Ecology and Diversity of Urban Pine Forest Soil Invertebrates in Rīga, Latvia / Augsnes Bezmugurkaulnieku Bioloģiskā Daudzveidība Urbānajos Priežu Me…

2015

Abstract A study on ecology and diversity of soil invertebrates of urban pine and mixed pine forests was carried out in seven different sampling plots in Rīga during 2014. Ninety eight soil samples were processed and in total, 40 426 specimens were extracted (of them, 25 237 specimens were identified to species level and 15 189 to order level). Indices (abundance, community similarity etc.) characterising faunal diversity and species communities of Rīga city soil fauna were estimated. The most numerous soil invertebrate groups were Collembola, Oribatida and Mesostigmata, accounting for 95% of all collected animals. There was rather high diversity of soil invertebrates in the disturbed urban…

Life forms, life strategies and ecological indices of bryophytes for bioindication in wood areas: a case of study in the "Bosco della Ficuzza, Rocca …

2015

Life forms, life strategies and ecological indices of bryophytes which live in evergreen and deciduous Quercus woods as well as in a Pinus halepensis artificial system within the "Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere e Gorgo del Drago" Oriented Nature Reserve are analysed and compared. The study highlights that in the same local climatic conditions the Quercus and Pinus trees select different bio-ecological types in the bryophyte communities. They appear to be especially useful to detect physionomic-structural differences in the woods, integrating the information provided by the ecological indices

Subcutaneous Veins Depth Estimation Method Using Monte Carlo Simulations

2015

International audience; Subcutaneous veins localization is basic and important step for any intravenous medication administration. Due to different physiological characteristics, mainly darker skin tone, scars or dehydrated condition of patients, medical staff face difficulty in veins localization. Through near infrared imaging technology the veins can be visualized due to high contrast between veins and skin tissue in this modality. Information on the depth of veins is equally important for proper catheterization or venipuncture procedures. Patients have different veins depth due to the different amount of fat present in the subcutaneous layer. The depth of veins from the skin surface cann…

Bedside surgery in the newborn infants: Survey of the Italian society of pediatric surgery

2020

Abstract Introduction This is the report of the first official survey from the Italian Society of Pediatric Surgery (ISPS) to appraise the distribution and organization of bedside surgery in the neonatal intensive care units (NICU) in Italy. Methods A questionnaire requesting general data, staff data and workload data of the centers was developed and sent by means of an online cloud-based software instrument to all Italian pediatric surgery Units. Results The survey was answered by 34 (65%) out of 52 centers. NICU bedside surgery is reported in 81.8% of the pediatric surgery centers. A lower prevalence of bedside surgical practice in the NICU was reported for Southern Italy and the islands …

Endogenous and exogenous nitric oxide inhibits norepinephrine release from rat heart sympathetic nerves.

1995

Abstract This study was designed to elucidate whether nitric oxide (NO) controls norepinephrine (NE) release from sympathetic nerves of the rat heart. Hearts were perfused in the Langendorff mode with Tyrode’s solution. The right sympathetic nerve was stimulated with trains of 1 or 3 Hz and NE release was measured. The NO synthase (NOS) inhibitor N G -nitro- l -arginine (L-NNA) enhanced the evoked NE release in a concentration-dependent manner. This facilitation was independent of the increase in perfusion pressure and was stereospecifically reversed by l -arginine but not d -arginine. Another NOS inhibitor, N G -methyl- l -arginine, produced a similar increase in NE release. The NO-donor …

Substance use, medication adherence and outcome one year following a first episode of psychosis

2016

Both substance use and poor medication adherence are associated with poor outcome in psychosis. To clarify the contributions of substance use and poor medication adherence to poor outcome in the year following a first episode of psychosis, 205 patients were evaluated for use of tobacco, alcohol, cannabis and stimulants at their psychosis onset, and in a 1-year follow-up. Data on medication adherence and symptom remission were also collected. Patients had high rates of overall substance use before (37-65%) and after psychosis onset (45-66%). 44% showed poor medication adherence and 55% did not reach remission from psychosis. Nicotine dependence and cannabis use after psychosis onset signific…

Radioimmunoassay of Plasma and Urinary Norepinephrine

1989

Various analytical methods, such as fluorimetry, radioenzymic assay and in particular liquid chromatography are used for the analysis of norepinephrine (NA) in body fluids and tissue homogenates. These procedures, however, often lack sensitivity, are expensive and/or time consuming. Basing on our previous reports on the radioimmunoassay of chemically modified serotonin1, 5-hydroxy-3-indole acetic acid2 and normetanephrine (NMN)3, a sensitive radioimmunoassay of the N-acetyl,3-methoxy analogue of urinary and plasma norepinephrine was developed.

Course of weight gain and metabolic abnormalities in first treated episode of psychosis: the first year is a critical period for development of cardi…

2014

Data on the long-term metabolic side-effects associated with antipsychotics are scarce. Prospective longitudinal studies in medication-naive patients with a first episode of psychosis are a valuable source of information as they provide an assessment prior to the antipsychotic exposure and minimize the effect of potential confounding factors. The aim of this study was to assess the course of weight gain and the incidence of metabolic abnormalities during the first 3 yr of antipsychotic treatment. Data were collected from a cohort of 170 first-episode psychosis patients. They were randomly assigned to haloperidol (32%); olanzapine (32%) and risperidone (36%). The dose used was flexible. The …
