were excluded and, after bone marrow examination, myelodysplastic syndrome (refractory anemia) was diagnosed. In vitro reticulocyte survival studies suggested that reticulocytosis was a consequence of delayed maturation of the reticulocytes. Pseudoreticulocytosis may be an unusual presentation of myelodysplastic syndromes, because only 4 patients with such a finding have previously been reported.

Abstract
The aim of this study was to evaluate the usefulness of the measurement of urinary excretion of the brush-border enzyme gamma glutamyl-transferase (GGT), in comparison with that of alanine aminopeptidase (AAP), as a marker for tubular toxicity due to contrast media (CM). Urinary activities of AAP and GGT were measured prior to the administration of CM and 1, 3 and 5 days after in forty-nine adult renal patients undergoing a radiological examination with intravascular administration of CM. The behavior of GGT was similar to that of AAP. In fact, urinary activities of both AAP and GGT increased greatly after CM. This effect was maximal on the 1st day and statistically significant for both enzymes. Furthermore, on the 1st day a relevant increase of enzyme activity (at least +50% over the basal value) was observed in the same number of patients (67%) for AAP and GGT. The concordance between GGT and AAP variations was high and statistically significant. Finally, different variables (osmolarity, dose of CM, and baseline renal function of the patients) had a similar effect on urinary excretion of AAP and GGT. The repeatability of duplicated determinations of GGT resulted better than that of AAP. In conclusion, the good concordance of the results of GGT with those of AAP justifies the use of GGT as a marker for tubular effects due to CM. Furthermore, the measurement of GGT has a better repeatability than that of AAP.

Abstract
The aim of this study is to evaluate the effects of contrast media on both tubular and glomerular function. Different parameters of tubular and glomerular function were determined before and at 1, 3, and 5 days after the intravascular administration of contrast media in 100 adult renal patients (plasma creatinine 0.6-10.8 mg/dL, mean: 1.3). Urinary activities of five tubular enzymes (alanine aminopeptidase, gamma-glutamyltransferase, alkaline phosphatase, lactate dehydrogenase, N-acetyl-beta-D-glucosaminidase) increased significantly on the first day after the administration of contrast media, indicating a tubular damage. Glomerular filtration rate and the conventional tests of glomerular function (plasma creatinine, creatinine clearance, and urinary proteins) presented only slight variations after the administration of contrast media. In conclusion, contrast media principally affected the renal tubule (as demonstrated by enzymuria), while their effects on glomerular function were very mild.

Abstract
The effects of diltiazem (DTZ) treatment on blood pressure, renal function and renal hemodynamics over a six week period of therapy were evaluated in 14 adult patients with mild to moderate hypertension. Their creatinine clearances were 64 to 153 ml/min. After a week of treatment with placebo, DTZ was administered orally at a daily dose of 120 mg b.i.d. Blood pressure decreased from a mean value of 152/99 mm Hg (+/-13/6 SD) up to 144/91 (+/-17/8, P < 0.005) in the supine position and from 149/107 (+/-14/9) to 141/96 (+/-16/9, P < 0.005) in standing position. Heart rate decreased from 74 (+/-9) to 69 (+/-8). Plasma urea, creatinine, uric acid and their clearances as well as GFR and ERPF remained stable throughout the trial. Plasma glucose increased from 81 (+/-15) mg/dl to 98 (+/-30, P < 0.05) and plasma potassium decreased from 4.0 mEq/liter to 3.7 (+/-0.3, P < 0.005). Plasma cholesterol and triglycerides were unmodified. DTZ is an effective antihypertensive agent which does not significantly affect renal function. The effects on plasma glucose and potassium require periodical check-ups of these parameters.

