Design and Construction of a New Metering Hot Box for the In Situ Hygrothermal Measurement in Dynamic Conditions of Historic Masonries

The main purpose of the HeLLo project is to contribute to data available on the literature on the real hygrothermal behavior of historic walls and the suitability of insulation technologies. Furthermore, it also aims at minimizing the energy simulation errors at the design phase and at improving their conservation features. In this framework, one of the preliminary activities of the study is the creation of a real in situ hot box to measure and analyze different insulation technologies applied to a real historic wall, to quantify the hygrothermal performance of a masonry building. Inside this box, ‘traditional’ experiments can be carried out: recording heat flux, surface temperature, and air temperatures, as well as relative humidity values through the use of a new sensing system (composed of thermocouples and temperature/relative humidity combined sensors). Within this paper, the process of development, construction, and validation of this new metering box is exhibited. The new hot box, specifically studied for historic case studies, when compared to other boxes, presents other advantages compared to previous examples, widely exemplified

Effect of bioactive compounds released from Brassicaceae defatted seed meals on bacterial load in pig manure.

Animal manure application to soils is considered to be one of the main cause of antibiotic and bacterial pathogen spread in the environment. Pig livestock, which is the source of one of the most used fertilizer for cultivated land, is also a hotspot for antibiotics and antibiotic-resistant bacteria. Besides harsh chemical and physical sanitization treatments for the abatement of antibiotics and bacterial load in livestock waste, more sustainable and environmentally friendly strategies need to be considered. In this context, the use of natural substances which are proved useful for pest and disease control is currently under exploration for their role in the reduction of bacterial pathogen population. Among these, plants and derived products from the Brassicaceae family, characterized by the presence of a defensive glucosinolate-myrosinase enzymatic system, have been successfully exploited for years in agriculture using the so-called biofumigation technique against crop diseases. Although the application of biofumigation to suppress a range of soil borne pests has been well documented, no studies have been examined to reduce bacterial population in animal waste. In the present study, the release and the antibacterial activity of bioactive compounds deriving from different Brassicaceae defatted seed meals against pathogens and bacterial population in pig manure is addressed. Rapistrum rugosum and Brassica nigra defatted seed meals were found to be the most active products against tested pathogens and able to significantly reduce the bacterial load in the manure

Preliminary test results on the new electronic readout of the YAP(S)PET small animal scanner

A small animal PET-SPECT scanner (YAP-(S)PET) prototype was built at the Physics Department of the University of Ferrara and is presently being used at the Nuclear Medicine Department for radiopharmaceutical studies on rats. The first YAP-(S)PET prototype shows very good performances, but needs some improvements before it can be used for intensive radiopharmaceutical research. The main problem of the actual prototype is its heavy electronics, based on NIM and CAMAC standard modules. For this reason a new, compact readout electronics was developed and tested. The results of a first series of tests made on the first prototype will be presented in this paper

Skeletal muscle structure and function in response to electrical stimulation in moderately impaired COPD patients

Study objective: To determine the structural and functional consequences of high-frequency neuromuscular electrical stimulation (hf-NMES) in a group of moderately impaired outpatients with chronic obstructive pulmonary disease (COPD).Design: A prospective, cross-over randomized trial.Setting: An university-based, tertiary center.Patients and materials: Seventeen patients (FEV1 = 49.6 +/- 13.4% predicted, Medical Research Council dyspnoea grades II-III) underwent 6-weeks hf-NMES (50 Hz) and sham stimulation of the quadriceps femoris in a randomized, cross-over design. Knee strength was measured by isokinetic dynamometry (peak torque) and leg muscle mass (LMM) by DEXA; in addition, median cross-sectional area (CSA) of type I and fibres and capillary-fibre ratio were evaluated in the vastus lateralis. the 6-min walking distance (6MWD) was also determined.Universidade Federal de São Paulo, UNIFESP, Pulm Funct & Clin Exercise Physiol Unit, SEFIC,Div Resp Dis,Dept Med, São Paulo, BrazilUniversidade Federal de São Paulo, UNIFESP, Neuromusc Div, São Paulo, BrazilUniv Glasgow, Inst Biomed & Life Sci, Glasgow, Lanark, ScotlandUniversidade Federal de São Paulo, UNIFESP, Pulm Funct & Clin Exercise Physiol Unit, SEFIC,Div Resp Dis,Dept Med, São Paulo, BrazilUniversidade Federal de São Paulo, UNIFESP, Neuromusc Div, São Paulo, BrazilWeb of Scienc

