Lithium metal anode has attracted wide attention due to its ultrahigh theoretical specific capacity, lowest reduction potential, and low density. However, uncontrollable dendritic growth and volume change caused by uneven Li deposition still seriously hinder the large-scale commercial application of lithium metal batteries, even causing serious battery explosions and other safety problems. Hence, gold nanoparticles with a gradient distribution anchored on 3D carbon fiber paper (CP) current collectors followed by the encapsulation of polydopamine (PDA) (CP/Au/PDA) are constructed for stable and dendrite-free Li metal anodes for the first time.

Univariable and multivariable Cox regression models were used to predict the association of baseline NLR as a dichotomous variable with PFS and OS after chemotherapy initiation.

In this study, an eco-friendly subcritical water method was used to extract pectin from waste jackfruit peel (JFP-S), which was compared with pectin obtained by the traditional citric acid method (JFP-C).
Results: The extraction process was optimized using response surface methodology (RSM), and the optimum process parameters were as follows: extraction temperature 138 °C, extraction time 9.
Background: The clinical value of thymus preservation during thyroid carcinoma surgery remains unclear. The aim of this study is to explore the role of bilateral thymus preservation in parathyroid glands (PGs) function and surgical completeness in total thyroidectomy (TT) with bilateral central lymph node dissection (CLND).
Materials And Methods: Fifty-four consecutive patients who underwent TT and bilateral CLND were assigned to the thymus preservation (TP) group (n = 27) and the bilateral thymectomy (BT) group (n = 27).
Although graphene-based thermal interface materials (TIMs) have great potentials in removing excess heat generated during highly efficient running of electronic devices, their practical applications are usually limited by their unsatisfactory thermal conductions, which are mainly caused by unsatisfactory dispersion and distribution, low loading, and low quality of graphene sheets, as well as the thermal interfacial resistance between graphene sheets and polymer matrix. Herein, we develop vertically aligned graphene hybrid foams (GHFs) with high densities by hydrothermal reduction of graphene oxide in the presence of high-quality graphene nanoplatelets (GNPs) followed by air-drying. The reduced graphene oxide sheets play an important role in constructing a vertically aligned interconnection network for accommodating GNPs during the hydrothermal reduction process, while the incorporated GNPs not only make the thermal conductance network denser but also prevent excessive shrinkage of the foams during air-drying.

Methods: Seventy-two patients were randomly assigned to two groups: standard dissection and limited dissection. Postoperative pain and inflammatory response were compared between groups.
Aim: The aim of this study was to evaluate the issue of improvement of disadvantages of different type meshes.
Methods: A retrospective analysis was performed on 101 gastroesophageal reflux disease patients who underwent reinforcement of crura with or without prosthetic mesh. Three types of mesh, 4-ply biologic small intestine submucosa (SIS, Surgisis(®), since November 2010), 6-ply SIS (Biodesign™ Surgisis(®), since March 2011), and composite synthetic mesh (Crurasoft(®), since May 2010), were used.
Aim: To evaluate the efficacy of carbon nanoparticles (CNs) in identifying lymph nodes and preserving parathyroids in endoscopic total thyroidectomy (ETT) with central neck dissection (CND), and to further explore the role of CNs in recovering postoperative parathyroid function.
Method: Fifty-five patients with papillary thyroid carcinoma were randomized to either CN group (n = 28) or control group (n = 27). The primary outcome measures were pathological results (e.
A simple and inexpensive aqueous two-phase affinity partitioning system using metal ligands was introduced to improve the selectivity of commercial papain extraction. Polyethylene glycol 4000 was first activated using epichlorohydrin, then it was covalently linked to iminodiacetic acid. Finally, the specific metal ligand Cu(2+) was attached to the polyethylene glycol-iminodiacetic acid.

Methods: Twenty-one patients underwent HH repair with Crurasoft® reinforcement. Gastroesophageal reflux disease (GERD) and HH-related symptoms including heartburn, regurgitation, chest pain, dysphagia, and abdominal pain were evaluated preoperatively and 6 mo postoperatively.
A facile and efficient approach was developed to simultaneously functionalize and reduce graphene oxide (GO) with p-phenylene diamine (PPD) by simple refluxing. This was possible by the nucleophilic substitution reaction of epoxide groups of GO with amine groups of PPD aided by NH(3) solution. As a consequence, electrical conductivity of GO-PPD increased to 2.

The objective of the present study was to compare surgical outcomes of SET performed by an experienced surgeon with the outcomes of conventional thyroidectomy.
Method: Enrolled in this study were 25 patients who underwent SET and 18 who underwent conventional surgery.
We evaluated the invasiveness of breast approach endoscopic thyroidectomy (BAET) carried out by surgeon very experienced in this procedure. Twenty-four patients who underwent BAET and 19 patients who underwent conventional thyroidectomy were the study population. Postoperative pain was assessed by a visual analog scale (VAS).

The repair of hair-occluded information is one of the key problems for the precise segmentation and analysis of the skin malignant melanoma image with hairs. Aimed at dermoscopy images of pigmented skin lesions, an unsupervised repair algorithm for the hair-occluded information is proposed in this paper. This algorithm includes three steps: first, the melanoma image with hairs are enhanced by morphologic closing-based top-hat operator and then segmented through statistic threshold; second, the hairs are extracted based on the elongate of connected region; third, the hair-occluded information is repaired by the PDE-based image inpainting.

However, whether osteoporotic SAMP6 mice have cognitive deficits remains largely unexplored. Here, we used Morris water maze to assess reference memory and working memory performance in SAMP6 mice and SAMR1 controls, at 4 and 8 months of age.
