Ticks and Tick-Borne Viruses from Livestock Hosts in Arid and Semiarid Regions of the Eastern and Northeastern Parts of Kenya

ABSTRACT Biodiversity and relative abundance of ticks and associated arboviruses in Garissa (northeastern) and Isiolo (eastern) provinces of Kenya were evaluated. Ticks were collected from livestock, identified to species, pooled, and processed for virus isolation. In Garissa, Rhipicephalus pulchellus Gerstäcker (57.8%) and Hyalomma truncatum Koch (27.8%) were the most abundant species sampled, whereas R. pulchellus (80.4%) and Amblyomma gemma Dönitz (9.6%) were the most abundant in Isiolo. Forty-four virus isolates, comprising Dugbe virus (DUGV; n = 22) and Kupe virus (n = 10; Bunyaviridae: Nirovirus), Dhori virus (DHOV; n = 10; Orthomyxoviridae: Thogotovirus), and Ngari virus (NBIV; n = 2; Bunyaviridae: Orthobunyavirus), were recovered mostly from R. pulchellus sampled in Isiolo. DUGV was mostly recovered from R. pulchellus from sheep and cattle, and DHOV from R. pulchellus from sheep. All Kupe virus isolates were from Isiolo ticks, including R. pulchellus from all the livestock, A. gemma and Amblyomma variegatum F. from cattle, and H. truncatum from goat. NRIV was obtained from R. pulchellus and A. gemma sampled from cattle in Isiolo and Garissa, respectively, while all DHOV and most DUGV (n = 12) were from R. pulchellus sampled from cattle in Garissa. DUGV was also recovered from H. truncatum and Amblyomma hebraeum Koch from cattle and from Rhipicephalus annulatus Say from camel. This surveillance study has demonstrated the circulation of select tick-borne viruses in parts of eastern and northeastern provinces of Kenya, some of which are of public health importance. The isolation of NRIV from ticks is particularly significant because it is usually known to be a mosquito-borne virus affecting humans.
INNOVATIVENESS AND INTANGIBLES: THE CASE OF SLOVENIA *

The paper presents the micro data on intangibles for Slovenia in the period 1994–2005 using an augmented method of Corrado et al. (2005) and analyses the role of intangibles in the Slovenian economy during the transition. By examining the organizational, ICT and R&D component of intangibles, we observe a decrease in the value of R&D capital that was to some extent offset by an increase in the value of ICT capital. We find that organizational workers had higher productivity than the average worker. The dynamic of changes was gradual during the transition. The capitalization of intangibles implied an average 4.5% increase of GDP for the new member states. Nonetheless, a worrying convergence can be observed between the tangible and the intangible capital. One can thus expect the intangibles having an important role in the future growth in Slovenia and across the European countries, but only if proper attention is devoted to them in terms of policy measures and regulation.
Evaluating Atypical Features of Femur Fractures: How Change in Radiological Criteria Influenced Incidence and Demography of Atypical Femur Fractures in a Community Setting

Identification of atypical femoral fractures (AFFs) can be challenging. To assist in the radiological assessment, an American Society for Bone and Mineral Research (ASBMR) Task Force developed a case definition for AFFs in 2010, revising it in 2013. How the revised definition performs in a community setting compared with the 2010 definition is unknown. We applied the 2013 criteria to 372 femoral fractures that occurred between January 1, 1996, and June 30, 2009, employing two independent expert physician reviewers. We used radiographs that had been categorized in a previous study on the incidence of atypical fractures using 2010 ASMBR criteria (BEAK1). In this follow‐up study (BEAK2), the same reviewers reviewed all previously identified femoral shaft fractures (FSFs) (n = 197) and distal femur fractures (n = 131) plus a 15% random sample of intertrochanteric fractures (n = 49). After initial review, agreement between the two reviewers ranged from 63% to 100% for specific features, and 84% of radiographs received the same overall classification. Fewer fractures met the 2013 compared with 2010 ASMBR case definition of AFFs (37 per 2013 criteria versus 74 per 2010 criteria). Forty‐three radiographs (58%) categorized as AFFs according to 2010 criteria were no longer AFFs when 2013 criteria were applied, and an additional 12 non‐atypical FSFs according to 2010 criteria were reclassified as AFFs according to 2013 criteria. The major cause of AFF reclassification was the change in the definition of transverse configuration. The modification of the comminution, non‐traumatic, and periosteal/endosteal thickness criteria resulted in the reclassification of non‐atypical FSFs to AFFs. Incidence rate of AFFs according to 2013 ASBMR criteria was lower overall during the 13 years of observation than when the 2010 ASBMR criteria were applied, although we saw a slight increase starting in 2000. As in BEAK1, we found that those with AFFs were younger, more often female, and had a higher exposure rate to bisphosphonates than those with non‐atypical FSFs. As we continue to unravel the demographics of those who suffer from AFFs, our study adds information about how the change in criteria influences epidemiological work. © 2017 American Society for Bone and Mineral Research.
Spontaneous Tumors in Domestic Hamsters

