Abstract
Key Clinical Message HHV8- and EBV-negative primary effusion lymphoma is an extremely rare neoplasm involving body cavities without detectable tumor mass. It usually presents in elderly patients without known immunodeficiency. Compared to primary effusion lymphoma, it has a better prognosis. Primary effusion lymphoma (PEL) is a rare non-Hodgkin lymphoma confined exclusively to body cavities without detectable tumor masses. The term PEL-like is an entity similar to PEL in clinical presentation but without relation to human herpesvirus 8 (HHV8). We report a case of HHV8- and EBV-negative primary effusion-based lymphoma.

Abstract
The frequency of aggressive subtypes of B-cell non-Hodgkin lymphoma (B-NHL), such as high-grade B-cell lymphomas (HGBL) with MYC and BCL2 and/or BCL6 rearrangement (HGBL-DH/TH) or Burkitt-like lymphoma (BL) with 11q aberration, is not well known in the HIV setting. We aimed to characterise HIV-associated aggressive B-NHL according to the 2017 WHO criteria, and to identify genotypic and phenotypic features with prognostic impact. Seventy-five HIV-associated aggressive B-NHL were studied by immunohistochemistry (CD10, BCL2, BCL6, MUM1, MYC, and CD30), EBV-encoded RNAs (EBERs), and fluorescence in situ hybridisation (FISH) to evaluate the status of the MYC, BCL2, and BCL6 genes and chromosome 11q. The 2017 WHO classification criteria and the Hans algorithm, for the cell-of-origin classification of diffuse large B-cell lymphomas (DLBCL), were applied. In DLBCL cases, the frequencies of MYC and BCL6 rearrangements (14.9 and 27.7%, respectively) were similar to those described in HIV-negative patients, but BCL2 rearrangements were infrequent (4.3%). MYC expression was identified in 23.4% of DLBCL cases, and coexpression of MYC and BCL2 in 13.0%, which was associated with a worse prognosis. As for BL cases, the expression of MUM1 (30.4%) conferred a worse prognosis. Finally, the prevalence of HGBL-DH/TH and BL-like with 11q aberration are reported in the HIV setting. The phenotypic and genotypic characteristics of HIV-associated aggressive B-NHL are similar to those of the general population, except for the low frequency of BCL2 rearrangements in DLBCL. MYC and BCL2 coexpression in DLBCL, and MUM-1 expression in BL, have a negative prognostic impact on HIV-infected individuals.

Abstract
The impact of measurable residual disease (MRD) on cord blood transplantation (CBT) outcomes has remained debated. To address this issue, we assessed the impact of measurable MRD at CBT on outcomes in large cohort of patients with acute leukemia. Inclusion criteria included adult patients with acute myeloid (AML) or acute lymphoblastic leukemia (ALL), CBT as first allo-HCT in first or second complete remission (CR) at transplantation, and known MRD status at the time of CBT. Data from 506 patients were included in the analysis. Among them, 317 patients had AML and 189 had ALL. Positive MRD was reported in 169 (33%) patients while the remaining 337 patients were MRD negative at CBT. At 2 years, relapse incidence was 18% in patients with MRD negativity vs 33% in those with MRD positivity at transplantation (P < .001). Two-year leukemia-free survival (LFS) and overall survival (OS) were 57% and 60%, respectively, in MRD negative patients, vs 38% (P < .001) and 48% (P = .004), respectively, in those with MRD positivity. There was no interaction between the impact of MRD on OS and LFS and diagnosis (ie, ALL vs AML), single or double CBT, and reduced-intensity or myeloablative conditioning. On multivariate analysis, MRD positivity was associated with a higher risk of relapse (HR = 1.8, P = .003), comparable non-relapse mortality (P = .44), worse LFS (HR = 1.4, P = .008) and a trend towards worse OS (HR = 1.3, P = .065). In conclusion, these data suggest that novel strategies that are aiming to achieve MRD negativity at CBT are needed for leukemic patients with positive MRD pre-CBT.

