What is oncolytic virus
Recently, the development of molecular biotechnology allows modifications of viral genomes genetically and optimizes the transformation of available viruses with weak pathogenicity. These methods are used to enhance the oncolytic effect and reduce adverse reactions to maximize both efficacy and safety. Indeed, the oncolytic virus can stimulate a pro-inflammatory tumor environment by enhancing antigen recognition and robust immune responses. It overcomes the immune evasiveness and escape of malignant cells to eliminate the tumor cells.

What is oncolytic virus therapy
An oncolytic virus is a form of promising therapeutic tool for the treatment of malignant tumors, which uses viruses to selectively infect and kill tumor cells and further to induce or boost specific antitumor immunity. https://www.creative-biolabs.com/oncolytic-virus/definition-of-an-oncolytic-virus.htm
Reporter-encoding Oncolytic Virus
Oncolytic viruses encoding reporter genes utilized for in vivo molecular imaging are useful to locate the distribution of oncolytic viruses in pre-clinical tests. Optical detection methods mainly include green fluorescent protein (GFP), enhanced GFP (eGFP), discosoma red fluorescent protein (DsRed), and bioluminescence imaging (BLI), which utilizes luciferases. Reporter-encoding oncolytic viruses, including vaccinia virus, adenovirus, herpes simplex virus and vesicular stomatitis virus, allow accurate tracking of gene expression, tumor metastases, viral infection as well as assessment of gene therapy.

Pre-made Oncolytic VACV
Vaccinia virus can accommodate more than 30 kb of foreign DNA. Foreign genes can be stably integrated into the viral genome, resulting in efficient and long-term gene expression. The deletion of the viral genes of thymidine kinase (TK) and vaccinia growth factors (VGF) results in enhanced tumor-selectively and antitumor activity, and reduced virus virulence. https://www.creative-biolabs.com/oncolytic-virus/category-pre-made-oncolytic-vaccinia-virus-291.htm
Pre-made Oncolytic Vaccinia Virus
Oncolytic viruses are a class of antitumor agents that selectively kill tumor cells without affecting normal cells. Vaccinia virus (VACV) is a large, enveloped virus that is considered as the most potential live biotherapeutic agent because of its strong oncolytic efficacy and potent antigen presentation capability that can combine well with its natural oncolytic activities for cancer immunotherapy. Many types of modified vaccinia virus have been used for in vitro and in vivo studies, as well as clinical trials.https://www.creative-biolabs.com/oncolytic-virus/category-pre-made-oncolytic-vaccinia-virus-291.htm
Pre-made Oncolytic HSV
Partial deletion of the HSV gene results in superior packaging capacity of >30 kb foreign DNA with low toxicity as an expression vector. Multiple modified purified oncolytic herpes simplex virus (oHSV) products can avoid evading the host immune response and reduce toxicity by gene knock-out, such as ICP0, ICP4, ICP22, ICP27 or ICP47.https://www.creative-biolabs.com/oncolytic-virus/category-pre-made-oncolytic-herpes-simplex-virus-290.htm
Pre-made Oncolytic Herpes Simplex Virus
Oncolytic viruses are using for the treatment of cancer due to the specific antitumor activity in tumor cells. Herpes simplex virus (HSV) is a human neurogenic dsDNA virus that has the characteristic of life-long latent infection of neurons and allows for long-term transgene expression.https://www.creative-biolabs.com/oncolytic-virus/category-pre-made-oncolytic-herpes-simplex-virus-290.htm
Oncolytic Virus Delivery
Oncolytic viruses have the potential to powerfully and selectively kill cancer cells and have shown impressive efficacy in preclinical and clinical settings. However, their potential can be restricted by inefficient delivery into the complex tumor environment. Thus, the efficient delivery of oncolytic viruses remains a significant challenge in the field of oncology, limiting their therapeutic effect. https://www.creative-biolabs.com/oncolytic-virus/approaches-to-delivery-of-oncolytic-viruses.htm

Oncolytic Virus Application
Numerous viruses are being developed pre-clinically and clinically. An investigation of all registered clinical trials in 2017 demonstrates 78 interventional trials regarding OVs. This ability for near-universal therapeutic impact in cancer makes OVs a popular therapeutic tool. Today, both preclinical and early-stage clinical trials are intensively investigating the approach to improve oncolytic virotherapy.

Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.

Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.

Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.

Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

ABDOMINAL TRAUMA in pediatrics part one.
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
