(SCZ) is a severe mental disorder associated with persistent or recurrent psychosis, hallucinations, delusions, and thought disorders that affect approximately 26 million people worldwide, according to the World Health Organization. Several studies encompass machine learning (ML) and deep learning algorithms to automate the diagnosis of this mental disorder. Others study SCZ brain networks to get new insights into the dynamics of information processing in individuals suffering from the condition.

The aim of this study was to evaluate the antimicrobial efficacy of polyhexamethylene hydrochloride guanidine (PHMGH) compared to chlorhexidine digluconate (CLX) for use as an oral antiseptic during dental procedures in wild cats. This research is crucial due to limited information on the diversity of oral microorganisms in wild cats and the detrimental local and systemic effects of oral diseases, which highlights the importance of improving prevention and treatment strategies. Samples were collected from the oral cavities of four Puma concolor, one Panthera onca, and one Panthera leo, and the number of colony-forming units per milliliter (CFU/mL) was counted and semi-automatically identified.

Laboratory of Parasite-Host Interaction and Epidemiology (LaIPHE), Gonçalo Moniz Institute, Oswaldo Cruz Foundation (FIOCRUZ), Salvador 40296-710, Bahia, Brazil.

Skin ulcers of cutaneous leishmaniasis (CL) are characterized by a localized inflammatory response mediated by innate and adaptive immune cells, including dendritic cells (DC) and natural killer (NK) cells. Bidirectional interactions between DCs and NK cells contribute to tailor leishmaniasis outcome. Despite advances in the biology field in recent decades, the mechanisms involved in DC/NK-mediated control of sp.

There is a high perinatal mortality rate in dogs, estimated at 20%, and one of the leading causes of this rate is hypoglycaemia. Therefore, we aimed to evaluate the efficacy of a hypercaloric supplement containing vitamins and amino acids in newborn puppies presenting hypoglycaemia at birth. Ninety-nine pups were divided into four groups: normoglycaemic caesarean section (NORMOCS), hypoglycaemic caesarean section supplemented with the hypercaloric (SUPLCS), hypoglycaemic caesarean section supplemented with glucose (GLICCS) and eutocic delivery (EUT).

Article Synopsis
  • A new cyclic natural compound, formed from succinic acid and two alanine amino acid units, was isolated from honey extract and its structure was determined through various NMR techniques.
  • In cell culture studies, this compound reduced the number of tachyzoites (a parasitic stage) by 40-56% within 24 hours, and 25-50% over 72 hours, in a dose-dependent manner.
  • The compound showed no toxicity to glial cells at concentrations up to 25 µg/mL and was associated with increased nitric oxide levels, suggesting a potential impact on DNA synthesis and protein production in affected cells.

Background: Health impact assessment (HIA) is a widely used process that aims to identify the health impacts, positive or negative, of a policy or intervention that is not necessarily placed in the health sector. Most HIAs are done prospectively and aim to forecast expected health impacts under assumed policy implementation. HIAs may quantitatively and/ or qualitatively assess health impacts, with this study focusing on the former.

Background: Cesarean section (CS) rates are increasing worldwide and are associated with negative maternal and child health outcomes when performed without medical indication. However, there is still limited knowledge about the association between high CS rates and early-term births. This study explored the association between CSs and early-term births according to the Robson classification.

Background: Social determinants of health (SDH) include factors such as income, education, and race, that could significantly affect the human immunodeficiency virus and acquired immunodeficiency syndrome (HIV/AIDS). Studies on the effects of SDH on HIV/AIDS are limited, and do not yet provide a systematic understanding of how the various SDH act on important indicators of HIV/AIDS progression. We aimed to evaluate the effects of SDH on AIDS morbidity and mortality.

Voriconazole is a triazole antifungal used empirically for the treatment of complicated meningitis associated with . Biopsy studies show that the drug exhibits adequate brain penetration although levels of cerebral spinal fluid (CSF) are highly variable. Considering that CSF is one of the main surrogates for CNS exposure, the present work proposed the building of a population pharmacokinetic modeling (popPK) model able to describing the exposure achieved by voriconazole in the plasma, interstitial cerebral fluid and CSF of healthy and infected rats.

To review the effects of photobiomodulation therapy (PBMT) on pain intensity and disability in people with plantar fasciitis (PF) when compared with control conditions, other interventions, and adjunct therapies. Systematic searches were conducted in five database randomized controlled trials (RCT). We only included randomized controlled trials (RCTs) in adults with PF that compared PBMT to placebo, as well as RCTs that compared PBMT to other interventions; and as an adjunct to other therapies.

  • - This study investigates how methylmercury (MeHg) exposure impacts tooth enamel in rats, particularly during critical periods of prenatal and postnatal development when enamel forms.
  • - Researchers gave female rats a specific dose of MeHg during pregnancy and lactation, then analyzed their offspring's enamel using advanced techniques like infrared spectroscopy and electron microscopy.
  • - Results showed that MeHg exposure led to significant alterations in the enamel's inorganic and organic composition, affecting its structure and strength, highlighting the potential risks of MeHg exposure on dental health in developing organisms.

Background And Objective: Some studies on maintenance hemodialysis (MHD) patients report a longer survival, albeit with poorer health-related quality of life (HRQoL), and more depression symptoms in women than in men. Whether these gender differences vary with age is uncertain. We tested the associations of gender with mortality, depression symptoms, and HRQoL in MHD patients of different age groups.

Alzheimer's Disease (AD) is a neurodegenerative condition characterized by progressive memory loss and other affected cognitive functions. Pharmacological therapy of AD relies on inhibitors of the enzymes acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), offering only a palliative effect and being incapable of stopping or reversing the neurodegenerative process. However, recent studies have shown that inhibiting the enzyme β-secretase 1 (BACE-1) may be able to stop neurodegeneration, making it a promising target.

Cancer cells produce abnormal levels of reactive oxygen species (ROS) that contribute to promote their malignant phenotype. In this framework, we hypothesized that the change in ROS concentration above threshold could impair key events of prostate cancer cells (PC-3) progression. Our results demonstrated that Pollonein-LAAO, a new L-amino acid oxidase obtained from Bothrops moojeni venom, was cytotoxic to PC-3 cells in two-dimensional and in tumor spheroid assays.
