The Brain

This article presents the investigation of structural parameters of the brain in 67 patients aged 47.23 ± 2.64 years, whose duration of the disease was 13.27 ± 0.75 (from 2 to 19) years. The control group included 18 healthy individuals of the same age (47.84 ± 0.36 years), whose selection was carried out based on the anamnesis and the absence of hypothyroidism and hypertension. According to the data we discussed in our previous publications, during neuropsychological testing we registered memory deterioration in patients with hypertension assessed by the test for learning 10 words according to the method proposed by A.R. Luria (p <0.05), as well as serial counting by the Matisse scale (p <0.05). The patients with hypothyroidism were found as demonstrating attention deficiency (p <0.05) by applying the method of "Selectivity of attention" (G. Munsterberg test). For more detailed assessment, we used Schulte tables, the result of which demonstrates the state of the domain of the patient's executive functions and proves the instability of attention. The analysis of the results showed that taking into account the interaction between hypertension and hypothyroidism, the most affected cognitive domains were memory and attention, respectively (p <0.05). To diagnose cognitive and mnestic disorders of all groups, we used MR imaging, measured the transverse dimensions of the medial, lateral (temporal horn) and vertical perihippocampal spaces, and evaluated the volume of gray matter (cortex) of the frontal lobe of the brain in 3 zones. The measurements were performed in the right and left hemispheres. There was a significant increase in the indices of the medial and upper perihippocampal right and left in the patients in group III compared with the groups I and II. The lateral perihypocampal index did not differ significantly in the three groups (p> 0.05). Thus, taking into account the interaction of factors (hypertension and hypothyroidism), the patients were found to have an increase in perihippocampal indices (p> 0.05). Based on the data in table 2, in the patients of group I the average value of the frontal lobe was 634.06 ± 10.92. In the patients of group II, the average value of the frontal lobe was 638.6 ± 7.82, and in the patients of group III, the average value of the frontal lobe was 601.3 ± 3,325. There was no statistically significant difference between groups I and II (p = 0.05). But groups I and III demonstrated statistically significant difference between the indicators (p <0.05). We also found a statistically significant difference between groups II and III (p <0.05). Thus, in patients with hypertension, hypothyroidism and hypertension with concomitant hypothyroidism, an increase in perihippocampal indices, a decrease in the volume of gray matter (cortex) of the frontal lobe of the brain (right and left), significantly exceeded possible (involutional or otherwise). Thus, the results of the study indicate that in cases of isolated hypertension, hypothyroidism, and in the comorbidity of hypertension and hypothyroidism, there has been detected a significant acceleration of atrophic processes.

The Impact

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

This study aimed to evaluate the effects of nano mineral-supplemented diet on sow productivity. The data were estimated by several parameters consisting of piglet live ratio at newborn stage and weaning stage, piglet weight at newborn stage and weaning stage, metal content in piglet livers. The results showed that live ratio of newborn piglets in group III was highest (93.44 ± 2.83%) comparing with other groups. However, there was no significant difference of live ratio in piglets at weaning stage between nano mineral-supplemented groups with control. The birth weight of piglets in nano mineral-supplemented groups was similar to control group. The birth weight of piglets in nano mineral-supplemented groups was ranged from 1,361.61 ± 47.37 grams (group II) to 1,410.48 ± 44.28 grams (group I). However, the average weight of weaned pigs in groups III and IV was higher than other groups (6,772.92 ± 105.47 grams and 6,818.87 ± 89.59 grams). Moreover, the amount of Fe, Cu, Zn, Mn in piglet liver from nano mineral-supplemented groups have been found to be lower than those in control group. These results revealed that the supplement of nano minerals for sows promoted the reproductive performance of sows and reduced mineral content in the liver of piglets.

Abstract Background The biology of claudins is a rapidly evolving field, and many intriguing questions remain unanswered. Although it had been assumed that the reason there are ≥24 isoforms of claudin is that each one has distinct permeability properties. The nephron displays a wide spectrum of claudins, whose distribution varies in each tubular segment. In diabetic nephropathy and glomerulonephritis the gene expression of claudin-1, is markedly upregulated in the podocyte, accompanied by a tighter filtration slit diaphragm (cell-cell junction made by the glomerular podocytes) and the appearance of TJ-like structures between the foot processes causing further podocytes injury and proteinuria. Aim of the work to assess urinary claudin -1 level as a marker of podocyte injury in patients with proteinuria. Patients and Methods it is a case control study which was conducted upon 90 subjects who were divided into three groups: group I included 30 patients with type II DM, group II included 30 patients with glomerulonephritis and group III had 30 healthy subjects as controls. Urinary claudin-1 level was measured by Enzyme linked Immunosorbent Assay (ELISA) Results In this study, we found that urinary claudin-1 level was significantly higher in diabetics group and GN group than in control group. In comparison between GN group and diabetic group, we found that urinary claudin-1 level was higher in GN group than in diabetics group but with no statistically significant difference between the two groups. Conclusion urinary claudin-1 level was significantly higher in diabetics and GN group and has positive correlation with uACR. So it can be used as marker of podocytes injury and proteinuria

