The present study examined the recent report that transplantation of neonatal striatal tissue into kainic acid (KA) lesioned striatum protected the contralateral striatum from a subsequent KA lesion. We did not find a significant difference in the survival rate of animals that received neonatal striatal transplants into a KA lesioned striatum followed by a subsequent lesion of the contralateral striatum compared to those animals that received bilateral KA-induced striatal lesions alone. The tissue transplants did not protect against the degeneration of striatal neurons induced by KA. Indeed, the survival rate was very low (25%) in the transplant groups. A second experiment was also performed to examine whether a neonatal striatal transplant might reduce the severe syndrome of aphagia and adipsia associated with KA lesions of the striatum. Animals that received the neonatal striatal transplants showed increased aphagia and adipsia compared to animals only receiving the KA lesion. Again, the transplant group had a very low survival rate (10%). The present study was unable to confirm that neonatal striatal transplants protect against KA lesions either by themselves or in conjunction with a recent KA lesion.

The study aims to isolate, characterize, and examine probiotic bacteria's inhibitory ability against Vibrio harveyi bacteria, both in-vitro and in vivo. Methods used in the study consist of 1) An Isolation of Candidate Probiotic Bacteria, 2) An Antagonistic Test of Candidate Probiotic Bacteria in vitro, 3) An Identification of Bacteria, 4) A Pathogenicity Test of Candidate Probiotic Bacteria, 5) An Antagonistic Test of Candidate Probiotic Bacteria against V. harveyi in vivo. According to the isolation of candidate probiotic bacteria, there are 18 isolated candidate probiotic. After being tested for its inhibitory ability in vitro, there are 8 isolates with zone of inhibition as follows: isolate MM 7 from intestine (22 mm), isolate MM 6 from intestine (12 mm), isolate MM 10 from sea water (10 mm), isolate MM 5 from intestine (9 mm), isolate MM 4 from intestine (8 mm), isolate MM 3 from intestine (7 mm), isolate MM 2.2 from intestine (7 mm), isolate MM 2.1 from intestine (7 mm). Eight genera of the candidate probiotic bacteria is derived from Portunid crab, they are Staphylococcus, Streptococcus, bacillus, vibrio, Alcaligenes, Lactobacillus, micrococcus. Before proceeding the V. harveyi bacterial challenge test in vivo, three potential isolates consisting of MM6, MM7 and MM10 as the probiotic bacteria are pathogenicity-tested against V. harveyi. The survival rate of Portunid crab on pathogenicity test using MM6, MM7 and MM10 generates 91.11-100%, while the control generates 100% survival rate. Variance analysis result through post-hoc Tukey's Honest Significant Difference (HSD) test at 95% confidence interval indicates that isolate MM7 and MM10 are significantly able to increase hatchling Portunid crab's survival rate.

