Mona Mahmoud AbouSamra, Alaa Hamed Salama
Tolnaftate is a thiocarbamate antifungal drug which is therapeutically active against dermatophytes that cause various forms of tinea. Due to the small amount of tolnaftate released from ordinary ointment bases and insufficient penetration through the infected skin layers the need to incorporate the drug in a more suitable pharmaceutical form has evolved. A provesicular system is one such form that can solve these problems. Once in contact with the skin, dilution with moisture occurs and the provesicular system rapidly transforms into a vesicular one...

BACKGROUND AND OBJECTIVES: Patients with in-transit melanoma metastasis have longer median survival than patients with distant metastatic disease. Furthermore, local disease control is an important endpoint for symptom management. The treatment of unresectable loco-regional recurrence or in-transit disease has been historically managed with a combination of treatments including surgery, radiotherapy, isolated limb infusion or perfusion as well as systemic therapies. Intralesional PV-10 has been used at Peter MacCallum Cancer Centre since 2010, and the current report presents a retrospective analysis of patient outcomes, reporting the response rates, durability of responses, and observed toxicities...

Sanjiv S Agarwala
The US Food and Drug Administration has been rapidly approving new checkpoint inhibitors and targeted therapies for melanoma and other tumors. Recently, it approved the first intralesional therapy, talimogene laherparepvec (T-VEC), for the treatment of metastatic melanoma lesions in the skin and lymph nodes. Several other intralesional therapies (PV-10, interleukin-12 electroporation, coxsackievirus A21 [CVA21]) are entering later-stage testing. Locally injected agents have clearly shown their ability to produce local responses that can be durable...

In order to process large-aperture aspherical mirrors, we designed and constructed a tri-station machine processing center with a three station device, which bears vectored feed motion of up to 10 axes. Based on this processing center, an aspherical mirror-processing model is proposed, in which each station implements traversal processing of large-aperture aspherical mirrors using only two axes, while the stations are switchable, thus lowering cost and enhancing processing efficiency. The applicability of the tri-station machine is also analyzed...

Pemphigus vulgaris (PV) is an autoimmune epidermal blistering disease in which autoantibodies (IgG) are directed against the desmosomal cadherin desmoglein 3 (Dsg3). In order to better understand how PV IgG alters desmosome morphology and function in vivo, PV patient biopsies were analyzed by structured illumination microscopy (SIM), a form of super-resolution fluorescence microscopy. In patient tissue, desmosomal proteins were aberrantly clustered and localized to PV IgG-containing endocytic linear arrays...

Effective treatment of sites contaminated with dense non-aqueous phase liquids (DNAPLs) requires detailed understanding of the microbial community responses to changes in source zone strength and architecture. Changes in the spatial and temporal distributions of the organohalide-respiring Dehalococcoides mccartyi (Dhc) strains and Geobacter lovleyi strain SZ (GeoSZ) were examined in a heterogeneous tetrachloroethene- (PCE-) DNAPL source zone within a two-dimensional laboratory-scale aquifer flow cell. As part of a combined remedy approach, flushing with 2...

INTRODUCTION: Isolation of pulmonary veins (PVs) and the posterior left atrium (LA) can be safely performed by radiofrequency hot balloon (RHB)-based box isolation. However, data on long-term effects for the treatment of atrial fibrillation (AF) by the use of this method remain limited. METHODS AND RESULTS: We treated 238 patients with paroxysmal AF (194 male; age. 62.6 ± 9.4 years) by RHB ablation. During 6.2-year (75 months) follow-up, 154 (64.7%) patients were free from atrial tachyarrhythmias (ATAs) without antiarrhythmic-drugs (AADs)...

Polycythemia vera (PV) is a chronic myeloproliferative neoplasm that is associated with a substantial symptom burden, thrombohemorrhagic complications, and impaired survival. A decade after the seminal discovery of an activating mutation in the tyrosine kinase JAK2 in nearly all patients with PV, new treatment options are finally beginning to emerge, necessitating a critical reappraisal of the underlying pathogenesis and therapeutic modalities available for PV. Herein, we comprehensively review clinical aspects of PV including diagnostic considerations, natural history, and risk factors for thrombosis...

OBJECTIVES: The value of Barrett's esophagus (BE) surveillance based on the histological diagnosis of low-grade dysplasia (LGD) remains debated given the lack of adequate risk stratification. The aim of this study was to evaluate the predictive value (PV) of SOX2 expression for neoplastic progression in BE patients. METHODS: We conducted a case-control study within a prospective cohort of 720 BE patients. Patients with neoplastic progression, defined as the development of high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC), were classified as cases and patients without neoplastic progression were classified as controls...

Sleep apnea is more frequently experienced in neonatal life. Here we investigated the causal contribution of NOX2-derived oxidative stress in the prefrontal cortex (PFC) to neurodevelopmental alterations and psychiatric anxiety in a neonatal rat model of sleep apnea. Neonatal postnatal day 5 (P5) rats were exposed to long-term intermittent hypoxia (LTIH) or room air (RA) for 10 days. In the PFC, we determined the impact (I) of LTIH exposures on NADPH oxidase-2 (NOX2) expression and oxidative stress (II) of pharmacological NOX2 inhibition on LTIH-induced neurodevelopmental alterations in the P14 and P49 rats...

BACKGROUND: We have previously shown that right-sided low-level tragus nerve stimulation (LL-TS) is an effective approach for the treatment of atrial fibrillation (AF) induced by rapid atrial pacing (RAP) and acts by preventing the loss of atrial connexins (Cxs). Whether a left-sided approach would achieve the same effect remains unknown. OBJECTIVE: We hypothesized that left-sided LL-TS would inhibit AF by preserving atrial Cxs as effectively as right-sided LL-TS...

Members of the diffusible signal factor (DSF) family are a novel class of quorum sensing (QS) signals in diverse Gram-negative bacteria. Although previous studies have identified RpfF as a key enzyme for the biosynthesis of DSF family signals, many questions in their biosynthesis remain to be addressed. In this study with the phytopathogen Xanthomonas campestris pv. campestris (Xcc), we show that Xcc produces four DSF-family signals (DSF, BDSF, CDSF and IDSF) during cell culture, and that IDSF is a new functional signal characterized as cis-10-methyl-2-dodecenoic acid...

Pemphigus vulgaris (PV) is a severe autoimmune disease in which autoantibodies against the desmosomal cell adhesion molecules desmoglein (Dsg) 1 and Dsg3 cause intraepidermal blister formation. Mechanistically, the fundamental question is still unresolved whether loss of cell cohesion is a result of (1) direct inhibition of Dsg interaction by autoantibodies or (2) intracellular signaling events, which are altered in response to antibody binding and finally cause desmosome destabilization. We used atomic force microscopy (AFM) to perform Dsg3 adhesion measurements on living keratinocytes to investigate the contributions of direct inhibition and signaling to loss of cell cohesion after autoantibody treatment...
