A broad range of cell lines with characteristic features are used as bio-factories to produce recombinant proteins for basic research and therapeutic purposes. Genetic engineering strategies have been used to manipulate the genome of mammalian cells, insects, and yeasts for heterologous expression. One reason is that the glycosylation pattern of the expression hosts differs somehow from mammalian cells, which may cause immunogenic reactions upon administration in humans. CRISPR-Cas9 is a simple, efficient, and versatile genome engineering tool that can be programmed to precisely make double-stranded breaks at the desired loci. Compared to the classical genome editing methods, a CRISPR-Cas9 system is an ideal tool, providing the opportunity to integrate or delete genes from the target organisms. Besides broadened applications, limited studies have used CRISPR-Cas9 for editing the endogenous pathways in expression systems for biopharmaceutical applications. In the present review, we discuss the use of CRISPR-Cas9 in expression systems to improve host cell lines, increase product yield, and humanize glycosylation pathways by targeting intrinsic genes. Olfactory sensory neurons and the olfactory mucosa are both important for optimal olfactory function. The potential nasal mucosal toxicity of chemotherapy regimens has not been assessed yet. The aim of this study was to objectively investigate the effect of chemotherapy on mucociliary clearance and olfactory function and to evaluate whether this effect differs between different chemotherapy regimens and age groups. The study included consecutive patients admitted for the treatment of a variety of primary tumors (except head and neck and brain malignancies). Patients were evaluated for olfaction and mucociliary clearance before and immediately after completing the last session of chemotherapy cycles, according to the therapeutic protocol. For objective evaluation, the saccharine test was used for mucociliary clearance and the Sniffin' Sticks test for olfactory function. Of the 46 initial patients, 30 completed the study. Groups were formed according to the chemotherapy regimen (four groups CA (doxorubicin to be more profound in younger patients, which could have been due to higher initial scores. Chemotherapy impairs both the mucociliary clearance and olfactory function in cancer patients. https://www.selleckchem.com/products/Decitabine.html This might reflect the collective negative effect of chemotherapy on olfactory function, not only through the neurocytotoxic effect but also the cytotoxic effect on the nasal mucosa. In addition, the reduction in olfactory threshold and total olfactory function scores was seen to be more profound in younger patients, which could have been due to higher initial scores. Comparison of the effects of trospium and solifenacin used for the treatment of overactive bladder (OAB) on intraocular pressure (IOP) and tear secretion. This study was planned as a prospective study and was conducted at a single center between October 2014 and April 2016. OAB patients were included in the study following an ophthalmic examination, IOP measurement with an applanation tonometer, and tear secretion measurement with the Schirmer I test in the ophthalmology outpatient department. The patients were started with trospium 30mg oral bid or solifenacin 5mg oral qd. They were then followed up at the 4th and 12th weeks. A total of 225 OAB patients with a mean age of 47.80 (18-75) years were evaluated. The mean age was 47.41 ± 12.65years in the trospium group (n = 104) and 48.14 ± 11.82years in the solifenacin group (n = 121) with no statistically significant difference. When the two medications were compared, no statistically significant difference was observed at the 4th and 12th weeks in terms of IOP (p = 0.988, p = 0.822) and dry eye (p = 0.764, p = 0.581). No statistically significant difference was observed between trospium and solifenacin in terms of their effects on IOP and tear secretion in OAB patients. We therefore concluded that the effects of trospium and solifenacin on IOP and tear secretion changes were similar in OAB patients without comorbidities.

The thyrotropin receptor (TSHR) is the key autoantigen in Graves' disease (GD) and associated orbitopathy (GO). Antibodies targeting the TSHR (TSHR-Ab) impact the pathogenesis and the course of GO. This review discusses the role and clinical relevance of TSHR-Ab in GO. Review of the current and pertinent literature. GO is the most common extrathyroidal manifestation of GD and is caused by persistent, unregulated stimulation of TSHR-expressing orbital target cells (e.g. fibroblasts and pre-adipocytes). Serum TSHR-Ab and more specifically, the stimulatory Ab (TSAb) are observed in the vast majority of patients with GD and GO. TSHR-Ab are a sensitive serological parameter for the differential diagnosis of GO. TSHR-Ab can be detected either with conventional binding immunoassays that measure binding of Ab to the TSHR or with cell-based bioassays that provide information on their functional activity and potency. Knowledge of the biological activity and not simply the presence or absence of TSHR-Ab has relevant clinical implications e.g. predicting de-novo development or exacerbation of pre-existing GO. TSAb are specific biomarkers of GD/GO and responsible for many of its clinical manifestations. TSAb strongly correlate with the clinical activity and clinical severity of GO. Further, the magnitude of TSAb indicates the onset and acuity of sight-threatening GO (optic neuropathy). Baseline serum values of TSAb and especially dilution analysis of TSAb significantly differentiate between thyroidal GD only versus GD + GO. Measurement of functional TSHR-Ab, especially TSAb, is clinically relevant for the differential diagnosis and management of GO.
