Agrobiodiversity Products by SWOT Analysis as an Analysis for Strategic Innovation
The paper aimed to demonstrate the potential of agro-biodiversity products derived from medicinal plants of the family farmers in Profito network (specific program of the Brazilian government). Method used was scenarios analysis of the knowledge. Literature review it was in the scientific database. According to the new "green wave" created by contemporary society aiming a better health and quality of life by population, it led to the depredation of medicinal species due to the acceleration of global trade demand. Thus, was constructed a SWOT analysis to support managers in strategic planning through of the potential agro-biodiversity products. It shows the appreciation of environmentally conscious products, economically sustainable and the creation of new public policies that ensure and valuation to the rescue, conservation and sustainable use of biodiversity since they are essential for building this niche market
Correction of negative dysphotopsia in Crystalens “Z syndrome”
We report a case of negative dysphotopsia in the left eye of a 56-year-old
patient three months after uneventful bilateral phacoemulsification and implantation of a
Crystalens® intraocular lens (Bausch and Lomb®) placed in the capsular bag. Three months
postoperatively, the patient described visual field loss in the inferior temporal quadrant in
the left eye under low light conditions. Anterior capsulorhexis was eccentric, allowing the
inferior temporal optic edge to move forward, producing late asymmetric vault of the lens.
One month later, when the equatorial diameter of the capsular bag decreased, we pushed the
inferior temporary hinge backwards so that the lens moved back into the correct position.
Six months after relocation, the lens position remained stable and negative dysphotopsia was
absent. This case shows Crystalens Z syndrome as a new etiology of negative dysphotopsia,
and a successful novel treatment in a patient without capsular fibrosis
Effects of high-volume, rapid-fluid therapy on cardiovascular function and hematological values during isoflurane-induced hypotension in healthy dogs
The objective of this study was to determine the effects of the administration of a high volume of isotonic crystalloid at a rapid
rate on cardiovascular function in normovolemic, isoflurane-anesthetized dogs during induced hypotension.
Using a prospective study, 6 adult dogs were induced to general anesthesia and cardiovascular and hematological values were
measured while the dogs were maintained at 3 hemodynamic states: first during light anesthesia with 1.3% end-tidal isoflurane
(ETI); then during a hypotensive state induced by deep anesthesia with 3% ETI for 45 min while administered 1 mL/kg body
weight (BW) per minute of isotonic fluids; and then decreased to 1.6% ETI while receiving 1 mL/kg BW per minute of fluids for
15 min. End-tidal isoflurane (ETI) at 3.0 6 0.2% decreased arterial blood pressure (ABP), cardiac index (CI), and stroke volume
index (SVI), and increased stroke volume variation (SVV) and central venous pressure (CVP). Fluid administration during 3%
ETI decreased only SVV and systemic vascular resistance index (SVRI), while CVP increased progressively. Decreasing ETI to
1.6 6 0.1% returned ABP and SVI to baseline (ETI 1.3 6 0.1%), while CI and heart rate increased and SVV decreased. There was
significant progressive clinical hemodilution of hemoglobin (Hb), packed cell volume (PCV), total protein (TP), colloid osmotic
pressure (COP), arterial oxygen content (CaO2), and central-venous oxygen content (CcvO2).
High-volume, rapid-rate administration of an isotonic crystalloid was ineffective in counteracting isoflurane-induced
hypotension in normovolemic dogs at a deep plane of anesthesia. Cardiovascular function improved only when anesthetic depth
was reduced. Excessive hemodilution and its adverse consequences should be considered when a high volume of crystalloid
is administered at a rapid rate.Cette étude visait à déterminer les effets de l’administration d’un grand volume de cristalloïde isotonique à un débit rapide sur la fonction
cardio-vasculaire de chiens normo-volémique, anesthésiés à l’isoflurane et en hypotension induite.
Dans une étude prospective, 6 chiens adultes ont été soumis à une anesthésie générale et des données cardio-vasculaires et hématologiques
ont été prises pendant que les chiens étaient maintenus à 3 états hémodynamiques : premièrement durant l’anesthésie légère avec 1,3 %
d’isoflurane en phase télo-expiratoire (ETI); par la suite durant un état d’hypotension induit par une anesthésie profonde avec une ETI de
3 % pour 45 min alors que l’on administrait des fluides isotoniques à raison de 1 mL/kg de poids corporel (BW) par minute; et finalement
après réduction de l’ETI à 1,6 % tout en recevant 1 mL/kg de BW par minute de fluide pendant 15 min. L’isoflurane à 3,0 6 0,2 % lors de
l’ETI a entraîné une diminution de la pression sanguine artérielle (ABP), de l’index cardiaque (CI), et de l’index du débit systolique (SVI),
et une augmentation de la variation du volume systolique (SVV) et de la pression veineuse centrale (CVP). L’administration de fluide
durant l’ETI de 3 % a diminué uniquement la SVV et l’index de résistance vasculaire systémique (SVRI), alors que la CVP augmentait
progressivement. La diminution de l’ETI à 1,6 6 0,1 % a ramené l’ABP et le SVI aux valeurs de base (ETI 1,3 6 0,1 %), alors que le CI et
le rythme cardiaque augmentèrent et la SVV diminua. Il y eu une hémodilution clinique progressive significative de l’hémoglobine (Hb),
de l’hématocrite (PCV), des protéines totales (TP), de la pression osmotique colloïdale (COP), du contenu artériel en oxygène (CaO2), et du
contenu veineux central en oxygène (CcvO2).
