Dan Sun, Yougen Tang, Delai Ye, Jun Yan, Haoshen Zhou, Haiyan Wang
Morphology controllable fabrication of electrode materials is of great significance but is still a major challenge for high performance Li ion batteries. Herein, we propose a novel space constraint assembly approach to tune the morphology of Mn(terephthalic acid) (PTA)-MOF, in which benzonic acid was employed as a modulator to adjust the available MOF assembly directions. As a result, Mn(PTA)-MOFs with microquadrangulars, microflakes, and spindle-like microrods morphologies have been achieved. MnO/C hybrids with preserved morphologies were further obtained by self-sacrificial and thermal transformation of Mn(PTA)-MOFs...

PRIMARY OBJECTIVES: To assess longitudinal trajectories of overall disability after moderate-to-severe traumatic brain injury (TBI) and to examine whether those trajectories could be predicted by socio-demographic and injury characteristics. METHODS: Demographics and injury characteristics of 105 individuals with moderate-to-severe TBI were extracted from medical records. At the 1-, 2-, and 5-year follow-ups, TBI-related disability was assessed by the GOSE. A hierarchical linear model (HLM) was used to examine functional outcomes up to 5 years following injury and whether those outcomes could be predicted by: time, gender, age, relationship, education, employment pre-injury, occupation, GCS, cause of injury, length of post-traumatic amnesia (PTA), CT findings and injury severity score, as well as the interactions between each of these predictors and time...

Nuclear FOXOs mediate cell cycle arrest and promote apoptosis. FOXOs and p53 could have similar effects as tumor suppressor genes. In spite of extensive literature, little is known about the role of FOXO1 and its relationship with p53 status in bladder cancer. Expression of FOXO1 and p53 were analyzed by immunohistochemistry in 162 urothelial carcinomas (UC). Decreased FOXO1 expression, p53 overexpression and the combination FOXO1 downregulation/p53 overexpression were strongly associated with high grade (P=...

Two manganese(I) carbonyl complexes derived from 2-(pyridyl)benzothiazole (pbt) and 1,10-phenanthroline (phen) release carbon monoxide (CO) under low-power broad-band visible-light illumination. CO photorelease from [Mn(CO)3(pbt)(PTA)]CF3SO3 (1, where PTA = 1,3,5-triaza-7-phosphaadamantane) is accompanied by an emergence of a strong fluorescence around 400 nm from almost nonfluorescent preirradiated 1. However, [Mn(CO)3(phen)(PTA)]CF3SO3 (2) showed no such phenomenon upon prolonged illumination under similar experimental conditions...

The complexes of Cu(i) and Ag(i) with 1,3,5-triaza-7-phosphadamantane (PTA) are currently studied for their potential clinical use as anticancer agents, given the cytotoxicity they exhibited in vitro towards a panel of several human tumor cell lines. These metallodrugs are prepared in the form of [M(PTA)4](+) (M = Cu(+), Ag(+)) compounds and dissolved in physiological solution for their administration. However, the nature of the species involved in the cytotoxic activity of the compounds is often unknown. In the present work, the thermodynamics of formation of the complexes of Cu(i) and Ag(i) with PTA in aqueous solution is investigated by means of potentiometric, spectrophotometric and microcalorimetric methods...

A persistent trigeminal artery (PTA) is the most common carotid-vertebrobasilar anastomosis. PTA variants terminating on cerebellar arteries instead of the basilar artery have been reported previously. We present the first case of a PTA communicating with a fetal posterior communicating artery identified on a magnetic resonance angiogram. An understanding of these anatomical variants is important to clarify pathological processes that can help guide neurosurgical and endovascular procedures.

This study describes the realization of an anoxic acetoin production process using the proteobacterium Shewanella oneidensis. Fermentative processes are of high biotechnological relevance since they offer high productivity and a low percentage of substrate consumption for anabolic processes. Nevertheless, the range of compounds that can be produced as sole end product of a fermentative process is limited, since the average oxidation state of substrate and products has to be identical in the absence of an external electron acceptor...

OBJECTIVE: Endolymphatic sac decompression (ESD) for the treatment of Ménière's disease (MD) has had limited success and variable results in the literature. We have devised a novel technique that involves blocking the endolymphatic duct with surgical clips. In a separate effort to study the endolymphatic sac (ELS), we have sectioned the lateral part of the main body of the ELS as biopsies from a subset of patients. We aimed to evaluate the effect of the lateral part sectioning of the ELS on short-term surgical outcomes...
