The purpose of this work was to study further two Bradyrhizobium japonicum strains with high nitrogen-fixing capacity that were identified within a collection of approximately 200 isolates from the soils of Argentina. Nodulation and nitrogen-fixing capacity and the level of expression of regulatory as well as structural genes of nitrogen fixation and the 1-aminocyclopropane-1-carboxylate (ACC) deaminase gene of the isolates were compared with that of E109-inoculated plants. Both isolates of B. japonicum, 163 and 366, were highly efficient to fix nitrogen compared to commercial strain E109...

Two cryptic species of haploporid digeneans belonging in Saccocoelioides are described from Costa Rica; one from a poeciliid fish Poecilia gillii and the other from a characid fish, Astyanx aeneus. Traditional morphological features are examined and found to be largely inefficient for differentiate among new species and 20 New World congeners. Comparison of ribosomal DNA sequences among the 2 new species, 2 North American, 4 Middle American, and 3 South American species of Saccocoelioides, including the type-species Saccocoelioides nanii from Argentina and Saccocoelioides sogandaresi from Texas, is effective for differentiating among these species...

Argentina passed a law for humanized birth in 2004 and another law against obstetric violence in 2009, both of which stipulate the rights of women to achieve respectful maternity care. Clinicians and women might still be unaware of these laws, however. In this article, we discuss the case of a fourth-year medical student who, while visiting Argentina from the United States for his obstetric rotation, witnesses an act of obstetric violence. We show that the student's situation can be understood as one of moral distress and argue that, in this specific instance, it would be appropriate for the student to intervene by providing supportive care to the patient...

AIMS: While there are effective treatments for psychiatric disorders, many individuals with such disorders do not receive treatment and those that do often take years to get into treatment. Information regarding treatment contact failure and delay in Argentina is needed to guide public health policy and planning. Therefore, this study aimed to provide data on prompt treatment contact, lifetime treatment contact, median duration of treatment delays and socio-demographic predictors of treatment contact after the first onset of a mental disorder...

The southern distribution of the Broad-snouted Caiman (Caiman latirostris Daudin 1802) in Argentina occurs in Santa Fe Province, where its population has been under management by "Proyecto Yacaré" since 1990. From 1997 to 2016, we captured 77 nesting female Broad-snouted Caimans in Santa Fe Province. Our results suggest that previously defined size classes for Broad-snouted Caiman do not adequately describe the reproductively mature female segment of the population. Here we propose to change size ranges for general size classes for Broad-snouted Caiman...

Swarm-founding wasps are endemic and common representatives of neotropical fauna and compose an interesting social tribe of vespids, presenting both complex social characteristics and uncommon traits for a eusocial group, such as the absence of castes with distinct morphology. The paper wasp Protonectarina sylveirae (Saussure) presents a broad distribution from Brazil, Argentina and Paraguay, occurring widespread in the Atlantic rainforest and arboreal Caatinga, being absent in the Amazon region. Given the peculiar distribution among swarm-founding wasps, an integrative approach to reconstruct the evolutionary history of P...

BACKGROUND: Historically, neural tube defects (NTDs) have predominated in female infants but the reasons remain unclear. In South America, the pre- folic acid fortification (FAF) rates of NTDs were around 18/10,000 births for females and 12/10,000 births for males, with an estimated sex ratio (male/female) of 0.67. During the post- FAF period, unpublished routine reports have indicated changes in the sex ratio for these defects while some descriptive reports are controversial. To date and to our knowledge, however, no studies specifically focusing on these changes to test this hypothesis directly have been undertaken...

Chemical bioprospecting is an important tool for generating knowledge regarding local human-threatened floras and for conservation management. For Baccharis L. (Asteraceae), several volatile components have been reported for Brazil, Argentina, Bolivia, and Chile as a result of bioprospection, but not for Uruguayan flora, which is composed of more than 50 native species. In this work, through collection of aerial parts of different species and volatile simultaneous-distillation extraction and gas chromatography-mass spectrometry analyses, 12 native species of Baccharis were studied (B...

Pregnancy complications and obstetric outcomes were compared in 80 Chilean (PPCOSCh ) and 70 Argentinian (PPCOSAr ) pregnant women. Reference groups of Chilean and Argentinian normal pregnant women from the same antenatal care units were also compared. PPCOSCh showed a higher prevalence of gestational diabetes mellitus (GDM) (OR, 2.28, 95% CI: 1.08-4.77, p = .030) and a lower prevalence of pregnancy-induced hypertension (PIH) (OR, 0.20, 95% CI: 0.07-0.54, p = .001) compared to PPCOSAr . In the normal pregnant groups, the prevalence of PIH was lower in Chilean women compared to Argentinian women (OR, 0...

The environmental, socioeconomic and cultural significance of glaciers has motivated several countries to regulate activities on glaciers and glacierized surroundings. However, laws written to specifically protect mountain glaciers have only recently been considered within national political agendas. Glacier Protection Laws (GPLs) originate in countries where mining has damaged glaciers and have been adopted with the aim of protecting the cryosphere from harmful activities. Here, we analyze GPLs in Argentina (approved) and Chile (under discussion) to identify potential environmental conflicts arising from law restrictions and omissions...

STUDY QUESTION: Is ceramide-1-phosphate (C1P) an ovarian protective agent during alkylating chemotherapy? SUMMARY ANSWER: Local administration of C1P drastically reduces ovarian damage induced by cyclophosphamide (Cy) via protection of follicular reserve, restoration of hormone levels, inhibition of apoptosis and improvement of stromal vasculature, while protecting fertility, oocyte quality and uterine morphology. WHAT IS KNOWN ALREADY: Cancer-directed therapies cause accelerated loss of ovarian reserve and lead to premature ovarian failure (POF)...

A new species of Didymium (Myxomycetes), D. azorellae, isolated from plant debris in a moist chamber, collected during studies of cold arid areas of Argentina and Peru, is described. It can be distinguished by its small size, the tightly packed layer of lime crystals on the peridium, the very scant, or absent, capillitium, and the unique spore ornamentation, especially by scanning electron microscopy. The species developed on dead leaves of cushion plants growing in the extremely harsh environments of the central Andean puna at almost 5000 m elevation and the Andino-Patagonian steppe...

BACKGROUND: Aspergillus arachidicola is an aflatoxigenic fungal species, first isolated from the leaves of a wild peanut species native to Argentina. It has since been reported in maize, Brazil nut and human sputum samples. This aflatoxigenic species is capable of secreting both B and G aflatoxins, similar to A. parasiticus and A. nomius. It has other characteristics that may result in its misidentification as one of several other section Flavi species. This study offers a preliminary analysis of the A...

INTRODUCTION: In Argentina, like in the rest of the world, deinstitutionalization policies have been implemented. In our country, the shortage of epidemiologic data regarding admissions in mental health is a limitation for the discussion about how this changes should be implemented and its effect. OBJECTIVES: Epidemiologic data of inpatients of the Mental Health Unit of the Teodoro Álvarez General Hospital between June 2012 and May 2013 has been analyzed in order to elaborate a comparative analysis with a previous study that took place in the same unit on the years 2004-2005...

The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia...

Although depression is a treatable cause of suffering, disability and death, its identifcation and treatment continue to be a challenge in clinical practice and a severe problem for global public health. The main objective of this study was to investigate the frequency with which mental health professionals use scales to assess depressive patients in Argentina and to determine the reasons that constrain such practice. Between July and September 2012 a national survey was conducted by e-mail. Professionals registered in the database of the Argentine Association of Psychiatrists were invited to participate in the survey...
