Predicting cyanobacterial biovolume from water temperature and conductivity using a Bayesian compound Poisson-Gamma model.

Eutrophication and climate change scenarios engender the need to develop good predictive models for harmful cyanobacterial blooms (CyanoHABs). Nevertheless, modeling cyanobacterial biomass is a challenging task due to strongly skewed distributions that include many absences as well as extreme values (dense blooms). Most modeling approaches alter the natural distribution of the data by splitting them into zeros (absences) and positive values, assuming that different processes underlie these two components.

'Candidatus Liberibacter asiaticus', Causal Agent of Citrus Huanglongbing, Is Reduced by Treatment with Brassinosteroids.

Huanglongbing (HLB) constitutes the most destructive disease of citrus worldwide, yet no established efficient management measures exist for it. Brassinosteroids, a family of plant steroidal compounds, are essential for plant growth, development and stress tolerance. As a possible control strategy for HLB, epibrassinolide was applied to as a foliar spray to citrus plants infected with the causal agent of HLB, 'Candidatus Liberibacter asiaticus'.

Current imaging follow-up of non-Hodgkin lymphoma exposes patients to significant radiation but does not detect asymptomatic relapses.

The standard approach to the follow-up of lymphoma includes computed tomography (CT) every 6-12 months for the first 2 years and, then, as clinically indicated. Recent evidence suggests that most relapses are detected clinically, outside scheduled CT which, on the other hand, increases risk of second malignancies and cost. In early-stage lymphomas, involved site CT instead of full body CT may be a reasonable alternative to reduce radiation dose.

Space-time dynamics of stem cell niches: a unified approach for plants.

Many complex systems cannot be analyzed using traditional mathematical tools, due to their irreducible nature. This makes it necessary to develop models that can be implemented computationally to simulate their evolution. Examples of these models are cellular automata, evolutionary algorithms, complex networks, agent-based models, symbolic dynamics and dynamical systems techniques.

Utilization of the supports intensity scale with psychiatric populations: psychometric properties and utility for service delivery planning.

In agreement with the new paradigm of supports, this study examines the adequacy and psychometric properties of the Supports Intensity Scale (SIS) in a sample of 182 participants with severe mental illness (mean Global Assessment of Functioning [GAF] score = 60.2). The measure focuses on identifying the profile and intensities of support needs and on the planning and service delivery rather than on weaknesses and limitations.

Doxazosin blockade of alpha 1-adrenergic receptors increases rat serum progesterone levels: a putative role of ovarian angiotensin III in steroidogenesis.

Objective: To analyze the role of the local renin-angiotensin system (RAS) in the female reproductive system to modulate ovarian steroidogenesis and its relationship with alpha(1)adrenergic receptors.

Design: Observational study.

Setting: University laboratory.

Adsorption isotherm of CO on Pt(111) electrodes.

We have determined, for the first time, the equilibrium CO coverage of Pt(111) electrodes at room temperature in 0.1 M H(2)SO(4) as a function of the CO partial pressure using CO-stripping cyclic voltammetry. Fourier-transform infrared (FT-IR) spectroscopy was used to confirm qualitatively the coverage values obtained.

Specific enkephalin-degrading aminopeptidase activity in the HPT and HPO axes of rats with breast cancer induced by N-methyl nitrosourea.

State and function of breast depend on an endocrinological balance, the upsetting of which can be a factor favorable to the development of cancer. Enkephalins (ENK) have been considered as a particular form of adaptation to defense to the organism against neoplastic processes. However, ENK may modify the endocrine functions of glands such as the ovary or the thyroid through the hypothalamus-pituitary axis, acting direct or indirectly as endocrine, paracrine or autocrine stimulatory growth factors.
