Renal cell carcinoma (RCC) is a malignant tumor originating from the epithelial cells of the renal tubules. The clear cell RCC subtype is closely linked to a poor prognosis due to its rapid progression. Circular RNA (circRNA) is a novel class of regulatory RNA molecules that play a role in the development of ccRCC, although their functions have not been fully elucidated.

In the current study, we evaluated the prevalence of sleep problems in preschool-aged children with ASD and to examine the correlations between sleep disturbances and emotional/behavioral symptoms and repetitive behavior in the unique social context of China. This study recruited 475 preschool-aged children aged 3-6 years old, including 252 children with ASD (mean age 5.

This study examined those relationships in Chinese preschool children with ASD using a case-control design. Atypical sensory processing was associated with increased risks of sleep disturbances, emotional and behavioral problems, and abnormal mealtime behaviors in the children with ASD, whereas sensory processing problems were significantly correlated with abnormal mealtime behaviors only in the typically developing children.

PAMAM dendrimer is one of the most widely studied dendrimers in recent years, which has a large number of functional groups on the surface and cavities inside, specific three-dimensional structure and good biocompatibility, permeability and stability. It has been widely applied in drug and gene carrier fields and may become a new absorption enhancer. In order to study the absorption enhancing effects of PAMAM dendrimers, liquiritin was selected as the model drug, with the protection of spleen and liver, detoxification and other functions, but it had not been widely used in clinical application because of its difficult absorption, first pass effect, and low bioavailability.

Methods: A case-control study was conducted through a questionnaire with 108 ASD cases, 79 ID cases, and 108 controls. The ASD and ID cases were students from special educational schools in Tianjin from 2012 to 2014.
Retinoid-related orphan receptor α (RORα), a member of the metabolic nuclear receptor superfamily, plays a vital regulatory role in circadian rhythm and metabolism. Here, we investigated the role of RORα in high-fat diet (HFD)-induced cardiac impairments and the underlying mechanisms involved. RORα-deficient stagger mice (sg/sg) and wild type (WT) littermates were fed with either standard diet or HFD.

The purpose of this study was to compare the effect of GLP-1 and placebo/conventional antidiabetic agents on cardiovascular risk in T2DM patients. PubMed, EmBase and the Cochrane Library were searched to identify its eligible studies as well as manual searches for the reliability of this study.

In this study, the effects of SiNPs on hemocytes and hematopoiesis were investigated by administering SiNPs via a vascular injection into an invertebrate model, the silkworm. Our results show that the ability of SiNPs to enter different types of circulating hemocytes and their impact on those hemocytes differed significantly.

However, little is known about the role of another ubiquitin proteasome system component, the deubiquitinating enzymes, in cardiac hypertrophy. Here, we revealed a crucial role of ubiquitin specific protease 4 (USP4), a deubiquitinating enzyme prominently expressed in the heart, in attenuating pathological cardiac hypertrophy and dysfunction.

Methods: A case-control study was conducted among 193 children with autism from the special educational schools and 733 typical development controls matched by age and gender by using questionnaire in Tianjin from 2007 to 2012. Statistical analysis included quick unbiased efficient statistical tree (QUEST) and logistic regression in SPSS 20.
Autism spectrum disorder (ASD) is a neurological disorder that presents a spectrum of qualitative impairments in social interaction, communication, as well as restricted and stereotyped behavioral patterns, interests, and activities. Several studies have suggested that the etiology of ASD can be partly explained by oxidative stress. However, the implications of abnormal transsulfuration metabolism and oxidative stress, and their relation with ASD are still unclear.

This study investigates the effects of stimulus rate on the recording efficiency of evoked-response scenario using a computer generated data simulating auditory evoked potentials (AEPs). We examine AEPs derived from three paradigms: 1) Conventional stimuli for ensemble averaging; 2) continuous loop averaging deconvolution (CLAD); and 3) maximum length sequence (MLS) stimuli, in which deconvolution techniques are incorporated to retrieve the overlapped responses. The performance is evaluated by correlation coefficients between the ideal and the derived responses.
