Oto-palato-digital syndrome type 1 (OPD1) is an X-linked recessive disorder comprising characteristic facial appearances and skeletal alterations. The authors report OPD1 in a mother and her 2 sons who had multiple common congenital anomalies. Both of the brothers were born with mild hearing impairment, frontal bossing with prominent supraorbital ridges, downslanting palpebral fissures, dental malocclusion, and palatal clefts. They underwent a series of aesthetic surgeries for their facial malformations with good cosmetic results...

The Patient Protection and Affordable Care Act (ACA) included multiple provisions expected to increase cancer screening and subsequently early diagnosis of cancer. Key provisions included new coverage options for low-income adults and young adults, as well as elimination of cost sharing for recommended preventive services across most health insurance plans. This article reviews relevant quantitative studies published since the ACA's passage to assess whether the goal of increasing access to preventive services has been met...

Therapies based on activation of multiple Toll-like receptors (TLRs) may offer superior therapeutic profiles than that of single TLR activation. To discover new small molecules that could activate multiple TLRs, we performed a cell-based high-throughput screening of a small-molecule library based on TLR3-mediated NF-κB activation. Subsequent structural optimization and counter screening of other TLRs produced the first small molecule (CU-CPT24e) capable of simultaneously activating TLRs 3, 8, and 9. Biochemical studies demonstrated that CU-CPT24e could induce a strong immune response via the production of various cytokines in human monocytic THP-1 cells...

Importance: Depression in older adults is a common psychiatric disorder affecting their health-related quality of life. Major depression occurs in 2% of adults aged 55 years or older, and its prevalence rises with increasing age. In addition, 10% to 15% of older adults have clinically significant depressive symptoms, even in the absence of major depression. Observations: Depression presents with the same symptoms in older adults as it does in younger populations...

AIMS/HYPOTHESIS: Pancreatic beta-like cells generated from human induced pluripotent stem cells (hiPSCs) or human embryonic stem cells (hESCs) offer an appealing donor tissue source. However, differentiation protocols that mainly use growth factors are costly. Therefore, in this study, we aimed to establish efficient differentiation protocols to change hiPSCs/hESCs to insulin (INS)(+) cells using novel small-molecule inducers. METHODS: We screened small molecules that increased the induction rate of INS(+) cells from hESC-derived pancreatic and duodenal homeobox 1 (PDX1)(+) pancreatic progenitor cells...

Gene silencing mediated by dsRNA (RNAi) can persist for multiple generations in Caenorhabditis elegans (termed RNAi inheritance). Here we describe the results of a forward genetic screen in C. elegans that has identified six factors required for RNAi inheritance: GLH-1/VASA, PUP-1/CDE-1, MORC-1, SET-32, and two novel nematode specific factors that we term here (heritable RNAi defective) HRDE-2 and HRDE-4. The new RNAi inheritance factors exhibit mortal germline (Mrt) phenotypes, which we show is likely caused by epigenetic deregulation in germ cells...

Antigen-activated lymphocytes undergo extraordinarily rapid cell division in the course of immune responses. We hypothesized that this unique aspect of lymphocyte biology leads to unusual genomic stress in recently antigen-activated lymphocytes and that targeted manipulation of DNA damage-response (DDR) signaling pathways would allow for selective therapeutic targeting of pathological T cells in disease contexts. Consistent with these hypotheses, we found that activated mouse and human T cells display a pronounced DDR in vitro and in vivo...

Efflux pumps are one of the major determinants of multiple drug resistance. In this study, AbeM, a multidrug efflux pump in Acinetobacter baumannii, was cloned into a multicopy plasmid (pUC18) and was transformed into an efflux-deficient mutant of Escherichia coli (KAM32). The elevated resistance profile of the recombinant E. coli for ciprofloxacin was utilised to screen a small-molecule library of 8000 molecules to identify IITR08027, a small molecule that is not inhibitory on its own but that could potentiate the activity of ciprofloxacin...

S-adenosylhomocysteine hydrolase (AHCY) catalyzes the reversible hydrolysis of S-adenosylhomocysteine (SAH) to adenosine and L-homocysteine. This enzyme is frequently overexpressed in many tumor types and is considered to be a validated anti-tumor target. In order to enable the development of small molecule AHCY inhibitors as targeted cancer therapeutics we developed an assay based on a RapidFire high-throughput mass spectrometry detection system, which allows the direct measurement of AHCY enzymatic activity...

Metabolic engineering requires functional genetic tools for easy and quick generation of multiple pathway variants. A genetic engineering toolbox for A. niger is presented, which facilitates the generation of strains carrying heterologous expression cassettes at a defined genetic locus. The system is compatible with Golden Gate cloning, which facilitates the DNA construction process and provides high design flexibility. The integration process is mediated by a CRISPR/Cas9 strategy involving the cutting of both the genetic integration locus (pyrG) as well as the integrating plasmid...

Diffusion magnetic resonance imaging (dMRI) is a powerful tool in clinical applications, in particular, in oncology screening. dMRI demonstrated its benefit and efficiency in the localisation and detection of different types of human brain tumours. Clinical dMRI data suffer from multiple artefacts such as motion and eddy-current distortions, contamination by noise, outliers etc. In order to increase the image quality of the derived diffusion scalar metrics and the accuracy of the subsequent data analysis, various pre-processing approaches are actively developed and used...

Organ-on-a-chip has emerged as a powerful platform with widespread applications in biomedical engineering, such as pathology studies and drug screening. However, the fabrication of organ-on-a-chip is still a challenging task due to its complexity. For an integrated organ-on-a-chip, it may contain four key elements, i.e., a microfluidic chip, live cells/microtissues that are cultured in this chip, components for stimulus loading to mature the microtissues, and sensors for results readout. Recently, bioprinting has been used for fabricating organ-on-a-chip as it enables the printing of multiple materials, including biocompatible materials and even live cells in a programmable manner with a high spatial resolution...

In the general population, females experience depression at significantly higher rates than males. Individuals with traumatic brain injury (TBI) are at substantially greater risk for depression compared to the overall population. Treatment of, and recovery from, TBI can be hindered by depression; comorbid TBI and depression can lead to adverse outcomes and negatively affect multiple aspects of individuals' lives. Gender differences in depression following TBI are not well understood, and relevant empirical findings have been mixed...
