BACKGROUND: Gallbladder cancer (GBC) is an aggressive and highly lethal biliary tract malignancy, with extremely poor prognosis. In the present study, we analyzed the potential involvement of MYBL2, a member of the Myb transcription factor family, in the carcinogenesis of human GBC. METHODS: MYBL2 expression levels were measured in GBC and cholecystitis tissue specimens using quantitative real-time PCR (qRT-PCR) and immunohistochemical (IHC) assays. The effects of MYBL2 on cell proliferation and DNA synthesis were evaluated using Cell Counting Kit-8 assay (CCK-8), colony formation, and 5-ethynyl-2'-deoxyuridine (EdU) retention assay, flow cytometry analysis, western blot, and a xenograft model of GBC cells in nude mice...

INTRODUCTION: Paragangliomas are neuroendocrine tumors arising from chromaffin cells located in sympathetic paraganglia. Mediastinal paragangliomas are extremely rare and can be classified as functional or non-functional according to their ability for secreting catecholamines. Patients can be asymptomatic and the diagnosis is usually incidental. Complete surgical resection remains the standard of care for paragangliomas. PRESENTATION OF CASE: We present a 44-year-old woman with a functional mediastinal paraganglioma incidentally found during the perioperative imaging workup for a diagnosed breast carcinoma...

REVIEW
Onur Güntürkün, Sebastian Ocklenburg
The brains of humans and other animals are asymmetrically organized, but we still know little about the ontogenetic and neural fundaments of lateralizations. Here, we review the current state of understanding about the role of genetic and non-genetic factors for the development of neural and behavioral asymmetries in vertebrates. At the genetic level, the Nodal signaling cascade is of central importance, but several other genetic pathways have been discovered to also shape the lateralized embryonic brain. Studies in humans identified several relevant genes with mostly small effect sizes but also highlight the extreme importance of non-genetic factors for asymmetry development...

HPV204 is the only newly identified Mupapillomavirus (Mu-PV) type in more than a decade. To comprehensively characterize HPV204, we performed a detailed molecular analysis of the viral genome and evaluated its clinical relevance in comparison to the other Mu-PVs, HPV1 and HPV63. The 7,227-bp long genome of HPV204 exhibits typical genomic organization of Mu-PVs with eight open reading frames (ORFs) (E6, E7, E1, E2, E8, E4, L2, and L1). We developed three type-specific quantitative real-time PCRs and used them to test a representative collection (n = 1,006) of various HPV-associated benign and malignant neoplasms, as well as samples of clinically normal cutaneous, mucosal, and mucocutaneous origins...

Wounds causing extensive injury loss of muscle, also known as volumetric muscle loss (VML), are frequently associated with high-energy civilian trauma and combat-related extremity injuries. Currently, no effective clinical therapy is available for promoting de novo muscle tissue regeneration to restore muscle function following VML. Recent studies have shown evidence that osteoactivin (OA), a transmembrane glycoprotein, has the ability to prevent skeletal muscle atrophy in response to denervation. Therefore the objective of this study is to investigate the potential regenerative effect of OA embedded and delivered via a cross-linked gelatin hydrogel within a volumetric tibialis anterior muscle defect in a rat model...

BACKGROUND: Access to highly specialized health care services and support to meet the patient's specific needs is critical for health outcome, especially during age-related transitions within the health care system such as with adolescents entering adult medicine. Being affected by an orphan disease complicates the situation in several important respects. Long distances to dedicated institutions and scarcity of knowledge, even among medical doctors, may present major obstacles for proper access to health care services and health chances...

PURPOSE OF REVIEW: The aim of this study was to summarize developments in the adjuvant/neoadjuvant chemotherapy of high-risk adult-type soft tissue sarcomas (STS). RECENT FINDINGS: The role of adjuvant/neaodjuvant chemotherapy in these patients is controversial, with a meta-analysis suggesting a 10% survival benefit. Recently, a randomized controlled trial in high-risk STS of extremities and trunk wall showed a 20% improvement in progression-free and overall survival after three preoperative cycles of epirubicin along with ifosfamide compared with a histology-tailored chemotherapy...

