Temporomandibular disorders (TMD) usually affect the stomatognathic system and can be symptomatic. Patients often self-medicate to relieve symptoms, and this can increase the risk of complications such as adverse drug reactions, overdose, physical and psychological dependence, and delay of appropriate treatment. It is important for dentists to know the prevalence of self-medication to investigate this condition in their patients, thus the primary aim of this study was to estimate the prevalence of self-medication among university students with no TMD, non-painful TMD and painful TMD and the secondary aim was to assess association with independent factors.

Backgrounds: Digital, online assessments are efficient means to detect early cognitive decline, but few studies have investigated the relationship between remotely collected subjective cognitive change and cognitive decline. We hypothesized that the Everyday Cognition Scale (ECog), a subjective change measure, predicts longitudinal change in cognition in the Brain Health Registry (BHR), an online registry for neuroscience research.

Methods: This study included BHR participants aged 55 + who completed both the baseline ECog and repeated administrations of the CANTAB Paired Associates Learning (PAL) visual learning and memory test.

Many older adults report subjective cognitive decline (SCD); however, the specific types of complaints most strongly associated with early disease detection remain unclear. This study examines which complaints from the Everyday Cognition Scales (ECog) are associated with progression from normal cognition to mild cognitive impairment (MCI)/dementia. 415 older adults were monitored annually for 5 years, on average.

Article Synopsis
  • - The study explores the use of 5-aminolevulinic acid (ALA) for enhancing protoporphyrin IX (PpIX) accumulation in pancreatic cancer cells during photodynamic therapy (PDT) and its effectiveness based on tumor nodule size.
  • - Researchers found that drug-resistant Panc1OR pancreatic cancer cells had significantly higher PpIX accumulation and were more susceptible to cell killing at lower light doses compared to their drug-naïve counterparts.
  • - The results suggest that despite aggressive disease progression and poor clinical outcomes, drug-resistant pancreatic cancer cells may respond better to ALA-PDT, indicating a potential for more effective treatment strategies.

The transition from RNA as the informational molecule of primordial biological systems to the DNA genomes of modern organisms represents one of the greatest evolutionary transitions in the history of life. One way to understand this transition is to comprehend the origin of the enzymes responsible for the metabolism of nucleic acid polymers. In the present work, we reconstructed the ancestral sequence of RNA-dependent DNA polymerase (RdDp) and modeled its structure.

Subjective cognitive decline (SCD) is an important part of the aging process and may be a sign of neurodegenerative disease. Current measures of SCD are subject to the limits of retrospective recall of symptoms over a long span of time, which might be addressed by using ecological momentary assessment (EMA) methods. However, there are no currently available measures of SCD validated for use in EMA.
