The objective of the study was to asses the adhesion of Streptococcus mutans on nanofilled and microfilled composite resin and glass ionomer cement restorative materials. Glass ionomer cements; KetacTM N100 (nanofilled) and Fuji IITM LC (microfilled) and composite resins; FiltekTM Z350 (nanofilled) and FiltekTM Z250 (microhybrid) were packed in acrylic mould of 2 mm thickness and 5 mm diameter. All samples were light-cured and polished with Sof-Lex discs. All materials were cultured with the exponential phase of S. mutans cultivation. Surface roughness values were assessed using Atomic Force Microscope (AFM, Ambios, USA) at time intervals (7hrs, 24 hrs, 7 days, 14 days and 21 days). The morphology of S. mutans on materials was observed after 24 hour incubation of S. mutan on materials under Scanning Electron Microscope (SEM, Quanta FEG 450). Within groups, results showed that both nanofilled materials had lower surface roughness and less adhesion of S. mutans compared to microfilled materials. This study would enhance the clinical knowledge especially in aesthetic area and improve the longevity of the dental restoration.

Donkeys and horses share a common ancestor dating back to about 4 million years ago. Although a high-quality genome assembly at the chromosomal level is available for the horse, current assemblies available for the donkey are limited to moderately sized scaffolds. The absence of a better-quality assembly for the donkey has hampered studies involving the characterization of patterns of genetic variation at the genome-wide scale. These range from the application of genomic tools to selective breeding and conservation to the more fundamental characterization of the genomic loci underlying speciation and domestication. We present a new high-quality donkey genome assembly obtained using the Chicago HiRise assembly technology, providing scaffolds of subchromosomal size. We make use of this new assembly to obtain more accurate measures of heterozygosity for equine species other than the horse, both genome-wide and locally, and to detect runs of homozygosity potentially pertaining to positive selection in domestic donkeys. Finally, this new assembly allowed us to identify fine-scale chromosomal rearrangements between the horse and the donkey that likely played an active role in their divergence and, ultimately, speciation.

PMID: 28439406 DOI: 10.1186/s13620-017-0090-0

BACKGROUND: In horses, the extracranial and intracranial pathway of the internal carotid artery has been described. The extracranial pathway of the internal carotid artery begins at the carotid termination and runs on the dorsal surface of the medial compartment of the guttural pouch. Thereafter the internal carotid artery passes through the foramen lacerum to continue intracranially, forming part of the rostrolateral quadrants of the cerebral arterial circle (Circle of Willis). The objectives of this study were to define and record the anatomy of the carotid arterial tree and the internal carotid artery in donkeys using angiographic techniques. This is a prospective descriptive study on 26 cadaveric donkeys.
METHODS: Twenty six donkey cadavers of mixed, age, sex and use presented for reasons unrelated to disease of the guttural pouch were subjected to carotid and cerebral angiography using rotational angiography. Rotational angiographic and 3 dimensional multiplanar reconstructive (3D-MPR) findings were verified with an arterial latex casting technique followed by dissection and photography.
RESULTS: The following variations of the carotid arterial tree were identified: [1] the internal carotid and occipital arteries shared a common trunk, [2] the linguofacial trunk originated from the common carotid artery causing the common carotid artery to terminate as four branches, [3] the external carotid artery was reduced in length before giving rise to the linguofacial trunk, mimicking the appearance of the common carotid artery terminating in four branches, [4] the internal carotid artery originated at a more caudal position from the common carotid artery termination.
CONCLUSION: Veterinarians should be aware that considerable variation exists in the carotid arterial tree of donkeys and that this variation may differ markedly from that described in the horse.

Nigeria is naturally blessed with wide diversity of native animal genetic resources. Indigenous ruminant livestock such as cattle, camel, donkey, sheep and goat contributes largely in both protein supply, revenue generation and national economy. In Nigeria, these animal resources are mismanaged and undermined through the indiscriminate slaughter of pregnant animals and foetal losses in abattoirs. This unethical practice resulted in the loss of genetic diversity, preferred traits and superior females ruminant animals. The current research focus on reported incidences across abattoirs, which is a centre where such practice is highly occurs within the country. Lack of modern facilities, law enforcement, poor management and animal welfare in abattoirs to protect pregnant animals are among few factors responsible for an increase in incidences. It is unprofitable to continue the tradition of pregnant animal slaughter that causes foetal losses. This is a condition that significantly threatens the animal genetic resources and general livestock industry in Nigeria. This practice must be discard with a proper conservation and documentation of these valuable animal genetic resources. Both long and short terms conservation programs must aim for substantial benefits of these resources. Laws must be enforced with strict penalties to those involved in pregnant animal slaughter. Genetic resources of these species and meat industry future could be safe with proper implementation of these laws and conservation measures.