L’administration rapide d’un grand volume d’un cristalloïde isotonique était inefficace pour contrecarrer une hypotension induite par
l’isoflurane chez des chiens normo-volémique dans un stade profond d’anesthésie. La fonction cardio-vasculaire ne s’est améliorée uniquement
que lorsque la profondeur de l’anesthésie fut réduite. Une hémodilution excessive et ses conséquences néfastes devraient être considérées
lorsqu’un grand volume de cristalloïde est administré à un débit rapide.This paper was presented at the 16th International Veterinary Emergency and Critical Care Symposium and Annual Conference of the American

Dermatomiositis como síndrome paraneoplásico
Inflammatory myopathies have an increased risk of malignancy, the one with the highest association being dermatomyositis. The neoplasm can be solid or hematologic. There are clinical and laboratory factors that can increase or decrease the risk for the presentation of a myositis as a paraneoplastic disease. Among the main risk factors, the presence of anti-TIF1, anti-NXP2 and to a lesser extent anti-SAE antibodies have been observed. The main theory of its origin points to the immune response derived from the creation of mutated proteins by cancer cells. The diagnosis of malignancy can be made before, during or after the diagnosis of dermatomyositis. There is no established therapeutic regimen, however the use of steroids, immunosuppressants or immunoglobulins have been proposed, as well as effective cancer therapy.Las miopatías inflamatorias tienen un riesgo aumentado de malignidad, siendo la dermatomiositis la de mayor asociación. La neoplasia puede ser sólida o hematológica. Existen factores clínicos y de laboratorio que pueden aumentar o disminuir el riesgo de presentación de miositis como enfermedad paraneoplásica. Entre los principales factores de riesgo, se ha observado la presencia de anticuerpos anti-TIF1, el anti-NXP2 y en menor medida el anti-SAE. La principal teoría de su origen apunta hacia la respuesta inmune derivada de la creación de proteínas mutadas por parte de las células cancerosas. El diagnóstico de malignidad se puede realizar antes, durante o después del diagnóstico de dermatomiositis. No existe un régimen terapéutico establecido, sin embargo se ha propuesto el uso de esteroides, inmunosupresores o inmunoglobulinas, así como la terapia efectiva contra el cáncer
Influence of the number of daily pills and doses on adherence to antiretroviral treatment: a 7-year study
[EN] What is known and objective: Antiretroviral treatment (ART) is hampered by complicated regimens, high pill burden, drug–drug interactions, and frequent short- and long-term adverse effects, leading to decreased adherence. Over recent years, considerable effort has been directed at developing regimens
that are less burdening. We undertook a 7-year retrospective study of the records of 264 HIV-infected subjects enrolled in a pharmaceutical care programme to document the progress made and to study the influence of the number of ART pills and doses on the level of treatment adherence.
Methods: Antiretroviral dispensing records were analysed for the number of pills and doses administered and the ART adherence rate estimated.
Results and discussion: In 2005, the patients took a mean of 6 2 pills daily (CI 95%: 5 9–6 6), and 92 9% of them were on a twice-a-day (BID) dosage regimen. By 2012, the mean number of pills was reduced to 4 1 (CI 95%: 3 8–4 4), and only 50 9% were on a BID regimen. No statistically significant relation was observed between number of daily pills and doses and ART adherence reached by the patients in any of the analyses performed.
