The results of our research have shown that both hypotheses can be confirmed. On the general level, there are more similarities in drawing between identical twins compared to non-identical ones; and the differences and similarities become more distinctive throughout the development, especially in figure drawing and in the depiction of space.Capsaicin is an active compound in hot peppers. It has been studied for its health benefits for humans. Optical spectroscopy is an important tool for determining the optical properties or chemical composition of matter. The aim of this research is proposing an optical method to identify and quantify capsaicin in the visible range. To achieve this goal, we combined absorption and diffuse reflectance spectroscopy techniques to compute the extinction coefficient. Moreover, the concentration of the analytes was determined using the optical properties of capsaicin. Our method is a promising tool for developing a classification of capsaicin according to its percentage in chilies. The extinction coefficients are reported for 507nm and 663nm, which are the most significative. In addition, the coefficients to build the mathematical model for capsaicin are reported for Kubelka-Munk model. Finally, a comparison between capsaicin vs chilies spectra was obtained to identify spectral response. Diffuse reflectance signals allowed the identification of capsaicin and opened the possibility of this fast and easy to do method for classification and quantification of bioactive compounds.Constitutive expression of human telomerase reverse transcriptase (hTERT) with DNA methylation of its promoter is a common phenomenon in tumor cells. STF-083010 We recently found that the transcriptional factor Krüppel-like factor 2 (KLF2) binds to the CpG sequences in the hTERT promoter and inhibits hTERT gene expression in normal resting T-cells. The human T-cell line Kit 225 in the resting phase induced by the deprivation of interleukin (IL)-2 showed no decrease in the expression of hTERT, despite the high expression of KLF2. To elucidate the mechanisms of deregulation of hTERT expression in T-cells, we examined the relationship between DNA methylation and KLF2 binding to the hTERT promoter. The hTERT promoter was methylated in Kit 225 cells, resulting in the inhibition of the binding of KLF2 to the promoter. DNA demethylation by the reagent Zebularine recovered KLF2 binding to the hTERT promoter, followed by the downregulation of its gene expression. These findings indicate that the repressive effect of KLF2 on hTERT gene expression is abolished by DNA methylation in T-cell lines.

Research into paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) has focused on tertiary level management. This review reports on symptoms and investigations at presentation.

Single centre retrospective case note analysis of patients fulfilling PIMS-TS diagnostic criteria from March to May 2020 in a London district level university hospital.

Six patients presented in the week prior to their final diagnosis with fever and non-specific symptoms. Raised C-reactive protein (CRP), lymphopenia and hyponatraemia were noted. Kawasaki-like symptoms were under-represented in all patients.

The results suggest that a proportion of children with early PIMS-TS present with a non-specific febrile illness and abnormal blood results. Further research is needed to determine the most appropriate identification and follow-up of these children.

The Pacific Islands have among the highest rates of ear disease and hearing loss in the world, especially among children. Given that Ear, Nose and Throat (ENT)/audiology specialists are limited in the region, the successful implementation of ear and hearing health services will depend on the participation and support of the wider community of health professionals. There are currently no studies from the Pacific Islands investigating the knowledge and attitudes of either health students or health professionals towards childhood hearing loss and hearing services.

Survey of medical and nursing students (n=370) currently enrolled at the National University of Samoa. Students will independently and anonymously complete a 10-item questionnaire. The questions assess attitudes to childhood hearing loss (two questions), knowledge of aetiology of childhood hearing loss (three questions), and knowledge of identification and interventions for children with hearing loss (five questions). Responses are based on a 5-point Likert scale (Strongly agree/Agree/Neutral/Disagree/Strongly disagree).

We publish these protocols to facilitate similar studies in other low-income and middle-income countries, and especially among our Pacific Island neighbours.

Recent data indicate that infertile men have an increased risk of somatic disorders such as cancer and die younger compared to fertile men. Moreover, several studies point to a significant adverse effect on the health of the offspring. From the startling lack of progress in male contraception combined with the paucity of improvements in the diagnosis of male infertility, we conclude there is a crisis in male reproductive health. The Male Reproductive Health Initiative has been organized to directly address these issues (www.eshre.eu/Specialty-groups/Special-Interest-Groups/Andrology/MRHI). The Working Group will formulate an evidence-based strategic road map outlining the ways forward. This is an open consortium desiring to engage with all stakeholders and governments.

Emerging evidence suggests older adults may experience subtle hemothoraces that progress over several days. Delayed progression and delayed development of traumatic hemothorax (dHTX) have not been well characterized. We hypothesized dHTX would be infrequent but associated with factors that may aid prediction.

We retrospectively reviewed adults aged ≥50 years diagnosed with dHTX after rib fractures at two level 1 trauma centers (March 2018 to September 2019). dHTX was defined as HTX discovered ≥48 hours after admission chest CT showed either no or 'minimal/trace' HTX. Two blinded, board-certified radiologists reviewed inpatient chest imaging and classified injury patterns according to Chest Wall Injury Society (CWIS) taxonomy. Descriptive analysis was performed for demographic and hospitalization characteristics.

We identified 14 patients with pooled dHTX rate of 1.3%. After initial chest CT negative for concerning hemothoraces, the patients did not undergo follow-up imaging until new symptoms (shortness of breath, chest pain) developed eight (57%) were not diagnosed until after discharge from initial hospitalization (mean (range) 9 (2-20) days after discharge).
