Abstract
The study aimed to evaluate the impact of listening to preferred music during active/passive rest on power output and heart rate in barbell squats (BS) and bench presses (BP). Fifteen participants (13 males and 2 females), moderately resistance trained, were engaged in four randomized experimental sessions with varying rest intervals (active/passive) and music presence (listening or not). Each session involved three sets of three repetitions of BS and BP at a 50% one-repetition maximum. ANOVA showed a significant main effect of the set for BP relative mean and peak power output (p < 0.001; both). The post hoc comparisons indicated a significantly higher BP relative mean and peak power output in set_2 (p < 0.001; effect size [ES] = 0.12 and p < 0.001; ES = 0.10) and set_3 (p < 0.001; ES = 0.11 and p = 0.001; ES = 0.16) in comparison to set_1. Moreover, a main effect of the set indicating a decrease in BS relative peak power output across sets was observed (p = 0.024) with no significant differences between sets. A significantly higher mean heart rate during active rest in comparison to passive rest was observed (p = 0.032; ES = 0.69). The results revealed no significant effect of listening to music on relative power output and heart rate during BS and BP.

Abstract
Introduction: This study examined the effects of blood flow restriction (BFR) and reperfusion on the mechanical properties of the rectus femoris muscle at rest (frequency and stiffness). Methods: Fourteen trained men (body weight = 81.0 ± 10.3 kg; BMI = 25 ± 3.0 m/kg2; height = 181 ± 4 cm; training experience = 6.0 ± 2.2 years) participated in an experimental session involving their dominant (BFR) and non-dominant leg (control). Muscle mechanical properties were measured using Myoton's accelerometer at the midpoint of the rectus femoris muscle at five time points. In the BFR leg, an 80% arterial occlusion pressure was applied by a cuff for 5 min. No cuff was applied in the control leg. Femoral Myoton measurements were taken from both legs 2 and 4 min after the start of BRF as well as 30 s and 2 min after the end of the occlusion period. Results: The two-way ANOVA revealed a statistically significant interaction effect for stiffness and frequency (p < 0.001; η2 > 0.67). The post hoc analysis showed that both stiffness and frequency increased during BFR compared with rest and then dropped to the resting levels post BFR period. Also, stiffness and frequency were higher than control only during the BFR period, and similar during rest and post BFR. Conclusion: These results indicate that the application of BFR at rest leads to significant changes in mechanical properties of the rectus femoris muscle.

Effects of Flywheel vs. Free-Weight Squats and Split Squats on Jumping Performance and Change of Direction Speed in Soccer Players. Sports (Basel) 2023; 11:124.

Abstract
The objective of this study was to compare (i) The effects of a flywheel and free-weight resistance training program; and (ii) The effects of performing lateral and frontal split squats as part of a flywheel-resistance training program on jumping performance, the 5-0-5 change of direction test time, and the one-repetition maximum (1RM) back squat in soccer players. Twenty-four male amateur soccer players participated in this study and were randomly and equally assigned to one of three different test groups: forward split-squat group (FSQ); lateral split-squat group (LSQ); and free-weight training group (TRAD). Athletes in the FSQ group performed a squat and a forward split squat on a flywheel device, while those in the LSQ group performed a squat and a lateral split squat (instead of a forward split squat) on a flywheel device. Each training lasted 4 weeks. The main finding was that all training groups, such as TRAD, FSQ, and LSQ, significantly improved broad jump length (p = 0.001; effect size [ES] = 0.36), 5-0-5 COD time with a turn on the dominant limb (p = 0.038; ES = 0.49), and 1RM back squat (p = 0.001; ES = 0.4). In turn, both flywheel-resistance training groups (FSQ and LSQ) significantly improved their counter-movement jump height (p = 0.001; ES = 0.8 and p = 0.002; ES = 0.58; respectively) with no effect in the TRAD (p = 0.676; ES = 0.07) training group. Both free-weight and flywheel-resistance training lasting 4 weeks performed in-season contributed to significant improvement in 1RM back squat, broad jump performance, and 5-0-5 change of direction testing time, while flywheel-resistance training might be superior in counter-movement jump height enhancement in soccer players. Moreover, the manner in which split squats were performed was not a factor influencing the obtained results.

Abstract
The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×10^{20} protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by ≃17% systematic rather than the ≃7.4% statistical uncertainties. The double-differential cross section in final-state electron energy and angle is presented for the first time, together with the single-differential dependence on Q^{2} (squared four-momentum transfer) and energy, in the range 1 GeV≤E_{ν}<6 GeV. Detailed comparisons are made to the predictions of the GENIE, GiBUU, NEUT, and NuWro neutrino event generators. The data do not strongly favor a model over the others consistently across all three cross sections measured, though some models have especially good or poor agreement in the single differential cross section vs Q^{2}.

