This paper demonstrates three vibrational spectroscopic techniques and their applications in characterization of spatially heterogamous materials, namely step-scan phase modulation FTIR photoacoustic spectroscopy (S2MPAS), visible (confocal) Raman microscopy (CRM) and FT-IR imaging. In addition, the applications of Raman spectroscopy in nanomaterials studies are also briefly discussed.

Urinary incontinence and hematuria are frequent complaints evaluated by urologists often with readily identifiable etiologies. Occasionally, an unlikely source is found. We present an unusual case of urinary incontinence and hematuria in an elderly female. Evaluation revealed that the complaints were due to a large cyst emanating from her right hip which was the result of a previous right hip arthroplasty in 1970 with three subsequent revisions. Her symptoms resolved spontaneously and the cyst has remained unchanged.

Given that alcohol use is highly prevalent at US colleges, we explored factors related to problem drinking behaviors (PDB;binge drinking, driving after drinking, sexual intercourse after drinking) among 4098 Black and White students from two- and four-year colleges who completed an online survey. We found an interaction between race and sex such that, among Whites, females had less PDB than males (B = 0.09, CI: 0.05;0.40, p = 0.01). An interaction between race and school type also existed, such that White students from four-year schools had greater PDB (B = 0.11, CI: 0.20;0.54, p < 0.001). An interaction between race and stress suggested that Black students were more negatively affected by stress in terms of PBD (B = 0.12, CI: 0.01;0.07, p = 0.01).

在教学设计和技术(IDT)领域,众多的学者、研究者和工作者对建构主义颇为信奉,但建构主义的提倡者却努力从建构主义的理论向建构主义的实践迈进,并试图通过实证的方式来证实其方法的有效性。作为对建构主义的一种替代,在心理学领域出现了一种新的观点,即功能情境主义。同建构主义一样,功能情境主义也反对目标认识论,但它却提供了更加连贯一致的哲学基础。基于这个基础,能够建构一种学习和教学的务实科学。本研究首先通过对情境主义哲学世界观的回顾,分析了建构主义和功能情境主义的异同,接着论述了功能情境主义的关键特征、其所支持的科学及行为分析,然后探讨了功能情境主义对IDT研究和实践的启示。

A 67-year-old woman underwent an orthotopic liver transplantation for end stage liver disease secondary to chronic autoimmune hepatitis. She developed sudden massive hematochezia on post-operative day 23 with hemodynamic compromise. The source of hemorrhage was found at colonoscopy after careful irrigation and inspection to be a dieulafoy lesion situated just proximal to the anorectal junction. Hemostasis was achieved with epinephrine injection and thermal coagulation.

Background: The etiology and treatment of spontaneous paralysis variants of anterior interosseous nerve (AIN) syndrome remains controversial. Variation and multiple sites of potential compression complicate the successful performance of neurolysis. This anatomic study of the AIN and sites of potential compression in the proximal forearm facilitates critical steps involved in neurolytic procedures and management. Methods: Upper extremities of twelve cadavers were examined to evaluate potential sites of AIN compression in the proximal forearm. Potential sites of musculoaponeurotic compression were evaluated, including: lacertus fibrosus;inferior fibrous arch of the humeral head of the pronator teres (PT) muscle;inferior fibrous arch of the ulnar head of the PT muscle;fibrous arch in the flexor digitorum superficialis (FDS) muscle;Gantzer’s muscle;and vascular structures near the AIN and median nerve. Results: The AIN arose at a mean distance of 54.5 mm distal to the elbow from the posterior (n = 9) or ulnar side (n = 3) of the median nerve. Relative positions of AIN branches were variable. A fibrous arch was found between the lacertus fibrosus and the PT in two cases. Nine cadavers had two fibrous arches in the PT and FDS, and three cadavers had one arch. An accessory head in the FDS was found to be a risk of AIN compression. Gantzer’s muscle was present in six cases, crossing the AIN superficially. Two potentially compressive vascular arches were identified. Conclusions: Our observations confirm that multiple musculoaponeurotic and/or vascular structures can contribute to AIN compression in the proximal forearm. Understanding the complex anatomic relationships of this nerve is crucial to improving outcomes of neurolysis in cases of non-regressive AIN paralysis.
