Baybean ( Canavalia rosea (Sw.) DC.); organogenesis, morphological and anatomical studies Gayana Botánica
Mohajer,Sadegh; Taha,Rosna Mat; Mohamed,Normadiha; Razak,Ummi Nur Abdul.
ABSTRACT Morphological and anatomical studies comprised leaf venation, histological analysis and epidermal peeling were carried out on Canavalia rosea (Sw.) DC.). Anatomical studies of the leaf and root determined the presence of cuticle and oil glands, arrangement of cells and the structure of vascular system. The dorsiventral leaf with pinnate venation and amphistomatic leaf with paracytic type stomata were embedded below the epidermis. Trichomes and oil glands were also observed on both adaxial and abaxial surfaces of leaf. Longitudinal sections of the callus showed the existence of meristematic cells, which could give rise to plant regeneration. In the process of organogenesis, adventitious shoots emerged from leaf and stem explants within 2 months...

Correlation between sperm characteristics and testosterone in bovine seminal plasma by direct radioimmunoassay R. Bras. Zootec.
Souza,Luiz Waldemar de Oliveira; Andrade,André Furugen Cesar; Celeghini,Eneiva Carla Carvalho; Negrão,João Alberto; Arruda,Rubens Paes de.
The objectives of this study were to validate a non-extractive RIA for seminal testosterone and quantify the hormone using a solid-phase commercial kit, and study the correlation between testosterone in seminal plasma and sperm characteristics. Parallelism showed a correlation index r = 0.992 (Y = -5.47 + 1.073X; R² = 0.985), indicating that the non-extractive method presented is indicated particularly for assessment of testosterone when establishing comparisons between samples. Overall mean (±SD) of testosterone level was 0.60±0.65 ng/mL. Correlation was only found between the seminal concentrations of testosterone and pH of the semen.

Wang,Y; Li,YB; Yang,HM; Wang,ZY.
ABSTRACT We investigated the egg production, changes in luteinizing hormone (LH), follicle-stimulating hormone (FSH), gonadal hormones, and their mRNA levels in the hypothalamic-pituitary-gonadal axis of White King pigeons submitted to different photoperiods. The treatments consisted of three photoperiods (8 h light (L):16 h dark (D), 12L:12D, and 16L:8D), with three replicates of twelve pairs of adult pigeons. The birds were exposed the photoperiods for 45 days. Egg production performance was recorded daily. Six pigeon pairs per replicate were selected for plasma collection, and six pigeon pairs per replicate for the resection of the hypothalamic-pituitary-gonadal (HPG) axis. Egg production was significantly improved by long-day lighting (16L:8D), while...

Effects of insulin and actin on phosphofructokinase activity and cellular distribution in skeletal muscle Anais da ABC (AABC)
Silva,Ana Paula P.; Alves,Gutemberg G.; Araújo,Alexandre H.B.; Sola-Penna,Mauro.
In this work, we report evidences that the association of phosphofructokinase and F-actin can be affected by insulin stimulation in rabbit skeletal muscle homogenates and that this association can be a mechanism of phos-phofructokinase regulation. Through co-sedimentation techniques, we observed that on insulin-stimulated tissues, approximately 70% of phosphofructokinase activity is co-located in an actin-enriched fraction, against 28% in control. This phenomenon is accompanied by a 100% increase in specific phosphofructokinase activity in stimulated homogenates. Purified F-actin causes an increase of 230% in phosphofructokinase activity and alters its kinetic parameters. The presence of F-actin increases the affinity of phosphofructokinase for fructose...

Evaluation of thyroxine (T4) and progesterone-17-alpha-OH circadian rhythm in swine females (Sus scrofa domestica - Linnaeus, 1758) Braz. J. Vet. Res. Anim. Sci.
TONIOLLO,Gilson Hélio; VICENTE,Wilter Ricardo Russiano; OLIVEIRA,Claudio Alvarenga de; CIPPOLA NETO,José.
Aiming at the evaluation of the occurrence of thyroxine and progesterone-17-alpha-OH circadian rhythm, 4 adult crossbred swine females (non-pregnant and showing no estrous signs) were studied, reared and kept under a industrial management system. Hormone determinations were assessed by solid phase radioimmunoassay (RIA)ª. Thyroxine serum analysis showed the highest concentrations around 3:00 PM and decreased until reaching the lowest values at the 0:00 to 4:00 AM interval. Regarding progesterone-17-alpha-OH, the highest concentrations were observed at 3:00 AM, showing a progressive decrease along the day until reaching lower values at the 12:00 to 3:00 PM interval.

Heat identification by 17β-estradiol and progesterone quantification in individual raw milk samples by enzyme immunoassay Electron. J. Biotechnol.
Domènech,Anna; Pich,Sara; Arís,Anna; Plasencia,Carmen; Bach,Alex; Serrano,Alicia.
Background: There is a substantial decline in first-service-pregnancy-rate in dairy cows. In this regard, future prospects are to measure milk hormones on-farm and progesterone levels in milk are not enough to precise ovulation unless connected to other data. The objectives of this study were to investigate whether 17β-estradiol could be measured from individual cow milk samples using a commercially available non-radiolabelled enzyme immunoassay kit (EIA) with no previously reported milk application, and whether those detections could precisely illustrate 17β-estradiol pre-ovulation peak in spite of its limited concentration and short manifestation in milk. Results: Milk sample treatments for progesterone and 17β-estradiol EIA...

Influence of fermented fish meal supplementation on growth performance, blood metabolites, and fecal microflora of weaning pigs R. Bras. Zootec.
Lee,Hyuk Jun; Choi,In Hag; Kim,Dong Hyeon; Joo,Young Ho; Kim,Sam Churl.
ABSTRACT This study was conducted to estimate the effect of dietary supplementation with fermented fish meal on growth performance, blood metabolites, and fecal microflora in weaning pigs. A total of 180 weaned pigs ((Landrace ×Yorkshire) × Duroc; with average body weight of 6.0 kg) were randomly distributed among three dietary treatments (0, 0.2, and 0.5% fermented fish meal) in three replicate pens (20 heads per pen) in a completely randomized trial over three weeks. Addition of fermented fish meal to weanling pig diets had a linear effect on average feed intake and a quadratic trend on final body weight, average daily gain, and gain:feed ratio throughout the whole period (but not initial body weight). Hematocrit, monocyte, immunoglobulin G, and blood...