Introduction: The Ministry of Health Malaysia over the last 20 years has initiated healthy lifestyle campaign to curb obesity but the issue has remained an escalating problem affecting Malaysians. Obesity among students in higher institute is a concern. Undergraduate student nurses as role-model advocating health, being overweight can be a problem. This study is to identify BMI status and determine associated lifestyle factors among undergraduate nurses in UMS. Methods: The study deployed a cross-sectional descriptive survey using a questionnaire to empirically asses BMI status and associated dietary and exercise practice among student nurses. Ethical clearance for the study was ob- tained from UMS`s REC and as well as respondents` consent. A total of 100(N) nursing students were selected through stratified sampling by year of study (year 1, n=35; year 2 n=35; and year 3 n=30). Random sampling for each year of study was done using full name list generated using Microsoft excel. The study tool consists of a validated instrument which captured the respondent’s demographics, BMI index, Healthy Eating Practice Index, and Exercise Practice Inventory. Results: Among the 100 student nurses in this study, 28 students had BMI index of more than 24.9 (either being overweight, obesity Type I or Type II). Students from finalYear 3are significantly overweight(p=0.03) compared to Year 1 or Year 2 students. Comparing respondents with optimum BMI and non-optimum BMI, students who are overweight had significantly poorer Healthy Eating Practice scores and poorer Exercise practice scores. Conclusion: Findings from this study imply that 1 in 4 nursing students are overweight mostly related to poor lifestyle habits. These findings raise the rhetoric and implication of overweight nurses as health care role -models and this paper will discuss some suggestions to address the issue.

The abdominal pelvic cavity has always been regarded as one of the most vulnerable regions of the body. Injuries to this part have been known to be very serious. Based on this a retrospective study was performed on postmortem cases with abdominal and pelvic trauma from 1 October 2002 to 31 January 2003 at the Forensic Institute, Hospital Kuala Lumpur to determine the common pattern of abdomino-pelvic injuries, the injury’s relationship to epidemiological and socio-economic factors, risk organ within the abdominopelvic region and relationship between injuries and survival period. A total of 122 cases abdomino-pelvic were obtained stemming from medico legal postmortems procedures. Results indicated that those aged between 21 to 30 years (38.5%) had the highest incidence of this type of injury. Categorization based on gender showed that males (90.2%) dominated most of the cases. Prevalence based on socio-economic status showed that lower socioeconomy class (52.5%) had the highest incident. This was followed by the middle income (39.3%) and finally the higher income group. The most numerous type of trauma was non-penetrating trauma (94.3%). It was also found that victims with low injury severity score (ISS) had a longer survival period as compared to those with high ISS. It was also noted that victims with two or more region injuries either were spot dead or brought dead. The most common combination of injuries was abdomen, pelvic, chest and limb. In most blunt trauma cases majority of victims had one or two organ involvement while penetrating injuries were difficult to asses. The most common organ involved in this type of trauma was liver (72.1%), pelvic bone (47.5%) and spleen (43.4%). In conclusion, abdomino-pelvic injury is a serious condition and should not be overlooked. Proper attention towards their diagnosis and management is important and so any patient of head injury with coma must be considered as having intra-abdominal injury until proven otherwise.

Objective: The objectives of this study were to asses body mass index, fasting blood sugar , serum cholesterol levels and prevalence of Diabetes Mellitus among outpatients attending the Clozapine clinic at University Malaya Medical Center. Method: 36 patients had their height and weight taken at the start of the study. Their BMI (body mass index) was calculated. Fasting blood sugar, (FBS) and Fasting Serum Lipid (FSL) were performed. Result: The mean body mass index was 24.63. The prevalence of obesity was 13.89%. The prevalence of overweight was 27.8 % and the prevalence of underweight was 5.55%. The prevalence of Diabetes Mellitus was 2.78 %. Serum triglyceride levels appear to be elevated in those receiving Clozapine.Conclusion: It appears that Clozapine may predispose one to obesity. From our study we cannot conclude if Clozapine causes Diabetes Mellitus. However treatment with Clozapine may be associated with elevated levels of serum triglycerides.

