Because of the poor link between psychiatric diagnosis and neurobiological findings, it is difficult to classify mental disorders. The changes made to psychiatric diagnostic systems over the years can be understood in terms of "practical conservatism." The Diagnostic and Statistical Manual of Mental Disorders (DSM)-I and DSM-II were theoretically supported by the psychoanalytic and psychodynamic approach. Subsequently, psychiatric diagnoses of this kind were opposed by the anti-psychiatry movement, as well as by the findings of the Rosenhan experiment. ⋯ To overcome the limitations of the categorical approach, psychiatrists have considered adopting a dimensional approach. However, their efforts were frustrated in the DSM-5 revision process. Thus, the DSM-5 is characterized by the rearrangement of psychiatric diagnoses, the partial adoption of a dimensional approach, the introduction of new diagnoses, and harmonization with the International Classification of Diseases.

Behavioral cognitive therapy is recommended for lung cancer-related pain. The aim of the study was to analyze the strategies of coping with pain in relation to the histological type of lung cancer. The study included 257 lung cancer patients, divided into small cell lung carcinoma (SCLC) group (n = 72) and non-small cell lung carcinoma (NSCLC) group (n = 185). ⋯ The significant independent determinants of pain perception in the NSCLC group were: pain control strategy (β = -0.39) and coping self-statement (β = 0.72). We conclude that in NSCLC patients both pain control and the ability to decrease pain are the strategies which decrease the intensity of perceived pain. In contrast, SCLC patients have no clear strategy for pain-coping.

In order to provide a theoretical basis for the amelioration of heat stress-related diseases in broilers by taurine supplementation, the effect of taurine on the viability and antioxidant ability of aortic endothelial cells in broilers under heat stress was investigated in the present study. In this experiment, 10d healthy broilers were sacrificed, then aortic tissue was used for aortic endothelial cells isolation and cultivation. Tissue patching was used to cultivate primary broiler aortic endothelial cells. ⋯ Compared with the HS group, the taurine groups showed significantly higher level in relative survival rates (P < 0.05), and significantly lower apoptosis rates (P < 0.05); (2) compared to control group, LDH activity and MDA content of endothelial cells in the HS group were significantly increased (P < 0.01), while the levels of T-SOD, GSH-Px and T-AOC were significantly decreased (P < 0.01). The LDH activity and MDA content of endothelial cells were significantly lower in Tau group than those of HS group (P < 0.05), while the T-SOD activity, GSH-Px activity and T-AOC of endothelial cells were significantly increased (P < 0.05) in the taurine group. The results show that HS decreases antioxidant capacity, which causes severe oxidative damage to the endothelial cells; while taurine administration prevents the decline in LDH activity and MDA content, and increases the activity of several antioxidant enzymes, including SOD, GSH-Px and T-AOC, which implies that taurine can improve the broiler aortic endothelial cells activity and antioxidant ability under heat stress.

The first massive open online courses or MOOCs were offered in 2008 in the USA, since then MOOCs have hit the higher education (HE) section by storm and have continued to grow rapidly since 2012, with hundreds of HE establishments across the globe engaged in providing MOOCs. MOOCs are online courses that are open to everyone and anyone to join with typically no limits to the number of participants or prerequisite qualifications. In some MOOCs there is an option to pay for a certificate upon completion. ⋯ There is also a growing use of MOOCs in higher education as a recourse for campus degree programmes, known as hybrid MOOCs, where the MOOC provides the learning and the assessment is undertaken by the educational institution. The growing number of MOOCs available for credit is changing the way some learners are accessing higher education and the development of micro degrees obtained through the completion of a number of MOOCs may potentially change the way higher education is provided in the future. Finally, the potential of artificial intelligence to provide virtual classroom assistants is also a possible game changer, allowing more personalised learning to be delivered at scale.

Short upstream open reading frames (uORFs) are cis-acting elements located within the 5'-leader sequence of transcripts and are defined by an initiation codon in-frame with a termination codon located upstream or downstream of its main ORF (mORF) initiation codon. Recent genome-wide ribosome profiling studies have confirmed the widespread presence of uORFs and have shown that many uORFs can initiate with non-AUG codons. uORFs can impact gene expression of the downstream mORF by triggering mRNA decay or by regulating translation. Thus, disruption or creation of uORFs can elicit the development of several genetic diseases. ⋯ We also show some examples of uORF deregulation in human genetic diseases, focusing mainly on cancer. The knowledge of how uORF deregulation drives the onset of a disease, points out the need to screen the 5'-leader sequences of the transcripts in search for potential disease-related variants. This information will be relevant for the implementation of new diagnostic and/or therapeutic tools.