Uterine cavity embryonal rhabdomyosarcoma

Rhabdomyosarcoma (RMS) is a rare solid tumor in childhood and adolescence. The higher incidence is predominant during the first two decades of life. According to the Intergroup RMS Study Group, the embryonal RMS (ERMS), botryoidal variant, constitutes a histological subtype characterized as a “grape-like” lesion of 2.0 cm to 9.5 cm. The treatment involves chemotherapy, surgery, and/or radiotherapy. We present the case of a 14-year-old female patient diagnosed with ERMS, botryoidal variant, which originated in the uterine cervix with vaginal externalization. The initial therapeutic approach comprised an initial prolapsed mass excision followed by Wertheim–Meigs surgery due to the tumor extension. No consensual protocol to ERMS treatment is found in the medical literature; however, a combined approach seems to offer a better result. The postoperative time period was uneventful and the patient followed an adjuvant therapy with vincristine, d-actinomycin, and cyclophosphamide. A comprehensive evaluation of the therapeutic options preserving the reproductive function—unfortunately not always possible—is part of a multi-disciplined care team concerning the pediatric patients

CLARO-CMOS, an ASIC for single photon counting with Ma-PMTs, MCPs and SiPMs

An ASIC named CLARO-CMOS was designed for fast photon counting with MaPMTs, MCPs and SiPMs. The prototype was realized in a .35 μm CMOS technology and has four channels, each with a fast amplifier and a discriminator. The main features of the design are the high speed of operation and the low power dissipation, below 1 mW per channel. This paper focuses on the use of the CLARO for SiPM readout. The ASIC was tested with several SiPMs of various sizes, connected to the input of the chip both directly and through a coaxial cable about one meter long. In the latter case the ASIC is still fully functional although the speed of response is affected by the cable capacitance. The threshold could be set just above the single photoelectron level, and with 1 ×1 mm 2 SiPMs the discrete photoelectron peaks could be well resolve

Clinical correlates of “pure” essential tremor: the TITAN study

BackgroundTo date, there are no large studies delineating the clinical correlates of “pure” essential tremor (ET) according to its new definition.MethodsFrom the ITAlian tremor Network (TITAN) database, we extracted data from patients with a diagnosis of “pure” ET and excluded those with other tremor classifications, including ET-plus, focal, and task-specific tremor, which were formerly considered parts of the ET spectrum.ResultsOut of 653 subjects recruited in the TITAN study by January 2022, the data of 208 (31.8%) “pure” ET patients (86M/122F) were analyzed. The distribution of age at onset was found to be bimodal. The proportion of familial cases by the age-at-onset class of 20 years showed significant differences, with sporadic cases representing the large majority of the class with an age at onset above 60 years. Patients with a positive family history of tremor had a younger onset and were more likely to have leg involvement than sporadic patients despite a similar disease duration. Early-onset and late-onset cases were different in terms of tremor distribution at onset and tremor severity, likely as a function of longer disease duration, yet without differences in terms of quality of life, which suggests a relatively benign progression. Treatment patterns and outcomes revealed that up to 40% of the sample was unsatisfied with the current pharmacological options.DiscussionThe findings reported in the study provide new insights, especially with regard to a possible inversed sex distribution, and to the genetic backgrounds of “pure” ET, given that familial cases were evenly distributed across age-at-onset classes of 20 years. Deep clinical profiling of “pure” ET, for instance, according to age at onset, might increase the clinical value of this syndrome in identifying pathogenetic hypotheses and therapeutic strategies

Associations between depressive symptoms and disease progression in older patients with chronic kidney disease: results of the EQUAL study

Background Depressive symptoms are associated with adverse clinical outcomes in patients with end-stage kidney disease; however, few small studies have examined this association in patients with earlier phases of chronic kidney disease (CKD). We studied associations between baseline depressive symptoms and clinical outcomes in older patients with advanced CKD and examined whether these associations differed depending on sex. Methods CKD patients (>= 65 years; estimated glomerular filtration rate <= 20 mL/min/1.73 m(2)) were included from a European multicentre prospective cohort between 2012 and 2019. Depressive symptoms were measured by the five-item Mental Health Inventory (cut-off <= 70; 0-100 scale). Cox proportional hazard analysis was used to study associations between depressive symptoms and time to dialysis initiation, all-cause mortality and these outcomes combined. A joint model was used to study the association between depressive symptoms and kidney function over time. Analyses were adjusted for potential baseline confounders. Results Overall kidney function decline in 1326 patients was -0.12 mL/min/1.73 m(2)/month. A total of 515 patients showed depressive symptoms. No significant association was found between depressive symptoms and kidney function over time (P = 0.08). Unlike women, men with depressive symptoms had an increased mortality rate compared with those without symptoms [adjusted hazard ratio 1.41 (95% confidence interval 1.03-1.93)]. Depressive symptoms were not significantly associated with a higher hazard of dialysis initiation, or with the combined outcome (i.e. dialysis initiation and all-cause mortality). Conclusions There was no significant association between depressive symptoms at baseline and decline in kidney function over time in older patients with advanced CKD. Depressive symptoms at baseline were associated with a higher mortality rate in men
