Purpose: The purpose of this study was to examine the paternal stress and nursing support as perceived by fathers of high risk infants admitted to Neonatal Intensive Care Units (NICU). Methods: The study participants included 88 fathers of high risk infants in NICUs. Their parental stress and nursing support were measured using a self-report questionnaire. Results: The parental stress level of the fathers was 3.57 of a possible 5. Among the parental stress items, 'Relationship with infant and parental role' had the highest scores. The perceived nursing support level was a relatively high, 3.90 on a 5-point scale. The lowest score was for the item 'showed concern about my well-being.' The parental stress was lower in fathers with low income, higher in fathers in nuclear families and when the infants' condition was serious. Conclusion: The findings indicate that fathers of high risk infants experience intense parental stress. Thus when designing care to provide support for these fathers and their infants, it is necessary to encourage the fathers' engagement, provide information on how to respond to the baby, and include supportive care to the fathers.

Sensitive issues are both common and problematic for health care providers because sensitive issues may interfere with the future provider-client relationship and effective care. Most current training for providers focuses on a particular issue, but this is inadequate because many issues may be sensitive, and which issues will be sensitive is unpredictable. We argue that issues become sensitive when they activate one or more of three common triggers, fear, stigma, and taboo. A cycle of negative internal and interpersonal responses to the sensitive issue often leads to unresolved health issues for clients and stress and feelings of inadequacy for providers. We recommend integrated pre-service and in-service skill building to help individual health care providers respond appropriately to a wide variety of sensitive issues. We also identify specific policies and procedures to strengthen organizational support for caregivers so that providers can address these sensitive issues effectively with their clients.

Candida albicans is a major pathogenic fungus in humans, and meets at first the innate immune cells, such as macrophages, in its host. One important strategy of the host cell to kill C. albicans is to produce reactive oxygen species (ROS) by the macrophages. In response to ROS produced by the macrophages, C. albicans operates its defense mechanisms against them by expressing its oxidative stress response genes. Although there have been many research studies explaining the specific transcription factors and the expression of the oxidative stress genes in C. albicans, the regulation of the oxidative stress genes by chromatin structure is little known. Epigenetic regulation by the chromatin structure is very important for the regulation of eukaryotic gene expression, including the chromatin structure dynamics by histone modifications. Among various histone modifications, histone acetylation is reported for its direct relationship to the regulation of gene expression. Recent studies reported that histone acetyltransferases regulate genes to respond to the oxidative stress in C. albicans. In this review, we introduce all histone acetyltransferases that C. albicans contains and some papers that explain how histone acetyltransferases participate in the oxidative stress response in C. albicans.

Cryptococcus neoformans is a basidiomycete human fungal pathogen that causes meningoencephalitis in both immunocompromised and immunocompetent individuals. The ability to sense and respond to diverse extracellular signals is essential for the pathogen to infect and cause disease in the host. Four major stress-activated signaling (SAS) pathways have been characterized in C. neoformans, including the HOG (high osmolarity glycerol response), PKC/Mpk1 MAPK (mitogen-activated protein kinase), calcium-dependent calcineurin, and RAS signaling pathways. The HOG pathway in C. neoformans not only controls responses to diverse environmental stresses, including osmotic shock, UV irradiation, oxidative stress, heavy metal stress, antifungal drugs, toxic metabolites, and high temperature, but also regulates ergosterol biosynthesis. The PKC(protein kinase C)/Mpk1 pathway in C. neoformans is involved in a variety of stress responses, including osmotic, oxidative, and nitrosative stresses and breaches of cell wall integrity. The $Ca^{2+}$/calmodulin- and Ras-signaling pathways also play critical roles in adaptation to certain environmental stresses, such as high temperature and sexual differentiation. Perturbation of the SAS pathways not only impairs the ability of C. neoformans to resist a variety of environmental stresses during host infection, but also affects production of virulence factors, such as capsule and melanin. A drug(s) capable of targeting signaling components of the SAS pathway will be effective for treatment of cryptococcosis.

