This case report emphasizes the role of Assertive Community Treatment (ACT)in managing a family with four members suffering from mental illness, mainly schizophrenia. We report a case of middle-aged lady who was diagnosed with treatment resistant schizophrenia (TRS) living with two other family members with the same illness and their carer who developed major depression from shouldering the burden of caring for mentally ill family members. ACT, through its holistic approach, proved to have reduced hospitalizations and improve symptom control
and quality of life in this family.

Mitochondrial DNA (mtDNA) is a hereditary material
located in mitochondria and is normally maternally inherited.
Mutational analysis performed on mtDNA proved that the
mutations are closely related with a number of genetic
illnesses, besides being exploitable for forensic identification.
Those findings imply the importance of mtDNA in the scientific
field. MtDNA can be found in abundance in tooth dentin where
it is kept protected by the enamel, the hardest outer part of the
tooth. In this study, two techniques of mtDNA extraction were
compared to determine the efficacy between the two
techniques. Teeth used for the study was collected from Dental
Clinic, Hospital Universiti Sains Malaysia. After the removal of
tooth from the tooth socket of the patient, the tooth was kept at
-20C until use. Later, pulp tissue and enamel was excised
using dental bur and only the root dentin was utilized for the
isolation of mtDNA by crushing it mechanically into powdered
form. MtDNA was extracted using the two published methods,
Pfeifer and Budowle and then subjected to spectrophotometry
DNA quantification and purity, Polymerase chain reaction
(PCR) amplification of hypervariable-two region of mtDNA,
followed by DNA sequencing to analyze the reliability of the
extraction techniques. In conclusion, both techniques proved to
be efficient and capable for the extraction of mtDNA from tooth
dentin.

The crude methanol extracts of Gelsemium elegans leaves were assessed for their cytotoxic activity using the microculture 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cellular viability. This study utilized two different types of human cancer cell lines, CaOV-3 (human ovarian cancer cells) and MDA-MB-231 (human estrogen receptor negative breast cancer cells), allowing for comparison of toxicity of G. elegans against these two cancer cells lines. Our results showed that the methanol extract of G. elegans exhibited high cytotoxicity against the human ovarian cancer cell line CaOV-3 with an IC50 value of 5microg/ml after 96 h incubation. However, G. elegans displayed discernibly less toxicity against the MDA-MB-231 cells with an IC50 value 40microg/ml after 96 h incubation and this effect was dose- and time-dependent, up to 72h and 20-30 microg/ml. In conclusion, our results demonstrated that G. elegans is potently cytotoxic against the human ovarian cancer cell line CaOV-3 and to a lesser extend towards the human breast carcinoma cancer MDA-MB-231 cells, suggesting that the extract is selective towards CaOV-3 cells and may have a chemotherapeutic role for ovarian cancer treatment in the future.

Biocompatibility and growth of osteoblast on bone scaffolds play an important role towards their therapeutic application. The presence of oxidative stress generated by bone scaffolds highly influences osteoblast growth and its functional performance. In this study in-vitro interaction of developed Alginate/Cockle Shell powder nanobiocomposite bone scaffold on osteoblast with regards to cytotoxicity and oxidative stress are evaluated. Cytotoxicity studies using MTT assays revealed a significant increase in viability of cultured osteoblast in the presences of the scaffold extracts. The growth of osteoblast on the scaffold were not deterred with the presence of any major oxidative stress factors as determined through oxidative stress profile studies using SOD, GSH and ROS assays. The nanobiocomposite scaffold evaluated in this study shows promising use in regards to facilitating osteoblast proliferation, growth and viability.

