An adrenal crisis (Addisonian crisis) is an acute life-threatening complication of adrenal insufficiency. It occurs when hydrocortisone demand is not met by supplementation in the context of an infection - often gastrointestinal, fever, trauma, acute psychological or physical stress. Symptoms of weakness, nausea, muscle/joint pain and drowsiness may develop out of robust health within few hours. If overlooked, treated too late, with insufficient dose or route of application, there exists a considerable risk of mortality...

BACKGROUND/AIMS: Healing of mesangioproliferative glomerulonephritis involves degradation of excess extracellular matrix, resolution of hypercellularity by apoptosis and phagocytosis of apoptotic cells. Integrin receptors participate in the regulation of phagocytosis. In mice deficient for alpha8 integrin (Itga8-/-) healing of glomerulonephritis is delayed. As Itga8 is abundant in mesangial cells (MC) which are non-professional phagocytes, we hypothesized that Itga8 facilitates phagocytosis of apoptotic cells and matrix components by MC...

18p deletion syndrome is a rare chromosomal disease caused by deletion of the short arm of chromosome 18. By using cytogenetic and SNP array analysis, we identified a girl with 18p deletion syndrome exhibiting craniofacial anomalies, intellectual disability, and short stature. G-banding analysis of metaphase cells revealed an abnormal karyotype 46,XX,del(18)(p10). Further, SNP array detected a 15.3-Mb deletion at 18p11.21p11.32 (chr18:12842-15375878) including 61 OMIM genes. Genotype-phenotype correlation analysis showed that clinical manifestations of the patient were correlated with LAMA1, TWSG1, and GNAL deletions...

Distraction osteogenesis is an effective method for generating large amounts of bone in situ for treating pathologies such as large bone defects or skeletal malformations, for instance leg-length discrepancies. While an optimized distraction procedure might have the potential to reduce the rate of complications significantly, our knowledge of the underlying mechanobiological processes is still insufficient for systematic optimization of treatment parameters such as distraction rate or fixation stiffness. We present a novel numerical model of lateral distraction osteogenesis, based on a mechanically well-controlled in vivo experiment...

Two-dimensional transitional metal dichalcogenide (TMDC) field-effect transistors (FETs) are proposed to be promising for devices scaling beyond silicon-based devices. We explore the different effective mass and bandgap of the channel materials and figure out the possible candidates for high-performance devices with the gate length at 5 nm and below by solving the quantum transport equation self-constantly with the Poisson equation. We find that out of the 14 compounds, MoS₂, MoSe₂, and MoTe₂ may be used in the devices to achieve a good subthreshold swing and a reasonable current ON-OFF ratio and delay...

In the current era of checkpoint inhibitors, some patients with metastatic melanoma have shown a significant improvement in survival. However, optimization of immunotherapy is an ongoing effort. Monocyte-derived dendritic cell (MODC) vaccines have been shown in clinical trials to be safe and capable of inducing tumor-specific immunity as well as occasional objective clinical responses. Here, we conducted a three-arm pilot clinical study in 15 patients with metastatic melanoma to evaluate three types of MODC vaccines, differing only by strategies of tumor antigen delivery...

BACKGROUND: Postoperative pillar pain (deep-seated wrist pain worsened by leaning on the heel of the hand) sometimes occurs after carpal tunnel release (CTR), leading to weakness in the hand and delayed return to work. Increased pain sensitivity has been found to be associated with worse symptoms and poorer treatment response in a number of chronic musculoskeletal conditions, but few studies have investigated the association of pain sensitization with pillar pain after CTR. QUESTIONS/PURPOSES: (1) Is preoperative pain sensitization in patients with carpal tunnel syndrome (CTS) associated with increased severity of pillar pain after open CTR? (2) What other demographic, electrophysiological, or preoperative clinical characteristics are associated with pillar pain after CTR? METHODS: Over a 35-month period, one surgeon performed 162 open carpal tunnel releases...

We evaluated the effectiveness of a problem-based learning (PBL) health literacy program aimed to improve health literacy, health empowerment, navigation efficacy, and health care utilization among immigrant women in Taiwan. We employed a quasi-experimental design that included surveys at the baseline, immediately after the intervention, and 6 months after the intervention. The intervention group participated in a 10-session PBL health literacy program and the comparison group did not. Results showed that 6 months after the intervention, the intervention group had significantly fewer ER visits and hospitalizations than the comparison group...

Multidrug-resistant (MDR) and extensively-drug-resistant (XDR) Gram-negative bacteria have emerged as a major threat to human health globally. This has resulted in the "re-discovery" of some older antimicrobials and development of new agents, however resistance has also rapidly emerged to these agents. Areas Covered: Here we describe recent developments in resistance to three of the most important last-line antimicrobials for treatment of MDR and XDR Gram negatives: fosfomycin, colistin and ceftazidime-avibactam...

Bisphosphonates are stable structural analogs of pyrophosphate, which suppress the activity of osteoclasts, leading to decreased bone resorption. They are essential medications in the treatment of osteoporosis. Osteonecrosis of the jaw is a serious adverse effect of bisphosphonate therapy. The prevalence of bisphosphonate-related osteonecrosis of the jaw varies from 0% to 28%, and it can be triggered by dental extraction and trauma. Root canal therapy can delay, or even eliminate, the need for tooth extraction, and therefore, may reduce the risk of bisphosphonate-related osteonecrosis of the jaw...

We present a broadly tunable single-frequency ytterbium-doped fiber laser. Its broadband tunability is made possible by low resonator losses. The wavelength is determined by a grating filter, while the single-frequency regime is achieved by filtering the longitudinal modes in a fiber ring resonance filter. We obtained a tuning range from 1023 nm to 1107 nm. A feedback loop driving a fiber stretcher actuated by a piezo-element prevents mode hopping. Based on the coherent delayed self-heterodyne interferometry, the laser linewidth is estimated to be 600 Hz with feedback open and 11...

We demonstrate a polarization-multiplexed, single-laser system for terahertz (THz) time-domain spectroscopy without an external delay line. The fiber laser emits two pulse trains with independently adjustable repetition rates, utilizing only one laser-active section and one pump diode. With a standard fiber-coupled THz setup and a polarization-multiplexed optical amplifier, we are able to measure transients with a spectral bandwidth of 1.5 THz and a dynamic range of 50 dB in a measurement time of 1 s. Based on the novel laser architecture, we call this new approach single-laser polarization-controlled optical sampling, or SLAPCOPS...
