Amplification-free smartphone-based attomolar HBV detection.

Biosens Bioelectron 2021 Sep 11;194:113622. Epub 2021 Sep 11.

Joint International Research Laboratory of Animal Health and Food Safety of Ministry of Education & Single Molecule Nanometry Laboratory (Sinmolab), Nanjing Agricultural University, Nanjing, Jiangsu, 210095, China. Electronic address:

Classical gold standard HBV detection relies on expensive devices and complicated procedures, thus is always restricted in large-scale hospitals and centers for disease control and prevention. To extend HBV detection to primary clinics especially in underdeveloped areas, we design amplification-free smartphone-based attomolar HBV detecting technique based on single molecule sensing. Verified by synthesized HBV target DNA, this technique reaches a detection limit at attomolar concentration (100 aM); and verified by 110 clinical samples, it also reaches a rather high sensitivity of 10 copy/mL (≈2000 IU/mL) with a high accuracy of 93.

An improved sample extraction method reveals that plasma receptor for advanced glycation end-products (RAGE) modulates circulating free oxytocin in mice.

Peptides 2021 Sep 17:170649. Epub 2021 Sep 17.

Department of Basic Research on Social Recognition and Memory, Research Center for Child Mental Development, Kanazawa University, Kanazawa, 920-8640, Japan. Electronic address:

The receptor for advanced glycation end-products (RAGE) binds oxytocin (OT) and transports it from the blood to the brain. As RAGE's OT-binding capacity was lost in RAGE knockout (KO) mice, we predicted that circulating concentrations of unbound (free) OT should be elevated compared to wild-type (WT) mice. However, this hypothesis has not yet been investigated. Read More

DHNLDA: A novel deep hierarchical network based method for predicting lncRNA-disease associations.

IEEE/ACM Trans Comput Biol Bioinform 2021 Sep 20;PP. Epub 2021 Sep 20.

Recent studies have found that lncRNA (long non-coding RNA) in ncRNA (non-coding RNA) is not only involved in many biological processes, but also abnormally expressed in many complex diseases. Identification of lncRNA-disease associations accurately is of great significance for understanding the function of lncRNA and disease mechanism. In this paper, a deep learning framework consisting of stacked autoencoder(SAE), multi-scale ResNet and stacked ensemble module, named DHNLDA, was constructed to predict lncRNA-disease associations, which integrates multiple biological data sources and constructing feature matrices.

Methods Mol Biol 2022 ;2364:237-249

Protein Purification, Kemp Proteins, Frederick, MD, USA.

Actin, myosin, and tubulin are ubiquitous components of the fibrous network known as the cytoskeleton. Cytoskeletal proteins are involved in a plethora of intracellular processes such as maintenance of cellular organization, organelle translocation, and various nuclear roles including chromosome separation during mitosis. Early methods for protein extraction primarily relied on the salting-out method which was performed in conjunction with biochemical assays. Read More

Imaging Cytoskeleton Components by Electron Microscopy.

Tatyana Svitkina

Methods Mol Biol 2022 ;2364:25-52

Department of Biology, University of Pennsylvania, Philadelphia, PA, USA.

The cytoskeleton is a complex of detergent-insoluble components of the cytoplasm playing critical roles in cell motility, shape generation, and mechanical properties of a cell. Fibrillar polymers-actin filaments, microtubules, and intermediate filaments-are major constituents of the cytoskeleton, which constantly change their organization during cellular activities. The actin cytoskeleton is especially polymorphic, as actin filaments can form multiple higher-order assemblies performing different functions. Read More

Computational elucidation of the aging time effect on zeolite synthesis selectivity in the presence of water and diquaternary ammonium iodide.

Phys Chem Chem Phys 2021 Sep 20. Epub 2021 Sep 20.

Research Institute of Petroleum Industry, West Blvd. of Azadi Complex, Tehran 1485733111, Iran.

An example of zeolite selectivity (MFI → MOR) driven by synthesis aging time has been studied. Using ,,','-tetramethyl-,'-dipropyl-ethylenediammonium diiodide (TMDP) as an organic structure-directing agent (OSDA), the zeolite phases obtained at 2 h (MFI 97%), 8 h (MFI 84%, MOR 16%) and 24 h (MFI 43%, MOR 57%) have been characterized by powder X-ray diffraction. The results suggest that at intermediate aging time, namely 8 h and 24 h, the dominant phase (MFI) is displaced by MOR. Read More

Three-Port with Natural Orifice Specimen Extraction versus Conventional Laparoscopic Anterior Resection for Rectal-Sigmoid Cancer: A Matched Pair Analysis.

J Invest Surg 2021 Sep 20:1-5. Epub 2021 Sep 20.

Division of Colorectal Surgery, Changzheng Hospital, Shanghai, P.R. China.

Background: The conventional laparoscopic colorectal surgery requires four or more ports to accomplish the laparoscopic dissection, and a mini-laparotomy to remove the specimen, which is a main cause of postoperative pain and incision complications, and compromise the cosmetic results. Reduced port surgery and natural orifice specimen extraction (NOSE) surgery hold the promise to overcome these drawbacks. This study planned to compare peri-operative outcomes of patients with rectal-sigmoid cancer undergoing three-port laparoscopic anterior resection with NOSE (three-port NOSE LAR) to those of patients receiving conventional LAR.

Guangdong-Hong Kong-Macao Joint Laboratory for Contaminants Exposure and Health, Guangdong Key Laboratory of Environmental Catalysis and Health Risk Control, Institute of Environmental Health and Pollution Control, Guangdong University of Technology, Guangzhou 510006, P. R. China.

Household dust is a sink for multiple toxic chemicals with known or suspected potential health effects. However, most dust exposure studies focus on a few chemicals, which may limit overall understanding of human exposure characteristics because people spend most of their time indoors. This paper describes the development and evaluation of a multi-residue analysis of 20 organochlorine pesticides (OCPs), 15 polycyclic aromatic hydrocarbons (PAHs), 8 polybrominated diphenyl ether congeners (PBDEs), 3 hexabromocyclododecane (HBCDs), 8 synthetic musks (Musks), and 7 organophosphate esters (OPEs) in indoor dusts.
