Peroxide test strip (PTS) has been widely used for the point-of-care testing (POCT), but its poor sensitivity is a big obstacle for analyzing trace target. Herein, a triple signal amplifying platform integrating the liposome enrichment, the hybridization chain reaction (HCR) circuit, and the image analysis method was constructed to enhance the visual readout of PTS for the sensitive detection of adenosine triphosphate (ATP), an important biomarker of food spoilage. In the presence of ATP, the HCR amplifier was firstly initiated on the surface of magnetic beads (MBs), inducing a large number of glucose oxidase (GOD) imbedded liposomes to be attached.

Article Synopsis
  • - The study investigates the link between indoor air pollution from cooking with solid fuels and the risk of "possible sarcopenia" in middle-aged and older Chinese individuals, using data from the China Health and Retirement Longitudinal Study.
  • - Out of 17,708 participants tracked over 4 years, 1,532 developed possible sarcopenia, with those using solid fuels at a significantly higher risk compared to those using clean fuels.
  • - The results highlight that solid fuel use is a modifiable risk factor for sarcopenia, particularly impacting middle-aged women, suggesting that improving cooking fuel types could serve as a prevention strategy.

-Alkyl-2'-deoxyguanosine (-alkyl-dG) is a major type of minor-groove DNA lesions arising from endogenous metabolic processes and exogenous exposure to environmental contaminants. The -alkyl-dG lesions, if left unrepaired, can block DNA replication and transcription and induce mutations in these processes. Nevertheless, the repair pathways for -alkyl-dG lesions remain incompletely elucidated.

Background: Diabetes mellitus is generally accompanied by dyslipidaemia, but inconsistent relationships between lipid profiles and diabetes are noted. Moreover, genetic variations in insertion/deletion (I/D) polymorphisms at angiotensin-converting enzyme gene (ACE) and T/C polymorphisms in the angiotensin type 1 receptor gene (AGTR1) are related to diabetes and lipid levels, but the associations are controversial. Thus, the current research aimed to explore the effects of ACE I/D, AGTR1 rs5182 and diabetes mellitus on serum lipid profiles in 385 Chinese participants with an average age of 75.

Article Synopsis
  • Vertebrate radial glia progenitors (RGPs) are key neural stem cells that use asymmetric cell division to balance self-renewal and differentiation, with centrosome inheritance influencing offspring fate.
  • Researchers discovered that the centrosome protein Pcm1, which is unevenly distributed in RGPs, plays a crucial role in controlling endosome dynamics and affecting cell fate by impacting Notch signaling during ACD.
  • Their findings indicate that Pcm1 facilitates the transition of endosome markers and establishes molecular complexes that influence progenitor production, and they observed similar patterns in human brain organoids, revealing insights into how centrosome asymmetry relates to RGP function.

Article Synopsis
  • The study investigates how psychosocial stress impacts serum cholesterol levels and its connection to psychological and endocrine disorders, highlighting that this relationship has not been fully explored yet.
  • Findings indicate that stress leads to increased serum corticosterone, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) in a mouse model, suggesting physiological changes triggered by stress.
  • The research reveals that elevated glucocorticoids from stress inhibit specific signaling pathways in the liver, resulting in reduced LDL-C clearance and increased cholesterol production.

The protocol presented here demonstrates the operation method of ultrasound-guided acupotomy for knee osteoarthritis (KOA), including patient recruitment, preoperative preparation, manual operation, and postoperative care. The purpose of this protocol is to relieve pain and improve knee function in patients with KOA. A total of 60 patients with KOA admitted between June 2022 and June 2023 were treated with ultrasound-guided acupotomy.

The coordination between actin and microtubule network is crucial, yet this remains a challenging problem to dissect and our understanding of the underlying mechanisms remains limited. In this study, we used travelling waves in the cell cortex to characterize the collective dynamics of cytoskeletal networks. Our findings show that Cdc42 and F-BAR-dependent actin waves in mast cells are mainly driven by formin-mediated actin polymerization, with the microtubule-binding formin FH2 domain-containing protein 1 (FHDC1) as an early regulator.

Objectives: This study was to explore blood pressure levels in Chinese adolescents with different genotypes of phosphatidylethanolamine N-methyltransferase (PEMT) gene ( PEMT ) rs7946, as well as effects of dietary intake on blood pressure levels with different genders and different genotypes of PEMT rs7946.

Methods: PEMT rs7946 genotypes were identified by PCR-restriction fragment length polymorphism and verified by DNA sequencing. Blood pressure was measured using a standard mercury sphygmomanometer.

Objective: To verify effects of rs1061622 at tumor necrosis factor-α receptor II (TNF-RII) gene (TNF-RII) on post-traumatic stress disorder (PTSD) and its interactive effects with PTSD on serum lipids levels in adolescents.

Methods: PTSD was measured by PTSD Checklist-Civilian Version (PCL-C) in 699 adolescent survivors at 6 months after Wenchuan earthquake in China. A polymerase chain reaction and restriction fragment length polymorphism assay were utilized for TNF-RII rs1061622 genotyping followed by verification using DNA sequencing.

Behavioral diversity is critical for population fitness. Individual differences in risk-taking are observed across species, but underlying genetic mechanisms and conservation are largely unknown. We examined dark avoidance in larval zebrafish, a motivated behavior reflecting an approach-avoidance conflict.

Melatonin (MT) is a crucial neuroendocrine regulator of various physiological activities in vertebrates, especially in circadian or seasonal rhythm control. In the present study, the large yellow croaker (), a marine bony fish with circadian body color change behavior, is chosen for functional investigation on teleost MT signaling systems that remain uncharacterized. All five melatonin receptors (Mtnr1a1, Mtnr1a2, Mtnr1b1, Mtnr1b2, and Mtnr1c) were significantly activated by MT, triggering extracellular signal-regulated kinase 1/2 (ERK1/2) phosphorylation through different G protein coupling signaling pathways, with exclusive G-dependency for Mtnr1a2 and Mtnr1c, and G-dependency for two Mtnr1b paralogs, whereas Mtnr1a1 activated G and G dual-dependent signaling pathways.

Asymmetric cell division (ACD), which produces two daughter cells of different fates, is fundamental for generating cellular diversity. In the developing organs of both invertebrates and vertebrates, asymmetrically dividing progenitors generates a Notch self-renewing and a Notch differentiating daughter. In the embryonic zebrafish brain, radial glia progenitors (RGPs)-the principal vertebrate neural stem cells-mostly undergo ACD to give birth to one RGP and one differentiating neuron.
