Early diagnosis along with new drugs targeted to cancer receptors and immunocheckpoints have improved breast cancer survival. However, full remission remains elusive for metastatic breast cancer due to dose-limiting toxicities of heavily used, highly potent drug combinations such as gemcitabine and paclitaxel. Therefore, novel strategies that lower the effective dose and improve safety margins could enhance the effect of these drug combinations. To this end, we developed and evaluated a novel drug combination of gemcitabine and paclitaxel (GT). Leveraging a simple and scalable drug-combination nanoparticle platform (DcNP), we successfully prepared an injectable GT combination in DcNP (GT DcNP). Compared to a Cremophor EL/ethanol assisted drug suspension in buffer (CrEL), GT DcNP exhibits about 56-fold and 8.6-fold increases in plasma drug exposure (area under the curve, AUC) and apparent half-life of gemcitabine respectively, and a 2.9-fold increase of AUC for paclitaxel. Using 4T1 as a syngeneic model for breast cancer metastasis, we found that a single GT (20/2 mg/kg) dose in DcNP nearly eliminated colonization in the lungs. This effect was not achievable by a CrEL drug combination at a 5-fold higher dose (i.e., 100/10 mg/kg GT). A dose-response study indicates that GT DcNP provided a therapeutic index of ~15.8. Collectively, these data suggest that GT DcNP could be effective against advancing metastatic breast cancer with a margin of safety. As the DcNP formulation is intentionally designed to be simple, scalable, and long-acting, it may be suitable for clinical development to find effective treatment against metastatic breast cancer.A Compton camera is a device for imaging a radio-source distribution without using a mechanical collimator. Ordered-subset expectation-maximization (OS-EM) is widely used to reconstruct Compton images. However, the OS-EM algorithm tends to over-concentrate and amplify noise in the reconstructed image. It is, thus, necessary to optimize the number of iterations to develop high-quality images, but this has not yet been achieved. In this paper, we apply a median filter to an OS-EM algorithm and introduce a median root prior expectation-maximization (MRP-EM) algorithm to overcome this problem. In MRP-EM, the median filter is used to update the image in each iteration. We evaluated the quality of images reconstructed by our proposed method and compared them with those reconstructed by conventional algorithms using mathematical phantoms. The spatial resolution was estimated using the images of two point sources. Reproducibility was evaluated on an ellipsoidal phantom by calculating the residual sum of squares, zero-mean normalized cross-correlation, and mutual information. In addition, we evaluated the semi-quantitative performance and uniformity on the ellipsoidal phantom. MRP-EM reduces the generated noise and is robust with respect to the number of iterations. An evaluation of the reconstructed image quality using some statistical indices shows that our proposed method delivers better results than conventional techniques.Conversion of vacuum fluctuations into real particles was first predicted by L. Parker considering an expanding universe, followed in S. Hawking's work on black hole radiation. Since their experimental observation is challenging, analogue systems have gained attention in the verification of this concept. Here we propose an experimental set-up consisting of two adjacent piezoelectric semiconducting layers, one of them carrying dynamic quantum dots (DQDs), and the other being p-doped with an attached gate on top, which introduces a space-dependent layer conductivity. The propagation of surface acoustic waves (SAWs) on the latter layer is governed by a wave equation with an effective metric. In the frame of the DQDs, this space- and time-dependent metric possesses a sonic horizon for SAWs and resembles that of a two dimensional non-rotating and uncharged black hole to some extent. The non-thermal steady state of the DQD spin indicates particle creation in form of piezophonons.BACKGROUND Intimate partner violence (IPV) is prevalent in high- as well as low-income contexts. It results in a substantial public health burden and significant negative socioeconomic and health outcomes throughout the life-course. However, limited knowledge exists about IPV during early adolescence. This period is critical during the transition to adulthood for at least two reasons it is when the majority of adolescents in low-income countries first encounter dating, sexuality and partnerships, often with older adolescents or adults, and it is also the period when lifelong patterns of violence and norms about acceptable IPV are formed. The current study is one of the first to measure IPV prevalence among young adolescents in a low-income setting, examine the potential etiology, and investigate relationships with gender ideology, poverty, mental health and childhood adversity. METHODS We surveyed 2,089 adolescents aged 10-16 in Malawi using standardized instruments. We estimated the prevalence of IPV, and us. IPV compounds other adversities experienced by adolescents in this low-income setting, and it is rarely alleviated through help from the health system or other formal support.  https://www.selleckchem.com/products/dansylcadaverine-monodansyl-cadaverine.html  These findings underscore the need to intervene early when interventions can still break destructive pathways and help foster healthier relationships. This focus on early adolescence is particularly critical in low-income countries given the early onset and rapid pace of the transition to adulthood, with sexual activity, dating and partnership thus being common already in young adolescence. Promising interventions would be those that reduce violence against or around children, as well as those that reduce the impacts of such trauma on mental health during adolescence.Adherence to antiretroviral therapy (ART) is essential to achieving an improved cluster of differentiation-4 (CD4) count, viral load, and quality of life while preventing drug resistance. Medication adherence among people living with Human Immunodeficiency Virus (HIV) is influenced by different factors. Several studies have identified adherence promoters and inhibitors that emanate from the internal and external environment. We conducted six (6) individual in-depth interviews and three (3) focus group discussions to explore adherence behaviour among patients diagnosed with HIV in a teaching hospital in Accra, Ghana. Participants were drawn from the intervention arm of a mobile phone adherence intervention program. They had been enrolled in the study for at least six (6) months before the interviews are conducted. Results revealed that participants adhered to treatment irrespective of prompts from significant others. Adherence promoters included perception of ART as part of daily routines, benefits of the ART, awareness of regimen, access to food, and transparency.
