Parent Encouragement & Infant\u27s Visual Attention
Attention to objects appears to be linked to the development of early motor skills and experience with objects. Looking is an important aspect of object exploration, especially sustained looking to objects (Rochat, 1989)
Massive Necrotizing Pancreatitis in an Immunosuppressed Renal Transplant Recipient (Successful Therapy)
Severe pancreatitis may be associated with massive necrosis of the pancreas and/or retroperitoneal
adipose tissue. Toxicity results from the dead tissue and secondary infection. A 45 year old patient,
while fully immunosuppressed, developed this complication following cadaveric renal transplantation.
He survived continued immunosuppression, 16 operative debridements of the retroperitoneum, and
maintained a functioning renal transplant
Single-fiber reflectance spectroscopy of isotropic-scattering medium: An analytic perspective to the ratio-of-remission in steady-state measurements
Recent focused Monte Carlo and experimental studies on steady-state single-fiber reflectance spectroscopy (SfRS) from a biologically relevant scattering medium have revealed that, as the dimensionless reduced scattering of the medium increases, the SfRS intensity increases monotonically until reaching a plateau. The SfRS signal is semi-empirically decomposed to the product of three contributing factors, including a ratio-of-remission (RoR) term that refers to the ratio of photons remitting from the medium and crossing the fiber-medium interface over the total number of photons launched into the medium. The RoR is expressed with respect to the dimensionless reduced scattering parameter Ī¼'s dfib, where Ī¼'s is the reduced scattering coefficient of the medium and dfib is the diameter of the probing fiber. We develop in this work, under the assumption of an isotropic-scattering medium, a method of analytical treatment that will indicate the pattern of RoR as a function of the dimensionless reduced scattering of the medium. The RoR is derived in four cases, corresponding to in-medium (applied to interstitial probing of biological tissue) or surface-based (applied to contact-probing of biological tissue) SfRS measurements using straight-polished or angle-polished fiber. The analytically arrived surface-probing RoR corresponding to single-fiber probing using a 15Ā° angle-polished fiber over the range of Ī¼'s dfib = (10-2 103) agrees with previously reported similarly configured experimental measurement from a scattering medium that has a Henyey-Greenstein scattering phase function with an anisotropy factor of 0.8. In cases of a medium scattering lightanisotropically, we propose how the treatment may be furthered to account for the scattering anisotropy using the result of a study of light scattering close to the point-of-entry by Vitkin et al.Electrical & Computer Engineerin
ABA RPTE Conservation Easement Task Force Report: Recommendations Regarding Conservation Easements and Federal Tax Law
In October 2015, the American Bar Associationās Real Property, Trust and Estate Law (RPTE) section convened a Conservation Easement Task Force. The objective of the Task Force was to provide recommendations regarding federal tax law as it relates to conservation easements. This Report is the culmination of the Task Forceās work. Part I of the Report is an Executive Summary of the Task Forceās recommendations. Part II provides the background necessary to understand the Task Forceās recommendations. Part III briefly sets forth the Task Forceās comments on the Tax Cuts and Jobs Act of 2017 as it relates to charitable contributions in general and conservation easement donations in particular. In Part IV, the Task Force recommends that the Treasury publish safe harbor provisions that would be common to most conservation easements. Part V sets forth the Task Forceās recommendations regarding amendments and discretionary consents, the inconsistent use regulations, and furthering transparency in conservation easement administration. Part VI discusses issues surrounding valuation of conservation easements. Part VII contains a brief comment on syndicated conservation easement transactions. Part VIII is the Task Force response to certain proposals the Treasury Department made (most recently in 2016) to change conservation easement law.Appendix A sets forth the āperpetuityā requirements of Ā§ 170(h) and the Treasury Regulations.Appendix B offers specific language to facilitate the preparation of key safe harbor provisions
Concrete governmentality: shelters and the transformations of preparedness
This article analyses how shelters act as a form of concrete governmentality. Shelters, like other forms of preparedness, are political acts in the absence of a disaster. They are materializations and visualizations of risk calculations. Shelters as a type of concrete governmentality pose the question of how to build something that lasts and resists, and remains relevant both when the object that is being resisted keeps changing and when the very act of building intervenes so publically in the life of the restless surrounding population. Comparing shelters in India, Switzerland and the UK, we highlight three transformations of preparedness that shelters trigger. First we analyse how shelters compose preparedness by changing the relationship between the state and its citizens. Rather than simply limiting risk or introducing āsafetyā, the building of shelters poses questions about who needs protection and why and, as we will show, this can generate controversy. Second, we analyse how shelters decompose preparedness by falling out of use. Third, we focus on struggles to recompose preparedness: Changing ideas about disasters thus lead to shelters being suddenly out of place, or needing to adapt
PPARĪ± Deficiency in Inflammatory Cells Suppresses Tumor Growth
Inflammation in the tumor bed can either promote or inhibit tumor growth. Peroxisome proliferator-activated receptor (PPAR)Ī± is a central transcriptional suppressor of inflammation, and may therefore modulate tumor growth. Here we show that PPARĪ± deficiency in the host leads to overt inflammation that suppresses angiogenesis via excess production of the endogenous angiogenesis inhibitor thrombospondin-1 and prevents tumor growth. Bone marrow transplantation and granulocyte depletion show that PPARĪ± expressing granulocytes are necessary for tumor growth. Neutralization of thrombospondin-1 restores tumor growth in PPARĪ±-deficient mice. These findings suggest that the absence of PPARĪ± activity renders inflammatory infiltrates tumor suppressive and, thus, may provide a target for inhibiting tumor growth by modulating stromal processes, such as angiogenesis
Comprehensive Molecular Characterization of Papillary Renal-Cell Carcinoma
BACKGROUND Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. METHODS We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. RESULTS Type 1 and type 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into three individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2'antioxidant response element (ARE) pathway. A CpG island methylator phenotype (CIMP) was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase (FH). CONCLUSIONS Type 1 and type 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CIMP in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renalcell carcinoma consisted of at least three subtypes based on molecular and phenotypic features
