RESUMO

Pesticide loads and associated toxicity can be significantly reduced using integrated vegetated treatment systems, which remove moderately soluble and hydrophobic pesticides, but need a sorbent material to remove more soluble pesticides. Neonicotinoids such as imidacloprid are widely used insecticides, acutely toxic, and have been linked to a range of ecological effects. Laboratory experiments were conducted to test the sorptive capacity of granulated activated carbon and biochar for removing imidacloprid and the organophosphate insecticide chlorpyrifos in a scaled-down treatment system. Simulated irrigation water spiked with individual pesticides was treated with a bench-top system designed to mimic a 600 L carbon installation receiving 108,000 L of flow per day for sixteen days. Biochar reduced insecticides to less than detectable and non-toxic levels. Granulated activated carbon similarly reduced chlorpyrifos, but allowed increasing concentrations of imidacloprid to break through. Both media treated environmentally relevant concentrations, and would be effective if used under conditions with reduced particle loads.

RESUMO

Endometriosis, a systemic ailment, profoundly affects various aspects of life, often eluding detection for over a decade. This leads to enduring issues such as chronic pain, infertility, emotional strain, and potential organ dysfunction. The prolonged absence of diagnosis can contribute to unexplained obstetric challenges and fertility issues, necessitating costly and emotionally taxing treatments. While biopsy remains the gold standard for diagnosis, emerging noninvasive screening methods are gaining prominence. These tests can indicate endometriosis in cases of unexplained infertility, offering valuable insights to patients and physicians managing both obstetric and non-obstetric conditions. In a retrospective cross-sectional study involving 215 patients aged 25 to 45 with unexplained infertility, diagnostic laparoscopy was performed after unsuccessful reproductive technology attempts. Pathology results revealed tissue abnormalities in 98.6% of patients, with 90.7% showing endometriosis, confirmed by the presence of endometrial-like glands and stroma. The study underscores the potential role of endometriosis in unexplained infertility cases. Although the study acknowledges selection bias, a higher than previously reported prevalence suggests evaluating endometriosis in patients who have not responded to previous reproductive interventions may be justified. Early detection holds significance due to associations with ovarian cancer, prolonged fertility drug use, pregnancy complications, and elevated post-delivery stroke risk.

RESUMO

INTRODUCTION: We performed a validation study at our institution, the International Union Against Cancer (Union for International Cancer Control latest version of TNM Classification of Malignant Tumors Eighth Edition). METHODS: Data were collected from the Queensland Oncology Online registry of NSCLC or SCLC cases between 2000 and 2015 and validated against the Queensland Integrated Lung Cancer Outcomes Project registry using case identification number, first name, last name, and date of birth. Where data were available, cases were classified according to the Union for International Cancer Control TNM seventh edition stage groupings and then compared with the eighth edition groupings. Kaplan-Meier curves were plotted, and the log-rank test of survival differences was performed with SPSS version 25 (IBM Corp, Armonk, NY). RESULTS: Of the 3636 cases, 3352 and 1031 had complete clinical and pathologic staging, respectively. Median survival time was found to reduce with increasing clinical stage: seventh edition (IA: 88, IB: 44, IIA: 31, IIB: 18, IIIA: 15, IIIB: 8, and IV: 5 mo) versus eighth edition TNM stage (IA1: not reached, IA2: 88, IA3: 53, IB: 56, IIA: 36, IIB: 22, IIIA: 14, IIIB: 9, IIIC: 8, IVA: 6, and IVB: 3 mo). A similar overall pattern was reflected in the pathologic stage: seventh edition (IA: 124, IB: 110, IIA: 48, IIB: 42, IIIA: 26, IIIB: 31, and IV: 27 mo) versus eighth edition (IA1: not reached, IA2: 122, IA3: 125, IB: 144, IIA: 98, IIB: 57, IIIA: 31, IIIB: 24, and IVA: 7 mo). The log-rank test for survival curves was significant at p < 0.001. CONCLUSIONS: Our external validation study confirms the prognostic accuracy of the eighth edition TNM lung cancer classification. Our analyses also indicated that IIIB, IIIC, and IVA stage groups had similar survival outcomes and suggest further research for refinement.