AbstractExtra-short implants, of which clinical outcomes remain controversial, are becoming a potential option rather than long implants with bone augmentation in atrophic partially or totally edentulous jaws. The aim of this study was to compare the clinical outcomes and complications between extra-short implants (≤ 6 mm) and longer implants (≥ 8 mm), with and without bone augmentation procedures. Electronic (via PubMed, Web of Science, EMBASE, Cochrane Library) and manual searches were performed for articles published prior to November 2020. Only randomized controlled trials (RCTs) comparing extra-short implants and longer implants in the same study reporting survival rate with an observation period at least 1 year were selected. Data extraction and methodological quality (AMSTAR-2) was assessed by 2 authors independently. A quantitative meta-analysis was performed to compare the survival rate, marginal bone loss (MBL), biological and prosthesis complication rate. Risk of bias was assessed with the Cochrane risk of bias tool 2 and the quality of evidence was determined with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. 21 RCTs were included, among which two were prior registered and 14 adhered to the CONSORT statement. No significant difference was found in the survival rate between extra-short and longer implant at 1- and 3-years follow-up (RR: 1.002, CI 0.981 to 1.024, P = 0.856 at 1 year; RR: 0.996, CI 0.968 to 1.025, P  = 0.772 at 3 years, moderate quality), while longer implants had significantly higher survival rate than extra-short implants (RR: 0.970, CI 0.944 to 0.997, P < 0.05) at 5 years. Interestingly, no significant difference was observed when bone augmentations were performed at 5 years (RR: 0.977, CI 0.945 to 1.010, P = 0.171 for reconstructed bone; RR: 0.955, CI 0.912 to 0.999, P < 0.05 for native bone). Both the MBL (from implant placement) (WMD: − 0.22, CI − 0.277 to − 0.164, P < 0.01, low quality) and biological complications rate (RR: 0.321, CI 0.243 to 0.422, P < 0.01, moderate quality) preferred extra-short implants. However, there was no significant difference in terms of MBL (from prosthesis restoration) (WMD: 0.016, CI − 0.036 to 0.068, P = 0.555, moderate quality) or prosthesis complications rate (RR: 1.308, CI 0.893 to 1.915, P = 0.168, moderate quality). The placement of extra-short implants could be an acceptable alternative to longer implants in atrophic posterior arch. Further high-quality RCTs with a long follow-up period are required to corroborate the present outcomes.Registration number The review protocol was registered with PROSPERO (CRD42020155342).

Little is known about breast cancer in Vietnamese women. Previous studies have reported the frequencies of prognostic factors of breast cancer in this population. The aim of this study was to examine the prognostic factors associated with the survival rates of patients with breast cancer treated at the National Cancer Hospital, Hanoi, Vietnam. We recruited 248 women with operable breast cancer treated with surgery and adjuvant therapy. Tumor tissue samples were stained by many immunohistochemical approaches and analyzed for estrogen receptor, progesterone receptor, and HER2 gene amplification status. A Cox model was used to determine the relationship between survival and the prognostic factors. The disease-free survival rate, overall survival rate, and cancer-specific survival rate were 75.8%, 80.6%, and 86.4%, respectively, at 5 years and 62.3%, 68.1%, and 78.9%, respectively, at 10 years. The lung was the most common metastatic site. Women with factors associated with a poor prognosis (eg, advanced clinical stage, high tumor grade, progesterone receptor [PR] negativity, HER2 amplification) had significantly lower survival rates. Patients with PR-negative breast cancer had significantly worse survival rates compared to those who were PR positive, according to multivariate analysis (hazard ratio = 1.77, 95% confidence interval: 1.01-3.11, P = .045); however, there was only a statistically significant difference in postmenopausal patients. The PR was a prognostic factor in postmenopausal women with breast cancer, but not in premenopausal women.

Delonix regia is commonly called Flamboyant or flame of the forest. The seeds were fermented, boiled, sundried and then ground into powdered meal. 40% crude protein based test diets containing Delonix regia seed meal D0 = 0%; D15 = 15%; D20 = 20% and D25 = 25% inclusion levels respectively were prepared. Red tilapia (Oreochromis niloticus) fingerlings of 6 weeks old were acclimatized for two weeks and then stocked in 12 hapas at 15 fish per hapa measuring 0.6 m × 1.2 m × 0.7 m placed in a concrete tank. Each diet was assigned to fish in a separate hapa in triplicate and administered at 3% fish body weight per day for 16 weeks. Fish weight and length were taken initially, bi-weekly and terminally. Water quality was monitored weekly. Number of fish at the end was recorded and survival rate, growth, feed utilization, fillet yield and blood parameters were determined. The data were subjected to the analysis of variance and mean separation (P= 0.05). Survival rate was highest in fish raised on D20 and least in D25 without any significant difference across the range. Mean growth performances, feed utilization indices and fillet yield were generally congruent between D20 and D25 with varying degrees of significant difference to other feeds. Results of blood assay did not depict harmful effects of the test diets indicating that the fish enjoyed some good measures of health. The gross performance of fish on D20 was optimal. It was therefore concluded that 20% dietary inclusion level of fermented, cooked and dried flamboyant seed was the best for the red tilapia (Oreochromis niloticus) post fingerlings.

