Repetitive transcranial magnetic stimulation (rTMS) has been widely used as a therapy for refractory obsessive-compulsive disorder (OCD). However, it remains unclear which exact target and stimulation sequence of rTMS is most effective for OCD. Here, we report the case of an 18-year-old female with treatment-refractory OCD whose symptoms markedly improved after combined rTMS and intermittent theta-burst stimulation over the bilateral dorsolateral prefrontal cortex and supplementary motor area. Our report indicates that combining treatment sequences that stimulate different brain regions sequentially is feasible and may clinically benefit patients suffering from OCD.

Given the conundrum of moral washing in CSR communication, this research examines the effectiveness of narrative richness using storytelling in marketing. In the process, the moderating role of moral imagination is further explored. An online experiment with a 2 (Narrative Richness: High vs. Low) x 2 (Moral Imagination: High vs. Low) between-subjects factorial design was conducted with two well-known companies (Shell vs. Facebook) suffered from a reputation crisis as the target brands. The results (N = 287) showed that the effects of narrative richness on consumer responses, including positive emotion, negative emotion, and behavioral intention, were significant for Facebook whereas its effect on positive emotion was significant for Shell. Most importantly, the two-way interaction between narrative richness and moral imagination on attitude toward the brand was significant for Shell, indicating that the effect of narrative richness on attitude toward the brand was augmented by moral imagination. In other words, consumers with high moral imagination view narrative-rich messages with virtuous thoughts to figure out the conundrum of CSR communication for the company, and vice versa. Theoretical and managerial implications are discussed.

Objective: Genetic high-risk assessment combines hereditary breast, ovarian and pancreatic cancer into one syndrome. However, there is a lack of data for comparing the germline mutational spectrum of the cancer predisposing genes between these three cancers. Methods: Patients who met the criteria of the hereditary breast, ovarian and pancreatic cancer were enrolled and received multi-gene sequencing. Results: We enrolled 730 probands: 418 developed breast cancer, 185 had ovarian cancer, and 145 had pancreatic cancer. Out of the 18 patients who had two types of cancer, 16 had breast and ovarian cancer and 2 had breast and pancreatic cancer. A total of 167 (22.9%) patients had 170 mutations. Mutation frequency in breast, ovarian and pancreatic cancer was 22.3%, 33.5% and 17.2%, respectively. The mutation rate was significantly higher in patients with double cancers than those with a single cancer (p<0.001). BRCA1 and BRCA2 were the most dominant genes associated with hereditary breast and ovarian cancer, whereas ATM was the most prevalent gene related to hereditary pancreatic cancer. Genes of hereditary colon cancer such as lynch syndrome were presented in a part of patients with pancreatic or ovarian cancer but seldom in those with breast cancer. Families with a history of both ovarian and breast cancer were associated with a higher mutation rate than those with other histories. Conclusion: The mutation spectrum varies across the three cancer types and family histories. Our analysis provides guidance for physicians, counsellors, and counselees on the offer and uptake of genetic counseling.

Repetitive transcranial magnetic stimulation (rTMS) and intermittent theta-burst stimulation (iTBS) are evidenced-based treatments for patients with major depressive disorder (MDD) who fail to respond to standard first-line therapies. However, although various TMS protocols have been proven to be clinically effective, the response rate varies across clinical applications due to the heterogeneity of real-world psychiatric comorbidities, such as generalized anxiety dis-order, posttraumatic stress disorder, panic disorder, or substance use disorder, which are often observed in patients with MDD. Therefore, individualized treatment approaches are important to increase treatment response by assigning a given patient to the most optimal TMS treatment protocol based on his or her individual profile. This literature review summarizes different rTMS or TBS protocols that have been applied in researches investigating MDD patients with certain psychiatric comorbidities and discusses biomarkers that may be used to predict rTMS treatment response. Furthermore, we highlight the need for the validation of neuroimaging and electrophysiological biomarkers associated with rTMS treatment responses. Finally, we discuss on which directions future efforts should focus for developing the personalization of the treatment of depression with rTMS or iTBS.
Electron Heating and Current Scaling in a GaAs Two-Dimensional Electron System

We present experimental results on hot-carrier phenomena in a GaAs/AlGaAs two-dimensional electron system in the integer and fractional quantum Hall regions. In the integer region at low magnetic fields, a relationship $T_e$ $\sim$ $I^{0.52}$ between the effective carrier temperature $T_e$ and the source-drain current $I$ is obtained from Shubnikov-de Haas (SdH) oscillations at several magnetic fields, 0.2 $\sim$ 0.5 T, and currents, 0.1 $\sim$ 4 $\mu$A. These results are in agreement with results obtained in the current-dependent broadening of resistance peaks in the quantum Hall region of spin-split Landau levels. However, in the fractional region for the filling factor $\nu = 5/3 (B = 7$ T), a power law relationship $T_e$ $\sim$ $I^{0.37}$ is obtained. The difference in exponent may be due to different energy relaxation mechanisms between these two regions.

Objective: Beclin-1 has recently been observed as an essential marker of autophagy in several cancers. However, the prognostic role of Beclin-1 in colorectal neoplasia remains controversial. Our study aimed to evaluate the potential association between Beclin-1 expression and the outcome of colorectal cancer patients. Materials and Methods: All related studies were systematically searched in Pubmed, Embase, Springer and Chinese National Knowledge Infrastructure databases (CNKI), and then a meta-analysis was performed to determine the association of Beclin-1 expression with clinical outcomes. Finally, a total of 6 articles were included in our analysis. Results: Our data showed that high Beclin-1 expression in patients with CRC was associated with poor prognosis in terms of tumor distant metastasis (OR=2.090, 95%CI=1.061-4.119, p=0.033) and overall survival (RR=1.422, 95%CI=1.032-1.959, p=0.031). However, we did not found any correlation between Beclin-1 over-expression and tumor differentiation (OR=1.711, 95%CI=0.920-3.183, p=0.090). In addition, there was no evidence of publication bias as suggested by Egger's tests for tumor distant metastasis (p=1.000), differentiation (p=1.000) and OS (p=0.308). Conclusions: Our present meta-analysis indicated that elevated Beclin-1 expression iss associated with tumor metastasis and a poor prognosis in patients with CRC. Beclin-1 might serve as an efficient prognostic indicator in CRC, and could be a new molecular target in CRC therapy.

<P>Materials with low crystal symmetry often exhibit anisotropic properties, allowing the tuning of their physical and chemical properties <I>via</I> crystallographic orientation and exposed facet control. Herein, for the first time, we have demonstrated that pristine BiVO4 with a preferred [001] growth orientation and exposed (001) facets exhibits excellent intrinsic charge transport properties and surface reactivity. Using preferentially [001]-oriented BiVO4 (p-BVO) as a photoanode for photoelectrochemical water splitting, an impressive photocurrent density at 1.23 V <I>vs.</I> the reversible hydrogen electrode (RHE) is achieved, which is approximately 16 times higher than that exhibited by a photoanode based on randomly oriented BiVO4. Importantly, when the surface of p-BVO is further roughened and decorated with an oxygen evolution electrocatalyst, photocurrent densities of ∼3.5 and ∼6.1 mA cm<SUP>−2</SUP> are achieved at 0.6 and 1.23 VRHE, respectively; the latter value corresponds to ∼82% of the theoretically achievable photocurrent density for BiVO4 under 1 sun illumination. Our results demonstrate the effectiveness of crystal orientation and exposed facet control in optimizing materials for solar water-splitting applications.</P>
