Monkeys that receive chronic low-dose 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine (MPTP) administration have difficulty performing numerous cognitive tasks. This study further examines the extent to which chronic low-dose MPTP exposure affects performance of a visual memory task [variable delayed response (VDR)] with both attentional and short-term memory components and assesses the effects o...

OBJECTIVE The research quantitatively evaluates the dosimetric advantage of a helical tomotherapy (HT) intensity-modulated radiation therapy simultaneous integrated boost (SIB) compared to a conventional HT sequential (SEQ) boost for primary intracranial tumors. METHODS Hypothetical lesions (planning target volumes or PTVs) were contoured within computed tomography scans from normal controls....

1. Sib mating avoidance is a pervasive behaviour, which likely evolves in species that sare subject to inbreeding depression. Laboratory studies have provided elegant demonstrations, but small-scale bioassays often minimize the costs associated with mate finding and mate-choice and may for this reason produce spurious findings. 2. We inferred the mating behaviour of the parasitoid wasp Venturia...

Ionic liquids (ILs) were synthesized inside a porous metal-organic framework (MIL-101) via a ship-in-bottle (SIB) technique. Unlike previously reported IL-incorporated MIL-101s, IL@MIL-101 prepared by the SIB approach was very stable over several cycles for the liquid phase adsorption of benzothiophene from liquid fuel.

Background: This study was performed to assess patient survival and treatment toxicity after helical tomotherapy (HT) with simultaneous integrated boost (SIB) radiotherapy (RT) for cancer patients with one to eight brain metastases (BM) who have been treated with or without surgery. Materials and Methods: A total of 48 brain metastasis (BM) patients were included in this retrospective study bet...

OBJECTIVE To identify whether the combination of pre-treatment radiological and clinical factors can predict the overall survival (OS) in patients with locally advanced pancreatic cancer (LAPC) treated with stereotactic body radiation and sequential S-1 (a prodrug of 5-FU combined with two modulators) therapy with improved accuracy compared with that of established clinical and radiologic risk ...

Monkeys that receive chronic low dose (CLD) 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration develop deficits in spatial delayed-response task performance. The present study examined the extent to which SIB-1553A [(+/-)-4-[[2-(1-methyl-2-pyrrolidinyl)ethyl]thio]phenol hydrochloride], a novel neuronal nicotinic acetylcholine receptor (nAChR) agonist with selectivity for beta4 s...

PURPOSE To compare lesional stereotactic radiosurgery to whole brain (WBRT) radiotherapy with simultaneous in-field boost for brain metastases in terms of overall survival. METHODS A retrospective review was performed on two institutional databases of 500 patients diagnosed with brain metastatic disease who received either stereotactic radiosurgery (SRS, n = 381) or whole brain with simultane...

AIMS To report the feasibility of volumetric modulated arc therapy (VMAT) for neoadjuvant radiotherapy in locally advanced rectal cancer in a dose-escalation protocol and simultaneous integrated boost (SIB) approach. Moreover, the VMAT technique was compared with three-dimensional conformal radiotherapy (3D-CRT) and fixed-field intensity modulated radiotherapy (IMRT), in terms of target coverag...

AIM In recent years, the intensity-modulated radiotherapy with simultaneous integrated boost (IMRT-SIB) and intensity-modulated radiotherapy with conventional fractionation (IMRT-CF) have been involved in the treatment of nasopharyngeal carcinoma (NPC). However, the potential clinical effects and toxicities are still controversial. METHODS Here, 107 patients with biopsy-proven locally advance...
