Gifted and talented students are different from the other normal students and special attention is needed for due to their high cognitive ability and their socio-emotional conditions. Literatures show shortcomings and ineffectiveness of the counselling services to the gifted and talented students. The lack of effective interventions and approaches targeted to the students hinders the understanding on the importance of counseling services to the students. Hence, this study aims to explore the school counseling services for gifted and talented students. Based on inclusion and exclusion criteria, 10 articles were selected and reviewed. Findings from different journal sources conducted in different countries were assimilated to attain better understanding of the relevance of school counseling services to gifted and talented students. The role of the school counselors and the challenges in the school counseling services were also identified from the articles.

In this review we summarize the progress made towards understanding the role of protein-protein interactions in the function of various bioluminescence systems of marine organisms, including bacteria, jellyfish and soft corals, with particular focus on methodology used to detect and characterize these interactions. In some bioluminescence systems, protein-protein interactions involve an "accessory protein" whereby a stored substrate is efficiently delivered to the bioluminescent enzyme luciferase. Other types of complexation mediate energy transfer to an "antenna protein" altering the color and quantum yield of a bioluminescence reaction. Spatial structures of the complexes reveal an important role of electrostatic forces in governing the corresponding weak interactions and define the nature of the interaction surfaces. The most reliable structural model is available for the protein-protein complex of the Ca(2+)-regulated photoprotein clytin and green-fluorescent protein (GFP) from the jellyfish Clytia gregaria, solved by means of Xray crystallography, NMR mapping and molecular docking. This provides an example of the potential strategies in studying the transient complexes involved in bioluminescence. It is emphasized that structural studies such as these can provide valuable insight into the detailed mechanism of bioluminescence.

BACKGROUNDBifurcation angles may have an impact on the clinical outcomes of crush stenting. We sought to compare high (> or = 60 degrees ) with low (< 60 degrees ) bifurcation angle in patients who underwent either classical or double kissing (DK) crush stenting for bifurcation lesions from the DKCRUSH-1 data base.

METHODSThere were 212 patients with 220 lesions, some with low-angle (n = 138) and some with high-angle (n = 74). Angiography was indexed at 8-month after procedure. Primary endpoint was the occurrence of major adverse cardiac events (MACEs), defined as cardiac death, myocardial infarction and target lesion revascularization (TLR). Secondary endpoint included late lumen loss, the rate of restenosis, and final kissing balloon inflation (FKBI).

RESULTSAt 8 months, clinical follow-up was 100%; angiographic follow-up was 75% in the low-angle group and 83.3% in the high-angle group. There were no significant differences in the FKBI between the high-angle group (91.43%) and the low-angle group (82.39%). In the high angle group, there was a significant difference in contrast volume used (P = 0.005) but no significant difference in acute gain, minimum lumen diameter (MLD), late loss and diameter stenosis in the pre-bifurcation segment, post-bifurcation segment or side branch. When lesions were assigned into with-(n = 133) and without-FKBI (n = 42), significant side-branch late loss was seen in the group without-FKBI ((0.65 +/- 0.49) mm vs (0.47 +/- 0.62) mm, P = 0.02), with a resultant greater restenosis rate (37.68% vs 18.32%, P = 0.001). No difference was detected in the MACE free survival rate between the high and low angle groups (82.39% vs 82.36%, P = 0.84). The rate of stent thrombosis tended to be higher in the lower-angle group although there was no significant difference (P = 0.38). The TLR free survival rate was 87.2% in the with-FKBI group vs 73.5% in the without-FKBI group (P = 0.001). Cox regression analysis showed that the independent predictors for target vessel revascularization were the side branch stent MLD post stenting (hazard ratios (HR) 1.028, 95% CI 2.357 - 16.233, P = 0.002), lack of FKBI (HR 4.910, 95% CI 4.706 - 8.459, P = 0.001) and unsatisfactory kissing (HR 3.120, 95% CI 2.975 - 5.431, P = 0.001).

CONCLUSIONSBifurcation angles do not influence the clinical outcome of crush stenting. Successful final kissing balloon inflation, regardless of bifurcation angles, can predict TLR.

OBJECTIVETo determine independent factors correlated with clinical effects of DK crush and classical crush technique with drug-eluting stents on bifurcation lesions.

METHODS311 patients with bifurcation lesions were randomized to classical (C, n = 156) or double kissing (DK) crush (n = 155) stent implantation group. The primary endpoints included major adverse cardiac events (MACE).

RESULTSFinal kissing balloon inflation (FKBI) success rate was 76% in C and 100% in DK groups (P < 0.001). DK crush procedure was characterized by lower unsatisfactory FKBI rate (27.6% vs.6.3%, P < 0.01). Clinical follow-up was available in 100% and angiographic follow-up in 82% patients. The overall restenosis rate was 32.3% in C and 20.3% in DK groups (P = 0.01), respectively. Cumulative 8-month MACE was 35.9% in without-FKBI and 19.7% in with-FKBI sub-groups, and 11.4% in DK group (P = 0.02). The incidence of stent thrombosis was 3.2% in C group (5.1% without vs. 1.7% with FKBI) and 1.3% in DK group (P > 0.05). The predictive factors of MACE included minimal side branch stent lumen diameter and lack of DK crush technique.

CONCLUSIONDK crush technique is an alternative of double stenting techniques in terms of improvement of restenosis and clinical outcomes.

Objective: To characterize the Entamoeba histolytica (E. histolytica) antigen(s) recognized by moribound amoebic liver abscess hamsters. Methods: Crude soluble antigen of E. histolytica was probed with sera of moribund hamsters in 1D- and 2D-Western blot analyses. The antigenic protein was then sent for tandem mass spectrometry analysis. The corresponding gene was cloned and expressed in Escherichia coli BL21-AI to produce the recombinant E. histolytica ADP-forming acetyl-CoA synthetase (EhACS) protein. A customised ELISA was developed to evaluate the sensitivity and specificity of the recombinant protein. Results: A ~75 kDa protein band with a pI value of 5.91-6.5 was found to be antigenic; and not detected by sera of hamsters in the control group. Tandem mass spectrometry analysis revealed the protein to be the 77 kDa E. histolytica ADP-forming acetyl-CoA synthetase (EhACS). The customised ELISA results revealed 100% sensitivity and 100% specificity when tested against infected (n=31) and control group hamsters (n=5) serum samples, respectively. Conclusions: This finding suggested the significant role of EhACS as a biomarker for moribund hamsters with acute amoebic liver abscess (ALA) infection. It is deemed pertinent that future studies explore the potential roles of EhACS in better understanding the pathogenesis of ALA; and in the development of vaccine and diagnostic tests to control ALA in human populations.
