The contrast humidity sensing experiment compared to the existing commercial humidity sensor further demonstrated the higher and faster response of our WCN-based sensors. Thus, this work provides effective guidance for the design of high-performance humidity sensors using nanopapers and opens a new dimension for a variety of future applications.

Top-down restoration of distorted speech, tapped as phonemic restoration of speech in noise, maybe a useful tool to understand robustness of perception in adverse listening situations. However, the relationship between phonemic restoration and speech perception in noise is not empirically clear.

20 adults (40-55 years) with normal audiometric findings were part of the study. Sentence perception in noise performance was studied with various signal-to-noise ratios (SNRs) to estimate the SNR with 50% score. this website Performance was also measured for sentences interrupted with silence and for those interrupted by speech noise at -10, -5, 0, and 5 dB SNRs. The performance score in the noise interruption condition was subtracted by quiet interruption condition to determine the phonemic restoration magnitude.

Fairly robust improvements in speech intelligibility was found when the sentences were interrupted with speech noise instead of silence. Improvement with increasing noise levels was non-monotonic and reached a maximum at -10 dB SNR. Significant correlation between speech perception in noise performance and phonemic restoration of sentences interrupted with -10 dB SNR speech noise was found.

It is possible that perception of speech in noise is associated with top-down processing of speech, tapped as phonemic restoration of interrupted speech. More research with a larger sample size is indicated since the restoration is affected by the type of speech material and noise used, age, working memory, and linguistic proficiency, and has a large individual variability.

Recurrent auricular hematoma can be a challenging medical problem, with complications resulting in ear deformity, therefore, appropriate management is important. Improper treatment can result in a deformity known as 'cauliflower ear' or 'wrestler's ear.' We report a case of othematoma that was inappropriately treated and present a review of current treatment options.

Globally, the human immunodeficiency virus (HIV) is responsible for one of the most serious pandemics to date. The vulnerability of the vestibular system in individuals with HIV has been confirmed, and central vestibular impairments have been frequently reported. However, there are disagreements on the impact of HIV on peripheral vestibular function. Thus, the current study aimed to determine the prevalence of peripheral vestibular impairment, specifically related to the semi-circular canals (SCCs), in HIV-positive individuals receiving antiretroviral (ARV) treatment.

A total of 92 adults between the ages of 18 and 50 years (divided into two groups) participated in the study. The first group comprised HIV-positive individuals receiving ARV treatment (n1=60), and the second group comprised HIV-negative participants (n2=32). The video head impulse test was used to conduct the head impulse paradigm (HIMP).

Bilateral normal HIMP results were obtained in 95% of the HIV-positive participants and all HIV-negative participants. The gain of the left posterior SCCs was significantly lower in the HIV-positive group, while the gains of all other canals between the two groups were comparable.

The prevalence of peripheral vestibular impairment in the HIV-positive group was not significantly different from that of the HIV-negative group. The reduced prevalence in the current study may be attributed to participant characteristics, the test battery employed, and the central compensation of the vestibular dysfunctions at the later stages of infection.

