Design of integrated radar and communication system based on solvable chaotic signal.

In the integrated radar and communication system (IRCS), the design of signal that can simultaneously satisfy the radar detection and communication transmission is very important and difficult. Recently, some new properties of a class of solvable chaotic system have been studied for wireless applications, such as low bit error rate (BER) wireless communications and low cost target detection. In this paper, a novel IRCS based on the chaotic signal is proposed, and the performance of proposed scheme is analyzed.

Venetoclax plus D-CAG (decitabine, cytarabine, aclarubicin, G-CSF) for elderly or unfit patients with newly diagnosed acute myeloid leukemia: a multicenter, prospective study.

Induction regimens with satisfactory remission rates are limited for patients with acute myeloid leukemia (AML) who are elderly or ineligible for intensive chemotherapy. This study is a single-arm, multicenter, prospective phase I/II study (registered with the Chinese Clinical Trial Registry as ChiCTR 2200059694 on May 8, 2022), aiming to evaluate the efficacy and safety of venetoclax plus decitabine, cytarabine, aclarubicin, and granulocyte colony-stimulating factor (VD-CAG) for newly diagnosed AML patients who are elderly or ineligible for intensive chemotherapy. The primary endpoint was composite complete remission (CRc) after 1 cycle of induction chemotherapy.

Lipid droplets in pathogen infection and host immunity.

As the hub of cellular lipid metabolism, lipid droplets (LDs) have been linked to a variety of biological processes. During pathogen infection, the biogenesis, composition, and functions of LDs are tightly regulated. The accumulation of LDs has been described as a hallmark of pathogen infection and is thought to be driven by pathogens for their own benefit.

The order of multiple excited state proton transfer in ternary complex of norharmane and acetic acids.

Dolores Reyman et al. found the norharmane (9H-pyrido [3,4-b] indole) (NHM) and two acetic acid molecules can form the ternary complex (NHM-2A) in component solvent of dichloromethane and acetic acid via the hydrogen bond chain (J. Lumin.

The theoretical study of excited-state intramolecular proton transfer of 2,5-bis(benzoxazol-2-yl)thiophene-3,4-diol.

The symmetrical structures 2,5-bis(benzoxazol-2-yl)thiophene-3,4-diol (BBTD) can take shape two intramolecular hydrogen bonds in chloroform. In order to research the molecular dynamic behavior of BBTD upon photo-induced process, we utilize density functional theory (DFT) and time-dependent density functional theory (TDDFT) to complete theoretical calculation. Through the comparison of bond length, bond angle, IR spectra, and frontier molecular orbitals between ground state (S) and first excited state (S), it clearly indicates that photoexcitation have slightly influence for intensity of hydrogen bond.

Characterization of a dual-CRD galectin in the silkworm Bombyx mori.

Galectins (S-type lectins) are an ancient family of lectins with the β-galactoside binding activity. In mammals, galectins play essential roles in many biological processes, such as development, immune homeostasis and tumor progression. However, few studies have been devoted to their functions in insects.

Identification of C-type lectin-domain proteins (CTLDPs) in silkworm Bombyx mori.

C-type lectins (CTLs) represent a large family of proteins that can bind carbohydrate moieties normally in a calcium-dependent manner. CTLs play important roles in mediating cell adhesion and the recognition of pathogens in the immune system. In the present study, we have identified 23 CTL genes in domestic silkworm Bombyx mori.

Epidemiology and microbiology of sepsis in mainland China in the first decade of the 21st century.

Objectives: This study describes the epidemiological and microbiological profile of sepsis during the first decade of the 21(st) century in mainland China.

Methods: The sepsis-related mortality data from 2003 and 2007 were retrieved from the China Health Statistical Yearbook. The microbiology data were retrieved and selected from a literature search of the China Academic Journal Database between 2001 and 2009.

Reasons for exclusion of 6820 umbilical cord blood donations in a public cord blood bank.

Background: To provide information for umbilical cord blood (UCB) banks to adopt optimal collection strategies and to make UCB banks operate efficiently, we investigated the reasons for exclusion of UCB units in a 3-year recruitment period.

Study Design And Methods: We analyzed records of the reasons for exclusion of the potential UCB donation from 2004 to 2006 in the Tzu-Chi Cord Blood Bank and compared the results over 3 years. We grouped these reasons for exclusion into five phases, before collection, during delivery, before processing, during processing, and after freezing according to the time sequence and analyzed the reasons at each phase.

[Ageing down-modulates the immune responses to Schistosoma japonicum infection in mice].

Objective: To investigate the effect of ageing on the immune responses against Schistosoma japonicum infection in mice.

Methods: Female BALB/c mice were divided into young group (2 months) and old group (18 months), each composed of 8 mice. Each mouse was percutaneously infected with 40 +/- 1 S.
