Objective: To report a novel mutation in GHR and to characterize a novel mechanism of nonclassical growth hormone insensitivity.
Context: Laron syndrome (LS) is a well-described disorder of growth hormone insensitivity due to mutations in the growth hormone receptor (GHR) that leads to short stature. Biochemically, LS patients classically have elevated levels of growth hormone (GH), but low levels of insulin-like growth factor (IGF)-1, IGF binding protein (IGFBP)-3 and GH binding protein (GHBP).

Purpose: The purpose of this study was to investigate the efficacy of microvascular coupler for arterial anastomosis in head and neck reconstruction during a 2-year period at the Department of Oral and Maxillofacial Surgery, Shandong Provincial Hospital.
Methods: Twenty-one cases of microvascular free flaps from October 2013 through December 2014 were retrospectively reviewed. Flap survival and thrombosis of the arterial anastomoses were determined in these cases.
Background: Head and neck squamous cell carcinoma (HNSCC) is a disastrous disease with substantial morbidity and mortality. This study aims to explore the effective diagnostic and prognostic biomarkers for HNSCC.

Efficient strategies in enhancing sensitivity are pivotal to ultrasensitive detection of tumor markers. In this work, based on the strategy of label-assisted chemical adsorption triggered conversion of electroactivity of sensing interface, a Ag/AgCl process was achieved to enhance sensitivity of the constructed sandwich-type amperometric immunosensor for ultrasensitive detection of carbohydrate antigen 19-9 (CA19-9). Briefly, polydopamine-Ag nanoparticles (PDA-Ag NPs), as signal precursor, combined with labeling antibody were served as labels and graphene oxide-melamine (GO-MA) substrate with chemical absorption capacity was applied as smart sensing interface.

The interest in deep-sea mining increased along with the environmental concerns of these activities to the deep-sea fauna. The discovery of optimal biomarkers of deep-sea mining activities in deep-sea species is a crucial step toward the supply of important ecological information for environmental impact assessment. In this study, an in situ copper exposure experiment was performed on deep-sea scavenging amphipods.

In this work, a promising therapy for tumor treatment that can eliminate primary tumors and prevent tumor relapses is introduced by combining chemotherapy, photothermal therapy (PTT) and immunotherapy. Multifunctional FePt/MoS-FA nanocomposites (FPMF NCs) were obtained via anchoring FePt nanoparticles and folic acid (FA) on MoS nanosheets.

In this work, an acidity-sensitive nanotheranostic agent (FePt@MnO)@DSPE-PEG5000-FA (FMDF NPs) was successfully constructed for MR imaging guided ferroptosis chemodynamic therapy (FCDT) of cancer. The FMDF NPs could specifically target folic acid (FA) receptor-positive tumor cells (HeLa etc.

A search of electronic databases and a manual search was performed for the time period January 2000 to April 2018. A meta-regression was used to evaluate the effects of the "fixed effects" model on the implant survival rates, prosthesis success rates and marginal bone loss (MBL) with follow-up time of 1 year and 3 years.

Here, we designed a dual-modality US/NIRF contrast agent and extended its applications from image contrast enhancement to combined diagnosis and therapy with US-directed and site-specific targeting.
Methods: Gold nanorods (AuNRs) resonant at 880 nm together with the NIR797 dye were first encapsulated in lipid-shelled MBs to construct fluorescent gold microbubbles (NIR797/AuMBs) via thin film hydration and mechanical shaking in the presence of sulfur hexafluoride (SF) gas.

Background: Many studies have found volume changes in the hippocampus and amygdala in patients with schizophrenia, but these findings have not reached an agreement. Particularly, few results showed the volumes of the sub-regions of the amygdala. In this research, we aim to clarify volume changes of hippocampus and amygdala sub-regions in patients with schizophrenia.

To explore the underlying molecular regulation of non-coding RNA for HCC, differentially expressed patterns of lncRNAs and genes were examined by RNA-seq. GO and KEGG pathway analysis were done based on the function of mRNAs that mediated by differentially expressed lncRNAs.

Background: Rib fractures account for a fairly high proportion of chest injuries, ranging from 55 to 80%. The most common mechanisms of injury include: traffic accident, extrusion and falls from significant heights. Besides, the surgical treatment of multiple rib fractures has been accepted by more and more medical professionals.

Efficient signal amplification strategies are crucial for ultrasensitive detection of tumor markers. Herein, a new signal amplification strategy by coupling cascade catalysis-initiated radical polymerization with impedimetric immunoassay was proposed for ultrasensitive detection of carbohydrate antigen 15-3 (CA15-3). Copper-based metal-organic framework nanoparticles (Cu-MOF), as peroxidase mimics, combined with CA15-3 antibody (Ab) and glucose oxidase (GOx) were employed as immunoprobes to initiate radical polymerization by cascade catalysis.
