Cyclophilin A (CypA) is a ubiquitous and highly conserved protein. CypA, the intracellular target protein for the immunosuppressant cyclosporine A (CsA), plays important cellular roles through peptidyl-prolyl cis-trans isomerase (PPIase). Increasing evidence shows that CypA is up-regulated in a variety of human cancers. In addition to being involved in the occurrence and development of multiple tumors, overexpression of CypA also has been shown to be strongly associated with malignant transformation. Surgery, chemotherapy and radiotherapy are the three main treatments for cancer. Chemotherapy and radiotherapy are often used as direct or adjuvant treatments for cancer. However, various side effects and resistance to both chemotherapy and radiotherapy bring great challenges to these two forms of treatment. According recent reports, CypA can improve the chemosensitivity and/or radiosensitivity of cancers, possibly by affecting the expression of drug-resistant related proteins, cell cycle arrest and activation of the mitogen-activated protein kinase (MAPK) signaling pathways. In this review, we focus on the role of CypA in cancer, the impact on cancer chemotherapeutic and radiotherapy sensitivity, and the mechanism of action. this website It is suggested that CypA may be a novel potential therapeutic target for cancer chemotherapy and/or radiotherapy.

To identify and characterize peptide binders to truncated recombinant chikungunya virus envelope protein 2.

Despite extensive research on the chikungunya virus (CHIKV), the specific antiviral treatment's unavailability has stressed the need for the urgent development of therapeutics. The Envelope protein 2 (E2) of CHIKV that displays putative receptor binding sites and specific epitopes for virus neutralizing antibodies is a critical target for the therapeutic intervention.

The study aims to identify the unique peptides that can bind to truncated E2 protein of CHIKV and further explore their properties as potential therapeutic candidate.

A stretch of CHIKV-E2 (rE2), which is prominently exposed on the surface of virion, was used as bait protein to identify peptide binders to the CHIKV-rE2 using a 12-mer phage display peptide library. Three rounds of biopanning yielded several peptide binders to CHIKV-rE2 and their binding affinities were compared by phage ELISA. Additionally, a fully flexible-blind docking simulation investigated the possible binding modes of the selected peptides. Furthermore, the selected peptides were characterized and their ADMET properties were explored in silico.

Five peptides were identified as potential binders based on their robust reactivity to the bait protein. The selected peptides appeared to interact with the crucial residues that were notably exposed on the surface of E1-E2 trimeric structure. The explored in silico studies suggested their non-allergenicity, non-toxicity and likeliness to be antiviral.

The potential binding peptides of CHIKV-rE2 protein were identified using phage display technology and characterized in silico. The selected peptides could be further used for the development of therapeutics against the CHIKV infection.

This ready availability is linked with abuse. Previous literature describes medicine abuse from pharmacists' and general public perspectives. Here we investigate experiences of 17 men in addiction treatment in Amman (21-39 years) of obtaining psychoactive medicines. Alprazolam, clonazepam, bromazepam and tramadol were most commonly abused. Psychoactive medicines were obtained from street dealers, but pharmacies were preferred. Regulations appears ineffective; lack of understanding of pharmacists of the abuse potential of some medicines was perceived; 'softening rules' on supply was attributed to cultural and social norms around familiarity.

Studies of mechanically ventilated patients with a low risk of reintubation have suggested that the use of high-flow nasal cannula (HFNC) oxygen therapy reduces the risk of reintubation compared with conventional oxygen therapy (COT). However, the effect of HFNC following extubation in elderly patients with a high risk of reintubation remains unclear.

All consecutive medical intensive care unit (ICU) patients aged >65 years who were mechanically ventilated for >24 h were prospectively registered between July 2017 and June 2018. Control was obtained from a historical database of patients attending the same ICU from January 2012 to December 2013. A total of 152 patients who underwent HFNC after planned extubation according to institutional protocols (HFNC group) were compared with a propensity-matched historical control group who underwent COT (

 = 175, COT group). The primary outcome was the proportion of reintubated patients within 48 h after planned extubation.

One hundred patients from the HFNC reviews of this paper are available via the supplemental material section.

Respiratory viral infections, particularly influenza, are known to cause significant morbidity and mortality, often due to secondary infections. Our aim was to comparatively analyze the incidence, epidemiology, and outcomes of secondary pneumonia in adult patients hospitalized with influenza

noninfluenza viral infections and determine whether influenza particularly predisposes to secondary infections.

This was a retrospective analysis from a single tertiary medical center of adult patients admitted to the hospital between 2008 and 2010 with respiratory viral infections. Microbiological patterns and clinical outcomes were compared between those with influenza (VI,

 = 57) and those with noninfluenza (NI,

 = 77) respiratory viral infections.

The NI group was older (60.6 ± 14.0

53.3 ± 19.7 years,

 = 0.019) with higher rates of lung transplantation (29%

9%,

 = 0.009) than VI. Overall, 35% developed secondary pneumonia, higher among NI (44%) than VI (23%,

 = 0.017).

was the most common cause of pneumonia in VI, whereas Gram-negative rods were most frequently identified in NI.
