CD8(+) T cell recognition of virus-infected cells is characteristically restricted by major histocompatibility complex (MHC) class I, although rare examples of MHC class II restriction have been reported in Cd4-deficient mice and a macaque SIV vaccine trial using a recombinant cytomegalovirus vector. Here, we demonstrate the presence of human leukocyte antigen (HLA) class II-restricted CD8(+) T cell responses with antiviral properties in a small subset of HIV-infected individuals. In these individuals, T cell receptor β (TCRβ) analysis revealed that class II-restricted CD8(+) T cells underwent clonal expansion and mediated killing of HIV-infected cells...

BACKGROUND: Regular physical activity is important for improving and maintaining health, but sedentary behavior is difficult to change. Providing objective, real-time feedback on physical activity with wearable motion-sensing technologies (activity monitors) may be a promising, scalable strategy to increase physical activity or decrease weight. PURPOSE: We synthesized the literature on the use of wearable activity monitors for improving physical activity and weight-related outcomes and evaluated moderating factors that may have an impact on effectiveness...

The Marseille, France, metropolitan area is home to a heavily concentrated industrial region directly adjacent to residential communities. These towns have been subjected to a wide variety of social science and public health studies, but residents continue to have many questions about health concerns for which they currently have primarily anecdotal evidence. Reflecting on our in-progress research in two of these towns, we argue that community-based participatory research that draws from both social science and public health science can be successfully adapted to the French political and cultural context and is key for developing environmental health research that is relevant for community residents and local leaders...

Integration of complex photonic structures onto optical fiber facets enables powerful platforms with unprecedented optical functionalities. Conventional nanofabrication technologies, however, do not permit viable integration of complex photonic devices onto optical fibers owing to their low throughput and high cost. In this paper we report the fabrication of a three-dimensional structure achieved by direct nanoimprint lithography on the facet of an optical fiber. Nanoimprint processes and tools were specifically developed to enable a high lithographic accuracy and coaxial alignment of the optical device with respect to the fiber core...

In this Letter, we present a Fresnel lens fabricated on the end of an optical fiber. The lens is fabricated using nanoimprint lithography of a functional high refractive index material, which is suitable for mass production. The main advantage of the presented Fresnel lens compared to a conventional fiber lens is its high refractive index (n=1.68), which enables efficient light focusing even inside other media, such as water or an adhesive. Measurement of the lens performance in an immersion liquid (n=1.51) shows a near diffraction limited focal spot of 810 nm in diameter at the 1/e<sup>2</sup> intensity level for a wavelength of 660 nm...

Recent research in identification of brain injury after trauma shows many possible blood biomarkers that may help identify the fetus and neonate with encephalopathy. Traumatic brain injury shares many common features with perinatal hypoxic-ischemic encephalopathy. Trauma has a hypoxic component, and one of the 1st physiologic consequences of moderate-severe traumatic brain injury is apnea. Trauma and hypoxia-ischemia initiate an excitotoxic cascade and free radical injury followed by the inflammatory cascade, producing injury in neurons, glial cells and white matter...

INTRODUCTION: Chronic pain in children and adolescents has a major impact on their life in terms of school, sleep as well as family and social life. Teenagers aged 13-15 and girls are at the highest risk. Zeltzer et al. established a bio-psychosocial model of chronic pain in 1998 to account for all its dimensions and advocated a multidisciplinary management plan. Programs based on their principles target specific symptoms such as anxiety and loss of function, while treating underlying factors and teaching coping skills to patients and their families...

Chronic pelvic pain is one of the main causes for repeated ambulatory and hospital visits. The main findings on exploratory laparoscopy performed for these complaints are endometriosis and adhesions, while in more than 50% of cases, no cause for the pain is found. In 1955, Allen and Masters reported pain associated with traumatic labor. They reported retroverted and hyper-mobile uterus in all women and during operation, tears in the posterior serosa of the broad igament. A few therapeutic options have been discussed, including repair of the tears, but without long term follow-up and significant relief of symptoms...

Since the 1950s, vision researchers have been working towards the ambitious goal of restoring a functional level of vision to the blind via electrical stimulation of the visual pathways. Groups based in Australia, USA, Germany, France and Japan report progress in the translation of retinal visual prosthetics from the experimental to clinical domains, with two retinal visual prostheses having recently received regulatory approval for clinical use. Regulatory approval for cortical visual prostheses is yet to be obtained; however, several groups report plans to conduct clinical trials in the near future, building upon the seminal clinical studies of Brindley and Dobelle...

BACKGROUND: In malignant glioma (MG) patients undergoing radiation therapy (RT) with concomitant temozolomide, chemoradiation-induced nausea and vomiting (cRINV) degrades quality of life (QoL) and reduces treatment adherence, which thereby potentially compromises cancer control. METHODS: We conducted a 6-week phase II single-arm trial of PAL, a second-generation 5-HT3RA antiemetic, for cRINV prevention in MG patients receiving radiation therapy (RT; 54-60 Gy) and concomitant daily temozolomide (TMZ; 75 mg/m(2)/dX42d)...

Borrelia burgdorferi sensu stricto isolates from patients with erythema migrans in Europe and the United States were compared by genotype, clinical features of infection, and inflammatory potential. Analysis of outer surface protein C and multilocus sequence typing showed that strains from these 2 regions represent distinct genotypes. Clinical features of infection with B. burgdorferi in Slovenia were similar to infection with B. afzelii or B. garinii, the other 2 Borrelia spp. that cause disease in Europe, whereas B...

Proton transport plays an important role in many biological processes due to the ability of protons to rapidly translocate along chains of hydrogen-bonded water molecules. Molecular dynamics simulations have predicted that confinement in hydrophobic nanochannels should enhance the rate of proton transport. Here, we show that 0.8-nm-diameter carbon nanotube porins, which promote the formation of one-dimensional water wires, can support proton transport rates exceeding those of bulk water by an order of magnitude...

Epigenetic modifications, including DNA methylation, represent a potential mechanism for environmental impacts on human disease. Maternal smoking in pregnancy remains an important public health problem that impacts child health in a myriad of ways and has potential lifelong consequences. The mechanisms are largely unknown, but epigenetics most likely plays a role. We formed the Pregnancy And Childhood Epigenetics (PACE) consortium and meta-analyzed, across 13 cohorts (n = 6,685), the association between maternal smoking in pregnancy and newborn blood DNA methylation at over 450,000 CpG sites (CpGs) by using the Illumina 450K BeadChip...
