Lin Wang, Bradley P Owens, Junchao Jason Li, Lihua Shi
In this article, the authors further develop the theory of leader humility by exploring the affective impact, a vital boundary condition, and the antecedents of leader humility. Specifically, they (a) theorize how leader humility can enhance followers' performance by increasing their relational energy and decreasing their emotional exhaustion, (b) test perceived leader power in the organization as an important boundary condition of leader humility effectiveness, and (c) establish leader's incremental theory of the self (i...

The health influence of air pollution has been an international public health concern. Increasing evidence has suggested that air pollution has been associated with decreased sperm quality. However, the underlying molecular mechanisms are still not fully elucidated. We aimed to verify whether gasoline exhaust leads to reproductive impairment by injuring spermatogonial stem cells and explore its underlying molecular mechanism. Twenty male Sprague-Dawley rats were randomly divided into two groups: the exposure group (n = 10) and the control group (n = 10)...

BACKGROUND: Accurate diagnosis of interstitial lung disease (ILD) is necessary to identify the most appropriate management strategy and to inform prognosis. Many patients cannot be provided a confident diagnosis despite an exhaustive search for potential etiologies and review in a multidisciplinary conference; and are consequently labelled with unclassifiable ILD. OBJECTIVE: to systematically review and meta-analyse previous studies reporting on the diagnostic criteria, prevalence, clinical features, and outcome of unclassifiable ILD...

PURPOSE: Progressive physical frailty in older adults is associated with increased risk of falls, disability, institutionalization, and mortality. Although associations between diabetes and frailty have been observed, the impact of diabetes on frailty in older Hispanics is largely unexplored. We examine the association of diabetes on the odds of frailty among older Mexican Americans. METHODS: Using data from the Hispanic Established Population for the Epidemiological Study of the Elderly from 1995 until 2012, frailty was assessed by slow gait, weak hand grip strength, exhaustion, and unexplained weight loss (n = 1327)...

Particulate matters (PMs) emitted by automobile exhaust contribute to a significant fraction of the global PMs. Extractive atmospheric pressure chemical ionization mass spectrometry (EAPCI-MS) was developed to explore the molecular dependence of PMs collected from exhaust gases produced at different vehicle engine speeds. The mass spectral fingerprints of the organic compounds embedded in differentially sized PMs (e.g., 0.22-0.45, 0.45-1.00, 1.00-2.00, 2.00-3.00, 3.00-5.00, and 5.00-10.00μm) generated at different engine speeds (e...

In 2010, an estimated 400 to 500 children died of acute lead poisoning associated with artisanal gold mining in Zamfara, Nigeria. Processing of gold ores containing up to 10% lead within residential compounds put residents, especially children, at the highest risk. Principal routes of exposure were incidental ingestion and inhalation of contaminated soil and dusts. Several Nigerian and international health organizations collaborated to reduce lead exposures through environmental remediation and medical treatment...

Diesel exhaust aerosols (DEAs) can absorb and accumulate toxic metal particulates and bacteria suspended in the atmospheric environment, which impact human health and the environment. The use of acoustic standing waves (ASWs) to aggregate DEA is currently considered to be an efficient particle removal method; however, study of the effect of different temperatures on the acoustic aggregation process is scarce. To explore the method and technology to regulate and optimize the aerosol aggregation process through temperature tuning, an acoustic apparatus integrated with a temperature regulation function was constructed...

Stress renders an individual to experience mental pressure and exhaustion which brings about feelings of anxiety, depression, anger and/or other negative emotions. Depression affects a person's state of mind, behaviour, health and is often associated with suicide. The use of anti-depressant drugs as therapeutic agents is associated with symptoms such as, delayed onset of action, side-effects, drug-drug and dietary interactions, sexual dysfunction, cardiac toxicity, etc. Thus, there is need to target these issues and improve current treatment options...

Miriam Turiel Miranda, Pau Agulles Simó
The levonorgestrel-releasing intrauterine device known as Mirena IUD(r) (20mcg/24h) is nowadays considered among the leading resources in the treatment of heavy menstrual bleeding. Nonetheless, due to either its effect of prevention of conception and especially to the possibility that it may also have an anti-implantation effect, there is a founded concern on whether its therapeutic use may be ethically licit. This article engages in an exhaustive literature review in order to ascertain the mechanism of action of Mirena(r) IUD, in view of an ethical evaluation of its therapeutic use, keeping in mind those two unwanted effects...

There is growing interest in developing non-pharmacological treatments that could boost natural defenses against cancer and contribute to primary and secondary cancer prevention. Recent studies have shown that gentle daily stretching for 10 minutes can reduce local connective tissue inflammation and fibrosis. Because mechanical factors within the stroma can influence the tumor microenvironment, we hypothesized that stretching would reduce the growth of tumors implanted within locally stretched tissues and tested this hypothesis in a mouse orthotopic breast cancer model...

Small cell lung cancer (SCLC) represents the most aggressive pulmonary neoplasm and is often diagnosed at late stage with limited survival, despite combined chemotherapies. We show in an autochthonous mouse model of SCLC that combined anti-VEGF/anti-PD-L1 targeted therapy synergistically improves treatment outcome compared to anti-PD-L1 and anti-VEGF monotherapy. Mice treated with anti-PD-L1 alone relapsed after 3 weeks and were associated with a tumor-associated PD-1/TIM-3 double positive exhausted T cell phenotype...

INTRODUCTION: Assisted Reproductive Technologies (ART) is increasingly used to help infertile couples to have children around the world. A number of studies have been published reporting an increased risk of major malformations in children born following ART, especially an increased incidence of epigenetic diseases (ED). This study aimed to assess the incidence of epigenetic diseases with affected imprinting genes in infants or children from pregnancies obtained through IVF/ICSI compared to infants or children from pregnancies obtained spontaneously...

Artichoke by-products are a suitable source of health-promoting ingredients for the production of dietary supplements and food additives. A pressurized hot water extraction (PHWE) was developed to recover caffeoylquinic acids (CQAs) and flavone glycosides (FLs) from agro-industrial artichoke by-products. The main factors influencing PHWE efficiency and CQA isomerization (temperature, numbers of cycles, modifier and extraction time) were carefully studied and optimized by response surface design. The proposed PHWE procedure provides an exhaustive extraction of CQAs and FLs (recoveries: 93-105 and 90-105%) from artichoke external bracts and leaves of different cultivars (p > 0...

A number of studies have found that control over work conditions and hours is positively related to mental health. Still, potential positive and negative effects of work flexibility remain to be fully explored. On the one hand, higher work flexibility might provide better opportunities for recovery. On the other hand, especially mothers may use flexibility to meet household and family demands. Here, we investigated the association between parent's work flexibility, rated relative to their partner, and emotional exhaustion in interaction with gender...

Research has not focused on the negative effects of despotic leadership on subordinates' life satisfaction and the interface between work and family. Drawing on the Conservation of Resources theory, this research investigates the mediating effect of emotional exhaustion through which despotic leadership transcends from the workplace to subordinates' personal lives, resulting in work-family conflict and decreased life satisfaction. The research also examines the moderating effect of subordinates' anxiety on the relationship of their perceptions of despotic leadership with work-family conflict and life satisfaction...