Abstract
Renal disease patients often exhibit alterations in the lipid profile which may become an important risk of accelerated atherosclerosis and contribute to disease progression. Among such alterations, increased levels of lipoprotein(a) [Lp(a)] are common and may be related, in part, to the degree of proteinuria. Omega-3 polyunsaturated fatty acids (omega-3 FA) have been reported to decrease Lp(a) concentrations in nonrenal subjects. In addition, they have recently been shown to reduce proteinuria in patients with chronic glomerular disease. We therefore tested the hypothesis that omega-3 FA treatment in patients with chronic glomerular disease may reduce Lp(a) concentrations. Eight patients (2 with membranous glomerulonephritis, 6 with focal glomerular sclerosis) were submitted to a total of 13 six-week courses of treatment with omega-3 FA, at a dose of 3 g/day with a triglyceride preparation (n = 4) and of 7.7 g/day with an ethyl-ester preparation (n = 9). Both treatments significantly increased the proportions of omega-3 to omega-6 FA in total serum lipids, documenting compliance to treatment. Both treatments were also effective in decreasing serum thromboxane (from mean 490 +/- (SEM) 70 to 325 +/- 49 ng/ml, p < 0.05, in the high-dose group) and prolonging the bleeding time (from 5.8 +/- 0.4 to 7.7 +/- 0.5 min, p < 0.05, in the high-dose group), thus documenting the biological efficacy of treatment. However, despite a significant reduction in serum triglyceride levels (from 137 +/- 20 to 104 +/- 19 mg/dl in the high-dose group), Lp(a) concentrations did not change (292 +/- 120 U/l before, 315 +/- 130 U/l after the high-dose therapy). Treatment-related changes in proteinuria (from 2.9 +/- 0.5 to 2.1 +/- 0.7 g/24 h) were not related at all to changes in Lp(a) levels. We conclude that omega-3 FA do not decrease Lp(a) concentrations in renal patients with chronic glomerular diseases and that Lp(a) levels are unlikely to be related to the degree of proteinuria within the short-term modifications induced by omega-3 FA.

Abstract
We have compared the chemical and clinical characteristics of an immunonephelometric assay (INA), two immunoturbidimetric assays (ITA) and two semi-quantitative methods with those of a solid-phase radioimmunoassay (RIA) for measurement of urinary albumin (UA) concentration in 136 diabetic patients. INA and RIA had similar accuracy, and provided comparable results. However, RIA has slightly greater sensitivity than INA, which is easier and faster. Good agreement was also found between RIA and the two ITA methods, although one of these overestimated RIA values in the low-medium range (5-30 mg/l) of urinary albumin. ITA seems suitable for initial screening of albuminuria in diabetic patients but more sensitive procedures (such as RIA and INA) seem preferable for measurement of UA concentrations in the normal range. The two semi-quantitative methods showed high sensitivity but poor specificity, because of the large number of false positive results. About 50% of diabetic patients "positive" by these methods did not have microalbuminuria. The utility of these methods is questionable, because many samples from diabetic patients need to be reassayed by a more specific and sensitive assay such as the RIA, INA or ITA methods.

Abstract
UNLABELLED EFFICACY, renal effects and nephrotoxicity of the cephalosporin cefonicid (CEF) were evaluated in 11 adult patients with urinary tract infection and varying renal function (creatinine cl 19-161 ml/min, mean 75). CEF was administered i.m. for 7 days at a daily dose adjusted to renal function of the patients. EFFICACY At the 4th day and at the end of the treatment urine cultures were negative in all cases; a recurrence of the infection was observed in 4 patients 10 days after completion of therapy. Renal effects and nephrotoxicity: CEF neither modified plasma creatinine, urea, uric acid and their renal clearances nor glomerular filtration rate. Only the urinary enzyme activity of alanine aminopeptidase increased slightly at the end of the therapy. It returned to basal values in the post-treatment period. Urinary enzyme activities of gamma-glutamyltransferase, alkaline phosphatase, N-acetyl-beta-D-glucosaminidase and lysozyme were unmodified during and after treatment with CEF. These results indicate that CEF is an effective antimicrobial agent which does not influence renal function, nor cause nephrotoxic effects.

