BACKGROUND: The incidence of colorectal cancer (CRC) in individuals of fertile age is increasing. Oxaliplatin is a cornerstone treatment in the adjuvant setting for stage III and high-risk stage II CRC. Limited data exist on possible side effects of oxaliplatin on fertility and gonadal function. More data is needed to guide possible fertility preservation procedures and aid evidence-based fertilit

Optimal blood flow through a patent cerebral circulation is critical for supply of oxygen and nutrients for brain function. The integrity of vascular elements within arterial vessels of any calibre can be compromised by various disease processes. Pathological changes in the walls of veins and the venous system may also alter the dynamics of cerebral perfusion. The consequences of both systemic vas

Mitotic cells attenuate the DNA damage response (DDR) by phosphorylating 53BP1, a critical DDR mediator, to prevent its localization to damaged chromatin. Timely dephosphorylation of 53BP1 is critical for genome integrity, as premature recruitment of 53BP1 to DNA lesions impairs mitotic fidelity. Protein phosphatase 4 (PP4) dephosphorylates 53BP1 in late mitosis to allow its recruitment to DNA les

Deep eutectic solvents (DESs) have gained popularity in various applications due to their improved environmental sustainability and biodegradability. For the present study, several polyhydric alcohols, including ethylene glycol (EG), diethylene glycol (DEG), triethylene glycol (TEG), and glycerol (Gly), have been used as hydrogen bond donors (HBDs) and choline chloride (ChCl) as a hydrogen bond ac

Antimicrobial resistance is one of the largest threats to global health. In society as well as in healthcare facilities, antimicrobial resistance is rapidly increasing with the main reason being overuse and misuse of antibiotics combined with inadequate infection prevention. For humans, dental care accounts for about 10% of all antibiotic prescriptions, making it an important target for antibiotic

Metalloporphyrins on interfaces offer a rich playground for functional materials and hence have been subjected to intense scrutiny over the past decades. As the same porphyrin macrocycle on the same surface may exhibit vastly different physicochemical properties depending on the metal center and its substituents, it is vital to have a thorough structural and chemical characterization of such syste

This article seeks to explain the growth of identification and support for the Palestinian cause over the last decades from a regional concern to a global movement. What are the mechanisms that made this possible? This problematic is addressed within a cultural sociological framework, focusing on the cultural work of intellectuals and the collective actions of social movements in articulating and

AIM: To study the mechanism of 5-fluorouracil (5-FU) resistance in colon cancer cells and to develop strategies for overcoming such resistance by combination treatment.METHODS: We established and characterized a 5-FU resistance (5-FU-R) cell line derived from continuous exposure (25 μmol/L) to 5-FU for 20 wk in 5-FU sensitive HCT-116 cells. The proliferation and expression of different representat

This study was carried out in the forest area of the Gomel region of Belarus contaminated by 137Cs following the Chernobyl accident of 1986. The aim of the study was to explore the effects of different types of wildfires on the biological availability of radionuclides and the distribution of algal communities in fire-affected soils. Soil samples were collected in 2017 and 2018 from sites burnt by

Based on known heterocyclic topoisomerase II inhibitors and anticancer agents, various indenoindolone derivatives were predicted as potential topoisomerase II-inhibiting anticancer agents. They are hydrazones, (thio)semicarbazones, and oximes of indenoindolones, and indenoindolols. These derivatives with suitable substitutions exhibited potent specific inhibition of human DNA TopoIIα while not sho

We have previously reported that 4-(3-(tert-butylamino)imidazo[1,2-α]pyridine-2-yl)benzoic acid, a bicyclic N-fused aminoimidazoles derivative (BNFA-D), possesses anticancer potentiality against breast and kidney cancer cells with minimal toxicities to corresponding normal cells. Here, we explored the mechanism of action of BNFA-D in breast cancer cells using multiple cell-based assays such as MTT

Colorectal cancer (CRC) patients with APC mutations do not benefit from 5-FU therapy. It was reported that APC physically interacts with POLβ and FEN1, thus blocking LP-BER via APC's DNA repair inhibitory (DRI) domain in vitro. The aim of this study was to elucidate how APC status affects BER and the response of CRC to 5-FU. HCT-116, HT-29, and LOVO cells varying in APC status were treated with 5-

Forest fires are of special interest for Belarus because of radioactive contamination caused by the 1986 accident at the Chernobyl Nuclear Power Plant. This work aims to determine the potential activity of long-lived radionuclides in surface air caused by forest fires and to estimate the potential health threat to firefighters. The methodology is based on measurements of radioactivity released by

This article is part of the Dendritic Cell Guidelines article series, which provides a collection of state-of-the-art protocols for the preparation, phenotype analysis by flow cytometry, generation, fluorescence microscopy, and functional characterization of mouse and human dendritic cells (DC) from lymphoid organs, and various nonlymphoid tissues. Within this article, detailed protocols are prese

Scaffold hybridization of several natural and synthetic anticancer leads led to the consideration of indenoindolones as potential novel anticancer agents. A series of these compounds were prepared by a diversity-feasible synthetic method. They were found to possess anticancer activities with higher potency compared to etoposide and 5-fluorouracil in kidney cancer cells (HEK 293) and low toxicity t

We previously showed that quinacrine (QC), a small molecule antimalarial agent, also presented anticancer activity in breast cancer cells through activation of p53, p21, and inhibition of topoisomerase activity. Here we have systematically studied the detailed cell death mechanism of this drug using three colon cancer cell lines (HCT-116 parental, isogenic HCT-116 p53-/-, and HCT-116 p21-/- sublin

AIM: The authors have systematically investigated the anticancer potentiality of silver-based nanoparticles (AgNPs) and the mechanism underlying their biological activity in human colon cancer cells.MATERIALS & METHODS: Starch-capped AgNPs were synthesized, characterized and their biological activity evaluated through multiple biochemical assays.RESULTS: AgNPs decreased the growth and viabilit

An approach involving rational structural elaboration of the biologically active natural product diindolylmethane (DIM) with the incorporation of aminophosphonate and urea moieties toward the discovery of potent anticancer agents was considered. A four-step approach for the synthesis of DIM aminophosphonate and urea derivatives was established. These novel compounds showed potent anticancer activi

Cigarette smoking is a key factor for the development and progression of different cancers including mammary tumor in women. Resveratrol (Res) is a promising natural chemotherapeutic agent that regulates many cellular targets including p21, a cip/kip family of cyclin kinase inhibitors involved in DNA damage-induced cell cycle arrest and blocking of DNA replication and repair. We have recently show

Cigarette smoking is a crucial factor in the development and progression of multiple cancers including breast. Here, we report that repeated exposure to a fixed, low dose of cigarette smoke condensate (CSC) prepared from Indian cigarettes is capable of transforming normal breast epithelial cells, MCF-10A, and delineate the biochemical basis for cellular transformation. CSC transformed cells (MCF-1
