Authors: Rohra Neil , Chokshi Jimmy , Sanghavi Rishi
Published: March 2016

Background: The objective of the study was to evaluate functional outcome of open reduction and internal fixation with proximal humeral internal locking system (PHILOS) plate for proximal humerus fractures.

Methods: We reviewed 30 patients who underwent open reduction and internal fixation with PHILOS plate between the years 2010 to 2015. There were 23 men and7 women with a mean age of 36 years (range 20-64).There were 22 patients in the age group of <60 years and 8 patients in the age group of >60 years. According to Neer classification system, 12, 11 and 4 patients had2-part, 3-part, and 4-part fractures, respectively and 2 patients had 4-part fracture dislocation. All surgeries were carried out at our tertiary care trauma center. Functional evaluation of the shoulder at final follow-up was done using Neer’s Evaluation Criteria.

Results: The mean follow-up period was 20 months (range 14-40 months). All fractures united clinically and radio logically. The mean time for radiological union was 13.2 weeks (range 9-26 weeks).At the final follow-up the mean Neer’s Evaluation Criteria was 90 (range 76-100). The results were excellent in 17patients, Satisfactory in 8 patients, Unsatisfactory in 4 patients and Failure in 1 patient. During the follow-up, 3 cases of varus malunion, 1 case of failure of fixation were noted. No cases of AVN, hardware failure, locking screw loosening, infection or nonunion were noted.

Conclusions: PHILOS provides stable fixation in proximal humerus fractures. In order to prevent the complications like avascular necrosis, knowledge of anatomy and vascular supply of head of humerus and good surgical dissection to preserve vascularity of humeral head is important.
Reconstruction of metacarpal bone giant cell tumor by metatarsal bone
Authors: Sau Saikat
Published: March 2016

Giant cell tumour of hand bones is not common especially in metacarpals. Considering its more aggressive behaviour and higher recurrence rate in metacarpals as compared to the other long bones, enblock resection of involved metacarpal is often required. Following resection of metacarpal, the available reconstruction techniques include metatarsal substitution, vascularized or non-vascularized fibular graft, and iliac crest strut graft. We describe a new technique of metacarpal reconstruction using a metatarpal bone and augment with k wire inside it. This new technique ensures good local control of disease, good hand function, maintains aesthetic appearance of hand associated with other reconstruction options.
Enhancing accuracy of autoregressive time series forecasting with input selection and wavelet transformation
Authors: Tran H. D. , Muttil N. , Perera B. J. C.
Published: March 2016

Autoregressive time series forecasting is common in different areas within water resources, which include hydrology, ecology, and the environment. Simple forecasting models such as linear regression have the advantage of fast runtime, which is attractive for real-time forecasting. However, their forecasting performance might not be acceptable when a non-linear relationship exists between model inputs and output, which necessitates the use of more sophisticated forecasting models such as artificial neural networks. This study investigates the performance and potential of a hybrid pre-processing technique to enhance the forecasting accuracy of two commonly used neural network models (feed-forward and layered recurrent neural network models) and a multiple linear regression model. The hybrid technique is a combination of significant input variable selection (using partial linear correlation) for reducing the dimensionality of the input data and input data transformation using discrete wavelet transform for decomposing the input time series into low and high frequency components. Two case study forecasting applications, namely, monthly inflow forecasting for a lake in Victoria (Australia) and weekly algal bloom predictions at a bay in Hong Kong were used to assess the forecasting ability of the models when used in conjunction with the hybrid technique. Results demonstrated that the hybrid technique can significantly improve the forecasting performance of all the models used.

Published: March 2016

Dicephaly is a peculiar type of conjoined twins, which is observed in cattle and other vertebrates. The analysis demonstrates the course and division of arteries of the cranium of a one-day-old two-headed conjoined calf. In comparison with the normal pattern of the bovine cranial vasculature, the arteries of the head of the conjoined animal were considerably modified. The absence of the arteries found in anatomically normal cattle was compensated by very strong, modified linguofacial trunks located at the place where the animals’ heads were conjoined.

Published: March 2016

Interest in iodine complexes has increased significantly in recent years because of their wide spectrum of biological activity. The FS-1 is an ion nanostructured complex formed by proteins and/or polypeptides, carbohydrates, salts of alkali and alkaline earth metals with intercalated iodine. Patented in 2014, it is intended for the treatment of infectious diseases of bacterial origin including nosocomial infections and multidrug resistant tuberculosis. The aim of the study was to determine its acute and subchronic toxicity. The study of acute and subchronic toxicity was performed on adult Wistar rats according to OECD guidelines. The data on acute toxicity showed LD50 > 2,000 mg/kg after a single intragastric administration. Twenty-eight days of FS-1 administration at a dose of 500 mg/kg resulted in toxic effects. At a dose of 250 mg/kg, the toxic effects were temporary and a return to normal followed after the recovery period. Doses of 100 mg/kg had no adverse effects on the rats.

