Although the immunomodulatory effects of these antigens are well known, the effects attributed to their protease activities are not thoroughly investigated. We set out to determine the effects of house dust mite (HDM) allergens with varying protease activities on bronchial epithelial cell functions. Materials and methods BEAS-2B cells were maintained in ALI-culture and stimulated with Der p1 (cysteine protease), Der p6 (serine protease), and Der p2 (non-protease) with and without specific protease inhibitors or heat denaturation. Cell viability and epithelial permeability were measured with MTT and paracellular flux assay, respectively. The effect of heat denaturation on allergen structure was examined using in silico models. Matrix metalloproteinases (MMPs) were investigated at the transcription (qPCR), protein (ELISA), and functional (zymography) levels. Results Epithelial permeability increased only after Der p6 but not after Der p1 or Der p2 stimulation. Der p2 increased both MMP-2 and MMP-9 expression, while Der p1 increased only MMP-9 expression. The heat-denatured form of Der p1 unexpectedly increased MMP-9 gene expression, which, through the use of in silico models, was attributed to its ability to change receptor connections by the formation of new electrostatic and hydrogen bonds. IL-8 and GM-CSF production were increased after Der p1 and Der p2 but decreased after Der p6 stimulation. IL-6 decreased after Der p1 but increased following stimulation with Der p6 and heat-denatured Der p2. Conclusion Allergens in house dust mites are capable of inducing various changes in the epithelial cell functions by virtue of their protease activities.Stigma in health care settings can have negative consequences on women living with HIV, such as increasing the likelihood of missed visits and reducing trust in their clinical providers. Informed by prior stigma research and considering knowledge gaps related to the effect of patient-provider race concordance, we conducted this study to assess if patient-provider race concordance moderates the expected association between HIV-related stigma in health care settings and patients' trust in their providers. Moderation analyses were conducted using Women's Interagency HIV Study data (N = 931). We found significant main effects for patient-provider race concordance. Higher experienced stigma was associated with lower trust in providers in all patient-provider race combinations [White-White B = -0.89, standard error (SE) = 0.14, p = 0.000, 95% confidence interval, CI (-1.161 to -0.624); Black patient-White provider B = -0.19, SE = 0.06, p = 0.003, 95% CI (-0.309 to -0.062); and Black-Black B = -0.30, SE = 0.14, p =  improve continuum of care outcomes.Syphilis rates have continued to rise in the United States. Florida and Louisiana consistently report high numbers of cases. We evaluated rates of reinfection to see if frequent rescreening might lead to earlier treatment and prevent infections. All syphilis records of all stages for males and females aged 15-70 years from the Florida and Louisiana Departments of Health surveillance databases 2000-2018 were evaluated. The first episode of syphilis during this period was considered the initial diagnosis for each person. Demographics of cases and repeaters (individuals reported with two or more cases of syphilis) were examined. Percentages of syphilis cases from repeaters by year were calculated as were percentages from HIV+ males. During 2000-2018, 124,827 syphilis cases were reported from 107,405 individuals 73,811 (68.7%) males; 33,594 (31.3%) females. There were 12,545 individuals (repeaters) with two or more syphilis diagnoses (n = 17,422 cases; range, 2-10). From 2010 to 2018, repeaters accounted for steadily increasing percentage of all syphilis reported 2010 (11%), 2013 (16%), 2015 (20%), and 2018 (26%). Among HIV+ male cases the percentage from repeaters also increased 2010 (28%), 2013 (35%), 2015 (42%), and 2018 (50%). In 2018, 19% of all cases (n = 2455) were from HIV+ males who had a previous syphilis diagnosis. Among HIV+ males diagnosed with syphilis in 2015, 34% had a repeat syphilis diagnosis within 3 years. Most syphilis diagnosed in Florida and Louisiana was among persons infected for the first time. However, some subgroups could possibly benefit from more frequent screening. Males living with HIV who had a prior syphilis diagnosis were at very high risk of repeat infection.Daily antiretroviral therapy (ART) suppresses viral replication, rendering HIV undetectable through viral load (VL) testing. People living with HIV (PLWH) who have an undetectable VL cannot transmit HIV to sexual partners or through giving birth, a message commonly referred to as U = U (undetectable equals untransmittable). To increase knowledge and understanding of U = U among men, who have poorer HIV testing and treatment outcomes than women, we engaged men from high HIV burden communities in Cape Town in two interactive human-centered design cocreation workshops to develop local U = U messaging for men. Two trained workshop facilitators, explained the U = U message to 39 adult men (in two separate workshops), and asked them how to effectively communicate U = U to other men in the local language (isiXhosa). Participant-designed messages sought to inform men about U = U to help assuage fears of testing HIV positive (by removing the stigma of living with HIV and being a vector of disease), and to explain that ART enables PLWH to live normal healthy lives, making HIV "untransmittable" to