Abstract
We studied the rate of urinary excretion of albumin, alpha 1-microglobulin (as an indicator of the renal tubular involvement), sodium, potassium, and creatinine in the basal state (overnight urine collection) and after physical exercise (training session) in 10 professional cyclists, to verify whether protein excretion is increased even in well-trained athletes after physical effort. In addition, we wanted to understand whether the origin of exercise-induced proteinuria was glomerular, tubular, or both. Compared with the basal state (overnight collection), exercise significantly (P less than 0.01) increased the excretion rate of albumin (4.2 +/- 2.6 micrograms/min vs 18.1 +/- 10.6 micrograms/min, mean +/- SD), Na, and K, and also the urinary volume. Creatinine output was not affected by exercise. The mean (+/- SD) overnight excretion rate of albumin by athletes was quite similar to that found for 91 healthy nonathletes at rest (4.6 +/- 2.7 micrograms/min). The mean exercise-related excretion of alpha 1-microglobulin by the athletes significantly exceeded the overnight value (6.6 vs 0.3 mg/L, P = 0.037). Our study indicates that (a) albuminuria furnishes the greater contribution to the increase in exercise-induced proteinuria; (b) the exercise proteinuria is both glomerular and tubular in origin, and is reversible; (c) the enhanced protein requirement of athletes may in part be due to the recurrent excretion of proteins in the urine after physical effort.

Abstract
Renal function was assessed in 20 (11 female and 9 male, age 21-76 years, mean 53) renal patients with a creatinine clearance 25-145 ml/min, mean 95, to evaluate the effects of iohexol, a non-ionic low-osmolar contrast medium. Intravenous urography was performed in 16 patients and computed body tomography in 4, using a dose of iohexol ranged between 0.6-3.3 (mean 1.17) g/kg b.w. Different parameters of renal function were determined in the week preceding and 1, 3 and 5 days after the administration of iohexol. The principal renal effect of iohexol was an increase of urinary alanine aminopeptidase, gamma-glutamyltransferase, lactate dehydrogenase, alkaline phosphatase and N-acetyl-beta-D-glucosaminidase. The maximum increase of enzymuria was observed on day 1 after the administration of iohexol. In most cases enzymes returned to base-line values within 3 days. No relevant variation of renal hemodynamics (glomerular filtration rate and effective renal plasma flow) was observed after iohexol. In conclusion, iohexol can increase of urinary enzymes, but the effect is rapidly reversible and is not accompanied by a clinically significant impairment of renal hemodynamics.

Abstract
Serum levels of prealbumin, fibronectin, fibrinogen, alpha 1-acid glycoprotein, C-reactive protein, immunoglobulins, and white blood cell count were prospectively studied in 33 patients affected by polymyalgia rheumatica during the first 45 days of treatment with 6-methylprednisolone. Almost all parameters considered, except for fibronectin and IgM, settled within the normal range fairly quickly, while prealbumin showed a specular course compared with the other reactants. This behavior reflected the improvement of clinical symptoms registered in all patients after steroid treatment. Finally, the genesis of the low baseline prealbumin levels found in polymyalgia rheumatica/giant cell arteritis and their behavior during treatment are discussed.

Abstract
We have compared the chemico-clinical characteristics of an immuno-nephelometric technique (INA) with those of a solid-phase radioimmunoassay (RIA) method for the measurement of urinary albumin excretion (UAE) in diabetic patients. The UAE was evaluated in 227 diabetics; all, except 9, were Albustix-negative. The calibration of the nephelometer apparatus every time before the assay did significantly improve the accuracy and precision of the INA method. Similar values were obtained with the two methods (INA = 2.1 + 0.95 RIA, n = 227, r = 0.969) through all the ranges of albumin concentration explored. INA seems as suitable as RIA for the assay of UAE in diabetics. The two methods are comparably accurate and precise. However, RIA appears more sensitive than INA, while immunonephelometric system is easier and faster to perform (up to 200 samples can be assayed in about 1 hour, while 2-4 hours are necessary with RIA), with fewer handling steps. The INA instrumentation is automated and the reagents are more stable and less hazardous than those used in RIA. However, due to the cost of the nephelometer apparatus, the INA technique may be employed by those laboratories which have already this instrumentation or by those which will use it in the next future for the assay of other analytes in addition to albumin.

