Article Synopsis
  • - Ageing is a major factor in developing osteoarthritis (OA), and this study examines how phosphoinositide-specific phospholipase Cγ (PLCγ1) influences age-related changes in cartilage and bone linked to OA.
  • - Researchers used d-galactose (d-Gal) to induce chondrocyte senescence in rat and mouse models, using various lab techniques to measure cell growth and gene expression, revealing that d-Gal promotes ageing in cartilage and causes abnormalities in subchondral bone.
  • - Findings indicate that decreased PLCγ1 expression in chondrocytes leads to greater senescence and accelerated ageing changes in cartilage and bone; thus, PLCγ1 could be a potential therapeutic target

A comparative study was performed to investigate the differences in plasma pharmacokinetics (PKs) and tissue residues of trimethoprim (TMP) between silky fowls and 817 broilers. The 2 breeds of chickens received compound sulfadiazine suspension by gavage at 20 mg/kg (measured as TMP). Blood and tissue samples were collected at predetermined time points.

Background: Due to disparities in medical resources in rural and urban areas as well as in different geographic regions in China, the effect of weekend versus weekday admission on the outcomes of acute ischemic stroke (AIS) patients is unknown. Our aim was to investigate whether the outcomes of AIS patients differ according to the day of admission in China.

Methods: The data were extracted from the Chinese Acute Ischemic Stroke Treatment Outcome Registry (CASTOR), a multicenter prospective study database of patients diagnosed with AIS.

Background & Aims: The matricellular protein periostin plays a critical role in liver inflammation, fibrosis, and even carcinoma. Here, the biological function of periostin in alcohol-related liver disease (ALD) was investigated.

Methods: We used wild-type (WT), Postn-null (Postn) mice and Postn mice with periostin recovery to investigate the biological function of periostin in ALD.

Objective: To analyze the clinical features and variants of ABCD1 gene in a Chinese pedigree affected with X-linked adrenoleukodystrophy.

Methods: Clinical data of the proband were collected and analyzed. Potential variant of the ABCD1 gene were analyzed by PCR and Sanger sequencing of the proband, his parents and 100 unrelated healthy individuals.

Studies on the regional differences in hospital costs of acute ischemic stroke (AIS) are scarce in China. We aimed to explore the regional differences in hospital costs and identify the determinants of hospital costs in each region. Data were collected from the Chinese Acute Ischemic Stroke Treatment Outcome Registry (CASTOR), a multicenter prospective study on patients diagnosed with AIS and hospitalized from 2015 to 2017.

( transcription factors, specific to plants, act as crucial regulators of plant organ growth and development. Here, we examined the (alfalfa) gene family (s) to analyze the structure and function of s using bioinformatics methods, and verify their abiotic stress responses through growth experiments. Twenty-seven genes were identified from the genome-wide data of nontransgenic alfalfa.

There is limited information on symptomatic intracranial hemorrhage (sICH) in stroke patients without thrombolysis. This study aimed to evaluate the risk factors of sICH and the association between sICH and the prognosis at 3 and 12 months in acute ischemic stroke patients without thrombolysis. Data originated from the Chinese Acute Ischemic Stroke Treatment Outcome Registry.

Peroxynitrite (ONOO) and high mobility group box 1 protein (HMGB1) are important cytotoxic factors contributing to cerebral ischemia-reperfusion injury. However, the roles of ONOO in mediating HMGB1 expression and its impacts on hemorrhagic transformation (HT) in ischemic brain injury with delayed t-PA treatment remain unclear. In the present study, we tested the hypothesis that ONOO could directly mediate the activation and release of HMGB1 in ischemic brains with delayed t-PA treatment.

There are numerous types of pathological changes in human immunodeficiency virus (HIV)-associated neurocognitive disorder (HAND), including apoptosis of neurons. HIV-1 transactivator of transcription (Tat) protein, which is encoded by HIV-1, may promote apoptosis in HAND. Forkhead box O3 (FOXO3) is a multispecific transcription factor that has roles in many biological processes, including cellular apoptosis.

Activated autophagy/mitophagy has been intensively observed in ischemic brain, but its roles remain controversial. Peroxynitrite (ONOO), as a representative of reactive nitrogen species, is considered as a critical neurotoxic factor in mediating cerebral ischemia-reperfusion (I/R) injury, but its roles in autophagy/mitophagy activation remain unclear. Herein, we hypothesized that ONOO could induce PINK1/Parkin-mediated mitophagy activation via triggering dynamin-related protein 1 (Drp1) recruitment to damaged mitochondria, contributing to cerebral I/R injury.

Tissue plasminogen activator (t-PA) has a restrictive therapeutic window within 4.5 h after ischemic stroke with the risk of hemorrhagic transformation (HT) and neurotoxicity when it is used beyond the time window. In the present study, we tested the hypothesis that baicalin, an active compound of medicinal plant, could attenuate HT in cerebral ischemia stroke with delayed t-PA treatment.

During HIV-associated neurocognitive disorder (HAND), decreasing in excitatory amino acid transporter 2 (EAAT-2) in astrocyte plasma membranes leads to elevated levels of extracellular glutamate and, in turn, neuronal apoptosis. We used immunohistochemistry, western blot, qRT-PCR, and RNA interference to elucidate the molecular mechanisms underlying the decreased EAAT-2 expression during HAND at the tissue and cellular levels. We used simian immunodeficiency virus-human immunodeficiency virus chimeric virus (SHIV)-infected macaques as an in vivo model of HAND.

The molecular mechanisms involved in human immunodeficiency virus (HIV)-associated neurocognitive disorder (HAND) remain poorly understood. It has been recently reported that HIV-1 Tat transactivation requires menin, suggesting that menin may be involved in HAND pathogenesis. But the role of menin is not clear.

Background: TNFAIP8, also known as TIPE, is a suppressor of apoptosis. High expression of both TIPE mRNA and protein has been detected in various cancer cell lines and clinical specimens compared to healthy tissues. Many reports have shown that there is a strong correlation between TIPE overexpression and cancer progression and poor prognosis in human solid cancers.

Article Synopsis
  • Alzheimer's disease (AD) is primarily characterized by the buildup of amyloid β (Aβ) in the brain, which is linked to dementia.
  • MicroRNAs (miRNAs) play a critical role in regulating genes that affect Aβ metabolism, and their expression levels change during AD progression, making them potential diagnostic markers.
  • The study used a mouse model to identify altered miRNA levels, discovering nine common miRNAs between sibling pairs, which appear to influence genes in the PI3K/Akt signaling pathway, shedding light on Aβ-induced neuronal dysfunction in AD.
