Abstract
Introduction Post-traumatic stress disorder (PTSD), is a Mental Health condition due to a traumatic experience. There are four types of Gender Violence in Latin America: physical, sexual, psychological or patrimonial violence, when it occurs between intimate partners it is called intimate partner violence (IPV). PTSD is highly associated with IPV. Objectives Determine the statistical index of IPV and PTSD in women and men in Guayaquil-Ecuador. Methods We carried out a descriptive cross-sectional study, the sample was collected at the Florida Prosecutor’s Office in Guayaquil-Ecuador by UCSG medical students in 2018. The sample was 239 individuals, 195 women, 44 men. Individuals were separated into groups by gender, marital status, children, age, habits and PTSD. We applied Beck test for Depression, Davidson and DSM-5 for PTSD. Results In this study we observe a male population suffering from IPV. Complaints of IPV 195 women (81.59%), 44 men (18.41%). PTSD positive 159 women (81.96%), men 35 (18.04%). More prevalent in age ranges 25-34. PTSD with children 147 (76%) and without children 47 (24%). Conclusions Factors such as being a woman, having children and younger ages are linked in this study as predisposing to suffer from IPV and PTSD. We highlight a male population that reports suffering from IPV despite the lack of support, especially in Latin America. It is worth mentioning that the final consequence in many cases is femicide and homicide. Although IPV is serious and frequent, Medical professionals still do not focus on IPV diagnosis, therefore affected individuals don t receive support. Disclosure No significant relationships.

Abstract
INTRODUCTION Hypofractionated whole breast irradiation (HWBI) is the current standard of treatment after breast conservative surgery (BCS). Intraoperative radiotherapy (IORT) must be associated to WBI in patients showing high-risk factors of local recurrence in the definitive pathology report. The aim of this trial was to evaluate, for the first time, the acute toxicity and cosmesis of HWBI after photon-IORT. MATERIALS AND METHODS Twenty-six luminal breast cancer patients treated by BCS and IORT(20 Gy) were included between February and December 2019, in this prospective trial, of adjuvant HWBI (40.5 Gy/2.67 Gy/15 fractions). Acute toxicity (CTCAEv5.0) and cosmesis (Harvard scale), were assessed 3 months after treatment. RESULTS All patients completed their treatment without interruptions. All cases were evaluable 3 months after treatment showing no toxicity ≥ G3 and excellent/good cosmesis assessment in 88% of the patients. CONCLUSION HWBI seems to have similar acute toxicity and cosmesis results than conventionally fractionated WBI in combination to photon-IORT after BCS.

Abstract
Hydrogen sulfide (H2 S) is a highly neurotoxic gas. Acute exposure can lead to neurological sequelae among survivors. A drug for treating neurological sequelae in survivors of acute H2 S intoxication is needed. Using a novel mouse model we evaluated the efficacy of cobinamide (Cob) for increasing survival of, and reducing neurological sequalae in, mice exposed to sublethal doses of H2 S. There were two objectives: (1) to determine the dose-response efficacy of Cob and (2) to determine the effective therapeutic time window of Cob. To explore objective 1, mice were injected intramuscularly with Cob at 0, 50, or 100 mg/kg at 2 min after H2 S exposure. For objective 2, mice were injected intramuscularly with 100 mg/kg Cob at 2, 15, and 30 min after H2 S exposure. For both objectives, mice were exposed to 765 ppm of H2 S gas. Cob significantly reduced H2 S-induced lethality in a dose-dependent manner (P < 0.05). Cob-treated mice exhibited significantly fewer seizures and knockdowns compared with the H2 S-exposed group. Cob also reversed H2 S-induced weight loss, behavioral deficits, neurochemical changes, cytochrome c oxidase enzyme inhibition, and neurodegeneration in a dose- and time-dependent manner (P < 0.01). Overall, these findings show that Cob increases survival and is neuroprotective in a mouse model of H2 S-induced neurological sequelae.

Abstract
Myotonic dystrophy type 1 is caused by expansion of a CTG trinucleotide repeat situated in the DMPK gene. Worldwide genetic studies suggest a single or limited number of mutational events cause the disease. However, distribution of CTG alleles and disease incidence varies among ethnicities. Due to the great ethnic diversity of the Mexican population, the present study was aimed at analyzing the impact of different lineages in shaping the CTG-repeat allelic distribution in the contemporary Mexican-Mestizo population as well as to shed light on the DM1 ancestral origin. Distribution of CTG-repeat alleles was similar among Mestizo and Amerindian subpopulations with (CTG)11-13 being the most frequent alleles in both groups, which implies that Mexican-Mestizo allelic distribution has been modeled by Amerindian ancestry. We diagnosed a relatively high number of cases, consistent with the high frequency of large-normal alleles found in Mexican subpopulations. Haplotype analysis using various polymorphic-markers in proximity to DMPK gene indicates that a single founder mutation originates myotonic dystrophy type 1 in Mexico; however, Y-STR haplogroups data and the presence of pre-mutated and large normal alleles in Amerindians support the hypothesis that both European and Amerindian ancestral chromosomes might have introduced the disease to the Mexican population, which was further disseminated through mestizaje.

