Dosimetric and radiobiological comparison between conventional and hypofractionated breast treatment plans using the Halcyon system.

Purpose: The objective of this research is to compare the efficacy of conventional and hypofractionated radiotherapy treatment plans for breast cancer patients, with a specific focus on the unique features of the Halcyon system.

Methods And Materials: The study collected and analyzed dose volume histogram (DVH) data for two groups of treatment plans implemented using the Halcyon system. The first group consisted of 19 patients who received conventional fractionated (CF) treatment with a total dose of 50 Gy in 25 fractions, while the second group comprised 9 patients who received hypofractionated (HF) treatment with a total dose of 42.

Retroperitoneal ectopic pregnancy after fertilization: A case report of a patient with bilateral salpingectomy.

Retroperitoneal ectopic pregnancy (REP) is a rare obstetric condition caused by the mislocalization of the gestational mass. The unexpected location often results in missed or delayed diagnoses, which can complicate the treatment process. We report the case of a 34-year-old Asian woman who presented to the hospital 31 days after embryo transfer with mild vaginal bleeding.

GAMMA SPECTRUM STABILIZATION FOR ENVIRONMENTAL RADIATION MONITORING STATIONS USING NAI(TL) DETECTOR.

Gamma spectrum measured by an NaI(Tl) detector is known to be unstable with the in situ temperature. In the present work, an advanced method has been applied to stabilize the gamma spectrum measured by the NaI(Tl) detector at environmental radiation monitoring (ERM) stations. The method is based on experimental data obtained under controlled conditions in laboratory.

extract inhibits hepatocellular carcinoma via induction of caspase-dependent apoptosis.

Introduction: Cancer is a disease with a global burden and is a major and increasing threat to public health. The demand for new modalities to treat and prevent cancer is high. Given the toxic side effects of standard treatments, such as chemotherapy, there is greater research interest in naturally derived compounds due to their selective toxicity to cancer cells.

Cytotoxic activity of new phenolic compounds from Vietnamese Caesalpinia sappan.

Two new phenolic compounds, caesalpiniaphenols G-H (1 and 2), were isolated from Vietnamese Caesalpinia sappan heartwood. The chemical structures were established mainly by extensive spectroscopic studies and chemical evidence. Compounds 1 and 2 showed potent inhibitory activity against HL-60 cancer cell lines with respective IC50 values of 16.
