Haematological and biochemical reference intervals for farmed channel catfish

The reference intervals for biochemical variables and red blood cell indices of healthy intensively bred channel catfish Ictalurus punctatus were determined. The blood variables were determined using standardized clinical methods. The reference intervals (25th and 75th percentiles) were established using a non-parametric method. Reference intervals for plasma glucose, serum total protein, sodium, potassium, calcium, magnesium, chloride concentration, primary and secondary red blood cell indices were established. The haematological and biochemical reference intervals established may allow important clinical decisions about channel catfish.

Hydatidiform Mole in Ectopic Pregnancy Clinical, Imaging, Pathological and Immunohistochemical Characteristics

OBJECTIVE: To determine the clinical, pathological, immunohistochemical and imaging characteristics of hydatidiform mole in ectopic pregnancy (HMEP) in all the cases admitted to the Department of Obstetrics and Gynecology, University Hospital of Caracas (HUC), Central University of Venezuela.STUDY DESIGN: Retrospective and comparative study, based on clinical records review of 2 groups: 10 cases with a diagnosis of HMEP and 20 cases with intrauterine hydatidiform mole (IUHM) admitted to the Obstetrics and Gynecology Department of HUC from 1996 to 2010. Clinical, pathological, immunohistochemical and imaging features were analyzed.RESULTS: The prevalence of HMEP in this study was 0.14:1,000 pregnancies; in this group the mean age was 28.8 years, and the mean gestational age at admission was 8.6 weeks. Both groups (HMEP and IUHM) were comparable in these last variables. Abdominal pain and genital bleeding were the most common clinical symptoms in the HMEP group, while it was vaginal bleeding in the IUHM group. Ultrasound findings were similar to those traditionally described in nonmolar ectopic pregnancy. Histology and immunohistochemistry showed that all cases of HMEP were partial mole.CONCLUSION: Although in this study the prevalence of HMEP was high, the size of the sample limits definitive conclusions. This study concludes that all cases of HMEP are partial mole. (J Reprod Med 2012;57:329-332)

Evaluation of cytologic and biochemical variables in blood, plasma, and peritoneal fluid from calves before and after umbilical herniorrhaphy

Objective-To establish reference intervals for cytologic and biochemical variables in peritoneal fluid, whole blood, and plasma in calves with congenital umbilical hernias (CUHs) before and after herniorrhaphy and to assess whether those variables in calves with CUHs were altered, compared with findings in clinically normal calves.Animals-20 Holstein calves with or without a CUH.Procedures-10 calves with CUHs underwent herniorrhaphy. Blood and peritoneal fluid samples from all 20 calves were collected for cytologic and biochemical analyses on days 0 (before surgery), 1, 3, 5, 7, and 15. Data from the 2 groups were compared.Results-Reference intervals for the variables of interest were established for each group, Before surgery, calves with CUHs had significantly greater plasma total protein concentration and creatine kinase (CK) and aspartate aminotransferase activities and peritoneal fluid specific gravity values, compared with values for calves without CUHs. At various time points after surgery, peritoneal fluid total protein concentration; fibrinogen concentration; nucleated cell, polymorphonuclear cell, and lymphocyte counts; specific gravity; and lactate dehydrogenase, aspartate aminotransferase, and CK activities in calves with CUHs were significantly different from values in calves without CUHs. Some plasma and blood variables leg, total protein concentration, neutrophil count, and CK activity were significantly different between the 2 groups.Conclusions and Clinical Relevance-Values of certain cytologic and biochemical variables in peritoneal fluid, blood, and plasma were different between calves with and without CUHs. Thus, determination of reference intervals for these variables is important for interpreting diagnostic test results in calves with CUHs. (Am J Vet Res 2009;70:423-432)

Morphological and biochemical analysis of the stored and larval food of an obligate necrophagous bee, Trigona hypogea

