The bony labyrinth of the inner ear houses the sensory end-organs responsible for balance (otolithic system in the utricle and saccule, and semicircular canal system) and hearing (cochlea). Study of the bony labyrinth has revealed considerable morphological diversity in the hominin lineage (semicircular canals and cochleae) and aided in reconstructing essential aspects of primate evolution, including positional behavior, audition, and phylogenic affinities. However, evidence of evolutionary change in the hominin otolithic system remains elusive.

The aim of this study was to perform molecular diagnosis of the main hemoparasites of dairy cows in the microregion of the central hinterland of Ceará.
Methods: For the molecular diagnosis of parasites, genomic material was extracted and polymerase chain reaction directed to the cdCatL-like gene for and SS rRNA of and was performed.
The present study identified professional training aspects in veterinary medicine at a federal public university in the Northeast of Brazil based on the graduates perception. The outcome of this study is anticipated to facilitate updating of pedagogical project execution of the courses in related areas to improve their curriculum. Hence, the course coordination started monitoring the graduates using an online questionnaire on the course webpage.

Here, we demonstrated that dietary γ-aminobutyric acid (GABA) with GABA-degradation inhibitory drugs could be an anti-obesity intervention possessing strong food intake-suppressive and weight-loss effects.
Methods: High-fat (HF)-diet-induced obese mice were divided into six groups receiving either the HF diet or the 2% GABA-HF diet with daily administration of PBS or the GABA-degradation inhibitory drugs, vigabatrin and ethanolamine-O-sulfate (EOS).

Background: Uncorrected myopia is a leading cause of blindness globally, with a rising prevalence in recent decades. Pathological myopia, often seen in individuals with increased axial length (AXL), can result in severe structural changes in the posterior pole, including myopic tractional maculopathy (MTM). MTM arises from tractional forces at the vitreoretinal interface, leading to progressive macular retinoschisis, macular holes, and retinal detachment (RD).

Methods: A case-control of incident cases of influenza A(H1N1) reported in the epidemiological information systems of the states of São Paulo, Paraná, Pará, Amazonas, and Rio Grande do Sul was conducted.
Results: 305 participants were included, 70 of them cases and 235 controls, distributed as follows: Amazonas, 9 cases/10 controls; Pará, 22 cases/77 controls, São Paulo, 19 cases/49 controls; Paraná, 10 cases/54 controls; Rio Grande do Sul, 10 cases/45 controls.
Background: Intracranial teratomas represent a rare subset of neoplasms characterized by tissues derived from multiple germ layers within the cranial cavity. These tumors, originating from primordial germ cells, exhibit diverse clinical presentations and histopathological features. While predominantly located along the midline axis, including the suprasellar cistern and pineal region, they can also manifest in less common areas such as ventricles and hypothalamic regions.

Immune thrombocytopenia (ITP) is most common in women during their reproductive years. When a low platelet count occurs for the first time during pregnancy, the differential diagnosis includes pregnancy-specific conditions. Although ITP is the most common cause of thrombocytopenia early in pregnancy, pregnancy-related thrombocytopenia develops mainly in late gestation.

To date, studies have extensively demonstrated effects of carnosine and anserine, the predominant muscular HCDs, on muscular functions and exercise performance. However, homocarnosine, the predominant brain HCD, is underexplored.

Methods: An ecological and cross-sectional study was conducted using data from the Mortality Information System. All deaths of patients residing in the state of São Paulo from 1996 to 2015 with at least one International Disease Code for SCD in any field of the death certificate were included.
Objective: To describe two cases of patients who had thrombotic microangiopathy (TMA) associated with sickle cell disease (SCD).
Case Description: Both patients started with a painful crisis and had acute chest syndrome during hospitalization. They showed significant worsening of hemolytic anemia, with very high levels of lactate dehydrogenase, thrombocytopenia, lowered level of consciousness, organ damage and the presence of schistocytes in peripheral blood.
Endophthalmitis is a severe form of purulent inflammation caused by the infection of the intraocular tissues or fluids. This infection infrequently occurs through endogenous routes, which are often correlated with major risk factors. Escherichia coli, a gram-negative rod, can cause endophthalmitis through hematogenous spread.

However, conduction disturbances leading to pacemaker implantation remain a common complication, increasing morbidity and mortality in these patients. Hence, measures to lower its incidence should be taken, and corticosteroid therapy could be effective by reducing inflammation caused by direct mechanical trauma to the conduction system.

We revisit the mandibular symphysis in juvenile specimens of Australopithecus africanus and Paranthropus robustus with two main contributions. First, we employ, for the first time, methods of computational anatomy to model complex symphyseal shape differences.

Imbalances of this neurotransmitter are associated with neurological diseases, such as Alzheimer's and Parkinson's disease, and psychological disorders, including anxiety, depression, and stress. Since GABA has long been believed to not cross the blood-brain barrier, the effects of circulating GABA on the brain are neglected.

However, since the beginning of the epidemic, the fight against the epidemic lacked foundations for managing cases to reduce the disease lethality. It was urgent to carry out studies that would indicate a model for predicting severe forms of influenza.
