Delayed cord clamping leads to the increased level of haematocrite and victocytes which is high risk of hyperbilirubinemia . This study is to determine if there is an effect of timing of cord clamping relating to the incidence of hyperbilirubinemia on newborn, and to create formulating the standard procedures in maternal interventions related to the timing of cord clamping, another objective is  preventing  interventions of its occurrence when the clamping is performed immediately after birth. Crossectional study was applied design of the research. Population and samples included infants spontaneus by healthy primigravidas.Two trials were included, 20 participants of each received interventions of cord clamping more than equalivalent 1 minute and less than 1 minute followed by bilirubin assessment 48 hours after birth, and analysed by using Linier Regression. There is no significant effect of timing of cord clamping on newborn with regard to hiperbilirubinemia, because the effect of the clamping on bilirubin level reaches up to 68.2%, while the other 31.8% of the varying levels are affected by other factors. There is a need to conduct other relevant studies aimed to prevent hyperbilirubinemia starting from antenatal to postnatal stage.; Key Words: Jaundice, Newborn, Hyperbilirubinemia, Time of Clamping, Primigravidas

This review covers the pre- and post-natal development of skeletal muscle of vertebrate animals with cellular and molecular levels. The formation of skeletal muscle initiates from paraxial mesoderm during embryogenesis of individuals which develops somites and subsequently forms dermomyotome derived myotome to give rise axial musculature. This process (myogenesis) includes stem and progenitor cell maintenance, lineage specification, and terminal differentiation to form myofibrils consequent muscle fibers which control muscle mass and its multiplication. The main factors of muscle growth are proliferation and differentiation of myogenic cells in prenatal stage and also the growth of satellite cells at postnatal stage. There is no net increase in the number of muscle fibers in vertebrate animals after hatch or birth except fish. The development of muscle is characterized by hyperplasia and hypertrophy in prenatal and postnatal stages of individuals, respectively, through Wnt signalling pathway including environment, nutrition, sex, feed, growth and myogenic regulatory factors. Therefore further studies could elucidate new growth related genes, markers and factors to enhance meat production and enrich knowledge on muscle growth.Asian J. Med. Biol. Res.

Cognitive deficiencies caused by maternal omega-3 PUFA deficiency (O-3 Def), are easier reversed when supplementation of DHA as phospholipids than triglycerides, especially during the late postnatal stage.

Improve Production Efficiency

Females from lines of mice divergently selected for post-weaning net feed intake maintained significant line differences in daily feed intake (0.8 g/day difference, 22%) and net feed intake (± 0.35 g/day respectively) both before and during pregnancy. Dam/litter units converged completely for daily feed intake immediately in the postnatal stage, during a period of negative energy balance when feed intake and rate of gain were both maximised. Feed intake net of that required for growth and maintenance of liveweight was effectively zero for both lines during this 2-week period. The lines re-diverged in late-lactation. Variance for all traits increased substantially over the 11�weeks of the experiment.In an extensive production environment, where peak lactation generally coincides with abundant pasture supply, this short convergence would have little impact on overall production efficiency. Consequently, selection for post-weaning net feed intake based on growth/weight components remains a potential means to improve production efficiency.

Cilia are microtubule-based hair-like organelles that extend from the cell surface. However, the existence and distribution of cilia in each organ and tissue at the postnatal stage in vivo remain largely unknown. In this study, we defined cilia distribution and arrangement and measured the ciliary lengths and the percentage of ciliated cells in different organs and tissues in vivo by using cilium dual reporter-expressing transgenic mice. Cilia were identified by the presence of ARL13B with an mCherry+ signal, and the cilium basal body was identified by the presence of Centrin2 with a GFP+ signal. Here, we provide in vivo evidence that chondrocytes and cells throughout bones have cilia. Most importantly, we reveal that: 1. primary cilia are present in hepatocytes; 2. no cilia but many centrioles are distributed on the apical cell surface in the gallbladder, intestine, and thyroid epithelia; 3. cilia on the cerebral cortex are well oriented, pointing to the center of the brain; 4. ARL13B+ inclusion is evident in the thyroid and islets of Langerhans; and 5. approximately 2% of cilia show irregular movement in nucleus pulposus extracellular fluid. This study reveals the existence and distribution of cilia and centrioles in different tissues and organs, and provides new insights for further comprehensive study of ciliary function in these organs and tissues.

AbstractMaternal-offspring bonding and maturation of maternal behavior is necessary during the early postnatal period of an infant to promote optimal development and growth. The regulation of maternal behavior is multifactorial relying both on sensory cues including auditory and olfactory signals emitted by the infant and received by the mother, as well as proper neuroendocrine responses including that of the oxytocin system. The intestinal microbiota has emerged as a critical regulator of growth and development in the early postnatal period of an individual’s life. While, this is best appreciated in the context of direct interactions between the microbiota and the infant, the microbiota can indirectly influence postnatal growth and development by regulating maternal factors. Here, we describe the identification of an intestinal E. coli strain that is pathogenic to the maternal-offspring system during the early postnatal stage of life and results in growth stunting of the offspring. However, rather than having a direct pathogenic effect on the infant, we found that this particular E. coli strain was pathogenic to the dams by interfering with the maturation of maternal behavior. The poor maternal behavior resulted in malnourishment of the pups and impaired IGF-1 signaling leading to the consequential stunted growth. Our work provides a new understanding of how the microbiota regulates postnatal growth and an additional variable that must be considered when studying the regulation of maternal behavior.
