Constructing Equity Investment Strategies Using Analyst Reports and Regime Switching Models.

This study demonstrates whether analysts' sentiments toward individual stocks are useful for stock investment strategies. This is achieved by using natural language processing to create a polarity index from textual information in analyst reports. In this study, we performed time series forecasting for the created polarity index using deep learning, and clustered the forecasted values by volatility using a regime switching model.

Unusually large ephedrine-induced blood pressure increases due to cardiac sympathetic denervation supersensitivity in a patient with Parkinson's disease.

Background: Parkinson's disease (PD) patients often suffer from cardiac sympathetic denervation, a hallmark of which is orthostatic hypotension. Denervation supersensitivity to sympathomimetic drugs is also seen in such patients, and this phenomenon is important and can be sometimes dangerous.

Case Presentation: A 65-year-old male underwent gastrojejunostomy.

[The Actual State of Treatment of Gastrointestinal Cancer with Abdominal Aortic Aneurysm in Our Department over the Past Five Years].

With the aging of the population of Japan and Westernization of the dietary life, the number of cases in which cardiovascular diseases are merged in non-cardiac surgery is increasing year by year.Many of the abdominal aortic aneurysms are asymptomatic and it is not uncommon to be discovered accidentally in preoperative examination of non-cardiac surgery.When gastrointestinal surgery involves malignant diseases of the gastrointestinal tract and abdominal aortic aneurysm, the two life prognosis-related diseases are merged, depending on the severity and urgency of the disease for each case, its treatment to determine the priority order.

Formation of layered perovskite structure by folding monolayer during compression.

The morphology and layered structure of an alkyl ammonium bromide ultrathin film prepared on an aqueous solution of lead bromide were investigated on the basis of surface pressure-area curve measurements, reflection spectrum measurements, X-ray reflectivity measurements and atomic force microscopic observations. It became apparent that the layered structure sandwiched a two-dimensional inorganic layer between two organic monolayers was formed by folding the monolayer by compression on an aqueous PbBr2 solution.

Three-dimensional CT image analysis of a tracheal bronchus in a patient undergoing cardiac surgery with one-lung ventilation.

The incidence of a tracheal bronchus--that is, a congenitally abnormal bronchus originating from the trachea or main bronchi--is 0.1%-2%. Serious hypoxia and atelectasis can develop in such patients with intubation and one-lung ventilation.

Daedalin A, a metabolite of Daedalea dickinsii, inhibits melanin synthesis in an in vitro human skin model.

The culture broth of Daedalea dickinsii was found to predominantly contain the tyrosinase inhibitor, (2R)-6-hydroxy-2-hydroxymethyl-2-methyl-2H-chromene, daedalin A (1). Ongoing research into bioactive metabolites resulted in the identification of two new 2H-chromenes, 6-hydroxy-5,7-dimethoxy-2,2-dimethyl-2H-chromene (3) and 6-hydroxy-2-hydroxymethyl-5-methoxy-2-methyl-2H-chromene (4), together with 6-hydroxy-2,2-dimethyl-2H-chromene (2). Comparative studies of isolated compounds 1-4 and related compounds (+/-)-1 and 1a-1c showed 1 to have the strongest tyrosinase inhibitory activity.
