Hemispheric encoding/retrieval asymmetry in episodic memory: positron emission tomography findings.

Proceedings of the National Academy of Sciences of the United States of America, 1994
Data are reviewed from positron emission tomography studies of encoding and retrieval processes in episodic memory. These data suggest a hemispheric encoding/retrieval asymmetry model of prefrontal involvement in encoding and retrieval of episodic memory.

Defect Engineering in Semiconductor Photocatalysts: Enhancing Photocatalytic Activity for Green Energy Production

Advanced Energy and Sustainability Research, EarlyView.
By creating anion and cation vacancies, scientists fine‐tune semiconductor bandgaps and extend light absorption, boosting charge separation in photocatalysts. Surface defects enhance reactant adsorption and carrier transport, while controlled bulk defects curb recombination.

Rigid Macrocycle Metal Complexes as CXCR4 Chemokine Receptor Antagonists: Influence of Ring Size

Pharmaceutics
Understanding the role of chemokine receptors in health and disease has been of increasing interest in recent years. Chemokine receptor CXCR4 has been extensively studied because of its defined role in immune cell trafficking, HIV infection, inflammatory

The Theory of Diffraction Tomography [PDF]

arXiv, 2015
Tomography is the three-dimensional reconstruction of an object from images taken at different angles. The term classical tomography is used, when the imaging beam travels in straight lines through the object. This assumption is valid for light with short wavelengths, for example in x-ray tomography.

The impact of delayed adjuvant chemotherapy on survival in gastric cancer patients with and without preoperative chemotherapy

Annals of Gastroenterological Surgery, EarlyView.
Delayed initiation of adjuvant chemotherapy (AC) is associated with significantly poorer postoperative survival in patients with gastric cancer, irrespective of whether preoperative chemotherapy was administered. These findings emphasize the importance of timely AC initiation to improve long‐term outcomes in this patient population.

Prognostic factors for patients with esophageal cancer who achieve pathological complete response in the primary tumor after upfront chemotherapy or chemoradiotherapy

Annals of Gastroenterological Surgery, EarlyView.
Male gender and pathological lymph node metastasis are independent poor prognostic factors in patients with esophageal cancer who receive upfront treatment followed by surgery and achieved pathological complete response of the primary tumor. Among patients without pathological lymph node metastasis, the upfront chemotherapy group showed significantly ...

Influence of Facility Size on Perioperative Outcomes in Minimally Invasive Esophagectomy for 14 152 Patients With Esophageal Cancer Based on the Japanese National Clinical Database: A Multicenter Cohort Study

Annals of Gastroenterological Surgery, EarlyView.
This multicenter study investigated 14 152 minimally invasive esophagectomies (MIEs) using data from the Japanese National Clinical Database and showed a significantly lower operative mortality rate in high‐volume centers than in low‐volume centers. However, no differences in morbidity rates were found between facility sizes.

Central hyperthyroidism due to an ectopic TSH-secreting pituitary tumor: a case report and literature review

Frontiers in Endocrinology
Ectopic thyroid-stimulating hormone (TSH)-secreting tumors are extremely rare, with only 15 reported cases in the literature. Herein, we described a 60-year-old female patient with thyrotoxicosis and elevated or unsuppressed levels of TSH. Family history

Robust, self-consistent, closed-form tomography of quantum logic gates on a trapped ion qubit [PDF]

arXiv, 2013
We introduce and demonstrate experimentally: (1) a framework called "gate set tomography" (GST) for self-consistently characterizing an entire set of quantum logic gates on a black-box quantum device; (2) an explicit closed-form protocol for linear-inversion gate set tomography (LGST), whose reliability is independent of pathologies such as local ...
