Bernd Grohe
Peptides descended from the salivary proteins statherin and histatin were recently identified in saliva and the acquired enamel pellicle (AEP), a proteomic layer coated on enamel. In particular, the statherin phosphopeptide DpSpSEEKFLR (DSS) was found to adsorb to enamel-like hydroxyapatite and inhibit plaque-related crystal formation. To determine the mechanism of these processes, we studied peptide-crystal interactions based on the sequences DSS and RKFHEKHHSHRGYR (RKF). The latter is a basic histatin sequence showing antimicrobial effects...

Ethernet-AVB/TSN (Audio Video Bridging/Time-Sensitive Networking) and AFDX (Avionics Full DupleX switched Ethernet) are switched Ethernet technologies, which are both candidates for real-time communication in the context of transportation systems. AFDX implements a fixed priority scheduling strategy with two priority levels. Ethernet-AVB/TSN supports a similar fixed priority scheduling with an additional Credit-Based Shaper (CBS) mechanism. Besides, TSN can support time-triggered scheduling strategy. One direct effect of CBS mechanism is to increase the delay of its flows while decreasing the delay of other priority ones...

REVIEW
Eliyahu Mass
The oro-dento-facial features and dysfunctions of children with hereditary sensory and autonomic neuropathy type III (HSAN III), known as familial dysautonomia (FD) or Riley-Day syndrome, were first described in the scientific literature in 1949. They include: dental trauma, dental and soft tissue selfmutilation, normal dental age, normal sequence and timing of eruption and exfoliation of teeth, smaller tooth size, different and disproportional tooth components, normal alveolar bone height, small jaws, mild crowding and malocclusion...

Uri Zilberman
Down syndrome presents dentists with several treatment problems due to hereditary olygodontia of permanent teeth, abnormal development of the midface causing small maxilla and class III occlusion, abnormal mineralization of teeth, reduced bone density and hypotony. The challenge of replacing missing permanent teeth was the trigger for the development of dental implants some 30 years ago. However, the abnormal development of jaw bones and the reverse occlusion caused concerns in the dental community regarding the possibility of using dental implants in Down syndrome patients...

In the context of concerns about American youths' failure to take advanced math and science (MS) courses in high school, we examined mothers' communication with their adolescent about taking MS courses. At ninth grade, U.S. mothers (n = 130) were interviewed about their responses to hypothetical questions from their adolescent about the usefulness of algebra, geometry, calculus, biology, chemistry, and physics. Responses were coded for elaboration and making personal connections to the adolescent. The number of science, technology, engineering, and mathematics courses taken in 12th grade was obtained from school records...

INTRODUCTION: Early data support the use of medical expulsive therapy (MET) in children. However, little is known regarding use or outcomes associated with MET outside of pediatric-specific practices. Using a national administrative dataset, we sought to characterize utilization patterns of MET as well as assess outcomes associated with MET exposure. STUDY DESIGN: We interrogated the MarketScan Commercial Claims and Encounters database to identify children under the age of 18 presenting to the emergency department (ED) with any diagnosis of upper urinary tract calculi (UUTC, including renal and ureteral calculi)...

BACKGROUND: In the literature, many studies were attempted to analyze the distribution of oral reactive lesions in terms of age, gender and location. However, very few studies have focused on the detailed histopathological features of these reactive lesions of oral cavity. Thus, the purpose of this paper is to document the occurrence, distribution and various histopathological features of reactive gingival lesions. MATERIALS AND METHODS: This study is a retrospective archival review of reactive gingival lesions of oral cavity such as irritational fibroma (IF), inflammatory gingival hyperplasia (IGF), pyogenic granuloma (PG), peripheral giant cell granuloma (PGCG) and peripheral ossifying fibroma involving gingival tissues...

Inadvertent spillage of gall stones is a rare yet important cause of delayed postcholecystectomy complications. Varied presentations and difficulty in diagnosis are the hallmarks, making it crucial to have a high index of suspicion to detect and intervene appropriately. Peritoneo-cutaneous fistulae from the retained stone can be completely excised in toto.

Silicate urolithiasis is rare in humans (0.2%) but common in herbivorous animals. We report a previously unreported instance in India where a pediatric patient with renal pelvic calculus who underwent percutaneous nephrolithotomy was found to have silicate urolithiasis on stone analysis. Retrospective analysis did not reveal any risk factors associated with silicate stone formation.

Jian Liu, Kexin Liu, Shutang Liu
In this paper, adaptive control is extended from real space to complex space, resulting in a new control scheme for a class of n-dimensional time-dependent strict-feedback complex-variable chaotic (hyperchaotic) systems (CVCSs) in the presence of uncertain complex parameters and perturbations, which has not been previously reported in the literature. In detail, we have developed a unified framework for designing the adaptive complex scalar controller to ensure this type of CVCSs asymptotically stable and for selecting complex update laws to estimate unknown complex parameters...
