A preliminary assessment of the potential health and genetic impacts of releasing confiscated passerines into the wild : a reduced-risk approach

The illegal capture and trade of wild birds have long been threats to biodiversity. The rehabilitation and release of confiscated animals may be a useful conservation tool in species management. However, differences between populations regarding health (e.g., different pathogens) and adaptation (e.g., local adaptation) must be taken into account, since both can negatively impact the recipient population. In this pilot study, we used two of the most illegally trafficked Brazilian wild passerine species, namely the red-crested cardinal (Paroaria coronata) and green-winged saltator (Saltator similis) as case studies and assessed some of the health threats that the release of confiscated passerines may pose to free-living birds. We also investigated the level of difference in mitochondrial genetic structure among populations living in different ecoregions. Blood, feces, and oropharyngeal swabs from confiscated (n = 115) and free-living (n = 120) passerines from the release sites were tested for the Newcastle disease virus, Salmonella spp., and Mycoplasma gallisepticum. These are considered major avian diseases by the Brazilian National Avian Health Program. We analyzed mtDNA to study the difference in genetic structure between populations using samples from 127 free-living passerines. We found no evidence of the Newcastle disease virus or Salmonella spp. in confiscated or free-living passerines from either species. However, the levels of infection with M. galissepticum detected in our study for red-crested cardinals and green-winged saltators calls for a high degree of caution in captive release programs. The difference in genetic structure between populations occurring in different regions was low, and was not significant between those from the Pampa/Subtropical Grasslands region. These results suggest that it may be possible to establish a cost-effective and sensitive protocol for releasing confiscated songbirds, provided that further genome-wide studies indicate that the functional genetic diversity among (at least some of the) populations is also low

Correlação entre composição isotópica de carbono e traços morfológicos, micromorfológicos, anatômicos e fisiológicos de arroz

The objective of this work was to verify the correlations between carbon isotopic composition and traits of superior rice genotypes. Twenty genotypes were analyzed for morphology, micromorphology, anatomy, physiological performance, and carbon fingerprint. The plots consisted of 500 L plastic boxes sowed with rice, to allow of a plant density of 300 plants per square meter. Plant anatomy and physiological performance were evaluated using a microscope and an infrared gas analyzer, respectively. There is a correlation between rice water use efficiency (r = 0.45) and carboxylation efficiency (r = 0.39).O objetivo deste trabalho foi verificar as correlações entre a composição isotópica de carbono e as características de genótipos superiores de arroz.

Preparation and characterization of polymeric nanoparticles loaded with the flavonoid luteolin, by using factorial design.

Nanoparticles containing luteolin flavonoid were prepared by using interfacial polymer deposition following solvent displacement. The formulation was optimized using factorial design. The parameters studied were the type of polymer [poly(ε-caprolactone) and poly(lactic-co-glycolic acid)], nature oil (isodecyl oleate and oleic acid) and the quantity of luteolin. Nanocapsules and nanospheres were also prepared and evaluated. Colloidal suspensions were characterized by evaluating pH, the particle size, the zeta potential, the morphological aspect and the kinetic release. A new High Performance Liquid Chromatography method was developed and validated in order to quantify luteolin in colloidal suspension allowing the analyses of the absolute recovery, entrapment efficiency and the kinetic release. The luteolin-absolute recovery ranged from 61.6% to 95%; entrapment efficiency was nearly 100% in all formulations and the particle sizes were smaller than 185.5 nm. The nanoparticles prepared with isodecyl oleate show a negative zeta potential. On the other hand, when oleic acid was utilized, the zeta potential was positive. The nanoparticles prepared by using isodecyl oleate have a more perfect spherical shape with a regular surface and form, homogeneity, and lower size dispersion. Nanocapsules and nanospheres have a similar release mechanism of pure diffusion according with Korsmeyer-Peppas’s model

The application of static magnetic stimulation reduces survival of SH-SY5Y neuroblastoma cells

Background/Aim: Central nervous system cancer is still a major public health issue. The effectiveness of treatments is limited and varies depending on the severity of disease. Therefore, there is a demand for the development of novel therapies. Static magnetic stimulation (SMS) emerges as a new therapeutic option. The aim of this study was to evaluate the SMS effects on neuroblastoma cells in culture. Materials and Methods: SH-SY5Y neuroblastoma cells were exposed to 0.3T SMS for 6, 12, 24, 36, 72 h, and 6 days. Cell viability (MTT), cell death (annexin-V/PI staining) and cell cycle (DNA content), cell proliferation (CFSE), autophagy (acridine orange), and total mitochondrial mass (MitoTracker™ Red) were analyzed to establish the cellular response to SMS. Results: The viability of SH-SY5Y cells was reduced after exposure to SMS for 24 h and 6 days (p0.05); however, this effect was not related to cell death or cell cycle arrest (p>0.05). In contrast, the viability of human malignant melanoma (HMV-II) cells, used as a tumoral control, was not affected. In addition, stimulated SH-SY5Y cells presented a decrease in mitochondrial mass at both exposure times and a reduction in autophagy and cell proliferation after 6 days (p<0.05). Conclusion: SMS application appears to be a promising adjuvant therapy for the treatment of neuroblastoma since it decreases the survival of SH-SY5Y neuroblastoma cells

Disparity in the use of Alzheimer's disease treatment in Southern Brazil

Alzheimer's disease (AD) treatment is freely available in the Brazilian public health system. However, the prescription pattern and its associated factors have been poorly studied in our country. We reviewed all granted requests for AD treatment in the public health system in October 2021 in the Rio Grande do Sul (RS) state, Southern Brazil. We performed a spatial autocorrelation analysis with the population-adjusted patients receiving any AD medication as the outcome and correlated it with several socioeconomic variables. 2382 patients with AD were being treated during the period analyzed. The distribution of the outcome variable was not random (Moran's I 0.17562, P <.0001), with the most developed regions having a higher number of patients/100,000 receiving any AD medication. We show that although AD medications are available through the public health system, there is a clear disparity between regions of RS state. Factors related to socioeconomic development partly explain this finding