Published: March 2016

The present study compared the quality characteristics of boar semen diluted with three extenders of different proposed preservation times (short-term, medium-term and long-term). A part of extended semen was used for artificial insemination on the farm (30 sows/extender), while the remaining part was stored for three days (16–18 °C). Stored and used semen was also laboratory assessed at insemination time, on days 1 and 2 after the collection (day 0). The long-term extender was used for a short time, within 2 days from semen collection, with the aim to investigate a possible advantage over the others regarding laboratory or farm fertility indicators at the beginning of the preservation time. Viability, motility, kinetic indicators, morphology and DNA fragmentation were estimated. The results showed reduced viability, higher values for most of the kinetics, and higher immotile spermatozoa from day 1 to day 2 in all extenders; however, the long-term extender was superior compared to the other two on both days. With regard to morphology and chromatin integrity, the percentage of abnormal and fragmented spermatozoa increased on day 2 compared to day 1 for all of the extenders. However, based on the farrowing rate and the number of piglets born alive after the application of conventional artificial insemination within 2 days from semen collection/dilution, it was found that the medium-term diluents were more effective. In conclusion, it seems that thein vivofertilization process involves more factors than simply the quality of laboratory evaluated sperm indicators, warranting further research.

Published: March 2016

The aim of the study was to investigate the effect of organic zinc supplementation in calves on serum zinc (Zn) concentrations, selected metabolic profile indicators and serum immunoglobulin (Ig) concentrations. The trial included 2 groups (n = 10) of weaned female calves. The Zn-Methionin calves (group Zn-Met) were supplemented with 30 mg Zn-Met/kg dry matter (DM)/day (BIOPLEX® Zn, Alltech, USA) for 90 days; the control calves (group C) received the same diet without organic zinc supplementation. Compared to the control group, organic Zn treatment significantly increased serum Zn concentration (P < 0.05), superoxide dismutase (SOD) activity (P < 0.01) and total Ig (P < 0.01) in the group Zn-Met at the beginning (7 days from the start of Zn-Met supplementation) of the trial. At the end of the trial (day 90) serum total protein (TP) (P < 0.05), albumin (P < 0.01), urea (P < 0.01), SOD (P < 0.01), copper (Cu) (P < 0.05), Zn (P < 0.01) and Ig (P < 0.05) concentrations were significantly higher in the Zn-Met calves. In the control group alkaline phosphatase (ALP) activity was significantly (P < 0.01) higher on day 90. A positive correlation between zinc concentrations, ALP, and SOD activities in serum, and a negative correlation between zinc and copper concentrations were demonstrated. Dietary Zn-Met supplementation in calves markedly influenced the metabolic profile and serum immunoglobulin concentrations. Compared to the control group, the Zn supplemented group showed a significantly (P < 0.05) lower ALP and significantly greater SOD serum activity (P < 0.01) at the end of the trial. Total Ig concentrations were significantly higher in the Zn treated group (day 7: P < 0.01 vs. day 90: P < 0.05).

Published: March 2016

The objective of this study was to develop a method of preparation and use of vasectomized stallions, and to test them as a factor preventing genital functional disorders in mares during training and hippodrome testing. Thoroughbred mares of English, Arabic and Akhal-Teke breeds owned by horse ranches of the Republic of Kazakhstan were used in the research. Vasectomy techniques were mastered on a slaughtering material, and then field tested on stallions. A series of experiments were set for comparative evaluation of various methods of preparation and use of a vasectomized stallion, resulting in a technique based on removing the front section of sperm ducts in the ventro-caudal portion of the scrotum. The developed method is convenient, safe, and easy to perform in field conditions. The surgery is not time consuming, and there are no postoperative complications. We found a positive effect of the vasectomized stallion on the course of the mares’ oestrous cycles, on their performance during hippodrome testing, and their reproductive function. The method reduced the standing heat period, and the mares quickly recovered their performance. Thus, it decreased the time of the mares’ elimination from the training schedule and had a positive effect on the performance during hippodrome testing. The use of a vasectomized stallion during training significantly predetermined the course of the mares’ reproductive cycle after completion of the hippodrome testing. The results of this study are relevant to the practical needs of sport horse breeding.