This purpose of this study was to identify the meaning and structure of the experiences of women who were most stressed when they live and how they respond to stress when they were stressed.Six Female college students aged 29 years were interviewed for a total of three times until data was saturated and collected until no more data were collected. Interview data was processed through the analysis and interpretation process using the Giorgi phenomenological research method. As a result, 45 semantic units was derived, these were divided again into 12 subcomponents, and then divided into 3 categories. The stress situation of female college students was a way to escape from the stress that arises in situations that were difficult to overcome due to their inability to cope with, and that they were trying to take a walk or listen to music. A young women aged group, female college students becomes the center of the future family. Therefore, their emotional health will be more important than any other class. In conclusion, this study suggests the provision of a young women's tailed program that could help the female college students to experience the stress in the life task positively and to help the stress crisis as a positive experience of life.

The growing demand for more fuel-efficient vehicles to reduce energy consumption and air pollution is a challenge for the automotive industry. The characteristic properties of aluminum, high strengrth stiffness to weight ratio, good formability, good corrosion resistence, and recycling potential make it the ideal candidate to replace heavier materials in the car to respond to the weight resuction demand within the automotive industry. In this paper, A series of compression test was carried out to find the flow stress of A6082 at 300, 400 and $500^{\circ}C$, then we tried to estimate weldability, extrusion load and effective stress of die in the aluminum extrusion process through the 3D FE simulation at non-steady state for aluminum automotive parts.

Purpose: The purpose of this review was to describe a psychoneuroimmunology (PNI) framework for postpartum depression (PPD) and discuss its implications for nursing research and practice for postpartum women. Methods: This study explored the role of hypothalamic-pituitary-adrenal (HPA) axis and inflammation as possible mediators of risk factors for PPD through literature review. Results: From this PNI view, human bodies are designed to respond with the reciprocal interactions among the neuro-endocrine and immune system when they are faced with physical or psychological stressors. Chronic stress induces alterations in the function of HPA axis, and a chronic low-grade inflammatory response is associated with depression. The dysfunctions of cytokines and HPA axis have been observed during the postpartum period. Stress promotes glucocorticoid receptor resistance, which can promote inflammatory responses. This, in turn, can contribute to the pathophysiology of depression. This can especially affect populations at vulnerable time-points, such as women in the postpartum. Conclusion: From a PNI perspective, well-designed prospective research evaluating the role of stress and inflammation as an etiology of PPD and the effect of stress reduction is warranted to prevent PPD.

In recent years, medical and health care fields have attracted attention for virtual reality (VR) applications. VR technology is emerging as a healthcare specialist and psychotherapy alternative to cope with the increase in the demand for the treatment of conditions such as psychological diseases caused by old age and stress. Using VR, virtual patients or organs can be trained, and the medical staff can plan and pre-test before surgeries. The use of VR technology for psychotherapy and rehabilitation of one-to-one, face-to-face treatment allows a single physician to respond to multiple health care needs.

Plasticity is the ability of clay to respond to pressure with a continuous and permanent change of shape in any direction without breaking apart, and hold that shape when released. In this work, the effect of water content and aging period on the plasticity of porcelain clay was evaluated using the capillary rheometer to measure the flow rate and the shear stress. The shear stress of porcelain clay was slightly increased with increasing the aging period, indicating that the plasticity of porcelain clay was influenced by an organic content. It was also observed that the water content in the porcelain clay had a great influence on the plasticity of porcelain clay. The shear stress with water content of 21 wt% was sharply increased with increasing shear rate, but the shear stresses with water contents of 24 and 27 wt% is gently incremented.

Pigs respond to extreme temperature (very cold or hot) by physiological and nutritional adjustments. Yet little is known about the effects of different environmental temperature (thermoneutral in the highland area, and hot temperature in the coastal area) where pigs are maintained on the performance of the pigs. Ten pigs each (10 pairs of littermates) were assigned to two treatments (2 locations): highland area (control=CA) or coastal area (hot/heat stress=HS). Experimental design was Paired 't' test. HS pigs had higher average daily water intake (p<0.05) compared to CA pigs (6,05 vs 3.89 kg/d), CA pigs had higher feed intake compared to HS pigs (2.9 vs 1.95 kg/d, p<0,05). CA pigs had higher daily gain compared to HS pigs (0.72 vs 0.58 kg/d, p<0.05). Feed conversion was not significantly different between CA pigs and HS pigs. The digestibility of dry matter, N, Na, K, Mg, CI, Ca and P was not significantly affected by the treatments. High environmental temperature in the coastal area (heat stress) increased water intake, decreased voluntary feed intake and daily gain of the pigs. The results demonstrate that different environmental temperature in the coastal area (heat stress) and highland area (control) had no pronounced effect on digestibility of nutrients.
