The nature of gene mutations induced by ionizing radiation in germ cells and transmitted to offspring remains one of the most important problems in radiation genetics of higher eukaryotes. The data accumulated in this field were obtained by different authors under different experimental conditions which does not give a complete insight about the nature of radiation-induced inherited mutations at different genome levels (chromosome, gene, DNA). 

It is now well accepted that the ionizing radiation-generated reactive oxygen species (ROS), that constitute ~2/3 of the effects of external beam radiation, do not only produce direct tumor cell death, but also affect the surrounding microenvironment. Moreover, this indirect effect of radiation may result in systemic effects, specifically the initiation of an inflammatory response.

Infectious diseases caused by microorganisms of the most varied natures and by viral entities cause millions of deaths every year. Around the world, viral infections have impacted civilizations’ circumstances since the earliest times, including the current panorama of the SARS-CoV-2 pandemic known as coronavirus disease in 2019 (COVID-19). In this sense, in the last century,

Delivery of high-quality cancer care improves oncologic outcomes, including survival and quality of life. The VA National Radiation Oncology (NROP) established the VA Radiation Oncology Quality Surveillance Program (VAROQS) which has developed clinical quality measures (QM) as a measure of quality indices in radiation oncology. We sought to measure quality in community care, assess barriers to data capture, and develop solutions to ensure long term sustainability of continuous quality improvement for veterans that receive dual care, both within the VA and in non-VA community care (NVCC).

Lung cancer remains the leading cause of cancer related death in the United States with mortality rates surpassing breast, prostate, brain, and colorectal cancers combined. Recent data shows that susceptibility for both men and women for developing invasive lung and bronchogenic carcinoma peak after the age of 70 years.

Worldwide, obesity is a public health concern and a metabolic ailment characterized by excessive adipose tissue accumulation resulting from an imbalance of energy expenditure and energy intake [1]. This disorder is a known risk factor for cardiovascular disease, type 2 diabetes mellitus, dyslipidemia, hypertension, and metabolic

Verrucous carcinoma of the esophagus (VCE) is a rare variant of esophageal squamous cell carcinoma. Most cases of VCE presents as an exophytic, slow-growing mass with a superficial growth pattern. Even when VCE exhibits a characteristic pattern during an endoscopic examination, it is very difficult to make a definitive diagnosis of VCE preoperatively, because biopsy specimens are
only characterized by nonspecific acanthosis and hyperkeratosis or parakeratosis associated with inflammation.

Severe acute respiratory syndrome coronavirus 2 (SARSCoV- 2) is a positive-sense, single-stranded RNA with genome size 26.2, and 31.7 kb coronavirus, covered by an enveloped structure, which is a major source of disaster in the 21st century. A typical CoV contains at least six ORFs in its genome. SARS-CoV-2 is the seventh coronavirus that is known to cause human disease.

The Corona Virus disease is a severe respiratory problem generated via severe acute respiratory syndrome coronavirus 2 (SARS CoV-2). The latest strain of the disease was deadly enough to halt the global routines of human development. In this context, a number of research studies have been conducted to provide knowledge and to combat with this severe illness.

A panel of 4 different cell lines was optimized for isolation, identification, and authentication of a varicella zoster virus from a swab sample of an 8-year-old boy suspected to varicella zoster infection. The system enabled highly efficient and rapid isolation of viruses in 33°C by serial sub culturing to more than 25 passages. The technique relies on isolation of viral genes by increasing the number of particles that are statistically represented in cell culture and verified by cell culture infectious dose 50% assay

The role for postoperative radiation therapy (PORT) for patients with non–small-cell lung cancer (NSCLC) with mediastinal lymph node (LN) involvement (pN2 disease) is controversial. We performed a SEER analysis comparing surgery alone with PORT among patients with pN2 NSCLC. As we await the final results of the LUNG ART trial, a subset of patients with a high LN positive to sampled (LPR) ratio may benefit from PORT.

Highly-Active Antiretroviral Therapy (HAART) is the recommended treatment and management strategy for HIV infection. Although the existing antiretroviral drugs are indispensably significant in improving the quality and extending the lives of HIV/ AIDS individuals, the drugs still have many limitations including development of resistance, production of toxicity, and their limited availability. 

Although being a complex pathology with genetic as well as non-genetic etiologies, cancer is characterized by a limited series of hallmarks including energetic metabolism reprogramming.

Plant virus nanoparticles (PVNPs) are increasingly recognized and studied for use in biomedical applications. PVNPs include plant virions with self-assembled capsid protein coats (PC) that encapsulate the virus genome, and virus-like particles (VLPs), a capsid without the viral genome.

Respiratory syncytial virus (RSV) is the most common cause of bronchiolitis. It is a single-stranded RNA virus of the Paramyxoviridae family that is transmitted through nasopharyngeal or conjunctival mucosa from infected individuals. The incubation period ranges from 2 to 8 days. Two antigenically different RSV subtypes exist, A and B. 

We recently reported that influenza infection is associated with drastic, depot-specific changes in white adipose tissue (WAT), notably the occurrence of thermogenic brown-like adipocytes within the subcutaneous depot, a process referred to as WAT browning. In mammals, induction of the thermogenic circuit increases heat production and consumes energy, consequently improving host’s metabolism.

Leveraging the immunomodulatory effects of radiation therapy (RT) for synergy with immunotherapeutic agents for the treatment of cancer is an area of immense interest. A pressing deficiency in the translation of this strategy into the clinic is the lack of clarity on the impact of radiation dose-fractionation on host anti-cancer immune defences.

Tenofovir disoproxil fumarate (TDF) is one of the main antiretroviral drugs of people living with human immunodeficiency virus (PLWHIV). Despite its efficacy and tolerability, there is conflicting evidence regarding TDF-associated nephrotoxicity, which is proposed to cause injury by accumulation of tenofovir (TFV) within proximal tubular cells leading to mitochondrial injury and tissue hypoxia. 

Titanium dioxide (TiO2 ) based nano-sized photocatalysts (NPCs) were synthesized following a green method from the extract of Peepal (Ficus religiosa) leaves and titanium tetrachloride as precursors. Doping of TiO2 with Magnesium (Mg) was done using magnesium chloride through the method of chemical precipitation. Size of the NPC samples were estimated and characterized by CPS Disc Centrifuge, Diffracted Light Scattering (DLS) and Field Emission Gun Scanning Electron Microscopy (FEG-SEM) techniques.

An indirect enzyme-linked immunosorbent assay (iELISA) was established to detect the serological prevalence of bluetongue virus (BTV) infection in ruminant populations. A recombinant NS4 (rNS4) protein was used as the encapsulated antigen. Optimization of the iELISA included the encapsulated antigen, serum dilution, blocking solution, and working concentration of a horseradish peroxidase (HRP)-labeled secondary antibody (Ab) by the square-matrix titration test.
