Automated Ramen Noodle Vending Machine

Indiana University Purdue University IndianapolisContained in the following report is a complete and detailed document of the design and implementation for the development of an automated ramen noodle vending machine unit. Covered topics include justification and specification development, which considers target consumer audience as well as some considerations for safety ratings and features that are required for consumer appliances. Also covered is the development and implementation phase, entailing translating design into a physical and functional prototype that achieves specifications detailed in the design phase. There are three major components of the development phase: hardware, interface and software. Each component of development is covered in detail, including troubleshooting and on-the-fly changes made to design to accommodate issues that arise during the prototype development. The last section of the document includes some considerations for iterative design. Issues encountered during prototype development will also be documented. A fully detailed operations guide will also be included. In the appendices of the document are the full printout of the software, detailed spec sheets of individual hardware components, as well as documents from the design phase.Electrical Engineering Technolog

Intraparenchymal Striatal Transplants Required for Maintenance of Behavioral Recovery in an Animal Model of Huntington's Disease

Rats which receive injections of kainic acid (KA) into the striatum show many of the anatomical, biochemical and behavioral abnormalities seen in patients with Huntington's disease. Recently, it has been reported that fetal striatal transplants into the lesioned striatum could normalize the neurological and behavioral abnormalities produced by the KA lesion. The present study examined the issue of transplant integration in producing behavioral recovery. In one experiment, lesioned animals with transplants located within the lateral ventricle were compared against parenchymally transplanted rats. It was found that unless the ventricular transplant grew into the lesioned striatum there was no recovery. The second experiment demonstrated that electrolytic destruction of a successful fetal striatal transplant could reverse the transplant-induced behavioral recovery. These results suggest that the integrity of the transplant is important in maintaining behavioral recovery. A continuing functional interaction between the host brain and transplanted tissue may be a vital element in the success of the fetal striatal transplant

Close similarities between Cherry chlorotic rusty spot disease from Italy and Cherry leaf scorch from Spain

Cherry chlorotic rusty spot (CCRS), a disease affecting sweet and sour cherry in Southern Italy was regularly found associated with an unidentified fungus and with a complex pattern of viral-like double-stranded RNAs as well as with two small circular RNAs (cherry small circular RNAs, cscRNAs). Further studies revealed that i) the ds-RNAs correspond to the genome of different mycoviruses belonging to the genera Chrysovirus, Partitivirus and Totivirus and ii) the two viroid-like RNAs consist of two groups of variants with similar sequences but differing in size (394–415 and 372–377 nt for cscRNA1 and cscRNA2, respectively). Here we report that the dsRNAs of Chrysovirus and Partitivirus have been detected by RT-PCR analysis with CCRS specific primers in nucleic acid preparations from cherry leaves affected by cherry leaf scorch (CLS) in Spain, a disease whose etiological agent is the ascomycetes Apiognomonia erythrostoma, order Diaporthales. Moreover, Northern-blot hybridization assays showed that a viroid-like RNA comigrating and sharing high sequence similarity with the cscRNA1 previously reported in Italy, accumulate in leaves from CLS affected trees in Spain. These data, together with other evidence showing similar symptoms, disease cycle and fungal fructifications in CCRS and CLS affected trees, suggest a close relationship between the two cherry disorders.Keywords: dsRNAs, cscRNAs, Apiognomonia erythrostoma, Diaporthale

Neuroinflammatory processes, A1 astrocyte activation and protein aggregation in the retina of Alzheimer’s disease patients, possible biomarkers for early diagnosis

Alzheimer's disease (AD), a primary cause of dementia in the aging population, is characterized by extracellular amyloid-beta peptides aggregation, intracellular deposits of hyperphosphorylated tau, neurodegeneration and glial activation in the brain. It is commonly thought that the lack of early diagnostic criteria is among the main causes of pharmacological therapy and clinical trials failure; therefore, the actual challenge is to define new biomarkers and non-invasive technologies to measure neuropathological changes in vivo at pre-symptomatic stages. Recent evidences obtained from human samples and mouse models indicate the possibility to detect protein aggregates and other pathological features in the retina, paving the road for non-invasive rapid detection of AD biomarkers. Here, we report the presence of amyloid beta plaques, tau tangles, neurodegeneration and detrimental astrocyte and microglia activation according to a disease associated microglia phenotype (DAM). Thus, we propose the human retina as a useful site for the detection of cellular and molecular changes associated with Alzheimer's disease