Abstract
Although a variety of metabolic, toxic, psychiatric, and neurologic conditions can produce catatonic syndromes, it is less widely recognized that this state may be caused by epilepsy. We present the case of a woman with catatonic behavior, which she could not recall. She also exhibited olfactory, auditory and visual hallucinations. An EEG demonstrated diffuse abnormal electrical activity, mainly on left temporal and frontal areas. Treatment with anticonvulsant drugs yielded excellent response.

Abstract
ObjectivesTo determine the incidence of traumatic events in Ecuadorian women exposed to domestic violence and other complex social situations and their relationship with PTSD.MethodsWe applied a transversal descriptive study accomplished by the INEC (National Institute of Statistics and Census). The INEC recruited Ecuadorian women from 15 years old and more, the surveys were focused on this population. In total, 18,800 rural and urban housings were selected all over the country, 24 provinces. Date of the survey: November 16–December 15 of 2011. A, D and G were taken as references for guidelines following the criteria diagnosis of DSM V (Diagnostic and Statistical Manual of Mental Disorders) to determine a Traumatic Event.ResultsThe average age of the sample was 28 years old. The standard deviation was 21, ages: 15–25 years old: 14.265 (21.6%), 25–35 years old: 9.324 (14.1%), 35–45 years old: 8.132 (12.3%), 45–55 years old: 6.283 (9.5%), 55–65 years old: 4.302 (6.5%), > 65 years old: 23.745 (35.9%). Prevalence of the traumatic event (DSM-V) 4.6%. Women experienced any kind of violence 60.6%: 61.4% urban, 58.% rural. Types of abuse: psychological: 53.9%, physical: 38.0; sexual, patrimonial: 35.3%. Domestic violence 76.0% y other types of violence 24.0%.ConclusionDomestic violence rate is high, also, in this study, we determined that women face an important index of violence during their daily activities. Psychological abuse is the highest abuse, higher in the urban areas. These results based on acute traumatic events may predispose women to develop PTSD. The prevalence of traumatic events must be an alert to the Mental Health Organizations, not only in Ecuador but also in Latin American.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
We studied the interethnic variation of the MMP-9 microsatellite in the Mestizo and Amerindian populations using blood samples collected from 435 healthy unrelated individuals from the Central Valley of Mexico. DNA samples were genotyped using the -90 (CA)12-27 repeat near the MMP transcriptional start site using capillary electrophoresis. Our data were compared with those from African, Asian, and European populations (N = 729). Both Mestizo and Amerindian populations were in Hardy-Weinberg equilibrium (P ≥ 0.05). However, strong genetic heterogeneity was found within the Mestizo population (94%, P ≤ 0.0001), which exhibited the highest frequency of Amerindian, African, and European alleles. Likewise, Amerindians showed 6.7% variation among populations (P ≤ 0.0001), suggesting a genetic substructure potentially associated with linguistic affiliations. These findings were corroborated with principal component and population differentiation analyses, which showed relative proximity among the Mestizos and their historical parental populations: Asian (FST ≥ 0.05), European (FST ≥ 0.09), and African (FST ≥ 0.02). Nevertheless, important differences were found between Mestizo and Nahuas (P ≤ 0.0001), and between Mestizo and Me'Phaas (P ≤ 0.0001). These findings highlight the importance of determining local-specific patterns to establish the population variability of MMP-9 and other polymorphic markers. Validation of candidate markers is critical to identifying risk factors; however, this depends on knowledge of population genetic variation, which increases the possibility of finding true causative variants. We also show that dissimilar ethnic backgrounds might lead to spurious associations. Our study provides useful considerations for greater accuracy and robustness in future genetic association studies.

Abstract
BACKGROUND Limited published evidence shows oral desensitization to be a potential intervention option for cow's milk protein (CMPs) allergy. OBJECTIVE The aim of this study was to evaluate the safety and efficacy of oral desensitization in 2-year-old children with cow's milk allergy, as a treatment alternative to elimination diet. METHODS A total of 60 children aged 24-36 months with IgE-mediated allergy to CMPs were included in this multi-center study and were randomized into two groups. Thirty children (group A: treatment group) began oral desensitization immediately, whereas the remaining 30 (group B: control group) were kept on a milk-free diet and followed-up for 1 year. RESULTS After 1-year follow-up period, 90% of the children in group A had become completely tolerant vs. 23% of the children in group B. In group A, cow's milk skin reactivity and serum-specific IgE to milk and casein decreased significantly from the initial assessment, whereas group B showed no significant change after 1 year of follow-up. Twenty-four patients (80%) developed some reaction during the treatment period: 14 children developed moderate reaction (47%) and 10 mild reaction (33%). The most common manifestations were urticaria-angioedema, followed by cough. CONCLUSIONS AND CLINICAL RELEVANCE In this study, oral desensitization was found to be effective in a significant percentage of 2-year-old children with cow's milk allergy. Oral desensitization appears to be efficacious as an alternative to elimination diet in the treatment of 2-year-old children with cow's milk allergy. The side-effect profile appears acceptable but requires further study.

