The Pti1 kinase was identified from a reverse genetic screen as contributing to pattern-triggered immunity (PTI) against Pseudomonas syringae pv. tomato (Pst). This was unexpected because Pti1 was originally identified as an interactor of the Pto kinase and was implicated in effector-triggered immunity. The tomato genome has two Pti1 genes, referred to as Pti1a and Pti1b. A hairpin-Pti1 (hpPti1) construct was developed and used to generate two independent stable transgenic tomato lines, which had reduced transcript abundance of both genes...

PURPOSE: In Le Fort 1 osteotomy when a maxillary impaction is necessary, surgeons have to face different anatomical problems. (1) To determine the best bone resection route, they have to consider the situation of dental roots, infraorbital foramen and maxillary artery. (2) In case of Le Fort 1 osteotomy combined with a mandibular sagittal split osteotomy, the palate has to be replaced in horizontal position although there is no anatomical landmark. (3) In case of Gummy smiles, it can be due to either long face or short upper lip...

Pathogen- or microbe-associated molecular patterns (PAMPs/MAMPs) are detected as nonself by host pattern recognition receptors (PRRs) and activate pattern-triggered immunity (PTI). Microbial invasions often trigger the production of host-derived endogenous signals referred to as dangeror damage-associated molecular patterns (DAMPs), which are also perceived by PRRs to modulate PTI responses. Collectively, PTI contributes to host defense against infections by a broad range of pathogens. Remarkable progress has been made toward demonstrating the cellular and physiological responses upon pattern recognition, elucidating the molecular, biochemical, and genetic mechanisms of PRR activation as well as dissecting the complex signaling networks that orchestrate PTI responses...

Stefanie Ranf
In plants, sensing of Pathogen/Microbe-Associated Molecular Patterns (PAMPs/MAMPs) and host-derived Damage-Associated Molecular Patterns (DAMPs) by host cell surface Pattern Recognition Receptors (PRRs) activates Pattern-Triggered Immunity (PTI). The identification of an increasing number of immunogenic patterns and PRRs illustrates that PTI is a universal defence mechanism against pathogens, pests, and parasitic plants, and that evolutionary selective pressure drives diversification of molecular patterns and diversity of PRRs...

BACKGROUND: Persistent T-wave inversion (PTI) after ST-elevation myocardial infarction (STEMI) is associated with worse clinical outcome; however, the underlying mechanism between PTI and poor prognosis is incompletely understood. We sought to investigate the relationship between PTI and myocardial damage assessed by cardiac magnetic resonance (CMR) following STEMI. METHODS: In this prospective observational study, we included 142 consecutive revascularized STEMI patients...

The data in this article are the simulation results of 1248 cases that were carried out to detect anti-insulation behaviour in the article titled "Anti-insulation mitigation by altering the envelope layers' configuration" (Idris and Mae, 2017) [1]. These cases are generated by a matrix of 13 climates, 6 envelope layer configurations, 4 occupancy profiles and 4 levels of insulation thickness. The data are concerned with the annual cooling and heating loads of these cases. In addition, the data include the Point of Thermal Inflexion (PTI) values and their anti-insulation pattern, when PTI is found...

Receptor-like kinases BAK1 and BKK1 modulate multiple cellular processes including brassinosteroid signaling and PRR-mediated PTI in Arabidopsis. Our previous reports also demonstrated that bak1 bkk1 double mutants exhibit a spontaneous cell death phenotype under normal growth condition. With an unknown mechanism, the cell death in bak1 bkk1 is significantly suppressed when grown in dark but can be quickly induced by light. Furthermore, little is known about intrinsic components involved in BAK1 and BKK1-regulated cell death pathway...

INTRODUCTION: Our novel technique of pen torch transillumination (PTI) uses a cheap and easily available instrument (Penlite-LP212(®), Energizer(®), Missouri, USA) to visualize superficial veins invisible to the naked eye. We evaluate the efficacy of PTI in improving venepuncture success rate (SR) for patients with poor venous access. METHODS: This prospective randomized controlled trial looked at adult patients (n = 69) aged 21-90 with difficult venous access (history of ≥3 consecutive attempts required for successful cannulation during the current admission) requiring non-emergent venepuncture...

BACKGROUND: PTI and ETI are the two major defence mechanisms in plants. ETI is triggered by the detection of pathogen effectors, or their activity, in the plant cell and most of the time involves internal receptors known as resistance (R) genes. An increasing number of R genes responsible for recognition of specific effectors have been characterised over the years; however, methods to identify R genes are often challenging and cannot always be translated to crop plants. RESULTS: We present a novel method to identify R genes responsible for the recognition of specific effectors that trigger a hypersensitive response (HR) in Nicotiana benthamiana...

We show that amyloid-β1-42 (Aβ42) triggers a conformational change in the scaffolding protein filamin A (FLNA) to induce FLNA associations with α7-nicotinic acetylcholine receptor (α7nAChR) and toll-like receptor 4 (TLR4). These aberrant associations respectively enable Aβ42's toxic signaling via α7nAChR to hyperphosphorylate tau protein, and TLR4 activation to release inflammatory cytokines. PTI-125 is a small molecule that preferentially binds altered FLNA and restores its native conformation, restoring receptor and synaptic activities and reducing its α7nAChR/TLR4 associations and downstream pathologies...

