Article Synopsis
  • Cyanate, a harmful byproduct from cyanide oxidation, can be safely turned into ammonia and carbon dioxide using an enzyme called cyanase, which was improved for stability and reusability by trapping it in biomimetic silica.
  • The entrapped cyanase exhibited double the enzyme activity and maintained better performance at elevated temperatures and after a month at room temperature compared to the free enzyme.
  • By co-entrapping another enzyme, carbonic anhydrase, the process for detoxifying cyanate was made more efficient, requiring less bicarbonate and maintaining significant effectiveness even after five reuse cycles.

Hematopoietic stem cell (HSC) transplantation, using either bone marrow (BM) or peripheral blood stem cells (PBSC), is a well-established therapy for various hematologic and non-hematologic diseases. However, the long-term health outcomes after HSC donation remain a major concern for several potential donors. Thus, we aimed to conduct a matched cohort study of 5003 unrelated donors (1099 BM and 3904 PBSC) and randomly selected 50,030 matched controls based on age, sex, and resident area from the donor registry between 1998 and 2018.

Background: Spontaneous intracerebral hemorrhage (ICH) is a condition associated with high mortality and morbidity. Survivors may require prolonged intubation with mechanical ventilation (MV). The aim of this study was to analyze the predictors of extubation failure and prolonged MV in patients who undergo surgical evacuation.

Background: Atopic dermatitis (AD) is rising globally, with genetics and environmental factors both playing crucial roles. Dietary habits during pregnancy are linked to children's allergic disease risk. However, limited studies have explored the association between maternal vegetarian diets during pregnancy and child AD.

Background: The optimum approach to enhance the understanding toward dementia is to experience how patients feel as they experience the manifestations of the disease. The application of virtual reality (VR) and relevant innovative technologies for developing caregiver training programs allows caregivers to better understand dementia and empathize with patients.

Objectives: To develop a VR-based experiential training course on individualized care for the behavioral and psychological symptoms of dementia (BPSD).

The reaction condition for purifying carbonic anhydrase from (SspCA) by direct heating without prior cell lysis was optimized; heating at 70 °C for 5 min resulted in the highest total activity of 23,460 WAU (Wilbur-Anderson unit) from a 50 mL culture. Heat-purified SspCA was examined for its capability to increase the rate of the mineralization of CO; compared with an uncatalyzed control, the onset time of CaCO formation was shortened by up to 71%. Cyanase can be used to degrade toxic cyanate; however, one of the limitations of this biomimetic process is that the reaction needs HCO as a substrate.

Phthalates have become a matter of public health concern due to their extensive use worldwide and negative health effects. The evaluation of potential sources of phthalate exposure is crucial to design prevention strategies, especially for vulnerable populations. This study included 528 mother-child pairs in the Taiwan Mother Infant Cohort Study who were followed up at ages 3-6 years between 2016 and 2020.

Article Synopsis
  • The study investigates how frailty in middle-aged and older adults affects their life satisfaction, particularly in relation to physical disability and activity levels.
  • Data from the Taiwan Longitudinal Study in Ageing analyzed the interactions between these factors using different mediation models, emphasizing both parallel and sequential relationships.
  • Results indicated that increased frailty leads to worse physical disability, which negatively impacts physical activity and, consequently, life satisfaction, with age being a significant factor in these relationships.

Background And Objective: The purpose of our study was to explore the immediate and long-term effects of socially assistive robots (SARs) on neuropsychiatric symptoms (NPSs), behavioral and psychological symptoms of dementia (BPSD), positive emotional experiences, and social interaction in older people living with dementia.

Methods: We set keywords and used Boolean operators to search the CINAHL, Cochrane Library, EMBASE, IEEE Digital Library, MEDLINE, PsycINFO, PubMed, Web of Science, Scopus, and Chinese Electronic Periodical Service from inception to February 2022 for randomized controlled trials. The Cochrane Collaboration bias assessment tool was used to assess article quality, and RevMan 5.

Resource recycling has become an integral part of environmental protection efforts. At present, the development of Taiwan's resource recovery and related works are quite mature. However, laborers or volunteers working in resource recycling stations may be exposed to different types of hazards during the recycling process.

Background/purpose: This study aims to establish reference intervals for important biochemical parameters in cord blood of newborn male and female infants in Taiwan and to investigate their sex difference. We also examined the correlation of the same markers between maternal blood levels and neonatal cord blood levels.

Methods: 2,136 pregnant women receiving regular routine prenatal health assessments in their third trimester (weeks 29-40) were recruited from nine hospitals in Taiwan between 2012 and 2015.

Previous studies have shown associations between prenatal phthalate exposure and neurobehavioral changes in children. However, few studies have focused on neonatal neurobehavioral development. This study aimed to examine the associations between prenatal phthalate exposure and neonatal neurobehavioral development in the early days of life after birth.

Background: Frailty refers to a decline in an elderly person's physical, psychological, and social functioning, making them sensitive to stressors. Because frailty is caused by a variety of factors, including certain demographic characteristics, understanding the mediating factors that affect frailty in the elderly is critical.

Purpose: To provide evidence about the relationship between depression, well-being, social activity, physical performance, and frailty among older adults.

Background: Cerebrospinal fluid (CSF) venous fistulas are a recently discovered and underdiagnosed cause of spontaneous spinal CSF leak, which may lead to spontaneous intracranial hypotension. Most cases occur in the thoracic spine, and only 2 cases were reported in the cervical spine. Treatments include the epidural blood patch, fibrin glue injection, and surgical ligation of the fistula.

Environmental exposures to mixtures of toxic chemicals have potential interaction effects that may lead to hazard index values exceeding one. However, current regulation levels, such as tolerable daily intake (TDI), are mostly based on experimental studies conducted with a single chemical compound. In this study, we assessed the relationships between melamine and di-(2-ethylhexyl) phthalate (DEHP) exposure and their coexposure with the early renal injury markers N-acetyl -D-glucosaminidase (NAG), albumin/creatinine ratio (ACR), and microalbuminuria in 1236 pregnant women.

Background: Phthalates are widely used in consumer products, food packaging, and personal care products, so exposure is widespread. Several studies have investigated the association of phthalate exposure with obesity, insulin resistance, and hypertension. However, little is known about the associations of phthalate exposure with sex, age, and menopausal status in metabolic syndrome (MetS).

Tissue wounding induces cutaneous sensory axon regeneration via hydrogen peroxide (HO) that is produced by the epithelial NADPH oxidase, Duox1. Sciatic nerve injury instead induces axon regeneration through neuronal uptake of the NADPH oxidase, Nox2, from macrophages. We therefore reasoned that the tissue environment in which axons are damaged stimulates distinct regenerative mechanisms.

Background: Exposure to either melamine or phthalate, two common toxicants, during pregnancy may cause adverse health effects, including kidney damage.

Objectives: We investigated the independent and interactive effect of exposure to melamine and phthalates, particularly di-(2-ethylhexyl) phthalate (DEHP), on markers of early renal injury in women their third trimester of pregnancy in one nationwide birth cohort, the Taiwan Maternal and Infant Cohort Study (TMICS).

Methods: Between October, 2012 and May, 2015, participants were administered questionnaires, physical examinations, and blood and urine tests during their third trimester.
