Introduction: Diabetes mellitus type 2 is a growing threat in developing countries already burdened with high levels of infectious disease. Screening the general population has debatable advantages. This study aims to determine whether spouses of patients with diabetes mellitus have higher random blood glucose (RBG) levels as well as the benefit of RBG testing as a targetted screening tool. Methodology: The survey employed a cross-sectional comparative study of spouses’ of diabetics and non-diabetics attending the general out-patient department of the LagosStateUniversityTeaching Hospital (LASUTH), Ikeja. A modified WHO STEPS Surveillance Instrument and a one-touch Glucometer were used to collect data. Blood pressures and BMI were measured and correlated to blood glucose levels. Results: Prevalence of high RBG was found to be 7% among spouses of diabetics and 3.3% among spouses of non-diabetic patients. Mean RBG was 5.57 mmol/L and 7.7 mmol/L within the age group 40 - 49 years and 50 - 59 years respectively among spouses of diabetic patients compared to 5.4 mmol/L and 5.5 mmol/L within the same age group among the spouses non-diabetics. Spouses of patients with diabetes mellitus had higher systolic and diastolic blood pressures and BMI compared to spouses of non-diabetics. Conclusion: Being male, married to a diabetic patient, lower educational levels and higher body mass index are significantly associated with higher random blood glucose in the spouses of diabetic patients. Random blood glucose measurements are an effective screening tool and spouses of diabetic patients can benefit from targeted screening in controlled clinical settings.

A finite-difference time-domain approach was used to investigate the excitation of surface plasmons of the circular sub-wavelength apertures on an optical fiber endface. This phenomenon provided the basis of a sensitive liquid refractive index sensor. The proposed sensor is compact and has the potential to be used in biomedical applications, having a sensitivity of （373 ± 16）nm per refractive index unit （RIU） as found through the variation of a reflection minimum with the wavelength.

We report a dual-contrast method of simultaneously measuring and visualizing the volumetric structural information in live biological samples in three-dimensional(3D) space. By introducing a direct way of deriving the 3D scattering potential of the object from the synthesized angular spectra, we obtain the quantitative subcellular morphology in refractive indices(RIs) side-by-side with its fluorescence signals. The additional contrast in RI complements the fluorescent signal, providing additional information of the targeted zones. The simultaneous dual-contrast 3D mechanism unveiled interesting information inaccessible with previous methods, as we demonstrated in the human immune cell(T cell) experiment. Further validation has been demonstrated using a Monte Carlo model.

By changing both the monomer composition and the polymer structure, we have varied the mechanical properties of resorbable polymers. The polymers were synthesized by ring-opening polymerization using L-lactide （LLA）, ε-caprolactone （εCL）, trimethylene carbonate （TMC） and 1,5-dioxepan-2-one （DXO） as monomers. Well-defined triblock copolymers, microblock copolymers and networks have been evaluated, and comparisons between them show that it is possible to tune the mechanical properties. Triblock copolymers with an amorphous middle block of poly（1,5-dioxepan-2- one）（PDXO） and semi-crystalline end-blocks of poly（ε-caprolactone）（PCL） were stronger and had a higher strain at break than triblock copolymers with poly（L-lactide）（PLLA） as end-blocks. Polymers with both DXO and TMC in the amorphous middle-block and PLLA as end-blocks showed a lower stress at break, but the material gained elasticity, a property which is very valuable in tissue engineering. Mechanical properties of networks, synthesized by a novel method, containing PDXO and PCL are also presented. Although it is difficult to compare them with the uncross-linked polymers, this is an additional way to modify and widen the properties.

Sugar beet root maggot （SBRM, Tetanops myopaeformis von R6der） is a major but poorly understood insect pest of sugar beet （Beta vulgaris L.）. The molecular mecha- nisms underlying plant defense responses are well documented, however, little information is available about complementary mechanisms for insect adaptive responses to overcome host resistance. To date, no studies have been published on SBRM gene expression pro- filing. Suppressive subtractive hybridization （SSH） generated more than 300 SBRM ESTs differentially expressed in the interaction of the pest with a moderately resistant （F1016） and a susceptible （F1010） sugar beet line. Blast2GO v. 3.2 search indicated that over 40% of the differentially expressed genes had known functions, primarily driven by fruit fly D. melanogaster genes. Expression patterns of 18 selected EST clones were confirmed by RT-PCR analysis. Gene Ontology （GO） analysis predicted a dominance of metabolic and catalytic genes involved in the interaction of SBRM with its host. SBRM genes function- ing during development, regulation, cellular process, signaling and under stress conditions were annotated. SBRM genes that were common or unique in response to resistant or susceptible interactions with the host were identified and their possible roles in insect responses to the host are discussed.

Q1你的作品非常活泼可爱、童心未泯。能讲讲你的童年生活吗?你小时候是个什么样的孩子,每天都爱做些什么?我像其他所有的孩子一样,充满想象力,而且有使不完的劲儿。不上课的时候我会花大量时间呆在户外。骑单车是我最喜欢的运动,因为我很享受独自起程并且放肆想象的过程。直到现在,我走路时都仍旧习惯去幻想。我认为艺术家们都始终保持着儿时想象的能力,这也是艺术家区别于普通人的重要一点。