A total of 90 tumors from 85 domestic hamsters (70 Djungarian hamsters and 15 Syrian hamsters) were examined by histology. In the Djungarian hamsters, 64 neoplastic and 11 non-neoplastic lesions were identified, whereas 14 Syrian hamsters showed neoplastic disease, and one showed non-neoplastic disease. The Djungarian hamsters showed a high prevalence of neoplastic disease, similarly to laboratory Djungarian hamsters. In the Djungarian hamsters, almost all tumors were integumental, whereas hematopoietic tumors were the most common type in the Syrian hamsters. The most common integumental tumors in the Djungarian hamsters were mammary tumors, atypical fibromas and papillomas, and a spectrum of integumental tumors that have not been reported in laboratory Djungarian hamsters were identified. Most mammary tumors occurred in the females, whereas all atypical fibromas were observed in the males. In the Syrian hamsters, plasmacytomas and lymphomas were the most common tumors. The small number of Syrian hamsters in this study may reflect the low prevalence of spontaneous tumors seen in laboratory Syrian hamsters. The mean age of the affected hamsters was 19.8 months, which is relatively advanced. To our knowledge, this is the first comprehensive study of tumors in domestic hamsters.
Nutrients and toxicants in rapeseed meal: a review.

The composition of rapeseed meal and hulls is reviewed with emphasis on components of nutritional interest. Carbohydrates in rapeseed meal are mainly pectins, pentosans and cellulose and comprise nearly one-half the gross energy. The digestibility of energy is lower for rapeseed than for soybean meal. Protein is well digested, but the protein digestion coefficient and the availability of amino acids are lower than for soybean meal. Data on digestible and metabolizable energy are summarized. The kinds of glucosinolates present in high (HG) and low (LG) glucosinolate rapeseed meal and the nature of their hydrolytic products are discussed. The toxic effects of oxazolidinethione , isothiocyanates, thiocyanates and nitriles, and their relationship to their parent glucosinolates , to myrosinase action and to conditions during rapeseed processing are reviewed briefly. The effects of glucosinolates in animal tissues and products and the effects of converting to LG rapeseed meal are presented. Finally, a brief review is given of the responses of swine and cattle to the feeding of HG and LG rapeseed meal. The nutritional advantages of LG rapeseed meal, over the older type HG meal, are clearly evident from the feeding trials.
Segregation analysis of mandibular prognathism in Korean orthognathic surgery patients and their families.

OBJECTIVE To investigate the existence of genetic influences on the incidence of mandibular prognathism (MP) in Korean Class III patients. MATERIALS AND METHODS The probands consisted of 100 Class III patients with MP (51 men and 49 women; mean age, 22.1 ± 5.2 years; SNA, 81.2° ± 3.2°; SNB, 84.1° ± 3.9°) who underwent orthognathic surgery. Using three-generation pedigree charts, questionnaires, and clinical examinations, general information and information regarding MP for a total of 3777 relatives of the probands (1911 men and 1866 women) was ascertained. Familial correlations of MP between possible pairs in the pedigree were estimated. Heritability (h(2)) of MP under various models was estimated. Segregation analysis was conducted under the assumption of the nonpolygenic multivariate logistic model and finite polygenic mixed model. One-, two-, and three-susceptibility-type models were evaluated. RESULTS Among 3777 relatives, 199 (97 men and 102 women) were affected with MP (5.3%). Correlation coefficients of MP incidence in full siblings and in parent-offspring were . 2003 and . 2036, respectively (all P < .001). The h(2) of MP was estimated as 21.5% after adjusting for sex and founder effects. Two- and three-susceptibility-type models showed that the general model fit better than the other models. MP incidence did not have a major gene transmission model and was influenced by numerous minor effect genes and their additive effects. CONCLUSION These results suggest that the inherited susceptibility to MP in Korean Class III patients might be due to the summation of minor effects from a variety of different genes and/or influence of environmental factors, rather than Mendelian transmission of major genes.
Mechanisms of inactivation of the p16INK4a gene in leiomyosarcoma of soft tissue: decreased p16 expression correlates with promoter methylation and poor prognosis