Objective. The introduction of CAD/CAM and the development of zirconia-based restorations have allowed clinicians to use less expensive materials and faster manufacturing procedures. The purpose of the study was to analyze the differences, in terms of mechanical and biological complication, in multiunit zirconia fixed dental prosthesis (FPDs) on posterior implants produced using a digital workflow. Method and Materials. This study was a retrospective investigation, and patients treated with screw-retained monolithic or partial veneer FPDs on dental implants were selected. Periapical radiographs were taken at baseline and at the 3-year follow-up. Complications were recorded and classified as technical and biological ones. Results. The study population included 25 patients. The occlusal and interproximal corrections were not clinically significant. In the study sample, the survival rate and success rate of the FPDs after 3 years were 100% and 96%, respectively. One implant failed immediately after placement. Conclusion. Monolithic zirconia FPDs and partial veneer FPDs showed a 100% survival rate, presenting an interesting alternative to metal ceramic restorations. The partial veneer FPDs had a higher technical complication rate than the monolithic FPDs; however, no statistically significant difference was found.

Labeo bata is one of the important minor carps in Bangladesh with great demand as good table fish. The study was conducted to observe the breeding performance at different management practices in Mafatema, Rupali, Modhumoti and Anan fish hatchery and disinfection treatments of water, eggs and fry in Jessore, Bangladesh during 10 March 2014 to 15 May 2015. An improvement in broodstock nutrition and feeding has been shown to greatly improve seed production. Protein and lipid percentage of broodstock diet have been identified as major dietary factors. Protein level was 24.77%, 23.47%, 18.08%, 17.78% and lipid level was 11.07%, 9.50%, 7.74%, 8.14% in Mafatema, Rupali, Modhumoti and Anan fish hatchery respectively. Three concentrations of four chemical-formalin (10, 20, 30 mg/L), malachite green (1, 3, 5 mg/L), NaCl (1, 2, 3 g/L) and methylene blue ( 1, 3, 5 mg/L) treatment regimes and a control were compared for efficacy in treating L. bata eggs to prevent fungus and bacterial infection and improve hatch and survival rate of fry. Highest correlation value between absolute fecundity and body weight (r=.938, p<.05) and total length (r=.891, p<.05) and gonadosomatic index (26.2%) were found in Mafatema fish hatchery among four experimental hatcheries at 24.77% protein and 11.07% lipid level. Better fertilization rate (84.2±5.17%) and hatching rate (82.0±4.30%) were found in Mafatema and Rupali fish hatchery respectively that has significant difference (P<0.05) from that of Modhumoti and Anan fish hatchery at higher protein and lipid level. Lowest deformity rate (6.05+2.65) was observed in Mafatema fish hatchery that was significantly different (P<0.05) from that of Modhumoti fish hatchery. In case of disinfection treatment, methylene blue at 1mg/L bath treatment daily for 4 days showed significantly higher hatching rate (92.33±3.51%) and survival rate (94.33±4.73%).Asian J. Med. Biol.

