The endocannabinoid system (ECS), regulating such processes as energy homeostasis, inflammation, and muscle function, centers around cannabinoid receptors, including CB1. These receptors are mainly located in the central nervous system and skeletal muscles. Hyperactivity of CB1 receptors is linked to metabolic disorders and chronic inflammation, highlighting their potential as therapeutic targets for muscle hypertrophy and metabolic health.

Resveratrol, a natural polyphenol, has shown promising neuroprotective effects in several in vivo and in vitro experimental models. However, the mechanisms by which resveratrol mediates these effects are not fully understood. Glutamate is the major excitatory neurotransmitter in the brain; however, excessive extracellular glutamate levels can affect neural activity in several neurological diseases.

Background: The host immune response plays a major role in the pathogenesis of periodontitis. A bibliometric study can be crucial to understanding the different processes involved in this area; however, to our knowledge, it has not been published until now. Therefore, a bibliometric analysis was conducted to assess research hotspots and global trends in scientific articles about the immune response in periodontitis published between 1952 and 2023.

Mental health (MH) comorbidities are prevalent among people with epilepsy (PWE), but many experience challenges accessing care. To address this, suggestions have been made to integrate MH care into epilepsy care settings, yet the current approaches, benefits, and implementation determinants to MH care integration are unclear. This review aims to synthesize existing integrated MH care models for PWE to inform the development and planning of future initiatives.

To clarify the effects of kefir in critical periods of development in adult diseases, we study the effects of kefir intake during early life on gut microbiota and prevention of colorectal carcinogenesis in adulthood. Lactating Wistar rats were divided into three groups: control (C), kefir lactation (KL), and kefir puberty (KP) groups. The C and KP groups received 1 mL of water/day; KL dams received kefir milk daily (10 CFU/mL) during lactation.

Introduction: Intrauterine devices (IUDs) are highly effective contraceptives. Despite their effectiveness, pregnancies can occur during IUD use, and the management of such cases, particularly when the pregnancy is desired, remains controversial.
Material And Methods: We conducted a systematic review and meta-analysis to evaluate outcomes in women who unintentionally conceived while using IUDs and chose to continue their pregnancies.

While established guidelines exist for chirality in tetrahedral molecules, there is a notable absence of clear rules for recognizing metal-centered chirality in higher-coordination complexes. We develop decision trees to assess the likelihood of chirality-at-metal in coordination complexes with coordination numbers 4-9 with mono and bidentate ligands. Using binary decision rules based on shape, ligand type, and quantity, the trees classify complexes as chiral or achiral.

The World Health Organization recommended the global elimination of industrial trans fats by 2023, leading to a decrease in their use in packaged foods. Nevertheless, a gap remains in the scientific literature regarding the ingredients adopted as substitutes by the food industry. This study aimed to map evidence on substitutes for industrial trans fats in packaged foods, discussing their possible designation in the ingredients lists.

Although breast, cervical, endometrial, and ovarian cancers account for more than 43% of new cases in 2023 in Brazilian women, no national studies were found on the incidence, risk factors, and prevention of breast and gynecological neoplasms in lesbian women, causing the health needs of non-heterosexual women to go unnoticed by professionals. This study aims to identify and analyze the search for healthcare related to the prevention of breast/gynecological cancer among Brazilian lesbian cisgender women who have not had the disease. Seven lesbian women participated in this qualitative study.

Co-cropping of hyperaccumulators is still poorly understood, while associations between hyperaccumulators and other plant species may promote beneficial plant interactions and lead to increased metal phytoextraction from contaminated soils. The aim of this study was to evaluate the phytoextraction potential of the Ni-hyperaccumulator in different co-cropping combinations with and . Plants were grown in ultramafic soil in a growth chamber for 45 days and Al, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn concentrations in roots and leaves were analyzed.

In critically ill patients, the occurrence of multidrug-resistant infection is a significant concern, given its ability to acquire multidrug-resistant, form biofilms and secrete toxic effectors. In Brazil, limited data are available regarding the prevalence of dissemination, and the impact of the type III secretion system (T3SS) on toxin production and biofilm formation in clinical isolates of . This study investigates the dissemination of virulent harbouring the and genes, the presence of T3SS genes and their biofilm-forming capability.

Background: Recommending comprehensive personalized photoprotection requires an accurate assessment of the patient's skin, including phototype, lifestyle, exposure conditions, environmental factors, and concomitant cutaneous conditions as well as deep knowledge of the available options: sunscreen ingredients (type of filters, spectrum coverage, sun protection factor, enhanced active ingredients), oral photoprotection, and other methods of sun protection and avoidance.
Objectives: To establish consensus-based recommendations endorsed by an international panel of experts for personalized medical photoprotection recommendations that are applicable globally.
Methods: A two-round Delphi study was designed to determine the degree of agreement and relevance of aspects related to personalized medical photoprotection.

The aim of this study was to assess the gamma-aminobutyric acid (GABA) production in plant-based fermented beverages with kefir cultures (milk and water kefir). Water-soluble extracts of peanut and Brazil nut were evaluated as non-dairy substrates for the development of new bioactive beverages. A total of 12 formulations were developed and evaluated for their chemical composition, physical chemical characterization, and microbiological counts (aerobic mesophilic bacteria, lactobacilli, lactococci and yeasts).

Although emerging data have revealed the critical role of memory CD8 T cells in preventing and controlling SARS-CoV-2 infection, virus-specific CD8 T-cell responses against SARS-CoV-2 and its memory and innate-like subsets in unvaccinated COVID-19 patients with various disease manifestations in an HLA-restricted fashion remain to be understood. Here, we show the strong association of protective cellular immunity with mild COVID-19 and unique cell types against SARS-CoV-2 virus in an HLA-A2 restricted manner. ELISpot assays reveal that SARS-CoV-2-specific CD8 T-cell responses in mild COVID-19 patients are significantly higher than in severe patients, whereas neutralizing antibody responses against SARS-CoV-2 virus significantly correlate with disease severity.

In 2022, the European Union put forward the REPowerEU plan in response to Russia's invasion of Ukraine, aiming at enhancing short-term energy security by diversifying imports and reducing natural gas demand while accelerating the deployment of renewable alternatives in the long term. Here, we quantify the life cycle environmental impacts of both REPowerEU's short-term measures, including the controversial extended coal-fired power plant operations, and how the first year of the crisis was managed in practice. We find that the policy measures' impact on greenhouse gas (GHG) emissions would be negligible, although they could have detrimental effects on other environmental categories.

Forest edges, where humans, mosquitoes, and wildlife interact, may serve as a nexus for zoonotic arbovirus exchange. Although often treated as uniform interfaces, the landscape context of edge habitats can greatly impact ecological interactions. Here, we investigated how the landscape context of forest edges shapes mosquito community structure in an Amazon rainforest reserve near the city of Manaus, Brazil, using hand-nets to sample mosquitoes at three distinct forest edge types.
