Oncolytic properties had been demonstrated in Mammalian Orthoreovirus (MRV) and Avian Orthorevirus (ARV). Besides MRV and ARV, Pteropine Orthoreovirus (PRV) is also categorized under the genus

PRV7S (Sikamat virus) is an orthoreovirus isolated in Malaysia. Present study aims to investigate the oncolytic effects of PRV7S on ranges of nasopharyngeal carcinoma (NPC) cells through apoptosis in comparison to MRV3.

Non-cancerous nasopharyngeal (NCNP) and NPC cells were infected by PRV7S and MRV3. The effects of PRV7S on the proliferation inhibition and apoptotic activity of NPC cells was examined using MTT assay and flow cytometry. Additionally, western blot assay was performed to analyze the expression of RAS and apoptotic protein. Lastly, qPCR assay was performed to demonstrate that PRV7S and MRV3 replicated in infected-NPC and infected-NCNP cells.

The proliferation of NPC cells were significantly inhibited after PRV7S infection in a time dependent manner in comparison to infected-NCPC cells. Flow cytometry analysis showed that PRV7S infection was able to induce apoptosis on NPC cells at 48 hpi. Western blot results showed that upon PRV7S infection, N/H/K RAS protein expression was reduced, whereas caspase-3 protein expression increased in NPC cells. qPCR assay showed higher viral load of PRV7S found in infected-NPC compared to infected-NCNP cells.

PRV7S inhibits the proliferation and induces apoptosis of NPC cells similar to MRV3. Therefore, PRV7S is a potential oncolytic virus.

Cancer is a representative geriatric disease closely related to senescent cells and cell aging in tissues. EN460 chemical structure Senescent cells that surround cancer tissues reduce the effects of various cancer treatments and induce cancer recurrence through senescence-associated secretory phenotype (SASP) secretion. Thus, for good therapeutic effect, candidate drugs should be selective for both cancer and senescent cells. In this study, we investigated the selective effect of piperine as a potential senostatic agent as well as an anticancer drug.

The effect of piperine on cytotoxicity and cell proliferation was tested by lactate dehydrogenase (LDH) or water-soluble tetrazolium salt (WST) assay. The levels of p16INK4a and p21, mitogen-activated protein kinases (MAPKs), and mammalian target of rapamycin (mTOR) were analyzed by Western blot analysis. The rejuvenation effects of piperine on the senescent cells were investigated by senescence-associated beta-galactosidase (SA-β-Gal) stain, mitochondria membrane potential (MMP) ande existing senostatics for cancer treatment.

The proximity of craniopharyngiomas (CPs) to critical neurovascular structures can lead to a host of neurologic and endocrine complications that lead to difficulty with surgical management. In this review, we examine the molecular and genetic markers implicated in CP, their involvement in tumorigenic pathways, and their impact on CP prognosis and treatment.

We undertook a focused review of relevant articles, clinical trials, and molecular summaries regarding CP.

Genetic and immunological markers show variable expression in different types of CP.

is implicated in tumorigenesis in papillary CP (pCP), whereas

and

are often overexpressed in adamantinomatous CP (aCP) and

is overexpressed in aCP and recurrent CP. Targeted treatment modalities inhibiting these pathways can shrink or halt progression of CP. In addition,

inhibitors may sensitize tumors to radiation therapy. These drugs show promise in medical management and neoadjuvant therapy for CP. Immunotherapy, including anti-interleukin-6 (IL-6) drugs and interferon treatment, are also effective in managing tumor growth. Ongoing clinical trials in CP are limited but are testing BRAF/MET inhibitors and IL-6 monoclonal antibodies.

Genetic and immunological markers show variable expression in different subtypes of CP. Several current molecular treatments have shown some success in the management of this disease. Additional clinical trials and targeted therapies will be important to improve CP patient outcomes.

To compare the progression of neovascular remodeling and subretinal fibrosis in neovascular age-related macular degeneration (NVAMD) after anti-vascular endothelial growth factor (VEGF) therapy.

Twenty eyes from 20 patients with subretinal fibrosis complicating NVAMD were retrospectively reviewed. All patients complied with at least three consecutive monthly intravitreal treatments and final follow-up visit at 12 months after the initial anti-VEGF treatment of aflibercept or ranibizumab. Using optical coherence tomography angiography (OCTA), the central macular thickness (CMT), microvascular density in the superficial capillary plexus (SCP), deep capillary plexus (DCP), choroidal neovascularization (CNV) lesions, as well as subretinal fibrotic lesions were compared between baseline and final visit.

