This study aimed to investigate whether the use of space and movements of Guiana dolphins were altered during the construction of a cable-stayed bridge at the mouth of the Cachoeira River estuary in Ilhéus, Brazil. We described and compared the visitation rate, use of space, and movements of the Guiana dolphins across two periods: before the construction began (2015-2016) and during the construction of the bridge (2017-2020). A theodolite and a total station were used to observe and record the trajectories of the dolphins.

However, the presence of preformed donor-specific antibodies (DSA), including those against HLA, can lead to antibody-mediated rejection and significantly impact transplant outcomes. The Flow Cytometry Crossmatch (FCXM) is a crucial tool in kidney transplantation, as it also enables the measurement of low levels of anti-HLA DSA antibodies.

There is a growing interest in Klotho proteins as potential diagnostic and prognostic biomarkers for multiple diseases. However, recent advances regarding their roles and potential applications in cancer remain disperse and require an integrated analysis.

This study aimed to evaluate the association between cesarean section and intelligence quotient (IQ) in adolescents from the Municipality of São Luís, Maranhão State, Brazil. This is a longitudinal study using data from the São Luís birth cohort, started in 1997. The approach occurred in the third phase of the cohort, in 2016, with adolescents aged 18 and 19 years.

This study aims to analyze the direct and indirect association between perceived discrimination and physical activity, mediated by common mental disorders in adolescents. This is a cross-sectional study with 2,484 adolescents (aged 18 and 19 years old) from a cohort in São Luís, Maranhão.

It is estimated that 65-80% of bacterial infections are biofilm related. Biofilms are complex bacterial communities composed of one or more species encased in an extracellular matrix made of proteins, carbohydrates and genetic material derived from the bacteria themselves as well as from the host.

Background: Melanized fungi are a distinct group of pathogens that cause infections like chromoblastomycosis and phaeohyphomycosis, especially in a state of immunosuppression including solid organ transplant recipients. Guidelines for the treatment of these infections are lacking, and there is no available standard recommendation.
Objective: To evaluate the therapeutic aspects of subcutaneous melanized fungal infections in kidney transplant recipients.
Objective: to analyze the process of deinstitutionalization resulting from a psychiatric hospital shut down, and know the fate of users after dehospitalization.
Method: a descriptive, qualitative study based on the critical-analytical perspective, which had as its setting the Hospital Colônia de Rio Bonito. Institutional documents and narratives of five managers who participated in the deinstitutionalization process were analyzed.
: To analyze the effects of body weight loss on bone mineral density (BMD) on hip (Hip BMD) and lumbar spine (Lumbar BMD) after six months of bariatric surgery. Bariatric surgery is an effective treatment for morbid obesity. Nonetheless, there are scant data on the effect of weight bearing on bone structure.

We tested whether these cetaceans could learn artificial individual sound cues played underwater and whether they would generalize this learning to airborne sounds. Dolphins are thought to perceive only underwater sounds and their training depends largely on visual signals.

These activities are not randomly distributed, with feeding being higher in early morning and late afternoon. Social activities and vocal behavior seem to be very important in dolphin daily activity.

The aim of the present study was to estimate the prevalence of dementia among elderly inpatients admitted to hospital medical wards and to identify its distribution across clinical and sociodemographic conditions.
Methods: From June 2011 to May 2012, a sample of elderly inpatients (≥60 years old) were screened for dementia with the Mini-Mental State Examination and the Bayer Activities of Daily Living Scale to identify cognitive and functional impairment (CFI).
Signature whistles have been widely studied in bottlenose dolphins (Tursiops truncatus). A recent study suggested the occurrence of signature whistles in Guiana dolphins (Sotalia guianensis) but could not identify the whistlers. The objective of this study is to describe the whistle characteristics in the population of S.

Conventional immunohistochemistry was employed to detect Fos-positive nuclei in the rd mouse retina and brain after monocular application of static and dynamic photic stimuli. Diffuse light induced Fos-positive nuclei in the inner nuclear and ganglion cell layers of the stimulated retina and in the contralateral pretectal olivary nucleus.
