Background: Although current guidelines recommend a 5 mm surgical margin for the excision of melanoma in situ (MIS), increasing evidence has shown this may be suboptimal to achieve tumor clearance.
Objective: To evaluate margins required for optimal cure rates with excision of MIS on the head and neck and investigate tumor and/or patient factors in those requiring >5 mm margins to achieve tumor clearance.
Methods: A retrospective chart review was performed on 846 (807 primary and 39 recurrent) MIS cases on the head and neck treated in the authors' dermatologic surgery department over a 126-month (10.
Background: Females and minorities have been underrepresented in clinical research despite legislative efforts, including in hidradenitis suppurativa (HS) and psoriasis (PsO) clinical trials.
Objective: To identify differences in demographic breakdowns of HS and PsO patients between health care settings to uncover any causative health disparities.
Methods: This study reports racial, ethnic, and sex of HS and PsO patient populations across the emergency department (ED), inpatient, clinical trial, and registry settings.
Glioblastoma multiforme (GBM) is the most lethal brain cancer subtype, often advanced by the time of initial diagnosis. Existing treatment modalities including surgery, chemotherapy and radiation have been stymied by recurrence, metastasis, drug resistance and brain targetability. Here, we report a geometrically distinct Au(i) complex ligated by N^N-bidentate ligands and supported by a N-heterocyclic ligand that modulates mitochondrial morphology to inhibit GBM and .

Objective: To understand how the public views medical spas compared with physician's offices as places to receive cosmetic procedures with a focus on safety.
Background: Hidradenitis suppurativa (HS) fistulas are likely to persist without surgical intervention. Hypertonic saline (HTS), a venous sclerosant, disrupts the endothelial lining leading to occlusion and fibrosis when used for venous insufficiency.
Objective: To evaluate the efficacy and tolerability of HTS sclerotherapy for HS fistulas.

Objectives: OTA/AO 61C pelvic ring injuries are vertically unstable because of complete sacral fractures combined with anterior ring injury. The objective of this study was to compare the biomechanical characteristics of 4 transsacral screw constructs for posterior pelvic ring fixation, including one that uses a novel fixation method with a pair of locked washers with interdigitating cams.
Methods: Type C pelvic ring disruptions were created on 16 synthetic pelvis models.

The development of oxidant-free gold-catalyzed cross coupling reactions involving aryl halides have been hamstrung by the lack of gold catalysts capable of performing oxidative addition at Au(I) centers. Herein, we report the development of novel tricoordinate Au(I) catalysts supported by N,N-bidentate ligands and ligated by phosphine or arsine ligands for C-H functionalization without external oxidants to form biaryls with no homocoupling. The unsymmetrical character of the Au(I) catalyst is critical to facilitating this necessary orthogonal transformation.

Reconstruction in this region must maintain nearby free margins to ensure optimal cosmetic and functional outcomes. Large defects may require a flap using lateral or inferior tissue reservoirs.
View Article and Find Full Text PDFJAK (janus kinase) inhibitors are becoming increasingly prescribed for various conditions from dermatologic diseases to graft versus host disease in bone marrow transplant recipients. This class of drugs has been found to be truly life-changing for many, though they are not without potential adverse effects. While JAK inhibitors have not been shown to significantly increase the risk of non-melanoma skin cancer (NMSC) in large scale clinical trials, NMSC is one of the most concerning possible adverse events, and there have been several reported cases of aggressive squamous cell carcinomas, especially in our already immunosuppressed patient populations.

Three herbaceous nonhost species, Beta vulgaris, Lactuca sativa, and Capsicum annuum, and three grapevine species displaying different level of resistance (Vitis vinifera [susceptible], Vitis riparia [partially resistant] and Muscadinia rotundifolia [totally resistant]) where inoculated by P. viticola using a controlled leaf disk inoculation bioassay.

They inhibit the cytochrome bc1 complex of mitochondrial respiration. Soon after their introduction onto the market in 1996, QoI fungicide-resistant isolates were detected in field plant pathogen populations of a large range of species.

The study comprised two study phases: the pilot study phase and the main study phase. During open, nonrandomized pilot study, the optimal administration period was tested.
View Article and Find Full Text PDFPlasmopara viticola, the causal agent of grapevine downy mildew, is an obligate biotrophic oomycete that grows in the intercellular spaces of host tissues and develops haustoria in the cells. Histological observations are the most effective methods to visualize and quantify the development of the infection structures. We chose two staining techniques leading to high resolution and contrast between parasite structures and host-plant tissues with a minimum of sample preparation: Blankophor and KOH-aniline blue fluorescent stainings.

View Article and Find Full Text PDFRegistration using the least-squares cost function is sensitive to the intensity fluctuations caused by the blood oxygen level dependent (BOLD) signal in functional MRI (fMRI) experiments, resulting in stimulus-correlated motion errors. These errors are severe enough to cause false-positive clusters in the activation maps of datasets acquired from 3T scanners. This paper presents a new approach to resolving the coupling between registration and activation.
