RESUMO

Along the West Coast of Barbados a unique relationship has developed between endangered green sea turtles (Chelonia mydas) and humans. Fishermen began inadvertently provisioning these foraging turtles with fish offal discarded from their boats. Although initially an indirect supplementation, this activity became a popular attraction for visitors. Subsequently, demand for this activity increased, and direct supplementation or provisioning with food began. Food items offered included raw whole fish (typically a mixture of false herring [Harengula clupeola] and pilchard [Harengula humeralis]), filleted fish, and lesser amounts of processed food such as hot dogs, chicken, bread, or various other leftovers. Alterations in behavior and growth rates as a result of the provisioning have been documented in this population. The purpose of this study was to determine how tourism-based human interactions are affecting the overall health of this foraging population and to determine what potential health risks these interactions may create for sea turtles. Juvenile green sea turtles (n=29) were captured from four sites off the coast of Barbados, West Indies, and categorized into a group that received supplemental feeding as part of a tour (n=11) or an unsupplemented group (n=18) that consisted of individuals that were captured at sites that did not provide supplemental feeding. Following capture, a general health assessment of each animal was conducted. This included weight and morphometric measurements, a systematic physical examination, determination of body condition score and body condition index, epibiota assessment and quantification, and clinical pathology including hematologic and biochemical testing and nutritional assessments. The supplemented group was found to have changes to body condition, vitamin, mineral, hematologic, and biochemical values. Based on these results, recommendations were made to decrease negative behaviors and health impacts for turtles as a result of this provisioning.

RESUMO

BACKGROUND: Connect MM is the first and largest observational, noninterventional, prospective registry of patients newly diagnosed with multiple myeloma (NDMM) in the United States. It collects longitudinal data on patients within clinical practice including patients in clinical trials. PATIENTS AND METHODS: Of the 1513 patients enrolled, 1493 were protocol-eligible. RESULTS: Median age was 67 years, 81.9% (1223/1493) were Caucasian, and 57.2% (854/1493) were male. Of these patients, 26.5% (232/877) were International Staging System stage I, 34.9% (306/877) stage II, and 38.7% (339/877) stage III. Eastern Cooperative Oncology Group performance status of 0/1/2 were reported in 96.6% (1017/1053). Clonal plasma cells > 10% were found in 91.6% (1282/1399) of patients and M-component in 98.8% (1343/1359). Hypercalcemia was present in 7.3% (108/1481) of patients, serum creatinine > 2 mg/dL in 18.3% (271/1484), anemia in 45.1% (673/1493), and bone involvement in 76.7% (1143/1490). Of the 15 National Comprehensive Cancer Network (NCCN) recommended diagnostic tests, a median of 12 were performed. Lactate dehydrogenase assessment, serum free light chain ratio, and immunofixation were reported in 38.4% (574/1493), 62.1% (927/1493), and 66% (985/1493) of patients, respectively. Quantitative immunoglobulin, ß-2 microglobulin, and protein electrophoresis (serum or urine) were reported in 72.3% (1080/1493), 74.1% (1107/1493), and 78.0% (1164/1493) of patients, respectively. Bone marrow biopsy was reported in 92.2% (1376/1493), but conventional cytogenetic and fluorescence in situ hybridization analysis were reported in only 63.2% (944/1493) and 59.8% (893/1493) of patients, respectively. A high-risk cytogenetic profile (according to International Myeloma Working Group [IMWG] criteria) was found in 16.9% (253/1493). CONCLUSION: This analysis provides insight into the demographic and disease characteristics of NDMM patients in a range of clinical practices. Creating solid records of baseline patient disease characteristics using suggested NCCN diagnostic work-up and IMWG criteria provides a foundation for monitoring disease progression and response to treatment.

