Abstract
BACKGROUND
Psychiatric patients are often kept immobilized during hospitalization to avoid self-inflicted injuries and danger to third parties. Inadequate positioning can lead to brachial ...plexus injuries (BPI).
OBJECTIVE
To present a series of 5 psychiatric patients with BPI after being left sedated and restrained for prolonged periods of time during hospitalization.
METHODS
We retrospectively reviewed the charts of 5 psychiatric patients with iatrogenic BPI referred by other institutions to our service. The restraint technique adopted by those institutions consisted of a high-thoracic restraint. All patients underwent complete clinical and neurological examination at our center. Information concerning patient demographics, BPI characteristics, treatment choice, and ultimate outcome was recorded.
RESULTS
Three patients were male. The age of our patients ranged from 25 to 61 years old (mean: 41.2; median: 43). Three patients had a diagnosis of bipolar disorder while 2 had schizophrenia. Duration of immobilization ranged from 5 to 168 h (mean: 77.8; median: 72). Four patients presented with a unilateral right-sided lesion. Time to presentation ranged from 1 to 9 mo (mean: 4.2; median: 4). All patients also had intense pain and axillary lesions. Four patients received conservative treatment with partial or full functional recovery and complete pain resolution. The remaining patients underwent surgical repair and experienced good functional outcome.
CONCLUSION
Psychiatric patients who need to be sedated and immobilized must be monitored closely, as BPI can occur from high-thoracic restraints. When such an injury occurs, the patient must be referred to a center specialized in peripheral nerve surgery and rehabilitation.
The objective of this work is to evaluate the concentration of cyanogenic glycosides CGs (amygdalin and prunasin) in the cultivar and rootstock, as an indicator of compatibility in pear grafts. The ...work consists of two experiments. Experiment 1 evaluated Cascatense/Pyrus Calleryana and Cascatense/EMC combinations. Experiment 2 evaluated the combinations Packham’s Triumph/Adams, Santa Maria/Adams, and Rocha/Adams. The experimental design of the two experiments was randomized blocks with four replications. The evaluations were carried out in the spring and summer of the harvest 2014/2015. The results indicated graft compatibility in the Cascatense/P. Calleryana, Packham’s Triumph/Adams, and Rocha/Adams combinations; slight incompatibility of Santa Maria/Adams, and severe incompatibility of Cascatense/EMC. The obtained results indicate that differences ≥ 20 mg g-1 of CGs between scion and rootstock were correlated with a drastic reduction in vigor, problems of continuity in graft union, low yield, and early defoliation.

The map named
Carta Geographica de Projecçaõ Espherica Orthogonal da Nova Lusitania ou America Portugueza e Estado do Brazil
from 1798, together with its 1795 (?), 1797 and 1803 versions, is ...undoubtedly one of the cartographic monuments developed by Portuguese cartography from the late eighteenth century. Its organizer was the geographer, astronomer, and frigate captain Antonio Pires da Silva Pontes Leme, who relied on the work of 34 people, including astronomers, geographers, and engineers, who, although only mentioned in the 1798 version, contributed to the creation of all versions. All of them are similar in appearance, but differ in size, content, details, amount, and distribution of toponyms, which will be the subject of another paper. The greatest similarity, however, concerns the defined map projection.
The objective of this paper is to analyse and present the possible hypotheses and conclusions about which map projection was adopted for all versions of
Nova Lusitania
, through the identification of characteristics that allowed to infer and prove the adopted projection. The applied methodology verified that in the bibliographic search, the information about the map structure is insufficient. An article presented by General Djalma Polli Coelho in October 1950 states that the projection suggested by its title, as orthogonal spherical, appeared to be the Sanson-Flamsteed equal-area projection. However, the expression
Carta Geographica de Projecçaõ Espherica Orthogonal
allows us to infer also the transverse orthographic projection.