Abstract
Despite the many health benefits of resistance training, it has been suggested that high-intensity resistance exercise is associated with acute increases in intraocular pressure which is a significant risk factor for the development of glaucomatous optic nerve damage. Therefore, resistance training using a variety of forms (e.g., resistance bands, free weights, weight machines, and bodyweight) may be harmful to patients with or at risk of glaucoma. An appropriate solution for such people may involve the combination of resistance training and blood flow restriction (BFR). During the last decade, the BFR (a.k.a. occlusion or KAATSU training) method has drawn great interest among health and sports professionals because of the possibility for individuals to improve various areas of fitness and performance at lower exercise intensities. In comparison to studies evaluating the efficiency of BFR in terms of physical performance and body composition changes, there is still a paucity of empirical studies concerning safety, especially regarding ocular health. Although the use of BFR during resistance training seems feasible for glaucoma patients or those at risk of glaucoma, some issues must be investigated and resolved. Therefore, this review provides an overview of the available scientific data describing the influence of resistance training combined with BFR on ocular physiology and points to further directions of research.

Abstract
This Letter reports results from the first long-baseline search for sterile antineutrinos mixing in an accelerator-based antineutrino-dominated beam. The rate of neutral-current interactions in the two NOvA detectors, at distances of 1 and 810 km from the beam source, is analyzed using an exposure of 12.51×10^{20} protons-on-target from the NuMI beam at Fermilab running in antineutrino mode. A total of 121 of neutral-current candidates are observed at the far detector, compared to a prediction of 122±11(stat.)±15(syst.) assuming mixing only between three active flavors. No evidence for ν[over ¯]_{μ}→ν[over ¯]_{s} oscillation is observed. Interpreting this result within a 3+1 model, constraints are placed on the mixing angles θ_{24}<25° and θ_{34}<32° at the 90% C.L. for 0.05 eV^{2}≤Δm_{41}^{2}≤0.5 eV^{2}, the range of mass splittings that produces no significant oscillations at the near detector. These are the first 3+1 confidence limits set using long-baseline accelerator antineutrinos.

Abstract
The main aim of the present study was to evaluate the acute effects of ischemia used during rest periods on bar velocity changes during the bench press exercise at progressive loads, from 20 to 90% of 1RM. Ten healthy resistance trained men volunteered for the study (age = 26.3 ± 4.7 years; body mass = 89.8 ± 6.3 kg; bench press 1RM = 142.5 ± 16.9 kg; training experience = 7.8 ± 2.7 years). During the experimental sessions the subjects performed the bench press exercise under two different conditions, in a randomized and counterbalanced order: (a) ischemia condition, with ischemia applied before the first set and during every rest periods between sets, and (b) control condition where no ischemia was applied. During each experimental session eight sets of the bench press exercise were performed, against loads starting from 20 to 90% 1RM, increased progressively by 10% in each subsequent set. A 3-min rest interval between sets was used. For ischemia condition the cuffs was applied 3 min before the first set and during every rest period between sets. Ischemia was released during exercise. The cuff pressure was set to ∼80% of full arterial occlusion pressure. The two-way repeated measures ANOVA showed a statistically significant interaction effect for peak bar velocity (p = 0.04) and for mean bar velocity (p = 0.01). There was also a statistically significant main effect of condition for peak bar velocity (p < 0.01) but not for mean bar velocity (p = 0.25). The post hoc analysis for interaction showed significantly higher peak bar velocity for the ischemia condition compared to control at a load of 20% 1RM (p = 0.007) and at a load of 50% 1RM (p = 0.006). The results of the present study indicate that ischemia used before each set even for a brief duration of <3 min, has positive effects on peak bar velocity at light loads, but it is insufficient to induce such effect on higher loads.

Abstract
This study evaluated the effects of ischemic conditioning on power output and bar velocity in the bench press exercise. Ten healthy males (age: 25 ± 2 years; body mass: 92 ± 8 kg; bench press one repetition maximum -1RM: 145 ± 13 kg), took part in two experimental sessions (with and without ischemia), 1 week apart in random and counterbalanced order. In the ischemic condition, cuffs placed around the upper part of the arms were inflated to 80% of arterial occlusion pressure before each set, while in the control condition there was no blood flow restriction. The exercise protocol included 5 sets of three repetitions each, against a resistance equal to 60% 1RM, with 5 min recovery intervals between sets. There was a main effect of condition for mean power output (MP) and mean bar velocity (MV) (p = 0.01), with overall MP being higher in ischemia than in control by 5.6 ± 4.1% (mean ± 90% compatibility limits), a standardized effect size (ES) of 0.51. Overall MV was also higher by 5.5 ± 4.0%, ES = 0.63. Peak power output (PP) and peak bar velocity (PV) were similar in set 1 of the control and ischemia condition (1039 ± 105 vs. 1054 ± 82 W; 684 ± 74 vs. 696 ± 53 W; 1.09 ± 0.07 vs. 1.12 ± 0.09 m/s; 0.81 ± 0.05 vs. 0.82 ± 0.05 m/s, p = 0.67 to 0.99, mean ± standard deviation). However, from set 3 onward (p = 0.03 to 0.001), PP and PV were higher in ischemia compared with control, with the highest difference observed in set 5 (10.9 ± 5.9%, ES = 0.73 for PP and 8.6 ± 4.6%; ES = 0.89 for PV). These results indicate that ischemia used before each set of the bench press exercise increases power output and bar velocity and this may be used as performance-enhancing stimulus during explosive resistance training.