The p16INK4a tumour suppressor gene, encoding p16 protein, plays a crucial role in regulation of the G1 cell‐cycle phase. To investigate the potential role of p16 in soft tissue leiomyosarcoma (LMS), an immunohistochemical analysis was performed of 77 LMSs for p16 expression. Decreased expression of the p16 protein was identified in 25 of 77 LMSs (32%). Decreased expression of p16 correlated significantly with large tumour size (p = 0.0038). In a univariate analysis, large tumour size and decreased expression of p16 were statistically significant adverse prognostic factors (p = 0.025 and p = 0.0021, respectively). In a multivariate analysis including conventional clinicopathological parameters, decreased expression of p16 protein was revealed as the only independent unfavourable prognostic factor (p = 0.012). To elucidate the mechanisms of inactivation of the p16INK4a gene, 49 LMSs for which genomic DNA was available were examined; analysis for homozygous deletion, mutation, and promoter hypermethylation was conducted using differential PCR, PCR–SSCP, and methylation‐specific PCR, respectively. Promoter hypermethylation was detected in 11 of 49 LMS cases (22%); homozygous deletion was detected in 3 of 49 cases (6%); and mutation was not recognized in any of the cases studied. Eight of 15 cases (53%) with decreased expression of p16 protein revealed methylation of the p16INK4a gene promoter. Promoter hypermethylation correlated closely with decreased expression and poor prognosis (p = 0.0014 and p = 0.0088, respectively). These results suggest that decreased expression of p16 protein can be considered as an independent reliable prognostic parameter in patients with soft tissue LMS. Furthermore, promoter methylation was more frequent than either homozygous deletion or mutation in this tumour, and promoter methylation was also shown to have a strong association with inactivation of the p16INK4a gene.

Stress does not increase blood–brain barrier permeability in mice

Several studies have reported that exposure to acute psychophysiological stressors can lead to an increase in blood–brain barrier permeability, but these findings remain controversial and disputed. We thoroughly examined this issue by assessing the effect of several well-established paradigms of acute stress and chronic stress on blood–brain barrier permeability in several brain areas of adult mice. Using cerebral extraction ratio for the small molecule tracer sodium fluorescein (NaF, 376 Da) as a sensitive measure of blood–brain barrier permeability, we find that neither acute swim nor restraint stress lead to increased cerebral extraction ratio. Daily 6-h restraint stress for 21 days, a model for the severe detrimental impact of chronic stress on brain function, also does not alter cerebral extraction ratio. In contrast, we find that cold forced swim and cold restraint stress both lead to a transient, pronounced decrease of cerebral extraction ratio in hippocampus and cortex, suggesting that body temperature can be an important confounding factor in studies of blood–brain barrier permeability. To additionally assess if stress could change blood–brain barrier permeability for macromolecules, we measured cerebral extraction ratio for fluorescein isothiocyanate-dextran (70 kDa). We find that neither acute restraint nor cold swim stress affected blood–brain barrier permeability for macromolecules, thus corroborating our findings that various stressors do not increase blood–brain barrier permeability.
Further results on multiple coverings of the farthest-off points

Multiple coverings of the farthest-off points ($(R,\mu)$-MCF codes) and the corresponding $(\rho,\mu)$-saturating sets in projective spaces $PG(N,q)$ are considered. We propose and develop some methods which allow us to obtain new small $(1,\mu)$-saturating sets and short $(2,\mu)$-MCF codes with $\mu$-density either equal to 1 (optimal saturating sets and almost perfect MCF-codes) or close to 1 (roughly $1+1/cq$, $c\ge1$). In particular, we provide new algebraic constructions and some bounds. Also, we classify minimal and optimal $(1,\mu)$-saturating sets in $PG(2,q)$, $q$ small.
Treatment of advanced acute leukaemia with allogeneic bone marrow transplantation from unrelated donors