Through parameters defined for the two projections, it was possible to establish the comparative elements for a cartographic analysis, which would allow us to conclude and prove the structure adopted for the map, allowing to conclude if the adopted projection for the
Nova Lusitania
was an azimuthal orthographic equatorial projection, or a Sanson-Flamsteed, sinusoidal projection on the meridian 315°, defined west-east, (counterclockwise), from the El Hierro (Ferro) Island. This meridian is referenced approx. –62°39'46" off the Greenwich meridian.
Carta Geographica de Projecçaõ Espherica Orthogonal da Nova Lusitania ou America Portugueza e Estado do Brazil
iz 1798. godine, zajedno sa svojim inačicama iz 1795. (?), 1797. i 1803. godine, nesumnjivo je jedan od kartografskih spomenika izrađenih u Portugalu krajem osamnaestog stoljeća. Njezin je organizator bio geograf, astronom i kapetan fregate Antonio Pires da Silva Pontes Leme koji se oslanjao na rad 34 osobe, uključujući astronome, geografe i inženjere, koji su, iako samo spomenuti u inačici iz 1798. godine, pridonijeli izradi svih drugih.
Sve su inačice izgledom slične, ali se razlikuju po veličini, sadržaju, detaljima, količini i distribuciji toponima, no to će biti predmet drugoga rada. Međutim, najveća se sličnost odnosi na kartografsku projekciju.
Cilj je ovoga rada analizirati i prikazati moguće hipoteze i zaključke o tome koja je kartografska projekcija usvojena za sve inačice
Nove Luzitanije
identificiranjem karakteristika koje su omogućile zaključivanje i dokazivanje usvojene projekcije.
Primijenjena je metodologija potvrdila da su u bibliografskom pretraživanju podatci o strukturi karte nedovoljni. U članku koji je u listopadu 1950. predstavio general Djalma Polli Coelho navodi se da se čini da je projekcija predložena naslovom kao ortogonalna sferna projekcija zapravo ekvivalentna Sanson-Flamsteedova projekcija. Međutim, naslov
Carta Geographica de Projecçaõ Espherica Orthogonal
omogućuje nam zaključak da je to možda poprečna ortografska projekcija sfere.
S pomoću parametara koji definiraju dvije projekcije bit će moguće uspostaviti usporedne elemente za kartografsku analizu, što bi nam omogućilo da zaključimo i dokažemo strukturu usvojenu za kartu
Nova Lusitanija
– je li ona poprečna ortografska projekcija ili Sanson-Flamsteedova sinusna projekcija sa srednjim meridijanom od 315°, definiranim u smjeru zapad-stok (u smjeru suprotnom od kazaljke na satu) s otoka El Hierro (Ferro). Taj je meridijan smješten približno –62°39ʹ46ʺ u odnosu na grinički meridijan.
Malaria associated-acute kidney injury (AKI) is associated with 45% of mortality in adult patients hospitalized with severe form of the disease. However, the causes that lead to a framework of ...malaria-associated AKI are still poorly characterized. Some clinical studies speculate that oxidative stress products, a characteristic of Plasmodium infection, as well as proinflammatory response induced by the parasite are involved in its pathophysiology. Therefore, we aimed to investigate the development of malaria-associated AKI during infection by P. berghei ANKA, with special attention to the role played by the inflammatory response and the involvement of oxidative stress. For that, we took advantage of an experimental model of severe malaria that showed significant changes in the renal pathophysiology to investigate the role of malaria infection in the renal microvascular permeability and tissue injury. Therefore, BALB/c mice were infected with P. berghei ANKA. To assess renal function, creatinine, blood urea nitrogen, and ratio of proteinuria and creatininuria were evaluated. The products of oxidative stress, as well as cytokine profile were quantified in plasma and renal tissue. The change of renal microvascular permeability, tissue hypoxia and cellular apoptosis were also evaluated. Parasite infection resulted in renal dysfunction. Furthermore, we observed increased expression of adhesion molecule, proinflammatory cytokines and products of oxidative stress, associated with a decrease mRNA expression of HO-1 in kidney tissue of infected mice. The measurement of lipoprotein oxidizability also showed a significant increase in plasma of infected animals. Together, our findings support the idea that products of oxidative stress, as well as the immune response against the parasite are crucial to changes in kidney architecture and microvascular endothelial permeability of BALB/c mice infected with P. berghei ANKA.

