MEDISAN , 2012,
Abstract: Se realizó un estudio observacional, descriptivo y transversal de 175 pacientes con trastornos del movimiento que asistieron a la Consulta de Neurología del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" desde el 2007 hasta el 2010, con vistas a describir la morbilidad en estos. Dichas afecciones iniciaron durante la quinta y sexta décadas de la vida en la mayoría de los integrantes de la casuística, con una frecuencia superior de la enfermedad de Parkinson, el temblor esencial y las distonías, y prevalencia del sexo masculino y el color de la piel mestizo. La electromiografía de los músculos agonistas y antagonistas evidenció el predominio del temblor de reposo y la disfunción en la inhibición recíproca, sobre todo en la enfermedad de Parkinson. An observational, descriptive and cross-sectional study of 175 patients with movement disorders who attended the Neurology Department in "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital was carried out from 2007 to 2010, aimed at describing the morbidity in them. These disorders began during the fifth and sixth decades of life in most of the members of the case material, with a higher frequency of Parkinson disease, the essential tremor and dystonias, and prevalence of the male sex and half-bred skin. The electromyography of the agonistic and antagonistic muscles evidenced the prevalence of the rest tremor and the disorder in the reciprocal inhibition, mainly in the Parkinson disease.

Abstract: In the present work, the susceptibility of API 5L X52 steel to corrosion processes was evaluated in the presence of high contents of hydrogen sulfide and carbon dioxide. Gravimetric tests and surface analyses were carried out to establish both the corrosion rate and damage type exhibited by the metal. The obtained results indicate that the hydrogen sulfide is the most active gas in the corrosion processes that took place, quite above carbon dioxide. The main observed corrosion products were iron sulfides and the typical damage associated with hydrogen sulfide presence was Sulfide Stress Cracking (SSC). The surface damage evidences the presence of cracks with considerable magnitude and metal loss as consequences of the corrosion processes. Likewise, the presence of oxygen in the system modifies the displayed corrosion type, where corrosion products such as iron oxides and reduction in the number and extent of cracks are observed. On the other hand, the addition of a film-forming corrosion inhibitor based on modified imidazolines eliminates completely the development of cracks, although under certain test conditions, it can favor localized pitting corrosion.

Abstract: The theory of false alarm for laughter could explain the involuntary laugh when someone is tickled. To put this hypothesis to the test, we handed out a questionnaire (180 items) with two hundred university students. Our main results are: In women who like being tickled, we discover components related to pleasure, erotism, feeling of affection, arousal, uncontrollability, domination, sexism and Darwinian (golden ratio) and psychological traits (empathy, low schizotypy and external locus of control) that are not present in the laughter at a stumble. The relation of both types of laughter with sense of humor is also differential. In men who like being tickled, we discover components related to masturbation, sexual fantasies, erotism, arousal, domination, sexist humour and Darwinian (square chin, feeling of masculinity) and psychological traits (empathic stress, low schizotypy, external locus of control and overall self-esteem). The relationship between being tickled and self-esteem shows a double aspect in men: It is positive in men who like being tickled and negative in men who do not like being tickled. For women there is not a relationship between self-esteem and tickling. Our conclusion is that laughter of ticklishness is a Darwinian feature related to empathy.

 

Structural and functional analysis of the Entamoeba histolytica EhrabB gene promoter

BMC Molecular Biology , 2007, DOI: 10.1186/1471-2199-8-82
Abstract: To initiate the knowledge of EhrabB gene expression regulation, here we studied the structural characteristics of its gene promoter and its control transcription elements. In silico searches of the EhrabB 5'-flanking region revealed that it contains a motif similar to the upstream regulatory element 1 (URE1) of the E. histolytica hgl5 gene. It also has sequences with homology to C/EBP and GATA1 binding sites, and heat shock elements (HSE). Primer extension experiments revealed that EhrabB has at least four transcription initiation sites. The elements at the 5'-flanking region that drive EhrabB gene expression were detected and characterized using transitory transfected trophozoites with a plasmid carrying the CAT reporter gene. EhrabB transcription is negatively regulated by a sequence located between positions -491 to -428 with respect to the first transcription initiation site. We also showed that the URE1-like motif activates EhrabB transcription. In addition, heat shock activated the EhrabB promoter in episomal constructs and lead to an increase in de novo EhrabB transcription.The data suggest that EhrabB transcription is controlled negatively by an unidentified sequence, but it is activated by an URE1-like motif. Our analyses also revealed the presence of activator HSE that function under stress.Entamoeba histolytica is the protozoon responsible for up to 100,000 deaths each year [1]. Only 10% of infected people present disease symptoms expressed in intestinal or extraintestinal amoebiasis. The molecular mechanisms participating in the parasite invasiveness are not completely understood. Diverse populations of E. histolytica, including clones derived from a particular strain, display different virulence phenotype [2-4]. In addition, long-time cultured trophozoites, which show poor capacity to produce liver abscesses in experimental animals, recover their virulence after incubation with cholesterol or with certain types of bacteria, or after their passage by ham