Abstract
In this study, we examined the impact of contrast movement tempo (fast vs. slow) on power output and bar velocity during the bench press exercise. Ten healthy men (age = 26.9 ± 4.1 years; body mass = 90.5 ± 10.3 kg; bench press 1RM = 136.8 ± 27.7 kg) with significant experience in resistance training (9.4 ± 5.6 years) performed the bench press exercise under three conditions: with an explosive tempo of movement in each of three repetitions (E/E/E = explosive, explosive, explosive); with a slow tempo of movement in the first repetition and an explosive tempo in the next two repetitions (S/E/E = slow, explosive, explosive); and with a slow tempo of movement in the first two repetitions and an explosive tempo in the last repetition (S/S/E = slow, slow, explosive). The slow repetitions were performed with a 5/0/5/0 (eccentric/isometric/concentric/isometric) movement tempo, while the explosive repetitions were performed with an X/0/X/0 (X- maximal speed of movement) movement tempo. During each experimental session, the participants performed one set of three repetitions at 60%1RM. The two-way repeated measures ANOVA showed a statistically significant interaction effect for peak power output (PP; p = 0.03; η2 = 0.26) and for peak bar velocity (PV; p = 0.04; η2 = 0.24). Futhermore there was a statistically significant main effect of condition for PP (p = 0.04; η2 = 0.30) and PV (p = 0.02; η2 = 0.35). The post hoc analysis for interaction revealed that PP was significantly higher in the 2nd and 3rd repetition for E/E/E compared with the S/S/E (p < 0.01 for both) and significantly higher in the 2nd repetition for the S/E/E compared with S/S/E (p < 0.01). The post hoc analysis for interaction revealed that PV was significantly higher in the 2nd and 3rd repetition for E/E/E compared with the S/S/E (p < 0.01 for both), and significantly higher in the 2nd repetition for the S/E/E compared with the S/S/E (p < 0.01). The post hoc analysis for main effect of condition revealed that PP and PV was significantly higher for the E/E/E compared to the S/S/E (p = 0.04; p = 0.02; respectively). The main finding of this study was that different distribution of movement tempo during a set has a significant impact on power output and bar velocity in the bench press exercise at 60%1RM. However, the use of one slow repetition at the beginning of a set does not decrease the level of power output in the third repetition of that set.

Abstract
The aim of the present study was to evaluate the effects of external compression with blood flow restriction on power output and bar velocity changes during the back-squat exercise (SQ). The study included 10 judo athletes (age = 28.4 ± 5.8 years; body mass = 81.3 ± 13.1 kg; SQ one-repetition maximum (1-RM) 152 ± 34 kg; training experience 10.7 ± 2.3 years). Methods: The experiment was performed following a randomized crossover design, where each participant performed three different exercise protocols: (1) control, without external compression (CONT); (2) intermittent external compression with pressure of 100% arterial occlusion pressure (AOP) (EC-100); and (3) intermittent external compression with pressure of 150% AOP (EC-150). To assess the differences between conditions, the participants performed 3 sets of 3 repetitions of the SQ at 70% 1-RM. The differences in peak power output (PP), mean power output (MP), peak bar velocity (PV), and mean bar velocity (MV) between the three conditions were examined using repeated measures two-way ANOVA. Results: The post hoc analysis for the main effect of conditions showed a significant increase in PP (p = 0.03), PV (p = 0.02), MP (p = 0.04), and MV (p = 0.03), for the EC-150, compared to the CONT. Furthermore, a statistically significant increase in PP (p = 0.04), PV (p = 0.03), MP (p = 0.02), and MV (p = 0.01) were observed for the EC-150 compared to EC-100. There were no significant changes in PP, PV, MP, and MV, between EC-100 and CONT conditions. Conclusion: The results indicate that the use of extremely high-pressure external compression (150% AOP) during high-loaded (70% 1-RM) lower limb resistance exercise elicits an acute increase in power output and bar velocity.

Abstract
Abstract
Objectives
The purpose of this study was to investigate the central activity of the two new imidazo[2,1-f]purine-2,4-dione derivatives behaved as presynaptic 5HT1A receptor agonists and postsynaptic 5HT1A, 5HT2A and D2 receptors antagonists. The compounds were examined using animal tests towards antipsychotic, antidepressant- and anxiolytic-like properties and then compared with effects evoked by an atypical antipsychotic drug ziprasidone.
Methods
D-amphetamine-induced hyperactivity test was used to determine antipsychotic-like activity of compounds 7 and 9. The forced swim test (FST) and the four-plate test were conducted to investigate antidepressant- and antianxiety-like activity, respectively, of studied agents. The investigated compounds 7, 9 and ziprasidone were administered intraperitoneally 60 min before the tests. Diazepam and imipramine were used as standard anxiolytic and antidepressant drugs, respectively.
Key findings
The obtained results demonstrate that new synthesized compound 9 evokes antipsychotic-like activity alike ziprasidone and, in contrary to the antipsychotic drug, shows antidepressant- and anxiolytic-like properties in behavioural tests in mice.
Conclusions
The present preclinical results indicate that one of the two investigated imidazo[2,1-f]purine-2,4-dione derivatives, compound 9, with methyl group at 7 position of imidazo[2,1-f]purine-2,4-dione fragment and the ortho-OCH3 substituent in the aryl moiety, acts as an antipsychotic drug with additional antidepressant and anxiolytic properties.

