SEEDLINGS PRODUCTION OF UMBUZEIRO ( Spondias tuberosa Arruda C\ue2mara) IN DIFFERENT SUBSTRATES AND SIZE OF BAGS
A esp\ue9cie Spondias tuberosa Arr. Cam. (umbuzeiro) destaca-se
como uma das esp\ue9cies arb\uf3reas de maior potencial do
semi\ue1rido brasileiro. Apesar de sua relevante import\ue2ncia
socioecon\uf4mica e ambiental, h\ue1 falta de estudos voltados para
o estabelecimento de um modelo de produ\ue7\ue3o de mudas da
esp\ue9cie. O objetivo desse trabalho foi avaliar a
produ\ue7\ue3o de mudas de Spondias tuberosa utilizando diferentes
substratos e tamanho de recipientes. O experimento foi conduzido no
viveiro do Laborat\uf3rio de Ecologia Vegetal (LEV) do Centro de
Ci\ueancias Agr\ue1rias (CCA) da Universidade Federal da
Para\uedba (UFPB), Areia - PB. O delineamento experimental usado foi
em blocos casualizados em esquema fatorial 2 x 7 e parcelas
subdivididas, sendo que os recipientes representaram as parcelas e os
substratos as subparcelas. Foram utilizados substratos formulados a
partir da mistura de terra de subsolo (37,5-100%), areia lavada (12,5-
25%) e esterco bovino curtido (10-50%). Os recipientes utilizados foram
sacos de polietileno preto com volumes de 1900 cm3 (15 x 27 cm) e 5000
cm3 (25 x 26 cm). Para a obten\ue7\ue3o das pl\ue2ntulas,
sementes de Spondias tuberosa foram semeadas em sementeira de alvenaria
at\ue9 a repicagem (90 dias ap\uf3s o semeio). Aos 78 dias,
ap\uf3s a repicagem, as mudas foram avaliadas quanto \ue0 altura,
di\ue2metro do colo, rela\ue7\ue3o altura/ di\ue2metro do colo,
di\ue2metro do xilop\uf3dio, comprimento de raiz, massa seca da
parte a\ue9rea e raiz. Os dados obtidos foram submetidos \ue0
an\ue1lise de vari\ue2ncia e ao teste F, sendo as m\ue9dias
comparadas pelo teste de Tukey ao n\uedvel de 5% de probabilidade,
utilizando o software SISVAR\uae. Os substratos com esterco bovino
curtido proporcionaram os maiores valores em altura e comprimento de
raiz. Para a produ\ue7\ue3o de mudas de Spondias tuberosa, \ue9
recomendado o substrato contendo terra de subsolo (45%) + Areia (15%) +
Esterco bovino (40%).The species Spondias tuberosa Arr. Cam. (umbuzeiro) stands out as one
of the tree species with the greatest potential of the Brazilian
semiarid. Even though it\u2019s significant socioeconomic and
environmental importance, there is a lack of studies aimed at
establishing a seedlings production model of this kind of plant. The
purpose of this study was to evaluate the production of seedlings
Spondias tuberosa using different substrates and size of bags. The
experiment was conducted in the nursery of the Plant Ecology Laboratory
(LEV) from the Agrarian Sciences Center (CCA) of the Federal University
of Paraiba (UFPB), Areia/ PB. The experimental design was a randomized
block in factorial 2 x 7 and subdivided blocks containersplots and
subplots substrates. It were used substrates formulated from the
starting mixture of subsoil land (37.5-100%), sand (12.5-25%) and
tanned cattle manure (10-50%). The containers used were black
polyethylene bags with a volume of 1900 cm3 (15 x 27 cm) and 5000 cm3
(25 x 26 cm). To obtain seedlings of Spondias tuberosa seeds were sown
in seed masonry until the transplant (90 days after sowing). At 78 days
after transplanting the seedlings were evaluated for height, root
collar diameter, relationship shoot/root collar diameter, xylopodium
diameter, root length, dry weigh of shoot and root. The datas were
subjected to analysis of variance and F test, measured and compared by
Tukey test at 5% probability, using the software SISVAR\uae. The
substrates with cattle manure provided higher values for height and
root length. For the seedlings production of Spondias tuberosa, is
recommended substrate subsoil land (45%) + sand (15%) + cattle manure
(40%)
SALT STRESS ON THE PHYSIOLOGICAL QUALITY OF Cryptostegia madagascariensis Bojer ex Decne. SEEDS
A esp\ue9cie Cryptostegia madagascariensis Bojer ex Decne. foi
introduzida no Brasil com fins ornamentais, mas, atualmente, \ue9 uma
invasora do bioma Caatinga. Apesar de sua elevada capacidade de
ocupa\ue7\ue3o de \ue1reas alteradas do referido bioma, h\ue1
car\ueancia de informa\ue7\uf5es sobre esta esp\ue9cie,
particularmente em rela\ue7\ue3o \ue0 capacidade de suas sementes
germinarem em condi\ue7\uf5es adversas. O objetivo deste trabalho
foi avaliar a germina\ue7\ue3o de sementes e o crescimento inicial
de pl\ue2ntulas de Cryptostegia madagascariensis em fun\ue7\ue3o
