A comparison of the effects of two protocols of concurrent resistance and aerobic training on physical fitness in middle school students.

Objective: This study aimed to compare the effects of two concurrent training (CT) protocols on the physical fitness of middle school students.

Method: A 12-week quasi-experimental pre-test/post-test study was conducted with 157 middle school students (age = 12.48 ± 0.

Complete response in patient with liver metastasis of HER2-positive breast cancer following therapy with margetuximab: a case report.

Metastatic human epidermal growth factor receptor 2 (HER2) positive breast cancer has a poor prognosis and few effective targeted therapies. However, several anti-HER2 agents are emerging in conjunction with chemotherapy, which may lead to increased rates of pathological complete response in patients with HER2-positive metastatic breast cancer. Among them, margetuximab demonstrated a significant improvement in progression-free survival compared with trastuzumab, when combined with chemotherapy in pretreated patients.

Prognostic Value of Preoperative Controlling Nutritional Status in Hypopharyngeal Cancer Patients Undergoing Surgery-Oriented Comprehensive Treatment.

Objectives: The preoperative controlling nutritional status (pCONUT) score has been shown correlated with the prognosis of some cancerous diseases; however, little is known about the effect of pCONUT score on hypopharyngeal cancer (HPC). Therefore, the objective of our study was to demonstrate the relationship between the pCONUT score and the clinical outcome of patients with HPC.

Patients And Methods: Ninety-four patients with HPC who underwent surgery between May 2012 and Dec 2020 were enrolled in this study.

Melting of recycled ancient crust responsible for the Gutenberg discontinuity.

A discontinuity in the seismic velocity associated with the lithosphere-asthenosphere interface, known as the Gutenberg discontinuity, is enigmatic in its origin. While partial mantle melts are frequently suggested to explain this discontinuity, it is not well known which factors critically regulate the melt production. Here, we report geochemical evidence showing that the melt fractions in the lithosphere-asthenosphere boundary were enhanced not only by accumulation of compacted carbonated melts related to recycled ancient marine sediments, but also by partial melting of a pyroxene-rich mantle domain related to the recycled oceanic eclogite/pyroxenites.

Review of antidepressants in clinic and active ingredients of traditional Chinese medicine targeting 5-HT1A receptors.

Serotonin, which also named as 5-hydroxytryptamine (5-HT), is a neurotransmitter, which plays significant roles in a wide range of physiological and pathological processes. Depression is a complex disease that involves numerous factors, increasing evidences have showed that the level of 5-HT was lower in depressed patients and the administration of some selective serotonin re-uptake inhibitors exhibited antidepressant effects. The 5-HT1A receptor is a key protein in the brain serotonin system, modulating the release of 5-HT and other neurotransmitters.

[Research advances on the pollution of pharmaceutical and personal care products (PPCPs) in natural waters and their toxicity to freshwater algae.].

The continuous discharge of pharmaceutical and personal care products (PPCPs) into aquatic environment and their potential threaten to ecological environment or human health has received more and more attention all over the world. Algae are primary producers in aquatic environment and play an important role in ecosystem balance and stabilization. In this review, the concentrations of PPCPs in natural waters from different countries and regions are introduced to demonstrate their characteristics of pollution in aquatic environment.

Monolayer β-tellurene: a promising p-type thermoelectric material via first-principles calculations.

Inspired by the experimental growth of two-dimensional (2D) tellurene (Yixin et al., Nat. Electron, 2018, 1, 228-236) and the recent study of unusually low thermal conductivity of atomically thin 2D tellurium (Jie Ren et al.

[Effective components of traditional Chinese medicine for regulating TGF-Beta1/Smads signaling pathway in hepatic fibrosis].

Hepatic fibrosis is a liver damage healing response affected by a variety of factors; its formation is associated with multiple cytokines and a variety of signaling pathways. Transforming growth factor beta1( TGF-β1) is one of the strongest fibrosis cytokines known,and involves almost all the key links in hepatic fibrosis. TGF-β1/Smads signal pathway is the most classical pathway for TGF-β1 to play its role in promoting fibrosis as well as one of the most important signaling pathways of hepatic fibrosis formation.

Recording, erasing, and rewriting of ripples on metal surfaces by ultrashort laser pulses.

Recording, erasing, and rewriting of ripples are achieved by applying femtosecond laser pulses on tungsten surfaces. Ripples oriented perpendicular to the polarization direction of the writing beam can be recorded on a metal surface by exposing the sample to a series of linearly polarized pulses. When applying the second series of pulses with varied polarization direction on the same place, the original ripples can be erased, and new ripples are rewritten with the orientation perpendicular to the polarization of the second group of pulses.

Bioconjugates of Glucose Oxidase and Gold Nanorods Based on Electrostatic Interaction with Enhanced Thermostability.

Bioconjugates made up of an enzyme and gold nanorods (GNRs) were fabricated by electrostatic interactions (layer-by-layer method, LBL) between anionic glucose oxidase (GOD) and positively charged GNRs. The assembled processes were monitored by UV-Vis spectra, zeta potential measurements, and transmission electron microscopy. The enzyme activity assays of the obtained bioconjugates display a relatively enhanced thermostability behavior in contrast with that of free enzyme.
