Adulteration of honey and bee-breads in the markets are becoming a matter of deep corncern. The aim of this study, therefore, is to authenticate the natural sources of the honey and bee breads produced by the University of Ilorin Apiary Farm and Jatropha Plantation. A microscopic survey of some pollen breads collected from the Apiary Farm of 6 colonies and Jatropha Plantation of one colony at the University of Ilorin, Ilorin, Nigeria revealed the presence of 9 types of pollens in honey-breads or bee-breads produced by the bees in the area under study. These pollen types include monoporate, salcate, triporate, tricolpate, pericolpate, panporate, biporate, salcate and vesculate. Monorate, colpate, triporate and panporate pollen types are the most frequent occuring in all colonies, followed by salcate, biporate and tricolpate. The least frequent types are pericolpate and vesculate pollens occuring only in the colony A. Density of each of these pollens were also determined in each colony. Some impurities were detected in colonies B, C and E. Panporate pollen of Jatropha curcas is of high frequency in the colony of Jatropha indicating that honeybees visit the Jatropha plants more frequently. So, the honey from the plantation might contain high percentage of panporate pollens. The honey produced at the Apiary and Jatropha Plantation at the University of Ilorin, Ilorin, Nigeria is based on this study. A polyfloral or multifloral type rather than unifloral or monofloral because it contains many types of pollen indicating its source from more than one plant sources or more than one nectars of different entomophilous plants exhibiting the presence of some anemophilous pollens.

Fruit Syndrome

Approximately 30–50% of individuals who are allergic to natural rubber latex (NRL) show an associated hypersensitivity to some plant-derived foods, especially freshly consumed fruits. This association of latex allergy and allergy to plant-derived foods is called latex-fruit syndrome. An increasing number of plant sources, such as avocado, banana, chestnut, kiwi, peach, tomato, potato and bell pepper, have been associated with this syndrome. The prevailing hypothesis is that allergen cross-reactivity is due to IgE antibodies that recognize structurally similar epitopes on different proteins that are phylogenetically closely related or represent evolutionarily conserved structures. Several types of proteins have been identified to be involved in the latex-fruit syndrome. Two of these are plant defence proteins. Class I chitinases containing an N-terminal hevein-like domain cross-react with hevein (Hev b 6.02), a major IgE-binding allergen for patients allergic to NRL. A β-1,3-glucanase was identified as an important latex allergen which shows cross-reactivity with proteins of bell pepper. Another important NRL allergen, Hev b 7, is a patatin-like protein that shows cross-reactivity with its analogous protein in potato. Furthermore, patients with allergy to plant-derived foods and associated pollinosis show a high frequency of IgE reactivity to the pan-allergen profilin, which may cause positive serum IgE determinations to NRL. Although there is much information about the plant-derived foods and some data about the allergens involved in the latex-fruit syndrome, it is not always clear whether latex sensitization precedes or follows the onset of food allergy.

AbstractA new astronomical window into the southern skies has been opened with the high-frequency upgrade to the Australia Telescope Compact Array (ATCA), which allows radio-interferometric mapping of sources at wavelengths as short as 3 mm. In anticipation of the upgrade's completion, a two-day workshop was held at the University of Melbourne in November 2001. The workshop covered a diverse range of fields, tied together by a common theme of identifying key areas where ATCA observations can have an impact. More than half of the talks were concerned with molecular clouds and star formation, with the remainder covering topics such as molecular gas in the Galactic Centre, Seyfert nuclei, and high-redshift objects. Some early results from the 3 and 12 mm prototype systems were also presented. In consultation with the speakers, we are presenting in this article a summary of the talks. The original slides are available from the ATNF website.

