Bin Jia, Lei Xia, Fang Cao
Colorectal cancer (CRC) develops from the colon or rectum and is the fourth highest inducer of cancer mortality. In the present study, cancer tissues and normal tissues were extracted from patients with CRC who were treated in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine (Jinan, China). Reverse transcription-quantitative polymerase chain reaction demonstrated that the expression level of miR-766-5p was significantly higher (P<0.01) in cancer tissue than that in normal tissue...

Youth living with HIV (YLH) have significant problems with attending their medical appointments. Poor attendance, consequently, predicts viral non-suppression and other negative health outcomes. To identity targets of intervention, this cross-sectional study examined correlates of past-year missed clinic visits among YLH (N = 2125) attending HIV clinics in the United States and Puerto Rico. Thirty-six percent of YLH missed two or more visits in the past year. Several factors were associated with missed visits in our regression model...

In many emergency departments (EDs) around the country, providers care for patients experiencing homelessness on every single shift. Despite its proven impact on health, housing status is not a routine part of the history taken by most emergency providers, and in many cases providers are unaware that they are caring for someone who has no stable home. Patients experiencing homelessness have unique needs spanning acute and chronic illness, injury, behavioral health diagnoses, and material deprivation. This article is protected by copyright...

BACKGROUND: Human immunodeficiency virus (HIV) infection is associated with chronic immune activation, and concurrent sexually transmitted infections (STIs) may increase immune activation. OBJECTIVES: Because HIV-infected youth are at high risk of STIs and little is known about the impact of STIs on immune activation in HIV-infected youth, we conducted an exploratory study examining the association between STIs and systemic inflammation and immune activation among HIV-infected adolescents...

Jean-Baptiste Coty, Christine Vauthier
The nanotechnology revolution offers many expectations for the improvement of medicine treatments. At present, nanomedicine (NM) development is hampered by methodological barriers for a better characterization and a wider understanding of their in vivo behavior. While regulatory agencies setup guidelines to support NM translation from bench to bedside, the gap is still hardly overcome by main nanomedicines. One lever for filling this gap is a better characterization, thus increasing the global knowledge about the NM itself but also validate the confidence in terms of batch to batch reproducibility of such complex nano-objects...

The major goal of cancer chemotherapy is to maximize the therapeutic efficacy of anticancer drugs, while minimizing their associated side effects. Celastrol (CST), which is extracted from the traditional Chinese medicinal plant Tripterygium wilfordii, has been reported to exhibit significant anticancer effects in various in vitro and in vivo cancer models. Nanoparticulate drug delivery systems could be employed to preserve and enhance the pharmacological effects of CST in cancer cells. Among these, mesoporous silica nanoparticles (MSNs) are one of the most promising drug delivery systems...

In this article, we model the behavior of a pharmaceutical firm that has marketing authorization for a new therapy believed to be a candidate for personalized use in a subset of patients, but that lacks information as to why a response is seen only in some patients. We characterize the optimal outcome-based reimbursement policy a health authority should follow to encourage the pharmaceutical firm to undertake research and development activities to generate the information needed to effectively stratify patients...

BACKGROUND: Screening, brief intervention, and referral to treatment (SBIRT) is a promising public health approach for problematic substance use. A core component of SBIRT is the use of formal screening tools to categorize a patient's likely level of risk in order to provide an appropriately-matched service. Training in formal screening is included in many SBIRT training programs, but infrequently is emphasized. OBJECTIVES: To assess pre-training levels of SBIRT-related clinical behaviors, including screening, this study examined a secondary dataset collected from internal medicine residents and graduate nurse practitioner students...

Blood feeding is an essential and signature activity of the medicinal leech species, Hirudo verbana Despite keen interest in understanding the neuronal substrates of this behavior, a major component of the nervous system associated with feeding has remained overlooked. In this study, for the first time, we report on the presence and characteristics of five stomatogastic ganglia (STGs) comprising the visceral stomatogastric nervous system (STN) of the leech. Although Hanke (1948) provided a brief report that a ring of three ganglia (not five) was associated with the cephalic ganglia, this information was never integrated into subsequent neurobiological studies of feeding...

