In this study, we aim to investigate the role of tanshinone IIA in myocardial infarction (MI), especially in left ventricular remodelling (VR) and the underlying mechanism involving the TLR4/MyD88/NF-κB signalling pathway. Sprague-Dawley (SD) rats (n = 96) were selected, and 12 of them underwent sham surgery. The remaining 84 rats were subjected to MI modelling. HE and MT staining were carried out to estimate infract size, histopathological changes and fibrosis degree. Macrophage infiltration and cardiomyocyte apoptosis were evaluated by immunohistochemistry and TUNEL staining...

The aim of this study was to evaluate the neuroendocrine and inflammation response to laparoscopic total ovariohysterectomy (TOH) in rabbits, by comparing surgical stress markers of laparoscopic group with those of conventional open ovariohysterectomy and open ovariohysterectomy with pre-incisional local anaesthesia groups. Blood was sampled from 18 rabbits, of which six underwent laparoscopic TOH, six conventional open TOH and six conventional open TOH with pre-incisional local anaesthesia, 30 min before induction of anaesthesia (T0), immediately after skin incision (T1), 90 min postoperatively (T2), and 24 h postoperatively (T3)...

PURPOSE: Irregular blood flow and endothelial cell anergy, which characterize many solid tumors, hinder tumor infiltration by cytotoxic T lymphocytes (CTLs). This confers resistance to cancer immunotherapy with monoclonal antibodies directed against regulatory pathways in T lymphocytes (i.e., immune checkpoint blockade, ICB). We investigated whether NGR-TNF, a TNF derivative capable of targeting the tumor vasculature, and improving intra-tumor infiltration by activated CTLs, could sensitize tumors to ICB with antibodies specific for the PD-1 and CTLA-4 receptors...

OBJECTIVE: We conducted the research in order to explore the impact of hydrosalpinx fluid (HSF) on endometrium. METHOD: HSF group: 261 patients with HSF scheduled to undergo laparoscopic surgery 3 to 7 days after menstruation in our center. Hysteroscopy would also be performed in order to observe the endometrial morphology during the surgery. Sixty (60) patients would be randomly selected for endometrial biopsy in order to detect the inflammatory cytokines TNF-a and IL-2 mRNA...

Portulaca oleracea L. is a traditional Chinese medicine, which has been used as adjuvant therapy for inflammatory bowel disease (IBD). However, the mechanism of its activity in IBD still remains unclear. Since previous studies have documented the anti-inflammatory effect of peroxisome proliferator activated receptors- γ (PPAR- γ ), Portulaca regulation of PPAR- γ in inflammation was examined in current study. Ulcerative colitis (UC) was generated by 5% dextran sulfate sodium (DSS) in mice and four groups were established as normal control, DSS alone, DSS plus mesalamine, and DSS plus Portulaca ...

BACKGROUND: Previous studies have suggested that tumor necrosis factor a (TNF-a), encoded by TNF gene, can increase osteoclast formation, and that specific alleles of the TNF gene are associated with postmenopausal osteoporosis susceptibility in some populations; however, the exact molecular mechanism remains unknown. AIMS: To investigate the potential association of nineteen polymorphisms of the TNF gene with postmenopausal osteoporosis and bone mineral density (BMD) traits in a sample of 1288 postmenopausal women from the Han Chinese population...

Hepatoma-derived growth factor (HDGF) is a potent mitogen for vascular smooth muscle cells (SMCs) during embryogenesis and injury repair of vessel walls. Whether mechanical stimuli modulate HDGF expression remains unknown. This study aimed at investigating whether cyclic mechanical stretch plays a regulatory role in HDGF expression and regenerative cytokine production in aortic SMCs. A SMC cell line was grown on a silicone-based elastomer chamber with extracellular matrix coatings (either type I collagen or fibronectin) and received cyclic and uni-axial mechanical stretches with 10% deformation at frequency 1 Hz...

