Photoproduction of K^{+}K^{-} Pairs in Ultraperipheral Collisions.

K^{+}K^{-} pairs may be produced in photonuclear collisions, either from the decays of photoproduced ϕ(1020) mesons or directly as nonresonant K^{+}K^{-} pairs. Measurements of K^{+}K^{-} photoproduction probe the couplings between the ϕ(1020) and charged kaons with photons and nuclear targets. The kaon-proton scattering occurs at energies far above those available elsewhere.

Search for exotic decays of the Higgs boson to a pair of pseudoscalars in the and final states.

A search for exotic decays of the Higgs boson () with a mass of 125 to a pair of light pseudoscalars is performed in final states where one pseudoscalar decays to two quarks and the other to a pair of muons or leptons. A data sample of proton-proton collisions at corresponding to an integrated luminosity of 138 recorded with the CMS detector is analyzed. No statistically significant excess is observed over the standard model backgrounds.

Drug Promotions Between Ethics, Regulations, and Financial Interests.

Background: The promotion of the latest medicines produced by the pharmaceutical industry is an important issue both from an ethical point of view (the level of accessibility, the way research is carried out) and from the point of view of marketing and especially from the lobbying issues raised.

Areas Of Uncertainty: The ethical dilemmas raised by the promotion of new drugs revolve between the need to discover new molecules important for treating a wide range of diseases and the need to establish a battery of ethical rules, absolutely necessary for regulations in the field to be compliant with all ethical principles.

Data Sources: A literature search was conducted through PubMed, MEDLINE, Plus, Scopus, and Web of Science (2015-2023) using combinations of keywords, including drugs, medical publicity, and pharma marketing plus ethical dilemma.

Cognitive Outcomes in Nonacute Patients With Schizophrenia Treated With Long-Acting Injectable Antipsychotics Versus Oral Antipsychotics.

Background: Patients with schizophrenia often face challenges related to cognitive function, affecting their daily functioning and overall quality of life. The choice of antipsychotic treatment may play a crucial role in determining cognitive outcomes.

Study Question: Our study aimed to investigate whether there was a difference in cognitive ability between the patients with schizophrenia receiving oral antipsychotics (OAP) versus long-acting injectable antipsychotics (LAI-APs).

Brain Abnormalities in Schizophrenia: A Comparative Imagistic Study.

: Neuroimaging reveals a link between psychiatric conditions and brain structural-functional changes, prompting a paradigm shift in viewing schizophrenia as a neurodevelopmental disorder. This study aims to identify and compare structural brain changes found during the first schizophrenia episode with those found after more than 5 years of illness. : This prospective study involved 149 participants enrolled between 1 January 2019 and 31 December 2021.

Intrathecal ropivacaine versus bupivacaine in a non-obstetric population- A meta-analysis and trial sequential analysis.

Background And Aims: Intrathecal bupivacaine is used for anaesthesia and analgesia but is associated with hypotension. Ropivacaine is an alternative drug that may have fewer cardiotoxic and neurotoxic events. This meta-analysis investigated whether intrathecal ropivacaine is associated with reduced hypotension as compared to bupivacaine.

Resveratrol Activates Antioxidant Protective Mechanisms in Cellular Models of Alzheimer's Disease Inflammation.

Resveratrol is a natural phenolic compound with known benefits against neurodegeneration. We analyzed in vitro the protective mechanisms of resveratrol against the proinflammatory monomeric C-reactive protein (mCRP). mCRP increases the risk of AD after stroke and we previously demonstrated that intracerebral mCRP induces AD-like dementia in mice.

Systemic inflammatory cytokine profiles in patients with gout during flare, intercritical and treat-to-target phases: TNFSF14 as new biomarker.

Introduction: Untreated gout is characterised by monosodium urate (MSU) crystal accumulation responsible for recurrent flares that are commonly separated by asymptomatic phases. Both phases are inflammatory conditions of variable intensity. Gout flares are self-limited inflammatory reactions involving multiple mediators.

Early referral to nephrological care improves long-term survival and hospitalization after dialysis initiation, independent of optimal dialysis start - a call for harmonization of reimbursement policies.

Early treatment of kidney disease can slow disease progression and reduce the increased risk of mortality associated with end-stage kidney disease. However, uncertainty exists whether early referral (ER) to nephrological care or an optimal dialysis start impacts patient outcome after dialysis initiation. We determined the effect of ER and suboptimal dialysis start on the 3-year mortality and hospitalizations after dialysis initiation.

The resolution of the weak-exchange limit made rigorous, simple and general in binuclear complexes.

The correct interpretation of magnetic properties in the weak-exchange regime has remained a challenging task for several decades. In this regime, the effective exchange interaction between local spins is quite weak, of the same order of magnitude or smaller than the various anisotropic terms, which generates a complex set of levels characterized by spin mixing. Although the model multispin Hamiltonian in the absence of local orbital momentum, , is considered good enough to map the experimental energies at zero field and in the strong-exchange limit, theoretical works pointed out limitations of this simple model.

Iodine Status in Cyprus and Neighboring Countries: A Review Article.

Despite the implementation of global iodine supplementation initiatives in the past decade, the problem of iodine deficiency persists as a significant public health concern in numerous countries. Although cretinism is now rare in developed countries, iodine deficiency can still lead to less severe cognitive deficits, which can negatively impact academic achievement, intellectual capacity, and work productivity. There is a scarcity of studies regarding the status of Cyprus, and the global database does not have any information pertaining to the prevalence of iodine deficiency in Cyprus.
