Single-Dose Physically Cross-Linked Hyaluronic Acid and Lipid Hybrid Nanoparticles Containing Cyclic Guanosine Monophosphate-Adenosine Monophosphate Eliminate Established Tumors.

Activating the STING pathway in the cytosol of tumor-infiltrating antigen-presenting cells (APCs) represents a promising strategy to elicit potent antitumor immune responses for cancer therapy. However, STING agonists are mostly small hydrophilic molecules that suffer from rapid clearance and poor cytosolic delivery following systemic administration. While various nanoparticles have been developed to promote cytosolic delivery, they often exhibit premature drug release during circulation.

A Virus-Inspired Inhalable Liponanogel Induces Potent Antitumor Immunity and Regression in Metastatic Lung Tumors.

Pulmonary delivery of immunostimulatory agents such as poly(I:C) to activate double-stranded RNA sensors MDA5 and RIG-I within lung-resident antigen-presenting cells is a potential strategy to enhance antitumor immunity by promoting type I interferon secretion. Nevertheless, following pulmonary delivery, poly(I:C) suffers from rapid degradation and poor endosomal escape, thus limiting its potency. Inspired by the structure of a virus that utilizes internal viral proteins to tune the loading and cytosolic delivery of viral nucleic acids, we developed a liponanogel (LNG)-based platform to overcome the delivery challenges of poly(I:C).

Predicting lung cancer survival prognosis based on the conditional survival bayesian network.

Lung cancer is a leading cause of cancer deaths and imposes an enormous economic burden on patients. It is important to develop an accurate risk assessment model to determine the appropriate treatment for patients after an initial lung cancer diagnosis. The Cox proportional hazards model is mainly employed in survival analysis.

Design and fabrication of r-hirudin loaded dissolving microneedle patch for minimally invasive and long-term treatment of thromboembolic disease.

Cardiovascular disease is the leading cause of global mortality, with anticoagulant therapy being the main prevention and treatment strategy. Recombinant hirudin (r-hirudin) is a direct thrombin inhibitor that can potentially prevent thrombosis via subcutaneous (SC) and intravenous (IV) administration, but there is a risk of haemorrhage via SC and IV. Thus, microneedle (MN) provides painless and sanitary alternatives to syringes and oral administration.

LTM-TCM: A comprehensive database for the linking of Traditional Chinese Medicine with modern medicine at molecular and phenotypic levels.

Benefiting from the development of network pharmacology, Traditional Chinese Medicine (TCM) shows great potential in modern drug discovery. Recently, more and more TCM-related databases have been established for both academic and industry research, but they are still insufficient in data standardization, integrity, and precision. To better accelerate the TCM research and overcome these shortcomings, we construct a web-based TCM platform, LTM-TCM, which is currently the most comprehensive TCM database that includes the following advantages: (1) High-quality data integration from fourteen TCM authoritative databases, especially with additional manual collected 41,025 clinical treatment records and 213 ancient Chinese medical books.

Early argatroban and antiplatelet combination therapy in acute non-lacunar single subcortical infarct associated with mild intracranial atherosclerosis.

Background: Patients with acute non-lacunar single subcortical infarct (SSI) associated with mild intracranial atherosclerosis (ICAS) have a relatively high incidence of early neurological deterioration (END), resulting in unfavorable functional outcomes. Whether the early administration of argatroban and aspirin or clopidogrel within 6-12 h after symptom onset is effective and safe in these patients is unknown.

Methods: A review of the stroke database of Weihai Municipal Hospital, Cheeloo College of Medicine, Shandong University and Qingdao Center Hospital, Qingdao University Medical College in China was undertaken from May 2017 to January 2020 to identify all patients with non-lacunar SSI caused by ICAS within 6-12 h of symptom onset based on MRI screening.

Enhanced Efficiency of flySAM by Optimization of sgRNA Parameters in .

The flySAM/CRISPRa system has recently emerged as a powerful tool for gain-of-function studies in This system includes Gal4/UAS-driven dCas9 activators and U6 promoter-controlled sgRNA. Having established dCas9 activators superior to other combinations, to further enhance the efficiency of the targeting activators we systematically optimized the parameters of the sgRNA. Interestingly, the most efficient sgRNAs were found to accumulate in the region from -150bp to -450bp upstream of the transcription start site (TSS), and the activation efficiency showed a strong positive correlation with the GC content of the sgRNA targeting sequence.

Detection and Treatment of Persistent Mullerian Duct Syndrome With Transverse Testicular Ectopia.

The coexistence of persistent Mullerian duct syndrome (PMDS) with transverse testicular ectopia (TTE) is extremely rare. Due to a lack of distinctive clinical features in the early stages, PMDS coexists with TTE is usuallydiagnosed when patients are examined for other diseases,including cryptorchidism and inguinal hernia. We present a case of a 51-year-old man who presented with a recurrent left indirect inguinal hernia for 2 years and right congenital cryptorchidism.

Large-Scale Transgenic Resource Collections for Loss- and Gain-of-Function Studies.

The Transgenic RNAi Project (TRiP), a functional genomics platform at Harvard Medical School, was initiated in 2008 to generate and distribute a genome-scale collection of RNA interference (RNAi) fly stocks. To date, it has generated >15,000 RNAi fly stocks. As this covers most genes, we have largely transitioned to development of new resources based on CRISPR technology.
