Preparation of enantioenriched helical- and axial-chiral molecules by dynamic asymmetric induction.

Dynamic asymmetric induction (DYASIN) of racemic dynamic chiral heterohelicenes afforded their highly enantioenriched forms (up to 96% ep) in quantitative yields. These heterohelicenes were readily converted into semi-static axial-chiral 1,1'-binaphthyl derivatives in a stereospecific manner.

[IMPORTANCE OF SCREENING FOR LUNG LYMPHANGIOLEIOMYOMATOSIS AMONG RENAL ANGIOMYOLIPOMA CASES].

(Background) Multiple renal angiomyolipoma (AML) may develop concurrently with tuberous sclerosis complex (TSC) and lung lymphangioleiomyomatosis (LAM). In recent years, an increase in subjects undergoing chest computed tomography examinations, including medical examinations, has been accompanied by an increase in LAM cases that are diagnosed while still asymptomatic. Surgical treatment may also be performed for renal AML to prevent bleeding.

Relationships between estimation errors and falls in healthy aged dwellers.

Background: Although fall predictions using motor ability have been well reported in elderly people, there are few reports on physical cognitive ability.

Objective: To examine the relationship of the results of motor function tests that include physical cognitive ability on the ability to predict falls and to determine which test is the most appropriate.

Methods: We studied 174 community-dwelling elderly adults (mean age 75.

Pre- and perioperative factors affecting infection after living donor liver transplantation.

Objective: Infectious complications, including sepsis, that often occur after liver transplantation (LT) comprise the most frequent causes of in-hospital death. This study investigated the predictors of post-transplantation infectious complications to establish a strategy with which to improve short-term outcomes after LT.

Methods: We used univariate and multivariate analyses to assess pre- and perioperative risk factors for post-transplantation infectious complications in 100 consecutive patients who underwent living donor LT from February 2008 through February 2010 at our institute.

Esophageal small-cell carcinoma with syndrome of inappropriate secretion of antidiuretic hormone.

Small-cell carcinoma (SCC) of the esophagus is rare, and its clinical characteristics remain poorly understood. A 54-year-old man was given a diagnosis of esophageal SCC and underwent esophagectomy. Four months after surgery, he was admitted to our hospital because of rapidly developing hyponatremia.

Initial steroid bolus injection promotes vigorous CD8+ alloreactive responses toward early graft acceptance immediately after liver transplantation in humans.

We have found that steroid bolus withdrawal prior to graft reperfusion increased the incidence of acute cellular rejection (ACR). This study aims to clarify how initial steroid bolus (ISB) injection at reperfusion influences the kinetics of CD8(+) alloreactive immune responses immediately after living donor liver transplantation (LDLT). A total of 49 hepatitis C virus (HCV)-infected recipients were classified into 3 groups according to hierarchical clustering by preoperative CD8(+)CD45 isoforms.

Identification of hydroxyl radicals after UV irradiation of aqueous extracts of cigarette smoke and evaluation of urinary 8-OHdG in smokers.

The role of oxidative stress in tobacco smoke damage was examined using a combination of in vitro and in vivo approaches. Aqueous extracts of cigarette smoke were irradiated with UV and hydroxyl radical generation was evaluated by electron spin resonance (ESR). The spectra obtained revealed spin adducts of the hydroxyl radical (*OH) to increase with the volume of the aqueous extract of cigarette smoke, cigarette smoke collection flow, and UV irradiation time.
