Two up-flow anaerobic sludge blanket (UASB) reactors (RM with 10 g Fe L-1 magnetite, RB without magnetite) feeding with synthetic wastewater were built to investigate the effect of magnetite addition on anaerobic digestion (AD) performance during start-up and starvation recovery stages. With the magnetite addition, the COD removal efficiency and biogas production during the two stages were enhanced, and the recovery time of RM was shortened by about 50%. The reduced synthesis of riboflavin and heme c along with enhanced sludge conductivity of RM indicated that magnetite could replace their roles for efficient extracellular electron transfer (EET), which favors the growth of anaerobes...

It is not understood how the human T cell leukemia virus human T-lymphotropic virus-1 (HTLV-1), a retrovirus, regulates the in vivo balance between transcriptional latency and reactivation. The HTLV-1 proviral plus-strand is typically transcriptionally silent in freshly isolated peripheral blood mononuclear cells from infected individuals, but after short-term ex vivo culture, there is a strong, spontaneous burst of proviral plus-strand transcription. Here, we demonstrate that proviral reactivation in freshly isolated, naturally infected primary CD4+ T cells has 3 key attributes characteristic of an immediate-early gene...

Herpes simplex virus-2 (HSV-2) is a common sexually transmitted infection with a highly variable clinical course. Many infections quickly become subclinical, with episodes of spontaneous virus reactivation. To study the host/HSV-2 interactions an animal model of subclinical HSV-2 infection is needed. In an effort to develop a relevant model, rhesus macaques (RM) were inoculated intravaginally with two or three HSV-2 strains (186, 333 and/or G); total dose 1x107 pfu HSV-2 per animal. Infectious HSV-2 and HSV-2 DNA was consistently shed in vaginal swabs for the first 7-14 days after each inoculation...

BACKGROUND: Whole blood impedance platelet aggregometry (Multiplate-) can be performed with different agonists to evaluate platelet function. Although the manufacturer recommends disposal of stored reagents after 1 month at -20°C or 24 hours at 4°C, reagent integrity after reconstitution under different storage conditions is unknown. If reagent integrity is stable for longer periods, assay costs could decrease dramatically. OBJECTIVES: This study aimed to determine the stability of reconstituted arachidonic acid (AA) and adenosine diphosphate (ADP) platelet agonists stored at -20°C and -80°C for up to 6 months...

Remote microphones (RMs) have been developed to support hearing aid (HA) users in understanding distant talkers. In traditional clinical applications, a drawback of these systems is the deteriorated speech intelligibility in the near field. This study investigates advantages and disadvantages of clinical RM usage and the effects of different directionality settings of the HAs in complex listening situations in the laboratory. Speech intelligibility was investigated in 15 experienced severely hearing impaired participants in a noisy environment using a dual-task test paradigm where the tasks were presented from either a near field or a far field loudspeaker...

The purpose of this study is to examine and further understand the effects of post activation potentiation on Achilles tendon (AT) thickness, elasticity and stiffness among basketball players. Basketball is one of the world's most popular and widely viewed sports. One of the main factors which athletes depend on during their performance is elastic energy coming straight from the AT. Contractile activity increases the muscular force and is known in science as post activation potentiation (PAP). Twelve basketball players (aged 21...

CD4+ T cells are major players in the immune response against several diseases; including AIDS, leishmaniasis, tuberculosis, influenza and cancer. Their activation has been successfully achieved by administering antigen coupled with antibodies, against DC-specific receptors in combination with adjuvants. Unfortunately, most of the adjuvants used so far in experimental models are unsuitable for human use. Therefore, human DC-targeted vaccination awaits the description of potent, yet nontoxic adjuvants. The nontoxic cholera B subunit (CTB) can be safely used in humans and it has the potential to activate CD4+ T cell responses...

BACKGROUND: Iatrogenic or traumatic injury to the spinal accessory nerve is a rare but debilitating injury. An effective treatment, known as the Eden-Lange modification triple-tendon transfer procedure, involves the transfer of the rhomboid major (RM), rhomboid minor (Rm), and levator scapulae (LS). Careful detachment of their insertions is necessary to avoid injury of the dorsal scapular nerve (DSN). This study evaluated the surgical anatomy and safety of the DSN relative to this procedure...