RESUMO

Antecedentes: El polen de la morera del papel se considera uno de los aeroalérgenos más relevantes en Pakistán, cuyas propiedades alergénicas no han sido estudiadas hasta el momento actual. Objetivo: El objetivo de este estudio fue caracterizar el perfil de sensibilización de los pacientes alérgicos a las proteínas de este polen que contribuye a la polinosis en Pakistán. Métodos: La extracción de las proteínas de este polen fue realizada mediante diferentes protocolos. La unión de la IgE a proteínas del polen de la morera del papel, perteneciente a la familia de las moráceas fue determinada mediante InmunoCAP e Inmunoblotting utilizando suero de 29 pacientes alérgicos a este polen con prueba cutánea positiva. Se realizó test de liberación de histamina in vitro para determinar la potencia alergénica de los extractos de polen y de un alérgeno parcialmente purificado. Se secuenciaron la N-terminal y MALDI-TOF/TOF para identificar la proteína. Resultados: En cuanto a los resultados obtenidos se confirmó la sensibilización a dicho polen mediante ImmunoCAP frente a polen de Morus alba en 23 de los 29 pacientes alérgicos al polen de morera del papel. Una proteína de 10 kDa del extracto de dicho polen se consideró como el alérgeno mayor sobre el resto de las proteínas reactivas a la IgE. El suero del 79% de los pacientes reaccionó con este alérgeno de 10 kDa, el cual mostró capacidad para liberar histamina in vitro en 3 de 4 pacientes. La secuenciación N-terminal y MALDI-TOF/TOF arrojó una secuencia de aminoácidos con ausencia de homología con otras proteínas conocidas. Conclusiones: En conclusión, los pacientes alérgicos al polen de morera del papel están sensibilizados a múltiples alérgenos de este polen. Se identifica una nueva proteína de 10 kDa como alérgeno mayoritario que deberá ser investigado con fines diagnósticos y terapéuticos (AU)


Background: Paper mulberry (Morus papyrifera) pollen is considered to be one of the most clinically relevant aeroallergens in Pakistan. To date, the allergenicity of the pollen has not been investigated. Objective: To characterize the sensitization profile of mulberry-allergic patients and the proteins of paper mulberry pollen contributing to pollinosis in the Pakistani population. Methods: Proteins were extracted from mulberry pollen using different protocols. Immunoglobulin (Ig) E binding proteins to mulberry pollen was determined by ImmunoCAP testing and immunoblotting using sera from 29 mulberry pollen–allergic patients with positive skin prick test results to mulberry pollen antigens. The histamine release assay was performed in vitro to determine the allergenic potency of pollen extracts and a partially purified mulberry pollen allergen. The protein was identified using N-terminal sequencing and matrix-assisted laser desorption/ionization–time of flight spectrometry (MALDI-TOF/TOF). Results: IgE sensitization to mulberry pollen was confirmed by positive ImmunoCAP results to pollen from Morus alba (white mulberry) in 23 out of 29 mulberry pollen–allergic patients. A 10-kDa protein from the paper mulberry pollen extract was considered a major allergen, along with additional IgE-reactive proteins. Sera from 79% of the patients reacted to the 10-kDa allergen, which showed substantial capacity to trigger histamine release in 3 out of 4 patients. N-terminal sequencing and MALDI-TOF/TOF yielded an amino acid sequence with no homology to known proteins. Conclusions: Mulberry-allergic patients are sensitized to multiple mulberry pollen allergens. We identified a novel 10-kDa protein that was a major allergen and should be further investigated for diagnostic and therapeutic purposes (AU)

RESUMO

OBJECTIVE: To explore the relationship of Pi-deficiency syndrome in TCM with the change of serum high density lipoprotein (HDL) in blood lipid metabolic disorder. METHODS: Sixty-eight patients with confirmed coronary heart disease (CHD) were selected for TCM syndrome typing into Pi-deficiency (PD) group and non-Pi-deficiency (NPD) group. Routine blood lipids and serum lipoprotein electrophoretogram (SLPG) were determined in all patients to analyze the total content of HDL and its relative contents of sub-components HDL(1-5), as well as their relation with PD syndrome. Besides, a healthy control group (62 cases) was set up. RESULTS: The level of serum HDL-C was lowered, SLPG abnormality rate increased in the patients with CHD, with total HDL and the relative contents of subcomponent HDL(1) and HDL(3) significantly lower than those in the healthy control group (P<0.01). The total HDL, HDL(1) and HDL(3) in the PD group were also lower than those in the NPD group (P<0.05, P<0.01). CONCLUSION: Serum HDL and its sub-components showed a definite relation with TCM PD syndrome type, therefore, further exploring the granular specificity of HDL and its sub-components as well as their influence on reverse cholesterol transport (RCT) may hopefully provide clues for developing RCT regulatory Chinese new drugs and for CHD prevention and treatment.