What is new and conclusions: There has been a continuous reduction in the number of pills and doses of antiretrovirals taken by individual patients over the last 7 years due largely to the introduction of improved treatments and regimens. More daily pills or doses was not associated with worse ART adherence in our pharmaceutical care programme
Padrão e extremos de precipitação na cidade de São Paulo
The objective of this study is to analyze the precipitation variability, extreme events, and trends of this variable in the city of São Paulo. The data used covered the period between 1933 and 2020, originating from the IAG/USP Meteorological Station. The monthly averages for the study of seasonality, the boxplot diagram for the investigation of rare monthly events, and the quantile technique for classifying extreme precipitation events were considered for analysis. A trend analysis was performed through the accumulated annual precipitation and linear adjustment by a simple linear regression equation. In seasonal terms, the city of São Paulo has low precipitation in winter, with a minimum in August and an average of 38.05 mm, increasing total precipitation during spring. It was observed that the highest precipitation values occurred during the summer, with a peak in January and 232.14 mm. According to the boxplot diagram, the rare events of high precipitation occur mainly in winter, with emphasis on May and June. There is a greater concentration of extreme precipitation events in the second half of the observed years. The dry months have the highest occurrences of rare precipitation events. Simple linear regression analysis indicated a positive trend, indicating an average increase in annual precipitation of 508.43 mm in the city of São Paulo. In general, there is an indication of an precipitation increase in the city, especially due to the higher frequency of monthly extreme rainy events.

Toward a Coordinated Understanding of Hydro-Biogeochemical Root Functions in Tropical Forests for Application in Vegetation Models
Tropical forest root characteristics and resource acquisition strategies are underrepresented in vegetation and global models, hampering the prediction of forest–climate feedbacks for these carbon-rich ecosystems. Lowland tropical forests often have globally unique combinations of high taxonomic and functional biodiversity, rainfall seasonality, and strongly weathered infertile soils, giving rise to distinct patterns in root traits and functions compared with higher latitude ecosystems. We provide a roadmap for integrating recent advances in our understanding of tropical forest belowground function into vegetation models, focusing on water and nutrient acquisition. We offer comparisons of recent advances in empirical and model understanding of root characteristics that represent important functional processes in tropical forests. We focus on: (1) fine-root strategies for soil resource exploration, (2) coupling and trade-offs in fine-root water vs nutrient acquisition, and (3) aboveground–belowground linkages in plant resource acquisition and use. We suggest avenues for representing these extremely diverse plant communities in computationally manageable and ecologically meaningful groups in models for linked aboveground–belowground hydro-nutrient functions. Tropical forests are undergoing warming, shifting rainfall regimes, and exacerbation of soil nutrient scarcity caused by elevated atmospheric CO2. The accurate model representation of tropical forest functions is crucial for understanding the interactions of this biome with the climate

The All-sky Medium Energy Gamma-ray Observatory eXplorer (AMEGO-X) Mission Concept
The All-sky Medium Energy Gamma-ray Observatory eXplorer (AMEGO-X) is
designed to identify and characterize gamma rays from extreme explosions and
accelerators. The main science themes include: supermassive black holes and
their connections to neutrinos and cosmic rays; binary neutron star mergers and
the relativistic jets they produce; cosmic ray particle acceleration sources
including Galactic supernovae; and continuous monitoring of other astrophysical
events and sources over the full sky in this important energy range. AMEGO-X
will probe the medium energy gamma-ray band using a single instrument with
sensitivity up to an order of magnitude greater than previous telescopes in the
energy range 100 keV to 1 GeV that can be only realized in space. During its
three-year baseline mission, AMEGO-X will observe nearly the entire sky every
two orbits, building up a sensitive all-sky map of gamma-ray sources and
emission. AMEGO-X was submitted in the recent 2021 NASA MIDEX Announcement of
Opportunity.Comment: 23 pages, 16 figures, Published Journal of Astronomical Telescopes,

Rapid responses of root traits and productivity to phosphorus and cation additions in a tropical lowland forest in Amazonia
• Soil nutrient availability can strongly affect root traits. In tropical forests, phosphorus (P) is often considered the main limiting nutrient for plants. However, support for the P paradigm is limited, and N and cations might also control tropical forests functioning.
• We used a large‐scale experiment to determine how the factorial addition of nitrogen (N), P and cations affected root productivity and traits related to nutrient acquisition strategies (morphological traits, phosphatase activity, arbuscular mycorrhizal colonisation and nutrient contents) in a primary rainforest growing on low‐fertility soils in Central Amazonia after one year of fertilisation.
• Multiple root traits and productivity were affected. Phosphorus additions increased annual root productivity and root diameter, but decreased root phosphatase activity. Cation additions increased root productivity at certain times of year, also increasing root diameter and mycorrhizal colonisation. P and cation additions increased their element concentrations in root tissues. No responses were detected with N addition.
• Here we show that rock‐derived nutrients determine root functioning in low‐fertility Amazonian soils, demonstrating not only the hypothesised importance of P, but also highlighting the role of cations. The changes in fine root traits and productivity indicate that even slow‐growing tropical rainforests can respond rapidly to changes in resource availability
