Bioprinting associated with renal in vitro versions: cells, biomaterials, as well as manufacturing techniques. INTRODUCTION Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is a recently described adnexal tumour with a predilection for the face particularly the eye-lids. Considered to be a precursor lesion of mucinous adenocarcinoma, it may represent part of a morphological spectrum. We described a case of this entity, which we believe is the first case to be reported in Malaysia. CASE REPORT A 59-year-old Chinese male presented with a slow-growing cystic lesion over the left lower lateral canthal region. The lesion became progressively larger and nodular within the last 6 months. Histologically, the lesion is a well-circumscribed intradermal tumour with pushing borders extending into the subcutaneous tissue. The tumour cells were arranged in lobules of solid, papillary and cribriform architecture. The cells displayed uniform, medium-sized, round to oval nuclei with stippled chromatin pattern and ample eosinophilic granular cytoplasm. Intracellular mucin (as highlighted by mucicarmine stain) was observed in areas with focal extracellular mucin seen. Mitotic figures were not particularly impressive. By immunohistochemistry study, the tumour cells expressed ER, PR, CK7, GCDFP-15, mammaglobin and EMA diffusely. Chromogranin A and synaptophysin highlighted a significant number of tumour cells. DISCUSSION The morphology and immunohistochemical profile similarities between EMPSGC and solid papillary carcinoma of the breast (SPCOTB) makes the former considered as the cutaneous analogue of the latter. In fact, one should rule out the possibility of metastatic SPCOTB before considering the diagnosis of EMPSGC.INTRODUCTION Malaysia declared its intent to eliminate malaria by 2020, with a phased goal of achieving zero local transmission. Nonetheless, Malaysia is highl susceptible to malaria importation due to geographical proximity to high-burden countries e.g. Thailand, Myanmar and high influx of foreign workers and students from Asia and Africa. CASE SERIES We accumulated all malaria cases diagnosed in a tertiary hospital within a period of two years. Three cases were reported, where all of the patients were foreigners with recent travel history to African countries. All of them were infected by P. falciparum, responded to treatment and discharged well. DISCUSSION This case series highlighted the importance of acquiring recent travel history during history taking and having a high index of suspicions on malaria when dealing with feverish patients originated particularly from African countries.INTRODUCTION Methanol is a widely available chemical with a range of uses including as solvent, as a fuel, in chemical synthesis and anti-freeze preparations. Most of the cases are accidental exposures to drinking beverages contaminated with methanol. MATERIALS AND METHODS In mid-September 2018, there was a single outbreak of methanol poisoning in Malaysia especially involving the state of Federal Territory Kuala Lumpur and Selangor. There were 33 reported deaths suspected due to methanol poisoning in this current outbreak where 11 of them were brought in to the Institute of Forensic Medicine (NIFM), Kuala Lumpur. The last outbreak was in the year 2013 with 29 deaths reported out of 44 cases. RESULTS There were 3 cases (27.2%) died in hospital and the remaining 8 cases (72.8%) were found dead at home and were later brought in dead to the hospital. A full autopsy was carried out for each case. Autopsy findings, as well as lab results pertaining to cases that survived and directly brought in dead, were of a different spectrum. https://www.selleckchem.com/Androgen-Receptor.html CONCLUSION Methanol related deaths are almost always as a result of greed. The running truism is 'methanol poisoning is a result of deliberate addition/adulteration with industrial methanol'. Prevention of the illegal production of methanol and methylated spirits should be established to curb this matter in the future.INTRODUCTION The polycistronic miR-302 cluster encodes five miRNA genes that have an important role in the regulation of embryonic stem cell function. Studies showed that the miR-302 cluster can reprogram both mouse and human fibroblasts to induced pluripotent stem cells (iPSCs) with high efficiency. The aim of this study was to generate an inducible lentivirus that expresses miR-302 cluster in order to further investigate somatic cell reprogramming by these miRNAs. MATERIALS AND METHODS The miR-302 cluster was amplified by polymerase chain reaction technique from human genomic DNA and was ligated into pTRIPz, an inducible lentiviral vector. RESULTS MRC5 fibroblasts and HEK293 (human embryonic kidney) cells were infected with pTRIPz-302 cluster lentivirus and the family of 302 miRNAs were strongly expressed in HEK293 cells but lowly expressed in MRC5 fibroblasts. When cultured in hESC conditions, MRC5 cells expressed only low levels of DNMT3B, Nanog, Oct4 and Lin28 and failed to show stem cell induction. The red fluorescent expression seen in the majority of MRC5 cells, indicated that the rate of infection by lentivirus was efficient. DISCUSSION The efficiency of reprogramming may be improved perhaps by either using a different cell type or a high expression vector with a different type of promoter.INTRODUCTION Autophagy is a mechanism that degrades large damaged organelles and misfolded proteins to maintain the homeostasis in all cells. It plays double-faceted roles in tumourigenesis and prevention of various cancers. In our side observation of investigating the prognostic value of autophagy in colorectal cancer (CRC), we found high expression of autophagy proteins (LC3A, LC3B, and p62/SQSTM1) in the colonic ganglion cells. To our best understanding, this is the first paper reporting such finding. MATERIALS AND METHODS Formalin-fixed paraffin-embedded (FFPE) CRC tissues blocks were retrieved and confirmed by haematoxylin & eosin (H&E) staining. Immunohistochemistry (IHC) targeting autophagy proteins (LC3A, LC3B, and p62/SQSTM1) was then performed followed by pathological examination. RESULTS All three autophagy proteins were present in both normal and tumour tissues of CRC patients. https://www.selleckchem.com/Androgen-Receptor.html Interestingly, high expression of autophagy proteins in colonic ganglion cells was consistently seen regardless of tissue type (normal or cancer) or tumour site (caecum, ascending, transverse, descending, sigmoid colon and rectum).
