Abstract
BACKGROUND Diabetes mellitus (DM) is a major risk factor for coronary artery disease, renal failure, retinopathy, and neuropathy. Over the last years, there has been an increasing demand in folk medicine for natural sources that could help in the treatment of chronic diseases, including diabetes. The rind of passion fruit (Passiflora edulis f. Flavicarpa) is traditionally used as a functional food due to its high concentration of soluble and insoluble fiber. OBJECTIVE The aim of this study was to determine the effect of high-fiber diet albedo of passion fruit on the metabolic and biochemical profile in diabetic rats induced by alloxan (2%). DESIGN The passion fruit mesocarp fiber was dried in an oven with circulating air at 60°C and pulverized. We used 32 adult male rats, divided into 4 groups: Wistar group 1 control (GC), Wistar group 2, 15% fiber (GF15), Wistar group 3, 30% fiber (GF30), Wistar group 4, fiber disolved in water (GFH2O). The ratio of passion fruit was prepared according to the AIN 93M guidelines, varying only the source of dietary fiber. The corresponding diet for each group was offered to the animals for 60 days. RESULTS There was a statically significant decrease in plasma glucose for GFH2O, GF15%, and GF30% groups with 27.0%, 37.4%, and 40.2%, respectively. CONCLUSION The use of mesocarp fiber of passion fruit at concentrations of 15% and 30% are an important dietary supplement for the treatment of DM due to its potential hypoglycemic effect, and its ability to reduce triglycerides and VLDL-cholesterol levels with a principal reduction of insulin and leptin.

Abstract
We tested whether the fish Nile tilapia (Oreochromis niloticus) in a monosex male group spends more energy and displays an agonistic profile, differently from males in male-female groups. Such differences are expected because males and females should compete for different reproductive resources. An intruder male (MM) or female (MF) was paired with a resident male and agonistic interaction was quantified during 20 minutes, 10 minutes after pairing and another 10 minutes period 30 minutes later. Energetic cost was evaluated from O2 consumption, determined by Winckler's Method after 40 minutes pairing. Latency for fighting (mean +/- SD, MM = 27.40 +/- 25.15 s; MF = 14.22 +/- 21.19 s; Mann-Whitney test, U = 33.50, P = 0.21) and frequency of the all agonistic acts in the first 10 minutes session (mean +/- SD, MM < 72.30 +/- 25.29; MF < 73.50 +/- 21.65.10/min; Mann-Whitney test, P > 0.10) were not affected by group composition, thus suggesting that each intruder was a potential competitor at the beginning of the agonistic interaction. However, frequency of undulation (a behavior displayed also during courtship) was higher in the MF than in the MM resident fish (mean +/- SD, MM = 3.56 +/- 5.89; MF = 8.56 +/- 4.00.10/min; Mann-Whitney test, U = 15.50, P = 0.01) at the end of the 10 min session. Frequency of flight, however, was lower in MF than in MM intruder (mean +/- SD, MM = 3.90 +/- 4.33; MF = 0.44 +/- 0.96.10/min; Mann-Whitney test, U = 23.50, P = 0.04). Moreover, the agonistic profile in MM groups was composed of more types than in MF groups (less fighting types were exhibited by both resident and intruder fish). Despite the behavioral differences, energy cost in terms of O2 consumption was not affected by group composition (mean +/- SD, MM = 1.93 +/- 0.54; MF = 1.77 +/- 0.46 mgO2 x gDW(-1) x 40/min; Student's t independent test, t = 0.71, P = 0.49).

Abstract
A tandem fusion involving chromosome 4 and chromosome 21 of the bovine karyotype, is described in a newborn Holstein-Friesian heifer which was also a blood chimera exhibiting female cells of normal bovine karyotype and male cells with a 59, XY + tan (4:21). The rearranged chromosome was a dicentric and the longest acrocentric in the male cells. Apart from the features characteristic of the freemartin condition, no other phenotypic abnormalities were detected in the heifer calf. Since the heifer and other calves of the herd were not eartagged at birth, 20 newborn bull calves of the same age in the herd were analyzed in an attempt to identify the male born co-twin to the heifer. However, this effort proved unsuccessful, probably because the co-twin had died in utero or was erroneously included among the calves sent to the slaughter house.
