Traditional underrepresented minority (URM) groups (African Americans, Hispanic Americans, Native Americans) remain underrepresented among physician-scientists. To address the dearth of URM physician-scientists, in 1993 the Weill Cornell/Rockefeller/Sloan Kettering Tri-Institutional MD-PhD Program developed a pipeline program, Gateways to the Laboratory (Gateways), which focuses on increasing the breadth and depth of the URM physician-scientist pipeline by offering an all-encompassing summer research training program which mirrors the life of a physician-scientist...

Helping breast cancer patients who desire a pregnancy after cancer treatment is a vital issue. Little is known about the complex context of the decision to become pregnant after breast cancer treatment. The purpose of this study was to understand the risk-benefit perception of choosing conception or contraception after treatment in Taiwan. We applied grounded theory to guide this exploratory qualitative study. Data were collected through in-depth interviews with 16 breast cancer patients. Pregnancy was addressed in the context of cancer as a potentially life-threatening diagnosis and its treatment...

Jessica Lopez, M Shahid Mukhtar
A tremendous asset to the analysis of protein-protein interactions is the yeast-2-hybrid (Y2H) method. The Y2H assay is a heterologous system that is expanding network biology knowledge via in vivo investigations of binary protein-protein interactions. Traditionally, the Y2H protocol entails the mating or co-transformation of yeast in solid agar media followed by visual analysis for diploid selection. Having played a key role in identifying protein-protein interactions for nearly three decades in a wide range of biological systems, the Y2H system assays the interaction between two proteins of interest which results in a reconstituted and/or activation of transcription factor allowing a reporter gene to be transcribed...

Helen D Ford, Ralph P Tatam
Duct-profiling in test samples up to 25 mm in diameter has been demonstrated using a passive, low-coherence probe head with a depth resolution of 7.8 μm, incorporating an optical-fibre-linked conical mirror addressed by a custom-built array of single-mode fibres. Zemax modelling, and experimental assessment of instrument performance, show that degradation of focus, resulting from astigmatism introduced by the conical mirror, is mitigated by the introduction of a novel lens element. This enables a good beam focus to be achieved at distances of tens of millimetres from the cone axis, not achievable when the cone is used alone...

OBJECTIVE: Kidney puncture during percutaneous nephrolithotomy (PCNL) is regarded as one of the most demanding aspects of the procedure and only a minority of urologists perform this step without assistance by a radiologist. Currently a wide variation of fluoroscopic guided techniques is available in clinical practice. In this work we describe the most common fluoroscopic guided access techniques in a step-by-step manner aiming to assist on the standardization of their technique and terminology...

The accurate definition and staging of chronic kidney disease (CKD) is one of the major achievements of modern nephrology. Intensive research is now being undertaken to unravel the risk factors and pathophysiologic underpinnings of this disease. In particular, the relationships between the kidney and other organs have been comprehensively investigated in experimental and clinical studies in the last two decades. Owing to technological and analytical limitations, these links have been studied with a reductionist approach focusing on two organs at a time, such as the heart and the kidney or the bone and the kidney...

BACKGROUND: Emergency medical services are important to the functioning of health systems, but these services tend to be neglected in low- and middle-income countries, such as India. In recent years, several models of pre-hospital emergency medical services have emerged in India. Research on these models holds important lessons for existing and future emergency medical service programs in low- and middle-income countries. Our objective was to provide a comprehensive description of the organizational structure and service delivery model of a public-private partnership in the southern Indian state of Karnataka, GVK Emergency Management and Research Institute, with a particular focus on its operations in Bengaluru...

#14
Che-Chou Shen, Hsiao-Chi Yang
Ultrasound array imaging systems rely on a presumed beamforming sound velocity to calculate the time compensation of each element for receive focusing. The mismatch between the tissue sound velocity and the beamforming sound velocity can degrade the focusing quality due to loss of phase coherence. Since the tissue sound velocity cannot be known in prior, an adaptive optimization of beamforming sound velocity is required to improve the image quality. Differential phase gradient of channel data is proposed to estimate the optimal sound velocity for beamforming...

BACKGROUND: A range of studies has demonstrated the efficacy of the psychoactive Amazonian brew ayahuasca in addressing substance addiction. These have revealed that physiological and psychological mechanisms are deeply enmeshed. This article focuses on how interactive ritual contexts support the healing effort. The study of psychedelic-assisted treatments for addiction has much to gain from ethnographic analyses of healing experiences within the particular ecologies of use and care, where these interventions are rendered efficacious...

We present an investigation of the impact of partial coherence on optical imaging systems with the focus on whole slide imaging (WSI) systems for digital pathology. The investigation is based on the analysis of the edge response of the optical system, which gives rise to an apparent optical transfer function (OTF) that can be linked to two elementary complex functions Q and U. The function Q is directly related to the transmission cross coefficient (TCC) and can be identified with the performance function first introduced by Kintner and Sillitto...

Gastric cancer (GC) is one of the most common malignancies worldwide. The expression of CD147 protein is associated with GC. However, the clinical role of CD147 in GC has not been investigated extensively. Hence, we focused on studying the association between the expression of CD147 and clinicopathological features of GC patients in this study. Firstly, sixteen publications (1752 cases and 391 controls) and one from our own original research (143 cases) were included in the meta-analysis to obtain a more precise estimation of the diagnostic value of CD147...

Non-invasive, quantitative methods to assess the properties of biological tissues are needed for many therapeutic and tissue engineering applications. Magnetic resonance elastography (MRE) has historically relied on external vibration to generate periodic shear waves. In order to focally assess a biomaterial or to monitor the response to ablative therapy, the interrogation of a specific region of interest by a focused beam is desirable and transient MRE (t-MRE) techniques have previously been developed to accomplish this goal...
