The study of driver posture and comfort in driver workspace is important in vehicle package design especially in two
different type of vehicle, sedan and Multi-Purpose Vehicle (MPV). Due to different seat position in the driver
workspace, investigation of driver accommodation in relations to driver anthropometry is essential to ensure its
meet the ergonomic quality. Therefore, this research is to investigate the preferred driving posture of Malaysian
driver in both sedan and MPV type of car. Sixty two subjects (32 males and 30 females) aged between 17–60 years old
were selected to simulate the comfortable driving posture using mock-ups of sedan car and MPV. Measurements
based on SAE J1100 vehicle package design geometry were carried out for each subject. Result shows slight
differences in the range of posture angle between the two types of vehicles, the posture joint angle in MPV is
slightly smaller as compared to those of sedan car. The range postural angles for Malaysian driver population also is
slightly smaller compare to Caucasian people especially on lower body portion such as knee angle, hip angle and
ankle angle. These angles are due to the body stature and body segment length in which the population of Malaysia
have shorter thighs and legs than those in Europe and America.
We report the unusual case of a dysmorphic child with global developmental delay secondary to a familial complex chromosomal rearrangement (CCR). His chromosomal analysis using G-banding and dual colour fluorescence in situ hybridisation with whole chromosome paint revealed a supernumerary marker chromosome as a result of malsegregation of a familial CCR involving chromosomes 7, 12 and 14. The balanced form of this familial CCR was also carried by the patient's mother and maternal grandmother, both of whom had a history of recurrent spontaneous abortions, as well as his maternal uncle, who was infertile. To the best of our knowledge, this is the first reported case of familial CCR involving chromosomes 7, 12 and 14. This case also highlights the importance of chromosomal analysis in children with dysmorphism and developmental delay as well as in adults who suffer from recurrent spontaneous abortions or infertility.
Microdeletion of the Van der Woude syndrome (VWS) critical region is a relatively rare event, and only a few cases have been reported in the medical literature. The extent of the deletion and the genotype-phenotype correlation are 2 crucial issues.
Rett syndrome (RS) is a severe neurodevelopmental disorder characterised by normal neurological development followed by progressive developmental regression. The X-linked dominant inheritance of RS has been mapped to the gene that encodes the methyl-CpG-binding protein-2 (MECP2) at Xq28. In the present study, denaturing high-performance liquid chromatography (DHPLC) was used to detect mutations in the MECP2 gene in 20 Malaysian RS patients.
Current data indicate that there is a significant risk of endometrial cancer (EC) in women with polycystic ovarian syndrome (PCOS), although further research needed to clarify the exact molecular mechanisms. Endometrial hyperplasia is a premalignant condition that usually heralds EC and it shares identical risk factors with EC. Metabolic syndrome with a triad of obesity, hyperinsulinaemia and diabetes, which is commonly observed in PCOS appears to be a key mechanism in EC pathogenesis. Measures to improve insulin resistance could therefore play a role in reducing the risk of EC in women with PCOS. Metformin is an insulin sensitising agent which is safe, widely available and currently licensed for type-2 diabetes. It has been clearly shown in both animal and human studies that metformin is of value in reversing endometrial hyperplasia. Metformin may therefore prevent EC in PCOS. This article reviews the use of metformin in reducing EC risk in PCOS and makes a case for future research on this topic.
Blau syndrome is characterized by noncaseating granulomatous arthritis, dermatitis, and uveitis, and results from gain-of-function NOD2 mutations. This study was undertaken to identify the genetic cause of the disease in a family with 3 members with Blau syndrome.
