Fluorescence-based Heme Quantitation in Toxoplasma Gondii.
The Mill-Whewell debate has been taken to exemplify this shift in scientific epistemology, with Whewell's consequentialism prevailing over Mill's defense of the older standard. However, Bernard's reflections on biological practice challenge the received view. His methodology marked a significant extension of the vera causa standard that made it both powerful and practicable. In particular, Bernard emphasized the importance of detection procedures in establishing the existence of unobservable entities. Moreover, his sophisticated notion of controlled experimentation permitted inferences about competence even in complex biological systems. In the life sciences, the vera causa standard began to flourish precisely around the time of its alleged abandonment.In his book, The Material Theory of Induction, Norton argues that the quest for a universal formal theory or 'schema' for analogical inference should be abandoned. In its place, he offers the "material theory of analogy" each analogical inference is "powered" by a local fact of analogy rather than by any formal schema. His minimalist model promises a straightforward, fact-based approach to the evaluation and justification of analogical inferences. This paper argues that although the rejection of universal schemas is justified, Norton's positive theory is limited in scope it works well only for a restricted class of analogical inferences. Both facts and quasi-formal criteria have roles to play in a theory of analogical reasoning.The sustained failure of efforts to design an infinite lottery machine using ordinary probabilistic randomizers is traced back to a problem familiar to set theorists we have no constructive prescriptions for probabilistically non-measurable sets. Yet construction of such sets is required if we are to be able to read the result of an infinite lottery machine that is built from ordinary probabilistic randomizers. All such designs face a dilemma they can provide an accessible (readable) result with probability zero; or an inaccessible result with probability greater than zero.Advancing age is associated with increasing risk of activities important for independence, such as driving and living alone. Cognitive impairment is more common with older age; financial resources and social support may dwindle. Afatinib Risk, cognitive impairment, and decisional capacity each change over time. Transparent decision making and harm reduction help balance risk and safety. When a patient lacks decisional capacity, an option that considers the patient's preferences and shows respect for the person is favored. Vulnerable patients making choices that are high risk, and patients for whom others are making such choices, may require state intervention.Geriatric patients are not just older adult patients. Aging brings about unique physiologic, psychological, and sociologic changes within individuals. Recognition of these unique characteristics and measuring for their impact; instituting mitigating strategies; using age-specific anesthetic measures; and performing a systematic, algorithmic care model in the postoperative period overseen by a multidisciplinary team brings about enhanced outcomes and improved quality of care for this expanding group of patients.This article reviews the evaluation of 4 vexing symptoms for elderly patients in primary care leg cramps, dizziness, insomnia, and weight loss. For each, ideal evaluations are proposed.Osteoporosis and osteoporosis-related fractures are common causes of morbidity and mortality in older adults. Healthy adults should be counseled about measures to prevent osteoporosis. Women should be screened for osteoporosis beginning at age 65. Screening for osteoporosis in men should be considered when risk factors are present. Appropriate screening intervals are controversial. Women and men with osteoporosis should be offered pharmacologic therapy. Choice of therapy should be based on safety, cost, convenience, and other patient-related factors. Bisphosphonates are a first-line therapy for many patients with osteoporosis. Other treatments for osteoporosis include denosumab, teriparatide, abaloparatide, romosozumab, and selective estrogen receptor modulators.Persistent pain in older adults is a widely prevalent and disabling condition that is the manifestation of multiple contributing physical, mental, social, and age-related factors. To effectively treat pain, the clinician must assess and address contributing factors using a comprehensive approach that includes pharmacologic and nonpharmacologic therapies within the context of a strong therapeutic relationship among the patient, caregivers, and a multidisciplinary team. This article reviews the current understanding of persistent pain in older adults and suggests a general approach to its assessment and management, followed by specific considerations for musculoskeletal pain conditions commonly seen in older adults.Older adults experience greater emotional well-being in late life. However, older adults may be vulnerable to certain physiologic risk factors, including less physiologic resilience to prolonged stress. Depression and anxiety can be difficult to diagnose in late life owing to differences in self-reported symptoms from younger adults and unclear distinctions between normative and non-normative emotional experiences. We discuss age differences in the presentations of depression and anxiety, and normative and non-normative late life developmental trajectories around bereavement and grief, social isolation and loneliness, and thoughts of death and suicide. We provide recommendations for clinicians for assessing and diagnosing older adults.The prevalence of urinary incontinence and other lower urinary tract symptoms increases with older age. These symptoms are more noticeable in men after the seventh decade of life and in women after menopause. Constipation and fecal incontinence are major causes of symptoms in elderly patients and can significantly impair quality of life. This article summarizes the current literature regarding the occurrence and implications of lower urinary tract and bowel symptoms in the geriatric population.