RESUMO

OBJECTIVE: The purpose of this study was to establish two-dimensional gel electrophoresis (2-DE) profiles of serum of myasthenia gravis patients, and to identify the differential proteomic expressions between normal persons and myasthenia gravis patients with spleen and kidney deficiency syndrome. METHODS: Samples of serum protein were extracted by repeated freeze-thaw method and separated by two-dimensional electrophoresis. Differential proteomic expressions between the myasthenia gravis patients and the normal control persons were identified by two-dimensional polyacrylamide gel electrophoresis, silver staining, image-master 2-DE software analysis, peptide mass fingerprinting based on matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS), BioWorks and NCBI software database searching. RESULTS: The two-dimensional polyacrylamide gel electrophoresis profiles of serum proteins were successfully established by 2-DE. Twenty-one of the significant differential proteins were selected and identified by MALDI-TOF-MS. Eight of them were finally identified. CONCLUSIONS: The 2-DE profiles of serum proteins were established and the differential proteomic expressions were identified by proteome technique in our study. This can be an experimental basis for further research of the pathogenesis and treatment of myasthenia gravis.

RESUMO

The effects of treatment/prophylaxis of newborn calf colibacillosis with tryptic casein hydrolysate (TCH), recently shown to be a novel type of antimicrobial acting through stimulation of the microbial autolytic system, versus an authorized veterinary drug, Fermosorb, were evaluated. Both products showed similar high therapeutic and prophylactic efficacies, but hematological indices and daily weight gain of cured/protected animals were better with TCH. The differences in hemoglobin and hematocrit levels, total protein, gamma-globulin and sulfhydryl group quantities, bactericidal and lysozyme activities as well as daily weight gain at the end of treatment/prophylaxis were statistically significant (P<0.05-0.000005). Statistically significant differences (P<0.05-0.0005) in favor of TCH were also observed when bactericidal activity, total protein quantity of serum as well as daily weight gain of the animals were compared on the 90th day after birth. We conclude that TCH acts not only as an antimicrobial, but also as an immunostimulant (and growth promoter). The immunostimulatory activity of TCH most probably derives from a synergistic action of bioactive peptides encrypted in the preparation itself and the cell wall fragments resulting from microbial autolysis induction.

RESUMO

Total proteins and protein electrophoresis were made in the sera of broiler chicken (Arber Acres) to evaluate the effect of substitution of basal diet for 4 weeks by either 8% sugar cane bagasse +2% wheat germ or 16% sugar cane bagasse +4% wheat germ whether untreated or incubated with rumen liquor for 72 h and then sterilized with 2 Mrad gamma-irradiation (treated). Both levels of untreated sugar can bagasse (8 and 16%) showed significant decrease in gamma globulins but this decrease had no effect on broiler chicken (45 days) while there was significant increase in total proteins in treated sugar cane bagasse 8% with concomitant increase in alpha 2, beta 1, beta 2 and gamma globulins. These results denoted that addition of rumen liquor to 8% sugar cane bagasse diet have resulted in an improvement in the transportation of micro nutrients and immune response most probably due to its high content of microorganisms constituting high quality animal protein; also more vaccines were recommended in feeding of chicken with sugar cane bagasse for a longer period e.g. laying hens to overcome its suppressive effect on the gamma globulins.

RESUMO

BACKGROUND: Hereditary spherocytosis (HS) is characterized by osmotically fragile spherocytic red cells (RBCs), mild to moderate hemolysis, and splenomegaly. Little is known about the safety of blood bank storage of HS RBCs. CASE REPORT: A 50-year-old man with mild autosomally dominant HS asked to make an autologous RBC deposit before his scheduled surgery. His RBCs were serially tested for osmotic fragility during 4 weeks of blood bank storage in CPD with adenine-saline. Aliquots of his fresh and 4-week-old RBCs were also labeled with 51Cr for measurement of in vivo survival. The osmotic fragility of the patient's fresh RBCs was normal, with 50-percent hemolysis at approximately 0.43-percent NaCl and a sigmoid lysis curve. Incubated osmotic fragility (24 hours at 37 degrees C) was abnormal, with 50-percent hemolysis at 0.64-percent NaCl. Median survival of his fresh 51Cr-labeled RBCs was moderately shortened at 17.5 days. Osmotic fragility increased during storage, with 50-percent lysis occurring at 0.58-percent and 0.62-percent NaCl after 2 and 4 weeks, respectively. Volunteer normal donor RBCs exhibited 50-percent lysis in 0.48-percent NaCl after 4 weeks. Median survival of the patient's 4-week-old 51Cr-labeled RBCs was severely shortened, at 3.5 days. At surgery, intraoperatively salvaged RBCs demonstrated osmotic fragility identical to that of the patient's RBCs freshly obtained by venipuncture. CONCLUSION: HS RBCs may lose membrane under optimum storage conditions, becoming unsuitable for transfusion at surgery. Intraoperative autologous transfusion may be preferable to preoperative deposit for avoidance of allogeneic RBC transfusion in patients with HS.

