Understanding the many roles that G-quadruplexes have in the nervous system not only provides critical insight into fundamental molecular mechanisms that control neurological function, but also provides opportunities to identify novel therapeutic targets to treat injury and disease.There is probably a consensus that psychiatric hospitalization for children and adolescents should be part of a continuum of care, but that given its expense and unnatural nature (children should be with families in a community), as noted by Kyriakopoulos in this issue, it should be used sparingly. Child psychiatrists in both the United States (McClellan) and the United Kingdom (Cotgrove and Northover) rue the fact that resources spent on inpatient units would be better spent on preventing hospitalization or providing better aftercare. It is certainly easy to see that the significant financial cost of a child's inpatient stay might well pay for his or her psychiatric treatment in the community for a year - assuming there were enough well-trained clinicians and resources to provide it. As we describe below, that is the rate-limiting step to providing alternatives and may account for why treatment is centralized rather than kept in communities. Hamdani et al eloquently describe the situation in low- and middle-income countries where there is a dearth of both inpatient and community resources; requiring urgent attention to the provision of holistic care for young people with mental health problems from preventive services upwards. The approach they describe is what our other authors are calling for, due to an historical over-reliance on inpatient beds in higher income countries.
  Orsomucoid protein A (ORM) is a major acute-phase protein. Serum ORM (se-ORM) protein A elevates in infections, malignancies, and autoimmune diseases. Urinary ORM (u-ORM) protein A is more accurate and less invasive marker of inflammation. Elevated u-ORM was associated with pathomechanism factors related to psoriasis such as endothelial dysfunction; however, the clinical significance of it has not been explored yet.
 
  To evaluate se-ORM/u-ORM protein A and urinary orsomucoid protein A/urinary creatinine (u-ORM/u-CREAT) in patient with psoriasis and their relations to severity of the disease.
 
  This case-control study was conducted at Dermatology and Andrology Department; 35 psoriasis patients and 35 age- and sex-matched healthy controls were included. They were subjected to history taking and general and dermatological examination. Psoriasis severity was assessed by Psoriasis Area and Severity Index (PASI) score. Measurement of se-ORM/u-ORM protein A using ELISA and u-ORM/u-CREAT using colorimetric method.
 
  Highly significant difference between psoriasis patients and controls regarding u-ORM protein A level (p value=0.01).  https://www.selleckchem.com/  It was also higher in severe cases than moderate and mild ones and higher in moderate than mild cases (p value 0.001, 0.001, and 0.004, respectively). There were significantly higher u-ORM/u-CREAT (p˂0.001) levels in psoriasis patients than in controls. Also, significantly higher U-ORM/u-CREAT levels were found in severe psoriasis cases than in mild and moderate cases (p=0.003 and 0.006, respectively). While the se-ORM levels showed no significant differences between the studied groups.
 
  u-ORM/u-CREAT is a highly sensitive, easily available, and new inflammatory biomarker of psoriasis which correlates to the disease severity.

  To compare two educational approaches to reduce low back pain in nurses.
 
  A community randomized controlled clinical trial.
 
  Data were collected with two interventions and a control arm between August 2018 and January 2019. Participants were recruited from three hospitals. Hospital 1 received an in-person educational programme, Hospital 2 received via the website and Hospital 3 received nothing. Statistical analysis was carried out with a follow-up of 3 and 6months.
 
  A total of 180 female nurses with low back pain participated in the study. Dimensions of the quality of life improved over 3 and 6months, pain and disability decreased over 3months in both intervention groups and over 6months in the social media group.
 
  Two educational approaches can be effective in decreasing pain, disability and improving quality of life. However, the findings suggest that the social media approach was more successful over the long-term and might be a better way to present the programme.

The Heck-Cassar and Sonogashira protocols, using N-hydroxyethylpyrrolidone (HEP)/water/N,N,N',N'-tetramethyl guanidine (TMG) as green solvent/base mixture and sulfonated phosphine ligands, allowed to recycle the catalyst, always guaranteeing high yields and fast conversion under mild conditions, with aryl iodides, bromides, and triflates. No catalyst leakage or metal contamination of the final product were observed during the HCS recycling. To our knowledge, a turnover number (TON) up to 2375, a turnover frequency (TOF) of 158 h-1 , and a process mass intensity (PMI) around 7 that decreased around 3 after solvent, base, and palladium recovery, represent one of the best results to date using a sustainable protocol. The Heck-Cassar protocol using sSPhos was successfully applied to the telescoped synthesis of Erlotinib (TON 1380; TOF 46 h-1 ).Elucidation of dynamics of molecular rotational motion is an essential part and challenging area of research. We demonstrate reversible diastereomeric interconversion of a molecular rotor composed of overcrowded butterfly-shape alkene (FDF). Its inherent dual rotatory motion (two rotors, one stator) with interconversion between two diastereomers, chiral trans-FDF and meso cis-FDF forms, has been examined in detail upon varying temperatures and solvents. The free energy profile of 180° revolution of one rotor part has a bimodal shape with unevenly positioned maxima (transition states). FDF in aromatic solvents adopts preferentially meso cis-conformation, while in non-aromatic solvents a chiral trans-conformation is more abundant owing to the solvent interactions with peripheral hexyl chains (solvophobic effect). Moderate correlations between the trans-FDF/cis-FDF ratio and solvent parameters, such as refractive index, polarizability, and viscosity were found.
