The direct in situ synthesis of cadmium sulfide (CdS) nanowires (NWs) was presented by direct synthesis of CdS NWs on the gold surface of an interdigitated electrode (IDE). In this work, we investigated the effect of a strong oxidant on the surfaces of the CdS NWs using X-ray photoelectron spectroscopy, transmission electron microscopy, and time-of-flight secondary ion mass spectrometry. We also fabricated a parylene-C film as a surface passivation layer for in situ-synthesized CdS NW photosensors and investigated the influence of the parylene-C passivation layer on the photoresponse during the coating of parylene-C under vacuum using a quartz crystal microbalance and a photoanalyzer...

EDITORIAL
Tiny Jaarsma
Approximately 60% to 87% of patients with heart failure (HF) report sexual problems, and numbers as low as 31% of HF patients younger than 70 have normal sexual function. When compared with healthy elders, the amount of perceived sexual dysfunction might be similar (around 56%), but patients with HF are reporting more erectile dysfunction (ED) and also perceive that their HF symptoms (20%) or HF medication (10%) is the cause for their problems. The prevalence of ED is highly prevalent in men with cardiac disease and reported in up to 81% of cardiac patients, compared with 50% in the general older population...

Melanized or black fungi are a heterogeneous group of fungi causing cutaneous to systemic diseases with high mortality. These fungi are rarely reported as agent of human infections primarily due to difficulties in their classical identification. In this study we examined using molecular methods and MALDI-TOF MS the diversity of melanized fungi (MF) isolated from patients in 19 medical centers in India. Overall, during a 4-year period, 718 (5.3%) clinical specimens yielded MF. Of these, 72 (10%) isolates had clinical significance and were identified primarily by sequencing the ITS and LSU regions...

BACKGROUND: filamentous fungi are the most important pathogens causing fungal rhinosinusitis (FRS). Current laboratory diagnosis of FRS pathogens mainly relies on phenotypic identification by culture and microscopic examination, which is time-consuming and expertise-dependent. Although matrix -assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been employed to identify various fungi, its performance for the identification of FRS fungi is less clear...

Astronauts have recently been discovered to have impaired vision, with a presentation that resembles syndromes of elevated intracranial pressure (ICP). This syndrome is considered the most mission critical medical problem identified in the past decade of manned spaceflight. We recruited five men and three women who had an Ommaya reservoir inserted for the delivery of prophylactic central nervous system chemotherapy, but were free of their malignant disease for at least 1 year. ICP was assessed by placing a fluid-filled 25 ga butterfly needle into the Ommaya reservoir...

Matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) imaging mass spectrometry (IMS) enables localization of analytes of interest along with histology. More specifically, MALDI-IMS identifies the distributions of proteins, peptides, small molecules, lipids, and drugs and their metabolites in tissues, with high spatial resolution. This unique capacity to directly analyze tissue samples without the need for lengthy sample preparation reduces technical variability and renders MALDI-IMS ideal for the identification of potential diagnostic and prognostic biomarkers and disease gradation...

A new wave of portable biosensors allows frequent measurement of health-related physiology. We investigated the use of these devices to monitor human physiological changes during various activities and their role in managing health and diagnosing and analyzing disease. By recording over 250,000 daily measurements for up to 43 individuals, we found personalized circadian differences in physiological parameters, replicating previous physiological findings. Interestingly, we found striking changes in particular environments, such as airline flights (decreased peripheral capillary oxygen saturation [SpO2] and increased radiation exposure)...

Nitric oxide (NO) occurs naturally in mammalian biochemistry as a critical signaling molecule and exhibits antithrombotic, antibacterial, and wound-healing properties. NO-forming biodegradable polymers have been utilized in the development of antithrombotic or antibacterial materials for biointerfacial applications, including tissue engineering and the fabrication of erodible coatings for medical devices such as stents. Use of such NO-forming polymers has frequently been constrained by short-term release or limited NO storage capacity and has led to the pursuit of new materials with improved NO release function...