Abstract: An 83-year-old Caucasian man was hospitalized with a 2-month history of back pain, anorexia, generalized weakness and a 47-pound weight loss. He had previously undergone two transurethral resections for high-grade transitional cell carcinoma of the bladder and had received 12 intravesical bacillus Calmette-Guerin instillations without any complications. He complained of abdominal pain in his right flank. A computed tomography scan of the abdomen showed multiple abscesses affecting the pancreatic head and right psoas muscle. Growth of Mycobacterium bovis was determined in cultures of the purulent material obtained by surgical drainage of the abscesses.This case illustrates the fact that although intravesical administration of bacillus Calmette-Guerin is generally considered to be safe, it is not exempt from complications and these could appear immediately after treatment or as a delayed complication many years later.Bacillus Calmette-Guerin (BCG) is a live attenuated strain of Mycobacerium bovis that has been used to treat urothelial carcinoma since 1976 and has been reported to eradicate disease in more than 70% of patients with in situ and stage I disease [1]. Although intravesical therapy with BCG is generally considered safe, serious complications including hematuria, granulomatous pneumonitis, suppurative lymphadenitis, distant intramuscular and bone abscesses, hepatitis, and life-threatening BCG sepsis have been documented [2]. The reported incidence of complications other than minor ones is under 5% [3]. To the best of our knowledge, we report the first case of disseminated BCG infection causing multiple abscesses affecting the pancreatic head and right psoas muscle diagnosed 5 years after intravesical treatment with BCG therapy for bladder cancer.An 83-year-old Caucasian man was hospitalized with a 2-month history of back pain, anorexia, generalized weakness and a 47-pound weight loss. The patient had previously undergone two transurethral resections for high

Abstract: orally ingested probiotic bacteria are able to modulate the immune system. however, differences exist in the immunomodulatory effects of different probiotic strains. moreover, different regulatory effects, which depend on the health status of the consumer, have been identified. this work describes a randomized, double-blind, placebo-controlled human clinical trial to investigate the immune effects on healthy people of a fermented product containing two new probiotic strains, lactobacillus gasseri cect 5714 and lactobacillus coryniformis cect 5711, which was compared with another fermented product, a standard yogurt. consumption of either the new product or yogurt increased the proportion of phagocytic cells, including monocytes and neutrophils, as well as their phagocytic activity. however, combination of the product containing the strains l. gasseri cect 5714 and l. coryniformis cect 5711 also induced an increase in the proportion of natural killer (nk) cells and in iga concentrations. the effects were higher after two weeks of treatment than after 4 weeks, which suggests regulation of the immune system. in addition, the new product enhanced immunity in the participants to a greater extent than did the control standard yogurt.

Abstract: For a better comprehension of the structure-function relationship in proteins it is necessary to identify the amino acids that are relevant for measurable protein functions. Because of the numerous contacts that amino acids establish within proteins and the cooperative nature of their interactions, it is difficult to achieve this goal. Thus, the study of protein-ligand interactions is usually focused on local environmental structural differences. Here, using a pair of triosephosphate isomerase enzymes with extremely high homology from two different organisms, we demonstrate that the control of a seventy-fold difference in reactivity of the interface cysteine is located in several amino acids from two structurally unrelated regions that do not contact the cysteine sensitive to the sulfhydryl reagent methylmethane sulfonate, nor the residues in its immediate vicinity. The change in reactivity is due to an increase in the apparent pKa of the interface cysteine produced by the mutated residues. Our work, which involved grafting systematically portions of one protein into the other protein, revealed unsuspected and multisite long-range interactions that modulate the properties of the interface cysteines and has general implications for future studies on protein structure-function relationships.

Abstract: the entomopathogenic nematodes belonging to heterorhabditis and steinernema genera are efficient biological control agents for insects. several strains of heterorhabditis spp. have been studied and developed in cuba, and they have been used successfully in pest management. in 2005, specialists from the national center for animal and plant health (censa) transferred the technology for mass rearing of entomopathogenic nematodes on galleria mellonella to the national phytosanitary reference center for the mountain (cnrfm), and the native strain hc1 of heterorhabditis bacteriophora was used to be evaluated in coffee berry borer (hypotenemus hampei ferrari) management. seven batches of entomopathogenic nematodes were produced in the first three months and mean yields of 190 000 ij larvae-1 were obtained since batch no. 4, a value very close to the real productive potential of the strain. in relation to the viability (% of live juveniles), it was close to 90% since batch no. 2. as an indicator of a successful technology transfer, the specialists from cnrfm produced more than 291 millions of infestive juveniles (lj) of the strain hc1 of h. bacteriophora. the lj produced showed to be pathogenic to larvae of spodoptera frugiperda (j.e. smith), diaphania hyalinata (l.) and manduca sexta (l.) with 100% mortality at 48 hours.
