Demographic and clinical findings of patients with mucocutaneous morphea have not been well characterized.

To determine the demographic and clinical characteristics of morphea patients with mucocutaneous lesions enrolled in the Morphea in Adults and Children Cohort (MAC).

Cross-sectional study of 735 patients in the MAC Cohort from 2007 to 2018.

4.6% of linear morphea patients had oral involvement versus 2.4% among the entire cohort while 10.3% of generalized morphea patients had genital involvement versus 3.7% among the entire cohort. Those with genital lesions had an older age of disease onset than oral morphea (57 versus 11.5 years old; p<0.001) and more frequent extragenital lichen sclerosus atrophicus (LSA) (59.2% versus 5.6%; p=0.004).

Selection bias and limited number of affected subjects.

Oral morphea lesions predominate in younger patients with facial linear morphea while genital lesions predominate in post-menopausal women with overlying extragenital LSA.

However, the toxicity of Bt proteins against yellow peach moth (YPM), Conogethes punctiferalis (Guenée), one of the most serious maize pests in China, has not received much study. Therefore, we performed diet-overlay bioassays to evaluate the insecticidal activities of Cry1Ab, Cry1Ac, Cry1Fa, Cry1Ah, Cry1Ie, Cry2Aa, and Vip3Aa19, as well as the interaction between Cry1-Class, Cry2Aa, and Vip3Aa19 against YPM. Results showed that the LC50 values ranged from 1.08 to 178.12 ng/cm2 (protein/diet). Among these proteins, Cry1Ab and Cry1Ac had lower LC50 values and LC90 values. In YPM bioassays, the combinations of Cry2Aa with Cry1Ac, Cry1Ie, and Cry1Ab showed antagonism while a mixture of Cry2Aa with Cry1Fa and Cry1Ah exhibited synergism. When Vip3Aa19 was combined with Cry proteins, all combinations interacted positively, with variation in synergistic factors (SF). Three ratios 11, 12, and 21 of Cry1Ah and Vip3Aa19 protein combination showed SF values of 5.20, 5.63, and 8.98, respectively. These findings can be applied in the establishment of new pyramided transgenic crops with suitable candidates as well as in resistance management strategies.The OneHealth approach aims to further our understanding of the drivers of human, animal and environmental health, and, ultimately, to improve them by combining approaches and knowledge from medicine, biology and fields beyond. click here Wild and managed bees are essential pollinators of crops and wild flowers. Their health thus directly impacts on human and environmental health. At the same time, these bee species represent highly amenable and relevant model organisms for a OneHealth approach that aims to study fundamental epidemiological questions. In this review, we focus on how infectious diseases of wild and managed bees can be used as a OneHealth model system, informing fundamental questions on ecological immunology and disease transmission, while addressing how this knowledge can be used to tackle the issues facing pollinator health.Fungal keratitis (FK) accounts for approximately half of the microbial keratitis encountered in low middle income countries (LMICs) and predominantly affect the working rural-poor. FK causes significant morbidity with the majority of patients left with moderate or worse visual impairment and approximately 25% requiring expensive and often unsuccessful surgical interventions. The severity of FK and the resultant corneal damage or resolution can be attributed to i) the virulence and bioburden of the fungal pathogen, ii) the host defense mechanism and immune response and iii) sub-optimal diagnostics and anti-fungal treatment strategies. This review provides a comprehensive overview of the multifaceted components that drive FK progression and resolution, highlighting where knowledge gaps exist and areas that warrant further research.The coronavirus disease 2019 (COVID-19) pandemic has created an urgent need for therapeutics that inhibit the SARS-COV-2 virus and suppress the fulminant inflammation characteristic of advanced illness. Here, we describe the anti-COVID-19 potential of PTC299, an orally bioavailable compound that is a potent inhibitor of dihydroorotate dehydrogenase (DHODH), the rate-limiting enzyme of the de novo pyrimidine nucleotide biosynthesis pathway. In tissue culture, PTC299 manifests robust, dose-dependent, and DHODH-dependent inhibition of SARS-COV-2 replication (EC50 range, 2.0-31.6 nM) with a selectivity index >3,800. PTC299 also blocked replication of other RNA viruses, including Ebola virus. Consistent with known DHODH requirements for immunomodulatory cytokine production, PTC299 inhibited the production of interleukin (IL)-6, IL-17A (also called IL-17), IL-17 F, and vascular endothelial growth factor (VEGF) in tissue culture models. The combination of anti-SARS-CoV-2 activity, cytokine inhibitory activity, and previously established favorable pharmacokinetic and human safety profiles render PTC299 a promising therapeutic for COVID-19.
A few studies of Western populations have found inconsistent results regarding the associations between vitamin D status and physical function. We explored the association between circulating vitamin D status [plasma 25-hydroxyvitamin D, 25(OH)D] and incident activities of daily living (ADL) disability among Chinese older adults.

Community-based longitudinal cohort study.

A total of 2453 men and women (median age 84.0years) in 7 Chinese longevity areas were included.

Cox proportional hazards regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for incident ADL, with adjustments for potential sociodemographic, and lifestyle confounders and biomarkers. Because there was a statistically significant interaction between plasma 25(OH)D and sex in relation to incident ADL, men and women were analyzed separately.

The median concentrations of plasma 25(OH)D were 46.6nmol/L and 36.4nmol/L for men and women, respectively. Compared with the lowest quartile in the fully adjusted model, the HR for incident ADL disability for the highest quartile was 0.