Abstract
PURPOSE This report describes the uncommon psychopathological state best known as folie à deux, or shared psychotic disorder, in a unique case in which the grandiose, religious delusions of a woman with uterine cancer are shared with her husband. OVERVIEW More than 50% of patients with cancer meet the criteria for diagnosis of major psychiatric disorders. Certainly, these disorders may occur as a result of the stress of the cancer diagnosis and treatment, but also because of a predisposition to psychiatric illness or a pre-existing psychiatric illness. In the medical setting, the phenomenon of folie à deux poses significant problems not only for the patient, but also for the involved family member, psychiatric consultant, and healthcare team. CLINICAL IMPLICATIONS In this case, the patient's delusional system had a grave impact on her ability to make rational healthcare decisions, for which she was deemed incompetent. The first choice for her healthcare surrogate, her husband, was so affected by his sharing of her psychotic condition that he could not fulfill this role. In assessing a suspected case of folie à deux, awareness of several issues--the point at which religious over-ideation becomes delusional, the spectrum of competency, informed consent, and treatment refusal--is important.

Abstract
The role of extracellular calcium on the induction of cyclic AMP production, N-acetyltransferase (NAT) activity and melatonin synthesis, induced by forskolin, was investigated in Syrian hamster pineal glands. Pineals were removed from hamsters killed either in the first half of the normal dark period or late in the dark period. Forskolin immediately increased NAT activity and melatonin levels only when the glands were collected late in the dark period, while in the first half of the dark phase, hamster pineals responded to forskolin with an increase of NAT activity and melatonin production only after 6 hr of incubation. The absence of calcium prevented the induction of melatonin synthesis by forskolin only when glands were collected early in the dark phase and incubated for 6 hr. In the second half of the normal dark period removal of calcium markedly decreased NAT activity and melatonin levels in glands incubated with forskolin for either 4 or 6 hr. However, the absence of extracellular calcium had no significant effect on the induction of cyclic AMP production by forskolin in pineals collected either early in the dark period or late in the dark phase. These data indicate that at least part of the action of extracellular calcium is indirect and that it affects steps in the induction of melatonin synthesis beyond the accumulation of cAMP.

Abstract
AIM To investigate whether cord blood levels of C-reactive protein, interleukin-1beta, interleukin-6, interleukin-8, tumour necrosis factor-alpha and the soluble receptor of interleukin-2, are useful markers in the diagnosis of early neonatal sepsis. DESIGN Umbilical cord blood samples were obtained at birth from 261 neonates, but 5 of these newborns were excluded from the study. Group I included 10 newborns that developed early neonatal sepsis with a positive blood culture; Group II included 11 newborns with non-infectious perinatal diseases; Group III, which served as the control group, included 10 randomly selected patients, matched for gestational age, among the 235 healthy newborn babies. RESULTS There were no differences among the three study groups in levels of C-reactive protein. interleukin-1beta, tumour necrosis factor-alpha and the soluble receptor of interleukin-2. Interleukin-6 was significantly elevated in Group I (360.4+/-157.8 pg/ml) and Group II (158.8+/-122.3 pg/ml), when compared with Group III (8.6+/-3.12 pg/ml) (p < 0.01), whereas interleukin-8 was significantly elevated in Group I (389.3+/-115.9 pg/ml) compared with Groups II (30.2+/-5.1 pg/ml) (p < 0.05) and III (33.9+/-8.6 pg/ml) (p < 0.05). A cut-off of 100.8 pg/ml for interleukin-6 obtained by the ROC (receiver operating characteristic) method gave a sensitivity of 50% and a specificity of 87%, and a cut-off of 111.7 pg/ml for interleukin-8 showed a sensitivity of 78% and a specificity of 91%. CONCLUSION While cord blood levels of interleukin-6 appear to be related to pathological conditions in the perinatal period (infectious and non-infectious), interleukin-8 seems to be a good predictor of early bacterial neonatal infection.

Abstract
We describe a patient with a neoplasm derived from the histiocytic-monocytic lineage associated with t(2;5) detected by FISH. The patient presented with bone marrow involvement, no organomegaly and subsequently developed a leukaemic picture. The clinical course was aggressive and the patient died four months from diagnosis. Cell morphology, immunophenotype (CD30-, EMA-, Lisozyme+, cy CD68+ and CD45+) and DNA analysis showing germ-line configuration of the Ig/TCR chain genes ruled out the diagnosis of anaplastic large cell lymphoma (ALCL). This unusual case ilustrates that t(2;5) is not exclusive for ALCL but may be found in a few cases of rare neoplasms derived from the histiocytic-monocytic cells.