Abstract
Recurrent deletions of the CDKN2A/ARF/CDKN2B genes encoded at chromosome 9p21 have been described in both pediatric and adult acute lymphoblastic leukemia (ALL), but their prognostic value remains controversial, with limited data on adult T-ALL. Here, we investigated the presence of homozygous and heterozygous deletions of the CDKN2A/ARF and CDKN2B genes in 64 adult T-ALL patients enrolled in two consecutive trials from the Spanish PETHEMA group. Alterations in CDKN2A/ARF/CDKN2B were detected in 35/64 patients (55%). Most of them consisted of 9p21 losses involving homozygous deletions of the CDKNA/ARF gene (26/64), as confirmed by single nucleotide polymorphism (SNP) arrays and interphase fluorescence in situ hybridization (iFISH). Deletions involving the CDKN2A/ARF/CDKN2B locus correlated with a higher frequency of cortical T cell phenotype and a better clearance of minimal residual disease (MRD) after induction therapy. Moreover, the combination of an altered copy-number-value (CNV) involving the CDKN2A/ARF/CDKN2B gene locus and undetectable MRD (≤ 0.01%) values allowed the identification of a subset of T-ALL with better overall survival in the absence of hematopoietic stem cell transplantation.

Abstract
The test-retest reliability of the Spanish Diagnostic Interview Schedule for Children (DISC-IV) is presented. This version was developed in Puerto Rico in consultation with an international bilingual committee, sponsored by NIMH. The sample (N = 146) consisted of children recruited from outpatient mental health clinics and a drug residential treatment facility. Two different pairs of nonclinicians administered the DISC twice to the parent and child respondents. Results indicated fair to moderate agreement for parent reports on most diagnoses. Relatively similar agreement levels were observed for last month and last year time frames. Surprisingly, the inclusion of impairment as a criterion for diagnosis did not substantially change the pattern of results for specific disorders. Parents were more reliable when reporting on diagnoses of younger (4-10) than older children. Children 11-17 years old were reliable informants on disruptive and substance abuse/dependence disorders, but unreliable for anxiety and depressive disorders. Hence, parents were more reliable when reporting about anxiety and depressive disorders whereas children were more reliable than their parents when reporting about disruptive and substance disorders.

Abstract
In previous studies it has been shown that neural cells undergoing programmed cell death display strongly positive cytoplasmic immunoreactivity to polyclonal antibodies directed against a c-Jun N-terminal peptide. It was later found that c-Jun-like immunoreactivity in apoptosis was due to cross-reactivity with proteins other than c-JUN: We have analysed the biochemical counterpart of this property in neuroblastoma cell lines treated to induce apoptosis. Using the c-Jun/sc-45 antibody, several bands with apparent molecular masses distinct from c-Jun were detected in extracts in parallel with both the degree of apoptosis and the appearance of the cytoplasmic signal after immunostaining. c-Jun/sc-45 immunostaining was prevented by caspase inhibitors and did not require de novo protein synthesis. One of the antigens recognized by the c-Jun/sc-45 antibody was identified as seryl-tRNA synthetase. We provide evidence that seryl-tRNA synthetase is a substrate of caspase-3 in vitro and that the digested form turns highly immunoreactive towards the antibody. A carboxy-terminus epitope of the protein that constitutes a consensus site for caspase-3 is involved in c-Jun/sc-45 recognition. This epitope shares some amino acids with the peptide used as the immunogen and this could explain the cross-reactivity observed. In conclusion, we demonstrate here that cytoplasmic c-Jun/sc-45-like immunoreactivity specific to apoptosis is due to post-translational changes which occur in seryl-tRNA synthetase and probably also in other proteins as a consequence of caspase mediated proteolysis.

Abstract
Motoneurons respond to peripheral nerve transection by either regenerative or degenerative events depending on their state of maturation. Since the expression of c-Jun has been involved in the early signalling of the regenerative process that follows nerve transection in adults, we have investigated c-Jun on rat neonatal axotomized motoneurons during the period in which neuronal death is induced. Changes in levels of c-Jun protein and its mRNA were determined by means of quantitative immunocytochemistry and in situ hybridization. Three hours after nerve transection performed on postnatal day (P)3, c-Jun protein and mRNA is induced in axotomized spinal cord motoneurons, and high levels were reached between 1 and 10 days after. This response is associated with a detectable c-Jun activation by phosphorylation on serine 63. No changes were found in the levels of activating transcription factor -2. Most of dying motoneurons were not labelled by either a specific c-Jun antibody or a c-jun mRNA probe. However, dying motoneurons were specifically stained by a polyclonal anti c-Jun antibody, indicating that some c-Jun antibodies react with unknown epitopes, probably distinct from c-Jun p39, that are specifically associated with apoptosis.