Historically in the biopharmaceutical setting, USP<905> has been used to establish that a batch of drug product has acceptable content uniformity. More recently, alternative approaches such as the two one-sided parametric tolerance interval test (PTI-TOST) have been proposed to establish content uniformity. Traditionally, the PTI-TOST is implemented as a sequential, two-tiered test, under the generally accepted assumption that the data are independently and identically distributed. Since the material is sequenced through the manufacturing process over a period of time, there are conceptually arguable locations within each batch, for instance: beginning, middle, and end...

Plant-parasitic nematodes are destructive pests causing losses of billions of dollars annually. An effective plant defence against pathogens relies on the recognition of pathogen-associated molecular patterns (PAMPs) by surface-localised receptors leading to the activation of PAMP-triggered immunity (PTI). Extensive studies have been conducted to characterise the role of PTI in various models of plant-pathogen interactions. However, far less is known about the role of PTI in roots in general and in plant-nematode interactions in particular...

BACKGROUND: The hospital environment leaves preterm infants (PTIs) exposed to various stressors that can disrupt their growth and development. Developmental interventions such as music may be an important strategy to mitigate PTI's stress. This brief evaluates current evidence regarding the impact of music therapy on outcomes for PTIs. PURPOSE: The question guiding this brief is "Do various types of music therapy positively affect physiologic indicators, feeding behaviors/length of stay (LOS) and pain management outcomes for PTIs?" SEARCH STRATEGY: CINAHL/MEDLINE Complete and PubMed databases were searched using keywords preterm infants, premature infants, preterm baby, premature baby, NICU baby, music, and music therapy...

Pathogen-associated molecular patterns (PAMPs) are detected by plant pattern recognition receptors (PRRs), which gives rise to PAMP-triggered immunity (PTI). We characterized a novel fungal PAMP, Cell Death Inducing 1 (RcCDI1), identified in the Rhynchosporium commune transcriptome sampled at an early stage of barley (Hordeum vulgare) infection. The ability of RcCDI1 and its homologues from different fungal species to induce cell death in Nicotiana benthamiana was tested following agroinfiltration or infiltration of recombinant proteins produced by Pichia pastoris...

Pseudomonas syringae infects diverse plant species and is widely used as a model system in the study of effector function and the molecular basis of plant diseases. Although the relationship between bacterial metabolism, nutrient acquisition, and virulence has attracted increasing attention in bacterial pathology, it is largely unexplored in P. syringae. The Crc (catabolite repression control) protein is a putative RNA-binding protein that regulates carbon metabolism as well as a number of other factors in the pseudomonads...

Avoiding obstacles is essential for successful navigation through complex environments. This study aimed to clarify what strategies are used by a typical quadruped, the cat, to avoid obstacles during walking. Four cats walked along a corridor 2.5 m long and 25 or 15 cm wide. Obstacles, small round objects 2.5 cm in diameter and 1 cm in height, were placed on the floor in various locations. Movements of the paw were recorded with a motion capture and analysis system (Visualeyez, PTI). During walking in the wide corridor, cats' preferred strategy for avoiding a single obstacle was circumvention, during which the stride direction changed, while stride duration and swing-to-stride duration ratio were preserved...

BACKGROUND: Tonic immobility is an involuntary motor and vocal inhibition reaction, considered the last-ditch response of the defensive cascade model. It is elicited in context of inescapable threat and perception of entrapment. Our aim was to investigate the association between different traumatic events and peritraumatic tonic immobility (PTI) in a representative sample of the general population. METHODS: This is a cross-sectional study of general population from Rio de Janeiro and São Paulo with 3231 victims of traumatic events aged 15-75 years who completed the Tonic Immobility Scale (TIS)...

Granulosa cell (GC) culture models mimicking the intrafollicular environment are limited. Such models have a great potential in reproductive toxicity studies. The buffalo, a monovulatory species like humans, could be a better model than polyovulatory rodents. Therefore, we targeted the development and characterization of three-dimensional (3D) culture systems for buffalo GCs. The GCs from small ovarian follicles (SF) maintained the CYP19 gene expression for 144 hr in a 2D culture system. Hence, GCs from SF were cultured directly in 3D using hanging drop and Poly-([2-hydroxyethyl methacrylate]) (polyHEMA) methods in the DMEM media containing 1 ng/ml FSH and 10 ng/ml IGF-1 for 144 hr...

Induced resistance response is a potent and cost effective plant defense against pathogen attack. The effectiveness and underlying mechanisms of the suppressive ability by Bacillus cereus AR156 to Pseudomonas syringae pv. tomato DC3000 (Pst DC3000) in Arabidopsis has been investigated previously; however, the strength of induced systemic resistance (ISR) activity against Botrytis cinerea remains unknown. Here, we show that root-drench application of AR156 significantly reduces disease incidence through activation of ISR...
