Physico-chemical characteristics,water absorption,soaking and cooking properties of some Sicilian populations of chickpea (Cicer arietinum L.)

The physical and physico-chemical properties of several Kabuli chickpeas originating from Sicily (South Italy) were determined. Twelve genotypes in all, including two controls (ILC484, of the ICARDA genebank, and ‘Calia’, a traditional Italian cultivar), were analysed. A large variability among genotypes was ascertained for swelling capacity (coefficient of variation [CV]=27.9%), swelling index (CV=30.5%) and calcium content (CV=39.3%). The lowest variability was observed for seed coat (CV=8.6%) and seed weight (CV=9.6%). Genotype statistically affected all traits, whose mean values were: seed weight, 0.340±0.03 g; seed coat, 4.47±0.38%; seed volume, 0.292±0.04 ml; seed density, 1.18±0.15 g/ml; hydration capacity, 0.361±0.09 g/seed; hydration index, 1.05±0.21; swelling capacity, 0.346±0.10 ml/seed; swelling index, 1.21±0.37; cooking texture, 2.61±0.38 kg/cm²; and calcium, 109.6±43.11 mg/100 g dry weight. Correlation coefficients among characteristics were also estimated. The genotype ‘44M33’ was found to be interesting having good seed weight and low seed coat incidence and calcium content, all important attributes affecting cooking quality.

Lab-on-a-chip: Emerging analytical platforms for immune-mediated diseases

Miniaturization of analytical procedures has a significant impact on diagnostic testing since it provides several advantages such as: reduced sample and reagent consumption, shorter analysis time and less sample handling. Lab-on-a-chip (LoC), usually silicon, glass, or silicon-glass, or polymer disposable cartridges, which are produced using techniques inherited from the microelectronics industry, could perform and integrate the operations needed to carry out biochemical analysis through the mechanical realization of a dedicated instrument.Analytical devices based on miniaturized platforms like LoC may provide an important contribution to the diagnosis of high prevalence and rare diseases. In this paper we review some of the uses of Lab-on-a-chip in the clinical diagnostics of immune-mediated diseases and we provide an overview of how specific applications of these technologies could improve and simplify several complex diagnostic procedures.     

Preliminary Evaluation of the Safety and Efficacy of Standard Intravenous Immunoglobulins in Pregnant Women with Primary Cytomegalovirus Infection

Hyperimmune globulins were reported to prevent and treat fetal cytomegalovirus (CMV) infection during pregnancy. Here, we report that infusions of standard human intravenous immunoglobulin significantly increase CMV IgG titers and avidity indexes in pregnant women, paving the way to their use for passive transfer of maternal CMV humoral immunity to fetuses. Preliminary data on perinatal outcomes of the first 67 newborns are encouraging.     

Mrs. Doubtfire Mentoring Program: Helping Children in Residential Care Transition to Bedtime

An exploratory qualitative study was conducted for the Mrs. Doubtfire mentoring program designed to connect volunteers with young children (6–11 years) in residential care to help with the bedtime transition and develop positive relationships with caring adults. Details of the program are provided. Positive effects on the agency, staff, volunteers, and children are discussed. Mrs. Doubtfire provides an innovative approach to meeting needs of children in residential care while also building strong community relationships and dedicated volunteers.     

The use of personalized biomarkers and liquid biopsies to monitor treatment response and disease recurrence in locally advanced rectal cancer after neoadjuvant chemoradiation

Neoadjuvant chemoradiotherapy (nCRT) followed by surgery is the mainstay treatment for locally advanced rectal cancer. Variable degrees of tumor regression are observed after nCRT and alternative treatment strategies, including close surveillance without immediate surgery, have been investigated to spare patients with complete tumor regression from potentially adverse outcomes of radical surgery. However, clinical and radiological assessment of response does not allow accurate identification of patients with complete response. In addition, surveillance for recurrence is similarly important for these patients, as early detection of recurrence allows salvage resections and adjuvant interventions. We report the use of liquid biopsies and personalized biomarkers for monitoring treatment response to nCRT and detecting residual disease and recurrence in patients with rectal cancer. We sequenced the whole-genome of four rectal tumors to identify patient-specific chromosomal rearrangements that were used to monitor circulating tumor DNA (ctDNA) in liquid biopsies collected at diagnosis and during nCRT and follow-up. We compared ctDNA levels to clinical, radiological and pathological response to nCRT. Our results indicate that personalized biomarkers and liquid biopsies may not be sensitive for the detection of microscopic residual disease. However, it can be efficiently used to monitor treatment response to nCRT and detect disease recurrence, preceding increases in CEA levels and radiological diagnosis. Similar good results were observed when assessing tumor response to systemic therapy and disease progression. Our study supports the use of personalized biomarkers and liquid biopsies to tailor the management of rectal cancer patients, however, replication in a larger cohort is necessary to introduce this strategy into clinical practice.