Abstract
I(2)-imidazoline receptors are mainly expressed on glial cells in the rat brain. This study was designed to test the effect of treatment with the I(2)-imidazoline selective receptor ligand LSL 60101 [2-(2-benzofuranyl)imidazole] on the morphology of astrocytes in the neonate and adult rat brain, and to explore the putative neuroprotective effects of this glial response. Short-term (3 days) or chronic (7-10 days) treatment with LSL 60101 (1 mg kg(-1), i.p. every 12 h) enhanced the area covered by astroglial cells in sections of facial motor nucleus from neonate rats processed for glial fibrillary acidic protein (GFAP) immunostaining. Facial motoneurons surrounded by positive glial cell processes were frequently observed in sections of LSL 60101-treated rats. A similar glial response was observed in the parietal cortex of adult rats after chronic (10 days) treatment with LSL 60101 (10 mg kg(-1), i.p. every 12 h). Western-blot detection of the specific astroglial glutamate transporter GLT-1, indicated increased immunoreactivity after LSL 60101 treatment in the pons of neonate and in the parietoccipital cortex of adult rats. In the facial motor nucleus of neonate rats, the glial response after LSL 60101 treatment was associated to a redistribution of the immunofluorescence of the basic fibroblast growth factor (FGF-2) from the perinuclear area of motoneurons to cover most of their cytoplasm, suggesting a translocation of this mitogenic and neurotrophic factor towards secretion pathways. The neuroprotective potential of the above effects of LSL 60101 treatment was tested after neonatal axotomy of facial motor nucleus. Treatment with LSL 60101 (1 mg kg(-1), i.p. every 12 h from day 0 to day 10 after birth) significantly reduced (38%) motoneuron death rate 7 days after facial nerve axotomy performed on day 3 after birth. It is concluded that treatment with the I(2)-imidazoline selective receptor ligand LSL 60101 provokes morphological/biochemical changes in astroglia that are neuroprotective after neonatal axotomy.

Abstract
Acute administration of a single dose of NMDA on embryonic day (E) 7 or later induces a marked excitotoxic injury in the chick spinal cord, including massive necrotic motoneuron (MN) death. When the same treatment was performed before E7, little, if any, excitotoxic response was observed. Chronic treatment with NMDA starting on E5 prevents the excitotoxic response produced by a later "acute" administration of NMDA. Additionally, chronic NMDA treatment also prevents the later excitotoxic injury induced by non-NMDA glutamate receptor agonists, such as kainate or AMPA. Chronic NMDA treatment also reduces normal MN death when treatment is maintained during the period of naturally occurring programmed cell death (PCD) of MNs and rescues MNs from PCD induced by early peripheral target deprivation. The trophic action of chronic NMDA treatment appears to involve a downregulation of glutamate receptors as shown by both a reduction in the obligatory NR1 subunit protein of the NMDA receptor and a decrease in the kainate-induced Co(2+) uptake in MNs. Both tolerance to excitotoxicity and trophic effects of chronic NMDA treatment are prevented by the NMDA receptor antagonist MK-801. Additionally, administration of MK-801 alone results in an increase in MN PCD. These data indicate for the first time that early activation of NMDA receptors in developing avian MNs in vivo has a trophic, survival-promoting effect, inhibiting PCD by a target-independent mechanism that involves NMDA receptor downregulation.

