Paper-based works of art and documents of cultural importance kept in museums and libraries can show notorious signs of deterioration, including foxing stains, caused by fungal colonization. Some of the main chromophore agents of fungal origin that deteriorate paper and therefore affect paper cultural heritage both aesthetically and structurally are the group of pigments called melanins. Thus, knowledge of the diversity and features of fungal melanins and of the melanization pathways of fungi growing on paper is key to removing these pigments from paper-based works of cultural importance. This review provides an approach about the current knowledge of melanins synthesized by paper-colonizing fungi, their localization in the fungal structures, and their role in the deterioration of paper. This knowledge might contribute to developing new, effective, and sustainable strategies of restoration and conservation of historical documents and works of art based on paper.This article examines the relationship between sexual satisfaction and gender, age, social status, being in stable relationships, intercourse frequency, and satisfaction with physical attractiveness (physical appearance and sex appeal). Bomedemstat concentration A self-report questionnaire was applied in a representative sample of 767 residents of Santiago (Chile), over 18 years old and that have had, at least, one sexual relation (with penetration) during their lives. Higher sexual satisfaction was predicted negatively by age and positively by higher satisfaction with sex appeal, higher intercourse frequency and having a stable relationship. Among women, the principal predictors are satisfaction with sex appeal and intercourse frequency. Among men to the above, it is necessary to add satisfaction with physical appearance and having a stable relationship - at odds with supposed higher relevance for women of body satisfaction and sensibility to social relationships. Discussion emphasizes the controversial nature of the gender differences found regarding the Latin American culture.The reconstruction of large-volume soft tissue defects is a major problem in plastic surgery. Many plastic surgeons have focused on external volume expansion (EVE) because of its capacity to promote regeneration of soft tissues, including breast, subcutaneous fat, and skin. EVE is a minimally invasive and less costly tissue engineering approach that has shown great clinical potential. However, many challenges still need to be addressed before such technology can become a common clinical practice. Basic in vivo and in vitro studies have been performed to determine the possible mechanisms by which EVE promotes tissue regeneration and to design optimized animal models. EVE application was found to facilitate cell proliferation and migration, enhance adipogenesis, improve angiogenesis, and provide available space for soft tissue growth. Understanding the mechanical and chemical signals associated with EVE during tissue regeneration may enable the clinical adaptation of this technology. This article reviews the clinical application of EVE techniques, describes preclinical animal models, and evaluates the possible mechanisms by which EVE induces tissue regeneration.

Tourette syndrome (TS) is characterised by the presence of sudden, rapid movements and vocalizations (tics). The nature of tics suggests impairments in inhibitory control. However, findings of impaired inhibitory control have so far been inconsistent, possibly due to small sample sizes, wide age ranges, or not taking medication use or attention-deficit/hyperactivity disorder (ADHD) comorbidity into account.
We investigated group differences in response inhibition using an fMRI-based stop-signal task in 103 8 to 12-year-old children (
= 51 with TS, of whom
= 28 without comorbid ADHD [TS - ADHD] and
= 23 with comorbid ADHD [TS + ADHD]; and
= 52 healthy controls), and related these measures to tic and ADHD severity.
We observed an impaired response inhibition performance in children with TS + ADHD, but not in those with TS - ADHD, relative to healthy controls, as evidenced by a slower stop-signal reaction time, slower mean reaction times, and larger variability of reaction times. Dimensional analyses implicated ADHD severity as the driving force in these findings. Neural activation during failed inhibition was stronger in the inferior frontal gyrus and temporal and parietal areas in TS + ADHD compared to healthy controls.
Impaired inhibitory performance and increased neural activity in TS appear to manifest predominantly in relation to ADHD symptomatology.

This multi-center observational trial included brain-injured adults presenting to the ED, receiving a head computed tomography (CT) and venipuncture for biomarker concentration measurements within 6 h of injury. Subjects had repeat serum sampling and GCS scores every 4 h for the first 24 h, if available for assessment. We analyzed blood samples using an enzyme-linked immunosorbent assay approved by the Food and Drug Administration (FDA). Wilcoxin two-sample test was used to compare initial and repeat serum concentrations for both biomarkers between CT-positive patients who did not have an acute unfavorable neurological outcome and those patients who did.
