INTRODUCTION: Maintaining the relative dose intensity (RDI) of adjuvant chemotherapy at ≥ 85% has been associated with improved treatment outcomes in early-stage breast cancer (ESBC). Increasing evidence has suggested that patients aged ≥ 65 years can maintain the optimal RDI for standard chemotherapy regimens. The present study investigated the RDI of newer adjuvant chemotherapy regimens in this demographic. PATIENTS AND METHODS: We retrospectively analyzed the data from 281 patients aged ≥ 65 years with a diagnosis of ESBC who had received adjuvant chemotherapy across 3 sites in Queensland, Australia from 2010 to 2015...

The rate of segmental resection for early stage non-small cell lung carcinoma (NSCLC) is increasing. However, the indications remain controversial. The aim of this study is to analyze the preliminary results of thoracoscopic segmental resection in early stage NSCLC in terms of morbidity, oncological validity and survival. We report the preliminary results of a consecutive series of 226 thoracoscopic segmentectomies for suspicion of early stage NSCLC. PATIENTS AND METHODS: Between 2007 and 2016, we performed 322 thoracoscopic anatomical sublobar resections (ASLR)...

Filial imprinting is the behavior observed in chicks during the sensitive or critical period of the first 2-3 days after hatching; however, after this period they cannot be imprinted when raised in darkness. Our previous study showed that temporal augmentation of the endogenous thyroid hormone 3,5,3'-triiodothyronine (T3 ) in the telencephalon, by imprinting training, starts the sensitive period just after hatching. Intravenous injection of T3 enables imprinting of chicks on days 4 or 6 post-hatching, even when the sensitive period has ended...

Monocyte locomotion inhibitory factor (MLIF, Met-Gln-Cys-Asn-Ser), a pentapeptide with anti-inflammatory activity, was developed for neural protection in acute ischemic stroke. Determination of MLIF in human plasma samples is of great importance for pharmacokinetic evaluation in clinical studies. A reliable and sensitive method based on ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) was established for the measurement of MLIF in human plasma. Instability of peptide in matrix was the primary challenge in method development, which was properly resolved by addition of acidification reagents like sulfuric acid...

Since its publication, Aharonov and Vaidman's three-box paradox has undergone three major advances: i). A non-counterfactual scheme by the same authors in 2003 with strong rather than weak measurements for verifying the particle's subtle presence in two boxes. ii) A realization of the latter by Okamoto and Takeuchi in 2016. iii) A dynamic version by Aharonov et al. in 2017, with disappearance and reappearance of the particle. We now combine these advances together. Using photonic quantum routers the particle acts like a quantum "shutter...
