BACKGROUND: Stromal vascular fraction (SVF) can easily be obtained from a mini-lipoaspirate procedure of fat tissue and platelet rich plasma (PRP) can be obtained from peripheral blood. The SVF contains a mixture of cells including ADSCs and growth factors and has been depleted of the adipocyte (fat cell) population. We evaluated the safety and efficacy of administering SVF and PRP intra-discally into patients with degenerative disc disease. METHODS: A total of 15 patients underwent a local tumescent liposuction procedure to remove approximately 60 ml of fat tissue...

Malocclusions with anterior crossbite are a major esthetic and functional concern for patients. This case report presents a 27-year-old Syrian female who was diagnosed with a class 3 malocclusion, combined with anterior crossbite, deep bite, concave profile, and inadequate maxillary incisor exposure. There was a centric occlusion (CO)/centric relation (CR) discrepancy and the mandible could be manipulated to near edge-to-edge incisal relation. Correction was done by class 3 intermaxillary elastics on upper and lower mini-implants for the first 6 months, followed by preadjusted edgewise appliance...

INTRODUCTION: Primary stability is essential to the success of orthodontic mini-implants (OMIs) and heavily depends on the mechanical retention between OMIs and their supporting bone. Alveolar cortical bone commonly serves as the supporting bone for OMIs during treatment. The purposes of this study were to characterize alveolar cortical bone thickness and density in the maxilla and to explore patient factors that may significantly affect these bone properties. METHODS: Sixty medical computed tomography scans of the maxilla were analyzed from a selected sample of patients seen at the Radiology Department of Boston Children's Hospital...

A cesarean scar ectopic pregnancy (CSEP) is a fairly uncommon presentation wherein the conceptus is implanted deep in the myometrium and at the exact scar site of the previous cesarean section. There are various CSEP management options that range from medical treatment to surgical interventions such as dilatation and curettage, laparoscopic excision, resection by laparotomy, or, sometimes, a combination of these modalities. Establishing a diagnosis of CSEP can be challenging. Given the relatively rare incidence of CSEP, its management is controversial and current standards of therapy have been derived from data obtained from a limited number of patients...

This study aimed to develop a new biodegradable stent for peripheral artery disease (PAD) that could provide sufficient radial force to maintain long-term patency and flexibility. All self-expandable hybrid biodegradable stents were designed by using a knitting structure composed of poly-L-lactic acid (PLLA) and nitinol. Four different types of stents were implanted in 20 iliac arteries in 10 mini pigs as follows: a bare-metal stent (BMS) (group 1, n = 5), a drug-free hybrid stent (group 2, n = 5), a 50% (50 : 100, w/w) paclitaxel (PTX)/poly-lactide-co-glycolic acid (PLGA; fast PTX-releasing form) hybrid stent (group 3, n = 5), and a 30% (30 : 100, w/w) PTX/PLGA (slow PTX-releasing form) hybrid stent (group 4, n = 5)...

BACKGROUND: Numerous environmental and genetic factors can contribute significantly to behavioral and cardiorespiratory variability observed experimentally. Affordable technologies that allow for noninvasive home cage capture of physio-behavioral variables should enhance understanding of inter-animal variability including after experimental interventions. NEW METHOD: We assessed whether EPIC electric field sensors (Plessey Semiconductors) embedded within or attached externally to a rodent's home cage could accurately record respiration, heart rate, and motor behaviors...

Angelman syndrome (AS) is a rare neurogenetic disorder characterized by severe developmental delay, motor impairments, and epilepsy. GABAergic dysfunction is believed to contribute to many of the phenotypic deficits seen in AS. We hypothesized that restoration of inhibitory tone mediated by extrasynaptic GABAA receptors could provide therapeutic benefit. Here, we report that ganaxolone, a synthetic neurosteroid that acts as a positive allosteric modulator of synaptic and extrasynaptic GABAA receptors, was anxiolytic, anticonvulsant, and improved motor deficits in the Ube3a-deficient mouse model of AS when administered by implanted mini-pump for 3 days or 4 weeks...

BACKGROUND: Healthy ageing is accompanied by simultaneous decline of visual and neural function. Studies in animals and humans provide converging evidence that these functions' decrease is mostly associated with structural change in ocular and brain structure. We investigated whether regaining visual function after ocular reconstruction was associated with functional and structural changes in the brain. METHODS: We did a prospective controlled clinical trial including 21 consecutive typical ageing patients (42 eyes; mean age 63·14 years, SD 7·82) with decreased visual function and diagnosis of bilateral age-related cataracts requiring phacoemulsification surgery and multifocal or monofocal intraocular lens implantation...
