本世纪五十年代中期重新发现了交换性铝,那时,对交换性铝的认识是简单的和一致的,但现在情况已不同了。当然,因为进行了更多的研究我们才逐步知道了一点铝在土壤中的行为,例如聚合物的形成、带羟基铝粘土矿物的层间化以及铅与土壤有机质的相互作用。今天看来,交换性铝的概念仍具有重大的现实意义,但是,它包括的只是土壤中铝的多种存在形式之一。本文讨论了自五十年代以来有关铝的研究结果,并加以评述。

Schizophrenia is a severe mental illness which can have a devastating impact onan individual’s quality of life. Comorbidities are high amongst patients and lifeexpectancy is approximately 15 years less than the general population. Despite thewell-known increased mortality, little is known about the impact of gastrointestinaland liver disease on patients with schizophrenia. We aimed to reviewthe literature and to make recommendations regarding future care. Literaturesearches were performed on PubMed to identify studies related to gastrointestinaland liver disease in patients with schizophrenia. High rates of chronic liverdisease were reported, with Non-Alcoholic Fatty Liver Disease being of particularconcern;antipsychotics and metabolic syndrome were contributing factors. Ratesof acute liver failure were low but have been associated with antipsychotic useand paracetamol overdose. Coeliac disease has historically been linked to schizophrenia;however, recent research suggests that a causal link is yet to be *** is emerging regarding the relationships between schizophrenia andpeptic ulcer disease, inflammatory bowel disease and irritable bowel syndrome;clinical vigilance regarding these conditions should be high. Patients with schizophreniapoorly engage with bowel cancer screening programmes, leading to latediagnosis and increased mortality. Clozapine induced constipation is a significantissue for many patients and requires close monitoring. There is a significantburden of gastrointestinal and liver disease amongst patients with *** levels of support from all members of the medical team are essential toensure that appropriate, timely care is provided.

Magnetohydrostatic modeling of the solar atmosphere

Understanding structures and evolutions of the magnetic fields and plasma in multiple layers on the Sun is very important. A force-free magnetic field which is an accurate approximation of the solar corona due to the low plasma β has been widely studied and used to model the coronal magnetic structure. While the force-freeness assumption is well satisfied in the solar corona, the lower atmosphere is not force-free given the high plasma β. Therefore, a magnetohydrostatic(MHS) equilibrium which takes into account plasma forces, such as pressure gradient and gravitational force, is considered to be more appropriate to describe the lower atmosphere. This paper reviews both analytical and numerical extrapolation methods based on the MHS assumption for calculating the magnetic fields and plasma in the solar atmosphere from measured magnetograms.

Biopsychosocial Aspects of Alzheimer Caregiving: The UCSD Study

引用

上海精神医学 1992年第S1期 77-80页

作者： Igor grant thomas Patterson Richard Hauger Michael Irwin

Because caregiving can be seen as an example of chronic human stress which could produce both physical and mental health changes that may determine the timing of patient placement, we have been conducting studies to determine the psychophysiological effects of caregiving on the elderly spouse. Increasing caregiver burden is related to use of greater escape-avoidant coping, and increased symptoms of depression, anxiety, hostility, and general emotional distress. Caregivers have slightly higher blood pressures, and increased circulating neuropeptide Y, evidence of increased sympatho-adrenal-medullary activation. Caregivers who do not receive adequate respite time also may have hypothalamic-pituitary-adrenal axis activation [increased circulating cortisol and ACTH]. However, not all Caregivers manifest all of these changes.
