Abstract
Breast cancer is the leading cause of cancer-related deaths in women worldwide, with the basal-like or triple-negative breast cancer (TNBC) subtype being particularly aggressive and challenging to treat. Understanding the molecular mechanisms driving the development and progression of TNBC is essential. We previously showed that WW domain-containing oxidoreductase (WWOX) is commonly inactivated in TNBC and is implicated in the DNA damage response (DDR) through ATM and ATR activation. In this study, we investigated the interplay between WWOX and BRCA1, both frequently inactivated in TNBC, on mammary tumor development and on DNA double-strand break (DSB) repair choice. We generated and characterized a transgenic mouse model (K14-Cre;Brca1fl/fl;Wwoxfl/fl) and observed that mice lacking both WWOX and BRCA1 developed basal-like mammary tumors and exhibited a decrease in 53BP1 foci and an increase in RAD51 foci, suggesting impaired DSB repair. We examined human TNBC cell lines harboring wild-type and mutant BRCA1 and found that WWOX expression promoted NHEJ repair in cells with wild-type BRCA1. Our findings suggest that WWOX and BRCA1 play an important role in DSB repair pathway choice in mammary epithelial cells, underscoring their functional interaction and significance in breast carcinogenesis.

Abstract
Though, suicide is a preventable public health problem but prediction is almost impossible. Nevertheless, past suicidal behaviors are important risk factors which should be considered to prevent deaths by suicides. We aimed to explore the suicidal behaviors among currently employed nurses working in a referral hospital of Bangladesh. This cross-sectional study was conducted from August to September 2018 among 203 currently working nurses of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. Data were collected by face to face interview with pre-tested semi-structured questionnaire and analyzed by Statistical Package for the Social Sciences software version 20.0. Among the 203 respondents; 175 were female and 28 were male, whose mean age was 28.96±4.08 years, ranging from 22-40 year. About 71% were married, 75% had educational attainment of diploma in nursing, 2% had family history of mental illness and suicide, and another one percent had family history of suicidal attempts. Prevalence of life time suicidal ideation was found as 10%, one-year prevalence rate 4%, one month 2% and within last two days it was found as 1.5%. Mean age of onset of suicidal ideation of the respondents was 23.81±4.9 year ranging from 17-35 year. Late adolescence was found as the entry time of the suicidal thoughts among this specific group. About one in ten nurses had suicidal ideation in their life time. Further larger scale and longitudinal studies are warranted to find out more precise information.

Abstract
Electrochemotherapy is now in development for treatment of deep-seated tumors, like in bones and internal organs, such as liver. The technology is available with a newly developed electric pulse generator and long needle electrodes; however the procedures for the treatment are not standardized yet. In order to describe the treatment procedure, including treatment planning, within the ongoing clinical study, a case of successful treatment of a solitary metastasis in the liver of colorectal cancer is presented. The procedure was performed intraoperatively by inserting long needle electrodes, two in the center of the tumor and four around the tumor into the normal tissue. The insertion of electrodes proved to be feasible and was done according to the treatment plan, prepared by numerical modeling. After intravenous bolus injection of bleomycin the tumor was exposed to electric pulses. The delivery of the electric pulses did not interfere with functioning of the heart, since the pulses were synchronized with electrocardiogram in order to be delivered outside the vulnerable period of the ventricles. Also the post treatment period was uneventful without side effects. Re-operation of the treated metastasis demonstrated feasibility of the reoperation, without secondary effects of electrochemotherapy on normal tissue. Good antitumor effectiveness with complete tumor destruction was confirmed with histological analysis. The patient is disease-free 16 months after the procedure. In conclusion, treatment procedure for electrochemotherapy proved to be a feasible technological approach for treatment of liver metastasis. Due to the absence of the side effects and the first complete destruction of the treated tumor, treatment procedure for electrochemotherapy seems to be a safe method for treatment of liver metastases with good treatment effectiveness even in difficult-to-reach locations.

Abstract
The combined treatment of tumours in which delivery of a chemotherapeutic agent is followed by high voltage electroporation pulses has been termed electrochemotherapy. The electrochemotherapy of tumours located relatively close to the heart muscle can lead to fibrillation of the heart, especially if electroporation pulses are delivered in the vulnerable period of the heart or in coincidence with heart arrhythmias. We built an electroporation pulse delivery algorithm that enables safer use of electrochemotherapy. The algorithm is designed to deliver pulses outside the vulnerable period and to prevent pulses from being generated in the presence of heart arrhythmias. We evaluated the algorithm's performance using records of the Long-Term ST Database, thus simulating real-world conditions. The results of the evaluation, a sensitivity of 91.751%, a positive predictivity of 100.000% and a delivery error rate of 8.268% for electroporation pulse delivery (medians), suggest that the algorithm is accurate and appropriate for application in electrochemotherapy of tumours regardless of tumour location.

Abstract
The effect of the external cations Na+ and Ca2+ on polymorphonuclear chemiluminescence was investigated. Both Ca2+ in the range of 0.2-2 mM and Na+ in the range of 114-143 mM showed a dose dependent increase in polymorphonuclear chemiluminescence, irrespective of the concurrent increase in osmolality. The Na+/H+ antiport inhibitor Amiloride decreased the response significantly. These effects were observed using buffers commonly used for chemiluminescence studies and indicate the importance of defining the Ca2+ and Na+ composition of the buffers used in chemiluminescence assays.

Abstract
Cervical smears from 1,784 women who attended the family planning clinics of the Institute for Research in Reproduction were examined for the presence of Actinomyces-like organisms. Among 815 intrauterine contraceptive device (IUD) users, the repeat smears from 57 women were positive for Actinomyces-like organisms, giving a prevalence rate of 6.99%. Immunofluorescent staining using specific antisera confirmed the presence of A. israelii in all 57 women. Forty IUD users whose smears were positive for Actinomyces-like organisms underwent bacteriologic culture studies; A. israelii was isolated in 23 of these cases. The clinical findings at the time of smear collection in the 57 IUD users were within normal limits. The initial cervical smears of all IUD users and both the initial and repeat smears of all nonusers were negative for Actinomyces-like organisms. The data indicate that prolonged use (greater than 2 years) of an inert or copper intrauterine device promotes the overgrowth of Actinomyces in the vagina and that this can be detected by routine cervical cytology.
