Abstract: The sexual maturity, age at first maturation and fecundity in females of the yellow fish Girardinichthys multiradiatus were analyzed in the Huapango reservoir located in the State of Mexico, Mexico. From July 2007 to May 2008 bimonthly samplings were carried out and, using a bait well net, 407 individuals were collected (245 females and 162 males). Overall, the sex ratio between females/males was 1.51:1 (P <0.05). The age of first maturation in the females was 33 mm of standard length. The spawning period occurred in July and accounted for the highest values in the gonadosomatic index. For the fertility model only fertilized eggs and embryos were considered, and those were adjusted to the potential model F=1E-08L5.6144 (P <0.05). This study contributes to the understanding of the reproductive biology of the yellow fish, which takes place in the reservoirs of the State of Mexico.

Abstract: Biochemists and cell biologists, who are interested in membranes, tend to regard the human red blood cell ambivalently. On one hand, red blood cells lack nuclei and the various intracellular organelles, yet that are highly specialized for a particular respiratory function. On the other hand, the human red blood cell presents an excellent model for membrane transport function.

Abstract: Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) is a solitary parasitoid containing a great number of Diptera in the families Anthomyiidae, Calliphoridae, Muscidae, Tachinidae and Tephritidae. This species presents a diversified distribution and it has been found in North America, Canada and Africa The study determined the species of hosts of the parasitoid P. vindemmiae in cattle dung, human feces, manure kidneys, cattle liver, pig carcass, fish and fruit. The pupae were obtained by the flotation method. They were individually placed in gelatin capsules until the emergence of adult flies or their parasitoids. The overall percentage of parasitism was 6.8%. Through this study, knowledge of the bioecology and geographical distribution of parasitoids of dipterous in Brazil.

Abstract: Objective: The ultimate objective of this study is to help discern the epidemiological and clinical profile and factors associated with the risk of overweight and obesity, through a representative sample of a population, overweight, from a urban agglomeration located in east of Algeria. Methods: The present descriptive epidemiological study, realized on a representative sample of the adult population, of both sexes, aged 18 to 75 years, the city of Ain Fakroun, Thus, of the 64 districts of the municipality of Ain Fakroun, 12 urban districts are drawn. In each household 1-4 between 18 and 75 people were randomly. In total 273 households corresponding to a set of 1091 people surveyed. For recruiting, the anthropometric measurements are made, arterial pressions, blood samples are taken, anticoagulants in heparinized tubes, on fasting subjects, intended for a lipid profile and blood glucose. In addition, data collections were carried out through an interview. Results: The data results are shown that; more than 1/3 of the population is excess weight (BMI > 25 kg/m²). The prevalence increased significantly (p = 0.0014) among young adults and then gradually decreases with age and fall markedly among seniors over 60 years. The frequency of overweight patients is 36.41%; it is relatively identical in both sexes. However, the proportion of obese is predominant (60.98%) with obesity class I predominant in both sexes while severe obesity (BMI ≥ 40 kg/m²) is more common in women. The result on the association between BMI and vascular risk factors reinforce conventional notions. Conclusion: The descriptive point of view at men as well at women, the overweight seems due to social, biological and environmental factors.

Abstract: Larval zoeae of Brachyura were collected from five coastal systems located in the State of Veracruz, southwestern Gulf of Mexico. Some morphological differences among the zoeae families have been determined. Morphological analysis consisted of the following determinations: presence of rostral spines, dorsal and lateral, on the carapace; number of setae of the exopod, endopod, and protopod of the antenna; number of processes; shape and size of the somites of the abdomen; and the presence and number of spines on the furcae and inner margin of thetelson. A total of 92839 zoeae of Brachyura were obtained, and 14 families were identified: Aethridae, Calappidae, Portunidae, Menippidae, Panopeidae, Gecarcinidae, Grapsidae, Sesarmidae, Varunidae, Inachidae, Epialtidae, Pinnotheridae, Ocypodidae, and Ucididae. Morphological differences between these families include: Epialtidae and Inachidae lack lateral spines; Pinnotheridae lacks spines on one side of the carapace,and there may be a wing shape on the fifth abdominal somite; the exopod of the antenna is short in Grapsidae and well-developed in Ucididae; the fourth abdominal somite is significantly expanded in Ocypodidae; the family Gecarcinidae lacks spines on the furcae; Portunidae, Calappidae, and Aethridae have two or three spines on the furcae, but differ in the size of the exopod of the antenna relative to the size of the rostrum; and Sesarmidae and Varunidae differ in the lateral spines on the carapace. A key for identification of the zoeae to the family level is presented.This is the first key for Brachyura zoeae from the southwestern Gulf of Mexico.