Abstract
Excretion of digoxin-like immunoreactivity (DLIS) was measured by RIA in timed overnight urine collections from 91 normotensive nondiabetic subjects and 104 normotensive insulin-dependent diabetic (IDDM) patients. The mean +/- SD DLIS excretion rate for the diabetic patients significantly exceeded that for the controls (73 +/- 41 vs 63 +/- 36 pg/min, P = 0.024). In both groups, the mean DLIS excretion rates for men were significantly higher (P = 0.0014, P = 0.006) than for women. In the controls, the DLIS excretion rate significantly correlated with the urinary excretion rate of creatinine (P less than 0.01), Na+ (P less than 0.05), and K+(P less than 0.05), and with the subjects' body weight (P less than 0.01), body mass index (P less than 0.05), and systolic blood pressure (P less than 0.05). In the diabetics, the DLIS excretion rate was significantly correlated with body weight (P less than 0.05) and with urinary excretion rates for albumin (P less than 0.01), creatinine (P less than 0.01), Na+ (P less than 0.05), and K+(P less than 0.05). Our data indicate that: (a) increased amounts of a cardiac glycoside-like substance (or a group of substances) are excreted in the urine of IDDM patients; (b) the urinary excretion of DLIS seems to depend on glomerular filtration rate and physiocochemical properties of glomerular membrane, as well as on subjects' body mass; and (c) because cardiac glycoside-like substances may increase peripheral vascular resistance, increased urinary excretion of DLIS by IDDM patients may indicate a tendency to develop hypertension.

Abstract
In order to verify whether measurement of plasma fibronectin (Fn) could represent a useful tool in acute-phase-response assessment, Fn was measured in 16 previously untreated patients (group A) affected by polymyalgia rheumatica giant cell arteritis (PMR-GCA), both before, during, and after 45 days of steroid therapy, and its course was compared with the behavior of some acute-phase reactants such as erythrocyte sedimentation rate (ESR), fibrinogen (Fng), and prealbumin (Preal). No difference was detected between the baseline Fn levels found in patients and those registered in a control group composed of 15 sex- and age-matched healthy subjects; no correlation was found with the other acute-phase parameters considered, and no significant variation of plasma Fn levels was registered as a result of the steroid therapy administered. On the contrary, all the other parameters revealed a good degree of correlation and tended progressively and homogeneously towards normalization as a result of the therapy administered. Plasma Fn was also measured in another group of 16 PMR-GCA patients (group B), all of whom had pathological retinal fluoroangiographic findings, and its levels were compared with those of the von Willebrand factor antigen (vWfAg), a biochemical index of vascular damage. While the levels of Fn continued to be the same as those detected in the control group, the values of vWfAg registered in group B proved to be significantly different from those found in another homogeneous control group of 25 healthy subjects. Finally, no correlation could be detected between Fn and vWfAg, and neither of them showed any significant correlation with the ESR.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Renal artery embolism is not a rare occurrence, especially in patients with valvular heart disease, but the early diagnosis of this condition is infrequently accomplished. We report the clinical and laboratory data of 2 patients with valvular heart disease who presented with unilateral renal artery embolization. The usefulness of the determination of serum and urinary enzymes and renal function tests is discussed. We propose that these parameters support an earlier and more accurate diagnosis of renal artery embolism.

Abstract
A clinical and electrophysiological follow up study of 14 cases of hemopathic patients patients undergoing VCR therapy showed evidence that the drug has a direct action on the motor and sensory axon but not on the propagation velocity. Sensory nerves seem to be affected earlier and more than motor ones. Correlation was good between clinical and electrophysiological findings for both functions. The findings in man correspond with the animal data and therefore lead to the conclusion that VCR polyneuropathy is due to an involvement of the nerve axon.
