Dyspareunia is a genital pain during or after penile-vaginal sexual intercourse. It is a painful spasm of the pelvic muscles that partly or entirely disables vaginal penetration.

We examined the effect of extracorporeal shock wave therapy (ESWT) on idiopathic non-organic dyspareunia in women. A prospective, randomized, double-blind, placebo-controlled study was conducted.

The study included 62 women who reported dyspareunia. Patients in the treatment and placebo groups received ESWT perineally weekly for 4 consecutive weeks; placebo patients received placebo stand-off treatment. The grade of dyspareunia was estimated by using the Marinoff Dyspareunia Scale and subjective pain intensity on a visual analog scale (VAS) before and after treatment. Follow-ups were conducted 1, 4 and 12 weeks after the final ESWT session.

The study included 61 women. The treatment but not placebo group differed by the Marinoff Dyspareunia Scale and VAS. Differences before and after treatment within groups were all P<0.001 and between groups, P<0.001. Pain reduction was always>30%. The effect sizes were both large Marinoff 0.825 and VAS 0.883.

ESWT significantly reduced subjective pain in our women treated for dyspareunia.

Sexual dysfunction after stroke is common and is associated with poor health and quality of life outcomes. Clinical guidelines for stroke typically recommend that all stroke survivors have access to support relating to sexuality during rehabilitation. However, the extent to which rehabilitation professionals are prepared to address sexuality after stroke is unclear.

To investigate the knowledge, comfort, approach, attitudes, and practices of rehabilitation professionals toward supporting stroke survivors with their sexuality concerns.

Cross-sectional analytic survey design. Data were collected by using an electronic questionnaire that contained the Knowledge, Comfort, Approaches, and Attitudes towards Sexuality Scale (KCAASS) and sexuality-related practice questions. Participants were recruited from Australia, New Zealand, the United States, Canada, United Kingdom, Ireland, Singapore, and South Africa. Multiple regression was used to explore KCAASS scores and sexuality-related practices.

A total of 95ilitation. The timing of training predicted knowledge (t = 3.99; p<0.001), comfort (t = 3.47; p<0.001) and the provision of sexuality-rehabilitation services (t = 3.68; p<0.001).

Findings confirm that sexuality is neglected in stroke rehabilitation and point to the need for a considered approach to the timing and nature of education.

Adjunct therapies (ATs) may further improve outcomes after botulinum toxin injections in spastic patients, but evidence was unclear in previous systematic reviews.

To assess the efficacy of non-pharmacological ATs in spastic adults according to the International Classification of Functioning, Disability and Health and build an expert consensus based on a Delphi process.

Four electronic databases were searched up to May 2020 for reports of comparative trials of non-pharmacologic ATs after botulinum toxin injections in spastic adults. Then 25 French experts participated in a two-round Delphi process to build recommendations on the use of ATs.

We included 32 studies (1202 participants, median 32/study) evaluating the effects of physical agents (n=9), joint posture procedures (JPPs, n=11), and active ATs (n=14), mainly after stroke. The average quality of articles was good for randomised controlled trials (median [interquartile range] PEDro score = 7 [6-8]) but moderate (n=2) or poor (n=2) for non-randomi individual treatment goals, participation and quality of life. Review Registration. PROSPERO (CRD42018105856).
JPPs and active ATs (device-assisted or device-free) may further improve impairments and activities after botulinum toxin injections. Further studies are needed to better define the best strategies for ATs as a function of the individual treatment goals, participation and quality of life. Review Registration. PROSPERO (CRD42018105856).
The parotid gland is a major salivary gland that has important roles in the digestive and immune system. HSP990 manufacturer Peroxisomes are ubiquitous, single-membrane-bound organelles that are present in all eukaryotic cells. Peroxisomes help mediate lipid and reactive oxygen species metabolism, as well as polyunsaturated fatty acid, cholesterol and plasmalogen synthesis. Much of the knowledge on peroxisomes has derived from metabolic organs, however no detailed knowledge is available on peroxisomes in the parotid glands. We thus aimed to comprehensively delineate the localization and characterization of peroxisomal proteins in the murine parotid gland.

We characterized peroxisomes in the acinar and striated duct cells of the murine parotid gland by fluorescence and electron microscopy, as well as protein and mRNA expression analyses for important peroxisomal genes and proteins.

We found that peroxisomes are present in all cell types of the mouse parotid gland, however, exhibit notable cell-specific differences in their abundance and enzyme content. We also observed that mouse parotid glands contain high levels of peroxisomal β-oxidation enzymes (including Acox1, Mfp2 and Acaa1), catalase and other peroxisomal anti-oxidative enzymes.

This data suggests that peroxisomes are highly abundant in the murine parotid gland and might help to protect against oxidative stress. This comprehensive description of peroxisomes in the parotid gland lays the groundwork for further research concerning their role in the pathogenesis of parotid gland diseases and tumors.