In August 2008, 30% of tomato (Solanum lycopersicum) plants in plots in Lubbock County, Texas showed yellowing, lateral stem dieback, upward leaf curling, enlargement of stems, adventitious roots, and swollen nodes. Yellowing in leaves was similar to that seen with zebra chip disease (ZC) of potato that was confirmed in a potato field 112 km away in July 2008 and was associated with a 'Candidatus Liberibacter' species (1), similar to findings earlier in 2008 in New Zealand and California (2,3). Tissue from four symptomatic plants of cv. Spitfire and two of cv. Celebrity were collected and DNA was extracted from midribs and petioles with a FastDNA Spin Kit (Qbiogene, Inc., Carlsbad, CA,). PCR amplification was done with 16S rRNA gene primers OA2 and OI2c, which are specific for "Ca. Liberibacter solanacearum" from potato and tomato and amplify a 1.1-kb fragment of the 16S rRNA gene of this new species (1,3). Amplicons of 1.1 kb were obtained from all samples and these were sequenced in both orientations (McLab, San Francisco, CA). Sequences of the 16S rRNA gene were identical for both Spitfire and Celebrity and were submitted to the NCBI as GenBank Accession Nos. FJ939136 and FJ939137, respectively. On the basis of a BLAST search, sequence alignments revealed 99.9% identity with a new species of 'Ca. Liberibacter' from potato (EU884128 and EU884129) in Texas (1); 99.7% identity with the new species "Ca. Liberibacter solanacearum" described from potato and tomato (3) in New Zealand (EU849020 and EU834130, respectively) and from the potato psyllid Bactericera cockerelli in California (2) (EU812559, EU812556); 97% identity with 'Ca L. asiaticus' from citrus in Malaysia (EU224393) and 94% identity with both 'Ca. L. africanus' and 'Ca. L. americanus' from citrus (EU921620 and AY742824, respectively). A neighbor-joining cladogram constructed using the 16S rRNA gene fragments delineated four clusters corresponding to each species, and these sequences clustered with "Ca. L. solanacearum". A second PCR analysis was conducted with the CL514F/CL514R primer pair, which amplifies a sequence from the rplJ and rplL ribosomal protein genes of "Ca. L. solanacearum". The resulting 669-bp products were 100% identical to a sequence reported from tomato in Mexico (FJ498807). This sequence was submitted to NCBI (GU169328). ZC, a disease causing losses to the potato industry, is associated with a 'Candidatus Liberibacter' species (1-3) and was reported in Central America and Mexico in the 1990s, in Texas in 2000, and more recently in other states in the United States (4). In 2008, a "Ca. Liberibacter solanacearum" was detected on Capsicum annuum, S. betaceum, and Physalis peruviana in New Zealand (3). Several studies have shown that the potato psyllid, B. cockerelli, is a potential vector for this pathogen (2,4). To our knowledge, this is the first report of "Ca. Liberibacter solanacearum" in field tomatoes showing ZC-like foliar disease symptoms in the United States. References: (1). J. A. Abad et al. Plant Dis. 93:108, 2009 (2) A. K. Hansen et al. Appl.

Meat is a rich source of energy that provides high-value animal protein, fats, vitamins, minerals and trace amounts of carbohydrates. Globally, different types of meats are consumed to fulfill nutritional requirements. However, the increasing burden on the livestock industry has triggered the mixing of high-price meat species with low-quality/-price meat. This work aimed to differentiate different meat samples on the basis of metabolites. The metabolic difference between various meat samples was investigated through Nuclear Magnetic Resonance spectroscopy coupled with multivariate data analysis approaches like principal component analysis (PCA) and orthogonal partial least square-discriminant analysis (OPLS-DA). In total, 37 metabolites were identified in the gluteal muscle tissues of cow, goat, donkey and chicken using 1H-NMR spectroscopy. PCA was found unable to completely differentiate between meat types, whereas OPLS-DA showed an apparent separation and successfully differentiated samples from all four types of meat. Lactate, creatine, choline, acetate, leucine, isoleucine, valine, formate, carnitine, glutamate, 3-hydroxybutyrate and α-mannose were found as the major discriminating metabolites between white (chicken) and red meat (chevon, beef and donkey). However, inosine, lactate, uracil, carnosine, format, pyruvate, carnitine, creatine and acetate were found responsible for differentiating chevon, beef and donkey meat. The relative quantification of differentiating metabolites was performed using one-way ANOVA and Tukey test. Our results showed that NMR-based metabolomics is a powerful tool for the identification of novel signatures (potential biomarkers) to characterize meats from different sources and could potentially be used for quality control purposes in order to differentiate different meat types.