This work assess serum levels of soluble Fas form (sFas) in patients with different stages of laryngeal squamous cell carcinoma(LSCC) to investigate its prognostic significance. We correlate its levels with the morphological changes of peripheral blood cells via buffy coat examinatin. The study population included 70 patients clinically diagnosed and pathohistologically confirmed LSCC in addition to 20 healthy controls. According to TNM classification 33(47.1%) patients were in stage I (group I) and 24(34.3%) in stage II (group II), 13(18.5%) in stage III (group III). The results revealed that the mean serum level of sFas (pg/ml) in the control group was 51.2, in group I was 66.33, in group II was 81.33 and in group III was 112.45. Statistical analysis of the mean of sFas by ELISA test in the patients' groups in comparison to the control revealed a significant increase of both group II and III in comparison to the control group (P < 0.01) but there was no significant difference (P > 0.05) between group I in comparison to either the control or group II. There was a significant difference (P < 0.05) between group I in comparison to group III. LM examination revealed massive extent of the apoptotic cells in group III when compared to both group I and group II. EM examination of the buffy coat revealed apoptotic changes, mainly in the peripheral blood mononuclear cells (PBMNCs), represented by surface membrane ruffles and blebs with clumped nuclear chromatin and vacuolated cytoplasm. In conclusion, this study may help us to better understand one of the escape mechanisms in cancer larynx. This mechanism is represented by the significant increase in both the serum level of sFas and the morphological apoptotic changes that detected in PBMNCs. Soluble Fas may contribute to the progression of laryngeal cancer. It can be used as an attractive target for anticancer therapy and may be considered as a marker of disease progression and poor prognosis in laryngeal cancer.

ABSTRACT Aim The purpose of this study was to evaluate the fracture strength of roots instrumented with the self-adjusting file (SAF; ReDent-Nova, Ra'anana, Israel) and the Reciproc reciprocating file and that were and were not obturated using the warm vertical lateral compaction technique. Materials and methods In total, 75 mandibular premolar teeth were sectioned at or below the cementoenamel junction to obtain roots 13 mm in length. The roots were balanced with respect to buccolingual and mesiodistal diameters and weight. They were distributed into four experimental groups and one control group (n = 15): No instrumentation (group I), instrumentation with SAF files but no obturation (group II), instrumentation with SAF files and obturated with warm vertical lateral compaction (group III), instrumentation with Reciproc File but no obturation (group IV), and instrumentation with Reciproc File and obturated with warm vertical lateral compaction (group V). AH Plus sealer (Dentsply DeTrey, Konstanz, Germany) was used along with gutta-percha points. One week later, a vertical load was applied to the specimen's canal until fracture occurred. Data were statistically analyzed using one-way analysis of variance (p = 0.05). Results The mean fracture load was 312.83 N for group I, 297.35 N for group II, 359.15 N for group III, 231.51 N for group IV, and 275.81 N for group V. Conclusion The fracture resistances exhibited a statistically significant difference between all the groups. Teeth instrumented by SAF exhibited a better fracture resistance.

The purpose of this study was to assess the sternal osteoblastic activity and perfusion in the early period after a coronary artery bypass graft (CABG) using single-photon emission computed tomography (SPECT) and three-phasic dynamic scintigraphy (3PDS) with 99mTc methylene diphosphonate (MDP). Methods: The study group consisted of 57 male patients that were 57.3 ± 6.6 years of age. Thirty-six of them were randomized into two groups: in group I (n = 18), the internal thoracic artery (ITA) was skeletonized, and in group II (n = 18), the ITA was pedicled. All the patients in groups I and II underwent an off-pump CABG using 1.7 ± 0.3 grafts, including one anastomosis of the ITA to the left anterior descending coronary artery. The control group III (n = 21) consisted of patients that underwent mitral valve repair surgery, in whom the sternotomy without the ITA harvesting was performed. The 3PDS and SPECT of the thorax with 99mTc MDP were performed 2 weeks after surgery. Results: The sternal phosphates uptake in group I was approximately twice as high as in group II and approximately 1.5 times higher than in group III (p < 0.05). The MDP uptake asymmetry after the ITA skeletonization was the same as in the group with both intact ITAs. In contrast, after the pedicled ITA harvesting, the osteoblastic activity of the ipsilateral side of the sternum was lower than in the contralateral one. There was no statistically significant difference in scintillation count in the xiphoid process between groups I and II (p > 0.05); however, we observed a significant difference in the manubrium and body (p < 0.05). Conclusion: The main factor that improved the sternal perfusion after a CABG was the preservation of branches supplying the sternum using the skeletonization technique of ITA harvesting.

