Introduction: Diabetes is associated with an increased risk of cancer. Because of the metastatic nature of cancer, the survival of women with breast cancer is decreasing despite receiving various treatments such as chemotherapy, radiotherapy, etc. The aim of this study was to investigate the relationship between diabetes and the risk factors related to the survival of breast cancer patients. M...

background neuroblastoma is the most common extracranial malignant solid tumor in children under 5 years, and it is characterized by wide clinical and biological heterogeneity. n-myc oncogene amplification is considered to be one of the most important prognostic factors used to evaluate survival in these patients. objectives the aim of our study was to determine amplification of the n-myc oncog...

to survive in natural waters, bacteria must respond to a variety of environmental variables such asstarvation. flexibacter chinensis was grown and multiplied in the starvation medium and its viable count, totalcount and cell size were investigated under different temperatures. also, the effects of different nutrientsources were investigated. the survival of the organism under starvation conditi...

Background and aims: The pandemic of AIDS is a global emergency and one of the biggest challenges in social and individual life. This study aimed to evaluate the survival time of HIV patients and its effective factors. Methods: This historical cohort study was conducted on the individuals infected with HIV in Fars province, south of Iran, during 2006 to 2...

introduction: linguatula serrata is a zoonotic parasite, belonging to the class pentastomida. the major aim of this study was to evaluate the impact of sodium chloride (nacl) and heat on survival time of linguatula serrata nymphs. materials & methods: thirty nymphs (10 in triplicate) were separately transferred to plastic tubes, containing different concentrations of nacl solution (2%, 5% and 1...

In this work we set up the generating function of ultimate time survival probability $\varphi(u+1)$, where $$\varphi(u)=\mathbb{P}\left(\sup_{n\geqslant 1}\sum_{i=1}^{n}\left(X_i-\kappa\right)<u\right)$$ and $u\in\mathbb{N}_0,\,\kappa\in\mathbb{N}$, random walk $\left\{\sum_{i=1}^{n}X_i,\,n\in\mathbb{N}\right\}$ consists independent identically distributed variables $X_i$, which are non-negativ...

the relationship between the way in which normal hemopoietic stem cells respond to irradiation alone or in the presence of bleomycin sulfate (blm-s) and actinomycin 0 (act-d) was investigated. single doses of blm-s at 0.3 mg/kg and act-o at 0.10 mg/kg body weight were injected intravenously 1-6 hours prior to whole body irradiation and treatment was repeated twice more with time intervals. when...

Eriocheir sinensis, which is an important aquaculture species, belongs to the class Crustacea. To discuss the temperature tolerance of E. sinensis, the survival rates of juvenile crabs of E. sinensis were determined in this paper using a series of temperature settings (normal temperature, 25°C, 30°C, 32°C, 34°C, 35°C, 36°C, 38°C, 40 °C). The results indicated that except the normal temperature ...
