To date, guard cell promoters have been examined in only a few species, primarily annual dicots. A partial segment of the potato (Solanum tuberosum) KST1 promoter (KST1 partial promoter, KST1ppro) has previously been shown to confer guard cell expression in potato, tomato (Solanum lycopersicum), citrus [Troyer citrange (C. sinensis×Poncirus trifoliata)], and Arabidopsis (Arabidopsis thaliana). Here, we describe an extensive analysis of the expression pattern of KST1ppro in eight (previously reported, as well as new) species from five different angiosperm families, including the Solanaceae and the Cucurbitaceae, Arabidopsis, the monocot barley (Hordeum vulgare), and two perennial species: grapevine (Vitis vinifera) and citrus...

Médéric Diard, Wolf-Dietrich Hardt
Bacterial virulence is highly dynamic and context-dependent. For this reason, it is challenging to predict how molecular changes affect the growth of a pathogen in a host and its spread in host population. Two schools of thought have taken quite different directions to decipher the underlying principles of bacterial virulence. While molecular infection biology is focusing on the basic mechanisms of the pathogen-host interaction, evolution biology takes virulence as one of several parameters affecting pathogen spread in a host population...

In mice, the pathway involving PIWI and PIWI-interacting RNA (PIWI-piRNA) is essential to re-establish transposon silencing during male-germline reprogramming. The cytoplasmic PIWI protein MILI mediates piRNA-guided transposon RNA cleavage as well as piRNA amplification. MIWI2's binding to piRNA and its nuclear localization are proposed to be dependent upon MILI function. Here, we demonstrate the existence of a piRNA biogenesis pathway that sustains partial MIWI2 function and reprogramming activity in the absence of MILI...

Perception, cognition and behavior rely on flexible communication between microcircuits in distinct cortical regions. The mechanisms underlying rapid information rerouting between such microcircuits are still unknown. It has been proposed that changing patterns of coherence between local gamma rhythms support flexible information rerouting. The stochastic and transient nature of gamma oscillations in vivo, however, is hard to reconcile with such a function. Here we show that models of cortical circuits near the onset of oscillatory synchrony selectively route input signals despite the short duration of gamma bursts and the irregularity of neuronal firing...

OBJECTIVE: To present in detail our surgical technique and to show our initial experience with ureteral reimplantation using the transumbilical LESS approach to treat patients with ureteral stenosis secondary to various diseases and surgical complications. METHODS: We performed 7 ureteral reimplantations from February 2012, using the multichannel Richard- Wolf (KeyPort) platform placed transumbilical by a small 2-2,5 cm transversal incision. We always use a 3.5 mm minilaparoscopy accessory trocar in the right iliac fossa, that is crucial to perform the laparoscopic suturing safely for the patient and in an optimal time...

BACKGROUND: Dual disorders (co-occurring mental illness and substance abuse disorders in the same person) are extremely common among patients receiving mental health services. Integrated treatment has been proposed as the standard of care and it describes a flexible combination of treatments from the mental health and addiction fields that are blended together in the therapy. Scientific evidence for survival of dual disorders patients (DDPs), who had integrated dual disorders inpatient care, is lacking...

Atopic dermatitis (AD) and psoriasis are driven by alternate type 2 and type 17 immune responses, but some proteins might be critical to both diseases. Here we show that a deficiency of the TNF superfamily molecule TWEAK (TNFSF12) in mice results in defective maintenance of AD-specific T helper type 2 (Th2) and psoriasis-specific Th17 cells in the skin, and impaired expression of disease-characteristic chemokines and cytokines, such as CCL17 and TSLP in AD, and CCL20 and IL-19 in psoriasis. The TWEAK receptor, Fn14, is upregulated in keratinocytes and dermal fibroblasts, and TWEAK induces these cytokines and chemokines alone and in synergy with the signature T helper cytokines of either disease, IL-13 and IL-17...

