Papaya cv. Sekaki is one of the Malaysian’s favorite commodities with great tropical taste.
Generally the papaya ripening determined through skin color changes. Current method for
the quality inspection is through the experience of operator. However the inspection from
one operator may vary to another. The main purpose of this study is to improve the quality
inspection of papaya for an efficient grading system. This study will improve the ripening index
developed for papaya by Malaysian Federal Agricultural Marketing Authority (FAMA) on the
skin color basis by comparing the color values between CIE L*a*b* and CIE L*C*h color
space. Destructive technique usually used to evaluate the chemical parameter such as total
soluble solid (TSS) content. A new improvised ripening index chart added with specific TSS
content and color values range. The relationship between color values and TSS was developed
for CIE L*C*h with R²=0.9674. The ripening index chart established allows papaya quality
attributes to be determined and evaluated nondestructively with the aid of colorimeter.

The presence of nurses and junior doctors in the ward environment are crucial, especially in detecting
deteriorating patients. However, there is consistent evidence that warning signs may not always be
identified or acted upon. This paper aimed to analyse the incidence of deteriorating patients, and the
concept of risk assessment of these patients by nurses and junior doctors in general ward, through a review
on relevant literature. An extensive literature search was conducted through online research databases, i.e. CINAHL, MEDLINE (Ovid), Science Direct and ProQuest. Professional journals were hand searched for relevant literature based on reference lists and citations made in key publications, and attempts were also made to obtain any relevant grey literature (unpublished materials). A total of eleven papers which focused on patient’s assessment, response to deteriorating patients and knowledge in medication, and a guideline were reviewed. Most of the studies were carried out in the United Kingdom (n=4), followed by Australia (n=2), Sweden (n=2), the Netherlands (n=1) and Taiwan (n=1). Meanwhile, among these studies, the chosen research designs include, qualitative (n=6), quantitative (n=3) and systematic review (n=1). This review concluded that nurses and junior doctors in general ward have a lack of knowledge in risk assessment of deteriorating patients.
Fulltext Closed tibia fracture. "The effect of an intact fibula and the location of tibia fracture on fracture union"

Ibrahim MM, Mohd R, Ruslan R

Med J Malaysia, 1998 Sep;53 Suppl A:27-34.
PMID: 10968180

Tibial fractures are common and complications occur more frequently than any other long bone fractures. The effect of fibula and location of fracture on union of Tibia fracture remain controversial. A retrospective study of unilateral closed tibial shaft fractures without any associated injury was done. From 1988 to 1992, 74 out of 103 patients were available for the study. There were 60 males and 14 females with the age ranges from 3 to 75 years with an average of 29.7 years. The differences of fractures healing were analyses with respect to the status of the fibula and the location of the tibial fracture. This study concludes that the location of the fracture and the status of the fibula have no significant influence on healing (p > 0.05).

OBJECTIVE: To identify the existing simulation session and the impact of simulation on novice nurse.
METHOD: The articles were searched through CINAHL, Scopus, Proquest, and OVID online database. Articles published from 2000, in English and among novice nurses were selected for review. Then, a narrative review was conducted guided by what are the existing simulation session been used and the impact on novice nurse.
RESULT: Total of 19 articles been selected for review out of 272 articles. The findings of the reviewed were divided into 3 main themes. The themes are the existing simulation session, simulation as a support tool in the transition program and the impact of simulation on novice nurses.
CONCLUSION: In summary, each simulation type has its learning domain. The effectiveness of the simulation will much depend on the appropriate simulation type selection.
Fulltext The use of machine vision technique to classify cultivated rice seed variety and weedy rice seed variants for the seed industry

Seed purity is a crucial seed quality parameter in the Malaysian rice seed standard. The use of
high quality cultivated rice seed, free of any foreign seeds, is the prerequisite to sustaining high
yield in rice production. The presence of foreign seeds such as weedy rice in the cultivated rice
seeds used by the farmers can adversely affect growth and yield as it competes for space and
nutrients with the cultivated rice varieties in the field. Being the most dominant and competitive
element compared to the cultivated rice seeds, the Malaysian seed standard prescribed that the
maximum allowable of weed seeds in a 20-kilogram certified rice seed bag produced by local
rice seed processors is 10 weed seeds per kilogram. The current cleaning processes that rely
mostly on the difference in physical traits do not guarantee effective separation of weedy rice
seeds from the lots. Seed bags found to contain more than 10 weed seeds upon inspection by
the enforcing agency will not be approved for distribution to farmers. The paper describes a
study carried out to explore the use of machine vision approach to separate weedy rice seed
from cultivated rice seeds as a potential cleaning technique for the rice seed industry. The mean
classification accuracies levels of the extracted morphological feature model were achieved at
95.8% and 96.0% for training and testing data sets respectively.

Objective: To audit the amount and complexity of case load and the waiting time for orthodontic treatment in Orthodontic Department of Universiti Kebangsaan Malaysia (UKM).
Materials and Methods: This study involved three waiting list records in Orthodontic department, UKM and 484 patients’ record were selected using Random Sampling technique. Demographic data of the patients were noted. Data on date of patient’s visit to ‘Klinik Rawatan Utama’ (KRU), Screening clinic and first orthodontic treatment (removable/fixed) clinics were also recorded. The severity of referred cases were graded using complexity scale (Russle et al, 1999).
Results: Patients were mostly female (76%) with age ranging from 10 to 52 years old. 75% of the referred cases were complex cases. From the year 2002-2007, 35% were referred for removable and 65% were referred for fixed clinic. In average, orthodontic screening waiting time was 6.9 ± 2.5 month. Patient would received removable and fixed appliance treatment after 4.4 ± 1.0 months and 14.5 ± 9.8 months respectively.
Conclusions: Most patients were referred to fixed waiting list. The waiting time from 2002 until 2007 for orthodontic treatment in UKM was longest for fixed followed by screening. The shortest waiting time was for the removable treatment.

Mutant D311E and K344R were constructed using site-directed mutagenesis to introduce an additional ion pair at the inter-loop and the intra-loop, respectively, to determine the effect of ion pairs on the stability of T1 lipase isolated from Geobacillus zalihae. A series of purification steps was applied, and the pure lipases of T1, D311E and K344R were obtained. The wild-type and mutant lipases were analyzed using circular dichroism. The T(m) for T1 lipase, D311E lipase and K344R lipase were approximately 68.52 °C, 70.59 °C and 68.54 °C, respectively. Mutation at D311 increases the stability of T1 lipase and exhibited higher T(m) as compared to the wild-type and K344R. Based on the above, D311E lipase was chosen for further study. D311E lipase was successfully crystallized using the sitting drop vapor diffusion method. The crystal was diffracted at 2.1 Å using an in-house X-ray beam and belonged to the monoclinic space group C2 with the unit cell parameters a = 117.32 Å, b = 81.16 Å and c = 100.14 Å. Structural analysis showed the existence of an additional ion pair around E311 in the structure of D311E. The additional ion pair in D311E may regulate the stability of this mutant lipase at high temperatures as predicted in silico and spectroscopically.