Abstract
We have examined c-Jun protein expression by immunocytochemistry in normal and pathologically induced cell death by focusing primarily on the developing neuromuscular system of the chick embryo. Several commercially available antibodies against c-Jun were used in combination with the TUNEL technique or propidium iodide staining for detection of cells undergoing programmed cell death (PCD). Among these, a rabbit polyclonal antibody raised against the amino acids 91-105 mapping to the amino terminal domain of mouse c-Jun p39 (c-Jun/sc45) transiently immunostained the cytoplasm of dying spinal cord motoneurons at a time coincident with naturally occurring motoneuron death. Late apoptotic bodies were devoid of c-Jun/sc45 immunoreactivity. A monoclonal antibody directed against a region corresponding to the amino acids 26-175 of c-Jun p39 (c-Jun/mAB) did not specifically immunostain dying neurons, but, rather, showed nuclear immunolabeling in almost all healthy motoneurons. Experimentally induced programmed death of motoneurons by means of early limb bud ablation, axotomy, or in ovo injection of the neurotoxin beta-bungarotoxin increased the number of dying cells showing positive c-Jun/sc45 immunoreactivity. Immunoelectron microscopy with c-Jun/sc45 antibody showed that the signal was present in the cytoplasm without a specific association with organelles, and was also present in large lysosome-like dense bodies inside neuritic profiles. Similar findings were obtained in different types of cells undergoing normal or experimentally induced PCD. These include dorsal root ganglion neurons, Schwann cells, muscle cells, neural tube and neural crest cells during the earliest stages of spinal cord development, and interdigital mesenchymal cells of hindlimbs. In all these cases, cells showed morphological and histochemical characteristics of apoptotic-like PCD. By contrast, motoneurons undergoing necrotic cell death induced by the excitotoxin N-methyl-D-aspartate did not show detectable c-Jun/sc45 immunoreactivity, although they displayed an increase in nuclear c-Jun/mAB immunostaining. In Western blot analysis of spinal cord extracts, c-Jun/sc45 antibody weakly detected a 39-kD band, corresponding to c-Jun, and more strongly detected two additional bands of 66 and 45 kD which followed developmental changes coincident with naturally occurring or experimentally stimulated apoptotic motoneuron death. By contrast, c-Jun/mAB only recognized a single p39 band as expected for c-Jun, and did not display changes associated with neuronal apoptosis. From these data, we conclude that the c-Jun/sc45 antibody recognizes apoptosis-related proteins associated with the early stages of morphological PCD in a variety of neuronal and non-neuronal cells, and that c-Jun/sc45 is a reliable marker for a variety of developing cells undergoing programmed cell death.

Abstract
The distribution of nitric oxide synthase on peripheral motor system was studied using a specific antibody against the neuronal isoform of nitric oxide synthase (nNOS). The immunoreactivity for nNOS was detected on the sarcolemmal surface of muscle cells, in intramuscular axons and in neuromuscular synapses. At the neuromuscular junctions, ultrastructural immunolabeling demonstrated that nNOS immunoreactivity was localized mainly into the presynaptic nerve terminals as well as adjacent postsynaptic muscle membrane. Similar immunostaining pattern was present in frog muscles and Torpedo electric organs. After chronic muscle denervation, nNOS immunoreactity at endplate level decreased during the first week but it was upregulated after 30 days of denervation. In denervated endplates, nNOS immunoreactivity was localized in the terminal Schwann cells covering the degenerated neuromuscular junctions whereas nNOS was not detected in Schwann cells under normal conditions. In Torpedo synaptosomes, acetylcholine (ACh) release elicited by potassium depolarization was inhibited by NO donors such as sodium nitroprusside. In contrast, application of inhibitors of NOS activity, aminoguanidine (AMG) and N(omega)-Nitro-L-arginine methyl esther (L-NAME) increased acetylcholine release. These results indicate that nNOS is present at the motor nerve terminals in a variety of vertebrates and that it may be involved in the physiological modulation of ACh release and in the regulation of muscle response to nerve injury.

Abstract
We have previously reported that stimulation of astrocyte cultures by particular agonists and calcium ionophores induces cyclic GMP formation through activation of a constitutive nitric oxide synthase (NOS) and that astrocytes from cerebellum show the largest response. In the present work we have used rat cerebellar astrocyteenriched primary cultures to identify and characterise the isoform of NOS expressed in these cells. The specific NOS activity in astrocyte homogenates, determined by conversion of [3H]arginine to [3H]citrulline, was ten times lower than in homogenates from cerebellar granule neurons. Upon centrifugation at 100,000 g, the astroglial activity was recovered in the supernatant, whereas in neurons around 30% of the activity remained particulate. The cytosolic NOS activities of both astrocytes and granule neurons displayed the same Km for L-arginine, dependency of calcium, and sensitivity to NOS inhibitors. Expression of NOS-I in astrocyte cytosolic fractions was revealed by Western blot with a specific polyclonal antiserum against recombinant NOS-I. Double immunofluorescence labelling using anti-glial fibrillary acidic protein (GFAP) and anti-NOS-I antibodies revealed that a minor population of the GFAP-positive cells, usually in clusters, presented a strong NOS-I immunostaining that was predominantly located around the nuclei and had a granular appearance, indicating association with the endoplasmic reticulum-Golgi system. Astrocytes of stellate morphology also showed immunoreactivity in the processes. Similar staining was observed with the avidin-biotin-peroxidase complex using different anti-NOS-I antisera. With this method the majority of cells showed a weak NOS-I immunoreactivity around the nuclei and cytosol. A similar pattern was observed with the NADPH-diaphorase reaction. These results demonstrate that the NOS-I expressed in astrocytes presents the same biochemical characteristics as the predominant neuronal isoform but may differ in intracellular location.

