#1
Nikhil R Jana, Chumki Dalal
Although trans-activating transcription (TAT)-peptide functionalized nanoparticle/polymer/liposome is widely used for cellular transfection applications, the multivalency (number of attached peptide per particle) effect on cell uptake mechanism and subcellular targeting performance is largely unexplored. Here we show that multivalency of nanoparticle controls the cellular interaction, cellular entry/exit mechanism and subcellular targeting performance. We have synthesized TAT peptide functionalized quantum dot (QD) of 30-35 nm hydrodynamic diameter with varied multivalency from 10 to 75 (e...

Variable temperature magic angle spinning (MAS) NMR measurements are reported on (1)H and (31)P nuclei in KH2PO4 (KDP) in the vicinity of its paraelectric-ferroelectric phase transition temperature, T c, of 123 K, to examine the transition mechanism, in particular if this is a model order-disorder type or whether it also involves a displacive component. It has been well established that the temperature variation of the isotropic chemical shift, δ iso, in NMR measurements of the nuclei directly involved in the transition should remain constant or change smoothly through T c for an order-disorder type transition but it should show an anomalous change for a displacive one...

BACKGROUND: Pseudoxanthoma elasticum-like papillary dermal elastolysis (PXE-PDE), a rare acquired elastolytic disorder, occurs in postmenopausal, elderly women and is characterized by soft, white-yellow papules that localize on the neck and supraclavicular regions and often coalesce into cobblestone plaques. It has no systemic involvement and is histologically distinct from the clinically similar inherited pseudoxanthoma elasticum. CASE SUMMARY: A 64-year-old Caucasian woman presented with a 2-year history of multiple, asymptomatic soft yellow 1- to 2-mm papules on her neck, which were increasing in number...

Photo-reorganization of 3-alkoxy-6-chloro-2-(benzo[b]thiophen-2-yl)-4H-chromen-4-ones in methanol with Pyrex filtered UV-light from a medium pressure 125 W Hg-vapor lamp led to the formation of angular pentacyclic compounds (dihydro and aromatic products) along with some rearranged chromenones where the product(s) distribution depended upon the structure of 3-alkoxy groups (methoxy, ethoxy, allyloxy and benzyloxy). The phenyl moiety in the 3-benzyloxy group had a profound effect on the dihydro product(s) formation as the latter was in high yield when the alkoxy group was benzyloxy followed by allyloxy, ethoxy and methoxy groups...

BACKGROUND: Postoperative formation of adhesions increases risk of complications during cardiac reoperations. We previously demonstrated that swine supplemented with vodka had a significant reduction in adhesions at sternotomy after previous thoracotomy. This follow-up study was conducted to determine reproducibility and the mechanism for adhesion reduction in swine supplemented with ethanol. METHODS: An ameroid constrictor was placed in the left circumflex in 14 male Yorkshire swine to induce chronic myocardial ischemia through left minithoracotomy...

REVIEW
Pratik K Dalal, Anand Prasad
Critical limb ischemia (CLI) remains a significant cause of morbidity and mortality in patients with peripheral arterial disease. Optimal treatment strategies for CLI remain controversial. The only randomized trial comparing surgical with endovascular revascularization suggests no significant difference in limb salvage between open surgical bypass and angioplasty. Although novel endovascular strategies are now available, their efficacies remain largely untested in a randomized fashion. This review provides an overview of the data surrounding contemporary outcomes of endovascular therapy with an emphasis on current knowledge gaps...

BACKGROUND: Ulcerative colitis (UC) only involves the colonic mucosa. Yet, nearly 50% of patients with UC who undergo total proctocolectomy with ileal pouch anal anastomosis develop UC-like inflammation of the ileal pouch (pouchitis). By contrast, patients with familial adenomatous polyposis (FAP) with ileal pouch anal anastomosis develop pouchitis far less frequently. We hypothesized that pathogenic events associated with the development of UC are recapitulated by colonic-metaplastic transcriptomic reprogramming of the UC pouch...

Background: Myeloid sarcoma (MS) or granulocytic sarcoma is a rare tumor consisting of myeloid blasts with or without maturation occurring at anatomic sites other than the bone marrow. MS can involve any organ system but shows a predilection for skin, bone, and soft tissues of head and neck region. Case report: We report four cases of MS occurring at unusual sites, out of which three were de novo and one was associated with acute myeloid leukemia (AML). Conclusion: Although MS is associated with AML, it can rarely present without any existent hematologic disease...

Importance: Medical errors and adverse events (AEs) are common among hospitalized children. While clinician reports are the foundation of operational hospital safety surveillance and a key component of multifaceted research surveillance, patient and family reports are not routinely gathered. We hypothesized that a novel family-reporting mechanism would improve incident detection. Objective: To compare error and AE rates (1) gathered systematically with vs without family reporting, (2) reported by families vs clinicians, and (3) reported by families vs hospital incident reports...

BACKGROUND: Hepatic encephalopathy is a disorder of brain function as a result of liver failure or portosystemic shunt or both. Both hepatic encephalopathy (clinically overt) and minimal hepatic encephalopathy (not clinically overt) significantly impair patient's quality of life and daily functioning, and represent a significant burden on healthcare resources. Probiotics are live micro-organisms, which when administered in adequate amounts, may confer a health benefit on the host. OBJECTIVES: To determine the beneficial and harmful effects of probiotics in any dosage, compared with placebo or no intervention, or with any other treatment for people with any grade of acute or chronic hepatic encephalopathy...

Primary progress has been made in the last 2 years, particularly in finding novel disease-causing genes for a number of autoinflammatory diseases and primary immunodeficiencies. Whole-exome sequencing has dramatically increased the pace at which causative genes are being discovered. CECR1 (Cat eye syndrome chromosome region, candidate 1) gene encodes adenosine deaminase 2 (ADA2) protein. Patients who carry CECR1 mutation(s) suffer from deficiency of ADA2 (DADA2). Here, we describe a patient with pure red cell aplasia discovered to have DADA2...

Cefuroxime axetil (CFA), an ester prodrug of cefuroxime exists as a pair of diastereoemers, namely isomer A and isomer B. To enable phase diagram construction, crystallization of the diastereomers of CFA from the commercially available amorphous drug substance was carried out. Isomer A was separated with a purity approaching 100% whereas the maximum purity of isomer B was 85% as confirmed by solution state proton NMR spectroscopy. The crystalline forms of isomer A and isomer B were confirmed as forms AI and BI, respectively, based on differential scanning calorimetry (DSC) analysis and powder X-ray diffraction...
