Increase in cross-sectional muscle area of major muscle groups associated by heavy resistance training
has been well documented. However, there has been no published article of changes in the inferior
orbicularis oculi muscle when heavy resistance training is applied. We present a case of inferior
orbicularis hypertrophy detected on MRI in a gentleman who practised heavy resistance training
using his lower eyelids.

OBJECTIVETo investigate the prevalence of container breeding mosquitoes with emphasis on the seasonality and larval habitats of Aedes aegypti (Ae. aegypti) in Makkah City, adjoining an environmental monitoring and dengue incidence.
METHODSMonthly visits were performed between April 2008 and March 2009 to randomly selected houses. During each visit, mosquito larvae were collected from indoors and outdoors containers by either dipping or pipetting. Mosquitoes were morphologically identified. Data on temperature, relative humidity, rain/precipitations during the survey period was retrieved from governmental sources and analyzed.
RESULTSThe city was warmer in dry season (DS) than wet season (WS). No rain occurred at all during DS and even precipitations did fall, wetting events were much greater during WS. Larval survey revealed the co-breeding of Aedes, Culex and Anopheles in a variety of artificial containers in and around homes. 32 109 larvae representing 1st , 2nd, 3rd, and 4th stages were collected from 22 618 container habitats. Culicines was far the commonest and Aedes genus was as numerous as the Culex population. Ae. aegypti larval abundance exhibited marked temporal variations, overall, being usually more abundant during WS. Ten types of artificial containers were found with developing larvae. 70% of these habitats were located indoors. 71.42% of indoor containers were permanent and 28.58% was semi-permanent during WS. Cement tanks was the only container type permanent during DS. Ae. aegypti larval indices (CI, HI, BI) recorded were greater during WS.
CONCLUSIONSTaken together, these results indicate a high risk of dengue transmission in the holy city.

Aims:
This present study focused on purification of fungal β-mannanase produced by Aspergillus niger USM F4 and
also physicochemical characterisation of the purified enzyme.
Methodology and results:
The purified β-mannanase with a molecular mass of ~47.4 kDa was demonstrated on SDSPAGE gel. The enzyme signified a purification degree of 4-fold, with final specific activity of 196.42 U/mg. It reached an
optimum catalytic activity at pH 4.0 and 60 °C. The thermal stability of the enzyme was up to 70 °C and maintained the
50% activity after 30 min at 80 °C. Meanwhile, the pH stability was in the range of pH 3.0-9.0 and a 30 min half-life at pH
10.0. All chemical substances manifested an inhibitory effect on purified β-mannanase, with SDS (28.16 ± 0.05%
residual activity) as the strongest inhibitor, followed by cupric ion (Cu2+) (49.51 ± 0.09% residual activity). As a whole, the
enzyme displayed a substrate specificity in the order of locust bean gum (LBG) > carboxymethylcellulose > soluble
starch > xylan from oat spelt > α-cellulose. Its preference for LBG has generated the Km and Vmax values of 0.20 mg/mL
and 9.82 U/mL, respectively.
Conclusion, significance and impact of study
The outcomes of our study offer potential for use at industrial scales,
particularly in the oligosaccharides production that involve acid-related activity, wide-ranging temperature and pH
stability.

Colorectal cancer (CRC) carries a significant burden in most world regions. However, its screening uptake remains low. This study aimed to explore awareness and perspectives on CRC screening program in a multiethnic population and their preference for CRC screening decision aid. In-depth interviews were conducted until data saturation was reached. All interviews were audiotaped, transcribed verbatim, translated to English and analysed thematically using hybrid inductive and deductive approaches. 17 informants from three main ethnic groups (Malay, Chinese and Indian) with various levels of risk for developing CRC were recruited. Awareness on CRC screening program was found to be low. Majority of informants never heard of CRC screening program. Among 11 eligible informants, only five experienced CRC screening uptake. Thematic analysis of the transcripts yielded six major themes; knowledge on CRC, screening process, authority’s role, curability, willingness to screening and preference for decision aid, and theywere mapped onto the Health Belief Model. Specific multiethnic perspectives found included preference for traditional medicine coming from all ethnics, and reliance in God coming from Malay informants. Majority preferred short videos as CRC screening decision aid, in the form of animation and live-action screenplay. Exploration of perspective of CRC screening helps in producing impactful decision aids. Future efforts should focus on developing short videos that incorporate population’s perspectives and can be disseminated through electronic media.