Abstract
BACKGROUND We evaluate the prognostic value of stress echo and gated single photon emission computed tomography (SPECT) after a first uncomplicated acute myocardial infarction. METHODS AND RESULTS We used predischarge maximal subjective exercise echocardiography and gated SPECT with technetium 99m tetrofosmin to prospectively study 103 patients younger than 70 years with a first acute myocardial infarction. During a 12-month follow-up period, 2 patients died, 9 had heart failure, and 29 had ischemic complications (4 reinfarction and 25 angina). Predictive variables for heart failure in multivariate analysis were ejection fraction evaluated by echocardiography (odds ratio [OR] 8.5, P =.016) or by gated SPECT (OR 10.7, P =.009). Predictive variables for ischemic complications in multivariate analysis were less than 5 metabolic equivalents (METS) in exercise test (OR 5.2, P =.007) and greater than 15% ischemic extent in the polar map (OR 3.6, P =.04) of SPECT. CONCLUSIONS Exercise echocardiography and Tc-99m tetrofosmin gated SPECT were predictive for heart failure, but exercise SPECT was the only test with predictive power for ischemic complications.

Abstract
A male newborn was admitted to our Unit because of early sepsis and shock. He required antimicrobial therapy and mechanical ventilation and initially did well, although he exhibited jaundice and cholestasis. During the second week he deteriorated, with radiological opacification of the right hemithorax and pleural effusion, and did poorly in spite of antibiotical therapy and drainage of the effusion. In the third week, the X-ray suggested some bowel loops in the right hemithorax. A right-sided diaphragmatic hernia was confirmed by a CT-scan, and surgery was performed with good outcome. The association of delayed-onset right-sided CDH following early sepsis and obstructive jaundice has not been published before, and illustrates a scarcely known form of presentation of this condition.

Abstract
The present study was designed to evaluate the long-term consequences of tryptophan treatment on the central serotonergic activity in the female offspring of rats, and particularly on serotonin-controlled hormone release. During the second half of gestation, tryptophan (200 mg/kg/day) was given daily by stomach intubation to pregnant rats and the brain concentrations of serotonin and 5-hydroxyindole acetic acid and the plasma concentrations of prolactin, progesterone, oestradiol and luteinizing hormone were quantified in the adult female offspring. The offspring showed an increase in hypothalamic serotonin and serum progesterone and prolactin. In addition, maternal ingestion of tryptophan induced a marked rise in 665-day-old offspring in the incidence of both pituitary prolactinomas (62%) and mammary adenomas (49%). Present data suggest that tryptophan regulates serotonergic differentiation during early development. A transitory modification of the tryptophan concentration in the fetal brain induces a permanent increase in hypothalamic serotonin level and, in addition to modifying the release of prolactin, increases the incidence of tumours in the hypophysis and mammary gland.

Abstract
PURPOSE Radiotherapy is widely used in the treatment of bladder cancer. The search for biological parameters that could select patients who will respond to radiation treatment has become essential. The aim of this study is to assess whether the pretreatment apoptotic index is useful in predicting local control and survival in a group of bladder cancer patients treated by radiotherapy. METHODS AND MATERIALS Fifty-five patients with invasive bladder carcinoma treated between 1983 and 1996 were included in this study. Radiotherapy was given to a median dose of 66 Gy, mean 63.28 Gy, in 1.8-2 Gy daily fractions. Apoptotic cells were studied in hematoxylin-eosin slides. Clinicopathological tumor characteristics were studied in relation to the apoptotic index, and as prognostic factors for local control and survival in both univariate and multivariate analysis. RESULTS Pretreatment apoptotic indexes were related to tumor stage, mitotic index, and Ki67 proliferation index. Five-year actuarial local control for the whole group was 45%. Patients with tumors showing low pretreatment apoptotic indexes had better local control (p < 0.037) and survival (p < 0.01) than highly apoptotic tumors. Tumor stage (T2 vs. T3-4) and the pretreatment apoptotic index were significant predictive factors for local control and survival in multivariate analysis. CONCLUSIONS The pretreatment apoptotic index is useful in predicting the clinical outcome of bladder cancer patients treated by radiotherapy. Assessment of biological tumor characteristics could allow the selection of patients for different treatment strategies.

