ancer is one of the leading causes of death globally, second only to cardiovascular diseases. In India, it ranks fifth in terms of mortality rate. The incidence of cancer varies across different regions of India. This study focuses on the Kashmir region which is a valley located in the northern part of India. The aim is to analyze the dynamics of c...

Background One of the most common congenital conditions detected globally, congenital heart diseases, and CT techniques provide a high-quality and thorough presentation of heart anatomy, thoracic vasculature, and extracardiac structures, and hence, it is becoming a more popular non-invasive diagnostic imaging method for congenital heart disease. Th...

Personalized cancer nanomedicine has emerged as a transitional and transformative approach in the fight against cancer, transcending traditional treatments and marking a paradigm shift toward more effective, targeted, and patient-specific therapies. In this age of precision medicine, the one-size-fits-all model is proving inadequate for the complex...

Radiation therapy mediated by nanoparticles is a new and exciting area in cancer treatment that offers creative ways to maximize the therapeutic benefit of radiation while reducing adverse effects. An overview of the most recent developments, difficulties, and opportunities in the quickly changing field of radiation therapy using nanoparticle-based...

This study proposes a novel therapeutic model for cancer treatment with radiation therapy by analyzing the interactions among cancer, immune and healthy cells through a system of three ordinary differential equations. In this model, the natural influx rate of mature immune cells is assumed constant and is denoted by, a. The overall effect of radiat...

The anatomy of the transversus abdominis muscle and its aponeurosis is important in transversus abdominis release surgery. We studied the CT anatomy of the transversus abdominis muscle medial to the linea semilunaris at different levels in the abdomen and measured the thickness of this muscle. In this retrospective study, we analysed 150 abdominal...

Purpose: The AAPM Task Group (TG) reports 204 and 220 presented methods for evaluation of patient dose by announcing the SSDE. The TG reports provide the Size Specific Conversion factors that can be multiplied to CTDIvol to calculate the patient dose in terms of SSDE constructed from Deff (AAPM TG-204) and Dw (AAPM TG-220). Our study presents a com...

Introduction The purpose of the study was to determine forward-planned intensity-modulated radiotherapy which improves the sparing of organs at risk (OAR), heart, lungs, and contralateral breast, when compared with multi-field inverse-planned intensity-modulated radiation therapy (RT). The anatomy of the chest wall is curved, which makes it difficu...

Hyperthermia is a method of cancer treatment wherein the temperature of the tumor is increased to over 315 K (42 • C) for a specific duration, ultimately leading to cell death by inducing apoptosis or necrosis. Magnetic Particle Hyperthermia (MPH) is a non-invasive method of cancer treatment in which magnetic nanoparticles are introduced to the tum...

Background: Long term exposure to environmental radioactivity and the associated external exposure due to gamma emitting radionuclides have serious health effects particularly on cancer risk. Of course, the soil radioactivity depends on the underlying rocks and consequently, the soil type and the geographic conditions. Objectives: Evaluation of exc...

This article is my Ph. D research work.

Since the creation of the universe, natural radioactivity has been an integral part of our environment and all living things are living and have to live in a sea of radiations. The natural radioactivity is caused by γ activities of Lignite belt of the Kashmir valley, India using NaI(Tl) Gamma ray spectrometer. specific activity concentration of Ra...

An investigation has been carried out for various crystal parameters like homopolar gap (Eh), heteropolar gap (E c), average gap (Eg) and refractive index (n). These estimated values are used to calculate the ionicity of ternary chalcopyrite semiconductors. Based on the complex crystal chemical bond theory, the Moss formula which is for one type of...

The present study was aimed at the determination of specific activity of locally manufactured and commercially available five cement types used as building material in Kashmir valley, India by using a NaI concentrations in the different analyzed cement samples were found to vary from 44.4±0.81 to 51.02±2.3 55.78±2.81 brand were above the world aver...

A pilot study was carried out in and around lignite belt of Nichahoma, Kupwara, and Kashmir to establish baseline background radiation data and to ascertain the radiological health hazards due to natural background radiation. The radiometric analyses were performed for the three different types of the samples: lignite (LG) samples, soil of the lign...

The measurements of activity concentrations in soil of the lignite belt and soil of the villages surrounding the lignite belt have been carried out in order to present the radiological health hazards due to gamma radiation levels of the soil to general public.
