DNA/GO functional structures have been widely used in biosensors, biomedicine and materials science. However, most studies about DNA/GO functional structures do not take into account the coexistence of both large unoxidized and oxidized regions on GO sheets. This special local structure provides the boundary region, which is the junction area between unoxidized and oxidized regions, and exhibits a special amphiphilic property of the GO sheets. Here based on molecular dynamics simulations, our results predict that the adsorption efficiency of long strand ssDNA molecules adsorbed on GO is 43%. Further analysis has shown that the ssDNA adsorption behaviors on the GO surface are more likely to start in the boundary region, even for 20 mer ssDNA molecules. Looking into the adsorption dynamic process we can see that the hydrogen bonds between ssDNA and GO are very active and easily broken and formed, especially for the boundary region of the GO surface, resulting in easy capture and adsorption of the ssDNA molecules on this region. The result provides insightful understanding of the adsorption behavior of ssDNA molecules on this amphiphilic GO surface and is helpful in the design of DNA/GO functional structure-based biosensors.Dermatologists are required to keep track of a high volume of items after each patient encounter, including biopsies, laboratory tests, cultures, and imaging. In residency, there is a complicating factor of transitioning care to different providers. Residents currently utilize a variety of handoff and organizational practices. Residency provides an opportunity to become familiar with different handoff and organizational practices to take forward in one's career.Patients consider pruritus and scaling to be the most bothersome symptoms of psoriasis. Psoriatic plaques on the knees and elbows are widely considered difficult to treat because of the thicker stratum corneum, which reduces skin hydration and topical absorption. Betamethasone dipropionate (BD) spray 0.05% is a topical steroid with demonstrated efficacy in treating plaque psoriasis. Post hoc analyses of 2 phase 3 trials were done to assess the efficacy of BD spray in relieving the symptom of itching and improving the signs of erythema, scaling, and plaque elevation on plaques located on the knees and elbows vs its vehicle and an augmented BD (AugBD) lotion 0.05%. Betamethasone dipropionate spray reduced the incidence of pruritus, with approximately half of patients who reported itching at baseline showing complete itch relief by day 4. Betamethasone dipropionate spray also reduced the signs of psoriasis on knee and elbow plaques in more patients than AugBD lotion at day 4, though the differences were not statistically significant. Efficacy was similar between the 2 formulations on days 8 and 15.  https://www.selleckchem.com/products/6-benzylaminopurine.html  Betamethasone dipropionate spray rapidly relieved2 of the most bothersome symptoms of psoriasis and improved psoriatic signs in hard-to-treat knee and elbow plaques.Fitzpatrick skin type (FST) was developed to assess the propensity of the skin to burn during phototherapy, but it also is commonly used by providers as means of describing constitutive skin color and ethnicity. We conducted an anonymous survey of dermatologists and dermatology trainees to evaluate how providers use FST in their clinical practice. Although providers should be cognizant of conflating race/ethnicity with FST, the original intent of FST also should be emphasized in medical school and resident education.Hypersensitivity reactions to orthopedic implanted materials exist but are rare. Potential allergens include metals and bone cement components. Clinical presentation can include localized or generalized cutaneous reactions and noncutaneous reactions. Preimplant patch testing for implant hypersensitivity reactions (IHRs) is only recommended if metal allergy is strongly suspected; postimplant patch testing to relevant allergens can be completed if symptoms are concerning for implant hypersensitivity. The decision to remove or revise an orthopedic implant should be made as a joint decision between the surgeon and patient.The use of superpotent topical corticosteroids (TCSs) for the treatment of psoriasis is widely practiced, especially for expedient lesion resolution. However, their continued use in managing this chronic condition is limited because of labelling restrictions, concerns of side effects, and a paucity of data to support long-term management strategies. Halobetasol propionate (HP) is an effective short-term superpotent TCS. A novel HP lotion 0.01% formulation has been developed using a polymeric matrix technology that allows for uniform delivery of optimally sized particles onto the skin surface. The polymeric matrix and emulsion help to keep the skin hydrated and provide more efficient delivery of halobetasol into the epidermis.The personal statement is a narrative written by an applicant to residency programs to discuss his/her interests and express his/her personality, but it is unclear how the personal statement impacts the dermatology residency application process. The aim of this study was to analyze personal statements from applicants to a dermatology program at a major academic institution to identify common themes and determine if certain themes were associated with successful matching. All personal statements submitted to the dermatology residency program at UNC School of Medicine (Chapel Hill, North Carolina) during the 2012 application cycle (N=422) were analyzed to identify 9 common themes of content. Certain themes differed in prevalence between matched and unmatched applicants. Further investigation is needed to elucidate the impact of personal statement themes and other application content on the residency selection process.Most patients with psoriasis have limited disease that should be manageable with topical treatment. However, psoriasis often is resistant to topical treatment. The aim of our study was to determine if patients using psoriasis-resistant topical treatments can be effectively treated with topicals under conditions promoting adherence. During this open-label, randomized, single-center clinical study, 12 patients with moderate psoriasis that previously failed topical treatment were selected and treated with desoximetasone spray 0.25% for 2 weeks. Six patients were randomized to receive twice-daily telephone call reminders to further encourage good adherence. Disease severity was assessed by the visual analog scale for pruritus, psoriasis area and severity index (PASI), total lesion severity score (TLSS), and investigator global assessment (IGA). At the end of the study, most patients improved in most scores. Therefore, apparent resistance to topical treatment often is due to poor adherence and can be overcome, at least over the short term.
