New Formulation

In this paper, a new formulation of nasal spray was set up based on the extract of lemon pulp, obtained by using a new solid-liquid technology of extraction, added to pure Aloe juice, soluble propoli, and essential oils of Ravensara and Niaouly. It was tested in a clinical study in which 100 subjects were recruited for a period of one month. Nasal scraping was used for collecting samples and after the application of the May-Grünwald Giemsa standard technique, glass slides were analysed by using optical microscope with a 1000x oil immersion. A control group constituted of ten people was recruited as control and this group was administered with physiological solution (saline solution). The comparison of results obtained before and after the application of nasal spray showed a total reduction of eosinophils granulocytes and mast cells; clinical data were confirmed by improvement of clinical pictures of patients. The lemon-based nasal spray was a good alternative to conventional medicine for the treatment of perennial and seasonal allergic and vasomotor rhinopathy.

Background. One of the most common surgical complications is nausea. Regarding the contradictory findings on the effect of aromatherapy with peppermint on the severity of nausea, in the present study, we aimed at comparing the effect of aromatherapy with 10% and 30% peppermint essential oils on the severity of nausea in surgical patients. Methods. This single-blind randomized controlled trial was conducted at the surgical ward of Imam Reza Hospital in Kermanshah, Iran. A total of 120 patients undergoing abdominal surgery were randomly divided into three groups of 10% peppermint, 30% peppermint, and control (40 patients in each group) using a random number table. In each of the intervention groups, 0.2 ml of 10% and 30% peppermint essential oil was inhaled. In the control group, the same amount of distilled water colored with green food coloring was inhaled. The severity of nausea was measured by nausea visual analog scale (NVAS) before and 10 minutes after the intervention. Results. In the 10% peppermint group, the mean severity of nausea before the intervention was 52.3 ± 13.7 out of 100, which reduced to 40.5 ± 13.5 after the intervention (p<0.001). In the 30% peppermint group, the mean severity scores of nausea before and after the intervention were 60.2 ± 15.0 and 39.7 ± 12.4, respectively (p<0.001). In the control group, the mean severity scores of nausea before and after the intervention was not statistically significant. There was no significant difference between the two intervention groups in terms of the mean severity of nausea after the intervention. Conclusions. It can be concluded that 10% and 30% peppermint essential oils are equally effective on the severity of nausea.

A rehabilitative program for patients who lose strength and muscle mass along with the ability to perform intensive exercises is lacking. We developed a 3-week training program based on neuromuscular electrical stimulation (NMES) using a RSQ1 device (modulated current resulting from the overlapping of two-component currents) for RSQ1 electrostimulation to improve strength parameters of the quadricep femoris muscles and compare its effectiveness to isometric training. Nineteen university students were randomly divided into the NMES group (10 sessions) and the control group who trained. We measured the circumference of the thigh, as well as peak torques of the flexor and extensor muscles before and after the start and after the end of the training program. Both tested training programs gave similar results. Differences between measured parameters were not significant except for differences in the peak torques of the knee flexors (9.9% for left limb; p = 0.2135 vs. 7.8% for rift limb; p = 0.2135) and the circumference of the left thigh—2% for both (left p = 0.5839 and right p = 0.1088). Comparable results of the tested training programs suggest that NMES is a good alternative for people who cannot perform exercises, but want to maintain or improve their physical fitness.

Purpose:to assess the effect of ultraviolet (UVA) crosslinking of Bioplast plastic material (silicon-dried human cornea) on its biomechanical stability and effectiveness for keratoplasty in corneal ulcers. Material and methods. To determine the maximum rehydration time, 12 Bioplast samples were incubated in physiological solution (NaCl 0.9 %) for 12 hours and monitored for thickness using optical coherence tomography (OCT Spectralis, Heidelberg Engineering). After the epithelium was scarified rehydrated corneas were treated withof 0.1% riboflavin solution for 30 minutes, and after it 8 rehydrated samples (experimental group) were treated with UVA for 30minutes (wavelength 370 nm, power 3 mW/cm2) using a UV-X device system (IROC AG, Switzerland). In the control group (4 rehydrated samples), no UVA crosslinking was performed. The elastic-strength indicators of the experimental and control group samples were assessed by applying uniaxial tension using a deformation machine (Autograph AGS-H, Japan). To examine the patients (presented in clinical examples)before and after keratoplasty with Bioplast subjected to UVA crosslinking, a set of standard ophthalmic tests was used. Results.Rehydration of Bioplast was the most intensive in the first three hours of incubation, during which time tissue thickness increased uniformly by 50–55 μm/hour to 700–710 μm, while further incubation showed no significant additional effect on the fluid content in the cornea. After UVA crosslinking, the strength indices and the elastic modulus of the rehydrated Bioplast samples significantly increased in comparison with the control group. Clinical examples demonstrate the effectiveness of modified Bioplast for organ-preserving penetrating keratoplasty in case of perforatedcorneal ulcer. Conclusion. UVA crosslinking of rehydrated Bioplast increases its biomechanical stability. The data of laboratory studies and the first clinical tests demonstrate that modified Bioplast may be an effective replacement of native donor cornea in urgent keratoplasty of perforated ulcers.