The focus of this study was to heterologously express and characterise a keratinolytic enzyme produced by C. carnipullorum. Chryseobacterium carnipullorum secretes proteolytic enzymes that have feather degrading capabilities during its exponential growth phase. This study concluded that the most likely main component of the keratinolytic enzymes of C. carnipullorum was peptidase M64, a serine-endopeptidase with a molecular weight in crude form of 49.46 kDa. Primers were designed on the selected gene of interest, which was amplified from the genome of C. carnipullorum (accession number NZ-FRCD01000002.1). The gene coding for peptidase M64 was further cloned, propagated and expressed in E. coli BL21 [DE3] cells. Purification was by Immobilised Metal Affinity Chromatography (IMAC). The molecular weight of the keratinase was about 50 kDa after purification while its optimum temperature and pH were 50 °C and 8.5, respectively. The activity of this keratinase was inhibited by phenylmethylsulfonyl fluoride (PMSF) and it was enhanced by the presence of divalent metal ions such as Mg2+ and Ca2+. Enzyme activity was further assayed by application to chicken feathers and observed degradation was an indication of keratinolytic potential.Nucleoside-modified messenger RNA (mRNA)-lipid nanoparticles (LNPs) are the basis for the first two EUA (Emergency Use Authorization) COVID-19 vaccines. The use of nucleoside-modified mRNA as a pharmacological agent opens immense opportunities for therapeutic, prophylactic, and diagnostic molecular interventions. In particular, mRNA-based drugs may specifically modulate immune cells, such as T lymphocytes, for immunotherapy of oncologic, infectious and other conditions. The key challenge, however, is that T cells are notoriously resistant to transfection by exogenous mRNA. Here, we report that conjugating CD4 antibody to LNPs enables specific targeting and mRNA interventions to CD4+ cells, including T cells. After systemic injection in mice, CD4-targeted radiolabeled mRNA-LNPs accumulated in spleen, providing ∼30-fold higher signal of reporter mRNA in T cells isolated from spleen as compared with non-targeted mRNA-LNP. Intravenous injection of CD4-targeted LNP loaded by Cre recombinase-encoding mRNA provided specific dose-dependent loxP-mediated genetic recombination, resulting in reporter gene expression in about 60% and 40% of CD4+ T cells in spleen and lymph nodes, respectively. T cell phenotyping showed uniform transfection of T cell subpopulations, with no variability in uptake of CD4-targeted mRNA-LNP in naive, central memory, and effector cells. The specific and efficient targeting and transfection of mRNA to T cells established in this study provides a platform technology for immunotherapy of devastating conditions and HIV cure.CRISPR-Cas9 is rapidly entering molecular biology and biomedicine as a promising gene-editing tool. A unique feature of CRISPR-Cas9 is a single guide RNA directing a Cas9 nuclease towards its genomic target. Herein, we highlight new approaches for improving cellular uptake and endosomal escape of CRISPR-Cas9. As opposed to other recently published works, this review is focused on non-viral carriers as a means to facilitate the cellular uptake of CRISPR-Cas9 through endocytosis. The majority of non-viral carriers, such as gold nanoparticles, polymer nanoparticles, lipid nanoparticles and nanoscale zeolitic imidazole frameworks, are developed with a focus towards optimizing the endosomal escape of CRISPR-Cas9 by taking advantage of the acidic environment in the late endosomes. Among the most broadly used methods for in vitro and ex vivo ribonucleotide protein transfection are electroporation and microinjection. Thus, other delivery formats are warranted for in vivo delivery of CRISPR-Cas9. Herein, we specifically revise the use of peptide and nanoparticle-based systems as platforms for CRISPR-Cas9 delivery in vivo. Finally, we highlight future perspectives of the CRISPR-Cas9 gene-editing tool and the prospects of using non-viral vectors to improve its bioavailability and therapeutic potential.N-Acetylgalactosamine (GalNAc) conjugated small interfering RNA (siRNA) are a leading RNA interference (RNAi) platform allowing targeted inhibition of disease-causing genes in hepatocytes. More than a decade of development has recently resulted in the first approvals for this class of drugs. While substantial effort has been made to improve nucleic acid modification patterns for better payload stability and efficacy, relatively little attention has been given to the GalNAc targeting ligand. In addition, the lack of an intrinsic endosomal release mechanism has limited potency. Here we report a stepwise analysis of the structure activity relationships (SAR) of the components comprising these targeting ligands. We show that there is relatively little difference in biological performance between bi-, tri- and tetravalent ligand structures, while identifying other features that affect their biological activity more significantly. Further, we demonstrate that subcutaneous co-administration of a GalNAc-functionalized, pH responsive endosomal release agent markedly improved the activity and duration of effect for siRNA conjugates, without compromising tolerability, in non-human primates.