INTRODUCTION: Patients diagnosed with schizophrenia display deficits in Theory of Mind (ToM) and Emotion Perception (EP) even before the appearance of full-blown symptomatology. METHODS: We evaluated ToM and EP in a male cohort consisting of 25 First Episode Psychosis (FEP) and 16 relapsed schizophrenic patients (CHRON) compared to 12 subjects in Ultra-high Risk (UHR) and 23 healthy controls (CTR). Furthermore, we measured the levels of Cortisol, Insulin like Growth Factor (IGF-1), TNF-a, TNF-b and several interleukins as potential biomarkers...

PURPOSE: T cell dysfunction is a hallmark of GBM. While anergy and tolerance have been well characterized, T cell exhaustion remains relatively unexplored. Exhaustion, characterized in part by the upregulation of multiple immune checkpoints, is a known contributor to failures amidst immune checkpoint blockade, a strategy that has lacked success thus far in GBM. This study is among the first to examine, and credential as bona fide, exhaustion among T cells infiltrating human and murine GBM...

INTRODUCTION: Both periodontitis and type II diabetes mellitus (T2DM) are common diseases with a multifactorial etiology and have influence of cytokines in their pathogenesis and thus may also influence each other. In recent times, more attention has been given to understanding the influences of these inflammatory cytokines which are a main part of oral chronic inflammation on systemic health of the individuals. Therefore, the aim of this study was to evaluate the plasma cytokine levels, specifically tumor necrosis factor-a (TNF-a), interleukin (IL)-6, and IL-4, in chronic periodontitis patients and T2DM patients, so as to investigate the influence of chronic periodontitis in systemic inflammation associated with diabetes mellitus...

BACKGROUND: The present study was conducted to investigate the effects of oridonin (ORI) on growth performance, relative organ weight, lymphocyte proliferation, phagocytic function of neutrophils, and cytokine concentration in broiler chickens. A total of 240 one-day-old Arbor Acres male broilers were randomly assigned to four treatments with six replicate pens of 10 broiler chickens per pen. Broiler chickens were fed diets based on four levels of dietary ORI (0, 50, 80 and 100 mg/kg) for a 42-d feeding trial...

Moringa oleifera is used in traditional medicine as well as in food, cosmetic, and pharmaceutical industries. Water-soluble M. oleifera lectin (WSMoL) is an anionic protein isolated from the seeds. This work investigated the immunomodulatory effects of WSMoL on human PBMC. Measurement of cytokine and nitric oxide levels and immunophenotyping assays were investigated. PBMC were incubated with WSMoL (10 µg/mL) for 24 h, 48 h and 72 h, and was performed immunophenotyping of lymphocytes and monocytes. Culture supernatants were used to determined cytokine and nitric oxide levels...

COPD is associated with high morbidity and mortality and no effective treatment is available till date. We have previously reported that PARP-1 plays an important role in the establishment of airway inflammation associated with asthma and ALI. In the present work, we have evaluated the beneficial effects of PARP-1 inhibition on COPD pathogenesis utilizing elastase induced mouse model of the disease. Our data show that PARP-1 inhibition by olaparib significantly reduced the elastase-induced recruitment of inflammatory cells particularly neutrophils in the lungs of mice when administered at a dose of 5 mg/kg b...

BACKGROUND: Cataracts occur earlier among HIV-infected adults and this is attributed to various intraocular inflammatory processes that result in early degeneration. In this study we purposed to investigate whether HIV infected individuals with cataracts develop heightened intraocular inflammatory processes compared to their HIV negative counterparts by determining the concentration of 8 cytokines in the aqueous humour of HIV-positive adults with cataracts and their HIV-negative counterparts...

The purpose of the present study was to compare the levels of tumor necrosis factor a (TNF-a), and interleukins (IL) 1, 6, 8 and 10 in the umbilical cord and neonatal circulation among neonates with early and late cord clamping MATERIAL AND METHODS: A consecutive series of 76 cases that had an uncomplicated pregnancy and an uneventful parturition was evaluated. In 40 cases delayed cord clamping was used and in the remaining 36 cases early cord clamping was practiced. Blood samples were collected from the umbilical vein immediately after cord clamping and at 24 hours from the median cubital or basilic vein of the neonate RESULTS: Significant differences were noted in the hematocrit and hemoglobin levels at 24 hours that favored delayed clamping...