RESUMO

Cell fate specification in the early C. elegans embryo requires the activity of a family of proteins with CCCH zinc-finger motifs. Two members of the family, MEX-5 and MEX-6, are enriched in the anterior of the early embryo where they inhibit the accumulation of posterior proteins. Embryos from mex-5 single-mutant mothers are inviable due to the misexpression of SKN-1, a transcription factor that can specify mesoderm and endoderm. The aberrant expression of SKN-1 causes a loss of hypodermal and neuronal tissue and an excess of pharyngeal muscle, a Mex phenotype (muscle excess). POS-1, a third protein with CCCH motifs, is concentrated in the posterior of the embryo where it restricts the expression of at least one protein to the anterior. We discovered that reducing the dosage of pos-1(+) can suppress the Mex phenotype of mex-5(-) embryos and that POS-1 binds the 3'-UTR of mex-6. We propose that the suppression of the Mex phenotype by reducing pos-1(+) is due to decreased repression of mex-6 translation. Our detailed analyses of these protein functions reveal complex interactions among the CCCH finger proteins and suggest that their complementary expression patterns might be refined by antagonistic interactions among them.

RESUMO

This study examines the relationships between adult attachment orientations and the ability to seek social support as factors in mediating behavior. Data were collected on non violent offenders (n = 57) and college students (n = 89). The results indicated the non-normative group of nonviolent offenders reported being more securely attached and having more satisfaction with their social supports than the normative group of college students. Fewer college students reported being securely attached than the nonviolent offenders but had a larger number of social supports. In the insecure categories, nonviolent offenders reported being more dismissively attached whereas college students reported being preoccupied in their attachment orientation. The study suggests that attachment and social-support-seeking behaviors across different populations may be potential factors in designing counseling services that are used for risk classification and needs assessment.

RESUMO

Atopic eczema is a chronic inflammatory condition affecting mainly children and is one of the most common skin disorders in the Western world. It has a strong genetic component associated with atopic conditions such as asthma, hayfever or urticaria. The onset is usually within the first year of life and it affects mainly the face, after which the pattern often changes to involvement of the flexures. The most prominent characteristic of atopic eczema is pruritus (itch) together with dry skin. An important treatment of atopic eczema is the application of emollients (moisturizers) to rehydrate and restore the barrier function of the skin. Wet wrapping using large quantities of emollients is a well recognized therapy for atopic eczema and other dry skin conditions. The introduction of new Tubifast Garments by Medlock Medical makes this topical therapy easy to apply for parents and carers in the management of children's eczema.

RESUMO

INTRODUCTION: The purpose of this study was to explore the factors influencing the implementation or the lack of implementation of advanced practitioner role in Australia. METHODS: This study uses an interpretative phenomenological approach to explore the in-depth real life issues, which surround the advanced practitioner as a solution to radiologist workforce shortages in Australia. Research participants are radiographers, radiation therapists and health managers registered with the Australian Institute of Radiography (AIR) and holding senior professional and AIR Board positions with knowledge of current advanced practice. RESULTS: In total, seven interviews were conducted revealing education, governance, technical, people issues, change management, government, costs and timing as critical factors influencing advanced practice in Australia. CONCLUSIONS: Seven participants in this study perceived an advanced practice role might have major benefits and a positive impact on the immediate and long-term management of patients. Another finding is the greater respect and appreciation of each other's roles and expertise within the multidisciplinary healthcare team. Engagement is required of the critical stakeholders that have been identified as 'blockers' (radiologists, health departments) as well as identified allies (e.g. emergency clinicians, supportive radiologists, patient advocacy groups). The research supports that the AIR has a role to play for the professional identity of radiographers and shaping the advanced practice role in Australia.