The aim of this study was to analyse the effects of different daily intakes of rapeseed bee pollen on the growth and biochemical blood serum indicators in male and female rats. A total of 40 clinically healthy male and female Wistar rats were randomly divided into four groups. In the control group (C) rats were fed a standard complete diet; in the experimental groups standard diets were supplemented with different doses of bee pollen. Treatment group T1 was given standard diet with the addition of bee pollen at a 0.3% concentration; in group T2 the addition was 0.5%; and in group T3 it was 0.75%. The experimental period lasted for 90 days. A significant effect (P < 0.05) of bee pollen on the body weight gain and feed conversion ratio of female rats was found. Significantly (P < 0.05) higher cholesterol concentration in blood serum of male rats was found in the groups with bee pollen addition (groups T2 and T3) compared to the control group. Lower triglyceride serum content in all female experimental groups (T1 and T3) was observed in comparison to the control. Higher serum cholesterol content in the experimental female rats was detected; significant differences were analysed in groups T1 and T3 compared to the control female group. Rapeseed bee pollen at concentrations of 0.5 and 0.75% positively affected the body weight gain of female rats, however, with higher feed consumption (P < 0.05). Rapeseed bee pollen reduced the triglycerides serum content in female rats and increased the cholesterol serum content in male and female rats (P < 0.05).
Artificial environmental radionuclides in Europe and methods of lowering their foodstuff contamination – a review
Authors: Beňová Katarína , Dvořák Petr , Tomko Martin , Falis Marcel
Published: March 2016

This review discusses the consequences of the food chain contamination with radionuclides, especially focusing on the radiocaesium impact after the Chernobyl nuclear accident. In particular, the 137Cs isotope still represents a risk. Until present it is still detectable in the meat of game animals, especially in wild boar, but also in elk and reindeer. Although the occurrence of highly contaminated foods in most of Europe is currently limited, along the German-Czech border (the Šumava Region) the activity concentration of the 137Cs isotope in the meat of wild boar exceeds the acceptable limit several times. Additionally, the article describes simple processing technologies (cooking, pickling etc.) that lead to reduction of radionuclides in contaminated food.

Next‐generation nanoelectronics based on 2D materials ideally will require reliable, flexible, transparent, and versatile dielectrics for transistor gate barriers, environmental passivation layers, capacitor spacers, and other device elements. Ultrathin amorphous boron nitride of thicknesses from 2 to 17 nm, described in this work, may offer these attributes, as the material is demonstrated to be universal in structure and stoichiometric chemistry on numerous substrates including flexible polydimethylsiloxane, amorphous silicon dioxide, crystalline Al2O3, other 2D materials including graphene, 2D MoS2, and conducting metals and metal foils. The versatile, large area pulsed laser deposition growth technique is performed at temperatures less than 200 °C and without modifying processing conditions, allowing for seamless integration into 2D device architectures. A device‐scale dielectric constant of 5.9 ± 0.65 at 1 kHz, breakdown voltage of 9.8 ± 1.0 MV cm−1, and bandgap of 4.5 eV were measured for various thicknesses of the ultrathin a‐BN material, representing values higher than previously reported chemical vapor deposited h‐BN and nearing single crystal h‐BN.

Published: March 2016

As per structural requirement essential for anticonvulsant activity, a series of new 6‐(2‐amino‐substituted phenyl)‐4‐(substituted phenyl)‐1,2,4‐triazine‐3,5‐dione derivatives were designed and synthesized. All the synthesized title derivatives were assessed for in vivo anticonvulsant screening by the two most employed standard animal seizure models, maximal electroshock seizure (MES) and subcutaneous pentylenetetrazole (scPTZ)‐induced seizures, along with minimal motor impairment screening by rotarod test. Among all the synthesized compounds, the compound 4r showed excellent anticonvulsant activity with neither signs of neurotoxicity in the minimal motor impairment test nor signs of hepatotoxicity in the serum enzyme activity assay. The in silico studies of these title compounds were carried out for estimation of a pharmacophore pattern and the prediction of pharmacokinetic properties. To know the exact mechanism of our title compounds, a molecular docking study was carried out on the homology model of sodium ion (Na+) channel and GABAA receptors. The results of the docking study as well as the in vitro study on both the receptors showed that our target compounds best act through the GABAA receptor rather than the Na+ channel receptors. Additionally, GABA enzyme estimation was performed for further confirmation of the mechanism involved in its anticonvulsant activity. Conclusively, the compound 4r presents a novel scaffold in the search for safer and efficient anticonvulsants having neuroprotective as well as GABAergic effects.
