Standardization and quantification of backscattered electron imaging in scanning electron microscopy.

Backscattered electron (BSE) imaging based on scanning electron microscopy (SEM) has been widely used in scientific and industrial disciplines. However, achieving consistent standards and precise quantification in BSE images has proven to be a long-standing challenge. Previous methods incorporating dedicated calibration processes and Monte Carlo simulations have still posed practical limitations for widespread adoption.

Time-resolved X-ray reflection phases of the nearly forbidden Si(222) reflection under laser excitation.

The covalent electron density, which makes Si(222) measurable, is subject to laser excitation. The three-wave Si(222)/(13 {\overline 1}) diffraction at 7.82 keV is used for phase measurements.

High-resolution monochromator using a high-efficiency single-mode x-ray resonator at Laue incidence.

We report a high-resolution and high-efficiency monochromator with energy resolution, ΔE/E∼2.08*10, utilizing a hard x-ray single-mode Fabry-Perot (FP) resonator at Laue incidence at 14.4388 keV.

Sentinel Artery in Double Eyelid Blepharoplasty: Identification, Prevention, Management.

In double eyelid blepharoplasty, unexpected bleeding may cause intraoperative hematoma, swelling, and temporary ptosis, which could cause asymmetry and prolong recovery time. In 1725 patients (3450 eyes), double eyelid blepharoplasties were performed on Chinese patients from January 2014 to July 2016 by our senior author. In 36 eyes, the authors identified a variant artery, which the authors named the "sentinel artery," located in the inferolateral superficial orbital septum.

The effect of cranioplasty in cognitive and functional improvement: Experience of post traumatic brain injury inpatient rehabilitation.

To investigate the effect of cranioplasty on rehabilitation of post-traumatic brain injury (TBI) patients, 37 patients with TBI were arranged by retrospectively assessment study. Those TBI patients receiving in-hospital rehabilitation in the Department of Rehabilitation in a medical center of South Taiwan from 2010 to 2015 were assigned into two groups: A and B. All patients entered the multidisciplinary holistic in-patient rehabilitation training for about 1 month.

Regulation of miR-21 expression in human melanoma via UV-ray-induced melanin pigmentation.

Excessive environmental ultraviolet (UV) radiation produces genetic mutations that can lead to skin cancer. This study was designed to assess the potential inhibitory activity of microRNA-21 (miR-21) on the UV irradiation-stimulated melanogenesis signal pathway in melanoma cells. The molecular mechanism of miR-21-induced inhibitory activity on UV-ray-stimulated melanogenesis-regulating proteins was examined in A375.

High-resolution interference-monochromator for hard X-rays.

An X-ray interference-monochromator combining a Fabry-Perot resonator (FPR) and a double-crystal monochromator (DCM) is proposed and realized for obtaining single-mode X-rays with 3.45 meV energy resolution. The monochromator is based on the generation of cavity interference fringes from a FPR and single-mode selection of the transmission spectrum by a DCM of a nearly backward symmetric reflection geometry.

Sapphire hard X-ray Fabry-Perot resonators for synchrotron experiments.

Hard X-ray Fabry-Perot resonators (FPRs) made from sapphire crystals were constructed and characterized. The FPRs consisted of two crystal plates, part of a monolithic crystal structure of Al2O3, acting as a pair of mirrors, for the backward reflection (0 0 0 30) of hard X-rays at 14.3147 keV.

RISK OF NEW ONSET TYPE II DM IN MDD PATIENTS RECEIVING SECOND-GENERATION ANTIPSYCHOTICS TREATMENT: A NATIONWIDE COHORT STUDY.

Background: Second-generation antipsychotics (SGA) augmentation treatment has showed better efficacy in patients with major depressive disorder (MDD). However, the association between SGA and diabetes mellitus (DM) in MDD patients deserves further investigation. The study aimed to examine the risk of new onset type II DM in MDD patients receiving SGA treatment.