RESUMO

The nursing service is a significant element in the dermatological capacity to respond to skin care and dermatological needs worldwide. Although it is an area of development often neglected by dermatologists, it is one that is undergoing rapid and substantial evolution. This paper outlines the initiatives undertaken by nurses to enhance their contribution, and examines the development of nursing within the dermatology field. It argues for the need to develop a service delivery model in dermatology care that utilizes specialist-nursing expertise to cascade dermatological knowledge and skill through primary care. The paper summarizes the strategic importance of nursing in dermatology care delivery, whether in resource-rich or -poor countries, and its unmet potential in the capacity to benefit and meet skin care and dermatological care needs. The paper specifically focuses on the development work led by the International Skin Care Nursing Group (ISNG) to stimulate and develop the capacity of nursing to respond to these widespread needs through promoting service delivery models that operate interdependently with dermatologist-led care.

RESUMO

Anteroposterior polarity in early C. elegans embryos is required for the specification of somatic and germline lineages, and is initiated by a sperm-induced reorganization of the cortical cytoskeleton and PAR polarity proteins. Through mechanisms that are not understood, the kinases PAR-1 and PAR-4, and other PAR proteins cause the cytoplasmic zinc finger protein MEX-5 to accumulate asymmetrically in the anterior half of the one-cell embryo. We show that MEX-5 asymmetry requires neither vectorial transport to the anterior, nor protein degradation in the posterior. MEX-5 has a restricted mobility before fertilization and in the anterior of one-cell embryos. However, MEX-5 mobility in the posterior increases as asymmetry develops, presumably allowing accumulation in the anterior. The MEX-5 zinc fingers and a small, C-terminal domain are essential for asymmetry; the zinc fingers restrict MEX-5 mobility, and the C-terminal domain is required for the increase in posterior mobility. We show that a crucial residue in the C-terminus, Ser 458, is phosphorylated in vivo. PAR-1 and PAR-4 kinase activities are required for the phosphorylation of S458, providing a link between PAR polarity proteins and the cytoplasmic asymmetry of MEX-5.

RESUMO

During early divisions of the C. elegans embryo, many maternally supplied determinants accumulate asymmetrically, and this asymmetry is crucial for proper cell fate specification. SKN-1, a transcription factor whose message is maternally supplied to the embryo, specifies the mesendodermal cell fate. In the 2-cell embryo, SKN-1 is expressed at a higher level in the posterior cell. This asymmetry becomes more pronounced at the 4-cell stage, when SKN-1 is high in the posterior cell's daughters and low in the daughters of the anterior blastomere. To date, the direct mechanisms that control SKN-1 distribution remain unknown. In this report, we identify eel-1, which encodes a putative Hect E3 ubiquitin ligase that shares several domains of similarity to the mammalian E3 ligase Mule. EEL-1 binds SKN-1 and appears to target SKN-1 for degradation. EEL-1 has two functions in regulating SKN-1 during early embryogenesis. First, eel-1 promotes the spatial asymmetry of SKN-1 accumulation at the 2- and 4-cell stages. Second, eel-1 acts in all cells to downregulate SKN-1 from the 12- to the 28-cell stage. Although loss of eel-1 alone causes a reduction in SKN-1 asymmetry at the 2-cell stage, the function of eel-1 in both the spatial and temporal regulation of SKN-1 is redundant with the activities of other genes. These data strongly suggest that multiple, functionally redundant pathways cooperate to ensure precise control of SKN-1 asymmetry and persistence in the early embryo.

RESUMO

The principles and techniques of natural balance trimming and shoeing are designed to optimize the efficiency and function of the foot. The basic guidelines have evolved in part from wild horse hoof imprint studies done in 1986 through 1987 and first presented in 1995. Further research has contributed to these principles and guidelines to make them applicable to domestic horses.