Abstract
Cross-linking the heterotrimeric (alpha beta gamma 2) IgE receptor, Fc epsilon RI, of mast cells activates two tyrosine kinases: Lyn, which phosphorylates beta and gamma subunit immunoreceptor tyrosine-based activation motifs, and Syk, which binds gamma-phospho-immunoreceptor tyrosine-based activation motifs and initiates cellular responses. We studied three Fc epsilon RI-dimerizing mAbs that maintain similar dispersed distributions over the surface of RBL-2H3 mast cells but elicit very different signaling responses. Specifically, mAb H10 receptor dimers induce very little inositol 1,4,5-trisphosphate synthesis, Ca2+ mobilization, secretion, spreading, ruffling, and actin plaque assembly, whereas dimers generated with the other anti-Fc epsilon RI mAbs induce responses that are only modestly lower than that to multivalent Ag. H10 receptor dimers activate Lyn and support Fc epsilon RI beta and gamma subunit phosphorylation but are poor Syk activators compared with Ag and the other anti-Fc epsilon RI mAbs. H10 receptor dimers have two other distinguishing features. First, they induce stable complexes between activated Lyn and receptor subunits. Second, the predominant Lyn-binding phospho-beta isoform found in mAb H10-treated cells is a less tyrosine phosphorylated, more electrophoretically mobile species than the predominant isoform in Ag-treated cells that does not coprecipitate with Lyn. These studies implicate Lyn dissociation from highly phosphorylated receptor subunits as a new regulatory step in the Fc epsilon RI signaling cascade required for Syk activation and signal progression.

Abstract
BACKGROUND Radiotherapy is used in the treatment of laryngeal carcinoma. The search for biologic parameters that could be used to identify patients who will respond to radiotherapy is crucial. The aim of this study was to determine whether the Ki-67 and p53 indices and the pretreatment apoptotic index would be useful in predicting local control and survival for a group of laryngeal carcinoma patients given postoperative radiotherapy. METHODS Fifty-seven patients with laryngeal carcinoma treated between 1988 and 1993 were included in this study. Postoperative radiotherapy was given to a mean dose of 57.7 gray (Gy) (range, 50-68; median, 60) in 2-Gy daily fractions. Ki-67 and p53 immunostaining were performed on paraffin-embedded tissue. Cells were evaluated for apoptosis using hematoxylin and eosin-stained slides. Clinicopathologic tumor characteristics were studied in relation to Ki-67, p53, and apoptotic indices, and as prognostic factors for local control and survival in both univariate and multivariate analysis. RESULTS The Ki-67, p53, and pretreatment apoptotic indices were not related to any clinicopathologic tumor characteristics. Five-year actuarial local control for the whole group was 47%. Patients with tumors that had low Ki-67 proliferation had better long term local control (P < 0.01). and survival (P < 0.03). p53 expression was not predictive of local control or survival in this study. Patients with tumors that had low pretreatment apoptotic indices had better local control (P < 0.049) and survival (P < 0.056) than patients with highly apoptotic tumors. Tumor extension and the pretreatment apoptotic index were significant predictive factors for local control and survival in multivariate analysis. CONCLUSIONS Ki-67 proliferation measurement and the pretreatment apoptotic index are useful in predicting the clinical outcome of laryngeal carcinoma patients referred for radiotherapy. The role of p53 oncoprotein determination in predicting these outcomes is unclear. Assessment of biologic tumor characteristics could aid in the selection of patients for different treatment strategies.

Abstract
A case of signet-ring cell lymphoma affecting bone marrow is reported. The patient was diagnosed as Waldenström's Macroglobulinaemia on the basis of clinical and laboratory features including morphology, immunohistochemistry and gene rearrangement studies. Light microscopy examination showed cells contained large globular inclusions (signet-ring cells) that stained for kappa immunoglobulin light chain by immunohistochemistry. In addition, the neoplastic cells expressed the common leukocyte antigen CD45 and the B cell marker CD19. This to the best of our knowledge is the first report of a patient with Waldenström's Macroglobulinaemia with the presence of vacuolated signet ring- cells in the bone marrow. Differential diagnosis arises with non-haemopoietic tumours and this needs to be based on specific immunostaining. Tumours and this need to be based on specific immunostaining.

Abstract
It has been suggested that a deficit in timing could be the cause of the sensory disturbances reported for Parkinson's disease. To test this hypothesis the temporal discrimination thresholds in four visual tasks were used to study 45 healthy young people, 14 healthy elderly people, and 17 patients with Parkinson's disease. In these tasks, subjects watched a computer controlled light emitting diode display and pushed a button when the visual event previously specified by the researcher was perceived. The time between successive images required to discriminate a visual detail was accurately quantified. In two of the four tasks, the time for visual processing of image sequences was longer in the elderly group than in the young group. No significant differences were found between patients with Parkinson's disease and their age matched controls for any of the four tasks. Present data show normal temporal discrimination and no slowing in the initial steps of visual processing in Parkinson's disease.