Abstract
The success of acute stroke treatment is first and foremost time-dependent, and the need for improvement in acute stroke management is demonstrated by the fact that only a minority of patients gain access to treatment - in particular, intravenous recombinant tissue plasminogen activator (IV tPA) - within the necessary time window. Standards of acute stroke care vary widely both regionally and nationally; consequently, various healthcare organizations have undertaken initiatives to measure and improve quality of care. To date, most quality measures have been process-based, focusing primarily on metrics of patient care in the acute hospital-based setting (e.g., time to recombinant tPA administration). Therefore, there remains a need for metrics designed to assess how improvements in process translate into patient outcomes. A global forum was convened to share best practice and provide consensus recommendations on core metrics for measuring improvements in access to care and patient outcomes. Recommendations for core metrics of patient outcomes include hospital-based outcomes (e.g., neurological status at 24 h, ambulatory status at discharge) and post-discharge outcomes (e.g., modified Rankin Scale score at 30 and/or 90 days). Recommendations for best practice relating to aspects of people, process, and technology involved in the stroke treatment pathway that may help provide improvements in these core outcome measures are also outlined.

Abstract
Different MR imaging patterns of cerebral fat embolism have been reported in the literature without a systematic review. Our goal was to describe the patterns, explore the relationship between disease course and the imaging patterns, and discuss the underlying mechanism. We reveal 5 distinctive MR imaging patterns: 1) scattered embolic ischemia occurring dominantly at the acute stage; 2) confluent symmetric cytotoxic edema located at the cerebral white matter, which mainly occurs at the subacute stage; 3) vasogenic edematous lesions also occurring at the subacute stage; 4) petechial hemorrhage, which persists from the acute to the chronic stage; and 5) chronic sequelae, occurring at late stage, including cerebral atrophy, demyelinating change, and sequelae of infarction or necrosis. Underlying mechanisms of these imaging patterns are further discussed. Recognition of the 5 evolving MR imaging patterns of cerebral fat embolism may result in adjustment of the appropriate management and improve the outcome.

Abstract
We describe the re-siting of ventriculoperitoneal shunts to the gallbladder in two children. The first child had a rare case of hydrocephalus associated with plasminogen deficiency. She had had multiple VP shunt revisions due to non-absorption of CSF from the peritoneum. The second had craniopharyngioma-related hydrocephalus with once again a non-absorbing peritoneum. We report no surgical complications in the revisions for both the cases, and there has been a subsequent follow-up of 46 and 28 months, respectively, without incident. A review of the relevant literature describing the use and the performance of ventriculocholecystic shunts in comparison with other ventricular shunts is considered.

Abstract
The importance of lowering blood pressure in hypertensive subjects is well known but the relationship between hypertension and cognitive function has been a subject of considerable controversy. Cross-sectional studies investigating the relationship between blood pressure and cognition have shown conflicting relationships whilst the majority of longitudinal studies have demonstrated elevated blood pressure to be associated with cognitive decline. Randomised studies have demonstrated heterogeneous and sometimes conflicting effects of blood pressure lowering on cognitive function and suggested reasons include multiple mechanisms by which hypertension affects the brain, the variety of cognitive instruments used for assessment and differences in antihypertensive treatments. Chronic hypertension accelerates arteriosclerotic changes in the brain with a disproportionate effect on subcortical circuits associated with cerebral small vessel disease. Randomised clinical trials assessing the cognitive consequences of blood pressure reduction in people with small vessel disease are lacking and many of the existing controversies on the cognitive consequences of blood pressure lowering, especially in older people, arise from the design limitations of studies. This article describes the methodological issues in designing such a trial and the results of a pilot evaluation to see if careful selection of subjects and measurements would make undertaking intervention studies feasible. Given the predicted upswing in people with cognitive impairments, the time is right for randomised clinical trials with specific cognitive end-points to examine the relationship between cognitive function and hypertension and guide practice.