Adjunctive sarcosine plus benzoate improved cognitive function in chronic schizophrenia patients with constant clinical symptoms: A randomised, double-blind, placebo-controlled trial.

Objectives Hypofunction of NMDA receptor is implicated in the pathophysiology, particularly cognitive impairment, of schizophrenia. Sarcosine, a glycine transporter I (GlyT-1) inhibitor, and sodium benzoate, a d-amino acid oxidase (DAAO) inhibitor, can both enhance NMDA receptor-mediated neurotransmission. We proposed simultaneously inhibiting DAAO and GlyT-1 may be more effective than inhibition of either in improving the cognitive and global functioning of schizophrenia patients.

Single-mode selection for hard x-ray cavity resonance.

Single-mode selection is realized for hard x-ray cavity resonance using a three-mirror crystal device. The developed device consists of two coupled Si Fabry-Perot resonators (FPRs) and uses (12 4 0) backward diffraction to reflect back and forth the incident 14.4388 keV x-ray beam.

Effectiveness of aripiprazole, olanzapine, quetiapine, and risperidone augmentation treatment for major depressive disorder: a nationwide population-based study.

Objective: Previous studies suggested that antidepressants augmented with second-generation antipsychotics (SGAs), including aripiprazole, olanzapine, quetiapine, and risperidone, resulted in better treatment response or higher rates of remission in patients with major depressive disorder (MDD). However, population-based study on SGA augmentation for patients with MDD remains limited. The purpose of this study was to investigate the effectiveness of SGA augmentation for treatment of MDD using the National Health Insurance Research Database in Taiwan.

Inverse association between cancer risks and age in schizophrenic patients: a 12-year nationwide cohort study.

The association between schizophrenia and cancer risk is contentious in the clinical and epidemiological literature. Studies from different populations, tumor sites, or health care systems have provided inconsistent findings. In the present study, we examined a less well-investigated hypothesis that age plays a crucial role in cancer risk in schizophrenia.

Tumor necrosis factor-α induces epithelial-mesenchymal transition of renal cell carcinoma cells via a nuclear factor kappa B-independent mechanism.

Chronic low dose of tumor necrosis factor-α (TNF-α) stimulation promotes tumorigenesis by facilitating tumor proliferation and metastasis. The plasma levels of TNF-α are increased in patients with renal cell carcinoma (RCC). Furthermore, high-grade clear cell RCC cell lines secrete more TNF-α than low-grade ones, and allow low-grade cell lines' gain of invasive ability.

Tumor-derived tumor necrosis factor-alpha promotes progression and epithelial-mesenchymal transition in renal cell carcinoma cells.

Pro-inflammatory cytokines and chemokines are involved in promoting tumorigenesis by facilitating tumor proliferation and metastasis. The serum levels of interleukin (IL)-6, IL-1 beta, and tumor necrosis factor-alpha (TNF-alpha) are significantly elevated in patients with renal cell carcinoma (RCC). However, the mechanisms of how these cytokines participate in the progression of RCC remains unknown.

Relationship between post-stroke depression and lesion location: a meta-analysis.

Our understanding of the relationship between the neuroanatomic loci of brain damage and the incidence of post-stroke depression (PSD) is not complete. Many studies have investigated this relationship and the evidence is conflicting. With the purpose of gaining a consistent, strong, and credible conclusion on the relationship between PSD and the loci of brain damage, a meta-analysis was used in this study to systematically reanalyze the findings of related studies and to investigate the sources of heterogeneity among study results.

Acute renal failure after uterine artery embolization.

Renal failure is a potential complication of any endovascular procedure using iodinated contrast, including uterine artery embolization (UAE). In this report we present a case of acute renal failure (ARF) following UAE performed as a treatment for uterine fibroids. The likely causes of ARF in this patient are explored and the possible etiologies of renal failure in patients undergoing UAE are reviewed.
