D S Zaghlool, R W Franz, J Jenkins
The use of ultrasound waves in conjunction with local thrombolysis may accelerate clot resolution and serve as an important therapeutic adjunct in the treatment of venous occlusive disease. Our goal was to provide a larger sample population over a 5-year period to evaluate our experience with the EkoSonic endovascular system (EKOS, EKOS Corporation, Bothell, WA). We suspected that ultrasound-accelerated thrombolysis (UAT) using EKOS would provide excellent thrombolysis and midterm patency rates with minimal thrombolytic complications...

STUDY OBJECTIVES: In mammals, there is evidence that glutamate has a role as a wake active neurotransmitter. So using video-based analysis of Drosophila behavior we undertook a study to examine if glutamate, which has been previously shown to have an excitatory role in neuromuscular junctions in Drosophila, may have a conserved wake-active role in the adult brain. METHODS: Using 6-9 day old female flies we examined the effect of perturbations of the glutamatergic signaling on total wakefulness and wake bout architecture...

In heterogeneous wireless networks, wireless local area network (WLAN) is highly preferred by mobile terminals (MTs) owing to its high transmission bandwidth and low access cost. However, in high-speed environment, handover from a cellular network to a WLAN cell will lead to a high number of handover failures and unnecessary handovers due to the WLAN coverage limitation and will become worse at high speed. A new vertical handover method is proposed to minimize the probability of handover failure and unnecessary handover while maximizing the usage of WLAN in high-speed environment...

Mammalian target of rapamycin (mTOR), a regulator of growth in many tissues, mediates its activity through two multiprotein complexes, mTORC1 or mTORC2. The role of mTOR signalling in skin morphogenesis and epidermal development is unknown. Here we identify mTOR as an essential regulator in skin morphogenesis by epidermis-specific deletion of Mtor in mice (mTOR(EKO)). mTOR(EKO) mutants are viable, but die shortly after birth due to deficits primarily during the early epidermal differentiation programme and lack of a protective barrier development...

INTRODUCTION: Sensorineural emergencies (SNE) are rare clinical situations. Few patients consult early explaining subsequent difficulty in having accurate data and management. Three clinical conditions are considered SNE in otolaryngology; they include sudden sensorineural hearing loss (SSHL), Bell's palsy and acute vertigo. There is very little data available on sensorineural emergencies in our setting. The aim of this study was to provide preliminary data on the management of Ear Nose and Throat (ENT) sensorineural emergency cases in Yaoundé Reference Hospital...

We present the data from a crowdsourced project seeking to replicate findings in independent laboratories before (rather than after) they are published. In this Pre-Publication Independent Replication (PPIR) initiative, 25 research groups attempted to replicate 10 moral judgment effects from a single laboratory's research pipeline of unpublished findings. The 10 effects were investigated using online/lab surveys containing psychological manipulations (vignettes) followed by questionnaires. Results revealed a mix of reliable, unreliable, and culturally moderated findings...

BACKGROUND: Interventional strategies for massive and submassive Pulmonary Embolism (smPE) have historically included either systematic intravenous thrombolytic alteplase (IV TPA) or surgical embolectomy, both of which are associated with significant morbidity and mortality. However, with the advent of endovascular techniques, recent studies have suggested that an endovascular approach to the treatment of acute smPE may be both safe and effective with excellent outcomes. The purpose of this study was to evaluate the outcomes of patients who have undergone catheter directed thrombolysis (CDT) for smPE at our institution in an effort to determine the safety of the procedure...

: : Endogenous dermal stem cells (DSCs) reside in the adult hair follicle mesenchyme and can be isolated and grown in vitro as self-renewing colonies called skin-derived precursors (SKPs). Following transplantation into skin, SKPs can generate new dermis and reconstitute the dermal papilla and connective tissue sheath, suggesting they could have important therapeutic value for the treatment of skin disease (alopecia) or injury. Controlled cell culture processes must be developed to efficiently and safely generate sufficient stem cell numbers for clinical use...

BACKGROUND: To optimize survival evaluation of Schwann cells (SCs) in vivo, we tested fluorescent labeling of the nucleus as an improved method of tracking and counting the transplanted SCs at sciatic nerve injury sites in rodents. We also investigated if co-administering cells with the glial growth factor Neuregulin-1 β (NRG1β) improves in vivo survival. New Method We transduced SCs using a Lentiviral vector with a nuclear localization signal (NLS) fused with mCherry and transplanted them in the sciatic nerve of rat post-crush injury (bilateral) either in the presence or absence of NRG1β in the injectate media...

Understanding the targeted cellular uptake of nanomaterials is an essential step to engineer and program functional and effective biomedical devices. In this respect, the targeting and ultrafast uptake of zeolite nanocrystals functionalized with Cetuximab antibodies (Ctxb) by cells overexpressing the epidermal growth factor receptor are described here. Biochemical assays show that the cellular uptake of the bioconjugate in the targeted cancer cells already begins 15 min after incubation, at a rate around tenfold faster than that observed in the negative control cells...

Glucocorticoids (GCs) regulate skin homeostasis and combat cutaneous inflammatory diseases; however, adverse effects of chronic GC treatments limit their therapeutic use. GCs bind and activate the GC receptor and the mineralocorticoid receptor (MR), transcription factors that recognize identical hormone responsive elements. Whether epidermal MR mediates beneficial or deleterious GC effects is of great interest for improving GC-based skin therapies. MR epidermal knockout mice exhibited increased keratinocyte proliferation and differentiation and showed resistance to GC-induced epidermal thinning...

The challenge of mimicking the extracellular matrix with artificial scaffolds that are able to reduce immunoresponse is still unmet. Recent findings have shown that mesenchymal stem cells (MSC) infiltrating into the implanted scaffold have effects on the implant integration by improving the healing process. Toward this aim, a novel polyamidoamine-based nanocomposite hydrogel is synthesized, cross-linked with porous nanomaterials (i.e., mesoporous silica nanoparticles), able to release chemokine proteins. A comprehensive viscoelasticity study confirms that the hydrogel provides optimal structural support for MSC infiltration and proliferation...

Sediment geochemistry of the Jakarta region, a densely populated tropical coast, is studied - with particular focus on rivers discharging to Jakarta Bay. Weathering volcanics in the river catchment area control the composition of major elements, As, Cr and in part Cu. In contrast, Zn, Ni, Pb and partly Cu are affected by anthropogenic sources, mainly in central Jakarta City. The data reflect a high variability of local emission sources, among which metal processing industries, fertilizers or untreated animal waste may be important...

Laminins are the most abundant non-collagenous basement membrane (BM) components, composed of an α, β and γ chain. The laminin γ1 chain, encoded by LAMC1, is the most abundant γ chain. The main laminin isoforms in the dermo-epidermal junction (DEJ) are laminin-332, laminin-511 and laminin-211, the latter being restricted to the lower part of hair follicles (HFs). Complete deletion of LAMC1 results in lethality around embryonic day 5.5. To study the function of laminin γ1 containing isoforms in skin development and maturation after birth, we generated mice lacking LAMC1 expression in basal keratinocytes (LAMC1(EKO)) using the keratin 14 (K14) Cre/loxP system...