In the last decade, Romanian hospitals have been facing a decline in autopsy rates. This has had a negative impact on medical education and the training of young doctors. Quite a number of caregivers strongly oppose the carrying out of autopsies on their deceased loved ones who have died in hospital. Hence, this study was designed to evaluate how autopsies are perceived by an average person and whether improved knowledge about autopsies would help reduce people's reluctance toward them. The study involved 216 willing participants who had either never had a loved one die in hospital or had never had the power to make a decision about their dead loved ones' body...

The Mascarene grass frog Ptychadena cf. mascareniensis is a species of frog with a vast area of distribution in Africa. A total of 300 frog specimens were collected from different localities at El-Giza province, Egypt; then dissected and examined for the presence of parasitic infection. Only eighty six (28.66%) specimens were found to be naturally infected with nematode parasite. Seasonally, the prevalence of infection was reached its maximum value of 74.66% during summer and minimum values of 26.66% (20/75), 13...

Many synthetic DNA minor groove binders exhibit a strong increase in fluorescence when bound to DNA. The pharmaceutical-relevant berenil (diminazene aceturate) is an exception with an extremely low fluorescence quantum yield (on the order of 10(-4)). We investigate the ultrafast excited-state dynamics of this triazene by femtosecond time-resolved fluorescence experiments in water, ethylene glycol, and buffer and bound to the enzyme β-trypsin, the minor groove of AT-rich DNA, and G-quadruplex DNA. Ab initio calculations provide additional mechanistic insight...

INTRODUCTION: Social-structural inequities impede access to, and retention in, HIV care among structurally vulnerable people living with HIV (PLHIV) who use drugs. The resulting disparities in HIV-related outcomes among PLHIV who use drugs pose barriers to the optimization of HIV treatment as prevention (TasP) initiatives. We undertook this study to examine engagement with, and impacts of, an integrated HIV care services model tailored to the needs of PLHIV who use drugs in Vancouver, Canada - a setting with a community-wide TasP initiative...

A series of nitrogen-rich "green" Energetic Materials (EMs), some with improved sensitivity, thermostability, and very low toxicity, were synthesized on the basis of 3,5-diamino-1,2,4-triazole (DAT) and 1,2,4,5-tetrazine building blocks. Since DAT contains several nucleophilic reactive sites, obtaining selective reactivity and specific isomeric products with 1,2,4,5-tetrazine precursors is a challenging task. We developed reaction conditions under which specific isomers could be prepared. On evaluating these compounds for their energetic properties, we found that N(5),N(5)'-(1,2,4,5-tetrazine-3,6-diyl)-bis(1H-1,2,4-triazole-3,5-diamine) 1 has very high thermostability (onset of decomposition temperature at 357 °C) and it is insensitive to impact (Im > 98 J), friction (>360 N) and electrostatic discharge (2512 mJ)...

Presently, we aim to elucidate osteogenic effects of two silica-based xerogels with different degrees of bioactivity on human bone-derived mesenchymal stromal cells. By means of scanning electron microscopy and quantitative PCR enhanced osteogenic effects and the formation of an extracellular matrix could be ascribed to the sample with lower bioactivity. Given the high levels of bioactivity, the cells revealed remarkable sensitivity to extremely low calcium levels of the media. Therefore, additional experiments were performed to elucidate cell behavior under calcium deficient conditions...

Aging is associated with progressive visceral white adipose tissue (WAT) expansion both in human and mouse. Importantly, WAT enlargement is initiated early in life, suggesting that molecular mechanisms underlying age-dependent obesity are activated at early stages of lifetime. Our recent study found that age-dependent obesity was associated with a specific decline in mitochondrial complex IV activity, which leads to reduced fatty acid oxidation and subsequent adipocyte hypertrophy. At the molecular level, global mitochondrial complex IV inhibition was driven by hypoxia-inducible factor-1α (HIF1α)-mediated repression of some of its key subunits, including cytochrome c oxidase 5b (Cox5b)...