Técnicas que melhorem a eficiência do processo e reduzam o custo de operação são importantes ferramentas na redução dos custos. Dois dispositivos mecânicos foram utilizados para testar a eficiência ...no raleio de frutos e flores em pessegueiros e a influencia nas características produtivas e qualitativas dos frutos. O estudo foi realizado na cultivar Maciel em pomar comercial no município de Pelotas, Rio Grande do Sul, Brasil. Os tratamentos foram: raleio mecânico de flores com o equipamento Carpa Electro® e “derriçadeira”, raleio mecânico de frutos com o equipamento “derriçadeira” e raleio manual de frutos. O raleio mecânico associado ao repasse manual em pessegueiros pode ser uma alternativa viável ao raleio manual, pois reduz o tempo de execução desta prática. Os dois equipamentos podem ser utilizados para o raleio mecânico, pois não alteraram a produção por planta, o número de frutos por planta, a massa dos frutos, diâmetro dos frutos, as características físico-químicas e os compostos bioativos dos frutos.

Mosquitoes feed on plant-derived fluids such as nectar and sap and are exposed to bioactive molecules found in this dietary source. However, the role of such molecules on mosquito vectorial capacity ...is unknown. Weather has been recognized as a major determinant of the spread of dengue, and plants under abiotic stress increase their production of polyphenols.
Here, we show that including polyphenols in mosquito meals promoted the activation of AMP-dependent protein kinase (AMPK). AMPK positively regulated midgut autophagy leading to a decrease in bacterial proliferation and an increase in vector lifespan. Suppression of AMPK activity resulted in a 6-fold increase in midgut microbiota. Similarly, inhibition of polyphenol-induced autophagy induced an 8-fold increase in bacterial proliferation. Mosquitoes maintained on the polyphenol diet were readily infected by dengue virus.
The present findings uncover a new direct route by which exacerbation of autophagy through activation of the AMPK pathway leads to a more efficient control of mosquito midgut microbiota and increases the average mosquito lifespan. Our results suggest for the first time that the polyphenol content and availability of the surrounding vegetation may increase the population of mosquitoes prone to infection with arboviruses.
The present study has been carried out to estimate the prevalence of HCV among HIV-positive individuals in the state of Mato Grosso, Central Brazil, as well as to identify the associated ...epidemiological factors. One thousand and eight individuals over 18 years of age bearing HIV/aids and being attended in the reference public health network of the state of Mato Grosso participated in this research. HIV-positive subjects were interviewed and blood samples were taken to be tested for anti-HCV antibodies by enzyme immunoassay (EIA). The anti-HCV antibodies were investigated in all the individuals by immunoenzymatic assay. The reactive samples in duplicate were submitted to a polymerase chain reaction (PCR) to detect HCV-RNA. The positive tests were submitted for genotyping by the LIA method. One hundred and ten (10.9%; CI 95%: 9.1–13.0) HIV-positive individuals presented anti-HCV by EIA. The PCR was positive in 60 (6.0%; CI 95%: 4.6–7.6) individuals. The 1a genotype was the most frequent, followed by the 3a and 1b. The genotype 2 was found in only one individual. There were more male and intravenous drug users among HIV–HCV coinfected individuals when compared to only HIV-infected individuals. Multivariate analysis revealed an association between the HIV–HCV coinfection, regarding either EIA or PCR results, and the use of intravenous drugs, the presence of tattoos, and having received blood transfusions before 1994. There was no association of the coinfection with the variables related to sexual transmission. The relatively low prevalence of HCV infection in the HIV-positive population in that region may be a consequence of a small number of intravenous drug users in the sample, despite a strong association between HCV infection and use of intravenous drugs.
