Characteristics and Significance of Tertiary Lymphoid Structures Based on Molecular Subtypes in Endometrial Cancer.

The purpose of this study is to investigate the characteristics and significance of tertiary lymphoid structures (TLSs) in endometrial cancer (EC) based on molecular subtypes. A total of 220 patients with EC were retrospectively enrolled, including 20 with polymerase epsilon ultramutated (POLE-mut), 63 with mismatch repair deficient, 32 with p53 abnormal, and 105 with no specific molecular profile. The presence and maturity of TLSs were determined by immunohistochemical markers (CD3, CD20, CD21, and Bcl6).

Mouse KL2 is a unique MTSE involved in chromosome-based spindle organization and regulated by multiple kinases during female meiosis.

Microtubule-severing enzymes (MTSEs) play important roles in mitosis and meiosis of the primitive organisms. However, no studies have assessed their roles in mammalian meiosis of females, whose abnormality accounts for over 80% of the cases of gamete-originated human reproductive disease. In the current study, we reported that katanin-like 2 (KL2) was the only MTSE concentrating at chromosomes.

NLRP4E regulates actin cap formation through SRC and CDC42 during oocyte meiosis.

Background: Members of the nucleotide-binding oligomerization domain, leucine rich repeat and pyrin domain containing (NLRP) family regulate various physiological and pathological processes. However, none have been shown to regulate actin cap formation or spindle translocation during the asymmetric division of oocyte meiosis I. NLRP4E has been reported as a candidate protein in female fertility, but its function is unknown.

Frequency regulated transmission-reflection integration modes of a terahertz metasurface.

The conventional transmission and reflection operating mode switching metasurface depends on phase change materials, which are often difficult to integrate with metasurface devices and work in real time. Here, we propose an integration of a transmission-reflection metasurface that can dynamically control beam direction and functions in both transmission and reflection modes by varying the frequency of the incident wave. Remarkably, the transmission and reflection modes of terahertz beam manipulation can be obtained by illuminating only the transmission side of the metasurface.

Willingness-to-Pay and Benefit-Cost Analysis of IPL for Rosacea Treatment: A Cross-Sectional Study in China.

Background: Intense pulsed light (IPL), as a therapeutic approach for rosacea, had advantage in removing erythema and telangiectasia and was gradually accepted by rosacea patients, but there have been few studies on economic evaluation of this therapy.

We will search all literature sources from the inception to the present.

Rh(III)-Catalyzed C-H Cyanation of 2-Indazole with -Cyano--phenyl--toluenesulfonamide.

A Rh(III)-catalyzed direct cyanation of 2-indazoles with -cyano--phenyl--toluenesulfonamide has been realized via a chelation-assisted strategy. The methodology enables regioselective access to various ortho-cyanated phenylindazoles in good yields with a broad substrate scope and good functional group compatibility. The obtained cyanated indazoles could further be converted into other value-added chemicals.

The Influence of Hyperlipidemia on Endothelial Function of FPN1 Tek-Cre Mice and the Intervention Effect of Tetramethylpyrazine.

Background/aims: Systemic iron homeostasis is strictly governed in mammals; however, disordered iron metabolism (such as excess iron burden) is recognized as a risk factor for various types of diseases including AS (Atherosclerosis). The hepcidin-ferroportin axis plays the key role in regulation of iron homeostasis and modulation of this signaling could be a potential therapeutic strategy in the treatment of these diseases. TMP (Tetramethylpyrazine) has been reported to have therapeutical effect on AS.

Roux-en-Y gastric bypass surgery suppresses hypothalamic PTP1B protein level and alleviates leptin resistance in obese rats.

The present study aimed to explore the effect of Roux-en-Y gastric bypass (RYGB) surgery on protein tyrosine phosphatase 1B (PTP1B) expression levels and leptin activity in hypothalami of obese rats. Obese rats induced by a high-fat diet (HFD) that underwent RYGB (n=11) or sham operation (SO, n=9), as well as an obese control cohort (Obese, n=10) and an additional normal-diet group (ND, n=10) were used. Food efficiency was measured at 8 weeks post-operation.