Trigona hypogea, T. crassipes, and T. necrophaga are obligate necrophagous bees that differ from the majority of bees by using animal material instead of pollen as a protein resource. Since T. hypogea does not store protein in cerumen pots, it was thought that glandular secretions were its only larval protein source. This is in contrast to T. necrophaga which stores a yellowish proteinaceous jelly in the pots. Our results show that the larval food of T. hypogea has a higher protein content than the food stored in the pots and that it presents an electrophoretical protein pattern similar to that of the hypopharyngeal gland, indicating that workers add glandular secretions to the larval food while provisioning the brood cells. Thus, it can be suggested that T. hypogea has a provisioning behavior similar to other Meliponinae. The presence of several bands of proteins in the food stored in the pots shows that this species stores carrion mixed with honey in storage pots. Morphological data suggest that both larvae and adults make use of the same foodstuffs. These results also suggest that T. hypogea is more similar to other necrophagous species than it is to T. necrophaga (a more specialized bee).

The Association between Skipping Breakfast and Biochemical Variables in Sedentary Obese Children and Adolescents

Objective To investigate the relationship between skipping meals and biochemical variables in obese children and adolescents.Study design The sample was composed of 174 obese children and adolescents, aged between 6 and 16 years (80 male and 94 female). Body composition was assessed by dual-energy x-ray absorptiometry, fasting blood glucose, and lipid profile were measured after 12 hours fasting. The frequency of skipping breakfast, lunch, or dinner was assessed through a face-to-face interview carried out with the parents.Results The prevalence of eating breakfast daily was low in boys (47.5%) and girls (44.7%). A higher frequency of eating breakfast was negatively correlated with glucose (r = -0.16; P = .026), triglycerides (r = -0.19; P = .011), and very low density lipoprotein cholesterol (r = -0.21; P = .005). In the multivariate model, the weekly frequency of eating breakfast remained negatively associated with glucose (beta = -0.975; P = .017), triglycerides (beta = -7.792; P = .017), and very low density lipoprotein cholesterol (beta = -1.870; P = .009) independent of age, sex, trunk fatness, and parents' education.Conclusion Skipping meals, mainly breakfast, is associated with glucose and lipid levels in obese children and adolescents.

Acerola: importance, culture conditions, production and biochemical aspects

Origin and importance. Acerola, or Malpighia emarginata D. C., is native to the Caribbean islands, Central America and the Amazonian region. More recently, it has been introduced in subtropical areas (Asia, India and South America). The vitamin C produced by acerola is better absorbed by the human organism than synthetic ascorbic acid. Exportation of acerola crops is a potential alternative source of income in agricultural businesses. In Brazil, the commercial farming of acerola is quite recent. Climatic conditions. Acerola is a rustic plant. It can resist temperatures close to 0 degrees C, but it is well adapted to temperatures around 26 degrees C with rainfall between (1200 and 1600) mm per year. Fruit characteristics. Acerola fruit is drupaceous, whose form can vary from round to conic. When ripe, it can be red, purple or yellow. The fruit weight varies between (3 and 16) g. Maturation. Acerola fruit presents fast metabolic activity and its maturation occurs rapidly. When commercialised in ambient conditions, it requires fast transportation or the use of refrigerated containers to retard its respiration and metabolism partially. Production and productivity. Flowering and fruiting are typically in cycles associated with rain. Usually, they take place in 25-day cycles, up to 8 times per year. The plant can be propagated by cuttings, grafting or seedlings. Harvest. Fruits produced for markets needs to be harvested at its optimal maturation stage. For distant markets, they need to be packed in boxes and piled up in low layers; transportation should be done in refrigerated trucks in relatively high humid conditions. Biochemical constituents. Acerola is the most important natural source of vitamin C [(1000 to 4500) mg.100(-1) g of pulp], but it is also rich in pectin and pectolytic enzymes, carotenoids, plant fibre, vitamin B, thiamin, riboflavin, niacin, proteins and mineral salts. It has also shown active anti-fungal properties. Products and market. Acerola is used in the production of juice, soft drinks, gums and liqueurs. The USA and Europe are great potential markets. In Europe, acerola extracts are used to enrich pear or apple juices. In the USA, they are used in the pharmaceutical industry. Conclusions. The demand for acerola has increased significantly in recent years because of the relevance of vitamin C in human health, coupled with the use of ascorbic acid as an antioxidant in food and feed. Acerola fruit contains other significant components, which are likely to lead to a further increase in its production and trade all over the world.
