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

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 In this study, we investigated the importance of netrin-1 levels in ulcerative colitis (UC) in clinical activity of the disease, and its association with other proinflammatory cytokines IL-6 and TNF-α. Methods This study is a type of case–control study. Sixty-seven patients with UC (36 of them activation, 31 of remission) and 50 healthy controls were included in the study. UC patients; ‘Truelove Witts clinical activity index by remission (n = 31), mild activation (n = 21), moderate activation (n = 6) and severe activation (n = 9) were divided into groups. Netrin, IL-6 and TNF-α measurements in plasma samples were performed using enzyme-linked immunosorbent assay kit. Results Between the patient group and the control group; there was a statistically significant difference between netrin-1, IL-6, TNF-α, neutrophil, platelet (p &lt; 0.05 for all). The plasma netrin-1 mean of UC with severe activation group (139.21 ± 48.09 pg/ml) was statistically significantly higher than that of the mild activation (p = 0,037), remission group (p = 0,001) and control group(p = 0,011). The plasma netrin-1 mean of UC with moderate activation group was statistically significantly higher than that of the mild activation(p = 0,045) and remission group(p = 0,004). Conclusion Our results reveal that plasma netrin-1 levels have been shown to be associated with UC activation, similar to proinflammatory cytokines such as TNF-α and IL-6, in UC.

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 Objective: The aim of this case–control study was to compare patients with a healthy peri-implant environment and patients affected by peri-implantitis, evaluating the occurrence of antibodies to extracellular matrix (ECM) molecules. The authors hypothesized the presence of ECM autoantibodies in serum of peri-implantitis patients. Materials and Methods: Patients were divided into two groups: one with dental implants with a diagnosis of peri-implantitis and one control group with implants classified as being “healthy.” Enzyme-linked immunosorbent assay was performed on patients' sera to detect human antibodies to type I, III, IV, and V collagens, laminin, and fibronectin. Fisher exact test was performed to evaluate statistical association, with a significant P < 0.05. Results: Forty-two patients were enrolled in this study, 27 females (64.28%) and 15 males (35.72%) with a mean age of 53 ± 29.69 years (age range 32–74). The presence of antibodies to CIII was recorded in 6/21 (28.57%) patients of test group, compared to just 2/21 (9.52%) for the control group, showing a statistically significant difference (P < 0.05). Other antibodies tested were found to be not statistically significant or absent. Conclusions: Within the limitations of this study, it can be concluded that further studies, with larger sample and different design, are necessary to address the research purpose, evaluating possible associations between anti-ECM antibodies and peri-implantitis.

Abstract Objective. The aim of the present study was to investigate the presence of inflammatory mediators in rats with only periodontitis and periodontitis in a setting of hyper- and hypo-thyroidism and to analyze the correlative linkages between inflammatory mediators and thyroid hormones. Methods. White male 12–14 weeks old inbred rats (n=48) weighing 180–200 g were employed in the experiment. They were randomly divided into the following groups: Group I – control group, Group II – group with a model of periodontitis, Group III – group with a periodontitis in a setting of hyperthyroidism, and Group IV – group with periodontitis in a setting of hypothyroidism. The presence of tumor-necrosis factor-α (TNF-α) and interleukins IL-1β and IL-10 in the periodontal homogenate supernatant was studied by a solid-phase enzyme-linked immunosorbent assay. Results. It was shown that experimental lipopolysaccharide (LPS)-induced periodontitis is accompanied by hyperproduction of pro-inflammatory cytokines (TNF-α, IL-1β) and reduction of anti-inflammatory cytokines (IL-10), whereas TNF-α underwent to maximum changes. Thyroid dysfunction exacerbates cytokine imbalance and severity of inflammation in experimental LPS-induced periodontitis, especially pronounced at hyperthyroidism, as evidenced by the predominance of TNF-α and IL-1β levels in the periodontal homogenate supernatant by 38.5% (р<0.01) and 75.6% (p<0.001), respectively, hyperthyroid over the euthyroid, and by 20.1% (p<0.05) and 24.1% (p<0.05), respectively, over the hypothyroid rats. Conclusions. Thyroid dysfunction, especially hyperthyroidism, may play an important role in the pro-inflammatory response in periodontitis. Hyperproduction of inflammatory mediators in thyroid dysfunction can induce a noticeable damage in the whole apparatus of the periodontium, thereby causing progression of periodontitis.

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.