da salinidade em diferentes temperaturas. O experimento foi realizado
seguindo um delineamento inteiramente casualizado, com os tratamentos
distribu\ueddos em esquema fatorial 6 x 3, sendo seis n\uedveis de
salinidade promovidos pelo cloreto de s\uf3dio (NaCl): 0,0
(controle); 2,0; 4,0; 6,0; 8,0 e 10,0 dS m-1; e tr\ueas temperaturas:
25 e 30\ub0C constantes e alternada de 20-35\ub0C. A qualidade
fisiol\uf3gica das sementes foi avaliada pelas seguintes
vari\ue1veis: germina\ue7\ue3o, primeira contagem e \uedndice
de velocidade de germina\ue7\ue3o, comprimento e massa seca de
ra\uedzes e do hipoc\uf3tilo. Os resultados obtidos indicam que
h\ue1 elevada probabilidade de germina\ue7\ue3o de sementes de
Cryptostegia madagascariensis submetidas a estresse salino em
temperatura constante de 30\ub0C e alternada de 20-35\ub0C, o que
potencializa o seu car\ue1ter invasor.The Cryptostegia madagascariensis Bojer ex Decne. species was
introduced in Brazil with ornamental purposes, but currently, it is
invasive in the Caatinga biome. Despite its high level of occupancy of
altered areas of Caatinga, there is lack of information about this
species, particularly in relation to the capacity of its seeds to
germinate in adverse conditions. The objective of this study was to
evaluate seed germination and the initial seedling growth of
Cryptostegia madagascariensis in function of salinity at different
temperatures. The experiment was conducted following a completely
randomized design, with treatments arranged in a 6 x 3 factorial design
with six salinity levels promoted by sodium chloride (NaCl): 0.0
(control); 2.0; 4.0; 6.0; 8.0 and 10.0 dS m-1 and three temperatures:
25 and 30\ub0C constant and alternating 20-35\ub0C. The
physiological quality of seeds was evaluated using the following
variables: germination, first count and the speed of germination index,
length and dry weight of roots and hypocotyl. The results indicate that
there is high probability of seed germination of Cryptostegia
madagascariensis subjected to salt stress at constant temperature of
30\ub0C and alternating 20-35\ub0C, which enhances its invasive
character
A tetravalent dengue nanoparticle stimulates antibody production in mice
<p>Abstract</p> <p>Background</p> <p>Dengue is a major public health problem worldwide, especially in the tropical and subtropical regions of the world. Infection with a single <it>Dengue virus </it>(DENV) serotype causes a mild, self-limiting febrile illness called dengue fever. However, a subset of patients experiencing secondary infection with a different serotype progresses to the severe form of the disease, dengue hemorrhagic fever/dengue shock syndrome. Currently, there are no licensed vaccines or antiviral drugs to prevent or treat dengue infections. Biodegradable nanoparticles coated with proteins represent a promising method for in vivo delivery of vaccines.</p> <p>Findings</p> <p>Here, we used a murine model to evaluate the IgG production after administration of inactivated DENV corresponding to all four serotypes adsorbed to bovine serum albumin nanoparticles. This formulation induced a production of anti-DENV IgG antibodies (p < 0.001). However, plaque reduction neutralization assays with the four DENV serotypes revealed that these antibodies have no neutralizing activity in the dilutions tested.</p> <p>Conclusions</p> <p>Our results show that while the nanoparticle system induces humoral responses against DENV, further investigation with different DENV antigens will be required to improve immunogenicity, epitope specicity, and functional activity to make this platform a viable option for DENV vaccines.</p

Conservation of marizeiro Geoffroea spinosa Jacq. seeds using different packagings and environments
O marizeiro ( Geoffroea spinosa Jacq.) \ue9 uma esp\ue9cie
florestal importante, sobretudo por ser adaptada \ue0s
condi\ue7\uf5es de matas ciliares do semi-\ue1rido e ecossistemas
associados, ocorrendo em vastas \ue1reas do Nordeste brasileiro e no
vale do rio S\ue3o Francisco, sempre restrita a ambientes
sazonalmente inundados. Este trabalho teve como objetivos avaliar o
efeito de diferentes tipos de embalagens e do per\uedodo de
armazenamento sobre o processo germinativo e o vigor de sementes de
Geoffroea spinosa Jacq. acondicionadas tamb\ue9m em diferentes
ambientes. O experimento foi instalado no Laborat\uf3rio de Ecologia
Vegetal do CCA/UFPB, seguindo um delineamento inteiramente casualizado.
