Abstract
The aim of this article is to investigate the potential cytotoxic and antitumor effects of the resonant electromagnetic fields (rEMFs) derived from the 1H NMR spectrum of the Ph3Sn(Mercaptonicotinic)SnPh3 complex (SnMNA). The ability of the complex's rEMFs to induce leiomyosarcoma (LMS) cell death and to recess tumor (leiomyosarcoma) development in Wistar rats was evaluated. The effects of the simultaneous administration of the SnMNA complex at extremely low concentrations and exposure to its rEMFs was also investigated. The emission of the 1H NMR spectrum of the complex alone or in a combination with low ineffective doses of the complex decreased LMS cell viability mainly through apoptosis. Moreover, the results from the in vivo experiments showed a significant prolongation of life expectancy in tumor-bearing rats exposed to the rEMFs alongside a deceleration in tumor growth rate. We speculate that the rEMFs of a biologically active substance could exert similar biological effects as the substance itself, mainly when is combined with extremely low ineffective concentrations of the substance.

Abstract
Due to its rarity and unique biological traits, as well as its growing financial value, milk of dairy Greek small ruminants is continuously attracting interest from both the scientific community and industry. For the construction of the present dataset, cutting-edge proteomics methodologies were employed, in order to investigate and characterize, for the first time, the milk whey proteome from the two indigenous Greek goat breeds, Capra prisca and Skopelos. In total 822 protein groups were identified in milk whey of the two breeds, The present data are further discussed in the research article “Milk of Greek sheep and goat breeds; characterization by means of proteomics” [1].

Abstract
AIM This study was carried-out to investigate the effect of four different silver substances (S1, S2, S3, and S4) on burn wound healing in a rat model. MATERIALS AND METHODS One hundred and eighty Wistar rats were used. Animals were randomized into six groups to receive no treatment (CG, control group), and local application of the solvent of silver substances (SG, solvent group), as well as of the four silver substances (EG1-EG4 groups for substances S1-S4, respectively). On days 0, 3, 6, 12, 21, and 31 following burn wound infliction, the size and healing progress of each wound were recorded and evaluated by means of clinical evaluation, planimetry and histological examination. RESULTS According to our findings lower infection rates, as well as significantly accelerated wound healing and faster re-epithelialization were recorded in EG1, EG2, and EG4 compared to the other groups. DISCUSSION The use of S1, S2, and S4 substances proved to be an effective treatment of burn wounds that ensured better outcomes compared to the control and solvent groups, as well as with the use of S3 substance. Nevertheless, they failed to produce short-term healing of the full-thickness burn. Further research is required to examine the possibility of speeding the treatment of full-thickness burns by these complexes in order to reduce healing time to acceptable limits and prevent the need for surgery.

Abstract
INTRODUCTION Benign prostate hyperplasia (BPH) has been treated with various types of electromagnetic radiation methods such as transurethral needle ablation (TUNA), interstitial laser therapy (ILC), holmium laser resection (HoLRP). In the present study, the effects of a noninvasive method based on the exposure of patients with BPH to a pulsative EM Field at radiofrequencies have been investigated. MATERIALS AND METHODS Twenty patients with BPH, aging 68-78 years old (y.o), were enrolled in the study. Patients were randomly divided into two groups: the treatment group (10 patients, 74.0 ± 5.7 y.o) treated with the α-blocker Alfusosin, 10 mg/24 h for at least 4 weeks, and the electromagnetic group (10 patients, 73.7 ± 6.3 y.o) exposed for 2 weeks in a very short wave duration, pulsed electromagnetic field at radiofrequencies generated by an ion magnetic inductor, for 30 min daily, 5 consecutive days per week. Patients of both groups were evaluated before and after drug and EMF treatment by values of total PSA and prostatic PSA fraction, acid phosphate, U/S estimation of prostate volume and urine residue, urodynamic estimation of urine flow rate, and International Prostate Symptom Score (IPSS). RESULTS There was a statistically significant decrease before and after treatment of IPSS (P < 0.02), U/S prostate volume (P < 0.05), and urine residue (P < 0.05), as well as of mean urine flow rate (P < 0.05) in patients of the electromagnetic group, in contrast to the treatment group who had only improved IPSS (P < 0.05). There was also a significant improvement in clinical symptoms in patients of the electromagnetic group. Follow-up of the patients of this group for one year revealed that results obtained by EMFs treatment are still remaining. CONCLUSION Pulsed electromagnetic field at radiofrequencies may benefit patients with benign prostate hyperplasia treated by a non-invasive method.

Abstract
BACKGROUND Catecholamines play an important role in platelet activation and aggregation, epinephrine being the most potent one. Catecholamines are substantially increased during stress, exercise or smoking and could result in clinically important platelet activation if their action was not rapidly regulated. In the present study the possible fast regulation of epinephrine-induced platelet aggregation by its metabolic degradation products is investigated. MATERIALS AND METHODS Human platelet rich plasma (hPRP) and washed rabbit platelets(wRP) were used for the study. The platelets irreversible aggregation induced by epinephrine and ADP were monitored by an aggregometer prior to and after the addition of the catecholamines degradation products metanephrine, 3-methoxy-4-hydroxy-phenyl-glycole-aldehyde (MHPGA),3-methoxy-4-hydroxy-phenyl-mandelic acid (VMA) 3,4-dihydroxy phenyl glycole (DHPG),3,4-Dihydroxy-phenyl-glycole-aldehyde (DHPGA) and the trimethoxy-phenyl-methyl-piperazine(TMP), a known free radical scavenger and calcium antagonist. Linoleic acid-lipoxygenase reaction, in vitro was monitored in the presence and absence of VMA. RESULTS Metabolic degradation products possessing a methoxy group at position 3 of the phenolic ring markedly inhibited epinephrine and ADP-induced platelet aggregation at microM concentrations. The most potent inhibitor of both agonists was metahephrine, followed by MHPGA and VMA. TMZ also inhibited platelet aggregation at concentrations similar to VMA. Dihydroxy-phenyl compounds failed to induce any inhibition. None of the substances tested induced any aggregatory effect even at high concentrations (1 mM). VMA significantly inhibited linoleic acid-lipoxygenase reaction at 0.1 microM. CONCLUSIONS Results indicate that catecholamines' degradation products possessing methoxy (-OCH3) groups can rapidly inhibit in vitro and ex vivo epinephrine-induced platelet aggregation. The inhibitory effects of methoxy phenolic derivatives on epinephrine-induced platelet aggregation may possibly be attributed to their free radical scavenging properties. There is substantial evidence to conclude that an internal rapid autoregulation of epinephrine-induced platelet aggregation, caused by its metabolic degradation products, takes place in vivo.