The mean number for anti-VEGF injections was 4.40 ± 0.88 during the 12 months of follow-up. There was no significant difference in best-corrected visual acuity (BCVA) and vascular density in SCP and DCP (

0ith NVAMD. Subretinal fibrosis complicating NVAMD remains a major obstacle for the management of NVAMD, and anti-VEGF treatment is a potential therapeutic strategy to target neovascular remodeling and subretinal fibrosis as either an additive or alternative therapeutic approach for NVAMD.Polyphenols, members of phytochemical superfamily rich in vegetables and fruits, include flavonoids, non-flavonoids, and phenolic acids. Their biological effects includes classical antioxidation (e.g., radical-scavenging, metal chelating, NOX inhibition, attenuation on mitochondrial respiration, inhibition on xanthine oxidase, and upregulations on endogenous antioxidant enzymes), multiple regulations on cell signaling (e.g., AMPK activation, SirT1 activation, eNOS activation, FOXO activation, NFκB inactivation, PI3K/AkT inhibition, mTORC1 inhibition, PKC inhibition, MAPK inhibition, ERK inhibition, JAK/STAT inhibition, IKK/JNK inhibition, PDE inhibition, β-catenin inactivation, downregulation on TLR expression, ACE inhibition, adiponectin elevation, attenuated ET-1 production, and K+ channel activation), and many other actions (e.g., inhibition on α-glucosidase, anticoagulation, γ-secretase inhibition, monoamine oxidase inhibition, LPL upregulation, ANGPTL4 suppression, upregulation on paraoxonase 1, PAI-1 downregulation, tPA upregulation, immunoregulation, epigenetic modulation, and altered gut microbiota). Such multi- targeting and functions exhibiting antioxidative stress and antiinflammation as major pillars along with many other antagonisms could not only afford healthy polyphenols suitable supplements for promoting health, but also advance them to therapeutic applications. This review aims to translate diverse polyphenolic biochemical actions to clinical applications in fighting against non-communicable diseases such as CVD, cancer, diabetes, obesity, neurodegeneration, inflammatory diseases (e.g., IBD, IBS, NAFLD, etc.), AMD, allergy, and autoimmunity as well as communicable infection (e.g., bacteria, fungal, and viral).

Tumor necrosis factor (TNF) plays an important role in immune responses to the causative agent of tuberculosis,

. Additionally, TNF can also mediate many negative disease manifestations. The aim of this study was to assess the contribution of anti-TNF autoantibodies to the pathogenesis of active pulmonary tuberculosis (TB).

The levels of anti-TNF autoantibody classes and subclasses were determined by applying enzyme-linked immunosorbent assays (ELISAs). The levels of TNF and of its soluble receptors were also evaluated using commercial ELISA kits.

The levels of both types of soluble TNF receptors were lower patients with TB than in healthy donors. Patients with TB had higher titers of immunoglobulin (Ig)G class and IgG3 subclass anti-TNF autoantibodies in comparison with healthy donors. Patients who had a disseminated TB infection had higher TNF level and IgG, IgG1 and IgG3 autoantibody titers compared with patients who had a localized TB infection.

Changes in the titers of anti-TNF autoantibody classes and subclasses were noted in patients with TB, suggesting their possible contribution to the disease pathogenesis of TB.

Cumulative evidence suggests that the risk of eye tumors varies among different age groups and populations. The purpose of the present study was to assess the age distribution of eye tumors in China.

In this retrospective study, the age distribution of various types of eye tumors was analyzed on surgically excised and histologically confirmed specimens obtained from 4492 patients (4526 eyes), collected between 2001 and 2017.

Of the 4526 specimens, 3156 eyes (69.7%) had benign eye tumors, while 1370 eyes (30.3%) had malignant tumors. The age-specific incidence of eye tumors was characterized by a bimodal distribution, one peak occurred at age 0-9 years (19.7%) and the other at 50-59 years (14.7%) of age. Malignant eyelid tumors were very rare under the age of 20 years, but increased to 78% of all eyelid tumors by the age of 70 years. Children aged 0-9 years old were 6.5 times as likely to have a malignant eye tumor (95% CI, 4.1-10.4) as those aged 10-19 years. The age-related variation of eye tumors was also observed in the top ten categories of both benign (

< 0.001) and malignant types (

= 0.001).

These results showed that age is a major factor determining the type of eye tumor, confirmed by histopathological analysis.

The defect of intervertebral disc (IVD) after discectomy may impair tissue healing and predispose patients to subsequent IVD degeneration, which is thought to be an important cause of recurrence. Cell-based approaches for the treatment of IVD degeneration have shown promise in preclinical studies. However, most of these therapies have not been approved for clinical use due to the risks of abnormal differentiation and microorganism contamination of the culture-expanded cells. Selective cell retention (SCR) technology is non-cultivation technique, which can avoid those preambles in cell expansion. In this study, we used a commercially available BONE GROWTH PROMOTER device (BGP, FUWOSI, Chongqing, China) to concentrate mesenchymal stromal cells (MSCs) from bone marrow aspirate (BMA) through SCR technology.

A small incision was made on the L2/3, L3/4 and L4/5 discs of goats and part of nucleus pulposus (NP) was removed to construct IVD defect model. The L2/3 disc was subjected to discectomy only (DO group), the L3/4 disc was implanted with enriched BMA-matrix (CE group), and the L4/5 disc was implanted cultured autologous bone marrow MSCs matrix (CC group).
