The elicitor AsES (Acremonium strictum Elicitor Subtilisin) is a 34 KDa subtilisin-like protein secreted by the opportunistic fungus Acremonium strictum. AsES activates the innate immunity and confers resistance against anthracnose and grey mold diseases in strawberry plants (Fragaria x ananassa Duch.) and the last disease also in Arabidopsis. In the present work, we show that upon AsES recognition, a cascade of defense responses is activated, including: calcium influx, biphasic oxidative burst (O2(.-) and H2O2), HR response, accumulation of autofluorescent compounds, cell wall reinforcement with callose and lignin deposition, salicylic acid accumulation, and expression of defense-related genes such as FaPR1, FaPG1, FaMYB30, FaRBOH-D, FaRBOH-F, FaCHI23 and FaFLS...

BACKGROUND: Cartilage lesions of the knee are difficult to treat. Lesion size is a critical factor in treatment algorithms, and the accurate, reproducible sizing of lesions is important. In this study, we evaluated the interrater and intrarater reliability of, and correlations in relation to, various arthroscopic sizing techniques. METHODS: Five lesions were created in each of 10 cadaveric knees (International Cartilage Repair Society grade 3C). Three orthopaedic surgeons used 4 techniques (visualization and use of a 3-mm probe, a simple metal ruler, and a sliding metallic ruler tool) to estimate lesion size...

The biopharmaceutical industry produces non-sterile and/or low-bioburden intermediates and bulk biologics (i.e. Drug Substances) using bioburden controlled processes in accordance to Q7A and Annex 2. In many cases, single mold isolation events have received a high level of scrutiny; the goal of this paper is to challenge this paradigm and provide the rationale for an enhanced control approach that focuses on trending of mold species as microbial indicators rather than on single isolation events. Molds, can also be part (in much lower numbers) of the normal microbial population of a biologics manufacturing facility and, therefore, mold isolation is not an unexpected event in non-aseptic processing environments...

Although wafer-level camera lenses are a very promising technology, problems such as warpage with time and non-uniform thickness of products still exist. In this study, finite element simulation was performed to simulate the compression molding process for acquiring the pressure distribution on the product on completion of the process and predicting the deformation with respect to the pressure distribution. Results show that the single-gate compression molding process significantly increases the pressure at the center of the product, whereas the multi-gate compressing molding process can effectively distribute the pressure...

Patients with cleft lip and/or palate go through a lifelong journey of multidisciplinary care, starting from before birth and extending until adulthood. Presurgical orthopedic (PSO) treatment is one of the earliest stages of this care plan. In this paper we provide a review of the PSO treatment. This review should help general and specialist dentists to better understand the cleft patient care path and to be able to answer patient queries more efficiently. The objectives of this paper were to review the basic principles of PSO treatment, the various types of techniques used in this therapy, and the protocol followed, and to critically evaluate the advantages and disadvantages of some of these techniques...

REVIEW
Ahmad Alshannaq, Jae-Hyuk Yu
Mycotoxins are toxic secondary metabolites produced by certain filamentous fungi (molds). These low molecular weight compounds (usually less than 1000 Daltons) are naturally occurring and practically unavoidable. They can enter our food chain either directly from plant-based food components contaminated with mycotoxins or by indirect contamination from the growth of toxigenic fungi on food. Mycotoxins can accumulate in maturing corn, cereals, soybeans, sorghum, peanuts, and other food and feed crops in the field and in grain during transportation...

Grain polysaccharides represent potential valuable raw materials for next-generation advanced and environmentally friendly plastics. Thermoplastic starch (TPS) is processed using conventional plastic technology, such as casting, extrusion, and molding. However, to adapt the starch to specific functionalities chemical modifications or blending with synthetic polymers, such as polycaprolactone are required (e.g. Mater-Bi). As an alternative, all-natural and compostable bio-plastics can be produced by blending starch with other polysaccharides...