Human embryonic stem cells (hESCs) have the potential to form any cell type in the body, making them attractive cell sources in drug screening, regenerative medicine, disease and developmental processes modeling. However, not all hESC lines have the equal potency to generate desired cell types in vitro. Significant variations have been observed for the differentiation efficiency of various human ESC lines. The precise underpinning molecular mechanisms are still unclear. In this work, we compared transcriptome variations of four hESC lines H7, HUES1, HUES8 and HUES9...

Naringin is a flavanone that widely presents on daily diet and traditional medicinal materials. The ratios of naringin C-2 diastereomers are found different in reported samples, thus suspiciously leading to various functions. In this study, we measured the interconversion of C-2 diastereomers intensively with ultimate high-performance liquid chromatography and circular dichroism spectra. We examined the diastereomeric naringins in fresh citrus fruit, Huajuhong decoction pieces, and naringin tablet; evaluated the impact of tablet production procedures in factory; and monitored the rapid racemization in incubation...

Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The Adrenal Incidentaloma (AI) is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1...

Zic family proteins have been investigated in various biomedical studies. Here we summarize the contact points between Zic proteins and recent medical research. The topics cover a wide range, reflecting the pleiotropic roles of these proteins in early embryogenesis and organogenesis. Zic1, Zic2, and Zic3 proteins play important roles in the development of axial and limb bones, and of muscles, among the derivatives of the notochord and somites. Zic1 is involved in bone's response to mechanical stress, and it also serves as a marker specific for brown adipocytes...

A standardized medication plan (MP) was recently enacted into German law (§ 31a SGB V). The purpose of our study was to assess if patients with chronic diseases requiring polymedication understand the standardized MP and can transfer the given information into practice. 100 patients who took at least five medicines regularly were prospectively included in a cross-sectional study: 50 patients with the primary diagnosis chronic heart failure (CHF), and 50 with diabetes mellitus type 2 (DMT2). We performed a structured test-scenario studying the handling of a provided MP then evaluated the execution of the information on the MP by filling pill boxes and requested patients' opinion...

Transferrins (TFs) consist of a large group of glycoproteins, whose function is to transport iron across the cell membrane. Apart from iron, serum transferrin can also bind several other metal ions and hence can offer a potential route for the delivery of these metal ions into the cellular fluids. In the present study the interaction behavior of nine noble metal ions, Ag+, Au+, Au3+, Os3+, Pd2+, Pt4+, Rh3+, Ru3+ and Ir3+ with transferrin was investigated by affinity capillary electrophoresis (ACE) using the dynamic mobility shift mode...

Cognitive behavioral therapy (CBT) is an effective treatment for many with obsessive-compulsive disorder (OCD). However, response varies considerably among individuals. Attaining a means to predict an individual's potential response would permit clinicians to more prudently allocate resources for this often stressful and time-consuming treatment. We collected resting-state functional magnetic resonance imaging from adults with OCD before and after 4 weeks of intensive daily CBT. We leveraged machine learning with cross-validation to assess the power of functional connectivity (FC) patterns to predict individual posttreatment OCD symptom severity...

In virtually every field of medicine, non-inferiority trials and meta-analyses with non-inferiority conclusions are increasingly common. This non-inferiority approach has been frequently used by a group of authors favoring psychodynamic therapies (PDTs), concluding that PDTs are just as effective as cognitive-behavioral therapies (CBT). We focus on these examples to exemplify some problems associated with non-inferiority tests of psychological treatments, although the problems also apply to psychopharmacotherapy research, CBT research, and others...

Photo-crosslinkable poly(trimethylene carbonate) (PTMC) macromers were used to fabricate microstructured surfaces. Microstructured PTMC surfaces were obtained by hot embossing the macromer against structured silicon masters, subsequent photo-crosslinking then results in network formation. The microstructures of the master could be precisely replicated, shrinkage being limited. Microstructured PTMC was investigated for use in two different applications: as stamping material to transfer a model protein to another surface and as structured substrate for cell culture...