Abstract
The effects of several imidazoli(di)ne compounds on the binding of the non-competitive NMDA receptor antagonist [3H](+)-MK-801 (dizocilpine) to rat brain membranes were studied. These compounds fully inhibit radioligand binding with potencies in the micromolar range. The obtained profile of drug affinity correlated well with the potency of the same compounds promoting insulin release by blocking ATP-sensitive K+ channels in the rat insulinoma cell line RIN-5AH. It is suggested that imidazoli(di)ne compounds interact with cation channels sharing a common phencyclidine binding site (e.g. NMDA receptors, K+ channels and nicotinic acetylcholine receptors) and that this could be the basis of some biological effects of imidazoli(di)nes.

Abstract
Expression of the different members of transcription factors Fos and Jun was examined in the developing rat brain. Constitutive expression of c-Fos, Fos-related antigens, Jun B and Jun D, as revealed with immunohistochemistry, is higher and more widely distributed in the developing rat brain than in the adult. Selective strong c-Jun expression is observed in the cytoplasm and nuclei of apoptotic cells during the whole process of naturally occurring (programmed) cell death. Cells expressing strong c-Jun immunoreactivity are undetermined cells, neurons and astrocytes. Selective c-Jun expression is also observed following ionizing radiation in rats aged 3 days. Induction of c-jun mRNA, as revealed with in situ hybridization, occurs between 5 and 15 min following gamma-irradiation. Strong c-Jun protein expression appears at 2 h, peaks at 6 h and decreases thereafter to reach normal levels 48 h after gamma-ray exposure. Strong c-Jun protein expression is coincidental with endonuclease activation, as revealed with the method of in situ labelling of nuclear DNA fragmentation, and is restricted to apoptotic cells. Cycloheximide injection at the time of irradiation blocks c-Jun expression, indicating that c-Jun immunoreactivity is attributable to de novo protein synthesis. These observations demonstrate in vivo selective strong c-Jun expression associated with programmed cell death and ionizing radiation-induced apoptosis in the developing rat brain.

Abstract
The aim of this study was to examine whether changes in rat motoneuronal calcitonin gene-related peptide (CGRP) can be correlated with axonal growth and plasticity of neuromuscular synapses. Nerve terminal outgrowth was induced by local paralysis with botulinum toxin. Normal adult soleus and tibialis anterior did not show detectable CGRP content at the motor endplates. Following botulinum toxin injection there was a progressive, transient and bimodal increase in CGRP in both motoneuron cell bodies which innervated poisoned muscles and their motor endplates. CGRP content was moderately increased 1 day after paralysis and, after an initial decline, reached a peak 20 days after injection. This was followed by a gradual decrease and a return to normal levels at the 200th day. CGRP changes in intoxicated endplates were less evident in the tibialis anterior than in the soleus muscle. The CGRP content in motoneurons was positively correlated with the degree of intramuscular nerve sprouting found by silver staining. In situ hybridization revealed an increase in CGRP mRNA in spinal cord motoneurons 20 days after toxin administration. We conclude that motoneurons regulate their CGRP in situations in which peripheral synapse remodelling and plasticity occur.

Abstract
In the present work we study the functional role of muscle cell extracellular matrix components in axonal guidance during synaptic regeneration. We focused on components recognized by the N-acetylglucosamine-specific lectin called wheat germ agglutinin (WGA) that has been shown to bind to the muscle cell extracellular matrix. We have used a cryoculture bioassay which is based on the ability of chick ciliary ganglion neurons to grow on rat skeletal muscle cryostat sections [Covault, J., et al., J. Neurosci., 105 (1987) 2479-2488.]. In control cultures neurites extended upon the muscle sections closely associated to the muscle cell surface. Masking WGA lectin receptors on the muscle cell surface perturbed the behavior of neurites. On WGA-treated sections, most of the neurites extended indiscriminately on intercellular and intracellular regions. These results indicate that N-acetylglucosamine-bearing molecules on muscle cell surfaces may play functional roles in the guidance of neurites through the extracellular matrix.

