BACKGROUND: The common sense model (CSM) proposes that illness perceptions guide coping and illness management, which subsequently affects outcomes. Chronic fatigue syndrome (CFS) is associated with severe functional impairment. CFS is distinct from other physical health conditions in that individuals can experience high levels of uncertainty, stigma and disbelief from others. This study aimed to compare illness perceptions in adolescents with CFS with other physical health conditions, using a cross-sectional, between-groups design...

BACKGROUND: Locally advanced muscle-invasive bladder cancer (MIBC) patients who are candidates for radical cystectomy (RC) should receive perioperative chemotherapy (CHT). However, the adherence to CHT guidelines is low. Thus, we tested contemporary CHT use rates and associated cancer-specific mortality (CSM) and overall mortality (OM) rates. MATERIALS AND METHODS: Within the SEER database (2004-2015), we identified pT3N0/+ MIBC patients, who underwent RC, with or without perioperative CHT...

Microbial spoilage causes food losses in the food industry and as such, the use of synthetic chemical preservatives is still required. The current study proposes the use of agro-waste, i.e., grape pomace extracts (GPE), as production medium for biopreservation compounds. Production kinetics, subsequent to optimization using response surface methodology (RSM) for biopreservation compounds production was studied for three yeasts using GPE broth as a fermentation medium. The results showed that the highest volumetric zone of inhibition (VZI) was 1...

With approximately 20 % of pregnancies ending in loss, miscarriage is a relatively common and stressful occurrence. Because romantic partners' coping efforts are intimately connected, the way one partner copes with the other's miscarriage has important implications for individual and relational well-being. Grounded in the communicated sense-making (CSM) model, the current study investigated how cis-gender men in heterosexual marriages (n = 45) communicatively constructed the meaning of their wife's miscarriage through metaphors...

Jakob T Rostøl, Luciano A Marraffini
Type III-A CRISPR-Cas systems employ the Cas10-Csm complex to destroy bacteriophages and plasmids, using a guide RNA to locate complementary RNA molecules from the invader and trigger an immune response that eliminates the infecting DNA. In addition, these systems possess the non-specific RNase Csm6, which provides further protection for the host. While the role of Csm6 in immunity during phage infection has been determined, how this RNase is used against plasmids is unclear. Here, we show that Staphylococcus epidermidis Csm6 is required for immunity when transcription across the plasmid target is infrequent, leading to impaired target recognition and inefficient DNA degradation by the Cas10-Csm complex...

The CRISPR-Cas system is the prokaryotic immune response that destroys invading foreign nucleic acids. Based on the architecture and distinct mechanism of targeting, the CRISPR-Cas system is classified into six types (I-VI). The Csm complex belongs to the type III system and consists of five subunits (Cas10 and Csm2-5) and a crRNA. The Csm complex targets RNA and RNA-dependent single-strand DNA. Here, we present a protocol for in vitro reconstitution of a Csm complex from a hyperthermophilic archaeon Thermococcus onnurineus NA1 (ToCsm complex)...

INTRODUCTION: Diagnostic tests for vascular erectile dysfunction (ED) depend on cavernous smooth muscles (CSM) relaxation following an intracorporal injection (ICI). Enhanced sympathetic tone, which is not uncommon during performance of these tests, can bias its results. Also, CSM diseases can cause veno-occlusive diseases (VOD) ED. Corpus cavernosum electromyography (CC-EMG) potentials' amplitudes represent the integrated sympathetic activity of healthy CSM. Stem-cells and gene-therapy are potential therapeutic options for impaired CSM...