Abstract
PURPOSE To assess whether tumour proliferation as measured by Ki67 immunostaining has any predictive value for local control in bladder cancer patients treated by radiotherapy. PATIENTS AND METHODS Fifty-five patients suffering from infiltrating bladder carcinoma recommended for radical radiotherapy (66 Gy/6-7 weeks) were included in this study. Paraffin-embedded pre-treatment tumour sections were stained with the Ki67 antibody. The percentage of Ki67-positive nuclei was correlated with established prognostic factors, local control and survival. RESULTS The Ki67 index was not related to local control in our patients when the median was selected as the cut-off value. Patients with tumours with a very low (<27%) Ki67 index had better local control at 5 years (69%) than patients with tumours with greater (>27%) Ki67 expression indices (31.5%) (P<0.05; log-rank test). CONCLUSIONS Ki67 immunostaining was a feasible method to estimate tumour proliferation. Patients with very low proliferating tumours seemed to achieve better local control after fractionated radiotherapy compared to other patients. Further studies are needed with a greater number of patients to accurately define the role of Ki67 expression in predicting tumour repopulation during fractionated radiotherapy.

Abstract
The effect of tryptophan administration to pregnant rats on the development of serotonergic systems and serotonin-related hormones in the offspring was studied. The male offspring of rats treated with tryptophan (200 mg/kg/day) during the second half of gestation showed a 4- to 7-fold increase in serum prolactin 40 and 70 days after birth and a 2-fold increase in serum luteinizing hormone 70 days after birth. The forebrain of adult offspring of tryptophan-treated rats showed an increase in serotonin and 5-hydroxyindoleacetic acid levels. Present data suggest that tryptophan regulates serotonergic differentiation during early development.

Abstract
This paper presents data suggesting a relationship between rat behavioral despair in the Porsolt test and motor lateralization in the T-maze test. In addition, experimental evidence suggests a functional coupling among dopaminergic systems, behavioral despair and motor lateralization. In the first experiment, female, not male, rats with a high level of behavioral despair showed a low level of behavioral lateralization. The inverse relationship was found in female offspring of mothers stressed during gestation. In comparison with unstressed-mother rats, the female offspring of stressed mothers showed an increase of dopamine (DA) and a decrease of dihydroxyphenylacetic acid (DOPAC) and Homovanillic (HVA) levels and of DOPAC:DA and HVA:DA indexes in the n. accumbens of the right side of the brain. No significant differences were found in the n. accumbens of the left brain. Taken together, the present data provide evidence of a relation between behavioral despair and motor lateralization, suggesting that the biological dopaminergic inervation of n. accumbens could be the basis for this functional coupling. Because the stress of gestant mothers modified these biochemical and behavioral variables, the present study also suggests that lateralization of behavior and emotion during adulthood can be modified by prenatal variables.

Abstract
Twenty-four h changes in endogenous tyrosine hydroxylase (TH) activity, monoamines and their metabolites as well as N-acetyltransferase (NAT) activity and melatonin content were investigated in the Syrian hamster pineal gland. Both NAT activity and melatonin content exhibited an expected rise 8 h (0400 h) after darkness onset. Pineal dopamine (DA) and 3,4-dihydroxyphenyl acetic acid (DOPAC) levels were highest during the dark phase reaching a peak at 0200 h, just prior to the rise in melatonin production. However no significant difference were found in both norepinephrine (NE) and TH activity levels during the 24 h period. However, in the present study, the rat pineal gland exhibited a clear day/night difference in its TH activity. These data suggest a possible role of pineal DA in the induction of melatonin synthesis in addition to its function as a NE precursor in the Syrian hamster pineal gland and also indicate that catecholamines may act on the hamster pineal in a different manner than in the rat.

Abstract
Membrane receptors for the Fc portion of immunoglobulin G (IgG) antibodies (Fc(gamma)Rs) are expressed on almost every type of hematopoietic cells, where they mediate a wide variety of effector functions. A high degree of structural heterogeneity exists among Fc(gamma)Rs. The biological significance of such heterogeneity is unknown, since the structural diversity does not appear to be reflected in the binding specificity nor in the effector functions that each distinct receptor is able to mediate. Recent work has emphasized the essential role of protein tyrosine phosphorylation in the initiation of transmembrane signaling by these receptors. In this article we review the role of protein tyrosine phosphorylation in signal transduction by the different types of Fc(gamma)Rs in order to assess to what extent the structural heterogeneity of this receptor family is related to different activation pathways utilized by each of its members.

Abstract
When HeLa cells were selected for stable expression of a neo gene, linked either to mutated or wt c-H-ras genes, morphological examination of selected clones from several experiments revealed formation of giant multinucleated cells. These morphological alterations culminate in cell death, as a consequence of mitotic catastrophe (or mitotic death). Although clones expressing the mutated gene produced significantly larger numbers of these giant cells, those transfected with the normal allele were also found to produce significantly more giant multinucleated cells than non-transfected HeLa cells. Northern blot analysis of mRNA revealed overexpression of the normal H-ras gene in these clones. Chromatin structure analysis of these clones showed gross alterations, including the presence of micronuclei and heteroploid nuclei. Interestingly, odd numbers of nuclei were found in colonies of these giant cells. In addition, alterations in cell cycle parameters were observed, including the appearance of a subpopulation of cells with an abnormal content of DNA, probably representing dying cells. Our data support the notion that abnormal expression of H-ras contributes to mitotic catastrophe and death of a subpopulation of HeLa cells.

