Association of Circulating Homocysteine Level with the Risk of Nephropathy in Type 2 Diabetes Mellitus: A Meta-Analysis.

The objective of the study was to explore the association between homocysteine (Hcy) levels and the risk of type 2 diabetic nephropathy (T2DN). PubMed, Web of Science, Cochrane Library, and Embase databases were searched to collect literature on the association between Hcy levels and the risk of T2DN. The retrieval period was from the establishment of the database to September 10, 2024.

Diagnosis, treatment, and misdiagnosis analysis of 28 cases of central nervous system echinococcosis.

Background: To explore central nervous system (CNS) involvement in this disease, from the perspectives of diagnosis, treatment, and misdiagnosis METHODS: Twenty-eight patients with CNS echinococcosis were included in this retrospective study, including 18 males (64.3%) and 10 (35.7%) females.

Identification of potential key pathways, genes and circulating markers in the development of intracranial aneurysm based on weighted gene co-expression network analysis.

Intracranial aneurysm (IA) is a disease resulted from weak brain control, characterized by local expansion or dilation of brain artery. This study aimed to construct a gene co-expression network by Weighted Gene Correlation Network Analysis (WGCNA) to explore the potential key pathways and genes for the development of IA. Six IA-related gene expression data sets were downloaded from the Gene Expression Omnibus (GEO) database for identifying differentially expressed genes (DEGs).

Mid-wave and long-wave infrared dual-band stacked metamaterial absorber for broadband with high refractive index sensitivity.

A dual-band metamaterial absorber based on local surface plasmon resonance is designed, which is composed of a periodic arrangement of stacked nanodisk structures. The structure unit consists of two dielectric layers and three metal layers. Based on the finite difference time domain method, under the condition of vertically incident plane light, two absorption peaks in the mid-wave infrared and long-wave infrared (MWIR/LWIR) are obtained, and the absorption is greater than 98%.

Small-sized long wavelength infrared absorber with perfect ultra-broadband absorptivity.

Two types of ultra-broadband long wavelength infrared (LWIR) absorbers with small period and super thin thickness are designed. The absorption with high absorptivity and large bandwidth is achieved through combined propagating and localized surfaced plasmon resonances. We first design a three-layer absorber with a Ti-Ge-Ti configuration, the period of the structure is only 1.

LncRNA XIST depletion prevents cancer progression in invasive pituitary neuroendocrine tumor by inhibiting bFGF via upregulation of microRNA-424-5p.

Background: Long noncoding RNAs (lncRNAs) are vital mediators in human cancers including pituitary neuroendocrine tumor (PitNET) and could function as competing endogenous RNAs (ceRNAs) of microRNAs (miRNAs). The main objective of this study is to identify effect of lncRNA X-inactive specific transcript (XIST) and microRNA-424-5p (miR-424-5p) on PitNET.

Methods: Microarray analysis was employed to identify the PitNET-related differentially expressed lncRNAs.

Short-term efficacy of pipeline embolization device for treating complex intracranial aneurysms.

Objective: To observe the short-term efficacy of Pipeline embolization divice (PED) for the treatment of complex intracranial aneurysms.

Methods: The clinical data of 29 consecutive patients with 32 intracranial aneurysms treated with PED between April 2015 to September 2016 were analyzed retrospectively. There were 3 small aneurysm, 15 large aneurysms, 8 giant aneurysms, 5 fusiform ayneurysms and 1 recidivation.

siRNA-mediated silencing of bFGF gene inhibits the proliferation, migration, and invasion of human pituitary adenoma cells.

Human pituitary adenoma is one of the most common intracranial tumors with an incidence as high as 16.7%. Recent evidence has hinted a relationship between growth factors of pituitary or hypothalamic origin and proliferation of human pituitary adenoma cells.

MicroRNA-145 inhibits the activation of the mTOR signaling pathway to suppress the proliferation and invasion of invasive pituitary adenoma cells by targeting AKT3 in vivo and in vitro.

Purpose: This study was designed to explore how miR-145 regulates the mTOR signaling pathway in invasive pituitary adenoma (IPA) by targeting AKT3.

Methods: A total of 71 cases of IPA tissues and 66 cases of non-IPA tissues were obtained in this study. In vitro, the IPA cells were assigned into blank control, empty plasmid, miR-145 mimic, miR-145 inhibitor, miR-145 mimic + rapamycin, miR-145 inhibitor + rapamycin and rapamycin groups.

MicroRNA-106b promotes pituitary tumor cell proliferation and invasion through PI3K/AKT signaling pathway by targeting PTEN.

The purpose of this study was to investigate the expression of microRNA-106b (miR-106b) and phosphatase and tensin homolog deleted on chromosome 10 (PTEN) in pituitary tumor and to confirm whether miR-106b promotes proliferation and invasion of pituitary tumor cells through the PI3K/AKT signaling pathway by targeted regulation of PTEN expression, and thereby to find new targets for the treatment of pituitary tumor. Fifty-five cases of pituitary tumor tissue samples were collected, including 29 cases of invasive pituitary tumor, non-invasive 26 cases, and 8 normal pituitaries. The expression level of miR-106b in pituitary tumor tissue was detected by quantitative real-time PCR, and the expression of PTEN protein was detected by immunohistochemistry.

Comparison of administration routes for adipose-derived stem cells in the treatment of middle cerebral artery occlusion in rats.

Given that adult adipose tissue is an abundant, accessible and safe source of stem cells, the use of adipose-derived stem cells (ADSCs) provides a promising approach in ischemic stroke. The delivery route, however, for transplantation of ADSCs in clinical application remains controversial regarding the time window, cell type, safety issues, 'first pass' effect and therapeutic effect. To determine the optimal administration route in transplantation of ADSCs, we compared the therapeutic effect of the three mainly used administration routes of ADSCs in a middle cerebral artery occlusion (MCAO) rat model.
