Circular RNAs as Biomarkers in Breast Cancer Diagnosis, Prognosis, Molecular Types, Metastasis and Drug Resistance.

Breast cancer is one of the leading causes of cancer-related deaths in women worldwide. Circular RNAs (circRNAs), a novel class of endogenous noncoding RNA with a covalently closed continuous loop that lacks the 5'-cap structure and the 3'-poly A tail, are more stable than linear RNAs and less susceptible to degradation by nucleases. CircRNAs are widespread in multiple mammalian genomes and have been detected in various tissues, cells and body fluids.

Background: Epidemiological studies have reported that polymorphisms of folate-metabolizing genes have a significant impact on male infertility. However, the results of published studies have come to different conclusions.

Objective: To determine an association between folate-metabolizing gene polymorphisms and the risk of male infertility.

Multiway Junction Conditions for Spacetimes with Multiple Boundaries.

We explore the construction of gluing together an arbitrary number of spacetimes along a common interface. This provides a general tool to construct new gravitational backgrounds with multiple boundaries. We derive junction conditions across the interface, in both Einstein gravity and dilaton gravity, using two methods (1) by developing a geometrical technique of introducing an auxiliary reverse extension manifold and (2) by the variational principle.

Photoinduced Palladium-Catalyzed 1,2-Aminoalkylation of Aromatic Alkenes with Hydroxyl as the Directing Group.

The hybrid nature of Pd(I)-alkyl radical species has enabled a wide array of radical-based transformations. However, in this transformation, the secondary Pd(I)-alkyl radical species are prone to recombining into Pd(II)-alkyl species to give Heck-type products via β-H loss. Herein, we report a visible-light-induced, three-component Pd-catalyzed 1,2-aminoalkylation of alkenes with readily available alkyl halides and amines to construct C-C and C-N bonds simultaneously.

Impact of insulin resistance on IVF/ICSI outcomes in women with polycystic ovary syndrome: A systematic review and meta-analysis.

Objective: To evaluate the effect of insulin resistance (IR) on in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes in patients with polycystic ovary syndrome (PCOS).

Study Design: PubMed, Google Scholar,Web of Science, Embase, Scopus and the Cochrane Library were searched to identify relevant studies. A total of 6,137 PCOS women undergoing IVF/ICSI with or without IR were included in the systematic review and meta-analysis.

Photoredox/Copper-Catalyzed One-Pot Aminoalkylation/Cyclization of Alkenes with Primary Amines to Synthesize Polysubstituted γ-Lactams.

Visible-light-driven chemical transformation has emerged as a powerful tool for the synthesis of γ-lactams. However, during this transformation, the α-bromoimides need to be pre-prepared. Herein, we report a photoreodox/copper-catalyzed one-pot three-component reaction of alkenes with primary amines for the construction of γ-lactams.

Leukocyte immunoglobulin-like receptor A3 gene deletion in five Chinese populations and protective association with nasopharyngeal carcinoma.

Among the thirteen leukocyte Ig-like receptor (LILR) loci located at 19q13.4, LILRA3 is unique in that it encodes a soluble protein lacking the transmembrane and cytoplasmic domains, and a 6.7 kb deletion spanning the first seven exons has been detected in some human individuals.

[Determination of catecholamines in urine by disperse solid-phase extraction-liquid chromatography based on TiCT/polyimide composites].

Neurotransmitters (NTs) are basic signaling chemicals used for communication between cells. The most well-known catecholamines (CAs) are epinephrine, norepinephrine, and dopamine. CAs are an important class of monoamine NTs that contain catechins and amine groups.

TPX2 enhances the transcription factor activation of PXR and enhances the resistance of hepatocellular carcinoma cells to antitumor drugs.

The pregnane X receptor (PXR) is an important regulator of hepatocellular carcinoma cellular resistance to antitumor drugs. Activation of PXR was modulated by the co-regulators. The target protein for the Xenopus plus end-directed kinesin-like protein (Xklp2) known as TPX2 that was previously considered as a tubulin regulator, also functions as the regulator of some transcription factors and pro-oncogenes in human malignances.

Sanguinarine, identified as a natural alkaloid LSD1 inhibitor, suppresses lung cancer cell growth and migration.

Objectives: Lysine-specific demethylase1 (LSD1), an important class of histone demethylases, plays a crucial role in regulation of mammalian biology. The up-regulated LSD1 expression was frequently associated with progress and oncogenesis of multiple human cancers, including non-small cell lung cancer (NSCLC). Therefore, inhibition of LSD1 may provide an attractive strategy for cancer treatment.

The Combination of AFP and "Up-To-Seven" Criteria May Be a Better Strategy for Liver Transplantation in Chinese Cirrhotic HCC Patients.

Background: Orthotopic liver transplantation (OLT) is a life-saving option for patients with hepatocellular carcinoma (HCC), but the expanded OLT criteria remain controversial.

Objective: The study aimed to explore whether expanded OLT criteria can be applied to Chinese cirrhotic patients with HCC.

Methods: This retrospective study analyzed risk factors for HCC recurrence and death and compared patients' tumor characteristics and outcomes in groups of Milan, "Up-to-seven," and Hangzhou criteria, and groups between met and unmet the combinative criteria of "Up-to-seven" and AFP of < 1000 ng/mL.

Orthodontic treatment combined with 3D printing guide plate implant restoration for edentulism and its influence on mastication and phonic function.

Background: Dentition defect, a common clinical oral disease developed in humans, not only causes masticatory dysfunction and articulation difficulties but also affects facial appearance and increases the burden on the intestinal tract. Restorative treatment is the primary option for this disease. However, traditional restorations have many drawbacks, such as mismatch with the body, low reliability, and incomplete occlusal function recovery.

Judgement of the Clinical Value of Spiral CT Three-Dimensional Reconstruction in the Diagnosis of Lumbar Degenerative Osteoporosis.

With the aging of the population, there are more and more degenerative diseases of the lumbar spine that accompany osteoporosis. Lumbar degenerative osteoporosis has also become fragile and high in incidence, which has also attracted the attention of experts and scientists in related fields. Degeneration of the lumbar spine often causes pain in the waist and surrounding patients and even affects their life safety.

L4-to-L4 nerve root transfer for hindlimb hemiplegia after hypertensive intracerebral hemorrhage.

There is no effective treatment for hemiplegia after hypertensive intracerebral hemorrhage. Considering that the branches of L4 nerve roots in the lumbar plexus root control the movement of the lower extremity anterior and posterior muscles, we investigated a potential method of nerve repair using the L4 nerve roots. Rat models of hindlimb hemiplegia after a hypertensive intracerebral hemorrhage were established by injecting autogenous blood into the posterior limb of internal capsule.

Sex-Specific Neurotoxicity of Dietary Advanced Glycation End Products in APP/PS1 Mice and Protective Roles of Trehalose by Inhibiting Tau Phosphorylation via GSK-3β-TFEB.

Scope: It remains unclear whether dietary advanced glycation end products (dAGEs)-induced cognitive impairment is sex-dependent. Trehalose may antagonize dAGEs-induced neurotoxicity via glycogen synthase kinase-3 beta (GSK3β)-transcription factor EB (TFEB) signaling.

Methods And Results: The sex-specific neurotoxicity of dAGEs and the protective role of trehalose are investigated both in vivo and in vitro.