It participates in the regulation of multiple biological processes, including cell cycle, apoptosis, DNA repair, antigen presentation, receptor endocytosis, intracellular signal transduction. Recent studies have found that the ubiquitin-proteasome pathway can participate in the formation and development of hypertrophic scar by regulating transforming growth factor beta/Smad signal transduction and proliferation, differentiation, and apoptosis of fibroblasts. This article summarizes the effects of ubiquitin ligase enzyme, proteasome, and deubiquitinating enzyme in ubiquitin-proteasome pathway in hypertrophic scar, in order to provide new idea for the prevention and treatment of hypertrophic scar.Chronic refractory wound refers to the wound with unclear etiology, multiple and complex injury factors, slow healing, and no obvious tendency of healing after treatment for 4 weeks. The formation and evolution process of chronic refractory wounds are very complex, involving re-epithelialization of wound tissue, cell proliferation, tissue remodeling, and angiogenesis and lymphangiogenesis. The abnormal expression of long non-coding RNA may be involved in the formation of chronic refractory wounds, but the specific pathogenesis and related molecular biological changes are still controversial. In this paper, we reviewed the process and role of long non-coding RNA in regulating keratinocyte differentiation, fibroblast proliferation, and regeneration of vascular and lymphatic endothelial cell in chronic refractory wounds.With the aggravation of aging of global population and increase of incidence of various chronic diseases and injuries, patients with chronic wounds due to different causes (malnutrition, abnormal metabolism, compression, infection, tumor, etc.) have grown. Especially in some patients at the end of life, chronic wounds have the characteristics of difficult to heal and even unable to heal. There is an urgent need for palliative treatment for such wounds. Palliative treatment of chronic wounds focuses on the management of smell, pain, exudate, bleeding, and infection with the hope to effectively prevent infection, relief pain, improve quality of life, and reduce the economic burden of medical treatment for patients. This paper reviews the related studies of palliative treatment in chronic wounds at home and abroad, and explores the evaluation and management of palliative treatment of different wounds with the aim to provide new management strategies, new materials, and new concept for the treatment of chronic wounds.The maintenance of posture and anti-contracture treatment are the critical elements of comprehensive burn rehabilitation in the overall treatment period of pediatric burns. Although domestic experts in burn discipline have formulated guidelines for burn rehabilitation, the maintenance of posture and design and manufacture of splints for anti-scar contractures in children with burns are different from that for adults with burns in many ways. Starting with paying the attention to the rehabilitation problems in pediatric burns, especially considering the anatomical, psychological, and social behavior characteristics of children in developmental period, the author's team effectively applies splints to maximize the prevention of contractures in children and maintain and improve the range of their joint movements. The splints designed to prevent contractures in pediatric burns shall fit the small limb and meet their expected goals of rehabilitation. In each aspect of the production and use of splints, it is necessary to fully evaluate and consider the scar characteristics, growth and development status, activity level, and compliance of children, and adaptability and fixation methods of the splints, so as to select the appropriate splint type and formulate the wearing plan.A 58-year-old male patient with diabetic foot ulcer was admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine on December 11, 2018. The patient was treated with local debridement, vacuum sealing drainage treatment, and dressing change and discharged after basic wound healing. On January 15, 2019, the patient was hospitalized again due to local infection and rupture of wound surface. He underwent a surgical debridement on the third day after second admission and was given intravenous infusion of 0.4 g teicoplanin twice daily. Histopathological examination after surgery showed keratinizing squamous-cell carcinoma. An extended squamous-cell carcinoma resection plus autologous split-thickness skin grafting and vacuum sealing drainage treatment was carried out on the 10th day after second admission. The patient's whole body turned red after surgery with rash, recurrent fever over 39 ℃, leucopenia, and thrombocytopenia. A multi-disciplinary consultation of physicians attributed these symptoms to teicoplanin-induced hypersensitivity syndrome. After withdrawal of teicoplanin and administration of hormone, the patient's temperature returned to normal, and the leucocyte count and platelet count recovered gradually. The patient was cured and discharged on the 49th day after second admission. The case presented reminds us of need to strictly follow the indications of teicoplanin prior to medication, be resolute to the administration and withdrawal, and be alert to adverse drug reactions when above-mentioned abnormalities occur, meanwhile, infection and rheumatic diseases are excluded.On April 26, 2018, a 55-year-old male patient with severe phenol burn complicated with acute poisoning was admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine. The patient quickly developed the symptoms of central nervous system including blurred consciousness and restlessness, anuria, and respiratory failure. After self-rescue before admission and a series of measures in hospital including wound decontamination to reduce phenol absorption, rapid massive infusion and hemodialysis+ hemoperfusion, continuous renal replacement therapy for speeding up phenol excretion and organ function maintenance, the poisoning symptoms were effectively alleviated, and the patient was finally rescued successfully and discharged on post injury day 29. This case suggests that early hemodialysis combined with hemoperfusion and continuous renal replacement therapy are effective methods for treating severe phenol burn complicated with acute poisoning.
