Effects of Hydrophobic Tail Length Variation on Surfactant-Mediated Protein Stabilization.

Mol Pharm 2020 11 15;17(11):4302-4311. Epub 2020 Oct 15.

Department of Chemistry, University of Minnesota, Minneapolis, Minnesota 55455-0431, United States.

Recently, protein therapeutics have gained significant attention as a result of their enhanced selectivity and diminished side effects compared to traditional small-molecule drugs. Despite their advantages, protein formulations typically suffer from stability issues because of aggregation and denaturation during production and storage, often resulting in detrimental immune responses. Surfactants can be used to stabilize and protect proteins in solution by preventing protein adsorption onto interfaces or by forming protective structures in solution. Read More

Intravoxel incoherent motion (IVIM) 3 T MRI for orbital lesion characterization.

Eur Radiol 2021 Jan 1;31(1):14-23. Epub 2020 Aug 1.

Université de Paris, PARCC, INSERM, F-75015, Paris, France.

Development of Low Frequency (20-100 kHz) Clinically Viable Ultrasound Applicator for Chronic Wound Treatment.

IEEE Trans Ultrason Ferroelectr Freq Control 2019 03 14;66(3):572-580. Epub 2018 May 14.

This paper details the systematic approach used to develop a viable clinical prototype of a therapeutic ultrasound applicator and discusses the rationale and deliberations that led to the design strategy. The applicator was specifically devised to treat chronic wounds and-to the best of the author's knowledge-is the first truly wearable device with a proven record of reducing healing time, directly translating to a reduction of healthcare costs. The prototype operates in the kHz (20-100) range of frequencies and uses noncavitational and nonthermal levels of ultrasound energy. Read More

Outlier response to anti-PD1 in uveal melanoma reveals germline MBD4 mutations in hypermutated tumors.

Nat Commun 2018 05 14;9(1):1866. Epub 2018 May 14.

Institut Curie, PSL Research University, INSERM U830, DNA Repair and Uveal Melanoma (D.R.U.M.), Equipe labellisée par la Ligue Nationale contre le Cancer, Paris, 75248, France.

Metastatic uveal melanoma is a deadly disease with no proven standard of care. Here we present a metastatic uveal melanoma patient with an exceptional high sensitivity to a PD-1 inhibitor associated with outlier CpG>TpG mutation burden, MBD4 germline deleterious mutation, and somatic MBD4 inactivation in the tumor. We identify additional tumors in The Cancer Genome Atlas (TCGA) cohorts with similar hypermutator profiles in patients carrying germline deleterious MBD4 mutations and somatic loss of heterozygosity.

The double-histidine Cu²⁺-binding motif: a highly rigid, site-specific spin probe for electron spin resonance distance measurements.

Angew Chem Int Ed Engl 2015 May 27;54(21):6330-4. Epub 2015 Mar 27.

Department of Chemistry, University of Pittsburgh, 219 Parkman Avenue, Pittsburgh, PA 15260 (USA).

The development of ESR methods that measure long-range distance distributions has advanced biophysical research. However, the spin labels commonly employed are highly flexible, which leads to ambiguity in relating ESR measurements to protein-backbone structure. Herein we present the double-histidine (dHis) Cu(2+)-binding motif as a rigid spin probe for double electron-electron resonance (DEER) distance measurements. Read More

Cysteine-specific Cu2+ chelating tags used as paramagnetic probes in double electron electron resonance.

J Phys Chem B 2015 Feb 30;119(7):2839-43. Epub 2015 Jan 30.

Department of Chemistry, University of Pittsburgh , 219 Parkman Avenue, Pittsburgh, Pennsylvania 15260, United States.

Double electron electron resonance (DEER) is an attractive technique that is utilized for gaining insight into protein structure and dynamics via nanometer-scale distance measurements. The most commonly used paramagnetic tag in these measurements is a nitroxide spin label, R1. Here, we present the application of two types of high-affinity Cu(2+) chelating tags, based on the EDTA and cyclen metal-binding motifs as alternative X-band DEER probes, using the B1 immunoglobulin-binding domain of protein G (GB1) as a model system.

[Surgical treatment of diffuse adult orbital lymphangioma: two case studies].

J Fr Ophtalmol 2008 Dec;31(10):1006-17

Fondation ophtalmologique Rothschild, Paris.

Purpose: Orbital lymphangioma is a rare vascular malformation; it is a benign but severe anomaly because of its infiltrative, diffuse, and hemorrhagic nature, and its high morbidity rate. Surgical resection is a real challenge on account of the intricate architecture of the lesion. The authors report their surgical experience concerning two cases of diffuse orbital lymphangioma whose diagnosis was established in adulthood and whose surgical treatment was successful. Read More

Luteinizing hormone pulsatility in patients with major ovarian hyperandrogenism.

J Endocrinol Invest 2007 Sep;30(8):636-46

Endocrinology, Pitié-Salpétrière Hospital, 83 boulevard de l'Hôpital, 75013, Paris, France.

Hyperandrogenism and ovulatory dysfunction are common in women with either polycystic ovary (PCOS) or ovarian virilizing tumor. However, contrasting with the numerous studies that have extensively described gonadotropin secretory abnormalities, principally increased LH pulse amplitude and frequency, few studies have concerned gonadotropin secretion in patients with ovarian virilizing tumors; low gonadotropin levels have occasionally been reported, but never extensively studied. The goal of the present study was to further evaluate the pulsatility of LH secretion in women with ovarian virilizing tumor compared with that of PCOS patients. Read More

Eosinophilic angiocentric fibrosis of the sinonasal tract in a male patient with chronic bowel inflammation.

Am J Rhinol 2006 Jan-Feb;20(1):91-4

Department of Otolaryngology Head and Neck Surgery, Soroka University Medical Center, Ben-Gurion University of the Negev, Beer-Sieva, Israel.

Background: Eosinophilic angiocentric fibrosis (EAF) is an uncommon inflammatory fibrosing lesion involving the upper respiratory mucosa, occurring mainly in young to middle aged women (female/male ratio = 2:1). The etiology is unknown; however, severalfactors might play a role in the development of EAF. Among them are prior nasal trauma (in most of the reported cases nasal surgery had been performed afew years prior to diagnosis) and inflammatory or autoimmune etiology (suggested by the ratio and the fact that in many of the reported cases a history of nonspecific allergy was found).

N-MYC amplification, loss of heterozygosity on the short arm of chromosome 1 and DNA ploidy in retinoblastoma.

Eur J Cancer 1996 Apr;32A(4):645-9

Service de Pédiatrie, Paris, France.

Recurrent genetic alterations different from the alteration of the RB1 gene on chromosome 13q14 have been described in retinoblastoma, including structural alterations on the short arm of chromosome 1 and amplification of the N-MYC oncogene. These two genetic alterations are major prognostic factors in neuroblastoma, another embryonic neuro-ectodermal tumour. In order to assess the frequency of these alterations and their possible association with clinical parameters in retinoblastoma, we studied a series of 46 retinoblastoma tumour samples. Read More
