Pilot Study of the Effects of Paced Breathing on Measures of Convergent and Divergent Thinking.

Background: The ability of the autonomic nervous system's stress response to impair aspects of cognitive flexibility is known. However, the ability to modulate the sympathetic response and improve these cognitive impairments via nonpharmacological intervention, such as paced breathing (PB), requires further investigation.

Objective: To better elucidate the effects of PB on cognition.

Advanced basal cell carcinoma: What dermatologists need to know about treatment.

The treatment of advanced basal cell carcinoma (BCC) often requires therapies beyond local surgical excision or radiation due to the invasiveness of the tumor. Historically, cytotoxic chemotherapy was used to treat advanced BCC, but with limited data, no standard regimens were established. The discovery of cyclopamine, a natural inhibitor in the Hedgehog pathway, led to the development of the 2 currently approved Hedgehog inhibitors, vismodegib and sonidegib.

Chemical Profiling of A-to-I RNA Editing Using a Click-Compatible Phenylacrylamide.

Straightforward methods for detecting adenosine-to-inosine (A-to-I) RNA editing are key to a better understanding of its regulation, function, and connection with disease. We address this need by developing a novel reagent, N-(4-ethynylphenyl)acrylamide (EPhAA), and illustrating its ability to selectively label inosine in RNA. EPhAA is synthesized in a single step, reacts rapidly with inosine, and is "click"-compatible, enabling flexible attachment of fluorescent probes at editing sites.

Bim expression in endothelial cells and pericytes is essential for regression of the fetal ocular vasculature.

Apoptosis plays a central role in developmental and pathological angiogenesis and vessel regression. Bim is a pro-apoptotic Bcl-2 family member that plays a prominent role in both developmental and pathological ocular vessel regression, and neovascularization. Endothelial cells (EC) and pericytes (PC) each play unique roles during vascular development, maintenance and regression.

A Retrospective Case-Matched Cost Comparison of Surgical Treatment of Melanoma and Nonmelanoma Skin Cancer in the Outpatient Versus Operating Room Setting.

Background: To date, no study has used authentic billing data in a case-control matched fashion to examine the cost of treating skin cancer in different settings.

Objective: To compare the cost of surgical treatment of skin cancer in the outpatient versus operating room setting using matched cases based on patient and skin cancer characteristics.

Methods: ICD-9 diagnosis codes for skin cancers were used to find patients who had a malignant excision current procedural terminology code in the operating room setting during 2010 to 2014.

Endothelium Expression of Bcl-2 Is Essential for Normal and Pathological Ocular Vascularization.

Bcl-2 is an anti-apoptotic protein with important roles in vascular homeostasis and angiogenesis. Mice globally lacking Bcl-2 (Bcl-2 -/-) are small in stature and succumb to renal failure shortly after weaning as a result of renal hypoplasia/cystic dysplasia. We have shown that Bcl-2 -/- mice displayed attenuated retinal vascular development and neovascularization.

Pruritic rash on trunk.

The patient had been treated with topical antifungals and steroids without relief, but a more detailed history suggested a serious infectious etiology.

Renal medullary carcinoma metastatic to the scalp.

A 40-year-old woman presented to the Brooke Army Medical Center Emergency Department complaining of 2 episodes of gross hematuria. Computed tomography and intravenous pyelogram revealed a right renal mass. A radical nephrectomy was performed with complete excision of the mass with negative margins on histological examination.

Subcutaneous nodules with sporotrichoid spread.

Background: Mycobacterium marinum is an atypical mycobacterium found worldwide and associated with swimming pools and aquariums. Infections typically present with subcutaneous nodules and lymphangitis.

Case Report: A 61-year-old female presented with a two-month history of subcutaneous nodules.

Mycobacterium marinum infection: a case report and review of the literature.

Mycobacterium marinum is a nontuberculous mycobacteria that is often acquired via contact with contaminated salt or fresh water. We present a case of a 67-year-old man who developed several solitary nontender nodules on his hands and forearm after working on the underside of his boat. In addition, we provide a review of the literature and discuss how this infection is acquired, the underlying pathogenesis, the cutaneous and histologic findings, the differential diagnosis, the diagnostic methods, and the various treatment options.
