The effect of silver nanoparticles on biological and corrosion behavior of electrophoretically deposited hydroxyapatite film on Ti6Al4V.

Surface modification of titanium and its alloys has been seriously considered by researchers to improve their biological behaviors, in the past few decades. In present research, hydroxyapatite (HA) based composite coatings with different concentrations of 0, 2, 4, and 6 wt% of silver (Ag) nanoparticles were electrophoretically deposited (EPD) on anodized and non-anodized Ti6Al4V, using a direct current at a voltage of 30 V for 10 min at room temperature. The specimens were then characterized by means of X-ray diffraction (XRD) analysis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS).

Sertraline-Induced Sleep Paralysis: A Case Report.

Major depressive disorder (MDD) is associated with both insomnia and hypersomnia, but it predominantly decreases sleep continuity and leads to a decrease in rapid eye movement (REM) latency, an increase in REM sleep duration, and an increase in REM density. Some of these changes persist even when MDD is treated and can be associated with a recurrence of MDD. Antidepressants can potentially complicate the relationship between REM sleep and depression, as a majority of patients report improved sleep when prescribed selective serotonin reuptake inhibitors (SSRIs) but some case reports mention that SSRIs have been associated with REM inhibition, resulting in decreased REM sleep.

A Case of Olanzapine-Induced Cutaneous Eruption.

BACKGROUND Different medication classes have been implicated in cutaneous eruptions that may lead to significant morbidity and mortality. In drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome, the patient may initially present with a cutaneous eruption and hematologic abnormalities which can lead to acute visceral organ involvement if the offending drug is not discontinued. There is also a potential for long-term sequelae such as autoimmune disorders.

Analyzing public sentiment toward GMOs via social media between 2019-2021.

Genetically modified organisms or GMOs offer significant advantages in food production, including increased yield, decreased pesticide usage, and better disease resistance. However, adoption and public sentiment toward GMOs is highly variable. Without positive sentiment toward GMOs, consumption of GMO-based foods may not have an adequate market for further investment.
