Ultra-sensitive room-temperature operable gas sensors utilizing the photocatalytic activity of Na-doped p-type ZnO (Na:ZnO) nanoflowers (NFs) are demonstrated as a promising candidate for diabetes detection. The flowerlike Na:ZnO nano-particles possessing ultrathin hierarchical nanosheets were synthesized by a facile solution route at a low process temperature of 40 (o)C. It was found that the Na element acting as a p-type dopant was successfully incorporated in the ZnO lattice. Based on the synthesized p-type Na:ZnO NFs, room-temperature operable chemiresistive-type gas sensors were realized, activated by ultraviolet (UV) illumination...

AIM: Precipitation of uric acid (UA) in human urine had caused poor recovery and underestimation of UA in study samples. RESULTS: A UA recovery method was developed for analyzing frozen urine samples that potentially contain precipitated UA. Samples were treated with 3% v/v of a solution containing 8 M potassium hydroxide and 20% v/v of ammonium thioglycolate. The high pH enables rapid dissolution of UA crystals, while the thioglycolate protects UA from oxidation at high pH...

The development of an automated kinetic-catalytic spectrophotometric method for cobalt determination is presented. The method is based on the catalytic effect of Co in the oxidation of hydroxybenzoic acid by H2O2 in basic media. The method has been automated using a multisyringe flow injection system coupled to a monolithic flow conduit called chip (chip-MSFIA). All reagents and sample are simultaneously propelled into the chip to achieve an efficient mixing. The reaction product is monitored at 482nm. The reaction takes place very fast at room temperature, thus the fixed-time method is applied to quantify Co concentration in samples...

It is a significant but challenging task to simultaneously reinforce and functionalize diene rubbers. Inspired by "sacrificial bonds", the authors engineer sacrificial hydrogen bonds formed by pendent urazole groups in crosslinked solution-polymerized styrene butadiene rubber (SSBR) via triazolinedione click chemistry. This post-crosslinking modification reveals the effects of the sacrificial bonds based on a consistent covalent network. The "cage effect" of the pre-crosslinked network facilitates the heterogeneous distribution of urazole groups, leading to the formation of hydrogen-bonded multiplets...

BACKGROUND: Bronchopulmonary dysplasia (BPD) results from alveolar simplification and abnormal development of alveolar and capillary structure. Survivors of BPD display persistent deficits in airflow and membrane and vascular components of alveolar gas diffusion. Despite being the defining feature of BPD, various neonatal hyperoxia models of BPD have not routinely assessed pulmonary gas diffusion. METHODS: To simulate the most commonly-utilized neonatal hyperoxia models, we exposed neonatal mice to room air or ≥90% hyperoxia during key stages of distal lung development: through the first 4 (saccular), 7 (early alveolar), or 14 (bulk alveolar) postnatal days, followed by a period of recovery in room air until 8 weeks of age when alveolar septation is essentially complete...

BACKGROUND: Effective methods for postoperative pain relief are an important concern in outpatient surgery. For arthroscopies we combine a single-shot peripheral nerve block using low-volume, low-concentration ropivacaine with general anesthesia. We hypothesized that the patients would have less postoperative pain and be more rapidly home ready than after general anesthesia alone. METHODS: Patients (American Society of Anesthesiologists I-III, 18-80 years old) scheduled for outpatient arthroscopy on the upper or lower extremity were randomized to have either a combination of peripheral nerve block and general anesthesia (NB + GA, study group) or general anesthesia alone (GA, control group)...

BACKGROUND: Inadequate treatment of pain related to surgery may be associated with complications and prolonged recovery time and increased morbidity and mortality rates. We investigated perioperative pain management in vascular surgery and compared it with the relevant guidelines for the treatment of perioperative pain. METHODS: We conducted a retrospective study on 501 patients who underwent vascular surgery at the University Hospital Split, Croatia. We collected the following data from patients' charts: age, gender, premedication, preoperative patient's physical status, type of surgery, duration of surgery and anesthesia, type of anesthesia, postoperative analgesia, and need for intensive care...

REVIEW
Anne Lee Solevåg, Georg M Schmölzer
Cardiopulmonary resuscitation (CPR) duration until return of spontaneous circulation (ROSC) influences survival and neurologic outcomes after delivery room (DR) CPR. High quality chest compressions (CC) improve cerebral and myocardial perfusion. Improved myocardial perfusion increases the likelihood of a faster ROSC. Thus, optimizing CC quality may improve outcomes both by preserving cerebral blood flow during CPR and by reducing the recovery time. CC quality is determined by rate, CC to ventilation (C:V) ratio, and applied force, which are influenced by the CC provider...
