As a major environmental heavy metal pollutant, hexavalent chromium (Cr(VI)) causes irreversible damage to animals and humans. Nevertheless, how Cr(VI) exposure causes intestinal damage in broilers remains inadequately explored. This study explores Cr(VI)-induced poisoning using potassium dichromate to build a Cr(VI) poisoning model.

In the Chinese cultural context, the collaborative interaction characteristics among three key entities - families, kindergartens, and communities - and the mechanisms of their correlation with preschool children's social behavior problems have not been fully understood yet. Based on ecological systems Theory and social support theory, this study aimed to examine the correlation between parent-teacher relationships and preschool children's social behavior problems in Chinese kindergartens, as well as the mediating role of parents' work-family conflict and parenting self-efficacy. Structural equation modeling was used to test the research hypotheses based on a questionnaire survey of 1,784 parents of preschool children.

Article Synopsis
  • Peach brown rot, caused by Monilinia fructicola, threatens postharvest peach production with losses up to 80%, leading to interest in biological control methods due to chemical bans in many countries.* -
  • The study highlights Streptomyces lincolnensis strain JCP1-7, which, through eucalyptol, effectively inhibits M. fructicola sporulation with a 93.13% success rate.* -
  • Eucalyptol was found to impact key pathogenic pathways, particularly inhibiting the catalase 2 (Cat2) gene, suggesting it as a target for reducing peach brown rot in agricultural practices.*

Background: Peach brown rot, caused by the pathogen Monilinia fructicola, represents a significant postharvest infectious disease affecting peach fruit. This disease is responsible for a substantial increase in fruit decay rates, leading to significant economic losses, often exceeding 50%. Currently, there is a growing interest in identifying biocontrol agents to mitigate peach brown rot, with a predominant interest in Bacillus species.

Neuropsychiatric disorders shorten human life spans through multiple ways and become major threats to human health. Exercise can regulate the estrogen signaling, which may be involved in depression, Alzheimer's disease (AD) and Parkinson's disease (PD), and other neuropsychiatric disorders as well in their sex differences. In nervous system, estrogen is an important regulator of cell development, synaptic development, and brain connectivity.

Metabolic diseases such as obesity and diabetes are often thought to be caused by reduced energy expenditure, which poses a serious threat to human health. Cold exposure, exercise and caloric restriction have been shown to promote adipose tissue browning and thermogenesis. These physiological interventions increase energy expenditure and thus have emerged as promising strategies for mitigating metabolic disorders.

AMP-activated protein kinase (AMPK) is a sensor of energy status that maintains cellular energy homeostasis. Activation of AMPK enhances the expression of proliferator-activated receptor γ coactivator 1α (PGC1-α) and subsequently activates mitochondrial transcription factor A (TFAM) to regulate mitochondrial oxidative respiratory function. The possible functions of AMPK, p-AMPK, PGC-1α, and TFAM and their interactions in astrocytomas are not known.

Background: At present, the clinical efficacy of measured resection (MR) and gap balancing (GB) techniques in total knee arthroplasty (TKA) is still controversial. The objective of this study was to evaluate the clinical outcome indexes of the two surgical methods through a meta-analysis.

Methods: The literature was systematically searched on PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG, Weipu (VIP), and China Biomedical Literature (CBM) electronic databases inception until June 12, 2022.

Polymerase chain reaction (PCR) kits have been used as common diagnosing tools during the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, with daily worldwide usage in the millions. It is well known that at the beginning of the pandemic, there was a shortage of PCR kits. So far, the ecosystem of a PCR kit is linear use; that is, kits are produced, used once, and disposed of as biolab waste.

  • Tobacco mosaic disease is a viral issue that affects plants and can cause big money losses for farmers.
  • Researchers found a plant extract called ZhiNengCong (ZNC) that battles this disease and helps tobacco plants grow bigger.
  • They created a new form of ZNC mixed with a gel called sodium alginate (ZNC@Alg) that releases the medicine for 7 days and works really well, improving disease control from 65% to 88% in real-life tests.

Ribosome-inactivating proteins (RIPs) are toxic N-glycosylase that act on eukaryotic and prokaryotic rRNAs, resulting in arrest protein synthesis. RIPs are widely found in higher plant species and display strong antiviral activity. Previous studies have shown that PAP and α-MMC have antiviral activity against TMV.

hypoxia inducible factor-1α (HIF-1α) and pyruvate kinase M2 (PKM2) are 2 key metabolic regulatory proteins, they could engage in a positive feedback loop and drive cancer growth by enhancing glycolysis. This study aimed to investigate the expression of HIF-1α and PKM2 in papillary thyroid carcinoma (PTC) and its correlation with the patients clinicopathological features and with tumor invasion and metastasis. Surgically resected PTC specimens from 60 patients were collected.

Aims: To assess the effects of sugar-sweetened beverage (SSB) consumption and exercise on behaviors.

Methods: Twenty-four male mice were divided into four groups: the water + sedentary (WS), the SSB + sedentary (CS), the water + exercise (WE), and the SSB + exercise (CE). After three-month of interventions, forced swim test (FST), open field test (OFT), and morris water maze (MWM) were conducted.

A double-layer metal superlens was rigorously analyzed and systematically designed to improve subwavelength imaging ability. It was revealed that transmission properties of the imaging system could be accurately interpreted by the five-layer waveguide mode theory-each amplification peak among the spatial frequency range of evanescent waves was associated with a corresponding surface plasmon polariton (SPP) mode of an insulator-metal-insulator-metal-insulator (IMIMI) structure. On the basis of such physical insight, evanescent waves of higher spatial frequency were effectively amplified via increasing propagation constants of symmetrically coupled short-range SPP (s-SRSPP) and antisymmetrically coupled short-range SPP (a-SRSPP), and evanescent waves of lower spatial frequency were appropriately diminished by approaching to cut off symmetrically coupled long-range SPP (s-LRSPP).

Background: Prolonged periods of sedentary behaviour, for instance, engendered by home confinement in Shenzhen city, has led to negative mental health consequences, especially in adolescents. Previous research suggests, in general, that sedentary behavior can increase negative emotions. However, the specific mechanism driving the relationship between sedentary behavior and negative emotions is still relatively unclear.

Calcium is an important plant immune signal that is essential for activating host resistance, but how RNA viruses manipulate calcium signals to promote their infections remains largely unknown. Here, we demonstrated that tobacco mosaic virus (TMV) coat protein (CP)-interacting protein L (IP-L) associates with calmodulin-like protein 30 (NbCML30) in the cytoplasm and nucleus, and can suppress its expression at the nucleic acid and protein levels. NbCML30, which lacks the EF-hand conserved domain and cannot bind to Ca , was located in the cytoplasm and nucleus and was downregulated by TMV infection.

Sleep disorder caused by abnormal circadian rhythm is one of the main symptoms and risk factors of depression. As a known hormone regulating circadian rhythms, melatonin (MT) is also namely N-acetyl-5-methoxytryptamine. N-acetylserotonin methyltransferase (Asmt) is the key rate-limiting enzyme of MT synthesis and has been reportedly associated with depression.

Hexavalent chromium [Cr (VI)] is a common environmental pollutant. Although selenium (Se) can antagonize the toxicity of Cr (VI), the specific underlying mechanism has not been identified. To investigate this mechanism, we used potassium dichromate (KCrO) and selenium-rich yeast (SeY) to construct single Cr (VI)- and combined Se/Cr (VI)-exposed broiler models during a 42-day period.