Abstract This study aimed to evaluate the cause-effect relationship between canal preparation with ProTaper Universal (PTU) system and dentinal defects formation using micro-computed tomography (micro-CT) analysis. Forty mesial canals of mandibular molars with a type II Vertucci's canal configuration were scanned at an isotropic resolution of 14.16 µm. The sample was assigned to an experimental (n = 30) and a control (n = 10) groups, and the mesial canals were prepared with PTU system up to F2 instrument. The specimens from the experimental group were scanned and the cross-section images of the mesial roots, before and after preparation, were screened to identify the presence of dentinal defects. In the control group, the specimens were sectioned perpendicularly to the long axis of the root into 1-mm-thick slices (n = 80) and examined under optical microscope. Once a dentinal defect was detected, the slice was scanned through micro-CT. In the experimental group, dentinal micro-cracks were observed in 4,828 slices (24.04%). In all cross-section images, dentinal defects identified in the postoperative images were already present in the corresponding preoperative image. In the control group, 13 out of 80 slices (16.25%) had at least one dentinal defect visualized under stereomicroscopy, which was identified after a further micro-CT scanning. Micro-CT showed reliability as similar as optical microscopy in detecting dentinal defects, adding the possibility of tracking the dentinal tissue, before and after canal preparation, and providing a clear visualization of micro-cracks. Root canal preparation with PTU system did not induce the formation of new dentinal defects.

ABSTRACT Objective: The aim of this study was to evaluate the use of acetazolamide combined with different agents as intracanal medication in late reimplanted rat teeth. Materials and Methods:In 100 Wistar rats, divided into 5 groups of 20, one of the following medications was used: Acetazolamide liquid (AL); AL with calcium hydroxide powder (ALHC); acetazolamide powder with AL; acetazolamide powder with physiological solution; and calcium hydroxide with physiological solution (control). At 30 and 60 days after reimplantation, the animals were sacrificed, tissues were processed, and cuts were stained with hematoxylin and eosin. An optical microscope was used to determine the following: percentage of inflammatory root resorption (RRI); percentage of substitute root resorption (RRS); and presence of ankylosis. The data obtained was submitted for statistical analysis. Results: Group ALHC had a significantly higher RRS than the control group at 60 days (P = 0.01). Group AL showed significantly less ankylosis than the other groups, including the control, at 30 days. AL showed results similar to those of the control group with respect to RRS. Conclusion:Acetazolamide has the potential to be an effective intracanal medication.

Background. Moxibustion has a therapeutic effect of reducing swelling and relieving pain in patients with rheumatoid arthritis (RA) but its mechanism is uncertain. Objective. To evaluate the effect of moxibustion on serum levels of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in patients with RA and to explore the possible mechanism of moxibustion. Methods. This study involved 46 RA patients who had fulfilled the inclusion criteria and were randomly assigned to a treatment group and a control group in an equal ratio. The control group was treated with methotrexate or leflunomide, while the treatment group received methotrexate or leflunomide and moxibustion at ST 36 (Zusanli), BL 23 (Shenshu), and Ashi points. Patients’ clinical symptoms, RA-associated serum markers, and serum levels of TNF-α, IL-1β, HIF-1α, and VEGF were compared in the two groups before and after intervention. Statistical analysis was performed using SPSS 21.0 statistical software. Results. 37 of 46 RA patients eventually completed the whole treatment course. Compared with the control group, the treatment group significantly improved the clinical symptoms (P<0.05) but with no significant differences in RA-associated serum markers (P>0.05). There were significant differences in TNF-α and IL-1β among the groups after 8 weeks of treatment (P<0.05). HIF-1α and VEGF were decreased in the treatment group after therapy (P<0.05). VEGF was reduced in the control group (P<0.05), while HIF-1α was not significantly improved (P>0.05). The reductions of HIF-1α and VEGF in the treatment group were superior to the control group (P<0.05). Conclusions. Moxibustion enhanced the anti-inflammatory and analgesic effects of conventional medicine and can enhance the effect of conventional medicine, downregulating HIF-1α/VEGF contents to inhibit angiogenesis.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.
