A review of the research on infant vagal tone suggests that vagal activity is associated with both infant growth and infant socioemotional development. Vagal activity has been noted to increase following the stimulation of pressure receptors as in massage therapy. Vagal activity, in turn, stimulates gastric motility which mediates weight gain in infants. Vagal activity has also been notably ele...
Quantification of skeletal data has been shown to be an effective and reliable method of demonstrating variation in human growth as well as for monitoring and interpreting growth. In South Africa as well as internationally, few researchers have assessed mandibular growth in late fetal period and early childhood and therefore standards for growth and age determination in these groups are limited...
The growth of 361 children with congenital hypothyroidism diagnosed by screening was assessed by estimating mean values for height, weight, body mass index (BMI), and head circumference on each birthday up to the age of 4 years. In the group of children with severe congenital hypothyroidism (pretreatment plasma thyroxine < or = 30 nmol/l), the mean heights at 1 and 2 years were less than standa...
Concerning the course cons t ruc t ion project "Engineer ing Design", a decision had to be made about the ins t ruct ional procedures of the seminar stage of the course. In order to come to this decis ion in a more just if iable way an exper iment was designed to compare four ins t ruct ional procedures (viz. a teacher-centred egruleg-, a s tudent-centred egruleg-, a teacher-centred ruleg-, and...
The ease and non-invasive nature of the procedure for drawing blood has made it possible to measure circulating tumor markers for cancer screening, diagnosis, follow-up and early detection of recurrence. Even though a tumor-specific marker has not yet been found, the specificity and sensitivity of currently used tumor markers have improved over the last several decades as they have progressed f...
Chondrosarcomas are uncommon tumors which originates in the head and neck and accounts for approximately 10 to 15% of all cases. Most chondrosarcomas exhibit an indolent growth pattern. Nasoseptal tumors may mimic common sinonasal conditions, making early diagnosis difficult. We report a case of nasoseptal metastatic chondrosarcoma which was atypical, characterized by an aggressive growth patte...
Successful treatment with human growth hormone (hGH) was initially reported by Raben in 19581. Although itis well established that pituitary derived or biosynthetic hGH increases the growth rate in growth hormone deficient children, many patients that were treated in the early days have not reached their target height, or attained adult height below the third percentile of population standards ...
Pan1p plays essential roles in both actin and endocytosis in yeast. It interacts with, and regulates the function of, multiple endocytic proteins and actin assembly machinery. Phosphorylation of Pan1p by the kinase Prk1p down-regulates its activity, resulting in disassembly of the endocytic vesicle coat complex and termination of vesicle-associated actin polymerization. In this study, we focus ...
Carcinogenesis is a multi-step process which result in uncontrolled cell growth. Mutations in DNA that lead to cancer disrupt these orderly processes by disrupting the programming regulating the processes.. This results in uncontrolled cell division leading to carcinogenesis. Oncogenes are genes whose protein products stimulate or enhance the division and viability of cells. Oncogenes arise by ...
Despite being mutated in cancer and RASopathies, the role of the activation segment (AS) has not been addressed for B-Raf signaling in vivo. Here, we generated a conditional knock-in mouse allowing the expression of the B-Raf(AVKA) mutant in which the AS phosphoacceptor sites T599 and S602 are replaced by alanine residues. Surprisingly, despite producing a kinase-impaired protein, the Braf(AVKA...