Abstract
BACKGROUND It has been suggested that impaired cerebral autoregulation and vasodilatory capacity may play in role in the pathogenesis of the leukoaraiosis seen in small vessel disease. Adequate perfusion of the deep white matter of the brain depends on the relationships between blood pressure (BP), cerebral vasoreactivity and autoregulation. METHODS 24 h ambulatory BP measurement, quantitative volumetric MRI analysis of white matter lesion (WML) volume and transcranial Doppler ultrasound assessments of CO(2) reactivity in response to hypercapnia and dynamic cerebral autoregulatory index (ARI) were undertaken in 64 patients with cerebral small vessel disease. RESULTS Subjects had mean 24 h BP 133/76 mm Hg (SD 13/9), median WML volume 7169 (IQR 20497) mm(3), mean CO(2) reactivity 83.6 (SD 37.4)% and mean ARI 5.6 (SD 1.4) (range 0-9). In multivariate models, after adjusting for age, gender, vascular risk profile and WML volume, ARI correlated with 24 h mean BP levels (R(2) = 0.127, t = 2.440, p = 0.019) and CO(2) reactivity correlated with duration of hypertension (R(2) = 0.085, t = -2.244, p = 0.029). In individuals with hypertension for more than 10 years, ARI also correlated with nocturnal BP dipping (r = 0.806, p = 0.002). ARI and CO(2) reactivity were unaffected by WML volumes, and ARI and CO(2) reactivity were unrelated. CONCLUSION Cerebral autoregulation and CO(2) reactivity are two distinct processes which are not related to WML volume but are related to BP levels and duration of hypertension, respectively. Greater nocturnal dipping was associated with higher ARI values, suggesting preservation of autoregulation in patients with increased vulnerability to reduced cerebral perfusion.

Abstract
INTRODUCTION Clinical islet transplantation is increasingly regulated, with isolation standards defined under current good manufacturing practices (cGMPs). cGMP requires validation of equipment cleaning and sterilization. The automated process for islet isolation requires rapid thermal exchange during processing, manipulating a metal coil containing cellular product into and out of chilled/heated waterbaths. We recognize challenges of validating cleaning and sterilization of this coil and propose replacement with a disposable blood warming system. Our specific aims were to assess the system's ability to accommodate flow rates utilized during various phases of pancreatic digestion and to assess its efficiency of heat exchange and temperature control. METHODS In a pancreas digestion circuit, heat exchange occurred via the coil in a digital water bath, or Warmflo blood warming bag in a digital warming unit. Temperature within the digestion chamber was assessed using an inserted thermocouple. Time to achieve 37 degrees C was measured for set heating element temperatures 38.5 degrees C to 41 degrees C. Circuit temperature maintenance characteristics were also recorded. RESULTS The Warmflo bloodbag easily accommodated flows of 150 and 300 mL/min. At all set temperatures, the bag resulted in shorter or equivalent time to 37 degrees C than the coil. Maintenance of 37 degrees C was also equivalent. We have utilized this system for four human islet isolations with mean time to 37 degrees C of 5.5 minutes, without difference in digestion quality. CONCLUSIONS Use of a disposable blood warming system in place of the coil during islet isolation provides adequate flow characteristics, heat exchange, and temperature control and may facilitate evolution of islet isolation toward cGMP compliance.

Abstract
The quality of pain relief during the first 24 hours following day case surgery has been poorly documented. This study was conducted to evaluate the quality of postoperative pain relief when using dexibuprofen or paracetamol. 127 patients in the age group 17-78 who underwent day case surgery were asked to complete questionnaire 24 hours after the end of the operation. The majority of patients (74,02%) had pain after operation. 66,14% had only mild pain (VAS 1-5), 7,87% had difficulty in sleeping at night due to severe pain (VAS 6-8). In 88,89% of outpatients the use of dexibuprofen or paracetamol was effective with pain relief.

Abstract
AIMS Papillary meningioma is a rare meningeal tumour. To date only a few cases have been reported and their immunohistochemical features have not been fully documented. METHODS AND RESULTS A 49-year-old woman presented with a 2-month history of headaches and memory disturbance. CT and MRI imaging showed an enhancing pineal mass with extension into the occipital lobes and invasion of the splenium. At surgery, the tumour was found to be tough and vascular with a well-defined capsule. No recurrence was noted 19 months after the operation. In another case a 44-year-old woman was admitted with 1-month history of headaches, poor memory, imbalance and diplopia. CT scan showed a large hyperdense, uniformly, enhancing mass within the middle cranial fossa at the petrous ridge. The tumour recurred 19 and 25 months after first resection. The histology of both tumours was similar. The neoplasms contained polygonal cells with a moderate amount of cytoplasm, rounded regular nuclei and distinct cell borders. The cells were arranged radially around the blood vessels (perivascular pattern) and a papillary pattern was seen only focally. Mitotic figures were moderately frequent. Immunohistochemistry showed that both tumours were immunoreactive to vimentin and NSE, whereas GFAP, CAM5.2, EMA, S100 protein and synaptophysin were negative. Electron microscopy revealed interdigitating cell processes, desmosomes and intermediate filaments. CONCLUSIONS The histological and immunohistochemical features of these two tumours are complex and difficult to interpret. Although papillary meningiomas were considered in our initial differential diagnosis, the final conclusion was possible only when the ultrastructural features were revealed.

