37. Effect of CRABP2 on the proliferation and odontoblastic differentiation of hDPSCs
Abstract: Cellular retinoic acid-binding protein 2 (CRABP2) has been detected in several organs during embryonic development. Recent studies have demonstrated that CRABP2 plays important roles in the retinoic acid, β-catenin and Notch signaling pathways, as well as in the interaction between epithelial and mesenchymal cells, which are important for human de

38. Population biology of Macrobrachium jelskii (Miers, 1877) (Decapoda, Palaemonidae) from an artificial pond in Bahia, Brazil
Abstract The freshwater prawn Macrobrachium jelskii (Miers, 1877) is widely distributed in South America’s lentic and lotic habitats. We studied the population structure and reproductive biology of the species in the municipality of Cruz das Almas, state of Bahia, Brazil, to supply information on this ecologically and economically relevant species. Samples

39. Toxic Effects of Ochratoxin A on Calcium Metabolism during Chick Embryo Developmentand in Hatched Chicks
ABSTRACT The present study was carried out to study the effect of in-ovo ochratoxin A (OTA) injection in Highline layer eggs on calcium metabolism and blood biochemical parameters of embryos and after the hatch. At day 10 of embryonic development, one hundred and sixty-two fertile eggs were individually weighed and divided into two equal treatments. The firs

40. Differences between NMRI and DBA/2J mice in the development of somites and susceptibility to methylnitrosourea-induced skeleton anomalies
ABSTRACT The development of DBA/2J mouse strain embryos is nearly 12 h - or 6 somite pairs - delayed as compared to the outbred NMRI mouse embryos of the same age on gestation days (GD) 8-12. To evaluate inter-strain differences in susceptibility to teratogens, dams were treated with methylnitrosourea (MNU, 5 mg/kg body weight i.p.) on defined gestation days

41. EFFECT OF THERMAL STIMULATION IN EMBRYOS FROM COBB®GENETIC STRAIN UNDER COMMERCIAL SCALE
ABSTRACT Studies aimed at producing stronger birds and with better growth performance are being developed involving artificial incubation. To that extent, thermal stimulation by the heat of 1.39 ºC and 1ºC above the standard, and by cold of 36 ºC fixed, were applied in the last week of the embryonic development (day 14 to day 18) to Cobb® strain birds of

42. Fluoxetine effects on periodontogenesis: histomorphometrical and immunohistochemical analyses in rats
Abstract Reports have indicated that serotonin plays an important role in cell migration and differentiation during the organogenesis of several tissues, including the oral types. Administration of selective serotonin reuptake inhibitor (SSRI) drugs during pregnancy could affect the delivery of serotonin to embryonic tissues altering its development. Object

43. BPI-fold (BPIF) containing/plunc protein expression in human fetal major and minor salivary glands
Abstract The aim of this study was to determine expression, not previously described, of PLUNC (palate, lung, and nasal epithelium clone) (BPI-fold containing) proteins in major and minor salivary glands from very early fetal tissue to the end of the second trimester and thus gain further insight into the function of these proteins. Early fetal heads, and ma

44. POST-EMBRYONIC DEVELOPMENT OF INTRAMANDIBULAR GLANDS OF FRIESELLA SCHROTTKYI (FRIESE, 1900) (HYMENOPTERA: APIDAE) WORKERS
RESUMO As glândulas exócrinas desempenham importantes funções na organização social dos insetos, como a diferenciação de castas e inter-castas. Devido à sua plasticidade estrutural e funcional, estudos morfológicos destas glândulas contribuem para o melhor entendimento da biologia das abelhas sociais. Por isso, o objetivo deste estudo foi acompanh

45. Study on the Morphological Development of Quail Embryos
ABSTRACT In this study, the SWKQ series microcomputer automatic incubator was used to study the growth and development of quail in the embryonic stage. Results showed that the embryo shape of became gradually defined as embryo aged. On day 6, the head and body of quail were clearly differentiated, the legs became longer and the wings appeared. At 7 embryo ag

46. Thermal Manipulation Mid-term Broiler Chicken Embryogenesis: Effect on Muscle Growth Factors and Muscle Marker Genes
ABSTRACT Thermal manipulation (TM) during broiler chicken embryogenesis has been shown to promote muscle development and growth. However, the molecular bases of promoting broiler muscle development and growth are not fully understood. The aim of this study was to investigate the molecular bases of muscle growth and development in broiler chickens subjected t

47. Effect of Thermal Embryonic Manipulation on the Quality of Male and Female Broiler Meat Submitted to Thermal Stress Pre-Slaughter
ABSTRACT Adverse environmental conditions during rearing may negatively affect productivity and meat quality of the modern fast-growing broiler strains. Temperature manipulation during sensitive embryonic development periods may affect broilers' physiological responses to environmental conditions during rearing on commercial farms. The objective of this tria

48. The impact of eggshell colour and spot area in Japanese quails: I. eggshell temperature during incubation and hatching results
ABSTRACT This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica). Study material was allocated to five groups according to their eggshell and spot colours: black spots on greyish
