Analysis of water application techniques for growing tomatoes in small pots on different substrates. Note 2

The response of the tomato plants to the irrigation regimes compared in the previous study, particularly when compared with the response to the peat fraction in the mixture, was modest, often irregular and subject to complex interactions with the former factor. This result could depend partially on the fact that the parameters for the water regime applied during the trials were chosen to prevent exposing the plants to excessive stress through lack of water or excess water. This note analyses the technique used to apply the water. Two main water application parameters were identified parameter a expressing the mean moisture level of the pot during growing, and parameter b expressing the amplitude of the variation in moisture level between the irrigation threshold and the level to which the water was topped up at each watering. The actual mean volume of irrigation during the cultivation period was compared with the theoretically predicted value and the discrepancy explained. The role of parameter a and b are proposed to define the irrigation regime applied and the water regime as such can be defined by these two parameters a and b, as a general composite index. Furthermore the effect on the biological performance of both parameters a and b were studied obtaining a clearer picture of the effect of the water regime. The role of both parameters, a and b were synthesized in a specific composite index for each individual characteristic of the plant after taking in account the principal causes of their variations

A singular case of cavernous internal carotid artery aneurysm in patient with cavernous sinus syndrome and bacterial meningitis

AbstractWe report the uncommon case of an acute cavernous sinus syndrome in a patient who was consequently discovered to have both a cavernous internal carotid artery aneurysm and bacterial meningitis. Which came first, the chicken or the egg? Which of the two, the aneurysm or the meningitis, gave rise to the patient’s symptoms? We briefly reviewed the literature of similar cases and tried to analyze the possible pathophysiological relationship between these findings. Moreover, this case highlights the importance of a multidisciplinary management of these patients to better decide between a medical and a surgical and/or endovascular treatment

Growing Tomato Plantlets on Various Mixtures of Peat and Sand or Peat and Perlite. Note 1

Given the considerable interest in use of substrates derived from various mixtures in the nursery sector and in light of the enormous variety of possibilities offered by this technique, in contrast with the still small number of researches dedicated to this theme, this study was set out to examine in-depth the growing of tomato plantlets on peat-based substrates. Two series of peat mixtures were produced, one with sand and the other with perlite, with a volume ratio of the other two components with respect to the peat of 1:0, 2.5:1, 1:1 and 1:2.5. Tomato seedlings were cultivated for 30 or 25 days in small perforated pots containing these mixtures. The irrigation was calculated by weighing each pot daily, measuring the water lost by evaporation-transpiration, then just past an established lower threshold value bringing the water back up to a defined upper threshold. Two water regimes were compared in the sand series and three in the perlite series

Very late bioresorbable scaffold thrombosis and reoccurrence of dissection two years later chronic total occlusion recanalization of the left anterior descending artery

We describe the case of a patient presenting with ST-segment elevation myocardial infarction due to very late scaffold thrombosis. The patient was already admitted for an elective percutaneous recanalization of a chronically occluded left anterior descending artery (LAD). The procedure was performed according the sub-intimal tracking and re-entry (STAR) technique with 4 bioresorbable vascular scaffolds implantation. However, even though the coronary flow was preserved at the end of the procedure, the dissected segment was only partially sealed at the distal segment of the LAD. After 18 mo of regular assumption, dual antiplatelet therapy was discontinued for 10 mo before his presentation at the emergency room. This is the first reported case of a very late scaffold thrombosis after coronary chronic total occlusion (CTO) recanalization performed according to the STAR technique. This case raises concerns about the risk of very late scaffold thrombosis after complex CTO revascularization

Bronchial hyperreactivity and spirometric impairment in patients with allergic rhinitis.

Background: The Link between allergic rhinitis and asthma is well known. Bronchial hyperreactivity (BHR) may be present in rhinitics. The present study is aimed at evaluating a large group of subjects suffering from allergic rhinitis alone to investigate the presence of spirometric impairment and BHR both during and outside the pollen season. Methods: 360 rhinitics (subdivided in 3 groups: seasonal, SAR, perennial, PAR, and polysensitized, PolysR) were investigated by spirometry and methacholine challenge. Results: There was a significant seasonal difference concerning the number of rhinitics with impaired FEV1 (p<0.01 for SAR, p<0.02 for PAR, and p<0.03 for PolysR) and FEF25-75 (p<0.05 for SAR, p<0.03 for PAR, and p<0.05 for PolysR) as well as with BHR (p<0.05 for SAR and p<0.03 for PAR). Conclusions: This study evidences that an impairment of spirometric parameters and BHR may be observed in patients with allergic rhinitis alone. Thus, careful evaluation of lower airways should be performed in patients with allergic rhinitis alone

miRNA Signatures in Sera of Patients with Active Pulmonary Tuberculosis.

Several studies showed that assessing levels of specific circulating microRNAs (miRNAs) is a non-invasive, rapid, and accurate method for diagnosing diseases or detecting alterations in physiological conditions. We aimed to identify a serum miRNA signature to be used for the diagnosis of tuberculosis (TB). To account for variations due to the genetic makeup, we enrolled adults from two study settings in Europe and Africa. The following categories of subjects were considered: healthy (H), active pulmonary TB (PTB), active pulmonary TB, HIV co-infected (PTB/HIV), latent TB infection (LTBI), other pulmonary infections (OPI), and active extra-pulmonary TB (EPTB). Sera from 10 subjects of the same category were pooled and, after total RNA extraction, screened for miRNA levels by TaqMan low-density arrays. After identification of "relevant miRNAs", we refined the serum miRNA signature discriminating between H and PTB on individual subjects. Signatures were analyzed for their diagnostic performances using a multivariate logistic model and a Relevance Vector Machine (RVM) model. A leave-one-out-cross-validation (LOOCV) approach was adopted for assessing how both models could perform in practice. The analysis on pooled specimens identified selected miRNAs as discriminatory for the categories analyzed. On individual serum samples, we showed that 15 miRNAs serve as signature for H and PTB categories with a diagnostic accuracy of 82% (CI 70.2-90.0), and 77% (CI 64.2-85.9) in a RVM and a logistic classification model, respectively. Considering the different ethnicity, by selecting the specific signature for the European group (10 miRNAs) the diagnostic accuracy increased up to 83% (CI 68.1-92.1), and 81% (65.0-90.3), respectively. The African-specific signature (12 miRNAs) increased the diagnostic accuracy up to 95% (CI 76.4-99.1), and 100% (83.9-100.0), respectively. Serum miRNA signatures represent an interesting source of biomarkers for TB disease with the potential to discriminate between PTB and LTBI, but also among the other categories

Efficacy of Bacillus clausii spores in the prevention of recurrent respiratory infections in children: a pilot study

Probiotic milk has been previously demonstrated to reduce the number of respiratory infections (RI) among children attending day care centres. Thus, this pilot study was aimed to assess the efficacy and the safety of 3 month treatment with Bacillus clausii in the prevention of recurrent respiratory infections (RRI) in children. Eighty children with RRI were studied: 40 of them were randomly treated with B. clausii for 3 months, and followed up for further 3 months; 40 were included in the control group during the same period. Children treated with B. clausii had shorter duration of RI in comparison with the control group both during the treatment phase (mean 11.7 days vs 14.37; p=0.037) and the follow-up period (mean 6.6 days vs 10.92; p=0.049). This effect was evident also in allergic children during the follow-up. In conclusion, this pilot study provides the first preliminary evidence that B. clausii may exert a significant and persistent impact on RI in children and is safe and well tolerated
