Autophagy and Tumor Database: ATdb, a novel database connecting autophagy and tumor.

Autophagy is an essential cellular process that is closely implicated in diverse pathophysiological processes and a variety of human diseases, especially tumors. Autophagy is regarded as not only an anti-cancer process in tumorigenesis but also a pro-tumor process in progression and metastasis according to current research. It means the role of autophagy in tumor is considered to be complex, controversial and context dependent.

Neuroprotective effect of Hongjing I granules on erectile dysfunction in a rat model of bilateral cavernous nerve injury.

Neurogenic erectile dysfunction (NED) is an inevitable postoperative disease of cavernous nerve injury which will lead to various pathophysiological changes in the corpus cavernosum and dorsal penile nerve caused by radical prostatectomy (RP). Although serval years of clinical application of HJIG I granules (HJIG), an innovative formulation, has demonstrated its reliable clinical efficacy against NED, the mechanism of HJIG remains unclear. This study aimed to assess the neuroprotective effect of HJIG, to repair damaged nerves in a rat model of bilateral cavernous nerve injury (BCNI) in vivo and their effects on neurites of major pelvic ganglia (MPG) regeneration and Schwann cells (SCs) proliferation in vitro.

Salidroside Attenuates Hypoxia-Induced Expression of Connexin 43 in Corpus Cavernosum Smooth Muscle Cells.

Introduction: Connexin 43 (Cx43) is the major component of gap junction in corpus cavernosum smooth muscle, which allows rapid intercellular communication. Cx43 coordinates corpus cavernosum smooth muscle cells and ensures erectile function. The role of hypoxia in Cx43 dysfunction resulting in erectile dysfunction has not been well studied, and salidroside has shown cell protective effects under hypoxia.

RHPN1-AS1 promotes cell proliferation and migration via miR-665/Akt3 in ovarian cancer.

Recent efforts have revealed that long non-coding RNAs exert crucial roles in cancer initiation and progression.

Can mental time lines co-exist in 3D space?

A growing body of evidence suggested that time can be represented separately either on the lateral, sagittal or vertical axis. However, it is still not clear whether these mental time lines from different origins could co-exist, or compete with each other such that if one is selected, the others are inhibited? The present study addressed this question using a multi-dimensional free-choice paradigm with Mandarin speakers in three experiments. The results showed that significant spatial-temporal congruency effects were found both on the lateral and sagittal/vertical axes in the horizontal/coronal plane either in a temporal judgment relevant or irrelevant task.

Cracking Behavior of René 104 Nickel-Based Superalloy Prepared by Selective Laser Melting Using Different Scanning Strategies.

Eliminating cracks is a big challenge for the selective laser melting (SLM) process of low-weldable Nickel-based superalloy. In this work, three scanning strategies of the snake, stripe partition, and chessboard partition were utilized to prepare René 104 Ni-based superalloy, of which the cracking behavior and the residual stress were investigated. The results showed that the scanning strategies had significant effects on the cracking, residual stress, and relative density of the SLMed René 104 superalloy.

Inhibition of protective immunity against infection by MHC-restricted immunodominance is overcome by vaccination.

Recurrent infections are common, despite robust immune responses. infection elicited protective antibody and T cell responses in mice that expressed the Major Histocompatibility Complex (MHC) of the H-2 haplotype, but not H-2, demonstrating that host genetics drives individual variability. Vaccination with a-toxin or leukotoxin E (LukE) elicited similar antibody and T cell responses in mice expressing H-2 or H-2, but vaccine-elicited responses were inhibited by concomitant infection in H-2-expressing mice.

[Sonic hedgehog signaling pathway and erectile dysfunction: Advances in studies].

Sonic hedgehog (Shh) is an important regulator of penile erectile function in adult males, and abnormal Shh signals may be involved in the mechanisms of ED. Current studies on the relationship of the Shh signaling pathway with ED are mainly concentrated on neurogenic ED caused by bilateral cavernous nerve injury, diabetes-induced endocrinological ED, and senile ED. This review focuses on the changes of the Shh signaling pathway in different types of ED and clarifies the mechanisms of the Shh signaling pathway regulating ED, hoping to give some inspiration to further related studies.

The optimum concentration of H2O2 for intervention was determined by detecting its effect on the viability of the CCSMCs and used in the treatment of the CCSMCs for different lengths of time, and meanwhile salidroside was applied at 16 μg/ml (low dose) or 64 μg/ml (high dose) for intervention.

Recognizing the role of plant species composition in the modification of soil nutrients and water in rubber agroforestry systems.

Reliable guidance for crop selection and related management to achieve sustainable soil resource use in rubber agroforestry systems is limited. One important reason for this limited guidance is that our understanding of the effects of different plant functional groups on soil resources is still insufficient. Here, to examine the effects of the species composition of trees, shrubs and herbs on soil nutrients and soil water with increases in the complexity of the plant community structure, we measured the soil nutrient concentrations (i.

Iodinated poly(-dioxanone) as a facile platform for X-ray imaging of resorbable implantable medical devices.

Background: Luman is a member of CREB3 (cAMP responsive element-binding) subfamily of the basic leucine-zipper (bZIP) transcription factors. It may play an important regulatory role during the decidualization process since Luman was highly expressed in the decidual cells. However, the exact molecular mechanisms of how Luman regulating decidualization is unknown.

[Spatial heterogeneity of soil fungal diversity in area with presence of Stellera chamaejasme on the degraded alpine meadow].

Stellera chamaejasme is one of the most serious weeds in Qinhai-Tibetan Plateau, the rapid expansion of which exerts an increasing effect on the alpine meadow ecosystem. With high-throughput sequencing technology, geostatistics and GIS method, the spatial heterogeneity of soil fungal diversity in Stellera occurrence area and the spatial correlation between Stellera coverage and soil fungal diversity were investigated in a typical degraded alpine meadow of the Qilian Mountain. Compared to no-Stellera area, the fungi richness in Stellera area decreased, the dominance increased, and the α-diversity reduced.
