Tumor heterogeneity and tumor evolution contribute to cancer treatment failure. To understand how selective pressures drive heterogeneous tumor evolution, it would be useful to image multiple important components and tumor subclones in vivo. We propose a supercontinuum-tailoring two-photon microscope (SCT-TPM) and realize simultaneous observation of nine fluorophores with a single light beam, breaking through the 'color barrier' of intravital two-photon fluorescence imaging.

While the hindbrain is pivotal in fundamental biological functions, its role in modulating emotions has been underappreciated. This review will uncover critical targets and circuits within the hindbrain that are essential for both anxiety and anxiolytic effects, expanding on research obtained through behavioral tests.

Objectives: This study investigated the safety and timing of prophylactic heparin for VTE in patients with sICH.
During the COVID-19 outbreak, there was a sharp increase in generalized anxiety disorder (GAD). Acupuncture therapy has the advantages of accurate clinical efficacy, safety and reliability, few adverse reactions, and no dependence, and is gradually becoming one of the emerging therapies for treating GAD. We present a study protocol for a randomized clinical trial with the aim of exploring the mechanism of brain plasticity in patients with GAD and evaluate the effectiveness and reliability of acupuncture treatment.

Methods: A total of 8 patients with PP aged between 18 and 60 years were recruited and treated with FA once a week, and the lesion area and severity index (PASI), visual analog scale and pruritus were measured before, 2, 4 and 8 weeks after treatment and at the follow-up period (week 12), respectively. Visual analog scale, and dermoscopy were used for assessment.
Background: Modulating loop-mediated isothermal amplification (mLAMP) by short-stranded DNA segment trigger (T) to generate byproducts H ions (mLAMP/H) as signal transducer is intriguing for developing catalytic hairpin assembly (CHA)-cooperated amplifiable electrochemical biosensors. This would be a big challenge for traditional LAMP that is basically suitable for amplifying long-stranded oligonucleotides up to 200-300 nt. To address this inherent limitation of traditional LAMP, many researchers have put in efforts to explore improvements in this that would allow LAMP to be used for a wider range of target species amplification.

They can be "parasitized" by intracellular bacteria, serving as "accomplices", protecting intracellular bacteria and even switching them to persisters. Here, using a freeze-thaw strategy-based microfluidic chip, a "Themis" nanocomplex (TNC) is created.

However, the multiplexing capability of TPEF microscopy is limited by the narrow spectral bandwidth of the light source. In this study, we apply a photonic crystal fiber in TPEF microscopy to broaden the excitation source bandwidth.

The therapeutic effect of acupuncture is well known in Traditional Chinese medicine (TCM) due to its unique non-pharmacological nature. Electroacupuncture (EA) for antidepressant therapy has been widely recognized and used in clinic.

Methods: Eight patients (5 females and 3 males; mean age, 34.2 years) with complex anterior cerebral artery aneurysms were treated with bypass.
Background: Annexin A1 might be neuroprotective and serum annexin A1 concentrations were markedly declined after severe traumatic brain injury. We determine dthe ability of serum annexin A1 to assess severity and predict prognosis after aneurysmal subarachnoid hemorrhage (aSAH).
Methods: We included 157 aSAH patients and 157 healthy subjects.
Background: Substance P (SP) is implicated in brain inflammation. We clarified relationship between serum SP concentrations and functional outcome of acute intracerebral hemorrhage (ICH).
Methods: We quantified admission serum SP concentrations in 106 ICH patients.
Objective: To investigate the effect of the interaction between methylenetetrahydrofolate reductase(MTHFR) genotype and allele and long-term exposure to organophosphorus pesticides on the development of type 2 diabetes mellitus(T2 DM).
Methods: A total of 209 cases of T2 DM(case group) and 216 cases without T2 DM(control group) were selected as subjects. The polymorphism of MTHFR(rs1801133) was detected by TaqMan probe technique.
Background: Bone marrow stromal or stem cells (BMSCs) remain a promising potential therapy for ischemic cardiomyopathy. The primary objective of this study was to evaluate the safety and feasibility of direct intramyocardial injection of autologous BMSCs in patients undergoing transmyocardial revascularization (TMR) or coronary artery bypass graft surgery (CABG).
Methods: A phase I trial was conducted on adult patients who had ischemic heart disease with depressed left ventricular ejection fraction and who were scheduled to undergo TMR or CABG.
The ability to fabricate perfusable, small-diameter vasculature is a foundational step toward generating human tissues/organs for clinical applications. Currently, it is highly challenging to generate vasculature integrated with smooth muscle and endothelium that replicates the complexity and functionality of natural vessels. Here, a novel method for directly printing self-standing, small-diameter vasculature with smooth muscle and endothelium is presented through combining tailored mussel-inspired bioink and unique 'fugitive-migration' tactics, and its effectiveness and advantages over other methods (i.

Methods: The reprogramming of passage 3 myocardial fibroblasts was performed by using the lentiviral vector containing 4 human factors: OCT4, SOX2, KLF4, and c-MYC. The iPSC colonies at P12-17 were allogeneically transplanted into ischemic myocardium of 10 swine by direct injection.
Objectives: We sought to investigate if autologous freshly isolated regulatory T cells (Tregs) provide a protective and supportive role when cotransplanted with mesenchymal stem cells (MSCs).
Methods: In a porcine model of chronic ischemia, autologous MSCs were isolated and expanded ex vivo for 4 weeks. Autologous Treg cells were freshly isolated from 100 mL peripheral blood and purified by fluorescence-activated cell sorting.
Studying the proliferative ability of human bone marrow derived mesenchymal stem cells in hypoxic conditions can help us achieve the effective regeneration of ischemic injured myocardium. Cardiac-type fatty acid binding protein (FABP3) is a specific biomarker of muscle and heart tissue injury. This protein is purported to be involved in early myocardial development, adult myocardial tissue repair and responsible for the modulation of cell growth and proliferation.

Methods: Sixteen healthy male SD rats aged 3, 6 and 12 weeks were equally randomized into an experimental group (testicular torsion/detorsion plus Shengmai injection) and a control group (testicular torsion/detorsion plus saline). The rat models of testicular torsion were killed 24 h after surgery for the measurement of total antioxidant capacity (T-AOC), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis.
Background: Marrow stromal cells (MSCs) are reportedly able to improve ventricular function after myocardial infarction through the paracrine effect or regenerating myocytes. However, the evidence to prove that is scant. In this animal study, we employed MSCs isolated from transgenic pigs designed to express enhanced green fluorescent proteins as the donor to study the fate of the cells after allogeneic transplantation.
