With skin lesions that have failed previous treatments, consideration for an atypical mycobacteria, specifically Mycobacterium marinum, infection should be suspected. Importance of the history cannot be stressed as this is a clue that the patient may have been inoculated and infected in the field environment. A marine with chronic right knee plaque for 3 yr that first appeared after a field exercise at The Basic School but worsened despite treatment with clindamycin, TMP-SMX, and incision and drainage in 2012...

The chloroplast houses photosynthesis in all green plants, and is therefore of fundamental importance to the viability and productivity of plants, ecosystems, and agriculture. Chloroplasts are, however, extremely vulnerable to environmental stress, on account of the inherent volatility of oxygenic photosynthesis. To counteract this sensitivity, sophisticated systems of chloroplast stress acclimation have evolved, and many of these involve broad proteome changes. Here, we provide an overview of the interlocking and mutually dependent mechanisms of abiotic stress-induced chloroplast proteome remodelling...

Vaginal birth after caesarean (VBAC) delivery remains a controversial topic, and one for which there is a lack of robust data to guide clinicians and parturients regarding their best option for mode of delivery in a subsequent pregnancy. In many developed countries the trend observed in recent years is that of progressively reduced VBAC rates, and hence increased use of elective repeat caesarean section (ERCS). This factor has contributed, more than any other, to the disproportionately high caesarean section (CS) rates in many countries...

When the bioavailability of a drug increases, a corresponding increase in the levels of that drug in the bloodstream occurs. With this, drug efficacy is augmented and the dosage required to yield a specific therapeutic effect diminishes comparably. Until recently, only a few methods have proven effective in enhancing drug bioavailability, among which are the disaggregation of micronized molecules, the use of timedrelease and topical preparations, mechanization, polymorph and crystal form selection, drug solubilisation, and the use of nanotechnology...

The Oncology Nursing Society (ONS) has conducted several member surveys that included questions about staffing but has not established nurse-patient ratios, given the number and complexity of variables that must be considered. The 2016 ONS member survey showed that staffing was the most frequently cited challenge in the practice setting. With the implementation of ONS Communities in 2017, members have the opportunity to network and connect about issues. Staffing in chemotherapy infusion centers has been a frequent topic...

Photosensitization by drugs is a problem of increasing importance in modern life. This phenomenon occurs when a chemical substance in the skin is exposed to sunlight. Photosensitizing drugs are reported to cause severe skin dermatitis, and indeed, it is generally advised to avoid sunbathing and to apply sunscreen. In this context, the nonsteroidal anti-inflammatory drug (NSAID) diclofenac is a photosensitive drug, especially when administered in topical form. In this work, efforts have been made to design and study an innovative pro-drug/pro-filter system containing diclofenac and the UVA filter avobenzone in order to develop a safer use of this topical drug...

Phototoxicity occurs when UV irradiation causes otherwise benign compounds to become irritant, sensitizers or even genotoxic. This toxicity is particularly a concern after topical application and in dermatological programs where skin irritation can be incompatible with the desired therapeutic outcome. This brief article establishes that the intrinsic Property Forecast Index (iPFI) can be used to evaluate the probability of a compound being phototoxic and gives medicinal chemists a practical tool to handle this liability...

Onychomycosis is a fungal infection of the nail primarily caused by the dermatophytes Trichophyton rubrum and Trichophyton mentagrophytes. The topical-based treatment of onychomycosis remains a challenge because of the difficulty associated with penetrating the dense, protective structure of the keratinized nail plate. Tavaborole is a novel small-molecule antifungal agent recently approved in the United States for the topical treatment of toenail onychomycosis. The low molecular weight, slight water solubility, and boron chemistry of tavaborole maximize nail penetration after topical application, allowing for effective targeting of the infection in the nail bed...

CONTEXT: - There has been a paradigm shift in the understanding of molecular pathogenesis of lung cancer. A number of oncogenic drivers have been identified in non-small cell lung carcinoma, such as the epidermal growth factor receptor ( EGFR) mutation and anaplastic lymphoma kinase ( ALK) gene rearrangement. Because of the clinical presentation at an advanced stage of disease in non-small cell lung carcinoma patients, the use of minimally invasive techniques is preferred to obtain a tumor sample for diagnosis...

Mass spectrometry is an important tool used by many scientists throughout the world. Nonetheless, feedback on the strengths and limitations of current software is often restricted to anecdote rather than formal inquiry. Over the course of 100 interviews over the state of mass spectrometry software, surprising patterns coalesced on several topics: perception of the frontier, perception of software quality, and differences between commercial and non-profit environments. Most notably, interviews suggested a substantial schism between user satisfaction with current software and developer perceptions of software quality...

50 years ago, Northway described Broncopulmonary Dysplasia (BPD) in preterm infants exposed to mechanical ventilation. Since then, their survival has increased, nevertheless a "new BPD" has appeared and its incidence has not diminished. One of the characteristics of this pathology is the the abnormal vascular remodeling, which in its most severe expression is known as Pulmonary Hyper tension (PH); with an incidence of 17% in patients with BPD, which is proportional to the severity of the disease (33% in severe BPD), and as mortality factor (up to 48% 2-year mortality in PH-BPD)...

BACKGROUND: ADHD (Attention-deficit/hyperactivity disorder) is a common neurodevelopmental disorder that manifests itself during childhood with various combinations of symptoms, including inattention, hyperactivity and impulsivity. Research has shown that psychiatric comorbidities play an important role in the development of suicidal behavior and, recently, there has been a growing interest in a possible association between ADHD and suicide during both childhood and adulthood. Furthermore, some authors have shown a relationship between pharmacological treatments and suicide in patients affected by ADHD...

RADA16-I (Ac-(RADA)4 -CONH2 ) is a widely investigated self-assembling peptide (SAP) in the biomedical field. It can undergo ordered self-assembly to form stable secondary structures, thereby further forming a nanofiber hydrogel. The modification of RADA16-I with functional peptide motifs has become a popular research topic. Researchers aim to exhibit particular biomedical signaling, and subsequently, further expand its applications. However, only a few fundamental reports are available on the influences of the peptide motifs on self-assembly mechanisms of designer functional RADA16-I SAPs...

BACKGROUND: In order to optimize outcomes of novel therapies for cerebellar ataxias (CAs), it is desirable to start these therapies while declined functions are restorable: i.e. while the so-called cerebellar reserve remains. OBJECTIVE: In this mini-review, we tried to define and discuss the cerebellar reserve from physiological and morphological points of view. METHOD: The cerebellar neuron circuitry is designed to generate spatiotemporally organized outputs, regardless of the region...