Abstract
PURPOSE The splenic lymphoma with circulating villous lymphocytes (SLCVL) is an infrequent disease included within the low grade non Hodgkin's lymphoma, B-cell type. The results of the study of four patients are reported. PATIENTS AND METHODS Clinical, cytological, immunophenotypic, ultrastructural, evolutive and therapeutic data have been revised in all the cases. RESULTS Two males and 2 females of 76, 66, 68 and 62 years, respectively were diagnosed as having SLCVL. The initial symptoms were scarce, basically asthenia, and a big spleen without significant lymphadenopaty was the most relevant physical finding in each of them. In peripheral blood leukocyte count was normal with a slight lymphocytosis and a variable percentage of villous circulating lymphocytes. The immunophenotype of peripheral blood obtained by flow cytometry was according with a mature B-cell lymphocyte population, CD 5 and CD 25 negative. The cells were positive to acid phosphatase with a diffuse pattern of variable intensity; the reaction was inhibited by tartaric acid. All the patients had BM infiltration, studied with aspiration and biopsy. One case (M,66) had an IgM monoclonal gammopathy. The ultrastructural study, performed in 3 cases, showed thin and short villous prolongations. After splenectomy, a low degree lymphoma therapy has been employed in all the cases. The follow-up ranges between, 4 years and 4 months, all the patients being alive. CONCLUSIONS The SLCVL is a definitive entity regarding the clinical, morphologic and immunophenotype features. A long clinical evolution and a good prognosis after splenectomy are common.

Abstract
During 1991, 52 patients undergoing myocardial revascularization had a biopsy of the distal internal left mammary artery (IMA) taken. There were 48 male and 4 female patients with a medium age of 58 years. Arteriosclerotic involvement of the IMA was assessed according to the scale of Kay. Using this index, grade 0 corresponds to a normal artery without atherosclerosis, grade 1 represents minimal disease, grade 2 a narrowing of less than 25% of the lumen, grade 3 narrowing between 25 and 50%, and grade 4 narrowing of 50% or greater of the lumen. Of the 52 IMA examined, the arteries with degree 0, 1, 2, 3, and 4 were: 19 (36.5%), 20 (38.4%), 9 (17.6%), 4 (7.6%) and zero. Thirty-three arteries (63.4%) had some degree of atherosclerosis. Considering the arteries with some atherosclerotic narrowing, 13 (25%) of the whole group had this pathological alteration. The IMA has a low but consistent incidence of arteriosclerosis involvement. Preoperative angiographic investigation of the IMA could be routinely performed.

Abstract
Time-dependent modifications of N-acetyltransferase (NAT) activity, melatonin content, and tyrosine hydroxylase (TH) activity within the isolated rat pineal over a 72 h of incubation period were studied. Both pineal NAT activity and melatonin content displayed similar decreases after 12 h of incubation, and reached a maximal reduction of 82% or 93%, respectively, after 48 h. However, a maximal decrease of pineal TH activity was only 47% after 72 h of incubation. Neither the nuclear area of pinealocytes, nor lactate dehydrogenase (LDH) activity in the incubation medium showed any significant variation dependent on the incubation time. Treatment with isoproterenol caused an expected elevation of NAT activity and melatonin content but was unable to modify TH activity. Since a significant degree of pineal TH activity remained following 3 days of incubation, a non-sympathetic source of TH within the rat pineal gland is suggested.

Abstract
The microbial secondary metabolites are compounds with a wide range of chemical structures, produced mainly by actinomycetales and some fungi, usually in the late growth phase. Although a high proportion of this metabolites are antibiotics, there are also examples with pigment, herbicide and surfactant properties. Its function has been correlated to bacterial pathogenicity and cellular differentiation, however, properties dealing with chelation, hormonal and antitumor activities as well as nutritional reserve have been also reported. As in other examples of cellular compounds, the secondary metabolites are produced from low molecular weight precursors. For this purpose, specific biosynthetic pathways are utilized and regulated by processes which generally affect either the activity or the synthesis of the enzymes involved in it. Considering the secondary metabolites apparently are dispensable compounds, there are difficulties to explain their existence from an evolutionary point of view. Explanations to their existence have gone from laboratory artifacts to those conferring them an adaptative value in the past. It seems that they were maintained due to selective advantages to the producer microorganisms and probably, their sometimes complex biosynthetic pathways, have emerged from primary metabolites and evolved later independently by random mutation, amplification and genetic transfer.