As sementes foram distribu\ueddas em dois ambientes
(condi\ue7\uf5es naturais, no laborat\uf3rio e c\ue2mara fria),
acondicionadas em dois tipos de embalagens (sacos de papel e sacos
pl\ue1sticos) durante cinco per\uedodos de armazenamento: 0, 15,
30, 60 e 90 dias. Foram avaliados o teor de \ue1gua, o \uedndice de
velocidade de emerg\ueancia, a massa seca e o comprimento de
pl\ue2ntulas. Os dados foram submetidos \ue0 an\ue1lise de
regress\ue3o polinomial. Na embalagem pl\ue1stica e no ambiente de
c\ue2mara fria, houve menor redu\ue7\ue3o da viabilidade e do
vigor ao longo do armazenamento. As sementes acondicionadas em sacos de
papel e armazenadas em ambiente de laborat\uf3rio perderam
rapidamente a viabilidade e o vigor a partir dos 30 dias de
armazenamento.Geoffroea spinosa Jacq., commonly known as marizeiro in Brazil, is an
important tree species, mainly because it is adapted to riparian forest
conditions in semi-arid and associated ecosystems. The species occur in
large areas of northeastern Brazil and in the S\ue3o Francisco river
valley, always restricted to seasonally flooded environments. This
study aimed to evaluate the effect of different types of packaging and
storage periods, as well the influence of environments on the process
of seed germination and vigor of Geoffroea spinosa. The experiment was
carried out at the Laboratory of Plant Ecology - CCA/UFPB, following a
completely randomized design. The seeds were distributed among two
environments (natural conditions in the laboratory and cold room),
packed in two types of packaging (paper bags and plastic bags) for five
periods of storage: 0; 15; 30; 60 and 90 days. Water content, the
emergence velocity index, dry weight and length of seedlings were
evaluated. The data were submitted to a polynomial regression analysis.
In plastic packaging and the environment of the cold room there was
less reduction of viability and vigor during storage. Seeds packed in
paper bags and stored in a laboratory rapidly lost viability and vigor,
after 30 days of storage
Predictor variables and screening protocol for depressive and anxiety disorders in cancer outpatients
Background
Cancer patients are at increased risk of persistent depressive and anxiety symptoms and disorders compared to the general population. However, these issues are not always identified, which may worsen the prognosis and increase morbidity and mortality. Therefore, the objectives of this study are to identify predictor variables (demographic and clinical) for the development of mood and anxiety disorders in cancer outpatients and to propose a probabilistic screening protocol considering these variables and certain standardized screening instruments.
Methods
A total of 1,385 adults, of both genders, receiving outpatient cancer care were evaluated using a questionnaire and screening instruments. Thereafter, 400 of these subjects responded to the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID-IV) by telephone to confirm or rule out the presence of a Current Major Depressive Episode (CMDE) or Anxiety Disorder (AD).
Results
Of the patients surveyed, 64% met the criteria for CMDE and 41% for AD. Female gender was found to be a risk factor for both disorders, and the presence of previous psychiatric history and marital status (divorced and widowed) were risk factors for anxiety disorders. When scoring above the recommended cutoff score, the screening instruments also indicated a risk of the studied disorders. Based on these findings, a screening protocol and nomograms were created for the quantification, combination and probabilistic estimate of risk, with accuracy indicators >0.68.
Conclusion
The prevalence rates for the disorders under study are extremely high in cancer patients. The use of the proposed protocol and nomogram can facilitate rapid and wide screening, thus refining triage and supporting the establishment of criteria for referral to mental health professionals, so that patients can be properly diagnosed and treated.info:eu-repo/semantics/publishedVersio