Abstract
The authors report two adult patients with chronic temporal lobe epilepsy and pathologic features consistent with Rasmussen's encephalitis. Although seizures persisted after temporal lobe surgery no progressive cognitive or neurologic deficit has emerged. Prominent auditory auras in each suggested a persisting epileptogenic focus in the superior temporal gyrus. The current findings expand the clinical spectrum of Rasmussen's encephalitis and suggest that chronic nonprogressive encephalitis may serve as the pathologic substrate of medically intractable temporal lobe epilepsy.

Abstract
Advances in biochemistry and molecular biology have made it possible to identify a number of mechanisms active in the immune phenomena of echinoderms. It is obvious that echinoderms have the ability to distinguish between different foreign objects (pathologically changed tissues, microorganisms, parasites, grafts) and to express variable effector mechanisms which are elicited specifically and repeatably after a variety of non-self challenges. The molecular and biochemical basis for the expression of these variable defense mechanisms and the specific signals which elicit one type of effector mechanism are not, however, yet well known. The high capacity of coelomocytes to phagocytose, entrap and encapsulate invading microorganisms is a valid immune cell-mediated mechanism of echinoderms. The entrapped bacteria, discharged cellular materials and disintegrating granular cells are compacted and provoke the cellular encapsulation reaction. Moreover, humoral-based reactions form an integral part of the echinoderm defense system against microbial invaders. Factors such as lysozyme, perforins (hemolysins) vitellogenin and lectins are normal constituents of hemolymph, while cytokines are synthesized by echinoderms in response to infection.

Abstract
OBJECTIVE Issues surrounding the nature of the edema associated with traumatic brain injury in humans, and its evolution in the acute phase, remain unresolved. This study aimed to characterize the topographical nature of the pathophysiological changes in human traumatic brain injury with diffusion tensor magnetic resonance imaging. METHODS Multislice diffusion-weighted magnetic resonance imaging data were acquired from five patients undergoing elective ventilation for management of traumatic focal contusion or hematomas. The diffusion tensor and the T2-weighted intensity were then computed for every voxel in the image data set for each patient. The topographical distribution of abnormalities in the trace of the diffusion tensor and T2-weighted images were characterized by cluster analysis. RESULTS In four patients with technically satisfactory data, a narrow band of tissue was observed in the periphery of focal lesions, which was characterized by selective reduction in the trace of the diffusion tensor, without any associated increase in the T2-weighted signal intensity. CONCLUSION This change is interpreted as indicating either a partial redistribution of water from the extra- to intracellular compartment, or a reduction in the diffusivity of water in the intracellular or cytosolic environment. These diffusion and T2-weighted characteristics are also found in early ischemic change, hence, such regions may represent potentially salvageable tissue at risk of permanent damage. The study illustrates the advantage of using information contained within the diffusion tensor in addition to more conventional imaging sequences.

Abstract
OBJECTIVE To assess the clinical implications and the pathophysiologic determinants of interictal bitemporal hypometabolism (BTH) in temporal lobe epilepsy (TLE) not associated with bilateral MRI abnormalities or intracranial space-occupying lesions. METHODS The authors compared the clinical, interictal, and ictal EEG, Wada test, and neuropsychology data of 15 patients with intractable complex partial seizures of temporal lobe origin and BTH with those of 13 consecutive patients with unilateral TLE associated with unilateral temporal hypometabolism (UTH) who remained seizure free for more than 3 years after anterior temporal lobectomy. 18F-fluorodeoxyglucose PET scans were analyzed visually and semiquantitatively, and ratios of counts in individual temporal areas to the rest of the cerebrum were compared with the corresponding values from 11 normal control subjects and with the nonepileptogenic hemisphere of the 13 patients with UTH. BTH was defined as more than 2.5 SDs below control values for two or more temporal areas on each side irrespective of any asymmetry. RESULTS BTH reflected bilateral independent seizure onset in eight patients (53%). The topography of the metabolic depression was not a reliable predictor of epileptogenicity, but involvement of the inferior temporal gyrus was related specifically to ipsilateral seizure onset (70% sensitivity, 100% specificity). In patients with unilateral TLE, contralateral hypometabolism was associated with longer disease duration and worst memory performance during the Wada test, which amounted to global amnesia after ipsilateral injection in three patients, precluding surgical treatment. Contralateral seizure spread in the ictal EEG was significantly faster in patients with BTH. CONCLUSIONS In TLE, symmetric or asymmetric BTH may signal bilateral independent seizure onset in approximately half the patients, especially when involving the inferior temporal gyrus. Alternatively, it may reflect an advanced stage of the disease process, characterized by a breakdown of the inhibitory mechanisms in the contralateral hemisphere, and secondary memory deficit associated with higher risk of postoperative memory decline. Patients with TLE and BTH but without bilateral MRI changes may still be operated on successfully, but surgical suitability should be proved by comprehensive intracranial EEG studies and Wada test.