RESUMO

The influence of palmitic acid, 13-cis-retinoic acid, all-trans-retinoic acid, and all-trans-retinol on the activity of the human cholesteryl ester transfer protein (CETP) was evaluated either in total human plasma supplemented with a tracer dose of 3H-labeled cholesteryl-ester-containing high-density lipoprotein sub-fraction 3 ([3H]CE-HDL3), or in reconstituted mixtures containing [3H]CE-HDL3, isolated low-density lipoproteins (LDL), and purified CETP. In reconstituted mixtures, all the carboxylated derivatives increased progressively and significantly the transfer of 3H-labeled cholesteryl esters from [3H]CE-HDL3 towards LDL in the 20-100 microM concentration range. Under identical experimental conditions, CETP activity was only minimally modified in the presence of all-trans-retinol. When present at a concentration of 60, 80, or 100 microM, 13-cis-retinoic acid was a significantly more potent activator of CETP activity than all the other derivatives studied (P < 0.01 in all cases). In contrast to observations made with reconstituted mixtures, only 13-cis-retinoic acid, but not palmitic acid, was able to induce a significant, concentration-dependent stimulation of CETP activity in total human plasma. In fact, differences in the ability of 13-cis-retinoic acid and palmitic acid to modulate the plasma cholesteryl ester transfer reaction were linked to their relative affinity for albumin and lipoprotein substrates: fatty-acid-poor albumin reduced CETP activity to a significantly greater extent in reconstituted mixtures containing palmitic acid than in reconstituted mixtures containing 13-cis-retinoic acid (P < 0.01 for all the incubation mixtures in the 1-10 g/l albumin concentration range); palmitic acid presented a markedly lower ability to increase the electrophoretic mobility of LDL and HDL fractions in total plasma than 13-cis-retinoic acid. In support of a key role of the negatively charged carboxylic group of 13-cis-retinoic acid in upregulating CETP activity, cholesteryl ester transfer rates correlated positively with the electrophoretic mobility of LDL (r = 0.98; P < 0.0002) and HDL (r = 0.96; P < 0.0008) in total plasma supplemented with the carboxylated compound. It is concluded that 13-cis-retinoic acid can upregulate the CETP-mediated cholesteryl ester transfer reaction both in reconstituted mixtures containing isolated lipoproteins and purified CETP, and in total normolipidemic human plasma.

RESUMO

The populations of Morocco, Algeria, and Tunisia are composed of different ethnic groups including Arabs, Berbers, Sub-Saharan Africans, Europeans, and Turks. Between 1981 and 1991, we studied more than 3,000 individuals from these North African countries. One-hundred and eighty-one carried one (or more) unusual hemoglobin variant(s) other than Hb S and Hb C which are the most frequent variants in these countries. Each of these 181 individuals was heterozygous for at least one of the 49 abnormal alpha or beta alleles identified by electrophoretic and/or structural studies, and some homozygotes were detected. A few mutants are common in North Africa: Hb O-Arab, Hb D-Punjab and Hb G-Philadelphia. Other mutants encountered in European or African populations are found in relatively few North African families. The observed polymorphisms in the populations of North Africa probably result largely from their complex ethnic origins.

RESUMO

A chromatographic method is described to determine the distribution of selenium between selenoprotein P, glutathione peroxidase (GSH-Px), and albumin in plasma, using two small columns of heparin-Sepharose and reactive blue 2-Sepharose linked together in tandem. One milliliter of plasma was diluted to 12 ml with 0.02 M sodium phosphate buffer, pH 7.0 (the equilibration buffer), applied to the heparin-Sepharose column, and eluted at a flow rate of 30 ml per hour. GSH-Px was not retained by either of these columns but selenoprotein P was retained by heparin-Sepharose and albumin by reactive blue. After the two columns were separated, selenoprotein P was eluted with heparin from heparin-Sepharose and albumin eluted from reactive blue with high salt. Analytical work confirmed the presence of selenoprotein P, GSH-Px, and albumin in the respective fractions. When rats were injected with 75Se as either selenite or selenomethionine most of the radioactivity was incorporated into the selenoprotein P fraction, with the next greatest amount into GSH-Px, and the least amount into albumin. Slab gel electrophoresis was used to determine that most of the selenium in each of the three fractions was associated with each of these selenium containing proteins. This method indicated that the majority of the selenium in plasma is associated with selenoprotein P, and the only time this was found not to be true was with high levels of dietary selenomethionine.