Abstract
It was previously reported that oral administration of tyrosine (500 mg/kg) to pregnant rats increases tyrosine and monoamines level in the fetal brain and modifies locomotion during postnatal life. In the present study, it was found that this treatment alters behavioral lateralization in the offspring. Neonatal rats whose mothers received tyrosine during the second half of gestation showed a low level of absolute and population laterality in both tail and head movements. The alteration of behavioral lateralization was also found during postnatal development and during adulthood. The T-maze behavioral ontogeny was different for tyrosine-mother and sham-treated or untreated mother rats. During adulthood, the T-max lateralization after stress sessions (a procedure that decreases alternation behavior and facilitates the quantification of behavioral lateralization) was also different in control and tyrosine-mother groups. Neonatal and adult rats showed an increase in right-side movements probability. These data provide evidence that maternal ingestion of a catecholamine precursor during gestation may induce a long-lasting modification of the behavioral lateralization of the offspring.

Abstract
It has been previously reported that tyrosine ingestion by the mother rat during gestation modifies different behavioral patterns in the adult offspring. In the present study, the action of maternal mother tyrosine ingestion on the postnatal development of the dopaminergic system of the offspring was evaluated. The offspring of tyrosine-treated mothers showed a decrease in dopamine (DA) levels during the first 15 days of postnatal life and an increase in DA levels from day 30 to adulthood. The DOPAC level and the DOPAC/DA index were higher in the tyrosine group from postnatal life to adulthood. These differences reach statistical significance in both forebrain and mesencephalon. During adulthood the DA concentration in both s. nigra and ventral tegmental area were higher in the tyrosine group than in the control group. The behavioral postsynaptic response to a DA receptor agonist (apomorphine) was higher in the offspring of tyrosine treated rats than in the control group. These data suggest that the bioavailability of the DA precursor tyrosine during gestation may modify during postnatal life DA synapsis at both pre- and postsynaptic level.

Abstract
In the present study the right-left brain asymmetry of central dopamine (DA) systems during postnatal brain development is evaluated. DA and dihydroxyphenylacetic acid (DOPAC) levels increased from neonatal to adult life in both the forebrain and mesencephalon. This increase was not similar in the right and left brain sides. From neonatal life to adulthood a fall was observed in (a) DA percentage in the DA high-brain side in the mesencephalon and (b) DOPAC percentage in the DOPAC high-brain side in both the forebrain and mesencephalon. The percentage of lateralized rats (more than 65% of DA or DOPAC levels in either brain side) also decreased during ontogeny. Thus, biochemical lateralization decreases during ontogeny. The right-left brain correlation for DA level and DA turnover was used to evaluate the inter-hemispheric regulation of dopaminergic systems. The correlation coefficient was near to 0 during postnatal life and around -0.8 during adulthood in both forebrain and mesencephalon. Taken together, these data suggest that the ontogenic decrease of in brain asymmetry for DA or DOPAC levels is related to the postnatal development of an inter-hemispheric regulatory system that control dopaminergic neurons activity.

Abstract
A method for the preparation of new aminated agarose gels containing monoaminoethyl-N-aminoethyl structures, MANA-agarose gels, has been developed. These gels contain primary amino groups with a very low pK value (6.8). In addition to that, we have been able to prepare very highly activated gels (e.g., 10% agarose gels containing up to 200 mu Eq of primary amines per milliliter). These two properties make these activated supports suitable for performing novel and interesting methods for protein immobilizations via very mild carbodiimide activation of carboxy groups. For example, very effective coupling reactions can be performed at pH 5.0-6.0 in the presence of low concentrations of activating agent, e.g., 1 mM. By using a model industrial enzyme, beta-galactosidase from Aspergillus oryzae, we have been able to demonstrate the excellent prospects of these novel activated supports.

Abstract
Behavioral lateralization has previously been reported in adult animals. This work presents a study of behavioral laterality and spontaneous alternation behavior in 156 neonatal rats (39 litters with two males and two females per litter). The initial tail and head lateral movements (axis body-tail or head higher than 30 degrees) were recorded after neonatal rats were gently placed along a straight line drawn on a glass surface. This test was repeated 10 times. A leftward population lateralization was found for tail movement while head movement was rightward. The alternation behavior was lower (10-25%) than that previously reported for adult rats (80-90%) and than that expected if movement was made at random (50%). Males were more lateralized than females for head and tail movements. No sex differences were observed for behavioral alternation. In 2-day-old rats (10 litters with one male and one female per litter), the right brain side had a higher content in dopamine (mesencephalon) and DOPAC (proencephalon) than the left brain side. Thus, we concluded that behavioral and biochemical asymmetries in animals are conditioned by phenomena present during prenatal or early neonatal (first hours after birth) life and that spontaneous alternation behavior is not present during the earlier stages of postnatal development.