Abstract
A specific extracellular proteinase, degrading selectively the cecropin-based defence system of insects, is secreted into the larval body during parasitism of the greater wax moth by the Heterorhabditis bacteriophora/Photorhabdus luminescens complex and by phase 1 of P. luminescens. The proteolytic digestion of insect inducible cecropin-like immune molecules was demonstrated by the disappearance of the Galleria mellonella cecropins and purified Hyalophora cecropin B peptide PAGE bands upon exposure to infected extracts, and a similar abrogation of antibacterial activity using an agar diffusion assay. Proteolytic activity of infected extracts produced by nematode/bacterial complex and phase 1 variant of P. luminescens was shown to be correlated with cecropin-inhibitory activity, suggesting that this anti-cecropin agent may be responsible for the ability of bacteria to establish infection and the insecticidal nature of H. bacteriophora. Antibacterial activity of Galleria lysozyme and that of chicken egg-white lysozyme to which P. luminescens is insensitive, was unaffected by H. bacteriophora proteinase.

Abstract
The interest of marine invertebrates as food resources provides a major interest to study molluscan immunity for better understanding of the host response to pathogens. Molluscs possess a natural immunity formed by anatomical and chemical protective barriers that prevent damage of the underlying tissues, body fluid losses and the infections of pathogenic microorganisms and parasites. The main physical barrier is shell and mucus which cover the soft body of molluscs. The integrity of body coverings is supported by blood clotting and wound healing. The internal defense mechanisms of molluscs involve such cellular reactions as: phagocytosis, nodule formation, encapsulation, pearl formation, atrophy, necrosis and tissue liquefaction. Granular hemocytes are the most numerous cell type of molluscan blood active in cellular defenses. Invaders small in size are eliminated by phagocytosis in which participate lectins and products of prophenyloxidase system activation. Numerous and large intruders are eliminated by nodule formation or encapsulation, either cellular or humoral. Humoral components of molluscan immunity are formed by lysozyme activity, lectins and the phenyloxidase system. Up to now the role of mercenenes, paolins, acute phase reactants, alpha 2-macroglobulins and multifunctional binding proteins with anti-protease activity is not well clarified yet. Research prospects on the field of molluscan immunology should essentially be devoted to study cellular defense functions and humoral effectors to select pathogen-resistant molluscs. This aim could also be achieved by the identification and characterization of immune genes which are candidates for molluscs genetic transformation.

Abstract
The knowledge of the immunity in annelids started with the use of earthworms as biomarkers indicating changes caused by environmental pollution. Defence strategies effectively protect earthworms against bacterial infections and parasitic invasion. A natural immunity formed by anatomical and chemical protective barriers prevents damage of the underlying tissues, body fluid losses, and microbial infections of the body cavity. The internal defence mechanisms of annelids involve phagocytosis, nodule formation and encapsulation, blood coagulation and wound repair, and antibacterial immune proteins. The antibacterial activity of coelomic fluid associated with lysozyme-like substances and inducible humoral molecules support haemocytic reactions in the annelid defence system.

Abstract
Bilateral uterine artery embolisation was performed to treat eight women with symptomatic large fibroids requiring treatment. Uterine volume was quantitatively assessed by magnetic resonance imaging. Both uterine arteries were occluded effectively in all women, and the procedure was well tolerated, with a 24-36 hour admission for pain relief. The level of pain experienced was variable, but well controlled. Some women experienced intermittent vaginal discharge and pain following the procedure. Improvement of symptoms occurred in six of the seven women and the eighth woman conceived. There were no significant complications. At three months four women had a uterine volume of < 350 cm3. Embolisation appears to be a good alternative to surgery, but longer follow up is required to evaluate the long term effects and to determine those patients for whom the procedure is suitable.

Abstract
Insect-pathogenic strains of Pseudomonas aeruginosa produce specific proteinase which selectively degrades the cecropin-based defence system of insects. This was demonstrated by the disappearance of the Galleria cecropin and purified Hyalophora cecropin B peptide PAGE bands, but not the lysozyme band, upon exposure to infected extracts and a similar abrogation of antibacterial activity using an agar diffusion assay. In addition, the proteolytic activity of infected extracts produced by high and low virulence Pseudomonas strains was shown to be correlated with cecropin-inhibitory activity. This indicated that the bacterial proteinase was responsible for the ability of bacteria to establish infections and strain virulence.

Abstract
The insect immune system reacts against invading microorganisms and parasites with the recruitment of haemocytes and with humoral response. Cellular immune reactions involve phagocytosis, nodule formation and encapsulation by different types of haemocytes whereas insect cell-free antibacterial immunity depends on the production of a number of peptides and proteins, among which lysozyme, cecropins and attacins represent the major group of immune proteins. Polydnaviruses from certain hymenopterous parasitoids interfere with both host immunity and host development. These immunosuppressive viruses exhibit an intimate genetic relationship with the parasitoid since viral sequences are integrated within the parasitoid chromosomal DNA. The viral genes expression in parasitized host induces immunosuppression and alters development of the host insect. The parasitoids developing in the host body cavity knock out the insect immune system, inducing a decline in cellular and humoral components of the immune system so that parasitoid eggs are not recognized as foreign and thereby are not encapsulated. Polydnaviruses carrying parasitoids escape the host immune response and may develop within the insect host whereas other invaders are normally destroyed by defense factors of insect haemolymph.

