Apomorphine is a non-specific dopamine receptor agonist that has been used in the treatment of some diseases and mental disorders. Its use has particularly well documented in Parkinson＇s disease（PD）. The dopaminergic agonists like apomorphine are related to oxidative processes that could induce cell damage and the functional impairment of some structures in the brain. However, most information about apomorphine in literature is focused on the improvement of the motor problems characteristic of PD, but little is known about the effects on cognitive behaviors and brain structures indirectly related to motor function. The presence of dopaminergic receptors in the hippocampus has recently been discovered, in connection with cognitive behaviors like learning and memory, these receptors are needed in neuronal plasticity. There has been a growing interest to know if this structure could be compromised by the effect of apomorphine and elucidate if part of the cognitive impairment present in the PD is due to the effect of apomorphine. In this mini-review, we summarized how apomorphine has been used since its creation, we discuss the latest information about its effect on the hippocampus and also the future perspectives to fully understand the effects of this compound.

Brain metastasis are the most common intracranial malignancy in the adult population. Their incidence has increased dramatically over the last 20 years, as a result of the increasing number of cases stemming from lung and breast cancer together with the higher cancer survival rates due to diagnostic and therapeutic advances. More than 40%of cancer patients develop brain metastases during the course of their disease: specifically, they appear in 50%of patients with lung cancer, more than 25% of patients with breast cancer, and 20% of patients with melanoma. Diagnosis is made using different imaging approaches, such as computed tomography and magnetic resonance imaging, accompanied by clinical manifestations and a history of malignancy supporting the diagnosis of a brain metastasis. Current treatment options should be oriented to the patient's current performance, the number of intracranial and extracranial lesions, and related factors. Although surgical resection and whole-brain radiotherapy have been standard treatments for many years, numerous treatment modalities have become more easily available and accepted worldwide, producing more favorable and reliable results. Among these is stereotactic radiosurgery, and the latest clinical trials support this treatment.

Flavor violating Higgs signals, such as the top FCNC decay t→ch0 and the LFV Higgs decay h0→τμ, have been studied at the LHC. These signals can arise within the general Two-Higgs Doublet Model （THDM）, where each Higgs doublet couples to all fermion types through Yukawa matrices Yf 1 and Y f2 . The Yukawa matrices can be assumed to have the same form or they could have different structures. In this paper we study the case when both Yf1 and Y f2 have completely different forms, but in such a way that they complement to produce a specific hermitian mass matrix. We find that for specific four-zero textures, the flavor violating Higgs couplings depend only on the free parameters tan β, γf and the fermion masses. We use the current bounds on the low energy processes to derive constraints on the heavy Higgs boson mass, tanβand γf Then, we use these constraints to evaluate the LFV Higgs decays, which reach branching ratios that could be tested at the LHC.

This research presents a novel way of labelling human activities from the skeleton output computed from RGB-D data from vision-based motion capture systems. The activities are labelled by means of a Compound Hidden Markov Model. The linkage of several Linear Hidden Markov Models to common states, makes a Compound Hidden Markov Model. Each separate Linear Hidden Markov Model has motion information of a human activity. The sequence of most likely states, from a sequence of observations, indicates which activities are performed by a person in an interval of time. The purpose of this research is to provide a service robot with the capability of human activity awareness, which can be used for action planning with implicit and indirect Human-Robot Interaction. The proposed Compound Hidden Markov Model, made of Linear Hidden Markov Models per activity, labels activities from unknown subjects with an average accuracy of 59.37%, which is higher than the average labelling accuracy for activities of unknown subjects of an Ergodic Hidden Markov Model (6.25%), and a Compound Hidden Markov Model with activities modelled by a single state (18.75%).

Using zinc oxide (ZnO) powder and quartz rods as solid sources and molecular hydrogen (H2) as reactant gas, ZnO: SiOx composites were grown by hot filament chemical vapor deposition (HFCVD) technique. The absorbance spectra showed the formation of ZnO: SiOx composite in the studied temperature range. The crystalline quality of the ZnO lattice in the structure of the composite gradually lost by increasing the substrate temperature. Visible emission from blue to near-infrared region was found in the photoluminescence spectra of the composite formed at 1,100 °C. The contribution of blue, green, yellow and orange emissions present in the photoluminescence spectra of the composite formed at 1,100 °C was attributed to recombination centers produced by the presence of point defects in the structure of ZnO network. This result suggests that the ZnO in the ZnO: SiOx composite obtained at substrate temperature of 1,100 °C has an amorphous phase.