The nonlinear conjugate gradient (CG) algorithm is a very effective method for optimization, especially for large-scale problems, because of its low memory requirement and simplicity. Zhang et al. (IMA J. Numer. Anal. 26:629-649, 2006) firstly propose a three-term CG algorithm based on the well known Polak-Ribière-Polyak (PRP) formula for unconstrained optimization, where their method has the sufficient descent property without any line search technique. They proved the global convergence of the Armijo line search but this fails for the Wolfe line search technique...

Zekayi Kutlubay, Yalçın Tüzün, Ronni Wolf
The pathergy test produces a nonspecific hyperreactive lesion in Behçet's disease (BD), a finding that has been known since 1937. Pathergy refers to the development of new skin lesions or the aggravation of existing ones after trivial trauma. In clinical practice, the pathergy test induces a skin response by needleprick, with positive reactions manifesting as a papule or pustule developing by 48 hours. The pathergy test is one of the major features and diagnostic criteria of the disease. It is very similar to the erythematous papules or pustules that appear spontaneously in patients with BD...

Homogenization applied to cheese milk has shown to increase lipolysis but its use is not spread as it can induce detrimental effects. The aim of this work was to assess the effect of low-pressure homogenization of the cream followed by pre-incubation of cheese milk on the composition, ripening index, lipolysis and volatile profiles of hard cooked cheeses. For that, control and experimental miniature Reggianito cheeses were made and analyzed during ripening (3, 45 and 90days). Homogenization had no impact on composition and proteolysis...

Ex vivo lung perfusion (EVLP) has been developed as a method to reassess and recondition marginal lungs. However, evaluation during procedures is limited to a combination of physiologic variables such as gas exchange, pulmonary mechanics, and pulmonary vascular resistance. The aim of this study was to analyze the feasibility of real-time computed tomographic (CT) imaging to improve the evaluation of the lung during EVLP procedures.

In patients with relapsed or refractory (r/r) AML, allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is considered to be the only treatment providing long-term disease control. The BRIDGE trial studied the safety and efficacy of a clofarabine-based salvage therapy prior to HSCT in patients with r/r AML. Here, we report the long-term follow up of this Phase II, multi-center trial and exploratory analyses on the impact of comorbidity on outcome. Eighty-four patients with a median age of 61 years (range 40 - 75) were enrolled...

Lake Erie is one of the most valuable natural resources in the United States, providing billions of dollars in benefits each year to recreationalists, homeowners and local governments. The ecosystem services provided by Lake Erie, however, are under threat due to harmful algal blooms. This paper provides recreational damage estimates using spatially and temporally varying algae measures and monthly fishing permit sales collected between 2011 and 2014. Results indicate that fishing license sales drop between 10% and 13% when algal conditions surpass the World Health's Organization's moderate health risk advisory threshold of 20,000 cyanobacteria cells/mL...

Mitofusin-2 (MFN2) is a GTPase in the outer mitochondrial membrane involved in the regulation of mitochondrial fusion and bioenergetics. MFN2 also plays a role in mitochondrial fusion induced by changes in the intracellular redox state. Adding oxidized glutathione (GSSG), the core cellular stress indicator, to mitochondrial preparations stimulates mitochondrial fusion by inducing disulphide bond-mediated oligomer formation of MFN2 and its homolog MFN1 which involve cysteine 684 (C684) of MFN2. Mitochondrial hyperfusion represents an adaptive stress response that confers transient protection by increasing mitochondrial ATP production but how this depends on the thiol switch C684 in MFN2 has not been investigated...

It has been shown that patients with electric acoustic stimulation (EAS) perform better in noisy environments than patients with a cochlear implant (CI). One reason for this could be the preserved access to acoustic low-frequency cues including the fundamental frequency (F0). Therefore, our primary aim was to investigate whether users of EAS experience a release from masking with increasing F0 difference between target talker and masking talker. The study comprised 29 patients and consisted of three groups of subjects: EAS users, CI users and normal-hearing listeners (NH)...