RESUMO

Blood samples from 1,000 subjects, 2-80 years old, were tested to explore the prevalence of alpha-thalassemia trait, high persistent HbF (HPFH), sickle cell trait and beta-thalassemia minor in northern Jordan. Hematological parameters and hemoglobin electrophoresis were carried out on all samples. Results showed 10 (1%) subjects were sickle cell trait, 35 (3.5%) were heterozygous beta thalassemia, 31 (3.1%) alpha thalassemia trait and 10 (1%) high persistent HbF. The prevalence rates were different from those reported in neighbouring countries and their significance is discussed. No other abnormal hemoglobin types were observed.

RESUMO

The effect of gossypol content of cottonseed cake given as a source of CP in lamb (n = 8) rations was examined on the following blood parameters: plasma total protein, albumin, globulins, urea, glucose, hematocrit, hemoglobin, and mean corpuscular hemoglobin concentrations. The diets were isonitrogenous and isocaloric and contained 0, 15, and 30% cottonseed cake for 62 d. Blood samples were taken at the beginning, middle, and end of the experiment. Plasma total protein and globulins were higher at d 30 of the experimental period, but plasma albumin concentration, hematocrit, and hemoglobin were higher at the beginning of the experiment; plasma urea concentration was higher at d 60, and plasma glucose concentration was lower at d 30 of the experiment. The highest fraction in all treatments was albumin, followed by alpha 2-globulin and beta-globulin fractions, and there was no gamma 1-globulin fraction at d 30 and 60 of the experimental period. Liver examination showed significant differences in free gossypol content and accumulation, total N, and total protein percentage among the three treatments. Gossypol toxicity was not observed. The absence of gossypol toxicity in these animals has been attributed to detoxification of free gossypol by the formation of gossypol-protein complex in the rumen.

RESUMO

It could be identified 43 antigens of mugwort pollen (Artemisia vulgaris), 31 migrating anodically and 12 cathodically, by means of crossed immunoelectrophoresis (CIE). Eleven antigens bound human IgE-antibodies in crossed radioimmunoelectrophoresis (CRIE). Two major allergens could be found, allergens 23 and 40.- The allergenic activity of mugwort pollen extract was examined by means of RAST-inhibition. Specificity of this reaction could be determined by a control trial with grass pollen extract.

RESUMO

Fourteen pregnant women with sickle cell disease (11 SS and 3 SC) were randomized into two groups to receive routine antenatal supplementation either with ferrous gluconate or with placebo tablets. Their hemoglobin levels and bone marrow iron content were determined prenatally and 6 weeks post partum. The fetal weights and the incidence of pain crisis in both groups were recorded. Using an iron content grading from 0 to 5, no marrow of any subject showed iron depletion. The placebo group showed an aggregate postnatal loss of 4 grades of iron repletion while the iron supplemented group showed an aggregate gain of 2 grades. There were no significant differences between the birth weight or the incidence of pain crises in both groups. We conclude that routine iron supplementation is not justified in pregnant women with sickle cell disease, as it would tend to increase already adequate or excessive iron body stores. We recommend that a clear need for iron should be established before iron supplementation is prescribed to them.

RESUMO

It has been suggested that extracts of feverfew may inhibit platelet behaviour via effects on platelet sulphydryl groups. In the present study we have obtained evidence for such a mode of action. Compounds that contain sulphydryl groups such as cysteine and N-(2-mercaptopropionyl)glycine prevented the inhibition of platelet behaviour by feverfew. Feverfew and parthenolide (one of the active components of feverfew) dramatically reduced the number of acid-soluble sulphydryl groups in platelets. This effect occurred at concentrations similar to those that inhibited platelet secretory activity. Feverfew itself did not induce the formation of disulphide-linked protein polymers in platelets but polymer formation occurred when aggregating agents were added to feverfew-treated platelets. Feverfew evoked changes in the metabolism of arachidonic acid that were similar to those observed in glutathione-depleted platelets.
