Blunting the tumor's stress-sensing ability is an effective strategy for controlling tumor adaptive survival and metastasis. Here, we have designed a cyclically amplified nano-energy interference device based on lipid nanoparticles (LNP), focused on altering cellular energy metabolism. This innovative nano device efficiently targets and monitors the tumor's status while simultaneously inhibiting mitochondrial respiration, biogenesis and ribosome production.

Background: Biliary mucinous cystic neoplasms (BMCNs) are rare hepatobiliary cystic tumors, which can be divided into noninvasive and invasive types. This study aimed to investigate the diagnosis, treatment, and prognosis of BMCNs in a large single center.
Methods: We analyzed 49 patients with BMCNs confirmed by postoperative pathology at the First Affiliated Hospital, Zhejiang University School of Medicine between January 2007 and December 2021.
Long noncoding RNAs (lncRNAs) can compete with endogenous RNAs to modulate the gene expression and contribute to oncogenesis and tumor metastasis. lncRNA NKX2-1-AS1 (NKX2-1 antisense RNA 1) plays a pivotal role in cancer progression and metastasis; however, the contribution of aberrant expression of NKX2-1-AS1 and the mechanism by which it functions as a competing endogenous RNA (ceRNA) in gastric cancer (GC) remains elusive. NKX2-1-AS1 expression was detected in paired tumor and nontumor tissues of 178 GC patients by quantitative reverse transcription PCR (qRT-PCR).

Two large-scale outbreaks of streptococcal toxic shock-like syndrome in China suggest that the pathogenicity of has been changing in recent years. Genetic analysis revealed the presence of a chromosomal pathogenicity island (PAI) designated SsPI-1 in Chinese epidemic strains.

Herein, to overcome the limited tissue penetration in traditional PDT, a novel near-infrared (NIR) light-activated NaScF: 40% Yb, 2% Er@CaF upconversion nanoparticle (rUCNP) is successfully designed and synthesized. Chlorin e6, a photosensitizer and a chelating agent for Mn, is loaded into human serum albumin (HSA) that further conjugates onto rUCNPs.

However, the major challenge is how to establish an advanced nanoplatform that can be efficiently guided to tumor sites and can then stably release both chemotherapy drugs and a photosensitizer simultaneously and precisely. In this study, which considered the possibility and targeting efficiency of a magnetic targeting strategy, a novel FeO@mSiO(DOX)@HSA(Ce6) nanoplatform was successfully built; this platform could be employed as an efficient synergistic antitumor nanoplatform with magnetic guidance for highly specific targeting and retention.

Objective: This meta-analysis aimed to illustrate the efficacy and safety of preganalin for pain management in patients with postherpetic neuralgia (PHN).
Methods: In July 2017, a systematic computer-based search was conducted in PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, and Google database. Data on patients with PHN that compared pregabalin versus placebo were retrieved.
A feasible and scalable two-step method is developed to synthesize LiFeSO4F(y)(OH)(1-y) which could deliver 92 and 80 mA h g(-1) when cycled at 1 C and 15 C, respectively. Moreover, with 80% of capacity retention after 2800 cycles at 1 C, this material should be of great interest as a contender to LiFePO4 for use in high power Li-ion batteries.

Fe(3)O(4) was obtained by liquid-phase coprecipitation; HSA-coated magnetic particles were attained by solidification at high temperature. The result was that nanosized Fe(3)O(4) is a cubic crystal by XRD and the average size is 18.

Objective: To observe the physiological and biochemical effects of intermittent fasting combined with hunger-resistant food on mice, and to evaluate the safety and beneficial effects of this regimen.
Methods: One hundred and forty-four adult ICR mice were divided into 4 groups: standard feed AL group (ad libitum intake of standard feed), hunger-resistant food AL group (ad libitum intake of hunger-resistant food), standard feed IF group (feeding standard feed and fasting on alternate days), and hunger-resistant food IF group (feeding hunger-resistant food and fasting on alternate days). The experiment lasted for 4-8 weeks and all mice drank water freely.
Aim: To investigate the adhesive mechanical properties of different cell cycle human hepatoma cells (SMMC-7721) to human umbilical vein endothelial cells (ECV-304), expression of adhesive molecule integrinbeta1 in SMMC-7721 cells and its contribution to this adhesive course.
Methods: Adhesive force of SMMC-7721 cells to endothelial cells was measured using micropipette aspiration technique. Synchronous G1 and S phase SMMC-7721 cells were achieved by thymine-2-deoxyriboside and colchicines sequential blockage method and double thymine-2-deoxyriboside blockage method, respectively.
