Application of norepinephrine in the treatment of septic shock: a meta-analysis.

Objective: To systematically evaluate the efficacy and safety of norepinephrine in the treatment of septic shock.

Methods: Literature retrieval of eligible randomized controlled trials (RCTs) on norepinephrine in the treatment of septic shock was performed in three English databases including PubMed, Web of Science, and Medline from database establishment to October 1, 2023. The Cochrane risk bias tool was used to evaluate the quality of the included literature.

Knockdown of inhibits Akt/β-catenin-mediated cell invasion and migration in clear cell renal cell carcinoma cells.

The gene encoding lamin A/C is amplified in some clear cell renal cell carcinoma (ccRCC) samples. Our data showed that depletion of the tumor suppressor PBRM1 can upregulate lamin A/C levels, and lamin A/C could interact with PBRM1. However, the role of lamin A/C in ccRCC is not yet fully understood.

Dual-linear chirp microwave signal generation by using single-beam injection to a DFB semiconductor laser and optical heterodyne technique.

Based on a single-beam injection distributed feedback semiconductor laser (DFB-SL) combining with optical heterodyne, a photonic scheme for generating dual-linear chirp microwave (dual-LCM) signal with identical or complementary chirp is proposed and experimentally demonstrated. For such a scheme, a continuous-wave (CW) light with a frequency of finj is split into two parts. One part is passing through a Mach-Zehnder modulator (MZM) driven by a modified sawtooth signal, and then its intensity varies with time as a sawtooth wave.

PBRM1 deficiency oncogenic addiction is associated with activated AKT-mTOR signalling and aerobic glycolysis in clear cell renal cell carcinoma cells.

The PBRM1 (PB1) gene which encodes the specific subunit BAF180 of the PBAF SWI/SNF complex, is highly mutated (~ 40%) in clear cell renal cell carcinoma (ccRCC). However, its functions and impact on cell signalling are still not fully understood. Aerobic glycolysis, also known as the 'Warburg Effect', is a hallmark of cancer, whether PB1 is involved in this metabolic shift in clear cell renal cell carcinoma remains unclear.

High-quality frequency-modulated continuous-wave generation based on a semiconductor laser subject to cascade-modulated optical injection.

Frequency-modulated continuous-wave (FMCW) can be acquired by using a distributed feedback semiconductor laser (DFB-SL) operating at period-one (P1) oscillation under an optical injection modulated by a Mach-Zehnder modulator (MZM). In this work, through introducing another MZM to establish cascade-modulated optical injection, an improved photonic scheme for generating high-quality FMCW is proposed and experimentally demonstrated. The experimental results indicate that, under appropriate injection parameters, the central frequency of the generated FMCW is widely tunable, and the bandwidth is larger than that obtained under a single MZM modulation.

Objective: To study the impact of anticoagulant to the quality of umbilical cord blood (UCB).

Methods: 6060 cord blood units (CBUs) were classified into five groups, such as 28 ml: (10-29) ml, 28 ml: (30-69) ml, 28 ml: (70-109) ml, 28 ml: (110-150) ml and 28 ml: (>150) ml according to volume ratio of anticoagulant and CBVs. The count of pre-cryopreservation total nucleated cell (pre-TNC), the viability of nucleated cell (VNC), the amount of CFU-GM and the ratio changes of CD34 were evaluated and analyzed statistically.

Performance optimization research of reservoir computing system based on an optical feedback semiconductor laser under electrical information injection.

Via Santa Fe time series prediction and nonlinear channel equalization tasks, the performances of a reservoir computing (RC) system based on an optical feedback semiconductor laser (SL) under electrical information injection are numerically investigated. The simulated results show that the feedback delay time and strength seriously affect the performances of this RC system. By adopting a current-related optimized feedback delay time and strength, the RC can achieve a good performance for an SL biased within a wide region of 1.
