The lead compounds also exhibited notable IC50 values against another breast cancer cell line, MCF-7. Furthermore, it was observed that these compounds were relatively nontoxic to normal cell lines HEK293 (human embryonic kidney cell line) and MCF12A (nontumorigenic human breast epithelial cell line). The IC50 values against healthy cells were at least 5- to 11-fold higher, offering a new class of heterocycles that can be further developed as promising therapeutics for cancer treatment.
Population-based studies assessing the factors associated with use of and need for dental prosthesis among older adults are scarce.
To evaluate the use of and need for dental prosthesis and associated factors in the older adult population of a southern city of Brazil.
A cross-sectional study, involving community-dwelling older adults (≥60years), was performed. A probabilistic per cluster sampling was used, and 282 participants from Veranópolis, Brazil, were included. A clinical oral health examination was performed, and a structured questionnaire was applied. Bivariate and multivariate analyses were performed to verify associations using Poisson regression with robust variance.
The prevalence of use of dental prosthesis was 87.2% (n=246), while the prevalence of need for dental prosthesis was 27% (n=76). Older adults with medium/high levels of education had 17.8% (P=.019) lower prevalence ratio (PR) for use of dental prosthesis. Unmarried and retired older adults had, respectively, 11.1% (PR1.111; 95%CI1.022-1.207) and 19.5% (PR1.195; 95%CI1.009-1.415) higher PR for use of prosthesis. Those without access to dental care had 11.8% (P=.012) higher PR for use of dental prosthesis. Older adults living in rural areas had 64.7% (PR1.647; 95%CI1.079-2.514) higher PR of need for dental prosthesis.
High and low prevalence of use of and need for dental prosthesis, respectively, were detected in this sample. Level of education, marital status, retirement status and access to dental care were associated with the use of dental prostheses. However, only residence area was associated with the need for oral rehabilitation.

Our aim was to investigate the role of the brain-derived neurotrophic factor (BDNF)/tyrosine kinase B (TrkB)/cAMP-response element-binding protein (CREB) signaling pathway in BPS-induced cytotoxicity in SK-N-SH cells. The cells were treated with various concentrations of BPS, and cell viability, apoptosis rate, mitochondrial membrane potential (MMP), and the BDNF, cleaved-caspase-3, B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), TrkB, CREB, and phospho-CREB (p-CREB) levels were determined. selleckchem The effects of pretreatment with the TrkB activator 7,8-dihydroxyflavone (7,8-DHF) were also explored. BPS decreased SK-N-SH cell viability and altered their morphology. Their apoptosis rate was increased, as were the levels of the proapoptotic proteins Bax and cleaved-caspase-3, but MMP was decreased. Thus, BPS may induce mitochondria-dependent apoptosis pathways. BPS also reduced the BDNF, TrkB, and p-CREB levels, and pretreatment with 7,8-DHF alleviated its cytotoxic effects. Thus, BPS-induced cytotoxicity might be mediated by the BDNF/TrkB/CREB signaling pathway.
To describe the efficacy and safety of intranasal midazolam for sedation during essential dental treatment of geriatric patients with major neurocognitive disorder (MND) and care-resistant behaviour (CRB).
Dental treatment is often impossible in geriatric MND patients with CRB. Intranasal midazolam may provide a non-invasive sedation method, but there is currently no information on its use in geriatric patients.
In this observational study, we included geriatric patients with severe MND and CRB needing urgent dental treatment. Each patient received 5mg midazolam intranasally. Agitation/sedation levels, heart rate, respiration rate and oxygen saturation were recorded at 5-minute intervals.
Thirty two patients were included. Mean age was 84 (±7) years. Mean (SD) time to treatment start was 13 (±5) minutes, and mean time to maximum sedation 17 (±11) minutes. Sedation was sufficient to enable dental treatment to be completed in 31 (97%) patients. Anxiolysis/light sedation occurred in 16 (50%) patients, and moderate to deep sedation occurred in 16 (50%) patients. No patients suffered from apnoea, although 3 patients required a chin-lift manoeuvre. Hypoxaemia occurred in 1 of these patients and in 2 other patients without airway obstruction. All patients recovered uneventfully. In a regression model, age, weight and other sedative medication use were found not to be associated with maximum sedation depth.
Of 5mg intranasal midazolam facilitates treatment of geriatric patients with MND in the comfort of their own environment. More information is needed to guide titration to balance the desired sedation level and patient safety.

Thus, the long-term success of biodiversity conservation depends on a thorough understanding of human-nature interactions. Such interactions are ubiquitous but vary greatly in time and space and are difficult to monitor efficiently at large spatial scales. However, the Information Age also provides new opportunities to better understand human-nature interactions because many aspects of daily life are recorded in a variety of digital formats. The emerging field of conservation culturomics aims to take advantage of digital data sources and methods to study human-nature interactions and thus to provide new tools for studying conservation at relevant temporal and spatial scales. Nevertheless, technical challenges associated with the identification, access, and analysis of relevant data hamper the wider adoption of culturomics methods. To help overcome these barriers, we propose a conservation culturomics research framework that addresses data acquisition, analysis, and inherent biases.
