In clinical laboratories, the diagnosis of parasite diseases can sometimes be challenging for non-expert microbiologists. Indeed, in spite of the advent of the molecular biology, macroscopic and microscopic examinations still remain essential. Nonetheless, it is usually not automated and requires great skills to complete the correct diagnosis. It is not infrequent that inert elements mislead to erroneous diagnoses. Through three different concrete examples, this article aims at underscoring the actual risk of parasite misidentification and at highlighting the systematic approach to be conducted in order to enable reliable diagnosis.

A device architecture based on heterostructure WSe/organic semiconductor field-effect transistors (FETs) is demonstrated in which ambipolar conduction is virtually eliminated, resulting in essentially unipolar FETs realized from an ambipolar semiconductor. For p-channel FETs, an electron-accepting organic semiconductor such as hexadecafluorocopperphthalocyanine (FCuPc) is used to form a heterolayer on top of WSe to effectively trap any undesirable electron currents. For n-channel FETs, a hole-accepting organic semiconductor such as pentacene is used to reduce the hole currents without affecting the electron currents.

Undesirable loss of open-circuit voltage and current of metal halide perovskite (MHP) solar cells are closely associated with defects, so theoretical calculations have been often performed to scrutinize the nature of defects in bulk of MHPs. Yet, exploring the properties of defects at surfaces of MHPs is severely lacking given the complexity of the surface defects with high concentrations. In this study, I (Pb) antisite defects, namely one Pb (I) site being occupied by one I (Pb) atom at the surfaces of the FAPbI (FA=CH(NH)) material, are found to create electron (hole) traps when the surfaces with I (Pb) antisite defects are negatively (positively) charged.

We experimentally investigated the asymmetric dual-grating-gate plasmonic terahertz (THz) detector based on an InGaAs-channel high-electron-mobility transistor (HEMT) in the gate-readout configuration. Throughout the THz pulse detection measurement on the fabricated device, we discovered a new detection mechanism called the "3D rectification effect" at the positive gate bias application, which is a cooperative effect of the plasmonic nonlinearities in the channel with the diode nonlinearity in the heterobarrier between the InGaAs channel layer and the InAlAs spacer/carrier-supply/barrier layers, resulting in a giant enhancement of the detector responsivity. We also found that an undesired long-tail waveform observed on the temporal pulse photoresponse of the device is due to trapping of carriers to the donor levels in the silicon -doped carrier-supply layer when they tunnel through the barrier to the gate and can be eliminated completely by introducing the so-called inverted-HEMT structure.

Sepsis, a systemic inflammatory response syndrome resulting from an uncontrolled inflammatory reaction to infection, remains without a definitive cure despite therapeutic advancements. Mesenchymal stem cells (MSCs), renowned for their capacity to alleviate inflammation and modulate the immune system, have emerged as a potential treatment avenue for sepsis. In sepsis pathophysiology, hyperactivated neutrophils release extracellular neutrophil traps (NETs).

Background: Earthquakes are potentially traumatic natural disasters due to their destructive nature, and huge impacts, producing scenes of horror, undesirable and uncontrollable results. Children are affected mainly by earthquakes not only physically but also psychologically. We aimed to evaluate the rates of probable PTSD and related factors in children and adolescents after the February 6 Kahramanmaras earthquake.