sex partners. Participants' messages emphasized that when virally suppressed, "I cannot spread HIV to the other person" and "(the pill) keeps on killing the virus so I can live a normal life for the rest of my life." Men cocreated simple local U = U messages to address fears of testing HIV positive and emphasizing ART's positive effects. Cocreated tailored messaging may reduce stigma associated with living with HIV and improve the uptake of HIV testing and treatment among South African men. This study was registered at clinicaltrials.gov under NCT04364165.Stress granules are dynamic, reversible condensates composed of RNA and protein that assemble in eukaryotic cells in response to a variety of stressors and are normally disassembled after stress is removed. The composition and assembly of stress granules is well understood, but little is known about the mechanisms that govern disassembly. Impaired disassembly has been implicated in some diseases including amyotrophic lateral sclerosis, frontotemporal dementia, and multisystem proteinopathy. Using cultured human cells, we found that stress granule disassembly was context-dependent Specifically in the setting of heat shock, disassembly required ubiquitination of G3BP1, the central protein within the stress granule RNA-protein network. We found that ubiquitinated G3BP1 interacted with the endoplasmic reticulum–associated protein FAF2, which engaged the ubiquitin-dependent segregase p97/VCP (valosin-containing protein). Thus, targeting of G3BP1 weakened the stress granule–specific interaction network, resulting in granule disassembly.Purpose This purpose of this study was to assess the frequency and types of phonological process errors in patients with velopharyngeal dysfunction (VPD) and the different types of palatal anomalies. Method A total of 808 nonsyndromic patients with VPD, who underwent follow-up at the Center for Cleft Palate and Craniofacial Anomalies, from 2000 to 2016 were included. Patients were stratified into four age groups and five subphenotypes of palatal anomalies cleft lip and palate (CLP), cleft palate (CP), submucous cleft palate (SMCP), occult submucous cleft palate (OSMCP), and non-CP. Phonological processes were compared among groups. Results The 808 patients ranged in age from 3 to 29 years, and 439 (54.3%) were male. Overall, 262/808 patients (32.4%) had phonological process errors; 80 (59.7%) ages 3-4 years, 98 (40, 0%) ages 4.1-6 years, 48 (24.7%) 6.1-9 years, and 36 (15.3%) 9.1-29 years. Devoicing was the most prevalent phonological process error, found in 97 patients (12%), followed by cluster reduction in 82 (10.1%), fronting in 66 (8.2%), stopping in 45 (5.6%), final consonant deletion in 43 (5.3%), backing in 30 (3.7%), and syllable deletion and onset deletion in 13 (1.6%) patients. No differences were found in devoicing errors between palatal anomalies, even with increasing age. Phonological processes were found in 61/138 (44.20%) with CP, 46/118 (38.1%) with SMCP, 61/188 (32.4%) with non-CP, 70/268 (26.1%) with OSMCP, and 25/96 (26.2%) with CLP. Phonological process errors were most frequent with CP and least with OSMCP (p = .001). Conclusions Phonological process errors in nonsyndromic VPD patients remained relatively high in all age groups up to adulthood, regardless of the type of palatal anomaly. Our findings regarding the phonological skills of patients with palatal anomalies can help clarify the etiology of speech and sound disorders in VPD patients, and contribute to general phonetic and phonological studies.Pectobacterium spp. and Dickeya spp. cause Blackleg on potato worldwide (Charkowski, 2018). Potato plants (cv. Selleck CHIR-99021 Innovator V4 or Favorita) with blackleg symptoms (vascular browning of crown stems or curled leaves, Fig. S1) were observed in the field in Xilingol League, Inner Mongolia in 2018, and in Chengdu, Sichuan Province in 2020, in China. The disease incidence were around 10% and 20% in Xilingol League (20 ha) and Chengdu (40 ha), respectively. link2 Diseased plants (5 from Xilingol League, and 2 from Chengdu) were collected to isolate the pathogen. Blackleg symptomatic stems were soaked in 75% ethanol for 2 min, rinsed and ground in sterile distilled water. Serial tenfold dilutions of the above solution were plated onto the crystal violet pectate agar (CVP) plate (Ge et al., 2018). Two to 3 days after incubation at 28°C, the bacterial colonies which digested pectin from the media and developed pit on CVP plates were purified and sequenced for identification using the universal 16S rRNA gene primer set 27F/1492R 80% humidity and 21°C for 2 days. Seven days after inoculation, the infected area of the inoculated seedlings rotten and turned black or even lodged, while the controls were symptomless (Fig. S4). It was observed that isolate MZ489432 from Chengdu, Sichuan Province was more virulent than the isolates from Xilingol League (Fig. S4). Bacterial colonies were reisolated from these symptomatic seedlings and identified using the same methods described above. link3 Blackleg on potato plants has been reported to be caused by Pectobacterium atrosepticum, Pectobacterium carotovorum subsp. carotovorum, Pectobacterium carotovorum subsp. brasiliense, and Pectobacterium parmentieri in China (Zhao et al., 2018; Cao et al., 2021). To our knowledge, this is the first report of blackleg of potato caused by Pectobacterium polaris in China. We believe that this report will draw attention to the management of this pathogen in China.
