Article Synopsis
  • Problematic gaming (PG) is a mental health issue linked to negative outcomes, with a focus on its potential connection to psychotic experiences (PE), which is not well-researched.
  • A study conducted with a large group of Brazilian adolescents (ages 13-21) revealed that those with PG reported higher levels of PE compared to those without PG, even after controlling for other factors like psychiatric disorders.
  • The findings suggest that there may be shared underlying mechanisms between PG and PE, indicating a need for further research in this area.

Little is known about the biology of pygmy sperm whales, Kogia breviceps (De Blainville, 1838), being that most anatomical descriptions for the species derive from necropsy after stranding or from osteological material preserved in museums. This species is rarely seen despite its wide distribution, and its reproductive behaviour is still being investigated. The eventual occurrence of pregnant female strandings and the collection and description of foetuses can give clues about the organisms' mostly unknown early development.

Article Synopsis
  • Fusarioid fungi, like Neocosmospora solani and Fusarium oxysporum, are becoming important human pathogens causing a range of infections, which makes accurate identification and preservation in labs crucial.
  • This study introduced a new medium called milk-honey and malt agar (MHM) that outperformed traditional media (like Sabouraud dextrose agar) in cultivating and preserving fusarioid fungi isolates, significantly enhancing conidia production and viability.
  • MHM showed distinct growth patterns for different fusarioid species, highlighting its potential as an effective tool for clinical mycology laboratories, especially in resource-limited environments.

Land use change, especially mining activities, contributes to anthropic CO emissions, leading to decreased carbon (C) storage and loss of biodiversity. Artisanal gold mining associated with the use of mercury (Hg) for amalgamation may change soil organic matter (SOM) contents, and the release of Hg into the environment generates serious environmental problems. Changes in soil biogeochemistry due to C loss and seasonal climate fluctuations affect Hg dynamics and can either increase or decrease its availability.

In mammals, the central circadian oscillator is located in the suprachiasmatic nucleus (SCN). Hypothalamus-pituitary-thyroid axis components exhibit circadian oscillation, regulated by both central clock innervation and intrinsic circadian clocks in the anterior pituitary and thyroid glands. Thyroid disorders alter the rhythmicity of peripheral clocks in a tissue-dependent response; however, whether these effects are influenced by alterations in the master clock remains unknown.

Objective: To analyze whether there are differences in the cepstral measures obtained in different speech tasks, depending on the presence and degree of vocal deviation, and to analyze if there is a correlation between the cepstral measures obtained from different speech tasks and the general degree of vocal deviation.

Method: Analysis of 258 vocal samples of the sustained vowel [a] and connected speech (counting numbers) from a database, including 160 dysphonic and 98 nondysphonic voices. The counting number samples were edited in three different durations: counting from 1 to 10, from 1 to 11, and from 1 to 20.

The muscle metaboreflex effect on pulmonary ventilation (V̇) regulation is more apparent during rhythmic exercise than rest, possibly because this reflex interacts with other mechanisms regulating V̇ during voluntary contractions, such as central command. Therefore, we tested whether one part of central command, the descending component of motor execution (i.e.

Arthritogenic alphaviruses pose a significant public health concern due to their ability to cause joint inflammation, with emerging evidence of potential neurological consequences. In this review, we examine the immunopathology and immune evasion strategies employed by these viruses, highlighting their complex mechanisms of pathogenesis and neurological implications. We delve into how these viruses manipulate host immune responses, modulate inflammatory pathways, and potentially establish persistent infections.

Autophagy initiation is regulated by the ULK1 kinase complex. To gain insights into functions of the holo-complex, we generated a deep interactome by combining affinity purification- and proximity labeling-mass spectrometry of all four complex members: ULK1, ATG13, ATG101, and RB1CC1/FIP200. Under starvation conditions, the ULK1 complex interacts with several protein and lipid kinases and phosphatases, implying the formation of a signalosome.

The severity and invasiveness of clinical outcomes from organic responses to trauma are influenced by individual, surgical, and anesthetic factors. A stress response elicits neuroendocrine and immune reactions that may lead to multi-organ dysfunction. The degree of neuroinflammatory reflex activation from trauma can increase pro-inflammatory cytokine production, leading to endothelial dysfunction, glycocalyx damage, neutrophil activation, and multisystem tissue destruction.

We present a computational model of networked neurons developed to study the effect of temperature on neuronal synchronization in the brain in association with seizures. The network consists of a set of chaotic bursting neurons surrounding a core tonic neuron in a square lattice with periodic boundary conditions. Each neuron is reciprocally coupled to its four nearest neighbors via temperature dependent gap junctions.

This case series reports eight eyes with keratoconus treated with laser implantation of one or two segments of progressive thickness corneal intrastromal ring (PT-ICRS). In this case series, it was evident that the insertion of PT-ICRS induces more pronounced corneal flattening at the thickest point, causing a reduction in distortion (coma) and lower astigmatism, resulting in a remarkable improvement in vision. Compared to the implementation of traditional intrastromal rings, the PT-ICRS variant showed superior results despite the small sample size.

Knowledge of performance in activities of daily living and quality of life is important for management decisions and research endpoints. The use of harmonized scales is essential for objective assessment of both caregivers and patients with dementia with Lewy bodies. Functionality and quality of life are more impaired in dementia with Lewy bodies than in Alzheimer's disease, mostly due to higher prevalence of behavioral symptoms and motor manifestations in dementia with Lewy bodies.

Article Synopsis
  • The study aimed to compare the refractive outcomes of mechanical PRK (mPRK) and transepithelial PRK (tPRK) using the WaveLight Allegretto EX500 laser system in patients with astigmatism and myopia.
  • Conducted at the Federal University of Sao Paulo, Brazil, the prospective randomized study involved 151 eyes from 73 patients, ensuring minimal differences in pre-surgery refraction.
  • Results indicated that six months post-surgery, mPRK had better uncorrected distance visual acuity (UDVA) and spherical equivalent (SE) compared to tPRK, though both procedures showed similar safety profiles.
