An Analysis of Radiotherapy Machine Requirements in India: Impact of the Pandemic and Regional Disparities.

Aim: This article examines India's present radiotherapy (RT) machine status and requirements, geographical distribution, and infrastructure need in six regional areas, which include 31 member states and union territories (UTs). It also considers the influence of the COVID-19 pandemic on India's teletherapy sector.

Materials And Methods: Data from reliable resources, including Atomic Energy Regulatory Board, Global Cancer Observatory, and Directory of Radiotherapy Centres databases, were used to analyze the current status of RT machine (RTM) density, regional disparity, and COVID-19 impact on infrastructure growth-rate.

Analyzing Global Cancer Control: Progress of National Cancer Control Programs through Composite Indicators and Regression Modeling.

Aim: Cancer is a significant public health concern, and National Cancer Control Programs (NCCPs) are crucial for reducing its burden. However, assessing the progress of NCCPs is challenging due to the complexity of cancer control outcomes and the various factors that influence them. Composite indicators can provide a comprehensive and accurate assessment of NCCP progress.

Precursor engineering for soft selective synthesis of phase pure metal-rich digenite (CuS) and djurleite (CuS) nanocrystals and investigation of their photo-switching characteristics.

Copper sulfide nanostructures have evolved as one of the most technologically important materials for energy conversion and storage owing to their economic and non-toxic nature and superior performances. This paper presents a direct, scalable synthetic route aided by a single source molecular precursor (SSP) approach to access copper sulfide nanomaterials. Two SSPs, CuX(dmpymSH)(PPh) (where X = Cl or I), were synthesized in quantitative yields and thermolyzed under appropriate conditions to afford the nanostructures.

Customizing Treatment Scheduling Windows with a Time Margin Recipe: A Single-institutional Study.

Purpose: Rising cancer incidences, complex treatment techniques, and workflows have all impacted the radiotherapy scheduling process. Intelligent appointment scheduling is needed to help radiotherapy users adapt to new practices.

Materials And Methods: We utilized van Herk's safety margin formula to determine the radiotherapy department's treatment scheduling window (TSW).

Efficient and Reliable Data Extraction in Radiation Oncology using Python Programming Language: A Pilot Study.

Background And Purpose: In recent years, data science approaches have entered health-care systems such as radiology, pathology, and radiation oncology. In our pilot study, we developed an automated data mining approach to extract data from a treatment planning system (TPS) with high speed, maximum accuracy, and little human interaction. We compared the amount of time required for manual data extraction versus the automated data mining technique.

Molecular precursor-mediated facile synthesis of photo-responsive stibnite SbS nanorods and tetrahedrite CuSbS nanocrystals.

Stibnite SbS and tetrahedrite CuSbS nanostructures being economical, environmentally benign and having a high absorption coefficient are highly promising materials for energy conversion applications. However, producing these materials especially tetrahedrite in the phase pure form is a challenging task. In this report we present a structurally characterized single source molecular precursor [Sb(4,6-MepymS)] for the facile synthesis of binary SbS as well as ternary CuSbS in oleylamine (OAm) at a relatively lower temperature.

An audit of Grade III or more skin reactions in consecutively assessed patients at a modern radiation oncology center.

Purpose: Radiation dermatitis is most common and debilitating side effects of radiotherapy leading to treatment interruption, thereby compromising the local control, and effecting quality of life. With the invent of modern imaging and recent advances in megavoltage radiotherapy, radiation-related side effects have reduced. In this audit, we report the risk factors associated with Grade III dermatitis in modern centers.

A mathematical formulation for volume expansions in contouring for radiotherapy planning.

Materials And Methods: Settings and Design - Spheres of diameter (0.

Electronic Structures of Mono-Oxidized Copper and Nickel Phosphasalen Complexes.

Non-innocent ligands render the determination of the electronic structure in metal complexes difficult. As such, a combination of experimental techniques and quantum chemistry are required to correctly elucidate them. This paper deals with the one-electron oxidation of copper(II) and nickel(II) complexes featuring a phosphasalen ligand (Psalen), which differs from salen analogues by the presence of iminophosphorane groups (P=N) instead of imines.

Clinical correlates of leukoaraiosis: A study of 175 patients.

Background: In India, the correlates of leukoaraiosis (LA) have not been widely reported. This study was designed to investigate the factors which correlate with LA.

Materials And Methods: We included patients with LA who consented for the study and graded their severity on the basis of Fazekas scale.

Preparation of fenofibrate solid dispersion using electrospray deposition and improvement in oral absorption by instantaneous post-heating of the formulation.

A coaxial electrospray technique was applied to a poorly soluble drug, fenofibrate (FEN), to increase its bioavailability. A particulate core-shell solid dispersion was designed using poly(methacrylic acid-co-methyl methacrylate) (Eudragit L-100) as a shell material and poly(vinyl pyrrolidone) K12-17 as a dispersant for FEN in the core phase. Although 58% of FEN remained in the crystalline state in the electrosprayed formulation, the dissolution behavior was significantly improved due to decrease in particle size, decrease in crystallinity, and increase in dispersion efficiency.

Reactivity of 2-chalcogenopyridines with palladium-phosphine complexes: isolation of different complexes depending on the nature of chalcogen atom and phosphine ligand.

Reactions of either Pd(0) phosphine complexes with dipyridyldichalcogenides or [PdCl2(P∩P)] (P∩P = dppe, dppp) with pyridylchalcogenolate ions have been examined and a variety of Pd(II) complexes have been isolated and characterized. Oxidative addition of {SeC5H3(3-R)N}2 (R = H or Me) to [Pd(P∩P)2] (P∩P = dppe, dppp) gave either a mononuclear complex, [Pd{2-Se-C5H3(3-R)N}2(P∩P)] (for P∩P/R: dppe/H or Me; dppp/H) or a cationic binuclear complex, [Pd2{μ-SeC5H3(3-Me)N}2(dppp)2]2+ (4b) (R = Me) whereas reactions involving the tellurium analogue exclusively afforded trinuclear complexes, [Pd3(μ-Te)2(P∩P)3]Cl2 (P∩P = dppe (2) or dppp (6)). The latter was also obtained in the substitution reaction between [PdCl2(P∩P)] and NaTeC5H3(3-R)N.

Tellurium(0) as a ligand: synthesis and characterization of 2-pyridyltellurolates of platinum(II) and structures of [Pt{2-Te-3-(R)C5H3N}2Te(PR'3)] (R = H or Me).

Treatment of toluene solutions of the ditellurides [Te(2){C(5)H(3)N(R)-3}(2)] (R = H or Me) with [Pt(PPh(3))(4)] yielded two types of complexes, [Pt{2-Te-3-(R)C(5)H(3)N}(2)(PPh(3))(2)] (1a-d) as the major products and [Pt{2-Te-3-(R)C(5)H(3)N}(2)Te(PPh(3))] (2a-d) as minor products. The above complexes can also be obtained by the reaction of [PtCl(2)(PR'(3))(2)] (PR'(3) = PPh(3) or PPh(2)(2-C(5)H(4)N)) with 2 equiv of Na(2-Te-C(5)H(3)R). The complexes were characterized by elemental analyses and UV-vis, NMR ((1)H and (31)P), and (in part) XPS spectroscopy.
