Article Synopsis
  • * In a study, chickens were divided into three groups (control, vaccine + adjuvant, and vaccine-only) to assess immune responses and the results showed significant increases in immune markers and lymphocyte populations in the group receiving the adjuvant.
  • * Overall, the adjuvant enhanced the immune response by upregulating key cytokines (IL-2, IL-4, TNF-α, IFN-γ) and promoting cell

Intestinal mucosa injury and loss of weight gain are unavoidable while using live vaccine strain to prevent chicken coccidiosis. In this study, recombinant Lactococcus lactis NZ3900/pNZ8149-IL-4-IL-2, expressing the fusion protein of chicken IL-4 and IL-2, was constructed using food-grade NICE expression system, trying to develop a possible oral immune adjuvant to enhance the immune effect of the live vaccine against chicken coccidiosis and minimize its adverse effects. Chickens were given different doses of recombinant L.

Background: To compare the long-term therapeutic effects of stereotactic aspiration (SA), endoscopic evacuation (EE), and open craniotomy (OC) in the surgical treatment of spontaneous basal ganglia hemorrhage and explore the appropriate clinical indications for each technique.

Methods: Multiple-treatment inverse probability of treatment weighting (IPTW)-adjusted logistic regression analysis was performed to evaluate the therapeutic effects of these techniques. The primary and secondary outcomes were 6-month modified Rankin Scale (mRS) and mortality rates, respectively.

Objectives: 20-hydroxyeicosatetraenoic acid (20-HETE) is a metabolite of arachidonic acid catalysed by cytochrome P450 enzymes and plays an important role in cell death and proliferation. We hypothesized that 20-HETE synthesis inhibition may have protective effects in traumatic brain injury (TBI) and investigated possible underlying molecular mechanisms.

Materials And Methods: Neurologic deficits, and lesion volume, reactive oxygen species (ROS) levels and cell death as assessed using immunofluorescence staining, transmission electron microscopy and Western blotting were used to determine post-TBI effects of HET0016, an inhibitor of 20-HETE synthesis, and their underlying mechanisms.

Carotid angioplasty stenting (CAS) is a currently widely used surgical treatment of carotid artery stenosis. However, the influences of the perioperative blood pressure (BP) on patients' prognosis remain unclear. The present study was designed to explore the effects of different perioperative BP control strategies on CAS patients' prognosis.

The surgical evacuation, including stereotactic aspiration, endoscopic evacuation, and craniotomy, is the most effective way to reduce the volume of intracerebral hemorrhage. However, credible evidence for the effects of these techniques is still insufficient. The present study explored the long-term outcomes of these techniques in the treatment of basal ganglia hematoma with low Glasgow Coma Scale (GCS) scores (≤8) and large-volume (≥40 ml), which were predictors of high mortality.

Clinical advances in the treatment of intracranial hemorrhage (ICH) are restricted by the incomplete understanding of the molecular mechanisms contributing to secondary brain injury. Acrolein is a highly active unsaturated aldehyde which has been implicated in many nervous system diseases. Our results indicated a significant increase in the level of acrolein after ICH in mouse brain.

The present study aims to investigate the similarities and differences between the host cells apoptosis induced by virulent line of Eimeria tenella (Tsx) and precocious line (PTsx), which can provide a theoretical basis for the study of drugs and vaccines against coccidiosis. HE staining, Hoechst 33342/AnnexinV-FITC/PI composite staining, and ELISA were used to detect the infection rate, apoptosis rate, and Caspase-3 enzyme activity of host cells infected by PTsx or Tsx, respectively. The apoptotic rates and Caspase-3 absorbance of the inoculation groups were lower (P < 0.

Long noncoding RNAs (lncRNAs) have been reported to participate in tumorigenesis and diverse cellular processes in osteosarcoma (OS). However, the role of lncRNA LINC00152 in OS remains elusive. In this study, LINC00152 was highly expressed in osteosarcoma tissues and cell lines.

Ischemic stroke is a severe cerebrovascular disease. Although great progress has been made, the consequent ischemia-reperfusion (I/R) injury is inevitable and affects the therapeutic effect. Adiponectin (APN) is a fat-derived plasma protein that has beneficial actions on cardiovascular disorders.

The effects of long non-coding RNAs (lncRNAs) on cellular biological processes and even the tumorigenesis have been widely reported. Small nucleolar RNA host gene 6 (SNHG6) has been reported to participate in regulating biological behaviors of multiple types of cancers. Nevertheless, the functions of SNHG6 in osteosarcoma still remain to be uncovered.

Article Synopsis
  • PRRSV is a virus causing significant issues in pigs, and researchers previously found a DNA-based antisense oligonucleotide (AS-ON) that effectively reduces its replication.
  • The study modified this AS-ON using locked nucleic acids (LNAs) to enhance its effectiveness, testing them in cell cultures infected with PRRSV.
  • Results showed that LNA-modified AS-ONs improved cell viability and significantly reduced viral replication compared to the original DNA-based AS-ON, indicating better potential for controlling PRRS.

Hepatoma-derived growth factor (HDGF) regulates various cellular processes involved in the onset and development of tumors. To evaluate the role of HDGF in human gliomas, western blotting analysis, immunohistochemistry staining and reverse transcription-quantitative polymerase chain reaction were performed to detect HDGF protein and mRNA expression levels in glioma and intractable epileptic brain tissue. Various clinicopathological characteristics, including age, gender, World health Organization grade, HDGF expression level, Karnofsky performance Status (KPS) and Ki-67 index were obtained from medical records.

Spontaneous intracerebral hemorrhage (ICH) is a devastating form of stroke, which leads to a high rate of mortality and poor neurological outcomes worldwide. Thrombolytic evacuation with urokinase-type plasminogen activator (uPA) or tissue-type plasminogen activator (tPA) has been showed to be a hopeful treatment for ICH. However, to the best of our knowledge, no clinical trials were reported to compare the efficacy and safety of these two fibrinolytics administrated following minimally invasive stereotactic puncture (MISP) in patients with spontaneous basal ganglia ICH.

Article Synopsis
  • The study investigated how TRPC7, a type of ion channel, is expressed in normal vs. hypertrophic heart cells.
  • Using a model of renovascular hypertension in rats, researchers found that TRPC7 expression decreased significantly in hypertrophied cardiac tissue while another protein, PKC, increased.
  • Treatment with losartan, an Ang II receptor blocker, not only reduced hypertension and heart enlargement but also helped restore TRPC7 levels, suggesting TRPC7's important role in heart function.

Background: Porcine reproductive and respiratory syndrome (PRRS) is caused by porcine reproductive and respiratory syndrome virus (PRRSV) and is an economically important disease in swine-producing areas. The objective of this study was to screen for effective antisense oligonucleotides (AS-ONs) which could inhibit PRRSV replication in MARC-145 cells and in pulmonary alveolar macrophages (PAM).

Results: Nine short AS-ON sequences against the well-conserved regions of PRRSV (5'-UTR, NSP9, ORF5 and ORF7) were selected.

Microglia activation plays an important role in neuroinflammation. Sirtuin1 (SIRT1) has been shown to play a role in regulation of inflammation. Resveratrol, a potent SIRT1 activator, has anti-inflammation property.

Inflammatory markers have been associated with functional outcome and mortality of stroke. We investigated the changes in procalcitonin (PCT) and high-sensitivity C-reactive protein (Hs-CRP) levels during the acute period of ischemic stroke and evaluated the relationship between these levels and the long-term functional outcome and mortality. We prospectively studied 376 patients with acute ischemic stroke (AIS) who were admitted within 24 h after the onset of symptoms.