Background: Sleep disorders are still an important clinical problem after renal transplantation. Previous studies mainly focused on patients' sleep quality before kidney transplant.

Concerns of and coping strategies by parents of pediatric liver transplant recipients: a qualitative study from China.

Parents of liver transplant recipient children have to face complicated health issues of their children. Coping strategies of parents as major care providers not only impacts on their handling of stresses on themselves but also on the recipients' quality of life. In this study, we sought to investigate the coping strategies of parents of Chinese pediatric liver transplant recipients at a single tertiary care institution in China.

Downregulation of KDR expression induces apoptosis in breast cancer cells.

Angiogenesis plays a crucial role in the growth, invasion and metastasis of breast cancer. Vascular endothelial growth factors (VEGFs) and their receptors (VEGFRs) are the key regulators of tumor angiogenesis. VEGFR-2, known as the kinase insert domain receptor (KDR), is a key receptor involved in malignant angiogenesis.

[Effects of transient receptor potential V6 silence on proliferation and apoptosis of trophoblasts].

Objective: To investigate the effects of the transient receptor potential V6 (TRPV6) gene silencing on the proliferation and apoptosis of trophoblasts HTR-8/SVneo cells.

Methods: siRNA sequences targeting the TRPV6 gene were constructed and then transfected into HTR-8/SVneo cells mediated by liposome. The cells were divided three groups, including blank control (add the reagent of transfenction), negative control groups (transfecting nonspecific siRNA) and experimental groups (transfecting TRPV6-siRNA).

Reactive astrocytes contribute to increased epileptic susceptibility induced by subthreshold dose of pilocarpine.

Seizures may influence epileptogenesis, but it is not yet clearly established whether subthreshold stimulations that are not sufficient to induce visible behavioral seizures change epileptic susceptibility, and the possible underlying mechanisms have not been completely understood. We assessed the susceptibility to epilepsy after subthreshold dose of pilocarpine, as well as glial fibrillary acidic protein (GFAP) expression using immunohistochemistry. An increase in the susceptibility to pentylenetetrazole (PTZ)-induced seizures was observed in rats previously subjected to subthreshold dose of pilocarpine.

[Effect of safflor yellow B on vascular endothelial cells injury induced by angiotensin-II].

This study is to investigate protective effect of safflor yellow B (SYB) against vascular endothelial cells (VECs) injury induced by angiotensin-II (Ang-II). VECs were cultured and divided into six groups: control group, Ang-II group, Ang-II + SYB (1 micromolL(-1)) group, Ang-II + SYB (10 micromolL(-1)) group, Ang-II + SYB (100 micromolL(-1)) group and Ang- II + verapamil (10 micromolL(-1)) group. Except control group, all of VECs in other groups were treated with Ang- II at the final concentration of 0.

Poly[[μ-1,4-bis-(1H-imidazol-4-yl)benzene-κN:N](μ-5-methyl-isophthalato-κO:O)cobalt(II)].

In the title coordination polymer, [Co(C(9)H(6)O(4))(C(12)H(10)N(4))](n), the Co(II) atom is four-coordinated by two O atoms from two different 5-methyl-isophthalate bivalent anions and two N atoms from two different 1,4-bis-(1H-imidazol-4-yl)benzene ligands, forming a four-coordinated tetra-hedral coordination geometry. Each 5-methyl-isophthalate ligand acts as a μ(2)-bridge, linking two Co(II) atoms and forming chains which are further linked by 1,4-bis-(1H-imidazol-4-yl)benzene ligands into a two-dimensional network parallel to ([Formula: see text]01). These planes are, in turn, linked by two inter-molecular N-H⋯O inter-actions, forming a three-dimensional structure.