Summary. Bone marrow transplantation from a histocompatible donor may produce complete remission in patients with induction failure or relapsed acute leukaemia. Through the National Marrow Donor Program, histocompatible bone marrow from unrelated donors has become available for high‐risk patients. In this study we analyse the results of matched unrelated bone marrow transplant in 55 patients with highly advanced acute myelogenous and acute lymphoblastic leukaemia. 28 patients with advanced acute lymphoblastic leukaemia and 27 patients with advanced acute myelogenous leukaemia, age 2–51, were treated withy high‐dose chemoradiotherapy and transplantation of of 6/6 HLA matched (n= 46) or one antigen mismatched (n= 9) unrelated donor bone marrow. After a median follow‐up of 36 months, 13 patients remain alive 17–24 months after transplant for a 2‐year actuarial disease‐free and overall survival of 23 ± 12% (median disease‐free survival 3.5 months). The actuarial risk of relapse is 24 ± 16% at 1 year. Moderate to severe graft‐versus‐host disease occurred in 27/47 evaluable patients (57%). Significant prognostic factors for poor leukaemia‐free survival include age >21, abnormal karyotype, and active leukaemia at the time of transplant. Other pretreatment characteristics such as gender or type of leukaemia were not significant prognostic factors. Our results show that matched unrelated bone marrow transplant for patients with advanced acute bone marrow transplant for patients with advanced acute leukaemia may provide long‐term leukaemia‐free survival, but transplant‐related complications produce a sigbificant impact on survival with older age and adverse disease characteristics predicting for poor prognosis
Ethnic Variation in the Association of Hypertension With Type 2 Diabetes

Lifestyle changes occurring with urbanization increase the prevalence of both type 2 diabetes mellitus (T2DM) and hypertension (HTN). Yemenites who have immigrated to Israel have demonstrated a dramatic increase in T2DM but the prevalence of HTN in diabetic Yemenites is unclear. In a cross‐sectional study, the authors evaluated the prevalence of HTN and lifestyle patterns in Israelis with T2DM of Yemenite (Y‐DM) and non‐Yemenite (NY‐DM) origin. Y‐DM (n=63) and NY‐DM (n=120) had similar age (63±7 vs 64±7 years, P=.5), diabetes duration, diet adherence, and exercise patterns. Y‐DM had a lower prevalence of HTN (63%) than NY‐DM (83%) (P<.01). Furthermore, Yemenite origin was independently associated with lower prevalence of HTN (odds ratio, 0.3; 95% confidence interval, 0.12–0.71). Blood pressure was well controlled with fewer antihypertensive medications in Y‐DM than NY‐DM (P<.01). Even though lifestyle patterns were similar in the two groups, Y‐DM had a lower prevalence of HTN compared with NY‐DM and required fewer antihypertensive medications.
The Retropatellar Portal as an Alternative Site for Tibial Nail Insertion: A Cadaveric Study

Objective: To define spatial relationships between major intra-articular structures of the knee and the entry site of a tibial nail inserted using a retropatellar portal. Design: Cadaveric study using 16 fresh-frozen limbs. Setting: University-affiliated cadaver and anatomy laboratory. Results: The mean distance of the nail entry site and the medial and lateral menisci were 6.6 ± 3.2 mm and 6.4 ± 4.4 mm, respectively. The distance to the medial and lateral articular surfaces were 5.6 ± 3.6 mm and 7.4 ± 4.2 mm, respectively. The mean distance to the anterior cruciate ligament footprint was 7.5 ± 3.5 mm. The lateral meniscus was never injured during the procedure. The anterior cruciate ligament was undisturbed in all specimens. The medial meniscus was injured 1 to 2 mm in 12.5% of specimens. The intermeniscal ligament was injured 1 to 2 mm in 81.2% of the specimens. Conclusion: The intermeniscal ligament and medial meniscus are at the most risk during intramedullary nailing of the tibia using the retropatellar technique. This may be corrected by avoiding an excessively medial start point. Damage to the intermeniscal ligament and medial meniscus occurs more commonly with the retropatellar portal, but this damage was never more than 1 to 2 mm. This risk, however, appears similar to the pattern and incidence of injury that occurred in prior studies investigating tibial nail insertion through a standard patellar tendon approach. The retropatellar technique demands clinical investigation to further define both its safety and its use.
Molecular and cytogenetic studies of an X;autosome translocation in a patient with premature ovarian failure and review of the literature.