Abstract
Motoneuron cell death was analysed in the rat facial motor nucleus after neonatal facial nerve transection. In situ DNA fragmentation labelling showed that axotomized motoneurons die by an apoptotic mechanism. In order to investigate the existence of excitotoxic mechanisms in this type of neuronal death, rats were treated with several agents known to possess neuroprotective action through a variety of mechanisms. The Na+ channel inhibitor lamotrigine and the antagonist for the N-methyl-D-aspartate-type glutamate receptor, dizocilpine maleate (MK-801) were found to be able to rescue motoneurons from cell death induced by axotomy. The nitric oxide synthase inhibitor N omega-nitro-L-arginine methyl ester was also able to protect motoneurons from death, but to a lesser extent. The distribution of constitutive and inducible isoforms of nitric oxide synthase was investigated by immunocytochemistry in the facial motor nucleus. No changes were detected in constitutive nitric oxide synthase immunoreactivity in the facial motor nucleus after axotomy. However, in the axotomized facial motor nucleus, inducible nitric oxide synthase showed a positive immunolabelling specifically located in activated astrocytes, but not in microglia. Nitric oxide derived from activated astrocytes may have a role in promoting excitotoxic mechanisms in axotomized motoneurons. We conclude that excitotoxic mechanisms involving apoptotic cell death are present when immature motoneurons die as a consequence of target disconnection.

Abstract
The purpose of the work reported here is to identify molecular components of the synaptic basal lamina of skeletal muscle fibres which allow recognition of original synaptic sites by regenerating motor axons. We focused on s-laminin and components recognized by the lectin Dolichos biflorus agglutinin previously shown to be specifically located at the synaptic basal lamina. We used a cryoculture bioassay in which chick ciliary ganglion neurons grow on rat skeletal muscle cryostat sections. In control cultures, neurites extended over the muscle sections in close association with the muscle cell surface. It was observed that most of the neurites that extended towards the endplate zone and reached an area of 40 microns around the neuromuscular junction ceased to grow when they contacted the synaptic site. Masking either lectin receptors or some s-laminin molecule epitopes prior to the culture of neurons alters the behaviour of growing neurites. On sections treated either with Dolichos biflorus agglutinin or anti s-laminin monoclonal antibodies (D5 and C4) most of the neurites did not stop their growth at the synaptic regions. Moreover, treating muscle sections with Dolichos biflorus agglutinin removed the gradient of substratum affinity around the endplate. These results indicate that the s-laminin and Dolichos biflorus agglutinin receptors present on muscle cell surfaces may play a functional role in the interaction of growing neurites with original synaptic sites in the process of neuromuscular regeneration.

Abstract
The lectins DBA, WGA, SBA, Con A, GS-1, LFA and PNA were used to characterize the carbohydrate domains of the rat neuromuscular junction. DBA stained only the synaptic domains of muscle surface. All other lectins stained the whole muscle surface but the intensity of staining was stronger at the synaptic regions. However, when sections were treated with several digestive agents prior to lectin application, the lectin staining pattern changed dramatically. Collagenase-sensitive GlcNac, Mannose, Sialic acid, and GalNac-containing glycoconjugates associated with synaptic regions but not present extrasynaptically were revealed after chemical treatment. On the basis of these modifications it is proposed that, apart from the synapse-specific GalNac-containing glycoconjugate already described elsewhere, new carbohydrate-containing compounds are evidenced. These results provide a new insight into regional specialization of the extracellular matrix associated with the neuromuscular junctions and indicates that pretreatment with various agents, not necessary digestive substances, may alter molecular properties of muscle membrane and uncover previously unknown binding sites.