Hypopygiopsis violacea, a species of fly of forensic importance, was recovered from a corpse and described for the first time. The morphological structures of the second and third instar larvae of four specimens were examined using light microscope. Observations were focused on three main morphological characters: cephalopharyngeal skeleton, anterior and posterior spiracles. Cephalopharyngeal skeleton of second instar larva is darkly pigmented and without accessory sclerite below the mouth hook. The anterior spiracles of second and third instar larvae have 8-9 papillae each, arranged in a single row. The posterior spiracle of second instar larva has two spiracular slits with no thickening of peritreme. This differentiates it from the third instar, whereby the latter has three slits for each posterior spiracle. Cephalopharyngeal skeleton of third instar larva is heavily pigmented. An accessory sclerite is found below the hook part of third instar larva but is absent in second instar. Peritreme of the posterior spiracle of third instar larva is thick almost complete encircling a button. The intersegmental spines of the cuticular surface are dome-shaped and unicuspid. Third instar larva of this species is large with size approximately 15 mm long. These findings provide important identification features of immature stages of Hy. violacea which could be useful in forensic entomology.

Abstract. This is the first report of Synthesiomyia nudiseta (Wulp) (Diptera: Muscidae) on a
human corpse discovered in a high-rise building in Malaysia. On 5 March 2008, a decomposing
body of an adult female was found on the top floor of a thirteen-story building in Kuala
Lumpur, Malaysia. Her body was colonized by S. nudiseta larvae, which were normally
associated with corpses found indoors at ground level. The post-mortem interval (PMI) was
estimated at approximately 5 to 9 days. This case is significant as it demonstrates that this
species can locate a dead body even in a high-rise building. Further findings of fly distribution
especially in high-rise buildings should be reported to assist entomologists in PMI analysis.

Background:
What we think we see consists of models constructed in our brains, which may be constrained, limited and perhaps modified at a cerebral level. Patients may view their mirror image differently to how others and the clini‑ cal team view them. Understanding potential variations in perception between real and mirror images is important in clinical practice. The aims were to assess differences in self-perception between frontal facial and mirrored photo‑ graphs, comparing the results with selfie photographs.
Methods:
Facial photographs were taken by one investigator under standardized conditions for preclinical and clini‑ cal students. Each student took a selfie photograph at rest and smiling using his/her smartphone. A mirror image was generated for each image. Each student was shown his/her original and mirror image, without being informed which was which. For each pair of images, students were asked to choose which photograph they perceived as more attractive. A set of photographs of a male volunteer was shown to all participants, to choose either the original or mir‑ ror image as the more attractive.
Results:
Most observers preferred the true image of the volunteer (P < 0.05), which may be evidence that most people prefer the true image of others, which is how they normally view them. Most observers preferred their own original photograph in frontal view at rest and smiling (P< 0.05), but preferred the mirror image of their selfie photo‑ graph at rest and smiling (P < 0.05).
Conclusions
Significant differences in perceptions of attractiveness between true and mirror-reversed frontal and selfie images were found. Observers preferred their image the way they view themselves in a mirror. The selfie is how other people view an individual. If a selfie is flipped horizontally, that is how an individual sees themselves in a mirror. Most observers preferred the mirror image of their selfie, which is how they would view themselves in a mirror.

Parkinson's disease, characterized by motor dysfunction due to the loss of nigrostriatal dopaminergic neurons, is one of the most prevalent age-related neurodegenerative disorders. Given there is no current cure, the stem cell approach has emerged as a viable therapeutic option to replace the dopaminergic neurons that are progressively lost to the disease. The success of the approach is likely to depend upon accessible, renewable, immune compatible, and non-tumorigenic sources of neural progenitors from which stable dopaminergic neurons can be generated efficaciously. Here, we demonstrate that neural progenitors derived from limbus, a regenerative and accessible ocular tissue, represent a safe source of dopaminergic neurons. When the limbus-derived neural progenitors were subjected to a well-established protocol of directed differentiation under the influence of Shh and FGF8, they acquired the biochemical and functional phenotype of dopaminergic neurons that included the ability to synthesize dopamine. Their intrastriatal transplantation in the rat model of hemi-Parkinsonism was associated with a reduction in the amphetamine-induced rotation. No tumor formation was observed 6 weeks post-transplantation. Together, these observations posit limbus-derived neural progenitors as an accessible and safe source of dopaminergic neurons for a potential autologous ex-vivo stem cell approach to Parkinson's disease.
