Natural killer (NK) cells are key components of the innate immune system with their killing and cytokine producing abilities. Bovine NK cells have been characterized as NKp46(+)/CD3(-) lymphocytes, but little is known about these cells in neonatal calves. As the newborn calf, with an insufficiently developed acquired immunity, has to employ the innate immune system, we wanted to investigate whe...

A 9-day-old term male neonate was referred to us with history of fever, lethargy, poor feeding and seizures. The neonate was delivered by elective caeserian section, and weighed 2.98 kg at birth. The mother was treated for undiagnosed febrile illness before the delivery which lasted for a week. On 6th day of life, the child was readmitted in view of poor feeding and fever. Septic workup was neg...

introduction:  premature neonates admitted in nicu besides being separated from their mothers are prone to inevitably painful and stressful situations. kangaroo care is the most effective method to get rid of this separation and its negative consequences. this study was performed to determine the experiences of mothers having premature neonates concerning kangaroo care.   material and methods: ...

Neonates deposit protein at a very high rate and efficiently utilize dietary amino acids for protein deposition. This high efficiency is associated with an elevated stimulation of tissue protein synthesis by feeding. Our recent studies have focused on identification of the factors that mediate this response in the neonate. A positive curvilinear relationship between skeletal muscle protein synt...

Whole neonate rabbit corneas and adult corneas containing 2-week-old scars were incubated in the presence of [14C] glycine. Radiolabeled collagen extracted from the corneas and scar tissue were analyzed by sodium dodecylsulfate/polyacrylamide gel electrophoresis and fluorography to determine the types and relative quantity of collagen polypeptides present and synthesized by these tissues. In ad...

Results of cerebrospinal fluid (CSF) examinations from 77 high-risk neonates were reviewed. The mean CSF white cells (WBC) count was 4.5 cell/mm3, being two standard deviations above the mean 11.7 cells/mm3 in the full-term gestation neonate group; in the premature neonate one, the mean CSF WBC count was 5.1 cells/mm3, being two standard deviations above the mean 16.7 cell/mm3. PMNs (polymorpho...

Sn(tin)-protoporphyrin, a potent competitive inhibitor of heme oxygenase, can suppress hyperbilirubinemia in animal neonates and significantly reduce plasma bilirubin levels in animals and man. To further explore the biological actions and metabolic disposition of Sn-protoporphyrin, we have examined its effect in the suckling neonate when administered to the mother either 24-48 h before or imme...

During pregnancy and lactation, mothers require significant amounts of calcium to pass on to the developing fetus and suckling neonate, respectively. Given the dependence of adult calcium concentrations and bone metabolism on vitamin D, one might anticipate that vitamin D sufficiency would be even more critical during pregnancy and lactation. However, maternal adaptations during pregnancy and l...

Environ. Entomol. 19(5): 1566-1571 (1990) ABSTRACT The dispersal and survival of neonate diamondback moth larvae, Plutella xylostella (L.), were measured on normal bloom susceptible 'Round-Up' cabbage and a resistant genotype descended from glossy cauliflower, PI 234599. During the first 24 h after hatching, neonate P. xylostella dispersed more rapidly and initiated fewer mines on the resistant...

Paradoxically, fear conditioning (odor-0.5 mA shock) yields a learned odor preference in the neonate, presumably due to a unique learning and memory circuit that does not include apparent amygdala participation. Post-training opioid antagonism with naltrexone (NTX) blocks consolidation of this odor preference and instead yields memory of a learned odor aversion. Here we characterize the neural ...
