The effect of aliphatic, naphthenic, and aromatic hydrocarbons on production of reactive oxygen species and reactive nitrogen species in rat brain synaptosome fraction: the involvement of calcium, nitric oxide synthase, mitochondria, and phospholipase A.

This study investigated the effects of C7 and C9 aliphatic (n-heptane, n-nonane), naphthenic (methylcyclohexane, 1,2,4-trimethylcyclohexane (TMCH)) and aromatic (toluene, 1,2,4-trimethylbenzene (TMB)) hydrocarbons on the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in rat brain synaptosome fraction. Methyl mercury (MeHg) was included as a positive control. Exposure of the synaptosomes to the hydrocarbons produced a concentration-dependent linear increase in the formation of the fluorescence of 2',7'-dichlorofluorescein (DCF) as a measure of the production of

Marginal resection of solitary plasmacytoma in the anterior region of the mandible and dental implant rehabilitation: Report of an unusual case.

INTRODUCTION: Plasmacytoma describes a neoplastic proliferation of plasma cells affecting different groups of patients according to location, and may demonstrate heterogeneous tumor progression and survival rate. The present article describes a case of solitary plasmacytoma in the mandible. PRESENTATION OF CASE: A 57-year-old male smoker was referred to the oral and maxillofacial service with extensive injury, approximately 4-5 cm in size, involving the anterior inferior region of mandible. After confirming diagnosis of plasmacytoma through incisional biopsy, because it was a recurrent lesion

Activation of the steroid and xenobiotic receptor (human pregnane X receptor) by nontaxane microtubule-stabilizing agents.

PURPOSE: Because induction of drug efflux transporters is one of the major underlying mechanisms of drug resistance in cancer chemotherapy, and human pregnane X receptor (hPXR) is one of the principal "xenobiotic" receptors whose activation induces transporter and drug-metabolizing enzyme gene transcription, it would be ideal to develop chemotherapy drugs that do not activate hPXR. This report describes studies undertaken to explore the characteristics of hPXR stimulation and mechanisms of drug-receptor interactions in vitro with new anti-tubulin drugs. EXPERIMENTAL DESIGN: In vitro transient

Integrating CRISPR/Cas technology with clinical trials: Principles, progress and challenges.

CRISPR represent a groundbreaking genome-editing technology that has revolutionized genetic modification. This innovative tool offers an unparalleled revolution in the future treatment of genetic disorders, neurological diseases, infectious diseases and cancer. Despite the rapid expansion of CRISPR applications, its clinical use in humans is still relatively limited, with only 69 active clinical trials and 6 completed studies reported so far. This review examined current clinical trials and their processes in addressing various diseases via the CRISPR/Cas system. While earlier literatures have

Cytokine release syndrome and tumor lysis syndrome in a multiple myeloma patient treated with palliative radiotherapy: A case report and review of the literature.

UNLABELLED: We present the case of a 53-year-old woman treated with analgesic radiotherapy for a multiple myeloma bone lesion of the forearm. After a first fraction of 5 Gray (Gy), she presented with an acute respiratory syndrome with fever a few hours after the treatment. The same symptoms occurred after the second fraction 3 days later. The patient recovered quickly thanks to intravenous hydration and suspension of the radiotherapy. Biological tests revealed a tumor lysis syndrome. We concluded that the clinical symptoms could be defined as cytokine release syndrome. This is the second time

The deubiquitinase USP34 stabilizes SOX2 and induces cell survival and drug resistance in laryngeal squamous cell carcinoma.

Recent studies showed that the deubiquitinase ubiquitin-specific protease 34 (USP34) was involved in the tumorigenesis of several tumors, but its function and mechanism are still unclear in laryngeal squamous cell carcinoma (LSCC). In this study, we found that USP34 and SOX2 were elevated in LSCC tumor tissues, and we also found that USP34 expression was positively correlated with SOX2 expression. Our further studies showed that USP34 regulated the protein level of SOX2 in LSCC cells, but not the mRNA level, which suggested that USP34 stabilized SOX2. Moreover, USP34, as a deubiquitinase, coul

Структура и состав микробных сообществ в водной толще Южного залива Мексики и обнаружение предполагаемых микроорганизмов, деградирующих углеводороды.

В ходе этого исследования была проведена оценка сообщества бактериопланктонов и его связи с экологическими переменными, включая общую концентрацию нефтяных углеводородов (ТПГ), в районе шельфа Юкатан в Южном заливе Мексики. Анализ разнообразия бета на основе последовательности 16S rRNA показал различия в структуре общины бактериопланктона между участками отбора проб. ПЕРМАНОВА указала, что эти изменения могут быть связаны главным образом с глубокими изменениями (см.5 в адрес 180 m), концентрация растворенного кислорода (2.06 в адрес 5.93 мг L-1), и концентрация хлорофилла (0.184 в адрес 7.65 м

Development and application of decatungstate catalyzed C-H 18F- and 19F-fluorination, fluoroalkylation and beyond.

Over the past few decades, photocatalytic C-H functionalization reactions have received increasing attention due to the often mild reaction conditions and complementary selectivities to conventional functionalization processes. Now, photocatalytic C-H functionalization is a widely employed tool, supporting activities ranging from complex molecule synthesis to late-stage structure-activity relationship studies. In this perspective, we will discuss our efforts in developing a photocatalytic decatungstate catalyzed C-H fluorination reaction as well as its practical application realized through co