We have identified a patient with premature ovarian failure (POF) and a balanced X;autosome translocation: 46,X,t(X;6)(q13.3 or q21;p12) using high-resolution cytogenetic analysis and FISH. BrdU analysis showed that her normal X was late-replicating and translocated X earlier-replicating which is typical of balanced X;autosome rearrangements. Molecular studies were done to characterize the breakpoint on Xq and to determine the parental origin. PCR probes of tetranucleotide and dinucleotide repeat polymorphisms, and genomic probes were used to study DNA from the patient, her chromosomally normal parents and brother, and somatic cell hybrids containing each translocation chromosome. The translocation is paternally derived and is localized to Xq13.3-proximal Xq21.1, between PGK1 and DXS447 loci, a distance of 0.1 centimorgans. A "critical region" for normal ovarian function has been proposed for Xq13-q26 [Sarto et al., Am J Hum Genet 25:262-270, 1973; Phelan et al., Am J Obstet Gynecol 129:607-613, 1977; Summitt et al., BD:OAS XIV(6C):219-247, 1978] based on cytogenetic and clinical studies of patients with X;autosome translocations. Few cases have had molecular characterization of the breakpoints to further define the region. While translocations in the region may lead to ovarian dysfunction by disrupting normal meiosis or by a position effect, two recent reports of patients with premature ovarian failure and Xq deletions suggest that there is a gene (POF1) localized to Xq21.3-q27 [Krauss et al., N Engl J Med 317:125-131, 1987; Davies et al., Cytogenet Cell Genet 58:853-966, 1991] or within Xq26.1-q27 [Tharapel et al., Am J Hum Genet 52:463-471, 1993] responsible for POF.

Diffusion‐weighted magnetic resonance imaging in two patients with polycythemia rubra vera and early ischemic stroke

Polycythemia rubra vera (PRV) is a rare myeloproliferative disorder with a high risk of ischemic stroke. Although thrombosis of large cerebral arteries is the most frequently presumed pathomechanism, various infarct patterns have been described in patients with PRV and ischemic stroke. We report two patients with mild acute ischemic strokes and known PRV, in whom a scattered lesion pattern was detected by diffusion‐weighted magnetic resonance imaging (DWI), but was not visible on computed tomography (CT) and conventional magnetic resonance imaging (MRI). Further diagnostic work‐up including extra‐ and transcranial Doppler sonography (ECD, TCD), transesophageal echocardiography (TEE), magnetic resonance angiography and Holter monitoring revealed no obvious sources of cerebral embolism in both cases. However, TEE in one patient demonstrated spontaneous echo contrast (SEC) in the left atrium. In both patients the symptomatology resolved completely. The detection of a scattered infarct pattern by DWI in patients with PRV and acute ischemic stroke has not been reported previously. DWI findings together with the SEC in one patient emphasize the assumption that a prothrombotic state with subsequent arterial embolism rather than local arterial thrombosis may be the underlying pathomechanism of stroke in some patients with PRV. Adding DWI to the diagnostic work‐up may help to clarify etiology in patients with PRV and acute ischemic stroke.
Type 1 interferons contribute to the clearance of senescent cell

The major known function of cytokines that belong to type I interferons (IFN, including IFNα and IFNβ) is to mount the defense against viruses. This function also protects the genetic information of host cells from alterations in the genome elicited by some of these viruses. Furthermore, recent studies demonstrated that IFN also restrict proliferation of damaged cells by inducing cell senescence. Here we investigated the subsequent role of IFN in elimination of the senescent cells. Our studies demonstrate that endogenous IFN produced by already senescent cells contribute to increased expression of the natural killer (NK) receptor ligands, including MIC-A and ULBP2. Furthermore, neutralization of endogenous IFN or genetic ablation of its receptor chain IFNAR1 compromises the recognition of senescent cells and their clearance in vitro and in vivo. We discuss the role of IFN in protecting the multi-cellular host from accumulation of damaged senescent cells and potential significance of this mechanism in human cancers.
Detection of High-Risk Papillomavirus DNA with Commercial Invader-Technology-Based Analyte-Specific Reagents following Automated Extraction of DNA from Cervical Brushings in ThinPrep Media

ABSTRACT We compared the performances of the Third Wave Technology Invader method and the Digene Hybrid Capture 2 assay to detect high-risk human papillomaviruses in 87 cervical brushing specimens submitted in Cytyc ThinPrep media. Two different methods for the extraction of DNA from squamous epithelial cells were also evaluated.