AbstractReactions of the lemon leaf-cutting ant, Atta sexdens rubropilosa Forel, to natural sources of allelochemicals has been investigated at the University of Southampton. A linear hypothesis model in a randomized block design of a factorial experiment was utilized to assess the responses of the ants to the treatment combinations. When workers were offered flowers and leaves of the specified plant species simultaneously with mesocarp and endocarp of orange, they exhibited a consistent preference for the flowers. Flower fragments comprised 93.64% of the experimental material brought to the nest, leaves 6.20%, orange mesocarp 0.04% and orange endocarp 0.12%. Deterrent effects were noticed in leaves of Scilla spp. (Liliaceae) and the ants were chemically stimulated to explore, cut and transport the highly attractive flowers of Mahonia aquifolium (Berberidaceae).

Patent Ductus

Background: Patent ductus arteriosus (PDA) treatment is typically pharmacologic, but if unsuccessful, surgical ligation is commonly performed. High-frequency jet ventilation (HFJV) is used at the University of Iowa Stead Family Children’s Hospital for extremely low birth weight infants. Historically, neonates requiring PDA ligation were temporarily transferred to conventional ventilation (CV) prior to surgery. Objective: The objective of this study was to determine whether conversion was necessary. Methods: This retrospective cohort analysis examined outcomes following PDA ligation from 2014 to 2016 at the University of Iowa’s Stead Family Children’s Hospital. Infants who were transferred to CV prior to surgery and returned to HFJV postprocedure are referred to as the CV cohort. The HFJV cohort infants remained on HFJV throughout. Results: We found no significant increases in morbidity or mortality with the use of intraoperative HFJV and potentially show some benefit through greater reduction in serum CO2. Conclusions: Mode of ventilation during PDA ligation does not affect surgical morbidity or mortality or short-term clinical outcomes. Conversion to CV from HFJV is not necessary.

Objectives. The newly developed therapeutic deep heating device can generate deep heat in focal tissue using high-frequency wave stimulation. The objective of this study was to evaluate and compare the effectiveness of this deep heating device (HIPER-500®) with ultrasound in alleviating pain and improving function in patients with shoulder disability. Methods. This noninferiority trial was designed to compare the treatment effect of HIPER-500® to that of SonoStim® (ultrasound) on shoulder pain and disability. Thirty-eight patients with shoulder problems were assigned to either the HIPER-500® or SonoStim® group, and each participated in 10 min therapy sessions, five days a week for two weeks (for a total of ten sessions). Shoulder pain and disability were evaluated using the Visual Analogue Scale (VAS), the University of California at Los Angeles score (UCLA score), the Shoulder Pain and Disability Index (SPADI), and the Constant score in both groups before, immediately after, and four weeks after treatment. Statistical analysis was performed to compare the effects of treatment within and between the groups. Results. A total of 34 patients completed the study. The 18 patients in the HIPER-500® group and 16 patients in the SonoStim® group all showed significant improvements in shoulder pain and function when comparing pretreatment values with the results immediately after treatment and four weeks later. The results before and after treatment did not show a statistically significant difference between the two groups. Conclusions. The newly developed HIPER-500® for high-frequency deep heat therapy showed similar effects to those of SonoStim® for relieving pain and improving physical performance in the patients of this study. HIPER-500® may be a useful modality for treating shoulder pain and improving physical activity in patients with shoulder disease.

This study examines the inhibiting factors affecting reading as a medium of instruction for primary four pupils in the University Practice Primary School (UPPS) at Winneba. Unfortunately, reading which is supposed to be a medium of communication had rather become a challenge by the aforementioned pupils. In this study, both quantitative and qualitative designs have been applied to address this gap. The findings of the study revealed that out of the thirty-two pupils tested, using the 100 high-frequency words for word recognition, only four (4) pupils attained a mastery level of 80%. Thus, rendering the remaining pupils as poor readers. The study recommends that pupils with reading difficulties may need more periods on the academic time table to read in order to overcome their problems. Furthermore, teachers must give much attention to pupils with such challenges. Keywords: Reading, reading performance, Reading challenges, Teaching approaches.