Abstract
The experience of 22 Hodgkin's disease (HD) patients with human immunodeficiency virus type I (HIV) antibodies, collected from a cooperative study of six hospitals during 1984-1989 is presented. Young men (average age, 27.6 years) with a high incidence of intravenous drug abuse (86%) were found. The status of the HIV infection at diagnosis of HD was: four patients, acquired immune deficiency syndrome (AIDS); eight patients, persistent generalized lymphadenopathy (PGL); and ten patients, asymptomatic. The natural history of HD was unusual, with a high incidence of B symptoms (81%), advanced Stages III to IV (90%), bone marrow invasion (50%), cytopenias before treatment (45%), opportunistic infections (68%), and aggressive histologies. A decreased response to chemotherapy with poor marrow tolerance and a significant decrease in survival, 18 months, was observed. The AIDS and cytopenias pretreatment were associated with a shorter statistically significant survival, which defines the importance of immunodeficiency in HD prognosis. Complete remission after treatment was a factor that contributed to a longer statistically significant survival. The PGL or asymptomatic patients survived longer but also had a poor course, and five of them had AIDS criteria during evolution. A high incidence of HD in relation to non-Hodgkin's lymphoma (NHL) in patients with HIV infection in the six cooperating hospitals was found. Criteria for considering HD as an AIDS-associated lymphoproliferative disease in our environment are discussed.

Abstract
Soluble proteins from normal, adult denervated, and developing rat muscles were studied in order to identify common molecular species undergoing developmental regulation and nerve dependence. Significant increases in 66- and 30-kDa proteins were found as a consequence of 14 days of denervation. Subsequent reinnervation restores normal adult levels. During development, high levels of the 66-kDa protein were found in neonatal muscles but slowly decreased concomitant with the following postnatal maturation period; the adult levels were reached at Postnatal Day (P) 21. From the immunocytochemical studies it is deduced that both proteins were concentrated mainly at the end-plate region in adult normal muscle. Following denervation, the proteins were found distributed over the entire cell. For the 66-kDa protein, a similar pattern of extensive distribution was seen in immature muscle. Although no data for functional implications for these proteins are available at present, the properties described here make them of interest in understanding nerve-muscle interactions.

Abstract
A two-stage epidemiologic survey was carried out on a probability sample of the population aged 4 through 16 years in Puerto Rico. The survey used the Child Behavior Checklist as a screening instrument, and prevalence rates were estimated on the basis of clinical diagnoses and other measures provided by child psychiatrists during the second stage. Maladjustment was operationally defined through the use of combined measures, including DSM-III diagnosis and a scale of functional impairment. Data were provided on the demographic correlates of maladjustment and on the comorbidity of DSM-III diagnostic domains. The prevalence rates obtained vis-à-vis the availability of mental health services on the island reflected a major public health problem.

Abstract
The binding of agglutinin from Dolichus biflorus (DBA) and other lectins (Concanavalin A, agglutinin from wheat germ and lectin from Bandeiraea simplicifolia) to synaptic and extrasynaptic portions of the basal lamina of muscle fibers, was studied with histochemical methods. In rat muscle, DBA-binding is specifically detected at the basal lamina of neuromuscular junction. However, long-term (6 months) denervated end-plate in adult rat muscle failed to bind DBA. During normal development, synaptic DBA receptors appear later than acetylcholine receptors or acetylcholinesterase at the rat neuromuscular junction. Generalized DBA-binding to motor end-plates is first visualized in 3-day-old rats, but section of sciatic nerve in 1-day-old rats prevents the appearance of synaptic DBA-binding on the leg end-plates. It is suggested, therefore, that the synaptic DBA receptors could be related to the postnatal stabilization of rat neuromuscular synapses.

Abstract
The histochemical binding of seven fluoreceinated lectins was comparatively studied in muscular tissue from twenty three different animal species including mammalians, amphibians, avians and fishes. Special interest was taken in the exploration of the differential lectin-binding properties at the neuromuscular synapse. Binding to synaptic sites was demonstrated using lectins that recognizes N-acetylgalactosamine and among of them, Dolichus biflorus agglutinin (DBA), was the most specific. Nevertheless, DBA fails to stain endplates in the muscle from most of the avians and the fishes (including the Torpedo electric organ) indicating that a polymorphic distribution of glycoconjugates exist at the vertebrate neuromuscular junction. Other lectins such as Concanavalin A (ConA) or Wheat germ agglutinin (WGA), share a similar staining properties in all animals that we examined making an intense label over the complete muscle surface. Although the species-related polymorphism on lectin binding does not reveal a clear relationship with the evolutionary tree, they give an evidence on the chemical heterogeneity of molecules specifically concentrated at the neuromuscular junction.
