Regenerative medicine, specifically bone marrow aspirate concentrate (BMAC) and platelet-rich plasma (PRP), has become a novel adjunct that orthopedic surgeons have started to use with surgical rotator cuff repairs (RCR). Thus, we are conducting this systematic review to determine if either RCRs with BMAC alone or with BMAC and PRP result in superior functional outcomes. We conducted a comprehensive search using five databases including PubMed, Web of Science, Embase, Scopus, and Cochrane.

The spotted lanternfly, Lycorma delicatula White (1845) (Hemiptera: Fulgoridae), is an invasive insect that was first reported in North America in Berks County, Pennsylvania, in 2014. It is a polyphagous phloem feeder that attacks over 70 plant species, threatening the agricultural, lumber, and ornamental industries of North America. Infestations of the pest have been reported in several U.

This review is devoted to trapping mass spectrometry wherein ions are confined by electromagnetic fields for prolonged periods of time within limited volume, with mass measurement taking place within the same volume. Three major types of trapping mass spectrometers are discussed, specifically radiofrequency ion trap, Fourier transform ion cyclotron resonance and Orbitrap. While these three branches are intricately interwoven with each other over their recent history, they also differ greatly in their fundamentals, roots and historical origin.

Background: In-stent restenosis (ISR) complicates 20-30% of percutaneous coronary interventions (PCI) with bare metal stent (BMS) implantation. Although the widespread use of drug eluting stents (DES) across Europe caused a considerable reduction of BMS implantations, their number is still lower than the number of BMS implantations in several countries.

Aim: The clinical presentation of ISR has not been well characterissed.

Using the mouse maximal electroshock-induced seizure model, indicative of tonic-clonic seizures in humans, the present study was aimed at characterizing the interaction between remacemide and valproate, carbamazepine, phenytoin, and phenobarbital. Isobolographic analysis indicated additive interactions between remacemide and valproate, carbamazepine, and phenytoin (for all fixed ratios of tested drugs: 1:3, 1:1, and 3:1). Additivity was also observed between remacemide and phenobarbital applied in proportions of 1:1 and 3:1.

The aim of this review was to assemble current literature data on nuclear factor kappa B (NF-kappaB). Many authors believe that NF-kappaB, a transcription factor, has essential influence on the regulation of numerous genes in the organism. In this review, we have focused on the role of NF-kappaB and its target genes in the central nervous system functioning.

Felbamate (2-phenyl-1,3-propanediol dicarbamate), a representative of novel antiepileptic drugs (AESs), proved to have broad-spectrum anticonvulsive activity. Particularly beneficial efficacy was found against partial seizures and Lennox-Gastaut syndrome. Therefore, felbamate started to be indicated not only as an adjunctive antiepileptic drug but also in monotherapy.

Epilepsy belongs to common diseases of the brain. It affects approximately 1% of the population. The aim of epilepsy therapy is to keep the patient free of seizures without interfering with normal brain function.

Although the significant progress in pharmacotherapy of epilepsy during last decade was achieved, about one third of patients are resistant to the current treatment. When the monotherapy is not efficient, the polytherapy should be applied. Zonisamide (ZNS) is a new antiepileptic drug (AED) efficient in treating refractory epilepsy.

Patients with drug resistant epilepsy represent about 40% of the whole population of epileptic patients. These patients require more than one antiepileptic drug. In animal models of epilepsy, it is possible to determine which combinations produce supra-additive anticonvulsive effects with minimal or even no adverse reactions.

Experimental and clinical data indicate that epilepsy and seizures lead to neuronal cell loss and irreversible brain damage. This neurodegeneration results not only in the central nervous system dysfunction but may also be responsible for the decreased efficacy of some antiepileptic drugs (AEDs). The aim of this review was to assemble current literature data on neuroprotective properties of AEDs.