Background: Visual information acquired through observation plays a pivotal role in learning a movement pattern and motor control. Objectives: This study aimed to analyze the effect of visual deprivation on learning in rats. Methods: The study sample consisted of 12 male rats, divided into three groups. Group I consisted of four rats and was considered the control group. Transection of the two optic nerves was performed on rats of group II on the seventh day after birth and group III on the seventh week after birth to develop the early blind and late blind models, respectively. A T-shaped maze device was utilized to evaluate the learning behavior of rats. Rats of groups II and III were blinded by the optic nerve surgery. In total, 20 trials per day were conducted for nine consecutive days, in which the time and number of correct arm entries were recorded. The ANOVA and Kruskal-Wallis tests were employed to analyze the results in SPSS software (version 16.0). A p-value of less than 0.05 was considered statistically significant. Results: There was a significant difference between the three groups regarding the number of correct arm entries on days one, three, and seven (P<0.05). There was also a significant difference between the three groups regarding how long it took them to enter the target box on days two and three (P<0.05). Group III had a lower number of entries to the target box and it took them a significantly longer time to enter the target box, compared to the other groups. Conclusion: According to the results, visual deprivation may affect the learning of rats during the early days; however, their learning levels increased over the following days. Moreover, the early blinded rats had a higher level of learning than the lately blinded adult rats and the same level of learning as that of the sighted adult rats.

The purpose of this study was to perform the induction and estrous synchronization of Saanen goats in the non-breeding season. The study was conducted from July 2014 - April 2015 on 77 Saanen goats, aged between 1.5 to 5 years. The goats were divided into three experimental groups: in group I (n =37 goats) intravaginal sponge (Ovigest) containing 60 mg of MPA was left in the vagina for 14 days. Immediately after sponge removal the animals received two injections: prostaglandin (Prosolvin) at the dose of 0.75 mg (1 ml)/animal and PMSG hormone (Folligon) at the dose of 500 IU/animal. In group II (n=20) induction and estrous synchronization was performed using synthetic prostaglandin (Proliz - 1 ml containing 0.2 mg isopropyl ester of cloprostenol and 9 mg benzyl alcohol) at the dose of 0.5 ml/animal. The group III (n=20) was considered the control group and estrous synchronization was performed using fertile bucks. In group I the results showed that all goats expressed signs of estrous. The average value of the estrous interval was 33 hours and the average of estrous duration was 20 hours. The number of kids obtained in group I was 94, and prolificacy was P (%) = 2.54. In group II and III was not observed occurrence of estrous. Induction and estrous synchronization show economic benefits by shortening the time needed for pregnancy installation, possibility of births grouping, preparation and organization of mating, only if we use a hormone associated protocol and we rigorous respect therapy steps.

This study evaluated in vitro the capacity of debris removal from the apical third of flattened root canals, using different final irrigation protocols. Thirty human mandibular central incisors with a mesiodistal flattened root were prepared using rotary instrumentation by Endo-Flare 25.12 and Hero 642 30.06, 35.02, 40.02 files, irrigated with 2 mL of 1% NaOCl after each file. The specimens were randomly distributed into 5 groups according to the final irrigation of root canals: Group I: 10 mL of distilled water (control), Group II: 10 mL of 1% NaOCl for 8 min, Group III: 2 mL of 1% NaOCl for 2 min (repeated 4 times), Group IV: 10 mL of 2.5% NaOCl for 8 min, and Group V: 10 mL of 2.5% NaOCl for 2 min (repeated 4 times). The apical thirds of the specimens were subjected to histological processing and 6-μm cross-sections were obtained and stained with hematoxylin-eosin. The specimens were examined under optical microscopy at ×40 magnification and the images were subjected to morphometric analysis using the Scion image-analysis software. The total area of root canal and the area with debris were measured in square millimeters. Analysis of variance showed no statistically significant difference (p>0.05) among the groups GI (2.39 ± 3.59), GII (2.91 ± 2.21), GIII (0.73 ± 1.36), GIV (0.95 ± 0.84) and GV (0.51 ± 0.22). In conclusion, the final irrigation protocols evaluated in this study using the Luer syringe presented similar performance in the removal of debris from the apical third of flattened root canals.