Introduction: Fluid resuscitation (FR) and massive transfusion protocol (MTP) are important initial strategies for traumatic hemorrhagic shock cases. But poor responded patients to them are difficult to rescue. In such cases, open aortic cross clamping or intra-aortic balloon occlusion (IABO) would be performed as a temporary hemostasis treatment. Recently, IABO for severe trauma has been named resuscitative endovascular balloon occlusion of the aorta (REBOA). But it is still unclear which case can be rescued with REBOA. So we studied the relationship between the responsiveness to FR and REBOA. Methods: Consecutive 46 traumatic hemorrhagic shock patients underwent REBOA at our ER for last 86 months were included. All of their FAST were positive and done FR and MTP as a first-line resuscitation. 10Fr or 7Fr IABO devices were inserted at supraphrenic level (zone I) and underwent fundamental hemostasis by operative management (OM) and/or transcatheter arterial embolization (TAE). They were sorted into responded group or non-responded group for REBOA. The primary end point was a recovery rate from the shock state within 48 hours. Secondary end points were a survival rate in 30th days and a rate of complications. Results: 26 transient or non-responded patients (Fluid Non-responder) responded for REBOA (REBOA Responder group). 20 Fluid Non-responders did not respond for REBOA (REBOA Non-responder group). There were no significant differences in ISS (REBOA Responder vs. Non-responder: 45.8+/-15.2 vs. 54.8+/-22.3), amount of total fluid (7187+/-5782ml vs. 6772+/-4851) and total blood transfusion (4816+/-3006ml vs. 5080+/-3330), required time to occlude after arriving ER (25.3+/-12.6min vs. 19.4+/-9.8) and total occlusion time (76.4+/-66.5min vs. 92.7+/-34.4). There was significant difference in the changes of systolic blood pressure before and after of REBOA (59.3+/-25.7mmHg vs. 38.3+/-39.4, p=0.04). A recovery rate from shock state was 65%(12/26) vs. 0%(0/20) (p<0.01) and a survival rate was 14/26(54%) vs. 0/20(0%) (p<0.01). One complication occurred in REBOA Responder group but was not lethal. Conclusions: It would be necessary to recognize that Fluid Non-responder but REBOA Responder with traumatic hemorrhagic shock could be possible to rescue.

Background: Usage of electronic gadgets like microwave oven is increasing day by day that heats the food by exposing it to electromagnetic radiations which has many hazardous effects on human health including fertility. Aim: To find the effects of microwave oven exposed diet on weight and testis of mice along with protective effects of Mentha Piperita and Melatonin Study Design: Randomized control trial. Methodology: Adult male mice (n=32) were divided into four groups. Control group (G1) received standard pellets prepared for mice. Second group (G2) was given mice pellets exposed to microwave oven. Third group (G3) received Mentha Piperita leaf extract along with mice pellets exposed to microwave oven and the fourth group (G4) received oral melatonin along with pellets exposed to microwave oven. After experimental period, wt of each mice was again recorded and then mice were sacrificed. Data analyzed by SPSS 21.0v. Results: There was no statistically significant difference of weight gain of animals but there was significant reduction in weight of testis in group G2 but in G3 and G4 wt of the testis was close to control. Conclusion: It was concluded that microwave oven exposed diet had no significant effect on overall weight gain of the animal but it significantly reduced weight of the testis in group G2. However, Mentha Piperita and Melatonin both had ameliorative effects on the wt of the testicular tissue. Keywords: Mice, Testis, Weight, Mentha piperita and Melatonin

Background and Aims: Mercuric chloride is highly toxic once absorbed into the bloodstream, especially the kidneys in which it is collected. Mercury chloride increases hydrogen peroxide and enhances the destruction of protective enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPX), leading to oxidative stress. Besides, thymol has anti-oxidant effects and can increase the activity of SOD and GPX. This study aims to evaluate the efficacy of thymol on mercury chloride-induced toxicity. Materials and Methods: In this study, 30 rats, consisting of 6 groups of 5, were used. Control group receiving a single dose of 0.5 mg/kg mercuric chloride for 15 days, third, fourth, and fifth group received intraperitoneal injection of mercuric chloride at a dose of 0.5 mg/kg for 15 days plus thymol at a dose of 10, 30, 50 mg/kg. The sixth group received mercuric chloride at a dose of 0.5 mg/kg for 15 days plus thymol at 30 mg/kg per day for ten days. Results: Results showed a significant difference in the activity of catalase enzyme in kidney tissue samples test. According to the results of SOD, there is a significant difference between the group of corn oil and the group of mercury chloride and between the group of mercury chloride and the group that receives thymol at a dose of 10, 30, 50 mg/kg (p ≤ 0.05). Conclusions: It can be concluded that mercury chloride-induced kidney toxicity and thymol have anti-oxidant protective effects for SOD and GPX.
