The global increase in cancer cases and mortality has been associated with inflammatory processes, in which chemokines play crucial roles. These molecules, a subfamily of cytokines, are essential for the migration, adhesion, interaction, and positioning of immune cells throughout the body. Chemokines primarily originate in response to pathogenic stimuli and inflammatory cytokines.

Article Synopsis
  • This study systematically reviews methods for extracting and analyzing organic contaminants in crab urine, which are essential due to crabs' role as bioindicators of aquatic contamination.
  • Although harmful substances like PCBs and pesticides are known to affect ecosystems, most studies have focused mainly on PAHs, leaving a significant research gap.
  • The perception that collecting crab urine is difficult, along with insufficient methodologies in existing literature, highlights the need for more extensive research to improve ecological understanding and environmental monitoring efforts.

Article Synopsis
  • - The study presents a new method for separating extracellular vesicles (EVs) from plasma, focusing on their surface charges to improve the purity of EVs and reduce contamination by free plasma proteins.
  • - This charge-based fractionation technique was optimized through various analyses, including proteomics and electron microscopy, ensuring the effective isolation of EVs from healthy donors.
  • - The method was tested on clinical prostate cancer samples, showing promise for enhancing EV-based diagnostics and research, while also being user-friendly and accessible without specialized equipment.

6-Nitrodopamine (6-ND) is the predominant catecholamine released from isolated vascular tissues in both mammals and reptiles, with its release being significantly reduced by the NO synthesis inhibitor, N-nitro-L-arginine methyl ester (L-NAME). The vasorelaxation induced by 6-ND is unaffected by either L-NAME or the soluble guanylate cyclase (sGC) inhibitor, ODQ, indicating an alternative mechanism of action. The vasorelaxant effect appears to be mediated through selective antagonism of dopamine D receptors rather than traditional nitric oxide (NO)-mediated pathways.

Article Synopsis
  • Dapagliflozin is being studied for its potential to improve heart function in patients with chronic kidney disease, and this research seeks to see if it has similar benefits for those on dialysis.
  • The DARE-ESKD-2 trial involves adults on dialysis for over three months and randomly assigns them to receive either dapagliflozin or standard treatment for 24 weeks, measuring various heart function indicators.
  • With 80 patients enrolled, the trial aims to gather new insights on how SGLT2 inhibitors like dapagliflozin could be beneficial for patients with end-stage kidney disease undergoing dialysis.

Importance: Microplastic (MP) pollution is an emerging environmental and health concern. While MPs have been detected in various human tissues, their presence in the human brain has not been documented, raising important questions about potential neurotoxic effects and the mechanisms by which MPs might reach brain tissues.

Objective: To determine the presence of MPs in the human olfactory bulb and to analyze their characteristics such as size, morphology, color, and polymeric composition.

Endodontic microsurgery guided by navigation systems represents a precise and minimally invasive approach for retreatment of apical periodontitis following failed conventional endodontic therapy. Accurate localization and minimal access to the root apex are paramount for successful outcomes and preservation of anatomical structures. Workflow considerations, such as three-dimensional (3D) virtual planning and endodontic guidance represent new crucial aspects for addressing complex cases.

The Glycine Transporter Type 1 (GlyT1) significantly impacts central nervous system functions, influencing glycinergic and glutamatergic neurotransmission. Bitopertin, the first GlyT1 inhibitor in clinical trials, was developed for schizophrenia treatment but showed limited efficacy. Despite this, bitopertin's repositioning could advance treating various pathologies.

Background: The evidence in the literature suggests that some skeletal or dental malocclusions are involved with dental development, resulting in advanced or delayed dental age (DA). The purpose of this systematic review was to investigate the association between DA and different types of malocclusions.

Methods: The search was carried out on PubMed, Scopus, Web of Science, Virtual Health Library, and in the gray literature.

Background: Persistent symptoms and exercise intolerance have been reported after COVID-19, even months after the acute disease. Although, the long-term impact on exercise capacity and health-related quality of life (HRQoL) is still unclear.

Research Question: To assess the long-term functional capacity and HRQoL in patients hospitalized due to COVID-19.

Purpose: Sodium glucose co-transporter 2 inhibitors (SGLT2i) remarkably reduced the incidence of hospitalization for heart failure and cardiovascular death of conservatively managed chronic kidney disease. We hypothesized that adding SGLT2i to standard treatment would yield cardiovascular benefits also in end-stage kidney disease (ESKD) individuals on dialysis.

Methods: The DARE-ESKD-2 Trial (NCT05685394) is an ongoing, single-center, open-label, controlled trial aimed at assessing the cardiovascular effects of dapagliflozin in ESKD on dialysis.

Article Synopsis
  • The study examines how immune responses after intense exercise are affected by age and fitness levels in healthy men.
  • 32 physically active men were split into younger and older age groups, then further categorized by their fitness as measured by VO2max.
  • Results indicate that age moderately impacts certain immune markers, while fitness level does not significantly affect these responses.

Supplementation of dairy calves with essential oils in the liquid diet can reduce the incidence and severity of infectious diseases and promote better performance. Our objective was to evaluate an essential oil blend containing peppermint, eucalyptus, and menthol crystals and its effect on performance and health during the pre and postweaning period of dairy calves. At birth, 40 dairy calves (34 males and 6 females) were blocked according to sex and birth weight, randomly assigned to one of two treatments-commercial milk replacer diluted at 14% (MR) and the same liquid diet plus essential oil blend (MREO) at a dose of 4 mL per calf per day, divided into two meals during the first 28 days of life.

Toxoplasmosis causes serious harm to the fetus, as tachyzoite dissemination, during pregnancy in women developing the primo-infection. The microRNAs (miRNAs) are small non-coding RNAs, which have regulatory roles in cells by silencing messenger RNA. Circulating miRNA are promising biomarkers for diagnosis and prognosis of numerous diseases.

Introduction: The long-term consequences of COVID-19, especially pulmonary impairment, are frequent but not well understood. The knowledge about sequels or long COVID-19 are necessary, considering the high prevalence and need for specific public strategies.

Method: The study was conducted to evaluate symptoms (standardized questionnaire), pulmonary function (spirometry), and exercise capacity (6-minute-walk-test) at 30 (D30), 90 (D90), and 180 (D180) days after hospital discharge of patients surviving to severe COVID-19.

Article Synopsis
  • The COVID-19 pandemic has raised significant health concerns globally, making it essential to understand its clinical and epidemiological traits to inform control strategies.
  • A study in northeastern Brazil analyzed 115 severely ill COVID-19 patients in an ICU, revealing common symptoms such as dyspnea and cough, with many patients having multiple comorbidities, particularly hypertension.
  • Notably, having two or more comorbidities and lower platelet counts were associated with higher mortality, while cough emerged as a surprising protective factor against death.