Abstract
Based on the ability of bacterial associates of entomopathogenic nematodes to produce antibiotic compounds on artificial media, it has been commonly accepted that Xenorhabdus sp. and Photorhabdus sp. inhibit a wide range of invading microorganisms in insects infected with Steinernema spp. or Heterorhabditis spp. Therefore, the question of whether antibiotic compounds produced by the primary form of bacterial symbionts associated mutualistically with S. carpocapsae and H. bacteriophora explain why insect carcasses do not putrefy but provide nutritional requirements for insect parasitic rhabditoid nematodes to complete their life-cycle was examined. Laboratory bioassays of anti-bacterial activity on nutrient agar and during parasitism in larvae of Galleria mellonella have confirmed earlier observations that in virto colonies of the primary form of X. nematophilus and P. luminescens produced agar-diffusible antibiotic compounds of a broad spectrum of anti-bacterial activity; their role in parasitism seems doubtful, however. This hypothesis is supported by a low antibiotic potency of a limited spectrum of anti-bacterial activity throughout the life-cycle of the parasites, principally in Galleria infected with S. carpocapsae. Since the lack of putrefaction cannot be explained simply by antibiotic inhibition of contaminating bacterial microflora, other competition mechanisms must be operating in parasitized insects. I postulated that a rapid and massive colonization of the insect body by nematophilic bacteria creates unfavorable conditions for the growth and multiplication of bacterial (proteolytic) contaminators making the insect carcass decay-resistant. In the case of H. bacteriophora, low antibiotic activity at an early stage of parasitism could support the colonization by P. luminescens of the host.

Abstract
1. Pupae of Galleria mellonella and Pieris brassicae given an injection with live, non-pathogenic Enterobacter cloacae or abiotic foreign molecules induce an acquired immunity that corresponds with the synthesis of haemolymph proteins of antibacterial activity. 2. This humoral defensive response which persists for several days, differs quantitatively between insect species and between the inducers used, although very different foreign bodies induced the same immune proteins in both lepidopteran insects. 3. A stronger and longer lasting response was consistently noticed in pupae immunized with non-pathogenic bacterium than after sterile nutrient broth injections. 4. A demonstrably elevated activity of haemolymph lysozyme and trace activity of cecropins found in pupae of Galleria treated with saline W, a salt solution physiological to moths, disappear soon after 36 hr from injection. 5. In P. brassicae, however, sterile insect Ringer can give a varying, if present at all, immune response. 6. A mechanical injury (sterile wounding of insect body) can occasionally induce a similar but much weaker response. 7. The antibacterial activity was drastically reduced in Pieris or completely depressed in most pupae of Galleria when actinomycin D or cycloheximide was given at an early time post-immunization with E. cloacae. 8. It is concluded that the de novo synthesis of ribonucleic acid and immune proteins is required for expression of antibacterial activity in pupal haemolymphs. 9.

Abstract
The pleiotropic cytokine TNF has been implicated in the regulation of many immune and inflammatory responses in vivo, and in addition exerts a wide range of effects on target cells in vitro. However, although two cell surface receptors for TNF have been identified, and their cDNAs cloned, the amino acid residues necessary for the biological activity of TNF have not been characterized. We have therefore constructed derivatives of TNF termed 'muteins', in which the first 3 to 7 amino acids of native TNF-alpha have been replaced, using synthetic cDNA expressed in E. coli. In the present study we compare the effects of native TNF-alpha and muteins III, IV, V and VI in several different in vitro systems and in one in vivo model. We observed binding to the p75 TNF receptor on Jijoye Burkitt lymphoma cells with native TNF-alpha and mutein III alone, whereas the p55 TNF receptor on the human epithelioid carcinoma cell line HeLa bound TNF-alpha, mutein III and mutein V. Muteins IV and VI failed to recognize either TNF receptor. WEHI 164 fibrosarcoma cells were killed by muteins III, V and VI. Human umbilical vein endothelial cells responded to native TNF-alpha and to muteins III, IV and V, but not to mutein VI, by increasing the surface expression of ICAM-1 antigen and secretion of the cytokines GM-CSF and IL-6. All four compounds were pro-inflammatory in a mouse in vivo model. The results presented in this report confirm that N-terminal amino acids are critical for both receptor binding and biological activity of TNF-alpha.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The use of continuous thoracic epidural anaesthesia allows several oncological and reconstructive operations of the breast to be performed on an outpatient basis. The method is easy and safe in the hands of an experienced anaesthetist, and the recovery is immediate. The potential side effects (transient haemodynamic changes) may result from the sympathetic blockade and can be easily controlled during the operation. The method is not advocated in cases in which substantial blood loss is anticipated.
